Description

Technical Field

[0001] This utility model relates to the field of safety rope technology, and more specifically, to a fall protection safety rope. Background Technology

[0002] A safety rope is an auxiliary rope used in high-altitude operations to protect workers, prevent them from falling, and improve safety.

[0003] Publication number CN220025928U discloses a fall protection safety rope, the technical solution of which includes a safety rope and an expansion bolt. The expansion bolt is set two meters above the pre-installed position of the steel waler and steel support. The safety rope is straightened and installed on the expansion bolt. The expansion bolt is set correspondingly to the steel support and is anchored in the retaining pile. Several buckles are fixed to the end of the safety rope, and the opening direction of the several buckles is facing the safety rope that is mainly subjected to force.

[0004] The above-mentioned technical solution, through the installation of expansion bolts, can effectively prevent workers from accidentally falling from heights during the erection and dismantling of steel supports when they are using safety ropes for high-altitude operations, thereby improving the safety of workers when they are working at heights.

[0005] However, when workers accidentally fall during high-altitude operations, the above-mentioned technical solution only restricts the movement of the safety rope through expansion bolts. This means that the worker will have to fall until the safety rope is exhausted before it can stop. Since the safety rope is usually quite long, the worker will be subjected to inertia after the safety rope stops moving, resulting in a large impact force and affecting the worker's safety.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fall protection safety rope, which solves the problem that when workers accidentally fall during high-altitude operations, they will be subjected to a large impact force due to inertia, which affects the safety of the workers.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fall prevention safety rope, comprising a safety rope body with a support frame, two through holes respectively opened at the top and bottom of the support frame, a winding spool rotatably connected inside the support frame, a through groove opened on the side wall of the support frame for winding the safety rope body to the winding spool and communicating with the through holes, a movable plate slidably connected inside the support frame, a plurality of limiting teeth fixedly connected to the side of the movable plate near the winding spool, and a driving component for driving the movable plate to move along the side wall of the support frame and a fixing component for fixing the support frame to an external object.

[0009] By adopting the above technical solution, when workers use the safety rope for high-altitude operations, the safety rope is looped, and then the looped part of the safety rope is inserted into the support frame along the through groove. The safety rope is then wound around the reel, with the safety rope positioned at the through hole. The support frame is then fixed to an external object using a fixing component, thus achieving the installation effect of the support frame. In the event of a worker's accidental fall, the safety rope will cause the reel to rotate. At this time, the drive component drives the moving plate to move towards the reel, causing the limiting teeth to insert into the safety rope. The safety rope is then prevented from moving due to the limiting teeth, thus stopping the worker's fall and providing protection. Through the design of the drive component and the limiting teeth, the movement of the safety rope can be restricted in time when a worker falls, preventing the worker from suffering impact force and improving worker safety.

[0010] The present invention is further configured such that: the driving assembly includes a slider slidably connected to the side wall of the moving plate; the side wall of the moving plate has a first groove for the slider to move up and down; the side wall of the support frame has a second groove for the slider to move horizontally; the side of the second groove away from the winding reel has a limiting groove for the slider to enter; the side of the moving plate away from the winding reel and the inside of the support frame are connected by a spring; when the slider enters the limiting groove, the spring is in a deformed and compressed state; and the support frame is provided with a driving component for driving the slider to separate from the limiting groove.

[0011] By adopting the above technical solution, when a worker falls, the driving component causes the slider to separate from the limiting groove, and the slider moves upward along the first slide groove, driving the slider into the second slide groove. At the same time, the spring loses its restraint and deforms to return to its original state, driving the moving plate to move. Simultaneously, the moving plate drives the slider to move horizontally along the second slide groove, and the moving plate drives the limiting teeth to insert into the safety rope body. This achieves the effect of driving the moving plate to move. When it is necessary to restore the moving plate, simply move the slider back into the limiting groove, driving the moving plate to move and causing the spring to deform and compress, thus completing the effect of restoring the moving plate and facilitating subsequent secondary use.

[0012] The present invention is further configured such that: the driving component includes a rotating rod rotatably connected to the outer wall of the support frame, the rotating rod passes through the support frame and is fixedly connected to the winding reel, a rotating plate is fixedly connected to the side wall of the rotating rod, a fixed frame is fixedly connected to the side wall of the support frame, the two ends of the fixed frame are respectively facing the rotating rod and the limiting groove, a wedge block is slidably connected inside the fixed frame, and limiting plates are fixedly connected to both sides of the fixed frame.

