Description

Technical Field

[0001] This utility model relates to the field of ground magnetic sensor detection technology, specifically to a ground magnetic sensor detection device. Background Technology

[0002] Currently, electric locomotives pass through an automatic phase-change system during operation. This system uses ground magnetic sensors installed at both ends of the sleepers and a magnetic induction device installed at the bottom of the locomotive. When the magnetic induction device detects the ground magnetic sensor during operation, the locomotive switches to phase, thus enabling automatic phase-change.

[0003] Because the ground magnetic sensors on the sleepers may be damaged or lost due to wear, impact or high temperature during actual use, the electric locomotive may not be able to react in time and effectively to switch phases when it approaches the ground magnetic sensors. This can cause the electric locomotive to break through the phase while energized, resulting in a pantograph-catenary accident, which seriously affects train operation and transportation safety.

[0004] Currently, there is a portable ground magnetic sensor detection device used to measure the magnetic flux on railway sleepers and determine whether the ground magnetic sensor on the sleepers meets the usage requirements. For example, Chinese utility model patent with publication number CN215728747U provides a static detection device for cross-phase ground magnetic flux that is easy to measure manually by hand, which facilitates the measurement of magnetic flux on railway sleepers.

[0005] However, the railway tracks are far apart and the track environment is complex, making the measurement work difficult for staff. At the same time, the measurement work is affected by factors such as weather, which increases the difficulty and safety of the work. The measurement frequency cannot be guaranteed, so the safe operation of electric locomotives cannot be fully guaranteed. Utility Model Content

[0006] The purpose of this invention is to provide a ground magnetic sensor detection device to solve the problem of high difficulty in detecting and measuring ground magnetic sensors.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A ground magnetic sensor detection device includes a detection vehicle, a positioning device, and multiple magnetic sensor detectors. The detection vehicle is equipped with track wheels at its bottom. The multiple magnetic sensor detectors are arranged on opposite sides of the detection vehicle along its direction of travel, with the magnetic sensor detectors located outside the track wheels. The positioning device is mounted on the detection vehicle.

[0009] Furthermore, the magnetic induction detector is connected to the bottom of the detection vehicle via a foreign object removal mechanism.

[0010] Further specifying, the foreign object removal mechanism includes a horizontal connecting block, a vertical connecting rod, and a foreign object cleaning component. One end of the horizontal connecting block is connected to the bottom of the detection vehicle, the foreign object cleaning component is disposed at the other end of the horizontal connecting block, the vertical connecting rod is connected to the horizontal connecting block, the vertical connecting rod is located between the detection vehicle and the foreign object cleaning component, and the magnetic induction detector is connected to the bottom of the vertical connecting rod.

[0011] Furthermore, the foreign object cleaning component is a brush.

[0012] Furthermore, the ground magnetic sensor detection equipment also includes an audible and visual alarm device, which is installed on the detection vehicle and is communicatively connected to the magnetic sensor detector.

[0013] Furthermore, the ground magnetic sensor detection equipment also includes a display terminal, which is installed inside the detection vehicle. The audible and visual alarm device, the magnetic sensor detector, and the positioning device are all communicatively connected to the display terminal.

[0014] Further specifying, the positioning device includes a positioning antenna and a positioning module, wherein the positioning antenna is communicatively connected to the display terminal through the positioning module.

[0015] Furthermore, the magnetic induction detector is connected to the display terminal via an RS485 communication interface.

[0016] Furthermore, the ground magnetic sensor detection equipment also includes a storage terminal, which is installed inside the detection vehicle and is communicatively connected to the magnetic sensor detector and the positioning device.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by placing a magnetic induction detector on the inspection vehicle, allows the operator to control the vehicle's movement from the driver's cab during sleeper inspection. The results from the magnetic induction detector determine whether the ground magnetic inductance on the sleeper meets usage requirements. The structure is simple and reduces measurement difficulty, thereby increasing measurement reliability by increasing the measurement frequency. Furthermore, the addition of a positioning device records the location of problematic sleepers, enabling repairs to be carried out one by one according to the recorded locations after magnetic flux measurement, thus improving work efficiency.

