Abstract
The invention provides a manual and electric automatic switching device of an electric actuator. The manual and electric automatic switching device comprises an integrated manual pin, a cam and a handle sheath, the handle sheath is arranged, below an operating handle, on the integrated manual pin, and the cam is arranged below the handle sheath. The manual and electric automatic switching device has the advantages that a low-efficiency existing mode that a hand wheel is pulled out manually and pushed in electrically is changed into a mode that an output shaft of a worm wheel is driven directly by a cam driving worm to complete manual and electric automatic switching of the electric actuator, so that working efficiency is improved and personal safety of on-site operating personnel is guaranteed; the manual and electric automatic switching device has the advantages of simple structure, small number in part, convenience in mounting and demounting, convenience for daily maintenance, small occupied space, low processing cost, high working efficiency and the like.
Description
Technical field
The invention belongs to the clutch change-over device field, especially relate to a kind of manual and electronic automatic switching control equipment of electric actuator.
Background technique
Be equipped with the electric and manual manipulation COMM communication in the electric valve actuator, be used for when electronic do-part can't be worked, carrying out manual manual control.In the prior art, for the electric actuator with automatic clutch function, need for some reason to change that to turn round and stretch out the hand moving state be possible, but transfer process is more loaded down with trivial details, and common mode of operation is that handwheel is outwards pulled out and is manually-operable, pushes to be electric operating, directly drive worm screw and drive turbine output shaft, there is inefficiency in this operation, the increasing that takes up room, and be not easy to technical problems such as regular maintenance.
Summary of the invention
The problem to be solved in the present invention provide a kind of electric actuator simple in structure, easy to use manually with electronic automatic switching control equipment, be particluarly suitable for having in the electric actuator of clutch function and use.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of manual and electronic automatic switching control equipment of electric actuator, comprise the manual bearing pin of one, cam and handle sheath, the below that is positioned at operating grip on the manual bearing pin of described one is provided with described handle sheath, and the below of described handle sheath is provided with described cam.
Further, described cam is provided with support, and described support is provided with torsion spring, and described support and torsion spring are fixed on the cam by the cam bearing pin, described cam be fixed on the manual bearing pin of one by jackscrew and with vertical setting of the manual bearing pin of one; Described handle sheath comprises sheath shell, be provided with the extension spring support in the described sheath shell, described extension spring support is provided with extension spring, described extension spring is fixed on the extension spring support by screw, described sheath shell is rotatably connected by key and the manual bearing pin of one, the below of described sheath shell is provided with disc spring retaining pad, the below of described disc spring retaining pad is provided with the retaining pad, the position that is used for the positioning sheath housing, described retaining pad is provided with plain cushion, described plain cushion is provided with the bullet pad, and described retaining pad, plain cushion and bullet pad link to each other by the manual bearing pin of screw and one.
Further, the connecting part of the upper end of described sheath shell and the manual bearing pin of one is provided with lip-type packing, solves the problem of sealing.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, having changed former efficient lower handwheel outwards pulls out and is manually-operable, push and be electric operating, directly drive the mode that worm screw drives the output shaft of turbine by cam, finish the manual and electronic automatic switchover of electric actuator, improve working efficiency, guaranteed site operation personnel's personal safety; Have simple in structure, component are few, easy accessibility, be convenient to regular maintenance, little, advantages such as processing cost is low, working efficiency height take up room.

Embodiment
As shown in Figure 1, manual and the electronic automatic switching control equipment of a kind of electric actuator of the present invention, comprise the manual bearing pin 1 of one, cam 2 and handle sheath, the below that is positioned at operating grip on the manual bearing pin 1 of described one is provided with described handle sheath, and the below of described handle sheath is provided with described cam 2.
Described cam 2 is provided with support 3, and described support 3 is provided with torsion spring 4, and described support 3 and torsion spring 4 are fixed on the cam 2 by cam bearing pin 5, described cam 2 be fixed on the manual bearing pin 1 of one by jackscrew 6 and with the manual bearing pin 1 vertical setting of one; Described handle sheath comprises sheath shell 7, be provided with extension spring support 8 in the described sheath shell 7, described extension spring support 8 is provided with extension spring 9, described extension spring 9 is fixed on the extension spring support 8 by screw 10, described sheath shell 7 is rotatably connected by key 11 and the manual bearing pin 1 of one, the below of described sheath shell 7 is provided with disc spring retaining pad 12, the below of described disc spring retaining pad 12 is provided with retaining pad 13, the position that is used for positioning sheath housing 7, described retaining pad 13 is provided with plain cushion 14, described plain cushion 14 is provided with bullet pad 15, described retaining pad 13, plain cushion 14 links to each other by the manual bearing pin 1 of screw 10 and one with bullet pad 15.
Further, the connecting part of the manual bearing pin 1 of the upper end of described sheath shell 7 and one is provided with lip-type packing 16, solves the problem of sealing, refills after the present invention can assemble outside casing to be fitted in the casing.
The working procedure of this example: described cam 2 links to each other with slide block in the casing, the manual and auto state of lifting control by slide block, slide block rises to manual state, it is motoring condition that cam and slide block break away from, when the need manually-operable, depress one handle bearing pin 1 and coil to start to take turns and hang up clutch, namely realize manual state, when needing electric operating, as long as starting electrical machinery handwheel moment throws off automatically, the manual bearing pin 1 of one is got back to electronic position automatically, namely reaches motor driving state (handwheel is in neutral gear position), and has realized manual and electrically operated automatic switchover.
More than one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
