Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of scaffolding construction technology. Specifically, it relates to a wire rope anchoring device for cantilever scaffolding. Background Technology

[0002] Cantilevered scaffolding is a common type of scaffolding used in construction. It uses a cantilever structure to support the scaffolding outside the building, providing a working platform for construction workers. In cantilevered scaffolding, wire ropes are key load-bearing components, playing a crucial role in transferring loads and stabilizing the structure. The quality, strength, and anchoring stability of the wire ropes directly affect the overall safety performance of the scaffolding. If the wire ropes break, slip, or become unstable, it may lead to scaffolding collapse, causing personal injury and property damage.

[0003] Existing wire rope anchoring devices are often simple in structure and lack effective fixing and anti-slip measures, making the wire rope prone to slippage under stress. Furthermore, the simple structure may not be suitable for wire ropes of different diameters or cope with various complex situations that may arise during construction. Therefore, a wire rope anchoring device for cantilever scaffolding is designed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a wire rope anchoring device for cantilever scaffolding.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a wire rope anchoring device for cantilever scaffolding, including a connector, wherein the connector includes a screw rod and the front end of the screw rod is provided with a protruding head;

[0007] An embedded sleeve is provided on the outside of the connector. The embedded sleeve includes a threaded section and a telescopic section. The telescopic section is located at the front end of the embedded sleeve, and a retaining plate is embedded on the outside of the telescopic section.

[0008] A wire rope connecting block is disposed at the rear end of the screw. The wire rope connecting block includes a pressing block and a housing. The pressing block is disposed inside the housing, and a spring b is disposed between the bottom of the pressing block and the housing.

[0009] As a preferred embodiment of this utility model, a spring a is surrounded on the outside of the screw, and damping pads are fixed at both ends of the spring a. The damping pads are threadedly engaged with the screw, and the spring a is located at the rear end of the protruding head.

[0010] As a preferred technical solution of this utility model, at least three expansion joints are provided on the outer side of the expansion section, the expansion section is made of high-strength rubber material, and the clamping plate is made of metal spring material.

[0011] As a preferred technical solution of this utility model, the pressing block has an "I" shaped cross section, guide blocks are fixed on both sides of the bottom of the pressing block, and a guide groove adapted to the guide block is opened on the inner side of the outer shell.

[0012] As a preferred embodiment of this utility model, the guide block is made of rubber, and the thickness of the guide block is 1.1-1.3 times the width of the guide groove.

[0013] In a preferred embodiment of this utility model, the two ends of the spring b are fixedly connected to the pressing block and the outer shell, respectively. The pressing block is movably connected to the outer shell through the spring b, and a rope hole is provided on the surface of the outer shell.

[0014] As a preferred embodiment of this utility model, the surface of the outer shell is provided with at least two rope holes, the two rope holes are symmetrically arranged, and the rope holes are offset from the guide groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention effectively solves the problems of easy slippage of wire ropes under stress and poor adaptability of simple structures. By pressing the wire rope connecting block, the wire rope passes through, and the pressing block is lifted by the action of spring b, so that the wire rope is clamped by the outer shell and the pressing block. This allows the connecting block to adapt to wire ropes of different diameters, effectively preventing the wire rope from slipping. The expansion joint and clamping plate design of the expansion section enhance the anchoring force and adapt to the slight deformation of concrete, thus improving stability.

[0029] like Figure 1-5 As shown, this utility model provides a wire rope anchoring device for cantilever scaffolding, including a connector 10, the connector 10 including a screw 101, and a protruding head 104 provided at the front end of the screw 101;

[0030] An embedded sleeve 20 is provided on the outside of the connector 10. The embedded sleeve 20 includes a threaded section 201 and a telescopic section 202. The telescopic section 202 is located at the front end of the embedded sleeve 20, and a retaining plate 204 is embedded on the outside of the telescopic section 202.

[0031] The wire rope connecting block 30 is located at the rear end of the screw 101. The wire rope connecting block 30 includes a pressing block 301 and a housing 302. The pressing block 301 is located inside the housing 302. A spring b304 is provided between the bottom of the pressing block 301 and the housing 302.

[0032] Furthermore, in this embodiment, a spring a102 surrounds the outer side of the screw 101. Damping pads 103 are fixed at both ends of the spring a102. The damping pads 103 are threadedly engaged with the screw 101. The spring a102 is located at the rear end of the protruding head 104. The spring a102 provides elastic support and buffering. When the connecting piece 10 is subjected to external force, the spring a102 can absorb part of the impact force and reduce the direct pressure on the screw 101, thereby protecting the screw 101 and the entire connecting structure. By manually adjusting the position of the damping pad 103 on the screw 101, the extension length of the spring a102 can be changed, thereby adjusting the elastic force and buffering effect of the spring a102, so that it can be used under different working conditions, such as different loads or vibration environments.

[0033] In this embodiment, at least three expansion joints 203 are provided on the outer side of the expansion section 202. The expansion joints 203 enable the expansion section 202 to have good elastic deformation ability. When the expansion section 202 is compressed or stretched by external force, the expansion joints 203 allow the expansion section 202 to deform, thereby adapting to the small displacement or deformation of the embedded sleeve 20 in the concrete, ensuring the tight connection between the embedded sleeve 20 and the screw 101. The expansion section 202 is made of high-strength rubber material. The material of the expansion section 202 allows the protruding head 104 to open the expansion section 202 after the screw 101 enters. The clamping plate 204 is made of metal spring sheet material. The clamping plate 204 provides additional anchoring force. After the expansion section 202 is opened, the clamping plate 204 is tightly attached to the inner wall of the concrete layer 40, increasing the friction between the embedded sleeve 20 and the concrete.

