The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, lifting mechanism of the present invention by be no less than three, nested, coaxial mounted sleeve leading screw 1 is formed step by step, sleeve leading screws 1 at different levels are the cannulated sleeve structure, the external surface of every grade of sleeve leading screw 1 is outer trapezoidal full thread structure, the top of the inner surface of sleeve leading screw 1 is the inner trapezoidal thread structure, the bottom is a smooth surface, and driven sprocket 1.4 is installed on the final stage sleeve leading screw.The pitch of the internal and external threads of sleeve leading screws 1 at different levels and helical pitch are all identical.
1 fen 4 point of multistage sleeve leading screw arrange that its power drive mechanism drives drive sprocket 7 rotations by motor 3 by reducer 2, and drive sprocket 7 drives driven sprocket 1.4 and rotates.The multistage sleeve leading screw 1 of per 2 covers has a reducer 2, and reducer 2 drives driven sprocket 1.4 rotations by drive sprocket 7, chain 5.Every reducer all has motor 3 direct connections to drive, and motor 3 is two shaft braking motors.For making whole device synchronization, two synchronous coupking shaft 4 rigid connections of motor 3 usefulness, coupking shaft 4 adds bearings every one section synchronously, scratches with anti-bending.Upper table surface beam parts 6 connect firmly with the upper end of the first order sleeve leading screw of multistage sleeve leading screw, and for reducing shut height, upper table surface beam parts 6 adopt the nesting type structure made from shaped steel.
The first order sleeve leading screw of diameter minimum is a solid screw, has only external screw thread, and the last grade sleeve leading screw of diameter maximum has only internal thread.
As shown in Figure 3, sleeve leading screws 1.1 at different levels are nested successively by T shape screw thread, and the spacing cover plate 1.2 usefulness sunk screws of final stage are assemblied on the upper surface of final stage sleeve leading screw 1.3.The step of the axial force of bearing is arranged at the bottom of final stage sleeve leading screw 1.3, from its underpart assembling self-aligning roller bearing 1.7; Portion assembles deep groove ball bearing 1.6 and gasket ring 1.9, oil seal cover 1.5, hinge wheel parts such as (1.4) successively from it.Hinge wheel connects firmly (drawing the figure) from wheel hub with multi-pin or multikey and final stage sleeve, with transfer torque.Final stage sleeve head portion is with two kinds of bearings bearing support (1.10) of packing into, and bearing support is used bolts assemblies with bottom pad plate (1.8) again.Bottom pad plate is fixedly coupled part as equipment and the welding of ground embedded board.
As shown in Figure 5, be the structure chart of certain grade of sleeve leading screw, spacing cover plate 1.1.2 is assemblied in two of sleeve leading screw 1.1.1 with sunk screw, prevents surpassed distance as no screw thread stop portion.The structure of Fig. 5 is sleeve leading screw wherein just, and remaining sleeve screw structure is identical.
As shown in Figure 1, multistage sleeve leading screw 1, except that first order sleeve leading screw is the solid screw, later at different levels all be the cannulated sleeve structure, its external surface is outer trapezoidal full thread structure, the top of inner surface is inner trapezoidal thread, makes nut and uses, the bottom is a smooth surface.
As Fig. 1, shown in Figure 5, the upper end of first order sleeve leading screw rises to when upper table surface beam parts 6 contact, the rotation of the upper end constraint of upper table surface beam parts 6 constraint first order sleeve leading screws, but do not retrain its rectilinear motion up and down, driven sprocket 1.4 on the final stage sleeve outer diameter continues input torque, certain grade of sleeve leading screw is rotated further, its upper level sleeve leading screw is done axially-movable, when motion makes this grade sleeve leading screw cover stroke to put in place, because the effect of spacing this plate 1.1.2 can not be stretched it again, this grade sleeve leading screw also begins to rotate, and upper level sleeve leading screw begins axial rotation again ... and the like, the sleeve leading screw is flexible step by step, can carry lifting.In the driving torque transmittance process, because pitch and helical pitch at different levels are identical, the sequencing of its rotation is unimportant, and the flexible stroke of each commentaries on classics all is consistent, until covering whole total kilometres.
As Fig. 1, shown in Figure 4, the sleeve leading screw all stretches out the back and forms pyramidal structure, and lifting load-bearing has rational stability, all has the minimum altitude structure after the withdrawal, is beneficial under the shallow condition of equipment foundation ditch installation and uses.
Because the volume height of motor has influenced the minimum altitude of equipment, so whole shared 2 motors of equipment can reduce equipment from high.
