Abstract
The utility model discloses a manual operation device of an electric actuator. The manual operation device is characterized in that a rotatable sliding cover small shaft is mounted in a box body; a safety sliding cover is fixed at the outer end of the sliding cover small shaft and a cam is fixed at the inner end of the sliding cover small shaft; a microswitch cuts off a motor power supply when being touched by the cam; a motor is mounted in the box body and on a reduction gearbox; a driving gear is mounted on the output shaft of the reduction gearbox; a rotary intermediate gear is meshed with the driving gear and is fixed on a worm shaft; an inner sexangular hole is formed on the outer side of the worm shaft; and a worm is meshed with a worm wheel, the worm wheel is fixed on a shaft gear, and the shaft gear is used for driving a master gear to run, and the master gear is fixed on a spindle connected with a valve rod of a valve through a coupling. The running motor drives the gear, and the intermediate gear, the worm, the worm wheel, the shaft gear, the master gear and the spindle run simultaneously to switch the valve; the manual operation is needed to switch the valve in case of power failure, the safety sliding cover is moved by hand and a sexangular handle is inserted into the inner sexangular hole of a worm shaft to rotate, so as to open the valve; when the safety sliding cover is moved, the cam touches the microswitch to cut off the motor power supply; and the motor cannot run when the power supply is recovered during manual operation, so as to ensure safe valve operation.
Description
Technical field:
The utility model belongs to the electric actuator field, specifically belongs to rotary type electric actuator hand-operating device.
Background technology:
Existing electric actuator, it exists shortcoming as follows: 1, worm screw is also rotated simultaneously during motor rotation, therefore reply the electrical convertors and generators worm shaft that turns round in hand rotary worm axle suddenly and be rotated under situation about having a power failure, operating personnel are sustained damage by driven by motor; 2, cause damage, worm shaft to be provided with clutch for fear of in the middle of manual operation, replying electricity suddenly, though this electric actuator can realize the safety operation purpose, a lot of costs of the complicated increase of clutch configuration.
The utility model content:
The purpose of this utility model is to provide hand-operating device, safety, reliable, cost is low.Overcome the shortcoming and defect that existing electric actuator exists.
To achieve these goals, technical solutions of the utility model are: a kind of electric actuator hand-operating device, comprise casing, be installed in casing and the little axle of rotatable slip lid, at the fixing safe slip lid in the little axle of slip lid outer end, the slip lid fixed screw, at the inner stationary cam of the little axle of slip lid, cut off the sensitive switch of motor power when being touched by cam, bearing cap, the bolt of rigid bearing lid, be installed in the bearing of worm shaft, the switch fixed head, the switch fixed head is fixed on the screw of casing, be installed in the spring between cam and the switch fixed head, but the motor of rotating, the reduction box that is connected with motor, be installed in the driven wheel of reduction gearbox output shaft, the idler gear of driven wheel engagement, the worm screw of idler gear is installed, worm gear with worm engaging, be embedded in the shaft gear of worm gear, master gear with the shaft gear engagement, be embedded in the output shaft of master gear.Safe slip lid is that the center can rotate with the little axle of slip lid, and when moving safe slip lid with hand, the cam on the little axle of slip lid touches sensitive switch cuts off motor power, and whether no matter there are electrical convertors and generators not turn round, so worm shaft can not rotate yet.Aperture when moving safe slip lid with hand on the slip lid is concentric with the worm shaft inner hexagonal hole, can insert worm shaft and rotation to the hexagonal handle, can the hand switch valve.Mounting spring between cam and the casing, this safe slip lid is rotated by spring when decontroling safe slip lid, cam leaves electric wire that sensitive switch leads to motor and connects motor and can turn round, and safe slip lid is rotated the back slip lid and covers worm shaft simultaneously, and the hexagonal screwdriver can't insert worm shaft and guarantee safety.The little axle of slip lid is gone up the processing groove O type circle of packing into, makes box house and external isolation guarantee to seal.
Operation principle: to the electric actuator energising, driven wheel, idler gear, worm screw, worm gear, shaft gear, master gear, output shaft rotate synchronously when motor rotation.Output shaft drives rotations such as valve, air door.When needing the hand switch valve under the situation about having a power failure, move safe slip lid with hand the cam that is fixed on the little axle of slip lid is rotated simultaneously, sensitive switch cuts off towards the electric wire motor of motor and can not rotate when cam touches sensitive switch.Hole when safe slip lid forwards certain position on the slip lid is concentric with worm shaft, and instruments such as hexagonal handle or screwdriver insert the worm shaft inner hexagonal hole, and turning handle can controlled valve.Extract from worm shaft when handle that cam is transferred to initial position under the spring action that is installed between cam and the switch fixed head, slip lid covered the worm shaft inner hexagonal hole when sensitive switch was switched on, and guaranteed safe manual operation.
