Description

Technical Field

[0001] The invention relates to the technical field of control devices for inclined mine hoists, and in particular to a main rope tension control device for inclined mine hoists. Background Art

[0002] Inclined mine hoist is a kind of mechanical equipment specially used for lifting ore, personnel, equipment and materials in inclined shafts.

[0003] The existing inclined mine hoist usually includes a hoisting container, a wire rope, a hoist drum, a driving device and an electronic control system. The driving device drives the hoist drum to realize the retraction and release of the hoisting container with the cooperation of the wire rope. During the operation, the tension of the wire rope is mainly controlled by the electronic control system sensing the rotation speed of the hoist drum. When the rotation speed is too fast, the wire rope is taut and the tension is large, which can easily cause the wire rope to break. Therefore, the electronic control system controls the driving device to slow down and reduce the rotation speed of the hoist drum, thereby reducing the tension of the wire rope. However, due to the complex working environment of the inclined mine hoist, it is difficult to ensure that the electronic control system has been running stably. Once the electronic control system fails, due to the lack of stable protection measures, at this time, if the driving device drives the wire rope to be quickly wound or released through the hoist drum, the materials and personnel in the hoisting container will move rapidly along the inclined mine, which can easily cause material loss and easily cause injuries to the personnel in the hoisting container, affecting the continuous operation of the inclined mine.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: when the winding roller rotates too fast, the deceleration mechanism slows down the speed of the winding roller through friction, so as to prevent the winding rope from being too loose or too tight, thereby preventing damage to the winding rope. At the same time, the deceleration mechanism drives the cooling mechanism to deliver coolant to the deceleration mechanism to cool the deceleration mechanism, so as to prevent the deceleration mechanism from being overheated and causing a reduction in the deceleration effect. The positioning mechanism limits the deceleration mechanism, so that the deceleration mechanism maintains a stable deceleration effect. Specifically: 1. When the winding roller rotates at high speed, the winding roller drives the connecting column to rotate through the mutually meshing reduction gear and the connecting gear. The reduction block, the adjusting sliding column and the reduction sleeve rotate synchronously. The positioning bracket drives the reduction plate to move along the reduction slide groove toward the friction ring under the action of centrifugal force. The friction between the reduction plate and the friction plate reacts on the connecting column, reducing the speed of the connecting gear and the reduction gear, reducing the speed of the winding roller, and then adjusting the tension of the winding rope to avoid damage to the winding rope. 2. The connecting column drives the matching bevel gear to rotate through the connecting groove wheel, the transmission belt, the power groove wheel and the power bevel gear in turn, and the matching bevel gear drives the matching column to rotate. During the rotation of the matching column, the matching column drives the counterweight ball to rotate through the matching connecting rod, and the matching connecting rod drives the matching plate to slide upward along the matching column through the matching support arm. The matching sleeve moves upward synchronously and drives the connecting frame to rotate, and the driving frame moves downward. The rotating bracket drives the rotating dial plate to rotate and dials the sliding dial block. The sliding dial block drives the rotating slider to slide along the fixed slide groove. The rotating slider drives the adjusting sleeve to move away from the friction ring through the adjusting bracket. The deceleration sleeve drives the positioning bracket and the deceleration plate to move towards the friction ring through the deceleration support arm, thereby avoiding the deceleration sleeve from freely moving under the action of the deceleration spring, causing the deceleration plate to be out of contact with the friction ring, ensuring the efficient deceleration effect of the winding roller and improving the protection ability of the winding rope. 3. During the rotation, the matching plate drives the support sleeve and the support seat to move upward synchronously. The support seat drives the sealing rod and the sealing head to move upward synchronously through the matching head. The coolant flows out of the cooling barrel through the gap through the lower liquid pipe and enters the cooling cavity through the cooling pipe to cool the friction ring and the friction plate, avoiding the decrease of the friction coefficient between the friction ring and the friction plate due to high temperature, thereby ensuring the efficient deceleration effect of the friction ring.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0029] Combined with Figure 1 , Attachment Figure 2 With attached Figure 3As shown, a main rope tension control device for an inclined mine hoist comprises a base 1, a winding roller 11, a winding rope 12, a winding motor 14 and a reducer 15.

Mechanism 2, the base 1 is provided with a cooling mechanism 4 driven by the reduction mechanism 2 to cool the friction ring 24, the base 1 is provided with a positioning mechanism 3 driven by the reduction mechanism 2 to prevent the reduction mechanism 2 from moving, the base 1 is provided with a tensioning mechanism 5 for adjusting the tension of the winding rope 12, the base 1 is provided with a cover plate 16, the base 1 is provided with a stop mechanism 6 for preventing the winding roller 11 from rotating freely, the stop mechanism 6 includes an electric push rod 61 arranged on the base 1, and the telescopic end of the electric push rod 61 is provided with a stop plate 62 cooperating with the winding roller 11.

