Abstract
Description
Technical Field
[0001] This application relates to the field of high-speed train component installation technology, specifically to a coupler installation device. Background Technology
[0002] As a connecting and buffering device for high-speed trains, the coupler plays a crucial role in coupling vehicles and transmitting traction and impact forces, making it an important basic component of the train. During high-speed train maintenance, the inspection and installation of the coupler is vital to ensuring its performance and safety. The old coupler must be removed, tested, and certified before reinstallation to ensure the normal operation of the high-speed train.
[0003] The current coupler installation process is as follows: First, the coupler is placed in a specific fixture, which is used to support and fix the coupler; then, a forklift is used to move the fixture with the coupler to the installation location; upon arrival, the forklift is operated to raise the coupler to a suitable height, and the forklift is precisely controlled to adjust the front-to-back and left-to-right positions of the coupler, so that the coupler is accurately aligned with the threaded hole of the vehicle body, thus completing the installation. The size of the coupler fixing bracket at the rear of the existing fixture is fixed.
[0004] As the number of EMU (Electric Multiple Unit) models increases, so too does the number of coupler models. However, existing tooling is only suitable for specific models because its coupler fixing bracket is not adjustable, which cannot meet the different installation requirements of couplers for various models. This severely limits the flexibility and adaptability of the work, and brings many inconveniences to actual maintenance work. Utility Model Content

[0032] As a connecting and buffering device for high-speed trains, the coupler plays a crucial role in coupling vehicles and transmitting traction and impact forces, making it an important basic component of the train. During high-speed train maintenance, the inspection and installation of the coupler is vital to ensuring its performance and safety. The old coupler must be removed, tested, and certified before reinstallation to ensure the normal operation of the high-speed train.
[0033] The current coupler installation process is as follows: First, the coupler is placed in a specific fixture, which is used to support and fix the coupler; then, a forklift is used to move the fixture with the coupler to the installation location; upon arrival, the forklift is operated to raise the coupler to a suitable height, and the forklift is precisely controlled to adjust the front-to-back and left-to-right positions of the coupler, so that the coupler is accurately aligned with the threaded hole of the vehicle body, thus completing the installation. The size of the coupler fixing bracket at the rear of the existing fixture is fixed.
[0034] As the number of EMU (Electric Multiple Unit) models increases, so too does the number of coupler models. However, existing tooling is only suitable for specific models because its coupler fixing bracket is not adjustable, which cannot meet the different installation requirements of couplers for various models. This severely limits the flexibility and adaptability of the work, and brings many inconveniences to actual maintenance work.
[0035] Figure 1 This is a schematic diagram of the structure of a coupler mounting device provided in an embodiment of this application; Figure 2 This is a schematic diagram of the upper part of a coupler mounting device provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of the motor portion between the slide rails provided in an embodiment of this application; Figure 4 This is a schematic diagram of the installation component provided in the embodiments of this application; Figure 5 This is a schematic diagram of the transmission components of the lifting mechanism provided in the embodiments of this application.
[0036] To address the problems mentioned in the background art and to achieve the goal of actively adjusting and adapting to the coupler size, this application provides a coupler installation device. For example... Figure 1-5 As shown, the installation includes a mounting assembly 100, which includes a first slider 110, a first platform 120, and multiple first rods 130. The first slider 110 and the first platform 120 are connected by the first rods 130, and the first platform 120 can be raised and lowered relative to the first slider 110.
[0037] The second platform 140 is slidably connected to the first platform 120. A first bracket 200 is installed on the side of the second platform 140 opposite to the first platform 120. The first bracket 200 has multiple sets of rotating parts 210 in the middle. The multiple sets of rotating parts 210 are arranged to form an annular ring for accommodating the coupler. The rotating parts 210 can rotate relative to the first bracket 200 to adjust the maximum size of the coupler that can be accommodated.
[0038] It should be noted that the first platform 120 can be raised and lowered relative to the first slider 110, and the second platform 140 is slidably connected to the first platform 120. This design allows the coupler mounting device to be flexibly adjusted in position during operation. Compared to traditional tooling that relies entirely on forklifts for operation, this device can independently achieve the raising, lowering, and horizontal movement of the coupler, reducing dependence on external equipment, lowering the difficulty of operation, and avoiding the collision risks that may occur when forklifts operate in confined spaces. This ensures the safety of operators and the integrity of the vehicle body, and improves the overall convenience of operation.
