Abstract
The utility model discloses a maintenance hole sealing device for a concrete mixing carriervehicle, which comprises an outer tank wall and a maintenance hole cover. A sealing rubber pad is arranged between the outer tank wall and the maintenance hole cover, bolts penetrate through the outer tank wall, the sealing rubber pad and the maintenance hole cover, the outer tank wall, the sealing rubber pad and the maintenance hole cover are pressed by pressing nuts, and flat pads and elastic pads are arranged between the maintenance hole cover and the bolts in sequence. Since arc-shaped edges and middle planes are sealed in sequence when the maintenance hole cover and maintenance holes are pressed, the maintenance hole sealing device has better sealing effect than the ordinary flat rubber pad.
Description
Technical field
The utility model belongs to the sealing technique of transit mixer service hatch, particularly a kind of seal arrangement of concrete mixing and transporting car service hatch.
Background technique
General in the market service hatch seal rubber pad mainly is a plane sealing, when the maintenance port lid is not good the combination with the service hatch edge, will cause poorly sealed closely, cause the interior solvent or diluent of tank body in the transit mixer transportation process to leak outside, not only influence the tank body appearance quality, and pollute the environment.
The model utility content
The purpose of this utility model is to provide a kind of seal arrangement of concrete mixing and transporting car service hatch, after the maintenance port lid compresses, article two, the edge circular arc forms two annulus sealings, in conjunction with middle plane sealing, more effectively the concrete that stirs in the tank body is sealed.
The technical solution that realizes the utility model purpose is: a kind of concrete mixing and transporting car service hatch seal arrangement, comprise tank wall, maintenance port lid, between tank wall and maintenance port lid, seal rubber pad is set, bolt passes tank wall, seal rubber pad and maintenance port lid, compress tank wall, seal rubber pad and maintenance port lid by gland nut, and between maintenance port lid and bolt, set gradually plain cushion, bullet pad.
The utility model compared with prior art, its remarkable advantage: (1) circular arc limit and midplane when compressing maintenance port lid and service hatch successively seals, and sealing effect is more effective much than common flat rubber cushion.(2) can effectively prevent because transit mixer keeps in repair the uneven situation that causes poorly sealed leakage material between port lid and the tank body.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is that the situation schematic representation is joined in the assembling of one in the assembling of concrete mixing and transporting car service hatch seal arrangement.
Fig. 2 is the plan view of seal rubber pad, and expression sealing rubber cushion is a round structure, uniform bolt hole on it.
Fig. 3 is the cross sectional view of Fig. 2, has represented the cross section structure of sealing gasket.
Embodiment
In conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model concrete mixing and transporting car service hatch seal arrangement, comprise tank wall 2, maintenance port lid 7, between tank wall 2 and maintenance port lid 7, seal rubber pad 3 is set, bolt 5 passes tank wall 2, seal rubber pad 3 and maintenance port lid 7, compress tank wall 2, seal rubber pad 3 and maintenance port lid 7 by gland nut 1, and between maintenance port lid 7 and bolt 5, set gradually plain cushion 4, bullet pad 6.Wherein seal rubber pad 3 is the sealing rubber ring on big small circle gridle circular arc limit, is made of big or small circular arc limit and middle plane, on the center line between the seal rubber pad 3 big small circle ring limits bolt hole is set evenly.Utilize two circular arc limits and midplane that the object junction plane is effectively sealed like this, can effectively seal service hatch and tank body junction plane sealing situation in bad order.
After the utility model concrete mixing and transporting car service hatch seal arrangement compressed by hold-down bolt, two circular arc limits of seal rubber pad sealed the service hatch edge in conjunction with the midplane part, seal more effective.Seal rubber pad 3 is made of circular arc limit and the middle plane that two edges have Ф 5, as shown in Figure 2.On seal rubber pad 3 circumference 16 groups of bolts hole can be set, after assembling as shown in Figure 1, the uniform 16 groups of bolts assemblies of circumferencial direction.The circular arc limit of Ф 5 is at first pushed by the inner face of the outside of tank wall 2 and maintenance port lid 7 on the seal rubber pad 3, during extruding on the seal rubber pad 3 the circular arc limit of Ф 5 at first be out of shape, at first tank wall 2 and maintenance port lid 7 are carried out once sealing after the modification, along with continuous increase to the Bolt Tightening Force square, the plane of sealing gasket intermediate portion also can be pushed by the inner face of tank wall 2 and maintenance port lid 7, modification, then secondary seal is carried out at this position, obviously more a lot of after the sealing than plane sealing effect.
