Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, specifically relating to a wire rope unwinding and rope protection device. Background Technology

[0002] During the mining process, winches are used to pull steel wire ropes to pull mine cars or heavy objects. Multiple rope release guards are installed at intervals along the traction path of the steel wire rope to prevent the steel wire rope from touching the ground and rubbing.

[0003] Existing derailleur devices, which provide support in a fixed position, cannot offer effective protection within the installation gap of the derailleur roller. They rely solely on the tautness of the wire rope to prevent contact with the ground. However, when the mine car is towed to the horizontal shaft opening, it continues to move a distance due to inertia, causing the wire rope to suddenly sag. The slack wire rope is prone to drooping and contacting the ground. During this dragging process, it not only causes surface wear and shortens the service life of the wire rope but also traps particles such as mud, sand, and gravel. When the wire rope is tensioned again, these particles are squeezed between the wire rope and the derailleur roller, and even between the strands of the wire rope, exacerbating wear and even leading to serious safety hazards such as broken wires or strands. Existing derailleur devices are ineffective in protecting slack wire ropes. Utility Model Content

[0004] This utility model provides a wire rope unrolling and rope protection device, which can prevent the wire rope from contacting the ground and wearing off throughout the process.

[0005] This utility model provides the following technical solution: a wire rope unwinding and rope protection device, comprising:

[0006] The self-adjusting support frame is able to rotate and rise as the pressure changes through an adjustment mechanism;

[0007] A rope guard roller is rotatably connected to the inner wall of the self-adjusting support frame to support the wire rope throughout the entire process. Two corner rollers are arranged diagonally on both sides of the rope guard roller, and the two corner rollers are rotatably connected to the inner walls of both sides of the self-adjusting support frame to lift the slack wire rope over a long distance.

[0008] The corner roller shaft is fixedly connected to a guide cone roller at one end away from the side wall of the self-adjusting support frame, for guiding the wire rope.

[0009] The self-adjusting support frame is provided with side limiting rollers at all four corners. The top height of the side limiting rollers is higher than the top height of the rope guard roller shaft, and the edge of the side limiting rollers protrudes from the side wall of the self-adjusting support frame.

[0010] Among them, the bottom ends of the two side limiting rollers on the same side are rotatably connected to a support frame, and the support frame is fixedly connected to the outer wall of the self-adjusting support frame.

[0011] The adjusting mechanism includes a built-in threaded cylinder, an external threaded sleeve, and an adjusting spring. The built-in threaded cylinder is threadedly connected to the external threaded sleeve, and the adjusting spring is accommodated within the built-in threaded cylinder and the external threaded sleeve.

[0012] The top of the built-in threaded cylinder is fixedly connected to a support plate, and the support plate is fixedly connected to the bottom of the self-adjusting support frame.

[0013] The outer wall of the external threaded sleeve is fixedly connected to a C-shaped bottom frame, and a gap is left between the support frame and the side wall of the C-shaped bottom frame.

[0014] The beneficial effects of this utility model are as follows: Based on the rolling support of the taut steel wire rope by the rope protection roller, it can further lift the steel wire rope over a long distance when it is slack by cooperating with the self-adjusting support frame that rotates and lifts with the pressure change and the corner roller. This prevents the steel wire rope from falling and dragging along the ground, thus avoiding wear and tear on the steel wire rope when it touches the ground. It also prevents particles adhering to the steel wire rope after it touches the ground from being squeezed and damaged during subsequent use, thereby improving the protective effect on the steel wire rope.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0021] Please see Figures 1-4 This utility model provides the following technical solution: a wire rope unwinding and rope protection device, comprising:

[0022] The self-adjusting support frame 1 can rotate and rise according to the pressure changes through the adjustment mechanism 4.

[0023] The rope guarding roller 2 is rotatably connected to the inner wall of the self-adjusting support frame 1 to support the wire rope throughout the entire process. Two corner rollers 21 are provided diagonally on both sides of the rope guarding roller 2. The two corner rollers 21 are rotatably connected to the inner walls of both sides of the self-adjusting support frame 1 to lift the slack wire rope over a long distance.

[0024] In this implementation plan: the C-shaped bottom frame 5 is installed on the movement path of the wire rope by welding or bayonet anchoring, and the wire rope is set along the top of the protective rope roller 2.

[0025] When the wire rope is used in a taut and taut state, the wire rope is in contact with the top of the protective roller 2. When the wire rope is pulled, the protective roller 2 supports the wire rope instead of the ground, and the relative rotation between the protective roller 2 and the wire rope reduces the wear of the wire rope. At this time, the wire rope will exert a downward force on the protective roller 2. The force is applied to the adjustment mechanism 4 through the self-adjusting support frame 1. The inner threaded cylinder 41 rotates and retracts in the outer threaded sleeve 42, and the adjusting spring 43 is in a compressed state in the inner threaded cylinder 41 and the outer threaded sleeve 42.

[0026] When the wire rope is in a slack state, the downward force exerted by the wire rope on the protective roller 2 is significantly reduced. The built-in threaded cylinder 41 rotates and rises under the elastic force of the adjusting spring 43, thereby driving the self-adjusting support frame 1 to rotate and rise synchronously. After the self-adjusting support frame 1 drives the protective roller 2 and the corner roller 21 to rise a certain distance, the protective roller 2 and the corner roller 21 rotate a certain angle relative to the U-shaped base frame 5. The two corner rollers 21 partially overlap on the path of the wire rope. Through the multi-point support of the wire rope by the protective roller 2 and the two corner rollers 21, compared to the single-point support of the protective roller 2, the multi-point support of the wire rope by the protective roller 2 and the two corner rollers 21 provides significant advantages. The support can lift the wire rope a longer distance, and the guard roller 2 and the corner roller 21 are at a higher height, which can effectively lift the wire rope a longer distance to a suspended state to counteract the fall of the wire rope in a slack state, thereby avoiding wear and tear after the wire rope touches the ground. It can also prevent oil and dirt particles adhering to the surface of the wire rope, thus preventing particles from contacting the guard roller 2 when the wire rope is pulled taut in subsequent processes. This also prevents particles from further compressing and damaging the wire rope under the pressure of the guard roller 2. When the distance between the wire rope traction trolley and the traction equipment is long, resulting in a long distance of slack and drooping of the wire rope, multiple devices can be used in combination.

