Description

Technical Field

[0001] The utility model belongs to the technical field of train electric doors, and particularly relates to a flipping tooling for subway train electric doors. Background Technique

[0002] Train electric doors are an indispensable part of modern rail transit systems, and their reliability and stability are directly related to the safety and comfort of passengers. To ensure that the electric doors can operate normally under various working conditions, strict opening and closing tests are usually required. These tests simulate various scenarios of train electric doors during daily operation, including normal opening and closing, reverse when encountering resistance, emergency manual opening and closing, etc. Through these tests, the mechanical and electrical performance of the electric doors can be detected, their service life can be evaluated, and their stability and reliability under different environmental conditions can be ensured.

[0003] Currently, the opening and closing tests of electric doors are usually carried out in the horizontal position. These test benches are often composed of fixed support frames, and the electric doors are directly installed on the support frames. In the horizontal position, it is more convenient to install and disassemble the electric doors. However, the horizontal arrangement of the tests cannot fully simulate the real state of the electric doors during train operation, because during train operation, most electric doors are in the vertical state and are affected by gravity. In addition, although the tests in the horizontal position can detect some problems of the electric doors, they cannot comprehensively evaluate their performance during actual use.

[0004] There are certain limitations in the existing electric door opening and closing test devices without a flipping mechanism. First of all, due to the differences between the test environment and the actual application environment, the reliability of the test results is limited. The tests in the horizontal position cannot fully simulate the working conditions of the electric doors in the vertical state, so some problems that only occur during actual use may be ignored, such as the influence of the gravity effect of the electric doors in the vertical state on the door mechanism. In addition, the test devices of the existing technologies usually lack sufficient flexibility. Most electric doors are fixed on the tooling and cannot be flipped, resulting in that the electric door tests can only test locally and cannot easily flip the electric door to the vertical state for testing, which limits the diversity and comprehensiveness of the tests. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flipping tooling for subway train electric doors to solve at least one of the problems and defects mentioned in the above background technique.

[0006] Provide a flipping tooling for an electric door of a subway train, including a base, a support frame body is arranged on the base, a first bearing seat and a second bearing seat are respectively arranged on the support frame body, a first rotating shaft is rotatably connected to the first bearing seat, a second rotating shaft is rotatably connected to the second bearing seat, a door panel installation frame is arranged between the first rotating shaft and the second rotating shaft, a plurality of limiting mechanisms are arranged on the door panel installation frame, and the output end of a driving mechanism is fixedly connected to the side of the first rotating shaft away from the door panel installation frame;

[0007] During the use process, the driving mechanism drives the first rotating shaft to rotate so that the door panel installation frame is horizontally placed on the support frame body. The electric door is placed on the door panel installation frame by an external hoisting device, and the limiting mechanism is used to fix it for a horizontal test. In the state where the door panel installation frame is horizontally placed, a horizontal test of the electric door is carried out. The driving mechanism is started again, and the door panel installation frame is driven by the first rotating shaft to rotate to the vertical position, so that the electric door is in the vertical state for a vertical test. The driving mechanism is started again to restore the door panel installation frame to the horizontal position, which is convenient for removing the electric door and performing subsequent operations. It can more comprehensively detect the performance of the electric door in different positions and working conditions, thereby improving the diversity of the test and the reliability of the test results.

[0008] Furthermore, the driving mechanism includes a reducer, the reducer is fixedly connected to the support frame body, the output end of the reducer is fixedly connected to the first rotating shaft, and the input end of the reducer is fixedly connected to the output end of a flipping motor. When the flipping motor is started, it drives the output end of the reducer to rotate, and the reducer drives the first rotating shaft to rotate, thereby driving the door panel installation frame to flip, so as to flip the electric door limited and fixed on the door panel installation frame from the horizontal position to the vertical position, or from the vertical position back to the horizontal position to meet the test experiment requirements in different states.

[0009] Furthermore, the limiting mechanism includes a first limiting plate and a second limiting plate. The first limiting plate and the second limiting plate are symmetrically and slidably connected to the door panel installation frame. A first notch is arranged on the first limiting plate, and a second notch is arranged on the second limiting plate. After the first limiting plate and the second limiting plate slide to the appropriate positions on the door panel installation frame, the first limiting plate and the second limiting plate are fixed to the door panel installation frame through fastening bolts. The hinge parts of the electric door are clamped between the first limiting plate and the second limiting plate to keep the electric door in a stable position within the door panel installation frame and prevent it from flipping subsequently.

