-How to install the docking chain for scraper conveyor?
Head and tail transmission parts of scraper conveyor
1. The machine head, tail, transition groove, and bridge are not welded. 2. The connection between the headstock, tailstock, and transition groove should be tight. The interlocking of up, down, left, and right should not exceed 3mm.
3. The pressure chain connection should be firm and the wear should not exceed 6mm.
4. The entire sprocket assembly and blind shaft installation comply with the technical document requirements.
5. The head shaft and tail shaft should rotate flexibly without any jamming or collision.
The second is the mechanical transmission device of the scraper conveyor
1. The dimensional accuracy, roughness, and positional tolerances of each axis hole in the shell meet the requirements of the technical documents.
2. The threaded holes and positioning holes on the shell and connecting cover meet the requirements of the technical documents.
3. The bearing has no obvious signs of wear and the clearance meets the requirements.
4. The fasteners do not show significant plastic deformation.
5. Each component is undamaged, with no obvious signs of wear or deformation.
6. Update all seals and hoses.
7. During assembly, each component should be carefully cleaned and free of rust spots, and there should be no dirt inside the casing.
8. Each transmission department meets the requirements of the technical documents after installation and adjustment.
9. Inject lubricating oil into the reducer according to regulations. Perform a pressure test on the hydraulic coupling and inject the specified type and volume of medium.
10. According to the requirements of the technical documents, conduct dynamic balance tests on brake discs, couplings, and couplers.
11. The reducer and sprocket components have no leakage. The lubrication devices are diverse, intact, and leak free.
12. After the major overhaul, there was no jamming during the manual test run.
Three scraper conveyor chain wheel, tongue plate, chain splitter
1. The tooth surface of the sprocket should be free of cracks or severe wear. The wear of the horizontal ring chain plane supported by the sprocket should not exceed 5mm when the pitch is ≤ 22mm, and 6mm when the pitch is ≥ 22mm (a horizontal ring chain can be placed on the sprocket, and the distance between the surface of the ring chain and the hub should be checked).
2. The sprocket must not have axial movement. The gap between the double-sided sprocket and both sides of the frame should meet the design requirements, generally not exceeding 5mm.
3. The protective plate and chain splitter are not deformed, and there is no jamming or collision during operation. The tongue plate shall not have cracks and wear shall not exceed its original thickness. 20.
4. In the technical documents, the materials and dimensions of the elastic elements and shear pins of the coupling should meet the requirements.
5. The protective cover of the scraper conveyor has no cracks, no deformation, and is firmly connected.
Four scraper conveyor body
1. Scraper, chain
The bending deformation of the scraper shall not exceed 5mm. The length wear of the middle double chain and middle single chain scraper shall not exceed 10mm.
⑵ The elongation and deformation of the chain shall not exceed the design length of 2. The wear of the chain ring diameter shall not exceed 1-2mm.
When assembling old chains, chains with the same degree of wear should be assembled together to ensure consistent chain length.
The bolt and nut models and specifications are consistent and used for connecting scraper and chain.
