Abstract
The invention discloses a counter-force frame type jack calibration device. The counter-force frame type jack calibration device comprises a base platform, an ejector plate, vertical columns and a moving cart. The vertical columns are arranged between the base platform and the ejector plate. An ejector mechanism is arranged on the ejector plate. An auxiliary platform is arranged on one side of the base platform, adjacent to the base platform and equal to the base platform in height. A guide rail is arranged on the auxiliary platform and the base platform. The moving cart is arranged on the guide rail and comprises pulleys, a cart frame and a cart plate. The pulleys are matched with the guide rail and can be rotationally fixed on the cart frame. The cart frame is provided with two cart beams which are parallel to the guide rail. Four ejector devices are arranged on the cart beams of the cart frame. The cart plate is fixed on the four ejector devices. A boss is arranged on the base platform, and the height of the boss is higher than the height of the cart plate before the four ejector devices are ejected and smaller than the height of the cart plate after the four ejector devices are ejected. In a calibration experiment, pressure is only applied to the cart plate of the moving cart, and the calibration requirement of a large jack or a pressure sensor can be met.
Description
Technical field
The present invention 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, must be placed in lifting jack or pressure transducer on base frame, for some, large-scale lifting jack or pressure transducer etc. are larger by the weight of calibrating instrument, 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, can't realize directly with loop wheel machine, being moved on base frame by calibrating instrument.For this reason, be provided with travelling car on some reaction frame formula lifting jack caliberating devices, increased a substage in base frame one side, substage is adjacent with base frame and highly consistent, laid guide rail on substage and base frame, be provided with travelling car on guide rail, 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, to these, large-scale lifting jack or pressure transducer etc. are carried out 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 can't realize directly with loop wheel machine, moving to the problem on base frame, 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 can't bear 1000 tons with upward pressure.For this reason, above-mentioned reaction frame formula lifting jack caliberating device still can't meet large-scale lifting jack or the calibration request of pressure transducer.
Summary of the invention
For above-mentioned situation, the problem that quasi-solution of the present invention 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 present invention 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, its described travelling car comprises pulley, vehicle frame and sweep, and described pulley coordinates with guide rail and described pulley rotatably is 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 at the end away from base frame.
Adopt such scheme, reaction frame formula lifting jack caliberating device of the present invention, 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, makes 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 invention 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 the height of sweep higher than boss, travelling car can be moved on on base frame, then regulate four liftout attachments and fall after rise, make the height of the height of sweep lower than boss, at this moment sweep just is shelved on boss.Like this, when rating test, only the sweep of travelling car 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 invention can meet large-scale lifting jack or the calibration request of pressure transducer.