[0027] A guide cone roller 22 is fixedly connected to one end of the corner roller 21 away from the side wall of the self-adjusting support frame 1 to guide the wire rope. The top height of the cone end of the guide cone roller 22 is lower than the top height of the rope guard roller 2, and thus lower than the bottom height of the wire rope. It can be inserted into the gap between the wire rope and the ground when the corner roller 21 rotates, and the wire rope is smoothly moved to the top position of the corner roller 21 under the guidance of the cone surface of the guide cone roller 22.

[0028] The self-adjusting support frame 1 is equipped with side limiting rollers 3 at all four corners. The top height of the side limiting rollers 3 is higher than the top height of the rope guarding roller shaft 2, and the edge of the side limiting rollers 3 protrudes from the side wall of the self-adjusting support frame 1. By setting the side limiting rollers 3, the wire rope can be limited to prevent it from falling off the ends of the rope guarding roller shaft 2 and the corner roller shaft 21. The side limiting rollers 3 can rotate freely, reducing friction with the wire rope.

[0029] The bottom ends of the two side limiting rollers 3 on the same side are rotatably connected to the support frame 31, and the support frame 31 is fixedly connected to the outer wall of the self-adjusting support frame 1. The side limiting rollers 3 can be supported by the support frame 31. In actual production, the support frame 31 and the self-adjusting support frame 1 can be fixed by welding.

[0030] The adjusting mechanism 4 includes an internal threaded cylinder 41, an external threaded sleeve 42, and an adjusting spring 43. The internal threaded cylinder 41 is threadedly connected to the external threaded sleeve 42, and the adjusting spring 43 is accommodated within the internal threaded cylinder 41 and the external threaded sleeve 42. The external wall of the internal threaded cylinder 41 is provided with threads, and the internal wall of the external threaded sleeve 42 is provided with threaded grooves. The adjusting spring 43 is installed within the internal threaded cylinder 41 and the external threaded sleeve 42. When the internal threaded cylinder 41 is not under pressure, it will rotate and rise upward under the elastic force of the adjusting spring 43. When the internal threaded cylinder 41 is under pressure, it will rotate and retract downward into the external threaded sleeve 42.

[0031] A support plate 44 is fixedly connected to the top of the built-in threaded cylinder 41, and the support plate 44 is fixedly connected to the bottom of the self-adjusting support frame 1. By setting the support plate 44, it can be connected to the self-adjusting support frame 1 with a larger area, increasing the connection strength. When the built-in threaded cylinder 41 rotates and rises, it drives the support plate 44 to move synchronously, thereby driving the self-adjusting support frame 1 to rotate and rise, and in turn driving the rope protection roller 2 and the corner roller 21 to rotate and rise.

[0032] An inverted U-shaped bottom frame 5 is fixedly connected to the outer wall of the external threaded sleeve 42. A gap is left between the support frame 31 and the side wall of the inverted U-shaped bottom frame 5. The inverted U-shaped bottom frame 5 serves as the bottom support structure. The upward protruding side of the inverted U-shaped bottom frame 5 can play a protective role to avoid side collisions. When the device is not in use, the side limiting roller 3 and the inverted U-shaped bottom frame 5 can be tied with ropes to position the self-adjusting support frame 1 and the rope guarding roller shaft 2, thereby limiting the rotation of the self-adjusting support frame 1 and the rope guarding roller shaft 2 and reducing the space occupied.

[0033] The working principle and usage process of this utility model are as follows: When the wire rope is used in a taut and traction state, the wire rope is in contact with the top of the protective roller 2. When the wire rope is pulled, the protective roller 2 supports the wire rope instead of the ground, and the relative rotation between the protective roller 2 and the wire rope reduces the wear of the wire rope. At this time, the wire rope will exert a downward force on the protective roller 2. The force is applied to the adjustment mechanism 4 through the self-adjusting support frame 1. The inner threaded cylinder 41 rotates and retracts into the outer threaded sleeve 42. The adjusting spring 43 is in a compressed state in the inner threaded cylinder 41 and the outer threaded sleeve 42. When the wire rope is used in a slack state, the downward force exerted by the wire rope on the protective roller 2 is significantly reduced, and the inner threaded cylinder 41 is compressed in the adjustment spring 43. Under the action of elasticity, the wire rope rotates and rises, which in turn drives the self-adjusting support frame 1 to rotate and rise synchronously. After the self-adjusting support frame 1 drives the rope guarding roller 2 and the corner roller 21 to rise a certain distance, the rope guarding roller 2 and the corner roller 21 rotate a certain angle relative to the U-shaped bottom frame 5. The two corner rollers 21 partially overlap on the path of the wire rope. Through the multi-point support of the wire rope by the rope guarding roller 2 and the two corner rollers 21, compared with the single-point support of the rope guarding roller 2, the multi-point support of the wire rope by the rope guarding roller 2 and the two corner rollers 21 can lift the wire rope a longer distance. Moreover, the rope guarding roller 2 and the corner roller 21 are at a higher height, which can effectively lift the wire rope a longer distance to a suspended state to counteract the fall of the wire rope in a slack state.
