Description
Technical Field
[0001] The 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] Mine hoist refers to the main transportation equipment that connects the underground and the ground in mining projects. Mine hoist is a lifting machine installed on the ground, which drives the lifting container along the shaft or ramp with the help of wire rope. It is used to lift coal, ore, gangue in vertical and inclined shafts, as well as to lift and lower personnel, materials, tools and equipment. Mine hoist is sometimes also called mine elevator. It is a special form of elevator and can also be regarded as a simple elevator. In the project of transporting people and objects in mines, mine hoist is a very important transportation tool.
[0003] At present, when the mine hoist is in use, in order to make the traction machine do less work and save energy, the counterweight balance is adjusted to ensure that the hoisting structure and the counterweight block reach a certain balance state, 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, and 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, and 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.

The weighing sensor feeds back the total mass data signal of the elevator car to the controller, and the controller controls the hydraulic pump to input or extract the 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 to achieve energy saving.
[0005] Based on the above search and in combination with the prior art, it is found that the prior art adjusts the counterweight balance by increasing or decreasing the amount of liquid. Although this 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. The liquid is prone to shaking and causing the counterweight block to vibrate, thereby affecting the balance of the entire hoist.

[0060] Working principle: When in use, a pulley block 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 operation of the material lifting assembly 3 and the counterweight. When the staff below the mine places the material on the material lifting frame 301, the first pressure sensor 305 is used to detect the weight on the material lifting frame 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 dock 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 first pump body 25 and the first control valve 27 are closed and the hydraulic cylinder 19 is reset through the single-chip controller to keep the counterweight balanced; when the material lifting frame 301 is moved to the highest position through the traction mechanism, the counterweight water tank 10 will move to the lowest position. At this time, the upper part of the mine is operated. The worker takes away the material, 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 can be docked with the male pipe connector 23, and the first control valve 27 can be opened to cooperate with the first pump body 25 below 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 be reset to keep the counterweight balanced, thereby realizing liquid compensation counterweight. The amount of liquid can be increased or decreased in the counterweight water tank 10 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 second control valve 34 is controlled to open by the single-chip microcomputer controller, and the second pump body 33 is also controlled to rotate forward or reverse, so that the liquid in the upper water tank 9 and the lower water tank 7 presents a circulating flow, and cooperates with the third pressure sensor 35 to detect the weight of the liquid in the upper water tank 9 and the lower water tank 7, so as to keep the liquid content in the upper water tank 9 and the lower water tank 7 equal.Moreover, when the hydraulic cylinder 19 is extended, the movable plate 20 and the rack 1703 in the water-stabilizing assembly 17 can be driven to move synchronously, and the meshing action of the rack 1703 and the gear 1701 can drive the mounting shaft 1702 and the partition plate 1705 to rotate, so that the liquid can flow more quickly in the counterweight water tank 10. When the hydraulic cylinder 19 is contracted, the partition plate 1705 can be driven to reset, so that the partition plate 1705 remains vertical in the water storage cavity, thereby dividing the interior of the water storage cavity into multiple water storage areas, blocking the lateral movement of the liquid in the counterweight water tank 10, so that the stability of the liquid can be controlled during the lifting process of the counterweight block 12, avoiding the problem of the liquid shaking and driving the counterweight block 12 to vibrate. ;
