Among the figure: 1, end carriage 2, reductor 2 ' reductor 3, reel 3 ', reel 4, girder 4 ', girder 5, motor 5 ', motor 6, drg 7, high speed shaft 8, slow-speed shaft 9, fixed pulley 9 ' fixed pulley 10, movable pulley 10 ' movable pulley
The specific embodiment
See Fig. 1-Figure 16, the novel dolly of crane in bridge type, comprise by two butt beams 1 and one or two girders 4 and form dolly crane span structure, dolly wheel, motor 5, reductor 2, reel 3, drg 6, high speed shaft 7, slow-speed shaft 8, fixed pulley 9, movable pulley 10, the novel dolly list of crane in bridge type hook is made up of two butt beams 1 and a box girder 4, and one-tenth I font structure (Fig. 1-Fig. 6).Double hook is formed (girder 4 and girder 4 ') by two butt beams 1 and two box girders, and one-tenth II font structure (Fig. 7-Figure 12).Wherein, box girder 4 and girder 4 ', end carriage 1 adopts U shaped steel to make, and can realize that disposable being installed carry out machine up, improves the assembly precision and the driving efficiency of dolly.
The dolly wheel diameter is 200-400mm, and angle bearing case that need not be traditional directly is assembled on the end carriage by the machine up to end carriage, reduces monkey track and the headroom degree above the end carriage effectively, thereby has reduced the headroom degree of dolly.
Being connected of end carriage 1 and girder 4 can adopt end carriage 1 to close the three kinds of modes that are connected with girder 4 weldings, girder 4 and the welding of end carriage 1 cover plate lap, girder 4 and end carriage 1 bolt handle, wherein, end carriage 1 and girder 4 butt welds adopt steel plate to fillet weld, improved weld strength, reduce welding stress concentration, dwindled welding deformation; Bolt is all selected high strength bolt for use closing connection, has improved end carriage 1 greatly and has docked quality with girder 4.
Reel 3 is arranged in girder 4 one sides, and an end is connected with reductor slow-speed shaft 8; Motor 5 and drg 6 are arranged in (Fig. 2, Fig. 4, Fig. 8, Figure 10) or girder opposite side (Fig. 6, Figure 12) on the girder 4, and reductor high speed shaft 7 links to each other by coupler with the transmission shaft of motor 5, and coupler is the brake wheel of drg 6; See Fig. 1-Figure 12, fixed pulley 9 is installed on the girder 4, be connected with the movable pulley 10 and the reel 3 of below by steel rope.See Fig. 7-Figure 12, in the double hook structure, girder 4 ' be provided with motor 5 ', by reductor 2 ' connection reel 3 '.
When arranging actuating device,, reductor 2 can be arranged in (Fig. 2, Fig. 8) or end carriage 1 outside (Fig. 4, Fig. 6, Figure 10, Figure 12) on the end carriage 1 according to the version of trolley frame.Reduce the headroom degree of monkey.When reductor 2 is arranged on the end carriage 1 end face, can select three fulcrum reductors 2 for use, girder 4 is reduced with motor 5 and drg 6, this kind method is to the reductor 2 (hoisting capacity is at the dolly below 80) of different capacity, ascending, can fall maximum 100mm to 200mm and not wait, but reel 3 can not descend.If reductor 2 is arranged in end carriage 1 outside, motor 5 and drg 6 are arranged in girder 4 one sides, and reel 3 so, reductor 2, and motor 5, drg 6 can descend together, and the decline maxim can reach the height value of end carriage 1.
Reel 3 can adopt two kinds of forms with being connected of reductor 2: a kind of is that drum shaft is connected with reductor low speed end sleeve type, and another kind is that the traditional type toothed disc type connects; Fixed pulley 9 is installed on the girder 4, and fixed pulley 9 links to each other with the movable pulley 10 of below and the reel 3 of side top respectively by steel rope.Fixed pulley 9 diameters are designed to D/d 〉=10, and D/d ≈ 16, fixed pulley 9 can adopt two kinds of installation forms, see Figure 13, Figure 14, fixed pulley 9 is installed in girder 4 both sides, and grooving is parallel with cylinder axis, multiplying power is an even number, wrapping phenomena do not occur intersecting between fixed pulley 9 and the movable pulley; See Figure 15, Figure 16, fixed pulley 9 is installed in girder 4 inside, no matter be that fixed pulley 9 or movable pulley 10 all are two rows, the concentrated load with girder 4 is divided into the stress point that two places equate like this, has reduced the maximal bending moment value of girder 4.
Because to the improvement of fixed pulley mechanism, the utility model has been done suitable increase with multiplying power than the tradition regulation, the reel lengthening, wirerope diameter reduces, the motor start-up torque reduces, and can select the little motor of seat No. like this for use, helps reducing the layout of the height and the actuating device of dolly.
The utility model dolly can adopt low clearance and two kinds of mounting meanss of ultralow headroom as required: the installation of low clearance, only reduce girder 4 height, and the high speed shaft 7 of reductor 2 is located at girder 4 tops; Ultralow headroom, the high speed shaft 7 of reductor 2 and slow-speed shaft 8 are arranged on girder 4 both sides, and will highly drop to desired location.By adopting this dual mode, the dolly height is effectively reduced, satisfied work requirements to a certain extent.
For expendable weight, increase reliability, the utility model has adopted steel reel 3, is welded by steel pipe.The type of attachment of reel 3 and reductor 2, a kind of is that 3 on reel is connected with reductor 2 low speed end sleeve types, another kind is the connection of traditional type toothed disc type.We are controlled at the extrusion stress of reel 3 below the 12000N.According to the different condition of customer requirements, can design each size of reel 3 at random, reach needed effect.
The utility model adopts three-in-one single group or two groups of drive systems, takes full advantage of the space of trolley frame. Output shaft adopts cover The dress formula is installed easily. Wheel diameter is more much smaller than the tradition regulation, and it is little to embody New type crane dolly volume. and lightweight Characteristics.
