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.
Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.
Yuci.Installation position of upper limit switch: Under normal working conditions, the distance between the upper limit switch and the upper limit switch is 0.15m for SC type construction electric elevators, and 0.15m for SS type construction electric elevators (person)
In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, stage machinery is particularly important on the stage. On the stage, 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 design and choreographers meeting the needs of stage craft layout, creating special atmosphere and effects, and changing the stage form according to the needs of the performance.
.Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.
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, stable operation, 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,YuciElectric mobile hydraulic elevator, it can be stopped arbitrarily within the range of travel.
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.
Protective measures should comply with regulatory requirements.
Non automatic reset upper and lower limit switches should be installed at both the upper and lower ends of the stroke, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers),
High lifting height, using side mounted oil cylinders stable operation, noise free, easy maintenance, and longer service life.
Administration.Every theater is a public place with a large number of people, 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.
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 intermediate stage, a T-shaped stage, or a hall.
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.
Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, strength, stability, etc.,YuciElectric small elevator, and the production should meet the design requirements.
The cheapest.It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier
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.
The landing door should meet the requirements of the specifications and achieve standardization.
Yuci.Work is essential, and the main protective accessories include safety belts, protective covers, platforms and stairs, etc.
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected
