[0006] Furthermore, the axial surface of the traction shaft is provided with grooves in a circumferential array, ridges are formed between adjacent grooves, and the grooves and the ridges are distributed in an alternating array in the circumferential direction of the traction shaft to form the concave-convex structure portion;
[0007] The groove or the ridge has a length extending in the axial direction of the traction shaft, a width extending in the circumferential direction, and a height extending in the radial direction.
[0008] Furthermore, the axial limiting wheel rotates synchronously with the traction shaft; the axial limiting wheel includes a fixed wheel half and a movable wheel half respectively located on both sides of the concave-convex structure portion, and the middle limiting gap is formed between the fixed wheel half and the movable wheel half in the axial direction; the fixed wheel half is fixedly arranged relative to the traction shaft; the movable wheel half is limited in the circumferential direction relative to the traction shaft by a circumferential limiting structure, and the movable wheel half is slidably arranged relative to the traction shaft in the axial direction; when the movable wheel half slides along the traction shaft, the width of the middle limiting gap between it and the fixed wheel half is changed.
[0009] Furthermore, the movable wheel half has an axial push-pull driving mechanism with an axis parallel to the axis; a circle of guide grooves with a slider is opened on the outer periphery of the movable wheel half, and the push-pull driving end of the axial push-pull driving mechanism is connected to the slider to provide the movable wheel half with a driving force for axial displacement along the traction shaft.
[0010] Furthermore, the shaft end surfaces of the fixed wheel half and the movable wheel half that form the middle limiting gap are both friction surface structures with textures.
[0011] Furthermore, the circumferential limiting structure is composed of an axial guide groove on the axial surface of the traction shaft and an axial protrusion on the inner ring of the movable wheel half that are axially slidably embedded.
[0012] Furthermore, the radial limiting wheel is provided with a radial push-pull driving mechanism; the outer periphery of the radial limiting wheel has a rope pressing ring body, and the radial push-pull driving mechanism pushes and pulls the radial limiting wheel to make the rope pressing ring body radially move in and out of the middle limiting gap; the width of the rope pressing ring body is smaller than the radial dimension of the steel rope.

[0015] Beneficial effect: The present invention uses a steel rope guiding control device to guide and control the steel rope when it is hoisting mining equipment into the mine. During the guiding control process, the axial limiting wheel limits the axial position of the steel rope within the middle limiting gap, and cooperates with the rope pressing action of the radial limiting wheel extending into the middle limiting gap to make the radial limiting steel rope fit the concave and convex structure on the traction shaft. Therefore, during the forward rotation of the traction shaft in the loose rope state, the traction steel rope is guided and conveyed, and the amplitude of the lifting swing is reduced. When encountering an obstacle or the equipment is deflected, the rope can be locked and pulled back to avoid obstacles or stabilized. When the equipment is deflected, a temporary rope locking operation is performed to reduce the swing amplitude of the steel rope and then switch to the loose rope state to continue the lifting work. When encountering an obstacle, the rope locking operation is performed, and the traction shaft is reversed to drive the steel rope to pull back the mining equipment. In the process of pulling back the mining equipment, the obstacle is avoided by relying on the shaking state of the driven equipment. At the moment of misalignment, the equipment is switched to the loose rope state to continue lowering the equipment, thereby avoiding the obstacle to improve the lifting safety and efficiency.

[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] like Figure 1 As shown, a hoisting system with steel rope guidance and stability control includes a winch 1 and a steel rope guidance control device 2 arranged at the wellhead of a mine 5. The steel rope 4 led out from the winch 1 is controlled by the steel rope guidance control device 2 to lift the mining equipment 3 into the mine 5.
[0023] In the prior art, when a winch is used to lift mining equipment, the steel rope wound on the drum is displaced in the axial direction during the rope release process. As a result, the lifting of the mining equipment will cause an increase in the amplitude of shaking. Especially when encountering obstacles on the shaft wall, it is difficult for the mining equipment to avoid the obstacles, and frequent lifting and lowering are required to avoid the obstacles. The probability of collision between the equipment and the obstacles is relatively high, affecting the safety and efficiency of the lifting.
