Background technique
In the processing of heavy components or product, assembling process, it usually needs lifted component or product by hoistable platform
It is raised to certain altitude and is fixed in present level, to be further processed or to assemble.Hydraulic elevating platform has load
Greatly, the features such as at low cost and each link for being widely used in heavy components or process of producing product.In practical application, for height
It is high to spend positioning accuracy request, and positioning height needs the case where constantly regulate according to different product, realizes using hydraulic system
Higher cost, and using hydraulic system realize positioning after, when load vary widely when, position error can also become larger.
For example, poling technique requires to penetrate steel pipe in outer tube in " tube-in-tube " formula insulating tube production process, and keep two pipes
Center line coincidence error is in a certain range.Therefore, during poling, it is desirable that the workbench liftable of steel pipe or outer tube is simultaneously
It is accurately positioned, to ensure two tube hub line coincidence errors in a certain range, and adapts to the operation of different model pipe fitting.Meanwhile
During poling, the load of hoistable platform can change with the feeding of poling, it is therefore desirable to the height of hoistable platform
Position has good retentivity.
Based on the above demand, the present invention devises a kind of flat for lifting in heavy components or production and assembling process
The position-limit mechanism of platform, which can be accurately located hoistable platform specified height, while implement mechanical position limitation to platform,
It prevents from causing podium level error because of the variation of load.Mechanism positioning height can carry out antenatal adjusting in a certain range.
