Description

Technical Field

[0001] The utility model relates to an anti-falling detachable maintenance cover plate mechanism, belonging to the technical field of engineering machinery. Background Art

[0002] In order to facilitate the repair and maintenance of engineering vehicles, it is usually necessary to design a maintenance cover at the bottom of the engineering vehicle or the bottom of the engine. The maintenance cover needs to be disassembled during the repair and maintenance of the engineering vehicle, so it is required to be easy to disassemble. On the other hand, the maintenance cover located at the bottom of the engineering vehicle needs to have a certain structural strength to protect the components in the body structure. At present, in order to ensure the strength of the structure, the maintenance cover of the engineering vehicle is mostly made of iron or aluminum alloy, and a detachable structure is designed. However, the weight of the maintenance cover is heavy, and it is very inconvenient to disassemble it due to the influence of gravity. Moreover, the larger maintenance cover will cause the maintenance cover to fall during the disassembly process due to the sudden failure of the locking mechanism, posing a great threat to the safety of personnel. The same problem also exists in the assembly process. The installation of the maintenance cover becomes more difficult due to the influence of gravity, which increases the time for repair and maintenance. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned shortcomings of the prior art and provide a detachable maintenance cover mechanism that prevents falling.

[0004] The technical solution provided by the utility model is as follows: a kind of anti-falling detachable maintenance cover mechanism, which comprises a frame bottom plate and frame side plates connected at both ends of the frame bottom plate, characterized in that a maintenance cover mounting hole is provided on the frame bottom plate, a maintenance cover mounting plate is respectively connected to both sides of the frame bottom plate, and a plurality of maintenance covers are movably connected at the maintenance cover mounting holes between the two maintenance cover mounting plates by fastening bolts; the maintenance cover comprises a flat plate, an anti-falling positioning plate is symmetrically connected to the flat plate, positioning claws are provided at both ends of the anti-falling positioning plate, and positioning grooves corresponding to the positioning claws are provided on the maintenance cover mounting plate.

[0005] Furthermore, the flat plate is provided with a positioning plate threaded hole, and a bolt protection seat is provided at the positioning plate threaded hole at the lower end of the flat plate; a mounting plate threaded hole corresponding to the positioning plate threaded hole is provided on the maintenance cover mounting plate; the maintenance cover is installed on the maintenance cover mounting plate through the fastening bolts in the positioning plate threaded hole and the mounting plate threaded hole; the height of the bolt protection seat is higher than the height of the fastening bolt after installation.

[0006] Furthermore, the flat plate is provided with two elliptical transition holes.

[0007] The beneficial effect of the utility model is that when the utility model is installed, the positioning claw of the anti-falling positioning plate on the maintenance cover first passes through the positioning slot of the maintenance cover mounting plate, and then translates to the positioning plate threaded hole of the maintenance cover to align with the mounting plate threaded hole on the maintenance cover mounting plate, and then tightens the fastening bolts in sequence. The maintenance cover of the utility model is fastened with the maintenance cover mounting plate by fastening bolts, and no additional force is required to assist in preventing the maintenance cover from falling, which greatly improves the efficiency and safety of installation. The maintenance cover can effectively protect the internal components from damage and has a high structural strength. At the same time, during the disassembly process, the positioning claw of the anti-falling positioning plate can prevent the maintenance cover from falling suddenly. The anti-falling positioning plate can not only play the role of positioning and anti-falling, but also serve as a reinforcing rib plate of the flat plate, further improving the overall structural strength of the maintenance cover and improving the reliability of the maintenance cover. In order to facilitate disassembly and assembly and ensure the installation fastness of the maintenance cover, the maintenance cover can be designed as one or more pieces according to the requirements of the maintenance and maintenance port. Through the two elliptical transition holes on the flat plate of the maintenance cover, the maintenance cover can be translated to the position claw of the anti-falling positioning plate and the position slot of the maintenance cover mounting plate, and the maintenance cover can be removed downward. In this way, the unsafe factors caused by the maintenance cover falling due to gravity can be effectively eliminated during the entire disassembly process, and the position of the position slot of the maintenance cover mounting plate is the only position where the maintenance cover can be removed, which improves the efficiency of disassembly. The two elliptical transition holes on the flat plate can not only reduce the overall weight of the maintenance cover, but also serve as a force application port for moving and disassembling the maintenance cover, which is more convenient for moving, installing and disassembling the maintenance cover. At the same time, considering that the maintenance cover is located at the bottom of the vehicle body, it is often scratched, which may cause the fastening bolts to fall off. In order to ensure the reliability of the fastening of the fastening bolts, a bolt protection seat is designed. The height of the bolt protection seat should be higher than the height of the fastening bolts after installation, which can effectively avoid the engineering vehicle from scratching the fastening bolts during operation, and well protect the functional effectiveness of the mechanism. The utility model greatly improves the safety and convenience of the removal and installation of the cover, saves the time of the removal and installation of the maintenance cover, improves the structural strength, and is safe and reliable.

