Abstract
The utility model provides a mining flame-proof type vacuum feed switch, includes flame proof casing, vacuum circuit breaker, handle, connecting axle, gear, rack, actuating lever, seat cover, set up two vacuum circuit breakers in the flame proof casing at least, each vacuum circuit breaker is provided with circuit breaker switch, the handle passes through the gear connection in connecting axle and the flame proof casing, the actuating lever upper end is the rack, rack and gear intermeshing, during the actuating lever lower extreme inserted the seat cover, be provided with the contact with circuit breaker switch one-to-one on the actuating lever. The utility model has an independent manual brake separating mechanism, and can cut off the feed switch of the current stage without cutting off the power supply of the upper stage, thereby greatly improving the safety; flexible operation and difficult clamping stagnation.
Description
Technical Field
The utility model belongs to the technical field of mining electromechanical device, concretely relates to mining flame-proof type vacuum feed switch.
Background
The mining flame-proof type vacuum feed switch is commonly used in the environment of methane, coal dust and explosive gas under a coal mine, and generally comprises a flame-proof shell, a vacuum circuit breaker, an isolating switch, a control unit, a display unit and the like which are positioned in the flame-proof shell.
Therefore, the existing mining explosion-proof vacuum feed switch needs to be improved, and a manual opening mechanism is arranged on the existing mining explosion-proof vacuum feed switch, so that each loop of the feed switch has an independent manual opening function.
SUMMERY OF THE UTILITY MODEL
The utility model provides a mining flame-proof type vacuum feed switch sets up manual separating brake mechanism to it to make each return circuit of feed switch have independent manual separating brake function.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a mining flame-proof type vacuum feed switch, includes flame proof casing, vacuum circuit breaker, handle, connecting axle, gear, rack, actuating lever, seat cover, set up two vacuum circuit breakers in the flame proof casing at least, each vacuum circuit breaker is provided with circuit breaker switch, the handle passes through the gear connection in connecting axle and the flame proof casing, the actuating lever upper end is the rack, rack and gear intermeshing, during the actuating lever lower extreme inserted the seat cover, be provided with the contact with circuit breaker switch one-to-one on the actuating lever.
And a return spring is fixed in the seat sleeve.
And a pressure plate is arranged at the top of the return spring.
The utility model has the advantages that: the utility model discloses but the mechanism of independent separating brake has been set up to different vacuum circuit breakers, through rack and pinion drive actuating lever, when needs promptly to cut off power, need not to cut off higher level's power and can cut off this level of feed switch, the security improves greatly; meanwhile, the operation is flexible, and clamping stagnation is not easy to occur.
