Description

Technical Field

[0001] The utility model relates to the technical field of track rulers, in particular to a push track ruler. Background Art

[0002] The track gauge (track gauge) is a special measuring instrument used to measure the gauge between two rails on a railway line. The track gauge can be divided into a mechanical scale gauge and a digital gauge. The digital gauge can automatically complete the measurement of all data, completely eliminating the cumbersome operating procedures of bending over to adjust the degree wheel, aligning the level bubble to zero, looking at the superelevation scale, and then looking at the gauge scale from just above the magnifying glass scale when using a mechanical scale gauge. It reduces the labor intensity of the operator, shortens the measurement time, and improves the work efficiency. Straight-line measurement improves efficiency by 40%, curve measurement improves efficiency by 60%, and curve measurement in tunnels improves efficiency by more than double. Therefore, most of the existing track gauges are digital gauges.

[0003] The current model is GJC-HTS0WD, a portable push gauge, which is upgraded from a high-precision static portable gauge to a pushable structure product. It is mainly used to detect the gauge, level and superelevation and other geometric parameters of standard gauge lines. The data is effectively analyzed and managed through the software system. The product has fast measurement speed and easy operation. It can be used during daytime and nighttime. It is used by engineering maintenance, large-scale measurement and other relevant departments for line operations.

[0004] This product has a foldable push handle. When in use, unfold the push handle and use it to push the track ruler along the railway track. The display end at the top of the crossbar displays the measurement results. However, this product is like other similar products. Since the display end at the top of the crossbar is far away from the standing operator, it is difficult for the operator to see the measurement results on the display end when standing, which can easily lead to misreading. Therefore, it is best to squat down to see the measurement results. It is not convenient to use and has certain disadvantages.

[0005] Therefore, it is necessary to provide a track ruler to solve the above technical problems. Utility Model Content

When using the push rod 5 to push the device to move on the track for measurement, the measurement data can be viewed at close range by watching the sub-display screen 6 close to the human body, so it is not easy to misread the data, and there is no need to squat to see the main display screen, thereby making the use of the device more convenient. When in use, hold the end of the push rod 5 and push the cross bar 1 to move on the track, stop when it moves to the position to be measured, and the fixed end 2 and the movable measuring end 3 are stuck on the inner side of the track. The measuring body 4 measures the data of the track and displays the measured results on the measuring body 4 and the sub-display screen 6. The user can view the measurement data by watching the sub-display screen 6 nearby, without squatting to view the displayed data on the measuring body 4, thereby making the use of the device more convenient. Since the screen of the sub-display screen 6 is larger, it is more difficult to misread the data.

[0032] By installing a fixed end 2, a movable measuring end 3, a measuring body 4, a push rod 5 and a sub-display screen 6 on a cross bar 1, the push rod 5 is used to push the device to move along a track to measure the track, and the measurement result is displayed through the sub-display screen 6 which is closer to the human body and has a larger size, thereby improving the convenience of using the device and reducing the possibility of misreading data. Example 2

[0033] like Figure 2 and Figure 5 As shown, two horizontal support wheels 7 and two side positioning wheels 8 are installed at the bottom of the fixed end 2 and the movable measuring end 3. The horizontal support wheels 7 are in contact with the top of the track, and the side positioning wheels 8 are in contact with the inner side of the track. The fixed end 2 and the movable measuring end 3 are supported and positioned by the horizontal support wheels 7 and the side positioning wheels 8, so that the device can move and measure on the track.

[0034] By providing the horizontal support wheels 7 and the side positioning wheels 8, the track ruler can be conveniently moved and measured on the track. Example 3

[0035] like Figure 1-4 As shown, a track frame 9 is slidably installed on the cross bar 1, and the track frame 9 can move along the length direction of the cross bar 1. The bottom of the track frame 9 is connected to the top of the movable measuring end 3. A measuring rod 10 is installed on the top of the cross bar 1. The measuring rod 10 passes through the track frame 9. A spring 11 is installed on the measuring rod 10.

The measuring head 21 is used to measure the distance between it and the measuring rod 10. The measuring head 21 is electrically connected to the measuring body 4. When in use, the side positioning wheel 8 of the movable measuring end 3 is stuck on the inner side of the track, so that the spring 11 is in a compressed state. The measuring head 21 measures the distance between it and the end of the measuring rod 10 and transmits the data to the measuring body 4. The measuring body 4 compares the initial zero position data set, and then calculates the rule and displays the result.

