Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] Example like Figures 1-10 As shown, a self-lifting obstacle avoidance device for a single-track railcar includes a trolley body 9 and a lifting mechanism. The lifting mechanism is carried on the trolley and uses the onboard lifting mechanism to lift itself to achieve passing on the single-track rail 2.
[0022] like Figures 1-10 As shown, the trolley body 9 is equipped with a seat 92 and an operating table 93. A lifting mechanism is provided on one side of the trolley body 9. The lifting mechanism is mounted on the trolley body 9 in a height-adjustable manner and is movably connected to the trolley body 9. A turntable mechanism is rotatably provided on the bottom side of the lifting mechanism.
[0023] like Figures 1-10 As shown, the trolley body 9 travels on track 2 via track wheels 91. Track 2 is supported on concrete sleepers 1. Lifting foundations are set on the concrete sleepers 1 outside the track 2. The lifting foundations are evenly distributed on a track 2, for example, one lifting foundation every 50m or 100m. The lifting mechanism can be lowered, and the turntable mechanism can be detachably connected to the lifting foundation, thereby connecting the lifting mechanism, turntable mechanism, and lifting foundation into one unit, transferring the lifting force of the entire system to the concrete sleepers 1 and the underlying foundation.
[0024] After the turntable mechanism is connected to the hoisting foundation, the turntable mechanism can drive the hoisting mechanism and the trolley body 9 to rotate synchronously to the outside of the track 2, thereby realizing the operation of avoiding passing vehicles.
[0025] like Figures 1-3 As shown, when the trolley body 9 is traveling normally on the track 2, the turntable mechanism is away from the hoisting foundation, and the turntable mechanism and the hoisting mechanism are located on one side of the trolley body 9.
[0026] like Figures 4-6 As shown, when preparing to meet another vehicle, by controlling the lowering of the lifting mechanism and making the turntable mechanism detachably connected to the lifting foundation, a stable connection between the lifting foundation, the turntable mechanism, and the lifting mechanism is achieved.
[0027] like Figures 7-9 As shown, after the turntable mechanism is connected to the hoisting foundation, the turntable mechanism can drive the hoisting mechanism and the trolley body 9 to rotate synchronously to the outside of the track 2. Specifically, after the turntable mechanism is connected to the hoisting foundation, the hoisting mechanism extends to control the trolley body 9 to rise a certain distance, making it suspended in the air, that is, to let the track wheel 91 leave the track 2; then, the turntable mechanism is used to control the hoisting mechanism and the trolley body 9 to rotate synchronously to the designated outside to achieve meeting.
[0028] When this structure is simple and ingenious, it allows for stable and convenient passing operations. The onboard lifting mechanism can be used to lift the vehicle itself to facilitate passing. The lifting mechanism is stably connected to the lifting foundation, ensuring the stability of the entire system. This simplifies the vehicle itself and significantly improves the system's safety and feasibility.
[0029] like Figures 1-10 As shown, the lifting mechanism includes a column 6 and a base 5 set on the bottom side of the column 6. A guide tube 61 is set in the middle of the column 6. A guide seat 7 is set on one side of the trolley body 9. A guide hole 71 is opened on the upper side of the guide seat 7. The guide tube 61 is slidably set in the inner guide hole 71 of the guide seat 7 to realize the lifting limit of the column 6.
[0030] Furthermore, a guide protrusion is provided on one side of the guide tube 61, and a sliding groove that mates with the guide protrusion is provided on the inner wall of the guide hole 71. Similar to the fit of a keyway and a key, this ensures that the column 6 can only move up and down relative to the guide seat 7, and cannot rotate relative to it. In other words, the two can only rotate synchronously.
[0031] like Figures 1-10 As shown, the turntable mechanism includes a turntable 43 and a mounting base 4 disposed on the bottom side of the turntable 43. The turntable 43 is rotatably mounted on the outer wall of the base 5 via bearings. A motor base 51 is disposed on the base 5, and a rotary motor 52 is fixed on the motor base 51. A first gear 53 is connected to the output shaft of the rotary motor 52. A second gear 44 is fixed on the outer wall of the turntable 43, and the first gear 53 and the second gear 44 are meshed together. With this structure, after the bottom side of the turntable mechanism is fixed by the mounting base 4, the upper lifting mechanism can be controlled to rotate. In other words, after the bottom side of the turntable mechanism is fixed by the mounting base 4, the upper lifting mechanism and the trolley body 9 can be controlled to rotate synchronously to achieve collision avoidance.
[0032] like Figures 1-10 As shown, the hoisting foundation includes a pre-set steel plate 3, and the mounting base 4 is detachably connected to the pre-set steel plate 3.
[0033] Furthermore, a first bolt 11 is pre-embedded on the concrete sleeper 1, and a pre-set steel plate 3 is sleeved on the first bolt 11 through the connecting hole 32 and connected by the first nut 12, so as to realize the detachable connection between the pre-set steel plate 3 and the concrete sleeper 1.