[0039] The lifting of the first platform 120 and the sliding of the second platform 140 enable precise adjustment of the coupler position. Combined with manual screw control, operators can more accurately align the threaded holes on the coupler with the corresponding threaded holes on the car body, reducing the number of adjustments and thus improving the coupler installation accuracy. Furthermore, the operation is more convenient and efficient, effectively reducing installation time and improving work efficiency.
[0040] Multiple rotating parts 210 in the middle of the first bracket 200 form an annular ring to accommodate the coupler. The rotating parts 210 can rotate relative to the first bracket 200 to adjust the maximum size of the coupler that can be accommodated. This design echoes the technical point of the variable diameter fixed bracket. This device can adapt to couplers of various diameters, meeting the installation requirements of couplers for different vehicle models, improving the equipment's versatility, effectively solving the problem that traditional tooling is only suitable for a single vehicle model, and enhancing the equipment's flexibility and adaptability when dealing with diverse coupler models.
[0041] Furthermore, it's worth mentioning that when there are no production tasks, the equipment is at its lowest point with the hydraulic rod retracted. During coupler installation, the bolts on the first bracket 200 are removed from the bolt holes. The coupler is placed on both the rear and front first brackets 200, and the bolts are then reconnected and securely tightened through the bolt holes. The rotating part 210 then completely encloses the coupler. After the coupler is placed and secured on the equipment, it is moved to the installation location, completing all preparations for installation.
[0042] According to one embodiment of this application, a first lead screw 150 is also installed between the first slider 110 and the first platform 120, and the first lead screw 150 drives the first platform 120 to rise and fall relative to the first slider 110.
[0043] According to one embodiment of this application, a second lead screw 160 is installed between the second platform 140 and the first platform 120, and the second lead screw 160 drives the second platform 140 to slide relative to the first platform 120.
[0044] It should be noted that the first lead screw 150 drives the first platform 120 to rise and fall relative to the first slider 110, and the second lead screw 160 drives the second platform 140 to slide relative to the first platform 120, enabling the coupler installation device to be adjustable in both vertical and horizontal directions. Lead screw drives are characterized by high transmission precision and smooth movement, allowing operators to achieve extremely fine adjustments to the coupler position by controlling the rotation of the lead screw. During coupler installation, the threaded holes on the coupler must be precisely aligned with the corresponding threaded holes on the car body. This precise control ensures the accuracy of the installation position, reduces problems such as unstable coupler connections caused by installation deviations, thereby improving the installation quality of the coupler and ensuring the safety and stability of the EMU operation.
[0045] Compared to other transmission methods, the lead screw drive system offers superior self-locking performance. Once the first platform 120 and the second platform 140 are properly positioned, the lead screw remains stable, preventing accidental movement of the platforms due to external forces or their own weight. During coupler installation, the coupler itself has a certain weight and requires a stable posture. The self-locking characteristics of the first lead screw 150 and the second lead screw 160 provide reliable support for the coupler, preventing swaying or displacement during installation. This makes the entire installation operation more stable and reliable, reduces operational risks, and also helps improve work efficiency.
[0046] Furthermore, it should be noted that if the rear of the coupler needs adjustment, rotating the screw handle of the first support 200 at the rear end can control its raising or lowering. Clockwise rotation raises the rear of the coupler, and counterclockwise rotation lowers it. Rotating the other screw handle moves the rear of the coupler left or right; clockwise rotation moves the rear to the left, and counterclockwise rotation to the right. Precise adjustments can be made according to the actual production situation. The adjustment of the front of the coupler follows the same principle; to adjust the front, control the first support 200 at the front end. Both the front and rear supports can move back and forth on the third platform 300 using the first slider 110 on the slide groove, achieving more comprehensive adjustments and making the entire installation work quick and precise. After adjustment, tighten the coupler mounting bolts, remove the bolts on the first support 200 at the rear end from the bolt holes, and operate the button on the handle again. The motor 420 moves the third platform 300 out of the coupler box, the hydraulic rod of the lifting mechanism 520 extends and retracts, the equipment lowers, and the equipment is moved to the storage location, completing the installation work.
[0047] According to one embodiment of this application, it further includes a third platform 300, which has a groove, and the first slider 110 is installed in the groove.
