The utility model relates to a hydraulic control device used for the electric operation bed which solves the disadvantages that the gear transmission and the footstep hydraulic control manners used in the prior operation bed have poor reliability, and safety during the operation has hidden trouble. The hydraulic control device of the utility model is formed by connecting of a power source, an electromagnetic valve and a cylinder through the pipeline. Wherein, the power source is respectively connected with a left arm plate electromagnetic valve, a right arm plate electromagnetic valve and a motherboard electromagnetic valve. The left arm plate electromagnetic valve is respectively connected with a left and a right cylinder of the leg plate and the left and right lean cylinders. The right arm plate electromagnetic valve is respectively connected with the left and right cylinders of the motherboard and a front and back lean cylinders. The motherboard electromagnetic valve is connected with a lifting cylinder and a braking cylinder. The utility model realizes the action control for up and down, left and right, and front and back of the operation bed through the power source controlling the electromagnetic valve, the electromagnetic valve controlling the cylinder and the cylinder controlling the operation bed, thereby improving the action stability and safe reliability of the operation bed.
Description
One, technical field
This utility model relates to a kind of hydraulic control device, particularly relates to the hydraulic control device that a kind of operation table is used, and goes into A61G13/00.
Two, background technology
Its control mode of the operation table of domestic production at present is most of with gear drive and foot-operated hydraulic control method, this control method poor reliability, and the security presence in the operation hidden danger.Along with the continuous development of medical industry, pressed for advanced reliable high-grade operation table the equipment support successfully is provided for performing the operation.
Three, summary of the invention
The purpose of this utility model be to provide a kind of stable performance, action safe and reliable, can satisfy the novel operation bed hydraulic control device that electric operation bed control requires again.This electric operation bed is to carry out the oil circuit connection by power source, electromagnetic valve and oil cylinder by pipeline to form with hydraulic control device (hereinafter to be referred as hydraulic control device).Wherein power source connects with left arm plate electromagnetic valve, right arm plate electromagnetic valve, base plate electromagnetic valve respectively.And left arm plate electromagnetic valve respectively with lower limb plate left side oil cylinder, the right oil cylinder of lower limb plate and about the oil cylinder that inclines connect; Right arm plate electromagnetic valve connects with seat board left side oil cylinder, the right oil cylinder of seat board and anteversion and retroversion oil cylinder respectively; The base plate electromagnetic valve connects with hoist cylinder and brake oil cylinder.By the hydraulic control device that technique scheme is formed, can realize power source control electromagnetic valve, the solenoid control oil cylinder is about the oil cylinder control operation table, the left-right and front-back exercises of inclining.Above-mentioned so-called the connection refers to that all oil circuit connects, and the integrated electromagnetic valve that described electromagnetic valve is made up of two three position four-way electromagnetic valves, each electromagnetic valve are controlled two groups of actions respectively.Miniature hydraulic control one-way valve all is housed, so that the operating position of locked cylinder on oil cylinder.
The electric operation bed of forming according to technique scheme with hydraulic control device compared with prior art its advantage be: 1, two three position four-way electromagnetic valves are formed integrated electromagnetic valve, determine that each electromagnetic valve controls two groups of actions respectively, realize the control of integrated hydraulic system; 2, miniature hydraulic control one-way valve scientifically is combined on the oil cylinder, successfully finishes the setting of pressurize point, after satisfying power source and closing, the static position of operation table remains unchanged; 3, tandem two casing coupling oil cylinders in the hoist cylinder of operation table adopts guarantee that the operation table lifting is steady, and the operating angle oil cylinder of operation table adopts outer tandem, guarantees the synchronous even running of operation table bilateral oil cylinder.Hydraulic control device of the present invention has fundamentally solved the existing defective of existing operation table hydraulic control device, has improved the stability of electric operation bed, security reliability.
Four, description of drawings
Fig. 1, electric operation bed hydraulic control device structure principle chart.
Five, the specific embodiment
Below in conjunction with accompanying drawing, elaborate an embodiment of the present utility model.As shown in Figure 1: electric operation bed hydraulic control device is made up of power source, electromagnetic valve and oil cylinder.Wherein the R12 of power source 12 connects with the R11 of base plate electromagnetic valve 11, the R9 of left arm plate electromagnetic valve 9 and the R10 of right arm plate electromagnetic valve 10.The P12 of power source connects with the P11 of base plate electromagnetic valve, the P9 and the right arm plate electromagnetic valve P10 of left arm plate electromagnetic valve.21 of left arm plate electromagnetic valve 91 and lower limb plate left side oil cylinder 2 connects, and 92 of left arm plate electromagnetic valve connects with 12 of the right oil cylinder 1 of lower limb plate, and 22 of the left oil cylinder of lower limb plate connects with 11 of lower limb plate right side oil cylinder.101 of right arm plate electromagnetic valve 10 is connected with 51 of seat board left side oil cylinder 5,102 of right arm plate electromagnetic valve connects with 42 of the right oil cylinder 4 of seat board, 52 of seat board left side oil cylinder connects with 41 of seat board right side oil cylinder, 103 of right arm plate electromagnetic valve connects with 61 of anteversion and retroversion oil cylinder 6, and 104 of right arm plate electromagnetic valve is connected with 62 of anteversion and retroversion oil cylinder.111 of base plate electromagnetic valve 11 is connected with 71 of hoist cylinder 7.112 of base plate electromagnetic valve connects with 72 of hoist cylinder, and 113 of base plate electromagnetic valve connects with 81 of brake oil cylinder 8.Above-mentioned so-called the connection refers to that all oil circuit connects.When pressing electric operation bed that said structure forms and work with hydraulic control device at first power source switch on, after oil pressure is transferred to the operating pressure of requirement by the check valve in the power source through overflow valve, the left and right oil cylinder rise of lower limb plate is then controlled in electric magnet 91 energisings in left arm plate electromagnetic valve, the left and right oil cylinder of lower limb plate is return when 92 energisings, arbitrary position in oil cylinder rise and fall back process all can be by the hydraulically-controlled one-way valve locking of oil cylinder inside, the oil cylinder that inclines about when electric magnet 93 work rises, and the oil cylinder that inclines about during 94 energising work is return.The operation principle of right arm plate electromagnetic valve, base plate electromagnetic valve is identical with left arm plate electromagnetic valve.Generally speaking, be by the work of power source control electromagnetic valve, the work of solenoid control oil cylinder, the action of oil cylinder control operation table.
