JiningInstallation of electric elevators for fire protectionWhat to pay attention to when buying

When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.

According to the needs of different performance genres, the form of the stage can be changed. For example, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage, a T-shaped stage, or a hall.

Jining.Is there a relevant rule requirement for the cleanliness of hydraulic stations?

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).

.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

Setting requirements: Each landing entrance should be equipped with a landing door,JiningOutdoor electric lifting platform, which should cover the opening with its full width, and should not open towards the lifting passage.

The net height of the landing door opening should not be less than 8m, 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, 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.

When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.

The up travel (limit) switch should be of the automatic reset type.

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,JiningFolding electric elevator, 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.

average method.Double layer steel mesh: The diameter of the steel bars is 12mm, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops

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.

Quality improvement.In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, there are suspension rods, suspension points, lighting bridges, lighting suspension cages, and fire curtains. Under the stage, there are lifting platforms, car platforms, turntables, and lifting orchestras. Some lifting platforms are equipped with turntables, or there are lifting platforms in the turntables. Various types of lifting platforms are equipped in professional opera houses, dance theaters, drama theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery, meeting the needs of stage craft layout, meeting the needs of stage design and choreographers, creating special atmosphere and effects, and changing the stage form according to the needs of the performance.

If the set screw is loose, be sure to pin it tightly to prevent accidents caused by the shaft pin falling off. Hydraulic oil should be kept clean and replaced every 6 months.

Setting requirements: For construction electric elevators with foundations installed on roof slabs floors, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.

Jining.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.

Chain type electric lifting mechanism: With a good guiding mechanism,JiningElectric elevator lifting 10 meters, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.

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, 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.
