Description

A kind of both hands wheel YE

Technical field

The utility model belongs to electric operator technical field, in particular to a kind of both hands wheel YE.

Background technology

Actuator is a kind of conventional electromechanical integration equipment of automation field, is three big composition portions of instrument and meter for automation Divide the execution equipment in (testing equipment, adjustment equipment and execution equipment).Mainly some equipment and device are grasped automatically Make, replace manual work to control its switch and adjust.By power type can be divided into pneumatic, surge, electronic, electro-hydraulic several classes such as dynamic. YE has the advantages that to take that the energy is convenient easily, transmission signal speed is fast, long distance of signal transmission, and it is accurate Degree, sensitivity are of a relatively high, and wiring convenient, easy to operate with the cooperation of other motorized adjustment instrument is installed simple, due to electricity being The actuator of power has the incomparable advantage of other a few class media, and therefore power type is with fastest developing speed in recent years, and application surface is wider.

Present electric performance device typically has electronic and manual two kinds of executive modes, occurs in electronic implementation procedure When power-off or other faults, realized manually operated by electric and hand switching mechanism.The primary structure of this kind of YE Including housing, it is vertically arranged with output shaft in housing, sheathed worm gear in the middle part of output shaft, it is provided with above output shaft and can control The handwheel of output shaft processed, when needing to carry out Non-follow control, carries out manual and electric conversion by adjusting joystick, in housing It is additionally provided with the worm screw with worm gear and by motor control of horizontal positioned.But existing YE is manually operated More laborious, not easy to operate, control efficiency is not high.

Utility model content

The utility model provides a kind of laborsaving, structure easy and simple to handle simple for solving technical problem present in known technology Single rational both hands wheel YE, this actuator easy accessibility, it is easy to regular maintenance, floor space is little, high working efficiency.

The utility model is adopted the technical scheme that by solving technical problem present in known technology: a kind of both hands wheel YE, including housing, is vertically arranged with output shaft in housing, is arranged with worm gear, in output shaft in the middle part of output shaft Top is provided with the first handwheel, also includes controlling the handle of electric and hand conversion, also includes horizontally disposed and worm wheel Worm screw, described worm screw one end and motor connection, the described worm screw other end pass through housing, also include the second handwheel, in second-hand It is connected with the adapter sleeve for being connected with worm screw, described adapter sleeve is the four directions passing through for worm screw at the installing hole of wheel inner side Inner hole structure；Also include the closure that is detachably arranged at installing hole outside the second handwheel and be arranged on worm screw exposed junction , dismountable dust cap.

Advantage of the present utility model and good effect are: this uses new employing both hands wheel construction, and wherein side handwheel is removable Unload, the utility model adopts two ways to control output shaft, in addition to traditional top handwheel directly controls output shaft, also sets Having put side handwheel drives worm screw to control output shaft, makes torsion save half when moment is larger using side handwheel, operation is more Convenient；No side handwheel when, be covered with dust cap in worm screw exposed end, during installation side handwheel, at the installing hole of outside setting closure, Said two devices all play dustproof and waterproof effect it is ensured that the normal use of actuator.

Preferably: described adapter sleeve is fixed with the second handwheel by check ring and soket head cap screw.

Preferably: described closure is adopted with the second handwheel threadeds.

Preferably: described dust cap is fixedly connected with the casing by screw.

Specific embodiment

For content of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following examples specifically Bright as follows:

Referring to Fig. 1, the utility model includes housing 2, is vertically arranged with output shaft in housing 2, covers in the middle part of output shaft It is provided with worm gear, is provided with the first handwheel 1 above output shaft, also include controlling the handle 4 of electric and hand conversion, also include level Setting and worm wheel worm screw 5, described worm screw 5 one end is connected with motor 3, and described worm screw 5 other end passes through housing 2, It is covered with dust cap 6 worm screw 5 exposed junction is dismountable, prevent water or dust from entering into inside actuator, impact actuator Normal use, in the case of larger in moment of torsion, passes through housing 2 by worm screw 5, achievable manual control worm screw 5, thus drive Worm gear drives output shaft work, compared with traditional the first handwheel 1 control output shaft, can greatly save manpower.

Referring to Fig. 2, when needing Non-follow control worm screw 5 operation output shaft, can be in the exposed junction connect setting second of worm screw 5 Handwheel 7 is to realize Non-follow control worm screw 5；Referring to Fig. 4, be connected with the installing hole of the second handwheel 7 inner side for snail The adapter sleeve 8 that bar 5 connects, described adapter sleeve 8 is the cubic inner hole structure passing through for worm screw 5；Referring to Fig. 3, the utility model is also Including the closure 9 being detachably arranged at the second handwheel 7 outside installing hole.

Described adapter sleeve 8 passes through check ring and soket head cap screw and the second handwheel 7 is fixing.Described closure 9 and second-hand Wheel 7 adopt threaded, described closure 9 external screw threads tighten together with the second handwheel 1 internal thread.Described dust cap 6 passes through spiral shell Nail is fixedly connected with housing 2.

The utility model devises both hands wheel construction, runs into and needs manually operated situation, if larger first handwheel of moment of torsion 1 is no When method band movable valve rotates, then side handwheel (second handwheel 7) may be selected and is operated, worm screw 5 and worm gear reducer ratio for 31/2, snail Wheel is consistent with output shaft output.The parts that the utility model adopts are less, and structure is simple, and easy accessibility is easy to regular maintenance, And it is little to take up room, processing cost is low, high working efficiency.
