Description

A variable supporting device for a train bogie frame}

The present invention relates to a railway vehicle bogie frame variable support device in which a hydraulic force and a support rod are installed to build an environment in which a vertical load and a reaction force component due to vertical torsional loads and side loads are applied to a railway vehicle bogie frame. In more detail, the distance between the hydraulic pressure generator and the support rod on the ground without the need to disassemble and assemble the hydraulic force and the support rod through the variable rail beam that the interval is variable corresponding to the railway vehicle bogie frame having a variety of sizes In addition, it relates to a railway vehicle bogie frame variable support device that is easy to work by combining the bogie frame with hydraulic press and bogie frame on the ground.

In general, the safety factor of railway vehicles is largely determined by the bogie frame on which the wheels are mounted.

For this reason, the safety test of the trolley frame of such a railway vehicle is carried out at all times, and these safety tests are divided into two types, which are simple safety tests in which the safety element of the bogie frame is tested through the sound of a hammer being hit by a human being. And, it is divided into the main safety test to test the load of the bogie frame by installing in a separate test device.

The latter main safety test is a safety test after separating the bogie frame to the passenger car, wherein the bogie frame is to separate the additional devices such as wheels and suspension, and then load the bogie frame only on the test device and load test Done.

The conventional bogie frame testing apparatus installs a load cell at four points installed on the bogie frame and then places a support for supporting the bogie frame thereon and forcibly loads the hydraulic frame to the top of the bogie frame. The load cell installed in the load gauge was measured to distribute the load on the bogie frame to determine whether the bogie frame was defective.

However, this method has a disadvantage in that it is very difficult to distribute the weight load of the bogie frame weight evenly on the support.

In other words, the load cell of four points supports four places of the bogie frame. In this case, when the supported center point is wrong, the measured values of each load cell are different, so it is very difficult to find the exact support point.

Therefore, in order to find the exact support point, it is very time-consuming and safety risks have to be raised because it has to be lifted and reloaded several times.

Recently, the bogie frame was spaced from the ground, and a support structure environment was constructed to test the reaction force component due to the vertical load, the vertical torsional load and the side load imposed on the bogie frame.

However, such a support structure is a static steel beam structure, there is a problem in that the hydraulic pressure and the support rod to be assembled to the steel beam structure according to the size of the bogie frame.

In other words, in order to install the hydraulic press and the supporting rod, first, the size of the bogie frame is measured, and the maneuver must be installed on the steel beam structure in the ceiling according to the measured value, and the human being should install the hydraulic press and the supporting rod according to the measured value. There was a problem.

Therefore, instead of disassembling the hydraulic presser and the supporting rod to the steel beam according to the size of the bogie frame, it is easy to work by first arranging the gap between the hydraulic press and the supporting rod on the ground and combining the hydraulic presser and the bogie frame with the corresponding bogie frame. There is a demand for a variable support device for a railway vehicle bogie frame having a structure.

The present invention has been made in view of the above problems, the present invention is four upright beams supported on the ground when standing up; and a pair of each of which is connected in the horizontal direction to the top of the two support beams of each of the support beams And a plurality of fixed rail beams and a plurality of variable rail beams installed through connecting means in a direction intersecting the lower ends of the fixed rail beams and having moving means to move on the fixed rail beams. Each variable rail beam is to provide a railway vehicle bogie frame variable support device, characterized in that a plurality of supporting means connected to the support rod or hydraulic force is installed so that the bogie frame is spaced apart from the ground to apply a load.

According to the railway vehicle bogie frame variable support device according to the present invention, without disassembling the hydraulic pressor and the support rod to the steel beams according to the size of the bogie frame, first adjust the distance between the hydraulic pressurizer and the support rod on the ground and the corresponding bogie frame It is easy to work by combining the hydraulic force and the bogie frame.

In addition, the hydraulic press and the support rod can be installed on the bogie frame only by working on the ground, thereby preventing the risk of a safety accident.

Hereinafter, with reference to the accompanying drawings with respect to the variable support device for a railway vehicle bogie frame according to the present invention will be described in detail.
