Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of large-scale construction surveying equipment, and in particular relates to a large-scale layout tool. Background Technology
[0002] A certain line workshop has nearly 100 kilometers of track construction tasks each year, and the construction period is the busiest time in the workshop. Continuous construction work and night shifts make the personnel working on the large machines quite hard, especially those who are responsible for setting out the tracks before and after the machines. With the number of workshop employees decreasing while the workload of large machines remains the same, improving the efficiency of large machine construction and saving manpower has become particularly important. However, under the current construction conditions of technology and tools, improving efficiency and saving manpower has become a major challenge.
[0003] The existing method for setting out large machinery involves using an L-shaped ruler to measure the height difference of the rail surface before and after the machinery at the setting-out point, and using a 5-meter ruler to measure the lateral displacement of the rail. This is used to calculate whether the machinery's operational effectiveness meets standards. However, the L-shaped ruler is relatively long and bulky, making it inconvenient to set up, and its use in electrified sections is unsafe. Furthermore, both the L-shaped and 5-meter rulers require two workers to operate, meaning that a single large machinery operation requires four workers, putting pressure on manpower allocation.
[0004] Therefore, this solution is an improvement on the existing layout tools. Utility Model Content

[0016] As a further embodiment of this utility model: one end of the bracket is hinged to the mounting base, and the other end is provided with a positioning component. The positioning component has a curved surface that fits with the lower jaw of the rail head. The magnet is built into the positioning component, and one side of the magnet constitutes part of the curved surface.
[0017] As a further embodiment of this utility model: a support portion extends vertically along the bracket, the length of the support portion being adapted to the length of the mounting base, and the nut seat is fixedly connected to the end of the support portion.
[0018] As a further embodiment of this utility model: the support part divides the bracket into two parts, wherein the length of the part with the positioning element is greater than the thickness of the rail head.

[0040] An electronic rangefinder 4 is connected to the mounting base 2. The electronic rangefinder 4 can be an infrared rangefinder, a laser rangefinder, or an ultrasonic rangefinder.
[0041] Specifically:
[0042] See appendix Figure 1 The upper surface of the mounting base 2 is a horizontal plane, the electronic rangefinder 4 is fixedly connected to the upper surface of the mounting base 2, and a level 5 is also provided on the upper surface of the mounting base 2 for leveling.
[0043] See appendix Figure 1 In this embodiment, the adjusting component 3 includes a nut seat 31 and an adjusting bolt 32. The nut seat 31 is fixedly connected to the bracket 1, and the output end of the adjusting bolt 32 abuts against the lower surface of the mounting base 2 (point contact). By rotating the adjusting bolt 32, the mounting base 2 is raised or lowered until the level 5 is leveled.
[0044] Furthermore, a support member 11 is provided laterally at the output end of the adjusting bolt 32 (see...). Figure 3 Alternatively, in option 4), the length of the support member 11 is greater than the diameter of the adjusting bolt 32 but less than the width of the mounting base 2. The support member 11 forms a line contact with the lower surface of the mounting base 2, providing more stable support and facilitating leveling.
[0045] See appendix Figure 1 In this embodiment, a magnet 6 is provided on the bracket 1 so that it can be attached to the rail head, making it easy to pick up and put down the tool.
[0046] Further, see Appendix Figure 1 In this embodiment, one end of the bracket 1 is hinged to the mounting base 2, and the other end is provided with a positioning member 12. The positioning member 12 has a curved surface 13 that fits against the lower jaw of the rail head. The magnet 6 is built into the positioning member 12, and one side of the magnet 6 forms part of the curved surface 13. This structural design facilitates tool adsorption and installation, and is easy to operate.
[0047] Furthermore, a support portion 14 extends vertically along the bracket 1, the length of the support portion 14 being adapted to the length of the mounting base 2, and the nut seat 31 is fixedly connected to the end of the support portion 14.
[0048] The support 14 divides the bracket 1 into two parts, one of which has a positioning member 12 whose length is greater than the thickness of the rail head. The bracket 1 is a one-piece structure, with an overall tilted "T" shape, made of metal, with a simple structure and easy processing.
[0049] Further, see Appendix Figure 1 In this embodiment, a handle 7 is also provided on the bracket 1. The handle 7 is integrally formed with the bracket 1 to form a door handle-like structure. A gripping part 71 is provided on the handle 7. The gripping part 71 can also be covered with an anti-slip sleeve to facilitate the picking up of tools.
[0050] Example 2:
[0051] This utility model discloses a manufacturing process for a large-scale machine layout tool, as follows:
[0052] 1. Prepare relevant components
[0053] An infrared electronic rangefinder with millimeter-level accuracy, a maximum measuring distance of 60 meters, and high measurement accuracy;
[0054] A horizontal bubble tube, high precision;
[0055] 2. Processing and manufacturing related components
[0056] The bracket is machined according to relevant design drawings and is suitable for P60 steel rails. It can be firmly attached to the steel rail.
[0057] The mounting base is machined according to the relevant design drawings and is used to place the electronic rangefinder and the level bubble tube. The levelness of the upper surface of the mounting base is required to be highly accurate.
[0058] The adjustment components are machined according to the relevant design drawings.
[0059] 3. Assemble the above components and conduct a large-scale layout test.
[0060] Example 3:
[0061] This utility model discloses a method for using a large-scale machine layout tool, as detailed below:
[0062] Before the track tamping machine starts operating, attach the layout tool to the rail head at point A.
[0063] Rotate the adjusting bolt to raise or lower the mounting base until the bubble in the horizontal bubble tube is centered, thus completing the leveling process; turn on the infrared electronic rangefinder and record the relevant data.
[0064] After the track leveling machine finishes its work, attach the staking tool to the rail head at point A; rotate the adjusting bolt to raise or lower the mounting seat until the bubble in the horizontal bubble tube is centered, thus completing the leveling; turn on the infrared electronic rangefinder and record the relevant data.
[0065] By comparing the changes in horizontal and vertical distances at target point A before and after the operation, the changes in line displacement after the operation can be determined, and the large machine layout operation can be completed.
[0066] The following comparison is performed by selecting 7 points:
[0067] Traditional layout method: Testers randomly selected 7 points along line W1 at a certain base and used the traditional layout method of an "L"-shaped ruler and a 5-meter measuring tape to measure the height and lateral distance. The number of workers and the duration of the work were summarized and statistically analyzed. The statistical content is as follows:
[0068]
[0069]
[0070] As shown in the table above, the average time for single-point layout is 1.5 minutes, and the number of workers is 2, so a single person cannot complete the layout operation.
[0071] Existing layout method: The testers randomly selected 7 points along line W1 at a certain base, used the new tool to measure the height and lateral distance, and summarized and statistically analyzed the number of workers and the duration of the operation. The statistical content is as follows:
[0072]
[0073] Because the distances of the selected reference points vary, the working time varies considerably, but the working speed has been significantly improved. As shown in the table above, the average time for single-point layout is 30 seconds, and the number of workers is 1, meaning that a single person can complete the layout work.
[0074] Thus, the objective of this utility model has been achieved.
[0075] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
