Hydraulic Acrow Props

Single Hydraulic Prop Repair Process Steps Are Mainly Divided Into The Following Steps:

1. To Be Repaired Single Hydraulic Prop Into The Plant Acceptance

Hydraulic prop maintenance to the maintenance of hydraulic acrow props pre-inspection. Mainly count the number of missing parts, rank parts, scrap parts; fill in the "maintenance acceptance sheet.

2. Hydraulic Acrow Props Repair Before Identification

Hydraulic Acrow Props maintenance personnel should be based on the damage to the bracket to be repaired in the place of sampling and removal. Hydraulic bracket column jack up tension cylinder situation, pin wear and corrosion, component damage and valve 1 ] damage to the overall assessment, the need to fill out the identification report.

3. To Be Repaired Suspension Hydraulic Prop Soaking And Flushing

The suspension hydraulic prop to be repaired is transferred to the soaking and flushing workshop, and after soaking in the soaking pool for 24 hours, it is transferred to the flushing area for coal flushing. The coal in the base column nest is soaked to facilitate cleaning. Reduce the dust pollution area and improve the cleanliness of the workshop.

4. Disintegration Of Single Hydraulic Prop

After soaking and flushing, the single hydraulic prop will be transferred to the dismantling workshop for disassembly of the bracket.

5. Sorting And Placing Of Hydraulic Acrow Props

The disassembled hydraulic acrow props parts are classified and arranged, and the disassembled parts are inspected after quality inspection, and the repair parts are classified according to the quality inspection results. According to the result of quality inspection, we will repair each part to avoid the omission of selection or insufficient maintenance, improve the efficiency of maintenance and increase the rate of qualified after maintenance.

6. Ballast Treatment

After the quality inspection of the hydraulic acrow props parts to the shot blasting workshop, shot blasting treatment; remove the surface of the structure of the rust, improve the adhesion of paint, improve the ability to prevent rust.

7. Brush Primer

Single hydraulic prop maintenance will be transferred to the spray painting workshop after the slurry treatment of the single hydraulic prop structure parts for primer treatment; after the blasting treatment of the structure parts, the primer treatment should be completed within 24 hours. Avoid long term leakage of structural parts after shot blasting, which cannot achieve the ideal effect of rust prevention: after shot blasting, the primer treatment of structural parts should be completed within 24 hours. The primer treatment of structural parts should be completed within 24 hours after blasting.

8. Maintenance

The disassembled single hydraulic prop are transferred to the suspension hydraulic prop maintenance workshop for maintenance;the structure to be repaired after painting primer is transferred to the structural parts maintenance workshop for maintenance.

9. Assembly

After suspension hydraulic prop repair, each component passes quality inspection and is transferred to the assembly area for assembly; the parts entering the assembly area are qualified products, and no maintenance of parts is carried out in the assembly area, so the cleanliness of the work area should be improved; the pass rate of the above items reaches more than 80%.

10. Delivery inspection

Quality inspection of the suspension hydraulic prop to ensure the qualified rate of the factory bracket; quality inspection report will be issued according to the quality inspection.
