The maintenance and care methods for construction hoist wall tie rods are essential to ensure their stability and safety. The following is a set of clear, point-by-point maintenance and care methods, combined with relevant figures and information in the reference article:
1. Daily inspection and maintenance
Check the connecting bolts:
Regularly check the connecting bolts of the construction hoist wall tie rod to ensure that they are not loose and tighten them in time.
Pay special attention to the bolts used to fix the wall tie rod to the building, such as M24 high-strength bolts, to ensure that they are not loose or damaged.
Check safety devices:
Check whether safety devices such as safety ropes and safety belts are intact to ensure that they can be used normally in an emergency.
Check lubrication:
Lubricate the lubrication parts of the construction hoist wall bracket according to the requirements of the lubrication table to ensure the smooth operation of all moving parts.
2. Regular inspection and maintenance
Quarterly inspection:
Carry out a comprehensive inspection of the construction hoist wall bracket every quarter, including mechanical equipment, safety protection devices, electrical systems, etc.
Pay special attention to checking the tightness of the bolts at each connection point of the wall bracket to ensure that there is no loosening or falling off.
Half-year inspection:
Carefully inspect the key components of the wall frame (such as connectors, fasteners, support structures, etc.) every six months to ensure that there is no plastic deformation or damage.
Use a feeler gauge or other tools to measure the gap between the guide frame roller and the main chord to ensure that the gap is above 0.6mm. If necessary, adjust or replace the guide frame roller in time.
Annual inspection:
Carry out an in-depth inspection of the construction elevator wall frame every year, including the deformation and stability of the steel structure, the installation and operation of the cable pulley and pulley guide rail, etc.
Check the accessories and functions of each limit switch and limit switch to ensure that they are flexible and without displacement.
3. Special maintenance and care
Cable take-up rack inspection:
Regularly check whether the cable take-up rack passes through the windbreak belt smoothly, whether the take-up rack is firmly fixed, and whether the windbreak belt rubber strip is severely worn.
Counterweight inspection:
Regularly check whether the counterweight guide wheel rotates flexibly, and whether the guide wheel and derailment guide plate are severely worn.
Lubrication and maintenance:
According to the requirements of the lubrication table, regularly add grease to the key parts of the construction elevator wall frame to ensure the smooth operation of all moving parts.
4. Summary
The maintenance of the wall tie rods of the construction hoist is the key to ensure its safe and stable operation. Through daily inspections, regular inspections and special maintenance, potential problems can be discovered and solved in time, the service life of the wall tie rods can be extended, and the safety and stability of the construction hoist can be improved. At the same time, operators should receive professional training, understand the maintenance knowledge of the equipment, and ensure the correct use and maintenance of the equipment.
