Abstract
The utility model relates to tooling clamps used in lifting process and in particular relates to an anti-rotating lifting hook. The anti-rotating lifting hook comprises a lifting lug, wherein a cavity is formed in the lower part of the lifting lug; a fastening nut is arranged on a step at the lower end in the cavity; a thrust ball bearing is arranged in a mounting groove on an upper end face of the fastening nut; a connecting part at the upper end of the lifting hook sequentially penetrates through an inner hole of the fastening nut and a bearing hole of the thrust ball bearing and stretches into an inner cavity of the lifting lug; a rotating nut is sleeved on the connecting part in which the lifting hook stretches into the inner cavity of the lifting lug; the lower part of the rotating nut is pressed on an upper end face of the thrust ball bearing. A connecting part of the anti-rotating lifting hook and a steel wire rope is not fixed, and after the steel wire rope is stressed to straighten and the lifting hook rotates, the torque in the steel wire rope can be released under the condition that the lifting hook does not rotate, so that hidden danger brought by rotation of the lifting hook in the operating process is avoided, and unnecessary losses are reduced.
Description
Technical field
The utility model relates to the frock clamp using in hoisting process, specifically a kind of anti-rotation suspension hook.
Background technology
Suspension hook rotation be usually without any omen occur in equipment hoisting operation, when elevator machinery is sling after weight, suspension hook rotates, wear around the steel rope between suspension hook and arm top block group and tussle together, the weight being lifted also rotates with suspension hook, at this moment can not continue sling or put down the weight of having sling.Suspension hook rotation can affect normally carrying out of lifting operation, seriously threatens the safety of operating personnel and equipment, therefore must avoid its generation.
The steel rope that elevator machinery uses all can produce moment of torsion when stressed.Moment of torsion is that the manufacture due to steel rope causes, be twisted together before this steel wire spiral and form thigh, then several strands are twisted together spirally again and form steel rope.After stressed, steel wire can be straightened, but the termination of steel rope is fixed wtih during lifting operation, has just formed like this moment of torsion in steel rope.Another root that forms moment of torsion be steel rope pitch is elongated in use for some time, thereby make it in end fixedly in the situation that, the not stressed moment of torsion that just produced of steel rope, the existence of moment of torsion makes hook assembly have the trend of rotation.
There are on the other hand many external factor directly to cause suspension hook rotation, external force such as the manpower in hoisting process or wind-force promotes suspension hook and rotates, the unstable consequently suspension hook of driver operation and weight swing and cause suspension hook rotation, and wearing around mode of suspension hook causes suspension hook overbalance to cause suspension hook rotation etc.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of anti-rotation suspension hook, can in the non-rotary situation of suspension hook, the torque in steel rope be discharged.
According to the technical solution of the utility model: a kind of anti-rotation suspension hook, it is characterized in that: comprise hanger, described hanger bottom offers cavity, described inside cavity lower end step is provided with clamp nut, thrust ball bearing is installed in the mounting groove of described clamp nut upper surface, suspension hook upper end connecting portion stretches into hanger inner chamber after the bearing hole through clamp nut endoporus and thrust ball bearing successively, and described suspension hook stretches on the connecting portion of hanger inner chamber and is arranged with the nut of turning, described in the nut bottom of turning be installed with in thrust ball bearing upper surface.
As further improvement of the utility model, described anti-rotation suspension hook also comprises a clump weight, and clump weight is sheathed on described hanger, and clump weight upper end closing in portion is supported in hanger upper end shoulder simultaneously.
As further improvement of the utility model, between described clamp nut and hanger, by holding screw, be connected.
As further improvement of the utility model, between described clump weight and hanger, by pin for suppressing metal, be locked.
Technique effect of the present utility model is: the utility model anti-rotation suspension hook and steel rope connecting portion are not fixed, after the stressed stretching generation suspension hook rotation of steel rope, can in the non-rotary situation of suspension hook, the torque in steel rope be discharged, thereby prevent the hidden danger that in operation process, suspension hook rotation brings, reduce unnecessary loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, comprise hanger 1, clump weight 2, the nut 3 of turning, thrust ball bearing 4, clamp nut 5, suspension hook 6 etc.
As shown in Figure 1, the utility model is a kind of anti-rotation suspension hook, comprise hanger 1, described hanger 1 bottom offers cavity, described inside cavity lower end step is provided with clamp nut 5, thrust ball bearing 4 is installed in described clamp nut 5 upper surface mounting grooves, suspension hook 6 upper end connecting portions stretch into hanger 1 inner chamber after the bearing hole through clamp nut 5 endoporus and thrust ball bearing 4 successively, and described suspension hook 6 stretches on the connecting portion of hanger 1 inner chamber and is arranged with the nut 3 of turning, described in nut 3 bottoms of turning be installed with in thrust ball bearing 4 upper surfaces.
Described anti-rotation suspension hook also comprises a clump weight 2, and clump weight 2 is sheathed on described hanger 1, and clump weight 2 upper end closing in portions are supported in hanger 1 upper end shoulder simultaneously.
Between described clamp nut 5 and hanger 1, by holding screw, be connected.
Between described clump weight 2 and hanger 1, by pin for suppressing metal, be locked.
The utility model anti-rotation suspension hook and steel rope connecting portion are not fixed, after the stressed stretching generation suspension hook rotation of steel rope, can in the non-rotary situation of suspension hook, the torque in steel rope be discharged, thereby prevent the hidden danger that in operation process, suspension hook rotation brings, reduce unnecessary loss.
