Description

Insert the formula commodity coal sampling thief that shakes

The present invention relates to the sampling device of commodity coal sample.More clearly say so and be used for taking the slotting formula commodity coal sampling thief that shakes of commodity coal sample from means of transports such as automobile, train, boats and ships.

At present, domestic thermal power plant goes into factory's coal missing-ton to lose the phenomenon of card very serious.Lose the main cause of card, be not have effective sampling chemical examination means.Domestic sampling way commonly used now is hand sampling.This method human factor is a lot, is difficult to realize car car, batch batch sampling chemical examination, false sampling or very general not according to standard sampling phenomenon.Therefore, hand sampling is difficult to satisfy the requirement of power plant's management modernization.Also there is several mechanical sampling system in past, and the product of domestic Lanzhou second cogeneration plant and external Ramsay company is the typical case comparatively.But the sampling head of this mechanical sampling system is spiral.During sampling, the sample coal will lean on spiral propeller to promote and carry, and can not promote relatively large sample, easily blocks.When impurity such as sampling head is run into gangue, large coal, freeze coal seam, lump pyrite or wooden unit, often idle running is adopted less than sample.Reliable inadequately during use.

Purpose of the present invention is to overcome above-mentioned shortcoming and defect, and providing a kind of can sample by industry standard automatically, thereby can realize car car, batch batch sampling chemical examination, raising power plant modern management level; Can reliably take a sample again simultaneously, for gangue, relatively large sample, the impurity such as coal seam, lump pyrite, wooden unit that freeze also can grab sample, can not block, can not adopt by sky; Thereby can be used for from means of transports such as the automobile of going into factory, train, boats and ships automatically, the slotting formula commodity coal sampling thief that shakes of reliable samples.

In order to achieve the above object, the present invention inserts and to shake that formula commodity coal sampling thief links to each other by power system, with power system and constituted with the sampling head of power system driving and the electric control system of power system and sampling head.Be different from spiral sampling head in the past, sampling head of the present invention is by fastening the main electric pushrod that promotes flange, be installed in 4 guideposts that promote on the flange, be welded on the push pedal of guidepost one end, 4 spring orienting sleeves that are sleeved on the guidepost other end and locate with 4 set nuts, be sleeved on the guidepost and lay respectively at 4 or 8 compression springs that promote the flange one or both sides, be welded on 4 thief rods in the push pedal, be welded on the fixed head on thief rod top, be welded on the sampling bucket of thief rod end, be fastened on the left electric pushrod and the right electric pushrod that promote on the flange, be fastened on the promotion cover of left electric pushrod and right electric pushrod end, be installed in promote in the cover about two little push rods, be enclosed within the little compression spring of little push rod end, be installed in the location-plate and the hold-down nut of little push rod end, with little axle be installed in the little push rod other end about two valve start arms, be welded on the start arm about two valve, being welded on that curtain shaft inboard and that be set in the axle sleeve that the valve upper end has constitutes about sampling bucket.

Electric pushrod is a kind of with motor-driven, through reducing gear, gyration is converted to the to-and-fro movement of push rod, thereby has the prior art of reciprocal promotion function.There are series of products can supply to adopt on the market.Sampling head of the present invention has adopted 3 electric pushrods: main electric pushrod, left electric pushrod and right electric pushrod.By promoting flange, 4 guideposts and 4 or 8 compression springs, 4 thief rods, will sample at last struggles against is advanced to the position of setting in the coal seam to main electric pushrod successively.This moment, left and right electric pushrod was pushed into simultaneously, and the inboard on the left and right two sides of sampling bucket is opened and be close to left and right two valve, and the sampling bucket inserts long-pending full coal sample in the coal seam.Then, under electric control system control, left electric pushrod is upwards closed left valve by promoting cover, little push rod and left valve start arm earlier.After left side valve is closed, main electric pushrod will be sampled to struggle against again and upwards be promoted one section small distance, make between sampling bucket and the coal seam below it and produce an intersegmental crack or loose coal seam.Subsequently, right electric pushrod is upwards closed right valve by promoting cover, little push rod and right valve start arm again.This program can guarantee that right valve closely is fastened on the left valve.At last, main electric pushrod upwards gos up, and the coal sample in the sampling bucket is promoted and takes out from the coal seam.The distance that main electric pushrod pushes can be set, thereby can take to set arbitrarily the coal sample of the degree of depth.The priority of left and right valve is closed and can be avoided relatively large coal, lump pyrite or gangue etc. to cause the sampling bucket to close the door, receive end difficulty in the middle of being stuck in two valve.About two valve length should be slightly less than sampling bucket inside length, its width then should be closed reliably to guarantee two valve greater than the inboard width of sampling bucket half.Two valve all can rotate around curtain shaft, start or stop.

The sampling bucket of sampling head is the rectangle tubular, and its bottom, four sides is sharp triangular shape so that insert the coal seam, reduce resistance, and can be used for breaking up gangue, coal seam etc. freezes.

1 vibrating motor that has eccentric block is installed on the fixed head of sampling head.During sampling, vibrating motor produces vibration, making the sampling bucket insert, when deviating from the coal seam coal seam shaken pine and will shake than gathering coal, gangue, freeze coal seam or other block broken, to reduce resistance, to guarantee to adopt coal sample at random.Be sleeved on vibration and main electric pushrod, the isolation of left and right sides electric pushrod, vibration damping that compression spring on the little push rod of main electric pushrod guidepost and left and right electric pushrod and little compression spring both can produce vibrating motor, the parts such as frame of avoid shattering the electric pushrod motor, sampling head being installed, electric pushrod is back and forth driven produce buffer action when promoting flange, little push rod, avoid collision, damage parts.

Or the thief rod that is welded in the push pedal has only one, one or two curtain shaft is being welded in its one or both sides, end, the curtain shaft upper sleeve through is installed with valve, welding start arm on the valve, start arm is with the little other end that is installed in little push rod, and corresponding electric pushrod and promotion cover, little compression spring, location-plate and hold-down nut also have one or two.

This incomplete structure fixed head, replaced sampling bucket with valve.Thief rod is inserted in the coal seam together with valve, drive valve to horizontal level with electric pushrod again, coal sample can be taken out.Simple in structure being suitable for.

Task of the present invention comes to this and finishes.

The invention provides a kind of can the sampling automatically by industry standard, can do not blocked by coal cinder, gangue, the foreign material such as coal seam or wooden unit that freeze during sampling, sky can not take place adopt phenomenon, sampling reliably, at random, the degree of depth can be set arbitrarily, the slotting formula commodity coal sampling thief that shakes easy to use.It can be widely used in thermal power plant goes in the sampling chemical examination of factory's coal, has extensive applicability for haulageman such as train, automobile, boats and ships, can realize car car, batch batch sampling chemical examination.Compare with the sampling in past, its sampling reliability improves greatly, has eliminated artificial unreal, factor such as play tricks, and the increment number has reached 100%, has improved 30～70% more in the past.
