Description

Technical Field

[0001] This utility model relates to the field of winch equipment technology, and in particular to a winch tail rope guide groove anti-jumping structure. Background Technology

[0002] In the daily use of winch equipment, the stable guidance of the tail rope is a crucial factor in ensuring the normal operation of the equipment and operational safety. However, due to various complex factors, there are many potential hazards when the tail rope runs within the guide groove. For example, the tension of the tail rope fluctuates frequently due to changes in load and the dynamic swaying of the lifted object; during the operation of the winch itself, the operation of mechanical parts and the vibration from the contact between the equipment and the ground are transmitted to the guide groove, causing vibration of the tail rope; in addition, if there is a deviation in the installation angle of the winch or an improper initial winding method of the tail rope, the movement trajectory of the tail rope may deviate. The combined effect of these adverse factors makes the tail rope extremely prone to jumping out of the guide groove.

[0003] When existing technical solutions are used,

[0004] (1) When the winch vibrates or the tension of the tail rope fluctuates greatly during operation, the tail rope is very likely to jump and deviate in the guide groove. Due to the lack of effective constraint and buffer mechanism, the tail rope often jumps out of the guide groove, which leads to the interruption of winch operation and may even cause safety accidents in severe cases.

[0005] (2) The structure cannot adjust the tension of the tail rope according to the real-time state of the tail rope, making it difficult for the tail rope to maintain a stable operating state under different working conditions, reducing the efficiency and reliability of the winch operation, and making it difficult to maintain a synchronous rotation state, which is prone to loosening.

[0006] To address the above problems, this utility model provides a winch tail rope guide groove anti-jumping structure. Utility Model Content

[0007] The purpose of this invention is to solve the problems in the prior art where the tail rope easily jumps out of the guide groove and the tail rope tension cannot be effectively adjusted, and to propose a winch tail rope guide groove anti-jumping structure.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a winch tail rope guide groove anti-jumping structure, comprising a support frame, a guide groove mechanism, a power transmission mechanism, and a connecting and fixing mechanism. An anti-slip base is fixedly connected to the bottom of the support frame. There are two support frames. Support frames are fixedly connected to both sides of the power transmission mechanism. The guide groove mechanism is threadedly connected to the outer surface of the power transmission mechanism. The connecting and fixing mechanism is rotatably connected to the inside of the support frame. The guide groove mechanism includes a sliding plate threadedly connected to the outer surface of the support frame. A U-shaped groove is formed at the top of the sliding plate. An elastic support component is fixedly connected inside the U-shaped groove. A limiting flange is fixedly connected to the top of the U-shaped groove. The limiting flanges are symmetrically arranged on both sides of the U-shaped groove. A tension adjustment component is fixedly connected to the outer surface of the sliding plate.

[0009] Furthermore, the elastic support assembly includes a damper fixedly connected inside the U-shaped groove, a shock-absorbing telescopic spring sleeved on the outer surface of the damper, and an arc-shaped elastic support plate fixedly connected to the top of the damper and the shock-absorbing telescopic spring. The shock-absorbing telescopic spring and the arc-shaped elastic support plate are evenly and equidistantly arranged inside the U-shaped groove.

[0010] Furthermore, the tension adjustment assembly includes a connecting column fixedly connected to the outer surface of the sliding plate, a fixing ring fixedly connected to both sides of the connecting column, a limit spring fixedly connected inside the fixing ring, a positioning plate fixedly connected to the outer surface of the limit spring, and the positioning plate and the limit spring being symmetrically arranged inside the fixing ring.

[0011] Furthermore, the power transmission mechanism includes a fixed plate fixedly connected to the top of the support frame, a servo motor fixedly connected inside the fixed plate, a main rotating shaft fixedly connected to the output end of the servo motor, and a rotating belt rotatably connected to the outer surface of the main rotating shaft.

[0012] Furthermore, the rotating belt is internally rotatably connected to a rotating shaft, a threaded rod is fixedly connected to one side of the rotating shaft, the sliding plate is threadedly connected to the outer surface of the threaded rod, a connecting rod is rotatably connected to one side of the rotating shaft, a bearing is rotatably connected to the outer surface of the connecting rod, and the outer surface of the bearing is fitted into the bottom of the support frame.

[0013] Furthermore, the connecting and fixing mechanism includes a fixing ring fixedly connected to the outer surface of the main rotating shaft, an adjuster being threadedly connected to the outer surface of the fixing ring, and a roller positioner being rotatably connected to the bottom of the adjuster.

