[0039] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific operation is as follows. A rest and support cabin for long-distance tunnel construction

[0040] First, the equipment can be disassembled and transported to the corresponding position in the tunnel project, and the first deck 11 with the universal wheel 13 is used as the bottom, and the other first deck 11 is used as the ceiling. The second deck 15 and the third deck 17 can be symmetrically arranged and fixed between the two first decks 11 by means of the adapter claws 12, and assembled to form a protective rest cabin;

[0041] The movement after assembly can be pushed by the universal wheel 13, or after controlling the reverse direction, the first hydraulic cylinder 181 and the second hydraulic cylinder 182 in the auxiliary assembly 18 can be driven to extend and retract by the battery, and the angle of the first hydraulic cylinder 181 can be adjusted by the second hydraulic cylinder 182. The top claw 183 on the first hydraulic cylinder 181 can be used to contact the ground to apply force, so as to push the device to move;

[0042] When in use, the rest cabin can be entered by opening the door body 16, and the rest cabin can be connected to the oxygen supply ventilation duct through the oxygen supply interface to supply air and oxygen; the user can directly sit or lie down to rest with the help of the battery box 14, and the lighting lamp 184 driven by the power supply of the battery box 14 will illuminate the rest cabin;

[0043] The clamp arm 21 not fixed on the third deck 17 can also be pulled to move the other clamp arm 21 in the lying structure 2 relatively away, and the connecting rod 22 can be flipped open, and then the bed board 23 can be lowered to a horizontal state, and the top column 25 can be contacted and limited with the clamp arm 21 to support the bed board 23, so that the person can lie on the bed board 23, and the electric heating wire 24 can also be driven to heat it to prevent the inside from being damp and cold;

[0044] When the bed board 23 is flipped open, the steel mesh screen 185 is exposed, which improves the ventilation effect, prevents the rest cabin from getting stuffy, and blocks mosquitoes. In the event of an accident, the fastening bolts 186 can be removed to remove the steel mesh screen 185 from the inside for escape.

[0045] When the bed board 23 is set horizontally, it can also serve as a dining table for placing meals; pulling the stool board 31 in the sitting structure 3 causes the first arm 32 and the second arm 35 therebetween to flip open, and as the second arm 35 flips, one end of the second arm 35 squeezes the locking rod 33 and compresses the spring 34. When the first arm 32 and the second arm 35 are horizontally docked, the locking hole on the second arm 35 will be fitted on the locking rod 33, and the locking rod 33 will be stably locked by the action of the spring 34, so that the first arm 32 and the second arm 35 cannot flip relative to each other, and can be used to support between the stool boards 31 to form a foldable stool.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
