JinyuanDingli The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.
The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
Jinyuan.The pressure joint between the pipe joint and the rubber hose fails prematurely, causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.
Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
.Setting requirements: The landing door should be standardized and tooled.
Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion, Terrace, Tower, Pavilion; Ideal props.
From the above comparison it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
Before use, we should observe whether there is any damage to the electric elevator. We can conduct a no-load test to raise and lower it. If there are any damaged parts, they should be replaced in a timely manner to prevent major accidents.
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,JinyuanElectric elevator, whether there is a lack of hydraulic oil, and whether the oil cylinder is leaking. It is necessary to clean the lifting frame,JinyuanLEGO Electric Elevator, scissors, wiring, it should be designed and calculated separately.
The scaffolding of the parking platform should be laid tightly and firmly.
Use floor doors and cage door devices on construction sites where conditions permit.
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.
equipment maintenance .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, and the lifting of goods should try to maintain a stable and uniform speed.
The downward movement of the hydraulic cylinder (i.e. heavy object lowering). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve,JinyuanElectric belt elevator, hydraulic control one-way valve, energy-saving valve, and explosion-proof electric valve
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Jinyuan.The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
To meet the needs of stage craftsmanship and layout; Product; In the music and dance theater stage arranged in a zigzag pattern, auxiliary lifting platforms are often arranged in front, back, left, and right of the main stage lifting platform. The side and rear auxiliary lifting platforms are used for the smooth opening of the side platform and rear vehicle turntable, ensuring the safety of the cast members.
Stage equipment safety door. To prevent personnel from extending their heads so that the entire platform does not have a height difference, 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.
