Description

Technical Field

[0001] This invention belongs to the field of railway tracks, and specifically relates to a track bridging device and a rail transport vehicle system. Background Technology

[0002] Steel rails are an important component of railway tracks, mainly used to guide the wheels of locomotives and rolling stock. After prolonged use, steel rails will suffer some damage. It would be wasteful to simply discard them, so they need to be recycled and reused to save on raw materials. During the recycling and transportation of steel rails, loading, unloading and transporting steel rails are carried out on long rail cars. When loading, unloading and transporting steel rails between adjacent train sets, a track bridging device is needed to control the connection and disconnection of adjacent train sets.

[0003] The existing track bridging device is a device that connects the tracks used to guide the trolley on adjacent train sets into a whole when loading, unloading and transporting rails between adjacent train sets. The guide trolley is used to load, unload and adjust the rails. Specifically, the existing track bridging device is installed on the side beams or side columns of the underframe of the adjacent train sets. It connects the tracks used to guide the trolley on the adjacent train sets through fixed and sliding parts. During the loading and unloading of rails, after the rails are loaded and unloaded in one train set, a crane is used to connect the track bridging device and move the guide trolley to another train set. During the transportation of rails, the crane is used to disconnect the track bridging device to realize the transportation of the rails.

[0072] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0073] The existing track bridging device is a device that connects the tracks used to guide the trolley on adjacent train sets into a whole when loading, unloading and transporting rails between adjacent train sets. The guide trolley is used to load, unload and adjust the rails. Specifically, the existing track bridging device is installed on the side beams or side columns of the underframe of the adjacent train sets. It connects the tracks used to guide the trolley on the adjacent train sets through fixed and sliding parts. During the loading and unloading of rails, after the rails are loaded and unloaded in one train set, a crane is used to connect the track bridging device and move the guide trolley to another train set. During the transportation of rails, the crane is used to disconnect the track bridging device to realize the transportation of the rails.

[0074] However, existing track bridging devices require cranes for connection and disconnection, making operation inconvenient.

[0075] To address the aforementioned problems, this application provides a rail bridging device and a rail transport vehicle system. The rail bridging device utilizes its own bridging components, drive components, and lifting components. The first drive component drives the movable bridging unit of the bridging component, while the second drive component drives the support frame of the lifting component, which in turn moves the fixed bridging unit of the bridging component. Under the combined drive of the first and second drive components, the movable and fixed bridging units are connected and disconnected, enabling the rail bridging device to connect and disconnect without the need for a crane. This simplifies operation, as it can be operated manually by turning a wrench, reducing safety hazards for operators.

[0076] The specific content of the present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0077] During the loading and unloading of rails, after the rails are loaded and unloaded in one train set, a crane is used to connect the rail bridging device and move the guide trolley to another train set. During the transport of the rails, the crane is used to disconnect the rail bridging device to realize the transport of the rails. In this solution, the rail bridging device and rail transport vehicle system do not require the cooperation of a crane during the connection and disconnection of the rail bridging device. Under the joint drive of the first drive component and the second drive component, the moving bridging unit and the fixed bridging unit are driven to realize the connection and disconnection of the rail bridging device, which is convenient to operate. Figure 1 This is a schematic diagram of the connection structure of a rail bridging device on a rail transport vehicle system, provided as an embodiment of the present invention. Figure 1 As shown, the rail bridging device and rail transport vehicle system are applied to the rail transport vehicle 210. The guide trolley 300 is used to load, unload, and adjust the rails 400. The guide trolley 300 moves on the rails set on the long rail vehicle and on the bridging rails 500 between adjacent vehicle groups. During the loading and unloading of the rails 400, the rail bridging device 100 is connected to allow the guide trolley 300 to move between adjacent vehicle groups. During the transport of the rails 400, the rail bridging device 100 is disconnected to achieve normal transport of the rails 400. The rail bridging device 100 includes a bridging component 110 and a drive component 120. Figure 2 for Figure 1 The main view of the connection status of the bridging component. For example... Figure 2 As shown, the bridging assembly 110 includes a fixed bridging unit 112 and a movable bridging unit 111. The fixed bridging unit 112 includes a fixed bridging arm 1121, which is disposed on the first of the two rail transport vehicles 210. The movable bridging unit 111 includes a movable bridging arm 1111, which is movably disposed on the second of the two rail transport vehicles 210. The drive assembly 120 includes a first drive unit 121, which is connected to the movable bridging arm 1111 and configured to drive the movable bridging arm 1111 to move toward the fixed bridging arm 1121, so that the movable bridging arm 1111 and the fixed bridging arm 1121 are interconnected and form a bridging track 500 connecting the rails 400 of the two rail transport vehicles 210.

