Abstract
The invention discloses an electric liquid push rod comprising an oil cylinder body, wherein a covering barrel is arranged on the periphery of the oil cylinder body. The covering barrel is in a layered structure and is composed of a rubber layer, a glass fiber cloth layer, an organic adhering layer and a glass fiber cloth layer from inside to outside. According to the electric liquid push rod, a sleeve is additionally arranged on the common base to separate a sealing piece from a heat source, so that the function of protecting the sealing piece is achieved and the service life of a product is greatly prolonged.
Description
Technical field
The present invention relates to a kind of Electrohydraulic push rod.
Background technique
Electrohydraulic push rod is a kind of straight journey actuator of mechanical-electrical-hydraulic integration, and being applicable to needs the reciprocating sliding campaign, and can carry out concentrating or program control of remote high-altitude and dangerous area, is widely used in industries such as metallurgy, electric power, mine, building.When common Electrohydraulic push rod uses in the high temperature place, exist Sealing fragile, greatly reduce the working life of product.
Summary of the invention
The present invention is directed to the existing technology deficiency, a kind of Electrohydraulic push rod that high-performance bag tube is set on traditional Electrohydraulic push rod is provided.
The present invention realizes through following technological scheme:
A kind of Electrohydraulic push rod comprises cylinder body, and said cylinder body periphery is provided with the bag tube, and this bag tube is a stratiform structure, is rubber layer, glass fibre layer of cloth, organic bonding layer, glass fibre layer of cloth from inside to outside.
Said Electrohydraulic push rod, said organic bonding layer is the organosilicon glue-line.
Said Electrohydraulic push rod, said bag barrel thickness is 3mm～15mm.
Beneficial effect of the present invention is:
The novel fire resistant Electrohydraulic push rod adds a sleeve pipe on the plain edition basis, Sealing and thermal source are separated, thereby reach the function of protecting Sealing, the working life of having improved product greatly.Rubber layer effectively raises the frictional force with the cylinder body surface, makes parcel closely; The glass fibre layer of cloth is through the organic silica gel bonding, and adhesive strength is high, and glass fiber cloth has good heat resistance, flex resistance, the working life on the cylinder body that improves greatly surface.
Description of drawings
Fig. 1 is the structural representation of Electrohydraulic push rod of the present invention;
Fig. 2 is the cross section structure schematic representation of bag tube of the present invention.
Among the figure: 1, motor; 2, fuel tank; 3, cylinder body; 4, the bag tube; 41, faying surface; 42, rubber layer; 43, the glass fibre layer of cloth; 44, organic bonding layer.
Embodiment
Electrohydraulic push rod of the present invention comprises motor 1, and fuel tank 2, cylinder body 3, cylinder body are provided with bag tube 4 outward, and this bag tube is a stratiform structure, is rubber layer 42, glass fibre layer of cloth 43, organic bonding layer 44, glass fibre layer of cloth 43 from inside to outside.
