Description

液控盘式刹车装置
本实用新型涉及一种液控盘式刹车装置，适用于石油钻机、修井机、通井机绞车的制动，也可用于其它用途的卷扬机的制动和调速。
传统的石油钻机、修井机、通井机绞车的刹车装置均采用机械带式刹车，存在制动力矩不足、可靠性差；制动效能不稳定、散热差；操作费力、调整、维修不便等问题。刹车装置的性能不仅影响作业时效和生产成本，还关系到人员、设备和油井的安全，带刹车装置一直被认为是最重要也是最薄弱的部件，长期困扰着使用、制造和设计部门。
本实用新型的目的在于提供一种刹车力矩容量大，制动效能稳定、控制灵敏准确、操作省力、安装和维修方便、易于自动控制、安全可靠性高的液控盘式刹车装置。
实现本实用新型目的所采取的技术措施如下：
本使用新型主要由刹车盘，刹车钳及钳架组成，刹车盘与主机绞车滚筒固连，与刹车钳组成刹车副，钳架设置在绞车底座上，用于固定刹车钳。刹车钳包括工作钳和安全钳。
工作钳主要由刹车片分别设置在刹车盘外沿的两侧、和杠杆一端铰接的钳体固连，支杆固连于钳架上，支杆两端沿径向分别经销轴与杠杆槽孔呈滑配合，杠杆可绕销轴转动，两杠杆的另一端分别经销轴与活塞杆、经销轴与油缸相连，油缸盖与油缸固连，活塞杆与油缸呈滑配合，这样，当活塞与油缸相对运动时，通过杠杆带动一副刹车片做张合运动，当在油压力的作用下刹车片贴上刹车盘时，相互之间产生正压力，大小与油缸内的油压力成正比，将绞车刹死，油压卸荷时，在螺旋弹簧力的作用下，活塞复位，即松刹，拉簧一端与固连于活塞杆上销轴的簧钉相连，另一端与固连于油缸上销轴的簧钉相连，两拉簧平行设置在两销轴的两端构成；安全钳主要由刹车片分别设置在刹车盘外沿的两侧、和杠杆一端铰接的钳体固连，支杆固连于钳架上，支杆两端沿径向分别经销轴与杠杆槽孔呈滑配合，杠杆可绕销轴转动，两杠杆的另一端分别经销轴与活塞杆、经销轴与顶杆相连，碟形弹簧组一端与活塞台阶右端靠接，另一端与油缸底部靠接，油缸盖与油缸固连，活塞杆与油缸呈滑配合，顶杆台阶与调整螺母台阶镶嵌，经螺钉与调整螺母底部的垫片固连，调整螺母与油缸外圆呈螺纹连接，以调节顶杆与油缸间的轴向距离，从而调节安全钳的松刹间隙，然后用锁紧螺母固紧构成。工作钳为进油刹车，用于工作制动，安全钳为回油刹车，用于紧急制动和驻车制动，所需工作钳、安全钳的数量依主机负荷确定。当压力油进入油缸腔，使活塞压缩碟形弹簧组，安全钳处于松刹状态；当压力油卸载，松刹间隙迅速消除，安全钳靠碟形弹簧的恢复力来刹车。杠杆(8)采用“十”字型结构，支杆两端放在杠杆中间的槽孔内，使其相互间运动灵活自如，拆装方便。这种结构在满足强度要求前提下，节省材料，减轻重量。且可以保护支杆与杠杆及其与销轴之间的接触面，减少锈蚀，外部造型美观，使用更加方便。
本实用新型的优点是：能够满足正常工作制动及紧急安全制动，具有刹车力矩容量大，制动效能稳定，刹车副动作惯性小，刹车力可调性好，刹车准确灵敏，操作轻便，调整维修方便的特点。

结合附图对本实用新型的结构及实施例说明如下：
本使用新型主要由刹车盘1，刹车钳(2、3)及钳架4组成，刹车盘与主机绞车滚筒固连，与刹车钳组成刹车副，钳架设置在绞车底座上，刹车钳固连于钳架上，刹车钳包括工作钳2和安全钳3，工作钳主要由刹车片5分别设置在刹车盘1外沿的两侧，和杠杆7一端铰接的钳体6固连，支杆8固连于钳架4上，支杆两端沿径向分别经销轴9与杠杆槽孔呈滑配合，两杆杆的另一端分别经销轴12a与活塞杆10、经销轴12b与油缸14相连，油缸盖13与油缸14固连，活塞杆10与油缸14呈滑配合，拉簧15一端与固连于活塞杆上销轴12a的簧钉11a相连，另一端与固连于油缸上销轴12b的簧钉11b相连，两拉簧15平行设置在两销轴的两端构成；安全钳3主要由刹车片5分别设置在刹车盘1外沿的两侧，和杠杆7一端铰接的钳体6固连，支杆8固连于钳架4上，支杆两端沿径向分别经销轴9与杠杆槽孔呈滑配合，两杠杆的另一端分别经销轴17a与活塞杆16、经销轴17b与顶杆24相连，碟形弹簧组19一端与活塞杆台阶右端靠接，另一端与油缸20底部靠接，油缸盖18与油缸20固连，活塞杆16与油缸呈滑配合，顶杆24台阶与调整螺母22台阶镶嵌，经螺栓与调整螺母底部的垫片23固连，锁紧螺母21、调整螺母22与油缸20外圆呈螺纹连接构成。
工作钳的工作原理是，压力油从进油口充入油缸腔，活塞与油缸作相对运动，从而推动两端的杠杆使一副刹车片相向运动，抱住刹车盘，实现刹车。油压越大，刹车力矩也越大；油压趋向零时，在拉簧的拉力作用下，刹车片与刹车盘脱离，工作钳处于松刹状态。
安全钳的工作原理是，压力油从进油口充入油缸腔，活塞与油缸作相对运动，压缩碟形弹簧，从而拉动两端的杠杆使一副刹车块相对张开，此时安全钳处于松刹状态；当压力油卸荷时，被压编的碟形弹簧恢复力通过杠杆推动刹车块，使之抱住刹车盘，此时安全钳处于刹车状态。可以通过调节螺母来调整松刹间隙的大小，补偿刹车块磨损量。工作钳、安全钳的工作状态相反，组成一个复合式刹车系统，形成安全互锁的双重刹车机构，确保整个刹车系统安全可靠。
