In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a crane span structure supports uses fixed screw, includes first fixed plate, second fixed plate, screw rod and nut, all set up threaded hole on first fixed plate and the second fixed plate, the screw rod screw thread is installed in two threaded holes, nut fixed mounting is in the screw rod upper end, nut circumference is provided with a plurality of spacing teeth, nut up end central point puts the department and has seted up the mounting groove, the standing groove has been seted up to the terminal surface under the screw rod, movable mounting has the ball in the standing groove.
Preferably, the diameter of the notch of the placing groove is smaller than that of the ball.
Preferably, the lower end face and the side wall of the screw are subjected to rounding and chamfering treatment.
Preferably, the mounting groove is a straight groove, a cross groove, a plum blossom groove, a triangular groove or an inner hexagonal groove.
Preferably, the screw, the nut and the limit teeth are manufactured by adopting an integral forming manufacturing technology.
Preferably, the screw, the nut and the limit teeth can be made of galvanized carbon steel or stainless steel or copper and copper alloy materials.
The utility model has the advantages that:
1. through setting up standing groove and ball, draw the cable through the tractor in the external world and remove in the cable testing bridge when, both can avoid screw fish tail cable, can reduce the frictional force between cable and the crane span structure when the cable slides in the crane span structure again to improve the efficiency of laying of cable.
2. Through setting up spacing tooth and spacing hole cooperation, after the screw installation finishes, utilize the card and the effect in spacing tooth and spacing hole, can prevent that the screw from sliding to the stability of being connected between crane span structure and the connecting piece has been improved.
To sum up, the utility model discloses a set up the standing groove on the screw to set up the ball in the standing groove, both can avoid screw fish tail cable, can reduce again the gliding frictional force of cable in the crane span structure, thereby improve the efficiency of laying of cable, can prevent that the fixed screw from sliding through the cooperation of thinking spacing tooth and spacing hole on the nut, thereby improved the stability of being connected between crane span structure and the connecting piece.
