Description

Technical Field

[0001] The utility model relates to the field of train derailers, in particular to a swing-bar type train derailer. Background Art

[0002] A train derailer is a railway safety device that is usually installed at a location where the rails are subject to greater stress and may break. Its function is to raise the wheels of the train when the rails need to be repaired, so that the train can be separated from the rails, thereby preventing accidents.

[0003] Existing train derailer generally translates linearly onto the train rails, and the train derailer of this mode is easy to cause obstacles between the head and the rails due to long-term non-use. These obstacles need to be cleaned before use, but the cleaning time is generally long, and the cleaning difficulty is large, and it is very difficult to clean them completely. Therefore, it is easy to cause the train derailer to have a large gap between the head and the rails when in use, causing the shaking margin to be large, affecting the reliability and stability of the train derailer.

[0004] And because it is necessary to slow down the train in advance when derailing, it is necessary to remind the train driver in advance to slow down the train to prevent accidents from causing casualties. However, the existing derailers do not have this function. Therefore, how to overcome the above-mentioned technical problems and defects has become a key problem to be solved. Utility Model Content

[0040] To secure the derailer. Figure 1-Figure 3 In this embodiment, a stripping head 2 that can be moved to the rail is arranged above the frame 1. The stripping head 2 is a mature existing mechanism and will not be described in detail here. A docking mechanism 3 that drives the stripping head 2 to move lateral is fixedly arranged on the frame 1. The docking mechanism 3 includes a fixing frame 31, and the fixing frame 31 is detachably mounted on the side of the train rail. Fixing plates 35 are fixedly arranged on both sides of the fixing frame 31, and the fixing plates 35 are fixed to the corresponding frame 1 by bolts. A groove 36 that fits with the bottom of the track is opened on the rear side of the fixing frame 31. The fixing frame 31 fits with the track through the groove 36, and the fixing frame 31 is installed on the frame 1 by bolts, so that the fixing frame 31 is fixedly arranged on the side of the track, so that the stripping head 2 is tightly connected to the track when derailment is required later.

[0041] In order to realize the removal of the head along a certain arc. In this embodiment, see Figure 1-Figure 3 A connecting plate 33 that can move obliquely downward is hingedly provided above the fixing frame 31 through a connecting rod unit 32. The connecting plate 33 is fixedly provided on the side of the stripping head 2 and its top end is always facing upward when it moves. The connecting rod unit 32 includes an upper swing rod 321, a lower swing rod 322 and a supporting top rod 323. Vertical plate portions 324 are provided on both sides of the fixing frame 31 in one piece or in a separate piece. The bottom end of the upper swing rod 321 is hingedly provided at the rear end of the vertical plate portion 324, and the bottom end of the lower swing rod 322 is hingedly provided at the front end of the vertical plate portion 324. The supporting top rod 323 is fixedly provided on both sides of the lower bottom surface of the connecting plate 33, and the two ends of the supporting top rod 323 are hingedly provided at the top of the upper swing rod 321 and the top of the lower swing rod 322, respectively. The upper swing rod 321, the lower swing rod 322, the supporting top rod 323 and the vertical plate portion 324 cooperate to form a four-bar mechanism, so that the top of the connecting plate 33 is always facing upward when moving, thereby ensuring that the stripping head 2 locks the track top and side in the working state without shaking margin, meeting reliability and stability. The hinge point of the upper swing rod 321 and the vertical plate portion 324 is higher than the hinge point of the lower swing rod 322 and the vertical plate portion 324. The connecting plate 33 can be moved to the lowest position inside the train rail.

[0042] To provide power for the movement of the head. Figure 1-Figure 3 , a driving unit 34 for driving the connecting plate 33 to move is fixedly arranged at the front end of the fixed frame 31. A power device 4 for driving the docking mechanism 3 to move is fixedly arranged on the frame body 1 outside the rail. The power device 4 can be a transfer machine, which is a mature existing technology and is not described here. The driving unit 34 includes a sliding plate 341, a driving rod 342 and a pulling plate 343, and the sliding plate 341 is fixedly arranged at the front end of the fixed frame 31. A sliding groove 344 is horizontally opened on the upper part of the sliding plate 341, and the driving rod 342 slides in the sliding groove 344 through a rotating shaft 345 fixedly arranged at its end. One end of the pulling plate 343 is sleeved on the rotating shaft 345, and the other end of the pulling plate 343 is hinged to the connecting rod unit 32. The other end of the driving rod 342 is a U-shaped opening structure, and the driving rod 342 is connected to the power device 4 through a through hole 19 opened on its side and penetrating the opening. The output end of the power device 4 is provided with a pull rod 9 in a threaded manner, and the free end of the pull rod 9 is fixedly connected to the through hole 19 at the end of the driving rod 342 by a bolt. The other end of the pull plate 343 is hingedly arranged with the middle part of the upper swing rod 321. The pull plate 343 drives the upper swing rod 321 to swing to realize the driving of the connecting rod unit 32. The other end of the pull plate 343 can also be hingedly arranged with the middle part of the supporting top rod 323. The pull plate 343 drives the supporting top rod 323 to swing to realize the driving of the connecting rod unit 32.

[0043] The driving rod 342 is driven by the power device 4 to move the rotating shaft 345 in the slide groove 344, so that the upper swing rod 321 or the supporting top rod 323 is pulled by the rotating shaft 345 to swing, so as to realize the driving of the connecting rod unit 32, and drive the connecting plate 33 to move the stripping head 2 obliquely upward to the train rail. When derailment is not needed, the stripping head 2 can be moved obliquely downward to the inside of the track without delaying the running of the train. The connection position of the driving rod 342 and the power device 4 is also provided with an insulating pad. Thereby, the connection position of the driving rod 342 and the power device 4 is insulated. It is prevented that the current on the rail causes damage to the power device 4.

