Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and more particularly to a mine shaft auxiliary lifting device. Background Art

[0002] Mine shaft hoist is a key equipment of mine shaft hoisting system. It is mainly composed of motor, reducer, drum, brake device, depth indicator and other components. Its working principle is that the motor provides power and drives the drum to rotate through the reducer. One end of the wire rope wound on the drum is connected to the lifting container (such as a bucket or a cage). When the drum rotates, the wire rope is retracted and released, so that the lifting container rises or falls in the shaft of the shaft, completing the lifting of ore and materials or the lifting and lowering of personnel.

[0003] At present, when the existing hoist is used in the working environment of the mine, since the mine is filled with a large amount of different types of dust such as coal dust and rock dust, when the hoist is running, the surface of the wire rope is coated with a sticky lubricant, which makes these dusts easily adhere to the surface of the wire rope and difficult to separate from the wire rope. In the process of the drum winding and unwinding the wire rope, the attached dust has different degrees of friction with the wire rope and the drum when the wire rope and the drum move relative to each other, just like fine abrasives, continuously acting on the surface of the drum and the wire rope, thereby causing wear to the surface of the drum and the wire rope. In addition, if too much dust accumulates on the surface of the wire rope for a long time, its heat dissipation will be hindered, causing the internal temperature of the wire rope to rise, which may reduce the strength and fatigue life of the metal material, increase the risk of wire rope failure, and shorten the service life of the wire rope.

[0004] At present, the existing hoist is used in the working environment of the mine. Since the mine is filled with a large amount of coal dust, rock dust and other different types of dust, when the hoist is running, the surface of the wire rope is usually coated with a lubricant with sticky properties, which makes the surrounding dust very easy to adhere to the surface of the wire rope and difficult to detach due to the sticky effect. During the winding and unwinding operation of the drum, the dust attached to the wire rope will form different degrees of friction interaction with the wire rope and the drum when it moves relative to the drum. In particular, the high hardness of coal dust makes this friction effect like a fine abrasive, which continuously erodes and wears the surface of the drum and the wire rope. In addition, if a large amount of dust accumulates on the surface of the wire rope for a long time, it will hinder its heat dissipation performance, causing the internal temperature of the wire rope to gradually increase. The increase in temperature may cause problems such as reduced strength of metal materials and shortened fatigue life. This undoubtedly significantly increases the risk of wire rope failure, and ultimately greatly reduces the service life of the wire rope, seriously affecting the overall stability and reliability of the hoist system.

[0039] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0040] Embodiment 1

[0041] Please refer to Figure 1 to Figure 2 , an auxiliary lifting device for a mine shaft, comprising: a mounting seat 1, a power mechanism 2, a reel 3, a lifting container 4 and a maintenance mechanism 5 for maintaining the steel wire rope wound on the reel 3. Among them, the mounting seat 1 is fixedly installed at the wellhead position of the shaft, the power mechanism 2 and the reel 3 are both installed on the top surface of the mounting seat 1, and the driving end of the power mechanism 2 is connected to the reel 3, and the reel 3 is driven to rotate by the power mechanism 2, so that the reel 3 can perform the reeling or unreeling operation on the steel wire rope wound thereon, and the lifting container 4 is connected to the end of the steel wire rope, so that the lifting container 4 can perform the lifting action, and the power mechanism 2 includes a motor, a reducer, a brake and other structures, because it belongs to the prior art in this field, its specific structure and principle will not be described in detail here.

