The specific embodiment
For content of the present invention is become apparent more,, the present invention is described in further detail below in conjunction with drawings and Examples.
In conjunction with Fig. 1, hydraulic lift of the present invention comprises lifting table 4, with lifting table 4 bonded assembly jacking systems, be located at the base 1 under the jacking system, and the control jacking system rises or the controller of decline, jacking system comprises the electric hydaulic cylinder 3 that is fixed on the base 1, and electric hydaulic cylinder 3 connects controller by solenoid directional control valve, and the piston rod of electric hydaulic cylinder 3 connects lifting table 4; Jacking system also comprises guide piece, guide piece comprises the guidepost 2 that is fixed on the base, with the orienting sleeve 5 that is fixed on the lifting table 4, orienting sleeve 5 cooperatively interacts with guidepost 2, orienting sleeve 5 only can be moved, to guarantee the smooth running in lifting table 4 lifting process on the length direction of guidepost 2; Base 1 is provided with scale bar 6, by bolt sensor 7 is arranged on the scale bar 6, and sensor 7 signals can be passed in the controller.
In conjunction with shown in Figure 2, hydraulic lift of the present invention, its controller comprises CPU module and the D/A converter module that links to each other with the CPU module, analog-to-digital conversion module, memory module, load module and display module, analog-to-digital conversion module receives the position signal of the lifting table that transmits from sensor, signal is passed to the CPU module handles, and the demonstration of control data and storage.
In conjunction with Fig. 2, shown in Figure 3, the CPU module is a core with 51 micro controller systems in the controller of hydraulic lift of the present invention, CPU produces the drive signal of control lifting after analogue to digital conversion and filtering according to the parameter and the sensor signal result of load module input, amplify by power amplifier, drive solenoid directional control valve through half wave rectification again, to drive the action of jacking system control lifting table, when starting, the electric hydaulic cylinder can drive lifting table with certain speed rising or drop to corresponding height.Sensor feeds back to the displacement signal of lifting table in real time and carries out the AD sampling in the controller, hydraulic elevating platform is regulated again, and has realized closed loop control, makes lifting table can carry out lifting steadily, accurately.
