Description

Technical Field

[0001] This invention relates to the field of fall protection technology for high-altitude operations, specifically to a fall protection rope retraction and deployment device for high-altitude operations. Background Technology

[0002] After construction is completed, the scaffolding needs to be dismantled, which requires the participation of relevant personnel. As the scaffolding is gradually dismantled, its rigid support strength gradually decreases. Therefore, workers must pay attention to their own safety during dismantling operations to avoid accidents such as slipping or falling from heights due to scaffolding breakage.

[0003] Currently, fall arrest devices exist for dismantling building scaffolding. These devices primarily involve fixing two wall clamps together, with a connecting steel wire rope between them. Workers' safety belt hooks can slide freely along the wire rope, using the connection between the safety belt and the rope for safety protection. However, this method has the following problems: 1. Due to the significant impact of a sudden fall, the cushioning provided by the safety belt is too weak. Insufficient cushioning will subject workers to a large inertial impact, seriously endangering their lives and health.

[0004] 2. At the same time, if the hook on the safety belt is only attached to a single steel wire rope, the excessive tension under a huge downward impact can easily cause the steel wire rope to break. Furthermore, a sudden fall may cause the worker to lose balance, resulting in violent swaying or rotation during the fall, which could easily cause the worker to collide with the building and cause secondary injuries.

[0005] Therefore, in order to solve the problems of insufficient buffer protection provided by existing technologies and weak stability of safety belt attachments, this invention provides a high-altitude operation fall protection guide rope retraction device. Summary of the Invention

[0006] This invention provides a high-altitude operation fall protection guide rope retraction device to solve the problems of insufficient buffer protection and weak stability of the safety belt attachment point in related technologies.

[0007] The present invention provides a high-altitude operation fall protection guide rope deployment and retraction device, comprising: a main fall protection unit, wherein a cooperating suspension unit is provided on the main fall protection unit.

[0008] The main fall protection unit includes a wall clamp, and between the two wall clamps arranged opposite each other, from left to right, there are auxiliary fall protection parts and steel wire connection parts.

[0009] The auxiliary fall arrestor includes a mounting and positioning component. Two wall clamps arranged opposite each other are connected by the mounting and positioning component, and the mounting and positioning component is fixedly connected to the two wall clamps by bolts. The mounting and positioning component has a sliding groove. A rectangular groove is opened on the mounting and positioning component on the right side of the sliding groove.

A buffer assembly is installed in the mounting through groove. A semi-circular limit block is fixedly installed at the bottom of the sliding groove on both the front and rear sides of the mounting through groove.

[0010] In one embodiment, the sliding hook assembly includes a main sliding block, which is slidably disposed in a sliding groove. A sliding connector is slidably disposed in the sliding groove and above the main sliding block. The lower end of the sliding connector is evenly provided with a margin groove. An automatic telescopic rod is fixedly installed in the middle of the top of each margin groove. The lower end of the automatic telescopic rod is fixedly connected to the main sliding block. A spring is sleeved on each automatic telescopic rod. One end of the spring is fixedly connected to the sliding block, and the other end is fixedly connected to the sliding connector. An extension plate is fixedly installed on the right end of the main sliding block, and a hook ring is fixedly installed on the extension plate.

[0011] In one embodiment, the buffer assembly includes two bolts. A bearing positioning plate is fixedly installed on the lower end of the mounting positioning member and located on the lower side of the mounting slot by two bolts that are symmetrically arranged front and back. A plug-in base plate is fixedly installed on the upper end of the bearing positioning plate and located in the mounting slot. Two springs are symmetrically fixedly installed on the upper end of the plug-in base plate. A lifting slide plate is fixedly connected to the upper end of the two springs. The lifting slide plate is connected to the mounting slot by a sliding fit.

[0012] In one embodiment, the cooperating suspension unit includes hooks, and hooks are respectively attached to the auxiliary anti-fall part and the wire connection part. The lower end of each hook is fixedly installed with an installation cylinder. A positioning partition is fixedly installed inside the installation cylinder. A buffer rope group is provided inside the installation cylinder and above the positioning partition. An auxiliary deceleration group is provided on the installation cylinder and below the positioning partition.

[0013] In one embodiment, the buffer rope assembly includes a sliding connecting plate. The sliding connecting plate is installed inside the cylinder and slidably disposed above the positioning partition. A connecting rope is fixedly connected to the middle of the lower end of the sliding connecting plate. A spring is sleeved on the connecting rope. One end of the spring is fixedly connected to the positioning partition, and the other end is fixedly connected to the sliding connecting plate. Sliding round rods are evenly arranged circumferentially at the lower end of the sliding connecting plate, and the sliding round rods slide in cooperation with the positioning partition. After the connecting rope passes through the positioning partition and the installation cylinder, it is connected to a connecting ring together with another connecting rope.

