Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, and in particular to a safety rope anti-abrasion limiting device and a clamp-type safety rope installation device. Background Technology

[0002] In various scenarios such as high-altitude operations, outdoor rescue, construction, and fire rescue, safety ropes serve as core equipment for ensuring the safety of workers, and their service life and structural integrity directly affect operational safety. However, in actual use, safety ropes often experience continuous friction with anchor points, sharp edges, or other objects. Long-term wear can easily lead to a decrease in rope strength and an increased risk of breakage. Therefore, reliable anti-wear technologies are needed to extend their service life and ensure safe use.

[0003] Existing technology proposes a wear-resistant and displacement-resistant device for suspended platform safety ropes, consisting of detachably connected limiting components and connecting components. The limiting component includes an angle plate and mutually perpendicular lugs and wings on both sides. The angle plate and the two winglets together form a groove for accommodating the safety rope. The lugs have mounting holes for easy connection to a fixed structure; the winglets have through holes for a threaded rod to pass through, which is then locked with a nut, thus confining the safety rope within the groove. This structure can, to a certain extent, suppress the displacement of the safety rope and reduce direct friction and wear between it and the external corner of the wall or column.

[0004] However, this device still has certain limitations in practical applications. On the one hand, when facing external corners with different angles such as 90°, 120°, and 135° commonly found in building structures, the device struggles to adapt to various angle changes and achieve a tight fit with the corner surface, affecting installation stability. On the other hand, the device lacks effective adaptability and adjustment capabilities for safety ropes of different diameters commonly used in construction. When the safety rope diameter is too small, it is prone to swaying within the slot, resulting in poor limiting effect; when the diameter is too large, it may not be able to smoothly pass through the threaded rod and nut for locking and fixing. These limitations reduce the applicability of the device in diverse construction scenarios.

[0005] Therefore, there is an urgent need to propose a safety rope anti-abrasion limiting device and a clamp-type safety rope installation equipment to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a safety rope anti-wear limiting device and a clamp-type safety rope installation equipment, which can be adapted to different angles and different diameters of installation ropes to meet the needs of diverse construction scenarios.

[0007] To achieve this objective, the present invention adopts the following technical solution: The safety rope anti-abrasion limiting device includes two limiting components, each of which includes: One end of the rotating plate along the length direction is rotatably connected to the other end of the rotating plate of the limiting component along the length direction via a rotating shaft, so that the two rotating plates can rotate relative to each other around the rotating shaft and fit one-to-one with two adjacent reference surfaces of the external corner. The rotating plate is provided with a fixing hole for detachably fixing the rotating plate to the reference surface by fasteners. Two limiting plates are fixed to the same side of the rotating plate at intervals along the width direction of the rotating plate and together with the rotating plate to form a limiting groove. The limiting grooves of the two limiting components form a continuous limiting channel that spans the external corner for accommodating and guiding the safety rope. The limiting plates are provided with at least two limiting holes at intervals along the direction perpendicular to the rotating plate, and the limiting holes on the two limiting plates are coaxially aligned one-to-one. The limiting member can be selectively inserted into the limiting holes at corresponding heights on the two limiting plates to limit the safety rope within the continuous limiting channel.

[0008] Preferably, the limiting member includes an anti-detachment head, a threading rod, and two support legs. One end of the threading rod along its length is connected to the anti-detachment head, and the two support legs are connected to the end of the threading rod away from the anti-detachment head, and the two support legs are bendable.

[0009] Preferably, the inner wall of the limiting groove is lined with an anti-wear pad.

[0010] Preferably, each of the two rotating plates is provided with at least one connecting lug plate at its connecting end. The connecting lug plate has a through hole. The connecting lug plates of the two rotating plates are arranged in an alternating manner, and the through holes of each connecting lug plate are coaxially aligned. The rotating shaft passes through the coaxially aligned through holes.

[0011] Preferably, the outer edge of the connecting ear plate is a smoothly transitioned curved surface.

[0012] Preferably, the height of the limiting plate gradually decreases along the direction away from the rotating shaft, and the limiting hole is opened at one end of the limiting plate near the rotating shaft.

[0013] Preferably, both the rotating plate and the limiting plate are made of PVC.

