Description

Technical Field

[0001] This utility model relates to the technical field of wire rope production, specifically to a tightening device for wire rope production. Background Technology

[0002] A wire rope is a helical bundle of steel wires twisted together according to specific rules, meeting requirements for mechanical properties and geometric dimensions. It consists of steel wires, a core, and lubricant. The process involves first twisting multiple layers of steel wires into strands, then winding a certain number of strands around the core to form a helical shape. In material handling machinery, it is used for lifting, traction, tensioning, and load-bearing. Wire ropes are characterized by high strength, light weight, smooth operation, and resistance to sudden breakage, ensuring reliable operation.

[0003] During the production and processing of wire ropes, workers use wire rope tightening devices to clamp both ends of the wire rope, thus tightening it to assist production personnel in processing the wire rope. Existing wire rope tightening devices, such as the one with patent publication number CN222557323U, have wire rope ends that pass through the groove and under the pressure column. A driving component drives the pressure column to rotate on the shaft, causing the pressure column to tend to be vertical, thereby pressing the wire rope below it. In addition, the L-shaped structure of the pressure column increases the contact area when the pressure column presses the wire rope, thereby improving the tightness.

[0004] However, the handle used for adjusting the clamping requires a great deal of turning force to meet the clamping requirements, making it inconvenient to operate and impractical. Utility Model Content

The double-threaded rod 2 is rotatably mounted on the inner center of the slide 1. The front end of the double-threaded rod 2 is connected to the rear center of the screw pan 3. The inner center of the slider 4 is connected to the outer side of the internal threaded sleeve 5. The inner wall of the internal threaded sleeve 5 is connected to the double-threaded rod 2. The outer wall is screwed together. Two sets of sliders 4 are symmetrically slidably arranged in the slide frame 1. The top side of the slider 4 is connected to the bottom side of the bottom pressure plate 7 via the bracket 6. The top left and right sides of the bottom pressure plate 7 are respectively connected to the bottom side of a set of guide frames 8. The top sides of the two sets of guide frames 8 are connected to the bottom sides of the internal thread top plate 9. The inner wall of the internal thread top plate 9 is screwed together with the outer wall of the pressure screw 10. The bottom side of the pressure screw 10 is rotatably connected to the middle of the top side of the pressure contact frame 12. A set of sliding sleeves 11 are respectively connected to the left and right sides of the pressure contact frame 12. The inner wall of sleeve 11 is vertically slidably connected to the outer wall of the corresponding guide frame 8. The top side of the clamping screw 10 is connected to the middle of the bottom side of the sliding sleeve 13. A long handle 14 is slidably installed inside the sliding sleeve 13. The steel wire rope to be tightened is passed through the guide frame 8 at the top of the two sets of bottom clamping plates 7 and the inner side of the clamping contact frame 12, and then the screw plate 3 is turned to make the bidirectional threaded rod 2 rotate. The bidirectional threaded rod 2 is screwed into two sets of internal threaded sleeves 5. The internal threaded sleeves 5 connect to the slider 4, which moves towards or away from each other inside the sliding frame 1. Then, it is connected to the bracket 6. The bottom clamping plate 7 moves accordingly to adapt to the clamping position of the wire rope. Then, the long handle 14 slides in the sliding sleeve 13, so that one side extends to increase the torque. The long handle 14 on the protruding side is screwed, and the clamping screw 10 is connected to the sliding sleeve 13 to rotate. The clamping screw 10 is screwed into the internal thread top plate 9, which drives the clamping contact frame 12 to slide downward under the constraint of the guide frame 8 through the two sets of sliding sleeves 11. Thus, the clamping contact frame 12 acts on the wire rope to clamp it, and then the screw pan 3 is turned to tighten the clamped wire rope.

[0027] It also includes a contact wheel 15, a top frame 16, a connecting spring 17, and an anti-slip pressure plate 18. The outer front part of the bidirectional threaded rod 2 inside the slide 1 is connected to the inner side of the contact wheel 15. The front top of the slide 1 is connected to the bottom side of the top frame 16. The top inside of the top frame 16 is connected to the top side of the anti-slip pressure plate 18 via the connecting spring 17. Under the connection of the top frame 16, the connecting spring 17 acts on the anti-slip pressure plate 18 to push it downward, and acts on the contact wheel 15 to generate static friction force to tighten it and prevent it from rotating.

