Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a laser type coupler height rapid measuring device. Background Art

[0002] Railway freight car couplers are vehicle components that connect locomotives and carriages, used to transmit traction and impact forces while maintaining a certain distance between carriages to pass through curves. The reason why railway freight car couplers need to be measured in height is to ensure the safety of railway transportation and the accurate transportation of goods. Coupler height is an important parameter for connecting railway freight cars between locomotives and carriages, and it is directly related to the stability and safety of train operation. It is very important to keep the coupler height within the appropriate range, because a coupler that is too high may cause excessive pressure on the connection, increasing the risk of uncoupling; while a coupler that is too low may cause a loose connection between the carriage and the locomotive, which is also prone to uncoupling accidents. Therefore, accurate measurement and adjustment of coupler height is one of the basic requirements to ensure railway transportation safety.

[0003] In the existing technology, coupler height gauges are not only heavy and inconvenient to carry online, but can only measure the center height of the coupler when the vehicle is uncoupled. There is no effective tool to determine the height difference of the coupler center when the vehicle is coupled. Therefore, we propose a laser-type coupler height rapid measurement device to solve the above problems. Utility Model Content

The top of the sleeper is fixedly connected to two steel rails. The tops of the two steel rails are sleeved with the same horizontal rod. The top of the horizontal rod is provided with a measuring mechanism.

[0007] Preferably, the measuring mechanism includes a laser rangefinder, the top of the horizontal rod is magnetically connected to a magnetic placement sleeve, the inner wall of the magnetic placement sleeve is slidably connected to the outer wall of the laser rangefinder, and the distance between the horizontal rod and the magnetic laser receiving plate is measured by setting the measuring mechanism.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Depend on Figure 1-Figure 3 As shown, a laser-type coupler height rapid measurement device is involved, including a coupler body 1 and a sleeper 2. The outer wall of the coupler body 1 is provided with a coupler center line. The outer wall of the coupler body 1 is magnetically connected to a magnetic laser receiving plate 3. The magnetic laser receiving plate 3 is adsorbed and installed on the coupler body 1 and horizontally aligned with the coupler center line through a positioning scale line 5.

[0021] An anti-loss connection hole 4 is provided on the outer wall of the magnetic laser receiving plate 3, and a steel wire rope is slidably installed on the inner wall of the anti-loss connection hole 4. The magnetic laser receiving plate 3 is connected to the horizontal rod 7 through the steel wire rope, mainly to prevent the magnetic laser receiving plate 3 from being lost.

[0022] The outer wall of the magnetic laser receiving plate 3 is provided with a positioning scale line 5. Two steel rails 6 are fixedly connected to the top of the sleeper 2. The sleeper 2 supports the rails 6. The top of the two rails 6 is sleeved with the same horizontal rod 7, and the outer wall of the horizontal rod 7 is installed with a level bubble.

[0023] A measuring mechanism is provided at the top of the horizontal rod 7, which includes a laser rangefinder 9. The laser rangefinder 9 is an instrument that uses laser to accurately measure the distance to the target. When working, the laser rangefinder 9 emits a very thin beam of laser toward the target. The laser beam reflected by the target is received by the photoelectric element. The timer measures the time from the emission to the reception of the laser beam and calculates the distance to the target. A display is provided on the outer wall of the laser rangefinder 9 to display the measurement data.

[0024] The top of the horizontal rod 7 is magnetically connected to a magnetic placement sleeve 8. The magnetic placement sleeve 8 can move on the horizontal rod 7, driving the laser rangefinder 9 to move and adjust its position so that it is located below the magnetic laser receiving plate 3. The inner wall of the magnetic placement sleeve 8 is slidingly connected to the outer wall of the laser rangefinder 9. The horizontal rod 7 and the magnetic placement sleeve 8 support the laser rangefinder body 9, and the laser rangefinder 9 is located below the magnetic laser receiving plate 3.

[0025] Working principle: During measurement, the magnetic laser receiving plate 3 is adsorbed and installed on the coupler body 1 so that its positioning scale line 5 is aligned with the center line of the coupler. The horizontal rod 7 is placed on the two rails 6. The laser rangefinder 9 is magnetically installed on the top of the horizontal rod 7 through the magnetic placement sleeve 8. The installation position of the laser rangefinder 9 can be adjusted horizontally according to the installation position of the magnetic laser receiving plate 3. After the installation is completed, the distance between the horizontal rod 7 and the magnetic laser receiving plate 3 is measured by the laser rangefinder 9, which is the center height value of the coupler body 1, thereby providing data guidance for the adjustment of the coupler coupling difference. In addition, in order to prevent the magnetic laser receiving plate 3 from being forgotten to be removed or lost, causing driving safety risks, it can be tied to the horizontal rod 7 through a steel wire rope using the anti-lost connection hole 4 on it.
