Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The embodiment of the utility model provides a support device for branch conductor measurement, which can solve the technical problems in the related art that installing the support frame by drilling holes on the tunnel segment easily damages the steel bars in the segment, reduces the strength of the tunnel segment, and makes it difficult to use it normally.

[0035] Figure 1A support device for branch line measurement provided by an embodiment of the utility model comprises: a slide 1, a plurality of connecting members 3 and a support assembly 4, wherein the slide 1 is arranged on the tunnel segment 2 along the vertical direction, a connecting block 31 is provided at the top of each connecting member 3, the connecting block 31 is embedded in the slide 1, a connecting rod 32 is provided in the middle of the connecting block 31, the support assembly 4 is used to support a measuring instrument, the support assembly 4 comprises a vertical plate 41, a plurality of through holes 411 are provided on the vertical plate 41, one connecting rod 32 passes through one through hole 411 correspondingly, and is used to fix the vertical plate 41 on the tunnel segment 2.

[0036] The bracket device of the embodiment of the utility model is provided with a slide groove, multiple connecting parts and a support assembly. The slide groove is arranged on the tunnel segment in the vertical direction. A connecting block is provided at the top of each connecting part. The connecting block is embedded in the slide groove. A connecting rod is provided in the middle of the connecting block. The support assembly is used to support the measuring instrument. The support assembly includes a vertical plate. The vertical plate is provided with multiple through holes. One connecting rod passes through one through hole correspondingly, and is used to fix the vertical plate to the tunnel segment. By passing the connecting rod through the through hole on the vertical plate, the connecting block is embedded in the slide groove and rotated 90 degrees in the slide groove, and the connecting block is fixed in the slide groove, so that the vertical plate is fixed to the tunnel segment. There is no need to drill holes on the tunnel segment to install expansion bolts, which ensures the quality of the steel bars in the tunnel segment, improves the strength of the tunnel segment, and enables it to be used normally.

[0037] As an optional implementation, in a utility model embodiment, see Figure 3 As shown, the connecting block 31 is a rectangular structure, and the size of the connecting block 31 matches the size of the slide 1. The size of the connecting block 31 is 18mm in length, 12mm in width and 6mm in thickness. The size of the slide 1 is 14mm in outer gap width and 20mm in inner gap width. When in use, the connecting block 31 is first embedded in the slide 1 along the vertical direction, i.e., parallel to the slide 1, and then the connecting block 31 is rotated 90 degrees in the slide 1 so that the connecting block 31 is parallel to the horizontal plane, i.e., perpendicular to the slide 1. Since the length of the connecting block 31 is slightly larger than the outer gap width of the slide 1, the connecting block 31 can be fixed in the slide 1 and will not slide, i.e., there is no need to drill holes and install expansion bolts when fixing the support frame, thereby ensuring the quality and integrity of the tunnel segment.

[0038] As an optional implementation, in a utility model embodiment, see Figure 3As shown, the connecting rod 32 is provided with a thread, and the thread is used to be rotatably connected with a nut. After the connecting rod 32 passes through the through hole 411, the connecting rod 32 and the through hole 411 are fixed by using the nut, that is, the vertical plate 41 is fixed at the rear end of the connecting rod 32 by tightening the nut.

[0039] As an optional implementation, in a utility model embodiment, see Figure 2 As shown, there are three through holes 411, one through hole 411 is provided above the vertical plate 41 along the vertical direction, and two through holes 411 are provided below the vertical plate 41 along the vertical direction. The upper part of the vertical plate 41 is fixed to the tunnel segment 2 by using one of the connecting members 3 to pass through the through holes 411, and the lower part of the vertical plate 41 is fixed to the tunnel segment 2 by using two of the connecting members 3 to pass through the through holes 411, thereby improving the connection stability between the vertical plate 41 and the tunnel segment 2, so that the utility model can more stably support and carry the measuring instrument.

