Description

Technical Field

[0001] This utility model belongs to the technical field of railway ultra-high strength concrete sound barrier installation, specifically relating to a special inspection tool for railway sound barrier installation. Background Technology

[0002] When installing ultra-high strength concrete sound barriers for railways, it is necessary to ensure a verticality of 0.2% and that the gap between adjacent railway sound barriers is within 16mm. However, there is currently no tooling specifically designed for checking the gaps during railway sound barrier installation. The only option is to use a measuring tape to check the gap spacing. But because a single measurement is prone to inaccuracy, at least two measurements are required for each gap to determine whether the verticality of the railway sound barrier and the gap width meet the standards. This process is cumbersome and prone to human measurement errors. If an error is not corrected in time, the adjustment process after installation is troublesome. It is also possible that an error will lead to the same substandard installation of railway sound barriers in subsequent installations, resulting in poor noise reduction effect and far-reaching consequences. Utility Model Content

[0003] This utility model aims to provide a special inspection tool for railway sound barrier installation. It is simple to operate and accurate in measurement, solving the problem that using a measuring tape to check the gap spacing requires at least two measurements for each gap, which leads to cumbersome operation and a high possibility of data error.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a special inspection fixture for railway sound barrier installation. The inspection fixture has a symmetrical structure in both the left and right sides and the front and back. The front and rear ends of the inspection fixture are provided with portal frames. The tops of the two portal frames are connected in the middle by a reinforcing connecting rod. The legs on the same side of the two portal frames are connected by crossbars to form a slot frame that clamps the corresponding side columns of the adjacent railway sound barrier.

[0005] As a preferred option of the above scheme, the inspection fixture is welded from 3cm x 3cm stainless steel, which is reasonable in material selection and has a stable structure.

[0006] A further preferred embodiment is that the dimensions of the portal frame are 193mm~196mm inner width × 9cm~10cm inner height, which is a reasonable size.

[0007] Further preferably, the length of the crossbar is 1m to 1.1m, which is a reasonable size, and the verticality of the railway sound barrier is checked at the same time as the gap width is checked.

[0008] Further preferably, the inspection fixture is equipped with a level and a plumb line, which is reasonably designed to ensure the accuracy of data measurement.

[0009] A further preferred embodiment is that the side columns of the railway sound barrier are 9cm wide, which is a reasonable size.

[0010] The beneficial effects of this utility model are as follows: Compared to methods that require measuring the gap spacing with a tape measure and taking at least two measurements for each gap, this application uses a special inspection tool for railway sound barrier installation. Based on the definition of a straight line determined by two points, the tool only needs to be inserted into the corresponding side column of the adjacent railway sound barrier to measure the distance between the two straight lines accurately. This eliminates the need for multiple measurements; a single measurement can detect the parallelism of the corresponding side columns and the gap width of adjacent railway sound barriers. The operation is simple, fully ensuring that the railway sound barrier installation meets standards. If any defects are found during the installation process, the barrier can be directly readjusted to meet the requirements, allowing for timely adjustments and avoiding more troublesome subsequent corrections.

[0011] This utility model has the advantages of simple one-time measurement operation, accurate detection, and full guarantee that the installation of railway sound barriers meets the standards. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0014] like Figure 1 As shown, a special inspection tool for railway sound barrier installation is provided. The inspection tool has a symmetrical structure on both the left and right sides and front and back. The front and rear ends of the inspection tool are equipped with gantry frames 1.

[0015] The tops of the two portal frames 1 are centered and connected by a reinforcing connecting rod 3.

[0016] The legs on the same side of the two portal frames 1 are connected by crossbars 2 to form a slot frame that locks the corresponding side columns of the adjacent railway sound barrier.

[0017] The inspection fixtures are preferably made of 3cm x 3cm stainless steel welded together.

[0018] The preferred dimensions for the gantry frame 1 are an inner width of 193mm to 196mm and an inner height of 9cm to 10cm.

[0019] The length of the crossbar 2 is preferably 1m to 1.1m.

[0020] The inspection equipment is equipped with a spirit level and a plumb line.

[0021] The width of the side columns of the railway sound barrier is preferably 9cm.

[0022] The width of the side columns of the railway ultra-high strength concrete sound barrier is generally 9cm, and the gap between adjacent railway sound barrier side columns is no more than 16mm. Therefore, the two columns plus the gap are no more than 196mm. The dimensions of the portal frame 1 are 196mm inner width × 9cm inner height.

[0023] Insert the inspection fixture into the side columns of the two adjacent railway sound barriers that have been installed, and use a level and plumb line to assist in the verification of the plumbness.

[0024] If the inspection tool can be inserted into the column, and the column's verticality meets the standard of 0.2% when combined with the level and plumb line, then the installation of the two railway sound barriers is qualified.

[0025] If it fails to meet the requirements, the installed railway sound barrier needs to be adjusted until it meets the requirements.

[0026] By defining a straight line by two points, the distance between two straight lines can be measured simply by inserting the tool into the corresponding side column of the adjacent railway sound barrier. The concept is ingenious and the design is novel.
