The golf course consists of a tee ground where the golfer hits the golf ball for the first time, a green with a hole cup, and a fairway between the tee and the green. Generally, the green is not much tilted, but the fairway has various obstacles such as bunkers, hazards and water hazards, and the fairway itself has a constant slope. Also, it is designed to be difficult to hit the next time unless the fairway or green is hit accurately by adjusting the length of the grass in the rough part and green around the fairway as well as the slope in the area.

In order to accurately simulate a real golf course, the necessity of simulating the inclination of each course accurately at the part where the golfer swings is required, because the inclination of the fairway varies depending on the terrain, including the bunkers and hazards existing in each course. do.

Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

A schematic view of the overall structure of a swing plate S according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the drawings, a bidirectional hydraulic generator 100, a modular actuator 200, a tilt adjusting cylinder 300, 400, and the pivot joint 500, as shown in FIG.

Hereinafter, the present invention having the above-described schematic configuration will be described in more detail for facilitating the implementation.

The bidirectional hydraulic pressure generator 100 of the present invention is provided with a pair of front and rear sides of a top surface of a base plate 10 fixed to the floor and the pair of bidirectional hydraulic pressure generators 100 each have two inclination adjusting cylinders 300 at the same time.

The bidirectional hydraulic pressure generator 100 includes a pair of cylinder supporting plates 110 mounted on the upper surface of the base plate 10 so as to penetrate through both sides of the cylinder 120 and integrally fixed to the inside of the cylinder 120, 7 to 8, the first piston rod 140 connected to one side of the piston 130 is arranged to be able to transmit power to the modular actuator 200 And the screw shaft 220 is fitted to the tip end of the first piston rod 140. The screw shaft 220 is inserted into the end cap 121 through the end cap 121, (Not shown).

A pair of hydraulic ports 124 and 124a are coupled to the hydraulic chambers 123 and 123a formed on both sides of the piston 130 and the pair of hydraulic ports 124 and 124a are connected to a hydraulic pressure source The hose 125 is connected to two different inclination adjusting cylinders 300 so that the hydraulic pressure can be simultaneously supplied / collected to the two inclination adjusting cylinders 300 facing each other.

Here, the present invention is further combined with a technique for maintaining the same hydraulic pressure at all times without providing a separate tuning side in the process of supplying / recovering hydraulic pressure to / from the bidirectional hydraulic pressure generator 100 at the same time.

A second piston rod 150 is further connected to the other side of the piston 130 and the second piston rod 150 is connected to an end cap 121a coupled to the other end of the cylinder 120 And the first and second piston rods 140 and 150 are formed to have the same size and the same diameter so that the both side oil pressure chambers 123 and 123a maintain the same volume The hydraulic pressure of the same pressure can always be supplied / recovered, thereby providing an effect that the inclination of the swing plate S can be controlled more smoothly.

The piston 130 and the first and second piston rods 140 and 150 of the present invention may be formed as a single body, but each of the piston 130 and the first and second piston rods 140 and 150 may be separately formed separately in consideration of difficulty in machining them integrally. It is more preferable to form a structure that can be assembled and integrated. Therefore, a differentiated assembly structure is disclosed in the present invention.

The first piston rod 140 for the first piston rod 140 is formed with a step between the insertion support portion 141 and the screw portion 142. The piston 130 has first, Insertion recessed portions 132 (132a) for supporting the second piston rods (140) (150) in an inserted state are formed in a recessed manner.

The insertion support portion 141 of the first piston rod 140 is inserted into and supported by one insertion recess 132 and the threaded portion 142 passes through the insertion hole 131 and the other insertion recess 132a The threaded portion 142 is screwed into the threaded hole 151 formed at the tip of the second piston rod 150 in a state where one side of the second piston rod 150 is inserted into the other side recessed portion 132a, So that the piston 130 and the first and second piston rods 140 and 150 can be integrally formed with each other by a simple assembly method.

The first piston rod 140 exposed to the outside of the bidirectional hydraulic pressure generator 100 is directly transmitted to the piston 130 in a straight line so that smooth operation of the bidirectional hydraulic pressure generator 100 can be improved The modular actuator 200 as a core technology of the present invention is installed in series so that the modular actuator 200 converts the rotational power of the screw shaft 220 driven by the decelerating motor 210 into linear motion, And directly to the first piston rod 140 of the hydraulic pressure generator 100 in the same straight line.

The structure of the modular actuator 200 according to the present invention is divided into components of the deceleration motor 210, the screw shaft 220, and the anti-rotation guide plate 230.

The decelerating motor 210 is attached to a motor supporting plate 212 vertically coupled to one side of a base bracket 211 fixed to the upper surface of the base plate 10, The other end of the screw shaft 220 is connected to the first piston rod 140 of the bidirectional hydraulic generator 100 coupled to the other side of the base bracket 211, And is screwed through the shaft coupling hole 144 formed at the tip of the shaft.

