Roller 302, the first conveying roller 302 rotates around the first conveying roller shaft to support and convey the cable.

After the inclined hollow rod 301 is placed on the ground, due to the frictional force between the inclined hollow rod 301 and the ground, it is difficult for the inclined hollow rod 301 to rotate on the short rope 202, and the plurality of first conveying rollers 302 are evenly distributed. It is arranged on the inclined hollow rod 301, so that the first conveying roller 302 located on the top of the inclined hollow rod 301 can rotate normally without being affected by the ground, so that the resistance during cable transportation is small, so as to achieve the purpose of carrying and conveying the cable.

The positive position conveying member 4 includes a positive position rod 401, and the radial direction of the positive position rod 401 is provided with two sets of through holes 402 (when the positive position rod 401 is a solid rod, a set of through holes 402 is a single hole, and the positive position rod 402 is hollow. When the rod is used, a set of through holes 402 are two symmetrical holes), and the two adjacent long ropes 201 between the two sets of rope groups 2 pass through the through holes 402 respectively to fix the alignment rod 401 on the long rope 201 . Both ends of the alignment rod 401 are screwed with first set screws 403 , and the long rope 201 is fixed in the through hole 402 by the first set screws 403 . Both ends of the alignment rod 401 are provided with second annular end plates, and the circumferential direction of the second annular end plate is distributed with a second conveying roller shaft parallel to the axis of the alignment rod 401; both ends of the second conveying roller shaft are respectively fixed on the two second annular end plates.

In special circumstances, for example, the lengths of the two long ropes 201 in the rope set 2 are different, at this time, the longer long rope 201 can be extended a part from the light hole, so that the rope set 2 can be located between two Parts of the section of the adjusting device 1 have the same length, that is, by adjusting the extension length of the long rope 201 in the moving block 104 , the problem of different lengths of the long rope 201 between the fixed plates 101 is solved.

The short rope 202 is bound or fixed on the long rope 201 by a fixing fixture. No matter which fixing method is adopted, it is necessary to ensure that the short rope 202 can be re-fixed on the long rope 201 after being separated from the long rope 201. The above fixing method is as follows: The conventional technology will not be described in detail. When the inclined conveying member 3 is damaged, one end of the short rope 202 running through the interior of the inclined conveying member 3 can be separated from the long rope 201, and the inclined conveying member 3 can be removed, and then sleeved. After the new oblique conveying member 3 , the short rope 202 can be re-fixed on the long rope 201 according to the original position, so as to facilitate the replacement of the oblique conveying member 3 when the oblique conveying member 3 is damaged.

The operator adjusts the adjusting device 1: rotate the two crank handles 106 corresponding to a long rope 201, so that the two moving blocks 104 on the adjusting device move in the same direction, so that one of the rope groups 2 is moved in the same direction. When the long rope 201 moves along its own extension direction, when the other long rope 201 does not move or moves in the opposite direction, the inclination direction of the inclined conveying member 3 on the rope group 2 is changed. The other rope group 2 is adjusted in the same way to change the inclination direction of the upper inclined conveying member 3, so that the purpose of adjusting the inclination angle of the inclined conveying member 3 through the adjusting device 1 can be realized, thereby changing the cable conveying suitable for this device. direction.