[0010] Further, a plurality of mounting holes are provided on the door panel mounting frame, and fastening bolts for passing through the mounting holes are provided in both the first notch and the second notch. By adjusting the sliding ranges of the first notch and the second notch, the mounting positions of the first limiting plate and the second limiting plate on the door panel mounting frame can be accurately controlled. Tighten the fastening bolts so that they pass through the first notch and the mounting hole to complete the fixation of the first limiting plate, and tighten the fastening bolts so that they pass through the second notch and the mounting hole to complete the fixation of the second limiting plate. The electric door hinge is clamped by the first limiting plate and the second limiting plate to ensure that the electric door will not be in danger due to loosening or displacement during the flipping and testing processes, ensuring the safety of the entire testing process.

[0011] Further, a plurality of limiting holes are provided on the second rotating shaft, a connecting seat is provided below the second rotating shaft, a positioning hole is provided on the connecting seat, and a brake pin for passing through the positioning hole and the limiting hole is detachably connected to the connecting seat. After the door panel mounting frame reaches a predetermined position (horizontal or vertical), that is, when the electric door reaches the horizontal or vertical test position, the brake pin locks the second rotating shaft through the positioning hole and the limiting hole to ensure that the door panel mounting frame remains stationary during the testing process, effectively preventing accidental rotation and deviation, and improving the safety of the testing process and the accuracy of the test results.

[0012] Further, a protective cover is also provided on the speed reducer. The protective cover provides mechanical protection and avoids damage to the speed reducer caused by external impacts, flying objects, mechanical impurities, etc.

[0013] Further, a first connecting plate is provided on the upper part of the support frame body, and a horizontal position travel switch is provided on the first connecting plate. The electric door on the door panel mounting frame approaches the horizontal position travel switch, triggers the horizontal position travel switch to transmit a signal to the controller. After receiving the signal, the controller immediately stops the rotation of the flipping motor to ensure that the door panel mounting frame stops at the horizontal position and ensures the accuracy of the horizontal test position.

[0014] Further, a second connecting plate is provided at the bottom of the support frame body, and a vertical position travel switch is provided on the second connecting plate. When the door panel mounting frame rotates to a position close to the vertical position, the electric door of the door panel mounting frame approaches the vertical position travel switch, triggers the vertical position travel switch to transmit a signal to the controller. After receiving the signal, the controller immediately stops the rotation of the flipping motor to ensure that the door panel mounting frame stops at the vertical position, ensures that the electric door is in the accurate vertical test position, and ensures the accuracy of the vertical test position.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] During the use process, the driving mechanism drives the first rotating shaft to rotate, so that the door panel installation frame is horizontally placed on the support frame. The electric door is placed on the support frame by an external hoisting device. A number of limiting mechanisms arranged on the door panel installation frame are used to clamp and fix the hinges of the electric door, so that the electric door can be fixed in the installation frame, ensuring that it will not shift or fall off during the flipping and testing process. The electric door is tested in the horizontal direction. After the test is completed, the driving mechanism is started again to drive the first rotating shaft to rotate, so that the installation frame is vertically placed on the support frame, and the electric door is in a vertical state for the opening and closing test. The electric door can be easily flipped to the vertical state for testing, ensuring the diversity and comprehensiveness of the test, so as to more realistically simulate the opening and closing process of the electric door in actual operation, thereby improving the accuracy and reliability of the test results.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0030] Please refer to Figures 1-5As shown in the figure, in the embodiment of the present utility model, a flipping tooling for an electric door of a subway train includes a base 1, which provides stable support for the entire tooling. A support frame 2 is fixed on the base 1 to provide a frame structure for the entire test system. The base 1 is provided with a support frame 2, and a first bearing seat 3 and a second bearing seat 4 are respectively arranged on the support frame 2. A first rotating shaft 5 is rotatably connected to the first bearing seat 3, and a second rotating shaft 6 is rotatably connected to the second bearing seat 4. A door panel installation frame 7 is arranged between the first rotating shaft 5 and the second rotating shaft 6. A number of limiting mechanisms 8 are arranged on the door panel installation frame 7. The door panel installation frame 7 is a structure for fixing the electric door to be detected. Through a number of limiting mechanisms 8 arranged thereon, the electric door can be fixed within the door panel installation frame 7 to ensure that it will not shift or fall off during the flipping and testing processes. One side of the first rotating shaft 5 away from the door panel installation frame 7 is fixedly connected to the output end of a driving mechanism 9, and the driving mechanism 9 is arranged on the support frame 2;

