Fig. 2 is the structural representation of the various systems that arrange on rollover stand
In figure: 1, underframe; 2, rollover stand; 3, lifting platform; 4, rotating disk; 5, guide rail; 41, turntable bearing; 6, rotary motion mechanism; 7, lifting motor; 71, screw mandrel; 72, decelerator; 8, turnover driving mechanism; 9, support adjustment structure.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the utility model in detail.
As depicted in figs. 1 and 2, rotation table device can be divided into underframe, overturn system, rotary system, jacking system, running gear, micro-tensioning system and automatically controlled part by function.The high about 4730mmX2650mmX1037.5mm of the wide X of the long X of rotation table device appearance and size, carrying 3-10t, conducts oneself with dignity approximately 7 tons.
During use, mobile device moves to desired location, and regulate and support 9 ground of adjustment structure, and leveling; Now turntable lifting platform 3 is in lowermost end; If lifting, inputs lifting numerical value, start lifting drive mechanism, lifting product puts in place; Then continue to be turned to 90 °; After putting in place, can pass through micro-adjusting mechanism, carry out three-dimensional fine setting.
The underframe 1 of turntable is the primary load bearing mechanism of rotation table device.The ball screw assembly, of overturn system and line slideway 5 pairs are symmetrical arranged on two side bars of underframe; Micro-adjusting mechanism is arranged on four jiaos of side bar outside, realizes turntable all around, upper and lower fine motion; Drive system is placed in the front end of underframe; Steering is placed in underframe rear end (electric control operation end), by quadric chain, is realized and being turned to; Rollover stand 2 is hinged by hinge and underframe 1, realizes 0 °～90 ° rotary movements, and rotary motion mechanism drives rotating disk on turntable bearing, to realize revolution action; During the electrical power of lifting drive mechanism, by decelerator, drive leading screw to rotate, by screw rotation change into lifting platform along lead rail axis to rectilinear motion, thereby drive the lifting of lifting platform straight line; On the bearing beam of underframe, be arranged symmetrically with the double transportation of four suspension centres fixing point; Turntable is the lifting for self for special hanger; Running gear Wei Fang moving vehicle mechanism and four bar linkage steering engine structure, inherited the successful experience of turntable in the past.
Turntable jacking system is mainly comprised of lifting platform, guide rail, lifting drive group (decelerator, motor, leading screw), rollover stand, displacement measuring device etc., as shown in Figure 2, lifting platform is connected with rollover stand by guide rail, leading screw, lifting drive group electrical power, driving leading screw rotates, and by slide rail and screw, rotation is changed into rectilinear motion, thereby drives lifting platform traveling priority.Lifting platform effective travel 0-1000mm.Displacement measuring device is installed in lifting platform and rollover stand appropriate location, in real time displacement is passed back to display screen, shows in real time current location, and the while to control system, realizes data feedback automatically and controls.Rising or falling speed divides third gear adjustable, and fast shelves speed is 10mm/s; Middle-grade speed is 4mm/s; slow shelves speed is 0.5mm/s; decelerator has auto-lock function; lifting platform optional position can be stopped, and location is reliable, turntable installation position displacement sensor; the displacement of the real-time observing and controlling jacking system of electric-control system; can reach ± 0.1mm of positional precision, is provided with stopping means at two limit positions, and its extreme position is carried out to safeguard protection.
In turntable jacking system, guideway plays carrying all directions moment and perpendicular to the power of the tension and compression of guide pass.Therefore, the layout of guide rail is most important.In this jacking system, guide rail is symmetric configuration all around, by quadruplet guide rail, forms this guideway, by arranging the slide block of diverse location that guide rail is only under pressure in lifting process, guarantee that guide rail stand under load is good, while making structural design, lower the risk that is spirally connected and brings simultaneously.
