The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
Every theater is a public place with a large number of people,FenyangManned electric elevator, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
Fenyang.Attention should be paid to the occurrence of oil leakage on the aluminum alloy lifting platform to avoid secondary damage caused by a shortage of hydraulic oil. Overloading work is prohibited during use
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
.The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.
Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.
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, strength testing report.
Is the water cooling and air cooling of the hydraulic station the same?
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, effective protective measures should be taken.
Scheme customization.Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs etc.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example, using the low-speed descent of the lifting platform to represent a sunken ship in the sea using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.
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 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, and the lifting of goods should try to maintain a stable and uniform speed.
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, machines, and objects; Non professional personnel are not allowed to disassemble electrical appliances at will to prevent electric shock or incorrect connection.
Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.
Fenyang.Setting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, stable operation, low noise,FenyangElectric belt elevator, 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.
