ZhongshanElectThe full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
Stage equipment safety door. To prevent personnel from extending their heads, hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, its cabin should be full of doors and the height of the hoistway (hall door) should not be less than 8 meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
Zhongshan.The coaxiality between the motor shaft and the worm shaft in the aluminum alloy electric elevator drive device should be less than 0.1mm,ZhongshanElevator electric micro, and there should be a 2mm gap at the shaft end to ensure that the motor bearings bear reasonable loads and reduce motor operating noise; electric
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
.Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.
Aluminum alloy lifting platforms can be divided into single column aluminum alloy, cargo elevator, double column aluminum alloy, three column and four column aluminum alloy. Can be used in factories,ZhongshanSmall electric screw elevator, automated warehouses, municipal facilities, docks, buildings, and installations
Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
Honesty and mutual benefit.Then, the lifting platform platform platform that carries the load needs to be balanced, and no deviation of one side is allowed. The lifting of goods does not allow people to stand on both sides of the platform,ZhongshanElectric background axis elevator, the bearing capacity of its supporting structure should be checked.
Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether the sealing rings are damaged or ineffective, whether there is a lack of hydraulic oil, and whether the oil cylinder is leaking. It is necessary to clean the lifting frame scissors, wiring, and oil cylinder once a week to avoid dust and debris affecting normal operation.
Job description.When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
Electric lifting machinery, as an important product of social development in China, has a high social status and has now become an irreplaceable operational tool in our mainstream goods. The hydraulic pump station is the heart position of electric lifting machinery, which greatly tests the professionalism and attention of operators. It is our common responsibility to inspect it and ensure the daily use of machinery. Let's take a look at a few common sense issues: the manufacturer of electric elevators is to ensure the correctness of the power connection, and there should be no misconnection or leakage; Pay attention to cleaning work in daily life and do not allow stains to corrode it; When standing still, regular maintenance should be carried out to prevent the impact of rain and snow weather; Overloading is the first thing that operators must comply with; Iron Law&# quo;; The adjustment of the solenoid valve cannot be done arbitrarily and must be checked and certified by a professional organization; Especially when conducting outdoor operations under high temperatures, it is necessary to always pay attention to the abnormalities of the pump station; It is very normal for us to encounter some problems when using hydraulic boarding bridges, as long as these problems are not very serious, we don't have to worry too much. However, when there is a problem with the hydraulic boarding bridge, only a timely solution is the correct response. Below is an introduction to some common faults of the hydraulic boarding bridge and specific solutions: the hydraulic boarding bridge must be repaired while hanging and supporting the working platform of the lifting platform to avoid sudden descent of the lifting platform, causing unnecessary casualties; 2. Do not adjust the overflow valve arbitrarily. Because every component in the hydraulic system operates at a specified pressure once the relief valve is adjusted, it may cause abnormal operation of the hydraulic system, causing unnecessary damage to people, machines, and objects; Non professional personnel are not allowed to disassemble electrical appliances at will to prevent electric shock or incorrect connection.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.
Zhongshan.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.
When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends it can automatically cut off the oil circuit and stop descent
