Description

Technical Field

[0001] This invention relates to the field of climbing safety protection technology, and in particular to a vertical climbing safety protection device. Background Technology

[0002] In the field of vertical climbing safety protection, especially in high-altitude work scenarios such as power transmission towers and communication towers, vertical climbing safety protection devices are crucial equipment for ensuring the safety of workers. These devices typically connect to foot spikes or similar support points on the climbing structure via adjustable clamping or fixing components, and form fall protection with the help of safety belts or connecting straps.

[0003] The prior art discloses a safety protection device for climbing power transmission towers. When climbing power transmission towers, one can wear climbing gloves and hold the clamping device, put the thimble assembly on the tower foot spikes, and use fingers to adjust the adjustable fasteners to complete the fixation.

[0004] While the device provides basic climbing protection, several issues remain in practical use: The lack of an effective anti-accidental locking structure means the fasteners are prone to rotation during non-operational activities due to physical contact, tool scraping, or other accidental contact. This can loosen the connection between the clamping part and the tower feet, reducing protection reliability and increasing the risk of falls. Furthermore, the existing adjustment mechanism has poor adaptability to tower feet sizes, making it difficult to flexibly accommodate feet of different diameters. This limits the device's versatility on various tower structures, impacting ease of use and applicability. Summary of the Invention

[0008] Optionally, the upper mounting groove is further provided with a slide rod, and a spring is sleeved on the outside of the slide rod. A reset block is fixedly installed on the top surface of the upper rack. The reset block is sleeved on the slide rod and is pushed by the spring to drive the insertion rod to move. The lower mounting groove has an operating groove at its end, and the lower rack is exposed through the operating groove.

[0009] Optionally, the adjustment frame has a U-shaped structure, including a horizontal bar and two vertical bars. The horizontal bar is hung on the tower footings, and the two ends of the rotating shaft are respectively installed on the two vertical bars.

[0010] Optionally, a slide rail is provided in one of the vertical rods of the adjusting frame. The slide rail is arranged vertically, and the side of the limiting block has a recessed platform. The recessed platform is embedded in the slide rail to restrict the rotation of the limiting block relative to the adjusting frame.

[0011] Optionally, a lifting block and a guide block are respectively installed at both ends of the rotating shaft. A sliding groove is opened in the vertical rod on one side of the adjusting frame, and a guide groove is opened in the vertical rod on the other side. The lifting block is slidably installed in the sliding groove. An adjusting screw and a guide rod are provided in the sliding groove. The lifting block is threadedly connected to the adjusting screw and has a through hole that cooperates with the guide rod. The guide block is slidably installed in the guide groove.

[0012] Optionally, a fixing shell is provided on the outer side of the vertical rod, the fixing shell is connected to the guide block, and a torsion spring is installed inside the fixing shell, with both ends of the torsion spring being fixedly connected to the fixing shell and the rotating shaft, respectively.

[0013] Optionally, the adjusting frame is also provided with a double-ended screw, the two ends of which are respectively rotatably installed in the two vertical rods on both sides of the adjusting frame.

[0016] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages: 1. The vertical climbing safety protection device of the present invention includes an adjusting frame, fasteners, and a locking mechanism. The adjusting frame is used to hang on the tower footings, and a rotating shaft is installed on its lower side. The fastener is sleeved on the rotating shaft and fixed by abutting its top against the bottom side of the tower footing. The locking mechanism consists of a limiting block and a plug-in assembly. The limiting block is sleeved on the rotating shaft and embedded in the side of the adjusting frame to prevent relative rotation. A slot is opened on the side of the limiting block, and the plug-in assembly is located inside the fastener and can be inserted into the slot, thereby fixing the relative angle between the fastener and the adjusting frame. The present invention automatically maintains the position of the fastener in the non-operating state through mechanical interlocking, avoiding the fastener from loosening due to accidental contact or vibration, thus improving the reliability of protection. The cooperation between the locking mechanism and the adjusting frame ensures that the fastener will not rotate, solving the problem of accidental contact and preventing loosening due to accidental contact, thereby improving the reliability of protection.

[0017] 2. This invention includes a locking mechanism and an adjusting mechanism. When fasteners are not in use, the spring force in the locking mechanism drives the insertion rod, causing one end of the insertion rod to insert into the slot on one side of the limiting block. This locks and secures the rotating shaft and fasteners, ensuring tight contact between the clamping part on the fastener and the tower foot nail. This prevents loosening and accidental contact that could cause the handle to move, disengaging the clamping part on the fastener from the tower foot nail and affecting its limiting and securing effect, thereby improving the protective effect of the equipment.

