Description

可精确调节标尺角度的测量脚架
技术领域：
本发明涉及一种测量辅助装置，尤其是一种操作容易、 可精确调节标尺角度的测量脚架。
背景技术：
在大地测量及工程测量时，需要将测量标尺（水准测量标尺、全站仪反射棱镜对中杆、卫星定位测量对中杆等）直立在测量标志点上保持垂直且面对水准仪等测量装置，才可进行测量，即测量标尺的垂直状态及面对水准仪的偏转角度直接影响到测量精度。以往的测量脚架（三脚架）的外基座是平板状，无法应用于测量标尺，故需要测量人员手扶操作，即测量人员通过观察水准器的气泡是否居中来调整测量标尺，并通过手扶使测量标尺处于垂直状态，不仅费时费力，而且也难以保证精确整平，从而降低了测量的精确度。为了解决上述问题，专利号为 201220373858.9 的中国实用新型专利，公开了一种'套夹式测量脚架'，其主要贡献是将传统脚架的外基座由平板状（云台式结构）更改为环状（套夹式结构），首次为测量标尺提供了专用的测量脚架，提高了测量标尺直立垂直的精确度。专利号为 201310022381.9 的中国发明专利，公开了一种'抱夹式测量脚架'，进一步采用正交分解调整原理对'套夹式测量脚架'做了改进，加快了标尺直立状态的调整速度。具体操作过程是先将测量标尺置于基座内，通过固定连接装置使测量标尺与基座固定连接，将测量标尺底部放在测量标志点上，大致面向水准仪，再调整支脚的外张角和长度，架设测量标尺能够稳定并大致垂直，然后通过微调顶丝可精确使测量标尺处于垂直状态。然而，无论套夹式测量脚架或抱夹式测量脚架在实际应用中还存在以下不足：当测量标尺经调整至直立垂直状态后，经常会出现测量标尺并非精确面向（瞄准）水准仪的现象，需要重新进行标尺架设、调整垂直等过程，操作麻烦，否则将因测量标尺非精确面向（瞄准）水准仪而无法进行测量。