[0031] During the use process, the driving mechanism 9 drives the first rotating shaft 5 to rotate so that the door panel installation frame 7 is horizontally placed on the support frame 2. The electric door is placed on the support frame 2 through an external hoisting device. The hinge of the electric door is clamped and fixed by a number of limiting mechanisms 8 arranged on the door panel installation frame 7, so that the electric door can be fixed within the door panel installation frame 7. In the state where the door panel installation frame 7 is horizontally placed, horizontal tests of the electric door are carried out, including opening and closing operations and performance detections. The driving mechanism 9 is started again, and the door panel installation frame 7 is driven by the first rotating shaft 5 to rotate to the vertical position, so that the electric door is in the vertical state for vertical tests. In the vertical state of the electric door, opening and closing tests are carried out to more realistically simulate its working conditions during train operation, and various tests such as opening, closing, and encountering resistance are carried out. After the tests are completed, the driving mechanism 9 is started again to restore the door panel installation frame 7 to the horizontal position, which is convenient for removing the electric door and performing subsequent operations. Through this flipping tooling, the performance of the electric door in different positions and working conditions can be more comprehensively detected, thereby improving the diversity of the tests and the reliability of the test results, and ensuring the stability and safety of the electric door in actual applications.

[0032] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 4As shown, the driving mechanism 9 includes a speed reducer 91, which is fixedly connected to the support frame 2. The output end of the speed reducer 91 is fixedly connected to a first rotating shaft 5, and the input end of the speed reducer 91 is fixedly connected to the output end of a flipping motor 92. The flipping motor 92 can precisely control its operating state through a controller (not shown in the figure), such as starting and stopping, speed regulation, steering control, etc. When the flipping motor 92 starts, its output shaft rotates, converting electrical energy into mechanical energy. The output end of the flipping motor 92 is connected to the input end of the speed reducer 91, and the high-speed and low-torque motion is transmitted to the speed reducer 91. The speed reducer 91 reduces the high-speed rotation through an internal gear train and simultaneously amplifies the output torque. The output end of the speed reducer 91 is connected to the first rotating shaft 5, outputting a low-speed and high-torque rotational motion. The first rotating shaft 5 drives the door panel mounting frame 7 to flip, thereby flipping the electric door limited and fixed on the door panel mounting frame 7 from the horizontal position to the vertical position, or from the vertical position back to the horizontal position to meet the test experiment requirements in different states.

[0033] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the limiting mechanism 8 includes a first limiting plate 81 and a second limiting plate 82. The first limiting plate 81 and the second limiting plate 82 are symmetrically and slidably connected to the door panel mounting frame 7. A first notch 811 is provided on the first limiting plate 81, and a second notch 821 is provided on the second limiting plate 82. The first limiting plate 81 can slide a certain distance along the direction of the first notch 811 for installation, and the second limiting plate 82 can slide a certain distance along the direction of the second notch 821 for installation. In addition, both the first limiting plate 81 and the second limiting plate 82 are provided with clamping portions (not shown in the figure) for clamping the hinge parts of the electric door. After the first limiting plate 81 and the second limiting plate 82 slide to appropriate positions on the door panel mounting frame 7, the first limiting plate 81 and the second limiting plate 82 are fixed to the door panel mounting frame 7 through fastening bolts. The hinge parts of the electric door are clamped by the first limiting plate 81 and the second limiting plate 82, keeping the electric door in a stable position within the door panel mounting frame 7 and preventing it from shifting or falling off during subsequent flipping and testing.

