Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation technology, specifically to an automatic locking device for high-altitude operation safety ropes. Background Technology

[0002] The automatic locking device for safety ropes used in high-altitude operations is a core component of the safety protection system for high-altitude operations. Primarily used in conjunction with the safety rope system for workers at heights, it is crucial protective equipment for preventing falls and ensuring worker safety. Its core functions are: during normal worker movement, the safety rope is allowed to extend, retract, or slide flexibly along a preset trajectory without affecting operations; when abnormal dynamics occur in the safety rope (such as a sudden fall causing rapid rope stretching or the rope's displacement speed exceeding a safety threshold), the internal braking mechanism is instantly triggered, automatically locking the safety rope and preventing further extension, thereby limiting the fall distance and avoiding or mitigating fall injuries.

[0003] However, current automatic locking devices for safety ropes used in high-altitude operations are cumbersome to install and remove, affecting work efficiency. Furthermore, when workers stop working, the safety rope cannot be actively secured and may slip slightly along the rope due to unexpected forces, posing a risk of falling. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing an automatic locking device for safety ropes used in high-altitude operations.

[0005] The specific technical solution is as follows:

[0006] An automatic locking device for a safety rope used in high-altitude operations includes: a self-locking component and a housing for high-altitude work safety, and a rope. The rope is located inside the housing, and the self-locking component is located at one end of the inner wall of the housing. A fixing frame is installed on the lower surface of the housing. The fixing frame and one side of the housing are provided with multiple identical threaded holes. A connecting plate is detachably installed on one side of the housing and the fixing frame. The connecting plate is detachably connected to the fixing frame and the surface of the housing by bolts. A first connecting rope is provided at one end of the connecting plate and one end of the upper surface of the housing. The other ends of the two first connecting ropes are respectively fixedly connected to a first connecting block and a second connecting block. The first connecting block and the second connecting block are arranged opposite to each other and together cover the surface of the rope. The two are fastened together by bolts. A hanging ring is fixedly installed on one side of the housing. The self-locking component cooperates with the rope to lock and limit the rope when it slips abnormally.

[0007] As a preferred embodiment of this utility model, the fixed frame has a hole on one side, and two fixed plates are provided on the surface of the fixed frame. A rotating shaft is rotatably installed between the two fixed plates. A limit ring is fixedly installed in the middle section of the rotating shaft. The surface of the limit ring is provided with an arc-shaped anti-slip texture that matches the outer surface of the rope. A rotating plate is fixedly connected to the other end of the rotating shaft.

[0008] As a preferred embodiment of this utility model, a positioning block is installed on one side of the surface of the fixed frame. The positioning block has a slot, and both the slot and the surface of the rotating plate have the same through holes. One end of the positioning block is provided with a second connecting rope, and the other end of the second connecting rope is connected to a fixing rod. The fixing rod can be inserted into the through holes provided on the surfaces of the positioning block and the rotating plate in sequence. By driving the rotating shaft to rotate through the rotating plate, the arc-shaped anti-slip texture provided on the surface of the limiting ring can be tightly attached to and jam the rope, thereby achieving manual locking.

[0009] As a preferred embodiment of the present invention, the self-locking component includes a semi-circular shell, which is fixedly installed on one end of the inner wall of the housing. A rotating shaft is rotatably installed on one end of the inner wall of the semi-circular shell, and an eccentric wheel is rotatably connected to one end of the rotating shaft. The inner wall of the semi-circular shell is provided with multiple ratchet grooves.

[0010] As a preferred embodiment of this utility model, a ratchet block is rotatably connected to one side edge of the eccentric wheel, and the ratchet block has multiple ratchet teeth on the side facing the ratchet groove on the inner wall of the semi-circular shell, and multiple protrusions are installed on the other side of the ratchet block facing the rope.

[0011] As a preferred embodiment of this utility model, the lateral thrust generated on the eccentric wheel when the rope slips abnormally can cause the eccentric wheel to rotate around the rotation axis, thereby driving the ratchet block to engage with the ratchet groove, and the protruding block installed on the surface fits against the rope to prevent the rope from continuing to slip.

[0012] This utility model has the following beneficial effects:

[0013] The automatic locking device for safety ropes used in high-altitude operations provided by this utility model, through the connection plate, first connecting block, and second connecting block covering the rope and then tightening it with bolts, can prevent movement and deviation along the rope, improving stability. When work is paused, the rotating plate drives the limit ring to fit against the rope, the anti-slip texture increases friction, and the insertion rod fixes the position to achieve manual locking, meeting the requirements for static stop protection. In the event of an accidental fall, the rope slides quickly, pushing the eccentric wheel to rotate, and the ratchet block's ratchet teeth engage with the ratchet groove to form a structural lock. The protruding block simultaneously presses against the rope to increase friction, and the double braking prevents the rope from sliding, effectively preventing workers from falling.

[0031] Example 1

[0032] The automatic locking device for high-altitude work safety ropes provided in this embodiment, such as Figures 1-7As shown, the system includes: a self-locking assembly 5 for high-altitude work safety, a housing 2, and a rope 1. The rope 1 is located inside the housing 2. The self-locking assembly 5 is located at one end of the inner wall of the housing 2. A fixing frame 4 is installed on the lower surface of the housing 2. The fixing frame 4 and one side of the housing 2 are provided with multiple identical threaded holes. A connecting plate 3 is detachably installed on one side of the housing 2 and the fixing frame 4. The connecting plate 3 is detachably connected to the fixing frame 4 and the surface of the housing 2 by bolts. One end of the connecting plate 3 and one end of the upper surface of the housing 2 are provided with a first connecting rope 302. The other ends of the two first connecting ropes 302 are respectively fixedly connected to a first connecting block 202 and a second connecting block 301. The first connecting block 202 and the second connecting block 301 are arranged opposite to each other and together cover the surface of the rope 1. The two are fastened together by bolts. A hanging ring 201 is fixedly installed on one side of the housing 2. The self-locking assembly 5 cooperates with the rope 1 to lock and limit the rope 1 when it slips abnormally. The fixed frame 4 has a hole on one side, and two fixed plates 401 are provided on the surface of the fixed frame 4. A rotating shaft 403 is rotatably installed between the two fixed plates 401. A limiting ring 402 is fixedly installed in the middle section of the rotating shaft 403. The surface of the limiting ring 402 is provided with an arc-shaped anti-slip texture that matches the outer surface of the rope 1. The other end of the rotating shaft 403 is fixedly connected to a rotating plate 404. A positioning block 405 is installed on one side of the surface of the fixed frame 4. The positioning block 405 has a slot. The slot and the surface of the rotating plate 404 are provided with the same through holes. A second connecting rope 406 is provided at one end of the positioning block 405. The other end of the second connecting rope 406 is connected to a locking rod 407. The locking rod 407 can be inserted into the through holes provided on the surfaces of the positioning block 405 and the rotating plate 404 in sequence. The rotating plate 404 drives the rotating shaft 403 to rotate, so that the arc-shaped anti-slip texture provided on the surface of the limiting ring 402 can tightly fit and lock the rope 1, realizing manual locking.

[0033] Through the design of the connecting plate 3, self-locking component 5, and limiting ring 402, when installing rope 1, the connecting plate 3 is removed from one side of the housing 2, and then rope 1 is placed inside the housing 2. After placement, the connecting plate 3 is installed on one side of the housing 2. Then, the first connecting block 202 and the second connecting block 301 are wrapped around rope 1 and bolted, thus avoiding the problem of movement and deviation when moving along rope 1. When pausing work for rest, the rotating plate 404 is manually rotated, which drives the rotating shaft 403 and the limiting ring 402 to rotate synchronously, so that the arc-shaped anti-slip texture on the surface of the limiting ring 402 fits against the outer surface of rope 1 until sufficient friction is formed between the anti-slip texture and rope 1. The insertion rod 407 is inserted into the through hole of the positioning block 405 and the rotating plate 404 to fix the position of the rotating plate 404, realizing the manual locking of rope 1. This can meet the safety protection needs of workers when stationary. In case of an accident, the self-locking component 5 can automatically lock, providing dynamic fall protection.