[0030] The working principle of the present invention is as follows: the winding motor 14 is started and drives the winding roller 11 to rotate through the speed reducer 15, and the winding rope 12 can be driven to be retracted and released through the forward and reverse rotation of the winding roller 11. During the process of retracting and releasing the winding rope 12, when the rotation speed of the winding roller 11 is too fast, the winding roller 11 drives the speed reduction mechanism 2 to move, and the speed reduction mechanism 2 slows down the rotation speed of the winding roller 11 through friction, so as to avoid the winding rope 12 being too loose or too tight, thereby preventing damage to the winding rope 12. In the process of the speed reduction mechanism 2 decelerating the winding roller 11, the speed reduction mechanism 2 drives the cooling mechanism 4 to operate, and the cooling mechanism 4 transports the coolant to the speed reduction mechanism 2 to cool the speed reduction mechanism 2, so as to avoid the speed reduction mechanism 2 overheating and thus reducing the deceleration effect. Furthermore, the positioning mechanism 3 limits the speed reduction mechanism 2, so that the speed reduction mechanism 2 maintains a stable deceleration effect, and the tensioning mechanism 5 assists in controlling the tension of the winding rope 12 to improve the protection capability of the winding rope 12.

[0031] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 5 With attached Figure 6 As shown, the deceleration mechanism 2 includes a deceleration gear 21 arranged at the end of the winding roller 11, a connecting gear 211 meshing with the deceleration gear 21 is rotatably provided on the base 1, a connecting column 22 is provided on the connecting gear 211, a deceleration block 222 is provided on the connecting column 22, and the deceleration block 222 is arranged at least two groups equidistantly around the connecting column 22 in the circumferential direction, and a deceleration slide groove 2221 is provided on the deceleration block 222; The end of the connecting column 22 is provided with an adjusting slide column 223, on which a deceleration sleeve 225 is slidably provided, and a raised key is provided on the adjusting slide column 223; a deceleration spring 224 connected to the deceleration sleeve 225 is provided on the deceleration block 222; a deceleration arm 226 is rotatably provided on the deceleration sleeve 225; a positioning bracket 23 rotatably connected to the deceleration arm 226 is slidably provided in the deceleration slide groove 2221; a deceleration plate 234 is slidably provided on the positioning bracket 23; the deceleration plate 234 is an arc-shaped structure; a positioning slide groove 231 is provided on the positioning bracket 23; a positioning slider 232 connected to the deceleration plate 234 is slidably provided on the positioning slide groove 231; a positioning screw 233 that is threadedly matched with the positioning slider 232 is rotatably provided on the positioning bracket 23; a counterweight 235 is provided on the deceleration plate 234; a friction ring 24 that matches with the deceleration plate 234 is provided on the base 1; and a friction plate 241 that matches with the deceleration plate 234 is provided on the inner side of the friction ring 24.

[0032] Working principle of the speed reduction mechanism 2: When the winding roller 11 rotates at a high speed, the winding roller 11 drives the meshing connecting gear 211 to rotate through the speed reduction gear 21, and the connecting gear 211 drives the connecting column 22 connected thereto to rotate, and the speed reduction block 222, the adjusting slide column 223 and the speed reduction sleeve 225 rotate synchronously. During the rotation of the speed reduction block 222, under the action of centrifugal force, the positioning bracket 23 moves along the speed reduction slide groove 2221 toward the direction close to the friction ring 24, and the speed reduction plate 234 moves synchronously toward the direction close to the friction ring 24 to abut against the friction plate 241, and the friction force between the speed reduction plate 234 and the friction plate 241 reacts It is used to connect the column 22, reduce the rotation speed of the connecting gear 211 and the reduction gear 21, and reduce the rotation speed of the winding roller 11. In this process, the positioning bracket 23 drives the reduction sleeve 225 to move away from the friction ring 24 along the adjusting slide column 223 through the reduction arm 226, and the reduction sleeve 225 squeezes the reduction spring 224, and the reduction spring 224 contracts and accumulates force. When the speed of the winding roller 11 is appropriate, the reduction spring 224 is reset and drives the positioning bracket 23 to reset through the reduction arm 226, and the reduction plate 234 is out of contact with the friction plate 241, thereby reducing the friction force of the winding roller 11 and reducing the energy consumption of the winding motor 14; By rotating the positioning screw 233, due to the sliding limiting effect of the positioning slot 231 on the positioning slider 232, the positioning screw 233 drives the positioning slider 232 to slide along the positioning slot 231, and the positioning slider 232 drives the speed reduction plate 234 connected thereto to move synchronously, thereby changing the initial spacing between the speed reduction plate 234 and the friction plate 241. Under the condition of the same rotation speed of the reduction gear 21, the initial spacing between the speed reduction plate 234 and the friction plate 241 is small, and the friction force between the speed reduction plate 234 and the friction plate 241 is large. On the contrary, the initial spacing between the speed reduction plate 234 and the friction plate 241 is large, and the friction force between the speed reduction plate 234 and the friction plate 241 is small, thereby conveniently adjusting the deceleration effect of the speed reduction plate 234 on the winding roller 11.

