Description

Technical Field

[0001] The invention relates to the technical field of hoists, and in particular to a motor-installed mine hoist. Background Art

[0002] Mine hoist is a working machine in the mine and on the ground. It is a large winch. It uses wire ropes to drive containers (cages or buckets) up and down in the shaft to complete the task of transporting materials and personnel. Mine hoists have gradually evolved from primitive water-lifting tools. Modern mine hoists have large lifting capacity and high speed, and have developed into fully automatic heavy mining machinery controlled by electronic computers.

[0003] The Chinese patent with the authorization announcement number CN118387790B discloses a winch assembly, which belongs to the technical field of drilling rig auxiliary equipment. It includes: a base, two support seats, a motor and a reduction box are fixedly installed on the top of the base, the same rotating shaft is rotatably installed on the two support seats, a reel is fixedly sleeved on the rotating shaft, a wire rope is wound on the reel, the output end of the motor is connected to the input end of the reduction box, and the output end of the reduction box is connected to one end of the rotating shaft, the two retaining rings of the reel are fixedly sleeved with brake discs, and the outer walls of both sides of the two support seats are fixedly installed with hydraulic oil brakes that match the brake discs, two first slide bars are installed on the base, and the sliding sleeves on the two first slide bars are provided with moving seats, and the top of the moving seat is installed with a first wheel frame. The winch assembly provided by the patent has the advantages of being able to scrape off the debris adhered to the wire rope during the process of pulling the heavy object, which is conducive to making the wire rope winding more compact and regular, with a wide range of applicable occasions and convenient use.

[0004] The above scheme scrapes off the mud or other impurities adhered to the wire rope by setting up a scraper box and other structures. However, the wire rope is made of twisted steel wires and has an uneven surface. It is difficult for the scraper device to clean the impurities on the surface of the wire rope. The scraped impurities may also stick to the concave surface. In particular, after the lubricating oil on the surface of the wire rope is mixed with the impurities, the impurities are more difficult to peel off, causing the wire ropes to become adhered to each other, making it difficult to achieve a compact and regular winding effect. Summary of the invention

[0005] The present invention provides a motor-mounted mine hoist, which aims to solve the technical problem that mud or other impurities adhered to a steel wire rope are scraped off by a scraper box and other structures in the related art. However, the steel wire rope is twisted from steel wires, and its surface is uneven. It is difficult for the scraper device to clean the impurities on the surface of the steel wire rope, and the scraped impurities may also stick to the concave surface. In particular, after the lubricating oil on the surface of the steel wire rope is mixed with the impurities, the impurities are more difficult to peel off, so that the steel wire ropes become adhered to each other, making it difficult to achieve a compact and regular winding effect.

[0006] A motor-mounted mine hoist of the present invention comprises a base, a drum, a wire rope, a guide frame and a guide wheel. A plurality of cleaning modules are arranged on the guide frame, and each cleaning module comprises a guide unit and a cleaning unit. The guide unit comprises a threading tube fixedly arranged on the guide frame, the threading tube is used for the wire rope to pass through, and the threading tube is provided with two through holes along its axial direction, the two through holes are distributed front and back, and the two through holes are both located on the same horizontal plane where the axis of the threading tube is located, and a spiral installation groove is arranged on the inner wall of the threading tube, and the two ends of the installation groove pass through the two through holes respectively, and the installation groove is connected with the threading tube passing through The spiral direction of the wire rope is consistent; the cleaning unit includes a mounting frame fixed to the guide frame, and rollers are rotatably mounted on the mounting frame front and back, the planes in which the axes of the two rollers are located are parallel to the axis of the threading tube, and there is an angle between the axes of the rollers and the axis of the threading tube, one of the rollers is wound with a belt, and the belt is provided with bristles, one end of the belt passes through the mounting groove and is connected to the other roller, the belt and the mounting groove are slidably matched, and a driving component is also provided on the mounting frame to drive the two rollers to rotate in the same direction and at the same time, so that the belt is alternately wound on the two rollers, and the bristles can clean the wire rope when the belt passes through the mounting groove.

