The low-vacuum pipeline maglev high-speed vehicle overcomes problems such as the friction between the wheels and the track and air resistance by traveling inside the nu beam, and finally realizes a high-speed operation of 1000 km / h.

[0003] Among the multiple detection indexes of the nu beam, the nu beam deflection is very important index data. The nu beam deflection detection is to detect the lower "u"-shaped "steel structure + prestressed concrete" part. The nu beam deflection detection is an important link in the maglev transportation system project to ensure the structural safety of the nu beam, avoid the nu beam from breaking, and improve the structural stability of the maglev transportation system. When detecting the nu beam deflection, it is necessary to measure multiple points on the nu beam, and when measuring different points, it is necessary to adjust the support points of the nu beam correspondingly to avoid the influence of the support point position on the measurement position of the measurement point.

The rotation of the cam drives the movable end of the third telescopic rod to reciprocate in the axial direction.

[0040] Then the controller controls the second annular electromagnet 56 to be de-energized, enabling the second annular electromagnet 56 and the rotating rod 521 to relatively slide and rotate in the axial direction. At the same time, the controller controls the first annular electromagnet 522 to be energized. The first annular electromagnet 522 adsorbs to the rotating rod 521. The rotating rod 521 rotates to drive the first annular electromagnet 522 to rotate. The first annular electromagnet 522 rotates to drive the lifting screw 523 to rotate. The lifting screw 523 rotates to cause the connecting plate 531 to move away from the base 1 in the axial direction of the lifting screw 523. The movement of the connecting plate 531 drives the second housing 53 to move away from the base 1. The movement of the second housing 53 drives the two clamping plates 58 to move away from the base 1. The movement of the two clamping plates 58 drives the pipe beam 3 to move away from the base 1, lifting the horizontal height of the pipe beam 3 and disengaging it from the sliding housing 41, facilitating the adjustment of the position of the sliding housing 41.

[0041] The movement of the second housing 53 drives the first lifting spur gear 532 to move away from the base 1 at the same time. Since the first lifting spur gear 532 meshes with the first rack 511, the first lifting spur gear 532 rotates while moving. The rotation of the first lifting spur gear 532 drives the third rack 541 to move away from the base 1. The movement of the third rack 541 drives the third housing 54 to move away from the base 1. The movement of the third housing 54 drives the second lifting spur gear 542 to move at the same time. Since the second lifting spur gear 542 meshes with the second rack 533, the second lifting spur gear 542 rotates while moving. The rotation of the second lifting spur gear 542 drives the fourth rack 551 to move away from the base 1. The movement of the fourth rack 551 drives the fourth housing 55 to move away from the base 1.

The counterweight 64 is sleeved and threadedly connected to the transmission screw 62. The counterweight 64 abuts against the pipe beam 3.

[0043] While the lifting assembly 5 lifts the pipe beam 3, the controller controls the first electromagnetic shaft 65 and the second electromagnetic shaft 66 to be energized. The first electromagnetic shaft 65 adsorbs the guide rod 61, and the second electromagnetic shaft 66 adsorbs the transmission screw 62. The fourth housing 55 moves in a direction away from the base 1. The movement of the fourth housing 55 drives the first electromagnetic shaft 65 and the second electromagnetic shaft 66 to move. The movement of the first electromagnetic shaft 65 and the second electromagnetic shaft 66 drives the guide rod 61 and the transmission screw 62 to move synchronously. The movement of the guide rod 61 and the transmission screw 62 drives the counterweight 64 to move, so that the counterweight 64 is separated from the pipe beam 3.

[0044] When it is necessary to adjust the deflection force application point of the pipe beam 3, the controller controls the third annular electromagnet 631 to be energized. The third annular electromagnet 631 adsorbs the rotating rod 521. The rotation of the rotating rod 521 drives the third annular electromagnet 631 to rotate. The rotation of the third annular electromagnet 631 drives the first driving bevel gear 63 to rotate. The rotation of the first driving bevel gear 63 drives the first driven bevel gear 621 to rotate. The rotation of the first driven bevel gear 621 drives the second electromagnetic shaft 66 to rotate. The rotation of the second electromagnetic shaft 66 drives the transmission screw 62 to rotate.
