Sinking horizontal protection and construction platform for hoistway

ZHANG LIANYU

The invention discloses a sinking horizontal type protection and construction platform for a hoistway. The sinking horizontal type protection and construction platform comprises a doorway fixing assembly and a construction assembly, and the supporting assembly is arranged at one end of the doorway fixing assembly and used for being attached to the inner wall of the hoistway so as to maintain the stability of the whole device, and the supporting assembly comprises a triangular supporting assembly used for adopting a triangular supporting technology and an auxiliary supporting assembly used for adopting an extrusion friction technology. A twisting block is driven to rotate and drives a worm gear rod to rotate, so that the worm gear rod drives a worm gear to rotate, the worm gear drives a third threaded rod to rotate, and a first threaded sleeve and a hinge arm are matched to drive an auxiliary supporting seat to approach the inner wall of a shaft until the auxiliary supporting seat is tightly attached to the inner wall of the shaft; and therefore, the purpose of stably supporting the device is further achieved by assisting the horizontal supporting main beam to be matched with the inclined strut, and the purpose that the device has high stability is achieved.

本发明公开了井道用下沉平放式防护兼施工平台，包括：用于与井道稳定安装的门口固定组件；支撑组件，设置在门口固定组件的一端且用于与井道的内壁进行贴合从而维持整个装置的稳定，所述支撑组件包括用于采用三角支撑技术的三角支撑组件和用于采用挤压摩擦技术的辅助支撑组件。本发明通过带动扭块转动，并使得扭块带动蜗轮杆转动，从而使得蜗轮杆带动蜗轮转动，使得蜗轮带动第三螺纹杆转动，配合第一螺纹套管和铰接臂带动辅助支撑座向井道的内壁靠近，直至辅助支撑座与井道的内壁紧密贴合，从而辅助水平支撑总梁配合斜撑支柱进一步起到稳定支撑该装置的目的，从而使得该装置具有较高稳定性的目的。
