AI Technical Summary
The cylinder push structure of existing flatbed wreckers leads to limited thrust distance, limited slope reduction, and single function, which cannot accommodate a variety of vehicles with lower chassis.
A sub-beam structure that can be translated by the wreck-clearing vehicle is designed, adopting a dual oil cylinder pushing system, including the main oil cylinder and the secondary oil cylinder. The sub-beam is pushed through the main oil cylinder. The sub-bottle can be individually telescopic and push the flat plate, extending the expansion distance, and a wear-resistant pad is installed between the longitudinal beam and the chute to reduce noise.
The wreck-clearing vehicle flat plate slides outward to a maximum extent under the dual push of the main and secondary oil cylinders, reduces the flat plate angle, adapts to various vehicles with lower chassis, has a wider range of use, and effectively extends the service life of the secondary beam and chute.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a dry and wet dual-purpose vacuum cleaner box structure. Background Art
[0002] A flatbed tow truck is an important rescue vehicle. In order to make it easier for the vehicle to be towed onto the flatbed, the existing flatbed tow trucks generally use a cylinder to push the flatbed backwards, and then use a lifting cylinder to lift the front end of the flatbed. This structure is conducive to reducing the slope and making it easier for the vehicle to be towed onto the flatbed. However, since only one cylinder is used for pushing, the pushing distance is limited, the slope that can be reduced is also limited, and the cylinder can only push the flatbed while pushing the sub-beam to move, and the function is limited. Summary of the invention
[0003] In order to overcome the deficiencies in the prior art, the utility model provides a sub-beam structure of a tow truck that can be translated, which comprises two longitudinal beams arranged in parallel, a cross beam is evenly arranged between the two longitudinal beams, a lifting cylinder is arranged between the vehicle chassis and the longitudinal beams, the right end of the cross beam is movably connected to the right end of the vehicle chassis, slide grooves are respectively arranged on the opposite sides of the two longitudinal beams, U-shaped sub-beams that can slide therein are arranged in the two slide grooves, reinforcing ribs are also evenly arranged on the sub-beams, sub-cylinders are symmetrically arranged on the inner side of the sub-beams, the left end of the sub-cylinders is connected to a fixing plate, the fixing plate is fixedly connected to the flat plate, a main cylinder is installed on the cross beam, and the other end of the main cylinder is connected to the sub-beam.
[0004] In order to extend the service life of the auxiliary beam and the slideway and reduce the noise when the auxiliary beam moves, a wear-resistant pad is arranged on the outer surface of the auxiliary beam in contact with the slideway.
[0005] The beneficial effects of the utility model are:
[0006] 1. In the utility model, when the main oil cylinder does not move, the auxiliary oil cylinder can be extended and retracted independently, and the flat plate can be pushed to move forward and backward, which can effectively extend the extension distance.
[0007] 2. Compared with the old model with single sub-frame structure, short telescopic distance and steep flatbed slope, this design can make the flatbed of the tow truck slide outward to a greater extent under the dual push of the main and auxiliary cylinders, so that the tow truck has a lower flatbed angle during use, adapting to various vehicles with lower chassis and having a wider range of use. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0009] Figure 1 It is a structural schematic diagram of the utility model.
[0010] Figure 2 It is a right-side structural schematic diagram of the utility model.
[0011] In the figure: longitudinal beam 1, slide 2, wear-resistant pad 3, auxiliary beam 4, reinforcing rib 6, auxiliary cylinder 7, main cylinder 8, fixing plate 9, cross beam 10. DETAILED DESCRIPTION
[0012] exist Figure 1 and Figure 2 A sub-beam structure of a tow truck that can be translated is provided, which comprises two parallel longitudinal beams 1, a cross beam 10 is evenly arranged between the two longitudinal beams 1, a lifting cylinder is arranged between the vehicle chassis and the longitudinal beams 1, the right end of the cross beam 10 is movably connected to the right end of the vehicle chassis, and slide grooves 2 are respectively arranged on the opposite sides of the two longitudinal beams 1, and U-shaped sub-beams 4 that can slide therein are arranged in the two slide grooves 2, and reinforcing ribs 6 are evenly arranged on the sub-beams 4, and sub-cylinders 7 are symmetrically arranged on the inner side of the sub-beam 4, and the left end of the sub-cylinder 7 is connected to a fixing plate 9, and the fixing plate 9 is fixedly connected to the flat plate, and a main cylinder 8 is installed on the cross beam 10, and the other end of the main cylinder 8 is connected to the sub-beam 4.
[0013] Furthermore, a wear-resistant pad 3 is provided on the outer surface of the sub-beam 4 that contacts the slide groove 2 .
[0014] When working, the main oil cylinder 8 pushes the auxiliary beam 4 to move to the right, and the flatbed moves to the right along with the auxiliary beam 4. If the moving distance is insufficient, the auxiliary oil cylinder 7 can continue to pull the flatbed to move to the right. After the flatbed moves, the lifting oil cylinder is started to lift the left end of the longitudinal beam to facilitate the vehicle to be towed onto the flatbed. This structure increases the rightward moving distance of the flatbed, which is conducive to making the flatbed have a lower slope and is convenient for various vehicles to be towed onto the flatbed.
[0015] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
