XinleElectric Protective measures should comply with regulatory requirements.
The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, soft scenery, etc.
Xinle.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
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.
.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.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
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. The throttle valve regulates the flow rate and the ascending and descending speed.
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.
Safety and health.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
Emergency manual valve: In case of power failure it can cause the car to descend to the nearest floor position and open the door
Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.
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.
reform.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 door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, 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
The function of the lifting platform in a theater is roughly as follows: the main lifting platform arranged in the main performance area of the stage is mainly used to quickly change the scenery. Typically,XinleElectric tatami elevator, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform, and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.
When the door is closed,XinleElectric pulley elevator,XinleElevator electric 6 meters, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.
