Description

A kind of elevator installation construction method

technical field

The invention relates to a traction elevator, in particular to an elevator installation and construction method.

Background technique

An elevator is a lifting device that serves several specific floors in a building and operates intermittently in the vertical direction to transport passengers or goods. The concept of elevators in a broad sense includes passenger-cargo elevators, escalators, moving walks, etc. Elevators in a narrow sense refer to vertical or slightly inclined lifting equipment that serve specified floors and have cars, excluding escalators and moving walks.

The technical development of elevators can be roughly divided into the following stages:

Before the 18th century, the principle of lifting was used to lift heavy objects driven by human power. Around 1100 BC, the ancient Chinese invented the potter's wheel, which uses the rotary motion of the reel to increase the height of objects. In 236 BC, the Greek mathematician Archimedes designed the human-driven drum hoist, which is considered to be the originator of modern elevators.

18th century - 1889 Mechanically powered elevator. In 1743, Louis XV of France authorized the installation and use of personnel lifts in his private palace in Versailles. In 1852, Elisha Graves Otis, a mechanical engineer in Yonkers, New York, USA, invented the world's first safety elevator and demonstrated the invention at the 1854 New York World's Fair. In 1862, the Otis company came out with an elevator controlled by a separate steam engine.

1889-early 20th century: The mature development of the elevator. In December 1889, the Otis Elevator Company of the United States successfully installed the world's first electric drive elevator in the Demarest Building in New York. And lift the car, and a veritable elevator was born from then on. In 1892, Otis Corporation of the United States began to adopt the button control device to replace the traditional control method of pulling the rope in the car, which pioneered the modernization of the control method. In 1922, Otis Company manufactured the world's first modern escalator, which was combined with horizontal wedge-groove steps and comb plates, and has been used by other escalator manufacturers since then.

From the beginning of the 20th century to the present: the development of diversification and high performance of elevators.

At present, in order to meet the various needs of people and improve the functions of products, the types of elevators are constantly developing towards diversification. In 1985, Mitsubishi Electric Corporation developed a spiral escalator running in a curved line and successfully put it into production. The spiral escalator can save architectural space and has decorative artistic effects. In March 1996, the Finnish KONE Elevator Company released an innovatively designed machine room-less elevator, which eliminates the need for an independent machine room and reduces construction costs. In the late 1990s, Fuji-tec developed a variable-speed moving walkway, that is, the moving walkway runs at a segmented speed, which improves the safety of passengers when getting on and off the moving walkway, and shortens the time taken for long journeys. In May 2008, Shanghai World Financial Center installed a double-deck car elevator with automatic adjustment of floor spacing.

With the high-rise development of urban buildings, the elevator is forced to develop at a high speed. In July 1976, Fujitec Corporation of Japan developed a DC gearless traction elevator with a speed of 10.00m/s. In 2004, the Taipei International Finance Center Building installed a super high-speed elevator with a speed of 16.8m/s from Japan's Toshiba Elevator Company. The elevator speed used in the Burj Khalifa completed in 2010 is 17.5m/s. The Shanghai Tower, which is planned to be completed in 2014, uses 106 Mitsubishi elevators, 3 of which have a maximum uplink speed of 18 m/s and a maximum downlink speed of 10 m/s.

The safe, efficient and comfortable operation of the elevator is inseparable from the control level of the elevator. Drive control: Experienced in DC motor drive control, AC single-speed motor drive control, AC double-speed motor drive control, AC voltage regulation and speed regulation drive control, AC variable voltage variable frequency speed regulation drive control, AC permanent magnet synchronous motor frequency conversion speed regulation Drive control and other stages. With the development of urban buildings, the importance and requirements of elevators are getting higher and higher, which promotes the development of elevator technology towards safer, low-cost, large-capacity, high-speed, energy-saving, intelligent, and environmental protection.

Elevator construction technology is an important factor that determines the cost, quality and safety of elevator installation, and is also an important link to ensure the normal and safe operation of elevators. Elevator construction technology is closely related to elevator products. The main development and changes of elevator construction technology include the following points:

(1) From scaffolding installation to non-scaffolding installation. It can improve construction efficiency, save construction materials, and improve the safety of construction operations. There are usually scaffold-free installation methods such as self-guided installation and cage installation.

(2) Improvement of measurement methods. With the development of high-speed elevators, the requirements for the measurement accuracy of shafts, guide rails and equipment are gradually increasing. For example, the use of various new track calibration tools can improve the accuracy and efficiency of track calibration.

(3) Adjustment of the working surface. With the increasing workload of elevators and the increase of labor costs, the construction process gradually changed from sequential construction to parallel construction. The cross work caused by parallel construction has new requirements for the construction technical scheme.

(4) Extension of construction technology. With the improvement of elevator functions, more new equipment is involved in the installation of elevators, such as: new intelligent system equipment for elevators, air conditioning equipment, Bluetooth equipment, film and television equipment, etc.

(5) Updating of construction technology. For new types of elevators such as machine room-less elevators, multi-car elevators, and ultra-high-speed elevators, it is necessary to study the installation technology and prepare new construction plans for the products to meet the installation requirements and relevant specifications of the products.

(6) The selection of the overall installation and assembly scheme. According to different occasions and product models, select the appropriate assembly scheme to improve construction efficiency and reduce costs.
