The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of screw compression machine head maintenance platform, and it is mainly comprised of motor 1, frame 9, workbench 10, worm and worm gear 2, shaft coupling 3, bearing block 4 and bearing block 7, workbench fixed head 5, wedge shape displacement limiter 6 and electric cabinet 8.Above-mentioned each parts centralized arrangement is in a frame 9, and volume is little, and for head maintenance, applicability is strong.
An impulse stroke of workbench is 1/4 to turn, and 12 seconds consuming time of impulse stroke, guarantees the slow-speed of revolution, stable.Workbench 10 can adopt lifting workbench, effectively alleviates operating personnel's working strength.5 rotations of workbench fixed head, adopt the non-maintaining bearing block of SKF, can the maximum 340KN of bearing load.Bearing block adopts with closure design bearing, and foreign material, fragment and dust enter bearing when preventing from keeping in repair, and cause bearing failure.
Wedge shape displacement limiter 6 is comprised of two displacement limiter, and one of them displacement limiter is arranged on workbench 10 edges, and another displacement limiter is arranged on frame 9 column places.
Referring to Fig. 3 and Fig. 4, wedge shape displacement limiter 6 is comprised of wedge-shaped body 61, slide block 62 and trigger switch 11, and slide block 62 is slidably disposed in wedge-shaped body 61.Wedge shape displacement limiter is set, can effectively prevents the maintenance accident that maintenance platform causes because of maloperation, to maintenance platform, rotation is accurately located.
PLC controller and high-quality electric combination element are housed in electric cabinet 8, their integrated being arranged in a casing, casing degree of protection IP55, the foreign material while effectively preventing from keeping in repair, machine oil and moisture enter electrical system and the control section fault that causes.Automatic control system and high-quality electrical equipment combine, and have hommization, simple to operate.
According to the method for operating of screw compression machine head maintenance platform of the present utility model, by the screw compression machine head of the assembling that needs repairing, be fixed by bolts on workbench fixed head 5, start workbench 10, motor 1 drives worm and worm gear 2, worm and worm gear 2 outputs transfer torque to bearing block by shaft coupling 3, drive workbench 10 carry out 0 °～90 ° counterclockwise or turn clockwise, and to reach the horizontal vertical position of the head needing repairing, position.In running, can press at any time stop button, workbench fixed head 5 is fixed to and meets the orientation that checks and keep in repair.
Head is in assembling process, workbench 10 is placed in to horizontal level, the housing of head is fixed on workbench fixed head 5, start workbench 10, workbench fixed head 5 rotates to cocked position, screw rod negative and positive rotor is vertically fitted into head shell, adjusts molded line back lash, running in bearings, axle sleeve, shaft seal and gland etc.And then startup workbench, be inverted to level orientation, fitting machine casing tail end bearing and housing bonnet.This head maintenance platform can effectively guarantee in screw compression machine head maintenance assembling process the realization about molded line, end play important parameter.
When workbench fixed head is rotated towards vertical direction by horizontal direction, L shaped of workbench slowly contacts wedge shape displacement limiter, when slide block moves to trigger switch direction, contact trigger switch, send signal, motor quits work, and workbench fixed head is spacing at vertical position.Otherwise when workbench fixed head is rotated towards horizontal direction by vertical direction, L shaped of workbench slowly contacts wedge shape displacement limiter, when slide block is to the motion of trigger switch direction, contact trigger switch, sends signal, motor quits work, and workbench fixed head is spacing at horizontal level.If need to make workbench fixed head stop at any angle within the scope of 0 °～90 °, press shutdown switch on electric cabinet, workbench fixed head stops at the angle position that needs operation, meets the maintenance repair of arbitrary orientation.
In sum, screw compression machine head maintenance platform of the present utility model, screw compression machine head that can be based on plurality of specifications, maintenance platform operating space is large, possess versatility, the head maintenance assembling that a workbench can meet Multiple Type, takes into account flexible operation, simple.Apply screw compression machine head maintenance platform of the present utility model, fittage can be made to keep in repair more laborsaving, safer, the realization about molded line, end play important parameter can be effectively guaranteed in screw compression machine head maintenance assembling process, head performance after assembling is more excellent, and efficiency is higher.
Certainly, those skilled in the art in the art will be appreciated that, above-described embodiment is only for the utility model is described, and not with opposing restriction of the present utility model, as long as within the scope of connotation of the present utility model, the variation of above-described embodiment, modification all will be dropped in the scope of the utility model claim.
