A, elevator shaft wear reason of hoist common ascension of the cement industry is high, high altitude compare.
Hoisting machine in the process of operation because of its high altitude high load of bearing driving part damage is serious.
At the same time, the heavy load lifting equipment have a counterweight, the impact of vibration in the process of operation, also compare the use conditions, in the process of long-term operation, smooth once present problems of bearing will incur jammed phenomenon, in turn, affect the normal rotation of the bearing, attacks and bearing wear condition.
Second, the elevator at the site bearing wear of step 1.
First of all, according to the drawings or on-site measurement of manufacturing tooling;
2.
To do a good job of preparation, that is, the removal of equipment, tooling processing, related tools and the preparation of personnel to ensure enough space construction and safe working environment;
3.
Shaft appearance's preliminary work of liquidation, locating surface appearance and bearing oil is wiped clean, and removing high, burr, rust, etc. ;
4.
Will be wiped clean outside tooling, and the two semicircle tooling tighten well, use measurement tools to detect processing precision tooling, including positioning size, fix size and roundness of tooling diameter;
5.
Tooling size measurement must be qualified after the end of stop empty pack be on probation;
6.
Empty be on probation after loading, must under the premise of tooling complete qualified, beginning to stop further repair work;
7.
Disposal: appearance using the oxygen acetylene to stop baking disposal of oil bearing a appearance, until no sparks, then bearing a oxidized to grind the clean appearance, show metal primary colors;
8.
Using anhydrous ethanol bearing a appearance looks to clean clean, ensure no dirt, dry;
9.
By using anhydrous ethanol tooling in appearance, the discharge of the tank and the orientation of bolt and bolt hole, pin and pin hole, etc to wipe clean, dry;
10.
Tooling in appearance, the discharge of the tank, bolts, bolt hole, dowel pin, positioning pin hole to wipe a layer of thin sauvy SD7000 release agent, the thinner the good, dry spare;
11.
According to the empty be on probation when doing certain bearing wear depth, calculate the dosage of materials;
12.
Strict according to the proportion of harmonic sauvy SD7104 data, harmonic average colorless difference;
13.
Will reconcile good sauvy carbon nano polymer materials hurtling to the bearing daub appearance: the first layer repeat operation pressure, to ensure that materials and bearing a appearance of energetic glue, and then apply to the entire surface of the shaft on average, daub is slightly larger than the thickness of bearing an uneven wear;
Tooling in appearance also apply a layer of thin materials;
14.
The tooling hurtling device in place, good fastening bolts and positioning pin.
Pay attention to during the process of device to examine tooling device location, fastening tooling to prevent in the process of tooling deformation at the same time.
If the room temperature is lower, stop the appropriate heating of tooling appearance;
15.
From harmonic information to tooling equipment, the end of the process must be completed in 15 minutes;
16.
Curing: 24 ℃, environment temperature initiative to remove tooling time not less than 4 hours;
Environmental temperature 24 ℃, 60 - initiative by using iodine tungsten lamp heat
80 ℃ of not less than 3 hours;
17.
Be careful when remove tooling, or remove the data in the process of injury is shattered;
18.
After removal of tooling to remove redundant data;
19.
Back pack parts: according to the time back to the parts, assembly bearing initiative heated to 100 - at the same time
120℃。
Three, elevator shaft wear repair case
