JiningMicro elThere is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least 2.5 meters.
Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
Jining.And the decoration team is also using aluminum alloy electric elevators. What safety considerations should we consider during the use process? Many manufacturers have not clearly indicated it. Today, the mechanical editor will talk to you about aluminum alloys
The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
.To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
Acceptance: Concrete strength grade C30, strength testing report.
The motor of the hydraulic guide rail lifting platform is set around the wellbore, improving the utilization rate of the wellbore area.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
Electric elevators should be regularly maintained and cleaned. During maintenance and cleaning, the bracket should be supported to prevent the electric elevator from overturning. Electrical and hydraulic systems should be maintained by professional personnel; When the battery level display is less than 40%
Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings,JiningFixed electric hydraulic elevator, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, remove the oil filter clean it with compressed air, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed and then return it to the oil tank and connect the pipeline.
Sincere service.The net height of the landing door opening should not be less than 8m except for the gap between the lower part of the door that should not exceed 35mm, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Installation materials.When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
Check the starter potential when the lifting table is not raised or the voltage is too low when the motor load is working. Voltage hydraulic range allowed&
When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed 35mm,JiningPortable electric elevator, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site,JiningIndoor electric elevator, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, stability, etc., and the production should meet the design requirements.
Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.
