A hydraulic trailer device

Abstract

A hydraulic trailer apparatus including the front, Cars and wheels, one side of the vehicle head is provided with a vehicle compartment, Wheels are fixedly mounted at the four corners of the bottom ofthe car, the middle position of the car is provided with a mounting cavity, a hydraulic cylinder is welded in the middle position of the inner bottom wall of the mounting chamber, A horizontal plateis fixedly mounted on the piston rod of the hydraulic cylinder, the middle position of the transverse plate is provided with a groove, two-way threaded columns are rotatably installed on both sides ofthe inner wall of the groove, the two sides of the two-way threaded column are all threaded with movable plates, A support rod is fixedly connected with the top of the movable plate, a fixing block is welded on the top of the support rod, two ends of two bidirectional threaded columns close to each other are fixedly connected with mounting columns, a driving motor is fixed at the middle positionof the top of the transverse plate through locking bolts, and an output shaft of the driving motor extends to the inside of the groove. The invention has the advantages of simple structure, reasonabledesign and novel conception, improves the stability of the trailer equipment when in use, and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of trailers, in particular to hydraulic trailer equipment. Background technique [0002] A trailer is a kind of vehicle used to haul a car. It consists of a chassis, a lifting device, a lifting device, a hydraulic system, an electronic control system, a car body and a toolbox, etc. It has the functions of lifting, pulling and lifting traction. It is suitable for clearing obstacles on highways and urban roads. [0003] At present, when the trailer equipment is in use, the car is directly placed on the carriage, and the trailer is prone to shaking during transportation, which causes the car on the carriage to move back and forth. When the trailer encounters an emergency and brakes suddenly, the car on the carriage Under the action of inertia, it is easy to cause a collision between the car and the trailer compartment, which will damage and deform the car. Therefore, we propose a hydraulic trailer device to so...
