Description

Technical Field

[0001] This utility model belongs to the field of railway facility inspection tools, specifically relating to a device for detecting the verticality of sleepers on straight sections. Background Technology

[0002] With the rapid development of my country's economy, infrastructure projects have increased significantly. Railways, as the main artery of the national economy, are a crucial national infrastructure and a popular mode of transportation. Although ballastless track has developed rapidly, the scale of ballasted track projects remains substantial. Due to site conditions, construction investment, and line size, some lines cannot be laid mechanically, and manual track laying is required in most cases. On straight sections of the line, the main task of the sleeper laying process in manual track laying is to adjust the perpendicularity of the sleepers to the rails to ensure that the track's geometric dimensions meet design and specification requirements.

[0003] During railway operation, the track structure is repeatedly affected by train loads, and the sleepers are displaced to varying degrees. The traditional inspection tools used by the inspection personnel cannot measure the specific offset angle, and it is impossible to form an accurate inspection record, which cannot effectively guide the workers to carry out maintenance and adjustment. Utility Model Content

[0004] This invention aims to solve the problem that it is inconvenient for track patrol personnel to detect the specific offset angle of sleepers on straight sections.

[0005] This utility model provides the following technical solution: a device for detecting the verticality of sleepers on straight sections, comprising a straight ruler, a horizontal rod, and a dial; the straight ruler has a straight edge, the horizontal rod is fixed to the top surface of the straight ruler, the horizontal rod is perpendicular to the straight edge of the straight ruler, the bottom surface of the horizontal rod is a plane, the length of the horizontal rod is greater than the spacing of the rails, and both ends of the horizontal rod extend outward relative to the straight edge of the straight ruler so that both ends of the horizontal rod can rest on the top surface of the rails; the dial is connected to the straight ruler, and the dial is provided with angle scale lines, the origin of which is located at the intersection of the straight edge of the horizontal rod and the straight ruler.

[0006] Furthermore, it also includes a pointer, the axis of which is located at the origin of the dial.

[0007] Furthermore, the straightedge is a straight rod.

[0008] Furthermore, the dial is an arc-shaped ring, with both ends of the arc-shaped ring connected to a ruler; the pointer's pivot is mounted on the ruler, and the pointer is located on the bottom surface of the dial.

[0009] Furthermore, a laser pointer is mounted at the bottom of the pointer, with the laser beam aligned with the pointer's direction of indication.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] This invention provides a device for detecting the verticality of railway sleepers on straight sections. It accurately detects the vertical offset angle between the sleeper and the rail, significantly improving the construction quality of manually laid sleepers, reducing rework rates, and facilitating track operation and maintenance. The data collected by this device can better guide workers in sleeper maintenance and repair. This detection device is characterized by its simple structure, ease of manufacture, accurate positioning, and high precision. Attached Figure Description

[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] like Figure 1 As shown: A device for detecting the verticality of sleepers on straight sections includes a straight ruler 1, a horizontal rod 2, and a dial 3. The straight ruler 1 has a straight edge, and the horizontal rod 2 is fixed to the top surface of the straight ruler 1. The horizontal rod 2 is perpendicular to the straight edge of the straight ruler 1, and the bottom surface of the horizontal rod 2 is a plane. The length of the horizontal rod 2 is greater than the spacing between the rails, and both ends of the horizontal rod 2 extend outward relative to the straight edge of the straight ruler 1 so that both ends of the horizontal rod 2 can rest on the top surface of the rails. The dial 3 is connected to the straight ruler 1, and the dial 3 is provided with angle scale lines. The origin of the angle scale lines is located at the intersection of the straight edge of the horizontal rod 2 and the straight ruler 1.

[0017] It also includes pointer 4, whose axis of rotation is located at the origin of dial 3.

[0018] The straightedge 1 is also a straight rod. The horizontal straight rod 2 and the straightedge 1 are made of rectangular steel pipes and are welded together. The center line of the straightedge 1 is perpendicular to the center line of the horizontal straight rod 2. The specifications of the rectangular steel pipe should be 60*40*1.5mm, the length of the straightedge 1 should be 50cm, and the length of the horizontal straight rod 2 should be 2.6m.

[0019] The dial 3 is an arc-shaped ring, with both ends connected to the straightedge 1; the pivot of the pointer 4 is mounted on the straightedge 1, and the pointer 4 is located on the bottom surface of the dial 3. The dial 3 is made of 1.0mm thick stainless steel plate, with an inner diameter of 20cm and an outer diameter of 25cm; the two ends of the dial 3 are fixed to the straightedge 1 by welding.

[0020] A laser pointer is installed at the bottom of pointer 4, and the direction of the laser pointer is aligned with the direction of pointer 4; the laser pointer extends the pointing distance of pointer 4, making it easier for pointer 4 to be aligned with sleeper 5.

[0021] The steps for using a device for detecting the verticality of sleepers on a straight section according to this embodiment are as follows:

[0022] Step 1: During manual track laying, after the sleeper and track laying processes are completed, proceed with the sleeper laying process. Place the straightedge 1 against the inner edge of the rail 6, ensuring the straightedge 1 and rail 6 are in close contact and parallel.

[0023] Step 2: Since the centerline of the straightedge 1 is perpendicular to the centerline of the horizontal bar 2, the centerline of the horizontal bar 2 is the theoretical centerline 8 of the sleeper. If the theoretical centerline 8 of the sleeper does not coincide with the actual centerline 7 of the sleeper, it proves that the sleeper 5 is not perpendicular to the rail 6 and there is an angular deviation, requiring adjustment of the perpendicularity of the sleeper 5. Starting from the theoretical centerline 8 of the sleeper, rotate the pointer 4 clockwise or counterclockwise to the actual centerline 7 of the sleeper, read the offset angle from the scale 3, with leftward deviation being negative and rightward deviation being positive, and record it.

[0024] Step 3: Adjust the vertical angle of the sleeper according to the specific offset angle so that its centerline coincides with the centerline 8 of the theoretical position.

[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