[0034] Furthermore, a number of first mounting cylinders 41 are symmetrically arranged on the mounting base 4, and a number of second mounting cylinders 31 are arranged on the preset steel plate 3; when the bottom side of the mounting base 4 is attached to the preset steel plate 3, the first mounting cylinders 41 and the second mounting cylinders 31 are connected by inserting pins 42, so as to realize the convenient assembly and disassembly of the mounting base 4 and the preset steel plate 3.
[0035] like Figures 1-10 As shown, a first hydraulic cylinder 8 is hinged to the upper side of the guide seat 7, and a guide cylinder 73 is provided on the lower side of the guide seat 7. The outer wall of the first hydraulic cylinder 8 is tightly pressed against the inner wall of the guide cylinder 73 to achieve a limiting position. A first piston rod 81 is provided inside the first hydraulic cylinder 8, and a hinge part 62 is provided on the bottom side of the column 6. The bottom end of the first piston rod 81 is hinged to the hinge part 62 on the bottom side of the column 6. This structure can control the extension and retraction of the first hydraulic cylinder 8 to realize the height adjustment of the lifting mechanism and the height adjustment of the turntable mechanism. When the first hydraulic cylinder 8 extends, it controls the turntable mechanism to descend and connect with the lifting foundation. Then the first hydraulic cylinder 8 continues to extend. Since the turntable mechanism descends and connects with the lifting foundation, its position is fixed, so it can control the trolley body 9 to be lifted and suspended in the air. Finally, the turntable mechanism drives the trolley body 9 to rotate to avoid passing vehicles. When the rotary motor 52 rotates, it drives the column 6 to rotate. Since the column 6 and the guide seat 7 are connected, they can drive the guide seat 7 and the trolley body 9 to rotate.
[0036] Furthermore, two limiting rods 72 are symmetrically arranged on the bottom side of the guide seat 7. When the first hydraulic cylinder 8 retracts, the base 5 and the turntable 43 are positioned between the two limiting rods 72 to shield and protect the turntable mechanism.
[0037] Furthermore, a mounting hole 63 is provided on the upper side of the column 6, and a canopy mechanism is detachably mounted on the upper side of the column 6 through the mounting hole 63. The canopy mechanism is used for sun and rain protection. In this way, the canopy mechanism is mounted on the column 6, and the height of the canopy mechanism can be adjusted by extending and retracting the first hydraulic cylinder 8. The overall structure is simple, ingenious, and easy to implement.
[0038] In this invention, the trolley body 9 is either a manually driven rail bicycle or an electrically driven rail trolley. Both adopt existing technical structures, generally as follows: For a manually driven rail bicycle, the drive mechanism is completely similar to a bicycle, including pedals / cranks, sprockets / chains, etc. For an electrically driven rail trolley, it includes a drive motor, a power battery, a controller, acceleration and control devices, etc.
[0039] In this invention, the train is used for passing on a single-line track 2, and passing is achieved by hoisting. Therefore, the overall trolley body 9 structure needs to adopt a lightweight design. In addition to the main structure using high-strength aluminum alloy, non-load-bearing components use engineering plastics or carbon fiber composite materials. The lightweight design is maximized while ensuring safety and reliability.
[0040] like Figures 11-15 As shown, in this utility model, in addition to being connected to the hoisting foundation, it can also be directly connected to the track 2, which makes disassembly and assembly easier and eliminates the need for pre-set steel plates 3.
[0041] Specifically, the hoisting foundation also includes a positioning plate 10, which is connected to the bottom side of the turntable 43. The positioning plate 10 is roughly T-shaped and is inserted between two concrete sleepers 1 to achieve positioning and installation. The positioning plate 10 is supported on the two concrete sleepers 1 as a whole.
[0042] The positioning plate 10 has an operating groove 101 and a sliding groove 102 communicating with the operating groove 101. An L-shaped clamping plate 103 is slidably disposed in the sliding groove 102, and the L-shaped clamping plate 103 can be adjusted in position by moving up, down, left, right, and horizontally. The L-shaped clamping plate 103 is provided with a clamping groove 104 for clamping onto the bottom side of the track 2. A first tightening screw 105 is threadedly connected to the bottom side of the positioning plate 10, and the first tightening screw 105 abuts upward against the bottom side of the L-shaped clamping plate 103. Second tightening screws 106 are threadedly connected to both sides of the operating groove 101, and the second tightening screws 106 abut laterally against the side wall of the concrete sleeper 1.
[0043] Before installing the positioning plate 10, the L-shaped clamping plate 103 is stored in the operating slot 101. When installing the positioning plate 10, the first hydraulic cylinder 8 extends to control the positioning plate 10 to descend until it is supported on the concrete sleeper 1. Then, the L-shaped clamping plate 103 is pushed to the bottom side of the rail 2. Then, the first tightening screw 105 is rotated to drive the L-shaped clamping plate 103 to move upward, so that the L-shaped clamping plate 103 is locked into the bottom side of the guide rail 2 through the slot 104. Then, the second tightening screw 106 is rotated to completely fix the positioning plate 10. The passing operation can then begin.
[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
