Description
Technical field
The utility model relates to a kind of reaction frame formula lifting jack, pressure sensor calibrating device, is more specifically a kind of large-scale reaction frame formula lifting jack, pressure sensor calibrating device, belongs to test apparatus manufacturing technology field.
Background technology
Common reaction frame formula lifting jack caliberating device structure is quite simple, generally comprises base frame, top board and column, and column is located between base frame and top board, and top board is provided with ejecting mechanism, and ejecting mechanism generally adopts hydraulic-driven.By the ejecting mechanism on base frame and top board, lifting jack, pressure transducer etc. is exerted pressure, demarcate lifting jack or pressure transducer etc.
While demarcating lifting jack or pressure transducer, lifting jack or pressure transducer must be placed on base frame, larger by the weight of calibrating instrument for some large-scale lifting jack or pressure transducer etc., often need by loop wheel machine, it to be moved, because the top of the base frame of reaction frame formula lifting jack caliberating device is provided with top board, cannot realizes directly and will be moved on base frame by calibrating instrument with loop wheel machine.For this reason, on some reaction frame formula lifting jack caliberating devices, be provided with travelling car, in base frame one side, increased a substage, substage is adjacent with base frame and highly consistent, on substage and base frame, laid guide rail, on guide rail, be provided with travelling car, travelling car can move between substage and base frame like this, due to the substage side that is top board, travelling car can be moved on on substage, loop wheel machine can directly will be moved on substage by calibrating instrument, and then travelling car is moved on on base frame, these large-scale lifting jack or pressure transducer etc. are carried out to rating test by calibrating instrument.The reaction frame formula lifting jack caliberating device group of said structure has entered substage and travelling car, solved by calibrating instrument and cannot realize directly and move to the problem on base frame with loop wheel machine, but when rating test, ejecting mechanism on top board need to be to being applied larger power by calibrating instrument, lifting jack or pressure transducer for some super large-scales, its pressure can be over 1000 tons, namely travelling car at least will bear same pressure, very high to the requirement of the physical strength of travelling car like this, and in fact travelling car cannot bear 1000 tons with upward pressure.For this reason, above-mentioned reaction frame formula lifting jack caliberating device still cannot meet large-scale lifting jack or the calibration request of pressure transducer.
Utility model content
For above-mentioned situation, the problem that the utility model quasi-solution is determined is to provide a kind of reaction frame formula lifting jack caliberating device that can meet the calibration request of large-scale lifting jack or pressure transducer.
For reaching above-mentioned purpose, the utility model has adopted following technical scheme: a kind of reaction frame formula lifting jack caliberating device, and it comprises base frame, top board, column and travelling car, and described column is located between base frame and top board, and described top board is provided with ejecting mechanism; One side of described base frame is provided with substage, described substage is adjacent with base frame and highly consistent, described substage and base frame are provided with guide rail, described travelling car is arranged on guide rail, described in it, travelling car comprises pulley, vehicle frame and sweep, and described pulley coordinates with guide rail and described pulley is rotatably fixed on vehicle frame, and described vehicle frame has two car beams with guide rail parallel, the car beam of described vehicle frame is provided with four liftout attachments, and described sweep is fixed on four liftout attachments; Described base frame is provided with boss, the height of sweep when the height of described boss does not eject higher than four liftout attachments, the height of sweep while ejecting lower than four liftout attachments.
Described top board is mobily connected on column.The vehicle frame of described travelling car is provided with push rod in the one end away from base frame.
Adopt such scheme, reaction frame formula lifting jack caliberating device of the present utility model, the car beam due to vehicle frame is provided with four liftout attachments on the one hand, and sweep is fixed on four liftout attachments, like this, by regulating four liftout attachments to make highly can regulating up and down of sweep.On the other hand, base frame is provided with boss, the height of sweep when the height of described boss does not eject higher than four liftout attachments, the height of sweep while ejecting lower than four liftout attachments.Like this when reaction frame formula lifting jack caliberating device of the present utility model is used, travelling car is moved on on substage, loop wheel machine can directly will be moved on substage by calibrating instrument, by regulating top sweep on four liftout attachments, make the height of sweep higher than the height of boss, travelling car can be moved on on base frame, then regulate four liftout attachments to fall after rise, make the height of sweep lower than the height of boss, at this moment sweep is just shelved on boss.Like this, when rating test, only the sweep of travelling car is produced to pressure, avoided other parts of travelling car to bear very large pressure.Therefore, reaction frame formula lifting jack caliberating device of the present utility model can meet large-scale lifting jack or the calibration request of pressure transducer.
