Description

一种升降电梯用平衡补偿缆的生产线 技术领域
本发明涉及补偿链生产技术领域，尤其涉及一种升降电梯用平衡补偿缆的生产线。
背景技术
当前，市场上运用的升降电梯大多为曳引式电梯，曳引电梯包括轿厢、曳引钢丝绳、对重及随行缆线。电梯在运行过程中，轿厢侧和对重侧的钢丝绳的长度在不断变化，从而引起曳引轮两侧钢丝绳重量的变化，为此，当电梯的提升高度超过一定高度时，必须要设置具有一定重量的部件来平衡因高度变化带来的重量变化，这就是电梯平衡补偿链。简而言之，电梯平衡补偿链定义为：用于连接电梯的轿厢与对重，平衡曳引绳及随行缆线的重量，对电梯的运行起平衡作用的部件。要求其具有承载负荷大，运行噪声小，单位长度重量等特点。
目前市面上的电梯补偿链有以下几种：
1、穿绳补偿链，是最原始的一种补偿链，只能用于梯速1.75m/s以下的电梯。具体采用电焊锚链中穿一根剑麻绳，以消除产品升降过程中的噪音。
2、包塑补偿链，为了减小穿绳补偿链在运行过程中的噪音，同时减缓环境对铁链的腐蚀，于是在穿绳补偿链的基础上包裹一层塑料套，形成了包塑补偿链。具体的，采用钢丝绳作为拉伸强力骨架，外面包裹高分子材料或PVC材料。
3、全塑补偿链，可用至6m/s的高速电梯，外表为缆状PVC结构，使用时电梯运行能达到平稳静音的效果。具体的，采用电焊锚链外裹PVC塑料，通过挤出成型的方法生产。
4、采用电焊锚链外包裹橡胶及纤维，通过模压成型橡胶硫化方式生产。
如中国专利CN1455131A公开了电梯平衡补偿链，包括铁链、橡胶柱体、纤维层，上述铁链置于上述橡胶柱体内，上述橡胶柱体裹有纤维层。该发明专利还公开了制造电梯补偿链的方法，包括步骤：A、除锈：铁链去毛刺、除锈处理；B：制片状胶料；C：制橡胶柱体：将上述铁链置于挤出机的“T”型模具内，在将上述片状胶料，送入挤出机，挤出的温度为30-90℃，挤出的牵引速度为3-11米/秒，挤出机将上述胶料挤出，挤压到上述“T”型模具内，包裹于铁链上，制 成橡胶柱体，使上述铁链置于橡胶柱体内；D：制纤维层；E：硫化。
又如中国专利CN105440330A公开了一种无卤环保电梯平衡补偿链的制造方法，包括除锈、制片状胶、制胶层和硫化步骤，其特征在于：制片状胶的具体步骤为：将原料按照如下加料顺序：先将配量比的天然橡胶和三元乙丙胶投入炼胶机先进行塑炼，在140～160℃的密炼温度下，辊距为2～5mm，塑炼5min，在炼胶机上通过2～3次后，包辊，随后依次加入配量比的乙烯-辛烯-戊烯共聚物、马来酸酐接枝乙烯-醋酸乙烯酯共聚物、马来酸酐接枝乙烯-辛烯共聚物、马来酸酐接枝乙烯-丁烯共聚物、高密度填充料、环氧大豆油、润滑剂和阻燃剂，薄挤均匀，制成片状胶。其中，所述制胶层的具体步骤为：将制得的片状胶料投入挤出机的模具中，设置挤出机的进料段温度为110-120℃，挤出机出料段的温度为120-150℃，将上述片状胶料挤压到模具内，并包裹于铁链表面，构成环形橡胶层，控制橡胶层径向厚度为2～2.5mm。
上述公开的两个发明专利披露的技术方案，其关键技术主要是原材料的选用，以提高平衡补偿链的各项性能，但是，目前工艺技术的生产效率大多不是很高，且在制造过程中均采用水平牵引方式，因此，难以消除产品成型中产生的产品扭曲等问题。

如图1所示，竖井式或塔式布局的生产线从上至下依次包括：供料单元1、挤出单元2、冷却单元3及包装单元4，供料单元1与挤出单元2连接，挤出单元2与冷却单元3连接，挤出单元2位于冷却单元3上层，冷却单元3与包装单元4连接，冷却单元3位于包装单元4上层。作为优选的，供料单元1包括电焊锚链供料单元11及弹性材料供料单元12。
作为进一步优选的，在本发明的此实施方式中，电焊锚链供料单元11位于挤出单元2上层，即位于平衡补偿缆生产线本体10的顶层；电焊锚链供料单元11下方布置挤出单元2；在本发明的此实施方式中，电焊锚链供料单元11包括 牵引机及控制器，挤出单元2为挤出机。首先采用牵引机将检验合格的电焊锚链提升至设定的高度，即提升至平衡补偿链生产线本体10顶部位置，然后采用控制器，将电焊锚链送入位于电焊锚链供料单元11下层挤出单元2挤出机的模具中。作为更进一步优选的，在挤出单元2的同层还设有弹性材料供料单元12，在本发明的此实施方式中，弹性材料供料单元12为升降机或真空输送机，在这里以真空输送机作为弹性材料供料单元12为例加以说明，采用真空输送机式的弹性材料供料单元12将高分子弹性材料送入挤出单元2的挤出机颗粒料入口，控制挤出温度在95℃-130℃之间，挤出的牵引速度为3-11米/秒，而在本发明的此实施方式中，控制挤出温度为95℃，挤出的牵引速度为3米/秒，挤出单元12的挤出机将上述高分子弹性材料挤出，挤压到挤出机的模具内，包裹于电焊锚链外周，制得橡胶柱体。
作为再进一步优选的，冷却单元3包括一次冷却单元31及二次冷却单元32。一次冷却单元31位于挤出单元2下层，一次冷却单元31为快速冷却单元，因此，在本发明的此实施方式中，一次冷却单元31为强风冷却装置。一次冷却单元31下方为地面水平层，地面水平层包括与一次冷却单元31出口处连接的补偿链导向出口311，补偿链导向出口311具有过度改线作用，将垂直布局的平衡补偿链生产线本体10过度至水平方向，地面水平层上还包括有二次冷却单元32及包装单元4，二次冷却单元32的入口与补偿链导向出口311的出口端连接，包装单元4则与二次冷却单元32连接。作为优选的，二次冷却单元32为冷却水槽。采用双层冷却方式，结合补偿链的垂直牵引状态，很好地消除产品扭力及缠绕状态。

