Description
Technical Field
The invention relates to the technical field of elevators, in particular to a winding drum, a hoisting mechanism and an elevator.
Background
In recent years, with the rapid development of global economy, science and technology are changing day by day, and the elevator has more and more requirements on civil elevators, construction elevators, fan tower barrel elevators and building tower crane elevators, and has more and more types, various loads, more and more compact structure and great attention on safety performance.
For the elevator with smaller load, a single steel wire rope can meet the requirements of strength and fatigue, but the steel wire rope is not easy to find when fatigue damage occurs, and great property loss and casualties can be caused, so that the absolute safety of the elevator can be ensured by adopting double steel wire ropes even under the condition of small load.
The steel wire rope needs to be guaranteed to be orderly wound on the winding drum, otherwise the steel wire rope is disordered and knotted, and the problems that the elevator is not accurate in stopping the platform and the like are caused. Although the single-layer steel wire rope winding drum can wind double steel wire ropes at the same time, the steel wire ropes can only wind one layer on the surface of the winding drum, and the winding length of the steel wire ropes is limited and cannot meet the requirement. The steel wire ropes on the multilayer steel wire rope reel are multilayer and can be wound on the reel, the requirement of the winding length of the steel wire rope is met, however, the double steel wire ropes conflict in the process of winding and reversing the steel wire ropes layer by layer, and therefore only one steel wire rope can be wound on the multilayer steel wire rope reel. Therefore, the existing solution is to use two multi-layer wire rope drums to reel in and pay off the double wire ropes.
The two traditional winding drums are installed in two ways, namely, the first way is to use two sets of single-winding-drum hoisting mechanisms and realize synchronous winding and unwinding of the steel wire rope by using electric control. The required functions can be realized by arranging two sets of single-reel hoisting mechanisms, the technical difficulty is low, and the popularization is easy. However, the structure needs two sets of motors and winding drums, so that the number of parts is large, the cost is high, the two winding drums are electrically controlled to have synchronism, the synchronism is poor, and the unbalance loading of a single steel wire rope can be caused. In the second type, a single-reel hoisting mechanism uses a coupler to serially connect reels at the reel side. A single-reel hoisting mechanism uses a coupler on one side of a reel and then serially connects another reel, the technical difficulty is low, and the synchronism is better than that of the first mode. But the required machining precision of this mounting means is higher, and occupation space is great, and two wire rope's interval is great moreover, has very big limitation when using occasionally.
