Technical Field

[0001] The utility model belongs to the technical field of dust covers, and particularly relates to a dust cover for an aluminum rail hoist trolley. Background Art

[0002] Since a large number of fine particles are generated when an ordinary aluminum rail hoist trolley is running, it cannot meet the cleanliness requirements of special workshops in industries such as the high-precision electronics industry, the food industry, and the aviation industry.

[0003] Generally, a crane mainly consists of a slide rail, a moving trolley, and an electric hoist. During the use of the crane, impurities such as dust and iron filings are easily generated when the wire rope of the electric hoist stretches and retracts, which affects the environment in the clean room. However, in the prior art, there is no good dust prevention when the wire rope stretches and retracts, and it is also rather troublesome to install a dust cover.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a dust cover for an aluminum rail hoist trolley.

[0006] To achieve the above purpose, the utility model provides a dust cover for an aluminum rail hoist trolley, which includes a first mounting plate. A fixing member is provided at the bottom of the first mounting plate. A clamping block is clamped at the bottom of the fixing member. A fixing assembly is arranged inside the clamping block. An installation frame is installed at the bottom of the clamping block. A dust cover body is fixedly connected to the bottom of the installation frame. A dragging assembly is provided at the bottom of the dust cover body;

[0007] The fixing assembly includes two second installation grooves opened inside the clamping block. One side of the two second installation grooves facing each other is provided with a telescopic rod. A return spring is sleeved outside the telescopic rod. A fixing block is installed at the end of the telescopic rod. One side of the outside of the fixing block is slidably connected to the inside of the second installation groove.

[0008] In one example, the dragging assembly includes a second mounting plate fixedly installed at the bottom of the dust cover body. A hook is fixedly sleeved at the center inside the second mounting plate. A baffle is rotatably connected to the outside of the hook. A spring is arranged between the baffle and the hook. A connecting block is installed at the top of the hook.

[0009] In one example, a threaded hole is opened inside the clamping block. A bolt is threadedly sleeved inside the threaded hole. The bottom of the bolt contacts the fixing block.

[0010] In one example, a limiting hole opposite to the bolt is provided on the outside of the fixing block.

[0011] In one example, a first mounting groove is formed at the center of the clamping block, the fixing member is inserted into the first mounting groove, and limiting grooves adapted to the fixing blocks are formed on both sides of the fixing member.

[0012] In one example, the threaded hole communicates with the second mounting groove, and a through hole is formed at the center of the first mounting plate.

[0013] In one example, a sliding groove is formed inside the second mounting groove, a sliding block is connected to one side of the fixing block close to the sliding groove, and the sliding groove is slidably connected to the sliding block.

[0014] The dust cover of the aluminum rail hoist trolley proposed by the present utility model can bring the following beneficial effects:

[0015] 1. When the fixing block contacts the inside of the limiting groove, the reaction force of the return spring causes the telescopic rod to drive the fixing block to approach the inside of the limiting groove, and then the limiting groove is fixed by the fixing block, thereby completing the insertion between the fixing member and the clamping block. Then, the bottom of the bolt contacts the limiting hole through the bolt and the threaded hole, further increasing the stability when the fixing block contacts the limiting groove and making the installation more convenient.

[0016] 2. When in use, the steel wire rope and the hook selected should be made of stainless steel that is not likely to generate particles. The external steel wire rope is fixedly connected to the connecting block through the through hole at the center of the first mounting plate. The dust cover body is a bellows-type dust cover, and the dust cover body can rise and fall with the lifting of the hook, so as to avoid the leakage of dust, iron filings and other impurities when the ropes of the hoist trolley telescopic during the use of the crane, and it is not easy to affect the environment in the workshop, and avoid dust from contaminating other workpieces or products in the workshop.

