Abstract
The utility model discloses a double-lifting point travel accurate-control device, and belongs to the technical field of hoists. The device comprises two sets of hydraulic pump stations which are the same and controlled by the same electric control system, wherein the electric control system comprises a PLC (programmable logic controller) and gate opening sensors; each hydraulic pump station comprises an oil cylinder, an adjustable-speed motor and an oil pump; the PLC controller is connected with the adjustable-speed motors through frequency converters; the adjustable-speed motors are connected with the oil pumps; the oil pumps are connected with the oil cylinders through oil delivery pipelines; the gate opening sensors are arranged on the oil cylinders, and are connected with the PLC; three-position four-way electromagnetic valves are arranged between the oil cylinders and the oil pumps. According to the double-lifting point travel accurate-control device, the PLC is used for simultaneously controlling the positions of the two oil cylinders in real time to realize double-lifting point travel accurate-control, so that the device is easy to operate, and can stably and reliably run; in addition, the device is simple in structure, easy to maintain and repair, suitable for popularization and application in production operation and high in practicability, and has good economic benefits.
Description
Technical field
The utility model belongs to headstock gear technical field, is specifically related to a kind of two suspension centre stroke precise control device.
Background technology
The operating principle of hydraulic gate hoist is the hydraulic oil with oil pump output high pressure, and by the road, hydraulic valve bank control enters piston-type hydraulic cylinder, driven plunger motion, by piston driving gate opening or close.Hydraulic gate hoist both can produce pulling force upwards, can produce again downward thrust, have advantages of operate steadily, control conveniently, hoisting capacity is large, size is little, lightweight, can simplify hydraulic architecture structure.Along with Hydraulic and Hydro-Power Engineering scale constantly to large-scale, super-huge development, many occasions, oneself becomes the irreplaceable unique selection of other machine hydraulic gate hoist scheme, is the ideal equipment that regulating gate opens and closes.But the Stroke Control equipment imperfection of headstock gear, cannot realize accurate control.
Utility model content
Goal of the invention: the purpose of this utility model is to provide a kind of two suspension centre stroke precise control devices, can not only accurately control the stroke of two hanging point hydraulic headstock gears, and operates steadily, reliably.
Technical scheme: for realizing above-mentioned utility model object, the technical solution adopted in the utility model is:
A kind of two suspension centre stroke precise control device, comprises the identical hydraulic power unit of two covers by same electrical control system control; Described electrical control system comprises PLC controller and gatage sensor; Described hydraulic power unit comprises oil cylinder, buncher and oil pump, and PLC controller is connected with buncher by frequency converter, and buncher is connected with oil pump; Described oil pump is connected with oil cylinder by pipeline road, and gatage sensor setting is on oil cylinder, and gatage sensor is connected with PLC controller; Between described oil cylinder and oil pump, be provided with three position four-way electromagnetic valve.
Described hydraulic power unit also comprises fuel tank, strainer, overflow valve and pressure meter.
Beneficial effect: compared with prior art, of the present utility model pair of suspension centre stroke precise control device, by PLC controller, control in real time the position of two oil cylinders simultaneously, realize two suspension centre strokes and accurately control, not only simple to operate, and operate steadily, reliably, this apparatus structure is simple simultaneously, is easy to maintenance and safeguards, has good economic benefit, suitable produce running in apply, there is good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of two suspension centre stroke precise control devices.
the specific embodiment,
Below in conjunction with accompanying drawing, technical solutions of the utility model are described, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, two suspension centre stroke precise control devices, comprise two cover hydraulic power units and a set of electrical control system, and electrical control system comprises PLC controller 1 and symmetrically arranged gatage sensor 3; Hydraulic power unit is symmetricly set on the both sides of PLC controller 1, and hydraulic power unit comprises oil pump 7 and buncher 6, and buncher 6 is connected with PLC controller 1 by frequency converter 2; Oil pump 7 is connected with oil cylinder 4 by pipeline road, and gatage sensor 3 is arranged on oil cylinder 4, and gatage sensor 3 is connected with PLC controller 1; By frequency converter 2, control the flow that the speed of buncher 6 regulates oil pump 7 to export, by flow-control, realize speed lifting and the height of oil cylinder 4 and steadily regulate; Between oil cylinder 4 and oil pump 7, be provided with three position four-way electromagnetic valve 5; Hydraulic power unit also comprises fuel tank, strainer, overflow valve and pressure meter,
The course of work: PLC controller is as Data Control Center, by the speed of the buncher on symmetrically arranged transducer drive oil pump, regulate the flow of oil pump output how many, make the oil cylinder of both sides synchronously reach lifting stably, three position four-way electromagnetic valve is directly controlled the lifting of oil cylinder and closes as executive component, and sensor is detecting oil cylinder position feedback as the signal source moment reaches the stop place of fixing two oil cylinders to PLC controller.
This pair of suspension centre stroke precise control device, by PLC controller, control in real time the position of two side cylinders, accurately control the stroke of headstock gear, not only simple to operate, and operate steadily, reliably, this apparatus structure is simple simultaneously, be easy to maintenance and safeguard, there is good economic benefit, suitable produce running in apply, there is good practicality.
Claims (2)