[0014] A clamp-type safety rope installation device is used to lay safety ropes on load-bearing components. The device comprises at least one connecting component and at least two of the aforementioned safety rope anti-abrasion limiting devices. The number of the safety rope anti-abrasion limiting devices corresponds one-to-one with the number of external corners of the load-bearing component. Each limiting component further comprises a connecting plate, which is vertically connected to a rotating plate. Two connecting plates located on the same reference plane of two adjacent external corners are arranged facing each other and connected by the connecting component.

[0015] Preferably, each of the limiting components further includes two connecting plates, and the two connecting plates are located on both sides of the two limiting plates.

[0016] Preferably, the connecting assembly includes a connecting screw and a locking nut, the connecting plate is provided with a connecting hole, and the connecting screw passes through the connecting holes on the two connecting plates in sequence and is screwed to the locking nut.

[0017] The beneficial effects of this utility model are: This utility model provides a safety rope anti-wear limiting device. Two limiting components have rotating plates connected at one end along their length via a rotating shaft, allowing them to rotate relative to each other around the shaft. When facing external angles of 90°, 120°, 135°, etc., the included angle of the two rotating plates can be adjusted so that they correspond one-to-one with two adjacent reference surfaces of the external angle. Secure installation is then achieved through fixing holes on the rotating plates and fasteners, thus solving the problems of existing devices being unable to adapt to various external angles and having poor installation stability. Simultaneously, the two limiting plates of each limiting component are vertically fixed to the same side of the rotating plate and form a limiting groove. The limiting grooves of the positioning components together form a continuous limiting channel spanning the external corner to accommodate the safety rope. The limiting plate has at least two limiting holes spaced apart along the direction perpendicular to the rotating plate. Depending on the different diameters of the safety rope, the limiting component can be inserted into the limiting hole at the corresponding height. This avoids the problem of the safety rope swaying in the channel and having poor limiting effect when the diameter is too small, and also prevents the safety rope from being unable to be locked and fixed by the limiting component when the diameter is too large. This improves the applicability in various construction scenarios. At the same time, through the synergistic effect of the continuous limiting channel and the limiting component, the direct friction between the safety rope and the external corner is further reduced, which improves the service life of the safety rope.

[0018] This utility model provides a clamp-type safety rope installation device. By vertically setting a connecting plate on the rotating plate of each limiting component, and using the connecting component to firmly connect the connecting plates of adjacent safety rope anti-wear limiting devices located on the same reference plane, it is not necessary to drill holes on the reference plane to connect with the rotating plate, thereby reducing damage to the load-bearing components. Furthermore, this clamp-type safety rope installation device integrates the advantages of the safety rope anti-wear limiting device and can be adapted to various angles and diameters of safety ropes.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-7 As shown, this utility model provides a safety rope anti-wear limiting device, including two limiting components 1. Each limiting component 1 includes a rotating plate 11, a limiting member 13, and two limiting plates 12. One end of the rotating plate 11 along the length direction is rotatably connected to one end of the rotating plate 11 of the other limiting component 1 along the length direction via a rotating shaft 2, so that the two rotating plates 11 can rotate relative to each other around the rotating shaft 1 and correspond to two adjacent reference surfaces of the external corner. The rotating plate 11 is provided with a fixing hole 110 for detachably fixing the rotating plate 11 to the reference surface by fasteners; the two limiting plates 12 along the length direction are connected to the rotating plate 11. The rotating plate 11 is fixed perpendicularly to the same side of the rotating plate 11 at intervals in the width direction, and together with the rotating plate 11, they form a limiting groove. The limiting grooves of the two limiting components 1 form a continuous limiting channel that spans the external corner, which is used to accommodate and guide the safety rope 100. The limiting plate 12 has at least two limiting holes 120 at intervals along the direction perpendicular to the rotating plate 11, and the limiting holes 120 on the two limiting plates 12 are coaxially aligned and correspond one-to-one. The limiting member 13 can be selectively inserted into the limiting holes 120 at corresponding heights on the two limiting plates 12 to limit the safety rope 100 in the continuous limiting channel.

