[0030] Such as Figures 1-6As shown in the figure, the present embodiment provides an automatic commissioning device for a third-rail current collector of a rail vehicle, which includes a third-rail current collector 1 and a commissioning machine 2. The commissioning machine 2 is wrapped around the outer end of the third-rail current collector 1. The commissioning machine 2 includes a linkage frame 3 and two positioning frames 6. An inner groove 4 is provided at the inner end of the linkage frame 3. A connecting rod 18 is provided at the inner end of the inner groove 4. A linkage spring 5 is provided at the outer end of the connecting rod 18. Two rotating shafts 7 are provided at the upper end of the commissioning machine 2. Rotating rods 8 are respectively provided at the outer ends of the two rotating shafts 7. A sliding groove 10 is provided at the inner end of the positioning frame 6. A sliding rod 9 is provided at the inner end of the sliding groove 10. A positioning rod 11 is provided at the outer end of the sliding rod 9. An embedded groove 12 is provided at the inner end of the positioning rod 11. An electric push rod 13 is provided at the inner end of the embedded groove 12. A foreign object handling rod 14 is wrapped around the outer end of the electric push rod 13.
[0031] The upper end of the linkage frame 3 of the commissioning machine 2 is fixed to the fixed part of the third-rail current collector 1 through a connecting piece, which facilitates the movement of the third-rail current collector 1 along the inside of the commissioning machine 2.
[0032] The linkage frame 3 is fixed at the rear end of the commissioning machine 2. There is a fixed connection between the linkage frame 3 and the rotating shaft 7. There is a movable connection between the outer end of the rotating shaft 7 and the rotating rod 8. The outer end of the rotating rod 8 is fixedly connected to the fixed frame. The sliding grooves 10 are respectively embedded and installed at the upper and lower ends of the positioning frame 6. There is a fixed connection between the inner end of the sliding groove 10 and the sliding rod 9. There is a sliding connection between the inner end of the sliding rod 9 and the positioning rod 11. The embedded groove 12 is embedded and installed at the inner end of the positioning rod 11. There is a movable connection between the electric push rod 13 and the embedded groove 12. There is a movable connection between the outer end of the electric push rod 13 and the foreign object handling rod 14.
[0033] A spring is wrapped around the outer end of the sliding rod 9. The fixed end of the spring is fixed in the sliding groove 10. The movable end of the spring is fixed to the outer end of the positioning rod 11. There is a transmission part between the movable end of the spring and the positioning rod 11. The positioning rod 11 is attached to the outer surfaces at both ends of the third-rail current collector 1. A touch module is attached to the positioning rod 11, which is used to sense the position of foreign objects. There is a signal connection between the touch module and the electric push rod 13. The rear end of the third-rail current collector 1 is in contact with the connecting rod 18. The outer end of the connecting rod 18 is slidably connected to the inner groove 4.
[0034] When the third-rail current collector 1 is in the charging state, it is in contact with the electric rail. During this process, if there is a foreign object clamped between the electric rail and the third-rail current collector 1, the third-rail current collector 1 moves backward along the commissioning machine 2, pushing the connecting rod 18 to move backward along the inner groove 4 and compressing the linkage spring 5. At this time, the positioning rods 11 at both ends of the third-rail current collector 1 slide along the sliding groove 10 under the control of the spring and the transmission part until the touch module at the outer end of the positioning rod 11 touches the foreign object. At this time, the touch module sends an instruction to the electric push rod 13, driving the foreign object handling rod 14 to push downward to remove the foreign object. After the touch module can no longer contact the foreign object, it sends an instruction to the transmission part to drive the positioning rod 11 to move back to the initial position.
[0035] The transmission parts are made based on the principle of the sliding rod 9 mechanism of the prior art and are used to drive the positioning rod 11 to slide along the upper and lower chutes 10 according to signals.
[0036] As Figures 4-5 shown, as a preferred embodiment, on the basis of the above method, further, a notch frame 15 and a linkage rod 16 are provided between the positioning frames 6. A buckle plate 17 is provided at the outer end of the notch frame 15. Grooves are provided at the upper ends of the two groups of positioning frames 6, and the grooves are embedded in the upper ends of the left group of positioning frames 6. A fixed connection is established between the inside of the grooves and the linkage rod 16. The notch frame 15 slides along the linkage rod 16, and an activity connection is established between the right end of the notch frame 15 and the buckle plate 17. The buckle plate 17 is fixed in the groove of the right group of positioning frames 6 through screws.
[0037] When installing and debugging the machine 2, the upper end of the linkage frame 3 of the debugging machine 2 is fixed to the fixed part of the third-rail current collector 1 through a connecting piece, and then the rotating rod 8 and the positioning frame 6 are driven to rotate through the rotating shaft 7, so as to push the groove on the positioning frame 6 to align, push the notch frame 15 to move to the right along the linkage rod 16, and then fix the buckle plate 17 to the outer end of the notch frame 15 through screws to fix the notch frame 15.
[0038] When this application is in use: Install the debugging machine 2 at the outer end of the third-rail current collector 1. When the third-rail current collector 1 contacts the electric rail for charging and a foreign object is clamped between the third-rail current collector 1 and the electric rail, at this time, the third-rail current collector 1 moves backward along the debugging machine 2, pushing the connecting rod 18 to move backward along the inner groove 4 and compressing the linkage spring 5. At this time, the positioning rods 11 at both ends of the third-rail current collector 1 slide along the chute 10 under the control of the spring and the transmission parts until the touch module at the outer end of the positioning rod 11 touches the foreign object. At this time, the touch module sends an instruction to the electric push rod 13 to drive the foreign object handling rod 14 to push downward to remove the foreign object. After the touch module can no longer contact the foreign object, it sends an instruction to the transmission parts to drive the positioning rod 11 to move back to the initial position.
