Description
Technical field:
The utility model relates to a kind of steam turbines to repair Special universal spanner.
Background technique:
When repairing to steam turbine, spanner is common maintenance tool in maintenance process, and existing functions of wrench compares
It is single, when maintenance, a variety of various sizes of U-shaped head spanners is needed to be replaced, to disassemble and install instrument, and uses Flexible spanner
Hand, heavier-weight, volume is larger, inconvenient to carry, and the head of spanner two sides is thicker, while monkey wrench also frequently occurs
Adjusting screw rod there is a phenomenon where clamping stagnations, influence maintenance efficiency.Meanwhile needs often can be also encountered when repairing to steam turbine and are dismantled
Status it is very narrow or recess very deep bolt or nut when, with common spanner, torn open around position needing to dismantle
It dismantles, not only increases intensity of workers, but also instrument is easy to cause to be damaged.
Summary of the invention:
The purpose of the utility model is to provide a kind of steam turbines to repair Special universal spanner.
Above-mentioned purpose is realized by following technical scheme:
A kind of steam turbine maintenance Special universal spanner, composition includes: hollow insertion tube and spanner lantern ring, the spanner lantern ring
The wherein annular surface in outside on be welded and fixed with one end of bolt A, the other end of the bolt A and the hollow insertion tube
Top planes be welded and fixed, the plane of the bottom of the hollow insertion tube is welded and fixed with bolt B, hollow inserts wherein described
Cylinder with offer circular hole, the bolt A, the bolt B, the circular hole and institute on the connection picture of the bolt A
Inserted with threaded rod is adjusted in the hollow insertion tube stated, the bottom of the adjusting threaded rod is vertically welded with adjusting bolt.
The steam turbine repairs Special universal spanner, is vertically welded with cannulated sleeve on the cylinder face of the hollow insertion tube
It is processed into hexagon inserting slot construction in the inside of head, the cannulated sleeve head.
The steam turbine repairs Special universal spanner, is welded with zigzag knot on the ring-like face in inside of the spanner lantern ring
The screw die of structure, the screw die is vertical with the adjusting screw rod, and the adjusting screw rod is parallel with the hollow insertion tube
Structure.
The steam turbine repairs Special universal spanner, and the bolt A and the bolt B are parallel construction, and described
Bolt A it is identical with the diameter of the bolt B.
The utility model has the beneficial effects that
1. hex nut, hex bolts, round tube that the utility model will will be dismantled or be installed on steam turbine when in use
Or square tube is arranged between screw die and the end for adjusting threaded rod, is then rotated with hand and adjusts bolt, adjusts bolt drive and adjusts
Threaded rod rotation, makes the end for adjusting threaded rod withstand the hex nut or hex bolts to be dismantled, then rotates hollow insert
Cylinder, hollow insertion tube band wrench lantern ring rotate, by steam turbine hex nut or hex bolts remove, or can hold hollow
The cylinder face of cannulated sleeve head in insertion tube rotates, and when hex nut or hex bolts can be prevented to be close to steam turbine shell, pulls
There is a situation where slip between gloves ring and hex nut or hex bolts.
The utility model is provided with cannulated sleeve head in hollow insertion tube, for installing or removing hex bolts or hexagonal spiral shell
Mother, it is simple and reasonable, it is easy to use, when repairing steam turbine, when need to dismantle space it is very narrow or recess very deep spiral shell
When bolt or nut, directly cannulated sleeve head is probeed into, it is not necessary to be disassembled around space needing to dismantle.Make hollow insertion tube
T-type design is formed between collet head, the arm of force, which increases, to be easy firmly, both to reduce intensity of workers, also avoid vapour
Machine is damaged.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the left view of attached drawing 1.
In figure: 1, hollow insertion tube, 2, spanner lantern ring, 3, bolt A, 4, bolt B, 5, circular hole, 6, adjusting threaded rod, 7, adjusting
Bolt, 8, cannulated sleeve head, 9, hexagon slot, 10, screw die.
Specific embodiment:
