Abstract
The utility model relates to an electric operator, in particular to a flame-proof electric operator suitable for working under explosive atmosphere. The electrical operator comprises a retarder having a cabinet, a position locator, a travel limiter, and a electromotor having a housing and a rotating shaft, wherein said position locator and travel limiter are both fixedly installed in the retarder; the cabinet of the retarder is provided with a cabinet cover having space with the cabinet, the upside of the retarder is provided with an epoxy resin-sealed observation window; and a backside cover is provide outside the housing of the electromotor, and spaces are both provided among the backside cover, rotating shaft and housing. The operator has the advantages of reliable flame-proof performance, fulfillment to on-site operational requirements, compact structure, low cost, and convenient processing method. The utility model has broad market prospect and can be widely used in petroleum engineering and chemical engineering fields.
Description
Technical field
The utility model relates to a kind of electric operator, particularly a kind of flame-proof type electric topworks of working under explosive atmosphere of being suitable for.
Technical background
Traditional electric operator constitutes by speed reduction unit, position locator, overstroke safety device and motor four big individual components assemblings, and all there is not explosion separation structure the complete machine outside.Owing to be easy to generate electric spark during the electric operator internal work,, cause dangerous accident to take place if explosion hazard gases is lighted in (as oil, chemical industry etc.) work under containing explosive atmosphere in the external world easily.
Summary of the invention
In view of the deficiency that above-mentioned prior art exists, the utility model provides a kind of explosion separation structure that has, and is suitable for the flame-proof type electric topworks of working under explosive atmosphere.This installs not only flame proof reliability height, can satisfy on-the-spot request for utilization, also has characteristics such as compact conformation, low, the convenient processing of cost simultaneously, and therefore, the electric operator that has the flame proof function has vast market prospect.
The technical scheme that the utility model is taked is: a kind of flame-proof type electric topworks, it comprises the speed reduction unit that contains casing, also comprise position locator, overstroke safety device and have shell and the motor of rotating shaft, it is characterized in that: described position locator and overstroke safety device all are fixedly mounted in the speed reduction unit; The casing of described speed reduction unit be provided with and casing between leave the case lid in gap, the top of speed reduction unit also is provided with the inspection hole by epoxy sealing; The shell of described motor is equipped with rear end cap outward, all leaves the gap between rear end cap and rotating shaft and the shell.
The utility model has increased the flame proof function on traditional electric operator, promptly increased reductor case lid, reductor inspection hole, motor back header structure.And in strict accordance with national explosion-proof criteria designed between reductor casing and the case lid, gap size between motor back header and rotating shaft and the motor casing.Owing to increased explosion separation structure, thereby avoided electric operator, lighted explosion hazard gases easily and cause unsafe problems, therefore can be widely used in fields such as oil, chemical industry at work because of producing spark.
