Fixed rotation type crane hanging hook fixation apparatus

Abstract

The present invention relates to a fixed rotation type crane hanging hook fixation apparatus, which comprises a driving motor, a gear box, rotation plates and a connection rod, wherein the driving motor and the gear box are fixed on a crane hanging arm, the driving motor is connected to the rotation shaft through the gear box, the rotation plates are connected to both sides of the rotation shaft,both sides of the crane hanging arm are provided with electric pushing rods, the rotation plates are provided with positioning holes, one side of the rotation plate is provided with an opening groove,and the connection rod is fixed on both sides of a crane hanging hook. According to the present invention, the driving motor drives the rotation plate to rotate so as to make the connection rod be snapped into the opening grooves of the rotation plates, such that the crane hanging hook is automatically lifted and fixed, and the safety of the crane is improved; and the electric insertion pin on the crane hanging arm is inserted into the positioning hole to fix the rotation plate, such that the continuous applying of the weights of the rotation plate and the crane hanging hook on the rotation shaft can be prevented, the damage on the gear box can be reduced, and the maintenance cost can be saved.

Description

technical field [0001] The invention relates to crane equipment, in particular to a fixed and rotating crane hook fixing device. Background technique [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 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] On the same day, the applicant applied for a patent titled "A Rotary Crane Hook Fixing Device", which solved the above problems, but still required that the weight of the crane hook and the rotating plate be all applied to the rotating shaft. It will cause damage to the gearbox, and the maintenance cost of the gearbox is h...
