Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit maintenance equipment technology, specifically to an auxiliary device for assembling train couplers. Background Technology
[0002] The coupler of a high-speed train is a vehicle component used to connect vehicles, locomotives, or power cars, transmitting traction and braking forces and mitigating longitudinal impact forces. The coupler is generally installed on a coupler buffer device, which is a whole unit consisting of the coupler, buffer, coupler tail frame, and trailing plate, installed in the traction beam at the end of the undercarriage frame.
[0003] Currently, in advanced repair workshops, the disassembly and assembly of couplers is limited by the deep installation position of the coupler at the end of the truck bed, requiring a considerable distance for the coupler to extend into the bed. Therefore, a forklift's fork is used to transport the coupler to the end of the truck bed via tooling for alignment and assembly. Before forklift assembly, a leveling machine is used to measure and adjust the coupler's levelness and end face perpendicularity. The forklift is then adjusted to the appropriate height, and manual assistance is used to align the bolt holes. The current coupler assembly method has certain problems:
[0004] (1) Qualified personnel are required to operate forklifts to assist in assembly;
[0005] (2) The coupler is difficult to align and requires manual and forklift coordination for alignment;
[0006] (3) The coupler posture is difficult to adjust, requiring the driver of the forklift to move and adjust it multiple times. Utility Model Content
[0007] The purpose of this invention is to provide an auxiliary device for assembling train couplers that is flexible, easy to operate, and suitable for coupler assembly in deeper positions.
[0008] To achieve the above objectives, this utility model is specifically implemented through the following technical solution:
[0009] A coupler assembly auxiliary device for high-speed trains includes a mobile chassis, a fixed frame, a lifting mechanism, a lateral moving mechanism, and a coupler support platform. The mobile chassis has wheels at its bottom. The fixed frame is vertically mounted at one end of the mobile chassis. The lifting mechanism is installed inside the fixed frame and includes two lifting rails, a lifting drive assembly, and a lifting bracket. The two lifting rails are vertically slidably connected to both sides of the fixed frame. The lifting drive assembly is installed in the middle of the fixed frame. The two sides of the lifting bracket are movably connected to the two lifting rails, and its middle part is drively connected to the lifting drive assembly. The lateral moving mechanism is movably installed inside the lifting bracket and includes a lateral drive assembly mounted on the lifting bracket and a platform fixing plate that laterally moves with the lifting bracket via the lateral rails. One end face of the coupler support platform is laterally fixed to the platform fixing plate.
[0010] Furthermore, a coupler front end frame is installed on the front side of the top surface of the coupler support platform, and a coupler rear end frame is installed on the rear side of the top surface.
[0011] Furthermore, a support rib is fixed at the bottom of the connection between the coupler support platform and the platform fixing plate.
[0012] Furthermore, the transverse slide rails are provided in two sets at the top and bottom of the lifting bracket.
[0013] Furthermore, the mobile chassis is equipped with a battery assembly and a driving assembly, with the driving wheels connected to the driving assembly via a transmission.
[0014] Furthermore, the fixed frame is equipped with an electronic control component. Both the lifting drive component and the lateral drive component are electrically driven, and the electronic control component is connected to the lifting drive component, the lateral drive component, the battery component, and the walking drive component for control.
[0015] Furthermore, a push rod is installed on the rear side of the mounting bracket.