[0034] In this embodiment, the pressing block 301 has an "I" shaped cross-section. The pressing block 301 can better disperse stress when bearing pressure, reducing the possibility of deformation. Guide blocks 303 are fixed on both sides of the bottom of the pressing block 301. The inner side of the outer shell 302 is provided with a guide groove 306 that matches the guide block 303. When the pressing block 301 moves relative to the outer shell 302, the guide block 303 cooperates with the guide groove 306 on the inner side of the outer shell 302 to ensure that the pressing block 301 moves along a predetermined trajectory and prevents the pressing block 301 from deviating during the movement.

[0035] In this embodiment, the guide block 303 is made of rubber, and the thickness of the guide block 303 is 1.1-1.3 times the width of the guide groove 306. The design of the guide block 303 and the guide groove 306 increases the contact area between the guide block 303 and the guide groove 306, improves the stability and reliability of the guide, and ensures that the guide block 303 is squeezed by the guide groove 306 and always maintains close contact with the guide groove 306, preventing shaking or loosening caused by excessive gaps, thereby ensuring the precise operation and stable connection of the wire rope connecting block 30.

[0036] In this embodiment, the two ends of the spring b304 are fixedly connected to the pressing block 301 and the outer shell 302, respectively. The pressing block 301 is movably connected to the outer shell 302 through the spring b304. The surface of the outer shell 302 is provided with a rope hole 305. The spring b304 provides elastic support and restoring force for the pressing block 301. When the pressing block 301 is pressed by an external force, the spring b304 is compressed and stores elastic potential energy. When the external force is removed, the spring b304 releases the elastic potential energy and pushes the pressing block 301 back to its original position. Due to the shape of the pressing block 301, when the pressing block 301 is pressed, the gaps on both sides of the pressing block 301 are aligned with the rope hole 305, so that the wire rope 50 can pass through. After the pressing block 301 is released, the pressing block 301 is lifted by the spring, and the wire rope 50 is clamped by the force of the outer shell 302 and the pressing block 301.

[0037] In this embodiment, at least two rope holes 305 are provided on the surface of the outer shell 302. The two rope holes 305 are symmetrically arranged and the rope holes 305 are offset from the guide groove 306. The offset arrangement of the rope holes 305 and the guide groove 306 avoids interference between the wire rope 50 and the guide groove 306 when the wire rope 50 passes through the rope hole 305.

[0038] Specifically, during the construction of the concrete structure, holes are drilled in the cured concrete, and the pre-embedded sleeve 20 is embedded in the concrete, ensuring that the threaded section 201 and the expansion section 202 of the pre-embedded sleeve 20 are fully embedded in the concrete, and the threaded section 201 is screwed into the concrete hole. The front end of the screw 101 is inserted into the threaded section 201 of the pre-embedded sleeve 20. By rotating the screw 101, the screw 101 and the thread of the pre-embedded sleeve 20 are tightly fitted. At the same time, the protruding head 104 at the top of the screw 101 is in the expansion section 202, and the expansion section 202 is opened. The expansion section 202 abuts against the hole in the concrete through the outer clamping plate 204. The wire rope 50 is passed through the rope hole 305 of the wire rope connecting block 30 at the rear end of the screw 101.

[0039] When the wire rope 50 needs to pass through the rope hole 305, press down the pressing block 301, compress the spring b304, and the wire rope 50 passes through the rope hole 305 and both sides of the pressing block 301 with an "I" shaped cross section. After passing through, release the pressing block 301, and the compressed spring b304 returns to its original state. At this time, the pressing block 301 is lifted by the spring b304, and its two sides are misaligned with the recessed positions corresponding to the rope hole 305, clamping the part through which the wire rope 50 passes. Considering the load-bearing capacity of the wire rope 50, depending on the actual situation, it is selected whether to fix the wire rope connecting block 30 to the concrete with bolts, and the screw 101 is fully screwed into the pre-embedded sleeve 20. The screw 101 is welded to the wire rope connecting block 30 to improve the firmness.

[0040] It should be noted that, due to the large force on the wire rope during actual construction, using only a spring to clamp the wire rope 50 can easily cause the pressing block 301 to break open due to the force of the wire rope 50. Therefore, connecting rods 307 are threadedly fitted on the inner sides of both the pressing block 301 and the outer shell 302, and a sleeve 308 is provided between two connecting rods 307. The combination structure of connecting rods 307 and sleeves 308 is provided at least three times. The cross-section of the connecting end of the connecting rod 307 and the sleeve 308 is T-shaped. One connecting rod 307 is threadedly fitted to the sleeve 308, and the other connecting rod 307 is slidably connected to the sleeve 308. One end is used to assist the spring b304 in connecting the pressing block 301 to the outer shell 302, and the other end can cooperate with the extension and retraction of the spring b304, thus avoiding the situation where a single spring cannot clamp the wire rope 50.

[0041] It is worth noting that the preload, dimensions, and thickness of the load-bearing components of this application, such as springs and connecting rods 307, need to be designed according to the load conditions of the wire rope 50 to ensure the effectiveness of the structure.

[0042] The connector 10, screw 101, spring, damping pad 103, embedded sleeve 20, clamping plate 204, pressing block 301, outer shell 302, guide block 303, concrete layer 40, wire rope 50 and other components of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
