Problems solved by technology

For spreaders or cranes, no matter whether electric or hydraulic control is used, once a sudden power failure occurs, it will bring unsafe factors, and hydraulic control is used, and the hydraulic control circuit is more complicated. The cost of use is high, and maintenance is inconvenient. In use, due to changes in temperature, concentration and purity of hydraulic oil, the pressure will fluctuate greatly, and it is not stable enough.

Abstract

The invention discloses a sorting hanger lifting device. The sorting hanger lifting device comprises a walking rack and a clamping rack. A top surface of the walking rack is fixed with a lifting cylinder and a lifting shaft. The lifting cylinder drives the lifting shaft to rotate through a gear drive mechanism. A reel is fixed on the lifting shaft. Upper fixed pulleys are fixed on a top surface of a support and are located respectively at two sides of the reel. Two to six movable pulleys are fixed on a top surface of the clamping rack. A certain number of lower fixed pulleys are fixed on a bottom surface of the walking rack, wherein the number of the lower fixed pulleys is one less than that of the movable pulleys. After rounding the upper fixed pulleys located at one side, a closed steel wire rope rounds orderly the movable pulleys, the lower fixed pulleys and the upper fixed pulleys located at the other side. An excess part of the closed steel wire rope is stored up through the reel. The sorting hanger lifting device has safe and reliable performances, can carry out stable lifting processes, and can save energy.

Description

technical field [0001] The invention relates to a hoisting device for a spreader. Background technique [0002] In industrial production, it is often necessary to use a spreader to move the finished or semi-finished product from one place to another. For example, in the production process of aerated concrete, it is necessary to lift the finished aerated concrete out of the autoclave to the finished product warehouse with a spreader , so the spreader is the main supporting equipment in the production of aerated concrete. The Chinese patent No. 200420028850.4 utility model patent specification discloses a finished product crane which belongs to special equipment for aerated concrete. There are two spreader arms running between the two vertical rails, and a clamp beam is fixed between the two spreader arms, and a row of opposing clamps are evenly distributed and fixed on the clamp beam. The crane uses the chain wheel group to pull the chain through the hydraulic cylinder to r...
