Abstract
The utility model discloses a shield tail brush for a shield machine, including firm piece of preceding elasticity and back elastic steel sheet, it has wrapped up in spring steel wire to press from both sides between preceding elastic steel sheet and the back elastic steel sheet, preceding elastic steel sheet fixes in shield ventral brush skeleton steel sheet with back elastic steel sheet's one end, preceding elastic steel sheet and back elastic steel sheet's the other end is equipped with preceding elastic steel sheet and the backfolding elastic steel sheet who takes the dog -ear respectively. The utility model discloses a preceding elastic steel sheet and backfolding elastic steel sheet be during with the extrusion of concrete lining section of jurisdiction, and preceding elastic steel sheet and backfolding elastic steel sheet fall " S " shape with chenging, forms two contact points with the concrete lining section of jurisdiction, prevent effectively that the mud sediment from getting into the oil pocket in, the grease forms the grease sealing ring of hugging closely the concrete lining section of jurisdiction down in its effect in the oil pocket, in coordination with wholly sealing to reached good sealed effect, can guarantee that the shield constructs going on smoothly of machine tunnelling.
Description
Technical field
The utility model belongs to shield machine technical field, is specifically related to a kind of shield machine shield ventral brush.
Background technology
Shield ventral brush is a kind of sealing device being welded in shield machine afterbody, by wire brush, being used in combination of grease, reaches the purpose of sealing during driving, only slurry.But, original shield ventral brush the most often occurs poorly sealed, and elastic wire is easy to fall off, be easily generated situation about being plastically deformed, and directly affects construction quality and driving process.
Utility model content
The purpose of this utility model is to solve technical problem present in prior art, it is provided that a kind of can be greatly improved tail sealing effect, ensure that shield machine tunnels the shield machine shield ventral brush being smoothed out.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of shield machine shield ventral brush, including front elastic tablet and rear elastic steel sheet, flexible steel wire is wrapped between described front elastic steel sheet and rear elastic steel sheet, one end of described front elastic steel sheet and rear elastic steel sheet is fixed in shield ventral brush skeleton steel plate, and the other end of described front elastic steel sheet and rear elastic steel sheet is respectively equipped with the front folding elastic steel sheet of band knuckle and rear folding elastic steel sheet.
Further, the described front elastic steel sheet knuckle with rear folding elastic steel sheet of rolling over is towards identical.
Further, one end of described front elastic steel sheet and rear elastic steel sheet is fixed in shield ventral brush skeleton steel plate by rivet.
The utility model hinge structure has the advantages that shield machine shield ventral brush of the present utility model is respectively equipped with the front folding elastic steel sheet of band knuckle and rear folding elastic steel sheet on front elastic steel sheet and rear elastic steel sheet, when front folding elastic steel sheet and rear folding elastic steel sheet extrude with concrete lining pipe piece, front folding elastic steel sheet becomes, with rear folding elastic steel sheet, the shape of falling serpentine, two contact points are formed with concrete lining pipe piece, effectively prevent body refuse from entering in oil pocket, grease forms the grease seal ring being close to concrete lining pipe piece under it acts in oil pocket, collaborative integral sealing, thus reached good sealing effectiveness, can guarantee that what shield machine tunneled is smoothed out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state diagram of the present utility model.
The utility model reference implication is as follows: 1, rivet；2, shield ventral brush skeleton steel plate；3, elastic wire；4, front elastic steel sheet；5, rear elastic steel sheet；6, front folding elastic steel sheet；7, elastic steel sheet is rolled over afterwards；8, shield shell；9, grease；10, concrete lining pipe piece.
Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of shield machine shield ventral brush, including front elastic tablet 4 and rear elastic steel sheet 5, flexible steel wire 3 is wrapped between front elastic steel sheet 4 and rear elastic steel sheet 5, one end of front elastic steel sheet 4 and rear elastic steel sheet 5 is fixed in shield ventral brush skeleton steel plate 2 by rivet 1, the other end of front elastic steel sheet 4 and rear elastic steel sheet 5 is respectively equipped with the knuckle of the front folding elastic steel sheet 6 of band knuckle and rear folding elastic steel sheet 7, front folding elastic steel sheet 6 and rear folding elastic steel sheet 7 towards identical.
As shown in Figure 2, in use, 3 road shield machine shield ventral brushes are fixed on shield shell 8, shield machine shield ventral brush is close on concrete lining pipe piece 10, when front folding elastic steel sheet 6 and rear folding elastic steel sheet 7 extrude with concrete lining pipe piece 10, front folding elastic steel sheet 6 becomes, with rear folding elastic steel sheet 7, the shape of falling serpentine, two contact points are formed with concrete lining pipe piece 10, effectively prevent body refuse from entering in oil pocket, grease 9 forms the grease seal ring being close to concrete lining pipe piece 10 under it acts in oil pocket, thus has reached good sealing effectiveness.
