上述控制系统300通过设置用于控制卸砟门30的开关和犁片220的升降的液压系统310，所述液压系统310连接并用于控制所述液压系统310的电气控制系统320，以及用以为所述电气控制系统320提供动力，从而能够提供足够控制卸砟门30的开关和犁片220的升降的作用力，保证所述卸砟门30的开关和犁片220的升降，从而解决了现有技术中由于机车提供的压缩空气风压较低，难以满足重载车辆的卸砟门的开门力的需要的问题。
实施例二
基于同样的发明构思，本申请还提供一种具有该控制系统的工程车，所述工程车包括用于开关卸砟口的卸砟门、用于平砟的犁片和控制系统，所述控制系统用于控制所述卸砟门的开关和犁片的升降。所述控制系统与实施例一中的控制系统相同，在此不再详述。
上述工程车的控制系统通过设置用于控制卸砟门30的开关和犁片220的升
降的液压系统310，所述液压系统310连接并用于控制所述液压系统310的电气控制系统320，以及用以为所述电气控制系统320提供动力，从而能够提供足够控制卸砟门30的开关和犁片220的升降的作用力，保证所述卸砟门30的开关和犁片220的升降，从而解决了现有技术中由于机车提供的压缩空气风压较低，难以满足重载车辆的卸砟门的开门力的需要的问题。
尽管已描述了本发明的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