[0016] This utility model provides a technical solution for the auxiliary disassembly and assembly of couplers on high-speed trains. It enables transportation, auxiliary support, and in-situ adjustment and alignment during the coupler disassembly and assembly process. The lifting platform for the fixed coupler can be pushed into the coupler installation position at the connecting end of the high-speed train via a mobile chassis. The height and horizontal position of the coupler support platform are precisely adjusted through the lifting mechanism and the lateral movement mechanism. This allows for the disassembly and assembly support operations of couplers on various train models, enabling disassembly and assembly operations without relying on external special equipment such as overhead cranes or forklifts. This facilitates operation, effectively reduces labor intensity, and improves disassembly and assembly efficiency. Attached Figure Description

[0027] like Figures 1 to 4 As shown, this utility model discloses an auxiliary device for assembling train couplers, including a mobile chassis 1, a fixed frame 2, a lifting mechanism 3, a lateral moving mechanism 4, and a coupler support platform 5. The mobile chassis 1 is equipped with traveling wheels 11 at its bottom. The device of this utility model adopts a non-standard chassis combined with a lifting platform. Due to space limitations at the installation location, the lifting platform needs to be designed to be relatively thin. The overall equipment dimensions are approximately 1700mm long × 720mm wide × 1600mm high. The mobile chassis 1 adopts an electric drive design with directional wheels, i.e., drive wheels with a diameter of 250mm and steering wheels with a diameter of 200mm, to adapt to rail crossing within the depot. The fixed frame 2 is vertically installed at one end of the mobile chassis 1. The lifting mechanism 3 is installed inside the fixed frame 2. It includes two lifting slide rails 31, a lifting drive assembly 32, and a lifting bracket 33. The two lifting slide rails 31 are vertically slidably connected to both sides of the fixed frame 2. The lifting drive assembly 32 is installed in the middle of the fixed frame 2. The two sides of the lifting bracket 33 are movably connected to the two lifting slide rails 31, and the middle part is connected to the lifting drive assembly 32. The lifting bracket 33 can be vertically lifted and lowered along the lifting slide rails 31 on both sides under the drive of the lifting drive assembly 32.
[0028] The lateral moving mechanism 4 is movably installed inside the lifting bracket 33, facing the top surface of the mobile chassis 1. The lateral moving mechanism 4 includes a lateral drive assembly 41 installed on the lifting bracket 33 and a platform fixing plate 43 that is laterally movable with the lifting bracket 33 via a lateral slide rail 42. The lateral moving mechanism 4 can move vertically with the lifting bracket 33. One end face of the coupler support platform 5 is laterally fixed on the platform fixing plate 43 and can move laterally along the lateral slide rail 42 with the platform fixing plate 43. The coupler support platform 5 is used to support the coupler and can be height adjusted.
[0029] During coupler installation, the mobile chassis 1 is pushed to the coupler connection point at the end of the EMU car. The lifting mechanism 3 and the lateral moving mechanism 4 are used to adjust the corresponding position of the coupler and the bolt holes at the connection point. After the adjustment is in place, the coupler is installed. During disassembly, the mobile chassis 1 is pushed to the end of the car. The lifting mechanism 3 and the lateral moving mechanism 4 are adjusted so that the coupler support platform 5 corresponds to the bottom surface of the coupler. After the coupler is disconnected from the car, the mobile chassis 1 will be driven out as a whole and pushed away from the bottom of the EMU car.
[0030] In some embodiments, a coupler front end frame 51 is installed on the front side of the top surface of the coupler support platform 5, and a coupler rear end frame 52 is installed on the rear side of the top surface of the coupler support platform 5. The coupler front end frame 51 and the coupler rear end frame 52 are used to support the coupler and position the coupler to prevent the coupler from slipping on the coupler support platform 5.
[0031] In some preferred embodiments, a support rib is fixed at the bottom of the connection between the coupler support platform 5 and the platform fixing plate 43. The coupler support platform 5 and the platform fixing plate 43 are perpendicular to each other, and the connection between the coupler support platform 5 and the platform fixing plate 43 is strengthened by the support rib.
[0032] In some embodiments, the transverse slide rails 42 are two sets installed at the top and bottom of the lifting bracket. The two sets of transverse slide rails 42 installed vertically can enhance the lateral load-bearing capacity of the platform fixing plate 43 and prevent deformation when the load-bearing coupler supports the platform 5 and the coupler.
[0033] In some embodiments, the mobile chassis 1 is equipped with a battery assembly and a walking drive assembly. The walking wheels 11 are connected to the walking drive assembly. The walking wheels 11 of the mobile chassis 1 are electric wheels, which are started and stopped by electric control, making operation convenient.
[0034] In some embodiments, the fixed frame 1 is provided with an electric control component 21, and the lifting drive component 32 and the lateral drive component 41 are both electrically driven. The electric control component 22 is connected to the lifting drive component 32, the lateral drive component 41, the battery component and the walking drive component respectively, and is used to electrically control the movement of the mobile chassis 1 and the coupler support platform. The electric lifting and positioning operation can be realized by clicking a button. The operation is convenient, flexible and controllable.
[0035] In some embodiments, a push rod 22 is provided on the rear side of the fixing frame to facilitate the operator's hand support and operation.
[0036] The specific embodiments described herein are merely illustrative of the invention and are not intended to limit it. Those skilled in the art can make modifications to these embodiments without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they fall within the scope of the claims of this invention.
