Description

Technical Field

[0001] The utility model relates to the technical field of the body of special vehicles, in particular to a hoisting structure for the aluminum body of a special vehicle. Background Art

[0002] The hoisting assembly is an important component of the cab of a special vehicle, and hoisting screws are assembled thereon, which plays an important role in ensuring the smooth and safe installation of the cab of the special vehicle on the chassis. For an aluminum body, as Figures 1-3 shown: the material of the hoisting seat 333-2 is usually 45 steel which is difficult to be welded with aluminum alloy. The existing design is to weld the steel hoisting seat 333-2 with a bent steel plate 333-1 to form a steel hoisting assembly 333, and then insert this assembly into the round holes of the aluminum alloy ceiling 1 and the aluminum alloy top frame 2, and then rivet this assembly to the aluminum alloy top frame 2 with a certain number of rivets 444. Since there are gaps between the round holes of the aluminum alloy ceiling 1 and the aluminum alloy top frame 2 and the hoisting assembly 333, only by applying sealant can the sealing requirement be met. This structural solution has high requirements for the aging resistance of the sealant and the gluing operation requirements. Otherwise, it is easy to cause the glue layer to fall off, resulting in rainwater seeping into the cab from the round holes. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a hoisting structure for the aluminum body of a special vehicle. By placing the steel hoisting seat completely in the aluminum hoisting sleeve and the limiting plate, it is easy to perform full welding connection with the aluminum ceiling and the frame, avoiding the problems of high requirements for the aging resistance of the sealant and the gluing operation requirements in the traditional design scheme, and improving the sealing performance and structural reliability of the hoisting structure.

[0004] A hoisting structure for the aluminum body of a special vehicle, comprising a ceiling, a top frame, a hoisting assembly, and a lifting ring screw. The ceiling and the top frame are fixedly connected by intermittent welding, and the round hole of the ceiling and the hoisting assembly are fixedly connected by full welding. The hoisting assembly includes a hoisting sleeve, a hoisting seat, and a limiting plate. The hoisting seat is placed inside the hoisting sleeve. The square protrusion at the bottom of the hoisting seat is in limit socket connection with the square hole of the limiting plate. The limiting plate is welded to the bottom of the hoisting sleeve. The lifting ring screw is in threaded connection with the hoisting seat.

[0005] Preferably, sealant is applied at the socket connection between the hoisting seat and the limiting plate.

[0006] Preferably, the material of the top frame is 6061 aluminum alloy square tube.

[0007] Preferably, the material of the hoisting sleeve is 6061 aluminum alloy.

[0008] Preferably, the material of the limiting plate is 6061 aluminum alloy

[0009] Preferably, the material of the hoisting seat is 45 steel.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Good rainproof sealing performance and easy to implement. By completely placing the steel lifting seat in the aluminum lifting sleeve and the limiting plate, it is easy to perform full welding connection with the aluminum ceiling and the skeleton. Compared with the traditional design of applying sealant, the solution of the present utility model improves the sealing performance and processability of the lifting structure.

[0012] 2. High reliability. In terms of strength, the lifting sleeve of the solution of the present utility model is fully welded to the upper end face and the lower end face of the top skeleton. Compared with the traditional design where the lifting component is only riveted to the lower part of the top skeleton, the reliability of the lifting structure is improved.

[0020] The present method will be further described in combination with the drawings and embodiments. Although the description is clear and complete, it is obvious that the described embodiments are only a part of the embodiments of the present method, rather than all the embodiments. Based on the embodiments in the present method, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present method.

[0021] Such as Figure 4A hoisting structure for an aluminum body of a special vehicle as shown in FIGS. 1-6 includes a ceiling 1, a top frame 2, a hoisting assembly 3 and a lifting eye screw 4. The material of the ceiling 1 is 5052 aluminum plate, and the material of the top frame 2 is 6061 aluminum alloy square tube. The hoisting assembly 3 consists of a hoisting sleeve 3-1, a hoisting seat 3-2 and a limiting plate 3-3. The materials of the hoisting sleeve 3-1 and the limiting plate 3-3 are 6061 aluminum alloy, and the material of the hoisting seat 3-2 is 45 steel. The hoisting seat 3-2 is placed inside the hoisting sleeve 3-1, and the bottom is welded to the hoisting sleeve 3-1 by the limiting plate 3-3. The lifting eye screw 4 is threadedly connected to the hoisting seat 3-2. The square protrusion at the bottom of the hoisting seat 3-2 is sleeved in the square hole of the limiting plate 3-3 (sealant is applied at the sleeved part) for limiting to prevent the hoisting seat 3-2 from rotating when the lifting eye screw 4 is screwed. The ceiling 1 and the top frame 2 are fixedly connected by intermittent welding, and the round hole of the ceiling 1 and the hoisting assembly 3 are fixedly connected by full welding, which not only plays a waterproof role but also improves the structural strength of the cab hoisting assembly.

[0022] The specific steps are as follows: First, insert the hoisting assembly into the round hole of the top frame, and then fully weld the hoisting assembly to the upper and lower end faces of the top frame respectively; then install the ceiling on the top frame. Intermittent welding is used between the ceiling and the top frame, and full welding is used between the round hole of the ceiling and the hoisting assembly to ensure no water leakage here.
