Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

Referring to fig. 1 and 2, an embodiment of the utility model provides cable hoisting equipment for a cable-stayed bridge, which comprises an underframe 1, wherein a support frame 2 is welded at the left end of the underframe 1, a central shaft 3 is installed at the upper end of the support frame 2 in a threaded manner, two guide wheels 4 are rotatably installed on the central shaft 3 through bearings, a hoisting shell 5 is installed at the upper end of the underframe 1 through bolts, a servo motor 6 and a winding drum 7 are installed at the upper end of the hoisting shell 5 through bolts, the model of the servo motor 6 is 80HB-02430, a rotor shaft of the servo motor 6 is in transmission connection with the winding drum 7 through a belt and a belt wheel, two ropes 8 are wound on the winding drum 7, and the left ends of the two ropes 8 are connected with clamping mechanisms 9 by bypassing the two guide wheels 4 and used for hoisting the clamping mechanisms 9 to move up and down.

Referring to fig. 1, 2 and 3, a rubber pad 10 is glued to the lower end of the hoisting shell 5, so as to achieve the functions of damping vibration and reducing noise. The middle of the winding drum 7 is welded with the partition board 11, and the two ropes 8 are wound on the front side and the rear side of the partition board 11 respectively, so that the two ropes 8 can be prevented from being wound together. The clamping mechanism 9 comprises two fixing blocks 901, a guide rod 902 is installed between the two fixing blocks 901 in a threaded mode, two clamping blocks 903 are sleeved on the guide rod 902 in a sliding mode, a bearing seat 904 is welded at one end, close to the fixing block 901, of the clamping block 903, an internal threaded pipe 905 is installed in the bearing seat 904 in a rotating mode, a threaded column 906 is welded at one end, close to the bearing seat 904, of the fixing block 901, the internal threaded pipe 905 is in threaded connection with the threaded column 906, the distance between the two clamping blocks 903 is adjusted, and therefore a cable can be clamped conveniently.