[0048] According to one embodiment of the present application, the system further includes a fourth platform 400, which has a plurality of slide rails 410 extending toward the third platform 300. The third platform 300 is provided with a plurality of second sliders 310 on the side near the fourth platform 400, and the second sliders 310 are installed in cooperation with the slide rails 410.
[0049] It should be noted that the cooperation between the sliding groove of the third platform 300 and the first slider 110, and the cooperation between the slide rail 410 of the fourth platform 400 and the second slider 310, further refines the position adjustment during coupler installation. The sliding cooperation between multiple platforms makes position adjustment during coupler installation more convenient and efficient. Compared to traditional installation methods, operators do not need to spend a lot of time and effort on complex position adjustments and corrections. The sliding of the slider within the sliding groove and slide rail 410 can distribute these forces across the entire platform structure, preventing excessive local stress that could damage the equipment.
[0050] According to one embodiment of this application, the fourth platform 400 further includes a motor 420, which is disposed between slide rails 410. The output end of the motor 420 is connected to a coupling 430 via a rotating rod. The output end of the coupling 430 is connected to a third lead screw 440, and the output end of the third lead screw 440 is connected to the fourth platform 400 to drive the fourth platform 400 to move relative to the third platform 300.
[0051] It should be noted that the combination of motor 420, coupling 430, and third lead screw 440 provides an automated drive for the movement of the fourth platform 400 relative to the third platform 300. By precisely controlling the rotational speed and angle of the motor, the movement distance and position of the fourth platform 400 can be accurately adjusted. During coupler installation, the accuracy requirements for the installation position of couplers for different car models are extremely high. Automated control can avoid errors that may be caused by manual operation, ensuring that the coupler installation position meets strict technical standards and improving the quality and consistency of coupler installation.
[0052] Coupling 430 effectively buffers torque fluctuations from the motor output, reduces vibration and impact during transmission, and ensures that the third lead screw 440 smoothly drives the fourth platform 400. Simultaneously, the lead screw drive itself has a self-locking characteristic, ensuring that once the fourth platform 400 reaches the designated position, it reliably remains there without displacement due to external interference, thus improving the stability and reliability of the equipment during coupler installation.
[0053] According to one embodiment of this application, the first bracket 200 further includes at least two arc-shaped plates 220, which are connected by bolts. The inner side of the arc-shaped plate 220 is provided with an arc-shaped groove for mounting the rotating part 210.
[0054] According to one embodiment of this application, each rotating part 210 includes at least three arc-shaped blocks, one of which is rotatably connected to the arc plate 220, and the other two arc-shaped blocks connected to the arc plate 220 are rotatably connected to each other.
[0055] It should be noted that the rotating part 210 includes a large semi-circular arc block and two smaller semi-circular arc blocks. All semi-circular arc blocks are rotatable. When dealing with different types of couplers, by increasing or decreasing the number of arc plates 220, the problem of traditional tooling being unable to adapt to multiple couplers is effectively solved. The arc-shaped groove opened on the inner side of the arc plate 220 precisely fits the installation of the rotating part 210, ensuring that the rotating part 210 remains stable during rotation, providing reliable support for the coupler, and greatly improving the adaptability of the coupler installation device to changes in coupler size.
[0056] According to one embodiment of this application, the system further includes a second bracket 500 and a first housing 510. Both the second bracket 500 and the first housing 510 are installed on one side of the fourth platform, and the other end of the second bracket 500 is connected to the first housing 510.
[0057] According to one embodiment of this application, a lifting mechanism 520 is installed at the bottom of the first box 510 to raise the height of the first box 510.
[0058] It should be noted that the lifting mechanism 520 is primarily controlled by a hydraulic system. The power supply controls the extension and retraction of the hydraulic rod in the hydraulic system via buttons on the operating handle, thus raising or lowering the equipment. The lifting mechanism 520 is completely concealed within the equipment. When there is no production task requiring the coupler, the hydraulic rod retracts, and the lifting mechanism 520 reaches its lowest point, aligning perfectly with the equipment casing, saving space. A support device is also installed at the bottom of the equipment. During operation, pulling the handle of the support device extends it, and rotating the handle secures it, ensuring the stability of the entire equipment and guaranteeing smooth operation.
