Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine production, and particularly relates to a hoisting device for coal mine electromechanical transportation. Background Technique

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and open-pit coal mines. A coal mine is a reasonable space excavated by humans when excavating coal-rich geological strata, usually including roadways, shafts, and working faces, etc.

[0003] When a coal mine is being mined, it is usually necessary to move electromechanical equipment to facilitate the mining of coal in other areas. When moving electromechanical equipment, hoisting equipment is usually required. However, the counterweight of existing hoisting equipment is usually fixed at one end of the boom and does not have an adjustment function. When hoisting electromechanical equipment of different weights, it will cause the center of gravity to be unstable and prone to collapse. This will not only cause damage to the equipment, but also pose a certain safety hazard to the surrounding workers. Therefore, we have proposed a hoisting device for coal mine electromechanical transportation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting device for coal mine electromechanical transportation. By setting an adjustment component, specifically, starting the second hydraulic cylinder to drive the placement box to move forward or backward, the placement box will drive the slider to slide on the slide rail, which can make the movement of the placement box more stable and smooth. Through the movement of the placement box, the distance of the counterweight can be controlled, so as to adjust according to equipment of different weights, making the hoisting device more stable, avoiding the situation of unstable center of gravity, preventing collapse, and protecting the equipment and workers from being injured. It solves the problem that the counterweight of existing hoisting equipment is usually fixed at one end of the boom and does not have an adjustment function. When hoisting electromechanical equipment of different weights, it will cause the center of gravity to be unstable and prone to collapse.

The back of the crane arm 12 is fixedly connected to the front of the fixed frame 131. The front output end of the second hydraulic cylinder 132 is fixedly connected to the back of the placing box 133.

[0029] A telescopic arm 121 is slidably connected inside the lifting arm 12. The front of the telescopic arm 121 penetrates through the lifting arm 12 and extends to the outside. A lifting device 122 is fixedly connected to the front of the telescopic arm 121. A fixed block 123 is fixedly connected to the inner wall of the lifting arm 12. By setting the telescopic arm 121, specifically, starting the motor 124 drives the threaded rod 125 to rotate. Therefore, the telescopic arm 121 will move forward or backward on the threaded rod 125 through the fixed threaded block 211, thereby adjusting the distance of the lifting device 122. The telescoping of the telescopic arm 121 facilitates better lifting and can be used for hoisting in various areas.

[0030] A motor 124 is fixedly connected to the back of the fixed block 123. A threaded rod 125 is rotatably connected inside the fixed block 123. A limit block 126 is rotatably connected to the front of the threaded rod 125. The top and bottom of the limit block 126 penetrate through the telescopic arm 121 and extend to the outside.

[0033] A specific application of this embodiment is:

[0034] During use, move the vehicle body 1 to the position where hoisting is required. Then, start the first hydraulic cylinder 111 to drive the connecting block 112 to move upward or downward, adjusting the height of the boom 12, which can be applied to various mine shafts. Since the bottom of the boom 12 is rotatably connected to the limit shaft 113 and the connecting block 112 through a rotating shaft 127, the angle of the boom 12 can be adjusted by pushing, facilitating better hoisting. Then, start the motor 124 to drive the threaded rod 125 to rotate. Since the fixed threaded block 211 is threadedly connected to the threaded rod 125, the telescopic arm 121 will move forward or backward on the threaded rod 125 through the fixed threaded block 211, thereby adjusting the distance of the hoisting device 122.

The telescoping of the telescopic arm 121 facilitates better hoisting. After the movement is completed, hoist the electromechanical equipment through the hoisting device 122. By starting the second hydraulic cylinder 132 to drive the placement box 133 to move forward or backward, the placement box 133 will drive the slider 135 to slide on the slide rail 136, enabling the placement box 133 to move more stably and smoothly. By moving the placement box 133, the distance of the counterweight can be controlled, so as to adjust according to equipment of different weights, making the hoisting equipment more stable, avoiding the situation of unstable center of gravity and preventing collapse, protecting the equipment and the staff from being injured. At the same time, multiple or a small number of counterweight blocks 134 can be placed in the placement box 133 according to different needs to adjust the counterweight again.
