Abstract

The utility model relates to a combined type horizontal pipeline propelling device with two rails, which mainly comprises a guide rail, a drilling hole power scaffold installed on the rail, a hydraulic propelling mechanism and a control part, wherein the guide rail is formed by assembling a plurality of bar frames with two rails. Every section of rail frame is provided with a pair of sliding rails and a pair of tooth-shaped propelling rails. The drilling hole power scaffold is arranged on the sliding rails on the rail frames by rollers arranged at the two sides of the drilling hole power scaffold. A hydraulic cylinder of the hydraulic propelling mechanism is arranged on the tooth-shaped propelling rails by the supporting frames arranged at the two ends of the hydraulic cylinder. The propelling device can directly push the pipelines to pass through the ground surface under the condition of not damaging roads and buildings.

Description

Combined horizontal pipe propulsion unit with two rails

The utility model is a kind of combined type two-orbit horizontal pipe advancing means, it is a kind of pipelayer attachment that need pass through road, building laying various pipes, cable that is applicable to, it mainly comprises guide track, in orbit boring power stand, hydraulic-feed mechanism are installed, and the manoeuvre portion composition that grades.

At present, China cities and towns are being passed through road, when building is laid various pipes, are being adopted open drain formula excavation more, or the excavation operation of detouring, and this operating type not only workload is big, but also brings certain destruction can for road or building.It is that the pipe laying hole is passed through in a kind of boring of 90207970.0 that Chinese patent CN2121597 U discloses the patent No., and its major technique feature is: by the boring part that is used to hole, the power section and the operation control section that are used to supply with boring power are formed.Though above-mentioned patented technology has solved the earth drilling problem of passing through road, also need manually pipeline to be headed into.

The purpose of this utility model provides a kind of boring, push pipe to finish by a machine with regard to being to overcome above-mentioned deficiency of the prior art, the combined type two-orbit horizontal pipe advancing means that can directly head into for the less pipeline of diameter.

The purpose of this utility model can adopt following measure to realize: the utility model mainly comprises guide track, in orbit boring power stand, hydraulic-feed mechanism are installed, and the manoeuvre portion critical piece that grades is formed, guide track is to be formed by more piece two-orbit frame combination, every joint track-frame all is provided with a pair of sliding rail and a pair of profile of tooth advances track; Boring power stand is placed on the sliding rail on the track-frame by the roller that is arranged on its both sides; The oil hydraulic cylinder of hydraulic-feed mechanism is placed in profile of tooth by the supporting frame that is arranged on its two ends and advances on the track.

Oil hydraulic cylinder front portion in the utility model combines by hinge and front support stand, is connected with a framework that is used to hole power stand location on the front support stand, is processed with a plurality of positioning holes on two regulating arms of framework; The front end of framework is equipped with a baffle plate that has a groove, its rear portion by with framework combine about two rod rests be placed on sliding rail and profile of tooth advances on the track 1; The rear portion of oil hydraulic cylinder is placed on profile of tooth by the back support frame frame hinged with it and advances on the track.Lay at least one U type carriage on the sliding rail of two-orbit framework, a roller respectively is equipped with in the both sides of U type carriage.

Use advancing means of the present utility model to carry out highway crossing, railway, channel, or building can not influence traffic when laying various pipes, not destroy under the situation of building, pipeline is directly being passed by certain depth requirement pushing tow from subsurface.Not only a large amount of labour forces can be saved, and the fund that excavation back road is laid again can be saved.

The drawing of accompanying drawing is described as follows:

Fig. 1: plan view of the present utility model, can be as the specification digest accompanying drawing.

The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):

Advancing means of the present utility model mainly comprises guide track, and in orbit boring power stand, hydraulic-feed mechanism are installed, and the manoeuvre portion critical piece that grades; Guide track of the present utility model is to be formed by more piece two-orbit frame combination, and every joint track-frame all is provided with a pair of sliding rail 2 and a pair of profile of tooth that is provided with equidistant propelling tooth advances track 1; Oil hydraulic cylinder 3 front portions of hydraulic-feed mechanism combine by hinge and front support stand, are connected with a framework 6 that is used to hole power stand 4 location on the front support stand, are processed with a plurality of positioning holes on two regulating arms of framework 6; Two regulating arm front ends of framework combine with the baffle plate 7 that has groove by bearing pin, its rear portion by with framework combine about 8 of two poles be placed on sliding rail 2 and profile of tooth and advance on the track 1; The upper end of pole 8 is placed on the sliding rail 2 by roller mounted thereto, and its lower end is placed on profile of tooth and advances on the track 1; The rear portion of oil hydraulic cylinder 3 is placed on profile of tooth by 9 of the back support frames hinged with it and advances on the track 1.Boring power stand 4 is installed on two regulating arms of framework 6, and is placed on the sliding rail on the track-frame by the roller 5 that is arranged on its both sides; Lay boring on the boring power stand 4 and drive speed reducer and oil hydraulic motor, auger stem is installed on the output shaft of speed reducer.The sliding rail of two-orbit framework is laid the U type carriage 10 that is used for frame trustship road, and a roller respectively is equipped with in the both sides of U type carriage 10, and carriage can move along sliding rail by roller.The usage quantity of carriage 10 can be determined according to the length of pipeline.

When using advancing means of the present utility model to carry out pipe laying, device can be placed in the working pit that excavation is good in advance, length according to working pit, two joints or more piece track-frame are coupled together with bolt, again other parts are installed on the track of framework successively, adjust the levelness of complete machine, after the perpendicularity, pipeline can be hung on U type carriage when small-bore pipeline need not holed (if), according to the thickness of pipe diameter adjustment carriage punch pad, connect power source, make baffle plate 7 withstand the propelling pipeline, hydraulic jack moves reciprocatingly by hydraulicdirectional control valve, during propelling, the oil cylinder piston bar stretches out, and dunnage is advanced a distance that advances tooth, when piston rod shrinks, rear bearing sheet is by the inclined-plane that the advances tooth tooth pitch that advances, and action and so forth is till work finishes.Can start drilling rod boring earlier for the pipeline of larger caliber, and then the primer fluid into mechanism of bearing down on one, pipeline and drilling rod are advanced synchronously.
