A kind of monorail crane used in coal mine development

Abstract

The invention relates to the technical field of coal mine equipment, and discloses a monorail crane used in coal mine development. There are hydraulic chambers on both sides inside the carrier body. The top of the hydraulic chamber is horizontally movable and socketed with a hydraulic rod, and the outer end of the hydraulic rod is fixedly connected. There is a brake block and the brake block is located at the center of the traveling wheel. An electromagnet is fixedly installed in the center of the carrier body. A movable chamber is located inside the carrier body between the electromagnet and the hydraulic chamber. The movable chamber is close to the hydraulic pressure chamber. One side of the chamber is movably socketed with a top block, and the end of the top block close to the electromagnet is fixedly connected with a support spring, and the side of the top block close to the hydraulic chamber is fixedly connected with a sealing plug extending into the hydraulic chamber, and the inside of the top block is fixed. Bar magnets are installed, and by adopting hydraulic drive and cooperating with the braking effect of the brake block, the wear of the traveling wheel can be reduced and the braking effect is better. At the same time, the structural design of the braking wheel is used to further improve the braking effect and ensure safety.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a monorail crane used for coal mine development. Background technique [0002] During coal mining, with the change of mining depth, it is necessary to lengthen the cable to the required length. The traditional manual cable pulling is not only inefficient, but also easy to put out badly, which is not conducive to the mining of coal mines. Therefore, people have developed a monorail crane. , using a monorail with a driving and carrying device hanging on it, and using sliding on the monorail for transportation, not only saving manpower, but also the cable will not touch the inner wall of the mine in the air, but the existing cable monorail crane still has some problems : [0003] 1.

Problems solved by technology

[0002] During coal mine mining, as the depth of mining changes, it is necessary to lengthen the cable to the required length. The traditional method of manually pulling the cable is not only inefficient but also easy to place badly, which is not conducive to coal mining. Therefore, people have developed a monorail crane. , use a monorail to hang the driving and carrying device on it, use the sliding on the monorail for transportation, not only save manpower, but also the cable will not touch the inner wall of the mine in the air, but there are still some problems in the existing cable monorail crane :

[0003] 1. The existing monorail crane uses the brake oil cylinder to provide the braking force and transmits the force through the rotation of the brake arm to drive the traveling wheel to clamp the track to achieve braking. When the rotating arm is used to realize the force transmission and rotation On the one hand, it will cause the height after rotation to be inconsistent with the previous one, and it will give a biased force to the brake cylinder or brake wheel. This force will cause poor braking effect, and a sudden power failure during braking will also cause braking. The reset of the moving oil cylinder makes the monorail crane in the empty state, so that it will move and cause dangerous accidents;

[0004] 2. Since the bearing device is directly suspended on the track, there will be left and right offset shaking during the traveling process. When the shaking is large, the side of the walking wheel will rub against the track, which will cause loss of the walking wheel and is also prone to occurrence Accidents, and also reduce the speed of transportation. When the road wheel is braking, when the brake cylinder pushes the brake arm to clamp the road wheel in the middle, it will cause the rolling contact surface of the road wheel to rub against the guide rail, which will make the walking wheel Affected by friction loss, the wheel is no longer a cylindrical wheel, which is not conducive to the subsequent rolling conveyance
