AI Technical Summary
The existing turnout system cannot meet the track trolley's track changing requirements in a small space. Traditional switch rails need to be long enough to achieve elastic deformation, making it impossible to complete track switching in the limited space of a steel production workshop.
The device employs a small-radius track changing mechanism, which includes a first track, a second track, an arc track, a moving component, a power component, and a transition component. The power component drives the moving component to move between different positions, thereby causing the transition component to rotate and enabling the track trolley to change tracks in different directions.
The track trolley can change tracks in short and limited areas, reducing the space occupied by the track changing device, avoiding the need for external bending of the switch rail, and realizing a small-scale track changing process.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transportation track technology, specifically relating to a small-arc track changing device. Background Technology
[0002] In steel ladle transportation, railcars are commonly used for transfer. Steel rails are laid on the ground, and the railcar travels along these rails, transporting the steel ladles to the designated location according to the rail direction. However, during steel ladle transportation, the railcar sometimes needs to move from one rail to another, requiring a track change (i.e., a turn). In existing technology, when a supporting train, vehicle, or other mobile equipment needs to change track, a switch system is used. For example, in train track changing, the switch system uses point rails to switch tracks, allowing the train to travel from one track to another.
[0003] However, while the switch rails in a turnout system do not permanently bend during movement, they undergo elastic deformation to adapt to track switching requirements. For example, during switch machine traction, the connecting rod frame structure allows the switch rails to bend moderately to accommodate track changes. Although this method enables track changes, because the switch rails are made of the same high-strength material as the rails, sufficient length is required for elastic deformation. However, modern steel production workshops have limited space, and the turning space of track trolleys is small, resulting in a small turning radius. Therefore, the switch rails in traditional turnout systems cannot bend when their length is insufficient, thus failing to meet the requirements for track changes. Utility Model Content
[0004] Based on this, this application provides a small-radius track changing device to solve the technical problem that the existing turnout system cannot achieve track changing in a small space and short distance.
[0005] The technical solution to the above-mentioned technical problems in this application is as follows:
[0006] A small-radius track changing device, comprising:
[0007] First track;
[0008] The second track is provided at an interval from the first track and both are along the first direction of movement;
[0009] Curved tracks are used to provide a second direction of motion;
[0010] A movable component is disposed between the first track and the second track, and is provided with a first docking part and a second docking part;
[0011] A power component is disposed on the moving component and is used to drive the moving component to move between a first position and a second position. In the first position, the first docking part connects the first track and the second track, and in the second position, the second docking part connects the first track and the arc track.
[0012] A transition component is rotatably disposed at the intersection of the second track and the arc track, and is driven to rotate by a moving component. In a first position, the transition component rotates to a first direction of motion, and in a second position, the transition component rotates to a second direction of motion.
[0013] Preferably, the first track comprises two parallel first rails.
[0014] Preferably, the second track includes two parallel second rails, which are on the same straight line as the first rails, and the first docking part connects the two first rails and the two second rails at the first position.
[0015] Preferably, the curved track includes two curved steel rails, and the interval between the two curved steel rails is consistent with the interval between the two first steel rails. The second docking part at the second position connects the two first steel rails and the two curved steel rails.
[0016] Preferably, the moving component includes a base and a sliding plate slidably connected to the base, the base being disposed between the first track and the second track, and both the first docking portion and the second docking portion being disposed on the sliding plate.
[0017] Preferably, the first docking portion includes a straight rail, which is disposed on the slide plate, and the straight rail connects the first track and the second track at a first position.
[0018] Preferably, the second docking portion includes an arc-shaped steel rail, which is disposed on the slide plate, and at a second position, the arc-shaped steel rail connects the first track and the arc track.
[0019] Preferably, the power assembly includes a hydraulic cylinder connected to the base, the slide plate connected to the hydraulic rod of the hydraulic cylinder, and the hydraulic cylinder drives the slide plate to move between a first position and a second position.
[0020] Preferably, the transition component includes a turntable, a toothed ring disposed on the outside of the turntable, and a rack meshing with the toothed ring. The rack is disposed on a slide plate, and the turntable is provided with a transition rail. In a first position, the turntable drives the transition rail to connect with the second track, and in a second position, the turntable drives the transition rail to connect with the arc track.
