Two sets of support wheels 53 auxiliary supports to the cable rollers will not interfere with the movement of the cable rollers carried by the present invention.

When the present invention carries the installed cable roller uphill, the angle between the line between the center of the cable roller shaft section and the center of the rear wheel 3 wheel shaft section and the vertical line is greater than the gradient of the slope. Before the present invention goes uphill, first pull out the two bolts A6 to release the locking between the two beam arms A1 and the corresponding beam arms B4, and pull the two beam arms B4 to elongate relative to the beam arms A1 through the trailer, so that the rear wheels 3 The distance between the universal wheel 7 is greater than the length of the slope, the slope of the two beam arms A1 is smaller than the slope, and the two pins A6 are respectively inserted into the round pin on the corresponding beam arm A1 and the socket A5 on the beam arm B4 and Lock beam arm A1 and beam arm B4.

Return and slide downward on the vertical bar under the action of gravity.

When the cable roller reaches the ground, dial down the two driving levers 51 again, and the two driving levers 51 respectively drive the baffle plates 49 on the two slide seats 48 to open the hook grooves 39 on the corresponding sliding sleeves A38 through a series of transmissions. B52 is further compressed. The cable roller is rolled out between the two beam arms A1, the roller shaft breaks away from the hook groove 39 on the sliding sleeve A38, and then, under the action of removing the driving lever 51, the driving block 50 drives the sliding seat 48 under the reset action of the spring B52 The baffle plate 49 resets relative to the sliding sleeve A38 again.

In summary, the beneficial effects of the present invention are: the present invention can adjust the center of gravity position of the cable roller installed on the sliding sleeve A38 of the bracket 24 through the sliding of the beam arm C17 on the beam arm A1 and the beam arm B4, so that The moment arm between the center of gravity of the cable roller installed on the present invention and the axle of rear wheel 3 can not be reduced, makes the center of gravity of cable roller mostly fall on two rear wheels 3 and be positioned at rear wheel 3 and universal wheel all the time 7, without causing the present invention to turn over due to bumps during the uphill process.
