The working principle of the invention is as follows: before using, as shown in fig. 1, the lifting or descending of the 1 drive work platform of four lift hydraulic stem 8 of accessible control, thereby satisfy the user demand to work platform 1 co-altitude, the transport and the placing of the large-scale part of being convenient for simultaneously, electric putter 6 can drive spacing telescopic link 4 and go up and down, thereby highly adjust the position of survey needle subassembly 5, thereby further improve the range that the survey needle can record, make the measuring space increase, be convenient for large-scale spare part's measurement, avoid the not enough influence measuring condition in space to take place.

Before measurement, balance correction can be carried out on the measuring machine, as shown in fig. 5, the rotatable rotating handle 23 drives the balance correction plate 19 to descend through the rotating shaft 16 and the lifting rope 17, when the balance correction plate 19 is in contact with the fixed plate 13, as shown in fig. 6, the pressure probes 22 at the bottom of the balance correction plate 19 are subjected to the reaction force of the fixed plate 13 under the action of gravity, so that the pressure probes 22 detect corresponding pressure, and then the pressure probes are transmitted by the pressure sensors 18, the parallel degree of the balance correction plate 19 and the fixed plate 13 can be judged according to the distribution condition of the pressure, so that the horizontal degree of the plane where the working platform 1 is located is judged, and therefore the lifting hydraulic rods 8 can be respectively driven to adjust the working platform 1 to be horizontal, the measurement work is not influenced by the ground inclination, the measurement precision is improved, and the accuracy of the measurement result is ensured.

When balance correction is carried out, as shown in fig. 6, in addition to the dead weight of the pressure sensor 18, the balance correction plate 19 and the pressure probe 22, the balance correction plate 19 is kept horizontal, the connecting ropes 20 and the weight 21 which are uniformly arranged on two sides of the balance correction plate 19 can provide external gravity restraint, and the horizontal degree of the balance correction plate 19 is further improved, so that the balance correction effect of the working platform 1 is ensured, meanwhile, as shown in fig. 6, before and after correction, the rotating handle 23 can be clamped on the elastic clamping jaw 24 to limit the balance correction plate 19, useless continuous pressure measurement of the pressure sensor 18 is avoided, the four lifting hydraulic rods 8 are independently driven and do not influence each other, the balance fine adjustment correction can be realized by matching with the rotation of the rotating ball 10 and the sliding of the T-shaped sliding block 12, and the balance correction is flexible and convenient.

Before and after measurement, the air-floating slide rail 2 can be automatically cleaned, the transmission motor 29 drives the transmission screw rod 26 to rotate through driving the transmission shaft 30, thereby driving the movable sleeve rod 31 to move back and forth along the axial direction of the limit guide rod 27 through the threaded sleeve 32, thereby driving the absorbent cotton cleaning pad 35 to wipe and clean the air-floating slide rail 2, as shown in fig. 7, ensuring the surface of the air-floating slide rail 2 to be clean, reducing the influence on the sliding of the floating block 3, loading cleaning agents such as alcohol and the like in the plurality of cleaning agent storage bottles 36, the surface of the absorbent cotton cleaning pad 35 is dropped through the dropper 37 and absorbed and diffused by the absorbent cotton cleaning pad 35, the cleaning effect is improved, when cleaning to the position of the floating block 3, the cleaning rod 33 can be rotated to make the absorbent cotton cleaning pad 35 pass through the side of the floating block 3, then the cleaning rod 33 is reset to continue cleaning, so that the whole air-floating slide rail 2 can be cleaned, and the operation is convenient and simple.

After the absorbent cotton cleaning pad 35 is used for a long time, as shown in fig. 7, the two slidable side limiting sliding sleeves 40 remove the limitation on the mounting plate 38, then the lifting rod 43 is pulled to drive the limiting insertion pin 39 to be drawn out of the absorbent cotton cleaning pad 35 through the mounting plate 38, so that the limitation on the absorbent cotton cleaning pad 35 is removed, and the absorbent cotton cleaning pad 35 can be taken down for cleaning or replacement, which is very convenient, meanwhile, in the cleaning process, the cleaning air blower 42 moves along with the moving sleeve rod 31, so that impurities, dust or some small parts on the air floatation slide rail 2 can be blown away by means of wind power, the impurities are prevented from scratching the surface of the air floatation slide rail 2 or damaging the air floatation slide rail 2, and the service life of the air floatation slide rail 2 is shortened.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
