Description
Technical field
The present invention relates to measurer technical field, more particularly, to a kind of Multidimensional Comprehensive detection limit for crane parts detection
Tool.
Background technology
Hoisting machinery is a kind of planar transportation equipment, and Main Function is the displacement completing weight.It can lighten one's labor by force
Degree, raises labour productivity, is the indispensable ingredient of modern production.Hoisting machinery helps the mankind to change conquering nature
Make in naturally activity it is achieved that the large piece article that cannot realize in the past lifts and mobile, with scientific and technical continuous progress
And the needs of China's economic development, make hoisting machinery have the huge market demand, hoisting machinery manufacturing was sent out in recent years
Exhibition is rapid, average annual growth about 20%.Hoisting machinery is important construction in the industries such as architectural engineering, metallurgical industry, power industry
Machinery, is also the jobs that requires special skills machinery that serious accident easily occurs.For example, on April 13rd, 2016 Dongguan City, Guangdong Province is sent out
Raw gantry crane together collapses and leads to builder's temporary shed to cave in the major accident causing 18 people dead；The Shanghai City generation of July 17 calendar year 2001
Gantry crane collapses the serious accident causing 36 people dead together；There is bridge-type together in April in 2007 Liaoning Province on the 18th Tieling
Craning weight of same falls and causes the serious accident of 32 people's death.The safety inspection of crane is particularly important as can be seen here, but crane
The risk factor that self structure contains is more, and it is all performance shape therein that big dolly gnaws rail, wire cable rupture, misfunctioning of brake
Formula.
Gnaw rail be bridge (door) formula crane or dolly in motor process, crane wheel (hereinafter referred to as wheel) is taken turns
Edge is contacted with track side surfaces, produces horizontal lateral thrust, causes friction and the abrasion of wheel rim and track.Gnaw after rail is likely to result in
Fruit includes：Shorten wheel service life, path wear is fast, increase running resistance, deteriorate Factory Building stand under load situation, so that wheel is climbed
Rail, easily make girder torsional deformation and crackle.And wheel is also to cause the main cause gnawing rail, including：Wheel lateral deviation, wheel
Vertical divergence, two active wheel diameters are unequal, front and back wheel is not run on the same line, wheel conicity direction setup error.
Therefore, there is inevitable contact between the two.One bridge crane of such as 2012 Nanjing Iron and Steel Group Co., Ltd
Derailment accident is it is simply that lead to cart wheel heavy wear due to gnawing rail, monolateral wheel rim comes off, and causes massive losses.Thus may be used
See, the direct reaction gnawing rail is exactly wheel wear, the wear extent of concern wheel may determine that the order of severity gnawing rail and estimates
Wheel obsolescence time limit.
Steel wire rope is one of strength member of hoisting machinery, is widely used in the lifting mechanism of crane, jib lubbing mechanism, traction
It can also be used to rotating mechanism, it is additionally operable to bundle department's rope rope of object, the tensioned lines of gin pole, cable crane for mechanism
With the carrying rope in Jia Chongkong road etc..Steel wire rope main failure forms be presented with fracture of wire, stranded and diameter reduces, in current check
In, except its fracture of wire of visual examination and stranded in addition to, mainly by measure its rope footpath to judge whether to meet use requirement.
Brake unit is to ensure that the vitals of crane safety normal work.In lifting job, brake unit in order to
Prevent the article suspending in midair or arm from falling；Prevent turntable or crane from acting on lower slider in wind-force or ramp component；Or make operating
The mechanism reduces speed, last stop motion；Run also dependent on job demand clamping weight；In particular cases, by control
Brake force and the balance of gravity, adjust movement velocity.In current check, remove visual examination, mainly to brake strip
Thickness, axle or the parameter such as shaft hole diameter wear extent, thickness of braked wheel measure.
At present the part of crane is carried out with safety inspection, mainly according to various measurers to the apparent size of part and chi
Very little variable quantity measures, by the data obtained calculate its whether meet use requirement judge whether qualified, according to being surveyed
The difference of parameter, needs various measurers.According to related request, the semblance measure measurer of crane parts includes vernier calliper
Chi, micrometer, dial gauge, straight steel ruler, tape measure, clearance gauge etc..And need multiple measurers and instrument cooperation, measurer in the measurements
Benchmark the factor such as is difficult to choose and causes easily to produce error, and the crane parts after installing rely on traditional method measurement to be difficult
Operation.
