Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway construction, in particular to a laser track square. Background Art
[0002] The existing method of measuring the misalignment length of the joint welds of the rails on both sides is usually to use a T-square. When in use, the T-square is directly overlapped on the two rails of the line. The right-angle characteristic of the T-square is used to measure whether the sleeper is perpendicular to the line, thereby judging whether the misalignment length of various rail joints meets the specification requirements.
[0003] However, in actual use, the existing T-square is inconvenient to carry due to its large size and length that must be at least greater than the standard track gauge of 1435mm. At the same time, due to the need to consider railway signals, the square ruler must be made of insulating material or insulated to prevent interference with railway signals, which is expensive. In addition, due to the large length of the T-square, it is easy to deform due to improper storage, affecting observation accuracy. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a laser track square in view of the above-mentioned deficiencies in the prior art, which has a relatively light structure, is easy to install and carry, and effectively improves the observation accuracy, and is easy to use and highly practical.
[0005] The technical solution adopted by the utility model is: a laser track square, comprising a horizontal bar, a vertical bar arranged perpendicularly to the horizontal bar is provided in the middle position of the horizontal bar, a holder for mounting a laser pen is provided above the middle position of the horizontal bar, a plurality of light shielding plates are provided on the vertical bar, a laser limiting hole is opened on each of the light shielding plates, and the center line of the laser limiting hole and the center line of the holder are located on the same plane.
[0006] As a further improvement, an arc-shaped groove for placing a laser pen is provided above the card holder.
[0007] Furthermore, there are two shading plates, which are evenly arranged on the vertical rods.
[0008] Furthermore, two positioning plates for locating the placement of the cross bar are provided on the rear side of the cross bar.
[0009] Furthermore, vertical auxiliary lines perpendicular to each other are provided at the center positions of the top surfaces of the horizontal rod and the vertical rod.
[0010] Furthermore, an observation hole for observing the rail joint is provided in the middle of the crossbar.
[0011] Furthermore, both ends of the crossbar are provided with bubble levels for adjusting the level.
[0012] Beneficial effects
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] The utility model discloses a laser track square. When we need to measure the misalignment between the track joints of two rails, we first install the laser pen on the arc groove on the base. Two laser limit holes are used to control the laser path, which can effectively control the propagation path of light and improve the observation accuracy. Then the cross bar is installed on one side of the first rail, and the positioning plate is used for positioning. The level of the bubble level is observed to adjust the cross bar to a horizontal state. Then, the square ruler measuring point is placed on the track joint of the first rail through the observation hole, and the laser pen is turned on to illuminate the second rail on the other side. The position is marked at the laser sighting position, and the distance between the laser sighting position and the center of the track joint of the second rail is measured, so as to quickly calculate the misalignment between the rails and judge whether the misalignment length of the rail joint meets the specification requirements. The device has a relatively light structure and is easy to install and carry. Deformation can be calibrated by two vertical auxiliary lines of the cross bar and the vertical bar. When measuring with laser, the track circuit on the rail will not be connected, and insulation problems can be ignored, which reduces costs. The device has the characteristics of being easy to use and having a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.
[0020] See Figure 1-3As shown, a laser track ruler of the present invention comprises a crossbar 1, a vertical bar 2 arranged perpendicularly thereto is provided in the middle of the crossbar 1, a holder 3 for mounting a laser pen is provided above the middle of the crossbar 1, a plurality of shading plates 5 are provided on the vertical bar 2, each shading plate 5 is provided with a laser limiting hole 10, the center line of the laser limiting hole 10 and the center line of the holder 3 are located on the same plane, when we need to measure the amount of misalignment between the two rails, we first install the laser pen on the arc groove 9 on the holder 3, the two laser limiting holes 10 are used to control the laser path, which can effectively control the propagation path of light and improve the observation accuracy, and then the crossbar 1 is installed on one side of the first rail 11, and the positioning plate 4 is used for positioning , observe the level of the bubble level 8, which is used to adjust the crossbar 1 to a horizontal state, and then place the square ruler measuring point on the rail joint of the first rail 11 through the observation hole 6, turn on the laser pen to illuminate the second rail 12 on the other side, mark the position at the laser aiming position, measure the distance between the laser aiming position and the center of the rail joint of the second rail 12, so as to quickly calculate the rail misalignment, and thus determine whether the rail joint misalignment length meets the specification requirements. This device has a relatively light structure and is easy to install and carry. The two vertical auxiliary lines 7 of the crossbar 1 and the vertical bar 2 can be used to calibrate whether there is deformation; using laser to measure will not connect the track circuit on the rail, and insulation problems can be ignored, reducing costs.
[0021] Specifically, an arc-shaped groove 9 for placing a laser pen is provided above the holder 3, so that the laser pen can be accurately mounted on the vertical auxiliary line 7 to ensure measurement accuracy.
[0022] Preferably, there are two shading plates 5, which are evenly arranged on the vertical rod 2, and adopt the principle of three points in one line, so that the light emitted by the laser pen can accurately hit the second rail 12, thereby improving the observation accuracy.
[0023] Furthermore, two positioning plates 4 for positioning the crossbar 1 are provided on the rear side of the crossbar 1. The positioning plates 4 are close to the sides of the first rail 1 and play a positioning role, making it easier for the crossbar 1 to be clamped on the first rail 11.
[0024] Furthermore, vertical auxiliary lines 7 perpendicular to each other are provided at the center positions of the top surfaces of the horizontal bar 1 and the vertical bar 2. The two vertical auxiliary lines 7 can be used to calibrate whether there is deformation, thereby ensuring measurement accuracy.
[0025] Furthermore, an observation hole 6 for observing the rail joint is provided in the middle of the crossbar 1 , and the measuring point can be accurately placed on the rail joint of the first rail 11 through the observation hole 6 .
[0026] Furthermore, bubble levels 8 for adjusting the level are provided at both ends of the crossbar 1. The level of the bubble level 8 is observed to adjust the crossbar 1 to a horizontal state, making the measurement more accurate.
[0027] When using a laser track ruler of this embodiment, the laser pen is first installed on the arc groove 9 on the holder 3. The two laser limit holes 10 are used to control the laser path, which can effectively control the propagation path of light and improve the observation accuracy. Then the cross bar 1 is installed on one side of the first rail 11, and the positioning plate 4 is used for positioning. The level of the bubble level 8 is observed to adjust the cross bar 1 to a horizontal state. Then, the ruler measuring point is placed on the rail joint of the first rail 11 through the observation hole 6, and the laser pen is turned on to illuminate the second rail 12 on the other side. The position is marked at the laser aiming position, and the distance between the laser aiming position and the center of the rail joint of the second rail 12 is measured, so as to quickly calculate the rail misalignment and judge whether the rail joint misalignment length meets the specification requirements. The device has a relatively light structure and is easy to install and carry. The two vertical auxiliary lines 7 of the cross bar 1 and the vertical bar 2 can be used to calibrate whether there is deformation. When measuring with laser, the track circuit on the rail will not be connected, and insulation problems can be ignored, thereby reducing costs. The laser track square ruler of the utility model has a relatively light structure, is easy to install and carry, effectively improves the observation accuracy, and has the characteristics of being easy to use and highly practical.