[0007] Beneficial effect: As the first roller and the second roller continuously pull the tape to reciprocate, the bristles on the spiral tape located in the threading tube will continuously brush the moving wire rope. Since the spiral direction of the spiral bristles is consistent with the spiral direction of the wire rope, the bristles can not only clean up impurities on the surface of the wire rope, but also bring out impurities in the spiral grooves of the wire rope, thereby effectively cleaning the impurities on the wire rope.

[0008] Preferably, cleaning rollers are rotatably installed on the front and rear sides of the threading tube, the axes of the cleaning rollers are parallel to the axis of the threading tube, the cleaning rollers on the front and rear sides are correspondingly distributed at the positions of the front and rear perforations of the threading tube, and spiral strips are fixedly installed on the outer walls of the cleaning rollers.

[0009] The effect is that when the tape passes through the perforation, the bristles on the tape will contact the rotating spiral strips, so that the spiral strips can scrape off the impurities on the bristles, completing the cleaning of the bristles. As the cleaning roller rotates rapidly, the impurities on the spiral strips can be thrown off. In addition, after the bristles contact the cleaning roller, as the bristles move forward, the cleaning roller will push the bristles to make them inclined. When the bristles pass over the cleaning roller, the bristles will quickly reset, so that the bristles have a rapid ejection action, which can further throw off the impurities on the bristles and improve the cleaning effect.

[0010] Preferably, a driving wheel and a driven wheel are fixedly mounted on the two rollers respectively, and the driving wheel and the driven wheel are connected by a transmission belt.

[0011] Preferably, the driving wheel and the driven wheel are both synchronous wheels, and the transmission belt is a synchronous belt.

[0012] The effect is that the synchronous rotation of the first roller and the second roller can be ensured, thereby ensuring that the tape is stably and alternately wound on the two rollers.

[0013] Preferably, a screw is rotatably installed on the base, the axis of the screw is horizontally arranged in the front-to-back direction, the guide frame is threadedly connected to the screw, and the guide frame and the base are horizontally slidably matched, so that when the screw rotates, the guide frame can be driven to move forward and backward, and the guide wheel is rotatably installed on the guide frame.

[0014] The effect is that when the wire rope is wound up, the lead screw drives the guide frame and the guide wheel to move forward and backward continuously, thereby guiding the wire rope to be evenly wound on the drum.

[0015] Preferably, the threading tube is arranged at an angle, and its axis is arranged along the left-right direction.

[0016] Preferably, the angle between the axis of the winding roller and the axis of the threading tube is 30-60 degrees.

[0017] The effect is that, in order to facilitate the tape to adapt to the spiral installation groove, the cleaning portion on the tape is finally made to have a spiral structure.

[0018] Preferably, the bristles are made of nylon.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. When the first roller and the second roller continuously pull the tape to reciprocate, the bristles on the spiral tape located in the threading tube will continuously brush the moving wire rope. Since the spiral direction of the spiral bristles is consistent with the spiral direction of the wire rope, the bristles can not only clean the impurities on the surface of the wire rope, but also bring out the impurities in the spiral grooves of the wire rope, which can effectively clean the impurities on the wire rope.

[0020] 2. When the tape passes through the perforation, the bristles on the tape will contact the rotating spiral strips, so that the spiral strips can scrape off the impurities on the bristles and complete the cleaning of the bristles. As the cleaning roller rotates rapidly, the impurities on the spiral strips can be thrown off. In addition, after the bristles contact the cleaning roller, as the bristles move forward, the cleaning roller will push the bristles to make them tilted. When the bristles pass over the cleaning roller, the bristles will quickly reset, making the bristles have a rapid ejection action, which can further throw off the impurities on the bristles and improve the cleaning effect.

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 10 As shown, a specific embodiment of a motor-mounted mine hoist of the present invention includes a base 10, a winding module, a guiding module, a cleaning module and a clearing module.

[0034] like Figure 1 As shown, the base 10 is a rectangular structure. In this embodiment, the length direction of the base 10 is defined as the left-right direction, and the width direction of the base 10 is defined as the front-back direction.

[0035] The winding module includes a reel 11 rotatably mounted on a base 10. The reel 11 is located near the left side of the base 10, and the reel 11 rotates along an axis extending in the front-to-back direction. A motor (not shown in the figure) is installed inside the reel 11. A reduction box 12 fixed to the base 10 is installed on the rear side of the reel 11, and the reduction box 12 is connected to the reel 11 in a transmission manner. A steel wire rope 13 is wound around the reel 11, and when the reel 11 rotates, the steel wire rope 13 can be wound or unwound. The above structures all belong to the prior art and will not be described in detail here.

