Description

Technical Field

[0001] This utility model relates to the field of wire rope connection technology, and in particular to a quick-replaceable wire rope connection device for steel beams. Background Technology

[0002] Steel beams are commonly used load-bearing components in building and bridge engineering. They are connected by steel wire ropes to achieve structural stability and adjustability. Wire rope connection devices are widely used in steel beams, especially in scenarios where frequent adjustments or replacements of the wire ropes are required, such as hoisting equipment and temporary support structures.

[0003] However, wire rope connection devices typically have the following shortcomings:

[0004] 1. Low replacement efficiency: Traditional devices require the disassembly of multiple parts when replacing wire ropes, which is cumbersome and time-consuming, and cannot meet the needs of rapid replacement.

[0005] 2. Poor stability: Existing devices lack an effective locking mechanism, and the wire rope is prone to loosening or slipping, especially under dynamic loads where reliability is insufficient. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a quick-replaceable wire rope connection device for steel beams, which overcomes the shortcomings of the prior art and effectively solves the problems of low replacement efficiency and poor stability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A quick-replaceable wire rope connection device for steel beams includes a housing. A winding roller is rotatably connected to the inner wall of the housing via a bearing. A knob is fixedly connected to the outer wall of one end of the winding roller. A ratchet is welded to the outer wall of the winding roller on one side of the knob. A shaft is welded to the outer wall of one side of the housing. A pawl is rotatably connected to the outer wall of the shaft. A torsion spring is fixedly connected between the pawl and the housing.

[0009] Preferably, the torsion spring is sleeved on the outside of the shaft rod, and the pawl is tightly attached to the outer wall of the ratchet.

[0010] Preferably, a limiting piece is welded to the bottom of the claw on one side of the outer wall of the box body.

[0011] Preferably, a sealing cap is fixedly connected to the outer wall of the top of the box by screws.

[0012] Preferably, guide tubes are installed through both outer walls of the box body, and steel wire ropes are inserted through the inner walls of the guide tubes.

[0013] Preferably, a rope-threading groove is provided through the outer wall of the winding roller, and one end of the wire rope is disposed on the inner wall of the rope-threading groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The steel beams in this design use a quick-change wire rope connection device. Through the integrated structure of the winding roller and the knob, users can easily rotate the winding roller to wind up and unwind the wire rope without disassembling other parts. Furthermore, the cooperation between the rope groove and the guide tube further simplifies the installation and replacement process of the wire rope and improves the operating efficiency.

[0016] 2. The steel beam in this design uses a quick-change wire rope connection device. The meshing mechanism of the ratchet and the pawl achieves one-way locking under the action of the torsion spring, preventing the wire rope from loosening due to the reverse rotation of the winding roller. In addition, the limiting plate ensures that the pawl is always in close contact with the ratchet, which enhances the load capacity of the device and is suitable for dynamic or high-intensity application scenarios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4Example 1: A quick-replaceable wire rope connection device for steel beams includes a box body 1. A winding roller 2 is rotatably connected to the inner wall of the box body 1 via a bearing, and a knob 3 is fixedly connected to the outer wall of one end of the winding roller 2.

[0024] Inside the housing 1, a winding roller 2 is installed via a bearing. A knob 3 is fixed to one end of the winding roller 2. The user can drive the winding roller 2 to rotate by rotating the knob 3, thereby winding the wire rope.

[0025] In this embodiment, the integrated structure of the winding roller 2 and the knob 3 allows the user to easily rotate the winding roller 2 to wind and unwind the wire rope without disassembling other parts. Furthermore, the cooperation between the rope groove 11 and the guide tube 10 further simplifies the installation and replacement process of the wire rope and improves operational efficiency.

[0026] In embodiment 2, a ratchet 4 is welded to the outer wall of the winding roller 2 on one side of the knob 3. A shaft 5 is welded to the outer wall of one side of the box body 1, and a pawl 6 is rotatably connected to the outer wall of the shaft 5. A torsion spring 7 is fixedly connected between the pawl 6 and the box body 1. The torsion spring 7 is sleeved on the outside of the shaft 5, and the pawl 6 is tightly attached to the outer wall of the ratchet 4. A limiting piece 8 is welded to the bottom of the pawl 6 on the outer wall of one side of the box body 1.

[0027] A ratchet 4 is welded to the side of the winding roller 2 near the knob 3. A spindle 5 is welded to the outside of the housing 1. A pawl 6 is connected to the housing 1 via the spindle 5 and is held tightly against the ratchet 4 by the force of the torsion spring 7. When the winding roller 2 rotates clockwise, the pawl 6 slides over the teeth of the ratchet 4; when it rotates counterclockwise, the pawl 6 engages the teeth of the ratchet 4 to prevent loosening. A limiting piece 8 is welded to the bottom of the pawl 6 to limit its swing range and ensure reliable engagement.

[0028] In this embodiment, the meshing mechanism between the ratchet 4 and the pawl 6 achieves one-way locking under the action of the torsion spring 7, preventing the wire rope from loosening due to the reverse rotation of the winding roller 2. Furthermore, the limiting piece 8 ensures that the pawl 6 is always in close contact with the ratchet 4, enhancing the load capacity of the device and making it suitable for dynamic or high-intensity application scenarios.

[0029] The top outer wall of the box 1 is fixed with a sealing cover 9 by screws.

[0030] The sealing cover 9 is fixed to the top of the box body 1 with screws, which can prevent dust or moisture from entering the interior.

[0031] Guide tubes 10 are installed through both outer walls of the box body 1, and steel wire ropes are inserted through the inner wall of the guide tubes 10. A rope-threading groove 11 is opened through the outer wall of the winding roller 2, and one end of the steel wire rope is set on the inner wall of the rope-threading groove 11.

[0032] A rope-threading groove 11 is provided on the outer wall of the winding roller 2. The end of the wire rope is embedded in the groove and fixed with screws to ensure a firm connection. The guide tubes 10 on both sides of the housing 1 are made of wear-resistant material to reduce wire rope friction and extend service life.

[0033] Working principle: First, the wire rope is inserted into the guide tube 10 on one side, and the end is embedded in the rope groove 11 of the winding roller 2 and fixed. Then, the knob 3 is rotated to drive the winding roller 2 to rotate and wind the wire rope. The ratchet 4 and the pawl 6 cooperate to ensure the length is locked. When the wire rope is under tension, the counterclockwise tendency of the winding roller 2 is stopped by the pawl 6. The torsion spring 7 enhances the meshing force between the pawl 6 and the ratchet 4 to prevent slippage. When replacing, the sealing cover 9 can be opened, and then the wire rope in the rope groove 11 can be loosened and the old wire rope can be pulled out to quickly replace the new rope. The main structure does not need to be disassembled throughout the process.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
