Description

一种可调支架及通信设备可调固定装置

技术领域
本申请涉及通信设备领域，例如涉及一种可调支架及通信设备可调固定装置。
背景技术
随着无线通信系统设备技术的发展，通信设备基站配置要求越来越高，对无线设备的安装方向要求也越来越高。大多通信设备(比如天线等)的俯仰角多是通过调节可调支架进行调节的。当通信设备需要调整俯仰角时，需要操作人员用扳手松动可调支架以及通信设备与抱杆的连接，然后用手推动通信设备的一端向远离或靠近抱杆及挂墙的方向移动，通信设备移动到位后需要操作人员将设备稳住，然后用扳手将可调支架以及通信设备与抱杆的连接进行紧固。因通信设备都比较重，依靠人工将通信设备推到位再固定非常不好操作，可靠性差效率低精度低，因抱杆设备大多都在高空，在这样高空作业有一定的危险性，这也给操作人员带来了很多不便。