If can crane parts are detected accurate, portablely, including to crane wheel, pulley, braked wheel, rub
The parameter that pad, steel wire rope etc. can react abrasion condition is detected, obtains desired parameters, really implements national " safety in production "
Policy, many accidents can avoid completely.
At present, wheel can be divided into double wheel flange wheels, single wheel flange wheel and no three kinds of wheel flange wheel by wheel rim form, by tread
Shape can be divided into cylinder, cone and cydariform wheel.Also it is not quite similar for its measuring method of different wheels, and at present
Measuring method need multiple measurers use cooperatively.According to state's quality inspection pot [2002] 296《Hoisting machinery supervision and inspection code》
The regulation of the 5.7th, the survey tool that wheel wear is used is mainly slide calliper rule, in the detection foundation of other correlations also not
Clearly state.Specifically main test event method of testing is as follows：
1st, for the measurement of thickness of wheel rim：
Common method is with the slide gauge shown in Fig. 5, the thickness of wheel rim to be measured.This measuring method behaviour
Make relatively simple, but have the factor being unfavorable for accuracy：According to JB/T6392-2008《Crane wheel》In content, lifting
Inside locomotive wheel all there is the inclined-plane (as shown in Figure 1) that an angle is a in wheel rim.When being measured with slide gauge, due to
The depth of measurement can not accurately be determined, cause cannot accurately know the flange thickness of measured position.With JB/T6392-2008
《Crane wheel》In the maximum standard wheel enumerated, its flange height is 30mm, and a angle is 10 °, position 1 as shown in Figure 1
It is about 5.29mm with the difference of position 2, fathoms and also reached 0.18mm at interval of its error of 1mm, be unsatisfactory for detection required
The required precision wanted.
2nd, for the measurement of wheel tread diameter：
Conventional method is with slide gauge or miking tread diameter.But this method can only be less for diameter
Wheel, on the one hand want slide gauge or the micrometer that selected range is larger, measuring jaw is longer, generally require many people's cooperations, multiple
Measurement；On the other hand the wheel end carriage that has crane above it cover tread, have track to cover its tread (such as below
Shown in Fig. 2), cause slide gauge or micrometer to wheel cannot measure.
For the wheel being relatively large in diameter, Jiangsu Te Jian institute have developed and measured with π chi.By π chi around crane during measurement
On the excircle of wheel, both hands apply certain pulling force, using cursor principle reading, obtain final product the mean diameter value of measured piece.No
By measuring great diameter, all can achieve single measurement using measurement auxiliary (magnetic support).But for wheel, due to its position
On track (as shown in Figure 2), and be also often the place of wear extent maximum with the wheel tread of rail contact, this position cylindrical
Zhou Wufa with π chi be wound around, therefore π chi to part wheel also cannot realize easily measuring.
3rd, the diastrophic measurement for thickness of wheel rim：
Conventional method is to measure (as shown in Figure 3) with horizon rule cooperation clearance gauge.The method is in wheel with horizon rule
The outside of edge, side is adjacent to wheel rim, and side is padded with clearance gauge, and when horizon rule bubble is located at center, the thickness of clearance gauge is
Deflection, then compare with the thickness of wheel rim, determine whether exceeded.The shortcoming of the method mainly has following three points：1) 2 kinds of amounts are needed
Tool uses cooperatively, not easy to operate；2) cannot accurately judge wheel rim root in which position, easily cause the datum mark that clearance gauge puts not
Accurately, in turn result in data and produce error；3) horizon rule to be kept contact with wheel section is good, generally uses the afterburning patch of handss
Tightly, then padding chi, firmly different measuring result is just different, have impact on accuracy.
4th, for the vertical divergence of wheel：
Using frame level and clearance gauge, similar with the diastrophic measuring method of thickness of wheel rim (as shown in Figure 4).
But the shortcoming of the method is also similar with thickness of wheel rim diastrophic measuring method shortcoming 1,3.
And the measurement for parts such as pulley, steel wire rope, brakes, its current measuring method is similar with wheel with drawback,
Do not carry out repeating to illustrate.
In sum, currently there is no the measurer of special efficient detection crane parts both at home and abroad.
