[0003] When using the current safety rope structure, the safety rope is fixedly connected to the hook, which is hung on a solid power support. The worker connects the other end of the safety rope to his or her own safety belt. After the safety rope is connected, the worker climbs up and down the power support. The safety rope structure can provide protection if the worker slips from the power support.

[0004] When using the traditional safety rope structure, if a worker misses or slips on the power support, the safety rope will pull the worker up to prevent the worker from falling. Since the safety rope is not equipped with a buffer device, when the safety rope is suddenly straightened, the safety belt and the worker will be pulled very tight, causing skin contusion at the connection between the safety belt and the worker, which makes it inconvenient to promote the use of the safety rope structure.

[0008] Preferably, a sealing rubber ring is installed on the top of the sleeve, and the inner wall of the sealing rubber ring is movably connected to the outer wall of the vertical rod.

[0009] Preferably, the fixing device includes: two rotating cylinders, both of which are rotatably connected to the inner wall of the bottom cylinder through bearings; two slides, respectively movably connected to the inner walls of the two rotating cylinders; two threaded rods, respectively installed on the inner sides of the two slides, and both connected to the internal threads of the bottom cylinder; two clamping blocks, respectively rotatably connected to the inner sides of the two threaded rods through bearings, and both abut against the outer wall of the rope, and the outer walls of the two clamping blocks are movably connected to the inner wall of the bottom cylinder; two nuts, respectively installed on the outer walls of the two rotating cylinders;

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0022] When using a traditional safety rope structure, if a worker misses or slips on the power support, the safety rope will pull the worker up to prevent the worker from falling. However, since the safety rope has no buffer device, when the safety rope suddenly straightens, the safety strap and the worker will be pulled very tight, causing skin contusion at the connection between the safety strap and the worker, making it difficult to promote the use of the safety rope structure.

[0023] In view of this, the utility model provides a safety rope structure for power construction, in which a hook is installed on a power support, and a nut is used in conjunction with a rotating plate to completely close the hook to prevent the hook from falling off. A buffer device is used to buffer the space between the hook and the rope to prevent the rope from being straightened when the worker falls, causing contusion at the connection between the safety belt and the worker, thereby facilitating the promotion and use of the safety rope structure.

[0024] Example 1: By Figure 1 、 2 , 3 and 4 show that a safety rope structure for electric power construction includes a hook 1, a bottom cylinder 3 is provided at the bottom of the hook 1, a rope 5 is installed inside the bottom cylinder 3, a torsion spring 7 is installed inside the hook 1, a rotating plate 8 is rotatably connected to the inside of the hook 1 through a pin shaft, the outer wall of the rotating plate 8 is fixedly connected to the outer wall of the torsion spring 7, and a nut 9 is threadedly connected to the outer wall of the hook 1. The safety rope structure for electric power construction also includes: a buffer device 2, which is installed below the hook 1; a fixing device 4, which is installed inside the bottom cylinder 3; and an anti-slip device 6, which is installed on the outer wall of the bottom cylinder 3; wherein the buffer device 2 can buffer between the rope 5 and the hook 1 when the rope is tightened, the fixing device 4 fixes the rope 5, and the anti-slip device 6 can prevent the fixing device 4 from falling off when in use;

[0025] During the specific implementation, it is worth noting that the hook 1 is hung on the power support, the nut 9 is used to lock the rotating plate 8 and the hook 1 to prevent the hook 1 from falling off, the fixing device 4 is used to fix the rope 5 inside the bottom cylinder 3, the anti-falling device 6 can prevent the fixing device 4 from loosening and causing the rope 5 to fall off, and the buffer device 2 provides a buffer between the rope 5 and the hook 1;

[0026] Specifically, when using the power construction safety rope structure, push the turn plate 8 to rotate, the turn plate 8 compresses the torsion spring 7, and the turn plate 8 is no longer locked with the hook 1. Hang the hook 1 on the power bracket. After opening the turn plate 8, the torsion spring 7 in the compressed state helps the turn plate 8 to reset, and rotate the nut 9 to lock the connection between the hook 1 and the turn plate 8 to prevent the hook 1 from falling off. Fix the rope 5 to the inside of the bottom cylinder 3 through the fixing device 4, and use the anti-slip device 6 to prevent the fixing device 4 from loosening. The buffer device 2 can buffer the space between the rope 5 and the hook 1.

[0027] Example 2: By Figure 1 、 2, 3 and 4 show that the buffer device 2 includes: a vertical rod 201, mounted on the bottom of the hook 1; a horizontal plate 202, mounted below the vertical rod 201; a sleeve 203, movably connected to the outer side of the horizontal plate 202 and movably connected to the outer wall of the vertical rod 201, and the bottom of the sleeve 203 is fixedly connected to the top of the bottom cylinder 3; a first spring 204, mounted inside the sleeve 203 and tightly abutting against the top of the horizontal plate 202; wherein, when the sleeve 203 moves downward, it compresses the first spring 204, and the first spring 204 is deformed after compression, thereby providing a buffer between the rope 5 and the hook 1;

[0028] In the specific implementation process, it is worth noting that a shock-absorbing damper is provided at the connection between the horizontal plate 202 and the sleeve 203. When the sleeve 203 is subjected to a downward force, it slides on the outer wall of the horizontal plate 202. At the same time, the sleeve 203 compresses the first spring 204, and the first spring 204 is deformed after being squeezed.