[0012] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0013] like Figure 1-Figure 4 As shown, a fall-proof detachable maintenance cover mechanism includes a frame bottom plate 4 and frame side plates 3 connected at both ends of the frame bottom plate 4, a maintenance cover mounting hole 5 is provided on the frame bottom plate 4, and a maintenance cover mounting plate 2 is respectively connected to both sides of the frame bottom plate 4, and a plurality of maintenance covers 1 are movably connected at the maintenance cover mounting holes 5 between the two maintenance cover mounting plates 2 through fastening bolts 6.

[0014] like Figure 3 As shown, the maintenance cover 1 includes a flat plate 12, to which an anti-falling positioning plate 11 is symmetrically connected, positioning claws 14 are provided at both ends of the anti-falling positioning plate 11, two elliptical transition holes 15 and four positioning plate threaded holes 16 are provided on the flat plate 12, and a bolt protection seat 13 is provided at the positioning plate threaded hole 16 at the lower end of the flat plate 12.

[0015] like Figure 4 As shown, the maintenance cover mounting plate 2 is provided with a positioning groove 21 corresponding to the positioning claw 14, and the maintenance cover mounting plate 2 is provided with a mounting plate threaded hole 22 corresponding to the positioning plate threaded hole 16. The maintenance cover 1 is connected to the maintenance cover mounting plate 2 through the fastening bolts 6 in the positioning plate threaded hole 16 and the mounting plate threaded hole 22. The height of the bolt protection seat 13 should be higher than the height of the fastening bolt 6 after installation, so that the engineering vehicle can be effectively prevented from being scratched by the fastening bolt 6 during operation, and the functional effectiveness of the mechanism is well protected.

[0016] During installation, the positioning claws 14 of the anti-falling positioning plate 11 on the maintenance cover 1 are first passed through the positioning slots 21 of the maintenance cover mounting plate 2, and then translated to align the positioning plate threaded holes 16 of the maintenance cover 1 with the mounting plate threaded holes 22 on the maintenance cover mounting plate 2, and then the fastening bolts 6 are tightened in sequence. Tightening the fastening bolts 6 does not require additional force to assist in preventing the maintenance cover 1 from falling, which greatly improves the efficiency and safety of installation.

[0017] During the disassembly process, the fastening bolts 6 need to be removed in sequence. After the fastening bolts 6 are removed, the maintenance cover 1 will fall due to gravity. The positioning claws 14 of the anti-falling positioning plate 11 of the maintenance cover 1 are in contact with the maintenance cover mounting plate 2 and blocked. In this way, even if the fastening bolts 6 are completely removed, the maintenance cover 1 will not fall suddenly. Through the elliptical transition hole 15 of the flat plate 12 of the maintenance cover 1, the maintenance cover 1 can be easily translated until the positioning claws 14 of the anti-falling positioning plate 11 coincide with the positioning slots 21 of the maintenance cover mounting plate 2, and the maintenance cover 1 can be removed downward. In this way, during the entire disassembly process, the unsafe factors caused by the maintenance cover 1 falling due to gravity can be effectively eliminated, and the positioning slots 21 of the maintenance cover mounting plate 2 are the only position where the maintenance cover 1 can be removed. As a translation positioning for disassembling the maintenance cover 1, the efficiency of disassembly is improved.

[0018] It should be understood that the parts not elaborated in detail in this specification belong to the prior art. The above embodiments are only descriptions of the preferred implementation methods of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit of the utility model, various modifications and improvements made by ordinary engineers and technicians in this field to the technical solution of the utility model should fall within the protection scope determined by the claims of the utility model.