[0014] Furthermore, the roller positioner and the adjuster are arranged at four equal intervals on the outer surface of the fixed ring, and a tail rope rotator is engaged inside the roller positioner.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, by setting up a shock-absorbing telescopic spring, an arc-shaped elastic support plate, and a limiting flange, when the tail rope is running in the guide groove, the elastic support assembly composed of the shock-absorbing telescopic spring and the damper can effectively buffer the jumping of the tail rope caused by vibration or tension changes. The arc-shaped elastic support plate increases the contact area with the tail rope, making the support force more uniform, maintaining the center position of the tail rope in the groove, and reducing the amplitude of the tail rope jumping up and down. At the same time, the limiting flange can restrict the lateral movement of the tail rope, preventing it from jumping out from the side of the guide groove, and always maintaining the stable operation of the tail rope in the guide groove, greatly reducing the risk of the tail rope jumping out of the guide groove.

[0017] 2. In this utility model, through the setting of the main rotating shaft, the limiting spring, and the roller positioner, the servo motor drives the main rotating shaft to rotate, and the rotating belt drives the driven shaft and the threaded rod to rotate, thereby realizing the precise position adjustment of the guide groove mechanism. It can flexibly adapt to the guiding needs of the tail rope under different working conditions. At the same time, the positioning plate can be finely adjusted according to the actual tension of the tail rope under the action of the limiting spring. The real-time and precise tension adjustment function ensures that the tail rope can maintain a stable operating state under different working conditions, effectively improving the efficiency and reliability of the winch operation. In addition, the roller positioner can accurately position and fix the tail rope rotor, so that the tail rope remains stable during rotation, ensuring the synchronous rotation of each component and avoiding the jumping and loosening phenomena caused by asynchronous rotation.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a winch tail rope guide groove anti-jumping structure, including a winch tail rope guide groove anti-jumping structure, including a support frame 1, a guide groove mechanism 2, a power transmission mechanism 3 and a connecting and fixing mechanism 4. The bottom of the support frame 1 is fixedly connected to an anti-slip base 5. There are two support frames 1. The two sides of the power transmission mechanism 3 are fixedly connected to the support frames 1. The guide groove mechanism 2 is threaded to the outer surface of the power transmission mechanism 3. The connecting and fixing mechanism 4 is rotatably connected to the inside of the support frame 1.

[0027] The specific configuration and function of its guide groove mechanism 2, power transmission mechanism 3 and connecting and fixing mechanism 4 will be explained below.

[0028] In this embodiment: the guide groove mechanism 2 includes a sliding plate 21 threaded to the outer surface of the support frame 1. A U-shaped groove 22 is provided on the top of the sliding plate 21. An elastic support component 23 is fixedly connected inside the U-shaped groove 22. A limiting flange 24 is fixedly connected to the top of the U-shaped groove 22. The limiting flange 24 is symmetrically arranged on both sides of the U-shaped groove 22. A tension adjustment component 25 is fixedly connected to the outer surface of the sliding plate 21.

[0029] The effects achieved by the above components are as follows: the smooth inner wall of the U-shaped groove 22 can reduce the friction between the tail rope and the groove body, reduce the wear of the tail rope, and the sliding plate 21 can slide smoothly up and down along the outer surface of the support frame 1. The sliding stroke is adapted to the working range of the winch equipment and meets the different guiding requirements of the tail rope.

[0030] Specifically, the elastic support assembly 23 includes a damper 231 fixedly connected inside the U-shaped groove 22. A shock-absorbing telescopic spring 232 is sleeved on the outer surface of the damper 231. An arc-shaped elastic support plate 233 is fixedly connected to the top of the damper 231 and the shock-absorbing telescopic spring 232. The shock-absorbing telescopic spring 232 and the arc-shaped elastic support plate 233 are evenly and equidistantly arranged inside the U-shaped groove 22.

[0031] The effects achieved by the above components are as follows: the damping force can be automatically adjusted according to the amplitude and frequency of the tail rope jumping, the energy generated by the tail rope jumping can be quickly attenuated, and the tail rope vibration can be suppressed. The shock-absorbing telescopic spring 232 can be smoothly extended and retracted under the action of the damper 231, providing continuous and stable elastic support force for the tail rope. The arc-shaped elastic support plate 233 is made of rubber composite material with good flexibility and wear resistance. Its arc shape fits the outer contour of the tail rope, increasing the contact area with the tail rope.

[0032] Specifically, the tension adjustment assembly 25 includes a connecting post 251 fixedly connected to the outer surface of the sliding plate 21, a fixing ring 252 fixedly connected to both sides of the connecting post 251, a limit spring 253 fixedly connected inside the fixing ring 252, a positioning plate 254 fixedly connected to the outer surface of the limit spring 253, and the positioning plate 254 and the limit spring 253 are symmetrically arranged inside the fixing ring 252.

