Abstract
The invention discloses a shield tail sealing device for a shield machine. The shield tail sealing device comprises a plurality of shield tail brushes arranged on a shield tail, a steel plate brush which is arranged on the shield tail and is positioned behind the shield tail brushes, and a sealing plate which is arranged on the shield tail and is positioned between two adjacent shield tail brushes at the last end; one end of the sealing plate is connected with the shield tail in a rotatable way, and the other end of the sealing plate is clamped on the shield tail in a detachable way; and an air bag which can be inflated, and pushes the sealing plate to ensure that the sealing plate is separated from the position where the shield tail is clamped with the sealing plate, and is pressed against a pipe piece tightly. Due to the adoption of the technical scheme, compared with the prior art, the shield tail sealing device for the shield machine has the advantages that the shield tail sealing device is provided with the shield tail brushes and the sealing plate, and the air bah can push the sealing plate out to be pressed against the pipe piece, so the sealing effect is achieved.
Description
Technical field
The present invention relates to a kind of tail sealing device of shield of shield machine.
Background technology
The shield tunnel development machine is called for short shield machine, is a kind of special engineering machinery of tunnel piercing.The shield ventral brush often is applied to weak soil layer constructing tunnel, it is an important accessory in the Suporting structure, the gap that it utilizes steel wire to play the bent fluffy formation in back a certain amount of high-quality filler that reinjects plays good sealing function between shield structure and section of jurisdiction, place underground water, outer soil, the slip casting of the lining cutting back side etc. and flow into the tunnel, guarantee tunnel piercing safety, engineering can be carried out smoothly.Tail sealing device of shield of the prior art is made up of with the steel plate brush three road shield ventral brushes, three road shield ventral brushes form two grease cabins, and the shield machine shield tail spillage situation of leaking is quite general, in work progress, it is higher to repair or change shield ventral brush cost, and influences construction speed.In engineering in the past, at shield tail spillage, attempted multiple different counter-measure, often can't reach ideal effect, influenced normally carrying out of shield-tunneling construction.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of tail sealing device of shield of shield machine.
In order to reach above purpose, the technical solution used in the present invention is: the tail sealing device of shield of shield machine, it comprises the multiple tracks shield ventral brush that is arranged on the shield tail, be arranged on the shield tail and at the steel plate brush at shield ventral brush rear, be arranged on the shield tail and the sealing plate between the adjacent shield ventral brush of rearmost end twice, one end of sealing plate is connected rotationally with the shield tail, the other end is connected on the shield tail separatably, is provided with can inflate and promote sealing plate and the access section of sealing plate and shield tail is separated and pushes against air bag on the section of jurisdiction between shield tail and sealing plate.
Further, the tail sealing device of shield of shield machine, it also comprises the air compressor that is connected with air bag.
Preferably, the shield tail is provided with pressing plate, and the other end of sealing plate is connected between pressing plate and the shield tail separatably.
Further, the shield tail is provided with the grease ascending pipe, offers a plurality of grease inlets on the grease ascending pipe, and per pass shield ventral brush is arranged on described facing mutually between two grease inlets.
Further, the shield ventral brush is provided with four roads.
Owing to adopted technique scheme, the tail sealing device of shield of shield machine of the present invention has compared with prior art increased by one shield ventral brush and sealing plate, and air bag can eject sealing plate and push against on the section of jurisdiction, has reached the effect of sealing.