[0019] 2. This utility model connects the magnetic induction detector to the inspection vehicle through a foreign object removal mechanism, so that the magnetic induction detector can remove foreign objects on the sleeper in a timely manner during the inspection, avoiding damage to the magnetic induction detector or affecting its detection accuracy, so that the actual use meets the inspection requirements.

[0020] 3.

This notifies the driver to record the current location in a timely manner, thus recording the location of the faulty sleeper for subsequent maintenance or secondary inspection.

[0021] 4. By setting up a display terminal and a storage terminal on the testing vehicle, this utility model can display the measurement results of the magnetic induction detector and the positioning results of the positioning device, making it convenient for the driver to view and record. On the other hand, it can also store the obtained measurement results and positioning results for later playback and verification. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] refer to Figure 1 This embodiment provides a ground magnetic sensor detection device, including a detection vehicle 1, a positioning device 2 and multiple magnetic sensor detectors 3. The bottom of the detection vehicle 1 is equipped with track wheels 4. The detection vehicle 1 can move on the track by driving the track wheels 4, so that the staff can work at night or in rainy or snowy weather, while ensuring work safety, reducing work difficulty, improving work efficiency and meeting work requirements.

[0028] The positioning device 2 is installed on the inspection vehicle 1, preferably on the top of the inspection vehicle 1. The positioning device 2 is used to display the real-time position of the inspection vehicle 1. The magnetic induction detector 3 is installed on the bottom of the inspection vehicle 1. It is used to perform magnetic induction detection on the sleeper above the position of the ground magnetic sensor during the operation of the inspection vehicle 1 and display the detection results. Therefore, the magnetic induction detector 3 is installed on the side of the inspection vehicle 1 and is located outside the track wheel 4. Since the installation position of the ground magnetic sensor on the sleeper is uniform, the installation position of the magnetic induction detector 3 can remain unchanged.

[0029] Furthermore, since the ground magnetic sensors on the sleepers are installed at opposite ends of the sleepers, the number of magnetic induction detectors 3 can be selected as two, and the two magnetic induction detectors 3 can be symmetrically arranged. In order to improve the accurate detection of the magnetic flux of the ground magnetic sensors, it is preferable that the number of magnetic induction detectors 3 on one side of the detection vehicle 1 is at least two, for example, it can be set as three. The three magnetic induction detectors 3 are equally spaced on the same side of the detection vehicle 1 along the direction of travel of the detection vehicle 1. The magnetic induction detectors 3 on both sides of the detection vehicle 1 can be symmetrically arranged or staggered, which increases the effective detection of the sleepers and improves the detection accuracy.

[0030] At this time, when the ground magnetic sensor on the sleeper malfunctions or is lost, the magnetic induction detector 3 near the front of the inspection vehicle 1 detects that the magnetic flux is less than the set value. At this time, it can be confirmed by the second magnetic induction detector 3. If the measured value is still less than the set value, the current position is recorded by the positioning device 2. If the detection result of the second magnetic induction detector 3 is greater than the set value, then the detection result of the third magnetic induction detector 3 can be used for judgment. That is, regardless of whether the detection result of the third magnetic induction detector 3 is the same as the detection result of the first magnetic induction detector 3 or the detection result of the second magnetic induction detector 3, the detection result of the third magnetic induction detector 3 shall be used as the standard.

[0031] To improve the driver's ability to record faulty ground magnetic sensors in a timely manner, an audible and visual alarm device 6 is installed in the inspection vehicle 1. The audible and visual alarm device 6 is connected to the magnetic induction detector 3. When the measurement result of the magnetic induction detector 3 is less than the set value, the audible and visual alarm device 6 is activated to trigger an audible and visual alarm, thereby reminding the driver to record the fault in a timely manner.