[0042] Please refer to Figures 2 to 3 The maintenance mechanism 5 includes a support frame 51, a rotating drum 52, a surface cleaning component 53, a rotating drive component 54 and a lubricant coating component 55. The support frame 51 is fixedly connected to the mounting seat 1, and the rotating drum 52 is rotatably mounted on the support frame 51. The rotating drum 52 is sleeved on the outer side of the vertical section of the wire rope close to the winding drum 3, and the central axis of the rotating drum 52 coincides with the central axis of the vertical section of the wire rope; the surface cleaning component 53 includes a facial cleaning brush head 531 and a circumferentially rotating drive member 532. The facial cleaning brush head 531 is arranged on the inner side of the rotating drum 52, and the facial cleaning brush head 531 and the steel wire rope are connected. The outer side of the vertical section of the wire rope is in contact, and the bottom end of the cleansing brush head 531 is connected to the rotating drum 52 through a circumferentially rotating driving member 532. When the rotating drum 52 rotates, the circumferentially rotating driving member 532 drives the cleansing brush head 531 to rotate on itself and simultaneously rotate in a circle around the outer side of the vertical section of the wire rope; the driving end of the rotating drive assembly 54 is connected to the rotating drum 52 in a transmission manner, and is used to drive the rotating drum 52 to rotate on the support frame 51; the lubricant coating assembly 55 is located above the rotating drum 52, and is used to coat the outer side of the vertical section of the wire rope with lubricant.

[0043] It should be noted that when the above-mentioned maintenance mechanism 5 is adopted, in the process of winding the steel wire rope and lifting the lifting container 4, the rotating drum 52 is driven to rotate on the support frame 51 through the rotating drive component 54, and under the driving action of the circumferential rotating drive member 532, the facial cleaning brush head 531 can be driven to rotate, and at the same time, it can rotate in a circle around the outer side of the vertical section of the steel wire rope. Through the circumferential rotation of the facial cleaning brush head 531, it can evenly clean the outer side of the vertical section of the steel wire rope, and the attached dust and lubricant can be cleaned together. Through the rotation of the cleaning brush head, the cleaning surface of the facial cleaning brush head 531 at different positions can be in contact with the steel wire rope, and the powder adsorbed thereon can be removed by the centrifugal force generated by the rotation of the cleaning brush head. Dust and lubricant are thrown onto the inner wall of the rotating drum 52, realizing the self-cleaning function of the cleaning brush head and avoiding secondary pollution to the wire rope. Then, the vertical section of the cleaned wire rope continues to move upward to reach the position of the lubricant coating assembly 55, and the lubricant is re-applied to the wire rope to replenish the cleaned lubricant, thereby protecting the wire rope. In this way, through the special cleaning method of the cleaning brush head 531, not only can the automatic cleaning function of the wire rope be realized, but also the problem of dust causing wear to the wire rope and affecting its normal heat dissipation is solved. In addition, compared with the method of directly scraping the wire rope for cleaning, the friction between the rotating contact method and the dust is smaller, so the damage to the wire rope is also smaller.

[0044] Please refer to Figures 4 to 6 The circumferentially rotating driving member 532 includes a supporting base plate 5321, an inner gear ring 5322, a first gear 5323 and a second gear 5324. The supporting base plate 5321 is fixedly mounted on the lower end of the inner side of the rotating drum 52. The inner gear ring 5322 is located above the supporting base plate 5321, and its outer ring surface is fixedly connected to the inner side wall of the rotating drum 52. The bottom of the first gear 5323 penetrates downward through the supporting base plate 5321 and is fixed to one side of the supporting frame 51. An entry hole for the passage of a steel wire rope is provided at the center of the top surface of the first gear 5323. Both sides of the second gear 5324 are respectively meshed with the first gear 5323 and the inner gear ring 5322. A circular groove body 5325 is provided on the top surface of the supporting base plate 5321. The bottom of the first gear 5323 is slidably connected to the circular groove body 5325 through a connecting shaft. The top of the first gear 5323 is fixedly connected to the bottom of the facial cleansing brush head 531.

