[0021] The working cabin 1 has a working window assembly on the front, which includes upper movable baffles 131, a working window 132, lower movable baffles 133 and a driving motor 5. The upper movable baffles 131 are arranged in parallel vertically in front of the working window 132 and slide with each other. The top of the front plate of the upper movable baffles 131 has a horizontal protrusion 134, and the bottom of the back plate is provided with the same horizontal protrusion 134. Two adjacent upper movable baffles 131 are placed in parallel and closely. The bottom protrusion of the first upper movable baffle 131 clamps the top protrusion of the second upper movable baffle 131. During the movement of the upper movable baffles 131, the two protrusions are used for limiting. The top and bottom of the front plate of the working window 132 are each provided with a horizontal protrusion 134, and a rectangular opening is fixed in the working window 132. The top protrusion of the working window 132 is hung on the bottom protrusion of the adjacent upper movable baffle 131.

When the upper movable baffle 131 rises or falls, the third upper movable baffle 131 rises or falls, and the third upper movable baffle 131 acts as a movable pulley to drive the fourth upper movable baffle 131 to rise or fall. In this way, the last working window is driven to rise or fall. The back of the working cabin 1 is provided with airtight cabin doors for personnel and material access.The lifting and lowering of the upper movable baffle 131 is not limited to the use of the driving motor 5 alone, but can also be other linear motion control mechanisms such as hydraulic cylinders and lead screws.

[0022] The four corners of the working cabin 1 bottom are provided with four power wheel groups 11, each of which comprises a support rod 111, a steering motor 112, a power motor 113 and a power wheel 114, one end of the support rod 111 is connected to the working cabin 1, the other end is connected to the steering motor 112, the power wheel 114 is connected below the steering motor 112, the steering motor 112 can move the entire device or the working cabin 1 in any direction and at any angle, greatly enhancing the passability in a narrow space, and the power motor 113 is fixed on the side surface of the power wheel 114 shaft.

[0023] The support assembly comprises a base 21, an arch assembly 22, a second telescopic rod 23, a mounting plate 24, a side panel 25 and a fifth telescopic rod 26, one end of the second telescopic rod 23 is connected to the base 21, the other end is connected to the mounting plate 24, the bottom surface of the mounting plate 24 is horizontal, and the top surface has an angle with the bottom surface, so that when there are small falling rocks on the top of the roadway, they can roll down along the slope of the top surface, reducing the load on the top surface, the top surface of the mounting plate 24 is connected to the side panel 25 on both sides through hinges, and the fifth telescopic rod 26 is hingedly connected to the middle of the side panel 25 at one end and to the mounting seat on the bottom surface of the mounting plate 24 at the other end, wherein the angle of the mounting seat is perpendicular to the top surface of the mounting plate 24, and the two side panels 25 are unfolded to increase the support space on the top, and when not unfolded, they are folded on both sides to reduce the occupied space and increase the passability, or when working on one side, the single side panel 25 is folded, the working cabin 1 works on one side, and the arch assembly 22 is arranged on the top surface of the mounting plate 24 and on the side panel 25.

[0024] The arch assembly 22 comprises a pressure sensor 221, a third telescopic rod 222, a connecting cross rod 223, a support roof 224 and a fourth telescopic rod 225, one end of the third telescopic rod 222 is hingedly connected to the mounting seat of the installation surface, the other end is connected to the support roof 224 through a ball head, the connection mode of the third telescopic rod 222 and the support roof 224 adopts the form of a ball head and a ball head seat, which can make the support roof 224 self-adapt to the arc shape of the top surface and cope with complex conditions of the uneven top surface, thereby increasing the reliability of the support, the third telescopic rods 222 are arranged transversely in several rows, each row of third telescopic rods 222 is provided with a connecting cross rod 223 in the middle to be connected to each other, and each row of first third telescopic rods 222 is provided with a fourth telescopic rod 225 in the middle to control the third telescopic rod 222 to stand vertically, when in a non-working state, the fourth telescopic rod 225 is retracted, and all third telescopic rods 222 and support roofs 224 are folded up to reduce the occupied space, and the other end of the fourth telescopic rod 225 is hingedly connected to a small mounting seat on the installation surface of the arch assembly 22.

[0025] The pressure sensor 221 is installed on the third telescopic rod 222 to detect the real-time pressure state of the third telescopic rod 222, and when the pressure sensor 221 exceeds a threshold value, it means that there is a large rockfall or a collapse danger at a certain place, and the working cabin 1 starts to escape. The pressure sensor 221 is a TURCK pressure sensor, and when the pressure it bears is greater than the set threshold value, the internal buzzer will alarm.

[0026] Working principle: when entering the roadway, the first telescopic rod 3, the second telescopic rod 23, the fifth telescopic rod 26, the third telescopic rod 222 and the fourth telescopic rod 225 are retracted, and the power wheel set 11 at the bottom of the working cabin 1 carries the entire device into the working face, and then the second telescopic rod 23, the fifth telescopic rod 26, the third telescopic rod 222 and the fourth telescopic rod 225 are elongated to support the inner wall of the roadway, and then the four first telescopic rods 3 are elongated and work cooperatively to control the working cabin 1 in its working position. The electromagnetic head 4 is always in an energized state during this process, and the moving working window 132 finds the specific working point. When the pressure sensor 221 exceeds the threshold value, the four first telescopic rods 3 quickly retract to drop the working cabin 1 back to the ground, the electromagnetic head 4 is de-energized, and the first telescopic rod 3 continues to retract to separate the working cabin 1 from the support assembly, and the power wheel set 11 carries the working cabin 1 to quickly escape from the roadway to complete the escape. When personnel work in the working cabin 1, the driving motor 5 pulls the upper moving baffle 131 up, which drives the working window 132 to rise, and at the same time, the working window 132 drives the lower moving baffle 133 to rise, so that the position of the working window 132 changes while other positions are protected at all times, reducing the danger and loss during charging operation. When personnel need to work in the corner on the side, the side panel 25 is folded down to support the side wall rock, improving the support strength and effect.

Therefore, if a person skilled in the art is inspired thereby, without departing from the purpose of the present application, similar structural modes and embodiments can be designed without creativity, which should all belong to the protection scope of the present application.
