Description

Technical Field

[0001] The utility model relates to the technical field of track gauge monitoring, and more specifically, to a device for track gauge monitoring. Background Art

[0002] In recent years, with the continuous development of my country's economic construction, rail transit construction has also made great achievements, and the rail transit network has continued to expand. Safety is the most basic requirement for railway transportation production. Railway gauge monitoring is of great significance in the safety and maintenance of railway tracks.

[0003] The traditional method of track gauge monitoring relies on manual measurement with manpower and track gauges. This method can be used for non-enclosed rail transit with small vehicle volume. However, for rail transit with large vehicle volume and frequent trains, the use of manual measurement methods will pose a great threat to the safety of measurement personnel. In addition, for enclosed rail transit, it is difficult for inspection personnel to enter the track area for measurement, which brings great inconvenience to the monitoring work. Summary of the invention

[0004] The utility model provides a track gauge monitoring device for monitoring the distance of railway tracks, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A track gauge monitoring device comprises two rail clamps, a connecting rod, a detection substrate and a displacement sensor. The two rail clamps are respectively connected to two rails of a railway track. One end of the connecting rod is fixedly connected to one of the rail clamps, and the other end is slidably connected to the other rail clamp. The detection substrate is arranged at the sliding end of the connecting rod, and the displacement sensor is arranged on the rail clamp corresponding to the sliding end of the connecting rod. Through the cooperation of the displacement sensor and the detection substrate, the displacement change of the detection substrate is monitored to realize the monitoring of the track gauge between the two rails.

[0007] Preferably, a sliding sleeve is fixed to the sliding end of the connecting rod on the corresponding rail card, the sliding end of the connecting rod is slidably connected to the rail card through the sliding sleeve, and the displacement sensor is fixed on the sliding sleeve.

[0008] Further preferably, an insulating section is provided on the connecting rod.

[0009] The detection substrate is made of insulating material.

[0010] The displacement sensor is fixed on the sliding sleeve through a sensor bracket.

[0011] The sensor bracket is a part made of insulating material.

[0012] The beneficial effects achieved by the utility model compared with the prior art are:

[0013] The utility model adopts a rail clip to suspend the monitoring device at the bottom of the rail, thereby effectively avoiding the influence on driving, and realizes the connection between the two rails through a connecting rod, so that the change of the distance between the rails is converted into the sliding change of the connecting rod, and then through the cooperation of a fixed position displacement sensor and a detection substrate that moves with the connecting rod, the change of the track gauge is converted into the displacement change of the detection substrate, so that the displacement change of the detection substrate is monitored by the displacement sensor, and the track gauge between the two rails is monitored.

[0014] The sliding connection between the connecting rod and the corresponding rail card is realized through the sliding sleeve, which greatly facilitates the installation and fixation of the displacement sensor. By setting an insulating section on the connecting rod and using a detection substrate and sensor bracket made of insulating material, the short circuit between the rails and the electrical connection between the sensor and the rail are effectively avoided, which effectively guarantees and improves the stability and reliability of the sensor, making the monitoring structure accurate, stable and reliable.

[0015] The utility model has the characteristics of simple structure, low cost, convenient installation and maintenance, strong practicability and good use effect, and is worthy of wide promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. The program systems involved or relied upon in the following embodiments are conventional programs or simple programs in the technical field, and those skilled in the art can make conventional choices or adaptive adjustments according to specific application scenarios.

Example

[0019] See also Figure 1 and 2A track gauge monitoring device includes two rail cards 2, a connecting rod 3, a detection substrate 4 and a displacement sensor 5. The two rail cards 2 are respectively connected to the bottom of two steel rails 1 of the railway track. One end of the connecting rod 3 is fixedly connected to one of the rail cards 2, and the other end is slidably connected to the other rail card 2. In this embodiment, the connecting rod 3 includes a connecting section 1 31, a connecting section 2 32, a connecting section 3 33 and a connecting section 4 34, wherein the connecting section 2 32 is an insulating section, which adopts a polymer insulating rod, and the connecting section 4 34 is a sliding section, which is slidably connected with a sliding sleeve 6 provided on the corresponding rail card 2. The sliding sleeve 6 and the connecting section 1 31 are both penetrated on the two rail cards 2, and fixedly connected with the corresponding rail card 2 by positioning nuts 7 on both sides of the rail card 2.

[0020] The detection substrate 4 is arranged at the sliding end of the connecting rod 3. In this embodiment, the sliding sleeve 6 passes through the corresponding rail card 2 and extends a certain distance. The connecting section 4 34 of the connecting rod 3 passes through the sliding sleeve 6 and extends a certain distance. The detection substrate 4 made of insulating material is fixed to the extended end of the connecting section 4 34 through the positioning nuts on both sides thereof. The displacement sensor 5 is fixed to the sliding sleeve 6 through the sensor bracket 8. The displacement sensor 5 is fixedly connected to the sensor bracket 8 made of insulating material. The sensor bracket 8 is fixed to the sliding sleeve 6 through the positioning nuts on both sides thereof. In this embodiment, the displacement sensor 5 adopts an electronic ruler, which is a pull rod type linear displacement sensor. The pull rod end is fixedly connected to the detection substrate 4. The displacement sensor 5 is electrically connected to the power supply system, the data analysis system and the data processing system through the line.

[0021] During operation, when the distance between the two steel rails 1 of the railway track changes, the connecting rod 3 and the sliding sleeve 6 are driven to have relative displacement, so that the detection substrate 4 drives the pull rod of the displacement sensor 5 to move, and then the displacement sensor 5 senses and measures the change in the track gauge through the movement of the pull rod, thereby realizing the coordination between the displacement sensor 5 and the detection substrate 4, monitoring the displacement change of the detection substrate 4 through the displacement sensor 5, realizing the monitoring of the track gauge between the two steel rails 1, and uploading the monitoring data to the data analysis system and the data processing system.

[0022] In this embodiment, the power supply system, data analysis system and data processing system are all prior art, which are only used as examples and to express the integrity of the technical solution. The displacement sensor 5 of the utility model can also adopt other types of displacement sensors to realize displacement monitoring, and adopt built-in power supply and wireless communication and other prior art technologies to realize wireless deployment and remote data transmission. The displacement sensor 5 can also be fixed directly to the corresponding rail card 2 through a bracket instead of the sliding sleeve 6. Therefore, it should be explained at the end that the described embodiments are only part of the embodiments of the utility model, not all of them. All equivalent changes made according to the structure, shape and principle of this application, and all other embodiments obtained by ordinary technicians in this field without creative work, should be covered within the scope of protection of this application.
