With this structure, the lower fixing frame 502 can be continuously lifted as the upper fixing frame 501 is lifted, thereby changing its own position and ensuring the stability of the vertical support 503.

[0035] like Figure 6-14 In the preferred solution, the standard section 2 includes a frame 201, a cross bar 202 and an inclined bar 203 are arranged in the frame 201, and a one-way locking platform 7 is detachably arranged on the inclined bar 203, and the one-way locking platform 7 includes a base 701, a rotating plate 702 is hinged on the base 701, a limiting plate 704 is arranged at the bottom of the base 701, the top of the rotating plate 702 abuts against the bottom of the lower fixed frame 502, and a top rod 703 is also arranged on the base 701, and the top rod 703 abuts against the inner wall of the boss 505. With this structure, when the lower fixed frame 502 moves upward, the rotating plate 702 is pushed to rotate upward, and when the lower fixed frame 502 is separated from the rotating plate 702, the rotating plate 702 returns to the initial state under the action of its own weight, and at the same time, the limiting plate 704 supports the rotating plate 702 to maintain the state of being vertical to the standard section 2, and at this time, the lower fixed frame 502 falls on the rotating plate 702, and the rotating plate 702 provides a limiting basis for the lower fixed frame 502, which is convenient for the subsequent measurement work.

[0036] In the preferred solution, a baffle 705 is provided on the upper side of the base 701, and the top rod 703 is inserted into the baffle 705. A first locking ring 708 and a mushroom head 709 are provided on one side of the top rod 703. A spring 714 is sleeved on the top rod 703, and the spring 714 is located between the first locking ring 708 and the baffle 705.

A second locking ring 804 and a second nut 805 are provided on the round rod 803, and the second locking ring 804 and the second nut 805 are respectively located on the inner and outer sides of the lower fixed frame 502. Since the standard section 2 is made of a variety of profiles, the most common ones are round steel, square steel and angle steel, and fixed plates for facilitating the limiting of the lifting cylinder are generally provided at the four corners of the standard section 2, the free movement space is limited. Due to this structure, the right-angle plate 801 as a V-shaped structure can better limit the freedom during movement, while ensuring that the lower fixed frame 502 is provided with a guiding and limiting effect, ensuring that the axis of the lower fixed frame 502 remains coaxial with the upper fixed frame 501 when it moves, thereby ensuring the smooth movement of the vertical support 503 and the overall measurement is accurate and efficient.

For the convenience of manufacturing, the lower fixing frame 502 can adopt the same structure as the upper fixing frame 501, so that the first motor 516 drives the second gear 515 to drive the vertical support 503 to rotate around the upper fixing frame 501 and the lower fixing frame 502, the first support ring 511, the second support ring 512 and the third support ring 513 can better clamp the second gear 515, and the overall operation stability is good.

[0039] In a preferred solution, the second gear 515 is rotatably mounted on the extension plate 525, and the extension plate 525 is connected to the vertical support 503 via the mounting block 519. With this structure, the position and state of the second gear can be conveniently adjusted as needed, and the force is more balanced.

With this structure, the second motor 521 drives the drag chain 517 to move in the height direction, so that the position of the prism 518 is adjusted without changing the position of the lower fixed frame 502, so that the monitoring of the standard section 2 can be completed. In the actual operation process, the lifting process of the standard section 2 is a time-consuming process with a long vacuum period, so the drag chain 517 can be used to better expand the measurement point range of the prism 518, ensure the real-time and comprehensive measurement data, and facilitate timely correction of the state of the installed standard section 2.

[0041] In the preferred embodiment, the base 701 is a C-shaped structure, the base 701 and the cross bar 202 are plugged in, a slope 713 is provided at the bottom of one side of the rotating plate 702, two ear plates 712 are provided in parallel on the side wall of the base 701, the rotating plate 702 is hinged by the plug rod 711 and the ear plate 712, and two third through holes 715 are provided in parallel on the base 701, and bolts 707 are passed through the third through holes 715, and the bolts 707 are fixed to the base 701 through the first nut 710. With this structure, the base 701 can be quickly fixed on the standard section 2. In the installation technical specifications, direct structural changes are not allowed to the standard section 2. Therefore, this method will not destroy the structural stability and supporting strength of the standard section itself, and the overall connection rigidity will not be affected. It is easy to install and disassemble, and has good use effect. The cross bar 202 is generally located in the middle position of the standard section 2, and the operation space is large.
