Shear lifting mechanism type trailer

Abstract

The invention discloses a shear lifting mechanism type trailer. A plurality of installing bases on trailer guardrails on the two sides of a trailer frame of a trailer chassis are connected with a trailer bottom plate through shear fork type jacking mechanisms, a hydraulic cylinder control system of a remote control hydraulic control mechanism drives the shear fork type ejecting mechanisms to expand, the trailer bottom plate is lowered to the ground, a small crane hydraulic control system controls a small crane to put down a lifting hook for hooking up a steel wire rope of front wheels of an accident vehicle and to lift up the lifting hook and the front portion of the accident vehicle, a small crane telescopic arm retracts and pulls the accident vehicle onto the trailer bottom plate, and the shear fork type ejecting mechanism then retracts and lifts the trailer bottom plate up to an original position; and through reverse operation, the accident vehicle can be detached; the shear fork type ejecting mechanism stably performs lifting, the accident vehicle can be kept balanced all the time in the lifting, traction and transportation process, the trailer guardrails can also be used for limiting and fixing the accident vehicle and preventing the accident vehicle from inclining or disengaging in the transportation process, so that the secondary accident caused by secondary collision isavoided, stability and reliability are realized in the transportation process, the structure is simple and compact, manufacturing, installation and use and operation are convenient, and cost is low.

Description

technical field [0001] The invention relates to a scissor mechanism type trailer in the technology of transportation equipment in the road traffic industry. Background technique [0002] When the vehicle cannot drive actively due to accidents, such as tire damage, vehicle failure, or accidents, it usually needs to be towed by other vehicles, loaded and transported to the maintenance factory or accident processing center for maintenance and treatment. The traditional trailer uses a cargo box. Loading and transporting the accident car is bulky and heavy. It is inconvenient to manufacture, install, and load the accident car. It consumes a lot of raw materials and is expensive. It is difficult to load and unload, and it is difficult to maintain the balance of the accident vehicle during lifting and towing. The stability is not good, and it is easy to slip and cause secondary collisions. Contents of the invention [0003] The technical problem to be solved by the present inven...
