Winch trolley of crane

Abstract

The invention discloses a winch trolley of a crane. The trolley comprises a support provided with a cross beam and longitudinal beams, two sliding supports, a rotating shaft, two arch sleeve frames and a driving mechanism; the bottoms of the sliding supports are arranged between the longitudinal beams in a sliding manner, the sliding supports are arranged in a manner of being parallel to the crossbeam, the rotating shaft is rotatably arranged on the tops of the sliding supports, and the length of the rotating shaft can be adjusted; the two arch sleeve frames are arranged on the two ends of the rotating shaft in a sleeving manner, steel ropes are wound on the sleeve frames, and the driving mechanism is arranged on one side of the rotating shaft and drives the rotating shaft to rotate. According to the winch trolley of the crane, one driving mechanism is adopted to drive the rotating shaft to rotate, the rotating shaft is provided with two spaced sleeve frames, simultaneous lifting of two lifting points can be achieved, lifting of a large workpiece is achieved, according to shapes and sizes of specific workpieces, the distance between the two lifting points can be adjusted, stability in the lifting process can be ensured, the workpiece can stably ascend and descend, and efficient lifting is achieved.

Description

technical field [0001] The invention relates to lifting equipment, in particular to a winch trolley of a crane. Background technique [0002] Hoist, a light and small lifting device that uses a reel to wind a wire rope or chain to lift or pull heavy objects, also known as a winch. The hoist can lift vertically, horizontally or obliquely to pull heavy objects. Mainly electric hoist, which can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large amount of winding rope, and convenient displacement. It is mainly used in construction, water conservancy, etc. Lifting or flat dragging of materials in engineering, forestry, mines, docks, etc.; in the prior art, it is often necessary to use a winch device to lift the workpiece. The hoisting device is a machine that uses a steel cable or a cable pulley block as a sling to connect with the workpiece, and the hoisting drum is wound ar...

AI Technical Summary

Problems solved by technology

Most of the existing hoisting devices are single-drive single-hoisting systems, acting on a single lifting point for the workpiece to be hoisted. For some large workpieces, two such hoisting devices need to be configured to meet the requirements, which undoubtedly increases the cost

However, most of the existing hoisting devices with multiple lifting points use two driving mechanisms to drive two steel ropes up and down, and the position is relatively fixed, which cannot be adjusted according to specific construction requirements, and two drives are required at the same time, which not only costs high, And it is difficult to control the synchronous lifting