[0033] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 With attached Fig.10 As shown, the deceleration sleeve 225 is provided with an adjustment sleeve 227, the positioning mechanism 3 includes a fixed slide groove 33 arranged on the base 1, a rotating slider 332 is slidably provided on the fixed slide groove 33, an adjustment bracket 3322 rotatably matched with the adjustment sleeve 227 is provided at one end of the rotating slider 332, a sliding block 3321 is provided at the other end of the rotating slider 332, a rotating bracket 331 is rotatably provided at one side of the fixed slide groove 33, a rotating plate 3312 matched with the sliding block 3321 is provided on the rotating bracket 331, and a driving mechanism for driving the rotating bracket 331 to rotate is provided on the base 1; The driving mechanism includes a matching bevel gear 31 rotatably arranged on the base 1 and rotating with the connecting gear 211, a connecting groove wheel 221 is arranged on the connecting column 22, a power column 36 is rotatably arranged on the base 1, a power bevel gear 361 meshing with the matching bevel gear 31 is arranged at one end of the power column 36, a power groove wheel 362 is arranged at the other end of the power column 36, and a transmission belt 363 is arranged between the power groove wheel 362 and the connecting groove wheel 221; The mating bevel gear 31 is provided with a mating column 311, and a mating plate 312 is slidably sleeved on the mating column 311. A mating arm 313 is rotatably provided on the mating plate 312, and two groups of mating arms 313 are symmetrically arranged. A mating connecting rod 314 rotatably connected to the mating supporting arm 313 is rotatably provided on the mating column 311, and a counterweight ball 315 is provided at the end of the mating connecting rod 314. A mating sleeve 316 is provided at the lower end of the mating plate 312. A supporting frame 32 is rotatably provided on the supporting frame 32, and a connecting frame 321 rotatably matched with the matching sleeve 316 is rotatably provided. A driving frame 322 is rotatably provided at one end of the connecting frame 321, and a driving slide groove 3221 is provided on the driving frame 322. A rotating rod 3311 slidably matched with the driving slide groove 3221 is provided on the rotating bracket 331.

[0034] Working principle of positioning mechanism 3: during the rotation of connecting column 22 with connecting gear 211, connecting column 22 drives power groove wheel 362 to rotate through connecting groove wheel 221 and transmission belt 363, power groove wheel 362 drives connected power bevel gear 361 to rotate, power bevel gear 361 drives matching column 311 to rotate through matching bevel gear 31 meshed therewith, during the rotation of matching column 311, matching column 311 drives counterweight ball 315 to rotate through matching connecting rod 314, centrifugal force generated by the rotation of counterweight ball 315 causes counterweight ball 315 to generate force to move horizontally toward the connection point between matching connecting rod 314 and matching column 311, thereby causing matching connecting rod 314 to rotate, matching connecting rod 314 drives matching plate 312 to slide upward along matching column 311 through matching support arm 313, matching sleeve 316 moves upward synchronously, further, matching The sleeve 316 drives the connecting frame 321 to rotate. Since the slidingly matched rotating rod 3311 slides with the driving slide groove 3221, the connecting frame 321 drives the driving frame 322 to move downward during the rotation process. The driving frame 322 drives the rotating bracket 331 to rotate. The rotating bracket 331 drives the rotating dial plate 3312 to rotate and dial the sliding dial block 3321. The sliding dial block 3321 drives the rotating slider 332 to slide along the fixed slide groove 33. The rotating slider 332 drives the adjusting sleeve 227 to move toward the friction ring 24 through the adjusting bracket 3322. The deceleration sleeve 225 drives the positioning bracket 23 and the deceleration plate 234 to move toward the friction ring 24 through the deceleration support arm 226, thereby avoiding the deceleration sleeve 225 from freely moving under the action of the deceleration spring 224, causing the deceleration plate 234 to be out of contact with the friction ring 24.

[0035] Combined with Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 With attached Fig.10 As shown, a locking block 34 is provided on one side of the fixed slide groove 33, and a locking rod 341 extending from the locking block 34 is slidably provided in the locking block 34, and a locking baffle 343 slidingly matched with the locking block 34 is provided at one end of the locking rod 341 extending into the locking block 34, and the locking baffle 343 is a wedge-shaped structure, and a locking spring 342 connected to the locking baffle 343 is sleeved on the locking rod 341.

