技术领域
本发明涉及通讯技术领域， 尤其涉及一种微波天线调节装置。 背景技术
微波传输是一种应用十分广泛的通信传输方式。 微波传输需要 提供一对微波天线进行信号传输， 因此要选择微波传输， 必须成对 安装微波天线， 微波天线一般安装在铁塔或楼顶抱杆， 涉及高空安 装、 天线对调等复杂操作。 天线对调分粗调和精调， 粗调目 的是找 信号， 找到信号后， 再进行精调， 精调目 的是把信号调到符合指标 值。 精调到位后， 需保持天线位置不变， 将天线固定， 此时对调任 务结束。
微波天线精调的现有技术一的方案是提供一种具有调节功能的 挂件， 微波天线安装在这种挂件上， 安装人员通过调节挂件上的水 平调节螺栓和俯仰调节螺栓， 来带动固定在挂件上的微波天线， 从 而使微波天线实现水平转动和俯仰转动。 但是， 在调节时通常是通 过手来拉动调节螺栓进行角度调节， 手动调节精度低， 而且固定时 存在窜动， 需要反复调节固定。
现有技术二的技术方案是设计安装有蜗轮蜗杆机构的挂件， 微 波天线固定安装在这种挂件上， 当进行水平方位角调节时旋转水平 调节手柄， 当进行俯仰角调节时旋转俯仰调节手柄。 然而， 虽然可 以通过涡轮蜗杆机构提高调节精度， 但每套挂件都需要一套涡轮蜗 杆机构， 增加了物料成本。 发明内容 本发明的实施例提供一种微波天线调节装置， 在满足水平调节 精度的前提下降低调节成本。
为达到上述目 的， 本发明的实施例采用如下技术方案：
一种微波天线调节装置， 包括固定安装在基础上的抱箍件和挂 载微波天线的挂载件， 所述抱箍件和所述挂载件通过第一铰接轴铰 接；
所述微波天线调节装置还包括调节机构， 所述调节机构包括第 一支架和第二支架， 所述第一支架和所述第二支架通过第二铰接轴 铰接， 所述第一支架与所述抱箍件可拆卸地连接， 所述第二支架与 所述挂载件可拆卸地连接； 所述第二支架上设有蜗杆， 所述第一支 架上固定连接有与所述蜗杆配合的涡轮； 所述第二支架上设有驱动 机构， 用来驱动所述蜗杆转动， 以使所述蜗杆驱动所述涡轮转动。
具体地， 所述驱动机构包括相互啮合的第一齿轮和第二齿轮， 所述第一齿轮与所述蜗杆同轴固定连接， 所述第二齿轮连接驱动其 转动的手摇把柄。
优选地， 所述第二支架上还设有用于与所述挂载件固定连接的 螺钉。
可选地， 所述第二支架与所述挂载件通过螺栓连接或卡接 其次， 所述抱箍件上设有定位孔， 所述第一支架上设有与所述 定位孔配合的定位销。
可选地， 所述抱箍件与所述第一支架通过螺栓连接或卡接。 再次， 所述微波天线调节装置还包括紧固螺母和与所述紧固螺 母配合的螺纹杆， 所述螺纹杆的一端与所述挂载件铰接， 另一端通 过所述紧固螺母与所述抱箍件连接。
进一步地， 所述抱箍件上设有过孔， 所述螺纹杆穿过所述过孔， 所述紧固螺母包括第一紧固螺母和第二紧固螺母， 所述第一紧固螺 母和第二紧固螺母分别位于所述过孔的两侧。
其中， 所述第二齿轮与所述手摇把柄为可拆卸地连接， 所述手 摇把柄还用于驱动所述挂载件上的俯仰调节螺母转动。 本发明实施例提供的微波天线调节装置， 当进行微波天线调节 时， 将所述调节机构的所述第二支架与所述挂载件连接， 将所述第 一支架与所述抱箍件连接。 由于所述蜗杆与所述涡轮配合连接， 而 且所述抱箍件通常是与基础固定连接， 因此所述第一支架相对于基 础是固定的， 这样最终所述第二支架相对于所述第一支架在水平面 内转动， 带动所述挂载件连接的所述微波天线在水平面内转动， 即 完成了微波天线的水平调节。 当微波天线的位置调节完成后， 可以 将所述调节机构取下， 而不是永久滞留在高空， 这样就延长了调节 机构的使用寿命， 减少了调节机构的数量， 降低了成本。 另外由于 涡轮蜗杆机构为一种高精度的线' f生调节机构， 进行微波天线水平调 节时， 调节过程为线性变化的过程， 微波信号变化连续且无跳动， 调节精度高。 附图说明

