Description

卷扬加压控制装置及其控制方法和旋挖钻机 技术领域
本发明涉及工程机械控制领域，特别涉及一种卷扬加压控制装置及其控制方法和旋挖钻机。
背景技术
旋挖钻机是一种现代化的施工机械，主要用于铁路、桥梁、建筑工程中的成孔作业。旋挖钻机其中一种加压形式为卷扬加压，卷扬加压机型主要针对下套管工况而设计，具有加压行程长，加压力大，起拔力大的特点。卷扬加压可以减少作业对设备的振动和冲击，同时可以满足钻机在下套管等工况中所需要的大压力、大行程的要求。
卷扬加压机型旋挖钻机加压力往往大于主卷提升力，在旋挖钻机工作过程中，当钻头尚未到达孔底，而动力头加压键与钻杆提前锁止，如果此时操作加压动作，将会使加压力完全作用于钻杆上，从而由钢丝绳传递到旋挖钻机的主卷扬。由于加压力大，再加上钻杆本身的自重，将会使主卷扬承受远大于它自身能力的负载，此时会导致钻机的主卷扬结构损坏、主卷卷筒安装螺栓断裂等，造成损失，并且给旋挖钻机施工带来危险。

在一个示例性的实施例中，控制器9可以选用TTC60控制器。传感器8可以选用销轴传感器，销轴传感器可以安装于钻机鹅头主卷滑轮处，用于检测主卷提升力，并可以输出相应的电信号，该电信号可以是电压信号或电流信号。供电装置2可以是蓄电池。参考图1，供电装置2的负极通过电源开关1接地，供电装置2的正极连接控制器9的电源端、显示器3的电源端和传感器8的电源端81，供电装置2的正极同时连接加压选择开关6的一端61和加压卷扬压力开关7的一端71；控制器9的接地端、显示器3的接地端同时接地，传感器8的信号端82连接控制器9的第一输入接口152端，作为示例而非限制，控制器9的152端可 以是模拟量输入端，传感器8的接地端83连接控制器9的模拟量地接口133端；加压卷扬压力开关7的另一端72连接控制器9的第二输入接口123端，作为示例而非限制，控制器9的123端可以是数字量输入端；加压选择开关6的另一端62连接控制器9的第三输入接口126端，作为示例而非限制，控制器9的126端可以是数字量输入端；显示器3的两CAN接口CAN-H和CAN-L之间连接有并联的第一电阻4和第二电阻5，为了提高总线信号传输的可靠性，作为示例而非限制，第一电阻4和第二电阻5可以选用120欧姆的电阻；显示器3的CAN-H接口和CAN-L接口同时连接到控制器9的CAN总线接口；控制器9的两个第一输出接口105端和106端分别连接加压提升电磁阀101和加压下放电磁阀102，控制器9的第二输出接口117端连接加压卷扬制动电磁阀11。
本发明还提出一种包括前述实施例中的卷扬加压控制装置的旋挖钻机。下面说明卷扬加压控制装置在旋挖钻机工作时的控制过程。
当旋挖钻机进行卷扬加压施工时，首先打开加压选择开关6，控制器9的126管脚检测到输入信号，控制105、106管脚输出控制信号，使加压提升电磁阀101、加压下放电磁阀102得电，此时操作先导手柄，打开先导油路，先导油打开主油路，同时使加压卷扬压力开关7闭合，此时控制器的123管脚检测到输入信号，控制117管脚输出控制信号，使加压卷扬制动电磁阀11得电闭合，以打开加压卷扬制动器，即可控制液压系统进行卷扬提升、下放操作。当停止先导手柄操作时，先导油压力消失，主油路关闭，同时加压卷扬压力开关7断开，此时控制器的123管脚检测不到输入信号，可以在延时预设的一段时间T后，控制117管脚停止输出控制信号，使加压卷扬制动电磁阀11失电，以关闭加压卷扬制动器，即可使液压系统停止卷扬提升、下放操作。延时关闭加压卷扬制动器可以减少制动对液压系统的冲击，延长液压件的使用寿命，并减少制动造成的钻机晃动。
