Description

Manual braking emergency water tracking and draining vehicle with double-end synchronous lifting submersible pump

Technical Field

The invention relates to the field of mine drainage equipment, in particular to a manual braking emergency water tracking and draining vehicle with double-end synchronous lifting submersible pumps.

Background

The current energy structure still takes coal as the main material, and the demand of the coal is still huge in the foreseeable future. As the depth of coal mining increases, the risk of mining increases, and among many coal mine safety accidents, water inrush accidents have become the second most productive 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 can not be completely eradicated, and once the water inrush accidents occur, the life safety of workers and the normal production of coal mines are seriously threatened. The higher the drainage efficiency in drainage rescue, the less life and property loss will be, so the emergency drainage work of the coal mine needs to be done.

At present, when the coal mine is subjected to emergency drainage rescue, a plurality of water pumps are required to work simultaneously so as to accelerate the drainage speed; moreover, the accumulated water contains more impurities, and the drainage pump is extremely easy to damage, so that a plurality of water pumps are needed to be prepared at a water pumping point for standby. The mine drainage rescue generally uses a large-flow and high-lift submersible pump, and is large in size and heavy in weight. However, when the transportation of the water pump is mostly manual transportation, the workload is very large, and especially in a roadway with limited width, the transportation efficiency is low, and the water pump is extremely easy to damage due to collision in the transportation process, so that the rescue difficulty is greatly increased.

Most of the existing submerged pump delivery vehicles are small-wheel flat vehicles with simple structures, and the whole structure is as follows: the small-diameter wheels are arranged below the frame and serve as a travelling mechanism, a flat plate for placing the water pump is welded on the frame, a clamp for fixing the water pump is arranged on the flat plate, and the water pump is lifted on the flat plate and fixed by the clamp when the bicycle is used. The small-wheel flat car has the following defects in use although the small-wheel flat car is simple in structure: firstly, the small-wheel flat car adopts the wheel that the diameter is less for the ability that the dolly spanned the obstacle is lower, and the second, small-wheel flat car chassis is lower, in abominable colliery ground environment, the performance is very poor, thirdly, need the manpower to lift when placing the water pump on the dolly, increase workman's intensity of labour, fourth, the water pump is placed on the dolly, through the clamp fixed, because dolly and water pump rigid connection, the vibration is very big in the dolly motion process, so cause the damage of pump easily, fifth, small-wheel flat car does not have arresting gear, only be suitable for mild tunnel, and a section of complete tunnel is by flat tunnel and inclined tunnel constitution more, so in fact can supply the tunnel of this normal operating of car less. In view of the above drawbacks, small-wheel flatcars do not comply with the transportation of water pumps in mining environments.

Therefore, the submerged pump water-tracking vehicle has the advantages of good passing performance in the complex ground environment of the coal mine, normal work in the inclined roadway, and necessary and urgent task of reducing the labor capacity of workers and avoiding the damage of the water pump in transportation.
