Detailed Description
The present invention is described in further detail below to enable those skilled in the art to practice the invention by reference to the specification and drawings.
Example 1:
the method for measuring and adjusting the deviation of the sintering machine specifically comprises the following steps:
step one: placing a datum line at the center of a head and tail wheel of the sintering machine 4, placing a parallel line by taking the axes at two ends of a main transmission shaft of a head and tail of the sintering machine and taking the axes as endpoints to detect whether the slide paths of the head and tail wheels of the sintering machine 4 are on the same datum line, and measuring the deviation of the level and elevation of the track and the slide paths, wherein the specific measurement is as shown in the following table:
table one: measuring position
It can be seen from the table that the track level deviation is not large, at maximum 5mm.
The measurement data shows that the error from the head to the tail to the rail is larger than 4mm, and the horizontal elevation deviation of the rail and the slideway is large.
Step two: the synchronous measurement horizontal elevation of the tooth plate 2 of the head star wheel 1 and the tooth plate 2 of the tail of the sintering machine 4 is measured by using a reaming bolt positioned by the tooth plate 2 as a measuring point and at the same position, and the specific see the following two:
and (II) table: the reaming bolt is used as a measuring point and the same position is used for measuring
The measurement results are shown in Table II, and the maximum deviation is 15mm and the average deviation is 14mm when the star wheel 1 and the toothed plate 2 at the head of the sintering machine 4 are not synchronous.
Step three: analysis of reasons for deviation of the sintering machine 4: because the toothed plates 2 are not synchronous, when the sintering machine 4 enters the head star wheel 1 to bend, the left toothed plate 2 and the right toothed plate 2 are not meshed with the left wheel and the right wheel of the trolley, so that the track of the trolley entering the bend is changed, and the trolley is deviated when entering the horizontal track. The reason for the asynchronous toothed plate 2 is that the head wheel hub has no positioning key, the installation accuracy is not enough, and the angle deviation occurs during the installation.
Step four: according to the detection data, if the deviation problem is to be thoroughly solved, the star wheel 1 star teeth at the head part of the sintering machine 4 need to be replaced. Firstly, the time is not up, secondly, spare parts are not available, and the spare parts are expensive in cost. According to the actual measurement result, an adjusting method for preventing the deviation of the sintering machine is provided based on the method: as shown in fig. 1, the toothed plate 2 on the left side of the head star wheel 1 of the sintering machine 4 is made into an eccentric toothed plate 2, and the toothed plate 2 on the left side of the head star wheel 1 of the sintering machine 4 is thickened toward the error side.
The toothed plate 2 on the left side of the head star wheel 1 of the sintering machine 4 is increased to an error side by a thickness 3 of 10mm.
Example 2
Unlike example 1, the toothed plate 2 on the left side of the starwheel 1 on the head of the sintering machine 4 was increased by a thickness 3 of 14mm to the error side.
Comparative 1
Unlike example 1, the toothed plate 2 on the left side of the head star wheel 1 of the sintering machine 4 had an increased thickness 3 of 16mm toward the error side
The installation mode of the sintering vehicle and the head star wheel 1 is shown in fig. 2, the feasibility of the scheme is verified for the safety of equipment operation, and the following debugging scheme is specially prepared. Firstly, a belt is used, the thickness of an elastic pad is made to be 10mm, the belt is padded on a toothed plate 2 on the south side by a person in the rotation process of a sintering machine 4, after a trolley runs for 2 hours, the deviation phenomenon is obviously lightened, when the thickness of the belt is added to 16mm later, the trolley runs for 2 hours, and the deviation direction of the trolley changes the deviation of the trolley to the right side, because of thickening of the belt pad. And then the cushion is reduced to 14mm, and after the trolley runs for 2 hours, the trolley running track normally deviates and the bottom measurement disappears.
Experiments prove that the toothed plate 2 on the left side of the head star wheel 1 of the sintering machine 4 is made into the eccentric toothed plate 2, the toothed plate 2 on the left side of the head star wheel 1 of the sintering machine 4 is thickened to one side of an error, so that the running track of the sintering machine 4 is stable, the phenomenon of off tracking and rail biting and trolley wheel abrasion is avoided, the running track of a trolley is basically straight, the phenomenon of rail biting is avoided, the trolley wheels are not abraded any more, the upper sliding plate and the lower sliding plate are abraded uniformly and flatly, the air leakage rate of the sintering machine 4 is effectively reduced, and the embodiment 2 in the embodiment is the best embodiment.
Although embodiments of the invention have been disclosed above, they are not limited to the use listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Further modifications may readily be effected by those skilled in the art, and the invention is therefore not limited to the particular details without departing from the general concept defined by the claims and the equivalents thereof.
