The utility model has the advantages of deformation avoidance of rubber-covered tires, good reliability, simple structure and low cost.
Description
Technical field
The utility model relates to a kind of lifting body of vehicle-mounted turntable.
Technical background
The utilization in stage industry now of the severe duty vehicle-mounted turntable of function complexity is comparatively general, the cydariform turntable that uses as Grand National Theatre drama field, the vehicle-mounted turntable that the Beijing TV Center video theatre uses etc.Because turntable rotates demand, need adopt support wheel to support in the turntable bottom.
Conventional support wheel adopts steel material, under the very dark situation of general foundation ditch, steel support wheel operation noise transmission can satisfy the performance demand to the stage face substantially through overdamping, but under the more shallow situation of foundation ditch with regard to out of reach stage performance demand, simultaneously because the rigid transmission of steel wheel, vibration problem also is difficult for solving, as shown in Figure 1.Therefore generally steel wheel is changed system into antiageing encapsulate steel core support wheel, energy noise abatement and absorbing etc. during operation, but when stage does not move for a long time, encapsulate is taken turns long-term pressurized and can be out of shape, when using, needs then can produce the phenomenon that startup is not got up or produced impulsion, can produce bigger vibration and noise when roller moves to deformation position simultaneously, as shown in Figure 2.Therefore a kind of device that when not transporting shape for a long time wheel is de-orbited need be provided.
Summary of the invention
For overcoming the above-mentioned shortcoming of prior art, the utility model provides a kind of can avoid the distortion of encapsulate wheel, and good reliability is simple in structure, the lifting body of vehicle-mounted turntable with low cost.
The lifting body of vehicle-mounted turntable is characterized in that: described turntable comprise be fixed on the turntable support, can and provide the actuating unit of power for described jacking unit with several jacking unit of stage jack-up;
Described jacking unit comprises the jacking support, be fixed on the described jacking support, with described actuating unit bonded assembly thrust mechanism, by hinge and described jacking support bonded assembly two connecting rod mechanisms, and the block piece that stops described thrust mechanism to move forward; Described block piece is fixed on the described jacking support.
Further, the lower end of the boxed rod in described two connecting rod mechanisms and the upper end of lower link are hinged, and described lower link is connected with described jacking support by hinge, and the upper end of described boxed rod is connected with the stage structure; Described thrust mechanism is connected with the articulated section of described boxed rod and lower link.
Further, the upper end of described boxed rod can be connected the slide block of stage jack-up with one by hinge, and described slide block is slidably mounted in a chute, and described chute is fixed on the below of stage.
Further, described block piece be positioned at described slide block away from described thrust mechanism one side.
Further, described thrust mechanism is oil cylinder (or cylinder etc.), and the piston rod of described oil cylinder is connected with described two connecting rod mechanisms; Described actuating unit is a hydraulic workstation.
Technical conceive of the present utility model is: after stage is finished using, start hydraulic workstation, the articulated section that the piston rod of oil cylinder promotes boxed rod and lower link travels forward, being blocked part up to described articulated section withstands, slide block breaks away from the encapsulate support wheel with stage jack-up, hydraulic workstation quits work, and jacking is finished; This moment, described two connecting rod mechanisms were crossed the dead point, were blocked the part location, and guaranteeing does not need to keep-up pressure in the hydraulic circuit with support turntable steelframe again, thereby guaranteed the hydraulic medium no leak.
This lifting body has the following advantages:
1, can select less hydraulic-driven power to realize bigger top lift.
2, self-insurance press tool supporting mechanism need not dispose antiseep device and energy storage pressurizer.
3, internal force oneself is offset, to reduce the influence to the equipment body steel structure.
4, by crank-type mechanical position limitation block riser tubing internal pressure, guarantee that each cylinder body all moves, all act on to reach each strong point.

The specific embodiment
With reference to accompanying drawing, further specify the utility model:
The lifting body of vehicle-mounted turntable, described vehicle-mounted turntable comprise be fixed on the ride support, can and provide the actuating unit 2 of power for described jacking unit 1 with several jacking unit 1 of stage jack-up;
Described jacking unit comprises jacking support 11, be fixed on the described jacking support 11, with described actuating unit bonded assembly thrust mechanism 12, by hinge and described jacking support bonded assembly two connecting rod mechanisms, and the block piece 14 that stops described thrust mechanism 12 to move forward; Described block piece 14 is fixed on the described jacking support 11.
The lower end of the boxed rod 131 in described two connecting rod mechanisms and the upper end of lower link 132 are hinged, and described lower link 132 is connected with described jacking support 11 by hinge; Described thrust mechanism 12 is connected with the articulated section of described boxed rod 131 and lower link 132.
The upper end of described boxed rod 131 can be connected the slide block 133 of stage jack-up with one by hinge, and described slide block 133 is slidably mounted in a chute 134, and described chute 134 is fixed on the agent structure of vehicle-mounted turntable.
Described block piece 14 be positioned at described slide block 134 away from described thrust mechanism 12 1 sides.
Described thrust mechanism 12 is an oil cylinder, and the piston rod of described oil cylinder is connected with described two connecting rod mechanisms; Described actuating unit is a hydraulic workstation.
Technical conceive of the present utility model is: after stage is finished using, start hydraulic workstation, the articulated section that the piston rod of oil cylinder promotes boxed rod 131 and lower link 132 travels forward, being blocked part 14 up to described articulated section withstands, slide block 133 breaks away from the encapsulate support wheel with stage jack-up, hydraulic workstation quits work, and jacking is finished; This moment, described two connecting rod mechanisms were crossed the dead point, were blocked the part location, and guaranteeing does not need to keep-up pressure in the hydraulic circuit with support turntable steelframe again, thereby guaranteed the hydraulic medium no leak.
