- Date of publication：09-11-2019 Number of clicks：81 Classification：News
Construction elevator unit using have corresponding equipment installation project specialized contracting enterprise qualification certificate, should be in front of the building construction electrical installation to inform, formulate the construction elevator maintenance management system, equipment maintenance plan, accident emergency rescue plan, construction elevator maintenance management system and the equipment maintenance plan are clear, the specific content of the maintenance cycle and responsibility. The accident emergency rescue contract shall specify the person responsible for the accident emergency rescue, the mobiles phones number of the person responsible, and the service working time and response time committed. It is strictly forbidden to maintain the construction elevator at night.
Second, the construction of elevator safety operation rules
2.1 during the shift, the driver shall not leave the ladder cage post. When operating, the driver must keep his mind focused and keep his eyes open. In case of abnormal sound, stop the car immediately for inspection.
2.2 when the elevator is in operation, passengers must follow the driver's instructions. Unauthorized operation is strictly prohibited.
2.3 the load of the upper elevator should be evenly distributed in the cage, close to the center of the column as far as possible, and avoid unilateral bias. In case of thunderstorm, fog, frozen guide rail and wind force exceeding level 6, the driver is strictly prohibited to use the ladder cage and should dock at the ground.
2.4 in case of malfunction of electromagnetic brakes, speed limiter and other safety devices, stop the vehicle immediately and start the vehicle after repair.
2.5 the elevator must be lowered to the ground at the end of the work, disconnect the switch in the elevator cage and the main switch on the ground, cut off the power supply, and check the mechanical power part in the elevator cage for overheating or damage; Clean the elevator cage and record the operation of the elevator; Lock the electrical console and switch box.
2.6 the construction elevator driver shall take a mobiles phones with him when he is on duty (but it is forbidden to answer the phones during operation), so as to timely report the equipment situation and distress message.
Equipment maintenance requirements
Installation maintenance unit should according to the requirements of the relevant equipment safety technical performance for maintenance system, and according to the following procedure and steps to implement maintenance: equipment safety inspection before installation and maintenance: 3.1 the integrity of major institutional performance inspection equipment, check the main steel structure and pin shaft and fittings, bolts visible defects, check the equipment on the surface of the corrosion situation, form records, issue the installation.
3.2 daily maintenance of the equipment after delivery and use: the daily maintenance shall be undertaken by the operator of the equipment or the full-time personnel of the using unit. The installation, maintenance and maintenance unit shall have the obligation to supervise and inspect the daily maintenance. The main contents of daily maintenance are summarized as "cross operation" : cleaning, fastening, lubrication, adjustment, corrosion prevention. , 10 to 30 minutes at the end of the class a day shift, patrol equipment parts, each part is normal, according to the provisions of lubrication, mechanical operation of the note is normal voice, do a good job cleaning and succession, equipment appearance neat, in order to achieve the purpose of operating normally, daily maintenance records and hand-over records to make fixed form, and as the archives management.
3.3 regular inspection and maintenance in the process of equipment use: several times of maintenance and repair shall be carried out on the mechanical equipment within the specified time, centering on clarity, lubrication, adjustment, disintegration and maintenance. Generally by the maintenance personnel and operators to complete together.
Overhaul requirements: 3.4 when overhauling the equipment of the main assembly all reached the life time or close to the limit, a significant reduction in the mechanical dynamic performance, fuel consumption increase, the operation is ineffective, voice or a device can't display normal production conditions, the performance of adopted a comprehensive thorough resilience repair method, make the equipment in nature (performance) and from the appearance, the old as new should be to achieve. Overhaul should be carried out by maintenance transfer personnel, there should be records, there is acceptance.
Iv. Regular maintenance
Periodic maintenance of elevator equipment in construction shall include at least the following contents:
4.1 the following work contents required by the product user manual or instruction manual :(1) all work contents of regular inspection (including daily inspection, weekly inspection and quarterly inspection); (2) check, clean, lubricate and set; (3) replacement of wearing parts
4.2 inspection, test and replacement of safety devices and electrical protection devices shall comply with the relevant work requirements of "safety regulations for construction lifts" gb10055-2007, "safety regulations for lifting machinery" gb6067-85, "safety technical regulations for construction machinery use" jgj33-2001.
4.3 other regular inspection contents :(1) state changes of concrete foundation, anchor bolts, wall attachment device and anchor; (2) obvious defects visible to the naked eye such as deformation, cracks and corrosion of structural parts; (3) connection, corrosion and pin position of pin shaft, bolt, positioning plate and flange at the combination and connection of structural parts; (4) operation of the mechanism and wear of parts and components; (5) reliability and accuracy of protective devices and safety limiting devices; (6) abrasion of wire rope, roller slip or gear; (7) hydraulic device: pressure, pressure gauge, oil level, joint, pipe fitting, oil leakage, etc. (9) electrical installation: no loose parts, no sound at work, no aging wires, neat wiring, correct wiring (10). Lubrication: oil level of the transmission box meets the requirements, no dripping oil leakage is allowed (11). Grounding resistance value, insulation of wires and cables (12)
V. maintenance cycle
The periodic inspection and maintenance period of construction elevators shall not be more than once a month
Vi. Regular maintenance record of equipment
The installation and maintenance unit shall prepare a numbered record form for periodic maintenance of construction elevators and comprehensively record the contents of maintenance. After the regular maintenance of the construction elevator, the equipment installation and maintenance unit shall issue the regular maintenance record form of the construction elevator and put it in the technical file of the construction elevator machinery. The equipment installation and maintenance unit and the inspection and maintenance personnel shall seal and sign respectively. In addition, the equipment installation and maintenance unit should also timely fill in the curriculum vitae manual "equipment maintenance record".
