Description

Technical Field

[0001] This utility model belongs to the field of railway track spacing measurement technology, and in particular relates to a railway construction sleeper track spacing measurement device. Background Technology

[0002] During the construction of the sleeper rail system or during subsequent maintenance, it is necessary to periodically measure the sleeper spacing (the distance between sleepers in a railway track). In traditional measurements, a steel tape measure is often used for convenience. The steps are as follows: Select a reference sleeper on the track (such as the sleeper at the starting point), align the zero mark of the tape measure with one edge of the sleeper (usually to measure the center-to-center distance of sleepers, the center position of the sleeper can be marked first); stretch the tape measure along the track direction and read the scale value at the corresponding position of the next sleeper, which is the distance between the two sleepers; repeat the measurement for multiple sets of data (such as measuring once every 10 sleepers), record the maximum value, minimum value, and average value, and evaluate the uniformity of the spacing.

[0003] However, existing measurement methods often suffer from deviations in the steel measuring tape, leading to tilting and significant measurement errors that can affect subsequent maintenance. To address this, we propose a railway sleeper spacing measurement device that avoids measurement deviations and resolves the shortcomings of existing methods. Utility Model Content

[0004] The purpose of this invention is to provide a railway sleeper spacing measuring device that avoids measurement deviation and thus improves measurement accuracy, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A railway construction sleeper spacing measuring device includes a limiting support frame, the number of the limiting support frames is two, a slide rail is fixedly connected between the two limiting support frames, a sliding seat is slidably connected to the surface of the slide rail, a limiting plate one is fixedly connected to the bottom of the sliding seat, an adjustable limiting plate two is slidably arranged at the bottom of the limiting plate one, a scale plate is fixedly connected to the top of the slide rail, an indicator plate is fixedly connected to the top of the sliding seat, a threaded rod is threadedly connected to the bottom of the inner cavity of the limiting support frame, and a limiting handle is fixedly connected to the opposite side of the threaded rod.

[0006] Preferably, the first limiting plate, the second limiting plate, and the indicator plate are located on the same vertical axis.

[0007] Preferably, the slide rail is an I-shaped slide rail, and the inner surface of the slide rail is slidably connected to the outer surface of the slide seat.

[0008] Preferably, a connecting rod is fixedly connected to both the front and rear positions of the top of the second limiting plate, and the outer surface of the connecting rod is provided with multiple threaded holes.

[0009] Preferably, the connecting rod slides through the inner surface of the limiting plate, and the inner surface of the threaded hole is threaded with a limiting bolt, which passes through the limiting plate and extends to the outer side of the limiting plate.

[0010] Preferably, the surface of the scale plate is provided with scale lines.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a threaded rod that rotates on the inner surface of a limiting support frame, thereby moving a limiting handle to limit and fix both sides of the sleeper rail. Then, a sliding seat slides on the inner surface of the slide rail, simultaneously moving the limiting plate one at the bottom of the sliding seat and the indicator plate at the top. The limiting plate one moves the limiting plate two, causing the limiting plate two to fit against the side of the sleeper rail. The indicator plate slides to the corresponding scale line, thereby measuring the distance between the sleepers rail. By setting the above structure, measurement offset can be avoided, thereby improving measurement accuracy and avoiding large measurement errors.

[0013] 2. This utility model sets the slide rail as an I-shaped slide rail, and the inner surface of the slide rail is slidably connected to the outer surface of the sliding seat, so that the sliding seat is moved and supported at the same time.

[0014] 3. This utility model has multiple threaded holes, and the inner surfaces of the multiple threaded holes are connected with limit bolts, so that the vertical distance between the limit plate one and the limit plate two can be adjusted, thereby fitting different positions on the surface of the sleeper rail according to the situation.

[0015] 4. This utility model has scale lines on the surface of the scale plate, which makes it easier for the measuring personnel to observe. Attached Figure Description

[0023] In the following description, embodiments of the railway construction sleeper spacing measuring device of the present invention will be described with reference to the accompanying drawings.

