Fixing device and fixing method for a hook block of a marine crane

Abstract

The invention relates to a marine crane hook pulley fixing device and fixing method and belongs to the technical field of machinery. The marine crane hook pulley fixing device comprises a control mechanism and a performing mechanism. The control mechanism comprises an automatic reset hydraulic cylinder and a control device thereof. The performing mechanism comprises a locking pin and a poking rod which is fixed to the end of the locking pin and located on the outer side of connection plates. The locking pin is arranged in an installation hole in a penetrating-inserting mode. The tail end of the poking rod is hinged to the tail end of a piston rod of the automatic reset hydraulic cylinder. The locking pin is provided with a buckle part. A locking buckle plate is fixed to the upper portion of the pulley and is provided with a clamping groove matched with the buckle part of the locking pin. A limiting plate and a baffle are fixed between the two connection plates. The limiting plate is abutted against the side, far away from the locking pin, of the locking buckle plate. The baffle is arranged at the top of the locking buckle plate and is abutted against the locking buckle plate. The fixing method comprises the steps that the control mechanism is started to drive the performing mechanism to act, and the control mechanism is stopped. Compared with the existing manual locking mode, the safety is ensured, the operation efficiency is improved significantly, and locking fixation can be achieved fast.

Description

technical field [0001] The invention relates to a hook block fixing device and a fixing method of a marine crane, belonging to the technical field of machinery. Background technique [0002] The hoisting mechanism of the crane includes a hook group, and the hook group usually includes a main hook and an auxiliary hook, and the main and auxiliary hooks work together to improve lifting efficiency. If the existing marine crane has a main hook and an auxiliary hook, because when the distance between the main hook block and the auxiliary hook is close, interference is likely to occur. In order to prevent this from happening, the operation requires that when the main hook is working, the auxiliary hook is fixed and the auxiliary hook is working. , the main hook is fixed. Patent No. 201520691818.2 discloses a main hook block fixation and quick release device, which can realize the fixation of the hook block, but it needs to manually toggle the handle and insert the fixing pin to f...
