Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically to a bogie device for both road and rail shunting. Background Technology

[0002] In the intersection of rail and road transportation, traditional transportation equipment often faces challenges such as poor adaptability to different scenarios and low switching efficiency. Especially in situations where frequent switching between road and rail operating environments is required, such as railway freight yards and logistics hubs, traditional single-function transportation equipment is difficult to meet the demands for high efficiency and flexibility.

[0003] Traditional railway shunting locomotives are primarily designed for operations on railway tracks. While they possess strong traction and stability, they are cumbersome and inconvenient for road transport. Road transport vehicles, though flexible, cannot operate directly on railway tracks, requiring additional loading, unloading, and transshipment processes, which increases time and costs.

[0004] Furthermore, with the rapid development of the logistics industry, higher demands are being placed on the multi-scenario adaptability of transportation equipment. Especially against the backdrop of the Belt and Road Initiative and increasingly frequent global trade, there is a need for equipment that can adapt to both road and rail transportation environments to improve logistics efficiency and reduce transportation costs.

[0005] Therefore, there is an urgent market demand for a dual-purpose (rail-road) shunting locomotive that can meet the needs of railway shunting operations and flexibly switch to road transport modes. This equipment needs to possess high adaptability to different scenarios, rapid conversion capabilities, and stable operating performance to cope with complex and ever-changing transportation environments. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bogie device that can be used on both railway and highway tracks.

[0007] This utility model is achieved through the following technical solution:

[0008] A bogie assembly includes an on-rail steering component and an off-rail steering component. The on-rail steering component is connected to a first wheel set, and the off-rail steering component is connected to a second wheel set. The off-rail steering component is connected to a lifting drive structure. The first wheel set is connected to a first drive device, and the on-rail steering component includes a main load-bearing structure. The main load-bearing structure includes a support seat disposed at the middle position of the on-rail steering component, and the support seat is used to connect to the vehicle frame.

[0009] Furthermore, the on-orbit steering assembly includes a frame, with connecting frames at both ends of the frame, and buffer frames provided on the connecting frames. The first end of the buffer frame is hinged to the frame, and a shock-absorbing spring is provided between the second end of the buffer frame and the frame.

[0010] Furthermore, there are two sets of on-rail steering components, which are located at the front and rear ends of the vehicle frame.

[0011] Furthermore, the wheel set one includes multiple sets of track wheels, any set of track wheels being connected to each other via a drive shaft, and the drive device one includes a walking drive source connected to the drive shaft.

[0012] Furthermore, the on-rail steering assembly is also connected to a secondary support structure that cooperates with the side of the vehicle frame. The secondary support structure includes an upward elastic support body disposed on the side of the on-rail steering assembly.

[0013] Furthermore, the lifting drive structure includes a cantilever that cooperates with the vehicle frame, a lifting swing arm hinged to the lower end of the cantilever, and a drive swing arm that is hinged to the lifting swing arm.

[0014] Furthermore, the lifting arm is equipped with a hydraulic cylinder.

[0015] Furthermore, the walking wheels are in two sets, each set of which is connected to two lifting arms, which are located at the ends of the main shaft of the walking wheels.

[0016] Furthermore, the support base is connected to a traction shaft that cooperates with the vehicle body.

[0017] A dual-purpose shunting locomotive for both road and rail transport, comprising a bogie assembly.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1) Improved driving flexibility: By setting up on-rail and off-rail steering components, the dual-purpose road and rail shunting locomotive can move flexibly on the ground without relying on fixed tracks, which greatly enhances its adaptability and flexibility. This design enables the equipment to operate in a variety of terrains and environments, improving work efficiency and operating range.

[0020] 2) Enhanced track stability: When the bogie needs to travel along the rail, the on-rail steering component works and closely cooperates with the rail to provide stable guidance and support for the frame. This design effectively reduces the swaying and deviation of the vehicle when it travels on the track, and improves the stability and safety of the journey.

[0021] 3) Achieve rapid switching of working modes: The lifting design of the off-rail steering component allows the device to quickly switch between ground travel mode and rail travel mode. This rapid response capability enables the equipment to be flexibly adjusted according to actual work needs, improving work efficiency and operational efficiency.

[0022] 4) Reduced maintenance costs: Since the on-rail steering assembly and off-rail steering assembly perform different functions and are designed with their independence and durability in mind, the overall maintenance cost is reduced. Even if one part fails, it will not affect the normal operation of other parts, thus ensuring the overall reliability and service life of the equipment.