[0014] In one embodiment, the auxiliary deceleration group includes a fixed support. Fixed supports are evenly arranged circumferentially at the inner bottom end of the fixed cylinder. A rotating plate is rotatably connected to the fixed support. An installation bracket is fixedly connected to the end of the rotating plate near the connecting rope. A circular roller is rotatably connected to the installation bracket.

[0015] In one embodiment, the wire connection includes a buffer, and buffers are fixedly installed at the opposite ends of the two wall clamps arranged in opposite directions, with a wire rope connecting the buffers together.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] 1. This invention provides a high-altitude work fall protection guide rope deployment and retraction device, comprising a main fall protection unit and a suspension unit working together. In the event of a fall, the buffer rope group provides initial cushioning, followed by auxiliary deceleration group for further deceleration, preventing workers from experiencing enormous impact force due to a sudden fall. Simultaneously, since the wire rope is positioned between two buffers, it provides secondary cushioning. The sliding hook assembly, subjected to downward pull, also provides tertiary cushioning protection for the worker due to the buffer assembly below. These three cushioning mechanisms work together to reduce the impact force on the worker, effectively improving the cushioning protection and providing effective safety assurance. A sudden fall may cause the worker to lose balance or control, resulting in violent swaying or rotation during the fall. Two hooks are installed at two points to stabilize the worker during the fall. Simultaneously, the buffer rope groups at both points can evenly distribute the impact force, preventing the wire rope from breaking due to concentrated force. The overall combined effect greatly improves the safety of high-altitude work.

[0018] 2. The suspension unit of this invention, through the elastic support of three pairs of sliding connecting plates with springs, makes the descent of the connecting rope more gradual compared to a system without buffering. Then, the auxiliary deceleration group limits the speed of the connecting rope, which ultimately slows down the descent speed of the connecting rope, preventing the connecting rope from breaking and reducing the impact force on the workers during the fall.

[0019] 3. The buffer component of this invention can reduce the impact of a sudden fall if the worker falls. The sliding hook component presses down on the lifting slide plate and moves downward. The spring 2 provides a buffering force, which can reduce the impact of the sudden fall and reduce the impact force on the worker.

[0020] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the high-altitude operation fall prevention guide rope launching and retracting device provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Please see Figure 1 A high-altitude operation fall protection guide rope deployment and retraction device includes: a main fall protection unit 1 and a suspension unit 2, wherein the main fall protection unit 1 is provided with the suspension unit 2.

[0038] Please see Figure 2 The main fall protection unit 1 includes a wall clamp 11, an auxiliary fall protection part 12 and a steel wire connection part 13. The auxiliary fall protection part 12 and the steel wire connection part 13 are arranged sequentially from left to right between the two wall clamps 11 arranged in opposite directions.

[0039] Please see Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The auxiliary fall arrestor 12 includes a mounting positioning component 121, bolt 122, sliding groove 123, rectangular groove 124, sliding hook assembly 125, mounting through groove 126, buffer assembly 127, and semi-circular limiting block 128. The mounting positioning component 121 is connected between two wall clamps 11 arranged opposite each other, and the mounting positioning component 121 is fixedly connected to the two wall clamps 11 by bolt 122. The mounting positioning component 121 has a sliding groove 123. A rectangular groove 124 is opened on the mounting positioning component 121 and located on the right side of the sliding groove 123. The sliding hook assembly 125 is slidably arranged in the sliding groove 123. The mounting through groove 126 is evenly opened on the mounting positioning component 121 and located on the lower side of the sliding groove 123. The buffer assembly 127 is arranged in the mounting through groove 126. Semi-circular limiting blocks 128 are fixedly arranged at the bottom end of the sliding groove 123 and on both the front and rear sides of the mounting through groove 126.

[0040] Please see Figure 2 and Figure 3 The wire connection part 13 includes a buffer 131 and a wire rope 132. The two wall clamps 11 arranged in opposite directions are fixedly installed with buffers 131 at their opposite ends, and the buffers 131 are connected together by a wire rope 132.

[0041] Please see Figure 9 The hanging unit 2 includes a hook 21, a mounting cylinder 22, a positioning partition 23, a buffer rope assembly 24, and an auxiliary deceleration assembly 25. The auxiliary anti-fall part 12 and the wire connection part 13 are respectively hooked to the hook 21. The lower end of the hook 21 is fixedly installed with the mounting cylinder 22. The positioning partition 23 is fixedly installed inside the mounting cylinder 22. The buffer rope assembly 24 is arranged inside the mounting cylinder 22 and above the positioning partition 23. The auxiliary deceleration assembly 25 is arranged on the mounting cylinder 22 and below the positioning partition 23.

