[background technology]
At carrying out the specific (special) requirements of around-the clock static bearing test to raised floor among the standard P SA MOB PF2PS/SPU-1992 (raised floor-performance provision).
At present, the equipment of the static bearing test of raised floor all is to adopt universal testing machine.And general universal testing machine all is hydrostatic control, and load has fluctuation to a certain degree in the test, is not complete static state, and continuous working 24 hours, and to the loss of equipment, time cost is all bigger.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and provide a kind of modified raised floor static bearing test device.Adopt the principle of counter-force, utilize air compressor to provide stable source of the gas for cylinder, regulate air valve, control air pressure can be controlled the load that raised floor is applied, and can read the suffered load of sample by the sensor that is connected between cylinder and the sample.
Design the static bearing test device of a kind of modified raised floor for achieving the above object, comprise air compressor 1, air pressure regulator 2, baroswitch valve 3, cylinder 4, load transducer 6, electronics load display 7 and reaction frame 8, it is characterized in that: described cylinder 4 is installed on the reaction frame 8, described reaction frame below is provided with worktable 10, described cylinder connects baroswitch valve 3, air pressure regulator 2, air compressor 1 successively by pipeline, load transducer 6 is equipped with in piston 5 ends of described cylinder, and described load transducer 6 connects electronics load display 7 by circuit.
Described cylinder 4 upper ends are bolted to connection scalable screw rod 9, the be threaded top center position of reaction frame 8 of described scalable screw rod 9.
Described electronics load display 7, baroswitch valve 3 all are arranged on the reaction frame 8.
The utility model is compared with prior art, and whole device can well guarantee the stability of load, for the carrying of the static state in the ideal provides guarantee.According to the load of test needs, select the air pump of different ranges, by stable source of the gas, regulate air pressure and adjust load, and can continue guarantor year sample.Stable and equipment manufacturing cost cost of load and test duration cost are lower.The guarantor who is fit to very much above-mentioned standard is carried requirement and the similar test that has continuous guarantor to carry requirement.The static bearing test that can be widely used in all kinds of raised floors.

Among the figure: 1 is that air compressor, 2 is that air pressure regulator, 3 is that baroswitch valve, 4 is that cylinder, 5 is that piston, 6 is that load transducer, 7 is that electronics load display, 8 is that reaction frame, 9 is that scalable screw rod, 10 is a worktable.
[embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As shown in the figure, the utility model comprises air compressor 1, air pressure regulator 2, baroswitch valve 3, cylinder 4, load transducer 6, electronics load display 7 and reaction frame 8, described cylinder 4 upper ends are bolted to connection scalable screw rod 9, the be threaded top center position of reaction frame 8 of described scalable screw rod 9, the fixedly connected worktable 10 in described reaction frame 8 bottoms, described cylinder connects baroswitch valve 3 successively by pipeline, air pressure regulator 2, air compressor 1, load transducer 6 is equipped with in piston 5 ends of described cylinder, described load transducer 6 connects electronics load display 7, described electronics load display 7 by circuit, baroswitch valve 3 all is arranged on the reaction frame 8.
Air compressor of the present utility model can provide stable source of the gas for equipment.Air pressure regulator can be controlled the air pressure size that flows in the cylinder.Be installed on demonstration that the load transducer of piston lower end can be instant when front air cylinder to load that sample applied.Regulate the load that sample bears by regulating air valve.
Principle of work of the present utility model: air compressor 1 can produce a stable source of the gas, and it is stored in the big air reservoir, by pipeline gases at high pressure are connected to air pressure regulator 2, baroswitch valve 3 is transferred to the air inlet gear, gas can continue to flow in the cylinder 4, along with the increase of cylinder internal gas pressure, the piston 5 in the cylinder will move downward thereupon, and the sample on the worktable is produced downward pressure.Between piston and sample, be connected a load transducer 6, can by electronics load display 7 instant demonstrate the power that piston applies sample.At this moment, can control the size of air pressure by the rotation air pressure regulator, and then control piston is to sample institute applied pressure.After loading end, switch valve is transferred to the exhaust gear, the air pressure in the removal cylinder.Reaction frame 8 can provide a stable strong point for cylinder, and scalable screw rod 9 can make cylinder be adjusted to suitable height.
The utility model is not subjected to the restriction of above-mentioned embodiment; other any do not deviate from change, the modification done under spirit of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