在卷扬加压发生异常时，传感器检测到的主卷提升力会立刻增加，在传感器检测到的主卷提升力超过预设的提升力阈值的情况下，此时控制器9的152端检测到输入信号，并控制第一输出接口106端或105端 无输出，使加压下放电磁阀102或加压提升电磁阀101失电，断开先导油路，加压卷扬压力开关7同时断开，控制器9的123端检测不到输入信号，则控制第二输出接口117端无输出，使加压卷扬制动电磁阀11失电，以关闭加压卷扬制动器。此时先导手柄虽仍未停止加压操作，但加压动作已自动停止，无法继续加压。此时可以停机，排除故障后，再恢复正常操作。从而能够在卷扬加压发生异常时，使加压卷扬停止加压，可以避免钻机的结构损坏，提高卷扬加压机型施工的安全性和可靠性。本实施例中控制器的输出接口无输出以使加压提升电磁阀101、加压下放电磁阀102、加压卷扬制动电磁阀11失电，仅是电磁阀失电的一种示例性控制方式，还可以输出其他控制信号以使电磁阀失电。
在钻头往孔内下放或挖好土向上提升时，主卷提升力超过预设的提升力阈值，则会发生上述卷扬加压异常的情况。例如，钻头往孔内下放，当钻头尚未到达孔底，动力头加压键与钻杆提前锁止，而操作者并未发觉，仍进行加压操作时，则可能会发生卷扬加压异常。
提升力阈值的一种示例性设置方法为，将提升力阈值设置为主卷额定提升力FM的K倍，优选地，K的范围为90％～130％，例如可以选取110％、120％等数值，从而既可以保证施工安全，又可以防止误判而影响正常施工。
控制器9可以将传感器8输入的主卷提升力电信号转换为主卷提升力数值，并通过CAN总线传输至显示器3进行实时显示，使操作者可随时观察到数值的变化，若数值变化异常，可立即停止操作，更加直观、方便、安全。
本发明还提出一种卷扬加压控制装置的控制方法，包括：通过传感器8检测主卷提升力；在传感器8检测到的主卷提升力超过预设的提升力阈值的情况下，控制器9向加压控制电磁阀10发出控制信号使其失电，以断开先导油路，使加压卷扬压力开关7断开；在控制器9的第二输入接口检测不到加压卷扬压力开关7的输入信号的情况下，控制器9向加压卷扬制动电磁阀11发出控制信号使其失电，以关闭加压卷扬制动器。从而能够在卷扬加压发生异常时，使加压卷扬 停止加压，可以避免钻机的结构损坏，提高卷扬加压机型施工的安全性和可靠性。
进一步，在控制器9的第二输入接口检测不到加压卷扬压力开关7的输入信号的情况下，控制器9延时预设的一段时间后，向加压卷扬制动电磁阀11发出控制信号使其失电，以关闭加压卷扬制动器。延时关闭加压卷扬制动器可以减少制动对液压系统的冲击，延长液压件的使用寿命，并减少制动造成的钻机晃动。
进一步，控制器9还可以将主卷提升力传输至显示器3进行显示，使操作者可随时观察到数值的变化，若数值变化异常，可立即停止操作，更加直观、方便、安全。
进一步，在进行卷扬加压施工时，在控制器9的第三输入接口检测到加压选择开关6发出的进行卷扬加压的指示信号的情况下，控制器9向加压控制电磁阀10发出控制信号使其得电；在控制器9的第二输入接口检测到加压卷扬压力开关7的输入信号的情况下，控制器9向加压卷扬制动电磁阀11发出控制信号使其得电，以打开加压卷扬制动器，即可控制液压系统进行卷扬提升、下放操作。
