Problems solved by technology

[0003] Generally, the crane transports small heavy objects, and the machine changes from a moving state to a static state. During this process, the inertia of the rope will drive the heavy objects to tilt forward, resulting in swings, which is not conducive to the rapid placement of heavy objects, and the work efficiency is low. And when the rope swings violently, fragile items will be damaged by collision, resulting in unnecessary economic losses. Some cranes use the method of retracting and retracting the rope to avoid rope shaking, but the rope may move too fast when retracting and retracting. , thereby damaging the device

Abstract

The invention relates to the technical field of cranes, and discloses a crane capable of preventing lifting rope from shaking and realizing stall self-locking during winding for small size weight. Thecrane comprises a winding device, wherein a rotating shaft is movably connected inside the winding device. By means of the combined action of a sleeve set, a rope, a coil spring and a fixing block, before the weight is lifted by the device, the rope is short and is wrapped by the sleeve set, and the weight is convenient to hook; by means of the combined action of the sleeve set, the sleeve set iscontracted by the action of the winding device, and fully wraps the stretching part of the rope, and it is guaranteed that the weight does not shake when the lifted weight moves; by means of the combined action of a baffle and a clamping plate, positioning and buffering functions are achieved on the rope when the rope is stretched and wound; and by means of the rotating shaft, and a swinging rod,a cam, and a ratchet wheel, the rotating shaft is prevented from rotating, the winding device is effectively protected, and too fast operating speed is avoided so that the equipment is worn and the service life is reduced.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a small crane for heavy objects that prevents the sling from swaying and stalls and self-locks when rewinding. Background technique [0002] Cranes are hoisting machinery used for vertical lifting and horizontal handling of heavy objects. They are widely used in factories, freight yards, warehouses, ports and other places. According to the structure and performance of cranes, they can be divided into light and small, bridge type, jib type and There are four types of cable type, which bring great convenience to the development of industrial production and construction industry. Cranes are usually composed of three parts: frame, mechanism and control system. The ropes of the crane play an indispensable role in this process. At present, the ropes of the crane have the following problems when they are used: [0003] Generally, the crane transports small heavy objects, and the machine...
