Telescopic orifice protection cover plate and use method thereof
The invention relates to the technical field of well lid opening and closing, aims to solve the problems that in the prior art, the structure is simple, the matching precision is low, the weight is large, tools are prone to falling off, personnel have the falling risk, the labor intensity is large, and the working efficiency is low, and provides a telescopic orifice protection cover plate and a using method thereof.The telescopic orifice protection cover plate comprises a driving device, a telescopic cover plate body, a fixing device and a locking device; the driving device is provided with an annular base, the top of the annular base is detachably connected with an annular guide rail, the annular guide rail is matched with an annular rack capable of rotating and sliding, a plurality of gears are arranged in the axial direction of the annular rack and connected to the annular rack in a meshed mode, and a guide sliding groove is formed in the top of the annular rack. The guide sliding groove is fixedly connected with the annular guide rail through a bolt, and the telescopic cover plate is connected to the guide sliding groove in a matched mode. The invention has the beneficial effects of reasonable structure, high matching precision, light weight, low safety risk, low labor intensity of operating personnel and high working efficiency, tools are not easy to fall off, and personnel cannot fall off in the opening process.
本发明涉及井盖启闭技术领域，旨在解决现有技术中结构简单、配合精度低、重量大、工具易掉落、人员有坠落风险、劳动强度大和工作效率低的问题，提供一种伸缩式孔口防护盖板及其使用方法，包括驱动装置、伸缩盖板、固定装置和锁定装置，驱动装置有环形底座，环形底座顶部可拆卸的连接有环形导轨，环形导轨上适配有可旋转滑动的环形齿条，环形齿条的轴向上设有若干齿轮，若干齿轮均齿合连接于环形齿条，环形齿条的顶部设有导向滑槽，导向滑槽通过螺栓与环形导轨固定连接，伸缩盖板可适配的连接在导向滑槽上。本发明有益效果是结构合理、配合精度高、重量小、工具不易掉落、开启过程中人员不会坠落、安全风险低、作业人员劳动强度小和工作效率高。