[0021] Compared with the prior art, this application has at least the following advantages:
[0022] This application provides a small-arc track changing device. In practical applications, the power component drives the moving component to move horizontally. When the first docking part moves to the first position with the moving component, the first docking part connects the first track and the second track. At the same time, when the moving component moves, it drives the transition component to connect the first docking part and the second track. At this time, the track trolley can move along the first track and the second track in the first direction. When the track trolley needs to move along the second direction, a track changing process is required to position the track trolley on the first track. Then, the power component drives the moving component to move, causing the second docking part to move between the first track and the arc track, and aligning the second docking part with the first track. At this time, the second docking part will also align with the arc track. The moving component is then in the second position. While the moving component moves, the transition component can rotate to the position where it connects with the arc track. At this time, the track trolley can move along the first track to the arc track, completing the movement in the second direction and completing the track changing process from the first direction to the second direction. It can realize the track trolley changing process in a short and limited area. Compared with the traditional turnout system, it does not require external force to "bend" the switch rail, reducing the area occupied by the entire track changing device and realizing track changing in a small range.

[0031] Please refer to Figures 1 to 4 In one specific embodiment of this application,
[0032] A small-radius track changing device, comprising:
[0033] First track 100;
[0034] The second track 200 is provided at intervals between the first track 100 and the second track 200 and both are along the first direction of movement;
[0035] Curved track 300 is used to provide a second direction of motion;
[0036] The movable component 400 is disposed between the first track 100 and the second track 200, and is provided with a first docking part 410 and a second docking part 420;
[0037] A power component 500 is disposed on the moving component 400 and is used to drive the moving component 400 to move between a first position and a second position. In the first position, the first docking part 410 connects the first track 100 and the second track 200, and in the second position, the second docking part 420 connects the first track 100 and the arc track 300.
[0038] A transition component 600 is rotatably disposed at the intersection of the second track 200 and the arc track 300, and is driven to rotate by the moving component 400. In a first position, the transition component 600 rotates to a first direction of motion, and in a second position, the transition component 600 rotates to a second direction of motion.
[0039] Wherein: the first track 100, the second track 200, the curved track 300, the first docking part 410, and the second docking part 420 can be steel rails, slide rails, or other facilities capable of guiding the mobile device (railcar) forward. The moving component 400 can be a sliding plate, a slider, or other devices and facilities capable of translation. The power component 500 can be a telescopic rod, a rack and pinion gear, or other devices and facilities used to drive the movement of an object. The transition component 600 can be a support, a bridge, or other devices and facilities used to pave the transition for the tires.
[0040] In practical applications, the first track 100, the second track 200, and the curved track 300 are all erected on the ground using sleepers or related foundations. The track trolley is positioned on the first track 100 or the second track 200. The power component 500 drives the moving component 400 to move horizontally. When the first docking part 410 moves to the first position along with the moving component, it connects the first track 100 and the second track 200. Simultaneously, the movement of the moving component 400 drives the transition component 600 to connect the first docking part 410 and the second track 200, i.e., rotate to the first direction of movement. At this time, the track trolley can move along the first track 100 and the second track 200 in the first direction of movement. When the track trolley needs to move along the second direction... During movement, a track-changing process is required. When the trolley is positioned on the first track 100, the power component 500 drives the moving component 400 to move, causing the second docking part 420 to move between the first track 100 and the curved track 300, aligning the second docking part 420 with the first track 100. At this time, the second docking part 420 will also align with the curved track 300. The moving component 400 is now in the second position. As the moving component 400 moves, the transition component 600 can rotate to the position where it connects with the curved track 300, which is the second direction of movement. At this point, the trolley can move along the first track 100 onto the curved track 300, completing the movement in the second direction of movement and completing the track-changing process from the first direction of movement to the second direction of movement.
[0041] The above method enables the track trolley to change tracks in short and limited areas. Compared to traditional turnout systems, it does not require external force to "bend" the switch rails, thus reducing the area occupied by the entire track-changing device and enabling track changing in a small range.
[0042] Specifically, an embodiment is provided for the first track 100 in the above process:
[0043] The first track 100 includes two parallel first rails 110.
[0044] Two parallel first steel rails 110 are laid in the steel production workshop, and the rail trolley can travel and move along the two parallel first steel rails 110 to transport the steel ladle and other raw materials carried on the rail trolley.
[0045] Specifically, an embodiment is provided for the second track 200 in the above process:
[0046] The second track 200 includes two parallel second rails 210, which are on the same straight line as the first rail 110. At the first position, the first docking part 410 connects the two first rails 110 and the two second rails 210.
[0047] Two parallel second rails 210 are laid in the production workshop and aligned with two parallel first rails 110 respectively. When the moving component 400 moves, it can drive the first docking part 410 to move between the second rails 210 and the first rails 110 to complete the rail connection. This allows the rail trolley to move from the first rail 110 to the second rail 210. The starting end of the first rail 110 is set at the heating furnace, which allows the rail trolley to move the ladle to the side of the heating furnace for receiving molten steel. The end point of the second rail 210 can be the end point of the transfer route or the position where the ladle is cast. Thus, the rail trolley transports the ladle in the first direction of movement formed by the first rail 110 and the second rail 210.
