[0027] In order to cope with narrow tunnels, mining equipment will be equipped with a retractable walking chassis, the width of which is shorter than that of a general walking chassis after retracting, and the width of a conventional support device is not applicable. In this support device, the first drive member 6 is set below the second support frame 5, so that the first drive member 6 does not occupy the width space in the retracted state, and the overall width of the second support frame 5 is shorter after folding, which is suitable for narrow tunnels and can be used in conjunction with mining equipment equipped with a retractable walking chassis.

[0028] In order to improve the supporting effect, a third supporting frame 7 is provided on the end of the second supporting frame 5 away from the first supporting frame 4, and the third supporting frame 7 is rotatably connected to the second supporting frame 5; when the third supporting frame 7 and the second supporting frame 5 are both retracted, the third supporting frame 7 is located directly above or directly below the second supporting frame 5. In this embodiment, the third supporting frame 7 is arranged directly above the second supporting frame 5 to facilitate avoiding the first driving member 6. The design of the third supporting frame 7 can expand the supporting area, and the third supporting frame 7 can be rotated, so that it can be deployed and used during work, and can be rotated and retracted after work to reduce the occupation of space and facilitate passing through narrow alleys; when the third supporting frame 7 is retracted, the third supporting frame 7 is arranged directly above or directly below the second supporting frame 5, so that the third supporting frame 7 will not exceed the second supporting frame 5, which is convenient for controlling the width of the retracted state.

[0029] In order to improve the supporting effect, a fourth support frame 8 is provided on the end of the second support frame 5 away from the first support frame 4, and the fourth support frame 8 is rotatably connected to the second support frame 5; when the third support frame 7 and the second support frame 5 are both retracted, the fourth support frame 8 is located inside the third support frame 7. The design of the fourth support frame 8 can expand the supporting area, and the fourth support frame 8 can be rotated, so that it can be deployed and used during work, and can be rotated and retracted after work to reduce the occupation of space and facilitate passing through narrow lanes; the fourth support frame 8 is arranged on the inside, and will not exceed the second support frame 5 in the retracted state, so as to control the width of the retracted state.

[0030] In order to ensure the reliable installation of the third support frame 7, Figure 5As shown, a limiting seat 9 is provided on the second supporting frame 5, and the limiting seat 9 is arranged directly above the second supporting frame 5. The limiting seat 9 is fixedly connected to the second supporting frame 5, and a U-shaped groove 10 is provided on the limiting seat 9. The opening of the U-shaped groove 10 faces the center of the second supporting frame 5.