[0042] First, establish fixed distances and points along the same straight line. Then, at each fixed point, fix two steel pipes of the same specification between the top of the wall and the ground, respectively. Wall clamps 11 are fixedly installed on each steel pipe, and both wall clamps 11 are securely clamped to the side wall. Finally, the auxiliary fall arrestor 12 and the steel wire connection 13 are sequentially fixed between the two wall clamps 11. At this point, the main fall arrestor unit 1 is installed. Figure 1As shown; the ends of the two buffer rope groups 24 are fixedly connected to the safety protective clothing worn by the workers when performing high-altitude operations, that is, the hanging unit 2 and the safety protective clothing form a complete protective set; after the workers put on the safety protective clothing, they hang the two hooks 21 on the sliding hook assembly 125 and the wire rope 132 respectively, and then, according to the working position, they move the sliding hook assembly 125 to the upper end of the buffer assembly 127 closest to their working position (that is, between the two semi-circular limit blocks 128), and then they can enter the working state.

[0043] If a worker accidentally falls during the operation, the buffer rope assembly 24 provides initial cushioning, followed by auxiliary deceleration assembly 25 for further deceleration, preventing the worker from experiencing a huge impact force due to a sudden fall. Simultaneously, since the wire rope 132 is positioned between the two buffers 131, the two buffers provide secondary cushioning. The sliding hook assembly 125, subjected to downward tension, also provides tertiary cushioning protection due to the buffer assembly 127 below. These three points work together to reduce the impact force on the worker, effectively improving the cushioning and protection effect. A sudden fall may cause the worker to lose balance or control, resulting in violent swaying or rotation during the fall. However, because the two hooks 21 are attached at two points, the worker can be stabilized and prevented from falling. At the same time, the buffer rope assemblies 24 at both points can evenly distribute the impact force, preventing the wire rope 132 from breaking due to concentrated force. The overall effect of the device greatly improves the safety of high-altitude operations.

[0044] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 The sliding hook assembly 125 includes a main sliding block 1251, a sliding connector 1252, a clearance groove 1253, an automatic telescopic rod 1254, a spring 1255, an extension block 1256, and a hook ring 1257. The main sliding block 1251 is slidably disposed within the sliding groove 123. The sliding connector 1252 is slidably disposed within the sliding groove 123 and above the main sliding block 1251. Clearance grooves 1253 are evenly distributed at the lower end of the sliding connector 1252. An automatic telescopic rod 1254 is fixedly installed at the top center of the measuring groove 1253. The lower ends of the automatic telescopic rods 1254 are fixedly connected to the main sliding block 1251. A spring 1255 is sleeved on each of the automatic telescopic rods 1254. One end of the spring 1255 is fixedly connected to the sliding block, and the other end is fixedly connected to the sliding connector 1252. An extension block 1256 is fixedly installed on the right end of the main sliding block 1251. A hook ring 1257 is fixedly installed on the extension block 1256.

[0045] One of the hooks, 21, is attached to the hook ring 1257. When the sliding hook assembly 125 is moved, the main sliding block 1251 and the sliding connector 1252 move synchronously. When it needs to pass the semicircular limit block 128, the main sliding block 1251 slides past the semicircular limit block 128, and the spring 1255 is compressed, causing the automatic telescopic rod 1254 to retract into the allowance groove 1253. At this time, the distance between the main sliding block 1251 and the sliding connector 1252 is... The size is reduced to allow the main sliding block 1251 to pass over the semicircular limit block 128. When the two semicircular limit blocks 128 at the appropriate position are stable (i.e., the upper end of the buffer assembly 127), the spring 1255 returns to its original state and drives the automatic telescopic rod 1254 to reset, thus tensioning the connection between the main sliding block 1251 and the sliding connector 1252, so that the main sliding block 1251 and the sliding connector 1252 can be stably located at the upper end of one of the buffer assemblies 127.