[0024] In order to solve the above problems, the present invention further provides a technical solution as follows: Figure 2 As shown, the steel rope guiding control device 2 includes a traction shaft 6 and an axial limiting wheel 7 arranged on the traction shaft 6; a concave-convex structure portion 60 is arranged circumferentially on the traction shaft 6, and the axial limiting wheel 7 has a middle limiting gap 70, and the concave-convex structure portion 60 is located in the middle limiting gap 70, and the steel rope 4 passes through the middle limiting gap 70 and is arranged around the concave-convex structure portion 60; a radial limiting wheel 8 is arranged corresponding to the middle limiting gap 70, and the radial limiting wheel 8 is relatively spaced relative to the middle limiting gap The gap 70 is radially arranged in and out, and the radial limiting wheel 8 rolls the steel rope 4 when radially entering the middle limiting gap 70, so that the rope body part of the steel rope 4 around the traction shaft 6 remains in contact with the concave-convex structure part 60; the width of the middle limiting gap 70 is adjustable, constituting a loose rope state with a larger adjustment and a locked rope state with a smaller adjustment; in the loose rope state, the traction shaft 6 rotates to pull and guide the conveying steel rope 4 through the concave-convex structure part 60; in the locked rope state, the steel rope 4 is fixed relative to the traction shaft 6 by clamping the axial limiting wheel 7. The present invention guides and controls the steel rope 4 when hoisting the mining equipment 3 down the well through the steel rope guiding control device 2. During the guiding and controlling process, the axial limiting wheel 7 limits the axial position of the steel rope within the middle limiting gap 70, and cooperates with the rope pressing action of the radial limiting wheel 8 extending into the middle limiting gap 70 to make the radial limiting steel rope 4 fit the concave-convex structure 60 on the traction shaft 6, so that during the forward rotation of the traction shaft 6 in the loose rope state, the traction steel rope 4 realizes guided transportation, reduces the amplitude of hoisting shaking, and can lock the rope and pull back to avoid obstacles or stabilize when encountering obstacles or equipment deflection. When the equipment is deflected, a temporary rope locking operation is performed to reduce the swing amplitude of the steel rope 4 and then switch to the loose rope state to continue the hoisting work. When an obstacle is encountered, the rope locking operation is performed, and the traction shaft 6 is reversed to drive the steel rope 4 to pull back the mining equipment. In the process of pulling back the mining equipment, the obstacle is avoided by relying on the shaking state of the driven equipment. At the moment of misalignment, the equipment is switched to the loose rope state to continue lowering the equipment, thereby avoiding the obstacle to improve the hoisting safety and efficiency.
[0025] The concave-convex structure portion 60 of the present invention has the function of traction steel rope 4 when it rotates through the traction shaft 6 under the rope pressing action of the radial limiting wheel 8, and has the structure as follows: the axial surface of the traction shaft 6 is provided with grooves in a circumferential array, and ridges are formed between adjacent grooves, and the grooves and the ridges are distributed in an alternating array around the circumference of the traction shaft 6 to form the concave-convex structure portion 60; at the same time, in order to improve the traction effect of the concave-convex structure portion 60, the grooves or the ridges have a length extending in the axial direction of the traction shaft 6, a width extending in the circumferential direction, and a height extending in the radial direction.
