Embodiment 1
As shown in figures 2-3, the present embodiment provides a kind of separate type headstock gear, which is mounted on the fast open-blind of ring locking-type
On hardened structure, subdivision ring 1 is mounted on blind plate hubbed flange 9 (flange 9 at pressure vessel inlet and outlet position is arranged in) and door closure
Between 10, subdivision ring 1 is connected by connecting rod 8 with push-pull mechanism, power of the push-pull mechanism by rotating mechanism, drives subdivision ring
1 movement is to realize enabling and door closing procedure.
As shown in figure 4, being provided with dragging track 4 i.e. thrust slot on turntable 3, thrust slot is along turntable 3 weeks in the present embodiment
To equally distributed arc thrust slot, arc thrust slot is impeller shape, i.e. arc thrust slot and turntable 3 be not coaxial, arc thrust
The both ends of slot are located at the different-diameter position of turntable 3；Rotation armed lever 11 passes through through-hole 12 and can be used cooperatively with rotary arm shaft 2,
By rotation rotation armed lever 11 make rotary arm shaft 2 rotate, since rotary arm shaft 2 is connected with turntable 3, then can push turntable 3 around
It is axially rotated, and the thrust that turntable 3 is subject to passes to thrust idler wheel 5, so that guide roller 7 be made to move in the sliding slot 15 of door closure 10
It is dynamic, and then connecting rod 8 is driven to be moved back and forth, so that the subdivision ring 1 being connected with connecting rod 8 radially moves back and forth disengaging method
In the link slot of orchid 9, reach the opening and closing of subdivision ring 1, to realize enabling and door closing procedure.Guide roller 7 can reduce friction
Resistance.
Thrust idler wheel 5 and guide roller 7 are passed through into pin 6, pin 6 is inserted into dragging track 4 later, so that thrust idler wheel
5 are put into dragging track 4；Finally fixing screws 14 are passed through from turntable 3, so that fixing screws 14 and 3 clearance fit of turntable, turn
Disk 3 can independently rotate, and fixing screws 14 realize the axially position to turntable 3 simultaneously.
In opening-closing process, can reserve between subdivision ring 1 and the link slot of flange 9 can centainly pass in and out gap, and the gap is by having
There is the sealing ring 13 of float function to realize.Sealing ring 13 is located in the fluting of 10 bottom of door closure.Sealing ring 13 is initially installed
Position with the presence of the certain floating spacing in internal pressure operating position, it is possible thereby to after operating pressure is laid down, allow sealing ring 13 on the door
There is no pressure effects for lid 10 and lock ring, guarantee the no drag effects of opening and closing locked to ring.The push-pull effort of subdivision ring 1 as a result,
It only needs mainly to overcome based on weight (subdivision ring and strut weight) and the frictional resistance as caused by weight, the rotation arm strength of turntable 3
(torque) is as long as overcome the resistive torque；It can not disappear since the resistance influences to compare on lock ring opening and closing since sealing ring is held out against
The uncertain drag effects removed and generated are lesser, thus are considerably increased using the controllable large-scale and high pressure of manual wrench
Act on the size range of door closure opening and closing.
Embodiment 2:
As shown in figure 3, being with the difference of above-described embodiment 1, rotary arm shaft 2 and 6 central axis weight of pin in the present embodiment
It closes, keeps capable transmission efficiency higher.
A kind of separate type headstock gear provided by the present application, rotating mechanism and push-pull mechanism cooperate, and correspond to one
Subdivision ring realizes the independent control to subdivision ring, and structure is simple, is easy to control, easy to operate.Meanwhile it being opened and closed in separate type single
Interlocking gear is set between member, so that each separate type opening and closing unit is opened or carried out one by one in order when being closed, avoids position
Point is omitted.
Although the application is described above by referring to specific embodiment, one of ordinary skill in the art are answered
Work as understanding, in principle disclosed in the present application and range, many modifications can be made for configuration disclosed in the present application and details.
The protection scope of the application is determined by the attached claims, and claim is intended to technical characteristic in claim
Equivalent literal meaning or range whole modifications for being included.
