Abstract
This utility model provides a kind of adjustment every bar trip-proof device, including being enclosed within the T-shaped set handled in seat sliding sleeve.Being cased with door rod in described T-shaped set, the bottom of described door rod is by fixing with sidepiece bottom T-shaped set, and the top of described door rod first passes through the concave surface pad being enclosed within door rod and fixes, then by being enclosed within the top of door rod and being positioned at the locking nut locking above concave surface pad.Between described manipulation seat sliding sleeve top and concave surface pad, clamping has the top ball ring being enclosed within outside T-shaped set, and clamping bottom described manipulation seat sliding sleeve and between T-shaped set bottom has the lower spherical pad being enclosed within outside T-shaped set.The side of described locking nut is provided with and the boss of locking nut one, described boss laterally has a groove, described boss vertically has a through hole, is installed with a regulation bolt in described through hole.The advantage of this patent is, when door rod occurs to loosen, can constantly reduce the width of groove by rotating regulation bolt, so that locking nut diameter diminishes, and then door rod be clamped, and this patent overall structure is simple and reliable, designs ingenious.
Description
Technical field
This utility model relates to a kind of door rod fixing device, a kind of for adjusting the anti-tripping of every bar
Device.
Background technology
Regulation every bar of steam turbine is by T-shaped set, lower spherical pad, top ball ring, concave surface pad and special
The pressuring action of locknut is connected to an entirety with handling seat sliding sleeve.If one of them part dimension is improper,
As top or lower spherical pad is the thinnest, concave surface pad groove set the deepest or the most shallow, T-shaped and door rod without clamp force etc.,
Door rod top will be made to connect and handle seat sliding sleeve and produce and loosen, cause adjusting every bar in open and close process or
In properly functioning, owing to steam flow blows adjustment family of power and influence's door, and produce upper and lower beating, not only affect unit load
Stablize, also can make to produce at door rod screw thread and the special locknut of door rod alternate stress, of long duration, door rod silk
Button and locknut screw thread will wear and tear, loosen, and causes door rod locknut to come off, affects unit properly functioning.
It addition, door rod locknut clamp force is inadequate, the special locknut of former door rod is inadequate with door rod screw thread clamp force, door rod with
After locknut coordinates operation a period of time, it coordinates clamp force to reduce, and adjusts lifting force when door is opened the biggest so that door
Lever lock mother threads off, and is also common reason.
Utility model content
For solving the problems referred to above, this utility model provides adjustment every bar of a kind of adjustable gripping dynamics to be prevented
Trip gear.
Realize adjustment every bar trip-proof device of this utility model purpose, including being enclosed within manipulation seat sliding sleeve
T-shaped set, is cased with door rod in described T-shaped set, the bottom of described door rod by bottom T-shaped set and sidepiece fix,
The top of described door rod first passes through the concave surface pad being enclosed within door rod and fixes, then by being enclosed within top and the position of door rod
Locking nut locking above concave surface pad.
Between described manipulation seat sliding sleeve top and concave surface pad, clamping has the top ball ring being enclosed within outside T-shaped set,
Clamp bottom described manipulation seat sliding sleeve and between T-shaped set bottom and have the lower spherical pad being enclosed within outside T-shaped set.
The side of described locking nut is provided with and the boss of locking nut one, and described boss laterally has
Article one, groove, described boss vertically has a through hole, is installed with a regulation bolt in described through hole.
A kind of steam turbine described in this patent adjusts every bar trip-proof device, when the steam turbine mistake duration of runs
Long, when door rod occurs to loosen, can constantly reduce the width of groove by rotating regulation bolt, so that lock
Jack panel diameter diminishes, and then door rod is clamped.
This patent overall structure is simple and reliable, designs ingenious, can carry out upgrading on the original basis, whole
Body manufacturing cost is the highest, and beneficially large-scale promotion uses.
Accompanying drawing explanation
Fig. 1 is the structural representation that steam turbine of the present utility model adjusts every bar trip-proof device.
Fig. 2 is the structural representation of locking nut.
Detailed description of the invention
As depicted in figs. 1 and 2, adjustment every bar trip-proof device of the present utility model, including being enclosed within manipulation
T-shaped set 2 in seat sliding sleeve, is cased with door rod 1 in described T-shaped set 2, T is passed through in the bottom of described door rod 1
Fix with sidepiece bottom jacket 2.
The top of described door rod 1 first passes through the concave surface pad 6 being enclosed within door rod 1 and fixes, then by being enclosed within door rod
The top of 1 and be positioned at the locking nut 7 above concave surface pad 6 and lock.
Between described manipulation seat sliding sleeve 4 top and concave surface pad 6, clamping has the upper ball being enclosed within outside T-shaped set 2
Face pad 5, clamps bottom described manipulation seat sliding sleeve 4 and between T-shaped set 2 bottom and is enclosed within outside T-shaped set 2
Lower spherical pad 3.
The side of described locking nut 7 is provided with and the boss 12 of locking nut 7 one, described boss 12
On laterally have a groove 15, described boss 12 vertically has a through hole 14, described through hole 14
Inside it is installed with a regulation bolt 13.
A kind of steam turbine described in this patent adjusts every bar trip-proof device, when the steam turbine mistake duration of runs
Long, when door rod 1 occurs to loosen, can constantly reduce the width of groove 15 by rotating regulation bolt 13,
So that locking nut 7 diameter diminishes, and then door rod 1 is clamped.
Embodiment described above is only to be described preferred implementation of the present utility model, the most right
Scope of the present utility model is defined, and without departing under this utility model design spirit premise, this area is general
Lead to various deformation and improvement that technical solutions of the utility model are made by engineers and technicians, this reality all should be fallen into
In the protection domain determined with novel claims.
