Description

灵敏遥控缸
本发明涉及一种灵敏遥控缸。
起重机和空中作业平台使用了许多监测距离的装置，以确定构成起重机或空中作业平台的组成部分的某一部件如吊杆的长度和/或位置。这些测距装置需要依靠装置本身与部件的某处相接触来测定它的位置和/或长度。测距装置需要与部件相接触，限制了它的使用寿命，这是由于相互的物体接触磨损测距装置，并使其损坏。接触测量的测距装置还会由于不允许接触测量的外部原因而失效，这时就不能使用接触法测量。例如，大多数接触测量的测距装置采用电动开关，而结冰和冻雨就能使得电动开关失效。
另外，大多数的接触测距装置只能提供不连续的测量值。例如，当接触发生时，这个接触表明吊杆是在某一预定的位置或有着预定的长度。这样的接触测距装置不能提供连续的实时间变化的测量数据。接触测距装置的响应时间还很慢。当检测到接触还在继续时时，吊杆已不再位于预定的位置。因此，接触测距装置有着很多的缺点。
本发明的灵敏遥控缸，包括缸筒和活塞，非接触测距装置的发射器和接收器装在缸筒内。接收器接收由发射器发射并由活塞头部反射回来的电磁能量。非接触测距装置测出发射电磁能和接收电磁能之间的时间间隔。通过这一时间间隔可以得出活塞头和非接触测距装置的接收器之间的距离，这一距离与活塞的位置有关，因此也与灵敏遥控缸的长度有关。根据非接触测距装置的测量结果，控制器即可确定所需要知道的与灵敏遥控缸相连部件的距离。
例如，当本发明的灵敏遥控缸为一个吊杆或吊杆部分的延伸机构时，控制器可通过参考表格或方程式来确定与之相连的吊杆或吊杆部分的长度。
同样，非接触测量装置也可以输出发射电磁能和接收到电磁能之间的时间间隔，以代替输出距离测量值，控制器可由此确定出所需要知道的距离。
由于测量距离时不需要物体接触，因此本发明的灵敏遥控缸不会遇到前面提到的传统的接触测距装置的各种缺点和问题。
本发明的其他目的、特点和特征，机构的各相关部件的操作、方法和作用，各个部件的结合方式，制造的经济性等都将通过下面的实施例和附图清楚详细地说明。所有这些组成说明书的一部分，其中的标号在各图的相应部件上标出。
通过下面伴随附图的详细说明，可以更好地理解本发明；由于本发明的附图仅仅为示意图，因此不能作为对本发明的限制，其中：
图1为本发明的灵敏遥控缸实施例的示意图。
图1阐明了本发明的灵敏遥控缸100的一个实施例。如图所示，这一实施例中的灵敏遥控缸为液压灵敏遥控缸，它包括缸筒110，缸筒内有活塞120。MIR***105中的发射和接收天线130装在缸筒110内部的一端。最好将天线130装在螺钉135上，而螺钉135则拧入缸筒110的端部。
由于缸筒110的内壁和活塞120作为波导管，发射天线130发出的脉冲(电磁能)沿着缸筒110的纵向传播。脉冲由活塞120的活塞头125反射回来，反射脉冲被接收天线130接收。MIR***105中的MIR电子设备140接收到反射脉冲后，即可确定从天线130到活塞头125的距离。
MIR电子设备140将距离测量值输送至控制***150中。控制***150包括一个与ROM154和RAM156相连的处理器152。控制***150还包括一个参考表格，储存在ROM154或RAM156中，参考表格将所测的距离值换算成为所需要知道的与灵敏遥控缸100相连的部件的距离值。例如，当灵敏遥控缸100作为用以拉伸吊杆部分的伸缩缸筒时，参考表格将MIR电子设备140输出的距离测量值换算为吊杆部分的延伸长度(也就是所需要知道的距离)。由于参考表格的具体内容由所需要知道的距离值来确定，并且这些内容都已经由本领域的技术人员所熟知，因此这里就不对参考表格作过多的描述。
MIR电子设备140也能用输出发射脉冲和接收脉冲之间的具体时间间隔来代替输出距离测量值。在这种变形的实施例中，控制***150储存的参考表格能够将这一时间间隔换算成为所需要知道的距离值。
在另一替换例中，不用参考表格，而在控制***150中储存有方程式，将由MIR电子设备140输出的距离测量值或时间间隔换算成为所需要知道的距离值。
又一实施例是MIR电子设备140中储存有参考表格或方程式，能将时间间隔或距离测量值换算成为所需要知道的距离值
也可用其他不需要相互接触即可测量到某一物体距离的设备代替MIR***105，例如用声波、超声波、红外线、激光等测距仪器。
虽然本发明只描述了这几种方案，但是很显然本发明可以有多种实施方式。这些变化并没有被认为脱离了本发明的实质和范围，而且这些变化对本领域的技术人员来说是显而易见的，它们都应属于本发明申请的范围。
