The fastening threaded rod is sleeved with a main pressure plate and an auxiliary pressure plate, wherein the main pressure plate and the auxiliary pressure plate are tightly attached to the two side end faces of the coupling. The position, on the outer side of the main pressure plate, of the fastening threaded rod is connected with a fastening nut. The position, on the outer side of the auxiliary pressure plate, of the fastening threaded rod is sleeved with a fastening sleeve. The fastening sleeve is provided with a radial locking screw. The main pressure plate is connected with an L-shaped indicator frame. A dial indicator is arranged at the tail end of the top of the indicator frame. The coupling alignment device has the advantages of being simple in structure, convenient to machine and manufacture and low in cost; centering and alignment can be performed conveniently and quickly in a time and labor saving mode; the indicator frame does not need to be disassembled, assembled and adjusted repeatedly, and measured data are accurate. Besides, the L-shaped adjustable indicator rod structure is adopted to adapt to various couplings at different heights.
Description
Technical field
The utility model relates to a kind of junction box levelling device.
Background technique
The key technical indexes after steam turbine power generation is unit vibration, and unit vibration is large, and potential safety hazard is more, when serious, cannot start shooting, and more serious may cause runaway accident.The way that reduces unit vibration is all found by domestic each genco and electricity Jian unit.
The direct factor that affects unit vibration be coupling wooden dipper partially and circumference data, conventionally while measuring circumference data, first dial framework is fixed on " A " coupling, dial gauge contact is on " B " coupling, moving two rotors of dish are measured data, adjust according to centering according to number.After adjustment finishes, dial gauge is removed.Reinstall while adjustment next time.Due to turbine body installation procedure complexity, junction box levelling work needs repeated measurement and adjustment, will dismantle repeatedly and adjust like this dial framework, and not only efficiency is low, also expends a large amount of manpowers.Different set coupling spacing differences in addition, when spacing is too large, dial gauge cannot set up, and that sets up reluctantly is also oversize because of distance, affects data measured precision.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of junction box levelling device convenient to use.
The utility model is realized by following measures:
A kind of junction box levelling device of the present utility model, comprise the fastening screw that runs through coupling center hole, on described fastening screw, cover has main pressure plate and the auxiliary platen of being close to coupling both sides end face, on the fastening screw in described main pressure plate outside, be connected with tightening nut, on the fastening screw in auxiliary platen outside, cover has fastening sleeve, on fastening sleeve, be provided with lock screw radially, be connected with L shaped dial framework on main pressure plate, dial framework top end is provided with dial gauge.
Above-mentioned dial framework bottom is provided with vertical long strip and adjusts bolt hole, in described adjustment bolt hole, is installed with adjustment screw, and dial framework is connected with main pressure plate by adjusting screw.
Above-mentioned dial gauge vertically runs through dial framework top, and dial framework top end end face is laterally installed with set screw nut.
The beneficial effects of the utility model are: simple in structure, processing and fabricating is convenient, and cost is low, can be convenient and swift, carry out the operation of unit centering time saving and energy savingly, and adjust dial framework without repeated disassembled and assembled, data measured is accurate.Adopt the L-type can mileometer adjustment bar structure, be adapted to various different heights shaft joints.Axially adopt bracing structure, can adapt to different-thickness to wheel.Adopt locking nut structure, stiffening device stability, ensures to measure data true and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1 main pressure plate, 2 fastening screws, 3 auxiliary platens, 4 fastening sleeves, 5 tightening nuts, 6 dial frameworks, 7 dial gauges, 8 set screw nuts, 9 adjust screw, 10 lock screws.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to further detailed description:
As shown in Figure 1, a kind of junction box levelling device of the present utility model, comprises the fastening screw 2 that runs through coupling center hole, and on fastening screw 2, cover has main pressure plate 1 and the auxiliary platen 3 of being close to coupling both sides end face.The disk that main pressure plate 1 is middle perforate, auxiliary platen 3 is also the disk of middle perforate, size is suitable with main pressure plate 1.On the fastening screw 2 in main pressure plate 1 outside, be connected with tightening nut 5, on the fastening screw 2 in auxiliary platen 3 outsides, cover has fastening sleeve 4, on fastening sleeve 4, be provided with lock screw 10 radially, be connected with L shaped dial framework 6 on main pressure plate 1, dial framework 6 top end are provided with dial gauge 7.On main pressure plate 1, symmetrical 180 ° of positions have guiding groove, and dial framework 6 inserts in guiding groove and can slide up and down along guiding groove.Guiding groove sidewall separately has two screws, is convenient to the fixing of dial framework 6.Dial framework 6 bottoms are provided with vertical long strip and adjust bolt hole, adjust in bolt hole and are installed with and adjust screw 9, and dial framework 6 is connected with main pressure plate 1 by adjusting screw 9, adjusts lock bolt and can realize moving up and down of dial framework 6 in the position of adjusting in bolt hole.Dial gauge 7 vertically runs through dial framework 6 tops, and dial framework 6 top end end faces are laterally installed with set screw nut 8, by set screw nut 8, dial gauge 7 is fastened.
When use, dial framework 6 is inserted in the guiding groove of main pressure plate 1, regulate height, tighten and adjust screw 9, ensure that dial framework 6 is as a whole with 1 one-tenth of main pressure plate.Main pressure plate 1 is placed between two clutches, and fastening screw 2 penetrates in main pressure plate 1 from A coupling bolt hole, screws in tightening nut 5.Fastening screw 2 the other ends are installed pressing disc for fixing and fastening sleeve 4.Screw fastening sleeve 4, tightening nut 5, lock screw 10 simultaneously.Assurance device and A coupling become firmly entirety.Dial gauge 7 packs in main pressure plate 1 preformed hole, and the height of adjustment form allows dial gauge 7 contacts contact closely with B shaft joint, adjusts dial gauge 7 little pin and points to numeral 5, fastens with set screw nut 8, and adjustment dial plate makes zero.The moving rotor of dish, a secondary data is read in 90 ° of every rotations, rotate four times, calculates two mutually corresponding to the centre deviation data of taking turns by four dial gauge 7 readers.Then according to the requirement at Dui Lun center, by rational adjusting method, finally reach requirement.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