[0013] By adopting the above technical solution, when a worker falls, the safety rope body is affected by the worker's weight and inertia, increasing the speed of the safety rope body. This, in turn, increases the rotational speed of the rotating rod driven by the reel, and simultaneously increases the rotational speed of the rotating plate driven by the rotating rod. Due to the law of conservation of momentum and energy, the faster the rotational speed, the greater the impact force on the object. Therefore, when the rotating plate rotates to contact the wedge block, the rotating plate will apply an impact force to the wedge block. At this time, the wedge block will be affected by the impact force applied by the rotating plate, driving the wedge block to move along the inner wall of the fixed frame towards the limiting groove, and causing the wedge block to move towards the limiting groove. The inertia generated during movement causes the inclined surface of the wedge block to collide with the bottom of the slider. At this time, the bottom of the slider is affected by the impact of the wedge block, which drives the slider to move along the inclined surface of the wedge block and move upward along the first slide groove, and enter the second slide groove. This achieves the effect of driving the slider to separate from the limiting groove. At the same time, the inclined setting of the fixed frame can drive the wedge block back to its original position. When the operator is using it normally, because the operator's falling speed is relatively slow, the impact force exerted by the rotating plate on the wedge block is unlikely to drive the wedge block to contact the limiting block, thereby avoiding affecting the normal use of the support frame.

[0014] The present invention is further configured such that a roller is rotatably connected to the bottom of the wedge block.

[0015] By adopting the above technical solution, it is easier to drive the wedge block to move along the fixed frame, making it easier for the wedge block to come into contact with the slider.

[0016] The present invention is further configured such that: a protective cover is fixedly connected to the side of the support frame near the rotating plate, and the protective cover is provided with a sliding groove for the slider to slide.

[0017] By adopting the above technical solution, the rotating plate, wedge block, and fixed frame can be protected. At the same time, the setting of the slide groove three can facilitate the sliding block to return to its original position, thus avoiding affecting normal use.

[0018] The present invention is further configured such that: the fixing component includes a fixing plate, a screw, and an expansion bolt; both the fixing plate and the side wall of the support frame are provided with threaded holes for the screw to be installed; and the fixing plate is provided with a plurality of mounting holes for the expansion bolt to be inserted.

[0019] By adopting the above technical solution, when fixing the support frame to external objects such as walls, the fixing plate and the support frame are fixed together by screws, and then expansion bolts are inserted into the mounting holes to fix the fixing plate and the external objects together, thereby achieving the effect of fixing the support frame.

[0020] The present invention is further configured such that: the fixing component includes a fixing plate two and a screw two; the fixing plate two has a threaded hole two for the screw two to be installed; two elastic plates are fixedly connected to the side of the fixing plate two away from the support frame; a cavity is formed between the two elastic plates; and the cross-section of the elastic plates is arc-shaped; a sliding groove four is formed on the side wall of the elastic plate. A limiting frame is slidably connected to the sliding groove four.

[0021] By adopting the above technical solution, when fixing the support frame and external objects such as guardrails and security windows, the fixing plate and the support frame are fixed together by screw two. Then, the two elastic plates are moved to drive the external object into the cavity formed by the two elastic plates. Then, the limiting frame is inserted into the sliding groove. At this time, the external object is separated from the two elastic plates, thereby achieving the effect of fixing the support frame and the external object.

[0022] In summary, this utility model has the following beneficial effects: When a worker accidentally falls, the safety rope body will drive the reel to rotate. At this time, the driving component drives the moving plate to move towards the reel, and drives the limiting teeth to insert into the safety rope body. At this time, the safety rope body is affected by the limiting teeth, making it unable to move, thereby stopping the worker from falling and protecting the worker. Through the setting of the driving component and the limiting teeth, the movement of the safety rope body can be restricted in time when a worker falls, avoiding the worker from being subjected to impact force and improving the worker's safety.

