Description
Technical field
The invention belongs to the technical field of engineering machinery braking member.More particularly, the present invention relates to a kind of braking system of engineering machinery brake cylinder.
Background technique
In the prior art, the brake cylinder that braking system of engineering machinery is used is because the required braking force of loader is larger, the tensile stress load of the long-time bearing high strength of cylinder bottom.
As depicted in figs. 1 and 2, because weldquality is bad, brake cylinder bottom circumferential weld continues to be subject to, after very large pulling force, easily to cause the risk hidden danger of tearing, and finally causes serious insecurity, product failure, even accidents caused.
Summary of the invention
The invention provides a kind of braking system of engineering machinery brake cylinder, its objective is in order to improve the join strength of cylinder barrel and end cap, eliminate potential faults.
To achieve these goals, the technological scheme that the present invention takes is:
Braking system of engineering machinery brake cylinder of the present invention, comprises cylinder barrel, end cap, brake spring, piston and piston rod, in the circular hole of the end of described cylinder barrel, is provided with circular groove; Described end cap outer round surface is provided with step, and it is positioned at outer end is little cylindrical section, and the inner is large cylindrical section, and this large cylindrical section and inner hole of cylinder form and be slidably matched; In described circular groove, establish the Steel Cable Baffle Ring of ring, the internal diameter of its ring is less than the diameter of bore of cylinder barrel; Described end cap step plane contacts with described Steel Cable Baffle Ring; In the outer end of described cylinder barrel, between described cylinder barrel and end cap, be welded to connect.
The steel wire axis of described Steel Cable Baffle Ring, coordinates the cylndrical surface forming to overlap with the described large cylindrical section of end cap step with inner hole of cylinder.
Turning is carried out in the whole outer end of described cylinder barrel and end cap, makes the end face of described cylinder barrel end face and end cap form same plane.
Described Steel Cable Baffle Ring is elastic steel wire check ring.
The present invention adopts technique scheme, and the braking force that the end cap of brake cylinder bears mainly concentrates on Steel Cable Baffle Ring, can eliminate the potential faults causing because weldquality is bad; Improved the safety and reliability of product.

Fig. 3 is structural representation of the present invention;
Fig. 4 is the partial structurtes schematic diagram at the F place in Fig. 3.
In figure, be labeled as:
1, end cap, 2, Steel Cable Baffle Ring, 3, cylinder barrel.
Embodiment
Contrast accompanying drawing below, the description by embodiment, is described in further detail the specific embodiment of the present invention, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technological scheme.
Structure of the present invention as expressed in Fig. 3, Fig. 4, is a kind of braking system of engineering machinery brake cylinder, comprises cylinder barrel 3, end cap 1, brake spring, piston and piston rod.Brake cylinder suction port is connected with hand braking valve, and piston rod is connected with the brake arm of break.
The working principle of above-mentioned braking system of engineering machinery brake cylinder:
During brake off, air pressure enters into the A chamber of cylinder barrel 3 assemblies by suction port, and air pressure promotes piston assembly and moves forward in B chamber, and push rod is moved forward together, and the brake arm that push rod connects is opened, in driving states;
During braking, the A chamber gas of cylinder barrel 3 assemblies is discharged, and under the effect of brake spring, piston assembly bounces back rapidly with push rod, pulls brake arm simultaneously, forms braking, makes wheel lock up.
In order to solve the problem of prior art existence and to overcome its defect, realize the join strength that improves cylinder barrel and end cap, eliminate the goal of the invention of potential faults, the technological scheme that the present invention takes is:
As shown in Figure 3 and Figure 4, braking system of engineering machinery brake cylinder of the present invention, in the circular hole of the end of described cylinder barrel 3, is provided with circular groove; Described end cap 1 outer round surface is provided with step, and it is positioned at outer end is little cylindrical section, and the inner is large cylindrical section, and this large cylindrical section and cylinder barrel 3 endoporus form and are slidably matched; The Steel Cable Baffle Ring 2 of establishing ring in described circular groove, the internal diameter of its ring is less than the diameter of bore of cylinder barrel 3; Described end cap 1 step plane contacts with described Steel Cable Baffle Ring 2; In the outer end of described cylinder barrel 3, between described cylinder barrel 3 and end cap 1, be welded to connect.
Described Steel Cable Baffle Ring 2 is elastic steel wire check ring; Elastic steel wire check ring, by spring expanding, is clamped in circular groove, makes Steel Cable Baffle Ring 2 become circlip;
Counter the pushing back of port direction by from end cap 1 to cylinder barrel 3, makes described end cap 1 step plane contact with described Steel Cable Baffle Ring 2; And the outer surface of end cap 1 is concordant with cylinder barrel 3 port surfaces;
Then by cylinder barrel 3 and end cap 1 welding;
After having welded, described cylinder barrel 3 carries out turning with the whole outer end of end cap 1, makes the end face of described cylinder barrel 3 end faces and end cap 1 form same plane.
The steel wire axis of described Steel Cable Baffle Ring 2, overlaps with the cylndrical surface that cylinder barrel 3 endoporus fitting surfaces form with the described large cylindrical section of end cap 1 step.Like this, the steel wire of Steel Cable Baffle Ring 2, the axis of steel wire of take is boundary, and half is in circular groove, and half just in time blocks outwards motion of end 1, the larger axial force that may bear brake spring outside circular groove; The braking force that bear brake cylinder end is mainly concentrated on Steel Cable Baffle Ring 2, can avoid the serious insecurity causing because weldquality is bad.
In sum, technological scheme of the present invention has improved the Security of product, has increased reliability, has eliminated potential faults.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or without improving, design of the present invention and technological scheme are directly applied to other occasion, all within protection scope of the present invention.
