Electric ring chain elevator

Abstract

The invention discloses an electric ring chain elevator and belongs to the technical field of the design of hoisting devices. The electric ring chain elevator comprises an upper lifting hook, an upper spring buckle, a chain wheel box, a chain, a fixing base, a lower lifting hook, a lower spring buckle, a controller and a control cabinet. The upper lifting hook is fixed to the top of the chain wheel box. The whole device can be hung on a workshop truss through the upper lifting hook. A chain wheel is installed in the chain wheel box. A chain wheel shaft is supported on a box body of the chain wheel box. The chain winds across the chain wheel in an inner cavity of the chain wheel box. The lower lifting hook is fixed to the bottom of the chain. A weight is hooked by the lower lifting hook when the weight is hoisted, and the weight can be lifted to the required position by pulling the chain. The control cabinet is fixed to the front portion of the chain wheel box. According to the electric ring chain elevator, operation is convenient, the cost is low, and the safety is good; the weight is unlikely to fall in the conveying process; the upper lifting hook and the lower lifting hook are high in strength, the bearing capacity is high, the service life is long, braking is rapid, and positioning is accurate.

Description

technical field [0001] The invention relates to the technical field of hoisting device design, in particular to an electric chain hoist. Background technique [0002] In the mechanical industry and daily life, we often need to carry out heavy objects in a certain range. In some cases, because the weight of the heavy objects is too large, the traditional manual method will cause the labor intensity of the workers and the handling efficiency is low. Previously Due to defects in the structural design of the heavy object lifting device used, there is no special braking device, which leads to the need to manually pull the chain to prevent the sprocket from reversing during the transportation of the heavy object. The labor intensity of the workers is high, the operation is troublesome, and the efficiency Low, and sometimes it may even drop suddenly during the transportation of heavy objects, causing major safety problems. Therefore, a design is designed that is easy to operate, lo...
