The specific embodiment
The car method processed of elevator grooving of the present invention is based on by two poor principles of calculating semidiameter of waney concentrically ringed girth.Suppose that large and small two groovings are concentric circles, wherein little radius of a circle is made as r, and large radius of a circle is made as (r+x), and the girth of great circle is L=2 π (r+x), roundlet girth is l=2 π r, and the difference of the girth of two circles is: c=L-l=2 π (r+x)-2 π r=2 π x.Wherein, c is every rotation one week, and the line length that great circle has more than roundlet is measured the value of c, just can calculate the value of the difference x of radius, is the depth of cut of this grooving.
Below with reference to accompanying drawing, specific embodiments of the invention are described in detail.
Fig. 1 shows according to Hoisting System structure in the car of elevator grooving of the present invention method processed; Fig. 2 is the structure for amplifying of structure 3 in Fig. 1.
As shown in Fig. 1 and Fig. 2 are common, the Hoisting System relating in the present invention comprises elevator 1, steel wire rope 2, hydraulic lift hitch 3 and hoisting container 4; Wherein, steel wire rope 2 is many, is wrapped in respectively on elevator 1, and its quantity equates with grooving number, and steel wire rope 2 is connected with hoisting container 4 by hydraulic lift hitch 3.The quantity of hydraulic lift hitch 3 equates with steel wire rope 2 quantity; Hydraulic lift hitch 3 comprises framework 1, framework 2 34, hydraulic cylinder 31 and hydraulic cylinder push rod 32.The flexible of hydraulic cylinder 31 can drive the movement of hydraulic cylinder push rod 32 and stretching of framework 1 and framework 2 34, and then regulates the length of the steel wire rope 2 hanging, and the variable quantity of steel wire rope 2 length can represent with the stroke of hydraulic cylinder 31 like this.
In the specific embodiment of the invention, implementation step is as follows:
Elevator 1 rotates the number of turns and is set to 20, as the foundation of calculating the shifting amount of each steel wire rope 2, establishes n=20.
1, first, each lathe tool is aimed to grooving separately, adjust the depth of cut, then rotate elevator 1 and do micro cutting, at each lathe tool, be all just labelled to groove bottom and when very close to each other, write down scale as the cutting zero-bit of each lathe tool; Again hoisting container 4 is parked in to well head horizontal level, on steel wire rope, makes the initial position mark of each hydraulic cylinder 31.If Fig. 3 is according in the car of elevator grooving of the present invention method processed as shown in each hydraulic cylinder initial position mark, with the initial position of each hydraulic cylinder 31 of A mark, as the basis of each root steel wire rope 2 shifting amount.
2, then, rotating elevator 1 rolls, make hoisting container 4 descending, it is rear out of service that elevator 1 rotates setting value 20 circles, now on corresponding steel wire rope 2, make the final position mark of each hydraulic cylinder 31, if Fig. 4 is according in the car of elevator grooving of the present invention method processed as shown in each hydraulic cylinder final position mark, with the final position of each hydraulic cylinder 31 of B mark.In conjunction with initial position mark, can measure each hydraulic cylinder 31 with respect to the stroke of initial position separately, that is to say the shifting amount of each corresponding steel wire rope; Wherein flexible direction represents with arrow, and arrow upwards represents that hydraulic cylinder 31 is up with respect to initial position, and arrow represents that hydraulic cylinder 31 is descending with respect to initial position downwards.
In the specific embodiment of the invention, what elevator 1 adopted is 2.8m friction type winder, and after elevator 1 rotates 20 circles, each hydraulic cylinder 31 corresponding to the collapsing length of initial position separately and direction as shown in Figure 4.Since a side record, be respectively: descending 30mm, up 30mm, descending 15mm, descending 125mm, up 96mm, up 35mm.
In this step, in hydraulic cylinder 31 telescopic process, if there is the hydraulic cylinder push rod 32 of indivedual hydraulic cylinders 31, channel in advance the situation of hydraulic cylinder bottom, can suitably reduce the rotation number of turns of elevator 1, avoid the generation of this phenomenon.
3, poor according to being girth by two poor shifting amount of calculating known each steel wire rope of principle of semidiameter of waney concentrically ringed girth, the steel cable 2 of shifting amount minimum of take is benchmark, calculate the shifting amount of relative this rope of other each rope, and then can draw and the semidiameter of each grooving be lathe tool in the depth of cut of each grooving.
Data and direction by upper figure and record can be found out, after hoisting container 4 is descending, there is steel cable 2 upwards to alter to have gone 96mm, illustrate that its Top Runby is maximum, relatively alter rope amount minimum, grooving diameter is also minimum, and getting this steel wire rope 2 is benchmark, starts each rope of record corresponding shifting amount m downward with respect to this benchmark rope and is respectively: 126mm, 66mm, 111mm, 221mm, 0mm, 61mm from recording same side described in play length.
According to formula c=L-l=2 π (r+x)-2 π r=2 π x, can obtain:
20c=20×2πx=40πx=m，
x=m/40π
Wherein, c is that girth is poor, and m is shifting amount, and x is the depth of cut.
By in the above-mentioned formula of each steel wire rope 2 shifting amount m value substitution, draw the depth of cut x of each grooving respectively.Corresponding x data record is: 1mm, 0.52mm, 0.88mm, 1.75mm, 0mm, 0.48mm.
4, by the feed value of each grooving obtained above, adjust lathe tool feed, make the depth of cut be respectively 1mm, 0.52mm, 0.88mm, 1.75mm, 0mm, 0.48mm, then cut, the footpath, the end of reducing each grooving is poor, and then reduces the generation of altering rope phenomenon.
5,, in order to reduce error, after grooving car system one time, operating procedure 1～4 again, obtains data as follows:
Play length and direction are respectively: up 20mm, 0mm, descending 40mm, descending 15mm, up 30mm, 0mm;
Downward shifting amount m with respect to basic steel wire rope 2 is respectively: 10mm, 30mm, 70mm, 45mm, 0mm, 30mm;
Same principle is brought the shifting amount m value of each steel wire rope 2 into depth of cut x that formula c=L-l=2 π (r+x)-2 π r=2 π x calculates each grooving and is respectively: 0.07mm, 0.23mm, 0.55mm, 0.35mm, 0mm, 0.23mm.
By above-mentioned numerical value, change the lathe tool depth of cut and carry out turning for the second time, so repeat two to three times, each grooving diameter deviation that car goes out will be more and more less.The maximum shifting amount of steel wire rope can be controlled in certain limit, and then diameter deviation at the bottom of each grooving is controlled in code requirement.
In sum, the car of elevator grooving provided by the invention method processed, adopts the thinking of " getting two; in the middle of going ", other error links in the middle of ignoring, only by final deviate, each relative slippage difference of restricting as each grooving turning according to feeding back.Can effectively reduce the dimensional discrepancy of grooving like this, can effectively prevent simultaneously hoisting rope in drum groove back and forth friction slide, the generation of play phenomenon, thereby reduce the hoisting rope infringement that friction is slided back and forth in drum groove, play causes rope and grooving.
Above with reference to Fig. 1 to Fig. 4, in the mode of example, describe according to the car of elevator grooving of the present invention method processed.But, it will be appreciated by those skilled in the art that the car method processed of the elevator grooving proposing for the invention described above, can also on the basis that does not depart from content of the present invention, make various improvement.Therefore, protection scope of the present invention should be determined by the content of appending claims.
