Abstract
The utility model discloses an electric-hydraulic control curtain screen. The curtain screen adopts the structure that a ball-shaped track is fixed on a ceiling; a single rod piston hydraulic cylinder is fixed at the left end of a stage and provided with a piston rod; a ball head track is arranged inside the piston rod; one end of a ball head rod is connected with the ball-shaped track and the other end is welded on the piston rod; and two ends of the curtain screen are respectively fixed at the right ends of the single rod piston hydraulic cylinder and the piston rod via a fixing hook A and a fixing hook B. An electromagnetic-hydraulic control system controls the rapid reversing of the piston rod inside the single rod piston hydraulic cylinder and makes full use of hydraulic transmission to drive the curtain screen to freely move via the piston rod; the rapid reversing and retraction of the curtain screen are realized via a three-position four-way electromagnetic directional valve; and the speed change-over and remote control of the curtain screen during movement are realized by the control of a two-position two-way electromagnetic directional valve. The curtain screen has the advantages of simple structure, convenient operation, high reliability and great popularization value, etc.
Description
Technical field:
The utility model relates to a kind of curtain control device, relates in particular to a kind of device that jointly controls curtain by electric liquid.
Background technology:
At present, the curtain folding and unfolding of each large-scale cinema is mostly by machinery or electric control, because curtain is not only greatly but also thick and heavy, and difficulty relatively when the problem of existence is governing speed, and curtain folding and unfolding commutation is insensitive, can influence the effect that spectators watch.
Summary of the invention:
The utility model provides a kind of device that jointly controls curtain by electric liquid at the deficiencies in the prior art.
Realize above purpose, the technical solution adopted in the utility model is as follows:
The curtain that a kind of electric liquid jointly controls, by spherical track, piston hydraulic cylinder of single rod, fixedly suspension hook A, fixedly suspension hook B, ball rod, piston rod, bulb track, movable hook, curtain, electromagnetic hydraulic pressure control system are formed; Spherical track is fixed on the ceiling, piston hydraulic cylinder of single rod is fixed on the stage left end, piston hydraulic cylinder of single rod is provided with piston rod, be provided with the bulb track in the piston rod, ball rod one end is connected with spherical track, the other end is welded on the piston rod, the curtain two ends respectively by fixing suspension hook A and fixedly suspension hook B be fixed on piston hydraulic cylinder of single rod and the piston rod right-hand member, piston rod commutates fast in the electromagnetic hydraulic pressure control system control piston hydraulic cylinder of single rod.
Described movable hook is installed in the bulb track, and piston rod drives curtain by piston rod and moves freely in flexible.
Described curtain is divided into left and right sides two parts, and this is described as the left half structure, left half structure and right half structural similarity.
Described electromagnetic hydraulic pressure control system is by fuel tank, hydraulic pump, overflow valve, electromagnet A, electromagnet B, the 3-position 4-way solenoid directional control valve, flow speed control valve A, flow speed control valve B, electromagnet C, the bi-bit bi-pass reversal valve is formed, wherein hydraulic pump communicates with fuel tank, divide the two-way pipeline to provide oil pressure through the 3-position 4-way solenoid directional control valve on the hydraulic pump external pipe for piston hydraulic cylinder of single rod, wherein be in series with flow speed control valve A and flow speed control valve B on one road pipeline, through being provided with the bi-bit bi-pass reversal valve simultaneously on the flowline after the flow speed control valve B speed governing, the hydraulic pump two ends have also connect an overflow valve, 3-position 4-way solenoid directional control valve both sides respectively are provided with electromagnet A and electromagnet B, and bi-bit bi-pass reversal valve one side is provided with electromagnet C.
The utility model makes full use of hydraulic drive, be provided with the bulb track in the piston rod, movable hook is installed in the bulb track, piston rod is in flexible, drive curtain by piston rod and move freely, realize commutation fast, realize the folding and unfolding of curtain by the solenoid directional control valve of 3-position 4-way, speed quick change when the control of the solenoid directional control valve by 2/2-way realizes that curtain moves connects, and realizes Long-distance Control.