[0034] Example 2

[0035] The automatic locking device for high-altitude work safety ropes provided in this embodiment, such as Figures 5-7 As shown, the self-locking assembly 5 includes a semi-circular shell 501, which is fixedly installed on one end of the inner wall of the housing 2. A rotating shaft 505 is rotatably installed on one end of the inner wall of the semi-circular shell 501, and an eccentric wheel 506 is rotatably connected to one end of the rotating shaft 505. The inner wall of the semi-circular shell 501 is provided with multiple ratchet grooves 502. A ratchet block 503 is rotatably connected to one edge of the eccentric wheel 506. The ratchet block 503 has multiple ratchet teeth on the side facing the ratchet groove 502 on the inner wall of the semi-circular shell 501, and multiple protrusions 504 are installed on the other side of the ratchet block 503 facing the rope 1. When the rope 1 slips abnormally, the lateral thrust generated on the eccentric wheel 506 can cause the eccentric wheel 506 to rotate around the rotating shaft 505, thereby causing the ratchet teeth of the ratchet block 503 to engage in the ratchet groove 502, and the protrusions 504 installed on the surface to fit against the rope 1, preventing the rope 1 from continuing to slide.

[0036] Through the design of the semi-circular shell 501, ratchet block 503, protruding block 504, and eccentric wheel 506, during normal operation, the rope 1 slides slowly, resulting in a small lateral thrust on the eccentric wheel 506, which does not rotate. The ratchet teeth of the ratchet block 503 separate from the ratchet groove 502, and the protruding block 504 makes slight contact with the rope 1, without affecting the normal sliding of the rope 1. When the rope 1 slides abnormally and falls rapidly, the increased lateral thrust pushes the eccentric wheel 506 to rotate around the rotation axis 505, causing the ratchet block 503 to rotate towards the inner wall of the semi-circular shell 501, so that the ratchet teeth are engaged with the ratchet groove 502 to form a structural lock. At the same time, the protruding block 504 adheres tightly to the surface of the rope 1 to increase friction, forming a mechanical hard lock and friction braking, thereby effectively preventing the rope 1 from continuing to slide and avoiding the worker from falling.

[0037] In summary, the automatic locking device for safety ropes in high-altitude operations provided in this embodiment has the following advantages: the bolt-type quick-release connection design between the connecting plate 3 and the housing 2 and the fixing frame 4 can reduce the disassembly and assembly steps and time consumption, thereby improving work efficiency; and the limit ring 403 tightly fits and locks the rope 1 to avoid the risk of slipping and falling due to accidental force.

[0038] When using the rope 1, remove the connecting plate 3 from one side of the housing 2, then place the rope 1 inside the housing 2. After placement, install the connecting plate 3 onto one side of the housing 2. Then, wrap the first connecting block 202 and the second connecting block 301 around the rope 1 and tighten the bolts to prevent movement or offset along the rope 1. When pausing work, manually rotate the rotating plate 404 to drive the rotating shaft 403 and the limiting ring 402 to rotate synchronously, so that the arc-shaped anti-slip texture on the surface of the limiting ring 402 fits against the outer surface of the rope 1 until sufficient anti-slip texture is formed between the anti-slip texture and the rope 1. With sufficient friction, the insertion rod 407 is inserted into the through hole of the positioning block 405 and the rotating plate 404 to fix the position of the rotating plate 404, thus achieving manual locking of the rope 1. When the rope 1 slips abnormally and falls rapidly, the increased lateral thrust pushes the eccentric wheel 506 to rotate around the rotating shaft 505, causing the ratchet block 503 to rotate towards the inner wall of the semi-circular shell 501, so that the ratchet teeth are engaged in the ratchet groove 502 to form a structural lock. At the same time, the protruding block 504 is pressed against the surface of the rope 1 to increase the friction, forming a mechanical hard lock and friction braking, thereby effectively preventing the rope 1 from continuing to slip and avoiding the worker from falling.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
