DETAILED DESCRIPTION
[0016] The utility model is described in detail below with reference to the accompanying drawings:
[0017] like Figure 1 and 2As shown, a climbing frame compression spring protection device includes a hanger 1, which is a conventional structure in an existing climbing frame. The hanger 1 is used to fix a connection chain and an electric hoist so that the frame of the climbing frame can be pulled up or lowered by the electric hoist and the chain. A horizontally arranged support plate 2 is installed on the hanger 1, and a first through hole 3 is provided on the support plate 2. A vertically arranged adjusting screw rod 4 is provided in the first through hole 3. The adjusting screw rod 4 can move up and down in the first through hole 3 in a vertical direction. A horizontally arranged pressure plate 5 is provided above the support plate 2, and a pressure plate 5 is provided on the pressure plate 5. A second through hole 6 is provided, and the adjusting screw rod 4 passes through the second through hole 6. A compression spring 7 is sleeved on the adjusting screw rod 4, and the compression spring 7 is located between the support plate 2 and the pressure plate 5. A nut 8 is sleeved on the adjusting screw rod 4, and the nut 8 is located on the upper side of the pressure plate 5. The adjusting screw rod 4 can transfer the tension to the pressure plate 5 through the nut 8, so that the pressure plate 5 moves downward to apply pressure to the compression spring 7, and compresses the compression spring 7. The bottom end of the adjusting screw rod 4 is connected to a chain 9, and an electric hoist is provided at the bottom end of the chain 9. The chain 9 and the electric hoist adopt the conventional setting method of the existing climbing frame, and the electric hoist is used. The reed and chain 9 pull the frame of the climbing frame to move, and a protective box 10 with an open bottom structure is provided on the support plate 2. The protective box 10 is sleeved on the adjusting screw rod 4 and the compression spring 7 is located inside the protective box 10. The protective box 10 can protect the compression spring 7 on the adjusting screw rod 4, which can effectively prevent the leaked cement from falling on the compression spring 7 during cement pouring, and can also prevent the compression spring 7 from rusting due to rain falling on the compression spring 7 when it rains. In order to fix the protective box 10, a first screw hole 11 is provided on the side wall of the protective box 10, and a first screw hole 11 is provided inside the first screw hole 11. Nail 12, the inner end of the first screw 12 is provided with a first clamping plate 13, the first clamping plate 13 abuts against the edge of the pressure plate 5, and at the same time, the side wall of the protective box 10 away from the first screw hole 11 is provided with a second screw hole 14, and the second screw hole 14 is provided with a second screw 15, and the inner end of the second screw 15 is provided with a second clamping plate 16, the second clamping plate 16 abuts against the edge of the pressure plate 5, the protective box 10 is supported on the pressure plate 5 by the first clamping plate 13 and the second clamping plate 16, and at the same time, it is convenient to remove the protective box 10 to repair or replace the compression spring 7.
[0018] The bottom edge of the protection box 10 is provided with an inclined folding edge 17, which can increase the protection area, and can protect the chain 9 connected to the bottom end of the adjusting screw rod 4 and the electric hoist arranged on the chain 9.
[0019] In order to facilitate installation and removal of the protection box 10 , a handle 18 is provided on the top of the protection box 10 .
[0020] The usage of the utility model is as follows:
[0021] When in use, it is only necessary to put the protective box 10 on the adjusting screw rod 4 from top to bottom, and then tighten the first screw 12 and the second screw 15, so that the first clamping plate 13 and the second clamping plate 16 are against the edge of the pressure plate 5 to support the protective box 10 on the pressure plate 5 to complete the installation of the protective box 10. When the concrete pouring operation is carried out, if concrete leakage occurs, the leaked concrete can be blocked by the protective box 10, effectively preventing the concrete from sticking to the compression spring 7 and damaging the compression spring 7. At the same time, the folded edge 17 can also protect the chain 9 and the electric hoist, effectively preventing the leaked concrete from falling on the chain 9. When the adjusting screw rod 4 needs to be adjusted or the compression spring 7 needs to be repaired, it is only necessary to loosen the first screw 12 and the second screw 15 to remove the protective box 10, and then perform the corresponding operation, which is convenient and quick.
[0022] In addition, when the compression spring 7 breaks accidentally, the splashes generated are confined in the sealed space in the protection box 10 to prevent injuries.
