Novel steel structure engineering protection support convenient to assemble and disassemble

YE CHUNHUA

The invention provides a novel steel structure engineering protection support convenient to assemble and disassemble, and relates to the technical field of protection supports. The clamping sleeve is movably clamped in the mounting piece, and the hexagonal end of the bolt is clamped in the clamping sleeve; the rotating assembly comprises a ratchet wheel and a rotating shaft, the ratchet wheel is coaxially connected with the rotating shaft, a bevel gear is fixedly arranged outside the rotating shaft, and the rotating shaft is fixedly connected with a clamping sleeve. The screwing structure comprises a push plate, the push plate is fixedly connected with a ratchet wheel, when an elastic rod is pressed, a pawl is pushed to move to be meshed with the ratchet wheel, a pull rod is pulled to drive the pawl to rotate, the pawl pushes the ratchet wheel to rotate, the ratchet wheel drives a bevel gear to rotate through a rotating shaft, and the bevel gear drives the clamping sleeves to rotate through a transmission shaft, so that synchronous rotation of the three sets of clamping sleeves is achieved. And similarly, the bolt on the auxiliary connecting piece is fastened, and the mounting piece is placed reversely, so that the bolt can be disassembled, assembly or disassembly is convenient, and the problem that the protective support is inconvenient to assemble and disassemble is solved.

本发明提供了一种便于组装拆卸的新型钢结构工程防护支架，涉及防护支架技术领域，包括主连接件；所述安装件内部活动卡接卡套，卡套的内部卡接螺栓的六边形端头；所述转动组件包括棘轮和转轴，棘轮同轴连接转轴，转轴外部固定设置锥齿轮，且转轴固定连接卡套；所述旋拧结构包括有推板，推板固定连接棘轮，当按动弹性杆后推动棘爪移动使其能够与棘轮啮合，拉动拉杆带动棘爪转动，棘爪推动棘轮转动，棘轮通过转轴带动锥齿轮转动，锥齿轮通过传动轴带动卡套转动，从而实现三组卡套的同步转动，使得螺栓可以紧固，同理完成辅连接件上的螺栓紧固，反向放置安装件，则可以对螺栓进行拆卸，方便组装或拆卸，解决了不便于防护支架的组装拆卸的问题。