[0018] 3. The adjustment mechanism can flexibly adjust the distance between the two clamps and the height of the fastener according to the diameter of the tower foot nail, accurately adapting to tower foot nails of different diameters, effectively expanding the product's application scenarios, achieving multiple uses in one machine, and taking into account both practicality and convenience.

Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Example 1 like Figure 1 As shown, this embodiment proposes a vertical climbing safety protection device, including: an adjusting frame 2, a fastener 3, and a locking mechanism; the adjusting frame 2 is hung on the tower footing 1, and a rotating shaft 6 is installed on the lower side of the adjusting frame 2 and the tower footing 1; the fastener 3 is sleeved on the rotating shaft 6, and the top of the fastener 3 can abut against the bottom side of the tower footing 1; as shown Figure 2 , Figure 3 , Figure 4 As shown, the locking mechanism includes a limiting block 13 and a plug-in assembly. The limiting block 13 is sleeved on the rotating shaft 6, and one side of the limiting block 13 is embedded in the side of the adjusting frame 2. A slot 30 is provided on the side of the limiting block 13. The plug-in assembly is located inside the fastener 3 and can be plugged into the slot 30 of the limiting block 13, thereby fixing the relative angle between the fastener 3 and the adjusting frame 2 through the limiting block 13.

[0023] The adjusting frame 2 serves as the overall installation base, hooked onto the tower footing 1, providing a stable mounting platform for subsequent components. A rotating shaft 6 is installed on the adjusting frame 2 below the tower footing 1. The rotating shaft 6 provides rotational support for the fastener 3, allowing the fastener 3 to rotate and adjust, thus enabling the top of the fastener 3 to abut against the bottom of the tower footing 1, forming an initial tightening. A limiting block 13 in the locking mechanism is fitted onto the rotating shaft 6, with one side of the limiting block 13 embedded in the side of the adjusting frame 2, preventing rotation of the limiting block 13 relative to the adjusting frame 2 and ensuring that the slot 30 on the side of the limiting block 13 remains in a fixed position, guaranteeing the alignment of the plug-in components. The plug-in component is located inside the fastener 3 and can be plugged into the slot 30 of the limiting block 13. By fixing the limiting block 13 and the adjusting bracket 2, the position of the fastener 3 is locked and fixed, so that the pressing part 32 on it is always kept in a locked state, preventing it from loosening or moving due to accidental contact, thus improving the protection effect.

[0024] like Figure 4 As shown, the plug-in assembly includes an upper rack 17, a plug rod 20, a lower rack 16, and a gear 15. The fastener 3 has an upper mounting groove 22 and a lower mounting groove 21. The upper rack 17 is located in the upper mounting groove 22, the lower rack 16 is located in the lower mounting groove 21, and the gear 15 is located between the upper rack 17 and the lower rack 16 and meshes with them. The plug rod 20 is fixed to the end of the upper rack 17 and can be inserted into the slot 30 of the limiting block 13.

[0025] The components of the plug-in assembly form a linkage structure within the fastener 3. The upper mounting slot 22 and lower mounting slot 21 within the fastener 3 provide independent mounting spaces for the upper rack 17 and lower rack 16, respectively, ensuring the stability of the rack's movement trajectory. A gear 15 is positioned between the upper rack 17 and lower rack 16 and meshes with them, allowing the movement of the lower rack 16 to be transmitted to the upper rack 17 via the gear 15, achieving reverse linkage between the upper rack 17 and lower rack 16. The insertion rod 20 is fixed to the end of the upper rack 17. As the upper rack 17 moves, the insertion rod 20 can synchronously move closer to or further away from the slot 30 of the limiting block 13, thereby achieving insertion or disengagement.

[0026] The upper mounting groove 22 is also provided with a slide rod 18, and a spring 19 is sleeved on the outside of the slide rod 18. A reset block 29 is fixedly installed on the top surface of the upper rack 17. The reset block 29 is sleeved on the slide rod 18 and is pushed by the spring 19 to drive the insertion rod 20 to move. The lower mounting groove 21 has an operating groove at its end, and the lower rack 16 is exposed through the operating groove.