[0078] Figure 3 for Figure 1 The main view of the bridge component in the disconnected state. (Example) Figure 3As shown, the fixed bridging arm 1121 has a first track portion 1124 and a slide groove 1125 arranged side by side in the vertical direction at one end facing the movable bridging arm 1111. The movable bridging arm 1111 has a second track portion 1116 and an insertion portion 1117 arranged side by side in the vertical direction at one end facing the fixed bridging arm 1121. When the insertion portion 1117 is inserted into the slide groove 1125, the first track portion 1124 and the second track portion 1116 are connected to each other, and the top surfaces of the first track portion 1124 and the second track portion 1116 are flush with each other, so that the movable bridging arm 1111 and the fixed bridging arm 1121 are connected to each other and form a bridging track 500. Specifically, in the track bridge... When the connecting device 100 is connected, the first track section 1124 and the track on the long rail car group are connected to each other, the first track section 1124 and the second track section 1116 are connected to each other, the second track section 1116 and the track on the long rail car group are connected to each other, and the top surfaces of the first track section 1124, the second track section 1116 and the track on the adjacent long rail car group are flush with each other. The insertion part 1117 of the movable bridge arm 1111 and the slide groove 1125 of the fixed bridge arm 1121 are connected to each other, realizing the mutual connection of the movable bridge arm 1111 and the fixed bridge arm 1121. The bridge track 500 formed and the track on the long rail car group enable the guide trolley 300 to move between adjacent car groups.

[0079] Optionally, the movable bridging unit 111 further includes a base 1112 and a first connecting arm 1113. The base 1112 supports the movable bridging arm 1111 and the first connecting arm 1113. A slide rail 1118 is provided on the base 1112, and the first connecting arm 1113 is slidably disposed on the slide rail 1118, allowing the first connecting arm 1113 to slide horizontally on the slide rail 1118. The first end of the movable bridging arm 1111 and the end of the first connecting arm 1113 are hinged. When the first connecting arm 1113 slides horizontally on the slide rail 1118, it drives the movable bridging arm 1111 to move horizontally. The second end of the movable bridging arm 1111 is used to insert into the fixed bridging arm 1121, realizing the mutual connection between the movable bridging arm 1111 and the fixed bridging arm 1121.

[0080] Optionally, the movable bridging unit 111 further includes a first rotating shaft connector 1114. The first end of the movable bridging arm 1111 and the end of the first connecting arm 1113 are respectively hinged to the first rotating shaft connector 1114. Specifically, when the first connecting arm 1113 slides horizontally on the slide rail 1118, it drives the first rotating shaft connector 1114 to move horizontally, thereby driving the movable bridging arm 1111 to move horizontally. The rotation axis of the movable bridging arm 1111 relative to the first rotating shaft connector 1114 and the rotation axis of the first connecting arm 1113 relative to the first rotating shaft connector 1114 have an included angle. On the one hand, during the loading and unloading of the rail 400, the movable bridging arm 1111 can be better adjusted and more easily connected to the fixed bridging arm 1121. On the other hand, during the transport of the rail 400, when the long rail car passes through the curved rail, the movable bridging arm 1111 releases its lateral and vertical degrees of freedom, making it easier to pass through the curved rail.