[0045] It should be noted that when the above-mentioned circumferentially rotating driving member 532 drives the facial cleansing brush head 531 to move, the rotating drum 52 rotates, and the inner gear ring 5322 rotates synchronously with the rotating drum 52. Since the first gear 5323 is fixed to the support frame 51, it will not rotate with the inner gear ring 5322, and the second gear 5324 begins to rotate in a circle around the outer side of the vertical section of the wire rope under the driving action of the inner gear ring 5322. At the same time, under the driving action of the first gear 5323, it can also rotate on its own, so that the facial cleansing brush head 531 can clean the outer side of the vertical section of the wire rope by self-rotation accompanied by circular rotation.

[0046] Please refer to Figure 6 The facial cleaning brush head 531 includes a mounting rod 5311 and three facial cleaning brushes 5312. The bottom end of the mounting rod 5311 is fixedly connected to the center of the top of the first gear 5323. The three facial cleaning brushes 5312 are evenly distributed on the outside of the mounting rod 5311. The facial cleaning brushes 5312 and the mounting rod 5311 can be detachably fixed by screws, which is convenient for replacement. The number of facial cleaning brushes 5312 is not limited to three and can be adjusted according to actual usage. The facial cleaning brush 5312 can be made of nylon. Setting multiple facial cleaning brushes 5312 can avoid the problem of severe wear of a single facial cleaning brush 5312 due to long-term contact with the wire rope.

[0047] Please refer to Figure 5 In the above scheme, the dust and lubricant adsorbed on the cleansing brush 5312 may be difficult to clean quickly due to the centrifugal force generated by the self-rotation of the cleansing brush 5312, and the brushed-out part will accumulate in the rotating drum 52, causing internal environmental pollution. Therefore, in order to solve this problem, the present invention further optimizes the above scheme. The specific scheme is as follows: the surface cleaning component 53 also includes a circular collection box 5326 and a cleaning plate 5327. The cleaning plate 5327 is fixedly mounted on the inner wall of the rotating drum 52. One end of the cleaning plate 5327 is provided with a comb groove adapted to the cleansing brush 5312. The cleaning plate 5327 is in the shape of an obtuse broken line as a whole. The collection box 5326 is located below the cleaning plate 5327, and its outer annular surface is fixed to the inner wall of the rotating drum 52.

[0048] It should be noted that when the cleaning brush head 531 cleans the vertical section of the wire rope, when the cleaning brush head 531 contacts the end of the cleaning plate 5327, due to the adaptive arrangement of the cleaning plate 5327 and the cleaning brush head 531, the outer side of the cleaning brush head 531 can smoothly pass through the comb tooth groove. During the passing process, the comb tooth groove can scrape off the dust attached to the outer side of the cleaning brush head 531, thereby further realizing the cleaning function of the cleaning brush 5312, and can enhance the self-cleaning effect of the cleaning brush 5312, and avoid secondary pollution to the wire rope, and the scraped dust and lubricant will flow downward along the cleaning plate 5327 to the collection box 5326 below, and the dust and lubricant thrown to the inner wall of the rotating drum 52 can also flow downward to the collection box 5326 by themselves, thereby avoiding dust and lubricant from polluting the internal environment of the rotating drum 52.

[0049] Please refer to Figures 7 and 8 The rotating drive assembly 54 is a matching transmission structure, which includes a protective shell 541, a fixed frame 542, a friction contact member 543 and a rotating transmission member 544. The protective shell 541 is located above the rotating drum 52 and is sleeved on the outer side of the vertical section of the wire rope. One side of the protective shell 541 is fixed to the top of the support frame 51 through the fixed frame 542. The friction contact member 543 is rotatably installed in the protective shell 541. One side of the friction contact member 543 contacts the outer side of the vertical section of the wire rope. The friction contact member 543 is connected to the rotating drum 52 through the rotating transmission member 544. When the wire rope is wound, the friction contact member 543 is driven to rotate by the upwardly moved vertical section of the wire rope, so that the rotating transmission member 544 drives the rotating drum 52 to rotate synchronously.

