Embodiment 1
[0017] Such as figure 1 As shown, a support frame for manual height adjustment, the lift plate includes an upper lift plate 16 and a lower lift plate 1, and the support frame includes a symmetrically arranged oil storage tank 2 and a symmetrically arranged oil cylinder 13 for supporting the upper lift plate 16 , the support frame is located on the lower lifting plate 1, the oil cylinder 13 includes one or more independent cylinders, a starting device is arranged between the oil cylinders 13, and an oil inlet pipe 14 and an outlet pipe 14 are connected to the oil storage tank 2. Oil pipe 4, the oil cylinder 13 is connected to the oil storage tank 2 through the oil inlet pipe 14, the starting device is connected to the oil storage tank 2 through the oil outlet pipe 4, and the starting device is connected to the oil cylinder 13 through the oil pipe 8, the oil inlet pipe 14, the oil outlet pipe 4, The oil pipe 8 is respectively provided with a valve b15, a valve c3 and a valve d7....
Embodiment 2
[0020] As a special example of the first embodiment, the cylinder 13 in the first embodiment is provided with a cylinder a and a cylinder b, the cylinder a and the cylinder b are respectively provided with a piston a11 and a piston b12, and the cylinder a It communicates with cylinder b through valve a10.
[0021] In this embodiment, two cylinders are arranged in the oil cylinder 13. When the pressure in the oil cylinder 13 is increased, the cylinder a and the cylinder b increase the pressure at the same time, pushing the piston a11 and the piston b12 to move upward to play a supporting role. The function of a10, cylinder a and cylinder b are independent cylinders, and when a certain cylinder fails, the other cylinder can be guaranteed to continue to use.
Embodiment 3
[0023] In order to facilitate the control effect of the valve, the valve a10 described in the second embodiment is a rotary valve, so as to facilitate the control of the pressures in the piston a11 and the piston b12 to keep relatively independent.