[0036] like Figure 2 As shown, the guide module includes a lead screw 20 rotatably mounted on a base 10. The base 10 has a through hole extending vertically near the right side. The lead screw 20 is rotatably mounted in the through hole, and the axis of the lead screw 20 is arranged horizontally along the front-back direction. A motor driving the lead screw 20 to rotate is installed at the end of the lead screw 20, and the lead screw 20 is a reciprocating lead screw.

[0037] A guide frame 21 is screwed onto the lead screw 20, and the guide frame 21 and the base 10 are horizontally slidably matched, so that when the lead screw 20 rotates, the guide frame 21 can be driven to slide back and forth. A bracket 23 is fixedly installed on the upper surface of the guide frame 21. A guide wheel 22 is rotatably installed on the left end of the guide frame 21, and the axis of the guide wheel 22 is parallel to the axis of the lead screw 20. The wire rope 13 on the drum 11 passes around the guide wheel 22 and then goes vertically downward, and the end of the wire rope 13 located at the bottom is fixedly connected to a container. When the wire rope 13 is wound, the lead screw 20 drives the guide frame 21 and the guide wheel 22 to move back and forth continuously, thereby guiding the wire rope 13 to be evenly wound on the drum 11.

[0038] like Figures 3 to 10 As shown, in this embodiment, two groups of cleaning modules are provided. In other embodiments, three, five or even more groups of cleaning modules may be provided.

[0039] Each group of cleaning modules includes a guiding unit and a cleaning unit.

[0040] like Figures 3 to 6 As shown, the guide unit includes a threading tube 40 fixedly mounted on the bracket 23, the axis of the threading tube 40 is arranged in the left-right direction, and the threading tube 40 is inclined, and the left end of the threading tube 40 is higher than the right end. The wire rope 13 passes through the inner side of the threading tube 40. That is, the wire rope 13 passes through the threading tube 40 after passing through the guide wheel 22, and finally winds on the reel 11.

[0041] The threading tube 40 is provided with a first through hole 41 and a second through hole 42 along its axis, wherein the first through hole 41 is located at the front side and the second through hole 42 is located at the rear side. The first through hole 41 and the second through hole 42 are both located on the same horizontal plane where the axis of the threading tube 40 is located.

[0042] The inner wall of the threading tube 40 is provided with a mounting groove 43, which is spiral-shaped, and one end of the mounting groove 43 passes through the first through hole 41, and the other end of the mounting groove 43 passes through the second through hole 42. That is, one end of the mounting groove 43 enters the threading tube 40 from one through hole, and then spirals along the inner wall of the threading tube 40 for one circle and then passes through the other through hole. It is particularly noted that the spiral direction of the mounting groove 43 is consistent with the spiral direction of the steel wire rope 13 passing through the threading tube 40.

[0043] like Figure 3 , Figure 7 , Figure 8 , Fig. 9 as well as Fig.10 As shown, the cleaning unit includes a mounting frame 30 fixedly mounted on the bracket 23, and the mounting frame 30 corresponds to the position of the threading tube 40. The mounting frame 30 is rotatably mounted with a first roller 31 and a second roller 32 on the front and rear sides, respectively, and the axes of the first roller 31 and the second roller 32 are parallel to each other and are on the same plane.

[0044] The planes where the axes of the first roller 31 and the second roller 32 are located are parallel to the axis of the threading tube 40, and there is an angle (such as Figure 7 As shown), and the included angle range is between 30-60 degrees.

[0045] The first roller 31 and the second roller 32 simultaneously roll up the same belt 33, that is, one end of the belt 33 is fixed to the first roller 31, and the other end is fixed to the second roller 32. One side of the belt 33 is covered with bristles 34, the belt 33 is made of rubber, and the bristles 34 are made of nylon.

[0046] A driving wheel 35 is fixedly mounted on the second roller 32, and a driven wheel 36 is fixedly mounted on the first roller 31, and the driving wheel 35 and the driven wheel 36 are connected by a transmission belt 37, so that the first roller 31 and the second roller 32 can rotate in the same direction. It is particularly noted that in this embodiment, the driving wheel 35 and the driven wheel 36 are both synchronous wheels, and the transmission belt 37 is a synchronous belt, which ensures the synchronous rotation of the first roller 31 and the second roller 32.

