MishkoltzElectEvery theater is a public place with a large number of people, 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.
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.
Mishkoltz.That's all for a brief introduction to the common types of electric elevators. I hope everyone can have a better understanding of this product. Currently, this product is selling well in China,MishkoltzElectric tatami elevator, as many places need to use this type of product that has both lifting function and flexible movement. Companies specializing in producing this type of product are now promoting it on a large scale through the internet, Friends in need can directly find the corresponding companies on the internet and have a brief understanding of the models, performance, and price information of these products. They can purchase directly through the internet.
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.
.Then,MishkoltzSimple electric elevator, 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.
Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door
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.
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar, remove any obstacles or debris near the electric elevator that may hinder operation, and check whether the operating handle can be used normally.
To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, the safety distance can be 0.40m.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
Executive standard.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.
Greater than 0.04s; When the hydraulic buffer is used, the oil level shall be checked, and the action of the hydraulic buffer shall be monitored by the Electrical safety switch. When the hydraulic buffer is compressed, the cage shall not
The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver,MishkoltzElectric one ton elevator, the landing door shall not be opened.
Mishkoltz.During the use period, the door may not meet the above requirements and record the inspection results.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, but safety should be maintained.