[0023] 5) Optimized space utilization: The lifting design of the off-rail steering component allows it to be retracted when the rail travel function is not in use, reducing the space occupied. This design optimizes the spatial layout of the equipment, making the equipment more convenient and efficient in storage and transportation.

[0024] In summary, the design of this bogie device has demonstrated significant benefits in improving driving flexibility, enhancing track stability, enabling rapid switching of operating modes, reducing maintenance costs, and optimizing space utilization. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0035] Example 1

[0036] like Figure 1-6 As shown, a bogie assembly includes an on-rail steering component and an off-rail steering component. The on-rail steering component is connected to a wheel set. Specifically, the on-rail steering component includes a frame 201, which is a rigid frame structure with high structural strength. A main load-bearing structure is connected to the frame 201. The main load-bearing structure includes a support seat 203 connected to the middle position of the on-rail steering component by a connecting beam. The support seat 203 is used to fix to the frame. The frame is the frame of a dual-purpose road-rail shunting locomotive 1. Two bottom beams 101 are fixed along the length direction at the middle position of the lower end of the frame. A traction axle 204 is installed on the support seat 203 and is connected to the frame.

[0037] There are two sets of on-rail steering components, which are distributed at the front and rear ends of the chassis, thus providing stable support for the chassis.

[0038] Wheel set one includes two sets of track wheels 207 for traveling on the track. The track wheels 207 are connected to each other by a drive shaft. Wheel set one is connected to drive device one. Drive device one includes a travel drive source connected to the drive shaft. Specifically, the drive shaft is a drive axle 202. The travel drive source is a geared motor connected to the drive axle 202, which can provide power to each set of track wheels 207 individually, thereby enabling on-track turning at a small angle. The working surface of track wheels 207 is fitted with a rubber layer to increase the friction between track wheels 207 and the track.

[0039] To better control the height, connecting frames 210 are fixed at both ends of the frame 201. A buffer frame 205 is hinged to the connecting frame 210. The first end of the buffer frame 205 is hinged to the frame 201, and a shock-absorbing spring 209 is installed between the second end of the buffer frame 205 and the frame 201. This forms a shock-absorbing buffer during walking and improves the stability of turning and walking.

[0040] The on-rail steering assembly is also connected to a secondary support structure that cooperates with the side of the frame. The secondary support structure includes an upward elastic support 206 installed on the side of the frame 201, which can provide buffer support to the frame on the side, especially during steering, and can buffer the lateral pressure generated by the tilt of the frame.

[0041] The off-rail steering assembly is connected to a second wheel set and a lifting drive structure. The lifting drive structure includes a cantilever 211 that cooperates with the frame. A lifting swing arm 213 is hinged to the lower end of the cantilever 211. The position of the lifting swing arm 213 can be controlled by the cantilever 211. It also includes a drive swing arm, which is a hydraulic cylinder 212. The second wheel set is a travel wheel, which is a car wheel used to travel on the road surface. The travel wheel is connected to the drive axle.

[0042] The dual-purpose road-rail shunting locomotive 1 is equipped with a bogie device. The frame of the dual-purpose road-rail shunting locomotive 1 is equipped with two sets of on-rail steering components and off-rail steering components. The on-rail steering components and off-rail steering components in the same set are connected by a frame 201, so that the support position does not change when switching between on-rail and off-rail states, thus ensuring the stability of the frame. Two sets of track wheels 207 are distributed on both sides of the running wheels 208. Most of the time, the dual-purpose road-rail shunting locomotive 1 travels on the track.

[0043] During travel, the bogie assembly drives the frame to move via the traction shaft 204.

[0044] The working method is as follows:

[0045] When in the track state, the hydraulic cylinder 212 is in the retracted state, the traveling wheel 208 is in the suspended state, and the frame is supported to the track by the rail wheel 207, so that the dual-purpose road and rail shunting machine 1 can move on the track. When turning, the drive axle 202 drives the rail wheel to turn, and the dual-purpose road and rail shunting machine 1 can achieve on-track turning.

[0046] In the off-rail state, the hydraulic cylinder 212 is extended, and the traveling wheels 208 support the ground, causing the car frame to be lifted. The car frame is supported to the road surface by the traveling wheels 208, and the traveling wheels 208 are turned by the steering bridge 202. The dual-purpose road and rail shunting locomotive 1 achieves off-rail turning.

[0047] 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.
