As the depth of coal mining increases, the risk of mining is also increasing, and among many coal mine safety accidents, the water inrush accident has become the second largest production safety accident next to gas explosion. Although various technologies have been adopted in coal mine production to prevent water inrush accidents, the water inrush accidents are still not completely eradicated, and once the water inrush accidents occur, the life safety of workers and the normal production of the coal mine face serious threats. The higher the drainage efficiency in drainage rescue, the less the life and property loss will be, so the coal mine emergency drainage work needs to be done.
At present, a plurality of water pumps are required to work simultaneously during emergency drainage rescue of a coal mine so as to accelerate the drainage speed; in addition, the accumulated water contains more impurities, and the drainage pump is easy to damage, so a plurality of water pumps are needed to be prepared for standby at a water pumping point. The mine drainage rescue generally uses a large-flow and high-lift submersible pump, and has large volume and heavy weight. However, most of the water pumps are transported manually, the workload is very large, especially in a roadway with limited width, the transportation efficiency is low, and the water pumps are easily damaged due to collision in the transporting process, so that the rescue difficulty is greatly increased.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The first embodiment is as follows:
referring to fig. 1-7, the embodiment provides a manual braking emergency catch-up drainage vehicle for double-end synchronous hoisting of a submersible pump, which includes a portal-shaped traveling frame 5, a manual synchronous hoisting device 2 fixedly connected to the top of the portal-shaped traveling frame 5, a large-diameter wheel-type traveling mechanism 1 rotatably connected to the bottom of the portal-shaped traveling frame 5, and a drainage system 3 detachably connected below the manual synchronous hoisting device 2, wherein a manual braking device 4 is arranged outside the large-diameter wheel-type traveling mechanism 1;
the portal type traveling frame 5 comprises at least two bottom longitudinal beams 5-1 which are arranged in parallel, the top of each bottom longitudinal beam 5-1 is vertically and fixedly connected with at least two supporting columns 5-2, the tops of the supporting columns 5-2 are fixedly connected with top longitudinal beams 5-3, and a plurality of top cross beams 5-4 are fixedly connected between the top longitudinal beams 5-3;
the manual synchronous lifting device 2 comprises a load lifting hook 2-5, the top of the load lifting hook 2-5 is connected with a lifting driving part, and the lifting driving part is fixedly connected to the top of a top cross beam 5-4;
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.
The lifting driving part adopts a mode of combining two worm and gear lifting mechanisms, and the worms 2-2 of the two lifting mechanisms are connected through a pair of universal couplings 2-3, so that the effect that only one end of power is input, and the two lifting mechanisms synchronously lift at the same time and the two ends is achieved. The power source of the device adopts a manual mode, and power is transmitted to the worm 2-2 through the hand-operated wheel 2-1. The device has the advantages of compact structure, small volume, light weight, convenient installation, flexible use, high reliability, long service life and the like, and is suitable for being used in industrial and mining environments.
According to the further optimized scheme, two opposite side walls of the elevator box body 2-8 are fixedly connected with anti-rotation end covers 2-9, end cover lugs 2-9a are arranged on the inner side walls of through holes of the anti-rotation end covers 2-9, screw rod key grooves 2-4a are formed in the side walls of the lifting screw rods 2-4, and the end cover lugs 2-9a and the screw rod key grooves 2-4a are matched and slide.
Under the condition of no load of the manual synchronous hoisting device 2, the phenomenon that the lifting screw rods 2-4 cannot be lifted normally due to synchronous rotation of the worm gears 2-7 can occur, and in order to eliminate the rotation phenomenon, the invention is particularly designed to prevent rotation. The lifting screw rod 2-4 is provided with a screw rod key groove 2-4a which is axially through, an end cover lug 2-9a is designed on the hole edge of an anti-rotation end cover 2-9 of the lifting box body 2-8, and the structure and the function of the end cover lug 2-9a are similar to those of a flat key.
