Abstract
The utility model provides a connecting device for a lifting oil cylinder of a bulldozer. The upper end of the lifting oil cylinder is hinged to a lifting oil cylinder bracket welded to a front engine cover. A lifting oil cylinder support is welded to a shovel blade and provided with an oil cylinder connecting shaft. The lower end of the lifting oil cylinder is fixedly provided with a semi-arc watt seat. A bush cover with a semi-arc and the watt seat are buckled and connected through a bolt. A shaft hole formed by buckling of the watt seat and the bush cover contains the oil cylinder connecting shaft on the lifting oil cylinder support. When being replaced, the lifting oil cylinder can be replaced only by loosening the watt seat and the bush cover, disassembling and assembling are convenient, and the use performance of the bulldozer is further promoted.
Description
Technical field
The utility model relates to a kind of bulldozer lifting oil cylinder connecting device, for being connected of lift cylinder between bulldozer perching knife and front hood.
Background technology
Tradition bulldozer lift cylinder with lifting bracket by the mounting means being connected with pin, because bulldozer often produces collision in the course of the work, cause the connecting pin between lift cylinder and lifting bracket to produce bending, in the time changing lift cylinder, because the flexural deformation of connecting pin cannot be dismantled lift cylinder, cause the dismounting of lift cylinder very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of bulldozer lifting oil cylinder connecting device, has solved the problem that the lift cylinder that causes due to the connecting pin bending between lift cylinder and lifting bracket cannot dismounting.
The purpose of this utility model realizes as follows: lift cylinder upper end and lift cylinder support are hinged, on lift cylinder support welding mmi machine cover, there is the lift cylinder bearing being welded on perching knife, on lift cylinder bearing, there is oil cylinder connecting axle, lift cylinder lower end is fixed with watt seat of semi arch, together with being bolted with a watt seat make-up with the FE Tiler of semi arch, the axis hole that watt seat and FE Tiler make-up form contains the oil cylinder connecting axle on lift cylinder bearing.
Oil cylinder connecting axle middle part on lift cylinder bearing is spherical, watt seat and the semi arch middle part of FE Tiler are also corresponding semi-spherical shape, after watt seat and FE Tiler docking, form the axis hole corresponding with oil cylinder connecting axle, after connection, can avoid the relative lift cylinder bearing of lift cylinder to swing like this.
The utility model is only changing when lift cylinder and watt seat and FE Tiler need to be unclamped and just can change lift cylinder, and easy accessibility, has had further lifting to bulldozer complete machine functional performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A sectional drawing in Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, lift cylinder 1 upper end and lift cylinder support 4 are hinged, lift cylinder support 4 is welded on front hood, there is the lift cylinder bearing 2 being welded on perching knife, on lift cylinder bearing 2, there is oil cylinder connecting axle, lift cylinder 1 lower end is fixed with watt seat 5 of semi arch, together with being bolted with watt seat 5 make-ups with the FE Tiler 3 of semi arch, watt seat 5 contains the oil cylinder connecting axle on lift cylinder bearing 2 with the axis hole that FE Tiler 3 make-ups form, oil cylinder connecting axle middle part on lift cylinder bearing 2 is spherical, watt seat 5 and the semi arch middle part of FE Tiler 3 are also corresponding semi-spherical shape, after watt seat 5 and FE Tiler 3 docking, form the axis hole corresponding with oil cylinder connecting axle.
