Abstract
The invention relates to a lifting stage with positioning devices. The lifting stage comprises a stage surface, a lifting mechanism, a control system and a plurality of positioning devices, wherein the lifting mechanism is hidden under the ground and is capable of driving the stage plane to move up and down, and the positioning devices are located at the bottom of the stage plane and are distributed around the center of the stage plane; each positioning device comprises a lock pin, and the lock pin stretches outwards from the center of the stage plane and stretches out of the outer edge of the stage plane; and when the stage plane is higher than the ground surface and needs to be horizontally placed, the lock pin stretches out of the stage plane and can be established on the ground surface, and when the stage plane needs to descend, the lifting mechanism control the stage plane to descend after the lock pin shrinks into the stage plane. According to the lifting stage, on one hand, the lock pins can bear the gravity of the stage plane, so that the bearing pressure of the lifting mechanism is reduced, and the service life of the lifting mechanism is prolonged; and on the other hand, the lock pins are linked with the lifting mechanism and are protected during the operation, so that the damage of the lock pins caused by the motion of the lifting mechanism is avoided. The lifting stage is smart in design, strong in practicability and low in cost.

Obviously, above-mentioned elevator stage has the disadvantage that
1), after stage disposes, the whole weight of loaded hydraulic cylinder, therefore, the quantity of hydraulic cylinder wants many, and have to work asynchronously, and structure certainly will be caused complicated, defect that cost is high；
2), no matter stage is in rising or horizontal (especially during horizontal), and hydraulic cylinder is constantly in stress, and its service life is relatively low, must cause the rising of use cost.
Summary of the invention
In order to overcome the defect of prior art, the present invention provides the elevator stage with positioner of a kind of improvement.
For solving above technical problem, the present invention takes techniques below scheme:
A kind of elevator stage with positioner, it includes table top, hide and enable to the elevating mechanism of table top oscilaltion campaign, control system in underground, be positioned at multiple positioners of central distribution bottom table top and around table top, each positioner includes from the center of table top to external extension the outer peripheral lock pin of table top of emerging, when table top surface above Ground and when needing horizontal, lock pin stretches out outside table top and can ride upon on ground surface, when table top needs to decline, after lock pin is reduced to table top inside, elevating mechanism controls the decline of table top again.
Preferably, positioner also includes being positioned at bottom table top for driving the electric expansion bar of lock pin stretching motion.
Preferably, the electric expansion bar synchronization telescope of multiple positioners.
One according to the present invention is embodied as and preferred aspect, positioner also includes the monitoring system for recording lock pin collapsing length information, wherein monitoring system is connected with control system, when table top surface above Ground and when needing horizontal, lock pin is emerged table top outward flange, and when meeting the rated value L of monitoring default, lock pin stops stretching out；When table top needs to decline, lock pin is contracted to inside table top, and the shrinkage value shunk is equal to after L, and lock pin stops shrinking, and information is fed back to control system by monitoring system, and elevating mechanism controls the decline of table top again.
Concrete, lock pin is fixed with contact site, monitoring system includes the sensor rolling the rolling code device being arranged on lock pin and contacting with the contact site of lock pin, wherein rolling code device can set rated value, after contact site separates with sensor, rolling code device starts to record numerical value, and when rated value set by the length that lock pin stretches out meets rolling code device, lock pin stops stretching out；After lock pin contacts with sensor to the shrinkage value of central reduction equal to rated value and contact site, lock pin stops shrinking.
Additionally, table top is rounded；Positioner has four, and is uniformly distributed around the circumference of table top.
Preferably, elevating mechanism is positioned at the center bottom table top；Elevating mechanism includes scissor-type brace and the hydraulic jack driving scissor-type brace to launch or draw in.
Preferably, lock pin is cylindrical, and positioner also includes the guide holder being separately fixed at bottom table top, and lock pin is movably arranged on guide holder.
Due to the enforcement of above technical scheme, the present invention compared with prior art has the advantage that
One aspect of the present invention rides upon ground surface by lock pin so that lock pin can the gravity of loading floor, alleviate the bearing pressure of elevating mechanism, extend the service life of elevating mechanism；After lock pin is reduced to table top inside on the other hand, elevating mechanism controls table top again and declines so that lock pin and elevating mechanism are connected, and lock pin is carried out running protection, it is prevented that lock pin damages because of the motion of elevating mechanism, designs ingenious, practical.
Accompanying drawing explanation
