Can understand that by above given technical scheme the utility model is pulled by handle downwards under the normal power supply situation, make carrier gear throw off with pinion and gear wheel respectively, by the unlatching of motor-driven shield door or close.Under the emergency rating that has a power failure, handle upwards can be pulled, make carrier gear mesh with pinion and gear wheel respectively; Manually rotate handwheel then,, pass through carrier gear by gear wheel by second bevel gear reverse and second bevel gear reverse, drive motors tail end pinion, pass through the shield door drive system again, and make shield door open or close, thereby realize the purpose that the utility model will be realized.The bevel gear reverse that the utility model is included also can adopt such as other commutators such as worm and gears.
The utility model also comprises the power supply signal switch; Described power supply signal switch be installed in the carrier gear closing device near.Because the existence of power supply signal switch can realize right judgement to on-the-spot power supply situation.
The utility model also advocates, also comprises and the spout handle keeper of one each other; Described handle keeper is provided with the vertical chute and the horizontal concrete chute that can hold handle; Under working condition, described handle can enter horizontal concrete chute by vertical chute, and makes carrier gear keep engagement with pinion and gear wheel respectively.In the condition that does not have described handle positioning component, can take other technical measures such as fastening handle with rope, do not allow it move up and down.This also is fine certainly.
The utility model advocates that also described support arm is provided with slotted hole along its length; The minor axis of described carrier gear is located in the slotted hole of support arm; The adjustment of minor axis and support arm relative position by carrier gear makes carrier gear keep the normal engaged state with pinion and gear wheel respectively.Because support arm is provided with slotted hole, can complies with one's wishes and adjust the engagement of carrier gear and pinion and gear wheel, and make this engagement keep normal.
After technique scheme was implemented, what the utility model had was rational in infrastructure, used lightly, and the shield door switch is laborsaving etc., and characteristics are conspicuous.
Should be noted that the utility model is specially adapted to tall and big heavy shield door and uses.When under the less condition of shield door, can be located at second bevel gear reverse of low level, and directly with handwheel and coaxial connection of power input bevel gear that is located at the first high-order bevel gear reverse.This shows why the utility model establishes two bevel gear reverses, its purpose mainly is to be convenient to personnel operation.Can certainly alleviate hand-driven strength.
