Description
Technical Field
[0001] This utility model relates to the technical field of mine hoist maintenance equipment, specifically a mine hoist gate plate cleaning device. Background Technology
[0002] In modern mining operations, mine hoists are key transportation equipment, undertaking the task of vertical transportation of personnel, ore and materials. As the core component of the braking system, the hoist's brake disc is prone to accumulating dirt such as coal dust, slag and oil during long-term operation, thus requiring cleaning.
[0003] Traditional methods of cleaning mine hoist gates mainly rely on manual operation. Workers need to manually use tools such as brushes and cleaning agents to scrub the gates. This method not only consumes a lot of manpower and time, but also has low cleaning efficiency. Moreover, due to the harsh working environment in mines, such as narrow spaces, high dust concentrations, and poor lighting conditions, workers face high safety risks during manual cleaning, such as slipping and falling, and occupational diseases caused by inhaling dust. In addition, manual cleaning is difficult to guarantee the uniformity and thoroughness of cleaning, and it is easy to have cleaning dead spots, which cannot meet the requirements of modern mines for high-precision maintenance of hoist equipment.
[0004] While some cleaning devices exist on the market, some have limitations in their functional design. Although some devices can perform simple brushing or vacuuming, they cannot achieve simultaneous rinsing and brushing. The mine environment is complex, and the dirt on the gate discs is diverse. Simple brushing or vacuuming is insufficient to completely remove all impurities, and the lack of rinsing function makes it impossible to wash away the brushed dirt in time, which can easily cause secondary pollution and affect the cleaning quality. With the continuous expansion of mining scale and the advancement of intelligent production, the development of an efficient, safe, and automated mine hoist gate disc cleaning device has become an urgent problem to be solved in the industry.

[0016] In a preferred embodiment, the two fixed plates are fixed on the top surface of the working plate near the left and right ends. The brushing mechanism also includes two rotating columns that are rotatably connected to the two fixed plates respectively, a drive motor installed on the outer wall of one of the fixed plates and whose output shaft is coaxially connected to the rotating column on the same side, the bidirectional lead screw is coaxially fixed between the two rotating columns, and the two moving rods are symmetrically arranged on the outer circumference of the bidirectional lead screw.
[0017] In a preferred embodiment, a vertically arranged rotating roller is rotatably connected between the two horizontal ends of the U-shaped plate. The brush roller is coaxially fixed on the outer circumferential wall of the rotating roller on the same side. The output shaft of the cleaning motor is coaxially connected to the rotating roller on the same side.

[0035] The matrix arrangement of support columns 11 at the bottom of the working plate 1 and the anti-slip texture at the bottom of the support plate 12 make the device more stable. The matrix arrangement enhances the uniformity of force distribution, and the anti-slip texture increases friction, reducing the impact of vibration and improving the stability of the device even on wet or uneven ground.
[0036] In this embodiment, as Figures 1-2 As shown, it also includes: a flushing mechanism 4, which is set on the outer wall of the vertical plate 3 and is used to flush the left and right surfaces of the gate body 2. The flushing mechanism 4 includes a nozzle 43 located above the gate body 2 and a pump body 41 installed on the outer wall of the vertical plate 3 and used to supply water to the nozzle 43.
[0037] The top surface of the horizontal plate end of the vertical plate 3 is provided with a through hole. The water pipe 42 is L-shaped. The vertical end of the water pipe 42 is fixed in the through hole on the top surface of the horizontal plate end of the vertical plate 3. The parts of the water pipe 42 that contact the pump body 41 and the nozzle 43 are provided with sealing rings.

