Abstract
The utility model discloses an inclined shield tail brush of a shielding machine, and the inclined shield tail brush comprises a frame body and a multilayer steel wire bundle. An upper elastic steel sheet is arranged at the upper end of the multilayer steel wire bundle, a lower elastic steel sheet is arranged at the lower end of the multilayer steel wire bundle, the upper steel sheet and the lower steel sheet are fixed in the frame body through a pin shaft, and the multilayer steel wire bundle and the shielding machine are arranged to form a corresponding angle in a linear direction. The multilayer steel wire bundle is of four layers of steel wire bundles, two steel wire bundles at the upper layer form a first inclined tail brush, and two steel wire bundles at the lower layer form a second inclined tail brush. The first inclined tail brush and the second inclined tail brush are arranged in the frame body in a staggering manner. According to the inclined shield tail brush of the shielding machine, disclosed by the utility model, the elastic steel sheets are additionally arranged at the upper end and lower end of the multilayer steel wire bundle so that a middle steel wire bundle is clamped and protected by the elastic steel sheets in a working process, and the adhesion of the inclined shield tail brush and the shielding machine is close and is not easy to form fracture of wire; in addition, the multilayer steel wire bundle and the shielding machine are arranged to form a corresponding angle in the direction of an axis so that the steel wire bundle is used for sealing a sealing slot between adjacent tail brushes; and the first inclined tail brush and the second inclined tail brush are arranged in the frame body in a staggering manner, thus the sealing area is increased and the sealing effect is improved.
Description
Technical field
The utility model relates to a kind of shield machine shield ventral brush, relates in particular to the oblique shield ventral brush of a kind of shield machine.
Background technology
Shield machine is mainly used in the constructing tunnel.Shield machine is in tunneling process; The section of jurisdiction is actionless, and the shield body moves continuously, so shield tail and existence slip relatively between the tubulature sheet; Will cause the sewage and the silt of shield external to get into shield structure inside like this, can cause unnecessary wearing and tearing shield machine inside.Inner in order to prevent that outside sewage and silt from getting into the shield structure, just need be to carrying out encapsulation process between shield tail and the section of jurisdiction.At present; The sealing of common shield tail is to be employed in three road ventral brush rings are installed on the shield tail inwall are sealed; And per pass ventral brush ring all is the ventral brush of arranging at 0 ° of angle by a plurality of and shield machine axis and forms, though so play certain sealing function, in practice of construction, exists the shortcoming of fitting closely, be prone to fracture of wire with shield machine; Simultaneously exist certain seal clearance between adjacent two ventral brushes on the per pass ventral brush ring, thereby make sealing effectiveness undesirable.So ventral brush needs often to repair and change, cost is higher, and influences construction speed.
The utility model content
The purpose of the utility model is to provide a kind of shield machine oblique shield ventral brush, and it has solved in the ventral brush prior art and to have fitted closely, be prone to fracture of wire and have shortcoming such as seal clearance, has guaranteed the structural strength of ventral brush, has improved sealing effectiveness.
The purpose of the utility model is to realize through following technical scheme:
The oblique shield ventral brush of a kind of shield machine; Comprise support body and composite steel tow, said composite steel tow upper ends has last elastic steel sheet, and the lower end is placed with down elastic steel sheet; And be fixed on together in the support body through bearing pin, said composite steel tow all is respective angles with the shield machine axis direction and arranges and install.
Further, said composite steel tow is four layers, and upper strata two steel tendons are formed the first oblique ventral brush, lower floor's two steel tendons composition, second oblique ventral brush.
Further, the said first oblique ventral brush and the second oblique ventral brush are staggeredly arranged in support body.
The oblique shield ventral brush of the described shield machine of the utility model, it is through up and down increasing elastic steel sheet in two ends at the composite steel tow, and elastic steel sheet clamps and protects the steel tendon of centre when realizing work, has guaranteed to fit closely, be difficult for shield machine fracture of wire; Adopt the composite steel tow all to be respective angles and arrange installation, make steel tendon seal, promoted sealing effectiveness the sealing off gap between adjacent ventral brush with the shield machine axis direction; Be staggeredly arranged in support body through the first oblique ventral brush and the second oblique ventral brush, increased the area of sealing, further promoted sealing effectiveness.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the oblique shield ventral brush of the said shield machine of the utility model;
Fig. 2 is that A among Fig. 1 is to view;
Fig. 3 is the vertical view of the oblique shield ventral brush of the said shield machine of the utility model.
Among the figure:
1, support body, 2, steel tendon, 3, go up elastic steel sheet, 4, elastic steel sheet down, 5, bearing pin, 6, the first oblique ventral brush, 7, the second oblique ventral brush.
The specific embodiment
Shown in Fig. 1-3; In present embodiment, the oblique shield ventral brush of said shield machine comprises support body 1 and composite steel tow 2; Said composite steel tow 2 upper ends have last elastic steel sheet 3; The lower end is placed with down elastic steel sheet 4, and is fixed on together in the support body 1 through bearing pin 5, and said composite steel tow 2 all is respective angles with the shield machine axis direction and arranges installation.Concrete, composite steel tow 2 is four layers, and upper strata two steel tendons 2 are formed the first oblique ventral brush 6, lower floor's two steel tendons, 2 compositions, second oblique ventral brush 7.The said first oblique ventral brush 6 and the second oblique ventral brush 7 are staggeredly arranged in support body 1.
During work, section of jurisdiction and shield tail produce relatively and slide, last elastic steel sheet 3 downwarpings; Compress steel tendon 2; Make that elastic steel sheet 4 closely contacts with the section of jurisdiction extrados with steel tendon 2 all the time down, go up elastic steel sheet 3 simultaneously and step up steel tendon 2, improve sealing effectiveness and protect steel tendon 2 with following elastic steel sheet 4; Steel tendon 2 all is respective angles with the shield machine axis direction and arranges installation, makes steel tendon 2 cover the sealing off gap between adjacent ventral brush.
The oblique shield ventral brush of said shield machine, it has solved in the ventral brush prior art and to have fitted closely, be prone to fracture of wire and have shortcoming such as seal clearance, has guaranteed the structural strength of ventral brush, has improved sealing effectiveness.