[0050] Specifically, the friction contact member 543 is two friction wheels 5431, which are symmetrically distributed on both sides of the vertical section of the wire rope. The outer ring of the friction wheel 5431 is provided with an annular groove 5432 adapted to the wire rope. The friction wheel 5431 can be made of rubber material, which can not only reduce the wear on the wire rope, but also has good wear resistance. The rotating transmission member 544 includes a matching gear 5441, a transmission rod 5442, a bevel gear 5443, a bevel gear ring 5444 and two transmission gears 5445. The two transmission gears 5445 are respectively fixedly connected to one side of the two friction wheels 5431. The matching gear 5441 is located between the two transmission gears 5445, and its two sides are respectively meshed with the two transmission gears 5445. The transmission rod 5442 is rotatably mounted on the fixed frame 542. One end of the transmission rod 5442 is fixedly connected to one side of the matching gear 5441. The bevel gear 5443 is fixedly sleeved on the other end of the transmission rod 5442. The bevel gear ring 5444 is fixedly sleeved on the upper end of the outer side of the rotating drum 52, and its outer side is meshed with the bevel gear 5443.

[0051] It should be noted that when the rotary drive assembly 54 is used to drive the drum 52 to rotate, during the upward movement of the vertical section of the wire rope, the two friction wheels 5431 rotate respectively under the driving action of the wire rope, and the two transmission gears 5445 rotate synchronously with the corresponding friction wheels 5431, and the matching gear 5441 rotates under the common driving action of the two transmission gears 5445, and the transmission rod 5442 and the bevel gear 5443 rotate together, and the rotation of the bevel gear 5443 can drive the bevel gear ring 5444 and the drum 52 to rotate together, so that the The rotating drum 52 rotates, and the rotating drive assembly 54 uses the force generated by the upward movement of the wire rope as the driving source, thereby realizing the coordinated transmission between the rotating drum 52 and the wire rope. In the process of the wire rope moving upward, the rotating drum 52 synchronously adapts to the rotation action. On the one hand, the rotation speed of the rotating drum 52 can be matched with the upward movement speed of the wire rope. On the other hand, it eliminates the need for a separate external driving source and the need for additional control program regulation, and its use cost is lower. In addition, the two friction wheels 5431 not only serve as a power source, but also can limit the wire rope in the upward movement process, so that it can be wound in a standard posture.

[0052] Please refer to Figures 9 to 12 After the dust and lubricant on the surface of the steel wire rope are cleaned by the above scheme, it is necessary to refill the lubricant to continue protecting the steel wire rope. The specific scheme is as follows: the lubricant coating assembly 55 includes a liquid storage box body 551, two liquid outlet pipes 552 and two control valve components 553. The liquid storage box body 551 can be detachably mounted on the top of the protective shell 541, and lubricant is stored therein. The two liquid outlet pipes 552 are both connected to one side of the liquid storage box body 551, and the bottom outlets of the two liquid outlet pipes 552 are respectively aligned with the tops of the two friction wheels 5431. The two control valve components 553 are respectively connected to the two liquid outlet pipes 552, which are used to control the liquid outlet pipes 552. Intermittent opening, the control valve component 553 includes a blocking slide bar 5531, a supporting spring 5532 and eight trigger blocks 5533. The blocking slide bar 5531 is slidably installed at the inlet end of the liquid outlet pipe 552, and the supporting spring 5532 is fixedly installed between the top of the blocking slide bar 5531 and the inner wall of the liquid outlet pipe 552. One side of the blocking slide bar 5531 is provided with a liquid inlet hole 5534 adapted to the inlet end of the liquid outlet pipe 552. The bottom end of the blocking slide bar 5531 slides downward and extends to the bottom of the liquid outlet pipe 552. The eight trigger blocks 5533 are evenly distributed on one side of the friction wheel 5431. One side of the trigger block 5533 is provided with an inclined surface adapted to the blocking slide bar 5531.

