The invention also provides a using method of the clamping device for repairing the cable, which comprises the following steps:
s1, placing two sliding bases 1 on two sides of a cable 3;
s2, adjusting the height of the cable clamping components 5, and then completing the buckling of the two cable clamping components 5 on the cable 3 at two sides of the cable 3.
S3, driving the cable clamping component 5 to clamp the cable 3;
s4, starting the moving component 2, and pulling out the cables 3 positioned at the two sides of the two cable clamping components 5 for a certain distance, so that the subsequent lifting of the cables 3 is facilitated;
s5, starting the vertical pulling component 4, and pulling up the cable 3;
s6, the support of the L-shaped connecting rod 207 by the abutting rod 206 is released, and the middle part of the cable 3 is lifted and straightened under the pressing action of the weight of the cables on the two sides of the cable 3.
The working principle is as follows: with reference to fig. 1, 2, 6 and 8, the two sliding bases 1 are placed on two sides of the cable 3, then the second driving member 406 is started to drive the second gear 405 to rotate, and the two third rack bars 403 are lowered to the position of the cable 3 to drive the cable clamping member 5 to move downward together, then the second ring 506 and the first ring 512 rotate to open the opening part, the cable 3 is placed in the middle of the second ring 506 to align with the two engaging lugs 521, and the two engaging lugs 521 are fastened by bolts.
With reference to fig. 4 and fig. 9, the third driving member 502 is started, the third driving member 502 drives the first rotating shaft 504 to rotate, so as to drive the third gear 505 to rotate, the third gear 505 rotates to drive the incomplete gear ring 509 to rotate, so as to drive the second ring 506 to rotate, and the second ring 506 rotates to drive the two clamping block sets to rotate towards the corresponding pushing block sets. When the arc-shaped pushing block 522 is driven by the second ring 506 to rotate to contact with the arc-shaped surface of the clamping block 514, the arc-shaped pushing block 522 rotates along with the second ring 506, the clamping block 514 is pressed to move in the second rectangular through hole 513 towards the cable 3, and the first spring 515 is pulled up. The clamping block 514 is pushed out until contacting the surface of the cable 3, and the second driving member 502 is driven to rotate for a certain time, so that the arc-shaped pushing block 522 continues to push the clamping block 514 out for a certain distance, thereby ensuring that the clamping block 514 and the surface of the cable 3 are clamped sufficiently. The three clamping blocks 514 in each clamping block set stably clamp the cable 3 from three directions. The two cable gripping members 5 grip both ends of the cable 3.
Referring to fig. 1 and 7, after the cable 3 is clamped, the two first driving motors 216 are started, the output ends of the first driving motors 216 rotate to drive the first gears 217 to rotate, the first gears 217 drive the first racks 214 and the second racks 215 engaged with the first gears to move towards opposite sides, the distance between the first sliding blocks 201 and the second sliding blocks 202 is shortened, the first sliding blocks 201 and the second sliding blocks 202 in the two sliding bases 1 respectively pull the cable 3 towards the middle from two ends, both sides of the cable 3 are pulled out by a certain distance, and the elongation of the cable 3 when the arc lifts up is ensured. After the cable 3 is pulled out by a sufficient distance, the first driving motor 216 is driven to move the first sliding block 201 and the second sliding block 202 back to the initial position.
And then, reversely starting the two second driving parts 406 to respectively drive the two third rack bars 403 to synchronously move upwards to drive the two cable clamping parts 5 to move upwards together, and stopping the second driving parts 406 after the cable 3 is lifted to a position where a person can repair the cable 3 subsequently.
Referring to fig. 1 and 5, the shifting rod 212 on each of the first sliding block 201 and the second sliding block 202 is rotated away from the stop block 213, and then the shifting rod 212 is rotated to rotate the L-shaped stop 210 upward for a certain distance to contact with the limit of the abutting rod 206, when the L-shaped connecting rod 207 loses its supporting force of the abutting rod 206, under the gravity of the cable 3 located at the outer part of the two cable clamping components 5, the two L-shaped connecting rods 207 at the left side are rotated and fallen down for a certain angle toward the left side, and the two L-shaped connecting rods 207 at the right side are rotated and fallen down for a certain angle toward the right side, so as to rotate and lift the two cable clamping components 5 inward, at this time, because the position of the square housing 401 is moved backward along with the falling of the two L-shaped connecting rods 207, the cable clamping components 5 rotate inward, the middle of the cable 3 will be stretched straight until the cable 3 stretches over and pulls the two cable clamping components 5, therefore, two L-shaped connecting rods 207 corresponding to each side are pulled to be incapable of being turned over continuously, and at the moment, the part of the cable 3 to be repaired is raised and straightened at the same time, so that the subsequent repair is greatly facilitated.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
