An ore hoist

Abstract

This invention provides an ore hoist, comprising a main carrier plate, a secondary carrier plate, a first brush plate, a second brush plate, a connecting rod, a carrier belt, a drive roller, and at least one driven roller. The carrier belt is wound around the outer circumferential surfaces of the drive roller and the driven roller. The main carrier plate is fixedly connected to the carrier belt, and the secondary carrier plate is fitted inside the main carrier plate. The first brush plate is in frictional engagement with the outer surface of the main carrier plate and is also fixedly connected to the secondary carrier plate. The second brush plate is in frictional engagement with the surface of the carrier belt. One end of the connecting rod is hinged to the first brush plate, and the other end of the connecting rod is hinged to the second brush plate. Using the technical solution of this invention, during operation of the ore hoist, the secondary carrier plate frequently extends beyond or retracts within the main carrier plate, simultaneously driving the first brush plate to slide along the outer surface of the main carrier plate and the second brush plate to slide along the outer surface of the carrier belt. This cleans or sweeps away slag adhering to the outer surfaces of the main carrier plate and the carrier belt, shortening the downtime of the ore hoist and improving its transportation efficiency.

Description

Technical Field

[0001] This invention belongs to the field of hoisting technology, and in particular to an ore hoisting machine. Background Technology

[0002] In mining engineering, the mined ore is transported in two main ways. One way is to use transport trolleys to travel along pre-laid tracks to transport the ore from the underground mine to the outside. The other way is to use belt conveyors or hoists to transport the ore. The structure of a belt conveyor or hoist generally includes a transport belt, which is used to load ore. However, after the belt conveyor or hoist has been running continuously for a long time, slag easily adheres to the surface of the belt. This slag is difficult to remove and increases the operating load of the equipment, affecting the transport efficiency. In addition, residual slag can seep into the internal structure of the equipment, causing wear and tear on corresponding internal parts and even damaging the transport equipment. In order to remove, clean, or repair the equipment, it is necessary to stop the equipment first and then clean the slag adhering to the belt surface, which seriously affects the efficiency of the equipment in carrying ore. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an ore hoist.

[0004] The present invention is achieved through the following technical solutions.

[0005] This invention provides an ore hoist, comprising a main carrier plate, a secondary carrier plate, a first brush plate, a second brush plate, a connecting rod, a carrier belt, a drive roller, and at least one driven roller. The carrier belt is wound around the outer circumferential surfaces of the drive roller and the driven roller. The main carrier plate is fixedly connected to the carrier belt. The secondary carrier plate is fitted inside the main carrier plate. The first brush plate is in frictional engagement with the outer surface of the main carrier plate and is also fixedly connected to the secondary carrier plate. The second brush plate is in frictional engagement with the surface of the carrier belt. One end of the connecting rod is hinged to the first brush plate, and the other end of the connecting rod is hinged to the second brush plate.

[0006] The ore hoist also includes a support spring, and a limiting plate is provided inside the main carrier plate. The support spring is connected between the auxiliary carrier plate and the limiting plate.

[0007] The sub-carrier plate is also fixedly connected to the guide rod, which passes through the support spring.

[0008] The active roller is also housed in the base. The gap between the carrier belt and the inner wall of the base forms a feeding channel. The surface of the base is also provided with an injection channel and an overflow return channel. The injection channel is connected to the feeding channel, and the overflow return channel is connected to the injection channel.

[0009] The ore hoist also includes a tension spring, a wire rope, and a flywheel. One end of the tension spring is fixedly connected to the inner wall of the overflow return channel, and the other end of the tension spring is fixedly connected to one end of the wire rope. The other end of the wire rope is hinged to the flywheel. The flywheel is coaxially fixedly connected to the drive roller, and the flywheel is arranged outside the base.

[0010] The base is also fixed to a conduit through which the steel wire rope passes.

[0011] The ore hoist also includes a drive motor, which is mounted on the surface of the base, and the output shaft of the drive motor is coaxially and fixedly connected to the drive roller.

[0012] The left and right ends of the driving roller and the driven roller are respectively fixedly connected to the baffle.

[0013] The ore hoist also includes multiple pairs of support legs, with the upper ends of the support legs hinged to the baffle and the lower ends of the support legs supported on the ground.

[0014] The outer circumferential surfaces of the driving roller and the driven roller are provided with gear teeth, and the inner surface of the carrier belt is provided with corresponding belt grooves, with the gear teeth fitting into the corresponding belt grooves.

[0015] The beneficial effects of this invention are as follows: When the ore hoist is running, when the auxiliary carrier plate moves to a position close to the drive roller, it is retracted into the main carrier plate under the squeezing action of the base. When the auxiliary carrier plate moves to a position away from the drive roller, it extends beyond the main carrier plate, expanding the load area of ​​the carrier plate and thus increasing the ore conveying capacity. During the process of the auxiliary carrier plate extending beyond or retracting into the main carrier plate, the auxiliary carrier plate simultaneously drives the first brush plate to slide along the outer surface of the main carrier plate and the second brush plate to slide along the outer surface of the carrier belt, thereby cleaning or sweeping the slag attached to the outer surface of the main carrier plate and the outer surface of the carrier belt. This achieves the purpose of timely and automatic cleaning or sweeping of slag during the operation of the ore hoist, avoiding the long-term accumulation of slag and increasing the operating load of the ore hoist, ensuring the safe and stable operation of the ore hoist, and thus shortening the downtime for maintenance and slag cleaning, and improving the transportation efficiency of the ore hoist.

