Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an automatic adjustment device for wire rope tension. Background Technology

[0002] Adjusting the tension of wire ropes ensures stable operation under load. Excessive tension prevents slippage, rope jumping, or vibration, reducing wear and safety hazards; excessive tension causes stress concentration, lowering the risk of breakage and extending service life. Proper tension ensures precise equipment operation, improves transmission efficiency, balances the load on each rope segment, and prevents overloading of any single rope. This is a crucial factor in ensuring the safe, efficient, and stable operation of mechanical systems, directly impacting equipment performance and operational safety.

[0003] The wire rope tension adjustment device dynamically adjusts the wire rope tension to compensate for tension fluctuations caused by rope expansion and contraction, wear, or load changes. This ensures uniform and stable tension, preventing slippage due to excessive looseness and breakage due to excessive tightness, extending service life, and guaranteeing equipment safety and precision. It is suitable for hoisting systems of cranes and elevators, cableway transport equipment, traction mechanisms of port machinery, tensioning equipment in construction, and mining hoists—scenarios requiring multiple ropes to bear force simultaneously or experiencing high-frequency load changes. It is particularly indispensable in high-altitude and heavy-duty equipment.

[0004] In existing technologies, some wire rope tension adjustment devices are generally designed to be integrated with the traction mechanism or lifting mechanism. This means that when the wire rope tension adjustment device malfunctions, a lot of time needs to be spent disassembling the device for inspection or replacement. This greatly prolongs the maintenance time and reduces work efficiency. Therefore, an automatic wire rope tension adjustment device is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an automatic wire rope tension adjustment device, including a mounting plate 1. The mounting plate 1 is used to support all the components of the entire device and provide a mounting base. Two mounting mechanisms 2 are installed on the top of the mounting plate 1. The two mounting mechanisms 2 are symmetrically distributed to ensure the stability of the installation of the fixing box 5. The fixing box 5 is detachably connected to the top of the mounting plate 1. The detachable connection facilitates the disassembly and maintenance of the fixing box 5. A tension adjustment component 3 is installed inside the fixing box 5. The tension adjustment component 3 is used to realize the automatic adjustment of the wire rope tension.

[0034] Mounting blocks 4 are fixedly connected to both sides of the fixed box 5. The mounting blocks 4 cooperate with the mounting mechanism 2 to fix the fixed box 5. The mounting mechanism 2 includes a cam 21. The cam 21 can push the sliding block 252 to move by rotating. The inner wall of the cam 21 is rotatably connected to the top of the mounting plate 1, so that the cam 21 can rotate around the mounting plate 1. A rotating column 22 is fixedly connected to the inner wall of the cam 21. The rotating column 22 is used to transmit the rotational torque of the control rod 24. The bottom of the rotating column 22 is rotatably connected to the inside of the mounting plate 1 to ensure the stability of the rotating column 22 when rotating. A fixing block 26 is fixedly connected to the top of the mounting plate 1. The fixing block 26 provides installation support for the fixing component 25 and the control rod 24. The fixing component 25 is installed on the outer wall of the fixing block 26. The fixing component 25 is used to realize the directional sliding of the sliding block 252 and the movement of the limiting column 253.

[0035] The fixing component 25 includes two sliding rods 251, which are arranged in parallel to ensure the smooth sliding of the sliding block 252. One end of each sliding rod 251 is fixedly connected to the outer wall of the fixing block 26 to fix the position of the sliding rod 251. The outer wall of the sliding rod 251 is slidably connected to the sliding block 252, which can slide along the axial direction of the sliding rod 251. The outer wall of the sliding block 252 is fixedly connected to a limit post 253, which drives the limit post 253 to move synchronously. The other end of each sliding rod 251 is fixedly connected to two fixing plates 254, which are used to fix the other end of the sliding rod 251 to prevent the sliding block 252 from detaching from the sliding rod 251. The bottom of the two fixing plates 254 is fixedly connected to the top of the mounting plate 1 to enhance the stability of the limit post 253.

