Abstract
The utility model discloses a tail sealing device of a shielding machine. The device comprises multiple tail brushes arranged on the tail, a steel plate brush which is arranged on the tail and positioned on the rear part of the tail brush, and a sealing plate which is arranged on the tail and positioned between two adjacent tail brushes at the rearmost end, wherein one end of the sealing plate is rotatably connected with the tail; the other end of the sealing plate is detachably clamped on the tail; and an air bag which is capable of inflating air, pushes the sealing plate to separate from the clamping place of the tail, and props the sealing plate against a duct piece is arranged between the tail and the sealing plate. In comparison with the prior art, a tail brush and a sealing plate are increased, and an air bag can push and prop against the sealing plate on a duct piece, so that the sealing effect is achieved.
Description
Technical field
the utility model relates to a kind of tail sealing device of shield of shield machine.

The utility model content
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.
are in order to reach above purpose; The technical scheme that the present invention adopts 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 with the shield tail rotationally; The other end is connected on the shield tail separatably, between shield tail and sealing plate, is provided with can inflate and promote sealing plate and the access section of sealing plate and shield tail is separated and pushes against the air bag on the section of jurisdiction.
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, and 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.