[0027] The spring force of spring 19 can push the insertion rod 20 to automatically insert into the slot 30 of the limit block 13 when not in operation, realizing automatic locking of the device. This eliminates the need for manual locking, solving the problems of cumbersome and easily forgotten manual locking. The operating slot allows operators to easily adjust the fastener 3 by pushing the lower rack 16 to rotate the gear 15, which in turn causes the upper rack 17 to pull the insertion rod 20 out of the slot 30, thus unlocking the device. This balances the convenience of automatic locking with the operability of manual unlocking. Simultaneously, the lower rack 16 does not protrude from the fastener 3, preventing accidental contact.

[0028] The adjustment frame 2 has a U-shaped structure, including a horizontal bar and two vertical bars. The horizontal bar is hung on the tower foot nail 1, and the two ends of the rotating shaft 6 are respectively installed on the two vertical bars.

[0029] The method of attaching the horizontal bar to the tower footing 1 does not require additional fixing connectors. The operator only needs to place the horizontal bar on the tower footing 1 to complete the initial installation. The two vertical bars support both ends of the rotating shaft 6 to prevent the rotating shaft 6 from bending and deforming due to excessive force on one side, ensuring the normal rotation of the rotating shaft 6, and thus ensuring that the fastener 3 can be adjusted smoothly.

[0030] like Figure 2 As shown, a slide rail 14 is provided in one of the vertical rods of the adjusting frame 2. The slide rail 14 is arranged vertically, and the side of the limiting block 13 has a recessed platform that is embedded in the slide rail 14, restricting the rotation of the limiting block 13 relative to the adjusting frame 2. The limiting block 13 can move vertically along the slide rail 14, and its position can be adapted to the adjustment of the height of the rotating shaft 6, ensuring that the locking mechanism can work normally at different height positions.

[0031] Lifting blocks 9 and guide blocks 12 are respectively installed at both ends of the rotating shaft 6. A sliding groove 26 is opened in the vertical rod on one side of the adjusting frame 2, and a guide groove 27 is opened in the vertical rod on the other side. The lifting block 9 is slidably installed in the sliding groove 26. An adjusting screw 7 and a guide rod 8 are provided in the sliding groove 26. The lifting block 9 is threadedly connected to the adjusting screw 7 and has a through hole that cooperates with the guide rod 8. The guide block 12 is slidably installed in the guide groove 27.

[0032] When the operator rotates the adjusting screw 7, due to the threaded connection between the lifting block 9 and the adjusting screw 7, and the guiding effect of the guide rod 8, the lifting block 9 can move smoothly up and down along the slide groove 26, simultaneously driving the rotating shaft 6 to move up and down synchronously. The guide block 12 slides synchronously within the guide groove 27, ensuring the consistency of movement at both ends of the rotating shaft 6 and preventing the rotating shaft 6 from tilting. This structure allows for fine-tuning of the height of the rotating shaft 6 according to the diameter of the tower foot nail 1, thereby adjusting the height of the fastener 3 and solving the problem of not being able to adapt to different foot nails.

[0033] A fixing shell 10 is provided on the outside of the vertical rod. The fixing shell 10 is connected to the guide block 12. A torsion spring 11 is installed inside the fixing shell 10. The two ends of the torsion spring 11 are fixedly connected to the fixing shell 10 and the rotating shaft 6, respectively.

[0034] When the locking mechanism is unlocked, the torsion spring 11 releases its elastic potential energy, causing the rotating shaft 6 to rotate, thereby automatically resetting the fastener 3 to its initial compressed state. The fixed shell 10 can protect the torsion spring 11, preventing dust, rainwater and other impurities in the high-altitude environment from affecting the performance of the torsion spring 11 and extending its service life.

[0035] like Figure 3 As shown, the adjustment frame 2 is also provided with a double-headed screw. The two ends of the double-headed screw are respectively rotatably installed in the vertical rods on both sides of the adjustment frame 2. A pair of adjustment blocks 24 are threaded on the double-headed screw. A clamping block 25 is provided on the lower side of the adjustment block 24. The inner side of the clamping block 25 has an arc-shaped curved surface for clamping the tower foot nail 1.

[0036] When the operator rotates the double-ended screw, the two adjusting blocks 24 move closer or further apart due to the reverse thread engagement between the adjusting blocks 24 and the double-ended screw. This causes the clamping blocks 25 to move synchronously, adjusting the distance between them. The arc-shaped surface on the inner side of the clamping blocks 25 increases the contact area with the tower foot spikes 1, improving clamping stability and preventing slippage between the clamping blocks 25 and the foot spikes. This structure allows the device to accommodate tower foot spikes 1 of different diameters, eliminating the need for operators to replace the device with a special one for different diameters, thus reducing equipment costs.

