Multifunctional heavy-duty flat-plate wrecker capable of towing three vehicles at a time

Abstract

The invention discloses a multifunctional heavy-duty flat-plate wrecker capable of towing three vehicles at a time. The wrecker comprises an automobile chassis and a wrecker top assembly assembled onthe automobile chassis, wherein the wrecker top assembly comprises a wrecker flat-plate, and a sub-frame, a double-layer frame, a flat-plate inclined oil cylinder and a flat-plate telescopic oil cylinder which are arranged below the wrecker flat-plate; the wrecker flat-plate is arranged on the sub-frame; the sub-frame is arranged on the double-layer frame; and the double-layer frame is arranged onthe automobile chassis. The wrecker top assembly also comprises a triangular turnover mechanism arranged below the tail of the sub-frame, the triangular turnover mechanism is fixedly connected with the tail of the double-layer frame and the tail of the sub-frame, one end of the sub-frame is hinged with one end of the double-layer frame through the triangular turnover mechanism, the other end of the sub-frame is connected with the other end of the double-layer frame through the flat-plate inclined oil cylinder, and the wrecker flat-plate and the sub-frame are slidably connected through the flat-plate telescopic oil cylinder and a flat guide rail. The wrecker has the advantages that the stability is good, dragging is convenient, batch production can be realized, and dragging and rescue requirements of various large, medium, heavy equipment, containers, faulted vehicles and the like can be met.

Description

technical field [0001] The invention relates to a wrecker, belonging to the field of special vehicles, in particular to a one-to-three multifunctional heavy-duty flat-bed wrecker. Background technique [0002] At present, due to its own structure, the traditional domestic flat-bed wrecker usually has low production efficiency and high transportation costs, and cannot meet the dragging requirements of transporting large and medium-sized equipment or containers of 20T and above, and cannot satisfy customers who do not send the chassis and only do it. Modular and batch production requirements for wrecker trucks. Specifically, it can be reflected from the following aspects, the shortcomings of the traditional flat wrecker: [0003] 1. The overturning mechanism is directly connected with the chassis for welding. Without the chassis, the welding of the overturning mechanism cannot be completed, and the customer needs to weld the overturning mechanism by himself. For customers who...

Problems solved by technology

[0003] 1. The overturning mechanism is directly connected with the chassis for welding. Without the chassis, the welding of the overturning mechanism cannot be completed, and the customer needs to weld the overturning mechanism by himself. For customers who are only dealers, welding is too professional and difficult, and it is impossible to realize modularization. mass production

In addition, the domestic traditional overturning mechanism usually needs to make a tail beam reinforcement, and then fix it on the chassis girder of the car through bolts. If there is no chassis overturning mechanism, it cannot be installed, and it is impossible to complete the pre-factory debugging of the wrecker top;

[0004] 2. The lifting mechanism is directly connected to the chassis, that is, the domestic flat lifting mechanism is usually installed on the outside of the chassis girder through bolts, and there is one tilting mechanism each symmetrically left and right. Since the tilting mechanism is not integral, it is performing flat lifting and lowering actions. , it cannot meet the requirements of the heavy-duty synchronous lifting platform, and the stability is poor;

[0005] 3. The bodywork of the wrecker cannot simulate the customer's on-site chassis for debugging and acceptance before leaving the factory;

[0006] 4. The flat surface is spliced ​​by stamping and forming several-shaped parts, which cannot meet the function of pulling large equipment and containers through hydraulic winches on the flat surface;

[0007] 5. The hydraulic winch is usually installed on the left side of the platform, which cannot meet the function of dragging large equipment and containers;

[0008] 6. The tail light frame is usually welded on both sides of the rear of the sub-frame, the structure is simple and ugly, and it cannot rotate with the expansion and contraction of the flat plate;

[0009] 7. The landing angle of the domestic non-folding wrecker is too large, which cannot smoothly rescue passenger cars or special vehicles with low chassis;

However, orders from foreign customers are usually placed on the basis of container loading, and the product order volume is relatively large. Based on this, it is urgent to develop a container that can realize mass production and meet the functions of transport containers, and can meet overseas markets. One-to-three multi-functional heavy-duty flatbed wreckers with the above load requirements, in order to achieve the purpose of enhancing the company's brand and market competitiveness