[0026] like Figure 3 , Figure 4 as well as Figure 5As shown, the axial limiting wheel 7 rotates synchronously with the traction shaft 6; the axial limiting wheel 7 includes a fixed wheel half 7.1 and a movable wheel half 7.2 respectively located on both sides of the concave-convex structure portion 60, and the fixed wheel half 7.1 and the movable wheel half 7.2 form the middle limiting gap 70 in the axial direction; the fixed wheel half 7.1 is fixedly arranged relative to the traction shaft 6, and is connected and fixed to the traction shaft 6 by a pin 17; in order to prevent the movable wheel half 7.2 from circumferentially moving without affecting its axial movement, the movable wheel half 7.2 is limited in the circumferential direction relative to the traction shaft 6 by a circumferential limiting structure, and the movable wheel half 7.2 is slidingly arranged relative to the traction shaft 6 in the axial direction; as shown Figure 4 As shown, the circumferential limiting structure is composed of an axial guide groove 61 on the axial surface of the traction shaft 6 and an axial protrusion 7.21 on the inner ring of the movable wheel half 7.2, which is axially slidably embedded; when the movable wheel half 7.2 slides along the traction shaft 6, the width of the middle limiting gap 70 between it and the fixed wheel half 7.1 is changed. When the width of the middle limiting gap 70 is reduced, it can be switched to the rope locking state, that is, the movable wheel half 7.2 cooperates with the fixed wheel half 7.1 to clamp the steel rope 4. When the width of the middle limit gap 70 is increased, it can be switched to the loose rope state, that is, the movable wheel half 7.2 and the fixed wheel half 7.1 do not clamp the steel rope 4, and the movable wheel half 7.2 and the fixed wheel half 7.1 play a role of axially blocking the steel rope 4, that is, the axially limited steel rope 4 is located in the middle limit gap 70, and at the same time cooperates with the radial limitation of the radial limit wheel 8 extending into the middle limit gap 70, so that the steel rope 4 is always in the middle limit gap 70 to avoid rope slippage.
[0027] like Figure 3 As shown, the movable wheel half 7.2 has an axial push-pull drive mechanism 9 with parallel axes; the outer circumference of the movable wheel half 7.2 is provided with a circle of guide grooves 7.20 with sliders 16, and the push-pull drive end of the axial push-pull drive mechanism 9 is connected to the sliders 16 to provide the movable wheel half 7.2 with a driving force for axial displacement along the traction shaft 6, while ensuring that the movable wheel half 7.2 can slide along the traction shaft 6, the setting of the guide grooves 7.20 can not affect the normal rotation of the axial limiting wheel 7 following the traction shaft 6. The radial limiting wheel 8 is provided with a radial push-pull drive mechanism 10, and the axial push-pull drive mechanism 9 is preferably an axial cylinder parallel to the axis of the traction shaft 6, and the radial push-pull drive mechanism 10 is preferably a radial cylinder arranged radially relative to the traction shaft 6.
[0028] In order to ensure the firmness of the lock rope, in the present invention, Figure 4 As shown, the axial end surfaces of the fixed wheel half 7.1 and the movable wheel half 7.2 that form the middle limiting gap 70 are both friction surface structures 70a with textures.
[0029] The outer circumference of the radial limiting wheel 8 is provided with a rope pressing ring body 80, and the radial push-pull driving mechanism 10 pushes and pulls the radial limiting wheel 8 to make the rope pressing ring body 80 radially enter and exit the middle limiting gap 70, and the rope pressing is implemented by the rope pressing ring body 80. In order to ensure the effective implementation of the rope locking process when the middle limiting gap 70 is reduced, the obstruction of the width of the rope pressing ring body 80 is eliminated. Therefore, the width of the rope pressing ring body 80 is smaller than the radial dimension of the steel rope 4. During the rope locking process, in order to avoid the rope coming off, the rope pressing effect still exists, but the rope pressing force gradually decreases, that is, the rope pressing ring body 80 gradually withdraws from the middle limiting gap 70 under the pulling action of the radial push-pull driving mechanism 10, and when the rope locking action is completed, the rope pressing ring body 80 completely withdraws from the middle limiting gap 70.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the steel rope guide control device 2 also includes a base 12 for transversely setting the traction shaft 6 at the wellhead of the mine 5 through a vertical bearing seat 11; the vertical bearing seat 11 is a pair of two shaft ends of the traction shaft 6; one shaft end of the traction shaft 6 is connected to the vertical bearing seat 11, and is connected to a three-phase asynchronous motor 14 through a coupling 13; the other shaft end of the traction shaft 6 is connected to a shaft body 15 set on the corresponding vertical bearing seat 11, and the radial dimension of the shaft body 15 is smaller than the radial dimension of the traction shaft 6. The base 12 is set across the wellhead of the mine 5, so that the steel rope guide control device 2 is seated at the wellhead of the mine 5 through the base 12, and the steel rope 4 guided and controlled by the steel rope guide control device 2 shuttles through the gap 120 opened in the base 12 corresponding to the mine 5.
[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