[0040] As an optional implementation, in a utility model embodiment, see Figure 4 As shown, the slide 1 is made of a rubber strip material, which is odorless and non-toxic, has the characteristics of not being afraid of high temperatures and resisting severe cold, and still retains its original strength and elasticity at 300 degrees Celsius and minus 90 degrees Celsius. It also has good electrical insulation, oxygen resistance, aging resistance, light resistance, aging resistance, mildew resistance, and chemical stability, and can be fitted to various smooth surface materials. The rubber strip is elastic, and the connecting block 31 can be directly embedded in the slide 1 and fixed without the need for bolts.

[0041] As an optional implementation, in a utility model embodiment, see Figure 1 As shown, the support assembly 4 also includes: a transverse plate 42, which is arranged on the vertical plate 41 along the horizontal direction and is used to support the measuring instrument. The transverse plate 42 is vertically fixed to the vertical plate 41 and cooperates with the vertical plate 41 to form a bracket, and the transverse plate 42 acts as a supporting platform to place and support the measuring instrument to be used, thereby assisting in completing the tunnel measurement.

[0042] As an optional implementation, in a utility model embodiment, see Figure 1As shown, the steel support device for branch conductor measurement also includes: a side reinforcing plate 5, which is arranged between the vertical plate 41 and the horizontal plate 42, and one end of the side reinforcing plate 5 is connected to the vertical plate 41, and the other end is connected to the horizontal plate 42 to form an oblique support structure. The side reinforcing plate 5 is arranged between the vertical plate 41 and the horizontal plate 42, and forms a triangular structure with the vertical plate 41 and the horizontal plate 42, and at the same time transfers the load on the horizontal plate 42 to the vertical plate 41 and the tunnel segment 2, thereby enhancing the stability and load-bearing capacity of the utility model.

[0043] As an optional implementation, in a utility model embodiment, see Figure 1 As shown, the angle between the side reinforcing plate 5 and the vertical plate 41 is 50 degrees to 60 degrees. The side reinforcing plate 5 forms an oblique support structure between the vertical plate 41 and the horizontal plate 42. Since the oblique support angle is too small, it is not convenient for construction. The angle between the side reinforcing plate 5 and the vertical plate 41 is within the range of 50 degrees to 60 degrees. At the same time, the side reinforcing plate 5 mainly bears horizontal loads. At this time, the horizontal component of the oblique support bearing capacity is higher than the vertical component. Selecting a larger angle can improve the support utilization rate of the side reinforcing plate 5, which can further improve the stability of the utility model.

[0044] As an optional implementation, in a utility model embodiment, see Figure 1 As shown, the vertical plate 41 and the horizontal plate 42 are fixedly connected by welding, and the side reinforcing plate 5 and the vertical plate 41 and the horizontal plate 42 are also fixedly connected by welding. The welding fixing method has a simple structure, easy operation, high joint strength, good density, metal saving, high productivity and low cost.

[0045] As an optional implementation, in a utility model embodiment, see Figure 1 As shown, the plurality of connecting parts 3, the supporting assembly 4 and the side reinforcing plate 5 are all made of steel. The steel has good toughness and plasticity, uniform material, high structural reliability, weldability, heat resistance and good assembly performance.

[0046] The working principle of the support device for branch conductor measurement in the embodiment of the utility model is as follows:

[0047] The connecting block 31 is inserted into the slide groove 1 along the vertical direction, i.e., parallel to the slide groove 1, and the connecting block 31 is rotated 90 degrees in the slide groove 1 so that the connecting block 31 is parallel to the horizontal plane, i.e., perpendicular to the slide groove 1, so that the connecting block 31 is fixed in the slide groove 1 and does not slide. Then, the connecting rod 32 passes through the through hole 411 on the vertical plate 41, and a nut is tightened at the rear end of the connecting rod 32 to fix the vertical plate 41 on the tunnel segment 2. Since the transverse plate 42 and the side reinforcement plate 5 are fixedly connected to the vertical plate 41 by welding, when the vertical plate 41 is fixed to the tunnel segment 2, the transverse plate 42 and the side reinforcement plate 5 are also fixed to the tunnel segment 2. Then, a measuring instrument can be placed on the transverse plate 42 to complete the measurement.
