[0037] It should be noted that the present invention is a continuous stepping mining equipment train.
[0038] 1. In the initial state, there is a height difference between the inner walking guide rail 8 and the outer walking guide rail 10, the inner walking guide rail 8 is suspended in the air, and the outer walking guide rail 10 is on the ground. Figure 2 and attached Figure 3 ;
[0039] 2. First state: the inner walking guide rail 8 moves horizontally:
[0040] The hydraulic cylinder of the second power device 13 extends its telescopic rod, and the upper end of the second power device 13 is fixed to the bottom of the vehicle body 11, the outer running guide rail 10 touches the ground, and the first power device 12 pulls the inner running guide rail 8, so the vehicle body 11 moves together with the inner running guide rail 8; Figure 4and attached Figure 5 ;
[0041] 3. Second state: the outer running guide rail 10 is lifted, the vehicle body is lowered, and the inner running guide rail 8 is in contact with the ground;
[0042] The third power device 14 is configured as a hydraulic cylinder, which pushes the second roller group bracket 6 to rotate around the U-shaped bracket 4. The second roller group bracket 6 pulls the L-shaped lifting arm 1 to lift. The L-shaped lifting arm 1 engages with the outer walking guide rail 10 to lift the outer walking guide rail 10, thereby replacing the outer walking guide rail 10 and the inner walking guide rail 8 in contact with the ground. The outer walking guide rail 10 is lifted, the inner walking guide rail 8 is in contact with the ground, and the vehicle body descends. Figure 6 and attached Figure 7 ;
[0043] 4. The third state: the hydraulic cylinder of the second power device 13 connected to the outer walking rail 10 is retracted, and the hydraulic cylinder of the first power device 12 connected to the inner walking rail 8 is extended. Due to the friction between the inner walking rail 8 and the ground, the vehicle body 11 moves on the inner walking rail 8 by relying on the first roller group bracket 3 and the rollers; as shown in the attached Figure 8 and attached Fig. 9 ;
[0044] 5. Return to the initial state: the outer walking guide rail 10 is lowered, the outer walking guide rail 10 is in contact with the ground, the vehicle body is lifted, and the inner walking guide rail 8 is suspended;
[0045] The third power device 14 is configured as a hydraulic cylinder, which pulls the second roller bracket 6 to rotate around the U-shaped bracket 4. The second roller bracket 6 pulls the L-shaped lifting arm 1 to descend. The L-shaped lifting arm 1 engages with the outer walking guide rail 10 to lower the outer walking guide rail 10, thereby realizing the replacement of the outer walking guide rail 10 and the inner walking guide rail 8 in contact with the ground, and the inner walking guide rail 8 is lifted.
[0046] At this time, due to the height difference between the inner walking guide rail 8 and the outer walking guide rail 10, the inner walking guide rail 8 is higher than the outer walking guide rail 10, and the natural state is restored, that is, the inner walking guide rail 8 is suspended in the air, and the outer walking guide rail 10 is in contact with the ground, and the vehicle body is lifted and restored to the initial state, forming a cycle, as shown in the attached figure. Figure 2 and attached Figure 3 .
