Description

Technical Field

[0001] This utility model relates to the field of mining transportation technology, specifically to a mine bucket anti-rope detachment device. Background Technology

[0002] In mining, construction, and other fields, mine buckets are core equipment for vertical material transportation, and their operational safety directly affects work efficiency and personnel safety. Mine buckets are typically raised and lowered using hoisting ropes in conjunction with winches. However, during long-term use, the ropes are susceptible to axial or radial misalignment along load-bearing components due to factors such as bucket load fluctuations, track vibrations, and rope fatigue deformation. In severe cases, this can lead to the rope detaching from rotating rollers or other load-bearing structures, causing the bucket to fall, equipment damage, and other safety accidents. Traditional mine bucket rope protection often uses simple mechanical baffles or fixed limiting blocks. On the one hand, mechanical baffles can only achieve static limiting in one direction and cannot dynamically adjust the protective position according to rope deviation. When the rope deviates in an unexpected direction, the protective effect is greatly reduced. On the other hand, a certain gap needs to be reserved between the fixed limiting block and the rope to avoid frictional wear. Especially under the impact force at the moment of starting and stopping the mine bucket, the rope is prone to exceed the gap limit and deviate. At the same time, the protective device lacks a real-time monitoring mechanism and cannot detect the rope deviation trend in time, which may pose a certain degree of safety hazard. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a mine bucket anti-rope detachment device, which solves the problems described in the background section above.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a mine bucket anti-rope detachment device, including a mine bucket box and connecting frames provided at the four corners of the top of the mine bucket box, and also including a rotating roller, the rotating roller being rotatably installed in the inner cavity of the connecting frame, a displacement sensor being embedded in the inner bottom of the connecting frame, and fixing plates being alternately installed in the inner cavity of the connecting frame, with mounting grooves opened inside the fixing plates; A rotating assembly is installed in the inner cavity of the mounting groove, and an anti-disengagement buckle is installed inside the rotating assembly.

[0005] As a preferred embodiment of the present invention, the rotating assembly includes an annular electromagnetic slide rail installed inside the mounting groove, a sliding block installed on the annular electromagnetic slide rail, and a threaded cap fixedly installed on the inner side of the sliding block.

[0006] As a preferred technical solution of this utility model, the threaded cap set is equipped with an anti-disengagement buckle, which has a "U" shaped structure and threaded structures at both ends of the "U" anti-disengagement buckle. The two sets of anti-disengagement buckles are installed alternately above the rotating roller.

[0007] As a preferred embodiment of this utility model, the outer side of the connecting frame is symmetrically provided with adjustment components.

[0008] As a preferred technical solution of this utility model, the adjustment component includes linear electromagnetic slide rails symmetrically opened on the outside of the connecting frame, a slider is installed in the linear electromagnetic slide rail, a connecting plate is slidably installed on the slider, and a limit roller is rotatably installed between the connecting plates on both sides of the connecting frame.

[0009] As a preferred embodiment of this utility model, the rotating shaft of the limiting roller is provided with a limiting component on the inner side of the connecting plate.

[0010] As a preferred technical solution of this utility model, the limiting component includes a ratchet mounted on the limiting roller shaft, a pawl rotatably mounted on one side of the ratchet on the connecting plate, a spring mounted on the outer side of the pawl, an electromagnet fixedly mounted on one end of the spring, and the electromagnet fixedly mounted on the connecting plate.

[0011] This utility model has the following beneficial effects: 1. The fixed plate is equipped with a rotating assembly. During the lifting or lowering of the ore bucket by the rope, a displacement sensor collects the displacement data of the rotating roller in real time. When the rope deviates due to fluctuations in the ore bucket load or track vibration, if the displacement exceeds a preset value, the displacement sensor sends a warning signal to the control system. The rotating assembly then performs a four-fold protection action, including fine-tuning of the double-sided anti-disengagement buckles and limiting the movement of the two side limit rollers, to prevent the rope deviation from expanding. When the rope deviation exceeds the preset value, and the rope drives the two side limit rollers to rotate significantly, the ratchet on the limit roller shaft rotates synchronously at high speed, causing the pawl to quickly engage with the ratchet tooth groove, achieving one-way locking of the two side limit rollers. At the same time, the two sets of lateral anti-disengagement buckles maintain a double-sided lateral full-coverage state, forming an eight-fold three-dimensional protection with the double-sided anti-disengagement buckle wrapping and the locking of the two side limit rollers. This forcibly limits the rope's deviation in the horizontal direction and abnormal disengagement in the vertical direction, reducing the risk of rope derailment and improving the safety of the device.

