Abstract
Description
Technical Field
[0001] This utility model relates to the field of overhead contact line inspection technology for high-speed trains, specifically to a tooling for measuring the horizontal and vertical spacing of overhead contact line wires. Background Technology
[0002] During routine maintenance of the overhead contact system, in accordance with comprehensive maintenance requirements, it is necessary to measure relevant safety distances. For example, in a fully compensated catenary suspension, the vertical distance between the catenary and the contact wire should be 200mm to 300mm, and the projections of the catenary and the contact wire on the horizontal plane must coincide, with a maximum allowable deviation of no more than 150mm. If there is a crossing, the spacing between the crossing catenary should be ≥100mm. In special scenarios such as anchor joints and line switches, the distance between the non-support contact wire and the working support positioning pipe should be ≥50mm, and the distance with the reverse positioning inclined wire should be ≥100mm. Therefore, currently, all stations and sections use a spirit level and measuring tape for this type of work.
[0003] Specifically, a level needs to be set horizontally near the contact wire as a measurement reference. Based on this reference, the horizontal or vertical distance of the wire is measured using a ruler. Since the level and measuring tape are separate, a single person cannot simultaneously set the level and pull the measuring tape. Therefore, two people are generally required for the inspection. However, for the catenary cable, both people need to climb to a height such as the catenary arm to take the measurement, which results in low work efficiency.
[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Summary of the Invention
[0005] To address the aforementioned technical deficiencies, the present invention provides a tooling for measuring the horizontal and vertical spacing of contact wires, comprising a measuring tape and a level. The measuring tape is fixedly mounted at the end of the level, with the tape's opening perpendicular to the level. The level is provided with a vertical horizontal post and a horizontal horizontal post.

The first connecting segment and the second connecting segment are rotatably connected by a first hinge, and the second connecting segment and the third connecting segment are rotatably connected by a second hinge.
[0008] Preferably, the first hinge and the second hinge are respectively disposed at both ends of the second connecting segment, and the first hinge and the second hinge are respectively disposed on both sides of the second connecting segment.

[0010] Preferably, the measuring tape is fixedly installed at the end of the first connecting segment away from the second connecting segment, and an electronic level is installed on the third connecting segment, the electronic level being able to detect the tilt angle of the level.
[0011] Preferably, a laser rangefinder is fixedly installed at the end of the third connecting segment away from the second connecting segment.

