JiningMicro elThe bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
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,JiningElectric elevator, 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, while the front auxiliary lifting platform is used to place the rear vehicle turntable near the platform entrance. The leveling lifting platform below the side platform and rear vehicle turntable can be used to level the platform after the side platform or rear vehicle turntable is driven out, so that the entire platform does not have a height difference, ensuring the safety of the cast members.
Jining.The detailed reason why water cannot be used to flush the hydraulic station is that doing so will corrode the oil tank in the hydraulic station, and once water is mixed in the hydraulic station, the damage to the hydraulic system is very large. Therefore, it will simply form pipeline corrosion, water vaporization, and other phenomena that can cause adverse effects or results for hydraulic electric elevators. Therefore it is necessary to prevent such actions to ensure the normal operation and service life of the hydraulic station.
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, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, 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.
.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.
Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
Low power consumption: When the hydraulic guide rail lifting platform descends, it is driven by the pressure generated by its own weight greatly saving energy and reducing consumption.
The down travel (limit) switch should be of the automatic reset type.
Use floor doors and cage door devices on construction sites where conditions permit.
Packaging strategy.Setting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.
Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.
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.
From the above comparison,JiningElectric fork lift table, 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.
Superior quality.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.
8m； When the lifting speed is greater than 0.8m/s, after the upper limit switch is triggered by the hanging cage, the upper small safety distance L should meet the following requirements: L=8+0.1V2,JiningElectric vertical elevator, where L is the upper safety distance; V: Increase speed
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.
Jining.In addition to ground protective fences, a half height middle crossbar and a toe board at least 150mm above the ground.
Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
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, 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.