[0028] It also includes a second sliding sleeve 19, a sliding rod 20, and a pull plate 21. The inner side of the top of the top frame 16 is connected to the outer side of the second sliding sleeve 19. The inner wall of the second sliding sleeve 19 is vertically slidably connected to the outer wall of the sliding rod 20. The top side of the sliding rod 20 is connected to the middle of the bottom side of the pull plate 21. The bottom side of the sliding rod 20 is connected to the middle of the top side of the anti-slip pressure plate 18. By pulling the pull plate 21, the sliding rod 20 can slide upward on the inner side of the second sliding sleeve 19, the anti-slip pressure plate 18 moves upward, and the contact wheel 15 is released, making it convenient to turn the screw pan 3 for adjustment.

[0029] It also includes grip sleeves 22, with the outer sides of the left and right sides of the long handlebar 14 respectively connected to the inner sides of a set of grip sleeves 22; the grip sleeves 22 facilitate the gripping and operation of this part of the long handlebar 14, preventing slippage, and the sliding sleeve 11 can limit this side of the long handlebar 14 to prevent it from coming off.

[0030] It also includes an indicator head 23 and a scale bar 24. The top left side of the slide 1 is connected to the bottom side of the scale bar 24. Each set of sliders 4 has an indicator head 23 connected to the top left middle side. The indicator head 23 is movably set outside the scale bar 24. When the slider 4 moves, the indicator head 23 can move accordingly. The scale indicated by the indicator head 23 outside the scale bar 24 makes it easy to accurately judge the tension of the wire rope and improves convenience.

[0031] It also includes an oil injection nozzle 25, with the outer side of the middle of the top of each set of internal threaded sleeves 5 connected to the bottom side of an oil injection nozzle 25; oil can be injected into the inner wall of the internal threaded sleeve 5 through the oil injection nozzle 25 to facilitate its movement and lubrication with the bidirectional threaded rod 2.

[0032] It also includes an oil filling cap 26, and the outer side of the oil filling nozzle 25 and the inner side of the oil filling cap 26 can be detachably installed; after the oil filling cap 26 is installed on the outer side of the oil filling nozzle 25, the inside of the oil filling nozzle 25 can be sealed and protected, improving reliability.

[0033] In summary, when using the wire rope tightening device, the wire rope to be tightened is passed through the guide frame 8 at the top of the two sets of bottom clamping plates 7 and the inner side of the clamping contact frame 12. By pulling the pull plate 21, the slide rod 20 can slide upward on the inner side of the sliding sleeve 19, and the anti-slip pressure plate 18 moves upward, loosening the contact wheel 15. Then, the screwing disc 3 is turned to rotate the bidirectional threaded rod 2. The bidirectional threaded rod 2 is screwed into the two sets of internal threaded sleeves 5. The internal threaded sleeves 5 connect the slider 4 to move towards or away from each other on the inner side of the slide frame 1. Then, the bottom clamping plate 7 moves accordingly through the bracket 6. When the slider 4 moves, the indicator head 23 moves accordingly. The indication scale on the outer side of the scale bar 24 of the indicator head 23 makes it easy to accurately judge the tightening status of the wire rope and adapt it to the clamping position of the wire rope. Finally, the long handle 14 passes through the sliding sleeve 13. The inner sliding mechanism extends one side to increase torque. The long handle 14, protruding from the grip sleeve 22, is held and screwed through the sliding sleeve 13 to rotate the clamping screw 10. The clamping screw 10 is screwed into the internal threaded top plate 9, causing the clamping contact frame 12 to slide downwards through two sets of sliding sleeves 11 under the constraint of the guide frame 8. Thus, the clamping contact frame 12 acts on the wire rope to clamp it. Then, the screw pan 3 is turned to tighten the clamped wire rope. Under the connection of the top frame 16, the connecting spring 17 acts on the anti-slip pressure plate 18 to push it downwards, which in turn acts on the contact wheel 15 to generate static friction to clamp it and prevent it from rotating. In addition, oil can be injected into the inner wall of the internal threaded sleeve 5 through the oil injection nozzle 25 to facilitate its movement and lubrication with the bidirectional threaded rod 2. After installing the oil injection cap 26 on the outside of the oil injection nozzle 25, the inside of the oil injection nozzle 25 can be sealed and protected to improve reliability.
