Abstract
The utility model belongs to bridge erecting machines, and particularly relates to a rotating mechanism for a segment girder bridge erection machine, which can hoist and rotate girders in the air. The rotating mechanism comprises a motor reducer, a pinion wheel matched with the output shaft of the motor reducer, and a gearwheel forming a transmission pair together with the pinion wheel, wherein the motor reducer is fixed on a movable pulley holder; the axle center of the gearwheel is fixedly assembled with a shaft lever; and the shaft lever axially penetrates the movable pulley holder and is in running fit with the upper side and the lower side of the movable pulley holder. The utility model solves the problem in the prior art that the motor cable has much possibility of winding, and has the advantages that the motor can rotate forwards and backwards optionally at arbitrary angles; and the rotating mechanism has a simple structure.
Description
Technical field
The utility model belongs to the bridge formation machine, is meant that especially a kind of beam sheet of slinging needs the sections beam bridge formation machine rotating mechanism of rotation aloft.
Background technology
Present existing rotating mechanism, a kind of rotation for hoisting heavy adopts rotating part on elevator, and elevator rotating band weight rotates together, and this structure will cause rotating part bigger, complex structure; Another adopts electric rotating machine to be fixed on the rotating part, gear wheel maintains static, pinion is realized rotation around gear wheel, and the cable that said mechanism exists electric rotating machine will rotate with motor, if certainly will cause the problems such as winding of cable towards a direction rotation always.
The utility model content
The purpose of this utility model be to provide a kind of can forward and reverse random rotation, the anglec of rotation is unrestricted, sections beam bridge formation machine rotating mechanism simple in structure.
Overall technology design of the present utility model is:
Sections beam bridge formation machine rotating mechanism, comprise motor reducer 6, be matched with the pinion 12 of motor reducer 6 output shafts, gear wheel 10 with pinion 12 formation transmissions, motor reducer 6 is fixed on the movable pulley frame 5, the axle center of gear wheel 10 fixedly is equipped with axostylus axostyle 2, and axostylus axostyle 2 passes movable pulley frame 5 vertically and up and down adopts and be rotatably assorted in both sides with it.
Concrete technical construction of the present utility model also has:
Be rotatably equipped with pulley 1 on the movable pulley frame 5.
Pulley 1 is that pulley 1 is rotatably assorted on movable pulley frame 5 by bearing pin 11 with movable pulley frame 5 preferred assembling modes.
Can it is evident that axostylus axostyle 2 is rotatably assorted by bearing and movable pulley frame 5.
For guaranteeing the axial location of axostylus axostyle 2, the axostylus axostyle 2 end secure fit that are positioned at self-aligning thrust roller bearing 4 tops have nut 3.
Pinion 12 is that pinion 12 is fixedlyed connected with the output shaft of motor reducer 6 by key with motor reducer 6 preferred assembling modes.
For comparatively stably realizing the assembling of motor reducer 6, preferred mode is that motor reducer 6 fixedly is assemblied on the motor cabinet 7, motor cabinet 7 and the 5 fixing assemblings of movable pulley frame.
The utility model is work like this:
Motor reducer 6 drives pinion 12 rotations, and being meshing with each other by pinion 12 and gear wheel 10 drives gear wheel 10 rotations, and gear wheel 10 drives axostylus axostyle 2 rotations; By a series of transmission the most at last the rotation of motor reducer 6 be converted into the rotation of axostylus axostyle 2, thereby realize the rotation of hoisting heavy.
The obtained technological progress of the utility model is:
