Description
Technical Field
The utility model relates to a lifting beam of underground coal mine heavy equipment.
Background
Heavy equipment such as a forced-ventilated pump (about 10 tons) and the like in underground coal mines needs to be lifted periodically to clean floating coal in the chamber, so that normal performance is ensured. The heavy equipment is lifted by constructing a special anchor rope for lifting in a chamber or a tunnel roof, fixing a 40-chain (18X 64 mm) through a lock, and hanging one or more guide chains on the chain. According to the physics and the atress characteristic of anchor rope, after the repetitious usage, the anchor rope that lifts by crane can gradually cause the anchor rope steel strand wires fracture owing to receive tool to lock shearing force effect, leads to lifting by crane the anchor rope to scrap, and even the anchor rope fracture causes heavy equipment to fall, causes personnel injury or equipment to damage. Therefore, in the hoisting operation process of underground heavy equipment of a coal mine, the production of a safe and reliable hoisting device is a field requirement and a requirement for safety development.

patent application number: CN202121312513.8 discloses a beam of a lifting device for coal mine electromechanical transportation, comprising a base and a hook, wherein the hook is arranged at the top of the right side of the base, the top of the base is fixedly connected with a mounting box, the front side of the bottom of the inner wall of the mounting box is fixedly connected with a supporting plate, and the top of the supporting plate is fixedly connected with a water pump. According to the utility model, the electric hoist is started to drive the hook to hoist the coal mine, the water pump is started to enable the input end to suck water from the water tank through the water suction pipe, the water is enabled to reach the inside of the telescopic hose through the water outlet pipe and the through hole, and finally the water is sprayed out through the telescopic hose to reach the turntable, so that the problems that the environment quality is poor on site, dust is scattered, the sight of workers is influenced, accidents can be caused, and the physical health of people is influenced in the hoisting process of the coal mine are solved, and the automatic sprinkling advantage is realized.
(2) Patent application number: CN202210923328.5 discloses a lifting beam, comprising a brake assembly, wherein the brake assembly comprises a brake bearing frame for hanging on a hanging rail, a first brake plate and a second brake plate hinged on two opposite sides of the brake bearing frame respectively, and a brake driving member hinged between the first brake plate and the second brake plate, wherein one ends of the first brake plate and the second brake plate far away from the brake driving member are correspondingly hinged with a first brake wheel and a second brake wheel respectively. When the distance between one ends of the first brake plate and the second brake plate is increased under the drive of the brake driving piece, the distance between one ends of the first brake plate and the second brake plate, which are far away from the brake driving piece, is reduced according to the lever principle, and the first brake wheel and the second brake wheel synchronously slide along the brake bearing frame and are mutually closed until the suspension rail is clamped under the drive of the two brake plates, so that braking is realized, the risks of safety accidents such as out of control, sliding and the like are reduced, and the safety is improved.
Disclosure of Invention
The utility model aims to manufacture a lifting beam of underground coal mine heavy equipment, which has the advantages of simple structure, high use safety coefficient and strong environmental adaptability.
The technical scheme adopted by the utility model is that the lifting beam of the underground heavy equipment of the coal mine consists of a straight beam and a lifting chain, wherein the straight beam is formed by processing 11# mining I-steel, drilling holes with the diameter of 22mm are respectively and vertically arranged at intervals of 400mm at the two ends of the beam, steel pipes with the diameter of 20mm are welded in the drilling holes, anchor cables penetrate through the steel pipes, and locks are arranged at the lower ends of the anchor cables; the middle part of the straight beam is transversely penetrated and provided with a reinforced round steel with the diameter of 20mm along the waist direction of the mining I-shaped steel, the two sides of the reinforced round steel are respectively and fixedly provided with a chain ring, and the chain rings are connected with a lifting chain in a hanging way.
When the device is used, the jumbolter is used for constructing 2 anchor cables with the diameter of 17.8mm on a top plate of a roadway on the upper part of heavy equipment to be lifted, the distance is 400mm, then the 2 anchor cables respectively penetrate through the lifting beam reinforcing steel pipe, the 18mm lockset is used for locking and fixing, and finally the device is tensioned according to the process, and the tensioning force reaches 200kN to be qualified. And hanging a lifting appliance on a lifting chain of the lifting beam by using a chain connecting ring, and then operating the lifting appliance to lift the heavy object. The lifting appliance with the capability reaching the standard is selected according to the actual weight of heavy equipment, and a plurality of lifting beams can be installed for combined use.
