Description

Steam turbine repairs Special universal spanner
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:
Embodiment 1:
A kind of steam turbine maintenance Special universal spanner, composition includes: hollow insertion tube 1 and spanner lantern ring 2, the spanner set Be welded and fixed on the wherein annular surface in outside of ring with one end of bolt A3, the other end of the bolt A with it is described hollow The top planes of insertion tube are welded and fixed, and plane and the bolt B 4 of the bottom of the hollow insertion tube are welded and fixed, wherein described Circular hole 5, the bolt A, the bolt B, the circle are offered on the connection picture of hollow insertion tube and the bolt A Inserted with threaded rod 6 is adjusted in hole and the hollow insertion tube, the bottom of the adjusting threaded rod is vertically welded with adjusting spiral shell Bolt 7.
Embodiment 2:
Special universal spanner, vertical welding on the cylinder face of the hollow insertion tube are repaired according to steam turbine described in embodiment 1 There is hollow collet head 8,9 structure of hexagon slot is processed into the inside of the cannulated sleeve head.
Embodiment 3:
The steam turbine according to embodiment 1 or 2 repairs Special universal spanner, on the ring-like face in inside of the spanner lantern ring It is welded with the screw die 10 of laciniation, the screw die is vertical with the adjusting screw rod, the adjusting screw rod and described Hollow insertion tube be parallel construction.
Embodiment 4:
