Rotation type crane hanging hook fixation apparatus

Abstract

The present invention relates to a rotation type crane hanging hook fixation apparatus, which comprises a driving motor, a gear box, rotation plates and connection rods, wherein the driving motor andthe gear box are fixed on a crane hanging arm, the driving motor is connected to a rotation shaft through the gear box, the rotation plates are connected to both sides of the rotation shaft, one sidesof the rotation plates are provided with opening grooves, the connection rods are fixed on both sides of a crane hanging hook, and the rotation type crane hanging hook fixation apparatus drives the rotation plates to rotate through the driving motor, such that the connection rods are snapped into the opening grooves of the rotation plates so as to automatically lift and fix the crane hanging hookand improve the safety of the crane.

Description

Technical field [0001] The invention relates to crane equipment, in particular to a rotary crane hook fixing device. Background technique [0002] The top of the crane's boom is connected to the hook by a rope. When the crane is moving, if the hook is not fixed, the hook will swing under the action of inertia, which is quite uneasy. At present, the traditional fixing method is to hook the hook. A rope is hung on and hooked on the frame of the crane through the rope. In this way of fixing, the sling is tightened, and the sling is in a tight state for a long time, which is easy to damage the sling and poses a safety hazard. [0003] The applicant applied for a patent named "a crane hook fixing device" on the same day, which solves the above-mentioned problems, but still requires manual fixing, which is troublesome in operation. Summary of the invention [0004] In view of the above shortcomings, the applicant has carried out research and improvement to provide a rotary crane hook fix...

Problems solved by technology

[0002] The top of the boom of the crane is connected to the hook by a sling. When the crane is running, if the hook is not fixed, the hook will swing under the action of inertia, which is quite disturbing. At present, the traditional fixing method is to fix the hook A rope is hung on the top, and the rope is hooked to the frame of the crane. In this fixing method, the rope is tightened, and the rope is in a tight state for a long time, which is easy to damage the rope and poses a safety hazard.

[0003] The applicant applied on the same day for a patent titled "A Crane Hook Fixing Device", which solves the above problems, but still requires manual fixing, which is cumbersome to operate.
