On chassis frame, symmetry is installed two electric pushrods respectively, the telescopic end of electric pushrod is hinged on the fork of installing on lower splined shaft, the motor side of electric pushrod is hinged on sole, two flexible angles that change > < type hinges of electric pushrod, ride face changes the angle on relative altitude and ground thereupon.
Two synchronous sheaves have been installed respectively on two splined shafts on car table-board bracket, setting-in steel wire rope (chain) in synchronous sheave, steel wire rope (chain) tightly installs around in two synchronous sheaves and is ∞ font, steel wire rope (chain) seam must not be at the synchronous upper and lower semicircle of sheave place, steel wire rope (chain) is fixed on to two synchronous sheaves outsides with clamp, be limit, the ∞ font left and right sides half domed end (sprocket wheel and chain mounting means and synchronous sheave, steel wire rope are identical, but chain be arranged on sprocket wheel fix without clamp).
Brief description of the drawings
Fig. 1 is the present invention's structure principle chart that raises;
Fig. 2 is that the present invention reduces structure principle chart;
Fig. 3 is angle variation diagram of the present invention;
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Description of reference numerals is as follows:
1---ride face 2---fork 3---electric pushrod 4---splined shaft
5---synchronous sheave (sprocket wheel) 6---steel wire rope (chain) 7---jointed shafts
8---push-rod electric machine axle 9---chassis 10---push rod bearing pin 11---lower swing arms
12---top link 13---positioning checkpoint
Transfer car(buggy) elevating mechanism as shown in Figure 1, 1 upper symmetry of ride face has been installed four top links 12, top link 12 between two symmetry is arranged on splined shaft 4, two synchronous sheaves (sprocket wheel) 5 are also arranged on respectively on splined shaft 4, steel wire rope (chain) 6 is ∞ font tightly in synchronous sheave (sprocket wheel) 5, two synchronous sheave (sprocket wheel) 5 outsides are provided with steel wire rope (chain) 6 fixation clamps 13, top link 12 lower ends and lower swing arm 11 are hinged by jointed shaft 7, four lower swing arm 11 lower ends between two symmetry are arranged on lower splined shaft 4, lower splined shaft 4 is arranged on sole bearing, a fork 2 of each installation on two splined shafts 4, fork 2 is hinged with the flexible one end of electric pushrod 3, electric pushrod 3 other ends are hinged on 9, chassis.The controlled promotion fork 2 that synchronously elongates or shortens of electric pushrod 3 rotates, and fork 2 drives splined shaft 4 to rotate, and the lower swing arm 11 of installing on splined shaft 4 synchronously rotates, and the angle between upper and lower swing arm changes, and ride face 1 can raise thereupon, reduce variation.
On 1 upper two splined shaft 4 of ride face, two synchronous sheaves (sprocket wheel) 5 are installed respectively, synchronous sheave 5 takes the shape of the letter U, setting-in steel wire rope 6 in groove, steel wire rope 6 tightly installs around in two synchronous sheave 5 grooves and is ∞ font, steel wire rope 6 is fixed on to synchronous sheave 5 outsides with clamp 13, it is limit, the ∞ font left and right sides, its objective is in the time of 1 lifting of ride face, the right and left top link 12 synchronously carries out angle variation under lower swing arm 11 drives, (sprocket wheel and chain mounting means and synchronous sheave, steel wire rope identical) (shown in Fig. 2).
Two controlled elongations of electric pushrod 3 as shown in Figure 3, shorten length difference, two lower swing arm 11 rotational angles also change thereupon, lower swing arm 11 drives top link 12 to rotate, top link 12 rotates with top link splined shaft 4 and the sheave (sprocket wheel) 5 of synchronizeing thereupon, and ride face 1 changes and produces angle variation with upper and lower swing arm angle.
In the middle of practical application, can adopt single chip machine controlling circuit to realize to the control of two electric pushrods, on transfer car(buggy), be equipped with corresponding control panel, control knob and angle display lamp, owing to adopting existing control technology to realize, be therefore just not described in detail here simultaneously.