[0012] 2. Adjustment components are symmetrically arranged on the outside of the connecting frame. When the outer circumferential surfaces of the limit rollers on both sides are in close contact with the outer surface of the rope, the linear electromagnetic slide rail is de-energized and the slider position is fixed by the electromagnetic locking function. At this time, the limit rollers on both sides form a lateral bidirectional limit on the rope, which not only prevents the rope from shifting to both sides of the connecting frame, but also does not affect the normal lifting of the rope along the axis of the rotating roller. At the same time, the limit rollers can rotate synchronously with the rope to avoid rope wear. Attached Figure Description

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.

[0017] The following is based on Figure 1 - Figure 7 This invention describes the anti-rope slippage device for mining buckets provided in an embodiment of the present invention.

[0018] Please see Figure 1 - Figure 7This utility model provides a technical solution: a mine bucket anti-rope detachment device, including a mine bucket box 1 and connecting frames 2 located at the four corners of the top of the mine bucket box 1. It also includes a rotating roller 3, which is rotatably installed in the inner cavity of the connecting frame 2. A displacement sensor 10 is embedded in the bottom of the inner cavity of the connecting frame 2. Fixing plates 6 are alternately installed in the inner cavity of the connecting frame 2, and the fixing plates 6 have mounting grooves 7 inside. Rotating assembly 8 is installed in the inner cavity of mounting groove 7. Anti-disengagement buckle 9 is installed inside the rotating assembly 8. The rotating assembly 8 includes an annular electromagnetic slide rail 801 installed inside the mounting groove 7. A sliding block 802 is installed on the annular electromagnetic slide rail 801. A threaded cap 803 is fixedly installed on the inner side of the sliding block 802. The threaded cap 803 is fitted with an anti-disengagement buckle 9. The anti-disengagement buckle 9 has a "U" shaped structure, and the two ends of the "U" anti-disengagement buckle 9 are provided with threaded structures. Two sets of anti-disengagement buckles 9 are staggered and installed above the rotating roller 3. In this embodiment, the operator inserts the rope through the lateral opening of one anti-disengagement buckle 9, around the outer circumference of the rotating roller 3, and then out through the lateral opening of the other anti-disengagement buckle 9. Finally, the operator adjusts the rope position so that it is precisely in the middle of the two limiting rollers 404, ensuring that the rope's central axis is parallel to the central axis of the rotating roller 3. At this point, the rotating roller 3 can rotate freely with the subsequent lifting action of the rope, reducing rope friction loss. After the rope is threaded, the control system synchronously sends an energizing signal to the two linear electromagnetic slide rails 401. The slider 402 slides horizontally inward along the linear electromagnetic slide rail 401, driving the connecting plate 403 and the limiting rollers 404 to move synchronously towards the rope. The rotation limits the rope, and simultaneously energizes the annular electromagnetic slide rail 801. The sliding block 802 slowly moves along the annular trajectory of the annular electromagnetic slide rail 801, driving the two sets of horizontally placed anti-disengagement buckles 9 to rotate synchronously around the center of the annular electromagnetic slide rail 801 through the threaded cap 803. When the horizontal openings of the two sets of anti-disengagement buckles 9 change from facing the inside of the connecting frame 2 to facing the left and right sides of the rope respectively, and the inner surface of the anti-disengagement buckle 9 contacts the outer surface of the rope, the annular electromagnetic slide rail 801 is de-energized and locked. The two sets of anti-disengagement buckles 9 form a protective structure around the rope. During the process of the rope driving the ore bucket box 1 to rise or fall, the displacement sensor 10 collects the displacement data of the rotating roller 3 in real time. When the rope fluctuates due to the load of the ore bucket... When track vibration causes deviation, if the displacement exceeds a preset value, the displacement sensor 10 sends a warning signal to the control system. Two sets of annular electromagnetic slide rails 801 are partially energized, driving the sliding block 802 to simultaneously adjust the two sets of lateral anti-disengagement buckles 9 towards the rope direction, reducing the lateral distance between the anti-disengagement buckles 9 and the rope. Simultaneously, the linear electromagnetic slide rails 401 on both sides are energized, fine-tuning the position of the slider 402 to ensure that the limit rollers 404 on both sides are always in close contact with the rope. Through the four-fold protection action of fine-tuning the double-sided anti-disengagement buckles 9 and limiting the position of the limit rollers 404 on both sides, the rope deviation is prevented from expanding. When the rope deviation exceeds the preset value, the tilt angle of the rotating roller 3 increases, and the displacement sensor 10 triggers a first-level alarm. The control system immediately sends a full-speed operation signal to the two sets of annular electromagnetic slide rails 801. The sliding block 802 drives the threaded caps 803 on the two sets of transverse anti-disengagement buckles 9 to rotate rapidly. The threaded structure at both ends of the anti-disengagement buckle 9 is further tightened with the threaded caps 803. The self-locking of the threads enhances the transverse locking force. The inner surface of the anti-disengagement buckle 9 is tightly attached to the rope, forming a double-sided transverse rigid restriction. Together with the two side limit rollers 404, it prevents the rope from coming off to the sides of the connecting frame 2. The rope will drive the two side limit rollers 404 to rotate significantly. The ratchet 501 on the shaft of the limit roller 404 rotates synchronously at high speed, causing the pawl 502 to quickly engage with the tooth groove of the ratchet 501, realizing the one-way locking of the two side limit rollers 404. At the same time, the two sets of transverse anti-disengagement buckles 9 maintain a double-sided transverse full-wrap state, forming an eight-fold three-dimensional protection with the double-sided anti-disengagement buckle 9 wrapping and the two side limit rollers 404 locking. This forcibly restricts the rope's deviation in the horizontal direction and abnormal disengagement in the vertical direction, reducing the risk of rope slippage.

