The utility model discloses simple structure can guarantee two pneumatic cylinder synchronous workings in the vertical direction, easily control.
Description
Technical field
The utility model relates to mechanical electronic hydraulic field, is specifically related to hydraulic cylinder synchronous system.
Background technique
Hydraulic transmission is applied increasingly extensive in modern mechanical transmission, and fluid pressure drive device has that structure is simple, volume is little, quality is light, can transmit huge power or high torque, is easy to realize the advantages such as overload protection.Hydraulicdriven device is often huger, complex structure, and force bearing point is many, and depend merely on an oil hydraulic cylinder and can not meet usage requirement, frequent multiple oil hydraulic cylinder uses simultaneously.The lifting of the pans of the intermediate tundish carriage of such as caster, just have employed at least plural oil hydraulic cylinder.This poses a problem: how to ensure multiple hydraulic cylinder synchronous work, to guarantee the normal performance of functions of the equipments.The wheel synchronization type of mechanical transmission oil hydraulic cylinder is broadly divided into following two kinds: 1) Mechanical course is synchronous; Shortcoming is that the guiding element of equipment and movement parts will have enough rigidity, intensity and accuracy of manufacturing, and therefore equipment is huger, less employing in actual production process.2) object of hydraulic cylinder synchronous is reached by the control of hydraulic system to hydraulic medium.The control of this type is divided into again two classes: 1. volumetric void fraction hydraulic synchronous system; Its shortcoming is: to oil hydraulic cylinder accuracy of manufacturing require higher, do not allow oil hydraulic cylinder have in let out.2. flow control hydraulic synchronous system; Shortcoming is poor to the adaptive capacity of equipment unbalance loading, and require higher to hydraulic medium turbidity test, control system is more complicated, and cost is higher, and system is easily generated heat, and efficiency is not high.
Summary of the invention
In order to solve the problem, the utility model provides a kind of structure simple, can ensure two hydraulic cylinder synchronous work in vertical direction, is easy to the hydraulic cylinder synchronous system controlled.
The utility model hydraulic cylinder synchronous system, comprise oil hydraulic pump, described oil hydraulic pump is connected with a selector valve, described selector valve is connected with two oil hydraulic cylinders by the dynamo-electric diverter valve that drives, be respectively the first oil hydraulic cylinder and the second oil hydraulic cylinder, dynamo-electric driving in diverter valve is provided with a spool, and described electromechanics drives the movement of diverter valve spool can drive the first oil hydraulic cylinder and the second hydraulic cylinder works respectively.
Preferably, dynamo-electric driving on diverter valve is connected with an electro-mechanical drive unit, described electro-mechanical drive unit is connected with a level detection device.
Preferably, electro-mechanical drive unit is a motor, and described motor can move left and right by driving machine electric drive diverter valve spool.
Preferably, liquid in level detection device, liquid level is suspended with a float, and float can move left and right in level detection device, and the left and right inwall of described level detection device is respectively arranged with a proximity switch, and described proximity switch is all connected with motor.
The utility model structure is simple, can ensure two hydraulic cylinder synchronous work in vertical direction, is easy to control.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference character: 1-oil hydraulic pump, 2-selector valve, 3-electromechanics drives diverter valve, 4-electro-mechanical drive unit, 5-level detection device, 6-first oil hydraulic cylinder, 7-second oil hydraulic cylinder.
Embodiment
The utility model hydraulic cylinder synchronous system, comprise oil hydraulic pump 1, described oil hydraulic pump 1 is connected with a selector valve 2, described selector valve 2 is connected with two oil hydraulic cylinders by the dynamo-electric diverter valve 3 that drives, be respectively the first oil hydraulic cylinder 6 and the second oil hydraulic cylinder 7, dynamo-electric driving in diverter valve 3 is provided with a spool, and described electromechanics drives the movement of diverter valve 3 spool can drive the first oil hydraulic cylinder 6 and the second hydraulic cylinder works 7 respectively.Dynamo-electric driving on diverter valve 3 is connected with an electro-mechanical drive unit 4, described electro-mechanical drive unit 4 is connected with a level detection device 5.Electro-mechanical drive unit 4 is a motor, and described motor can move left and right by driving machine electric drive diverter valve 3 spool.Liquid in level detection device 5, liquid level is suspended with a float, and float can move left and right in level detection device 5, and the left and right inwall of described level detection device 5 is respectively arranged with a proximity switch, and described proximity switch is all connected with motor.
When oil hydraulic cylinder jacking, if the second oil hydraulic cylinder 7 stroke is large, then device inclined, the float being then fixed on the level detection device 5 on equipment is moved to the left, and the float of movement is detected rear Starter electric drive unit 4 by proximity switch, and the spool of pusher electric drive diverter valve 3 is moved to the left, then dynamo-electric driving diverter valve 3 left mouthfuls of increased flow capacity, the dynamo-electric right mouth of diverter valve 3 that drives then trends towards throttling, and therefore the first oil hydraulic cylinder 6 speed is accelerated, till two cylinders are synchronous; When oil hydraulic cylinder declines, if the second oil hydraulic cylinder 7 stroke is large, then device inclined, then the float of level detection device 5 moves right, and then electro-mechanical drive unit 4 starts, and the spool of pusher electric drive diverter valve 3 is moved to the left, then dynamo-electric driving diverter valve 3 left mouthfuls of increased flow capacity, right mouth then trends towards throttling, and therefore the first oil hydraulic cylinder 1 accelerates to decline, till two cylinders are synchronous.