Detailed Implementation
[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings. Example 1
[0023] like Figures 1 to 4 As shown, Figure 1 A perspective view of the unfolded structure of the fixture used to measure the horizontal and vertical spacing of the contact wires; Figure 2 This is a three-dimensional structural view of the tooling used to measure the horizontal and vertical spacing of the contact wire during the folding process. Figure 3 This is a top view of the tooling used to measure the horizontal and vertical spacing of the contact wires in its unfolded state. Figure 4 This is a top view of the fixture used to measure the horizontal and vertical spacing of the contact wires in its folded state.
[0024] The tooling for measuring the horizontal and vertical spacing of contact wires according to this utility model includes a measuring tape 1 and a level 2. The measuring tape 1 is fixedly installed at the end of the level 2, and the direction of the tape opening of the measuring tape 1 is perpendicular to the level 2. The level 2 is provided with a vertical horizontal column 3 and a horizontal horizontal column 4. The vertical horizontal column 3 is used to realize the horizontal setting of the level 2, and the horizontal horizontal column 4 is used to realize the vertical setting of the level 2.
[0025] Specifically, the level 2 includes a first connecting segment 21, a second connecting segment 22, and a third connecting segment 23 arranged sequentially along a straight line. The first connecting segment 21 is connected by the second connecting segment 22 and the third connecting segment 23. The arrangement direction of the first connecting segment 21, the second connecting segment 22, and the third connecting segment 23 is consistent with the extension direction of the level 2. The first connecting segment 21 and the second connecting segment 22 are rotatably connected by a first hinge 24, and the second connecting segment 22 and the third connecting segment 23 are rotatably connected by a second hinge 25, thereby realizing the folding and unfolding of the level 2 in the extension direction, so as to facilitate the carrying and use of this utility model.
[0026] Generally, the measuring strip inside the measuring tape 1 is fixedly connected to a fixed hook 11 at the end of the tape opening. The fixed hook 11 is a J-shaped plate, which is convenient to hook and fix with the line to be measured.
[0027] Preferably, the first hinge 24 and the second hinge 25 are respectively disposed at both ends of the second connecting segment 22, and the first hinge 24 and the second hinge 25 are respectively disposed on both sides of the second connecting segment 22, so that in the folded state, the first connecting segment 21 and the third connecting segment 23 can contact and fit against both sides of the second connecting segment 22, so as to ensure that the level ruler 2 has a small volume when folded.
[0028] Both ends of the second connecting segment 22 are embedded with a first magnetic block 26, and the ends of the first connecting segment 21 and the third connecting segment 23 are embedded with a second magnetic block 27. The first magnetic block 26 and the second magnetic block 27 are arranged correspondingly. When the horizontal ruler 2 is unfolded, the first magnetic block 26 and the corresponding second magnetic block 27 are magnetically attracted to each other, thereby ensuring the stability of the unfolded state of the horizontal ruler 2.
[0029] Generally, the measuring tape 1 is fixedly installed at the end of the first connecting segment 21 away from the second connecting segment 22, and an electronic level 5 is installed on the third connecting segment 23. The electronic level 5 can detect the tilt angle of the level ruler 2, thereby detecting the slope of the positioner and the tilt of the support on the contact network through the level ruler 2. A laser rangefinder 6 is fixedly installed at the end of the third connecting segment 23 away from the second connecting segment 22. The laser rangefinder 6 is used to measure the side clearance and span of the support on the contact network. The folded and unfolded states of the level ruler 2 have no impact on the use of the electronic level 5 and the laser rangefinder 6. At the same time, the folded and unfolded states of the level ruler 2 also facilitate the adjustment of the length of the level ruler 2 based on the actual situation for end face erection to realize the detection and use of the electronic level 5.
[0030] With the structural design of this utility model, single-person measurement can be achieved. That is, one hand holds the level ruler 2 and sets the level ruler 2 horizontally or vertically through the vertical horizontal column 3 or the horizontal horizontal column 4, while the other hand pulls the end of the measuring tape 1 to measure the corresponding distance, which effectively improves work efficiency and facilitates size inspection. Example 2
[0031] The second connecting section 22 is provided with a through groove 28, which extends linearly along the extension direction of the second connecting section 22. The through groove 28 can reduce the weight of the level ruler 2, making it easier to carry. The level ruler 2 can be made of hollow aluminum alloy plate or plastic plate, which can further reduce the overall weight.
[0032] A first connecting block 29 is provided on the first connecting segment 21, and a second connecting block 30 is provided on the third connecting segment 23. The first connecting block 29 and the second connecting block 30 are respectively provided on both sides of the horizontal ruler 2 in the unfolded state, and both the first connecting block 29 and the second connecting block 30 are provided corresponding to the through groove 28. The width of the first connecting block 29 and the second connecting block 30 perpendicular to the extension direction of the horizontal ruler 2 is matched with the groove width of the through groove 28. In the folded state of the horizontal ruler 2, the first connecting block 29 and the second connecting block 30 are both provided in the through groove 28, thereby ensuring the stability of the folded state of the horizontal ruler 2 and ensuring the accuracy of the detection when the horizontal ruler 2 is in the folded state.
[0033] Preferably, the top width of the first connecting block 29 and the second connecting block 30 gradually decreases in the direction away from the horizontal ruler 2, thereby facilitating the alignment of the first connecting block 29 and the second connecting block 30 in the passage slot 28 during the folding process.
[0034] A fall arrestor can be connected to the level ruler 2. The fall arrestor can be fastened to the line to prevent the present invention from falling from a height.
[0035] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
