The specific embodiment
Embodiment 1:
In the drawings: 1 is girder, and 2 is crane, and 3 is monkey; 4 is track, and 5 is the wheel of monkey, 6 integrated change-speed boxs; 7 is motor, and 8 is the wheel of crane, and 9 is motor; 10 integrated change-speed boxs, 12 is the kinetic energy input end of change- speed box 6,10,13 is the kinetic energy mouth of change-speed box 6,10.
The occupation mode of this enforcement and scope are identical with traditional old-fashioned crane in bridge type in the past, and below we describe being related to our innovative ideas emphatically:
Part about girder 1:
Structure originally: the wide 450mm of girder; Track is installed in the axial center of girder; Spacing between track and the girder upper cover plate all is 225mm, so, monkey (monkey wheelspan 2500mm has been installed on the girder; Monkey the widest part size 3600mm) after, the outer ledge of monkey is just concordant basically with the outer ledge of girder.For the ease of personnel's walking, just be outside equipped with steel plate and walk on stage so that walk in the girder outer rim.
The structure of present embodiment: girder 1 width is set to 950 mm, and with track 4 eccentric installations, the spacing of track 4 centers and girder 1 endosternum top flange is 110 mm; Because monkey 3 size constancies (wheelspan 2500mm, wide 3600mm) are installed like this; Girder 1 outer ledge and monkey 3 outer ledges also have the space of 780mm, enough supply person walks, have so just practiced thrift the material of walking on stage; By because of having alleviated, so its technical performance has strengthened from weight 25%.
The benefit of bringing after the increase of girder 1 width is shown that also the horizontal rigidity that makes complete machine increases.
Driver train about crane:
Original design is on the girder two ends, to install to be provided with horizontal transmission device (motor, retarder, transmission shaft, drg, coupler); Be used for driving the wheel walking on the crane, above-described loaded down with trivial details transmission device, its deadweight just have 3.7 tons surplus.
The structure of existing new design is to have cancelled original motor, retarder, transmission shaft, drg, brake wheel, coupler; Incorporate change-speed box 10 is being installed on 2 on the crane; Motor 9 is directly installed on the kinetic energy input end 12 of integrated change-speed box 10; Simultaneously, kinetic energy mouth 13 drive wheels 8 of incorporate change-speed box.Originally heavy loaded down with trivial details horizontal transmission device is cancelled, and the manufacturing cost that this just can reduce hoisting crane has alleviated the hoisting crane deadweight simultaneously.
The weight that above two parts alleviate accounts for the 25-30% of original like product, so corresponding, the rating horsepower of motor 9 also can reduce by 36.5%.We are calculated as example with the hoisting crane oepration at full load of 50 tons of hoisting capacities: conduct oneself with dignity 43 tons originally, cart operation motor 9 power are 22kw, per hour power consumption 22 degree.And conduct oneself with dignity 32 tons now, and motor 9 power are 15kw, by per hour power consumption 15 degree calculating, per hour can practice thrift electricity 7 degree, and are visible, energy-saving effect is very tangible.
Driver train about monkey:
The wheel of original monkey is to rely on a ZSC600 type vertical type speed reducer (change gear) and 7.5KW motor, transmission shaft, coupler, brake wheel, drg to drive; Such drawback is that assembly technology program complicacy is loaded down with trivial details, owing to be that (this driving system is a vacant state in aloft work; Under do not have base plate); In case overhaul or the replacing parts, will increase the difficulty of dismounting, also be unfavorable for safety.
Existing design is a driving system of having cancelled overhanging portion; But incorporate change-speed box 6 is installed on monkey 3; Motor 7 (power is 6KW) is directly installed on the kinetic energy input end 12 of integrated change-speed box 6, simultaneously, and kinetic energy mouth 13 drive wheels 5 of incorporate change-speed box 6.Such benefit is simplification and has omitted the loaded down with trivial details Installation and Debugging program of original driving system that the action of dismounting and installation motor 7 only is to twist bolt to get final product.
Embodiment 2:
Keystone configuration and manner of execution are with embodiment 1, and difference is that the spacing of track 4 centers and girder 1 endosternum top flange is 170 mm, and like this, girder 1 outer ledge and monkey 3 outer ledges also have the space of 750mm, also can supply person walks.
