Abstract

The invention provides an anti-falling device and a transport cart with the same. The anti-falling device is used for preventing a hydraulic cylinder on the transport cart from falling off. The anti-falling device comprises an anti-falling plate, the anti-falling plate is movably arranged relative to the hydraulic cylinder, and the anti-falling plate has an avoiding position and a stopping position, wherein when the anti-falling plate is located at the stop position, the anti-falling plate at least partially moves to the bottom of the hydraulic cylinder so as to stop the hydraulic cylinder from extending downwards or falling, and when the anti-falling plate is located at the receding position, the anti-falling plate moves away from the hydraulic cylinder. The anti-falling device solves theproblem that in the prior art, a hydraulic cylinder of a piggyback transport vehicle is prone to falling in the running process.

Description

technical field [0001] The invention relates to the field of transportation, in particular to an anti-off device and a transport vehicle with the same. Background technique [0002] The piggyback transport vehicle is a railway device used for road freight cars or semi-trailer road-rail combined transport. It uses related mechanisms to expand the mobile slide table. Move out with the mobile sliding table, and complete the lifting and other actions, for the semi-trailer or road truck to go up and down the concave chassis. [0003] When the concave bottom frame is turned out, the end bottom frame and the mobile slide table are required to provide a rotating slide table. When the mobile slide table provides support to the concave bottom frame, the hydraulic cylinder at the end of the mobile slide table needs to extend out of the support ground to complete the hydraulic support action. The cylinder shrinks, and when the piggyback transporter is running, the hydraulic cylinder is...
