[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 shown.

[0021] A platform structure for placing measuring instruments in a shield section comprises a horizontal plate 2, a vertical plate 3 and a support rod 5.

[0022] The horizontal plate 2 and the vertical plate 3 are both strip-shaped straight plates, which can be made of steel plates. The horizontal plate 2 is laid flat, one end of which is hinged to the upper part of the vertical plate 3, and the other end is suspended, so that the horizontal plate 2 and the vertical plate 3 intersect each other, and the horizontal plate 2 can rotate up and down around the hinge.

[0023] The support rod 5 is in the shape of a straight rod, with screw holes at both ends respectively, and its upper end is connected to the side of the horizontal plate 2 by a fixing bolt, and its lower end is movably connected to the lower end of the vertical plate 3 by an adjustment plate 6, so that the support rod 5, the horizontal plate 2 and the vertical plate 3 together form a triangular structure, so that the horizontal plate 2 is stably supported.

[0024] The adjustment plate 6 is in the shape of a short plate, and is provided with a long hole-shaped adjustment hole. An adjustment bolt is provided in the adjustment hole, which can move along the adjustment hole. The adjustment plate 6 is arranged in the same direction at the lower part of the vertical plate 3, so that the adjustment hole is vertically arranged, and the lower end of the support rod 5 is sleeved on the adjustment bolt, so that the angle between the horizontal plate and the vertical plate can be changed by moving the adjustment bolt up and down, thereby adjusting the horizontal state of the horizontal plate. At the same time, the connection point between the support rod 5 and the horizontal plate 2 is close to the suspended end of the horizontal plate 2, so that the adjustment is more convenient. Preferably, the support rod 5 is two, symmetrically arranged, so that the structure is more stable. Correspondingly, the adjustment plate is two pieces, symmetrically arranged.

[0025] The upper surface of the horizontal plate 2 is provided with a connection structure that can be connected to the measuring instrument. The connection structure includes a screw 1. The screw 1 is adapted to the connection hole of the measuring instrument, and its head is buried in the horizontal plate 2, and its threaded section protrudes from the upper surface of the horizontal plate 2, so that the connection hole of the measuring instrument can be screwed on the screw and firmly installed. Preferably, the screw 1 is arranged on the center line of the horizontal plate 2 and close to its suspended end, which is convenient for installation and adjustment.

[0026] The height of the vertical plate 3 is equivalent to the distance between two adjacent mounting holes of the shield segment, and an upper connecting plate 4 and a lower connecting plate 7 are respectively provided at the upper and lower ends thereof. The upper connecting plate 4 and the lower connecting plate 7 are both short plate-shaped, and their width is less than the width of the mounting hole of the shield segment, so that they are convenient to be placed in the mounting hole. Preferably, the angles between the upper connecting plate 4 and the lower connecting plate 7 and the vertical plate 3 are 120°-130°, so that they can better adapt to the curvature of the shield segment.

[0027] The upper connecting plate 4 and the lower connecting plate 7 are provided with a connecting hole I and a connecting hole II, respectively. The connecting hole I is a circular through hole, which can be sleeved on the end of the segment bolt 9 and then fastened with a nut. The connecting hole II is a circular through hole and is provided with a through notch, and the width of the notch is equivalent to the diameter of the segment bolt, so that the connecting hole II can be clamped on the end of the segment bolt and then fastened with a nut, which is convenient for installation and disassembly.

[0028] The connection hole I and the connection hole II are provided with gasket I and gasket II, respectively. The gasket I is a closed annular gasket, which is of the same size as the connection hole I and is fixed on the connection hole I, so that the nut can be more firmly screwed. The gasket II is an annular gasket with an opening, which is of the same shape and size as the connection hole II and is fixed on the connection hole II. Moreover, the opening corresponds to the notch, which not only facilitates the clamping connection with the segment bolt, but also makes the nut more firmly screwed.

[0029] Furthermore, it also includes a cushion block 8. The cushion block 8 is made of rubber and is in an arc-shaped block shape. Its width is equivalent to the width of the vertical plate 3, and its maximum height is greater than the maximum distance between the vertical plate and the shield segment. The cushion block 8 is arranged between the vertical plate and the shield segment, and is deformed by appropriate pressure, so that its bottom surface is close to the vertical plate, and its top surface is close to the shield segment, so that the vertical plate is effectively supported and its stability can be enhanced to prevent displacement or shaking. Preferably, the bottom surface of the cushion block 8 can be pasted on the back of the vertical plate 3 for easy installation.

[0030] The method of using the utility model is:

[0031] Preliminarily tighten the nuts at both ends of the support rod to form a triangular structure. Then, fit the connection hole I on the upper connecting plate onto the upper end of the segment bolt of the shield segment and preliminarily tighten it with a nut. Then, insert the connection hole II on the lower connecting plate into the lower end of the segment bolt and preliminarily tighten it with a nut. At the same time, make the pad close to the shield segment. Then, completely tighten the nuts at the upper and lower ends of the segment bolt to ensure a secure installation. Finally, screw the fixing holes of the measuring instrument onto the screw to complete the installation of the measuring instrument. At the same time, the adjusting bolt at the lower end of the support rod can be moved to adjust the horizontal state of the cross plate to meet the use requirements of the measuring instrument.

[0032] The utility model can be directly installed on the segment bolts at the joint of the shield segments, providing a stable platform structure for the shield measuring instrument that is not affected by the shield transportation equipment. In addition, the utility model does not need to drill holes and install bolts on the shield segments, which can effectively protect the existing finished segments and avoid quality problems on the segments.

[0033] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
