DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the implementation mode and the accompanying drawings. Here, the schematic implementation mode of the utility model and its description are used to explain the utility model, but are not used as a limitation of the utility model.

[0016] Reference Figure 1 , Figure 2 and Figure 3 A detachable installation rope fixing device includes a chassis 1 and a column 2. The chassis 1 is fixedly connected to the bottom of the column 2. A clamping assembly 3 is provided in the chassis 1. The clamping assembly 3 can clamp the chassis 1 and the steel beam. A driving assembly 4 is provided in the chassis 1 to drive the clamping assembly 3 to move. The driving assembly 4 drives the clamping assembly 3 to clamp the steel beam.

[0017] The driving assembly 4 includes a driving gear 41, a central shaft 42 is fixed at the center of the driving gear 41, the column 2 is hollow, the central shaft 42 passes through the column 2, and the top of the central shaft 42 is higher than the column 2, and a handle 43 is fixedly connected to the top of the central shaft 42.

[0018] A plurality of safety rope buckles 21 are fixed on the outer wall of the column 2, and the safety rope buckles 21 are used to tie the wire rope. The clamping assembly 3 includes a first telescopic disc 31 and a second telescopic disc 32, and a receiving chamber 11 is provided inside the chassis 1. The driving gear 41 is located at the center of the receiving chamber 11. A rack 311 is fixed on the first telescopic disc 31 and the second telescopic disc 32. The rack 311 of the first telescopic disc 31 is located on one side of the driving gear 41, and the second telescopic rack 311 is located on the other side of the driving gear 41. A claw 312 is fixed on the ends of the first telescopic disc 31 and the second telescopic disc 32 that are away from each other, and a part of the claw 312 extends out of the chassis 1.

[0019] When the driving gear 41 rotates, it can simultaneously drive the racks 311 on the first telescopic disc 31 and the second telescopic disc 32 to move, so that the first telescopic disc 31 and the second telescopic disc 32 are moved closer to or farther from each other, thereby making the claws 312 on the first telescopic disc 31 and the second telescopic disc 32 clamp the steel beam.

[0020] A plurality of slots 22 are provided on the top side wall of the column 2, and the plurality of slots 22 are evenly arranged along the circumferential direction of the column 2. A block 421 is fixed on the circumferential wall of the central axis 42, and four blocks 421 are evenly arranged along the circumferential wall of the central axis 42. The number of the slots 22 is a multiple of the number of blocks 421, and can be 12 or 16.

[0021] The thickness of the driving gear 41 is smaller than that of the rack 311. When the driving gear 41 needs to be rotated, the handle 43 is lifted to remove the clamping block 421 from the original clamping slot 22, and the handle 43 is rotated to make the driving gear 41 drive the rack 311 and the first and second telescopic disks 31 and 32 to move, so that the first and second telescopic disks 31 and 32 clamp the steel beam. Then, the handle 43 is pushed downward to insert the clamping block 421 into the corresponding clamping slot 22, so that the driving gear 41 is fixed.

[0022] Reinforcement plates 12 are fixed to both sides of the bottom shell, and the claws 312 pass through the reinforcement plates 12 , thereby increasing the stability of the claws 312 .

[0023] The implementation principle of the detachable installation rope fixing device of the utility model is as follows: when installing the fixing device of the utility model on the steel beam, first put the device on the steel beam, then rotate the handle 43 to open the first telescopic disc 31 and the second telescopic disc 32, so that the width of the claws 312 on the first telescopic disc 31 and the second telescopic disc 32 is greater than the width of the steel beam. Then rotate the handle 43 in the opposite direction to clamp the first telescopic disc 31 and the second telescopic disc 32, and then press the handle 43 downward to clamp the block 421 on the central shaft 42 into the corresponding slot 22, so as to achieve the effect of fixing the central shaft 42 and the driving gear 41. Finally, tie and install the wire rope.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