[0081] Figure 4 for Figure 1 Left view of the first drive unit in the diagram. (See image below.) Figure 4 As shown, the first drive unit 121 includes a first drive rod 1211, a second drive rod 1212, and a first coupling 1213. The first drive rod 1211 is horizontally mounted at the bottom of the rail transport vehicle 210, and the first end of the first drive rod 1211 is formed as the force-applying end. The second drive rod 1212 is vertically mounted, and the first end of the second drive rod 1212 is connected to the second end of the first drive rod 1211 through the first coupling 1213. Figure 5 for Figure 1 The main view of the first drive unit in the diagram. (See image below.) Figure 5As shown, the first drive unit 121 further includes a second coupling 1214 and a lead screw 1215. The second coupling 1214 and the lead screw 1215 are horizontally arranged, and the lead screw 1215 is connected to the second end of the second drive rod 1212 through the second coupling 1214. The lead screw 1215 is used to drive the movable bridging arm 1111 to move. During the process of connecting and disconnecting the track bridging device 100, the force-applying end is driven by manually turning a wrench, thereby driving the first drive rod 1211 to rotate. For example, in an optional embodiment, the force-applying end includes a first bearing seat 1216 and a first bearing 1217. A first steering box 1218 is provided between the second end of the first drive rod 1211 and the first coupling 1213, and a second steering box 1219 is provided between the second end of the second drive rod 1212 and the second coupling 1214. The lead screw 1215 and the first connecting arm 1113 of the bridging assembly 110 are provided with... With a connecting plate 1115, specifically, during the connection and disconnection of the track bridging device 100, the first bearing 1217 on the first bearing seat 1216 is rotated manually by turning a wrench, driving the first drive rod 1211 to rotate. Under the drive of the first steering box 1218, the horizontal rotation of the first drive rod 1211 is converted into the vertical rotation of the second drive rod 1212 through the connection of the first coupling 1213. Then, under the drive of the second steering box 1219, the vertical rotation of the second drive rod 1212 is converted into the horizontal rotation of the lead screw 1215 through the connection of the second coupling 1214. Driven by the connecting plate 1115, the first connecting arm 1113 is driven to slide horizontally on the slide rail 1118, realizing the horizontal movement of the moving bridging arm 1111. The track bridging device 100 does not require the assistance of a crane during the connection and disconnection process, making it easy to operate.

[0082] Optionally, the fixed bridging unit 112 further includes a second rotating shaft connector 1123 and a second connecting arm 1122. The first end of the fixed bridging arm 1121 and the end of the second connecting arm 1122 are respectively hinged to the second rotating shaft connector 1123. The rotation axis of the fixed bridging arm 1121 relative to the second rotating shaft connector 1123 and the rotation axis of the second connecting arm 1122 relative to the second rotating shaft connector 1123 have an included angle. On the one hand, during the loading and unloading of the rail 400, the fixed bridging arm 1121 can be better adjusted and more easily connected to the movable bridging arm 1111. On the other hand, during the transport of the rail 400, when the long rail car passes through the curved rail, the movable bridging arm 1111 is freed from lateral freedom and passes through the curved rail more easily.

[0083] Optionally, the track bridging device 100 further includes a lifting assembly 130, which is mounted on the rail transport vehicle 210 and supported below the fixed bridging arm 1121. While the first drive unit 121 drives the movable bridging arm 1111 to move horizontally, the lifting assembly 130 drives the fixed bridging arm 1121 to move vertically, thereby realizing the connection or disconnection between the movable bridging arm 1111 and the fixed bridging arm 1121.

[0084] Figure 6 for Figure 1 The main view of the raised component. (Example) Figure 6 As shown, the lifting assembly 130 includes a lifting base 131 and a support frame 132 movably mounted on the lifting base 131. The lifting base 131 is used to connect with the rail transport vehicle 210. The support frame 132 is configured to move vertically relative to the lifting base 131 to support the fixed bridging arm 1121 at different heights. While the first drive unit 121 drives the movable bridging arm 1111 to move horizontally, the support frame 132 of the lifting assembly 130 drives the fixed bridging arm 1121 to move vertically, thereby realizing the connection or disconnection of the movable bridging arm 1111 and the fixed bridging arm 1121.

[0085] Optionally, the drive assembly 120 may also include a second drive unit 122. Figure 7 for Figure 1 Left view of the second drive unit. (See image below.) Figure 7As shown, the second drive unit 122 includes a third drive rod 1221, a fourth drive rod 1222, and a third coupling 1223. The third drive rod 1221 is horizontally positioned at the bottom of the rail transport vehicle 210, and its first end forms a force-applying end. The fourth drive rod 1222 is vertically positioned, and its first end is connected to the second end of the third drive rod 1221 via the third coupling 1223. The second end of the fourth drive rod 1222 is used to drive the support frame 132 to move vertically. During the connection and disconnection of the rail bridging device 100, the force-applying end is driven by manually rotating a wrench, thereby driving the third drive rod 1221 to rotate. For example, in an optional embodiment, the force-applying end includes a second bearing seat 1224 and a second bearing 1225. A third steering box 1226 is provided between the second end of the third drive rod 1221 and the third coupling 1223. Specifically, during connection and disconnection... During the connection and disconnection of the track bridging device 100, the second bearing 1225 on the second bearing seat 1224 is rotated manually by turning a wrench, driving the third drive rod 1221 to rotate. Under the drive of the third steering box 1226, the horizontal rotation of the third drive rod 1221 is converted into the vertical rotation of the fourth drive rod 1222 by the connection of the third coupling 1223. Under the drive of the support frame 132 of the lifting assembly 130, the fixed bridging arm 1121 moves vertically. With the cooperation of the horizontal movement of the movable bridging arm 1111, the movable bridging arm 1111 and the fixed bridging arm 1121 are connected or disconnected. The track bridging device 100 does not require the assistance of a crane during the connection and disconnection process. Under the joint drive of the first drive unit 121 and the second drive unit 122, the movable bridging unit 111 and the fixed bridging unit 112 are driven to realize the connection and disconnection of the track bridging device 100, which is convenient to operate.

