Abstract
The utility model belongs to the technical field of elastic piston accessories and particularly relates to an elastic piston for a concrete pump. The elastic piston for the concrete pump is technically characterized by comprising a piston body, wherein the piston body is provided with a positioning hole, sealing rings and positioning rings, wherein lining metal rings are embedded into the positioning rings; the piston body is made of a rubber material and is high in acid-alkaline resistance, water resistance and high-temperature resistance performance; the overall strength is greatly improved; the lining metal rings are vulcanized with the rubber material on the outer side, so that the adhesion is firmer, and the service life is greatly prolonged; the piston does not need to be deformed, and slurry leakage can be avoided; the normal production of equipment is guaranteed; furthermore, the elastic piston is light in weight, and the energy waste is small.
Description
Technical field
The utility model belongs to piston technical field, relates in particular to concrete pump elastic piston.
Background technique
In fields such as building and bridge constructions, need to concrete conveyance be arrived to specified position with concrete pump, like this, not only improve working efficiency, but also saved construction cost.Directly affect construction speed and construction quality as the quality that uses elastic piston quality on concrete pump.The elastic piston using on concrete pump at present mainly contains following several: one, and the piston made from polyurethane material, under high-speed motion and hyperbaric environment, easily produces high temperature, working surface fusing, working life is short, easily causes spillage; Its two, adopt the piston made of rubber material, acidproof, alkaline-resisting, water-fast and resistance to high temperature strengthens, but intensity is little, yielding, causes spillage, the equipment that affects uses, and even causes device damage; Its three, the piston of front end adopts rubber material to make, at piston rear with sheet metal, to improve the intensity of piston, but sheet metal weight is large, seesaw in process at piston, consumed energy is large, and sheet metal and piston employing plane-plane contact, bonding strength is low, and sheet metal and piston easily depart from.
Model utility content
A kind of sealing intensity is good with regard to being to provide for the technical problem of solution of the present utility model, long service life, acid resistant alkali, water-fast and high temperature strength is strong, lightweight, the concrete pump elastic piston that is difficult for spillage.
The technical solution adopted in the utility model is: comprise piston only, this piston only, with positioning hole, seal ring and positioning ring, is inlaid with inner liner metal ring in described positioning ring.
Its additional technical feature is:
In the radially inside and outside bi-side of described inner liner metal ring with double wedge ring;
On described inner liner metal ring with axial hole, in this axial hole with the glue post of positioning ring integrative-structure.
Concrete pump provided by the utility model with elastic piston compared with prior art, have the following advantages: one, owing to comprising piston only, this piston only is with positioning hole, seal ring and positioning ring, in described positioning ring, be inlaid with inner liner metal ring, acid resistant alkali, water-fast good with resistance to high temperature, bulk strength strengthens greatly, inner liner metal ring adopts with the rubber material in outside and sulfides, bonding more firm, greatly strengthen working life, piston need not be out of shape, can not cause spillage etc., the equipment that guaranteed is normally produced, and lightweight, energy waste is few, its two, due in the radially inside and outside bi-side of described inner liner metal ring with double wedge ring, inner liner metal ring and rubber positioning ring are bonding more firm, have further prevented inner liner metal ring and positioning ring disengaging, its three, due on described inner liner metal ring with axial hole, in this axial hole with the glue post of positioning ring integrative-structure, glue post and positioning ring integrative-structure, further prevented that inner liner metal ring and positioning ring from departing from, lighter overall weight, has saved metallic material.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model concrete pump elastic piston;
Fig. 2 is the structural representation with the concrete pump elastic piston of double wedge ring;
Fig. 3 is the structural representation of using elastic piston on inner liner metal ring with the concrete pump of axial hole;
Fig. 4 is the plan view with the inner liner metal ring of axial hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model concrete pump is described in further details by structure and the use principle of elastic piston.
As shown in Figure 1, the utility model concrete pump elastic piston, comprises piston only 1, and piston only 1 is made up of rubber material, and this piston only, with positioning hole 2, seal ring 3 and positioning ring 4, is inlaid with inner liner metal ring 5 in positioning ring 4.Together with inner liner metal ring 5 adopts high temperature vulcanized being embedded in positioning ring 4.Acid resistant alkali, water-fast and resistance to high temperature good, bulk strength strengthens greatly, inner liner metal ring adopts with the rubber material in outside and sulfides, bonding more firm, greatly strengthen working life, and piston need not be out of shape, can not cause spillage etc., the equipment that guaranteed is normally produced, and lightweight, and energy waste is few.
As shown in Figure 2, in the radially inside and outside bi-side of inner liner metal ring 5, with double wedge ring 6, inner liner metal ring 5 is bonding more firm with rubber positioning ring 4, has further prevented that inner liner metal ring 5 and positioning ring 4 from departing from.
As shown in Figure 3 and Figure 4, on inner liner metal ring 5 with axial hole 8, in this axial hole 8 with the glue post 7 of positioning ring integrative-structure, glue post and positioning ring integrative-structure, further prevented that inner liner metal ring and positioning ring from departing from, lighter overall weight, has saved metallic material.
Protection domain of the present utility model is not only confined to above-described embodiment, as long as structure is identical by the structure of elastic piston with the utility model concrete pump, just drops on the scope of the utility model protection.
