Description

Technical Field

[0001] The utility model relates to a novel transition coupler storage device for a motor vehicle, belonging to the technical field of rail transportation. Background Art

[0002] Currently, all rail transit equipment is equipped with transition couplers, which consist of a matching front and rear hook. These couplers are used in emergencies when a train malfunctions or is being sent back. The couplers are placed on a trolley, which is then pushed to transport them to the front of the train. Most existing transition couplers are stored in the front compartment of the head car at either end of the train or in the spare parts cabinet in the passenger compartment. Both methods have drawbacks: placing the coupler inside the head cover of the EMU requires a forklift or other tool for transport, which is inconvenient due to the short head section and limited space on some models. Placing the coupler in the passenger compartment spare parts cabinet takes up space and is not securely fixed. To address these issues, Chinese patent CN201420536850.9, titled "Transition Coupler Storage Device for EMUs," separates the coupler from the trolley for storage. The coupler is then secured to a bracket in the vehicle's spare parts cabinet, reducing space requirements. Chinese patent CN202222774494.1, titled "A Storage Device for Transition Couplers of EMUs," places the transition couplers in a storage box. The exterior of the storage box is equipped with a complex mechanism that can be used as a trolley. The slide rails must first be fixed to the floor of the EMU's storage compartment and then removed when in use. However, both of the above methods occupy space inside the EMU and require the provision or assembly of a separate trolley, which is very inconvenient. Furthermore, the transition couplers placed in the storage box are not positioned, resulting in poor stability. Utility Model Content

[0003] The purpose of the utility model is to provide a new type of transition coupler storage device for EMUs, which is installed at the lower part of the train body chassis and does not occupy the internal space of the EMU. The transition coupler is stored in a box together with a trolley. The box and the trolley loaded with the transition coupler are fixed longitudinally and transversely. A transition coupler transverse positioning seat and a transition coupler longitudinal positioning seat are provided on the trolley to fix the transition coupler, thereby solving the above-mentioned problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A new type of transition coupler storage device for a motor vehicle is installed on the train body chassis, comprising a box body, a lifting lug, a trolley, a stop block, a stop seat, a box door, a rubber buffer block, a transition coupler transverse positioning seat and a transition coupler longitudinal positioning seat. The top of the box body is provided with a lifting lug, which is installed on the car body chassis by chassis bolts. The front side of the box body is open and provided with a box door. The box door is a downward-folding movable box door. The inner surface of the box door is provided with a longitudinally arranged track guide strip. The bottom of the box body is provided with a track. The wheels of the trolley enter and exit the box body through the track guide strip and match the track. A transition coupler is provided on the bottom plate of the trolley A transverse positioning seat and a longitudinal positioning seat of the transition coupler, the transverse positioning seat of the transition coupler and the longitudinal positioning seat of the transition coupler respectively match the bottom structures of the front hook and the rear hook of the transition coupler to position the transition coupler on the trolley; a rubber buffer block is provided on the rear wall of the box body, and a limiting groove matching the rubber buffer block is provided at the front end of the bottom plate of the trolley. The rubber buffer block is embedded in the limiting groove at the front end of the bottom plate of the trolley to position the front end of the trolley; a stop seat is provided at the bottom of the front side of the box body, and a stop block matching the stop seat is provided at the rear end of the bottom plate of the trolley, and the stop seat and the stop block cooperate to position the rear end of the trolley.

[0006] An anti-collision plate is provided on the rear wall of the box body, and the rubber buffer block is fixed on the anti-collision plate.

[0007] The stop seat and the stop block are connected by a stop bolt and a butterfly nut, and the butterfly nut is easy to disassemble and assemble.

[0008] A telescopic arm is provided between the box door and the box body. When the box door flips down, the telescopic arm extends to limit the box door from flipping down to a horizontal state, thereby increasing the load-bearing capacity of the box door.

[0009] There are two lifting ears, which are welded to the left and right ends of the top of the box body and connected to the vehicle body chassis through chassis bolts. The width of the box body is consistent with the distance between the two lifting ears.