[0033] The effect achieved by the above components is as follows: the positioning plate 254 moves under the action of the limiting spring 253 to accurately adjust the tension of the tail rope. The positioning plate 254 and the limiting spring 253 are symmetrically arranged in the fixing ring 252 to ensure that the tension on both sides of the tail rope is adjusted evenly, so that the tail rope is balanced under force and avoids deviation and jumping due to excessive tension on one side.

[0034] Specifically, the power transmission mechanism 3 includes a fixed plate 31 fixedly connected to the top of the support frame 1. A servo motor 32 is fixedly connected inside the fixed plate 31. A main rotating shaft 33 is fixedly connected to the output end of the servo motor 32. A rotating belt 34 is rotatably connected to the outer surface of the main rotating shaft 33.

[0035] The effect achieved by the above components is as follows: the outer surface of the main rotating shaft 33 is rotatably connected to the rotating belt 34, which is a high-strength, wear-resistant rubber belt. Through it, the efficient transmission and flexible conversion of power can be achieved, and the speed and torque of power transmission can be adjusted according to different working requirements.

[0036] Specifically, the rotating belt 34 is internally rotatably connected to a rotating shaft 35, and a threaded rod 36 is fixedly connected to one side of the rotating shaft 35. The sliding plate 21 is threadedly connected to the outer surface of the threaded rod 36. A connecting rod 37 is rotatably connected to one side of the rotating shaft 35, and a bearing 38 is rotatably connected to the outer surface of the connecting rod 37. The outer surface of the bearing 38 is fitted into the bottom of the support frame 1.

[0037] The above components achieve the following effects: the connecting rod 37, which is connected to the other side of the rotating shaft 35, serves to connect and support the rotating shaft 35, ensuring stable rotation of the rotating shaft 35; the bearing 38, which is rotatably connected to the outer surface of the connecting rod 37, effectively reduces the friction when the connecting rod 37 rotates, thereby improving the power transmission efficiency.

[0038] Specifically, the connecting and fixing mechanism 4 includes a fixing ring 41 fixedly connected to the outer surface of the main rotating shaft 33, an adjuster 42 threadedly connected to the outer surface of the fixing ring 41, and a roller positioner 43 rotatably connected to the bottom of the adjuster 42.

[0039] The effect achieved by the above components is as follows: the outer surface of the fixed ring 41 is threaded to connect the adjuster 42. The adjuster 42 is a metal adjustment knob with external threads. By rotating the adjuster 42, its position on the fixed ring 41 can be precisely adjusted, thereby achieving fine adjustment of the tail rope rotator 44.

[0040] Specifically, the roller positioner 43 and the adjuster 42 are set at four equal intervals on the outer surface of the fixed ring 41, and the tail rope rotator 44 is snapped into the inside of the roller positioner 43.

[0041] The effect achieved by the above components is that the uniform distribution ensures that the fixing and adjustment of components such as the tail rope rotator 44 are uniform and stable, avoiding deformation or poor rotation of components due to uneven force.

[0042] Working principle: When the winch is working, the servo motor 32 starts and outputs rotational power to the main rotating shaft 33. The main rotating shaft 33 drives the secondary rotating shaft 35 to rotate through the rotating belt 34. The rotation of the secondary rotating shaft 35 causes the threaded rod 36 connected to it to rotate synchronously. The rotation of the threaded rod 36 drives the sliding plate 21 to move left and right along the outer surface of the support frame 1, thereby adjusting the position of the guide groove mechanism 2 to adapt to the guiding requirements of the tail rope under different working conditions.

[0043] The tail rope is placed in the U-shaped groove 22. During operation, if the tail rope jumps due to winch vibration or changes in tail rope tension, the elastic support component 23 will play a role. The damper 231 will quickly attenuate the jumping energy, the shock-absorbing telescopic spring 232 will provide elastic support force, and the arc-shaped elastic support plate 233 will evenly distribute the support force to the surface of the tail rope, reducing the vertical jumping amplitude of the tail rope. At the same time, the limiting flange 24 will restrict the lateral movement of the tail rope and prevent it from jumping out from the side of the U-shaped groove 22.

[0044] When the tension of the tail rope changes, the positioning plate 254 moves under the action of the limit spring 253, automatically adjusting the tension of the tail rope to ensure the force balance of the tail rope. During the rotation of the tail rope, the main rotating shaft 33 rotates, driving the fixed ring 41 to rotate. The roller positioner 43 accurately positions the fixed tail rope rotator 44, ensuring that the tail rope maintains a stable rotation state during the rotation process. All components work together to effectively realize the anti-jumping function of the winch tail rope guide groove, improving the safety, stability and reliability of the winch equipment operation.
