The first driving wheel 11, the first tensioning wheel 14, the first driven wheel 12, the second driving wheel 21, the second driven wheel 22 and the second chain 23 are all arranged on a rack. Either the traction motor or the rack is shown in the FIG, which is a conventional technique in the art and no more details are stated herein.
The second pushing plate 25 in the present embodiment has a clamping driving device 4 connected, the clamping driving device 4 is applied to driving the pushing plate to move in a radial direction; the clamping driving device 4 is a hydraulic cylinder.
The first pushing plates 15 and the second pushing plate 25 are applied to constructing a conduit guiding channel between a certain number of the clamping blocks 3 on the first chain 13 and a certain number of the clamping blocks 3 on the second chain 23, and making the certain number of the clamping blocks 3 on the first chain 13 and the second chain 23 clamp the conduit 7.

A working principle of the present application is as follows:
a free end of the conduit 7 passes through between the clamping blocks 3 on the first chain 13 and the second chain 23;
the first pushing plate 15 and the second pushing plate 25 press the clamping blocks 3 on the first chain 13 and the second chain 23, so that the clamping blocks 3 clamp the conduit 7;
the first driving wheel 11 and the second driving wheel 21 rotate to drive the first chain 13 and the second chain 23 to move, and then drive the clamping block 3 to move, so that the conduit 7 clamped by the clamping blocks 3 moves downwards a well or upwards a lifting direction.
