技术领域
本申请涉及高空作业领域，尤其是涉及一种高空作业平台以及具有该高空作业平台的臂车。
背景技术
在高空作业领域中，操作者一般是站立在高空作业平台上通过操作控制面板来调整高空作业平台的高度，等高空作业平台上升到一定的高度后停止操作。为了作业的方便以及同时观察到臂车车体底架周边的情况，操作人员一般是面朝车体，背朝障碍物。当障碍物接近操作人员时极有可能发生操作人员被夹在障碍物与操作控制面板之间，甚至可能发生生命危险。传统的高空作业平台通常采用在护栏上安装限高杆，此方式的缺点是限高杆可能被压坏。因此需要进一步地提升高空作业平台在防止操作人员被夹伤时的安全性能。
发明内容

实施例一：
如图1、图2所示，实施例一所涉及的高空作业平台，包括：工作栏100、支座200以及防夹组件300。
具体地，支座200安装在工作栏100上，工作栏100用于供操作人员站立；防夹组件300包括预定位件310、防夹杆320、信号传感器(未示出)以及防夹处理模块(未示出)，预定位件310安装在支座200上，防夹杆320可活动地连接在支座200上，预定位件310用于使防夹杆320具有朝向初始位置运动的势能，信号传感器与防夹处理模块电性连接。
其中，信号传感器在防夹杆320被操作沿预设方向运动而脱离初始位置的情况下被触发，而向防夹处理模块传递信号。
需要说明的是，初始位置为防夹杆320在图1、图2中所示的位置。
进一步地，预设方向为图1的x所指的方向，该方向为逆时针方向。
在上述的高空作业平台中，由于防夹组件300中的预定位件310用于使防夹组件300中的防夹杆320具有朝向初始位置运动的势能，因此当站在工作栏100上的操作人员正常操作高空作业平台进行升降，并且没有触碰到障碍物时，防夹杆320能够位于初始位置。当站在工作栏100上的操作人员后背触碰到障碍物而前倾时，身体会触碰到可活动地连接在支座200上的防夹杆320，从而操作人员会施加给防夹杆320一个压力，导致防夹杆320会沿着预设方向运动而脱离初始位置。此时，由于信号传感器与防夹处理模块电性连接，因此当信号传感器检测到防夹杆320脱离初始位置的信号时会被触发，立即将信号传递给防夹处理模块，以使防夹处理模块进行处理，进一步防止操作人员被夹伤。
其中，防夹处理模块为控制器，其处理芯片可以但不限于单片机、ARM(Advanced RISC Machine，高端精简指令集机器)和FPGA(Field－Programmable Gate Array，现场可编程门阵列)。防夹处理模块与高空作业平台的电源系统(未示出)和/或警报器400电性连接。当防夹处理模块接收到来自于信号传感器的信号后，防夹处理模块切断高空作业平台的电源和/或使警报器400发出警报，使得操作人员停止对高空作业平台的升降，防止操作人员被夹伤。如图1、图2所示，在实施例一中，支座200安装在工作栏100的顶部，防夹杆320位于工作栏100靠近臂架的一侧。
具体地，臂架位于臂车的车体与高空作业平台之间。
由于操作人员在操作上述的高空作业平台进行升降时，为了作业的方便一般是面朝臂车的车体，背朝障碍物，因此防夹杆320设置于工作栏100靠近臂架的一侧有利于将防夹杆320设置于朝向操作人员的一侧。当操作人员后背触碰到障碍物而前倾时，身体会触碰到朝向操作人员的防夹杆320，从而触发防夹操作，避免操作人员被夹伤。
如图1、图2所示，在实施例一中，预定位件310为磁性件，磁性件与防夹杆320磁吸配合。
具体地，防夹杆320能够被磁性件吸附在初始位置。
进一步地，信号传感器位于磁性件处。
当防夹杆320被操作沿预设方向运动而脱离初始位置时，磁性件与防夹杆320之间的磁吸配合失效。此时，当位于磁性件处的信号传感器检测到防夹杆脱离初始位置的信号时会被触发，立即将信号传递给防夹处理模块，当防夹处理模块接收到来自于信号传感器的信号后，防夹处理模块切断高空作业平台的电源或者使警报器400发出警报，使得操作人员停止对高空作业平台的升降，从而避免操作人员被夹伤。
