By applying the technical scheme of the embodiment, during lining construction, the gantry jack, the split heads type support and the traversing mechanism are supported and stressed, the travelling mechanism is suspended, and then the gantry jack screw rod is screwed out to ensure that the split heads type support at the lower part of the gantry jack screw rod (the support and the gantry jack are rotatably, detachably and movably connected) is firmly supported with the bottom surface; when the gantry crane needs to enter a walking state, the gantry jack screw rod is rotated back to ensure that the split heads at the lower part of the gantry jack screw rod are lifted off the ground in a suspended mode and are higher than the bottom surface of the walking mechanism, then the jacking oil cylinder is retracted until the walking mechanism gradually contacts with the track, and the base is moved transversely and is suspended on the ground. Because of possible unevenness of the ground and the integral error of the trolley, the walking mechanisms are designed to be hinged in order to ensure good contact and stress between the walking wheels of the walking mechanisms and the track in the walking process of the trolley. However, the running mechanism is of a non-completely symmetrical structure, and the eccentric force under the dead weight easily causes the running mechanism at the lower part to rotate along the hinged shaft, so that the running mechanism is easily collided with the bottom of the longitudinal beam of the portal frame or the running wheels are not contacted with the track at the same time when the portal frame is jacked up and retracted. In order to ensure the proper swing of the travelling mechanism, a limiting device is arranged between the lower hinged seat and the upper hinged seat, so that the travelling mechanism can swing within a small range and can be prevented from tipping over due to the unbalance. The split heads are structurally arranged so that portal jacks are not directly pressed on the top surface of the track, the contact area with the ground is increased, and the force is effectively transmitted to the ground during lining construction; the width and height of the middle hole are larger than those of the rails, so that enough clearance between the rails and the rails is ensured, and when the walking wheels are not in contact with the top surfaces of the rails, the whole section of rails can be directly dragged forwards to the next construction station without disassembling the rails section by section and then transferring.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
