[0023] See also Figure 1-Figure 3, the derailing head flip docking mechanism based on the train derailer of the present embodiment can move the derailing head along a certain arc to the track, reduce the difficulty of cleaning the track, and form a four-bar mechanism at the same time, so that the top of the derailing head is always facing upward when the derailing head moves, thereby ensuring that the derailing head locks the track above and on the side in the working state, without shaking margin, and meets reliability and stability. In the present embodiment, it mainly includes, including a fixed frame 1, and the fixed frame 1 is detachably mounted on the side of the train rail. Both sides of the fixed frame 1 are fixedly provided with a fixed plate 5, and the fixed plate 5 is fixed to the corresponding frame body by bolts. The rear side of the fixed frame 1 is provided with a groove 6 that fits the bottom of the track. The fixed frame 1 fits the track through the groove 6, and the fixed frame 1 is installed on the frame body by bolts, so that the fixed frame 1 is fixedly arranged on the side of the track, so that the derailing head is tightly connected to the track when derailment is required later.

[0024] In order to realize the movement of the stripped head, it is convenient to realize the derailment and storage. Figure 1-Figure 3 In this embodiment, a connecting plate 3 that can move obliquely downward is hingedly provided on the upper part of the fixing frame 1 through a connecting rod unit 2. The connecting plate 3 is fixedly provided on the side of the stripping head and its top is always facing upward when it moves. The connecting rod unit 2 includes an upper swing rod 21, a lower swing rod 22 and a supporting top rod 23. Vertical plate portions 24 are integrally or separately provided on both sides of the fixing frame 1. The bottom end of the upper swing rod 21 is hingedly provided at the rear end of the vertical plate portion 24, and the bottom end of the lower swing rod 22 is hingedly provided at the front end of the vertical plate portion 24. The supporting top rod 23 is fixedly provided on both sides of the lower bottom surface of the connecting plate 3, and the two ends of the supporting top rod 23 are respectively hingedly provided with the top of the upper swing rod 21 and the top of the lower swing rod 22. The upper swing rod 21, the lower swing rod 22, the supporting top rod 23 and the vertical plate portion 24 cooperate to form a four-bar mechanism, so that the top of the connecting plate 3 is always facing upward when it moves, thereby ensuring that the stripping head locks the track top and side in the working state without shaking margin, meeting reliability and stability. The hinge point between the upper swing arm 21 and the vertical plate portion 24 is higher than the hinge point between the lower swing arm 22 and the vertical plate portion 24. The connecting plate 3 can be moved to the lowest position inside the train rail.

[0025] In order to provide power for the movement of the stripping head. In this embodiment, see Figure 1-Figure 3The front end of the fixed frame 1 is fixedly provided with a driving unit 4 for driving the connecting plate 3 to move. The driving unit 4 includes a sliding plate 41, a driving rod 42 and a pulling plate 43, and the sliding plate 41 is fixedly provided at the front end of the fixed frame 1. A sliding groove 44 is horizontally provided on the upper part of the sliding plate 41, and the driving rod 42 slides in the sliding groove 44 through a rotating shaft 45 fixedly provided at its end. One end of the pulling plate 43 is sleeved on the rotating shaft 45, and the other end of the pulling plate 43 is hingedly provided with the connecting rod unit 2. The other end of the driving rod 42 is in a U-shaped opening structure, and the driving rod 42 is connected to an external power device through a through hole 46 provided on its side and penetrating the opening. The other end of the pulling plate 43 is hingedly provided with the middle part of the upper swing rod 21. The upper swing rod 21 is driven to swing by the pulling plate 43 to realize the driving of the connecting rod unit 2. The driving rod 42 is driven by the power device to move in the slide groove 44 through the rotating shaft 45, so that the upper swing rod 21 is pulled to swing through the rotating shaft 45, so as to realize the driving of the connecting rod unit 2, and drive the connecting plate 3 to move the derailed head obliquely upward to the train rail. When derailment is not needed, the derailed head can be moved obliquely downward to the inside of the track without delaying the train running. The connection position of the driving rod 42 and the power device is also provided with an insulating pad. Thus, the connection position of the driving rod 42 and the power device is insulated. It is prevented that the current on the rail causes damage to the power device. The driving rod 42 is connected to the power device by inserting a bolt into the through hole 46.

[0026] The method of using the derailing head flip docking mechanism based on the train derailer of the utility model is as follows: first, the fixing frame 1 is fitted with the track through the groove 6 on the rear side thereof, and the fixing plate 5 is fixed to the frame body by bolts, so as to fix the position of the fixing frame 1.

[0027] When the train needs to be derailed, the driving rod 42 is driven by the power device to push the rotating shaft 45 to move backward along the slide 44, and the rotating shaft 45 pushes the pull plate 43 hinged thereto to move forward. At this time, the rear end of the pull plate 43 pushes the middle part of the upper swing rod 21, so that the upper swing rod 21 swings upward through the hinge point between it and the vertical plate portion 24. In this process, the top of the upper swing rod 21 swings the support top rod 23 upward through the hinge point between it and the support top rod 23, and at the same time, the support top rod 23 drives the top of the lower swing rod 22 to swing upward synchronously. Thus, the vertical plate portion 24, the upper swing rod 21, the lower swing rod 22, and the support top rod 23 cooperate to form a four-bar mechanism, so that the support top rod 23 drives the connecting plate 3 to move and swing obliquely upward, and is always in a state of the top facing up. Thus, the derailing head is driven to be close to the top and side of the track, so that there is no shaking margin when the train derails, and reliability and stability are met.

[0028] Similarly, when the train does not need to be derailed, the driving rod 42 is pulled by the power device to move the rotating shaft 45 backward in the slide groove 44. The rotating shaft 45 pulls the pull plate 43 hinged thereto to move forward, thereby separating the derailing head from the track through the four-bar mechanism and moving it to the inner side of the track without delaying the normal running of the train.

[0029] Embodiment 2: The same points as Embodiment 1 are not described in detail, and the difference is that:

[0030] In order to provide power for the movement of the stripping head, in this embodiment, the other end of the pull plate 43 is hinged to the middle of the support top rod 23. The pull plate 43 drives the support top rod 23 to swing, thereby driving the connecting rod unit 2. When the rotating shaft 45 moves in the slide groove 44, the pull plate 43 drives the support top rod 23 to move, thereby driving the upper swing rod 21 and the lower swing rod 22 to rotate on the vertical plate portion 24, thereby realizing the movement of the connecting plate 3.
