Description

Grab bucket supports rope chain and prevents clamping device

Technical Field

The utility model relates to a hoist field, concretely relates to grab bucket supports rope chain and prevents clamping device.

Background

The grab bucket is an important goods taking tool for grabbing goods, is widely applied to port loading and unloading operation, and is particularly applied to the field of bulk goods grabbing operation, such as coal loading and unloading, ore loading and unloading, grain unloading and the like. According to the specific gravity of goods, the grab bucket can be divided into a light grab bucket and a heavy grab bucket, the grab bucket for grabbing bulk goods such as grains and chemical fertilizers belongs to the light grab bucket, and the grab bucket mostly adopts a four-rope double-jaw grab bucket.

The four-rope double-jaw grab bucket is mainly used in cooperation with a bridge or portal crane with two groups of lifting drums. Two groups of motor drums are arranged on the crane, two steel wire ropes are led out from each group of drums, wherein the two steel wire ropes (called opening and closing ropes) form a group and pass through the pulleys of the upper cross beam and the pulleys of the lower cross beam to form a pulley block, play a role of opening and closing a bucket part and are connected with the two opening and closing bucket ropes; and the other group of steel wire ropes (called supporting ropes) are connected with the grab bucket swing frame (balance beam) through corresponding supporting rope chains for supporting. The grab swing frame plays a role in fixing the supporting ropes and adjusting the difference between the two supporting ropes.

At present, in order to facilitate working conditions such as grab bucket disassembly, hook replacement, grab bucket operation and the like, winding among four steel wire ropes can be reduced in each bulk cargo wharf in the industry, a supporting rope chain is usually arranged between a supporting rope and a grab bucket swing frame to be connected. However, in the actual loading and unloading process, when the grab bucket falls on the surface of the material, the four steel wire ropes still need to continuously fall for a certain stroke to improve the full grabbing rate. At the moment, the four steel wire ropes are in a loose state, and the supporting rope chains fixed on the two sides of the grab bucket swing frame can randomly fall into the frame of the swing frame due to large dead weight. In the process that the grab bucket begins to grab materials and the steel wire rope rises to close the bucket, along with the gradual tensioning of the steel wire rope, the swing of the swing frame supports the rope chain to be clamped occasionally between the swing frame and the rope guide roller for opening and closing the bucket rope, and the rope cannot be automatically loosened. At the moment, if the grab bucket is continuously lifted, the steel wire rope is easy to wind and jump, and the steel wire rope can be seriously broken, so that safety production accidents are caused.

Chinese patent with publication number CN212050191U discloses an anti-sticking swing frame for grab bucket, which belongs to the technical field of port logistics equipment, the swing frame comprises a swing frame and a swing frame shaft fixedly arranged in the swing frame, an anti-sticking board is arranged on the upper side of the swing frame, the anti-sticking board shields the inner cavity of the swing frame, and a guide rope channel for penetrating and opening and closing a bucket rope is further arranged at the corresponding position of the anti-sticking board and a guide rope wheel set.

Above-mentioned scheme supports rope chain card in wire wheel department through putting better prevention of cardboard can, but conventional anti-sticking board all be the lug weld on the rocker frame, can reduce the space of wire wheel group maintenance for the maintenance of wire wheel group is comparatively troublesome.