[0046] Please see Figure 6 and Figure 7 The buffer assembly 127 includes bolt 1271, a bearing positioning plate 1272, a plug-in base plate 1273, a spring 1274, and a lifting slide plate 1275. The bearing positioning plate 1272 is fixedly installed on the lower end of the mounting positioning component 121 and located on the lower side of the mounting through groove 126 by bolts 1271 arranged symmetrically at the front and back. The plug-in base plate 1273 is fixedly installed on the upper end of the bearing positioning plate 1272 and located in the mounting through groove 126. The spring 1274 is fixedly installed on the upper end of the plug-in base plate 1273 arranged symmetrically at the front and back. The lifting slide plate 1275 is fixedly connected to the upper end of the spring 1274. The lifting slide plate 1275 and the mounting through groove 126 are connected by a sliding fit.

[0047] When the sliding hook assembly 125 is above the lifting slide plate 1275, under normal conditions, due to the elastic support of the second spring 1274, the upper surface of the lifting slide plate 1275 is flush with the bottom surface of the sliding groove 123. If a worker suddenly falls, the downward force will cause the sliding hook assembly 125 to press down on the lifting slide plate 1275 and move downward. Due to the buffering effect of the second spring 1274, the sudden impact of the fall can be reduced, thereby reducing the impact force on the worker.

[0048] Please see Figure 9 and Figure 10The buffer rope assembly 24 includes a sliding connecting plate 241, a connecting rope 242, a spring 243, a sliding round rod 244, and a connecting ring 245. The sliding connecting plate 241 is slidably disposed inside the installation cylinder 22 and above the positioning partition 23. The connecting rope 242 is fixedly connected to the middle of the lower end of the sliding connecting plate 241. The spring 243 is sleeved on the connecting rod. One end of the spring 243 is fixedly connected to the positioning partition 23, and the other end is fixedly connected to the sliding connecting plate 241. The sliding round rod 244 is evenly disposed around the lower end of the sliding connecting plate 241, and the sliding round rod 244 slides in cooperation with the positioning partition 23. After the connecting rope 242 passes through the positioning partition 23 and the installation cylinder 22, it is connected to the connecting ring 245 together with another connecting rope 242.

[0049] When the connecting rope 242 is subjected to a sudden downward force, it will cause the sliding connecting plate 241 to move downward. Due to the elastic support of the spring 243 on the sliding connecting plate 241, the descent of the connecting rope 242 is more gradual compared to a situation without buffering. During this process, the downward movement of the sliding connecting plate 241 will cause the sliding rod 244 to slide down. The bottom end of the sliding rod 244 will press against the corresponding auxiliary deceleration group 25 on the lower side. The auxiliary deceleration group 25 will then limit the speed of the connecting rope 242, which will ultimately slow down the descent speed of the connecting rope 242, preventing the rope from breaking and reducing the impact force on the workers during the fall.

[0050] Please see Figure 10 , Figure 11 and Figure 12 The auxiliary deceleration group 25 includes a fixed support 251, a rotating plate 252, a mounting bracket 253, a cylindrical roller 254, and a stop plate 255. Fixed supports 251 are evenly arranged circumferentially at the inner bottom end of the mounting cylinder 22. The rotating plate 252 is rotatably connected to the fixed support 251. The mounting bracket 253 is fixedly connected to the end of the rotating plate 252 near the connecting rope 242. The cylindrical roller 254 is rotatably connected to the mounting bracket 253. The stop plate 255 is fixedly connected between the end of the fixed support 251 near the wall of the mounting cylinder 22 and the mounting cylinder 22.

[0051] When the sliding rod 244 presses down synchronously on the rotating plate 252 located below it, the rotating plate 252 rotates around the fixed support 251, causing the rotating plate 252 on the side closer to the connecting rope 242 to rotate upward. This causes the roller 254 to rotate upward synchronously to buffer and decelerate the connecting rope 242, preventing it from falling rapidly and causing injury to the workers due to inertial impact. The stop plate 255 is set so that the rotating plate 252 can be kept in a stable horizontal position due to the downward pressure. When the rotating plate 252 is in a horizontal position, the rotating roller 254 is slightly close to the circumference of the connecting rope 242, which can limit the downward movement of the connecting rope 242 to a certain extent. At the same time, the arc surface of the rotating roller 254 will not damage the connecting rope 242 and there is no large breaking force.

[0052] The working principle of this invention is as follows: If a worker accidentally falls due to a misstep during operation, the buffer rope group 24 can provide initial cushioning, and the auxiliary deceleration group 25 can provide further deceleration, preventing the worker from experiencing a huge impact force due to a sudden fall. At the same time, since the wire rope 132 is set between the two buffers 131, the two buffers 131 can provide secondary cushioning. The sliding hook assembly 125, which is subjected to downward pull, will also provide tertiary cushioning protection due to the buffer assembly 127 set below. The three points work together to reduce the impact force of the fall on the worker, effectively improving the cushioning and protection effect.