[0047] The mounting frame 30 is provided with a motor connected to the first roller 31, so as to drive the first roller 31 and the second roller 32 to rotate simultaneously. When the first roller 31 and the second roller 32 rotate simultaneously and in the same direction, the rotation of the first roller 31 and the second roller 32 is controlled by the forward and reverse rotation of the motor, so that the tape 33 is alternately wound between the first roller 31 and the second roller 32. That is, when the first roller 31 is wound, the second roller 32 is unwound, and the tape 33 is finally wound on the first roller 31. Conversely, when the first roller 31 is unwound, the second roller 32 is wound, and the tape 33 is finally wound on the second roller 32, and the cycle continues.

[0048] The tape 33 passes through the first through hole 41 and the second through hole 42 at the same time, and the tape 33 is slidably fitted in the installation groove 43, that is, the portion of the tape 33 located in the threading tube 40 is spiral, and the tape 33 is closely attached to the inner wall of the threading tube 40. The installation groove 43 plays a role in shaping and fixing the tape 33. The bristles 34 on the tape 33 are all facing the steel wire rope 13, and the ends of the bristles 34 are in contact with the steel wire rope 13 (such as Fig.10 ).

[0049] When the first roller 31 and the second roller 32 continuously pull the take-up belt 33 to reciprocate, the bristles 34 on the spiral take-up belt 33 located in the threading tube 40 will continuously brush the moving wire rope 13. Since the spiral direction of the spiral bristles 34 is consistent with the spiral direction of the wire rope 13, the bristles 34 can not only clean up the impurities on the surface of the wire rope 13, but also bring out the impurities in the spiral grooves of the wire rope 13, thereby effectively cleaning the impurities on the wire rope 13.

[0050] It is particularly emphasized that the strips 33 on the first roll 31 and the second roll 32 are staggered (eg Figure 7 As shown), this allows for better access to the first through hole 41 or the second through hole 42, that is, to facilitate the tape 33 to adapt to the spiral mounting groove 43, and ultimately to make the cleaning portion on the tape 33 present a spiral structure, the purpose of setting an angle between the axis of the first roller 31 or the second roller 32 and the axis of the threading tube 40 is also the same.

[0051] Continue back Figure 4 and Figure 5 The cleaning module includes a cleaning roller 51 and a spiral strip 52 .

[0052] Cleaning rollers 51 are rotatably mounted on both the front and rear sides of the threading tube 40 , and the cleaning rollers 51 on both the front and rear sides are correspondingly distributed at the positions of the front and rear perforations of the threading tube 40 . The axis of the cleaning roller 51 is parallel to the axis of the threading tube 40 .

[0053] In this embodiment, two threading tubes 40 are taken as an example, and two cleaning rollers 51 are provided on both the front and rear sides of the threading tubes 40, and the two cleaning rollers 51 on each side are coaxially arranged and fixedly connected. The threading tubes 40 are fixedly connected with side plates 50, and the cleaning rollers 51 are rotationally matched with the side plates 50, and the cleaning rollers 51 are rotationally matched with the brackets 23 to ensure the stability of the cleaning rollers 51. The side plates 50 are installed with motors that drive the cleaning rollers 51 to rotate.

[0054] Spiral strips 52 are fixedly installed on the outer surface of the cleaning roller 51. When the belt 33 passes through the perforation, the bristles 34 on the belt 33 will contact the rotating spiral strips 52, so that the spiral strips 52 can scrape off the impurities on the bristles 34, completing the cleaning work of the bristles 34. As the cleaning roller 51 rotates rapidly, the impurities on the spiral strips 52 can be thrown off.

[0055] In addition, after the bristles 34 contact the cleaning roller 51, as the bristles 34 move forward, the cleaning roller 51 will push the bristles 34 to make it inclined. As the bristles 34 move forward, when the bristles 34 pass over the cleaning roller 51, the bristles 34 will quickly reset, that is, the bristles 34 will have a rapid ejection action, which can further shake off the impurities on the bristles 34 and improve the cleaning effect.

[0056] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