Specific embodiments

[0025] As Figures 1 to 5 shown, the embodiment of the present utility model provides a dust-proof cover for an aluminum rail hoist trolley, which includes a first installation plate 4. A fixing part 7 is provided at the bottom of the first installation plate 4. A clamping block 12 is clamped at the bottom of the fixing part 7. A fixing component is provided inside the clamping block 12. An installation frame 2 is installed at the bottom of the clamping block 12. The bottom of the installation frame 2 is fixedly connected to a dust-proof cover body 6. A dragging component is provided at the bottom of the dust-proof cover body 6;

[0026] The fixing component includes two second installation grooves 13 opened inside the clamping block 12. Telescopic rods 14 are installed on opposite sides of the two second installation grooves 13. A reset spring 15 is sleeved outside the telescopic rods 14. Fixing blocks 16 are installed at the ends of the telescopic rods 14. One side of the outside of the fixing block 16 is slidably connected to the inside of the second installation groove 13.

[0027] As Figure 1 and Figure 5 shown, the dragging component includes a second installation plate 5 fixedly installed at the bottom of the dust-proof cover body 6. A hook 8 is fixedly sleeved at the center inside the second installation plate 5. A baffle 10 is rotatably connected to the outside of the hook 8. A spring 9 is provided between the baffle 10 and the hook 8. A connecting block 11 is installed at the top of the hook 8. Under the elastic action of the spring 9, when the hook 8 moves an object, it is not easy to make the object deviate.

[0028] As Figure 4 shown, a threaded hole 21 is opened inside the clamping block 12. A bolt 20 is threadedly sleeved inside the threaded hole 21. The bottom of the bolt 20 contacts the fixing block 16. The bolt 20 plays a role in limiting the fixing block 16 to prevent the fixing block 16 from shifting.

[0029] As Figure 4As shown, a limiting hole 3 opposite to the bolt 20 is provided outside the fixing block 16, so that the bolt 20 further fixes the limiting hole 3 on the fixing block 16, thereby increasing the stability when the fixing block 16 is fixed to the limiting groove 17.

[0030] As Figure 4 shown, a first installation groove 1 is provided at the center of the clamping block 12. The fixing member 7 is inserted into the first installation groove 1. Limiting grooves 17 that fit with the fixing block 16 are provided on both sides of the fixing member 7. The reaction force of the return spring 15 causes the telescopic rod 14 to drive the fixing block 16 to approach the inside of the limiting groove 17, and then the limiting groove 17 is fixed by the fixing block 16.

[0031] As Figure 3 and Figure 4 shown, the threaded hole 21 communicates with the second installation groove 13. A through hole is provided at the center of the first installation plate 4. The external steel wire rope is fixedly connected to the connecting block 11 through the through hole at the center of the first installation plate 4.

[0032] As Figure 4 shown, a sliding groove 19 is provided inside the second installation groove 13. A sliding block 18 is connected to one side of the fixing block 16 close to the sliding groove 19. The sliding groove 19 is slidably connected to the sliding block 18, thereby ensuring the stability of the movement path of the fixing block 16.

[0033] Working principle:

[0034] By inserting the clamping block 12 into the fixing member 7 at the bottom of the first installation plate 4, during the insertion process, the fixing member 7 and the fixing block 16 are squeezed. During the squeezing, the return spring 15 drives the telescopic rod 14 to contract synchronously. During the contraction process, the fixing block 16 synchronously approaches the side of the return spring 15. During the approaching process, the fixing block 16 slides through the sliding block 18 and the sliding groove 19, thereby ensuring the stability of the movement path of the fixing block 16. When the fixing block 16 contacts the inside of the limiting groove 17, the reaction force of the return spring 15 causes the telescopic rod 14 to drive the fixing block 16 to approach the inside of the limiting groove 17, and then the limiting groove 17 is fixed by the fixing block 16, thus completing the insertion between the fixing member 7 and the clamping block 12. Then, the bottom of the bolt 20 contacts the limiting hole 3 through the bolt 20 and the threaded hole 21, further increasing the stability when the fixing block 16 contacts the limiting groove 17. During use, the selected steel wire rope and the hook 8 should both be made of 306 stainless steel that is not prone to generating particles. The external steel wire rope is fixedly connected to the connecting block 11 through the through hole at the center of the first installation plate 4. The dust cover body 6 is a bellows-type dust cover. The dust cover body 6 can rise and fall with the lifting of the hook 8, so as to avoid the leakage of dust, iron filings and other impurities when the rope of the hoist trolley extends and retracts during the use of the crane, and it is not easy to affect the environment in the workshop, and avoid dust from contaminating other workpieces or products in the workshop.
