[specific embodiment]
As shown in Figure 1, 2, 3, a kind of supporting construction of the internal clamp that is adapted to the moisture mud layer of inner-walls of duct, comprise: internal clamp, two walking mechanisms on described internal clamp, comprise: pre-walking mechanism 4, rear walking mechanism 3, the front support mechanism 6 that the front of described pre-walking mechanism 4 arranges is fixed on the head of internal clamp, the rear support mechanism 1 that the front of rear walking mechanism 3 arranges is fixed on the afterbody of internal clamp, and wherein front support mechanism 6 has the locking guiding mechanism of adjusting with rear support mechanism 1 spacing.
Described front support mechanism 6, comprising: bracing frame 6.5, support wheel, and support frame as described above upper end is fixedly connected on the gas tank 6.19 of internal clamp head by clamping screw 6.1, locking nut 6.2; Support frame as described above 6.5 lower ends are fixed by wheel shaft and support wheel; Support wheel by bearing 6.11, bearing outside 6.15, bearing holder (housing, cover) 6.16, bearing gland 6.8, bearing pin 6.9, bearing nut 6.10 and connect to form with foreign steamer 6.17.
Described rear support mechanism 1 comprises: bracing frame 1.5, support wheel, and support frame as described above upper end is fixedly connected on the gas tank 1.19 of internal clamp head by clamping screw 1.1, locking nut 1.2; Support frame as described above 1.5 lower ends are fixed by wheel shaft and support wheel; Support wheel by bearing 1.11, bearing outside 1.15, bearing holder (housing, cover) 1.16, bearing gland 1.8, bearing pin 1.9, bearing nut 1.10 and connect to form with foreign steamer 1.17.

For a method for supporting for inner-walls of duct lining internal clamp, its step is as follows:
1, when the docking welding of two pipe ports is complete, in the time of need to carrying out the docking welding of next two pipe ports, start pre-walking mechanism 4 and the rear walking mechanism 3 of the internal clamp of the moisture mud layer of inner-walls of duct, internal clamp moves ahead;
2, when the pre-walking mechanism 4 of internal clamp runs into while there is no the port of concrete lining docking weld bond position, the front support mechanism 6 of internal clamp head, has been supported on inner-walls of duct lining, and the rear walking mechanism 3 of internal clamp drives internal clamp to move ahead;
3, when the rear walking mechanism 3 of internal clamp runs into while there is no the port of concrete lining docking weld bond position, the rear support mechanism 1 at internal clamp rear portion, is still supported on inner-walls of duct lining, and the pre-walking mechanism 4 of internal clamp drives internal clamp to move ahead;
4, final, rear support mechanism 1 crosses over does not have the port of concrete lining docking weld bond position, thereby makes internal clamp smoothly by there is no the weld bond position of concrete lining.
Due in pipeline or not with concrete lining in weld bond position, have a segment distance there is no lining, so after welding completes internal clamp when walking, pre-walking mechanism and rear walking mechanism can be absorbed in the position that there is no concrete lining.The present invention has increased to support and has adjusted and retaining mechanism, increases after front support mechanism and rear support mechanism, when pre-walking mechanism moves to weld bond position, because the support of front support mechanism and rear walking mechanism has been avoided front walking wheel and is absorbed in position, Hankow; When rear walking mechanism moves to position, Hankow, because the support of pre-walking mechanism and rear support mechanism has been avoided equally rear walking wheel and is absorbed in position, Hankow, thereby make mouthpart smoothly by there is no the weld bond position of concrete lining.Before and after can guaranteeing, walking mechanism, smoothly by weld bond position, has effectively been eliminated the error that concrete lining thickness exists.
