A manual braking emergency drainage vehicle with double-end synchronously
lifting submersible pump
The utility model relates to the field of mine drainage equipment, in particular to a
manual braking emergency drainage vehicle with double-end synchronously lifting
submersible pumps.
At present, the energy structure is still dominated by coal, and the demand for coal is still
huge in the foreseeable future. With the increase of coal mining depth, the risk of mining
is increasing. Among many coal mine safety accidents, water inrush accident has become
the second largest production safety accident after gas explosion, although various
technologies have been adopted in coal mine production to prevent water inrush
accidents, but the accidents still cannot be completely avoided. Once water inrush
accidents occur, workers' life safety and normal production of coal mines will face
serious threats. In drainage rescue, the higher the drainage efficiency, the less the loss of
life and property, so it is necessary to improve the technology of emergency drainage in
coal mines.
At present, in emergency drainage and rescue of coal mine, multiple pumps need to work
at the same time to speed up drainage. Moreover, the accumulated water contains more
impurities, and the drainage pump is easily damaged, so it is necessary to prepare
multiple pumps at the pumping points for standby. Mine drainage rescue generally uses
submersible pumps with large flow and high lift, which are large and heavy. However, at
present, most of the pumps are transported by manpower, and the workload is very heavy.
Especially in the roadway with limited width, the transportation efficiency is low, and the
pumps are easily damaged by collision during transportation, which greatly increases the
difficulty of rescue.
The existing submersible pump consignment trucks are mostly small-wheel flat-bed
trucks with simple structure, and the overall structure is as follows: small-diameter
wheels are installed under the frame as a traveling mechanism, a flat plate for placing a
water pump is welded on the frame, and a clamp for fixing the water pump is arranged on
the flat plate when in use. Although the structure of small wheel flat car is simple, it has
the following shortcomings in use: first, the small-wheel flatbed car adopts wheels with
smaller diameters, which makes the car have lower ability to cross obstacles. Secondly,
the chassis of the small-wheel flat car is low, and the passing performance is very poor in
the harsh coal mine ground environment. Thirdly, when the water pump is placed on the
trolley, it needs to be lifted manually, which increases the labor intensity of workers.
Fourthly, the water pump is placed on the trolley and fixed by clamps. Because the trolley
is rigidly connected with the water pump, the trolley vibrates greatly during its
movement, so it is easy to cause damage to the pump. Fifthly, the small wheel flat car has
no braking device, and is only suitable for gentle roadways, while a complete roadway is
mostly composed of flat roadways and inclined roadways, so there are few roadways
available for the normal operation of the car in practice. In view of the above
shortcomings, the small wheel flat car is not suitable for the transportation of water pump
in mining environment.
Therefore, it is necessary and urgent to develop a submersible pump drainage vehicle
with good passing performance in complex ground environment of coal mine, which can work normally in gently inclined roadway, reduce workers' labor and avoid water pump damage during transportation.
The purpose of this utility model is to provide a manual braking emergency drainage
vehicle with double-end synchronously lifting submersible pump, in order to solve the
above problems, and to provide a drainage vehicle which has good passability in complex
ground environment of coal mine, can be used in gently inclined roadway, can reduce
