the drainage system 3 is detachably connected with the load lifting hooks 2-5 through flexible fiber ropes 2-6, and the drainage system 3 is located between the support columns 5-2.
The drainage system 3 is hoisted by the manual synchronous hoisting device 2, the labor intensity of manual operation is reduced, and the manual brake device 4 arranged on the outer side of the large-diameter wheel type travelling mechanism 1 can adapt to the use of an inclined roadway.
Further optimizing the scheme, the hoisting driving part comprises at least two elevator boxes 2-8 fixedly connected to the top of the door-shaped walking frame 5, worm wheels 2-7 are rotatably connected inside the elevator boxes 2-8, worms 2-2 are matched on the outer sides of the worm wheels 2-7, two ends of the worms 2-2 are rotatably connected with the elevator boxes 2-8, lifting screw rods 2-4 are connected with the centers of the worm wheels 2-7 in a threaded manner, the lifting screw rods 2-4 are vertically arranged, the lower ends of the lifting screw rods 2-4 are rotatably connected with the top of a load lifting hook 2-5, the worms 2-2 are parallel to the length direction of the door-shaped walking frame 5, namely a top longitudinal beam 5-3, and universal couplings 2-3 are rotatably connected at one ends of the two worms 2, one end of one worm 2-2 far away from the universal coupling 2-3 is fixedly connected with a hand-operated wheel 2-1.
