Auxiliary rope-chasing structure for four-rope grab bucket

Abstract

The invention discloses an auxiliary rope-chasing structure for a four-rope grab bucket, and relates to the technical field of four-rope grab buckets. The auxiliary rope-chasing structure for the four-rope grab bucket comprises a hoisting mechanism and a top plate, wherein a grab bucket body is arranged at the bottom of the top plate; and an opening-closing steel wire rope is arranged on the top plate in a penetrating manner. According to the auxiliary rope-chasing structure for the four-rope grab bucket, a tension detection mechanism is additionally arranged, and a winding mechanism is improved, so that an independent rope-chasing system is provided; when the grab bucket is completely pulled up, a winding reel is driven to rotate relatively through the rotation of a drive mechanism and a transmission gear, so that the opening-closing steel wire rope is fastened, and then the rope-chasing effect is achieved, the dislocation of the opening-closing steel wire rope is avoided well, and the working efficiency is increased while the construction safety is guaranteed; meanwhile, the structure needed by improvement is simple, and the manufacturing cost is relatively low; and meanwhile, improvement is carried out on the basis of the existing four-rope grab bucket, so that the case of discarding of the existing grab bucket cannot occur, and the improvement cost is saved to a great extent.

Description

technical field [0001] The invention relates to the technical field of four-rope grabs, in particular to an auxiliary rope tracking structure for a four-rope grab. Background technique [0002] The grab bucket refers to the special tool for the crane to grab dry bulk cargo. The storage space is composed of two or more bucket-shaped jaws that can be opened and closed. When loading, the jaws are closed in the material pile, and the materials are grabbed into the storage space. When unloading, the jaws are in the pile. When it is opened in the suspended state, the material is scattered on the pile, and the opening and closing of the jaw plate is generally controlled by the steel wire rope of the hoisting mechanism of the crane. There is no heavy manual labor in the grab operation, which can achieve high loading and unloading efficiency and ensure safety. It is the main dry bulk cargo loading and unloading tool in the port. According to the type of operating cargo, it can be d...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an auxiliary rope tracking structure for a four-rope grab, which solves the problem of grabbing due to misalignment of the opening and closing wire ropes when the four-rope grab is used in the prior art. The situation that the grab cannot be completely closed (when the grab is grabbing items, the grab cannot be completely closed because the items are stuck in the mouth of the grab. Grabbing operation, the grab cannot be completely closed), if the grasped object is a small particle, it is easy to cause the problem of falling the object during the grasping process
