MEI FAKE / ZHANG HAO / HE YAODIE / ZHU JIE / HAN JIANRONG

The invention relates to the technical field of drilling, in particular to a steel structure engineering construction anti-falling device which comprises a bottom frame, a throwing groove formed in the bottom frame, an intercepting pipe arranged in the throwing groove, a protection plate hinged to one end in the throwing groove and a prompt plate hinged to the other end in the throwing groove. The guardrail frames are connected to the four corners of the periphery of the bottom frame in a rotating mode, the control plates are supported on the intercepting pipes, a sinking cavity is formed in the bottom of the bottom frame, the two ends of the bottom of the bottom frame are each provided with a carrying plate in a welded mode, clamping cavities located at the two ends of the bottom of the bottom frame are formed between the two carrying plates and the sinking cavity, the number of the intercepting pipes is multiple, and the number of the intercepting pipes is multiple. When the protection plate is opened upwards, the two interception pipes in the middle can be linked to be far away from each other, so that the throwing space is enlarged, the situation that the positions of the interception pipes are changed when the interception pipes are manually and independently operated again is not needed, and operation is convenient.

本发明涉及钻探技术领域，尤其是提供了一种钢结构工程施工用防坠装置，包括底架，开设在所述底架内的投放槽、设置在所述投放槽内的拦截管、铰接在所述投放槽内一端的防护板、铰接在所述投放槽内另一端的提示板，转接在所述底架外围四个角上的护栏架，以及支撑在所述拦截管上的控制板，所述底架的底部设有沉腔，所述底架的底部两端各焊接有一片载板，两所述载板与所述沉腔之间构成了位于所述底架底部两端的装夹腔，所述拦截管为若干根，若干根所述拦截管拦截在所述投放槽内，防护板向上开启时，即可联动中间的两拦截管距离变远，使投放空间变大，无需人为手动再次单独操作拦截管发生位置变化，便于操作。
