具体实施方式
下面结合附图对本发明作进一步详细的说明。
图1示意性地显示了根据本发明的一种实施方式的一种用于曳引式建筑施工升降机的补偿链装置，图2显示了图1中的端接装置的结构，图3显示了图2中的扣体的结构，图4显示了图2中的套筒的结构，图5显示了图2中的固定销的结构。如图1-5所示，该装置主要为一个重量补偿体，其由端接装置1和至少一个条状补偿单体2相连接组成，而在将重量补偿体应用到升降机设备中时，其一端与曳引机所拉动的吊笼相连接，另一端则与对重相连接。其中，而升降机通过天梁和绕线轮组改变曳引机的曳引媒介方向能够拉动吊笼上下移动，曳引媒介为钢丝绳或钢带，并且天梁能够升降移动
端接装置1优选为吊环、U形环或者线圈等，其主要包括一个扣体3，扣体3一般是由金属等硬质材料制成，其大致呈环状，两端为弧形，中部则为直形。而在扣体3的其中一个直形边上设置有一个缺口31，而在缺口31处套设有一个中空的套筒4。
其中，在套筒4的内部设置有内螺纹，而在缺口31两侧的两个末端上均设置有于该内螺纹相配合的外螺纹，即在扣体3上位于缺口31两侧的两个末端均与套筒4螺纹连接。而在使用工具将扣体3进行一定的弯折的情况下，能够方便地将套筒4从扣体3上拆下。
此外，扣体3和套筒4还被一根固定销5贯穿固定。其中，在扣体3的位于缺口31侧面的其中一个末端上设置有一个贯通的内通孔32，而在套筒4的相应位置的侧壁上设置有两个相对的外通孔41，内通孔32与外通孔41的尺寸一般相同，当将套筒4套设连接在扣体3上时，个外通孔41和内通孔32位于同一直线上，则固定销5能够贯穿各外通孔41和内通孔32，从而将扣体3和套筒4进行进一步固定。
固定销5的中部为长条形并且伸入到各外通孔41和内通孔32的内部，其中，固定销5的其中一端设置有一个环扣51，环扣51的尺寸大于其中部尺寸，同时也大于外通孔41和内通孔32的尺寸，因此环扣51不会伸入到到外通孔41和内通孔32中而导致固定销5滑落，能够对该端进行固定；而固定销5的另一端分为两条向不同方向延伸的分叉52，而两条分叉52的总尺寸一般不大于固定销5中部的尺寸，则两条分叉52不仅能够对其所在的端进行固定，在必要时还可以受外力合并在一起，然后从外通孔41和内通孔32中穿过，从而能够顺利地从取出固定销5，方便对端接装置1进行拆卸。
条状补偿单体2优选为链条、钢丝绳、补偿缆和钢带等。其中，条状 补偿单体2可以选择设置成能够分为多段，并且各段之间通过端接装置1连接，以共同组成重量补偿体；而条状补偿单体2还可以选择为一体设置的整条，其可以与端接装置1的其中一端相连接，或者两个条状补偿单体2分别与端接装置1的两端相连接，从而共同组成重量补偿体。
而在升降机设备安装该重量补偿体时，如果在端接装置1的两端均连接有条状补偿单体2，则可以将各条状补偿单体2分别与吊笼和对重相连接；而如果仅在端接装置1的其中一端连接有条状补偿单体2，则可以将该条状补偿单体2还与对重相连接，而端接装置1的另一端则与吊笼相连接。
本发明中的用于曳引式建筑施工升降机的补偿链装置通过使用能够方便拆分的端接装置和条状补偿单体连接形成重量补偿体，能够调整对重和吊笼的底部之间的连接长度，以适应两者在相对运动中出现的各种情况，不仅使升降设备能够更加顺利地运行，还保障了设备的运作安全。
以上所述的仅是本发明的一些实施方式。对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
