[0039] An embodiment of the present application discloses an intelligent outrigger and a method for a rail grinding vehicle to get on and off a flat car.
[0040] In a first aspect, an embodiment of the present application discloses an intelligent outrigger.
[0041] Referring to Figure 1 and Figure 2 , an intelligent outrigger includes an outrigger box 1 and a horizontal outrigger 2. A plurality of bolt holes are formed on the outrigger box 1, and the positions of the bolt holes correspond to the hole positions on the rail grinding vehicle. The outrigger box 1 is detachably and fixedly connected to the rail grinding vehicle through bolts; the number of the horizontal outriggers 2 is two. The horizontal outriggers 2 are inserted into the outrigger box 1 and are slidably connected to the outrigger box 1, and the sliding direction of the horizontal outriggers 2 is horizontally arranged. The two horizontal outriggers 2 are respectively arranged on opposite sides of the outrigger box 1.
[0042] Referring to Figure 1 and Figure 2 , in order to facilitate the sliding of the horizontal outrigger 2, a telescopic oil cylinder 8 is bolted to the outrigger box 1. The piston rod of the telescopic oil cylinder 8 is connected to the horizontal outrigger 2, and the axial direction of the piston rod of the telescopic oil cylinder 8 is consistent with the sliding direction of the horizontal outrigger 2; in order to judge the lateral sliding distance of the horizontal outrigger 2 and thus judge the relative position relationship between the horizontal outrigger 2 and the rail, a cable length sensor is connected to the telescopic oil cylinder 8, and the cable length sensor is electrically connected to the central controller at the same time.
[0043] Referring to Figure 1 andFigure 2 Furthermore, the intelligent outrigger further includes vertical outriggers 3 and mounting seats 4. The number of both the vertical outriggers 3 and the mounting seats 4 is two. The vertical outriggers 3 are vertically arranged and have a fixed end and a movable end. The fixed end of the vertical outrigger 3 is bolted to the outer end of the horizontal outrigger 2. The telescopic function of the vertical outrigger 3 is realized by the driving of a support oil cylinder between the fixed end and the movable end of the vertical outrigger 3. Due to the vehicle gauge of the locomotives running on the railway, the support oil cylinder is selected in the form of a two-stage oil cylinder, and a hysteresis type telescopic length sensor is built in the support oil cylinder. The hysteresis type telescopic length sensor is electrically connected to the central controller; the mounting seat 4 is bolted to the movable end of the vertical outrigger 3.
[0044] Refer to Figure 2 and Figure 3 Furthermore, in order to provide a force application point for the vertical outrigger 3, the intelligent outrigger further includes swing oil cylinders 5 and outrigger discs 6. The number of both the swing oil cylinders 5 and the outrigger discs 6 is two. The swing oil cylinders 5 are fixed on the mounting seats 4, and the rotation axis of the swing oil cylinders 5 is horizontally arranged and perpendicular to the sliding direction of the horizontal outrigger 2. One end of the outrigger disc 6 is connected to the piston rod of the swing oil cylinder 5, and a transverse force-bearing beam 7 is welded and fixed on the outrigger disc 6.

The transverse force-bearing beam 7 passes through multiple bending-resistant reinforcing rib plates. The transverse force-bearing beam 7 and the bending-resistant reinforcing rib plates can be welded and fixed or can be slidably inserted to realize the quick replacement of the transverse force-bearing beam 7.
[0045] Refer to Figure 2 and Figure 3 Specifically, one end of the outrigger disc 6 away from the swing oil cylinder 5 is warped upward to form a clamping portion 61. The side of the clamping portion 61 facing the swing oil cylinder 5 can abut against the rail. Through the clamping portion 61, the connection stability between the outrigger disc 6 and the rail can be increased, and the possibility of the outrigger disc 6 being disengaged from the rail can be reduced; further, when the transverse force-bearing beam 7 abuts against the top wall of the sleeper, the lower edge of the movable end of the vertical outrigger 3 abuts against the outrigger disc 6, and then the force borne by the vertical outrigger 3 is applied to the outrigger disc 6; moreover, the flipping angle of the outrigger disc 6 is between 0 - 270 degrees. An insertion shaft type angle encoder is connected to the swing oil cylinder 5 to identify the inclination angle of the outrigger disc 6, and the insertion shaft type angle encoder is electrically connected to the central controller.
[0046] The implementation principle of an intelligent outrigger in an embodiment of this application is as follows: First, connect the outrigger box 1 to the rail grinding vehicle and keep the outrigger box 1 horizontal; then clean the ballast under the rail corresponding to the outrigger disc 6 to form a cavity; subsequently, drive the vertical outrigger 3 to move horizontally in place by the horizontal outrigger 2; then drive the outrigger disc 6 to turn outwards by a certain angle through the swing oil cylinder 5, and drive the mounting seat 4 to descend to a set position by the movable end of the vertical outrigger 3 to complete the preparatory actions before the outrigger disc 6 is obliquely inserted; while the movable end of the vertical outrigger 3 descends, drive the outrigger disc 6 to turn through the swing oil cylinder 5 until the end of the outrigger disc 6 away from the swing oil cylinder 5 passes through the cavity and the transverse force-bearing beam 7 abuts against the top wall of the sleeper.
[0047] At this time, lift the rail grinding vehicle until the lowest point of the wheel flange is not less than 1500 mm from the rail surface, move the road maintenance flat car under the rail grinding vehicle, and the mushroom head on the road maintenance flat car is in the position directly opposite to the mounting corner piece of the rail grinding vehicle. Lower the vertical outrigger 3 to make the rail grinding vehicle sit on the road maintenance flat car and then reset the outrigger disc 6 to its initial state; after transporting the rail grinding vehicle to the grinding section by the road maintenance flat car, lift the rail grinding vehicle to a set distance again and then separate the mushroom head on the road maintenance flat car from the mounting corner piece of the grinding vehicle, remove the road maintenance flat car, and then lower the fixed end of the vertical outrigger 3 and drive the rail grinding vehicle to descend through the outrigger box 1 until the rail grinding vehicle lands on the rail and then reset the outrigger disc 6 to its initial state.
[0048] The outrigger box 1 can be detachably and fixedly connected to the rail grinding vehicle. The horizontal movement of the vertical outrigger 3 can be realized through the horizontal outrigger 2, thereby adjusting the relative positions of the outrigger disc 6, the rail, and the sleeper.
