技术领域 Technical field
本发明涉及一种电梯用钢丝绳组的均力装置的改进，特别是一种 可对六组钢丝绳组的受力进行调节，并使每组钢丝绳组的受力达到相 同的电梯用钢丝绳组的六节点均力装置。 The invention relates to an improvement of a equalizing device for a steel wire rope set for an elevator, in particular to a sixth wire rope set for an elevator which can adjust the force of six sets of wire rope sets and achieve the same force of each set of wire rope sets Node equal force device.
背景技术 Background technique
目前国内外的电梯通常采用曳引机驱动电梯，曳引电梯悬挂提升 系统由曳引轮、 钢丝绳组、 轿厢、 平衡块系统等主要部件组成； 所述 曳引电梯悬挂提升系统中通_过钢丝绳组中的每.根钢丝绳在曳引轮的 槽内缠绕而产生的摩擦力提供轿厢提升或下降的动力；在电梯驱动技 术不断发展的调节下，电梯的提升高度以及行驶速度都有了很大的提 高，同时也对电梯自身的安全性和可靠性提出了更高的要求。理论上， 电梯在使用过程中， 钢丝绳组中的每根钢丝绳的受力应一样， 且曳引 轮上用来缠绕钢丝绳的槽的形状和尺寸也应一祥； 但实际使用过程 中， 由于各种原因会使钢丝绳组中的每根钢丝绳的受力不一样， 这祥 就会造成有些钢丝绳受力大， 有些钢丝绳受力小； 受力大的钢丝绳与 其对应的曳引轮上的槽之间的摩擦力会相对较大，这样会造成其对应 的曳引轮上的槽的摩擦更厉害， 时间一长， 就好造成其对应的曳引轮 上的槽的形状和尺寸发生变化，造成受力大的钢丝绳工作中所受的力 越来越大。 如果曳引轮上的槽磨损后半径减少 0„ 1 毫米， 曳引轮每旋 转一圈， 钢丝绳要少运动 0. 314毫米； 以 20层的楼房为例， 曳引轮 大约要旋转 1 00圏， 那么该跟钢丝绳就要少运动 31 4毫米， 经过试 , 发现该 3艮钢丝绳要多受力约 3000牛； 当钢丝绳组中个钢丝绳的
受力不均时， 受力小的钢丝绳和曳引轮之间产生蠕动现象， 钢丝绳和 曳引轮之间的蠕动会引起钢丝绳和曳引轮的磨损； 楼层越高， 上述情 况更严重。 因而， 长时间使用的受力大的钢丝绳在使用过程中， 容易 断裂， 而造成电梯安全事故； 同时， 受力小的钢丝绳也会因与曳引轮 的磨损， 出现受损， 如果受损严重， 也会引起造成钢丝绳的断裂， 而 造成电梯安全事故； 为此， 我们开发了一种可对六组钢丝绳组的受力 进行调节，并使每组钢丝绳组的受力达到相同的电梯用钢丝绳组的六 节点均力装置。 At present, elevators at home and abroad usually use a traction machine to drive the elevator. The traction elevator suspension lifting system is composed of main components such as a traction sheave, a wire rope set, a car, a balance block system, and the traction elevator suspension system. The friction generated by each wire rope in the wire rope group is wound in the groove of the traction sheave to provide the car lifting or lowering power; under the continuous development of the elevator driving technology, the lifting height and the traveling speed of the elevator have Great improvement, but also put forward higher requirements for the safety and reliability of the elevator itself. In theory, during the use of the elevator, the force of each wire rope in the wire rope set should be the same, and the shape and size of the groove used to wind the wire rope on the traction sheave should also be reasonable; but in actual use, due to For some reasons, the force of each wire rope in the wire rope group is different. This will cause some steel wire ropes to be stressed, and some steel wire ropes have small force; between the steel wire rope with strong force and the groove on the corresponding traction wheel The frictional force will be relatively large, which will cause the friction of the groove on the corresponding traction sheave to be more severe. When the time is long, the shape and size of the groove on the corresponding traction sheave will be changed, resulting in The force of the wire rope work is getting bigger and bigger. If the groove on the traction sheave is worn, the radius is reduced by 0 „1 mm, and the wire rope is rotated by 0.53 mm for each rotation of the traction sheave. For a 20-story building, the traction sheave is about 100 rpm. Then, the wire rope should be less than 3 4 mm. After the test, it is found that the 3 wire rope should be subjected to about 3000 cattle; when the wire rope is in the wire rope When the force is uneven, the creeping phenomenon occurs between the wire rope and the traction sheave with small force. The creep between the wire rope and the traction sheave causes the wire rope and the traction sheave to wear. The higher the floor, the more serious the above situation. Therefore, the long-term use of the heavy-duty steel wire rope is easy to break during use, resulting in an elevator safety accident; at the same time, the wire rope with small force will be damaged due to the wear of the traction sheave, if the damage is serious , it will also cause the wire rope to break and cause the elevator safety accident; for this reason, we have developed a wire rope for elevators that can adjust the force of the six sets of wire rope sets and make the force of each set of wire rope sets the same. The six-node uniform force device of the group.
