Description
Technical Field
[0001] The utility model relates to the technical field of cable winding and unwinding equipment for a bunker cleaner, and particularly relates to a cable winding and unwinding device for a mine bunker cleaner. Background Technique
[0002] A mine bunker cleaner is an efficient mine dredging device. It adopts advanced automatic control technology, which can significantly improve the efficiency and safety of the bunker dredging work. Through mechanized operation, the mine bunker cleaner can quickly remove sediment impurities such as coal slime in the bunker, greatly improving the dredging efficiency. It has the advantages of strong adaptability, remote operation, and remarkable environmental protection benefits. It can operate flexibly according to the actual situation of different mines, reducing the manpower requirement, improving the operation environment, and ensuring the safety and smoothness of mine operation.
[0003] However, due to the long length of the underground bunker, a long cable is required for power transmission during the production operation of the mine bunker cleaner, which is likely to cause the cable to drag on the ground or be dragged, and the cable is dragged into the water and coal slime, making the surface of the cable adhere to coal slime. When the cable is wound around the winding drum, the coal slime between the cables will coagulate together, resulting in cable unreeling failures. Moreover, directly winding the cable around the winding drum will also make the cable arrangement irregular, causing entanglement and friction between the cables, easily leading to damage to the insulation skin outside the cable and affecting the quality of the cable. Therefore, the technical personnel in this field provide a cable winding and unwinding device for a mine bunker cleaner to solve the problems raised in the above background technique. Content of the Utility Model

[0013] Compared with the prior art, the advantages of the present utility model are as follows:
[0014] By sequentially arranging a guiding mechanism and a cleaning mechanism on one side of the take-up roller, when winding the cable, the cable can first pass through between the fixed seat and the end plate. The brushes installed on the upper end face of the fixed seat and the lower end plate of the end plate surround the outside of the cable to clean the slime on the cable surface.

[0021] Combined with Figure 1 , Figure 2 and Figure 4 As shown, a winding roller 11 for winding the cable is provided on the retractable frame 1. A guiding mechanism 2 and a cleaning mechanism 3 are sequentially arranged on one side of the winding roller 11. Among them, the guiding mechanism 2 includes a transmission seat 21. Inside the transmission seat 21, two positioning slide rods 211 are symmetrically distributed. A support plate 221 is provided at the bottom of the driving plate 22. First sliding holes 222 are provided at the positions corresponding to the two positioning slide rods 211 on the end face of the support plate 221. The support plate 221 slides on the outer walls of the two positioning slide rods 211 through the first sliding holes 222. And, a lead screw 26 is arranged between the two positioning slide rods 211 inside the transmission seat 21. A threaded hole 223 is opened at the position corresponding to the lead screw 26 on the end face of the support plate 221. The support plate 221 is threadedly installed on the outer wall of the lead screw 26 through the threaded hole 223, and the support plate 221 can slide on the outer walls of the positioning slide rods 211 by the rotation of the lead screw 26. A motor 25 for driving the forward and reverse rotation of the lead screw 26 is arranged on one side of the transmission seat 21. And, a supporting wheel 23 for stretching the cable is rotatably installed at the middle position of the upper end face of the driving plate 22. Pressing wheels 24 for limiting the position of the cable are rotatably installed on both sides of the supporting wheel 23. The cable sequentially passes through the pressing wheels 24, the supporting wheel 23 and the pressing wheels 24 and is wound on the winding roller 11.
[0022] In one embodiment, when winding the cable on the winding roller 11, the cable can be pulled by the rotating winding roller 11 and sequentially pass through the brush 35, the pressing wheels 24, the supporting wheel 23 and the pressing wheels 24 and enter the winding roller 11 and be wound on the winding roller 11. The cable wound on the winding roller 11 is pressed and stretched by the two pressing wheels 24 and the supporting wheel 23 distributed in a triangular shape, preventing the cable entering and wound on the winding roller 11 from being in a loose state and ensuring the quality of cable winding.
[0023] In one embodiment, when arranging the cable on the take-up roller 11, the motor 25 can be driven to work, driving the lead screw 26 installed at its output end to rotate forward and backward, and driving the support plate 221 installed on the outer wall of the lead screw 26 through the threaded hole 223 to displace. The support plate 221 reciprocates on the outer wall of the positioning slide bar 211 through the first slide hole 222. Then, the reciprocating support plate 221 drives the driving plate 22 connected thereto to reciprocate on the transmission seat 21, and drives the supporting roller 23 and the two pressing rollers 24 installed thereon to displace, adjusting the position of the cable wound around the supporting roller 23 and the pressing rollers 24, arranging the cable evenly on the take-up roller 11 for winding, preventing the cable from being entangled on the take-up roller 11, avoiding the trouble that the insulating sheet on its surface is damaged due to the entanglement and friction of the cable on the take-up roller 11, ensuring the integrity and quality of the cable, prolonging the service life of the cable, and having strong practicability.
