Description

Technical Field

[0001] This utility model relates to the field of wire rope technology, and in particular to a wire rope pretensioning device. Background Technology

[0002] The existing publication number (CN216549387U) discloses a pre-tensioning device for wire rope threading in crane hoists. This device can lower the clamping mechanism and the feed rope box to simulate the downward pulling of the wire rope by a worker, thereby applying a pre-tensioning force to the wound wire rope. Furthermore, the lateral movement of the guide rollers can drive the wire rope to move laterally, automating the winding of the wire rope on the hoist without manual assistance. However, when pulling the wire rope and driving its lateral displacement, significant friction occurs between the wire rope and the inner wall of the rope inlet. This friction not only causes wear on the wire rope but also results in energy loss, affecting the efficiency and service life of the pre-tensioning device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Existing pretensioning devices generate significant friction between the wire rope and the inner wall of the rope inlet when pulling the wire rope and causing it to move laterally. This friction not only causes wear on the wire rope but also results in energy loss, affecting the efficiency and service life of the pretensioning device.

[0022] To address the deficiencies in the use of the aforementioned pre-tightening device, please refer to [link / reference needed]. Figures 1-5This utility model provides a wire rope pre-tensioning device that lubricates the wire rope at the rope inlet 4, reducing friction between the wire rope and the inner wall of the rope inlet 4, and thus reducing wear on the wire rope. The pre-tensioning device uses a support 1 as a base. A pressing mechanism 2 and a rope-laying box 3 are slidably mounted on the side of the support 1. The rope-laying box 3 has a rope inlet 4 on its side. A lifting mechanism is installed inside the support 1 to drive the pressing mechanism 2 and the rope-laying box 3 to slide up and down for pulling the wire rope. This is prior art and will not be described in detail here. A support 5 is slidably connected inside the rope-laying box 3, and a guide roller 6 is rotatably mounted on the support 5. The wire rope enters the rope-laying box 3 from the rope inlet 4, passes through the guide roller 6, and then exits from the rope-laying box 3. An oil supply tank 7 is slidably connected to the side of the rope-laying box 3, and the oil supply tank 7 contains lubricating oil. A lubricating element 8 is provided on the side of the rope box 3. The oil supply tank 7, the lubricating element 8 and the rope inlet 4 are located on the same side of the rope box 3, and the lubricating element 8 is located between the rope inlet 4 and the oil supply tank 7. One end of the rope box 3 is also provided with a driving element 9 for driving the guide roller 6 and the oil supply tank 7 to slide back and forth. The driving element 9 can drive the guide roller 6 to move while driving the oil supply tank 7 to move. The movement of the guide roller 6 causes the wire rope to move laterally. The movement of the oil supply tank 7 can add lubricating oil to the lubricating element 8. When the wire rope passes through the rope inlet 4 and moves along the rope inlet 4, the lubricating element 8 can lubricate the wire rope and reduce the friction on the surface of the wire rope.

[0023] To achieve the lubrication effect of the lubricating component 8 on the wire rope, the lubricating component 8 is designed as a leak-proof frame 81 installed on the side of the rope box 3. A lubricating sponge 82 is fixedly connected inside the leak-proof frame 81, and a pair of T-shaped blocks 83 are fixedly connected to one side of the leak-proof frame 81. The rope box 3 has T-shaped grooves for the T-shaped blocks 83 to be inserted. The top and bottom heights of the lubricating sponge 82 are lower than the top and bottom heights of the leak-proof frame 81, respectively. The leak-proof frame 81 can prevent the lubricating oil dripping from the oil supply tank 7 from overflowing, ensuring that the lubricating sponge 82 absorbs the lubricating oil. The lubricating sponge 82 also has multiple evenly distributed oil distribution holes 84. The lubricating oil can directly enter the interior of the lubricating sponge 82 through the oil distribution holes 84, accelerating the absorption of the lubricating oil by the lubricating sponge 82. When the wire rope moves at the rope inlet 4, it will come into contact with the lubricating sponge 82. As the wire rope moves, the lubricating sponge 82 can wipe the wire rope and apply the lubricating oil to the wire rope, thus achieving lubrication of the wire rope.

[0024] After prolonged use, the lubricating sponge 82 will age and wear out. Therefore, it is necessary to facilitate the replacement of the lubricating sponge 82. A fixing member 10 for fixing the T-shaped block 83 is provided on the outer wall of the rope box 3. The fixing member 10 includes a corner rod 101 fixedly installed at the corner of the rope box 3 and a corner plate 102 slidably installed at the corner of the rope box 3. Insert rods 103 are rotatably installed at both ends of the corner rod 101. Protrusions are provided on both sides of the insert rods 103. The corner plate 102 has slots 104 for inserting the insert rods 103, and a circular groove 105 communicating with the slots 104 is provided inside the corner plate 102. After inserting the T-shaped block 83 into the T-shaped groove, the corner plate 102 can be slid upwards. The insertion rod 103 is inserted into the slot 104 and the circular groove 105. Then, the insertion rod 103 is rotated to offset it from the slot 104. The protrusions on both sides of the insertion rod 103 are fixed in the circular groove 105, restricting the downward movement of the corner plate 102. The corner plate 102 can block the T-slot, thereby ensuring the stability of the lubricating sponge 82 during the lubrication process and preventing it from falling off automatically. When the lubricating sponge 82 needs to be replaced, simply rotate the insertion rod 103 until it aligns with the slot 104. The corner plate 102 can then slide down under its own weight. Subsequently, the leak-proof frame 81 can be slid off the rope box 3 to facilitate the replacement of the new lubricating component 8 and continue the lubrication operation, ensuring the lubrication effect of the equipment on the wire rope.

[0025] To achieve synchronous sliding of the support 5 and the oil supply tank 7, a lead screw 91 rotatably installed inside the rope box 3 and a lead screw 92 rotatably installed on the side of the rope box 3 are provided. The rope inlet 4 is threaded to the outside of the lead screw 91, and the oil supply tank 7 is threaded to the outside of the lead screw 92. The ends of both the lead screw 91 and the lead screw 92 are fixedly connected to synchronous pulleys 93. A synchronous belt 94 is installed on the outside of the two synchronous pulleys 93. A servo motor 95 is fixedly installed on one side of the rope box 3, which drives one of the synchronous pulleys 93 to rotate. The servo motor 95 drives the lead screw 91 to rotate, and the two synchronous pulleys 93 and the synchronous belt 94 drive the lead screw 92 to rotate, thereby driving the guide roller 6 and the oil supply tank 7 to slide synchronously. The oil supply tank 7 can add lubricating oil to the lubricating sponge 82 in a movable manner to ensure the uniformity of the lubricating oil in the lubricating sponge 82.

[0026] Reference Figure 3 As shown, the bottom of the oil supply tank 7 is equipped with a discharge pipe 71, which is aligned with the lubricating sponge 82. A valve is provided on the side of the oil supply tank 7 to control the opening and closing of the discharge pipe 71. When the equipment is in operation, the discharge pipe 71 is in the open state, which can continuously add lubricating oil to the lubricating sponge 82 to ensure sufficient lubricating oil in the lubricating sponge 82. The oil supply tank 7 is also equipped with an oil filling hole for easy replenishment of lubricating oil. When the equipment is not in operation, the discharge pipe 71 can be closed to avoid wasting lubricating oil.

[0027] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