[0036] By providing the track frame 9, the measuring rod 10 and the spring 11, the movable measuring end 3 can be elastically slidably connected to the cross bar 1. The measuring head 21 is used to measure the distance change between it and the end of the measuring rod 10, thereby indirectly determining the track gauge value. Example 4

[0037] like Figure 5-6As shown, the first mounting frame 12 and the second mounting frame 13 are plugged and installed on the fixed end 2, and limit screws are installed on the sides thereof to fix them. The horizontal support wheel 7 is installed at the bottom of the first mounting frame 12, and the side positioning wheel 8 is installed at the bottom of the second mounting frame 13. The horizontal support wheel 7 and the side positioning wheel 8 at the bottom of the movable measuring end 3 are installed in the same way. When the horizontal support wheel 7 and the side positioning wheel 8 need to be replaced, unscrew the limit screws installed on the sides of the two, and the first mounting frame 12 and the second mounting frame 13 can be replaced together with the first mounting frame 12, the second mounting frame 13, the horizontal support wheel 7, and the side positioning wheel 8, so that the replacement is quicker and more convenient.

[0038] By providing the first mounting frame 12 and the second mounting frame 13 , the horizontal support wheel 7 and the side positioning wheel 8 can be supported, so that the horizontal support wheel 7 and the side positioning wheel 8 can be replaced conveniently. Example 5

When replacing the side positioning wheels 8, the correction plate (straight plate) is overlapped on one side of the two side positioning wheels 8, and the left and right positions of the second mounting frame 13 are adjusted so that the side of the positioning plate 19 is just parallel and close to the side of the correction plate. At this time, the tangent of the two side positioning wheels 8 is perpendicular to the length direction of the cross bar 1 (if the two are not perpendicular, the cross bar 1 is not perpendicular to the track, and the measured track gauge is inaccurate), and then the limit screw can be tightened to fix the second mounting frame 13.

[0040] By providing a positioning plate 19 at the bottom of the fixed end 2 and using the positioning plate 19 to position the side positioning wheel 8, the installation position of the side positioning wheel 8 is more precise, and the measured track gauge data is more accurate. Example 6

[0041] like Figure 6-7 As shown, the fixed end 2 and the movable end 3 have the same structure, and a plug hole 14 and a positioning groove 16 are provided on the fixed end 2. A plug connector 15 and a positioning block 17, as well as a screw hole 18 for installing a limit screw, are installed on the first mounting frame 12 and the second mounting frame 13. During installation, the plug connector 15 and the positioning block 17 are respectively aligned with the plug hole 14 and the positioning groove 16 and inserted, so that the first mounting frame 12 and the second mounting frame 13 are plugged with the fixed end 2 (movable end 3), and the limit screw is screwed into the screw hole 18 so that one end of the limit screw is pressed tightly against the side of the fixed end 2 (movable end 3), thereby fixing the first mounting frame 12 and the second mounting frame 13.

[0042] The first mounting frame 12 , the second mounting frame 13 and the fixed end 2 are plugged into each other by providing the plugging hole 14 , the plugging joint 15 , the positioning groove 16 and the positioning block 17 . Example 7

[0043] like Figure 3 As shown, a snap-in groove 20 is provided in the middle of the cross bar 1, and a snap joint is installed at the end of the push rod 5. The snap joint is snap-fitted with the snap-in groove 20, so that the push rod 5 is snap-fitted with the cross bar 1. The push rod 5 can be removed and the device can be used as an ordinary digital track gauge, so that the device can be used according to different usage environments, thereby improving the practicability of the device.

[0044] By providing the clamping groove 20, the push rod 5 can be easily removed, and the device can be used as a common digital track gauge, thereby improving the practicability of the device.

[0045] Working principle: When in use, hold the end of the push rod 5, push the cross bar 1 to move on the track, stop when it moves to the position to be measured, the fixed end 2 and the movable measuring end 3 are stuck on the inner side of the track, the measuring body 4 measures the data of the track, and displays the measured results on the measuring body 4 and the auxiliary display screen 6. The user can view the measurement data by watching the auxiliary display screen 6 nearby, without squatting to view the displayed data on the measuring body 4, thereby making the use of the device more convenient. Since the screen of the auxiliary display screen 6 is larger, it is less likely to read the data incorrectly.