[0053] It should be noted that when the lubricant coating assembly 55 is used to coat the vertical section of the wire rope with lubricant, in the initial state, the blocking slide bar 5531 blocks the inlet end of the liquid outlet pipe 552, so that the lubricant in the liquid storage box body 551 will not enter the liquid outlet pipe 552. When the wire rope moves upward, the friction wheel 5431 is driven by the wire rope to rotate. When the inclined surface of one of the trigger blocks 5533 contacts the bottom end of the blocking slide bar 5531, an upward thrust is generated on the blocking slide bar 5531, and the blocking slide bar 5531 extends inside the liquid outlet pipe 552 and simultaneously squeezes the support spring 5532 to contract. When the top end of the trigger block 5533 moves and contacts the bottom end of the blocking slide bar 5531, the sealing The blocking slide bar 5531 is pushed to the highest position, at which time the liquid inlet hole 5534 is connected to the inlet end of the liquid outlet pipe 552, so that the lubricant in the liquid storage box body 551 can flow into the liquid outlet pipe 552 and finally drip downward onto the friction wheel 5431 below. Then, the friction wheel 5431 continues to rotate, and the trigger block 5533 is separated from the blocking slide bar 5531. Under the elastic force of the supporting spring 5532, the blocking slide bar 5531 can be moved down and reset to block the inlet end of the liquid outlet pipe 552 again. The lubricant no longer flows into the liquid outlet pipe 552 until the next trigger block 5533 contacts the blocking slide bar 5531, and the lubricant flows into the liquid outlet pipe 552 again. In this way, the lubricant can be controlled. The lubricant flows into the liquid outlet pipe 552 in an intermittent amount, and then contacts the vertical section of the wire rope through the friction wheel 5431, and the lubricant is coated on its outer side, thereby realizing the automatic lubricant coating function for the wire rope. In the process of the vertical section of the wire rope moving downward, the rotation direction of the friction wheel 5431 is opposite to that when moving upward. At this time, the other side of the trigger block 5533 contacts the bottom end of the blocking slide bar 5531. Since this side is a vertical surface, it will not generate a downward thrust on the blocking slide bar 5531. Therefore, at this time, the friction wheel 5431 is locked and cannot rotate with the wire rope, and the liquid outlet pipe 552 is always blocked, so that the lubricant will not flow out. Since the friction between the friction wheel 5431 and the wire rope is much smaller than The downward force of the wire rope will not cause a significant degree of hindrance to the downward movement of the wire rope. In this way, when the wire rope moves downward, the lubricant coating component 55 will not continue to coat the wire rope. Since the lubricant has just been replenished when the wire rope moves up, there is no need to apply lubricant when the wire rope moves downward, thereby avoiding waste of lubricant. It can be seen that the lubricant coating component 55 provided in the present invention, by being used in conjunction with the above-mentioned matching transmission structure, can not only realize the function of automatically replenishing lubricant to the wire rope after it is cleaned, but also can automatically choose whether to apply lubricant according to the moving state of the wire rope, and its coating speed can synchronously adapt to the moving speed of the wire rope without the need for manual or program control adjustment.

[0054] Embodiment 2

[0055] Please refer to Fig. 9As another embodiment of the present invention, the main difference from the first embodiment is that the rotation drive component 54 is an active drive structure, which includes a drive motor 545, a driving gear 546 and a passive gear ring 547. The drive motor 545 is fixedly mounted on the support frame 51, the driving gear 546 is fixed to the rotating end of the drive motor 545, and the passive gear ring 547 is fixedly sleeved on the upper end of the outer side of the rotating drum 52, and one side of the passive gear ring 547 is meshed with the driving gear 546.

[0056] It should be noted that when the active driving structure drives the drum 52 to rotate, the driving motor 545 rotates, so that the active gear 546 drives the passive gear ring 547 to rotate, and finally the drum 52 rotates.

[0057] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
