Description

Technical Field

[0001] This utility model relates to the field of pantograph detection technology, and in particular to a dynamic balance detection device for the pantograph head in subway systems. Background Technology

[0002] The pantograph is a key component of subway vehicles, responsible for obtaining electrical energy from the overhead contact line to drive the vehicle. Its performance directly affects the stable operation of the subway vehicle and the safety of passengers.

[0003] During subway train operation, the pantograph needs to maintain a good dynamic balance to ensure stable contact with the overhead contact line and reliable current transmission. However, due to the complexity and variability of subway lines, factors such as the height and curvature of the overhead contact line can affect the dynamic balance of the pantograph. Therefore, a specialized detection device is needed to monitor the dynamic balance of the pantograph in real time.

[0004] When using existing devices, traditional detection methods may rely on manual observation and measurement. This method is not only inefficient but also easily affected by human factors, resulting in low accuracy of the detection results. In addition, some existing detection devices may not be able to simulate the contact wire line when the subway is in motion, nor can they simulate the swaying sensation of the subway when it is in motion, and cannot accurately know the contact path between the pantograph head and the contact wire line. Therefore, we propose a dynamic balance detection device for the pantograph head of the subway to solve the above problems. Utility Model Content

[0005] The main purpose of this invention is to provide a dynamic balance detection device for the pantograph head in subways, which can effectively solve the problems of low efficiency and inability to simulate real conditions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A dynamic balance detection device for a subway pantograph head includes a support assembly, on the upper part of which a pantograph is fixedly connected, a drive assembly is fixedly connected to the inner cavity of the support assembly, and simulation assemblies are fixedly connected to the front and rear of the support assembly.

[0008] Preferably, the support assembly includes a support rod 1, with springs fixedly connected to the bottom walls of the inner cavities of the four support rods 1, and sliding rods fixedly connected to the upper ends of the four springs. Mounting plate 1 is fixedly connected to the upper ends of the four sliding rods, and two mounting plates 2 are fixedly connected to the front and rear side walls of the inner cavities of the support rods 1.

[0009] Preferably, the drive assembly includes a dual-axis motor, the lower end of which is fixedly connected to the upper end of the mounting plate 2, the output end of the dual-axis motor at the front is fixedly connected to a disc via a coupling, the front end of the disc is rotatably connected to a connecting rod, and the output end of the dual-axis motor at the rear is fixedly connected to a pulley 1 via a coupling.

[0010] Preferably, the simulation component includes support rods two, with one end of each of the four support rods two near the center being fixedly connected to one of the four support rods one, and pulleys three rotatably connected to the one end of each of the four support rods two near the center. Cables are wound around the outer surfaces of the pulleys three located on the same vertical line, and pulleys two are fixedly connected to the rear end of the pulleys three located at the rear end via a shaft. Belts one are wound around the outer surfaces of pulleys two and pulleys one.

[0011] Preferably, the lower end of the pantograph is fixedly connected to the upper end of the mounting plate by screws.

[0012] Preferably, the outer surfaces of the four sliding rods are slidably connected to the inner surfaces of the four support rods, and the upper end of the connecting rod is fixedly connected to the mounting plate located at the top.

[0013] Preferably, the front end of the second pulley is rotatably connected to the rear end of the second support rod located at the rear, and the rear ends of the two third pulleys located at the front are respectively fixedly connected to the third pulley located at the rear via shafts.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the setting of drive components and simulation components, can realize the rotation of the pantograph using cables, which can realistically simulate the dynamic contact state between the pantograph and the contact wire when the subway is in motion. This simulation helps to accurately evaluate the performance and stability of the pantograph in actual operation. Furthermore, through online dynamic detection, the status of the pantograph can be continuously monitored, and potential problems can be detected in time. Moreover, the automated and intelligent detection system can reduce manual intervention and reduce the risk of human error. This detection method is applicable to subway trains of different speeds and types, and has high versatility and adaptability.

[0016] 2. This utility model, through the design of support and drive components, simulates the swaying sensation of a subway train during operation, thus more realistically reproducing the working state of the pantograph in actual operation. This simulation helps to evaluate the performance of the pantograph in complex operating environments, including its stability, wear resistance, and adaptability. The simulated up-and-down movement process can more comprehensively detect the contact between the pantograph and the overhead contact line. This dynamic detection method can capture the minute changes of the pantograph under swaying conditions, thereby more accurately evaluating its performance. This not only improves the accuracy and reliability of detection but also helps to optimize the design of the pantograph, reduce maintenance costs, and enhance the overall safety of subway operation.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 As shown, a dynamic balance detection device for a subway pantograph head includes a support assembly 1, a pantograph 2 fixedly connected to the upper part of the support assembly 1, a drive assembly 3 fixedly connected to the inner cavity of the support assembly 1, and simulation assemblies 4 fixedly connected to the front and rear of the support assembly 1.

[0026] When implementing this solution, the operator first places the pantograph 2 on the support assembly 1 and fixes it with screws. Then, the operator first opens the pantograph 2. Then, the operator starts the output shaft at the rear of the drive assembly 3 to make the simulation assembly 4 rotate at high speed, thereby simulating the state of the subway moving at high speed. In this way, the specific state of the pantograph 2 contacting the simulation assembly 4 can be realized under the premise of ensuring safety.

