Detailed description of the invention
nullEmbodiment is described in detail in conjunction with the figures above，As shown in Figure 1，The center of trolley frame 1 is fixed with sleeve 3，The two ends of described sleeve are provided with bearing chamber，Upper bearing is provided with pressure bearing in room，It it is carrying bottom hanging beam 17、Electric block 15 and the deadweight of rotating beam 13 and lift heavy，Deep groove ball bearing 19 is installed in lower bearing room and fixes with jump ring，Bear wheeling mechanism 2 or the traveling mechanism of the larger traveller inertia force from horizontal direction，Rotary shaft 12 is through the deep groove ball bearing of described lower cartridge，Cross section under described axial rotary is square and coordinates with the square hole in the middle of rotating beam 13，Described rotary shaft 12 is stepped，Screw thread is arranged at top，For fixing gear wheel with nut，Gear wheel 4 flat key is connected with rotary shaft，Top, axle rank still further below is used for positioning gear wheel，The bottom on axle rank is provided with pressure bearing，The adjacent place of described gear wheel is welded with rotational deceleration machine base 11，Rotational deceleration machine 8 is installed on it，The top of described rotational deceleration machine is provided with electric rotating machine 7，Little gear 9 is installed on the output shaft of reductor，Bottom is fixing and gear wheel engagement rotation with jump ring，Described rotating beam 13 center has rectangular opening to match with rotary shaft，On rotating beam 13 lower cover, two ends, left and right are respectively welded with and hang nose，It is connected by drift bolt with the hanger on electric block 15，The centre of described lower cover is provided with equalizer pulley group 22，Steel cable is shared for two electric blocks centered by equalizer pulley group.
The main structure of described trolley frame 1 is made up of two end carriages and two longerons, the two ends of two butt beams are equipped with 4 wheel groups, two adhesion wheel two driven wheels, the fluted disc of adhesion wheel group is meshed with the little gear of trolley travelling reductor, runs by running reductor band motor car wheel.Two longerons are respectively welded at the two ends of dolly end carriage, form fixing quadrangle.
Described sleeve 3 is positioned at the center of trolley frame, two crossbeams and two longerons form right-angled intersection, sleeve is fixed on the center of trolley frame.There is bearing chamber at two of sleeve, pressure bearing 6 is installed in upper bearing room, it is primarily subjected to bottom hanging beam 17, cucurbit, the deadweight of rotating beam 13 and lift heavy, deep groove ball bearing 19 is installed in lower bearing room, bottom is also fixed with jump ring, being primarily subjected to trolley travelling or cart runs the horizontal force caused, the top of sleeve is equipped with upper fixing round nut 5, and end is equipped with lower fixing round nut 20.
Described rotary shaft 12 is stepped, all there is screw thread upper and lower, top threaded portion is downwards gear wheel 4 installation position, it is connected with gear wheel with flat key, being axle rank still further below, the top on axle rank is used for positioning gear wheel, the bottom location and installation pressure bearing 6 on axle rank, make axle rank be pressed in the upper plane of pressure bearing, bear bottom hanging beam 17, cucurbit 15, the deadweight of rotating beam and lift heavy.This axle 2 ~ 3mm less than the internal diameter of sleeve with sleeve mating part, prevents also sleeve from rubbing.Through the deep groove ball bearing 19 of lower cartridge, downward cross section becomes square, and this part coordinates with the square hole in the middle of rotating beam, so when this axle rotates, beam can be rotated and rotate together.The screw thread of the foot of this axle is to fix rotating beam with lower fixing round nut, does not allow it fall.After gear wheel assembles with flat key also rotary shaft, use fixing round nut 5 and be fixed.
The side of gear wheel is welded with rotational deceleration machine base 11, and the center of this base is the centre-to-centre spacing of two gears.Rotational deceleration machine 8 is installed on this base top, and fixes bolt group with rotational deceleration machine and fixed by reductor, and motor 7 is installed on the top of reductor, and motor output shaft is connected with the power shaft of reductor, is fixed on reductor by motor by bolt group 10.Little gear is arranged on the output shaft end of reductor, and bottom jump ring is fixed, and is allowed to engage with gear wheel.
Described rotating beam is the box-structure of Plate Welding, and there is rectangular opening at center, matches with rotary shaft, welds reinforcing plate, improve the contact area with rotary shaft, make extrusion stress reduce on the upper cover plate and lower cover of this position.On the lower cover of this beam, the right and left respectively welds one and hangs nose, and each hanging is respectively arranged with two holes on nose, and the size in hole, as the hole on electric block hanger, is hung nose with the hanger of 14 two electric blocks 15 of drift bolt with this and coupled together.So, two electric blocks have just been suspended on two of this rotating beam.The centre of this beam lower cover is provided with equalizer pulley group 22, two electric blocks thus can be made to share steel cable, advantage of this is that and solve lifting motor because as the problem of revolutional slip makes lifting velocity not exclusively, so use long and hanging beam two of bottom will be made different high phenomenon to occur, at this moment have only to rotary balance pulley, just can adjust the height on hanging beam both sides.
Described hanging beam is the box-structure of Plate Welding, and one group of running block 16 is respectively installed at upper cover plate two, and a suspension hook group 18 is respectively installed at two of lower cover, and suspension hook group bearing pin is connected with this hanging beam, for lifting by crane the weight of bottom.The steel wire rope 21 got off on an electric gourd drum the most from which, down around one end running block 16 on this beam, then up around equalizer 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 run on girder, and electric block pulls the raising and lowering of hanging beam by being wound around and discharging steel wire rope, thus pulls the raising and lowering of weight.When weight needs to rotate, start electric rotating machine, the deceleration rotating through reductor of motor, drives the rotation of the little gear of output end of reducer, little gear to be meshed with dress gear wheel on the rotary shaft, the rotation of gear wheel, the rotation of axle is rotated, rotating further through the rectangular interface with rotating beam, the rotation of the rotating beam of drive of rotary shaft by flat key, the following electric block of rotating beam has just driven the rotation of hanging beam by steel wire rope, and such weight can be realized as rotating.
