A special vehicle for obstacle clearance and rescue

Abstract

The invention discloses a special vehicle for obstacle clearance and rescue, comprising a vehicle chassis, a front boom assembly installed on the vehicle chassis, a front boom assembly lifting hydraulic cylinder, and a front boom assembly lifting hydraulic cylinder installed under the front boom. A rear boom assembly lifting hydraulic cylinder is provided, the rear boom assembly lifting hydrauliccylinder being installed under the rear boom assembly. A lift hydraulic cylinder control valve, a hydraulic pump, a hydraulic oil tank, a hydraulic pipe and that like of a boom assembly are also installed on the chassis of the vehicle, the hydraulic pump is driven by a power take-off device on the chassis of the vehicle, and the lifting hydraulic cylinder of the boom assembly, the control valve ofthe lifting hydraulic cylinder of the boom assembly, the hydraulic pump and the hydraulic oil tank are connected by the hydraulic pipe. The vehicle chassis can have a front and a rear cab, and can bedriven in two directions. The obstacle removal and rescue vehicle of the invention can realize two-way obstacle removal and rescue operation, and is suitable for the occasions where the road or the operation space is narrow, and the vehicle is inconvenient to turn around, or cannot turn around.

Description

technical field The invention relates to a special vehicle, in particular to a special vehicle for obstacle removal and rescue. Background technique Faults and accidents are unavoidable when vehicles are running on the road. When such a situation occurs, a wrecking rescue vehicle is required to drag the faulty vehicle or accident vehicle away from the scene in time to ensure the smooth flow of the road. Most of the special vehicles currently used for obstacle removal and rescue are modified and manufactured by adding various devices on the basis of the second-class chassis of the automobile. The first edition of "Special Vehicle Design" published by People's Communications Publishing House in January 2007, in which Section 12.3 of Chapter 12 introduces and describes the wrecker. The structure of a wrecker is that a boom assembly, a push rail, a hydraulic winch, a multi-way reversing valve, etc. are added on the basis of the second-class chassis of the automobile. Another...

AI Technical Summary

Problems solved by technology

The obstacle removal vehicles of the above two structures have a common disadvantage, that is, only one end of the vehicle is provided with a towing traction device. Then reverse the vehicle to approach the towed vehicle for work, or make a U-turn and then reverse the vehicle so that the wrecking rescue vehicle approaches the towed vehicle for hauling and towing operations

If the work site is restricted by conditions, the obstacle removal and rescue vehicle cannot pass the towed vehicle and it is difficult or impossible to turn around, which will increase the difficulty of the obstacle removal and rescue operation and prolong the operation time, especially on elevated roads, viaducts, and tunnels. This shortcoming is even more obvious in places such as caverns, caves, and other places where the working space is narrow.