当操作人员的危险解除时，此时可操作防夹杆320沿预设方向的反方向运动，由于磁性件与防夹杆320磁吸配合，则防夹杆320能够再次被磁性件吸附在初始位置，从而能够解除防夹操作。
如图1、图2所示，在实施例一中，防夹组件300还包括第一连接件330，第一连接件330可转动地连接在支座200上，并被配置成应用杠杆原理的构件，第一连接件330的一端与防夹杆320连接，第一连接件330的另一端与预定位件310磁吸配合。
具体地，第一连接件330的转动中心位于防夹杆320的中心轴线的上方。由于第一连接件330被配置成应用杠杆原理的构件，且第一连接件330的转动中心位于防夹杆320的中心轴线的上方，因此当防夹杆320受到操作人员所施加的压力时，防夹杆320能够绕其转动中心沿预设方向运动，从而使得第一连接件330与防夹杆320连接的一端沿预设方向运动，进一步地使得第一连接件330与预定位件310连接的一端沿预设方向运动，则 第一连接件330与预定位件310的磁吸配合失效。此时，位于磁性件处的信号传感器检测到防夹杆脱离初始位置的信号被触发，从而触发防夹操作，避免操作人员被夹伤。
当防夹杆320不再受到操作人员所施加的压力时，能够操作防夹杆320绕其转动中心沿预设方向的反方向运动，从而使得第一连接件330与防夹杆320连接的一端沿预设方向的反方向运动，进一步地使得第一连接件330与预定位件310连接的一端沿预设方向的反方向运动，则第一连接件330恢复预定位件310的磁吸配合，从而解除防夹操作。
如图1、图2所示，在实施例一中，防夹组件300还包括限位件340，限位件340固定连接在支座200上，且限位件340位于预设方向的前方。
如此，当防夹杆320被操作沿预设方向运动时，位于预设方向的前方的限位件340能够起到对防夹杆320的限位作用，从而能够给操作人员在前倾时提供支撑力，防止操作人员由于前倾而摔伤。
实施例二：
如图3、图4所示，在实施例二中，预定位件310为弹性件，弹性件的一端与支座200连接，弹性件的另一端与防夹杆320连接，弹性件用于向防夹杆320提供沿预设方向的反方向运动的势能。
需要说明的是，初始位置为防夹杆320在图3、图4中所示的位置。
进一步地，预设方向为图3的y所指的方向，该方向为逆时针方向。
具体地，弹性件为弹簧。
进一步地，信号传感器位于弹性件处。
当防夹杆320被操作沿预设方向运动而脱离初始位置时，位于弹性件处的信号传感器检测到防夹杆脱离初始位置的信号时会被触发，从而触发防夹操作，避免操作人员被夹伤，此时，弹簧由于被拉长而具有了弹性势能，从而使得与弹簧连接的防夹杆320具有沿预设方向的反方向运动的趋势。
当操作人员的危险解除时，则防夹杆320不再被操作沿预设方向运动，由于此时弹簧具有了弹性势能，则弹簧能够带动防夹杆320沿预设方向的反方向运动，从而防夹杆320能够自动回到初始位置，解除防夹操作。
弹簧的设置使得防夹杆320在回到初始位置时无需进行手动操作，则在进行防夹操作时能够更加地便捷。
如图3、图4所示，在实施例二中，防夹组件300还包括第二连接件350，第二连接件350可转动地连接在支座200上，并被配置成应用杠杆原理的构件，第二连接件350的一端与防夹杆320连接，第二连接件350的另一端与弹性件的另一端连接。
具体地，第二连接件350的转动中心位于防夹杆320的中心轴线的上方。
由于第二连接件350被配置成应用杠杆原理的构件，且第二连接件350的转动中心位于防夹杆320的中心轴线的上方，因此当防夹杆320受到操作人员所施加的压力时，防夹杆320能够绕其转动中心沿预设方向运动，从而使得第二连接件350与防夹杆320连接的一端沿预设方向运动，进一步地使得第二连接件350与弹性件连接的一端沿预设方向运动。此时，位于弹性件处的信号传感器检测到防夹杆脱离初始位置的信号被触发，从而触发防夹操作，避免操作人员被夹伤。同时，弹性件由于随着第二连接件350沿预设方向运动而被拉长，从而具有弹性势能，进一步地使得第二连接件350具有沿预设方向的反方向运动的趋势。
