Embodiment
Embodiment is described in detail with reference to the figures above, as shown in figure 1, the center of trolley frame 1 is fixed with sleeve 3, institute
The bearing chamber that is provided at both ends with of sleeve is stated, upper bearing is provided with pressure bearing in room, be carrying bottom hanging beam 17, electric block
15 and deadweight and the lift heavy of rotating beam 13, deep groove ball bearing 19 is installed in lower bearing room and fixed with jump ring, dolly is born
The inertia force of travelling mechanism 2 or traveling mechanism of the larger traveller from horizontal direction, rotary shaft 12 passes through the deep-groove ball of the lower cartridge
Section under bearing, the axial rotary be square and rotating beam 13 in the middle of square hole coordinate, the rotary shaft 12 be it is stepped,
Screw thread is arranged at top, for fixing gear wheel with nut, and gear wheel 4 is connected with flat key with rotary shaft, and axle rank top still further below is used
In positioning gear wheel, the bottom of axle rank is provided with pressure bearing, and the adjacent place of the gear wheel is welded with rotational deceleration machine base 11,
Rotational deceleration machine 8 is installed thereon, the top of the rotational deceleration machine, which is provided with electric rotating machine 7, the output shaft of reductor, pacifies
Equipped with little gear 9, bottom is fixed with jump ring has rectangular opening and rotary shaft phase with gear wheel engagement rotation, the center of rotating beam 13
Coordinate, left and right ends, which are respectively welded with, on the lower cover of rotating beam 13 hangs nose, is connected with the hanger on electric block 15 by drift bolt, described
The centre of lower cover is provided with equalizer pulley group 22, and a steel wire is shared for two electric blocks centered on equalizer pulley group
Rope.
The main structure of the trolley frame 1 is made up of two end carriages and two longerons, and the two ends of two butt beams are equipped with 4 wheels
Group, the driven wheel of two adhesion wheel two, the fluted disc of adhesion wheel group is meshed with the little gear of trolley travelling reductor, passes through fortune
Row reductor band motor car wheel is run.Two longerons are respectively welded at the two ends of dolly end carriage, form fixed quadrangle.
The sleeve 3 is located at the center of trolley frame, forms right-angled intersection by two crossbeams and two longerons, sleeve is fixed
At the center of trolley frame.There is bearing chamber at two of sleeve, and upper bearing room installs pressure bearing 6, is primarily subjected to bottom hanging beam
17th, deep groove ball bearing 19 is installed in cucurbit, the deadweight of rotating beam 13 and lift heavy, lower bearing room, and bottom is simultaneously fixed with jump ring, mainly
Horizontal force caused by trolley travelling or cart operation is born, the top of sleeve is equipped with upper fixed round nut 5, and end is equipped with lower fixation
Round nut 20.
The rotary shaft 12 is stepped, and there is screw thread upper and lower part, and top threaded portion is installed downwards for gear wheel 4
Position, is connected with flat key with gear wheel, is still further below axle rank, and the top of axle rank is used to position gear wheel, and the bottom of axle rank is determined
Pressure bearing 6 is installed in position, axle rank is pressed in the upper plane of pressure bearing, bears bottom hanging beam 17, cucurbit 15, the deadweight of rotating beam
And lift heavy.The axle, than the small 2 ~ 3mm of internal diameter of sleeve, prevents that also sleeve rubs with sleeve mating part.Through under sleeve
The deep groove ball bearing 19 in portion, downward section is changed into square, and the square hole in the middle of this part and rotating beam coordinates, so when the axle turns
When dynamic, rotating beam can be driven to rotate together.The screw thread of the foot of the axle is to fix rotating beam with lower fixed round nut, does not allow it
Fall.After gear wheel is assembled with flat key also rotary shaft, it is fixed with fixed round nut 5.
Rotational deceleration machine base 11 is welded with beside gear wheel, the center of the base is the centre-to-centre spacing of two gears.The bottom
Rotational deceleration machine 8 is installed on seat top, and is fixed reductor with rotational deceleration machine fixing bolt group, and electricity is installed on the top of reductor
Machine 7, motor output shaft is connected with the input shaft of reductor, and motor is fixed on reductor with bolt group 10.Little gear is pacified
Mounted in the output shaft end of reductor, bottom is fixed with jump ring, is allowed to engage with gear wheel.
The rotating beam is the box-structure that steel plate is welded, and there is rectangular opening at center, is engaged with rotary shaft, in the position
Reinforcing plate is welded on upper cover plate and lower cover, the contact area with rotary shaft is improved, reduces extrusion stress.On the lower cover of the beam
Respectively nose is hung in weldering one to the right and left, and each hanging on nose respectively has two holes, and the size in hole is used as the hole on electric block hanger
The hanger of two electric blocks 15 is hung nose with this and connected by drift bolt 14.So, two electric blocks have just been suspended on the rotation
Turn two of beam.The centre of the beam lower cover is provided with equalizer pulley group 22, two electric blocks is shared one
Steel wire rope, advantage of this is that solving the problem of lifting motor is because of revolutional slip makes lifting velocity not exclusively, so
With long hanging beam two that will make bottom may different high phenomenon occur, at this moment only need to rotary balance pulley, just
The height on hanging beam both sides can be adjusted.
The hanging beam is the box-structure that steel plate is welded, and one group of running block 16 is respectively installed at upper cover plate two, lower cover
A suspension hook group 18 is respectively installed at two, and suspension hook group is connected with bearing pin with the hanging beam, the weight for lifting by crane bottom.So from it
In the steel wire rope 21 that gets off on an electric gourd drum, down around one end running block 16 on the beam, then up around flat
Weigh pulley, still further below around to other end running block, returns another electric block up.
This rotating cart is achieved in that wheeling mechanism drives whole dolly and lift heavy to be run on girder,
Electric block pulls the raising and lowering of hanging beam by winding and discharging steel wire rope, so as to pull the raising and lowering of weight.
When weight needs to rotate, start electric rotating machine, the rotation of motor drives the small tooth of output end of reducer by the deceleration of reductor
The rotation of wheel, gear wheel of the little gear with dress on the rotary shaft is meshed, and the rotation of gear wheel drives rotary shaft by flat key
Rotate, the rotation of rotary shaft is further through the rectangular interface with rotating beam, the rotation of the rotating beam of drive, following electronic of rotating beam
Cucurbit has just driven the rotation of hanging beam by steel wire rope, and such weight can be realized as rotating.
