Safety protection device for trench excavation
The invention discloses a safety protection device for trench excavation. The safety protection device comprises a supporting plate body, a fixing shell, a push rod, a linkage rod and a transmission mechanism. The pair of supporting plate bodies are oppositely arranged, and the multiple fixing shells are arranged between the pair of supporting plate bodies in the vertical direction at intervals. Each fixing shell is movably connected with the pair of supporting plate bodies through transmission mechanisms and push rods, the transmission mechanisms are in linkage connection through linkage rods, and the pair of push rods form an inverted-V-shaped structure or a linear structure between the fixing shells and the pair of supporting plate bodies, so that the pair of supporting plate bodies can abut against the groove walls of the two sides of the groove. The invention relates to the technical field of building construction and can solve the problems that in the prior art, a groove supporting structure is high in cost, large in occupied storage space and low in disassembly, assembly and replacement efficiency.
本发明公开了一种沟槽开挖的安全防护装置，包括支撑板主体、固定壳、推杆、联动杆和传动机构；一对支撑板主体相对设置，若干个固定壳沿竖向间隔设置在一对支撑板主体之间；每个固定壳分别通过传动机构经推杆与一对支撑板主体活动连接，若干组传动机构通过联动杆联动连接，一对推杆在固定壳与一对支撑板主体之间形成倒V形结构或一字形结构，使一对支撑板主体能顶撑在沟槽的两侧槽壁上。本发明涉及建筑施工技术领域，能够解决现有技术中沟槽支护结构成本高、占用存储空间大、拆装更换低效的问题。
