Lifting machine telescopic stabilizing mechanism

Abstract

The invention discloses a lifting machine telescopic stabilizing mechanism. The mechanism comprises a double-rail trolley frame, the bottom of the double-rail trolley frame is connected with a fixed frame, one side of the double-rail trolley frame is connected with a lifting driving device, a belt fixing end is arranged at the lower end of the double-rail trolley frame, a belt is connected below the belt fixing end, a multi-stage movable frame is arranged at the lower end of the fixed frame in a sliding mode, a plurality of sets of guide pulley blocks are arranged between the fixed frame and the movable frame at the uppermost end, the guide pulley blocks are also arranged between any two adjacent movable frames, a lifting sliding wheel is fixedly connected in the movable framework at the bottommost end, the lifting driving device drives the movable frame to slide up and down through the belt and the lifting sliding wheel. According to the lifting machine telescopic stabilizing mechanism, the problem that the workpiece shakes in the lifting process is effectively solved, the positioning precision of the workpiece is improved, the fault rate is reduced, and the operation of the equipment is more stable.

Description

【Technical field】 [0001] The invention relates to the technical field of intelligent conveying systems, in particular to a telescopic stabilization mechanism of a hoist. 【Background technique】 [0002] The hoist is a new type of suspension conveying equipment for large or ultra-wide workpieces in the automobile industry. It is mainly used for conveying workpieces in the large-scale production lines of the automobile manufacturing industry. Synchronous use to avoid shaking when the hoist lifts the workpiece and ensure accurate positioning of the workpiece. Existing hoist telescopic stabilization systems mainly include: electric hoist hoisting mechanism with scissors and forks, four-belt stabilizing hoisting mechanism and four-chain stabilizing hoisting mechanism. The above-mentioned first lifting mechanism uses scissors and forks to enhance its running stability and reduce the shaking of the workpiece during lifting. However, its bearing capacity is small and its guiding sta...

AI Technical Summary

Problems solved by technology

The above-mentioned first lifting mechanism uses scissors and forks to enhance its running stability and reduce the shaking of the workpiece during lifting. However, its bearing capacity is small and its guiding stability needs to be improved when the lifting height is high. ; The above-mentioned second and third lifting mechanisms respectively use belts and chains to form a circulating lifting mechanism, which has a complex structure, poor guiding stability, and unstable system operation, which leads to low positioning accuracy of the workpiece, reduces work efficiency, and is inconvenient to use