[0048] Specifically, an embodiment of the curved track 300 in the above process is provided:
[0049] The curved track 300 includes two curved steel rails 310, and the interval between the two curved steel rails 310 is consistent with the interval between the two first steel rails 110. The second docking part 420 at the second position connects the two first steel rails 110 and the two curved steel rails 310.
[0050] Two curved steel rails 310 are laid in the workshop and located on one side of the first steel rail 110. When the second docking part 420 is connected, the rail trolley can move along the first steel rail 110 to the curved steel rail 310, thereby enabling the rail trolley to complete the second direction of movement. This completes the change of direction and track-changing transportation of the rail trolley within the workshop.
[0051] Specifically, an embodiment is provided for the moving component 400 in the above process:
[0052] The moving component 400 includes a base 430 and a sliding plate 440 slidably connected to the base 430. The base 430 is disposed between the first track 100 and the second track 200. The first docking part 410 and the second docking part 420 are both disposed on the sliding plate 440.
[0053] The base 430 is connected to the workshop floor. The power component 500 can be connected to the base 430 by means of bolts, concrete embedding, etc. Then, the power component 500 drives the slide plate 440 to move on the base 430. When a track change is required, the power component 500 drives the slide plate 440 to move, so that the slide plate 440 drives the first docking part 410 and the second docking part 420 connected to it to move, thus completing the connection with the first track 100.
[0054] Specifically, an embodiment is provided for the first docking part 410 in the above process:
[0055] The first docking part 410 includes a straight rail 411, which is disposed on the slide plate 440. In a first position, the straight rail 411 connects the first track 100 and the second track 200.
[0056] The straight rail 411 is connected to the slide plate 440. When the slide plate 440 moves to align the straight rail 411 with the first rail 110 and the second rail 210, the first rail 110 and the second rail 210 can be connected, allowing the track trolley to move from the first rail 110 to the straight rail 411, and then from the straight rail 411 to the second rail 210.
[0057] Specifically, an embodiment is provided for the second docking unit 420 in the above process:
[0058] The second docking part 420 includes an arc-shaped steel rail 421, which is disposed on the slide plate 440. At a second position, the arc-shaped steel rail 421 connects the first track 100 and the arc track 300.
[0059] The arc-shaped steel rail 421 is connected to the sliding plate 440, and its structure is as follows: Figures 1 to 4 As shown, the structure is arc-shaped, and its purpose is to guide the track trolley onto the arc-shaped track 310 after the first rail 110 is connected, and guide the track trolley to move along the second direction of movement.
[0060] Specifically, an embodiment of the power component 500 in the above process is provided:
[0061] The power assembly 500 includes a hydraulic cylinder 510, which is connected to the base 430. The slide plate 440 is connected to the hydraulic rod of the hydraulic cylinder 510. The hydraulic cylinder 510 drives the slide plate 440 to move between a first position and a second position.
[0062] The hydraulic cylinder 510 is connected to the hydraulic station. When the hydraulic cylinder 510 controls the hydraulic rod to extend and retract, it can drive the slide plate 440 to move on the base 430, realize the movement conversion between the first position and the second position, and thus realize the track-changing connection process between the first docking part 410 and the second docking part 420.
[0063] Specifically, an embodiment of the transition component 600 in the above process is provided:
[0064] The transition component 600 includes a turntable 610, a toothed ring 620 disposed on the outside of the turntable 610, and a rack 640 meshing with the toothed ring 620. The rack 640 is disposed on the slide plate 440. The turntable 610 is provided with a transition rail 630. In a first position, the turntable 610 drives the transition rail 630 to connect with the second track 200. In a second position, the turntable 610 drives the transition rail 630 to connect with the arc track 300.
[0065] The turntable 610 is rotatably connected to the outside of the base 430. A side hole 431 is provided on the side of the base 430 near the turntable 610. A slide rod 441 is provided on the slide plate 440, and a rack 640 is connected to the end of the slide rod 441. Since the curved tracks 300 are all laid on the ground using sleepers, see reference... Figure 1 The bottom of the arc-shaped rail 310 between the transition component 600 and the first docking part 410 is covered with sleepers, so there is a space reserved between the bottom of the arc-shaped rail 300 and the ground for the rack 640 to move. When the slide plate 440 slides on the base 430, the slide rod 441 can move in the side hole 431, so that when the rack 640 moves, it engages with the toothed ring 620. The toothed ring 620 drives the turntable 610 to rotate, so that the transition rail 630 can be connected between the second rail 200 (second rail 210) or between the arc-shaped rail 300 (arc-shaped rail 310). The transition and connection can be completed at the intersection of the second rail 200 and the arc-shaped rail 300, so that the tires of the rail trolley can travel smoothly along the second rail 200 and the arc-shaped rail 300.
[0066] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
