A coal mining cable monorail crane

Abstract

The invention relates to the technical field of coal mine mining equipment, and discloses a coal mine mining cable monorail crane, which includes a bearing device and a track. The top of the track is suspended on the top wall of the mine through a chain, and the outer sides of the two ends of the bearing device are movably socketed with telescopic shafts. , the middle parts on both sides of the carrying device are fixedly installed with cable hanging arms, the outer end of the telescopic shaft is movably installed with a brake arm, and the front and back of the top of the carrying device are symmetrically movably sleeved with supporting shafts. The top of the supporting shaft is fixed with a turntable, and the middle part of the outer ring of the turntable is provided with a circular groove, and a small roller is installed in the circular groove of the turntable evenly in a ring shape, and the outer side of the small roller is in contact with the bottom of the track. There is a hydraulic oil cavity inside the carrying device, and the telescopic shaft cooperates with the brake cylinder and the brake spring to achieve a good braking effect, and the turntable and small rollers also improve the stability.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a coal mining cable monorail crane. Background technique [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.

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. Since the mine is not a regular straight line, it has curvature and height changes. Therefore, when the monorail crane is used for sliding transportation, the pressure of the traveling wheels on both sides of the track on the track is different, and it is necessary to stop quickly when braking. , when the guide rail is in the inclined section of braking, the clamping force applied to the road wheels is constant, but because the gravity on both sides of the road wheels is different due to the inclination state, so the tightening is based on the friction force will make The tightening conditions on both sides are different, so that on the one hand, the friction of the walking wheels will be different, which will cause damage to the wheel body, and on the other hand, rollover or falling may also occur;

[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, while also reducing the speed of delivery;

[0005] 3. 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 friction between the rolling contact surface of the road wheel and the guide rail, so that the road wheel will no longer be affected by friction loss. It is a cylindrical wheel, which is not conducive to the subsequent rolling conveyance
