Description

Elevator without counterweight and its lifting drive motor, drive unit and drive system

technical field

The utility model belongs to the technical field of lifting equipment, and relates to a non-counterweight elevator and its lifting driving motor, driving unit and driving system.

Background technique

Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. According to the speed, it can be divided into low-speed elevators (below 1 m/s), fast elevators (1-2 m/s) and high-speed elevators (above 2 m/s).

Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings today. In 1852, E.G. Otis of the United States developed a safety elevator for wire rope lifting. In the 1980s, the driving device was further improved, such as the motor driving the winding reel through the worm drive, and the use of balance weights. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator. At the end of the 20th century, elevators used permanent magnet synchronous traction machines as power. It greatly reduces the area occupied by the computer room, and has the advantages of low energy consumption, energy saving and high efficiency, and fast lifting speed, which greatly promotes the development of real estate in the direction of super high-rise buildings. Modern elevators are mainly composed of traction machine winches, guide rails, counterweight devices, safety devices (such as speed limiters, safety gears and buffers, etc.), signal control systems, cars and hall doors. These parts are respectively installed in the hoistway and machine room of the building. Steel wire rope friction transmission is usually used. The wire rope goes around the traction sheave, and the two ends are respectively connected to the car and the counterweight. The motor drives the traction sheave to lift the car up and down.

Because the counterweight device is an integral part of the existing elevator, the mechanical parts of this part account for a considerable weight and proportion of the elevator during elevator design, and the counterweight device also occupies a large part of the elevator cost. In order to solve the deficiencies of the existing technology, people have been exploring and proposing various solutions. For example, a Chinese patent document discloses a counterweight-free elevator [Patent No.: CN201817170U], which includes a car, and the car is guided along the The guide rails are lifted and lowered in the hoistway, and the hoistway is equipped with an inverted driving device and a pulley block. The pulley block includes at least one set of movable pulleys, at least one set of fixed pulleys and at least one set of car pulleys. The fixed pulleys are installed on the top of the hoistway, and the movable pulleys are installed At the pull-back end of the pull-back driving device, the car pulley is installed on the car, and one end of the traction rope is fixed on the top of the hoistway, and after winding around the movable pulley, the fixed pulley and the car pulley, the other end is fixedly connected to the top of the hoistway.

The above scheme adopts no counterweight scheme, which reduces the complexity and weight of the elevator, reduces the load-bearing requirements of the traction rope and the pulley block, and reduces the size of the pulley block, which leads to a reduction in the space requirement of the elevator well, so that the building installation cost and use cost of the elevator are greatly reduced. . Moreover, because the pull-back driving device is adopted, the pull-back traction end of the pull-back drive device is always stressed during the upward and downward travel of the elevator car, which ensures the reliable operation of the elevator. But above-mentioned scheme also has weak point, and the driving mechanism of this scheme is pull-type oil cylinder, also is just rod-type oil cylinder, and this oil cylinder is very inaccurate when stroke control, and the stroke of tie-rod type oil cylinder is shorter.
