An automatic compensation structure and compensation method for a synchronous hydraulic cylinder of an operating table

Abstract

The invention relates to an automatic compensation structure and method of synchronous hydraulic cylinders of an operating table or an operating bed. The automatic compensation structure is applicable to the operating table or the operating bed with longitudinal offset vertical columns, the operating table or the operating bed is provided with a group of synchronous hydraulic cylinders, a first piston and a second piston are arranged in the synchronous hydraulic cylinders respectively and divide the interiors of the synchronous hydraulic cylinders into a first cavity and a third cavity with the same section area, and the first cavity is communicated with the third cavity through a pipeline; a first one-way overflow valve and a second one-way overflow valve are arranged on a piston arranged between the first cavity and a second cavity of the synchronous hydraulic cylinders and on a piston arranged between the third cavity and a fourth cavity of the synchronous hydraulic cylinders respectively; the functions of the first one-way overflow valve and the second one-way overflow valve are preventing hydraulic oil in the second cavity from flowing to the first cavity and preventing hydraulic oil in the third cavity from flowing to the fourth cavity, and enabling the hydraulic oil in the first cavity to flow to the second cavity and the hydraulic oil in the fourth cavity to flow to the third cavity under the set opening pressure of the over-way overflow valves. The automatic compensation structure and method put forward the brand new automatic compensation principle of the synchronous hydraulic cylinders, and achieve automatic elimination of piston position difference by aid of the principle of hydraulic oil pressure difference.

Description

technical field [0001] The invention relates to a column longitudinally offset operating table, in particular to an automatic compensation structure and compensation method for synchronous hydraulic cylinders of the operating table. Background technique [0002] Column longitudinal offset operating table is one of the high-end operating tables currently on the market. It can meet the body position requirements that general non-column longitudinal offset operating tables cannot achieve. It is also convenient to realize the C-arm perspective of any part of the patient's body without occlusion. [0003] The column of the column longitudinally offset operating table is located below the back panel, the left and right hip panels 11, 12 or the left and right leg panels are suspended below, and the left and right hip panels 11, 12 and between the left and right leg panels No metal connection. The up and down movement of the left and right buttock plates or left and right leg plat...

Problems solved by technology

Due to the relatively professional manual compensation process, users cannot operate by themselves, causing maintenance personnel to come to repair and adjust for users repeatedly, resulting in high maintenance costs and poor user satisfaction.
