[technical field]

The utility model relates to a measuring tool for rails, in particular to a measuring ruler related to rail construction inclination states.

[Background technique]

At present, in my country's rail engineering, although there are requirements for the inclination of the rail, there are no mature detection tools and detection methods. Most of the existing detection methods are through a detection ruler made into a standard 1/40 slope or flat slope. The surface slope of the iron backing plate is compared. There are many defects in this detection method: when the iron backing plate is suspended, the measurement result will be wrong; The inclination of the rail; in addition, when the flat surface of the iron backing plate is not enough, the detection method will fail.

A spirit level, which is a hollow square tube. The top and bottom surfaces of the square tube near both ends are provided with elongated holes through which the two legs of the measuring base pass. The square tube is also provided with gaps near the top surfaces of both ends. The pipe is provided with a cover plate at the position of the gap to form a groove matching the guide rail. The vertical rods of the two legs of the measuring base are located in the gap on the corresponding side of the square tube, and the guide rails of the vernier sleeve are located in the groove. Inside, the lower ends of the springs are clamped in the square tube wall at the position of the elongated hole on the bottom surface.

Further, the rail inclination measuring ruler also has the following optimized structure:

The level is provided with a handle.

The measuring head is a hemisphere.

Compared with the prior art, the utility model has the following advantages:

1. No need to use other tools, the height difference of the rail bottom can be directly measured by measuring the outrigger, and then the inclination of the rail can be obtained.

2. The movable outrigger design is applicable to various types of rails and rail inclinations required by various designs.

3. Directly measure the bottom of the rail, regardless of the type of the rail head or the type of the backing plate of the fastener, the measurement flexibility is enhanced, and the measurement data is accurate.

4. Set the distance between each pair of hemispherical probes to a fixed value through the limit rod, and quickly read the value of the inclination of the rail without calculation.

[detailed description]

In order to make the purpose, principle and structure of the present utility model clearer, further elaboration will be made below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments and drawings are only for explanation and not for limiting the protection scope of the present utility model. The descriptions of orientations in the embodiments are all relative positions, not absolute positions.

The rail construction inclination state detection ruler structure of the present embodiment is as follows:

As shown in Figure 1, it includes two measuring bases, and each measuring base includes two opposite legs. The "relative" described in this embodiment can refer to Figures 1, 3, 4 or 5, and the upper part of the legs is The vertical rod part, the lower part of the leg is a horizontal rod part, the lower end of the vertical rod part is connected with the outer end of the horizontal rod part to form an L-shaped structure, and the lower parts of the two L-shaped parts point to the other leg. The upper surface of the inner end of the cross bar has a protruding hemispherical probe, and the two opposite legs are formed by their respective cross bar and vertical bar to form a hollow pincer structure with the inner end of the bottom horizontal bar facing each other. The upper part of the rod part has a height scale, the middle part of the vertical rod part is provided with a spring stopper, the spring is set under the spring stopper of the cross bar part, the upper end of the spring is fixed on the spring stopper, and the height scale is covered with a vernier sleeve. The vernier sleeve is provided with a scale window, and a magnifying glass is arranged on the window. The vernier can slide up and down along the scale, and the scale is read in the window to form a structure similar to a vernier caliper. This is clear to those skilled in the art. The lower end of the leg is provided with a horizontal raised track, and the top of one of the legs is provided with a horizontal limit rod.

The spirit level is a hollow bar with a handle on its top. In this embodiment, a hollow square tube is used, but of course other bars with similar structures can also be used. There is a gap vertically penetrating near the two ends of the rod. A cover plate is provided on the rod wall at the gap position. There is a groove matching the track between the rod wall and the cover plate. The vertical rods of the two legs of the measuring base The part is located in the gap on the corresponding side of the rod, the track of the cursor sleeve is located in the groove, and the lower ends of the springs are clamped on the inner surface of the rod wall at the lower end of the gap.

The following is the method of using the rail construction inclination state detection ruler in this embodiment.

1. Slide the outer legs of the two measuring bases to the sides, and the inner legs to the inner side to open the legs.

2. Put the level tube in the middle of the left and right rails, and the paired legs on both sides stand on both sides of the rail in the shape of a clamp.

3. Press the "L"-shaped outriggers in pairs and draw them towards both sides of the rail. When each pair of "L"-shaped outriggers is close to the limit rod, slowly let go. The rebound of the shaped strut makes the bottom hemispherical probe bear against the bottom of the rail. As shown in Figure 4.

4. Read the readings on each pair of measuring legs, and calculate the difference, and divide the difference by the distance between each pair of hemispherical probes to get the rail inclination. For example: set the distance between each pair of hemispherical probes to 120mm through the limit rod, and when the height difference is 3mm, the rail bottom slope is 1/40.