[0035] A type of fall protection safety rope, such as Figures 1-8 As shown, the safety rope body includes a support frame 1. The support frame 1 has two through holes 2 at its top and bottom. A coil 3 is rotatably connected inside the support frame 1. A through groove 4 is provided on the side wall of the support frame 1, through which the safety rope body is wound onto the coil 3 and communicates with the through holes 2. A movable plate 5 is slidably connected inside the support frame 1. Several limiting teeth 6 are fixedly connected to the side of the movable plate 5 near the coil 3. The support frame 1 is equipped with a driving component for moving the movable plate 5 along the side wall of the support frame 1 and a fixing component for fixing the support frame 1 to external objects. When workers use the safety rope body for high-altitude operations, the safety rope body is looped, and then the looped portion of the safety rope body is inserted into the support frame 1 along the through groove 4, and the safety rope body is wound onto the coil 3. The safety rope body is positioned at the through hole 2, and then the support frame 1 is fixed to an external object via a fixing component, thus achieving the installation effect of the support frame 1. When a worker accidentally falls, the safety rope body will cause the winding reel 3 to rotate. At this time, the driving component drives the moving plate 5 to move towards the winding reel 3, and causes the limiting tooth 6 to insert into the safety rope body. At this time, the safety rope body is affected by the limiting tooth 6, making it unable to move, thereby stopping the worker from falling and protecting the worker. Through the setting of the driving component and the limiting tooth 6, the movement of the safety rope body can be restricted in time when a worker falls, avoiding the worker from being subjected to impact force and improving the worker's safety.

[0036] like Figures 1-8As shown, the driving assembly includes a slider 7 slidably connected to the side wall of the movable plate 5. The side wall of the movable plate 5 has a first groove 8 for the slider 7 to move up and down. The side wall of the support frame 1 has a second groove 9 for the slider 7 to move horizontally. A limiting groove 10 for the slider 7 to enter is provided on the side of the second groove 9 away from the reel 3. The side of the movable plate 5 away from the reel 3 and the interior of the support frame 1 are connected by a spring 11. When the slider 7 enters the limiting groove 10, the spring 11 is in a deformed and compressed state. The support frame 1 is provided with a driving component for driving the slider 7 to separate from the limiting groove 10. The driving component includes a rotating rod 12 rotatably connected to the outer wall of the support frame 1. The rotating rod 12 passes through the support frame 1 and is fixedly connected to the reel 3. A rotating plate 13 is fixedly connected to the side wall of the rotating rod 12. A fixed plate 13 is fixedly connected to the side wall of the support frame 1. The fixed frame 14 has its two ends facing the rotating rod 12 and the limiting groove 10, respectively. A wedge block 15 is slidably connected inside the fixed frame 14. Limiting plates 16 are fixedly connected to both sides of the fixed frame 14 to prevent the wedge block 15 from separating from the fixed frame 14 and to avoid affecting normal use. A protective cover 17 is fixedly connected to the side of the support frame 1 near the rotating plate 13. The protective cover 17 has a sliding groove 3 18 for the slider 7 to slide, which can protect the rotating plate 13, the wedge block 15, and the fixed frame 14. At the same time, the sliding groove 3 18 can easily drive the slider 7 back to its original position to avoid affecting normal use. A roller 29 is rotatably connected to the bottom of the wedge block 15, which can easily drive the wedge block 15 to move along the fixed frame 14, making it easier for the wedge block 15 to contact the slider 7.

[0037] When a worker falls, the safety rope is affected by the worker's weight and inertia, increasing its speed. This, in turn, increases the rotational speed of the reel 3 and the rotating rod 12, which in turn increases the rotational speed of the rotating plate 13. Due to the law of conservation of momentum and energy, the faster the rotational speed, the greater the impact force. Therefore, when the rotating plate 13 rotates to contact the wedge block 15, it applies an impact force to the wedge block 15. The wedge block 15, influenced by this impact force, moves along the inner wall of the fixed frame 14 towards the limiting groove 10. The inertia generated by the wedge block 15 during its movement causes its inclined surface to contact the bottom of the slider 7. When the two objects collide, the bottom of the slider 7 is affected by the impact of the wedge block 15, which drives the slider 7 to move along the inclined surface of the wedge block 15 and move the slider 7 upward along the first slide groove 8, and at the same time enter the second slide groove 9. At the same time, the spring 11 loses its restraint and deforms to restore its original shape, and drives the moving plate 5 to move. At this time, the moving plate 5 drives the slider 7 to move horizontally along the second slide groove 9, and the moving plate 5 drives the limiting tooth 6 to insert into the safety rope body, thereby achieving the effect of driving the moving plate 5 to move. When it is necessary to restore the moving plate 5, simply move the slider 7 to drive the slider 7 back into the limiting groove 10, and at the same time drive the moving plate 5 to move, and drive the spring 11 to deform and compress, thereby completing the effect of restoring the moving plate 5, which is convenient for subsequent secondary use.

