Abstract
The utility model provides a turning gear for a compressor. The turning gear comprises a compressor spindle big gear and a turning gear meshed with the compressor spindle big gear, wherein a deflector rod is arranged on the turning gear; a normally open turning position electromagnetic proximity switch is arranged at the position corresponding to the deflector rod; the turning position electromagnetic proximity switch is arranged in a turning control circuit; the turning control circuit comprises a turning forward rotation circuit part; the turning forward rotation circuit part comprises the normally open turning position electromagnetic proximity switch, a normally closed turning stop button and a turning forward rotation contactor; after a turning forward rotation starting button is pressed on, the turning forward rotation contactor is electrically sucked and has a self-locking function. The turning gear has the advantages that the equipment can be prevented from stopping caused by mechanical fatigue of a mechanically turning control switch; because of the use of the non-contact electromagnetic proximity switch, the abrasion caused by direct contact of a mechanical control switch can be avoided, and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to chemical technology field, especially relates to a kind of compressor barring gear.
Background technique
Methyl alcohol, as extremely important Organic Chemicals, is the basic product of carbon-chemical industry, occupies critical role in national economy.Take coke-stove gas in the reaction of raw material synthesizing methanol, compressor is the capital equipment of methyl methanol syngas supercharging, the ride quality of compressor is directly connected to the output of methyl alcohol combined coefficient and methyl alcohol.Shut down and impact production in order to prevent that compressor from breaking down, coke-stove gas methyl alcohol processed enterprise often needs to establish compressor standby equipment.And stand-by compressor is after parking for a long time, be prone to distortion, jam problem, thus starting before compressor electric motor, need to carry out jiggering to compressor, in case electric motor starting load becomes large and damages motor.Traditional compressor jiggering device; mostly use mechanically controlled switch and main motor to form electrical equipment locking; guarantee that outage state could allow jiggering; or open state can not enter jiggering and allow; otherwise can cause electric blocking to shut down; thereby the personal security when safe operation of assurance compressor and overhaul of the equipments, and mechanically controlled switch is prone to mechanical wear, causes mechanical fatigue, can not meet the demand of production.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existing in prior art, a kind of compressor barring gear is provided, the technological scheme adopting is: a kind of compressor barring gear, comprise compressor main shaft gearwheel, the jiggering gear engaging with compressor main shaft gearwheel, on jiggering gear, driving lever is housed, it is characterized in that: normal opening quotation truck position electromagnetic proximity switch is equipped with in the position of corresponding driving lever, described jiggering position electromagnetic proximity switch is contained in jiggering control circuit, described jiggering control circuit comprises jiggering prograde circuit part, described jiggering prograde circuit part comprises described normal opening quotation truck position electromagnetic proximity switch, normally closed jiggering stop button and the positive contactor of jiggering, when pressing after jiggering forward start button, the positive contactor of described jiggering obtains electric adhesive and has auto-lock function.
Technical characteristics of the present utility model also has: described jiggering control circuit also comprises jiggering motor reversal circuit part, described jiggering motor reversal circuit part comprises described normal opening quotation truck position electromagnetic proximity switch, normally closed jiggering stop button and jiggering reversion contactor, when pressing after jiggering reversion start button, described jiggering reversion contactor obtains electric adhesive and has auto-lock function.
Technical characteristics of the present utility model also has: described jiggering control circuit also comprises that main frame stops indicating circuit part, and described main frame stops the normally-closed contact of normally-closed contact that indicating circuit part comprises the positive contactor of jiggering linking together, jiggering reversion contactor and stops tutorial light.
The beneficial effects of the utility model are: 1) avoided mechanical jiggering control switch to occur mechanical fatigue and the equipment downtime that causes; 2) use contactless electromagnetic proximity switch, avoided mechanically controlled switch directly to contact and cause wearing and tearing, extended the working life of equipment.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation, wherein 1 is the truck position electromagnetic proximity switch that often opens the set, 4ST1 is normally closed jiggering stop button, and 4QS1 is jiggering forward start button, and 4QS2 is jiggering reversion start button, 4KM1 is the positive contactor of jiggering, 4KM2 is jiggering reversion contactor, and 4HG 1 is jiggering forward tutorial light, and 4HG2 is jiggering reversion tutorial light, 4HG3 stops tutorial light, and 4FR is thermorelay.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.The utility model discloses a kind of compressor barring gear, this device comprises compressor main shaft gearwheel, the jiggering gear engaging with compressor main shaft gearwheel, on jiggering gear, driving lever is housed, normal opening quotation truck position electromagnetic proximity switch 1 is equipped with in the position of corresponding driving lever, and jiggering position electromagnetic proximity switch 1 is contained in jiggering control circuit.Jiggering control circuit comprises that jiggering prograde circuit part, jiggering motor reversal circuit part and main frame stop indicating circuit part.Jiggering prograde circuit part comprises normal opening quotation truck position electromagnetic proximity switch 1, normally closed jiggering stop button 4ST1 and the positive contactor 4KM1 of jiggering, when pressing after jiggering forward start button 4QS1, the positive contactor 4KM1 of jiggering obtain electric adhesive and by itself control contact open in usual realize auto-lock function.Jiggering motor reversal circuit part comprises normal opening quotation truck position electromagnetic proximity switch 1, normally closed jiggering stop button 4ST1 and jiggering reversion contactor 4KM2, when pressing after jiggering reversion start button 4QS2, jiggering reversion contactor 4KM2 obtains electric adhesive and auto-lock function is realized in the contact open in usual controlled by itself.Except auto-lock function, in jiggering control circuit, also there is contactor back locking function, before the positive contactor 4KM1 of jiggering, connect the Normally closed type contact that jiggering reversion contactor 4KM2 controls, before jiggering reversion contactor 4KM2, connect the Normally closed type contact that jiggering forward contactor 4KM1 controls.Main frame stops the normally-closed contact of normally-closed contact that indicating circuit part comprises the positive contactor 4KM1 of the jiggering linking together, jiggering reversion contactor 4KM2 and stops tutorial light 4HG3.
When in " continuously " state, normal opening quotation truck position electromagnetic proximity switch 1 is in the time of closed state, press jiggering forward start button 4QS1, the positive contactor 4KM1 of jiggering obtains electric adhesive and self-locking, 4HG1 is bright for jiggering forward tutorial light, in jiggering forward state, now jiggering reversion contactor 4KM2 cannot obtain electric adhesive; In the time pressing jiggering reversion start button 4QS2, jiggering reversion contactor 4KM2 obtains electric and adhesive, and in jiggering inverted status, now the positive contactor 4KM1 of jiggering cannot obtain electric adhesive.
This barring gear, except " continuously " state, also can be set as " crawl " state and " stopping " state.