[0024] In one embodiment, when adjusting the position of the driving plate 22, the positioning slide bar 211 can limit the support plate 221 and the driving plate 22, preventing the support plate 221 and the driving plate 22 from rotating along with the rotation of the lead screw 26, avoiding the situation that the support plate 221 and the driving plate 22 cannot drive the supporting roller 23 and the pressing rollers 24 to reciprocate due to their rotation along with the lead screw 26, and ensuring the progress of the position adjustment work of the driving plate 22.
[0025] Combined Figure 1 and Figure 3 As shown, the cleaning mechanism 3 includes a fixed seat 31 and an end plate 32. The end plate 32 is arranged above the fixed seat 31. Moreover, brush hairs 35 are arranged on the upper end surface of the fixed seat 31 and the lower end surface of the end plate 32. The two brush hairs 35 are in mutual contact. And limit slide bars 33 are arranged on both sides of the brush hairs 35 on the upper end surface of the fixed seat 31. The limit slide bars 33 penetrate through the end plate 32 and extend above it. And an annular limit plate 331 is arranged at one end of the limit slide bar 33 above the end plate 32. A spring 34 is arranged between the lower end surface of the annular limit plate 331 and the upper end surface of the end plate 32 and around the outside of the limit slide bar 33.
[0026] In one embodiment, when cleaning the cable, the cable can be passed through between the fixed seat 31 and the end plate 32. The two brush hairs 35 installed on the upper end surface of the fixed seat 31 and the lower end surface of the end plate 32 surround the outside of the cable to clean the coal slime on the surface of the cable, preventing the coal slime on the surface of the cable wound around the take-up roller 11 from coagulating with each other, avoiding the situation that the cable fails due to the coagulation of the coal slime adhered to the surface of the cable, and ensuring the progress of the cable outgoing work.
[0027] In one embodiment, when using the brush 35 to clean the slime on the surface of the cable, the end plate 32 can slide on the outer wall of the limit slide bar 33 through the second slide hole 321 under the elastic force of the spring 34, and drive the brush 35 located above to move downward and press tightly on the brush 35 located below, so that the two brushes 35 are closely attached to each other and surround the outside of the cable, preventing gaps from appearing between the two brushes 35, avoiding the situation where part of the surface of the cable is not cleaned due to the gaps between the two brushes 35, improving the cleaning effect of the cable surface, and having strong practicability.
[0028] In one embodiment, since the upper end surface of the fixed seat 31 is flush with the upper end surface of the drive plate 22, when winding up the cable after cleaning, the cable after cleaning can be wound around the pressing wheel 24 and the supporting wheel 23 in sequence. The supporting wheel 23 and the pressing wheel 24 tighten and limit the cable, and the cable will not interfere with the fixed seat 31, the transmission seat 21, and the drive plate 22, avoiding the situation where the cable is damaged by friction due to interference between the cable and the fixed seat 31, the transmission seat 21, and the drive plate 22, realizing the protection of the cable and ensuring the cable winding work.
[0029] The working principle of the present utility model is as follows: When winding the cable, the cable can be pulled by the rotating winding roller 11 and sequentially pass through the brush 35, the pressing wheel 24, the supporting wheel 23 and the pressing wheel 24 to enter the winding roller 11 and wind around the winding roller 11. First, two brushes 35 distributed vertically surround the outside of the cable to clean the coal slime on the surface of the cable, preventing the coal slime on the surface of the cable wound on the winding roller 11 from coagulating with each other. Then, two pressing wheels 24 and the supporting wheel 23 distributed in a triangular pattern press and stretch the cable entering the winding roller 11 to prevent the cable entering and winding on the winding roller 11 from becoming loose. At the same time, the driving motor 25 is driven to work to drive the lead screw 26 installed at its output end to rotate forward and backward, and drive the support plate 221 installed on the outer wall of the lead screw 26 through the threaded hole 223 to displace. The support plate 221 reciprocates on the outer wall of the positioning slide bar 211 through the first sliding hole 222. Then, the reciprocating support plate 221 drives the driving plate 22 connected thereto to reciprocate on the transmission seat 21, and drives the supporting wheel 23 and the two pressing wheels 24 installed thereon to displace, adjusting the position of the cable wound on the supporting wheel 23 and the pressing wheel 24, and thus completing the arrangement and winding of the cable. It can clean the coal slime on the surface of the cable and evenly arrange the cleaned cable on the winding roller 11, preventing the cables on the winding roller 11 from entangling and rubbing against each other. This not only avoids the occurrence of cable failures caused by the coagulation of the coal slime adhered to the surface of the cable, but also avoids the trouble of the insulation sheet on the surface of the cable being damaged due to the entanglement and friction of the cables on the winding roller 11, ensuring the integrity and quality of the cable, extending the service life of the cable, reducing the later maintenance cost of the cable, providing a reliable power supply guarantee for the continuous and efficient operation of the mine, and having strong practicability.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
