What should be done before disassembling asphalt mixing equipment?
Release Time:2023-11-09
After use, asphalt mixing equipment needs to be disassembled, cleaned, and maintained before it can be saved for next use. Not only is the disassembly process of the equipment important, but the previous preparation work also has a greater impact, so it cannot be neglected. Please pay attention to the detailed introduction below for specific content.
Since the asphalt mixing equipment is relatively large and has a complex structure, a feasible disassembly and assembly plan should be developed based on the location and actual situation before disassembly, and instructions should be given to relevant staff. At the same time, it is necessary to inspect the equipment and its components; ensure that the power supply, water source, air source, etc. of the equipment are turned off.
In addition, asphalt mixing equipment should be marked with a unified digital identification positioning method before disassembly. Especially for electrical equipment, some marking symbols should also be added to provide a basis for the installation of the equipment. In order to ensure the installability of the operation, appropriate machines should be used during disassembly, and the disassembled parts should be properly kept without loss or damage.

During specific disassembly, it is recommended to implement a division of labor and responsibility system for equipment disassembly and assembly, and formulate and implement relevant plans to ensure that the entire process of disassembly, hoisting, transportation and installation is safe and accident-free. At the same time, the principles of first small before large, first easy before difficult, first ground before high altitude, first peripheral before main engine, and who dismantles and installs are implemented.
Disassembly points
(1) Preparation work
Since the equipment is relatively complex and large, before disassembly and assembly, a practical disassembly and assembly plan should be formulated based on its location and actual on-site conditions, and a comprehensive and specific safety technical explanation should be given to the personnel involved in the disassembly and assembly.
Before disassembly, the appearance inspection and registration of the equipment and its accessories should be carried out, and the mutual position diagram of the equipment should be mapped for reference during installation. You should also work with the manufacturer to cut off or remove the power supply, water source, and air source of the equipment, and drain the lubricating oil, coolant, and cleaning fluid.
Before disassembly, a unified digital identification positioning method should be used to mark the equipment, and some marking symbols should be added to the electrical equipment. Various disassembly symbols and signs must be clear and firm, and positioning marks and positioning size measurement points should be permanently marked at relevant locations.
(2) Disassembly process
All wires and cables are not allowed to be cut. Before disassembling the cables, three comparisons (internal wire number, terminal board number, and external wire number) must be made. Only after confirmation is correct can the wires and cables be disassembled. Otherwise, the wire number identification must be adjusted. The removed threads should be firmly marked, and those without marks should be patched up before disassembly.
In order to ensure the absolute safety of the equipment, appropriate machines and tools should be used during disassembly, and destructive disassembly is not allowed. The removed bolts, nuts and positioning pins should be oiled and screwed or inserted back into their original positions immediately to avoid confusion and loss.
The disassembled parts should be cleaned and rust-proofed in time, and stored in designated locations. After the equipment is disassembled and assembled, the site and waste must be cleaned up in time.