[0038] Example 1, such as Figure 4 As shown, the fixing assembly includes a fixing plate 19, screws 20, and expansion bolts 21. Both the fixing plate 19 and the support frame 1 have threaded holes 22 for screws 20 to be installed on their side walls. The fixing plate 19 has several mounting holes 23 for the expansion bolts 21 to be inserted into. When fixing the support frame 1 to an external object such as a wall, the fixing plate 19 and the support frame 1 are fixed together by the screws 20. Then, the expansion bolts 21 are inserted into the mounting holes 23 to fix the fixing plate 19 to the external object, thereby achieving the effect of fixing the support frame 1.

[0039] Example 2: The fixing assembly includes a fixing plate 24 and screws 30. The fixing plate 24 has threaded holes 25 for screws 30 to be installed. Two elastic plates 26 are fixedly connected to the side of the fixing plate 24 away from the support frame 1, forming a cavity between the two elastic plates 26. The cross-section of the elastic plates 26 is arc-shaped, and the sidewall of the elastic plates 26 has a sliding groove 27. A limiting frame 28 is slidably connected to the sliding groove 27. When fixing the support frame 1 to external objects such as railings or security windows, the fixing plate 24 and the support frame 1 are fixed together by the screws 30. Then, the two elastic plates 26 are moved to drive the external object into the cavity formed by the two elastic plates 26. Then, the limiting frame 28 is inserted into the sliding groove 27. At this time, the external object is separated from the two elastic plates 26, thereby achieving the effect of fixing the support frame 1 and the external object.

[0040] The working principle of this utility model is as follows: When a worker uses the safety rope for high-altitude operations, the safety rope is looped. Then, the looped portion of the safety rope is placed into the support frame 1 along the through groove 4, and the safety rope is wound onto the reel 3, with the safety rope positioned at the through hole 2. The support frame 1 is then fixed to an external object, thus achieving the installation effect of the support frame 1. If a worker accidentally falls, the safety rope will cause the reel 3 to rotate. At this time, the safety rope is affected by the worker's weight and inertia, increasing its speed. This, in turn, causes the reel 3 to rotate faster, driving the rotating rod 12 to rotate faster. Simultaneously, the rotating rod 12 drives the rotating plate 13 to rotate faster. Due to the law of conservation of momentum and energy, the faster the rotation speed, the greater the impact force on the object. Therefore, when the rotating plate 13 rotates to contact the wedge block 15, the rotating plate 13 will exert an impact force on the wedge block 15. At this time, the wedge block 15 will be subjected to the impact exerted by the rotating plate 13. The force drives the wedge block 15 to move along the inner wall of the fixed frame 14 towards the limiting groove 10. The inertia generated by the wedge block 15 during its movement causes the inclined surface of the wedge block 15 to collide with the bottom of the slider 7. At this time, the bottom of the slider 7 is affected by the impact of the wedge block 15, causing the slider 7 to move along the inclined surface of the wedge block 15 and move upward along the first slide groove 8, entering the second slide groove 9. At the same time, the spring 11 loses its restraint and deforms to restore its original shape, driving the moving plate 5 to move. The moving plate 5 then drives the slider 7 to move horizontally along the second slide groove 9. The moving plate 5 also causes the limiting tooth 6 to insert into the safety rope body. At this time, the safety rope body is affected by the limiting tooth 6, preventing the safety rope body from moving, thus stopping the worker from falling and protecting the worker. Through the setting of the drive component and the limiting tooth 6, the movement of the safety rope body can be restricted in time when the worker falls, avoiding the worker from being subjected to impact force and improving the worker's safety.

[0041] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