[0044] In order to remind the train driver. Figure 1-Figure 3The frame 1 is also provided with a display mechanism 20 that rotates with the swing of the stripping head 2. The display mechanism 20 includes a rotating rod 10 that is rotatably arranged at the bottom of the front end of the fixed frame 31 and is perpendicular to the direction of the fixed frame 31. The end of the rotating rod 10 is fixedly provided with a swing rod 11 that is perpendicular to the direction of the rotating rod 10. The free end of the swing rod 11 is provided with a moving groove 12 that is sleeved on the rotating shaft 345 of the driving unit 34. The end of the rotating rod 10 is also fixedly provided with a support rod 13 that is perpendicular to the direction of the rotating rod 10. The display mechanism 20 also includes an identification plate 5 that is fixedly arranged at the end of the support rod 13. The identification plate 5 is a flat red plate. When it is necessary to remind the driver to slow down, the power device 4 pushes the driving rod 342 to move in the sliding groove 344 through the pull rod 9, and the side of the driving rod 342 moves synchronously in the moving groove 12, so that the swing rod 11 drives the rotating rod 10 to rotate on the fixed frame 31. At this time, the support rod 13 rotates with the rotating rod 10, so that the support rod 13 swings upward to remind the train driver to slow down.

[0045] The use method of the swing bar type train derailer of the utility model: first, dig a deep groove under the rail, and then place two frames 1 under the rail. Fix the frame 1 above the sleeper by the clamping plate 7 and the clamping plate 8 to avoid the end of the frame 1 from tilting or tilting due to its own stress or external influence, which affects the use of the derailer. Fix the frame 1 to the rail by the arc plate 6, so that the frame 1 and the rail are completely fitted, reducing the vibration generated during use. The fixed frame 31 is installed on the rail by the clamping block 37 and the groove 36, which is convenient for the subsequent head 2 to fit closely with the rail. Finally, the fixed plate 35 is arranged on the corresponding frame 1 by bolts, so as to fix the position of the derailer. The power equipment 4 is fixed to the frame 1 by bolts.

[0046] When derailment is not required, the derailing head 2 is located at the lowest position inside the rail, so as not to delay the normal running of the train, and the sign 5 is in a fallen state. When derailment is required, the output end of the power device 4 causes the driving rod 342 to push the rotating shaft 345 to move backward along the slide 344 through the pull rod 9, and the rotating shaft 345 pushes the pull plate 343 hinged thereto to move forward. At this time, the rear end of the pull plate 343 pushes the middle part of the upper swing rod 321, so that the upper swing rod 321 swings upward through its hinge point with the vertical plate portion 324. In this process, the top end of the upper swing rod 321 swings the support top rod 323 upward through its hinge point with the support top rod 323, and at the same time, the support top rod 323 drives the top end of the lower swing rod 322 to swing upward synchronously. Thus, the four-bar mechanism is formed by the cooperation of the vertical plate portion 324, the upper swing rod 321, the lower swing rod 322, and the supporting top rod 323, so that the supporting top rod 323 drives the connecting plate 33 to move and swing obliquely upwards and is always in a state of the top facing upwards. If the other end of the pull plate 343 is hinged with the supporting top rod 323, the rotating shaft 345 pushes the pull plate 343 hinged thereto to move forward. At this time, the rear end of the pull plate 343 pushes the middle part of the supporting top rod 323, thereby driving the upper swing rod 321 and the lower swing rod 322 to rotate on the vertical plate portion 324, and realizing the movement of the connecting plate 33. Thus, the stripping head 2 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. At this time, the support rod 13 rotates with the rotating rod 10 to realize the upward swing of the support rod 13 to remind the train driver to slow down.

[0047] Similarly, when the train derailment is not required, the driving rod 342 is pulled by the power device 4 to move backward in the slide slot 344. The driving rod 342 pulls the connecting frame hinged thereto to move forward, thereby separating the derailing head 2 from the rail through the connecting rod unit 32 and flipping it to the inner side of the rail. At the same time, the support rod 13 rotates with the rotating rod 10, realizing the downward swing of the support rod 13 and retracting the identification plate 5.

[0048] Embodiment 2: The same points as Embodiment 1 are not described in detail, and the difference is that:

[0049] In order to remind the train driver. Figure 4 and Figure 5, the indicating mechanism 20 includes a conversion box 14 fixedly arranged at the end of the frame 1. A gear fan 15 is rotatably arranged at the bottom end of the conversion box 14, and a mounting rod 16 is coaxially and vertically fixedly arranged at the top of the gear fan 15. The identification plate 5 is fixedly arranged at the top of the mounting rod 16. The identification plate 5 is two flat plates arranged perpendicular to each other, and the colors of the two flat plates are red and green respectively. A gear rod 17 meshing with the gear fan 15 is slidably arranged inside the conversion box 14, and the end of the gear rod 17 can extend out of the conversion box 14 and is fixedly connected to the drive unit 34 through a push rod 18 arranged at its end. The end of the push rod 18 can be fixedly arranged with one end of the rotating shaft 345, and the push rod 18 can also be fixedly arranged with the drive rod 342.

[0050] When the driver needs to be reminded to slow down, the power device 4 pushes the driving rod 342 to move in the slide slot 344 through the pull rod 9. At this time, the driving rod 342 drives the push rod 18 to move forward, thereby driving the gear rod 17 to move, and the gear rod 17 drives the mounting rod 16 to rotate through the gear fan 15, so that the red sign rotates to face the driver. Similarly, when derailment is not required, the power device 4 pulls the driving rod 342 to move in the slide slot 344 through the pull rod 9. Thereby, the green sign turns to the driver.