The screw shaft 220 can be directly screwed to the shaft coupling hole 144 and the linear movement holder 147 is further integrally coupled to the shaft coupling hole 144. In this case, The shaft 220 is not threaded directly to the shaft coupling hole 144 but is threaded through the linear movement holder 147 to prevent frictional resistance between the shaft shaft 220 and the shaft coupling hole 144, 1 piston rod 140 can more smoothly linearly move.

A rotation preventing plate 230 is integrally fitted to the outer side of the first piston rod 140 and a pair of guide rods 235 are provided on both front and rear sides of the motor supporting plate 212 and the cylinder supporting plate 110, The front and rear sides of the anti-rotation guide plate 230 are coupled through the guide rod 235 so that the anti-rotation guide plate 230 slides left and right along the guide rod 235 Thereby preventing the first piston rod 140 from rotating.

The rotation prevention guide plate 230 converts the rotational motion of the screw shaft 220 into a linear motion while guiding the linear movement of the first piston rod 140 so that the screw shaft The piston 130 is smoothly linearly moved to greatly improve the operability of the swing plate S and the distortion of the piston 130 is eliminated, So that the durability can be remarkably improved.

The bidirectional hydraulic pressure generator 100 integrally coupled to the modular actuator 200 is configured such that the lower side of the cylinder supporting plate 110 is coupled with the base bracket 211 through the fastening hole 113, The cylinder supporting plate 110 and the base bracket 211 are separated from each other as shown in FIG. 9 so that the bidirectional hydraulic generator 100 and the modular actuator 200 can be individually separated and partially replaced .

In other words, since the modular actuator 200 and the bidirectional hydraulic pressure generator 100 are separated from each other, it is possible to separate and partially replace only the corresponding components at the time of breakage, thereby providing a special effect that A / S is very easy.

A plurality of tilt adjusting cylinders 300 are installed on the four sides of the base plate 10 and the tilt adjusting cylinder 300 is connected to the bidirectional hydraulic pressure generator 100 via a hydraulic hose 125 to receive hydraulic pressure The inclination of the swing plate S can be freely adjusted.

The tilt plate 400 is mounted on the upper end of the inclination adjusting cylinder 300 and the pivot joint 500 installed at the center of the upper surface of the base plate 10 is integrally coupled to the bottom surface of the tilt plate 400 And the pivot plate 400 can be rotatably supported. The pivot joint 500 has a freely rotatable structure like a known retaining joint.

Here, the slope adjusting cylinder 300 is further combined with a new concept of reducing the occurrence of abrasion by dispersing the frictional resistance concentrated on the plate 400 when adjusting the inclination.

10, a ball joint 310 is installed at the upper end of the piston rod 301 and the ball joint 310 is provided at an upper portion of the socket 311 with an inclination The free swivel plate 320 passes through the bottom surface of the swash plate housing 330 integrally attached to the bottom surface of the batter seat plate 400 and is inserted into the free space 331 ).

The ball joint 310 can freely rotate at the same time and maintain various degrees of inclination while the socket 311 provided to surround the upper portion of the ball stud 312 freely rotates to freely rotate the free swash plate 320 coupled with the socket 311 .

The free swivel plate 320 is not integrally attached to the bottom surface of the bass plate 400 and is kept free to move in four directions in the free space 331 so that when the inclination of the swing plate S is adjusted, The life of the batting plate 400 is greatly extended to provide a special effect of further improving durability.

In the meantime, the present invention is applied to a safety driving device 600 that restricts excessive movement of the piston 130 and allows the swing plate S to maintain an inclination only within a set safety range.

11, a switch contact portion 610 is integrally attached to one side of the anti-rotation guide plate 230, and both sides of the switch contact portion 610 are connected to the base plate 10 And a pair of limit switches 630 attached to both sides of the inner surface of the mounted control module case 620. When the switch contact strip 610 is moved to the left and right, either one of the limit switches 630 The overload of the deceleration motor 210 and the breakage of various components are prevented by automatically stopping the operation of the deceleration motor 210 or generating an alarm at the moment of the grounding of the swing plate S, do.

In the meantime, the present invention is applied to a technique of automatically maintaining the horizontal position by correcting a wrong position of the batter plate 400 when the swing plate S is initially powered on.

A variable resistor 700 is attached to the center of the control module case 620 and a pinion gear 710 coupled to the rotary shaft 701 of the variable resistor 700 is connected to the switch contact 610 And a pair of photo interrupters 730 are mounted to face the inner sides of both sides of the center of the control module case 620. The photo interrupter 730 is mounted on the pinion gears 720, (710) and counts the rotation value.

Accordingly, when the power of the swing plate S is turned on, the variable resistor 700 confirms the horizontal state. When the swing plate S is not horizontal, the angle of the batter plate 400 is maintained to be horizontal, The photointerruptor 730 measures the state of deformation and uses it as a correction value in the case of an angle implementation. If the degree of deformation is so large that an abnormality may occur during operation of the swing plate S, .
