The embodiment provides a winding reinforcing device for repairing a broken strand of a power transmission line, which comprises a clamping mechanism 1, a wire winding disc 2 and a rotary moving mechanism (not shown in the figure) as shown in fig. 1. The clamping mechanism 1 is arranged at the starting end of the pre-twisted wire and clamps the pre-twisted wire according to the shape of the pre-twisted wire. The wire winding disc 2 is driven by the rotary moving mechanism to rotate and move in the axial direction of the wire, and then the pre-twisted wire is wound on the wire.
As shown in fig. 2 to 4, the winding reel 2 is penetrated by a pre-twisted wire and a wire, and includes a wire area 21, a pre-twisted wire area 23, and a fixing area 25 which are connected in this order in a direction away from the clamping mechanism 1.
The wire area 21 is sleeved on the wire and is of a cone-barrel-shaped structure, the radius of the wire area increases in sequence along the direction away from the clamping mechanism 1, the guide groove 22 is formed in the middle of the wire area, the guide groove 22 is spiral and used for fixing the wire to the guide groove 22 after the pre-twisted wire is wound, and meanwhile, in the winding process, the wire passes through the wire winding disc 2 through the guide groove 22.
Because the torque required in the ending stage of the wire winding is larger, a frustum provided with a guide groove is added behind the wire winding disc 2, so that the preformed armor rods can be continuously stressed after being separated from the clamping seams in the final stage, and the ending work can be well finished. In order to make the thread protecting strip fall into the guide groove 22 after leaving the clamping seam, the shape of the guide groove 22 is the same as that of the preformed helical thread, and the preformed helical thread is helical, so that the guide groove is also helical with a thread pitch, a lead and a base radius slightly larger than that of the repairing strip.
The pre-twisted wire area 23 is used for being sleeved on all pre-twisted wires, is annular, is circumferentially provided with a plurality of clamping seams 24, the clamping seams 24 are conical in axial cross section, and each clamping seam 24 is sleeved with an individual pre-twisted wire. Under the action of torque, the preformed armor rods can slide to the direction of the conducting wire, namely the small end of the clamping seam 24, and the self-locking is realized under the action of the torque. The width of the slot 24 is gradually increased along the direction far away from the guide groove 22, so that the repair strip with different wire diameters can be suitable, and the repair strip can be limited within a certain range when the repair strip is rotated to different positions.
The fixing region 25 is annular as a region connected to the clamp ring 3.
The forming head 2 comprises two identically constructed modules, each of which comprises half of the wire area 21, the pre-twisted wire area 23 and the fixing area 25, which are connected by means of a clamping ring 3 as shown in fig. 6, but can also be connected in a tight manner in other ways.
As shown in fig. 5, the clamping mechanism 1 includes two connected semicircular clamping arcs 11 with openings, and the two clamping arcs 11 are connected with the openings facing each other to form a ring-shaped clamping mechanism 1.
The inner wall circumference of clamping mechanism 1 is equipped with a plurality of draw-in grooves 12, and the shape of draw-in groove 12 is crooked structure for clamping mechanism 1's axial direction, and the camber is with the shape looks adaptation of stranded conductor in advance, during the use, with two front ends and the lock of tight arc 11 alignment stranded conductor in advance for every stranded conductor in advance cooperatees with the draw-in groove 12 that corresponds, and adopts hydraulic tong with both zonulae occludens, perhaps adopts the welded mode to make two tight arcs 11 of clamp connect.
The shape of the clamping groove 12 is just matched with the front end of the repairing strip, the front part is shallow and the back part is deep (the preformed armor rods are spiral and are convenient to fix, and the front end of the placing position is basically attached to a lead, namely, the circular axis of the end face is parallel to the lead, but because the spiral shaft of the preformed armor rods is not parallel to the central axis of the lead, the back part naturally diverges outwards, so the shape of the clamping groove of the back part is deep and is about 3/4 of the diameter of the preformed armor rods), and the clamping groove is deep and is more than half of the diameter of the preformed armor rods, so that the repairing strip can be well limited and fixed.
The rotary moving mechanism is a worm and gear mechanism or a screw nut transmission mechanism, and the embodiment is the worm and gear mechanism.
The embodiment of the invention is as follows: the clamping mechanism 1 clamps the initial section of the preformed armor rods, and the initial ends of the preformed armor rods are placed in close contact with the conducting wires in a wound state. The clamping ring 3 locks the forming disc 2 so that the two parts are integrated. The preformed armor rods rotate along the bending direction of the preformed armor rods under the driving of the worm and gear mechanism, meanwhile, the worm rods move forwards along the sliding rails under the driving of the motor, and drive the wire winding disc 2 and the worm gear to move forwards while rotating, so that the preformed armor rods are gradually and completely wound on the wires. And in the ending stage, the preformed armor rods enter the guide groove 22 after being separated from the clamping seam 24, the diameter of the lead area 21 is gradually reduced in the forward moving process, and the tail parts of the preformed armor rods are gradually attached to the leads along with the movement of the lead area 21, so that the winding and reinforcing functions are completed.
Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
