Description

Technical Field

[0001] The utility model relates to a railway line spacing measuring instrument, belonging to the technical field of railway line spacing measuring equipment. Background Art

[0002] Track spacing, also known as "track spacing," is the distance between the centerlines of two adjacent tracks (lines). Track spacing is determined based on relevant limits, the technical equipment associated with driving between adjacent lines, and the nature of the operations being handled.

[0003] Railway track spacing includes the spacing between passenger and freight shared tracks and passenger-only tracks, and their sizes should comply with the relevant provisions of the "Railway Technical Management Regulations." The minimum standard track spacing (track spacing) for straight sections of railway sections or station lines can be found in the "Railway Technical Management Regulations." For example, in existing double-track sections, the minimum distance between the centerlines of the two main lines is 4,000mm; the minimum distance between the centerlines of two adjacent arrival and departure tracks within a station is 5,000mm; if both adjacent tracks are used by oversized freight trains and there are high-post signals between the tracks, the track spacing is 5,300mm, etc.

[0004] During the current construction process of railway lines, it is necessary to measure the "track spacing" while installing the lines so that the distance between the center lines of two adjacent tracks (lines) after installation complies with the relevant provisions of the "Railway Technical Management Regulations". Currently available measuring tools generally use rulers or laser measuring instruments for measurement. The use of rulers for measurement places relatively high demands on technical personnel. If the operation is not standardized, there will be certain errors in the measurement results, which will affect the installation and commissioning of the "track spacing". In addition, the labor intensity of using rulers for measurement is also relatively high. Currently available laser measuring instruments, such as the laser measuring instrument and measurement method disclosed in publication number CN101804822A, use a laser transmitter vehicle and a laser receiver vehicle, with a laser transmitter installed on the laser transmitter vehicle and a laser receiver target installed on the laser receiver vehicle. Laser measurement is used to measure the "track spacing" distance. Although this method can measure the distance between the centerlines of two adjacent tracks (lines), it ignores the parallelism error between the two rails in a single track. If there is an error in the parallelism between the two rails in a single track during construction and installation, even if the distance between the centerlines of the two adjacent tracks (lines) can be measured, the value will be inaccurate. Therefore, it is urgent to propose an improved railway track spacing measuring instrument to solve the above-mentioned technical problems. Utility Model Content

However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0021] Specific implementation method 1: Combination Figures 1-6 Describe this embodiment. A railway line spacing measuring instrument according to this embodiment includes a laser emitting vehicle 1 and a laser receiving target vehicle 2. The laser emitting vehicle 1 is provided with a laser 3, and the laser receiving target vehicle 2 is provided with a laser receiving target 4. The structures of the laser emitting vehicle 1 and the laser receiving target vehicle 2 are the same, both including a crossbeam 5 and a longitudinal beam 6. The longitudinal beam 6 has a first running wheel 7. One end of the crossbeam 5 is mounted in conjunction with the longitudinal beam 6, and a measuring wheel assembly 8 is mounted on the other end of the crossbeam 5. The measuring wheel assembly 8 includes a first spring seat 9, a second spring seat 22, an optical axis 10, a first linear bearing seat 11, a second linear bearing seat 12, a running wheel seat 13, a second running wheel 14, a transition beam 15, a bracket 16, a magnetic grating fixing bar 17 and a reading head 18. The first spring seat 9 and the second spring seat 22 are fixedly mounted on the crossbeam 5. Two parallel optical axes 10 are installed on a spring seat 9 and a second spring seat 22. The first linear bearing seat 11 and the second linear bearing seat 12 are installed on the optical axis 10. A spring 25 is installed on the optical axis 10. One end of the spring 25 rests on the second spring seat 22, and the other end of the spring 25 rests on the second linear bearing seat 12. A walking wheel seat 13 is installed at the lower end of the first linear bearing seat 11, and the second walking wheel 14 is rotatably installed on the walking wheel seat 13. The lower end of the second linear bearing seat 12 is installed with the walking wheel seat 13 through a transition beam 15. A bracket 16 is installed on the transition beam 15, and a magnetic grid fixing bar 17 is installed on the bracket 16. A read head 18 is installed on the second spring seat 22. An auxiliary wheel frame 23 is installed at the lower end of the transition beam 15, and an auxiliary walking wheel 24 is installed on the auxiliary wheel frame 23.

[0022] The measuring principle of a railway line spacing measuring instrument in this embodiment is:

[0023] First, the laser transmitting vehicle 1 and the laser receiving target vehicle 2 are placed on two adjacent tracks (lines) respectively, and the laser transmitting vehicle 1 and the laser receiving target vehicle 2 are driven synchronously on the track. The laser receiving target 4 on the laser receiving target vehicle 2 receives the laser signal (track direction, height, verse and other geometric parameters of the track) emitted by the laser 3 on the laser transmitting vehicle 1, and the laser receiving target 4 transmits the signal data to the computer;

[0024] At the same time, the measuring wheel assembly 8 installed on the crossbeam 5 is used to measure the position difference between the two rails in a single track. The specific method is: the second running wheel 14 of the measuring wheel assembly 8 is installed on the rail, and the auxiliary running wheel 24 is fitted with the side wall of the rail. When the crossbeam 5 is pushed normally to walk on the two rails, the second running wheel 14 and the auxiliary running wheel 24 move smoothly. When there is an installation difference between the positions of the two rails, the position of the auxiliary running wheel 24 is offset, and the auxiliary running wheel 24 drives the "first linear bearing seat" through the transition beam 15 and the running wheel seat 13. 11 and the second linear bearing seat 12" move on the optical axis 10, at which time the bracket 16 also moves, and the magnetic grid fixing bar 17 installed on the bracket 16 also moves. The read head 18 reads the displacement change of the magnetic grid fixing bar 17 and transmits the displacement change data to the computer. The displacement data is compared with the standard rail position data to obtain the position difference between the two rails; when the second running wheel 14 and the auxiliary running wheel 24 travel to the standard rail section, they are restored to their normal positions under the action of the restoring force of the spring 25.

[0025] Specific implementation method 2: Combination Figures 1-6 The present embodiment describes a railway line spacing measuring instrument, wherein the crossbeam 5 and the longitudinal beam 6 are installed by bolts or welding. The crossbeam 5 and the longitudinal beam 6 installed by bolts are easy to disassemble during maintenance, while the crossbeam 5 and the longitudinal beam 6 installed by welding will not have position deviation caused by loose bolts during daily use, thereby avoiding the problem of inaccurate measurement data.

[0026] Specific implementation method three: Combination Figures 1-6 This embodiment describes a railway line spacing measuring instrument. A laser mounting bracket 20 is installed on the crossbeam 5 of the laser emitting vehicle 1, and the laser 3 is installed on the laser mounting bracket 20; a laser receiving target mounting bracket 21 is installed on the crossbeam 5 of the laser receiving target vehicle 2, and the laser receiving target 4 is installed on the laser receiving target mounting bracket 21.

[0027] Specific implementation method four: Combination Figures 1-6 The present embodiment is described as a railway line spacing measuring instrument. A handle 26 is installed on the crossbeam 5, and the handle 26 can be used to push the crossbeam 5 to move on the track.

Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutations and combinations. Therefore, the present invention will no longer describe the technical solutions after permutations and combinations one by one, but it should be understood that the technical solutions after permutations and combinations have been disclosed by the present invention.
