Abstract
The invention relates to the field of tool fittings, in particular to a pneumatic jacking device. The pneumatic jacking device comprises an upper clamping plate and a lower clamping plate which are connected by virtue of a right-angled framework, wherein the upper end of the right-angled framework is in contact with the upper surface of the upper clamping plate, the lower end of the right-angled framework is in contact with the lower surface of the lower clamping plate; a cylindrical hole is formed in the center of the upper clamping plate, an anti-skidding block is arranged in the cylindrical hole, the anti-skidding block is fixed by virtue of a screw on the side wall of the cylindrical hole; a pneumatic jacking machine is arranged at the center of the upper surface of the lower clamping plate; the pneumatic jacking machine comprises a regulating rod positioned at the center of the lower surface of the lower clamping plate, wherein the top end of the regulating rod is propped against the pressure block, the regulating rod is driven by a gas cylinder. According to the pneumatic jacking device, provided by the invention, the pressure block is driven by the gas cylinder to move up and down to form clamping force between the pressure block and the anti-skidding block; meanwhile, the spring can be used for preventing damages due to oversized clamping force; the pneumatic jacking device is simple in structure, convenient to use and practical to some extent.
Description
Technical field
The present invention relates to tool fitting field, particularly point out a kind of pneumatic jacking-up device.

Summary of the invention
The object of this invention is to provide a kind of pneumatic jacking-up device, moved up and down, form clamping force between briquetting and non-slipping block by air cylinder driven briquetting, simultaneously spring can place the excessive and damage that causes of clamping force, and structure is simple, easy to use, has certain practicality.
The technical scheme realizing the object of the invention is as follows:
Pneumatic jacking-up device, comprise train wheel bridge and lower plate, described train wheel bridge is connected by right angle frame with lower plate, it is characterized in that, described right angle frame upper end contacts with train wheel bridge upper surface, lower end contacts with lower plate lower surface, also comprise described train wheel bridge center and be provided with cylindrical hole, non-slipping block is provided with in cylindrical hole, non-slipping block is fixed by the screw on cylindrical hole sidewall, described lower plate upper surface center is provided with pneumatic jack device, described pneumatic jack device comprises the adjusting rod being positioned at lower plate lower surface center, briquetting is withstood on described adjusting rod top, described adjusting rod passes through air cylinder driven.
Further, described both sides, briquetting upper end are also provided with balance weight.
Further, also regulating spring is provided with between described balance weight lower surface and lower plate upper surface.
Further, described adjusting rod is also positioned by dog screw, and described adjusting rod is provided with the equidistant screw for locating.
After adopting said structure, the invention has the beneficial effects as follows: moved up and down by air cylinder driven briquetting, between briquetting and non-slipping block, form clamping force, simultaneously spring can place the excessive and damage that causes of clamping force, structure is simple, easy to use, has certain practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, pneumatic jacking-up device, comprise train wheel bridge 1 and lower plate 2, described train wheel bridge 1 is connected by right angle frame 3 with lower plate 2, it is characterized in that, described right angle frame 3 upper end contacts with train wheel bridge 1 upper surface, lower end contacts with lower plate 2 lower surface, also comprise described train wheel bridge center and be provided with cylindrical hole, non-slipping block 4 is provided with in cylindrical hole, non-slipping block is fixed by the screw 5 on cylindrical hole sidewall, described lower plate upper surface center is provided with pneumatic jack device, described pneumatic jack device comprises the adjusting rod 6 being positioned at lower plate lower surface center, briquetting 7 is withstood on described adjusting rod 6 top, described adjusting rod is driven by cylinder 8.
Described both sides, briquetting upper end are also provided with balance weight 9.
Regulating spring 10 is also provided with between described balance weight lower surface and lower plate upper surface.
Described adjusting rod is also positioned by dog screw 11, and described adjusting rod is provided with the equidistant screw 12 for locating.
Concrete, moved up and down by air cylinder driven briquetting, form clamping force between briquetting and non-slipping block, spring can place the excessive and damage that causes of clamping force simultaneously, and structure is simple, easy to use, has certain practicality.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
