Description

Vertical heavy hammer tensioning device for belt conveyor
Technical Field
The utility model belongs to the technical field of mining auxiliary assembly, especially, relate to a perpendicular weight straining device for belt conveyor.
Background
The belt conveyor is a common material conveying device and is widely applied to the industrial departments of metallurgy, mining and the like. A belt conveyor is a device for continuously conveying materials by friction driving, and a tensioning device is needed to enable the conveying belt to have certain tensioning force in order to meet the requirements of friction driving of a transmission roller. In the medium and long distance conveyor, the vertical weight tensioning device is most applied. In the prior art, construction is mostly carried out in a hoisting mode, but frequent hoisting has great construction difficulty due to heavy weight of the heavy weight box, the efficiency is low, and subsequent overhaul is also inconvenient; meanwhile, if the conveyer belt is broken, the heavy hammer box can directly fall from the high altitude, so that personnel, equipment and the like below are seriously threatened, and safety accidents are easily caused.
Disclosure of Invention
For the weight straining device construction degree of difficulty among the solution prior art big, the inefficiency, overhaul inconvenient and the low technical problem of security, this practicality provides a perpendicular weight straining device for band conveyer.
In order to solve the technical problem, the utility model provides a perpendicular weight straining device for belt conveyor, include: hammering the bracket; the tensioning roller and the heavy hammer box are arranged in the heavy hammer tensioning bracket; the guard plate is arranged at the top of the heavy hammer tensioning bracket; the two heavy hammer tensioning guide rods are symmetrically arranged on two sides of the heavy hammer tensioning support, the top of each heavy hammer tensioning guide rod is fixedly connected with the trestle, and the bottom of each heavy hammer tensioning guide rod is fixedly connected with the ground; the crawling ladders are symmetrically arranged on the outer side edges of the two heavy hammer tensioning guide rods; the fixing buckle is arranged on the bottom surface of the trestle and is positioned between the two heavy hammer tensioning guide rods; the movable pulley block is arranged at the central part of the top of the guard plate; the first fixed pulley block and the second fixed pulley block are both arranged at the top of the trestle; the prop drawing winch is arranged on the ground; the third fixed pulley block is fixedly arranged on the ground and positioned between the prop pulling winch and the vertical pulling guide rod; one end of the steel wire rope is fixedly connected with the fixing buckle and sequentially bypasses the movable pulley block, the first fixed pulley block, the second fixed pulley block and the third fixed pulley block, and the other end of the steel wire rope is connected with the prop pulling winch.
The counterweight tensioning support is limited left and right by arranging the counterweight tensioning guide rod, so that the counterweight tensioning support can only move in the vertical direction; through setting up the cat ladder, make things convenient for the operation personnel to overhaul the device.
Compared with the hoisting construction technology in the prior art, the utility model starts the prop pulling winch when in installation or maintenance, and the heavy hammer box can be lifted to any position by the driving of the steel wire rope, the movable pulley block, the first fixed pulley block, the second fixed pulley block and the third fixed pulley block, thereby reducing the construction difficulty and improving the efficiency; the ladder stand is matched, so that the overhaul of the operating personnel is more convenient; when the conveyer belt broke, because the weight case passes through wire rope and links to each other with the prop pulling hoist, wire rope prevents the weight case with the braking force of 2 times prop pulling hoist and falls, avoids injuring below personnel and equipment, prevents the emergence of accident, has improved the security.
Preferably, the projection area of the guard plate on the horizontal plane is larger than that of the weight box on the horizontal plane. Through this setting, protect the weight case, prevent that weight case inner structure from suffering the sun and rain and drench.
The utility model discloses beneficial effect includes:
compared with the prior art, the utility model reduces the construction difficulty, improves the efficiency and is more convenient for the maintenance of the operators; meanwhile, when the conveying belt is accidentally broken, the heavy hammer box can be rapidly prevented from falling, personnel injury is avoided, and safety is improved.
