Abstract

A pipe-jacking machine with recyclable core components comprises a casing, a cutting tool as well as a main shaft and a power box thereof, tool bars and scratching tools arranged on the tool bars, and a sludge inlet and outlet pipe, wherein the cylinder at the rear section of the taper of the tool and the cylinder at the rear section of the cone of the casing are used for separating the head part of the pipe-jacking machine into a soil bin and a muddy water bin; the soil bin is formed by a conical tool body and the cone of the casing; the conical tool body is placed at the front end of the casing of the pipe-jacking machine; a plurality of groups of tool bars are symmetrically arranged on the conical surface of the conical tool body; the power box of the pipe-jacking machine adopts a flange mode, and is fixed on the casing through a bolt; an output shaft of the power box is connected with the cone of the tool; a tool bar twisting base is welded on the tool shaft sleeve of the cone of the tool, and the tool bar bodies are fixed on the tool bar twisting base through a pin shaft, and can swing on the tool bar twisting base through the pin shaft; the gaps of the tool bar bodies and the cone of the tool are filled with rubber infill for preventing sludge cakes from entering; and the tool bar bodies are fixed on the cone of the tool to prevent the tool bar bodies from being dumped forwards and to enable the whole tool bar bodies to be stressed.

Description

A kind of pipe jacking tunnelling machine of recyclable core component

Technical field

The utility model relates to the push-bench that uses in the trenchless engineering construction in the construction engineering technical field, particularly relates to the manufacturing package technique of push-bench.

Background technique

The present common push-bench phenomenon that in the jacking construction process, can occur getting into a difficult position, as the place that can not excavate at the bottom of construct river bed or the building etc., and push-bench the place ahead runs into unvanquishable obstacle.This moment, push-bench can not advance, and can not retreat, and can not do well again from above and take out push-bench.Often a value push-bench up to a million just can only be stayed the end, ground, lets alone corrosion and rots; The push-bench of placing oneself in the midst of the end, ground also may become the obstacle of Other Engineering in the future.Simultaneously, very good pipeline can not normally use, and has wasted the great amount of manpower and material resources resource, especially loses best construction geographical position.

Summary of the invention

The purpose of this utility model is the existence at the problems referred to above, providing a kind of can transport in the pipeline of having constructed can take measures to make push pipe inboard installation dismounting when jacking construction is in distress after, recover to have constructed the pipe jacking tunnelling machine of recyclable core component of function of use of pipeline, it is suitable for the jacking construction of various soil properties.

For achieving the above object, the technical solution adopted in the utility model is: a kind of pipe jacking tunnelling machine of recyclable core component, comprise housing, cutting cutterhead and main shaft and power box, knife bar and be installed on scraper on the knife bar, housing, advance sludge drainage pipe, wherein cutterhead cone back segment cylindrical body and housing cone back segment cylindrical body are divided into clay bin and muddy water storehouse with the push-bench head part, clay bin is formed by conical cutter head and housing cone, its tapered knife disk body places push-bench housing front end, be arranged with the array knife bar on the conical surface, described in the power box 02 of pipe jacking tunnelling machine adopt form of flanges, by being bolted on the housing 01; The output shaft of power box 02 is connected with cutterhead cone 03; The cutter axis that knife bar twisted seat body 04 is welded on cutterhead cone 03 puts, and knife bar body 06 is fixed on the knife bar twisted seat body 04 by bearing pin 05, and knife bar body 06 can be in 04 swing of knife bar twisted seat body by bearing pin 05; And be filled with the rubber obturator 08 that prevents that clod from entering between the space of knife bar body 06 and cutterhead cone 03, knife bar body 06 is fixed on the cutterhead cone 03, topples over forward to prevent knife bar body 06, makes knife bar body 06 whole stressed.

Working principle of the present utility model and process are: remove the miscellaneous part that has obstruction backward to move when core component reclaims earlier, one section screw of releasing lever bolt is pressed the pull bar bolt forward then, and the knife bar body is toppled over tentatively forward.Remove the connecting bolt of power box and casing, finish the releasing lever bolt and spur the core component assembly backward, the knife bar end slides on the inclined-plane of housing cone, by rotating toward outer incline on the hinge joint seat of bearing pin, last cutterhead assembly integral enters in the casing by the power box attachment hole, decomposes the core component assembly then in casing, and the loose mail piecemeal is transported pipeline, realize reclaiming the core component of pipe jacking tunnelling machine, reach the purpose of this utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Embodiment

As depicted in figs. 1 and 2, the pipe jacking tunnelling machine of a kind of recyclable core component described in the utility model comprises housing, cutting cutterhead and main shaft and power box, knife bar and be installed on scraper on the knife bar, housing, advance sludge drainage pipe, wherein cutterhead cone back segment cylindrical body and housing cone back segment cylindrical body are divided into clay bin and muddy water storehouse with the push-bench head part, clay bin is formed by conical cutter head and housing cone, its tapered knife disk body places push-bench housing front end, be arranged with the array knife bar on the conical surface, the power box 02 of described pipe jacking tunnelling machine adopts form of flanges, by being bolted on the housing 01; The output shaft of power box 02 is connected with cutterhead cone 03; The cutter axis that knife bar twisted seat body 04 is welded on cutterhead cone 03 puts, and knife bar body 06 is fixed on the knife bar twisted seat body 04 by bearing pin 05, and knife bar body 06 can be in 04 swing of knife bar twisted seat body by bearing pin 05; And be filled with the rubber obturator 08 that prevents that clod from entering between the space of knife bar body 06 and cutterhead cone 03, knife bar body 06 is fixed on the cutterhead cone 03, topples over forward to prevent knife bar body 06, makes knife bar body 06 whole stressed.

Working principle of the present utility model and process are: when pipe jacking tunnelling machine reclaims the core component assembly, tear loose stay-bolt 07 earlier open, press the pull bar bolt forward, the knife bar body is toppled over tentatively forward.Remove power box 02 and machine shell 01 adpting flange bolt and stay-bolt 07, make whole core component assembly be in quick condition, drag the core assembly then and in machine, draw.Knife bar body 06 end slides on the inclined-plane of housing cone, and by rotating toward outer incline on the hinge joint seat of bearing pin 05, last core assembly integral enters in the casing by power box 02 and machine shell 01 attachment hole, realizes reclaiming the core component of pipe jacking tunnelling machine.
