Description

Technical Field

[0001] The present application belongs to the technical field of subway construction, and specifically relates to a multifunctional segment parameter measuring ruler. Background Art

[0002] In order to ease urban traffic pressure and promote rapid and sustainable economic development, many cities have incorporated subway construction into urban traffic planning. In subway construction, affected by construction quality and complex geological conditions, the assembled segments will have different degrees of misalignment, angulation, segment cracking and deformation, among which misalignment is the most common. There are two types of segment misalignment: one is inter-segment misalignment, which refers to the radial relative displacement at the joints of two adjacent segments in a ring of segments; the other is inter-ring misalignment, which refers to the relative displacement at the circumferential joints between two adjacent rings of segments. The current national standards require that inter-segment misalignment be less than 15mm and inter-ring misalignment be less than 10mm.

[0003] After the shield segments are assembled, how to measure the misalignment between segments and between rings in a portable and timely manner is an important process, but the existing measuring tools have the problems of low portability and single function. Utility Model Content

[0004] The utility model provides a multifunctional segment parameter measuring ruler, which solves the problems of low portability and single function of existing segment parameter measuring tools.

[0023] In order to enable those skilled in the art to better understand the content of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0024] As attached Figure 1 ~Attached Figure 4 As shown, the present application provides a multifunctional segment parameter measuring ruler, comprising:

[0025] A main ruler 4, wherein the main ruler 4 is provided with scales on both sides, wherein the scales start at the 0 scale at the lower end of the main ruler 4 and end at the maximum scale at the upper end of the main ruler 4;

[0026] A first secondary ruler 1, the first secondary ruler 1 is arranged on one side of the main ruler 4 and is fixedly connected to the main ruler 4 at the 0 scale;

[0027] A second secondary ruler 2, the second secondary ruler 2 is arranged at the other side of the main ruler 4 and is slidably connected to the main ruler 4;

[0028] The third secondary ruler 3 is arranged on the same side of the second secondary ruler 2 and is detachably connected to the main ruler 4 at the maximum scale.

[0029] The double-sided scale means that scales are set on both sides of the main scale 4. When using different sub-scales, different scales are used to achieve multiple uses of one scale. The present application can be used for both segment measurement and annular gap distance measurement. When measuring the segment, the first sub-scale 1 is placed on the segment at a lower position, and the second sub-scale 2 is moved to a position higher than the segment position. The difference between the first sub-scale 1 and the second sub-scale 2 is the offset distance of the segment. When measuring the annular gap, the third sub-scale 3 is placed at one end of the segment annular gap, and the second sub-scale 2 is moved to the other end of the annular gap. The difference between the third sub-scale 3 and the second sub-scale 2 is the width of the segment annular gap.

[0030] In one implementation of the present application, the second secondary ruler 2 and the third secondary ruler 3 are connected to the main ruler 4 via a slider 5, and the slider 5 is provided with a tension bolt 6 for fastening the slider 5 to the main ruler 4. When used for the first time, the third secondary ruler 3 is installed at the top of the scale of the main ruler 4 and the tension bolt 6 is fixed, and it remains stationary during the entire use process. Alternatively, when measuring the misalignment distance of the pipe segment, it is not necessary to install the third secondary ruler 3, and a flexible combination can be performed during use. The second secondary ruler 2 and the third secondary ruler 3 are installed in the same manner. When adjusting, loosen the tension bolt 6 to make the slider 5 movable. When the second secondary ruler 2 moves to a suitable distance, tighten the tension bolt 6 and then read the scale, and determine the measurement result based on the scale difference.

[0031] In a specific embodiment of the above implementation, as shown in the attached Figure 1 As shown, the second secondary ruler 2 and the third secondary ruler 3 are in the shape of a right-angled trapezoid, the right-angled sides of the second secondary ruler 2 and the third secondary ruler 3 are connected to the main ruler 4, and the second secondary ruler 2 and the third secondary ruler 3 are arranged in mirror image relative to each other. The sharp corner section of the right-angled trapezoid can penetrate into a narrow space to accurately measure the annular seam. The reading of the straight edge should be used as the standard. In specific measurements, the second secondary ruler 2 and the third secondary ruler 3 can also be flipped over for use according to actual conditions.

[0032] In one implementation of the present application, the first secondary ruler 1 and the second secondary ruler 2 are provided with a convex button 7, and the first secondary ruler 1 and the second secondary ruler 2 are both provided with a matching protective cover 9, and the protective cover 9 is provided with a concave button 8 (matching the convex button 7) inside. Figure 3 (not shown). The convex button 7 and the concave button 8 can protect the secondary ruler after being matched, so as to prevent the sharp corners of the secondary ruler from cutting the measuring operator. There is also a set of concave buttons 7 and convex buttons 8 outside the protective cover 9, which are used to connect the two protective covers 9 to each other.

[0033] In one implementation of the present application, a level circle is provided at the geometric center of the main ruler 4, an indicator circle is provided at the center of the level circle, and a level bubble is provided in the level circle. When the level bubble is located in the indicator circle, the main ruler 4 is in a horizontal state. In some construction scenarios, it is necessary to judge the horizontal height difference between two components. In specific operations, the second secondary ruler 2 can be moved to the 0 scale and fixed, and the first secondary ruler 1 and the second secondary ruler 2 are placed on the two components respectively. The position of the level bubble is observed. When the level bubble is located in the center indicator circle, it is considered that the placement points of the first secondary ruler 1 and the second secondary ruler 2 are at the same horizontal height.

[0034] The above description is only the basic principle and preferred embodiments of the present invention. Improvements and substitutions made by those skilled in the art based on the present invention belong to the protection scope of the present invention.