[0086] This invention provides a track bridging device for use in rail transport vehicles. It includes a bridging assembly and a drive assembly. The bridging assembly includes a fixed bridging unit and a movable bridging unit. The fixed bridging unit includes a fixed bridging arm disposed on one of two rail transport vehicles. The movable bridging unit includes a movable bridging arm movably disposed on the other of two rail transport vehicles. The drive assembly includes a first drive unit connected to the movable bridging arm and configured to drive the movable bridging arm to move towards the fixed bridging arm, thereby connecting the movable and fixed bridging arms to form a bridging track connecting the rails of the two rail transport vehicles. Thus, the track bridging device does not require a crane for connection and disconnection, making operation convenient.

[0087] Specifically, the present invention also provides a rail transport vehicle system 200, including two rail transport vehicles 210 and a track bridging device 100. The two rail transport vehicles 210 are a first rail transport vehicle 211 and a second rail transport vehicle 212. Specifically, the rail transport vehicle 210 is provided with a support column 213 for loading, unloading and placing rails 400. The support column 213 is provided with a track for guiding the trolley 300 to move. The trolley 300 is used to load, unload and adjust the rails 400. The trolley 300 moves on the track provided on the support column 213 and on the bridging track 500 between adjacent vehicle groups. During the loading and unloading of rails 400, the track bridging device 100 is connected to allow the trolley 300 to move between the first rail transport vehicle 211 and the second rail transport vehicle 212. During the transport of rails 400, the track bridging device 100 is disconnected to achieve normal transport of rails 400.

[0088] The overall working process of the track bridging device and rail transport vehicle system provided by this invention is as follows: During the loading and unloading of rails 400, the track bridging device 100 is connected to allow the guide trolley 300 to move between adjacent train sets. During the transport of rails 400, the track bridging device 100 is disconnected to achieve normal transport of rails 400. Specifically, during the connection process of the track bridging device 100, on the one hand, the first drive rod 1211 of the first drive unit 121 is rotated by manually turning a wrench, and on the other hand, the first coupling 1213, the second drive rod 1212, and the second coupling 1214 are connected. With the combined action of the lead screw 1215, the first connecting arm 1113, and the first rotating shaft connector 1114, the movable bridging arm 1111 moves horizontally to the left. Simultaneously, by manually turning a wrench, the third drive rod 1221 of the second drive unit 122 rotates. With the combined action of the third coupling 1223, the fourth drive rod 1222, and the support frame 132, the fixed bridging arm 1121 moves vertically upward. The combined action of the movable bridging arm 1111 moving horizontally to the left and the fixed bridging arm 1121 moving vertically upward achieves the alignment of the track bridging device 1. During the disconnection of the track bridging device 100, on the one hand, manually turning a wrench drives the first drive rod 1211 of the first drive unit 121 to rotate. With the combined action of the first coupling 1213, the second drive rod 1212, the second coupling 1214, the lead screw 1215, the first connecting arm 1113, and the first rotating shaft connector 1114, the moving bridging arm 1111 moves horizontally to the right. On the other hand, manually turning a wrench drives the third drive rod 1221 of the second drive unit 122 to rotate. With the combined action of the third coupling 1223 and the fourth drive rod 1214, the moving bridging arm 1111 moves horizontally to the right. With the combined action of rod 1222 and support frame 132, the fixed bridging arm 1121 moves vertically downward. With the combined action of the moving bridging arm 1111 moving horizontally to the right and the fixed bridging arm 1121 moving vertically downward, the track bridging device 100 is disconnected. The track bridging device 100 does not require a crane to connect or disconnect during the connection and disconnection process.
