The hydraulic motor 8 drives the first clamping block 12 to rotate, and further drives the shifting claw 13 to shift the wire coil 14 to rotate, so that the paying-off operation is carried out. The rotating speed of the hydraulic motor 8 can be controlled by the flow of the hydraulic oil flowing through the hydraulic motor, and the hydraulic motor is convenient to control and stable in rotation. The hydraulic drive brake mechanism is adopted to ensure that the wire barrow is more reliable in braking, the braking force can be controlled by the applied hydraulic oil pressure, and the control is convenient. The hydraulic motor 8 and the brake mechanism can control the wire releasing speed, so that the wire is prevented from jumping out of the pulley to swing due to too fast release of the wire, or the arc of the wire is too large, the wire is prevented from colliding with operators or vehicles passing by the road, and safety accidents are avoided.

Be equipped with bull stick 27 between first supporting seat 7 and the second supporting seat 17 bottom, first supporting seat 7 and second supporting seat 17 all with bull stick 27 fixed connection, bull stick 27 rotates with chassis 4 to be connected. First clamp tight piece 12 rotates with first supporting seat 17 to be connected, clamping mechanism is the tight pneumatic cylinder 19 of clamp that sets up in the second supporting seat 17 outside, press from both sides tight pneumatic cylinder 19's cylinder body and second supporting seat 17 fixed connection, press from both sides tight pneumatic cylinder 19's push rod and second supporting seat 17 sliding fit, the tight piece 16 of second clamp rotates with this push rod to be connected, first supporting seat 7 one side is equipped with and is used for driving its pivoted first lifting hydraulic cylinder 5, second supporting seat 17 one side is equipped with and is used for driving its pivoted second lifting hydraulic cylinder 21, under the effect of first lifting hydraulic cylinder 5 and second lifting hydraulic cylinder 21, first supporting seat 7 and second supporting seat 17 rotate along the same rotation in step.

The wire coil 14 is placed on the chassis 4, then the first clamping block 12 and the second clamping block 16 clamp the wire coil 14, and then under the synchronous action of the first lifting hydraulic cylinder 5 and the second lifting hydraulic cylinder 21, the wire coil 14 is lifted, so that the rim of the wire coil 14 is separated from the chassis 4, the wire coil 14 does not need to be lifted manually or hoisting equipment does not need to be used, and the labor intensity is reduced or the use cost of the hoisting equipment is reduced.

The wheel hub inboard of wheel 1 all is through the commentaries on classics board 2 of bolt fixedly connected with rectangle, change 2 upper portions of board and all rotate with chassis 4 and be connected, the inboard of changeing board 2 all is equipped with the pneumatic cylinder 3 that falls of slope, the cylinder body of the pneumatic cylinder 3 that falls all is articulated with chassis 4, the push rod of the pneumatic cylinder 3 that falls is articulated with the commentaries on classics board 2 lower part that corresponds respectively.

Under the effect of hydraulic cylinder 3 of lying, four wheels 1 are all packed up inwards, make 1 pads of wheel under chassis 4, and chassis 4 is pressed on the wheel hub of wheel 1 to it is more stable when the operation to make the wire barrow. In order to further improve the stability, ground anchors can be arranged around the wire barrow and tightened through a steel wire rope.

A hydraulic station 24 and a diesel engine 23 for providing power for the hydraulic station 24 are fixedly arranged on the chassis 4.
