Hydraulic control lifting type device for traction fault vehicle

Abstract

The invention discloses a hydraulic control lifting type device for a traction fault vehicle. The device is characterized in that a chassis is composed of a U-shaped frame and a trailer bottom plate,a plurality of hydraulic oil cylinders are mounted on a trailer guardrail above the U-shaped frame through mounting arms, a small crane and a hydraulic control mechanism are fixedly mounted at a frontend of the U-shaped frame, a hydraulic oil cylinder control system of the remote control hydraulic control mechanism drives a hydraulic oil cylinder to lower the trailer bottom plate to the ground, asmall crane hydraulic control system controls the small crane to put down a lifting hook to hook a steel wire rope on front wheels of a story car, a hook and a front part of an accident car are lifted, a telescopic arm of the small crane retracts, after the accident car is pulled to the trailer bottom plate, the trailer bottom plate rises to an original position to facilitate conveying, the accident automobile can be detached through reverse operation. The device is advantaged in that the trailer chassis rises and falls to change the height, loading and unloading are convenient, the structureis simple and compact, production, manufacturing, installation, use and operation are convenient, cost is low, a trailer guardrail can be used for limiting and fixing an accident automobile, inclination or falling in the conveying process is prevented, secondary accidents caused by secondary collision are avoided, and the conveying process is stable and reliable.

Description

technical field [0001] The invention relates to a hydraulically controlled lifting device for towing a faulty vehicle in the technology of transportation equipment in the road traffic industry. Background technique [0002] With the rapid development of the social economy, the number of domestic automobiles has increased significantly, ranking second in the world; and with the increase in the number of automobiles, the number of traffic accidents during the operation of automobiles has also increased significantly. It will also be unable to drive normally due to failure. The accident vehicle or faulty vehicle needs to be towed, loaded and transported to the vehicle maintenance point or accident treatment center by a special trailer. The chassis of the traditional trailer has a certain height from the ground. Lifting, towing It is inconvenient to operate and difficult to load and unload; it is large and heavy, inconvenient to operate during manufacturing and installation, and...
