Description

Technical Field

[0001] The present application relates to the field of EMU testing equipment, and in particular to a door mechanism testing equipment for EMUs. Background Art

[0002] In the field of EMU overhaul and maintenance, the performance test of the inner and outer door mechanisms is an important part of ensuring the safe operation of trains. However, for the test of the inner and outer door mechanisms of the CRH380 platform EMU, the traditional tooling design has significant limitations, that is, it is impossible to directly mount the door leaf for functional testing. This design defect leads to a key problem in the test process: during the test, the door mechanism can only mount a counterweight to simulate the weight of the door leaf, but cannot truly simulate the actual movement state, resistance and interaction with other components of the door leaf.

[0003] Due to this limitation, traditional test methods cannot fully evaluate the performance of door mechanisms in real working environments, such as key indicators such as the smoothness of door opening and closing and the effectiveness of anti-pinch functions. In addition, due to the differences in material, structure, and motion characteristics between the counterweight and the actual door leaf, the test results often have certain errors and are difficult to accurately reflect the actual performance of the door mechanism. Utility Model Content

[0004] The purpose of this application is to provide a door mechanism test device for EMUs, which can directly mount door leaves for testing, and is of great significance for improving the test accuracy and reliability of the inner and outer door mechanisms of CRH380 platform EMUs. This new test device can not only truly simulate the movement state of the door leaves, but also comprehensively evaluate the performance of the door mechanism in a real working environment, providing a more scientific and accurate basis for the inspection and maintenance of EMUs.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A door mechanism testing device for a multiple unit train comprises a box body, wherein two independent test areas are arranged in the box body, a mounting frame and an electrical control system are arranged in each of the independent test areas, the door mechanism is fixed to the mounting frame by a locking device, a door leaf is mounted below the door mechanism by a mounting device, a track is arranged at the bottom of the door leaf, the bottom of the door leaf is mounted on the track and can slide along the track to open and close the door, the electrical control system is used to control the movement of the door mechanism and simulate various operating conditions, and the electrical control system also comprises sensors and monitoring devices for real-time collection and analysis of data of the door mechanism during the test.

[0007] Furthermore, at least two locking devices are provided, and are respectively installed on the upper surface of the door mechanism through first bolts.

[0008] Furthermore, the locking device includes a locking seat and a second bolt, the middle portion of the locking seat protrudes upward to form a clearance portion, and the middle portion of the locking seat is locked on the mounting frame by the second bolt.

[0009] Furthermore, the mounting device includes a clamping plate and a locking bolt, and the clamping plate clamps the upper end of the door leaf and is locked by the locking bolt.

[0010] Furthermore, three layers of fireproof panels are provided on each side of the box.

[0011] Furthermore, anti-slip rubber strips are provided on the sides of the track.

[0012] Furthermore, buffer devices are respectively provided at both ends of the track.

[0013] Furthermore, an infrared sensor is also arranged in the box.

[0014] The beneficial effects of this application are:

[0015] Compared with traditional tooling, the door mechanism test equipment for EMUs described in this solution has significant advantages, mainly reflected in the following aspects:

[0016] (1) Due to height and structural design limitations, traditional tooling cannot simulate the movement of door leaves on the guide rails. This solution sets up a track system in the test area, allowing the door leaves to be installed on the track and slide along the track, truly simulating the opening and closing actions of the door leaves on the train, thereby greatly improving the accuracy and reliability of the test.

[0017] (2) Traditional tooling lacks simulation of the actual vehicle structure and cannot simulate the interaction between the door mechanism and other components. However, this solution simulates the installation frame and test area of ​​the actual vehicle structure, so that the door mechanism can fully simulate the coordinated movement with other components in the actual vehicle environment during the test, such as the interaction with other doors and body structures, so as to more accurately evaluate the performance of the door mechanism.

[0018] (3) The electrical control system in this solution is equipped with sensors and monitoring devices, which can collect and analyze the data of the door mechanism during the test in real time. This can not only help engineers understand the performance status of the door mechanism, but also provide a strong basis for subsequent optimization and improvement, further improving the efficiency and accuracy of the test.

