Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a reinforcement device for edge protection mesh. Background Technology

[0002] In bridge edge protection projects, traditional steel wire rope reinforcement requires manual tightening of the steel wire rope and manual locking with steel wire rope clips. The installation of a single mesh panel takes more than 15 minutes, resulting in high labor intensity for workers. In addition, existing steel wire rope clips are locked by friction, which are prone to loosening under wind load or impact, causing the mesh panel to deform or even fall off.

[0003] Therefore, it is necessary to propose a reinforcement device for edge protection mesh to solve the above problems. Utility Model Content

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A reinforcement device for edge protection netting, comprising a steel wire rope, and further comprising a locking mechanism and a locking buckle device disposed on the steel wire rope. The locking mechanism comprises a rectangular frame, with mounting holes on both the left and right side walls of the rectangular frame, and a common rotating shaft rotatably fitted into the two mounting holes; both ends of the rotating shaft extend out of the rectangular frame, and a limit block and a ratchet are respectively fixedly installed thereon, the ratchet being concentrically arranged with the rotating shaft, and a prism being concentrically fixedly installed on the outer side of the ratchet; one side of the ratchet is rotatably mounted... The device is equipped with a pawl, and a torsion spring I is provided between the pawl and the rectangular frame. The torsion spring I drives the pawl to engage with the ratchet. The front and rear side walls of the rectangular frame and the rotating shaft are all provided with wire holes. The three wire holes are arranged concentrically. One end of the steel wire rope passes through the three wire holes in sequence and is fixedly fitted with a collar. A ring platform is movably fitted on the steel wire rope between the collar and the rectangular frame, and the inner diameter of the ring platform is smaller than the outer diameter of the collar. A connecting ring is movably fitted on the outside of the collar. One end of the connecting ring is fixedly connected to the ring platform, and the other end is concentrically fixedly installed with an external threaded tube, which is threadedly connected to the rectangular frame.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1: This Example 1 provides a reinforcement device for edge protection mesh, which has a unique structure. Please refer to [link / reference]. Figure 1-7 As shown, the device includes a steel wire rope 1, a locking mechanism 2 and a locking device 3 mounted on the steel wire rope 1. The locking mechanism 2 includes a rectangular frame 21, with mounting holes on both the left and right side walls of the rectangular frame 21. The same rotating shaft 22 is rotatably mounted in the two mounting holes. Both ends of the rotating shaft 22 extend out of the rectangular frame 21 and are respectively fixedly mounted with a limit block 23 and a ratchet 24. The ratchet 24 is concentrically arranged with the rotating shaft 22, and a prism 25 is fixedly mounted concentrically on the outer side of the ratchet 24. A pawl 26 is rotatably mounted on one side of the ratchet 24. A torsion spring I 29 is provided between the pawl 26 and the rectangular frame 21, and the torsion spring I 29 drives the pawl 26 to engage with the ratchet 24.

[0024] The front and rear side walls of the rectangular frame 21 and the rotating shaft 22 are provided with wire holes. The three wire holes are arranged concentrically. One end of the steel wire rope 1 passes through the three wire holes in sequence and is fixedly fitted with a collar 211. A ring platform 214 is movably fitted on the steel wire rope 1 between the collar 211 and the rectangular frame 21, and the inner diameter of the ring platform 214 is smaller than the outer diameter of the collar 211. A connecting ring 213 is movably fitted on the outside of the collar 211. One end of the connecting ring 213 is fixedly connected to the ring platform 214, and the other end is concentrically fixedly installed with an external threaded tube 212, which is threadedly connected to the rectangular frame 21.

[0025] The rotating shaft 22, the limiting block 23, and the prism 25 are integrally formed. The prism 25 is a hexagonal prism. The ratchet 24 is welded to the rotating shaft 22. A through hole is opened on the side wall of the rectangular frame 21. A fixing rod 27 is rotatably fitted in the through hole. One end of the fixing rod 27 is welded to the pawl 26, and the other end is welded to the limiting plate 28. The torsion spring I 29 is sleeved on the fixing rod 27 between the limiting plate 28 and the rectangular frame 21. The two ends of the torsion spring I 29 are fixedly connected to the rectangular frame 21 and the limiting plate 28, respectively. The external threaded tube 212, the connecting ring 213, and the ring platform 214 are integrally formed. The outer diameter of the connecting ring 213 is larger than the outer diameter of the external threaded tube 212. An internal threaded tube 210 is welded to one side of the rectangular frame 21. The external threaded tube 212 and the internal threaded tube 210 are threadedly connected. The threaded connection facilitates the separation of one end of the wire rope 1 from the rectangular frame 21.

A baffle 33 is provided at the opening of the hook 31. One end of the baffle 33 is rotatably connected to the hook tail of the hook 31, and the other end is elastically abutting against the inner wall of the hook head of the hook 31. A pin 32 is rotatably installed on the inner side of the hook tail of the hook 31. The baffle 33 is rotatably connected to the hook 31 through the pin 32. A torsion spring II 34 is sleeved on the pin 32. The two ends of the torsion spring II 34 are fixedly connected to the hook 31 and the pin 32 respectively.

[0027] Working principle: When using this connecting device, first, the end of the wire rope 1 with the external threaded tube 212 is wrapped around two adjacent protective net panels. Then, the external threaded tube 212 and the internal threaded tube 210 are threaded together. Next, the locking device 3 is hung on the fixed beam plate rib. Then, the prism 25 is turned with a wrench. The prism 25 rotates, thereby tightening the wire rope 1, pulling and fixing the protective net panel, enhancing the connection and stability of the net panel, and improving the load-bearing capacity of the net panel.

[0028] Example 2: The difference between Example 2 and Example 1 is that the outside of 1 is wrapped with a nylon coating layer, which can prevent the steel wire rope 1 from becoming loose on the one hand, and prevent the steel wire rope from being corroded on the other hand, thus extending its service life.