所述第二支架 40上设有蜗杆 41 , 所述第一支架 30上固定连接 有与所述蜗杆 41 配合的涡轮 3 1 ; 所述第二支架 40上还设有驱动机 构 42 , 用来驱动所述蜗杆 41转动， 以使所述蜗杆 41驱动所述涡轮 3 1转动。
本发明实施例提供的微波天线调节装置， 当进行微波天线调节 时， 将所述调节机构 1 1 1 的所述第二支架 40与所述挂载件 20连接， 将所述第一支架 30与所述抱箍件 10连接。 由于所述蜗杆 41与所述 涡轮 3 1 配合连接， 而且所述抱箍件 10通常是与基础 1 固定连接， 因此所述第一支架 30相对于基础 1是固定的， 这样最终所述第二支 架 40相对于所述第一支架 30在水平面内转动， 带动所述挂载件 20 连接的所述微波天线 2 在水平面内转动， 即完成了微波天线的水平 调节。 当微波天线 2 的位置调节完成后， 可以将所述调节机构 1 1 1 取下， 而不是永久滞留在高空， 这样就延长了调节机构 1 1 1 的使用 寿命， 减少了调节机构 1 1 1 的数量， 降低了成本。
另外由于涡轮蜗杆机构为一种高精度的线性调节机构， 进行微 波天线水平调节时， 调节过程为线性变化的过程， 微波信号变化连 续且无跳动， 调节精度高。 因此本发明实施例解决了现有调节装置 水平调节精度低、 成本高的问题。
对于上述实施例需要说明的是， 所述涡轮蜗杆机构优选采用带 有自锁功能的涡轮蜗杆机构， 即仅蜗杆驱动涡轮转动， 调节至所需 位置后， 无需其它辅助定位工具， 即可使调节位置处于稳定的状态， 调节稳定性更高。
具体地， 如图 4 所示， 所述驱动机构包括相互啮合的第一齿轮 44和第二齿轮 45 , 所述第一齿轮 44与所述蜗杆 41 同轴固定连接， 所述第二齿轮 45 连接驱动其转动的手摇把柄 46。 这样可通过转动 手摇把柄 46驱动所述第二齿轮 45转动， 进而驱动所述第一齿轮 44 转动， 最终通过蜗杆 41 驱动所述涡轮 3 1 转动。 通常作为主动轮的 第二齿轮 45采用小直径齿轮， 而作为从动轮的第一齿轮 44采用大 直径齿轮， 这样二者配合相当于减速机构， 可以实现均勾的线性传 动。 在本发明的其它实施例中也可以采用其它工具驱动第二齿轮 45 转动或是整个驱动机构采用电机驱动。
优选地， 如图 1所示， 所述第二支架 40上还设有用于与所述挂 载件 20 固定连接的螺钉 43。 所述第二支架 40与所述挂载件 20 的 固定连接可以采用普通的机械连接， 例如螺钉、 螺栓； 也可以是将 第二支架 40设计成一定的结构直接卡在挂载件上卡接， 或是本领域 技术人员可以想到的可以实现第二支架 40与挂载件 20可拆卸地连 接的其它机械连接方式。
优选地， 如图 1和图 5所示， 所述抱箍件 10上设有定位孔 1 1 , 所述第一支架 30上设有与所述定位孔 1 1 配合的定位销 33。 这样实 现了所述第一支架 30和所述抱箍件 10 的精确定位连接， 使二者不 发生相对运动； 而且采用定位销 33 和定位孔 1 1 配合连接， 操作方 便， 用时插上， 不用时拔下即可。 本发明并不局限于此， 所述第一 支架 30和所述抱箍件 10也可以采用其它的定位方式， 比如螺钉连 接或螺栓连接， 或是卡接； 或者所述第一支架 30也可以不与所述抱 箍件 10直接连接， 只是支撑在所述抱箍件 10上， 将所述第一支架 30设计成能抱住所述基础 （ 比如线杆） 的结构， 只要能实现所述第 一支架 30与所述基础不产生相对运动即可。
其次， 如图 6所示， 所述微波天线调节装置还包括紧固螺母 24 和与所述紧固螺母 24配合的螺纹杆 23 , 所述螺纹杆 23 的一端通过 第三铰接轴 22与所述挂载件 20铰接， 另一端通过所述紧固螺母 24 与所述抱箍件 10连接。 这样当进行微波天线的位置调节时， 松开所 述紧固螺母 24 , 使所述挂载件 20相对于所述抱箍件 10在水平面内 转动， 当调节完毕后， 将所述紧固螺母 24 拧紧实现所述挂载件 20 与所述抱箍件 10的相对固定连接进而实现所述微波天线 1 的固定。
