The method comprises the following specific steps:

1) Lifting operation

When the interface platform 1 is at the lowest height, the included angle of the two arms of the scissor pair 208 is close to 180 degrees, and the lifting with load has high requirement on the output torque of the motor at the moment; in the lifting process, along with the gradual reduction of the included angle of the two arms of the scissor pair 208, the demand of the vertical displacement motion on the output torque of the motor is rapidly reduced. In order to reduce the difficulty of initial lifting, spring elements are arranged at four corners below the top frame, and when the interface platform 1 is lifted from the lowest position, the spring elements are in a compressed state to release elastic potential energy, so that the requirement of actual load on the output torque of the motor is reduced.

2) Translational operation

The control system of the remote control platform lifts the bottom frame 202 by controlling four servo motors 201 at four corners of the second lifting mechanism to work cooperatively until the height distance between the bottom frame 202 and the lower table surface or the ground can be inserted into the translation transport table 3, then the translation transport table 3 is remotely controlled to move to the lower part of the bottom frame 202 automatically, the bottom frame 202 with the upper layer structure is lowered until the bottom frame 202 is contacted with the lifting table surface 301 of the translation transport table 3, at the moment, the four servo motors 201 continue to work, as the bottom frame 202 with the nut sleeve on the screw rod lifting table can not be lowered continuously, the screw rod can drive the disc type supporting legs 214 at the bottom to lift relative to the bottom frame, when the disc type supporting legs 214 are separated from the ground, the servo motors 201 can stop moving, after the bottom frame 202 and the lifting table 301 are fixed through the limiting mechanism, the translation transport table 3 is started, and the whole calibration device is transferred to a proper position.

When the calibration device works, the reverse operation of the process is implemented, the translation transport table 3 is evacuated, and the detection device on the interface board 101 can work at the lowest height.

3) Posture adjustment operation

Because a fit clearance exists between the screw rod structure and the nut sleeve, the remote control platform can realize the fine adjustment of the inclination angle of the interface board 101 by independently controlling the servo motors 201 at the four corners of the second lifting mechanism to independently work, and adjust the interface board to a horizontal state or a non-horizontal state. The model number YS80B5-0.75KW of the screw rod lifter is adopted in the embodiment, the specification of the screw rod is Tr40 x 7, and the maximum horizontal inclination angle of each side of the interface board 101 can be controlled between 2 and 5 degrees.

The utility model discloses calibration device is at the during operation, and the bottom is direct to contact with ground (or in order to avoid the influence that the unevenness in ground brought, also can only support through the disc type base 214 in four corners, and control bottom frame 202 exceeds ground 1 ~ 2 mm). Before and after the test, the calibration device needs to be preliminarily calibrated with the beam incident direction, manual adjustment can be used in the stage, short-distance transportation is carried out through translation operation, and remote control circuit board interfaces for controlling all servo motors are reserved on the table board of the interface board 101, so that remote control transportation and angle adjustment inside a factory building are finally realized.

The irradiation in the beam testing process is considered, and the calibration platform with the remote control function is commonly used. However, a calibration device which simultaneously meets the following conditions does not exist at present in China: the bearing capacity is 1500kg or more, the lowest height (from the ground) of the table top is not more than 500mm, the displacement precision reaches 0.03mm or more, and the turntable is compatible with different requirements; the calibration platform with the indexes can be compatible with the calibration test of most of space radiation detectors which are developed at home at present or may be developed in the future.

Practice proves that the highest safe load of the calibration device can reach 1620kg (design value 1200kg, design margin is 1.35) at present, the displacement precision can be controlled to be about 0.01mm based on the existing high-precision screw rod mechanism, the calibration device is superior to the existing calibration device, the calibration device can be compatible with the calibration test of most of the currently developed space radiation detectors in China, and further optimized space exists. Meanwhile, according to the result of actual test, under the condition of full load, the output current of the servo motor of the scissor lift is reduced to 2A from 5A by means of the auxiliary supporting mechanism, and is reduced by more than half. The calibration device of the embodiment is designed for the outer interface board, can provide a temperature and humidity environment and a table top inclination angle in the calibration test process of the space high-energy radiation detector, and integrates different types of rotary tables as required to provide the rotation angle requirement required by the calibration of the detector.
