Background

When the highway and railway engineering vehicle is used for construction operation on a railway track, in order to ensure the stability in the operation process, the supporting device is required to be used for supporting the vehicle body. The existing supporting devices are fixed structures, and when the engineering truck runs on a rail, a supporting oil cylinder can extend out abnormally, so that line equipment is damaged and even accidents occur; when the engineering truck runs on a road, the road passing performance of the vehicle is influenced by the fact that the height of the support from the ground is too low.

Disclosure of Invention

The invention aims to solve the problems that the supporting device can prevent the supporting oil cylinder from extending out abnormally when the vehicle track runs and improve the road passing performance of the vehicle running on the road. The technical scheme is as follows:

the device comprises a base and a support arranged at the lower part of the base, wherein one side of the end part of the support is rotatably connected with the base, and the other side of the end part of the support is movably connected with the base through a bolt component; the base comprises a beam assembly, a bottom plate, a rotating vertical plate, a movable vertical plate and a rotating shaft, the beam assembly comprises an upper cover plate, a web plate and a lower cover plate, the upper cover plate, the web plate and the lower cover plate form a box-shaped structure, and the rotating vertical plate and the movable vertical plate are respectively and fixedly connected to the upper part of the lower cover plate at one end of the base; the support comprises an oil cylinder, a rotary inserting plate and a movable inserting plate, the rotary inserting plate and the movable inserting plate are fixedly connected to the lower portion of a flange of the oil cylinder respectively, and the rotary inserting plate is connected with the rotary vertical plate through a rotating shaft.

And a hanging plate and a hanging ring seat are arranged on the outer wall of the oil cylinder.

The bolt assembly is arranged on the outer wall of the oil cylinder and comprises a bolt, a backstop pin and a chain ring, and the bolt is connected to the hanging ring seat through the chain ring.

Compared with the prior art, the invention has the following beneficial effects:

1. during construction operation, the hydraulic support is in the support position, and the vertical force is transmitted through the base, so that the stress distribution of the bearing position is improved.

2. When the vehicle runs on the railway track, the hydraulic support is in a suspension position, and the phenomenon that line equipment is damaged or accidents are caused by the fact that the support oil cylinder extends out abnormally when the vehicle runs on the railway track is avoided.

3. When the vehicle runs on a road, the hydraulic support is in a suspension position, the ground clearance of the lower part of the vehicle is increased, and the approach angle and the departure angle of the vehicle when the vehicle runs on the road are increased.

4. The bolt assembly can quickly lock the hydraulic support at the supporting position and the hanging position, and is convenient to operate, safe and reliable.

5. The supporting structure of the invention has simple and reasonable design, improves the stability of the whole vehicle during operation and prolongs the service life.