[0036] A control rod 24 is fixedly connected to the outer wall of the rotating column 22. The rotating column 22 is rotated by moving the control rod 24. A fixing screw 23 is threadedly connected to the inner wall of the control rod 24. The fixing screw 23 is used to fix the control rod 24 to the fixing block 26. The outer wall of the fixing screw 23 is threadedly connected to the inner wall of the fixing block 26 to fix the control rod 24 to the fixing block 26. The outer wall of the cam 21 is in contact with the outer wall of the fixing block 26. The fixing block 26 provides certain support and limit for the cam 21. The outer side of the cam 21 is in contact with the outer wall of the sliding block 252 so that the sliding block 252 can be pushed to slide when the cam 21 rotates. The outer wall of the limiting column 253 is detachably connected to the inner wall of the mounting block 4. The installation and fixation of the fixing box 5 are achieved through the cooperation of the limiting column 253 and the mounting block 4.

[0037] Reference Figure 2 and Figure 4 The tension adjustment assembly 3 includes a cylinder 31, which provides power for tension adjustment. A control plate 32 is fixedly connected to the drive end of the cylinder 31. The cylinder 31 drives the control plate 32 to slide within the fixed box 5. Two rotating rods 33 are rotatably connected to the inner wall of the control plate 32. When the control plate 32 slides, it drives the rotating rods 33 to rotate. The other ends of the two rotating rods 33 are rotatably connected to a transmission rod 34. The rotation of the rotating rods 33 drives the transmission rod 34 to move. The other end of the transmission rod 34 is rotatably connected to a connecting rod 37. The transmission rod 34 drives the connecting rod 37 to move. The two sides of the connecting rod 37 are slidably connected to the inner wall of the fixed box 5, so that the connecting rod 37 slides directionally along the inner wall of the fixed box 5.

[0038] A pulley 38 is fixedly connected to the outer wall of the connecting rod 37. The pulley 38 is used to support and guide the steel wire rope. A wheel slide plate 36 is rotatably connected to the outside of the connecting rod 37. The wheel slide plate 36 provides mounting support for the pulley 38. One end of the transmission rod 34 is fixedly connected to the outside of the wheel slide plate 36. The transmission rod 34 drives the wheel slide plate 36 to move synchronously. A pitch groove 35 is provided on the inner wall of the fixed box 5. The pitch groove 35 provides a path for the sliding of the connecting rod 37 and restricts its movement direction. Both ends of the connecting rod 37 are slidably connected to the inner wall of the pitch groove 35, so that the connecting rod 37 slides along the pitch groove 35, thereby driving the pulley 38 to adjust its position.

[0039] Working principle: When the fixing box 5 needs to be installed on the top of the mounting plate 1, the bottom of the fixing box 5 is placed on the top of the mounting plate 1. Then, the control lever 24 is moved, which drives the rotating column 22 to rotate. The rotation of the rotating column 22 drives the cam 21 to rotate. The rotation of the cam 21 drives the sliding block 252 to slide on the top of the mounting plate 1. During this process, the sliding rod 251 acts as a limit to the sliding of the sliding block 252. The sliding of the sliding block 252 drives the limit post 253 to move, so that the limit post 253 slides into the interior of the mounting block 4, thereby fixing the fixing box 5 on the top of the mounting plate 1. Then, the control lever 24 is fixed to the top of the fixing block 26 by the fixing screw 23, thereby fixing the cam 21 and preventing the cam 21 from rotating accidentally and causing the limit post 253 to fall out.

[0040] When the wire rope tension needs to be adjusted via the wheel slide plate 36, the cylinder 31 is activated. The activation of the cylinder 31 causes the control plate 32 to slide against the inner wall of the fixed box 5. The sliding of the control plate 32 causes the rotating rod 33 to rotate. The rotation of the rotating rod 33 causes the transmission rod 34 to move the wheel slide plate 36 and the internal pulley 38 to move laterally within the fixed box 5. At this time, the connecting rod 37 slides within the variable pitch groove 35 inside the fixed box 5, thereby moving the pulley 38 to either the sides or inwards, thus controlling the wire rope tension. Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
