Semitrailer traction base for transport vehicle

Abstract

The invention discloses a semitrailer traction base for a transport vehicle. The traction base comprises a saddle, the bottom of the saddle is fixedly connected with a mounting base; a box placing plate is mounted at the bottom of the mounting base; two storage boxes are symmetrically mounted in the box placing plate; the outer end of any storage box is fixedly connected with a box handle; the outer end of the inner end of any storage box is fixedly connected with a limiting block; limiting grooves corresponding to the limiting blocks are formed in the box containing plate, reset springs are installed in the limiting grooves, four rolling grooves are formed in the sides, close to each other, of the two storage boxes at equal intervals, balls are installed in any rolling groove, and bottledbutter is arranged in any storage box. Through the arrangement of the storage mechanism, butter can be bottled and stored at the bottom of the saddle, when the traction base is smeared, the tractionbase does not need to be additionally carried, forgetting cannot be caused, and therefore it is guaranteed that the traction base can be maintained on time and is very convenient to take and use.

Description

Technical field [0001] The invention relates to the technical field of semi-trailers, in particular to a semi-trailer traction seat for transport vehicles. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and their types are divided into eleven-meter warehouse semi-trailers. Humpback transportation is a combined road and rail transportation method. The basic method is to transport the container or semi-trailer with cargo to the origin railway station by road tractor, and then transport the container or semi-trailer with cargo to the destination railway station by the railway track special vehicle. After completing the long-distance transportation and arriving at the destination railway station, the road tractor will...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a semi-trailer fifth wheel for a transport vehicle, which solves the problem that the fifth wheel needs to be frequently smeared with butter to ensure that the fifth wheel can maintain good traction performance. Carrying, it is easy to miss the situation, resulting in the failure to apply butter on time, which affects the maintenance of the traction seat, and the upper wear-resistant plate is directly fixed with the saddle by screws, and the saddle produces vibration, which is directly transmitted to the wear-resistant plate, which is easy to make the wear-resistant board loose problem
