Abstract
The invention relates to a support hinge device for preventing a dumper oil cylinder from generating bending moment, bending deformation of the oil cylinder is avoided, and normal operation of the oil cylinder is guaranteed. The support hinge device comprises a carriage, a frame and the oil cylinder. The oil cylinder is connected with the frame through a hinge. The carriage is connected with the frame through a hinge. The oil cylinder is connected with the front end of the carriage through a hinge. The oil cylinder is connected with the frame through an arc support device. The oil cylinder can swing towards optional directions. The arc support device is a bulb hinge support, a bulb is mounted on the oil cylinder, a spherical gland is connected to a bulb seat through a screw, the bulb is restrained in the bulb seat, and the oil cylinder swings towards optional directions by using the bulb seat at a center. Due to the fact the oil cylinder can swing towards optional directions by using the bulb seat or a joint bearing as the center, during ascending and descending and when the frame under stressed bending deformation leads the carriage to drive the oil cylinder to swing leftwards and rightwards, the stressed direction is continuously consistent with the direction of an oil cylinder axis, and reliability and the service life of the oil cylinder are improved.
Description
Technical field
The present invention relates to technical field of engineering machinery, particularly a kind of dumping car oil cylinder that prevents produces the supporting hinge device of bending moment.
Technical background
Dumping car railway carriage, vehicle frame and oil cylinder are to interconnect (as accompanying drawing 1) with hinge, traditional dumping car vehicle frame is connected supporting hinge structure (as accompanying drawing 2) with oil cylinder at present, be that oil cylinder can rotate around the axial direction of bolster, realize dumping car lifting and decline swing, but vehicle frame is subjected to external force effect vehicle frame bending, railway carriage drives oil cylinder and prolongs oil cylinder axis direction swing (as accompanying drawing 3), this bolster hinge arrangement can not be realized this direction rotation, and under the constraint of bolster, oil cylinder produces bending moment, easily make oil cylinder produce flexural deformation, cause damage.
Summary of the invention
The purpose of this invention is to provide a kind of dumping car oil cylinder that prevents and produce the supporting hinge device of bending moment.It has avoided oil cylinder flexural deformation, guarantees the oil cylinder normal operation, has improved reliability and service life.
Technical scheme of the present invention is as follows:
It comprises railway carriage, vehicle frame and oil cylinder, and oil cylinder is connected with hinge with vehicle frame, and railway carriage is connected with hinge with vehicle frame, and oil cylinder is connected with hinge with the compartment front end, it is characterized in that: the cambered surface bearing set is adopted in oil cylinder and vehicle frame junction, and oil cylinder is swung to any direction.
Described cambered surface bearing set adopts the bulb hinged support, and bulb is installed on the oil cylinder, and the sphere gland is connected on the ball cap with screw, and bulb is constrained in the ball cap, and oil cylinder is any direction swing centered by ball cap.
Described cambered surface bearing set be oil cylinder with adopt outside vehicle frame is connected oscillating bearing hinged support, oscillating bearing to place in the bearing seat on the oil cylinder, with adapter shaft that oil cylinder is rack-mount, oil cylinder is any direction swing centered by oscillating bearing.
Advantage of the present invention is; Because oil cylinder can both be swung by any direction centered by ball cap or oscillating bearing, when realizing lifting and decline, also can satisfy vehicle frame because the stress deformation bending causes railway carriage to drive oil cylinder when swinging, remain and be subjected to force direction with oil cylinder axis direction unanimity, make oil cylinder not produce bending moment, avoided oil cylinder flexural deformation, guarantee the oil cylinder normal operation, improved reliability and service life.

Fig. 2 is present traditional dumping car vehicle frame and oil cylinder hinge engaging structure scheme drawing.
Fig. 3 railway carriage drives oil cylinder and prolongs oil cylinder axis direction swing scheme drawing.
Fig. 4 is the present invention program one structural representation.
Fig. 5 is the present invention program two structural representation.
The specific embodiment
Oil cylinder 5 stretches out or shrinks when dumping car is worked, and makes railway carriage 1 upset, realizes lifting, decline function.Vehicle frame is subjected to the effect of external force under the situation of Uneven road, and vehicle frame about 3 distorts, and causes railway carriage 1 to drive oil cylinder 5 and swings with the oil cylinder axis direction, does not produce moment of flexure for making oil cylinder, adopts two kinds of schemes in oil cylinder 5 and vehicle frame 3 supporting junctions.
Embodiment 1
It comprises railway carriage, vehicle frame and oil cylinder, oil cylinder 5 is connected with vehicle frame 3 usefulness hinges 4, and railway carriage 1 is connected with vehicle frame 3 usefulness hinges 2, and oil cylinder 5 is connected with hinge 6 with compartment 1 front end, it is characterized in that: the cambered surface bearing set is adopted in oil cylinder 5 and vehicle frame 3 junctions, and oil cylinder is swung to any direction.
The cambered surface bearing set adopts bulb hinged support (as accompanying drawing 4), is that bulb 7 is installed on the oil cylinder 5, and sphere gland 9 usefulness screws 10 are connected on the ball cap 8, and bulb 7 is constrained in the ball cap 8, and oil cylinder is any direction swing centered by ball cap 8.
Embodiment 2
The cambered surface bearing set adopts oscillating bearing (as accompanying drawing 5), be that oscillating bearing 15 usefulness jump rings 16 are constrained in the bearing seat 13, bearing seat 13 is installed on the oil cylinder 5, with adapter shaft 14 oil cylinder 5 is installed on the support 12, support 12 is fixed on the railway carriage 1, and oil cylinder is any direction swing centered by oscillating bearing 15.Two kinds of schemes also can satisfy vehicle frame when realizing lifting and decline because stress deformation bending when causing railway carriage 1 to swing, remain and be subjected to force direction with oil cylinder 5 axis direction unanimities, make oil cylinder 5 not produce bending moment, avoided oil cylinder flexural deformation, guarantee the oil cylinder normal operation, improved reliability and service life.Wherein oil cylinder 5 is connected with vehicle frame 3 usefulness hinges 4, and railway carriage 1 is connected with vehicle frame 3 usefulness hinges 2, and oil cylinder 5 is connected with railway carriage 1 usefulness hinge 6.Bulb hinged support or oscillating bearing hinged support are adopted in oil cylinder 5 and vehicle frame 3 junctions.