当防夹杆320不再受到操作人员所施加的压力时，由于弹性件所施加给第二连接件350的弹性势能，使得第二连接件350与弹性件连接的一端能够沿预设方向的反方向运动，从而第二连接件350与防夹杆320连接的一端能够沿预设方向的反方向运动，则第二连接件350自动回到初始位置，从而解除防夹操作。
实施例三：
如图5、图6所示，在实施例三中，防夹组件300还包括第三连接件360，第三连接件360可转动地连接在支座200上，并被配置成应用杠杆原理的构件，第三连接件360的一端与防夹杆320转动连接，第三连接件360的另一端与弹性件的另一端连接；
防夹组件300还包括第四连接件370，第四连接件370的一端与防夹杆320转动连接，第四连接件370的另一端与支座200转动连接。
其中，第三连接件360与防夹杆320转动连接的一端、第四连接件370与防夹杆320转动连接的一端、第三连接件360的转动中心以及第四连接件370的转动中心的连线配合构成平行四边形结构。
需要说明的是，初始位置为防夹杆320在图5、图6中所示的位置。
进一步地，预设方向为图5的z所指的方向，该方向为逆时针方向。
具体地，信号传感器位于弹性件处。
由于第三连接件360被配置成应用杠杆原理的构件，且第三连接件360的转动中心位于防夹杆320的中心轴线的上方，因此当防夹杆320受到操作人员所施加的压力时，防夹杆320能够绕其转动中心沿预设方向运动，从而使得第四连接件370与防夹杆320转动连接的一端能够沿预设方向运动。又由于第三连接件360与防夹杆320转动连接的一端、第四连接件370与防夹杆320转动连接的一端、第三连接件360的转动中心以及第四连接件370的转动中心的连线配合构成平行四边形结构，则第三连接件360与防夹杆320转动连接的一端能够沿预设方向运动。进一步地使得第三连接件360与弹性件连接的一端沿预设方向运动。此时，位于弹性件处的信号传感器检测到防夹杆脱离初始位置的信号被触发，从而触发防夹操作，避免操作人员被夹伤。同时，弹性件由于随着第三连接件360沿预设方向运动而被拉长，从而具有了弹性势能，使得第三连接件360具有沿预设方向的反方向运动的趋势。
当防夹杆320不再受到操作人员所施加的压力时，由于弹性件所施加给第三连接件360的弹性势能，使得第三连接件360与弹性件连接的一端能够沿预设方向的反方向运动，从而第三连接件360与防夹杆320连接的一端能够沿预设方向的反方向运动，第四连接件370与防夹杆320连接的一端能够沿预设方向的反方向运动，则第三连接件360自动回到初始位置，从而解除防夹操作。
一实施例所涉及的臂车，包括：上述的高空作业平台以及臂架。
具体地，臂架的一端与高空作业平台连接，臂架的另一端用于与臂车的底架连接。
在上述的高空作业平台中，由于防夹组件300中的预定位件310用于 使防夹组件300中的防夹杆320具有朝向初始位置运动的势能，因此当站在工作栏100上的操作人员正常操作高空作业平台进行升降，并且没有触碰到障碍物时，防夹杆320能够位于初始位置。当站在工作栏100上的操作人员后背触碰到障碍物而前倾时，身体会触碰到可活动地连接在支座200上的防夹杆320，从而操作人员会施加给防夹杆320一个压力，导致防夹杆320会沿着预设方向运动而脱离初始位置。此时，由于信号传感器与防夹处理模块电性连接，因此当信号传感器检测到防夹杆320脱离初始位置的信号时会被触发，立即将信号传递给防夹处理模块，以便防夹处理模块进行处理，进一步防止操作人员被夹伤。
在上述的臂车中，由于上述的高空作业平台能够提高臂车在防止操作人员被夹伤时的安全性能，因此上述的臂车具有更加安全的优点。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