[0019] (4) By setting up two independent test areas, this solution can perform two groups of tests simultaneously, thereby improving test efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, a door mechanism test equipment for a train set includes a box 1, two independent test areas 2 are arranged in the box 1, each independent test area 2 is provided with a mounting frame 3 and an electrical control system, a door mechanism a is fixed on the mounting frame 3 through a locking device 4, a door leaf b is mounted below the door mechanism through a mounting device 5, a track 6 is arranged at the bottom of the door leaf, the bottom of the door leaf is mounted on the track 6, and can slide along the track 6 to open and close the door, the electrical control system is used to control the movement of the door mechanism and simulate various operating conditions, and the electrical control system also includes sensors and monitoring devices for real-time collection and analysis of data of the door mechanism during the test. Compared with traditional tooling, the train set door mechanism test equipment proposed in this scheme simulates the real door opening and closing action by adding a track 6 system, simulates the existing vehicle structure to evaluate the interactive performance of the door mechanism and other components, is equipped with an electrical control system and sensors to realize real-time data collection and analysis, and sets up double test areas to improve the test efficiency, thereby significantly improving the accuracy and efficiency of the test.

[0031] The electrical control system adopts modular design, and each functional module is connected through a standard interface to facilitate maintenance and upgrade. The electrical control system includes infrared sensors, motor drivers, limit switches, counters, timers and other components, which are used to accurately control the opening and closing actions of the door leaves and detect faults. The control system has multiple working modes, such as automatic mode, manual mode, fault simulation mode, etc., to meet different test requirements.

[0032] In this embodiment, at least two locking devices 4 are provided, and are respectively installed on the upper surface of the door mechanism through first bolts.

[0033] like Figure 3 As shown, in this embodiment, the locking device 4 includes a locking seat 41 and a second bolt 42. The middle part of the locking seat 41 protrudes upward to form a space-avoiding portion, and the middle part of the locking seat 41 is locked on the mounting frame 3 by the second bolt 42. The design of the locking seat 41 makes the installation and removal of the door mechanism more convenient. When the door mechanism needs to be replaced or adjusted, the installation or removal of the door mechanism can be easily achieved by adjusting the tightness of the second bolt 42, thereby improving work efficiency.

[0034] like Figure 5 As shown, in this embodiment, the mounting device 5 includes a clamping plate 51 and a locking bolt 52. The clamping plate 51 is clamped to the upper end of the door leaf and then locked by the locking bolt 52. The design of the clamping plate 51 can firmly hold the upper end of the door leaf, ensuring that the door leaf will not shake or shift during the test, thereby ensuring the accuracy and reliability of the test. Since the clamping plate 51 can adapt to the upper ends of door leaves of different sizes and shapes, the mounting device 5 has strong versatility. This design enables the test equipment to be compatible with a variety of different models of door mechanisms, thereby improving the utilization rate of the equipment.

[0035] In this embodiment, three layers of fireproof panels are provided on each side of the box body 1. The main function of the fireproof panels is to provide fire protection. During the test of the EMU door mechanism, if an accidental fire occurs, the fireproof panels can effectively prevent the spread of the fire and reduce the threat of fire to the safety of equipment and personnel.

[0036] like Figure 1 As shown, in this embodiment, the side of the track 6 is provided with an anti-skid rubber strip 7. The softness and elasticity of the anti-skid rubber strip 7 can ensure that the door leaf maintains a certain gap with the side of the track 6 during the sliding process to avoid direct contact. In this way, not only the noise is reduced, but also the door leaf and the mounting frame 3 are protected, so that they can remain intact and effective for a longer time.

[0037] like Figure 1As shown, in this embodiment, buffer devices 8 are respectively provided at both ends of the track 6. The buffer device 8 can reduce the possibility of the door leaf directly colliding with the end of the track 6 or other fixed structures when closing, thereby preventing the door leaf from being damaged and extending its service life.

[0038] like Figure 1 As shown, in this embodiment, an infrared sensor 9 is also provided in the box 1. The infrared sensor 9 can detect the activities in the box 1 in real time, especially when a human body approaches or enters a potential hand-pinching area, the sensor can respond quickly.