优选地， 如图 6所示， 所述抱箍件 10上设有过孔， 所述螺纹杆 23 穿过所述过孔， 所述紧固螺母 24 包括第一紧固螺母 241 和第二 紧固螺母 242 , 所述第一紧固螺母 241 和第二紧固螺母 242 分别位 于所述过孔的两侧。 这样当需要顺时针调节微波天线 2 时， 即松开 第二紧固螺母 242 , 使所述挂载件 20可以顺时针转动， 当需要逆时 针旋转微波天线 2 时， 即松开第一紧固螺母 241 , 使所述挂载件 20 可以逆时针转动。 调节完毕后将对应松开的紧固螺母拧紧实现所述 微波天线的固定。
如图 6所示， 所述第二齿轮 45与所述手摇把柄 46为可拆卸地 连接， 所述手摇把柄 46还可用于驱动所述挂载件 20上的俯仰调节 螺母 21转动。 其中， 所述俯仰调节螺母 21可与所述手摇把柄 46配 合。 这样在进行所述微波天线 2 的俯仰角调节时就可以使用所述手 摇把柄 46调节， 而无需再配备专门的调节工具。 当然也可以用其它 工具或手动调节。
对于本实施例， 如图 6和图 7所示， 挂载件 20的下端设有 U型 钣金 26 , 俯仰调节螺母 21贯穿 U型钣金 26的端部过孔， 所述端部 过孔与俯仰调节螺母 21 之间具有一定的径向间隙， 挂载件 20上设 有与俯仰调节螺母 21 适配的调节螺纹孔 （未图示）， 旋转俯仰调节 螺母 21 时， 挂载件 20的下端相对于 U型钣金 26沿 U型槽滑动。
波天线 2的安装板 3 的上端和下端分别设有上部螺纹孔 25 1 和下 部螺纹孔 252 , 挂载件 20的上端设有与上部螺纹孔 25 1对应的螺纹 过孔， 并在所述螺纹过孔和所述上部螺纹孔中穿设有第一螺钉 （未 图示）； U型钣金 26的两侧板具有对应的穿孔 （未图示）， 穿孔位置 与安装板 3 的下部螺纹孔 252对应， 第二螺钉 （未图示） 插入对应 的侧板穿孔和下部螺纹孔 252。 则旋转俯仰调节螺母 21 时， 由于端 部过孔与俯仰调节螺母 21之间具有间隙， 则 U型钣金 26可以前后 移动并作小幅度的转动， 从而带动与之连接的安装板 3 绕所述第一 螺钉和所述第二螺钉转动， 从而实现微波天线 2的俯仰角的调节。
微波天线的俯仰调节时采用俯仰调节螺母， 是因为微波天线的 精调主要是水平位置的调节， 俯仰角调节相对较容易， 因此进行俯 仰角调节时没有采用涡轮蜗杆机构， 这样可以简化调节装置的结构， 降低成本。
下面结合图 1 -图 7对本发明实施例提供的微波天线调节装置的 调节过程进行描述。
101、将调节机构 1 1 1 的第一支架 30通过定位销 33与定位孔 1 1 的配合固定在抱箍件 10上；
102、 将调节机构 1 1 1上的第二支架 40上的螺钉 43拧紧， 使第 二支架 40与挂载件 20 固定连接；
103、 根据需要松开螺杆 23 上的第一紧固螺母 25 1 或第二紧固 螺母 252 ;
104、 通过转动手摇把柄 46使挂载件 20在第二支架 40的带动 下顺时针或逆时针转动， 进行水平定位；
105、 将第一紧固螺母 25 1或第二紧固螺母 252拧紧实现微波天 线 2的固定；
106、 将调节机构 1 1 1上的手摇把柄 46取下， 套在挂载件 20上 的俯仰调节螺母 21 上， 转动手摇把柄 46 实现微波天线 2 的俯仰调 节。
107、 完成微波天线调节后， 松开螺钉 43 , 将调节机构 111取下。 以上所述， 仅为本发明的具体实施方式， 但本发明的保护范围 并不局限于此， 任何熟悉本技术领域的技术人员在本发明揭露的技 术范围内， 可轻易想到变化或替换， 都应涵盖在本发明的保护范围 之内。 因此， 本发明的保护范围应以权利要求的保护范围为准。
