Description
Technical Field
[0001] The utility model relates to a buckle device, in particular to a safety main rope buckle device for the maintenance of a trestle bridge. Background Art
[0002] With the rapid economic development and the acceleration of the urbanization process, the demand for various infrastructure construction projects is increasing day by day, especially for the expansion and improvement of the transportation network. As an important passage connecting different regions, the trestle bridge plays a key role in fields such as ports, docks, and bridge construction. Due to being exposed to the outdoor environment for a long time and frequent use, the regular maintenance of the trestle bridge has become a necessary measure to ensure traffic safety and smoothness.
[0003] At present, the maintenance work of the trestle bridge mainly relies on traditional manual methods, that is, using scaffolding or mobile platforms for high-altitude operations. High-altitude operations themselves have relatively high risks. Especially in adverse weather conditions, workers are more likely to face the possibility of falling and other accidental injuries. The safety main rope buckle device is mainly used to provide a reliable fixed point for the operators to reduce the risks brought by high-altitude operations.
[0004] However, when the traditional buckle device was designed, it did not fully consider the changes in the operating environment, and its adjustment range was limited. It could not well adapt to steel ropes with different diameters or shapes. This means that when facing different operating conditions, different buckle devices may need to be replaced, increasing the complexity and cost of operation. In addition, most of the existing buckle devices are integrally formed fixed structures, which are difficult to be quickly adjusted according to the operating needs in actual use. This is not flexible enough for situations where the working position needs to be frequently changed or the length of the safety rope needs to be adjusted, further exacerbating the inconvenience of operation and low efficiency. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a safety main rope buckle device for the maintenance of a trestle bridge, aiming to improve adaptability and flexibility, simplify operation, reduce costs, and enhance safety.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A safety main rope buckle device for the maintenance of a trestle bridge, comprising a U-shaped card seat and a fixing plate. The U-shaped card seat is fixed to the fixing plate through a connecting mechanism, and a locking area is formed between the U-shaped card seat and the fixing plate. A lock catch is also connected to the U-shaped card seat, and a through hole for the main rope to pass through is opened on the lock catch.
[0007] Preferably, the connecting mechanism comprises two connecting bolts and two connecting nuts. At both ends of the U-shaped card seat, fitting plates are bent and arranged respectively. One end of the connecting bolt sequentially passes through the fixing plate and the fitting plate and is then screwed with the connecting nut.
[0008] Preferably, the locking buckle includes a rotating shaft, a locking ring and a connecting ring. The rotating shaft is rotatably connected to the U-shaped clamping seat, and after passing through the U-shaped clamping seat, the rotating shaft is fixed to the locking ring. The connecting ring is hinged to the lower part of the rotating shaft through a pin shaft, and the through hole is formed in the connecting ring.
[0009] Preferably, the locking buckle includes a fixed shaft, a connecting sleeve and two suspension rings. The upper end of the fixed shaft is fixed to the U-shaped clamping seat, the connecting sleeve is rotatably connected to the fixed shaft, and each suspension ring is connected to one side of the connecting sleeve through an adjusting screw rod. The through hole is arranged on the suspension ring.
[0010] Preferably, a limiting shaft is connected to the suspension ring, and a circlip is connected to one end of the limiting shaft after passing through the suspension ring.
[0011] Preferably, corrosion-resistant layers are respectively coated on the surfaces of the U-shaped clamping seat and the fixing plate.
[0012] Preferably, a plurality of holes for the anchor bolts to pass through are formed in the fixing plate to fix the fixing plate on the stack bridge deck.
[0013] Compared with the prior art, the advantages of the present utility model are as follows: This device effectively solves the deficiencies of traditional buckle devices in terms of adjustment range, operation convenience and fixing firmness, providing a safer and more reliable guarantee for high-altitude operators. The U-shaped clamping seat is fixed to the fixing plate through a connecting mechanism to form a safe locking area for fixing the entire buckle device on the stack bridge to ensure the stability of the device. The U-shaped clamping seat can be flexibly adjusted according to steel wire ropes of different diameters to adapt to various working conditions. The design of the locking buckle further improves the operation flexibility. It can easily fix the main rope to avoid accidental detachment of the main rope and ensure the safety of operators. This design enables operators to quickly and conveniently adjust the position and locking degree of the buckle to adapt to different working environments and requirements and improve work efficiency. In addition, this device has a simple structure and convenient installation. When in use, only the U-shaped clamping seat needs to be installed on the fixing plate without complex operation steps.

