Summary of the invention
The purpose of this utility model be to provide a kind of can the positive lock coupler body in lifting weight process, effectively prevent the suspension hook that coupler body rotates.Simultaneously, the utility model also provides a kind of hoisting crane that uses this suspension hook.
For achieving the above object, the technical scheme of the utility model suspension hook is: a kind of suspension hook, comprise lifting beam with hook and rotate the coupler body that is assemblied on the lifting beam with hook, described suspension hook also comprises the lock piece that is arranged on the lifting beam with hook and is fixed on the coupler body and is positioned at the spline locking disk of lifting beam with hook below, and this spline locking disk is provided with for lock piece and inserts the hole or the groove that prevent that coupler body from horizontally rotating.
Described groove is the slot that is opened on the spline locking disk side face.
Be installed with transition piece on the described lifting beam with hook, one end of described lock piece is hinged on the transition piece, the plane that the jointed shaft of lock piece consists of perpendicular to the axis of the axis of lifting beam with hook and spline locking disk, the other end of lock piece be lock piece when described jointed shaft rotates to the spline locking disk with the spline locking disk on slot insert the insertion end that cooperates.
Described transition piece is provided be used to preventing that the lock piece insertion end breaks away from the disconnecting prevention structure of slot.
Described disconnecting prevention structure is the block pin that cooperates with lock piece outer side edges block.
The technical scheme of the utility model hoisting crane is: a kind of hoisting crane, comprise suspension hook, suspension hook comprises lifting beam with hook and rotates the coupler body that is assemblied on the lifting beam with hook, described suspension hook also comprises the lock piece that is arranged on the lifting beam with hook and is fixed on the coupler body and is positioned at the spline locking disk of lifting beam with hook below, and this spline locking disk is provided with for lock piece and inserts the hole or the groove that prevent that coupler body from horizontally rotating.
Described groove is the slot that is opened on the spline locking disk side face.
Be installed with transition piece on the described lifting beam with hook, one end of described lock piece is hinged on the transition piece, the plane that the jointed shaft of lock piece consists of perpendicular to the axis of the axis of lifting beam with hook and spline locking disk, the other end of lock piece be lock piece when described jointed shaft rotates to the spline locking disk with the spline locking disk on slot insert the insertion end that cooperates.
Described transition piece is provided be used to preventing that the lock piece insertion end breaks away from the disconnecting prevention structure of slot.
Described disconnecting prevention structure is the block pin that cooperates with lock piece outer side edges block.
Lock piece of the present utility model is arranged on the lifting beam with hook, the spline locking disk is fixed on the coupler body, just can make the relative lifting beam with hook of coupler body static behind hole on the lock piece insertion spline locking disk or the groove, can lock coupler body by failure-free in lifting goods process, actv. prevents that the relative lifting beam with hook of coupler body from horizontally rotating.
Further, slot is arranged on the side face of spline locking disk after, can utilize a rotating lock piece to insert from the side slot and realize locking, simple and compact for structure being easy to realized.
Further, disconnecting prevention structure is set after, can prevent that lock piece breaks away from slot, makes the locking of suspension hook more reliable.
Description of drawings
Fig. 1 is the structural representation of suspension hook part among a kind of embodiment of the utility model hoisting crane;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The embodiment of the utility model hoisting crane comprises monkey and is positioned at monkey below suspension hook, the structure of suspension hook as depicted in figs. 1 and 2, suspension hook comprises lifting beam with hook 1, rotate the coupler body 4 be assemblied on the lifting beam with hook, be arranged on the lock piece 2 on the lifting beam with hook 1 and be fixed on the spline locking disk 3 that is positioned at the lifting beam with hook below on the coupler body 4, spline locking disk 3 is provided with and supplies lock piece 2 to insert the groove that prevents that coupler body 4 from horizontally rotating, and this groove is the slot that is opened on spline locking disk 3 side faces.Be installed with transition piece on the lifting beam with hook 1, one end of lock piece 2 is hinged on the transition piece, the plane that the jointed shaft of lock piece 2 consists of perpendicular to the axis of the axis of lifting beam with hook and spline locking disk, the other end of lock piece be lock piece when described jointed shaft rotates to coupler body with the spline locking disk on slot insert the insertion end that cooperates.Also be provided with on the transition piece be used to preventing that lock piece 2 insertion ends break away from the disconnecting prevention structure of slot, this disconnecting prevention structure is the block pin that cooperates with lock piece outer side edges block.
Present embodiment only needs to promote lock piece 2 lock piece 2 is stuck on the groove on the spline locking disk 3 in use, and coupler body 4 is fixed on the lifting beam with hook 1, after coupler body 4 locks, makes the locking of coupler body more reliable with fixedly locked 2 of block pin.
