Abstract

The utility model relates to a driving device designed for driving underground pipelines, which is characterized in that the entire device is composed of a cavity type drill bit of which the cavity is arranged inside with a spiral conveyor, a ratchet plate type bulk material conveying chain arranged behind the spiral conveyor in the drilling machine, and an oil feeding cylinder arranged on a mopping board box frame behind the chain. The cavity type drill bit and the spiral conveyor are driven by a motor and a transmission device in the drilling machine, and the ratchet plate type bulk material conveying chain is driven by a swinging drive wheel for reciprocating movement to convey soil. The utility model has compact structure, high efficiency and low cost, and the utility model can simultaneously accomplish digging holes, conveying soil, driving work and continuous work.

Description

A kind of underground pipeline road heading machinery

The utility model relates to engineering machinery, particularly a kind of underground pipeline mole.

Existing underground pipeline construction adopts mostly and excavates the operation of formula groove, and the earthwork amount is big, worker's post processing difficulty before the worker, and influence surface structures and traffic.For overcoming this drawback, the implementation of existing construction by pipeline jacking method, general construction by pipeline jacking method, though excavating earth surface no longer, but earthwork is still many with manually finishing in the pipe, operation inconvenience, labour intensity are greatly, work efficiency is also low.And the SH of Japanese Design series rig and the follow-on horizontal jacking pipe spiral drilling machine of China all adopt spiral to fail native device, and type is huge, cost is high, are difficult for popularizing using.

The purpose of this utility model provides a kind of in underground soil layer, can finish simultaneously to dig a hole, fail soil, jacking operation, the road heading machinery of excavating underground pipe line continuously.

For the earth drill structure of finishing the underground pipeline road heading machinery that the invention task designs, defeated native mechanism and jacking mechanism fuse, the earth drill structure by the bore cavate drill bit identical with the pipeline aperture, in the cavate drill bit helical conveyor and place motor, reductor and gear pair in the rig body to form together; The sour jujube plate bulk cargo of defeated native mechanism carries the horizontal fixed pulley of chain cable front end to place under the rig body inside spin conveyer rear end, the board-like bulk cargo conveying of sour jujube chain cable rear end around waving on the driving wheel, is waved driving wheel and is linked to each other with motor with crank connecting link through pull bar behind two vertical fixed pulleys; Jacking mechanism is the jacking oil cylinder on the planker balladeur train of rig body rear portion.

In order to control tunneling direction, the rig body of the utility model underground pipeline mole is provided with directed wing plate and the tuning wing plate that links to each other with controller.

Embodiment describes the utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model underground pipeline mole schematic diagram.

As shown in Figure 1, the motor 9 that is arranged in the rig body 3 drives cavate drill bit 1 through reducer 8 and gear pair 5, earth under the drilling etc. enters and bores the chamber, being pushed to the board-like bulk cargo of sour jujube by helical conveyor 2 carries on the chain cable 7, the board-like bulk cargo of sour jujube carries the horizontal fixed pulley 6 of chain cable 7 front ends to be arranged under helical conveyor 3 rear ends, the board-like bulk cargo of sour jujube carry chain cable 7 rear ends behind two vertical fixed pulleys 12 around waving on the driving wheel 14, wave driving wheel 14 through pull bar 13 with link to each other with motor 8 by handle connecting rod 17, earth etc. can be transported in the operating mechanism hole.Jacking oil cylinder 16 on the planker balladeur train 15 withstands on the working pit inwall.Directed wing plate 4 and the tuning wing plate 11 that links to each other with controller 10 are arranged on the rig body 3.

This machine compact conformation can be finished simultaneously the digging a hole of underground pipeline, defeated soil, jacking operation, continuous operation automatically, and the efficient height assists recruitment few, and cost is low.

Claims

1, a kind of underground pipeline road heading machinery, form by earth drill structure and defeated native mechanism, it is characterized in that said earth drill structure, defeated native mechanism and jacking mechanism fuse, the earth drill structure by the bore cavate drill bit identical with the pipeline aperture, in the cavate drill bit helical conveyor and place motor, reductor and gear pair in the rig body to form together; The sour jujube plate bulk cargo of defeated native mechanism carries the horizontal fixed pulley of chain cable front end to place under the rig body inside spin conveyer rear end, the board-like bulk cargo conveying of sour jujube chain cable rear end around waving on the driving wheel, is waved driving wheel and is linked to each other with motor with crank connecting link via pull bar behind two vertical fixed pulleys; Jacking mechanism is the jacking oil cylinder on the planker tank tower of rig body rear portion.
