Abstract
The utility model discloses a door opening mechanism of a mine-used flame-proof type medium voltage frequency control device. An upper dynamic shaft sleeve is welded on the bracket of the upper dynamic shaft sleeve on the top of the flame-proof door; a upper static shaft sleeve which is corresponding to the upper movable shaft sleeve is welded on the bracket of the upper static shaft sleeve on the top of a door frame; the upper end of the door opening shaft is sleeved in the upper static shaft sleeve and the upper static shaft sleeve; a lower dynamic shaft sleeve is welded on the bracket of the lower dynamic shaft sleeve at the bottom of the flame-proof door; a lower static shaft sleeve which is corresponding to the down-moving shaft sleeve is welded on the bracket of the lower static shaft sleeve at the bottom of the door frame; the lower end of the door opening shaft is sleeved in the lower static shaft sleeve and the lower static shaft sleeve. With the door opening mechanism of the flame-proof type medium voltage frequency control, the two brackets of the dynamic shaft sleeve are pre-welded on the top and the bottom of the left side of the door, which are added with a plane with the door during finish turning; the door opening mechanism ensures that the central line of the door opening shaft is parallel with the fluctuate vertical line on the flame-proof plane.
Description
Technical field
The utility model belongs to a kind of flame-proof mine medium voltage converter arrangements for speed regulation, particularly a kind of flame-proof mine medium voltage converter arrangements for speed regulation door extractor structure.
Background technology
The various flame-proof mine medium voltage converter arrangements for speed regulation door extractor structures of present employing, it is parallel with the very difficult assurance of the last drop wire on the quick operating valve explosion suppresion surface that it opens the door-hinge center line, has angle to produce stress, causes an inclined to one side and difficulty of opening the door.In addition, component mostly are foundry goods, and complex contour, low precision, machining benchmark be difficult to be determined, coarse not attractive in appearance, are difficult to guarantee technical requirements and product quality.And, mechanism and door bolton, loosening easily, produce potential safety hazard.
Summary of the invention
The purpose of this utility model provides that a kind of to open the door-hinge center line parallel with the last drop wire on the explosion suppresion surface, does not have angle and produces stress, can make the flame proof door open flame-proof mine medium voltage converter arrangements for speed regulation door extractor structure easily.
For achieving the above object, solution of the present utility model is: a kind of flame-proof mine medium voltage converter arrangements for speed regulation door extractor structure, by the flame proof door, doorframe, open door-hinge, eccentric wheel handle is formed, be welded with the moving axis cover on the last moving axis cover bearing on described flame proof door top, be welded with last dead axle cover on the last dead axle cover bearing on described doorframe top with last moving axis cover corresponding matching, described upper end of opening door-hinge is socketed in moving axis cover and the last dead axle cover, be welded with down the moving axis cover on the following moving axis cover bearing of described this flame proof student portion, be welded with the following dead axle cover that overlaps corresponding matching with following moving axis on the following dead axle cover bearing of described doorframe bottom, described lower end of opening door-hinge is socketed in down in moving axis cover and the following dead axle cover.
Adopt the above-mentioned flame-proof type medium voltage converter arrangements for speed regulation door extractor structure of using, two moving axis cover bearings are welded in the door left side up and down in advance, add an individual plane with door while finish turning, and it is parallel with the last drop wire on the explosion suppresion surface to guarantee to open the door-hinge center line.Change bolton and be welding.Changing all foundry goods is machined piece, guarantees part processing precision and installation accuracy, reduces manufacture difficulty and manufacturing cost, makes that whole door extractor structure is simple, flexible operation, reliable, attractive in appearance.Two moving axis cover bearings with finish turning processing are datum, and two moving axis covers are guaranteed vertically to be welded on one heart on the moving axis cover bearing, and moving axis cover bearing location can guarantee that two moving axis cover is with one heart vertical, make two moving axis cover center line guarantee how much requirements.Two dead axles covers and two moving axis covers are through at open on the door-hinge, adjust quick operating valve flame proof gap after, two dead axle covers are welded on the quick operating valve doorframe support on the case, it is vertical concentric to guarantee that two dead axles cover and two moving axis overlap, and can not produce angle stress.Make the mechanism action flexibility and reliability, it is difficult definite to eliminate other similar door extractor structure machining benchmark, and assembly difficulty is big, opens the drawback of a difficulty.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, this flame-proof mine medium voltage converter arrangements for speed regulation door extractor structure, its eccentric wheel handle 11 is arranged on flame proof door 13 sidepieces, be welded with moving axis cover 1 on the last moving axis cover bearing 9 on described flame proof door 13 tops, be welded with the last dead axle cover 10 that overlaps 1 corresponding matching with last moving axis on the last dead axle cover bearing 2 on described doorframe 14 tops, described upper end of opening door-hinge 4 is socketed in moving axis cover 1 and the last dead axle cover 10, be welded with down moving axis cover 5 on the following moving axis cover bearing 12 of described these flame proof door 13 bottoms, be welded with the following dead axle cover 6 that overlaps 5 corresponding matching with following moving axis on the following dead axle cover bearing 7 of described doorframe 14 bottoms, described lower end of opening door-hinge 4 is socketed in down in moving axis cover 5 and the following dead axle cover 6, and described bottom of opening door-hinge 4 also is provided with opens door-hinge stop collar 8.The above-mentioned cover 5 of moving axis down overlaps 6 contact surfaces that cooperate for milling scarce face with following dead axle, when the flame proof door is normally closed, both interlock along milling scarce face, open door at present dead axle cover 6 prolong to mill to lack and promote quick operating valve towards last slip, moving axis cover 5 mills the lower sections that lack face and overlaps with following dead axle and can turn to open when 6 upper sections that mill scarce face overlap instantly.Above-mentioned down moving axis cover 5 mills the lower sections that lack face and mills the upper sections that lack face with following dead axle cover 6 and be processed into circular arc, reduces the friction of slip relatively.
