Description
Technical Field
The invention relates to the technical field of elevators, in particular to an elevator internet intelligent control system.
Background
An elevator is a permanent transport device serving a number of specific floors in a building, the cars of which travel in at least two rigid tracks perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. According to the speed, the elevator can be divided into a low-speed elevator (below 4 m/s), a high-speed elevator (4-12 m/s) and a high-speed elevator (above 12 m/s). The hydraulic elevator begins to appear in the middle of the 19 th century and is still applied to low-rise buildings until now. In 1852, e.g. austs in the united states developed a safety hoist for wire rope hoisting. In the 80 s, further improvements were made to the drive means, such as motors driving the winding drum via a worm drive, the use of counterweights, etc. At the end of the 19 th century, friction wheel transmission is adopted, and the lifting height of the elevator is greatly increased. The elevator adopts a permanent magnet synchronous traction machine as power at the end of the 20 th century. The machine room occupation is greatly reduced, the energy consumption is low, the energy is saved, the efficiency is high, the lifting speed is high, and the like, and the development of real estate to the direction of an ultra-high layer is greatly promoted.
The compensation chain is generally used on the elevator, has a structure that an iron chain is wrapped by a PVC rubber composite material and is used for compensating the weight of a steel wire rope, so that the elevator runs stably. When the elevator is on the top floor, the steel wire rope is on the counterweight side, and the weight of the steel wire rope is increased on the counterweight side; when the elevator is at the bottom floor, the wire ropes are on the car side, which adds to the weight of the wire ropes. The fall can be balanced by the compensation chain, and the compensation chain is used for compensating dynamic balance, because the steel wire rope has weight and can generate dynamic unbalance along with the continuous up-and-down motion of the elevator.
One end of the compensation chain is connected with the bottom of the counterweight, and the other end of the compensation chain is connected with the bottom of the car. The compensating chain will run in synchronous reversal with the elevator on the counterweight side and the car side and will naturally complete the reversal at the pit (the lowest point of the compensating chain must be kept at a satisfactory distance from the pit floor). In the case of a perfect compensation chain, the reversal of its lowermost end is a smooth running arc. And the two sides of the counterweight and the car run in a straight line; when the silencing rope or the outer plastic of the compensation chain is damaged, when the damaged part runs to the reverse position of the pit, the stress condition of the damaged part is obviously different from that of other normal parts, so that the circular arc of the damaged part can be changed to generate traction force, and the two sides are pulled by the damaged part to swing. As the breakage increases, the swing increases. The car is slightly rocked to cause unstable running, and the compensation chain strikes the wall of the car to send out serious impact sound to cause panic of passengers. The heavy compensation chain can be wound with the protruding devices of the equipment such as the car, the counterweight, the hoistway, the pit and the like to generate serious safety accidents.
Although present elevator has possessed internet intelligent control's function, not only can be more humanized serve the user, can effectively detect the various trouble of elevator simultaneously, and in time investigate and guarantee the safety and the steady operation of elevator, but the damaged detection degree of difficulty of compensation chain is great, because its damage is generally not obvious enough, the staff relies on the naked eye to be difficult to in time discover, and general equipment also is difficult to carry out automated inspection to the damage, consequently the damage can appear often and can't in time be investigated and examined, cause the damage to aggravate finally to exist the risk that leads to the elevator accident.