图2示意性地显示了本发明第一种实施方式提供的一种升降电梯用平衡补偿缆的生产线。
如图2所示，本发明第二种实施方式提供的一种升降电梯用平衡补偿缆的生产线包括平衡补偿链生产线本体10。如图2所示，平衡补偿链生产线本体10为垂直于地面的竖井式布局生产线，或为垂直于地面的塔式布局生产线，其与水平布局生产线相比，优点在于：取消了水平生产线的牵引装置，因此，避免产生因牵引受力不均而产生的应力问题；同时，竖井式或塔式布局的生产线收重力作用向下牵引，因此节约了牵引动力；另外，补偿链处于垂直状态，因此，很好地消 除了产品扭力及缠绕状态。
作为本发明的一个发明点，其与实施例1的不同在于：如图2所示，竖井式或塔式布局的生产线从上至下依次包括：供料单元1、挤出单元2、冷却单元3及包装单元4，供料单元1与挤出单元2连接，挤出单元2与冷却单元3连接，挤出单元2位于冷却单元3上层，冷却单元3与包装单元4连接，冷却单元3位于包装单元4上层。作为优选的，供料单元1包括电焊锚链供料单元11及弹性材料供料单元12。
作为优选的，在本发明的此实施方式中，弹性材料供料单元12位于挤出单元2上层，即位于平衡补偿缆生产线本体10的顶层；弹性材料供料单元12下方为电焊锚链供料单元11，即电焊锚链供料单元11位于上方第二层，电焊锚链供料单元11下方为挤出单元2，机挤出单元2位于上方第三层。在本发明的此实施方式中，弹性材料供料单元12为升降机或真空输送机，在这里以升降机作为弹性材料供料单元12为例加以说明，首先采用升降机式的弹性材料供料单元12将高分子弹性材料送入挤出单元2的挤出机颗粒料入口，同时采用牵引机将检验合格的电焊锚链提升至设定的高度，即提升至平挤出单元2上方入口位置，然后采用控制器，将电焊锚链送入位于电焊锚链供料单元11下层挤出单元2挤出机的模具中，然后将上述高分子弹性材料挤出，挤压到挤出机的模具内，包裹于电焊锚链外周，制得橡胶柱体，在此过程中，控制挤出温度在95℃-130℃之间，挤出的牵引速度为3-11米/秒，而在本发明的此实施方式中，控制挤出温度为130℃，挤出的牵引速度为11米/秒。
作为再进一步优选的，冷却单元3包括一次冷却单元31及二次冷却单元32。一次冷却单元31位于挤出单元2下层，一次冷却单元31为快速冷却单元，因此，在本发明的此实施方式中，一次冷却单元31为强风冷却装置。一次冷却单元31下方为地面水平层，地面水平层包括与一次冷却单元31出口处连接的补偿链导向出口311，补偿链导向出口311具有过度改线作用，将垂直布局的平衡补偿链生产线本体10过度至水平方向，地面水平层上还包括有二次冷却单元32及包装单元4，二次冷却单元32的入口与补偿链导向出口311的出口端连接，包装单元4则与二次冷却单元32连接。作为优选的，二次冷却单元32为冷却水槽。采用双层冷却方式，结合补偿链的垂直牵引状态，很好地消除产品扭力及缠绕状态。
实施例3：
本发明第三种实施方式提供的一种升降电梯用平衡补偿缆的生产线包括平衡补偿链生产线本体10。平衡补偿链生产线本体10为垂直于地面的竖井式布局生产线，或为垂直于地面的塔式布局生产线，其与水平布局生产线相比，优点在于：取消了水平生产线的牵引装置，因此，避免产生因牵引受力不均而产生的应力问题；同时，竖井式或塔式布局的生产线收重力作用向下牵引，因此节约了牵引动力；另外，补偿链处于垂直状态，因此，很好地消除了产品扭力及缠绕状态。
作为本发明的一个发明点，同座井道或塔道中布局多条平衡补偿缆生产线本体10，平衡补偿缆生产线本体10为上述实施例1或实施2中的任何一种形式的平衡补偿缆生产线本体10，或同时包括实施例1及实施2中的两种形式的平衡补偿缆生产线本体10，以此提高生产效率。
综上所述，本发明提供的一种升降电梯用平衡补偿缆的生产线，取消了水平生产线的牵引装置，因此，避免产生因牵引受力不均而产生的应力问题；同时，竖井式或塔式布局生产线收重力作用向下牵引，因此节约了牵引动力；采用双层冷却设置，且补偿链处于垂直状态，因此，很好地消除了产品扭力及缠绕状态；另外，采用快速一次成型技术，确保产品品质，减少大量的能源消耗。
