Abstract
The present invention relates to a pipe jacking bearing vehicle which is characterized in that the pipe jacking bearing vehicle comprises a left supporting leg (1) with rollers, a right supporting leg (1) with rollers and an upper cross beam (5), wherein the upper cross beam (5) can be combined with the left supporting leg and the right supporting leg by an elevating mechanism; the middle part of the upper cross beam (5) is in a concave arc structure. Compared with the prior art, the present invention has the advantages of reasonable structure, safe and convenient operation, and high production efficiency; the present invention can conveniently adjust the angle between every two butting pipelines and precisely butt two pipelines on the premise that the anticorrosive layer outside the pipeline is not damaged.
Description
Technical field
The present invention relates to underground pipeline construction equipment, relate to a kind of specifically and the matching used pipe-jacking bearing truck of pipe jacking equipment.
Background technique
Along with the continuous development of under ground piping non-excavation laying construction technology, one of the most common method of construction when pipe-jacking technology has become pipeline and passes through ground obstacle.In existing pipe-jacking technology construction, be mostly the mode that employing track support slides for the conveying for the treatment of the push pipe road.The existing problem of this mode of movement is: 1, owing to treat to be the slippage fit system between push pipe road and the conveyor track, exist great frictional force between the two in course of conveying, very easily will treat the anticorrosive coat destruction that applies in advance on the push pipe pipeline outer wall; 2,, be difficult to realize the precision butt joint between two pipelines because the height of conveyance conduit can't be regulated by conveyor track, and the counterpart angle between two pipelines has only the mode of lifting by artificial sled to adjust.
Summary of the invention
Purpose of the present invention provides a kind of adjustable pipe-jacking bearing truck rational in infrastructure, easy to manufacture, safe and convenient to use at existing deficiency in the above-mentioned prior art just.
Purpose of the present invention can realize by following measure:
Pipe-jacking bearing truck of the present invention comprises the left and right sides supporting leg that has roller, and the upper beam that combines with left and right sides supporting leg by elevator mechanism; The middle part of described upper beam is the concave arc shape structure.
Left and right sides supporting leg among the present invention can be made up of supporting leg pedestal, the roller that is installed in the supporting leg base bottom, the screw type guide upright post that is arranged on supporting leg pedestal top; On the screw type guide upright post, adjusting nut and guide sleeve are installed from bottom to top successively, described upper beam combines with guide sleeve by the axis hole that its two ends process, and in the bottom of guide sleeve thrust-bearing is installed; Match with the end face of adjusting nut in the Xia Quan bottom surface of described thrust-bearing, end face of circle matches with the bottom surface of upper beam axis hole on it.
Working principle of the present invention is as follows:
Cushion cap car of the present invention is placed on the guide rail that lays in advance, to treat that again the push pipe road is transferred to upper beam, mobile afterwards cushion cap car, and by the adjusting to elevator mechanism realize treating the push pipe road and the counterpart angle between the jacking pipeline adjust, and then realize precision butt joint between two pipeline opening.
The present invention not only has rational in infrastructure, safe and convenient to use, advantage of high production efficiency compared to existing technology, the present invention that main is can be under the prerequisite that avoids making the pipeline external anti-corrosion layer to be destroyed, realize adjustment easily, realize the precision butt joint between two pipelines counterpart angle between the butt joint pipeline.

Fig. 2 is that the A of upper beam among Fig. 1 is to view.
Fig. 3 is the partial enlarged drawing of supporting leg part among Fig. 1.
Embodiment
The present invention is further described below with reference to embodiment's (accompanying drawing):
As shown in Figure 1, 2, pipe-jacking bearing truck of the present invention comprises the left and right sides supporting leg that has roller 6, and the upper beam 5 that combines with left and right sides supporting leg by elevator mechanism; The middle part of described upper beam 5 is and the concave arc shape structure for the treatment of that push pipe road periphery matches; Described left and right sides supporting leg all is made up of supporting leg pedestal 1, the roller 6 that is installed in supporting leg pedestal 1 bottom, the screw type guide upright post 4 that is arranged on supporting leg pedestal 1 top; On screw type guide upright post 4, adjusting nut 2 and guide sleeve 3 are installed from bottom to top successively, described upper beam 5 combines with guide sleeve 3 by the axis hole that its two ends process, and in the bottom of guide sleeve 3 thrust-bearing 7 is installed; Match with the end face of adjusting nut 2 in the Xia Quan bottom surface of described thrust-bearing 7, end face of circle matches with the bottom surface of upper beam 5 axis holes on it.