[0039] The water circuit is tightly connected by the through holes at the ends of the vertical and horizontal plates 3, the L-shaped water pipe 42, and the sealing ring. The through holes fix the water pipe 42, the L-shaped design optimizes the layout, and the sealing ring prevents water leakage, ensuring stable water flow during the flushing process and avoiding water waste and equipment moisture.
[0040] In addition, such as Figure 1 , Figures 3-4As shown, it also includes: a brushing mechanism 5, which is set on the top surface of the working plate 1 and is used to brush the left and right disc surfaces of the gate body 2. The brushing mechanism 5 includes two fixed plates 51 fixed on the top surface of the working plate 1, a bidirectional lead screw 53 rotatably connected between the two fixed plates 51, two moving rods 55 threadedly connected to the bidirectional lead screw 53, two U-shaped plates 59 located on the front side of the moving rods 55 on the same side, and two electric cylinders 510 respectively installed on the outer wall of the two moving rods 55 and respectively used to drive the two U-shaped plates 59 to move. A brush roller 512 is rotatably connected between the two horizontal plate ends of the U-shaped plate 59, and a cleaning motor 513 for driving the brush roller 512 on the same side to rotate is installed on the outer wall of the U-shaped plate 59.
[0041] Two fixed plates 51 are fixed on the top surface of the working plate 1 near the left and right ends. The brushing mechanism 5 also includes two rotating columns 52 that are rotatably connected to the two fixed plates 51 respectively, a drive motor 54 installed on the outer wall of one of the fixed plates 51 and whose output shaft is coaxially connected to the rotating column 52 on the same side, a bidirectional lead screw 53 coaxially fixed between the two rotating columns 52, and two moving rods 55 symmetrically arranged on the outer circumference of the bidirectional lead screw 53.
[0042] The brushing mechanism 5 achieves lateral movement of the brush roller 512 via the fixed plate 51, rotating column 52, drive motor 54, bidirectional lead screw 53, and moving rod 55 on the top surface of the working plate 1. The drive motor 54 drives the bidirectional lead screw 53 to rotate, and the moving rod 55 moves synchronously to ensure that every area of the disc surface is effectively brushed.
[0043] A vertically arranged rotating roller 511 is rotatably connected between the two horizontal ends of the U-shaped plate 59. A brush roller 512 is coaxially fixed on the outer circumference of the rotating roller 511 on the same side. The output shaft of the cleaning motor 513 is coaxially connected to the rotating roller 511 on the same side. The cylinder body of the electric cylinder 510 is installed on the front surface of the moving rod 55 on the same side. The piston rod of the electric cylinder 510 is fixed on the rear surface of the vertical end of the U-shaped plate 59 on the same side. A telescopic rod 58 is fixed on the front surface of the moving rod 55, and a telescopic rod 58 that is slidably inserted into the sleeve 57 on the same side is fixed on the rear surface of the vertical end of the U-shaped plate 59.
[0044] The brush roller 512, cleaning motor 513, electric cylinder 510, sleeve 57, and telescopic rod 58 on the U-shaped plate 59 allow for flexible adjustment of the brush roller 512, control of the distance by the electric cylinder 510, drive of the cleaning motor 513, and ensure of smooth movement by the telescopic rod 58, thus achieving efficient brushing that fits the disc surface.
[0045] The top surface of the working plate 1 is provided with a guide groove arranged horizontally, and the bottom surface of the moving rod 55 is fixed with a guide block 56 that is slidably connected to the guide groove on the top surface of the working plate 1;
[0046] The guide groove on the top surface of the working plate 1 and the guide block 56 on the bottom surface of the moving rod 55 make the movement of the moving rod 55 more stable. The guide groove limits the direction of movement, and the guide block 56 cooperates with it to prevent the moving rod 55 from deviating or shaking, ensuring the accuracy of the brushing path and improving the cleaning quality.
[0047] The longitudinal cross-sectional shape of the guide groove on the top surface of the working plate 1 is I-shaped, and the shape of the guide block 56 is I-shaped to match the shape of the guide groove on the top surface of the working plate 1.
[0048] The I-shaped guide groove on the top surface of the working plate 1 and the matching I-shaped guide block 56 make the operation of the moving rod 55 more reliable. The special shape design enhances the connection strength, prevents the guide block 56 from falling out, effectively copes with long-term high-frequency use, and extends the service life of the device.
[0049] It should be added that the pump body 41, drive motor 54, electric cylinder 510, and cleaning motor 513 are all electrically connected to an external PLC via wires, and the pump body 41, drive motor 54, electric cylinder 510, and cleaning motor 513 are all electrically connected to an external power supply via wires, and the external PLC is also electrically connected to an external power supply via wires.
[0050] Finally, it should be noted that the components involved in this utility model, such as the gate body 2, pump body 41, drive motor 54, electric cylinder 510, and cleaning motor 513, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.
[0051] In this embodiment, during actual use, the piston rods of the two electric cylinders 510 are first extended to push the two U-shaped plates 59 to bring the brush rollers 512 close to the surface of the gate body 2 and adjust to a suitable cleaning distance. At the same time, the PLC starts the cleaning motor 513 to drive the brush rollers 512 to rotate at high speed.
[0052] Subsequently, the PLC starts the drive motor 54, which drives the bidirectional lead screw 53 to rotate, causing the two moving rods 55 to reciprocate linearly along the guide groove on the working plate 1, realizing the movement and cleaning of the brush roller 512 in the left and right directions of the gate. During this process, the PLC also controls the piston rods of the two electric cylinders 510 to perform periodic extension and retraction movements, driving the brush roller 512 to move in the front and back directions, so that the brush roller 512 rotates while performing a "Z" shaped trajectory cleaning in the plane, covering the surface of the gate in all directions.
[0053] During cleaning, the PLC starts the pump body 41, which delivers water from the external water supply device to the nozzle 43 through the water pipe 42. The nozzle 43 sprays water onto the gate disc, which, together with the brush roller 512, washes away dirt in time.
[0054] After the cleaning task is completed, the PLC controls the pump body 41 to stop water supply, the cleaning motor 513 and the drive motor 54 to stop rotating, and then controls the piston rods of the two electric cylinders 510 to retract, so that the brush roller 512 leaves the gate plate. The device returns to its initial state and waits for the next work instruction.