[0037] like Figure 4 As shown, the fastener 3 includes a hook part 31, a rotating handle 33 and a pressing part. The rotating handle 33 is located on the lower side of the pressing part, and the top surface of the pressing part is serrated to abut against the bottom side of the tower foot nail 1.

[0038] The addition of the handle 33 increases the operator's lever arm, making it easier to rotate the fastener 3 and improving operational convenience. The serrated structure on the top surface of the crimping part increases the friction with the bottom side of the tower foot nail 1, preventing slippage between the crimping part and the foot nail, ensuring the fastener 3 effectively clamps the foot nail, and improving the protective reliability of the device.

[0039] like Figure 1 As shown, the hook part 31 has a through hole, and a hook ring 4 is hooked in the through hole. A connecting strap 5 is connected to the lower side of the hook ring 4 to prevent the worker from falling further.

[0040] Specifically: The vertical climbing safety protection device includes a tower foot spike 1, an adjusting frame 2 on the outside of the tower foot spike 1, a rotating shaft 6 rotatably mounted inside the adjusting frame 2, a fastener 3 sleeved on the outside of the rotating shaft 6, and a locking mechanism inside the fastener 3. The adjusting frame 2 is connected to the tower foot spike 1 through the adjusting mechanism. One end of the rotating shaft 6 is rotatably sleeved and connected to a fixed shell 10 outside the adjusting frame 2, and a torsion spring 11 is installed on the outside of the fixed shell 10 on the rotating shaft 6. A guide block 12 is symmetrically arranged on one side of the fixed shell 10, and a guide groove 27 adapted to the guide block 12 is symmetrically opened on one side of the adjusting frame 2. This facilitates the sliding connection between the fixed shell 10 and the adjusting frame 2 through the cooperation of the guide block 12 and the guide groove 27, providing a guiding foundation for the linkage of subsequent structures, and limiting the fixed shell 10 to fix the torsion spring 11, providing power for the subsequent use of the torsion spring 11 to reset and rotate the rotating shaft 6.

[0041] The locking mechanism includes a limiting block 13, which is rotatably sleeved on the outer wall of the rotating shaft 6 and located between the fastener 3 and the adjusting frame 2. A slide rail 14 is symmetrically provided on one side of the inner wall of the adjusting frame 2, and a recessed platform adapted to the slide rail 14 is symmetrically provided on one side of the limiting block 13. Through the sliding cooperation between the slide rail 14 and the recessed platform, the movement trajectory of the limiting block 13 is restricted, providing support for the stable operation of the locking mechanism.

[0042] The locking mechanism also includes a gear 15, which is rotatably mounted within the fastener 3. A lower rack 16 and an upper rack 17 are symmetrically arranged on the upper and lower sides of the gear 15, and both the lower rack 16 and the upper rack 17 mesh with the gear 15. The fastener 3 has an upper mounting groove 22 and a lower mounting groove 21 respectively inside. The lower rack 16 is slidably mounted in the lower mounting groove 21, and the upper rack 17 is slidably mounted in the upper mounting groove 22. A sliding rod 18 is provided above the upper rack 17 within the upper mounting groove 22. A reset block 29 and a spring 19 are sleeved on the outside of the sliding rod 18. The reset block 29... The lower side is fixedly connected to the upper rack 17. The fastener 3 has an adjustment groove 28 that communicates with the upper mounting groove 22 on the side near the limit block 13. One end of the upper rack 17 is installed in the adjustment groove 28 and the other end of the rod 20 is inserted into the slot 30 opened on the side wall of the limit block 13. The two ends of the torsion spring 11 are fixedly connected to the fixed shell 10 and the rotating shaft 6 respectively. Through the meshing transmission of the gear 15 with the lower rack 16 and the upper rack 17, and the elastic force of the spring 19, the automatic locking and unlocking of the rod 20 is realized. No additional power is required. The structure is compact and highly reliable.

[0043] The limiting block 13 is cylindrical, and the insert rod 20 and the upper rack 17 form an L-shape. One end of the fastener 3 is provided with an operating groove corresponding to the lower rack 16. The cylindrical limiting block 13 and the insert rod 20 cooperate to lock the fastener 3. The operating groove makes it easy to press the lower rack 16 with a tool or finger, improving the convenience of adjustment.

