1, this operating unit takes up room greatly, and each drive disk assembly is installed on the walking on stage of hoisting crane in the mode of floor plan;
2, this operating unit transmission chain length, link is many, efficient is low, one of them link breaks down, then whole mechanism will lose efficacy;
3, the electrical motor of this operating unit, retarder, drg all by base be fixed on walk on stage on, steady for guaranteeing mechanism driving, requiring walks on stage has preferably rigidity, and annex (such as stand, protective cover etc.) is more, therefore makes complete machine weight heavier;
4, as installation deviation is large or the rigidity of walking on stage is relatively poor, with causing the larger relative displacement of generation between retarder slow-speed shaft and the axletree, affect the engagement of Full-gear coupler, reduce its service life, have certain potential safety hazard.
For existing problem in the above-mentioned prior art, a kind of novel bridge crane operating unit of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the objective of the invention is a kind of novel bridge crane operating unit of research and design.Exist in the prior art in order to solve: 1, the existing structure volume is large, large with the space; 2, operating unit transmission chain length, link is many, efficient is low, is prone to fault; 3, annex is many, causes complete machine weight large; 4, mechanism driving is to problems such as the stiffness requirement height of walking on stage.
Technical solution of the present invention is achieved in that
Bridge crane operating unit of the present invention is comprised of electrical motor, drg, retarder, brake wheel coupler and set of wheels; It is characterized in that electrical motor and drg are fixed on the housing of retarder by link span, drg places link span, and electrical motor is connected with the high speed shaft of retarder by the brake wheel coupler, and guarantees right alignment; The retarder low-speed output shaft is sleeved on the axle of set of wheels; One end of moment arm is loaded on the housing of retarder, and the other end is loaded on the group frame end beam of set of wheels, plays fixation.
Retarder of the present invention is hollow flat key shaft vertical retarder, and its low-speed output shaft is hollow flat key axle, and hollow flat key axle sleeve is contained on the axle of set of wheels, and retarder drives axletree rotating drive wheel, realizes the hoisting crane motion of translation.
The rigid frame that link span of the present invention is comprised of interior drafting board, outer panel, base plate and upper plate four block plates, interior plate processing bolt hole links to each other with retarder by reamed bolt, and outer panel processing rim of the mouth is in order to install electrical motor; Backing plate is welded on the base plate, and drg is loaded on the backing plate; For guaranteeing the installation of drg, the upper plate width is less than base plate.
Electrical motor is by the high speed shaft of brake wheel coupler driving retarder, and the retarder low-speed output shaft is hollow flat key axle, and hollow flat key axle sleeve is contained on the axle of set of wheels, and retarder drives axletree rotating drive wheel, realizes the hoisting crane motion of translation.
Advantage of the present invention is apparent, is mainly manifested in:
1, simple, the three-dimensional space of mechanism construction of the present invention is arranged, take up room little, lightweight, cost is low;
2, arrangement of mechanism of the present invention is compact, traditional link is few, reliability is high, high efficiency;
3, retarder of the present invention is sleeved on the axletree, installs and fixes by moment arm, and electrical motor, drg are fixed on the reducer shell by link span, mechanism and structure spare onrelevant, and the distortion because of structure does not affect mechanism driving;
4, the whole processing of link span of the present invention, mechanism's setting accuracy is high, stable drive;
5, drive part of the present invention has the advantage of three-in-one retarder, but electrical motor, drg, retarder, the coupler of comparing this mechanism with three-in-one retarder independently arrange, can keep in repair separately, change, and is more convenient for the O﹠M in later stage.
The present invention have novel structure, simple in structure, volume is little, lightweight, cost is low, efficient is high, safe and reliable, be convenient to the advantage such as maintenance, it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
