The indicator of opening of formula.
Utility model content
Technical problem to be solved in the utility model is：In order to solve under powering-off state it is impossible to know oil cylinder or gate
The problem of position, and also to solving some indicator of openings to install circumscribed problem, this utility model provides a kind of table
Disk shutter indicator of opening.
This utility model solves its technical problem technical scheme to be taken：A kind of dial type gatage instruction
Device, including scale dial plate, scroll spring, rope sheave, steel wire rope, reducing gear and shell, described scale dial plate is arranged on outside shell
The upper end in portion, and described scale dial plate is provided with the pointer circumferentially rotating, described scroll spring, rope sheave, leading screw and reducing gear
Install inside the housing, described steel wire rope one end is connected with the piston rod of gate or oil cylinder, and the other end is fixed on rope sheave, described
The rotating shaft of rope sheave is connected with the input shaft of reducing gear, and the input shaft of described reducing gear is with rope sheave synchronous axial system, described subtracts
The input shaft of fast mechanism is in transmission connection with the pointer of described scale dial plate, and described rope sheave is co-axially mounted with described scroll spring, when
When piston rod stretches out steel wire rope and is drawn out, rope sheave rotates makes described scroll spring roll tightly storage power, when piston rod bounces back, described whirlpool
Coil spring recovers to drive rope sheave rotation to make wirerope-winding on rope sheave.
Further, also include leading screw, the rotating shaft of described rope sheave is fixedly connected with leading screw one end, the described leading screw other end with subtract
The input of fast mechanism is fixedly connected.
Further, described scroll spring one end is fixedly connected with described shell, and the described scroll spring other end is solid with leading screw
Fixed connection.
Preferably, described reducing gear is gear reduction.
Further, described piston rod is provided with and hangs head, and described steel wire rope is fixedly connected with hanging head.
Further, also include the limit device of keying height and the rotary encoder for regulating gate or oil cylinder.
Operation principle：
Shell is mainly for the protection of scroll spring, rope sheave, leading screw, rustless steel steel wire rope and gear reduction, scrollwork bullet
The effect of spring is so that steel wire rope is retracted, and steel wire rope stretches out, and relies on what steel wire rope head was connected to gate or cylinder piston rod to hang head,
Stretch out power using piston rod and pull stretching out of steel wire rope；When steel wire rope stretches out, drive rope sheave to rotate, pass sequentially through leading screw and subtract
Fast mechanism indicates corresponding position by pointer the rotational angle of rope sheave on scale dial plate.
Steel wire rope is connected with the head that hangs of gate or cylinder piston rod, and when piston rod is in upper end, wirerope-winding exists
On rope sheave；When piston rod stretches out, steel wire rope moves with piston rod and is drawn out, and drives rope sheave, leading screw rotation, simultaneously same with rope sheave
The scroll spring that axle is installed is rolled tightly and stores power；When piston rod bounces back, rely on the storage power of spring to drive rope sheave to rotate, and make steel
Cord is in tensioning state all the time and smoothly reclaims on rope sheave.
Described gear reduction is fixedly connected with leading screw, and leading screw is fixedly connected with rope sheave, scroll spring again.Therefore exist
During steel wire rope extends and retracts, gear reduction can rotate according to the linear motion of steel wire rope, thus driving dial plate
On indicators turn, indicate corresponding position.
The beneficial effects of the utility model are：A kind of dial type gatage indicator that this utility model provides, strengthens
The motility installed and polytropy, improve intuitive and the reliability of display, and easy and simple to handle, easy to implement.
