Description

Technical Field

[0001] The present application relates to the field of rail transportation technology, and in particular to a turnout travel measuring ruler. Background Art

[0002] Turnouts are crucial line connections in rail transit, allowing rolling stock to switch from one track to another. Switches are crucial components of turnout mechanisms, used to change the position of turnouts, alter their opening direction, and lock the switch points. Before rails are put into use, they must be inspected to ensure safe train travel. This inspection typically involves a measuring ruler, such as the utility model disclosed in China, entitled "Turnout Inspection Tool" (application number CN201921700284.X). The measuring ruler comprises a measuring ruler, a first test plate, and a second test plate. One end of the measuring ruler is provided with a right-angle bend, and the other end is movably connected to the first and second test plates arranged side by side. The lower portions of the first and second test plates are thinner than the upper portions. The inner side of the first test plate abuts the outer side of the rail. The second test plate is then pulled so that its inner sidewall abuts the other outer side of the rail, thereby measuring the rail width. However, rail inspections not only involve measuring rail width but also the degree of wear. The tool for measuring rail width is then replaced with a tool for measuring rail wear. This process slows down the inspection process and requires the operator to carry multiple tools, increasing the burden on the operator. Utility Model Content

[0003] The purpose of the utility model is to provide a turnout travel measuring ruler in view of the defects and shortcomings of the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The first measuring device is located on the first bracket. The second measuring device comprises a second electronic measuring instrument and a second ruler. The second electronic measuring instrument is located on the second bracket. The second ruler is placed vertically. The side wall of the second ruler has a standard line. The lower end of the second ruler passes through the second electronic measuring instrument and the second bracket in sequence.

[0006] Preferably, the second measuring device further comprises a mounting frame, the second electronic measuring instrument is mounted and fixed on the mounting frame, and the lower end of the second ruler passes through the second electronic measuring instrument and the mounting frame in sequence.

[0007] Preferably, a mounting plate is provided on one side of the upper end of the mounting frame, and a plurality of mounting holes are vertically and evenly opened on the side wall of the mounting plate, and the second electronic measuring instrument is installed and fixed by screws passing through two of the mounting holes.

[0008] Preferably, a clamping block is installed at the lower end of the first bracket and the lower end of the second bracket, and the two clamping blocks are arranged corresponding to each other.

[0009] Preferably, a first magnetic block is embedded and fixed on the inner side wall of the clamping block.

[0010] Preferably, the outer side walls of the first bracket and the second bracket are respectively provided with handles.

One end of the first ruler is arranged on the end of the second bracket close to the first bracket, and the other end of the first ruler passes through the first electronic measuring instrument.

[0012] Preferably, a second magnetic block is embedded and fixed on the inner side walls of the first bracket and the second bracket respectively.

[0013] In summary, the beneficial technical effects of this application are:

[0014] When it is necessary to inspect the track of the turnout, the second bracket is pulled to move the first bracket and the second bracket away from each other, and the first electronic measuring instrument slides on the first ruler. Then, the second magnetic block on the inner side of the first bracket is adsorbed on the outer side of the track, and the second magnetic block on the inner side of the second bracket is adsorbed on the other outer side of the track. Then, the reading of the first electronic measuring instrument is read, thereby completing the width inspection of the track. Then, the handle on the outer side of the second bracket is held to move the clamping block close to the side wall of the bottom of the track. Then, the first magnetic block is adsorbed on the side wall of the bottom of the track, so that the second bracket is stably located on the track. Then, the second electronic measuring instrument is aligned with the standard line of the second ruler. After pressing the zero key of the second electronic measuring instrument, the second ruler moves downward in the second electronic measuring instrument until the lower end of the second ruler abuts against the upper end surface of the track. Then, the reading of the second electronic measuring instrument is read, so that the degree of wear of the track can be determined. From the above description, it can be seen that the measuring ruler can detect the width and wear degree of the track, thereby improving the work efficiency of track inspection.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The embodiment of the present application discloses a switch travel measuring ruler.

[0021] Reference Figure 1 and Figure 2 , including a first measuring device 1, a second measuring device 2, a first bracket 3 and a second bracket 4. The first measuring device 1 is located on the first bracket 3, the second measuring device 2 is located on the second bracket 4, the vertical sections of the first bracket 3 and the second bracket 4 are respectively in an "L" shape, and the first bracket 3 and the second bracket 4 are symmetrically arranged.

[0022] The first measuring device 1 comprises a first electronic measuring instrument 5 and a first ruler 6. An extension plate is integrally mounted on the sidewall of one end of the first electronic measuring instrument 5, secured to the upper end surface of the first bracket 3 via screws. One end of the first ruler 6 is secured to the upper end surface of the inner end of the second bracket 4 via screws. The other end of the first ruler 6 slides through the first electronic measuring instrument 5. As the first bracket 3 and the second bracket 4 move away from each other, the first electronic measuring instrument 5 slides on the first ruler 6, bringing the inner side of the first bracket 3 into contact with the outer side of the track, while the inner side of the second bracket 4 contacts the other outer side of the track. The first electronic measuring instrument 5 then reads the track width, completing the track width measurement.

[0023] Reference Figure 3The second measuring device 2 includes a mounting bracket 7, a second electronic measuring instrument 8, and a second ruler 9. The upper end surface of the second bracket 4 is provided with a plug-in hole, and the mounting bracket 7 is plugged and fixed in the plug-in hole. A mounting plate 10 is vertically and integrally provided on one side of the upper end of the mounting bracket 7. Six mounting holes 11 are evenly provided on the side wall of the mounting plate 10. The second electronic measuring instrument 8 is fixed in the second electronic measuring instrument 8 by two screws passing through two adjacent mounting holes 11, so that the second electronic measuring instrument 8 is installed on the mounting plate 10. The second ruler 9 is placed vertically, and the lower end of the second ruler 9 passes through the second electronic measuring instrument 8 and the mounting bracket 7 in sequence, and passes through the lower end surface of the second bracket 4. A standard line 12 is horizontally provided on the side wall of the second ruler 9. When checking the degree of wear of the track, the second ruler 9 is first moved within the second electronic measuring instrument 8 to align the standard line 12 with the upper end of the second electronic measuring instrument 8. The zero key of the second electronic measuring instrument 8 is then pressed. The second ruler 9 is then moved downward within the second electronic measuring instrument 8 until the lower end of the second ruler 9 abuts the upper end surface of the track. The reading of the second electronic measuring instrument 8 is then taken to determine the degree of wear of the track.

[0024] Reference Figure 1 and Figure 2 A cylindrical second magnetic block 13 is embedded and fixed to the inner sidewalls of the first bracket 3 and the second bracket 4. When the measuring ruler is measuring the width of the track, the attraction of the second magnetic block 13 keeps the first bracket 3 or the second bracket 4 in stable contact with the track.

[0025] Clamping blocks 14 are bolted to the lower ends of the first and second brackets 3 and 4, respectively. These two clamping blocks 14 are symmetrically arranged, and their inner walls are defined by trapezoidal grooves, within which a first magnetic block 15 is slidably secured. When the measuring ruler is used to inspect the wear of the track, the first magnetic block 15 attracts the inner walls of the clamping blocks 14, keeping them in close contact with the sidewalls of the track bottom.

[0026] The outer side walls of the first bracket 3 and the second bracket 4 are respectively threadedly fixed with handles 16. When operating the measuring ruler, the staff can move the measuring ruler through the handles 16.

[0027] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