[0036] The working principle of the locking pull rod 341 is as follows: when the rotating slider 332 slides along the fixed slide groove 33 toward the friction ring 24, the rotating slider 332 first contacts with the locking baffle 343 of the wedge-shaped structure, and the inclined surface of the locking baffle 343 contacts with the rotating slider 332. The rotating slider 332 pushes the locking baffle 343 to slide along the locking block 34, and the locking spring 342 is forced to shrink. After that, the plane of the locking baffle 343 contacts with the rotating slider 332. As the rotating slider 332 continues to move, the rotating slider 332 disengages from the locking baffle 343, the locking spring 342 resets and drives the locking baffle 343 to reset, and the locking baffle 343 blocks the rotating slider 332, thereby preventing the rotating slider 332 from moving freely.

A mating head 433 is provided at the other end of the sealing rod 43. A support sleeve 35 is fixedly provided on the mating plate 312. A support seat 351 rotatably matched with the mating head 433 is provided on the support sleeve 35. A liquid replenishing pipe 421 and a lower liquid pipe 422 are connected on the cooling barrel 42. A cooling cavity 242 is provided on the friction ring 24. A cooling pipe 243 connected with the lower liquid pipe 422 is provided on the cooling cavity 242. A liquid outlet pipe 244 is provided at the lower end of the cooling cavity 242. A liquid outlet valve 245 is provided on the liquid outlet pipe 244.

[0038] The working principle of the cooling mechanism 4: the matching plate 312 drives the support sleeve 35 and the support seat 351 to move upward synchronously during the rotation process, the support seat 351 drives the matching head 433 that rotates with it to move upward synchronously, the matching head 433 drives the sealing head 431 to move upward synchronously through the sealing rod 43, the sealing spring 432 is forced to shrink, and during the upward movement of the sealing head 431, a gap appears between the sealing head 431 and the cooling barrel 42. At this time, the coolant can flow out of the cooling barrel 42 through the gap through the lower liquid pipe 422 and enter the cooling chamber 242 through the cooling pipe 243, thereby cooling the friction ring 24 and the friction plate 241, thereby ensuring the efficient deceleration effect of the friction ring 24.

[0040] The working principle of the tensioning mechanism 5 is as follows: the winding rope 12 passes through a group of the guide rollers 511, the tensioning roller 521 and the other group of the guide rollers 511 in sequence. When the winding rope 12 is too tight, the winding rope 12 squeezes the tensioning roller 521, and the tensioning roller 521 squeezes the tensioning spring 522 through the tensioning slider 52. The tensioning spring 522 contracts under the force, and at this time, the winding rope 12 relaxes. On the contrary, when the winding rope 12 is too loose, the tensioning spring 522 drives the tensioning roller 521 to squeeze the winding rope 12 through the tensioning slider 52, so that the winding rope 12 is tightened to prevent the winding rope 12 from loosening.

[0041] When the present invention is implemented, the winding motor 14 is started, and the winding motor 14 drives the winding roller 11 to rotate through the reducer 15. Under normal operation, the speed of the winding roller 11 is within the control range. At this time, the elastic action of the deceleration spring 224 drives the deceleration sleeve 225 to move away from the friction ring 24, and the deceleration arm 226 drives the positioning bracket 23 and the deceleration plate 234 to move away from the friction ring 24. At this time, the deceleration plate 234 does not contact the friction ring 24, thereby reducing the friction force of the winding roller 11. When the winding roller 11 rotates too fast, the winding roller 11 drives the reduction gear 21 to rotate, and the connecting gear 211 drives the connecting column 22 to rotate. Under the action of centrifugal force, the positioning bracket 23 drives the reduction plate 234 to move toward the friction ring 24 and abut against the friction plate 241, thereby reducing the rotation speed of the winding roller 11. At the same time, the connecting column 22 drives the power bevel gear 361 to rotate, the matching plate 312 drives the matching sleeve 316 to move upward, the connecting frame 321 rotates, the driving frame 322 moves downward, the driving frame 322 drives the rotating bracket 331 to rotate, and the rotating bracket 331 drives the rotating dial plate 3312 to rotate and toggle the sliding dial Block 3321, the rotating slider 332 drives the adjusting sleeve 227 to move away from the friction ring 24, the deceleration sleeve 225 drives the positioning bracket 23 and the deceleration plate 234 to move towards the friction ring 24 through the deceleration support arm 226. At the same time, the support sleeve 35 and the support seat 351 move upward synchronously, and the support seat 351 drives the sealing rod 43 to drive the sealing head 431 to move upward synchronously through the matching head 433. The coolant flows out of the cooling barrel 42 through the gap through the lower liquid pipe 422 and enters the cooling chamber 242 through the cooling pipe 243, so as to cool down the friction ring 24 and the friction plate 241, thereby ensuring the efficient deceleration effect of the friction ring 24.

[0042] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