[0029] Furthermore, a sealing rubber ring 10 is installed on the top of the sleeve 203, and the inner wall of the sealing rubber ring 10 is movably connected to the outer wall of the vertical rod 201;

[0030] In the specific implementation process, it is worth noting that the sealing rubber ring 10 can prevent foreign matter such as dust from entering the interior of the sleeve 203;

[0031] Specifically, on the basis of the above-mentioned embodiment 1, the rope 5 pulls the sleeve 203 to move through the bottom tube 3, and the sleeve 203 moves downward after being subjected to the force. When the sleeve 203 slides outside the cross plate 202, it compresses the first spring 204. The first spring 204 is deformed after being squeezed. Since the sleeve 203 connects the rope 5 and the hook 1 together, when the sleeve 203 moves, it can play a buffering role between the rope 5 and the hook 1, and the sealing rubber ring 10 prevents dust from entering the inside of the sleeve 203.

[0032] Example 3: By Figure 1 、 2 As can be seen from Figure 4, the fixing device 4 includes: two rotating drums 401, both of which are rotatably connected to the inner wall of the bottom drum 3 through bearings; two slide plates 402, which are movably connected to the inner walls of the two rotating drums 401; two threaded rods 403, which are respectively installed on the inner sides of the two slide plates 402 and are both connected to the internal threads of the bottom drum 3; two clamping blocks 404, which are respectively rotatably connected to the inner sides of the two threaded rods 403 through bearings and are both tightly pressed against the outer wall of the rope 5, and the outer walls of the two clamping blocks 404 are movably connected to the inner wall of the bottom drum 3; two nuts 405, which are respectively installed on the outer walls of the two rotating drums 401; wherein, when the nuts 405 rotate, they drive the slide plates 402 inside the rotating drum 401 to rotate, the slide plates 402 drive the threaded rods 403 to rotate, and the threaded rods 403 drive the clamping blocks 404 to fix the rope 5 inside the bottom drum 3;

[0033] In the specific implementation process, it is worth noting that anti-sliding blocks are provided inside the clamping block 404 and the bottom cylinder 3 to increase the friction between the clamping block 404 and the rope 5. When the rotating drum 401 rotates through the nut 405, the sliding block 402 drives the threaded rod 403 to rotate, and the threaded rod 403 drives the clamping block 404 to move. The clamping block 404 cooperates with the bottom cylinder 3 to fix the rope 5.

[0034] Specifically, on the basis of the above-mentioned embodiment 1, the staff drives the nut 405 to rotate with the help of a tool, and the nut 405 drives the rotating drum 401 to rotate, and the rotating drum 401 drives the threaded rod 403 to rotate through the slide 402. Since the clamping block 404 is restricted by the bottom drum 3, the threaded rod 403 drives the clamping block 404 to move, and the clamping block 404 cooperates with the bottom drum 3 to fix the rope 5. The rope 5 is fixed using the fixing devices 4 on both sides. When the fixing device 4 on one side is loose, the rope 5 can continue to be fixed by the fixing device 4 on the other side.

[0035] Example 4: By Figure 1 、 2 As can be seen from Figure 4, the anti-slip device 6 includes: two outer cylinders 601, both of which are installed on the outer wall of the bottom cylinder 3; two slide rods 602, which are movably connected to the inside of the two outer cylinders 601 and plugged into the outer wall of the rotating cylinder 401; two second springs 603, which are respectively installed in the inside of the two outer cylinders 601 and respectively pressed against the outer walls of the two slide rods 602; wherein, pulling the slide rod 602 compresses the second spring 603, and at the same time, the slide rod 602 is no longer plugged into the outer wall of the rotating cylinder 401, and no longer fixes the rotating cylinder 401;

[0036] In the specific implementation process, it is worth noting that when the sliding rod 602 is pulled upward, the sliding rod 602 compresses the second spring 603, and the sliding rod 602 is no longer plugged into the rotating drum 401;

[0037] Specifically, based on the above-mentioned embodiment 1, the staff pulls the slide rod 602 to move upward, the slide rod 602 compresses the second spring 603, and at the same time the slide rod 602 is no longer plugged into the rotating drum 401. After the rotating drum 401 rotates, the slide rod 602 is released, and the second spring 603 in a compressed state helps the slide rod 602 to reset, and the slide rod 602 is inserted into the hole on the outer wall of the rotating drum 401 to prevent the rotating drum 401 from rotating at will.
