Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically to a lifting test device for a railway locomotive signal receiving coil. Background Technology

[0002] In railway transportation systems, locomotive signal receiving coils are core components ensuring safe train operation, and their performance directly affects the accuracy and reliability of signal reception. Among these, the installation height of the receiving coil is a key factor influencing signal reception quality, directly and significantly impacting signal strength, coupling efficiency, stability, and performance under complex environmental conditions. If the installation position is too low, the receiving coil may be too close to the track surface, making it susceptible to interference from metal debris, track wear, or dirt, thus reducing signal clarity and stability. It may also be damaged when encountering obstacles, affecting signal reception functionality. Conversely, if the installation position is too high, it may weaken the electromagnetic coupling between the coil and the track, significantly reducing the received signal strength. This affects signal recognition and interpretation, causing the train to fail to respond to control commands promptly, increasing the risk of misjudgments and missed judgments, and potentially leading to safety accidents. Furthermore, the optimal installation height ensures maximum coupling efficiency, allowing signals to be accurately transmitted from the track to the receiving coil and then utilized by the train control system. Therefore, precisely controlling the installation height of the receiving coil is crucial for improving the accuracy and reliability of signal reception.

[0003] The locomotive signaling equipment testing system is mainly used to simulate and test the code reception of locomotive signal receiving coils and reproduce operational scenarios, using ground-based code-generating equipment to simulate the on-site code-generating environment. However, existing locomotive signaling equipment testing systems have many shortcomings during the testing process and are difficult to meet the needs of actual maintenance and management.

[0004] Firstly, in existing locomotive signaling equipment testing systems, locomotive signal receiving coils come in two types: long poles and short poles. These are typically placed on the ground for testing, rather than actually installed on the vehicle. This testing method cannot realistically simulate the working state of the receiving coil in a real operating environment, especially failing to accurately reflect the performance of the receiving coil in receiving ground signals at different heights. Therefore, the test results often deviate significantly from reality and are difficult to use as a reliable basis for equipment maintenance and troubleshooting.

[0005] Secondly, existing locomotive signaling equipment testing systems lack intuitiveness and interactivity, hindering employees' in-depth understanding and mastery of the working principles of locomotive signaling equipment. During training, the inability to visually demonstrate the equipment's operating status and malfunctions limits the effectiveness of training and makes it difficult to effectively improve the professional skills of maintenance personnel.

[0006] Therefore, how to provide a lifting test device for railway locomotive signal receiving coils that can be adapted to and installed and fixed with existing long and short rod receiving coils, and can adjust the height of the receiving coils to simulate various receiving scenarios, reproduce the on-vehicle installation of locomotive signal receiving coils, and test the sensitivity of the equipment to receive ground signals, as an improvement and perfection of the locomotive signal equipment simulation test system, is a technical problem that urgently needs to be solved in this field.

[0053] Drive motor 16 is fixedly connected to the bottom of the support plate of the three-stage support leg 13. Drive motor 16 is a stepper motor.

[0054] Mounting bracket assembly 2, wherein the locomotive signal receiving coil 4 is symmetrically mounted on the support seats 141 at both ends of the support frame component 14;

[0055] Furthermore, such as Figure 6 As shown, the mounting bracket assembly 2 includes:

[0056] Support rod assembly 21, there are two sets of support rod assembly 21, each consisting of two cylindrical support rods, one of which has a threaded screw at one end and an anti-slip texture at the other end, and the other has a threaded pair at one end and an anti-slip texture at the other end. The support rod assembly 21 is detachably connected by passing through the connecting adjustment piece 22.

[0057] The connecting adjustment component 22 is used to adjust the starting height of the locomotive signal receiving coil 4. It can be selected according to the actual situation. There are two connecting adjustment components 22 in a set.

[0059] Specifically, such as Figure 6 As shown, the middle part of the connecting adjustment member 22 is a rectangular plate, one end of which is connected to a hollow cylindrical sleeve 221 through which the support rod assembly 21 passes, and the other end is connected to a connecting rod 222 with a threaded screw.

[0060] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, the lifting test device for railway locomotive signal receiving coil also includes a laser rangefinder 3, which is installed on a section of rail 5 on the rail support 15 for precise control of the lifting height.

[0061] In summary, the specific usage process of this invention is as follows:

[0062] In this embodiment, a set of mounting bracket assemblies 2 with connecting adjustment members 22 and a set of mounting bracket assemblies 2 without connecting adjustment members 22 are selected. Based on actual testing, the required length of the connecting adjustment member 22 is measured and prefabricated with the condition that the locomotive signal receiving coils 4 of both long and short poles can reach the same starting height.

[0063] First, test the long rod locomotive signal receiving coil 4.

After the lifting is adjusted to the predetermined height, a ground-based coding device simulates the on-site coding environment, sending a simulated signal to the locomotive signal receiving coil 4.

First, the connecting rod 222 of the connecting adjustment component 22 is passed through the mounting hole of the locomotive signal receiving coil 4 and locked and fixed with the locking component 23. Then, the support rod assembly 21 is passed through the sleeve 221 and tightened. Finally, the mounting bracket assembly 2 and the locomotive signal receiving coil 4 are installed on the support seat 141 of the lifting device body 1.

[0066] Furthermore, repeat the same test steps as for the locomotive signal receiving coil 4 on the long pole to complete the test of the locomotive signal receiving coil 4 on the short pole, record the key parameters and perform statistical analysis.

[0067] After all tests are completed, stop the lifting operation and turn off the power to all equipment.
