The principle of operation of the present invention will now be described as follows:
Firstly, a worker places a polished cable into a placing groove 33 formed in the upper surface of a repairing table 32, then starts a third electric push rod 31, enables the output end of the third electric push rod 31 to drive the repairing table 32 to move upwards until a first push switch 74 and a second push switch 75 are positioned in a defect of a cable buffer layer, at the moment, an arc-shaped fixing plate 36 repairs and fixes the outer surface of the cable, because the first push switch 74 and the second push switch 75 are respectively electrically connected with a first electric push rod 3 and a second electric push rod 4, and the first electric push rod 3 and the second electric push rod 4 are electrically connected with a plc controller 35, at the moment, the first electric push rod 3 and the second electric push rod 4 are simultaneously started by the plc controller 35, and because the output ends of the first electric push rod 3 and the second electric push rod 4 are fixedly connected with a support plate 5, the outer walls of the support plate 5 are fixedly connected with the third fixing plate 34, the outer walls of the two third fixing plates 34 are respectively and fixedly connected with the first push switch 74 and the second push switch 75 through the first fixing plate 71, the compensating spring 72 and the second fixing plate 73, at this time, the first push switch 74 and the second push switch 75 can move in the defect position of the cable buffer layer, if the first push switch 74 moves to the edge of the defect position of the cable buffer layer first, the first electric push rod 3 stops working at this time, and the second push switch 75 moves to the opening of the defect position of the cable buffer layer, at this time, the second electric push rod 4 stops working under the action of the second push switch 75, and because the third electric push rod 31 is electrically connected with the plc controller 35, at this time, the third electric push rod 31 can drive the cable to generate partial downward movement, so that the first push switch 74 and the second push switch 75 are prevented from contacting with repairing liquid, the opening size of the defect part of the cable buffer layer can be determined in the process, so that the repair range can be controlled, only the damaged part is repaired, and the integrity and balance of the cable can be maintained;
In the process that the first electric push rod 3 and the second electric push rod 4 drive the support plate 5 to move, as the outer walls of the support plate 5 are fixedly connected with the rack 19 through the first connecting rod 17, and the glue outlet box 9 and the U-shaped connecting plate 8 are arranged above the U-shaped shell 1, the same threaded rod 11 is rotationally connected to the outer walls of the U-shaped shell 1 and the glue outlet box 9, and the gears 16 meshed with the rack 19 are fixedly connected to the outer walls of the two threaded rods 11, the rack 19 drives the threaded rod 11 to rotate through the gears 16 when the support plate 5 moves, and as the threaded rod wall of the threaded rod 11 is in threaded sleeve joint with the threaded slider 12, the lower end of the threaded slider 12 is fixedly connected with the first piston plate 10 through the support rod 15, in the process that the threaded rod 11 drives the threaded slider 12 to move downwards, at the moment, the repairing glue in the two glue outlet boxes 9 can flow into the same first glue outlet pipe 20 through the third glue outlet pipe 23, the glue outlet quantity of the glue outlet boxes 9 is in proportion to the opening of the defect of a cable buffer layer, so that the filling quantity is high, the quality can not be enough, the quality of the repairing material can not be controlled, the quality of the repairing quality can not be sufficiently high, and the quality can not be sufficiently controlled, and the quality of the repairing quality can not be can be realized;
Because the outer walls of the support plates 5 are fixedly connected with the glue blocking plates 25, when the first electric push rod 3 and the second electric push rod 4 stop working, at the moment, the two support plates 5 can drive the glue blocking plates 25 to block the glue outlet of part of the second glue outlet pipe 22, because the plc controller 35 is electrically connected with the electromagnetic valve 24, the plc controller 35 controls the electromagnetic valve 24 to enable repair glue to flow out through the second glue outlet pipe 22, at the moment, the glue outlet area of the second glue outlet pipe 22 is in direct proportion to the opening size of the defect part of the cable buffer layer, the consistency of the repair effect can be improved, when the opening of the defect part of the cable buffer layer is repaired, the first electric push rod 3 and the second electric push rod 4 can be controlled to reset under the action of the plc controller 35, the proper glue outlet area can ensure the sufficient coverage and filling of repair materials, not only reduces the time required by the repair process, but also avoids the problems of overlapping with other part glue layers, such as insulation deformation in the joint, even short circuit, partial discharge and the like;
In the repair process of the defect of the cable buffer layer, under the action of the first electric push rod 3 and the second electric push rod 4, the two support plates 5 move outwards, as the connecting frame 26 is arranged on the outer wall of the rectangular frame 2, and the marking box 27 is arranged in the connecting frame 26, when the support plates 5 move outwards, the marking liquid in the marking box 27 flows down to the outer wall surface of the cable through the marking pipe 30 under the pushing of the second piston plate 28, marks are made on the repair position of the cable, the quantity of the flowing marking liquid is in proportion to the size of the gap of the buffer layer, a reference standard can be provided for future maintenance and overhaul work, and when a repair area needs to be further processed or evaluated, proper operation and measures can be determined by referring to the marking and the opening size.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