Detailed Implementation

[0025] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0026] like Figures 1 to 8 As shown, the present invention provides an ore hoist, including a main carrier plate 1, a secondary carrier plate 2, a first brush plate 3, a second brush plate 4, a connecting rod 5, a carrier belt 6, a drive roller 7, and at least one driven roller 8. The carrier belt 6 is wound around the outer circumferential surface of the drive roller 7 and the driven roller 8. The main carrier plate 1 is fixedly connected to the carrier belt 6. The secondary carrier plate 2 is fitted inside the main carrier plate 1. The first brush plate 3 is in frictional engagement with the outer surface of the main carrier plate 1, and the first brush plate 3 is also fixedly connected to the secondary carrier plate 2. The second brush plate 4 is in frictional engagement with the surface of the carrier belt 6. One end of the connecting rod 5 is hinged to the first brush plate 3, and the other end of the connecting rod 5 is hinged to the second brush plate 4.

[0027] By employing the technical solution of this invention, when the ore hoist is running, when the auxiliary carrier plate moves to a position close to the drive roller, it is retracted into the main carrier plate under the squeezing action of the base. When the auxiliary carrier plate moves to a position away from the drive roller, it extends beyond the main carrier plate, expanding the load area of ​​the carrier plate and thus increasing the ore conveying capacity. During the process of the auxiliary carrier plate extending beyond or retracting into the main carrier plate, the auxiliary carrier plate simultaneously drives the first brush plate to slide along the outer surface of the main carrier plate and the second brush plate to slide along the outer surface of the carrier belt, thereby cleaning or sweeping the slag attached to the outer surface of the main carrier plate and the outer surface of the carrier belt. This achieves the purpose of timely and automatic cleaning or sweeping of slag during the operation of the ore hoist, avoiding long-term accumulation of slag and increasing the operating load of the ore hoist, ensuring the safe and stable operation of the ore hoist, thereby shortening the downtime for maintenance and slag cleaning, and improving the transportation efficiency of the ore hoist.

[0028] Specifically, the ore hoist also includes a support spring 9, and a limiting plate 10 is provided inside the main carrier plate 1. The support spring 9 is connected between the auxiliary carrier plate 2 and the limiting plate 10. The auxiliary carrier plate 2 is also fixedly connected to a guide rod 11, which passes through the support spring 9.

[0029] In addition, the drive roller 7 is also housed within the base 12. The gap between the carrier belt 6 and the inner wall of the base 12 forms a feeding channel 13. The surface of the base 12 is also provided with an injection channel 14 and an overflow return channel 15. The injection channel 14 is connected to the feeding channel 13, and the overflow return channel 15 is connected to the injection channel 14. Using the technical solution of this invention, when a large amount of ore is transported to the upper end by the ore elevator, some ore will overflow along the edge of the main or auxiliary carrier plate. The overflowing ore can roll down along the length of the carrier belt and eventually return to the surface of the main or auxiliary carrier plate for re-transportation via the overflow return channel, thereby reducing ore falling and helping to reduce ore waste.

[0030] In addition, the ore hoist also includes a tension spring 16, a wire rope 17, and a flywheel 18. One end of the tension spring 16 is fixedly connected to the inner wall of the overflow return channel 15, and the other end of the tension spring 16 is fixedly connected to one end of the wire rope 17. The other end of the wire rope 17 is hinged to the flywheel 18, which is coaxially fixedly connected to the drive roller 7 and is located outside the base 12. The base 12 is also fixedly connected to a guide tube 19 through which the wire rope 17 passes. Using the technical solution of this invention, as the drive roller rotates, the flywheel 18 rotates accordingly, causing the tension spring 16 to repeatedly stretch or contract under the pulling action of the wire rope 17. This repeatedly agitates the ore collected in the overflow return channel 15, causing the surface ore to block the overflow return channel 15, thus ensuring the safe and stable operation of the ore hoist.

[0031] Specifically, the ore hoist also includes a drive motor 20, which is mounted on the surface of the base 12, and the output shaft of the drive motor 20 is coaxially and fixedly connected to the drive roller 7. The drive roller 7 and the driven roller 8 are also fixedly connected to baffles 21 at their left and right ends, respectively. The ore hoist also includes multiple pairs of support legs 22, the upper ends of which are hinged to the baffles 21, and the lower ends of which are supported on the ground. The support legs 22 are telescopic.

[0032] In addition, the outer circumferential surfaces of the driving roller 7 and the driven roller 8 are provided with gear teeth 23, and the inner surface of the carrier belt 6 is provided with corresponding grooves 24, with the gear teeth 23 fitting into the corresponding grooves 24. This prevents the carrier belt 6 from slipping relative to the outer circumferential surfaces of the driving roller 7 and the driven roller 8, ensuring the reliable operation of the ore hoist.