[0026] The rotating plates 11 of the two limiting components 1 are rotatably connected at one end along the length direction via a rotating shaft 2, allowing them to rotate relative to each other around the shaft 2. When facing external corners of different angles such as 90°, 120°, or 135°, the included angle of the two rotating plates 11 can be adjusted so that they correspond one-to-one with the two adjacent reference surfaces of the external corner. Then, a stable installation is achieved by using fasteners with fixing holes 110 on the rotating plates 11, thereby solving the problem that existing devices are difficult to adapt to various external corner angles and have poor installation stability. At the same time, the two limiting plates 12 of each limiting component 1 are vertically fixed to the same side of the rotating plate 11 and form a limiting groove. The limiting grooves of the two limiting components 1 together constitute a connection that spans the external corner. The continuous limiting channel accommodates the safety rope 100, and the limiting plate 12 is provided with at least two limiting holes 120 spaced apart along the direction of the vertical rotating plate 11. Depending on the different diameters of the safety rope 100, the limiting member 13 can be selected to be inserted into the limiting hole 120 at the corresponding height. This can avoid the problem of the safety rope 100 swinging in the channel and having poor limiting effect when the diameter is too small, and can also prevent the safety rope 100 from being unable to be locked and fixed by the limiting member 13 when the diameter is too large. This improves the applicability in various construction scenarios. At the same time, through the synergistic effect of the continuous limiting channel and the limiting member 13, the direct friction between the safety rope 100 and the external corner is further reduced, which improves the service life of the safety rope 100.

[0027] Reference Figure 1 From left to right, the rotating plates 11 of the two limiting components 1 present four states: "not rotated", "rotated 90°", "rotated 120°" and "rotated 60°".

[0028] In this embodiment, the limiting plate 12 has two limiting holes 120 spaced apart along the direction of the vertical rotating plate 11.

[0029] In other embodiments, the limiting plate 12 is provided with three limiting holes 120 spaced apart along the direction perpendicular to the rotating plate 11. The number of limiting holes 120 is not specifically limited here.

[0030] In this embodiment, the fastener is a screw.

[0031] Specifically, such as Figure 1 and 2As shown, the limiting member 13 includes an anti-detachment head 131, a through rod 132 and two support legs 133. One end of the through rod 132 along the length direction is connected to the anti-detachment head 131, and the two support legs 133 are connected to the end of the through rod 132 away from the anti-detachment head 131, and the two support legs 133 are bendable. When it is necessary to limit the safety rope 100 in the continuous limiting channel, first select the limiting holes 120 of the corresponding height on the two limiting plates 12 according to the diameter of the safety rope 100, and then insert the two legs 133 of the pin into the limiting holes 120. At this time, the through rod 132 will span between the two limiting plates 12, and together with the inner wall of the limiting groove, it will form a constraint on the safety rope 100. The anti-detachment head 131, because its size is larger than the diameter of the limiting hole 120, will fit tightly against the outer surface of one limiting plate 12. After the two legs 133 completely pass through the limiting hole 120 of the other limiting plate 12, bend the legs 133 toward the limiting plate 12 to prevent the limiting member 13 from coming out of the limiting hole 120.

[0032] Specifically, the inner wall of the limiting groove is lined with an anti-abrasion pad. The anti-abrasion pad is in direct contact with the safety rope 100, which can effectively isolate the rigid friction between the safety rope 100 and the inner wall of the limiting groove. When the safety rope 100 moves along the continuous limiting channel or is pulled by external force, the anti-abrasion pad can absorb the frictional impact force through its own flexible material, preventing the outer fiber of the safety rope 100 from being worn and broken due to direct friction with the metal inner wall of the limiting groove, thus significantly extending the service life of the safety rope 100.

[0033] The abrasion-resistant pad can be made of rubber or ultra-high molecular weight polyethylene.

[0034] Specifically, each of the two rotating plates 11 has at least one connecting lug at its connecting end. The connecting lugs have through holes, and the connecting lugs of the two rotating plates 11 are arranged in a staggered pattern. The through holes of each connecting lug are coaxially aligned, and the rotating shaft 2 passes through these coaxially aligned through holes. The two rotating plates 11 can flexibly rotate relative to each other around the axis of the rotating shaft 2, thereby closely fitting the external angle reference surface at different angles and enhancing the adaptability of the device. Furthermore, the staggered arrangement of the connecting lugs reduces the overall volume of the connection point, avoiding interference in narrow spaces and making the overall structure of the device more compact.

[0035] More specifically, the outer edge of the connecting ear plate is a smoothly transitioned curved surface. When the device is subjected to the tensile force of the safety rope 100 or external impact, the smoothly transitioned edge can disperse the stress concentration point, avoid the right-angle edge from cracking or breaking due to long-term stress, extend the service life of the connecting ear plate, and at the same time avoid local wear of the safety rope 100, thus improving the service life of the safety rope 100.

