Abstract
The invention discloses an automatic-inflating airbag protection device. The airbag protection device adopts the main structure that a group of air bags is arranged below a base for placing a large mass comparator; an operating platform is arranged on the outer sides of the air bags; the periphery of the base is in contact with the operating platform in a matched way through damping limiting part; the air bags are connected with a pressure switch; the pressure switch is connected with and controls an air pump through circuits; the air pump is sequentially connected with an FRL (filter, relief valve and lubricator), a deflation ball valve and air bags through pneumatic pipelines. The starting and stopping of the air pumps is controlled through the pressure switch when the device is operated, so as to ensure that the pressure in the air bags is always within a set value range, air in the air bags is discharged through the deflation ball valve when the device is not operated, and then the large mass comparator is stably located onto a supporting seat. According to the device, safe and reliable protection can be provided for the transportation of the large mass comparator, and the operation of the comparator is not affected after the comparator reaches a destination.
Description
Technical field
The present invention relates to a kind of protection of instrumentation device of measurement verification, refer in particular to the large mass comparator protective device carried in counterweight standard set-up mobile laboratory.
Background technology
F
2grade counterweight standard set-up mobile laboratory carries out calibration operation in the amount of needs biography scene, but the large mass comparator that it carries, belong to high-accuracy measurement instrument, have very high requirement to traffic condition and environment for use.Therefore, need development one can not only protect large mass comparator in transportation, and can also not affect the protective device of large mass comparator operation in use.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of charging-self type air bag protecting device; this protective device is arranged in counterweight standard set-up mobile laboratory; this charging-self type air bag protecting device can provide safe and reliable protection for the transport of large mass comparator, and does not affect again the operation of comparator after arriving destination.
The technical problem to be solved in the present invention is realized by following scheme: charging-self type air bag protecting device, be arranged in counterweight standard set-up mobile laboratory, comprise base, workbench, air bag, air pump, pressure switch, it is characterized in that: one group of air bag is set below the base of the large mass comparator of described placement, it is workbench outside air bag, base surrounding is by contacting damping spacing cooperation with workbench, described one group of air bag is connected with pressure switch, pressure switch is by circuit connection control air pump, air pump is by pneumatic line and three linked piece, venting ball valve, airbags connects.
The principle of work of this charging-self type air bag protecting device is: inflated by air pump when charging-self type air bag protecting device runs, air enters air bag by pneumatic line, base and large mass comparator jack-up are about about 20mm after expanding by air bag, prescribe a time limit when intracapsular pressure reaches in set pressure, control air pump by pressure switch and stop inflating; After a period of time, when intracapsular pressure, to drop to setting lower in limited time, controls air pump start working by pressure switch, guarantees that pressure in air bag is always in setting range.When not needing charging-self type air bag protecting device to run, air pump cutting out, opening venting ball valve and air in air bag is released, large quality comparation and base are steadily dropped on workbench.
Advantage of the present invention is: use this charging-self type air bag protecting device can provide safe and reliable protection for the transport of large mass comparator, and do not affect again the operation of comparator after arriving destination.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is charging-self type air bag protecting device sectional side elevation.
Fig. 2 is charging-self type air bag protecting device gas circuit schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, below the base 2 placing large mass comparator 1, arrange one group of air bag 4, be workbench 5 outside air bag 4, base 2 surrounding arranges damping spacing 3.Base 2 surrounding is coordinated with workbench 5 contacted by damping spacing 3.Air bag 4 is connected with pressure switch 9, and pressure switch 9 is by circuit connection control air pump 6, and air pump 6 is connected with three linked piece 8, ball valve 10 of exitting, air bag 4 successively by pneumatic line 7.
Inflated by air pump 6 when charging-self type air bag protecting device runs, air enters air bag 4 by pneumatic line 7, after air bag 4 expands, base 2 and large mass comparator 1 jack-up are about about 20mm, prescribe a time limit when pressure in air bag 4 reaches in set pressure, control air pump 6 by pressure switch 9 and stop inflating; After a period of time, when pressure drop in air bag 4, to setting, lower controlling air pump 6 by pressure switch 4 starts working in limited time, guarantees that pressure in air bag 4 is always in setting range.When not needing charging-self type air bag protecting device to run, air pump 6 cutting out, opening venting ball valve 10 and air in air bag 4 is released, large quality comparation 1 and base 2 are steadily dropped on workbench 5.
