Abstract
The utility model discloses a gate positing measuring tool, including pi chi and locking plate, a plurality of locking holes of evenly distributed on the pi chi, the locking plate is one and can blocks on locking the hole and the bolt card of fixing. This gate positing measuring tool can the actual aperture of direct read stator, has improved measurement accuracy and work efficiency, has reduced simultaneously and has forgotten in the inside danger of runner because of equipment.
Description
Technical field
This utility model is related to a kind of survey tool, particularly to a kind of guide vane opening survey tool, for various manufactures
The public infrastructure fields such as industry, power station, the installation of hydroenergy storage station movable guide vane.
Background technology
In the installation process of power station, in order to obtain unit servomotor and guide vane opening relation curve, need to be to guide vane opening
Measure, and the metering system of current guide vane opening has the following two kinds：One is can to read from stator displacement transducer, two
It is by now measuring the actual aperture of stator, need sensor is arranged on equipment using first method, life-time service is easy
Sensor is easily damaged therefore easily so that the data measured is inaccurate, and the second way is that survey crew enters in spiral case
Portion measures guide vane opening, but the usual method of this kind of measurement is to be measured using scissor forceps and ruler, and this way compares
Slightly, and excessive instrument is brought into inside spiral case, this mode is easily forgotten instrument inside spiral case, brings to normal operation of unit
Great risk.
Utility model content
For solving problem above, the purpose of this utility model is to provide a kind of guide vane opening survey tool, by a π
Chi survey tool can achieve to directly read measures guide vane opening, by adjusting π chi length, to adapt to different guide vane opening measurements,
Also just multiple guide vane opening point measurements.
For achieving the above object, this utility model is achieved through the following technical solutions：
A kind of guide vane opening survey tool is it is characterised in that include π chi and locking plate, if being uniformly distributed on described π chi
Dry lock hole, described locking plate may be stuck on lock hole for one and securing bolt card.
Further, the length of described π chi can design open range according to stator and choose, according to the reality in usual power station
Border situation, maximum opening of guide vane is not over 500mm, of length no more than 500mm of π chi.
Further, carry for convenience and π chi is rolled into an annulus, simultaneously for guaranteeing certainty of measurement and meeting difference and lead
Measurement under leaf aperture, π chi is coiled and is less than 3 layers.
Further, for protecting π chi, the annulus periphery coiled in π chi arranges π chi set.
Further, the quantity of described lock hole requires to determine, required certainty of measurement is higher according to required certainty of measurement
Hole arranges closeer.
This utility model compared with prior art, has an advantage in that：The actual aperture of stator can be directly read, improve survey
Accuracy of measurement and work efficiency, reduce simultaneously because equipment forget in runner within danger.This stator survey tool is easy to make,
Conventional mechanical part job shop can make, and structure material is common iron, and convenient, low price, tool are bought in market
There is preferable application prospect.
Brief description
Fig. 1 is the structural representation of this utility model guide vane opening survey tool；
In figure：1st, π chi, 2, locking plate, 3, π chi set, 4, lock hole.
Specific embodiment
Describe the embodiment of this utility model structure in conjunction with accompanying drawing in detail：
Because Power Plant Design is inconsistent, lead to the maximum opening of stator inconsistent, and stator has under a variety of operating modes
Aperture, therefore can choose suitable π chi length according to guide vane opening design load.
Guide vane opening survey tool, including π chi 1, locking plate 2, π chi set 3, lock hole 4.π chi is a standard π chi, only
Some lock holes 4 need to uniformly be stamped on standard π chi 1, the number of lock hole 4 requires to determine according to required certainty of measurement, precision
Higher, the number of lock hole is more, and the distribution of lock hole is closeer.Many people watch for convenience, are inserted in the lock of π chi 1 with locking plate 2
Determine in hole 4, carry for convenience and π chi is rolled into an annulus, simultaneously for guaranteeing certainty of measurement and meeting under different guide vane openings
Measurement, π chi is coiled and is less than 3 layers, simultaneously neat for convenience of π chi, is entangled, with π chi set 3, the π chi 1 coiling into annulus.
Guide vane opening measures concrete operation step：
First, guide vane opening survey tool makes.The maximum opening of certain power station movable guide vane is 236.5mm（120% open
Degree）, then select the standard π chi of a 500mm, the 20mm scale value of π chi covered monolateral fixation with π chi（Regular length is substantially
50mm）, and some holes are beaten on π chi, hole spacing is the minimum scale of π chi（As 1mm）, now π is inserted in π chi other end
To coil into a circle in chi set, coil for convenience, arrange another π chi set, two π chi set docking in π chi set offside simultaneously
Minimum diameter is 100mm afterwards（Set with specific reference to actual value）；
Second, movable guide vane aperture measurement.When scene needs to measure movable guide vane 100% aperture, hold the survey made
Amount instrument enters in spiral case, and the size of calculating movable guide vane 100% aperture is 197mm, therefore first by the scale of survey tool 197mm
Value is corresponding with 0mm scale value and is fixed with π chi locking plate, and one hand holds survey tool and level pushes it into two phases
Between adjacent movable guide vane, passing in and out back and forth, if there being bite, instrument being taken out, reduce π chi scale value and fixed with π chi locking plate
Good, if freeing in and out and have gap, amplify certain size, repeat the above steps measurement takes out instrument simultaneously directly after meeting requirement
Read data and record；Vertically translate this instrument again after completing the measurement of this point, pass in and out back and forth between two adjacent activities stators, with
Check movable guide vane aperture whether consistent and phenomenon that is whether having inclination, after the completion for the treatment of whole measurement process, take instrument out of spiral case
Interior.This utility model is the manufacturing, equipment for hydroelectric station is installed, debugging solves device measuring precision and work efficiency etc.
Problem.
Above content be with reference to specific preferred implementation further detailed description of the utility model it is impossible to
Identification is of the present utility model to be embodied as being confined to these explanations.Ordinary skill for this utility model art
For personnel, make some equivalent substitutes or obvious modification without departing from the concept of the premise utility, and performance or
Purposes is identical, then should be considered as belonging to the protection domain of claims determination that this utility model is submitted to.
