Shield ventral brush is the parts preventing shield machine afterbody from infiltrating muddy water, and generally have steel plate brush and wire brush two kinds, steel plate brush mainly plays the function preventing block from entering tunnel.The core component of steel plate brush is spring steel plate, and its structure is the steel plate of bending, and spring steel plate can continuous elastic be fitted at work, then easily expendable distortion is produced, so just can not seal shield machine afterbody well, cause entering of block, bring the shortening in application life.
The utility model is exactly to provide a kind of new shield ventral brush structure to solve above problem.
Utility model content
Main purpose of the present utility model is the shield machine shield ventral brush structure providing a kind of Stability Analysis of Structures, long service life.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of shield machine shield ventral brush structure, comprise around the uniform some shield ventral brush unit of shield machine body tail inner side, the base plate that each described shield ventral brush unit comprises and described shield machine body is fixed, the pressing plate being fixed on described plate outer side by screw element and the multilayer be held between described base plate and pressing plate roll over the elastic steel sheet of shape, adjacent described elastic steel sheet staggers fixing, and adjacent two described shield ventral brush unit are at least connected by one piece of described elastic steel sheet.
Concrete, described screw element is screw and nut.
Concrete, described base plate has the afterbody of outwards bending, and described base plate afterbody welds mutually with pressing plate afterbody.
Concrete, base plate described in every block is provided with at least four base plate fixing holes, and pressing plate described in every block is provided with pressing plate fixing hole the same number of with described base plate fixing hole.
Further, elastic steel sheet described in every block is provided with four steel disc fixing holes.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is:
1, the elastic steel sheet by being crisscross arranged connects adjacent shield ventral brush unit, utilizes the active force between elastic steel sheet to make structure more stable, improves application life;
2, base plate afterbody welds with pressing plate afterbody, and shield ventral brush unit is a firmly entirety, not easily disintegrates.

Numeral in figure:
1-shield ventral brush unit, 11-base plate, 111a, 111b, 111c, 111d-base plate fixing hole, 12-pressing plate, 121a, 121b, 121c, 121d-pressing plate fixing hole, 13-elastic steel sheet, 131a, 131b, 131c, 131d-steel disc fixing hole, 14-bolt, 15-nut; 2-shield machine body.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figures 1 to 5, a kind of shield machine shield ventral brush structure, comprise around the uniform some shield ventral brush unit 1 of shield machine body 2 tail inner side, the base plate 11 that each shield ventral brush unit 1 comprises and shield machine body 2 is fixing, to be fixed on the elastic steel sheet 13 that the pressing plate 12 outside base plate 11 and the multilayer be held between base plate 11 and pressing plate 12 roll over shape by bolt 14 and nut 15, adjacent elastic steel sheet 13 staggers fixing, and two adjacent shield ventral brush unit 1 are at least connected by one piece of elastic steel sheet 13.Thus, except outermost two panels elastic steel sheet 13, middle elastic steel sheet 13 is all subject to the active force of elastic steel sheet to it of both sides, again because the layout of shield ventral brush unit 1 itself is exactly annular connected head-to-tail, therefore this structure is more stable, application life is higher, but structure is simple, and manufacture process is also uncomplicated.
As shown in Figure 2 and Figure 5, base plate 11 has the afterbody (mark) of outwards bending, and base plate 11 afterbody welds mutually with pressing plate 12 afterbody.Each like this shield ventral brush unit 1 is a firmly entirety, self compares at work and is not easy to disintegrate.
As shown in Figures 3 to 6, every block base plate 11 is provided with four base plate fixing holes 111a, 111b, 111c, 111d, every block pressur plate 12 is provided with four pressing plate fixing holes 121a, 121b, 121c, 121d, and every block elastic steel sheet 13 is provided with four steel disc fixing holes 131a, 131b, 131c, 131d.Penetrating screw 14 in each base plate fixing hole 111a, 111b, 111c, 111d when assembling on base plate 11, then finishing up near being welded on shield machine body 2 inwall, when spelling first floor elastic steel sheet 13, steel disc fixing hole 131a, 131b, 131c, the base plate fixing hole 111d that 131d is corresponding in turn to, 111a, 111b, 111c, steel disc fixing hole 131a on second layer elastic steel sheet 13, 131b, 131c, the base plate fixing hole 111a that 131d is corresponding in turn to, 111b, 111c, 111d, steel disc fixing hole 131a on third layer elastic steel sheet 13, 131b, 131c, the base plate fixing hole 111b that 131d is corresponding in turn to, 111c, 111d, 111a, 4th layer of elastic steel sheet 13 is identical with the layout of first floor elastic steel sheet 13, every three layers is a circulation, by that analogy, last four pressing plate fixing holes 121a, 121b, 121c, 121d respectively corresponding four base plate fixing holes 111a, 111b, 111c, 111d pass screw 14, then fix with nut 15, again base plate 11 afterbody is welded with pressing plate 12 afterbody, complete the installation of whole shield ventral brush.