[0044] The adjustment mechanism includes a bidirectional screw 23, which is rotatably mounted on the inner side of the top of the adjustment frame 2. Adjustment blocks 24 are symmetrically sleeved on the outer wall of the bidirectional screw 23, and the adjustment blocks 24 are threadedly connected to the bidirectional screw 23. A clamping block 25 is connected to the lower end of the adjustment block 24, and the clamping block 25 is located outside the tower foot nail 1. The spacing of the clamping block 25 is adjusted by the bidirectional screw 23 to adapt to tower foot nails 1 of different diameters.

[0045] The adjusting frame 2 has symmetrically arranged sliding grooves 26 on its left and right inner walls. Adjusting screws 7 and guide rods 8 are respectively arranged symmetrically in the sliding grooves 26, and the adjusting screws 7 are rotatably connected to the inner walls of the sliding grooves 26. Lifting blocks 9 are arranged in the sliding grooves 26, and the two ends of the lifting blocks 9 are respectively sleeved on the outside of the adjusting screws 7 and the guide rods 8. The lifting blocks 9 are threadedly connected to the adjusting screws 7. The lifting blocks 9 are sleeved on the outside of the rotating shaft 6, and the lifting blocks 9 are rotatably connected to the rotating shaft 6 through bearings. By adjusting the height of the lifting blocks 9 by adjusting the adjusting screws 7, the position of the fastener 3 can be adjusted up and down, improving the environmental adaptability of the device.

[0046] One end of the bidirectional screw 23 is connected to a side knob outside the adjusting frame 2, and the lower end of the adjusting screw 7 is connected to a lower knob outside the adjusting frame 2. The clamping block 25 has an arc-shaped curved surface with the same center as the tower foot nail 1 on its inner side wall. The side knob and the lower knob facilitate manual operation and adjustment. The clamping block 25 with the arc-shaped curved surface can fit tightly with the tower foot nail 1, enhancing clamping stability and preventing slippage.

[0047] The fastener 3 consists of a hook part 31, a rotating handle 33, and a clamping part 32. The top of the clamping part 32 is serrated. The hook part 31 is connected to the connecting strap 5 through the hanging ring 4. The clamping part 32, which is serrated at one end, can increase the friction with the tower foot nail 1 and improve the locking effect. The connection method between the hook part 31 and the hanging ring 4 facilitates quick installation and removal of the connecting strap 5, thereby improving work efficiency.

[0048] During use, when the protective device needs to be installed, it is fitted onto the outside of the tower foot nail 1 and installed and adapted through the adjustment mechanism. Rotating the bidirectional screw 23 causes the adjusting block 24 to move, which in turn causes the clamping block 25 to move closer to or further away, thus allowing the clamping block 25 to tightly clamp tower foot nails 1 of different diameters. On the other hand, rotating the adjusting screw 7 causes the adjusting screw 7 to be threadedly driven by the lifting block 9, which moves the lifting block 9 up and down along the guide rod 8, thereby adjusting the height position of the rotating shaft 6 and the fastener 3 to meet different installation requirements. During adjustment, the rotating shaft 6 and the fixed shell 10 will move up and down synchronously with the rotating shaft 6.

[0049] After installation, during normal use, the fastener 3 is in the unlocked state. Operators can rotate the handle 33 to make the fastener 3 rotate around the shaft 6, so that the clamping part 32 can loosen or clamp the tower foot nail 1, so as to facilitate the adjustment of the fixed position during climbing. At the same time, the guide block 12 on the fixed shell 10 slides along the guide groove 27 of the adjustment frame 2, and the torsion spring 11 deforms during the rotation of the shaft 6, providing elasticity for reset.

[0050] When the fastener 3 does not need to be adjusted, the locking mechanism comes into play: the spring force of the spring 19 pushes the reset block 29, the reset block 29 drives the upper rack 17 to move, the upper rack 17 drives the insert rod 20 to move and insert into the slot 30 of the limit block 13, restricting the rotation of the rotating shaft 6 and the fastener 3, keeping the pressing part 32 in a locked state, preventing loosening due to accidental contact, etc., and ensuring work safety.

[0051] When it is necessary to readjust the fastener 3, manually operate the lower rack 16 in the operating slot. The lower rack 16 drives the gear 15 to rotate, and the gear 15 then drives the upper rack 17 to move, causing the insert rod 20 to exit from the slot 30, releasing the lock on the fastener 3. The operator can then rotate the handle 33 normally for adjustment.

[0052] While the specific embodiments of the present invention have been described above, they are not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
