Then, the two bolt removing wrenches 32 are driven to move downwards by the second lifting mechanism 31 until the sleeve of the bolt removing wrenches 32 is sleeved outside the bolts. Finally, the bolt removing wrench 32 is started to remove the bolt. During the disassembly, the second lifting mechanism 31 is also correspondingly moved upwards.
Further, the track moving vehicle 1 comprises a vehicle body 10, an electric track wheel 11 and a supporting wheel 12, wherein the electric track wheel 11 is arranged on the vehicle body 10, the supporting wheel 12 is connected with the vehicle body 10 through a connecting shaft 13, one end of the connecting shaft 13 is fixedly connected with the vehicle body 10, and the other end of the connecting shaft 13 is rotatably connected with the supporting wheel 12.
In use, the electric rail wheel 11 is positioned on one side of the rail and the support wheel 12 is positioned on the other side of the rail. During the track jacking process, the vehicle body 10 is jacked up along with the track, while the diameter of the supporting wheel 12 is unchanged, so that the vehicle body 10 is inclined towards the track on the other side. Therefore, the following structure is also provided:
The movable rail car further comprises a conical supporting wheel 14 and a thrust mechanism 15, wherein the conical supporting wheel 14 is in sliding connection with the connecting shaft 13, one end of the conical supporting wheel 14 is spliced with the supporting wheel 12, the thrust mechanism 15 comprises a thrust shaft 150 and a tension spring 151, one end of the thrust shaft 150 is rotationally connected with the conical supporting wheel 14, and the other end of the thrust shaft 150 is connected with the car body 10 through a connecting rod mechanism 152. Both ends of the tension spring 151 are connected to the push shaft 150 and the vehicle body 10, respectively.
Specifically, a tension spring 151 is sleeved outside the connecting shaft 13, and two ends of the spring are fixedly connected with the pushing shaft 150 and the vehicle body 10 respectively. The link mechanism 152 is composed of two links hinged in sequence, the ends of which are hinged to the push shaft 150 and the vehicle body 10, respectively. The large diameter end of the tapered support wheel 14 is adjacent to the vehicle body 10, and the small and large diameter ends are adjacent to the track on the other side.
When the vehicle body 10 is lifted up along with one side rail, the tapered support wheels 14 are pushed to move towards the other side rail by the pushing mechanism 15, and the contact diameter between the tapered support wheels 14 and the other side rail can be changed (gradually increased) along with the movement of the tapered support wheels 14. That is, when the vehicle body 10 is lifted up along with the rail, the tapered support wheels 14 move to lift up the other end of the connecting shaft correspondingly, thereby preventing the vehicle body 10 from tilting toward the rail on the other side.
Further, the mounting plate 5 is hinged on the vehicle body 10, the spring support rod 6 is arranged between the mounting plate 5 and the vehicle body 10, the spring support rod 6 is of a structure in the prior art, and in the initial state, the mounting plate 5 and the vehicle body 10 are in a parallel state, and the spring support rod 6 is not compressed.
After the rail lifting assembly 2 is arranged on the mounting plate 5, namely when the rail lifting cylinder 22 is in contact with the ground and the rail is jacked up, the angle between the mounting plate 5 and the vehicle body 10 is changed, so that the spring support rod 6 is compressed to generate elastic potential energy. Meanwhile, a push plate 7 matched with the link mechanism 152 is fixed on the mounting plate 5, and when the angle between the mounting plate 5 and the vehicle body 10 changes, the push plate 7 pushes the link mechanism to move inwards, and due to the structural arrangement of the link mechanism 152, the push shaft 150 and the conical supporting wheel 14 are driven to move towards the other side rail.
Therefore, the above structure can realize linkage between the two, namely, after the track on one side of the vehicle body 10 is lifted (the height is changed), the conical supporting wheel 14 moves towards the track on the other side, so that the other end of the connecting shaft is correspondingly lifted, and the vehicle body 10 is prevented from tilting towards the track on the other side.
Further, a compressing assembly 8 is fixedly connected to the fixing frame 211, the compressing assembly 8 comprises a compressing shaft 80, a compressing spring 81 and a compressing plate 82, the compressing shaft 80 is slidably connected with the fixing frame 211, two ends of the compressing spring 81 are fixedly connected with the compressing shaft 80 and the fixing frame 211 respectively, and the compressing plate 82 is fixedly connected with the lower end of the compressing shaft 80.
When the first horizontal moving mechanism 21 and the rail lifting cylinder 22 are driven to move downwards by the first lifting mechanism 20, the pressing plate 82 gradually contacts with the rail, the pressing spring 81 is compressed, so that pressure can be applied to the rail, friction force is increased, and the displacement of the vehicle body 10 relative to the rail in the process of lifting the rail again is avoided.
The above description is given of only the preferred embodiment of the present invention, but the present invention is not limited to the above-described embodiment.
