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.

When the rope needs to be paid off, the drum 100 is driven to rotate reversely by external input power, the steel wire rope 500 starts to release on the drum 100 in a forward direction, meanwhile, when the steel wire rope 500 passes through the pulley 620 on the swing link 610, a deflection force in a corresponding direction is generated on the swing link 610, so that the swing link 610 correspondingly deflects along the releasing direction of the steel wire rope 500 on the drum 100, as the rope paying off of the steel wire rope 500 is carried out, the winding number of turns of the steel wire rope 500 is reduced, the direction deflection change of the steel wire rope 500 passing through the swing link 610 also synchronously occurs, when the steel wire rope 500 is released to the limit position on one side of the drum 100, the steel wire rope 500 starts to release on the drum 100 in a reverse direction under the influence of the deflection force generated by the self-space limitation of the steel wire rope 500, the swing link 610 correspondingly deflects along the releasing direction of the steel wire rope 500 on the drum 100, and then continues until the steel wire rope 500 is released to the limit position on the other side of the drum 100, the rope paying off direction change with the same mechanism as the above process occurs again, and the steel wire rope 500 is sequentially and circularly lowered until the rope releasing action of the steel wire rope is completed.

In this embodiment, the wire rope 500 may be a wire rope, a string, or a chain.

In one embodiment, the swing link 610 is further connected to the frame 300 through the first elastic member 640, and in the process that the swing link 610 rotates a certain angle around the rotation axis, the first elastic member 640 is stretched or compressed, and then the swing link 610 is driven to rotate by the restoring force generated when the first elastic member 640 contracts or expands, so as to return to the original position, thereby realizing that when the rope 500 is wound or unwound to one end of the winding drum 100 and needs to be reversed, the direction adjustment can be performed in time, avoiding error expansion, and improving the rope arrangement quality.

In one embodiment, the first elastic members 640 are symmetrically disposed on two sides of the swing link 610, that is, when the swing link 610 is at the original position, the first elastic members 640 are inclined at a certain angle with respect to the swing link 610, after the swing link 610 swings at a certain angle toward the direction of the first elastic member 640 on one side, the first elastic member 640 is compressed, the first elastic member 640 on the other side is extended, and then the first elastic member 640 on the other side is extended and restored, and the first elastic member 640 on the other side is contracted and restored, so that the restoring force drives the swing link 610 to swing toward the direction of the first elastic member 640 on the other side and restore to the original position. The arrangement of the two first elastic members 640 can ensure the stress balance and the swing stability of the swing link 610, and ensure that the swing link 610 receives the elastic force and the restoring force of the first elastic members 640 with the same magnitude in the process of angle swing and restoration at both sides of the swing link 610.