[0019] Specifically, an adjustment component 4 is symmetrically arranged on the outer side of the connecting frame 2. The adjustment component 4 includes a linear electromagnetic slide rail 401 symmetrically opened on the outer side of the connecting frame 2. A slider 402 is installed in the linear electromagnetic slide rail 401. A connecting plate 403 is slidably installed on the slider 402. A limiting roller 404 is rotatably installed between the connecting plates 403 on both sides of the connecting frame 2. A limiting component 5 is provided on the inner side of the connecting plate 403 for the rotating shaft of the limiting roller 404. The limiting component 5 includes a ratchet 501 installed on the rotating shaft of the limiting roller 404. A pawl 502 is rotatably installed on one side of the ratchet 501 on the connecting plate 403. A spring 503 is installed on the outer side of the pawl 502. An electromagnet 504 is fixedly installed on one end of the spring 503. The electromagnet 504 is fixedly installed on the connecting plate 403. In this embodiment, after the rope is threaded, the control system synchronously sends an energizing signal to the linear electromagnetic slide rails 401 on both sides. The slider 402 slides horizontally inward along the linear electromagnetic slide rails 401, driving the connecting plate 403 and the limiting rollers 404 to move synchronously in the direction of the rope. When the outer circumferential surface of the limiting rollers 404 on both sides is in close contact with the outer surface of the rope, the linear electromagnetic slide rails 401 are de-energized and the position of the slider 402 is fixed by the electromagnetic locking function. At this time, the limiting rollers 404 on both sides form a lateral bidirectional limit on the rope, which not only prevents the rope from shifting to both sides of the connecting frame 2, but also does not affect the normal lifting of the rope along the axis of the rotating roller 3. At the same time, the limiting rollers 404 can rotate synchronously with the rope to avoid rope wear.

[0020] The working principle and usage process of this utility model: The operator inserts the rope through the opening of the horizontal anti-disengagement buckle 9 on one side, passes it around the rotating roller 3 in the connecting frame 2, and then exits it through the anti-disengagement buckle 9 on the other side, adjusting it to the middle of the two limit rollers 404. Subsequently, the control system drives the linear electromagnetic slide rails 401 on both sides, causing the slider 402 to move the connecting plate 403 and the limiting roller 404 toward the rope until they are in contact with the rope, forming a lateral bidirectional limiting. The limiting roller 404 can rotate with the rope to avoid wear. Simultaneously, the annular electromagnetic slide rail 801 is energized, and the sliding block 802 drives the two sets of anti-derailment buckles 9 to rotate around the slide rail, so that the openings of the anti-derailment buckles 9 turn to the left and right sides of the rope and contact the rope. After power is cut off and locking, a surrounding protection is formed. When the mine bucket is running, the displacement sensor 10 monitors the displacement of the rotating roller 3. If the rope deviates beyond the preset value, the anti-derailment buckles 9 are finely adjusted and the limiting roller 404 is in contact for quadruple protection. When the deviation increases further, a first-level alarm is triggered. The anti-derailment buckles 9 are locked by thread self-locking, and the ratchet 501 on the rotating shaft of the limiting roller 404 meshes with the pawl 502 to achieve unidirectional locking, ultimately forming an eight-fold three-dimensional protection to eliminate the risk of rope derailment.
