Description

Technical Field

[0001] This utility model relates to the field of subway vehicle maintenance equipment, specifically a multi-type coupler assembly trolley. Background Technology

[0002] Subway trains require maintenance and replacement of coupler buffers after operating for a certain distance or time. Currently, the disassembly and assembly of subway coupler buffers is underway:

[0003] Manual operation is the primary method: the disassembly and assembly of subway car couplers and buffers mainly rely on maintenance personnel using simple hand tools. This method is extremely inefficient, especially when disassembling and installing heavy couplers, which requires multiple people working together and is time-consuming.

[0004] High operational difficulty: Due to the limited space at the specific location of the coupler buffer at the end of the subway car, it is difficult to apply force manually. Furthermore, in some special car models, the installation angle of the coupler is more complex, which further increases the operational difficulty.

[0005] High safety risks: The coupler buffer itself is heavy, and during manual handling and disassembly, it can easily cause physical injury to maintenance personnel, posing a high safety hazard. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this utility model provides a multi-type coupler assembly trolley that is easy to adjust, adaptable to the disassembly and assembly of different types of couplers, convenient to use, and saves time and effort.

[0028] like Figure 1-3The diagram shows a multi-type coupler assembly trolley, including a car body 1 and casters 2 located at the bottom of the car body 1. The car body 1 is equipped with a hydraulic lifting mechanism 3 and a hydraulic station 4. A workbench 5 is installed on the top of the hydraulic lifting mechanism 3. Two transverse first slide rails 6 are arranged parallel to each other on the workbench 5. A front support 7 and a rear support 8 for supporting the coupler are slidably installed on the two first slide rails 6. The rear support 8 includes a base plate 801 slidably connected to the first slide rails 6. Two longitudinal second slide rails 802 are arranged parallel to each other on the base plate 801. Liftable support components are slidably installed on the two second slide rails 802.

[0029] The support assembly includes a support plate 803 slidably connected to the second slide rail 802. A hydraulic cylinder 804 for lifting is mounted on the support plate 803, and a support block 805 is mounted on the upper part of the telescopic end of the hydraulic cylinder 804. The rear support 8 controls the height of the support block 805 via the hydraulic cylinder 804 to adapt to different types of coupler suspension systems, thereby enhancing the stability of the coupler buffer.

[0030] The hydraulic lifting mechanism 3 includes a cross lifting rod 301 and a telescopic cylinder 302. The cross lifting rod 301 is connected to the vehicle body 1, and the telescopic end of the telescopic cylinder 302 is connected to the cross lifting rod 301. The hydraulic lifting mechanism 3 can adjust the height of the coupler installation position relative to the vehicle body, adapting it to the height position of the coupler buffer for different vehicle models, ensuring accurate operation. The coupler assembly trolley also includes a battery to power the hydraulic station 4.

[0031] The coupler assembly trolley also includes a positioning guide assembly 9 located at the front of the trolley body. The positioning guide assembly 9 includes a rotating shaft 901 rotatably connected to the trolley body 1. Connecting blocks 902 are respectively provided on both sides of the rotating shaft 901, and a fixed shaft 903 is installed between the two connecting blocks 902. Positioning guide wheels 904 are rotatably connected to both ends of the fixed shaft 903. The connecting blocks 902 are fan-shaped, and the distance between the two positioning guide wheels 904 matches the track width.

[0032] In one specific embodiment, a drive motor is provided on the side of the vehicle body 1, and the output end of the drive motor is fixedly connected to the rotating shaft 901.

[0033] The top of the front support 7 is provided with a V-shaped groove 701 for support. The front support 7 can be adjusted by moving the coupler support point back and forth via a slide rail, and the V-shaped groove design can increase the stability of the coupler placement.

[0034] The bottom of the front support 7, the bottom of the base plate 801, and the bottom of the support plate 803 are respectively provided with sliders 10 that are slidably connected to the corresponding slide rails, and a locking mechanism 11 is provided between the sliders 10 and the slide rails. Figure 4As shown, the slider 10 passes through the corresponding slide rail, and the locking mechanism 11 includes a screw 1101 rotatably connected to the slider 10. The tail of the screw 1102 is provided with a handle 1102. Rotating the handle 1102 causes the other end of the screw 1101 to abut against the corresponding slide rail, thereby achieving locking.

[0035] When using and installing this utility model, first move the coupler assembly trolley to the middle of the track. After locking the relative position of the coupler assembly trolley and the coupler mounting seat through the positioning guide component 9, raise the hydraulic lifting mechanism 3 to a certain height. Then, rotate the handle 1102 to separate the rotating rod 1103 from the slider 10. Manually release the locking mechanism 11 of the front support 7 and the rear support 8 on the slide rail. The front support 7 and the rear support 8 can slide on the first slide rail 6 to adjust their relative positions to accommodate different couplers. After adjusting the relative length, fix the front support 7 and the rear support 8. Place the coupler on the front support 7 using an overhead crane. Then, manually level the support block 805 by controlling the height of the support block 805 through the hydraulic cylinder 804. Then, push the coupler into the coupler mounting seat through the universal wheels. Because of the positioning guide component 9, the mounting hole of the coupler tail seat can be accurately and quickly aligned with the mounting hole of the mounting seat (if there is a slight horizontal deviation, the position of the support plate 803 can be slidably adjusted to easily align the holes). Tighten the bolts to complete the installation.

[0036] When disassembling this utility model, first move the coupler assembly trolley to the middle of the track. After locking the relative position of the coupler assembly trolley and the coupler mounting seat through the positioning guide component 9, determine the relative position of the front support 7 and the rear support 8 by sliding them on the slide rail. After the front support 7 is in close contact with the coupler, operate the rear support 8 to also be in close contact with the coupler. After the front support 7 and the rear support 8 are on the same horizontal plane, lock them. Loosen the 4 fastening bolts of the coupler seat, and move the assembly trolley horizontally away from the coupler mounting seat through the caster wheels to complete the coupler disassembly work.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
