The utility model discloses a hydraulic hoist for an upturned gate; it comprises a hydraulic actuator composed of an oil cylinder, a piston and a piston rod, and a hinge seat hinged at the hanging head of the oil cylinder; The upper end cover of the oil cylinder is provided with a magnetostrictive displacement sensor, the measuring magnetic ring of the magnetostrictive displacement sensor is fixedly set on the piston rod, and the measuring magnetic rod of the magnetostrictive displacement sensor extends to the central measuring hole of the piston rod; An inductive proximity switch is arranged on the outer peripheral surface of the hanging head on the oil cylinder, and an induction bracket for inducting the inductive proximity switch is arranged on the hinge seat; a bypass pipeline is opened on the main oil circuit of the rod cavity of the oil cylinder, so The above-mentioned bypass pipeline communicates with the oil tank through the electromagnetic reversing valve. The utility model has the advantage that the expansion and contraction of the piston rod and the rotation angle of the upper head of the oil cylinder can be accurately controlled during the opening and closing operation of the hydraulic hoist. So as to ensure the safe, reliable and smooth operation of the gate.
Description
Technical field
The utility model relates to hydraulic hoist, especially relates to the hydraulic hoist that is used for upward turnover type gate.
Background technique
Along with the progress in development of science and technology and epoch, Small Watershed Management project that urban ecology water system, new countryside construction are carried out and the hydraulic engineering of ecologically clean type are more and more.Urban ecology water system and middle and small river administer that engineering has that head is low, river surface arrange clean and tidy, coordinate, satisfy characteristics such as places of cultural interest requirement mutually with urban environment.This just makes that the gate span of arranging according to above condition is very big, and also will possess navigation condition behind a lot of gate opening.Therefore, upward turnover type gate arises at the historic moment.Upward turnover type gate generally will be finished by many hoist simultaneously operatings in to the opening-closing process of gate, because the inhomogeneous and leakage rate property of there are differences of machining accuracy, surface friction drag, load of each hoist oil cylinder causes each oil cylinder will produce synchronism deviation when operation.Therefore the flexible stroke accuracy of hoist piston rod, synchronization accuracy etc. are had relatively high expectations, otherwise will cause the torsional deformation of gate and damage.
The model utility content
The hydraulic hoist that is used for upward turnover type gate that provides a kind of control accuracy high is provided the utility model purpose.
For achieving the above object, the utility model can be taked following technical proposals:
The hydraulic hoist that is used for upward turnover type gate described in the utility model; It comprises the hydraulic actuator that oil cylinder, piston, piston rod constitute and is articulated in a free bearing at described oil cylinder upper hoisting head place; Upper end cap at described oil cylinder is provided with magnetostrictive displacement sensor, and the measurement magnet ring of described magnetostrictive displacement sensor is fixedly set on the described piston rod, and the measurement bar magnet of magnetostrictive displacement sensor extends in the measuring hole of piston rod center; Oil cylinder upper hoisting head outer circumferential face is provided with inductance approach switch, and described free bearing is provided with the induction support that is used to respond to described inductance approach switch; Offer bypass duct on the cylinder rod chamber working connection, described bypass duct is connected with fuel tank by solenoid directional control valve.
The utility model advantage just is to be arranged on the built-in magnetostrictive displacement sensor at described oil cylinder upper end cap place and is arranged on inductance approach switch on the oil cylinder upper hoisting head outer circumferential face; Therefore, extending amount, the oil cylinder upper hoisting head corner amount of piston rod is able to accurate control in the hydraulic hoist keying running.Offer bypass on the cylinder rod chamber working connection, described bypass is connected with fuel tank by solenoid directional control valve; Adopt many hydraulic hoists that same gate is opened and closed the operating cyloinder operation when deviation occurring like this, according to the described electromagnetic switch valve events of deviation signal, the oil cylinder bypass draining of going ahead of the rest reaches the purpose of adjustment multi-cylinder speed unanimity to fuel tank; When the deviation of many each oil cylinders of hydraulic hoist reached the scope of setting permitted value, the solenoid directional control valve dead electricity resetted, and stops draining.PLC is by comparing in real time many oil cylinder stroke measuring systems → feedback signal → send instruction, solenoid directional control valve continuous, dead electricity adjusts the motion speed of a plurality of oil cylinders, until synchronously.Thereby guarantee gate safety, reliable, smooth running.