[0024] Example 1:

[0025] Figure 1-4 This invention illustrates a railway sleeper spacing measuring device according to an embodiment of the present invention. It includes two limiting support frames 1, with a slide rail 2 fixedly connected between them. A sliding seat 3 is slidably connected to the surface of the slide rail 2. The slide rail 2 is an I-shaped slide rail, and its inner surface is slidably connected to the outer surface of the sliding seat 3. By setting the slide rail 2 as an I-shaped slide rail and its inner surface to the outer surface of the sliding seat 3, the sliding seat 3 is supported while being moved. A limiting plate 4 is fixedly connected to the bottom of the sliding seat 3, and an adjustable limiting plate 5 is slidably arranged at the bottom of the limiting plate 4. A scale plate 6 is fixedly connected to the top of the slide rail 2, and scale lines are provided on the surface of the scale plate 6. The scale lines on the surface of the scale plate 6 facilitate observation by the measuring personnel. The top of the sliding seat 3 is fixedly connected to... The indicator plate 7, limit plate one 4, limit plate two 5, and indicator plate 7 are located on the same vertical axis. The bottom of the inner cavity of the limit support frame 1 is threadedly connected to a threaded rod 8. A limit handle 9 is fixedly connected to the opposite side of the threaded rod 8. The threaded rod 8 rotates threadedly on the inner surface of the limit support frame 1, thereby driving the limit handle 9 to move. The limit handle 9 limits and fixes both sides of the sleeper rail. Then, the sliding seat 3 slides on the inner surface of the slide rail 2, simultaneously driving the limit plate one 4 at the bottom of the sliding seat 3 and the indicator plate 7 at the top to move. The limit plate one 4 drives the limit plate two 5 to move, so that the limit plate two 5 fits against the side of the sleeper rail. The indicator plate 7 slides to the corresponding scale line, thereby measuring the distance between the sleepers rail. By setting the above structure, measurement offset can be avoided, thereby improving the measurement accuracy and avoiding large measurement errors.

[0026] Example 2:

[0027] Figure 1-4This invention illustrates a railway sleeper spacing measuring device according to an embodiment of the present invention. It includes two limiting support frames 1, with a slide rail 2 fixedly connected between them. A sliding seat 3 is slidably connected to the surface of the slide rail 2. A limiting plate 4 is fixedly connected to the bottom of the sliding seat 3. An adjustable limiting plate 5 is slidably disposed at the bottom of the limiting plate 4. Connecting rods 10 are fixedly connected to the front and rear positions of the top of the limiting plate 5. Multiple threaded holes 11 are formed on the outer surface of the connecting rods 10. The connecting rods 10 slide through the inner surface of the limiting plate 4, and the inner surface of the threaded holes 11... A threaded connection is provided with a limiting bolt 12, which penetrates the limiting plate 4 and extends to the outside of the limiting plate 4. By providing multiple threaded holes 11, and threaded connection of the limiting bolt 12 to the inner surface of the multiple threaded holes 11, the vertical distance between the limiting plate 4 and the limiting plate 5 can be adjusted, thereby fitting different positions on the surface of the sleeper rail as needed. A scale plate 6 is fixedly connected to the top of the slide rail 2, and an indicator plate 7 is fixedly connected to the top of the slide seat 3. A threaded rod 8 is threadedly connected to the bottom of the inner cavity of the limiting support frame 1, and a limiting handle 9 is fixedly connected to the opposite side of the threaded rod 8.

[0028] Working Principle: In use, the threaded rod 8 rotates threadedly on the inner surface of the limiting support frame 1, thereby driving the limiting handle 9 to move. The limiting handle 9 limits and fixes both sides of the sleeper rail. Then, the sliding seat 3 slides on the inner surface of the slide rail 2, simultaneously driving the limiting plate 4 at the bottom and the indicator plate 7 at the top of the sliding seat 3 to move. The limiting plate 4 drives the limiting plate 5 to move, so that the limiting plate 5 fits against the side of the sleeper rail. The indicator plate 7 slides to the corresponding scale line, thereby measuring the distance between the sleepers rail. By setting multiple threaded holes 11, and the inner surface of multiple threaded holes 11 is threaded with limiting bolts 12, the vertical distance between the limiting plate 4 and the limiting plate 5 can be adjusted. This allows for fitting at different positions on the sleeper rail surface as needed, thereby avoiding measurement deviation and improving measurement accuracy, thus avoiding large measurement errors.