[0027] When it is necessary to simulate the swaying sensation of a moving subway, the operator starts the output shaft at the front of the drive assembly 3. At this time, the drive assembly 3 will cause the support assembly 1 to move up and down in a cycle, thereby realizing the swaying sensation of a moving subway. In this way, the dynamic contact pressure of the pantograph 2 in contact with the simulation assembly 4 can be observed, and whether the pantograph 2 fluctuates within the specified range of the simulation assembly 4.

[0028] Specifically, in order to simulate the situation of pantograph 2 during subway movement, such as Figure 2 As shown in the figure, in this scheme, the output end of the dual-shaft motor 31 is fixedly connected to a pulley 34 via a coupling.

[0029] For further details, please refer to [link / reference]. Figure 3 and Figure 5 The simulation component 4 includes support rod 2 41. The ends of the four support rods 2 41 near the center are fixedly connected to the four support rods 1 11. The ends of the four support rods 2 41 near the center are rotatably connected to pulleys 3 44. The outer surfaces of the pulleys 3 44 located on the same vertical line are connected to cables 45. The rear end of the pulleys 3 44 located at the rear is fixedly connected to pulley 2 42 via a shaft. The outer surfaces of pulley 2 42 and pulley 1 34 are connected to belt 1 43.

[0030] For further details, please refer to [link / reference]. Figure 1 The lower end of the pantograph 2 is fixedly connected to the upper end of the mounting plate 14 by screws.

[0031] For further details, please refer to [link / reference]. Figure 5 The front end of the second pulley 42 is rotatably connected to the rear end of the second support rod 41 located at the rear, and the rear ends of the two third pulleys 44 located at the front are respectively fixedly connected to the third pulley 44 located at the rear via shafts.

[0032] When implementing this solution, the operator first places the pantograph 2 on the mounting plate 14 and fixes it with screws. Then, the operator first opens the pantograph 2. Then, the operator starts the output shaft of the dual-axis motor 31 to drive the pulley 34 to rotate, thereby causing the belt 43, pulley 42, pulley 44 and cable 45 to rotate at high speed, thus simulating the state of the subway moving at high speed. In this way, the specific state of pantograph 2 contacting cable 45 can be realized under the condition of ensuring safety.

[0033] If the two output shafts of a dual-axis motor are driven by two independent motor units, or if they are independently controlled through a complex electrical and control system, then they can be started independently.

[0034] Example 2, based on Example 1, can simulate the situation of pantograph 2 when the subway is swaying during movement.

[0035] Specifically, in order to observe the contact between the pantograph 2 and the cable 45 when the pantograph 2 sways, such as Figure 2 and Figure 4 As shown, in this scheme, the support assembly 1 includes support rod 11. Springs 12 are fixedly connected to the bottom wall of the inner cavity of each of the four support rods 11. Sliding rods 13 are fixedly connected to the upper ends of each of the four springs 12. Mounting plate 14 is fixedly connected to the upper ends of the four sliding rods 13. Two mounting plates 25 are fixedly connected to the front and rear side walls of the inner cavity of the support rod 11.

[0036] For further details, please refer to [link / reference]. Figure 4 The outer surfaces of the four sliding rods 13 are slidably connected to the inner surfaces of the four support rods 11, and the upper end of the connecting rod 33 is fixedly connected to the mounting plate 15 located at the top.

[0037] For further details, please refer to [link / reference]. Figure 6 The drive assembly 3 includes a dual-axis motor 31. The lower end of the dual-axis motor 31 is fixedly connected to the upper end of the mounting plate 15. The output end of the dual-axis motor 31 at the front is fixedly connected to a disc 32 via a coupling. A connecting rod 33 is rotatably connected to the front end of the disc 32.

[0038] When implementing this solution, to simulate the swaying sensation of a moving subway, the operator starts the output shaft at the front of the dual-axis motor 31 to drive the disc 32 to rotate. This causes the connecting rod 33 to move up and down repeatedly under the rotation of the disc 32, which in turn pulls the mounting plate 15 to move up and down. At this time, the sliding rod 13 will move, and the spring 12 will cyclically contract and stretch, thus realizing the swaying sensation of a moving subway. In this way, the dynamic contact pressure of the pantograph 2 on the cable 45 can be observed, and whether the pantograph 2 fluctuates within the specified range of the cable 45.

[0039] In summary, the implementation process of this utility model is as follows:

[0040] The operator first places the pantograph 2 on the mounting plate 14 and fixes it with screws. Then, the operator first opens the pantograph 2. Then, the operator starts the output shaft of the dual-axis motor 31 to drive the pulley 34 to rotate, which in turn causes the belt 43, pulley 42, pulley 44 and cable 45 to rotate at high speed, thus simulating the state of the subway moving at high speed. In this way, the specific state of pantograph 2 contacting cable 45 can be realized under the condition of ensuring safety.

[0041] When it is necessary to simulate the swaying sensation of a moving subway, the operator starts the output shaft at the front of the dual-axis motor 31 to drive the disc 32 to rotate, causing the connecting rod 33 to move back and forth up and down under the rotation of the disc 32. This causes the connecting rod 33 to pull the mounting plate 15 up and down, at which time the sliding rod 13 will move, and the spring 12 will cyclically contract and stretch, thus realizing the swaying sensation of a moving subway. In this way, the dynamic contact pressure of the pantograph 2 contacting the cable 45 can be observed, and whether the pantograph 2 fluctuates within the specified range of the cable 45.

[0042] It should be noted that the specific installation method, circuit connection method, and control method of the dual-axis motor 31 and other components used in this utility model are all conventional designs, and will not be described in detail in this utility model.