Specific implementation manner
[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0022] Embodiment 1: As shown in the figure, a safety mother rope buckle device for overhauling a trestle includes a U-shaped card seat 1 and a fixed plate 2. The U-shaped card seat 1 is fixed to the fixed plate 2 through a connecting mechanism 3, and a locking area 4 is formed between the U-shaped card seat 1 and the fixed plate 2. A locking buckle 5 is further connected to the U-shaped card seat 1, and a through hole 6 for the mother rope to pass through is provided on the locking buckle 5.
[0023] When installing this device, the following steps are included:
[0024] 1. Select a suitable position: Select a suitable installation position according to the operation requirements. Usually, a strong and safe structure should be selected, for example, the steel beam of the trestle or other strong support structures.
[0025] 2. Fix the fixed plate 2: Install the fixed plate 2 at the selected position. Bolts, screws or other firm fixing methods can be additionally used to ensure that the fixed plate 2 is firmly connected to the trestle.
[0026] 3. Install the U-shaped card seat 1: Fix the U-shaped card seat 1 to the fixed plate 2 through the connecting mechanism 3 to ensure firm connection, so that the entire buckle device can be fixed.
[0027] 4. Thread the main rope: Thread the main rope through the through hole 6 on the locking buckle 5.
[0028] 6. Check the fixing condition: Check the connection condition of the U-shaped clamping seat 1, the fixing plate 2 and the locking buckle 5 to ensure that all components are firmly connected and that the main rope is firmly locked.
[0029] In this embodiment, the connecting mechanism 3 includes two connecting bolts 8 and two connecting nuts 9. At both ends of the U-shaped clamping seat 1, fitting plates 10 are bent and arranged. One end of the connecting bolt 8 sequentially passes through the fixing plate 2 and the fitting plate 10 and is screwed with the connecting nut 9.
[0030] In the above structure, the fitting plates 10 bent and arranged at both ends of the U-shaped clamping seat 1 can, on the one hand, closely fit with the fixing plate 2, and on the other hand, also provide a fixing point for the perforation of the connecting bolt 8. After one end of the connecting bolt 8 sequentially passes through the fixing plate 2 and the fitting plate 10, it is screwed with the connecting nut 9, thus firmly fixing the U-shaped clamping seat 1 on the fixing plate 2. The two connecting bolts 8 are respectively fixed at both ends of the U-shaped clamping seat 1, effectively enhancing the stability and safety of the device.
[0031] Embodiment Two: As shown in the figure, different from Embodiment One, the locking buckle 5 is rotatably connected to the U-shaped clamping seat 1. The locking buckle 5 includes a rotating shaft 11, a locking ring 12 and a connecting ring 13. The rotating shaft 11 is rotatably connected to the U-shaped clamping seat 1, and after passing through the U-shaped clamping seat 1, the rotating shaft 11 is fixed to the locking ring 12. The connecting ring 13 is hinged to the lower part of the rotating shaft 11 through a pin shaft 14, and the through hole 6 is opened on the connecting ring 13.
[0032] In the above structure, the rotating shaft 11 is rotatably connected to the U-shaped clamping seat 1, enabling the entire locking buckle 5 to rotate and adjust the angle within a certain range around the rotating shaft 11, facilitating the accurate threading and fixing of the main rope. The locking ring 12 is fixedly connected to the rotating shaft 11, neither affecting the rotation of the rotating shaft 11 nor reliably preventing the rotating shaft 11 from disengaging from the U-shaped clamping seat 1. The connecting ring 13 is hinged to the lower part of the rotating shaft 11 through the pin shaft 14, and the through hole 6 for the main rope to pass through is opened on the connecting ring 13. The pin shaft 14 hinged manner can adjust the final position and angle of the through hole 6, facilitating the accurate threading and fixing of the main rope, and greatly improving the convenience of threading and extracting the main rope.