[0032] The inspection vehicle 1 is preferably equipped with a display terminal 7. The magnetic induction detector 3 and the positioning device 2 are both connected to the display terminal 7. The display terminal 7 is used to display the detection results of the magnetic induction detector 3 and the positioning results of the positioning device 2 on the display terminal 7, so as to facilitate viewing and recording. At the same time, the audible and visual alarm device 6 is also connected to the display terminal 7, so that the audible and visual alarm device 6 can also display and remind you when it is working. The magnetic induction detector 3 is connected to the display terminal 7 through an RS485 communication interface.

[0033] To further explain, a storage terminal 8 is also installed on the inspection vehicle 1. The storage terminal 8 is connected to the magnetic induction detector 3 and the positioning device 2 respectively. It is used to record and store all the detection results of the magnetic induction detector 3 and the real-time position information of the positioning device 2. In this way, when reviewing the data, the location of sleeper faults that were not recorded in time or were missed can be found, thereby further improving the accuracy and reliability of the inspection and reducing the difficulty of the inspection.

[0034] To further explain, since there may be stones, iron filings or other foreign objects on the sleepers on the outer side of the track, on the one hand, it will affect the detection results of the magnetic induction detector 3, and on the other hand, it will cause the magnetic induction detector 3, which moves with the detection vehicle 1, to be damaged after collision, increasing the cost of maintenance and replacement, and also affecting the accuracy of measurement.

[0035] Specifically, a foreign object cleaning device can be installed at the head of the inspection vehicle 1, so that it can clean the foreign objects on the sleepers during the operation of the inspection vehicle 1, thereby ensuring that the magnetic induction detector 3 is not obstructed by foreign objects when passing over the sleepers, thus improving the accuracy and reliability of the detection.

[0036] The magnetic induction detector 3 can also be connected to the bottom of the detection vehicle 1 through the foreign object removal mechanism 5, thereby reducing the size of the foreign object removal mechanism 5 and reducing the cost of use; the foreign object removal mechanism 5 can remove foreign objects between the magnetic induction detector 3 and the sleeper, thereby ensuring the accuracy and reliability of the detection.

[0037] refer to Figure 2 Specifically, the foreign object removal mechanism 5 includes a horizontal connecting block a, a vertical connecting rod b, and a foreign object cleaning component c. One end of the horizontal connecting block a is connected to the bottom of the inspection vehicle 1, and the other end of the horizontal connecting block a is connected to the foreign object cleaning component c. The foreign object cleaning component c can extend from the bottom of the horizontal connecting block a to the upper surface of the sleeper. The vertical connecting rod b is connected to the middle position of the horizontal connecting block a. The magnetic induction detector 3 is installed at the bottom end of the vertical connecting rod b, so that the magnetic induction detector 3 is located between the inspection vehicle 1 and the foreign object cleaning component c.

[0038] Therefore, in actual use, the foreign object cleaning component c can follow the movement of the detection vehicle 1 to remove foreign objects on the sleeper in front of the magnetic induction detector 3, thereby ensuring that the detection of the magnetic induction detector 3 is accurate and reliable and meets the usage requirements.

[0039] The foreign object cleaning component C can be selected as an air blowing device to disperse foreign objects on the sleeper, or it can be selected as a rotary cleaning structure to remove foreign objects from the sleeper; see reference. Figure 3 The foreign object cleaning component c can be a brush, which can be a triangular structure with the apex of the brush facing the direction of travel of the inspection vehicle 1. The vertical connecting rod b and the magnetic induction detector 3 are located in the middle of the brush, so that the foreign objects on the sleeper are cleaned as the brush follows the inspection vehicle 1, thereby ensuring the accurate and reliable detection of the magnetic induction detector 3. The structure is simple and low in cost, meeting the usage requirements.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