[0036] Specifically, such as Figure 1As shown, the height of the limiting plate 12 gradually decreases along the direction away from the rotating shaft 2, and the limiting hole 120 is opened at the end of the limiting plate 12 near the rotating shaft 2. Since the height of the limiting plate 12 gradually decreases along the direction away from the rotating shaft 2, the operator can easily insert or remove the safety rope 100 from the lower end of the limiting groove without having to forcefully thread it through the end of the device; and, by opening the limiting hole 120 at the highest point of the limiting plate 12 near the rotating shaft 2, the limiting member 13 can restrain the safety rope 100 close to the back of the corner bend, preventing the safety rope 100 from jumping out of the limiting groove when under force.

[0037] Specifically, both the rotating plate 11 and the limiting plate 12 are made of PVC. PVC is lightweight, reducing the overall weight of the rotating plate 11 and the limiting plate 12. This not only makes it easier for operators to carry the equipment for high-altitude installation, but also reduces the burden on them during operation. Furthermore, the smooth surface and certain toughness of PVC reduce frictional damage when the safety rope 100 comes into contact with the equipment.

[0038] like Figures 5-7 As shown, this utility model also proposes a clamp-type safety rope installation device for arranging the safety rope 100 on the load-bearing component 200. The clamp-type safety rope installation device includes at least two safety rope anti-abrasion limiting devices and at least one connecting component 3. The number of safety rope anti-abrasion limiting devices corresponds one-to-one with the number of external corners of the load-bearing component 200. Each limiting component 1 also includes a connecting plate 14, which is vertically connected to the rotating plate 11. Two connecting plates 14 located on the same reference plane of two adjacent external corners are arranged facing each other and connected by the connecting component 3.

[0039] By vertically setting a connecting plate 14 on the rotating plate 11 of each limiting component 1, and using the connecting component 3 to firmly connect the connecting plates 14 of adjacent safety rope anti-wear limiting devices located on the same reference plane, it is not necessary to drill holes on the reference plane to connect with the rotating plate 11, thereby reducing damage to the load-bearing component 200. Furthermore, this clamp-type safety rope installation equipment integrates the advantages of the safety rope anti-wear limiting device and can be adapted to various external angles and safety ropes 100 of different diameters.

[0040] like Figure 5 and Figure 6 As shown, the load-bearing component 200 is a wall. The clamp-type safety rope installation equipment includes two safety rope anti-abrasion limiting devices. The rotating plate 11 of each safety rope anti-abrasion limiting device is adjusted to an angle that matches the external corner of the wall. The two connecting plates 14 are perpendicular to the same reference plane of two adjacent external corners on the top surface of the wall. At this time, the two connecting plates 14 are tightly connected by the connecting component 3. The two rotating plates 11 that are not located on the same reference plane are connected to the wall by fasteners.

[0041] like Figure 7As shown, the load-bearing component 200 is a column or beam. The clamp-type safety rope installation equipment includes four safety rope anti-abrasion limiting devices. The two rotating plates 11 of each safety rope anti-abrasion limiting device are adjusted to a 90° angle that matches the corresponding external angle of the column or beam. The two connecting plates 14 located on the same reference plane are connected by the connecting component 3, so that the four safety rope anti-abrasion limiting devices can form a "circular" clamp fixing structure around the column or beam. At this time, it is not necessary to connect the rotating plate 11 to the column or beam with fasteners.

[0042] Specifically, each limiting component 1 also includes two connecting plates 14, which are located on both sides of the two limiting plates 12. The two connecting plates 14 are distributed on both sides of the limiting plates 12 and work together with the connecting components 3 to make the clamping force of the entire clamping device evenly distributed, further enhancing the stability of the installation.

[0043] Specifically, the connecting assembly 3 includes a connecting screw 31 and a locking nut 32. The connecting plate 14 has connecting holes, and the connecting screw 31 passes through the connecting holes on both connecting plates 14 and is screwed onto the locking nut 32. By tightening the locking nut 32, the locking force of the connecting screw 31 on the two connecting plates 14 can be controlled, ensuring that the clamp-type safety rope installation equipment is firmly fixed to the load-bearing component 200 and will not slip or shift. Secondly, the screw-nut connection method is a standard and quick mechanical connection, requiring no special tools for installation and disassembly. This makes the entire equipment easy to assemble and disassemble, allowing for quick transfer and reuse between different work locations or load-bearing components 200, improving the equipment's versatility and economy.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