[0033] Embodiment Three: As shown in the figure, different from Embodiment Two, the locking buckle 5 includes a fixed shaft 15, a connecting sleeve 16 and two lifting rings 17. The upper end of the fixed shaft 15 is fixed on the U-shaped clamping seat 1. The connecting sleeve 16 is rotatably connected to the fixed shaft 15. Each lifting ring 17 is connected to one side of the connecting sleeve 16 through an adjusting screw 18, and the through hole 6 is arranged on the lifting ring 17.
[0034] The locking buckle 5 is composed of a fixed shaft 15, a connecting sleeve 16 and two lifting rings 17. The upper end of the fixed shaft 15 is fixedly installed on the U-shaped base 1, so that the entire locking buckle 5 can be firmly connected to the U-shaped base 1. The connecting sleeve 16 is rotatably connected to the fixed shaft 15. With the support of the fixed shaft 15, the connecting sleeve 16 can rotate freely 360 degrees. Each lifting ring 17 is connected to both sides of the connecting sleeve 16 through an adjusting screw 18, and a through hole 6 for the mother rope to pass through is opened on the lifting ring 17.
[0035] The advantages of this design are mainly reflected in the following aspects: the connecting sleeve 16 can rotate around the fixed axis 15 to adjust the position angle of the lifting ring 17, so as to facilitate the accurate passage of the mother rope through the through hole 6 and fix it. Each lifting ring 17 can adjust the connection distance with the connecting sleeve 16 by adjusting the screw 18, and change the distance between the two lifting rings 17 to better meet the site requirements. The design of the two lifting rings 17 disperses the load of the mother rope after passing through, and the connection is more firm and reliable.
[0036] In this embodiment, the limit shaft 7 is connected to the lifting ring 17 , and one end of the limit shaft 7 passes through the lifting ring 17 and is connected to a retaining spring 19 .
[0037] The key function of this design is to facilitate the rapid disassembly of the mother rope. Specifically, when the mother rope needs to be disassembled, it is only necessary to stretch and remove the retaining spring 19 from the groove of the lifting ring 17, and the limit shaft 7 can be easily removed from the lifting ring 17. Then the mother rope can be quickly pulled out from the opened lifting ring 17, which greatly simplifies the disassembly process. Compared with the traditional method that requires rotating multiple bolts or other fixings, the design of using the retaining spring 19 to lock the limit shaft 7 can be quickly disassembled with just a slight pull, which is easier and more efficient to operate.
[0038] In this embodiment, the surfaces of the U-shaped holder 1 and the fixing plate 2 are respectively coated with corrosion-resistant layers.
[0039] The device is used in outdoor environment for a long time and will inevitably be eroded by natural environment such as wind, rain, and sun exposure. Therefore, high requirements are placed on the corrosion resistance of the material. By specially coating a layer of corrosion-resistant coating on the surface of the U-shaped holder 1 and the fixing plate 2, not only can the service life of the entire device be extended, ensuring that the integrity and reliability of the structure can be maintained during long-term outdoor use, but more importantly, safety hazards such as breakage and falling off caused by corrosion can be avoided, fundamentally ensuring the personal safety of maintenance personnel.
[0040] The corrosion-resistant layer is generally made of zinc-rich paint, epoxy resin, polyurethane and other materials with excellent corrosion resistance. They can not only isolate the direct erosion of the metal by air and moisture, but also have excellent weather resistance, heat resistance and chemical corrosion resistance, and can effectively prevent the corrosion of metal by environmental factors such as sunlight, rain, salt spray, etc.
[0041] In this embodiment, a plurality of holes 20 for the anchor bolts to pass through are formed in the fixing plate 2 to fix the fixing plate 2 on the stack bridge deck.
[0042] As the base of the whole device, the fixing plate 2 needs to be firmly fixed on the stack bridge deck in a reliable manner to ensure that the whole device will not be displaced or fall off during use. Therefore, a plurality of holes 20 are formed in the fixing plate 2, and the anchor bolts are used to firmly anchor it in the concrete structure or steel beam of the stack bridge deck.
[0043] Through this anchoring method, there is no risk of loosening or falling off of the whole device on the stack bridge deck, which fundamentally ensures the personal safety of maintenance personnel. Even when the main rope swings violently or is under stress, the device can still maintain absolute stability.
[0044] The above is only the implementation mode of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present application by the same token.
