The present invention will be described below with reference to FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 respectively.

Fig. 2 provides a schematic diagram of a rotation control circuit for the underframe of a piggyback transport vehicle. As shown in Fig. 2, the circuit includes a power control circuit, a potential distribution circuit and a solenoid valve circuit, wherein the power control circuit is connected to the potential distribution circuit, The potential distribution circuit is connected to the solenoid valve circuit. In a possible implementation of the present invention, there may be two concave chassis. The power control circuit includes a start button SB1, a power relay KM1 and a switch KM1. The potential distribution circuit includes The rotary switches SA1-1 and SA2-1 correspond to two concave chassis respectively, and the description is given by taking the control of one of the concave chassis by the rotary switch SA1-1 as an example. The specific control method includes: closing the electric brake switch QF1 and QF2, and Press the start button SB1 of the power control circuit, so that the power relay KM1 is closed, and the corresponding switch KM1 is closed, thereby turning on the power circuit. The power supply provides AC voltage and converts the AC voltage to DC voltage through the voltage converters GV1 and GV2 respectively. , the DC voltage converted by the voltage converter GV1 is distributed to the potential distribution circuit. The potential distribution circuit divides the rotation speed into high speed gear, medium speed gear and low speed gear, and divides the rotation direction into clockwise direction and counterclockwise direction. Specifically It can be controlled by the size and direction of the distributed DC voltage. It should be noted that the high-speed gear, medium-speed gear and low-speed gear correspond to their respective speed adjustment branches, and the speed adjustment branch corresponding to the low-speed gear includes normally closed contacts KA1 and KA2, the speed adjustment branch corresponding to the medium speed gear includes the normally open contact KA1, and the speed adjustment branch corresponding to the high speed gear includes the normally open contact KA2. The control of different conversion directions can be controlled by turning the switches SA1-1 and SA2- 1 Control the two concave chassis. Similarly, controlling the other concave chassis through SA2-1 is the same as SA1-1, so it will not be described again. Specifically, two concave chassis can be controlled by turning the rotary switch SA1-1. The rotation direction of the concave chassis, when turning SA1-1 to connect the circuit corresponding to the first direction (including the speed adjustment branch 1, the speed adjustment branch 2 and the speed adjustment branch 3), because the speed adjustment branch 3 includes a normally closed Contacts KA1 and KA2, and the rate adjustment branch 1 and the rate adjustment branch 2 include normally open contacts, therefore, when turning SA1-1 to connect the corresponding circuit in the first direction, the rate adjustment branch 3 ( i.e. low gear), similarly, when turning SA1-1 to switch on the circuit corresponding to the second direction (including the speed adjustment branch 4, the speed adjustment branch 5 and the speed adjustment branch 6), since the speed adjustment branch 4 includes the normal The closed contacts KA1 and KA2, while the rate adjustment branch 5 and the rate adjustment branch 6 include normally open contacts, therefore, when the circuit corresponding to the second direction is turned on by turning SA1-1, the rate adjustment branch 4 is turned on (i.e. low gear); in this way, when the concave chassis is turned on, it will be rotated at low gear by default, so as to prevent safety accidents caused by excessive speed. After connecting the circuit corresponding to the first direction or the second direction, the potential distribution circuit sends a rotation signal to the solenoid valve circuit, which The rotation of the concave chassis is controlled according to the rotation signal.

It should be noted that, for the rotation speed of the low gear, the opening of the solenoid valve can be one-third of the total opening, so that the concave chassis rotates at a low speed. Correspondingly, for the rotation speed of the middle gear, The opening of the solenoid valve can be in the state of two-thirds of the total opening, so that the concave bottom frame rotates at a medium speed, and for the rotation speed of the high gear, the opening of the solenoid valve can be in the state of the total opening, so To make the concave bottom frame rotate at high speed, of course, the corresponding relationship between the different speed gears and the opening of the solenoid valve is just an example, and the present invention is not limited to this.

The circuit shown in Figure 2 also provides a rotation rate adjustment circuit for adjusting the rotation rate. As shown in Figure 2, the rotation rate adjustment circuit includes adjustment switches SA1-2 and SA2-2, which correspond to two concave chassis respectively , the rotation rate adjustment circuit also includes adjustment relays KA1 and KA2, the adjustment relays KA1 and KA2 relays are used to adjust the rotation rate to medium-speed gear and high-speed gear, for example, through SA1-1 to switch on the branch where the adjustment relay KA1 is located When the circuit is connected, the rate adjustment branch 2 in the potential distribution circuit is connected, and the rate adjustment branch 1 and the rate adjustment branch 3 are disconnected; when the branch where the adjustment relay KA2 is located is connected through SA2-1, the potential The rate adjustment branch 1 in the distribution circuit is connected, and the rate adjustment branch 2 and the rate adjustment branch 3 are disconnected. Take the connection at SA1-1 and the adjustment of SA2-1 as an example to illustrate. When passing When SA2-1 is connected to the adjustment relay KA1 (corresponding to the adjustment of the medium speed gear), the adjustment relay KA1 is closed. At this time, the normally closed contacts KA1 and KA2 in the speed adjustment branch 3 are disconnected, and the speed adjustment branch 2 The normally open contact KA2 is closed, so that the speed adjustment branch 2 is connected, and the rotation speed is adjusted from the low speed gear to the middle speed gear; At this time, the normally closed contacts KA1 and KA2 in the speed adjustment branch 3 are disconnected, and the normally open contact KA1 in the speed adjustment branch 1 is closed, so that the speed adjustment branch 1 is connected, and the rotation speed is changed from low speed to gear to high gear.

It should be noted that, the present invention can also be realized by a PLC (Programmable Logic Controller, Programmable Logic Controller) controller.

Figure 3 is a schematic structural diagram of the ECEP 2024 controller. As shown in Figure 3, after the ECEP 2024 controller is powered on and self-inspected, the DI contact of the XM3. There is an input signal at the point, and the ECEP2024 controller performs control according to the process shown in Figure 2. It should be noted that the ECEP 2024 controller power supply works and self-checks, and then performs fault detection. The phase loss detection is carried out by the phase loss detection element KZ2. In the case of a phase loss of the three-phase power supply, KZ2 controls its normally open contact KZ2-1 not to close, so that the DI contact of XM1.20 of the ECEP 2024 controller has no input Signal, the control circuit of the hydraulic pump motor cannot be started by electricity, which plays the role of phase loss protection. Under the condition that the three-phase power supply of the hydraulic pump motor is not lacking in phase, the control circuit of the hydraulic pump motor can be connected smoothly. At this time, the phase sequence detection element KZ1 is used to detect whether the phase sequence of the three-phase power supply of the hydraulic pump motor is correct. When the phase sequence is clockwise, the normally open contact KZ1-1 of the phase sequence detection relay KZ1 is closed, and the phase sequence is counterclockwise. , it is not closed, so the DI contact signal of XM1.19 of the ECEP 2024 controller has two states. After judging by the program, the coils of the relay KA3 or KA4 are respectively controlled to be energized and closed.
