The weight of case beam can reach 900 tons, if be loaded with the carrying implement pivot stud of case beam, tire can suffer the effect of shearing force and be damaged.In the patent No. is in the utility model patent " rubber-tyred carrying implement " of ZL200620130084.1, a kind of supporting mechanism has been described, this supporting mechanism is made up of support cylinder that is installed in the vehicle frame below and the base that is positioned at oil cylinder piston bar overhanging end, when tire sets is spent at heavily loaded pivot stud 90, can act on ground by supporting mechanism, make tire sets unsettled, avoid tire to suffer the destruction of shearing force.The supporting mechanism that this patent is described can only adapt to smooth in the road surface upper support, and in the time need turning in non-smooth-riding surface, the base of supporting mechanism can not be supported on the road surface by pulsation-free.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provide a kind of can be at the passive jacking apparatus of tilted road surface.
In order to reach above purpose, the technical scheme that the utility model is taked is: a kind of jacking apparatus of rubber-tyred carrying implement, being arranged between the tire sets of this jacking apparatus interval, it comprises the oil cylinder mount pad that is fixedly installed on carrying implement vehicle frame below, the oil cylinder that is installed in described oil cylinder mount pad below; The piston rod of described oil cylinder is connected with a bulb, described bulb below is provided with supporting seat, described supporting seat is provided with the ball-and-socket that matches with described bulb, and described supporting seat is provided with the bulb cover plate, and described bulb is limited between described ball-and-socket and the described bulb cover plate.
Preferably, described jacking apparatus comprises guide fixed block, guide bush, the axis of guide, described guide fixed block is fixedly installed on the casing wall of described oil cylinder, described guide bush is installed on the described guide fixed block, described supporting seat is provided with ear plate base, and the bottom of the described axis of guide is hinged with described ear plate base, the upper end is slidingly fitted with described guide bush is connected.
Because the enforcement of above technical scheme, the utility model compared with prior art, have following advantage: adopted the structure of bulb and ball-and-socket, made supporting seat adjust self bevelled angle according to the road surface automatically, jacking apparatus can be played a supporting role on the bevelled road surface by actv..
Description of drawings
Accompanying drawing 1 is a front view of the present utility model;
Accompanying drawing 2 is the A-A cutaway view in the accompanying drawing 1;
Accompanying drawing 3 is that B in the accompanying drawing 1 is to partial view (enlarged view);
Wherein: 1, oil cylinder mount pad; 2, oil cylinder; 4, bulb; 5, supporting seat; 6, ball-and-socket; 7, bulb cover plate; 8, guide fixed block; 9, guide bush; 10, the axis of guide; 11, ear plate base.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Shown in accompanying drawing 1 to 3, a kind of jacking apparatus of rubber-tyred carrying implement, being arranged between the tire sets of this jacking apparatus interval, it comprises the oil cylinder mount pad 1 that is fixedly installed on carrying implement vehicle frame below, be installed in the oil cylinder 2 of oil cylinder mount pad 1 below, the cylinder body of oil cylinder 2 is installed in the oil cylinder mount pad 1, its piston rod stretches out downwards, this piston rod is connected with a bulb 4, bulb 4 belows are provided with supporting seat 5, supporting seat 5 is provided with the ball-and-socket 6 that matches with bulb 4, supporting seat 5 is provided with and is used to the bulb cover plate 7 that prevents that supporting seat 5 from dropping, and bulb 4 is limited between ball-and-socket 6 and the bulb cover plate 7.For supporting seat 5 is supported on the ground more stably, the plane is arranged in the bottom surface of supporting seat 5.
As shown in Figure 3, jacking apparatus also comprises guide fixed block 8, guide bush 9, the axis of guide 10, guide fixed block 8 is fixedly installed on the casing wall of oil cylinder 2, guide bush 9 is installed on the guide fixed block 8, supporting seat 5 is provided with ear plate base 11, and the bottom of the axis of guide 10 and ear plate base are 11 hinged, the upper end is slidingly fitted with guide bush 9 and is connected.When supporting seat 5 rotated, the axis of guide 10 that inserts in guide bush 9 moved up and down, and the axis of guide 10, ear plate base 11 can limit the scope that supporting seat 5 rotates, and had increased the stability of supporting seat 5.
Carrying implement is when being loaded with case beam pivot stud, oil cylinder 2 drives supporting seat 5 and drops to ground, make tire sets unsettled, tire sets turns to then, shearing force is to the destruction of tire when having avoided turning to, and after turning in place, the piston rod of oil cylinder 2 is regained, supporting seat 5 rises, and carrying implement is supported on the ground by tire sets again.Owing to be connected by bulb 4 and ball-and-socket 6 between supporting seat 5 and the oil cylinder 2, so when carrying implement is in non-smooth-riding surface and turns to, supporting seat 5 can be according to the bevelled angle of road surface automatic compensation own, the bottom surface of supporting seat 5 is adjacent on the bevelled road surface, has played the effect of steady support.
Above embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present invention and is implemented; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the present utility model.
