Detailed ways

Below in conjunction with accompanying drawing and embodiment the technical scheme of the present utility model is further described:

As shown in Figure 1, the hydraulically driven elevator device of the present invention includes an elevator car 3, a battery 4, a movable floor 5 and a hydraulic buffer 6, the elevator car 3 is hoisted in the elevator shaft 2 by a cable 1, and the battery 4 is installed in the elevator shaft. The top of the cabin 3 provides power for the hydraulic buffer 6, which is installed on the bottom plate of the elevator car 3, and a movable bottom plate 5 is installed above the hydraulic buffer 6, and the hydraulic buffer 6 generates hydraulic pressure through the internal oil body. To control the up and down movement of the movable base plate 5, so that the movable base plate 5 produces upward or downward acceleration.

As shown in Figure 2, the hydraulic buffer 6 includes a piston 7, a buffer column 8, an induction hydraulic pump 9, an induction reversing valve 10, and an oil cylinder 11. The oil cylinder 11 is provided with a cylinder head 12, an buffer column 8, an induction hydraulic pump 9 and an oil cylinder 11 are installed on the bottom plate of the elevator car 3, the piston 7 is installed in the buffer column 8, the top of the piston 7 is fixedly connected with the movable bottom plate 5, the oil inlet and outlet of the buffer column 8 pass through the induction reversing valve 10 and the induction hydraulic pump 9 It is connected with the oil cylinder 11, and the induction hydraulic pump 9 is connected with the oil cylinder 11. The induction reversing valve 10 and the induction hydraulic pump 9 can simultaneously control the switch action through the induction of acceleration.

The top of the induction reversing valve 10 is connected with a magnetic rod 13, which can attract the magnetic sheet 15 above it, and the magnetic sheet 15 is installed on the fixed plate connecting the buffer column 8 and the oil cylinder 11, and the induction reversing The bottom of the valve 10 is connected to the spring 14, and the other end of the spring 14 is connected to the casing of the induction hydraulic pump 9.