[0034] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4Shown for the convenience of the fixed installation of the first limit plate 81 and the second limit plate 82 after they slide to the appropriate positions on the door panel installation frame 7, a number of installation holes 71 are provided on the door panel installation frame 7. Fastening bolts for passing through the installation holes 71 are provided in both the first notch 811 and the second notch 821. By adjusting the sliding ranges of the first notch 811 and the second notch 821, the installation positions of the first limit plate 81 and the second limit plate 82 on the door panel installation frame 7 can be precisely controlled, so that the entire limit mechanism 8 can adapt to electric doors of different sizes and specifications. During the adjustment process, until the first limit plate 81 and the second limit plate 82 limit and fix the hinge of the electric door, tighten the fastening bolt so that it passes through the first notch 811 and the installation hole 71 to complete the fixation of the first limit plate 81, and tighten the fastening bolt so that it passes through the second notch 821 and the installation hole 71 to complete the fixation of the second limit plate 82. By clamping the hinge parts of the electric door with the first limit plate 81 and the second limit plate 82, it is ensured that the electric door will not be dangerous due to loosening or displacement during the flipping and testing processes, firmly locking the entire electric door and ensuring the safety of the entire testing process.

[0035] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 5 As shown, a number of limit holes 61 are provided on the second rotating shaft 6 for locking the door panel installation frame 7 at different rotation angles. A connecting seat 10 is provided below the second rotating shaft 6, and a positioning hole 101 is provided on the connecting seat 10. The positioning hole 101 provides a fixed point for the insertion of the brake pin 11. When the second rotating shaft 6 rotates to a specific angle (such as the horizontal or vertical position), the limit hole 61 is aligned with the positioning hole 101, allowing the brake pin 11 to be inserted for locking. A brake pin 11 for passing through the positioning hole 101 and the limit hole 61 is detachably connected to the connecting seat 10. When the flipping motor stops running through a controller (not shown in the figure) and the door panel installation frame 7 reaches the predetermined position (horizontal or vertical), that is, when the electric door reaches the horizontal or vertical test position, the brake pin 11 locks the second rotating shaft 6 through the positioning hole 101 and the limit hole 61, ensuring that the door panel installation frame 7 remains stationary during the testing process, and further ensuring that the electric door will not be dangerous due to loosening or displacement during the flipping and testing processes, effectively preventing accidental rotation and deviation, and improving the safety of the testing process and the accuracy of the testing results.

[0036] In one embodiment, please refer to Figure 1 and Figure 2 As shown, a protective cover 93 is provided on the speed reducer 91. The protective cover 93 provides mechanical protection, avoiding damage to the speed reducer 91 caused by external impacts, flying objects, mechanical impurities, etc. The design of the protective cover 93 can reduce physical damage to the speed reducer 91 and extend its service life.

[0037] In one embodiment, please refer toFigure 1 , Figure 2 and Figure 5 As shown in Figure 1 , Figure 2 and Figure 5 , a first connecting plate 21 is provided on the upper part of the support frame body 2. A horizontal position travel switch 22 is provided on the first connecting plate 21. The horizontal position travel switch 22 is of the Keyence series, with precise photoelectric induction and suitable for occasions requiring high-precision mechanical manufacturing. Model examples are PZ-V31, PZ-V71, etc. When the door panel installation frame 7 rotates to a position close to the horizontal position, the electric door on the door panel installation frame 7 approaches the horizontal position travel switch 22, causing its contacts to close or open, triggering the horizontal position travel switch 22 to transmit a signal to the controller. After receiving the signal, the controller immediately stops the rotation of the flipping motor 92, ensuring that the door panel installation frame 7 stops at the horizontal position, ensuring that the electric door is in the accurate horizontal test position, and ensuring the accuracy of the horizontal test position. Through the trigger feedback of the horizontal position travel switch 22, the rotation angle of the flipping motor 92 and the final position of the door panel installation frame 7 are precisely controlled, avoiding the problems of over-rotation or under-rotation.

[0038] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 5 As shown in Figure 1 , Figure 2 and Figure 5 , a second connecting plate 23 is provided at the bottom of the support frame body 2. A vertical position travel switch 24 is provided on the second connecting plate 23. The vertical position travel switch 24 is also of the Keyence series, and model examples are also PZ-V31, PZ-V71, etc. When the door panel installation frame 7 rotates to a position close to the vertical position, the electric door on the door panel installation frame 7 approaches the vertical position travel switch 24, causing its contacts to close or open, triggering the vertical position travel switch 24 to transmit a signal to the controller. After receiving the signal, the controller immediately stops the rotation of the flipping motor 92, ensuring that the door panel installation frame 7 stops at the vertical position, ensuring that the electric door is in the accurate vertical test position, and ensuring the accuracy of the vertical test position.
