In the present embodiment, described multiple idle pulley 6 is arranged on erecting frame about 1 both sides, described bottom and top idle pulley adapter plate 18 is following.
In the present embodiment, described top supporting frame 7, described first side pillar stiffener 3, described second side pillar stiffener 11 and described bottom erecting frame 1 at right angle setting, it is following that the lazy adapter plate in described top 18 is placed in described top supporting frame 7, describedly fixedly lead 8 and be arranged on described first side pillar stiffener 3 respectively with on described second side pillar stiffener 11 with described roller track 5, the side of described pulley 10 is connected with described fixed guide 5, opposite side is fixed on load mounting table 9, described roller 4 is contacted with described roller track 5 and is fixed on described load mounting table 9 by described setting device 15.
Incorporated by reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, Figure 2 shows that the enlarged drawing of I part in Fig. 1, Figure 2 shows that the lateral plan of jacking system in an embodiment of the present invention, Figure 3 shows that bottom drive configuration sketch in an embodiment of the present invention.
In the present embodiment, setting device 15 is made up of spring 16, spring shaft (not shown) and nut (not shown), automatically can adjust the play between roller 4 and roller track 5.
In the present embodiment, the number of idle pulley 6 is 12, and wherein 8 idle pulleys 6 are arranged on erecting frame about 1 both sides, described bottom, and 4 idle pulleys are installed on top idle pulley adapter plate 18.
In the present embodiment, jacking system also comprises Timing Belt actuating device and lifting Timing Belt 2.
In the present embodiment, Timing Belt actuating device comprises: drive motor 21, belt wheel coupling rod 20, motor synchronous belt 19, tension wheel 17, lifting synchronous pulley 14, drive motor output wheel 13 and axle connecting rod belt wheel 12.
In the present embodiment, described drive motor 21, described tension wheel 17, described lifting synchronous pulley 14, described drive motor output wheel 13 and described axle connecting rod belt wheel 12 are arranged on described bottom erecting frame 1 time.
In the present embodiment, described drive motor 21 is connected with described drive motor output wheel 13, and described drive motor output wheel 13 is connected by described motor synchronous belt 19 with described axle connecting rod belt wheel 12.
Described lifting synchronous pulley 14 is coaxially installed by belt wheel coupling rod 20 with described axle connecting rod belt wheel 12.In the present embodiment, lifting synchronous pulley 14, lifting Timing Belt 2 are respectively two, and lifting synchronous pulley 14 is flexibly connected with load mounting table 9 by lifting Timing Belt 2.
In the present embodiment, described drive motor 21 drives described drive motor output wheel 13 to rotate, and then drive described motor synchronous belt 19, described axle connecting rod belt wheel 12 rotates together with described belt wheel pitman shaft 20, thus drive described lifting Timing Belt 2 to move, described lifting Timing Belt 2 moves and drives described load mounting table 9 to move up and down on described fixed guide 8, thus realizes the lifting transmission of carrier.
