Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of mine hoists, and in particular to a self-adaptive counterweight balancing adjustment device for a shaft hoist. Background Art
[0002] A mine hoist is the primary transportation equipment connecting the underground and surface areas in mining operations. Installed on the surface, it uses wire ropes to propel a container along a shaft or ramp. It is used to hoist coal, ore, and gangue in vertical and inclined shafts, as well as to lower personnel, materials, tools, and equipment. A mine hoist, sometimes called a mine elevator, is a specialized form of elevator that can also be considered a simple lift. Mine hoists are crucial tools for transporting people and goods in mines.
[0003] At present, when a mine hoist is in use, in order to reduce the work of the traction machine and improve energy conservation, the counterweight balance is adjusted to ensure that the hoisting structure and the counterweight block reach a certain state of balance. That is, the existing technology uses the method of adjusting different numbers of counterweight blocks to change the counterweight mass to achieve a certain balance. However, since the mass of a single counterweight block is certain, while the load of the hoisting structure is different, changing the counterweight by changing the number of counterweight blocks will produce a relative error with the load of the hoisting structure, which will still affect the counterweight balance of the entire hoist. In order to ensure the counterweight balance of the mine hoist, a certain shaft hoist counterweight balance adjustment device on the market uses the method of increasing and decreasing the amount of liquid in the counterweight block to adjust the counterweight balance, which has a certain market share.
[0004] After searching, the invention patent with publication number CN114249216A discloses an energy-saving elevator with automatic counterweight adjustment, including an elevator shaft, an elevator car and a traction machine arranged in the elevator shaft. The traction machine is arranged at the top of the elevator shaft. The traction machine is equipped with a traction rope, one end of which is connected to the top of the elevator car, and the other end of which is connected to the elevator counterweight. The elevator counterweight includes a counterweight housing, a cavity is provided in the counterweight housing, and the cavity is connected to an automatic liquid filling and extraction system. The elevator also includes a controller and a weighing sensor. The weighing sensor feeds the total mass data signal of the elevator car back to the controller, and the controller then controls the hydraulic pump to input or extract liquid from the counterweight according to the balance principle, so that the mass of the counterweight is consistent with the mass of the car, thereby reducing the power consumption of the traction machine and achieving energy saving.
[0005] Based on the above search and combined with the existing technology, it was found that the existing technology adjusts the counterweight balance by increasing and decreasing the amount of liquid. Although it can solve the counterweight balance problem of the entire hoist, as the counterweight block rises and falls, the stability of the liquid inside cannot be controlled, and the liquid is prone to shaking and causing the counterweight block to vibrate, thereby affecting the balance of the entire hoist. Therefore, an adaptive hoist counterweight balance adjustment device is proposed to improve the above problem. Summary of the Invention

[0060] Working principle: When in use, a pulley-type traction mechanism is formed by a fixed pulley 5, a plurality of first traction ropes 13, a movable pulley 15, a traction machine 11 and a plurality of second traction ropes 14. The traction machine 11 in the traction mechanism drives the plurality of first traction ropes 13 and the second traction ropes 14 to move, so as to facilitate the lifting and lowering operations of the material lifting assembly 3 and the counterweight. When the staff below the mine places the material on the material lifting rack 301, the first pressure sensor 305 is used to detect the weight on the material lifting rack 301, and the weight signal is transmitted to the single-chip controller to control the hydraulic cylinder 19, the first control valve 27 and the upper The first pump body 25 works successively, and can connect the female pipe connector 22 with the male pipe connector 23 under the action of the hydraulic cylinder 19, and open the first control valve 27, and cooperate with the first pump body 25 to pump the liquid in the upper water tank 9 into the counterweight water tank 10. When the weight detected by the second pressure sensor 29 is equal to the weight detected by the first pressure sensor 305, the single-chip controller controls the first pump body 25 and the first control valve 27 to be closed and the hydraulic cylinder 19 to be reset to keep the counterweight balanced; when the material lifting frame 301 is moved to the highest position by the traction mechanism, the counterweight water tank 10 will move to the lowest position. At this time, the work above the mine is The worker takes the material away and continues to detect the weight on the material lifting frame 301 through the first pressure sensor 305, and transmits the weight signal to the single-chip controller to control the hydraulic cylinder 19, the first control valve 27 and the first pump body 25 to work in sequence. Under the action of the hydraulic cylinder 19, the female pipe connector 22 and the male pipe connector 23 can be docked, and the first control valve 27 is opened, and the first pump body 25 below is used to pump the liquid in the counterweight water tank 10 back into the lower water tank 7. When the weight detected by the second pressure sensor 29 is equal to that detected by the first pressure sensor 305, the single-chip controller controls the first pump body 25 and the first control valve 27 to pump the liquid in the counterweight water tank 10 back into the lower water tank 7. The valve 27 is closed and the hydraulic cylinder 19 is controlled to reset to maintain the counterweight balance, thereby realizing liquid compensation counterweight. The amount of liquid in the counterweight water tank 10 can be increased or decreased to adjust the counterweight balance of the mine hoist. Moreover, when the liquid in the upper water tank 9 decreases and the liquid in the lower water tank 7 increases, the single-chip microcomputer controller controls the second control valve 34 to open and also controls the second pump body 33 to rotate forward or reverse, so that the liquid in the upper water tank 9 and the lower water tank 7 circulates. The third pressure sensor 35 cooperates to detect the weight of the liquid in the upper water tank 9 and the lower water tank 7, thereby maintaining the liquid content in the upper water tank 9 and the lower water tank 7 at the same level.Furthermore, when the hydraulic cylinder 19 extends, it drives the movable plate 20 and the rack 1703 within the water-stabilizing assembly 17 to move synchronously. The meshing action of the rack 1703 and the gear 1701 drives the mounting shaft 1702 and the partition plate 1705 to rotate, facilitating faster circulation of liquid within the counterweight tank 10. When the hydraulic cylinder 19 contracts, it also drives the partition plate 1705 to reset, allowing the partition plate 1705 to remain vertical within the water storage chamber, thereby dividing the interior of the water storage chamber into multiple water storage areas and blocking the lateral movement of the liquid within the counterweight tank 10. This allows the stability of the liquid to be controlled during the raising and lowering of the counterweight 12, preventing the liquid from sloshing and causing vibrations in the counterweight 12.
[0061] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
