磁力电钻安全防护装置

Safety protection device for magnetic electric drill

Abstract

本实用新型涉及核电站建造领域,尤其涉及一种在核电站核岛安装施工中常用的磁力电钻的安全防护装置。为解决现有技术中使用磁力电钻安全性能低的问题。本实用新型提出一种磁力电钻安全防护装置,该装置包括U型紧固结构,卡件结构和锁紧结构;U型紧固结构的两个侧边连杆上设置有外螺纹;在卡件结构的两端设置有两个用来安装两个侧边连杆的连接通孔;锁紧结构包括设置有内螺纹的套环,套环上的内螺纹与侧边连杆上的外螺纹相匹配;在使用时,U型结构的侧边连杆的自由端从连接通孔中穿过形成一个矩形框架结构,套环从矩形框架结构的外部套设到侧边连杆的自由端上而锁紧该矩形框架结构。采用这种磁力电钻安全防护装置,提高了施工安全性。
The utility model relates to the field of nuclear power station construction, in particular to a safety protection device for a magnetic electric drill which is often used in installation and construction of a power station and a nuclear island, and aims at solving the problem that safety performance of a magnetic electric drill used in the prior art is low. The safety protection device for the magnetic electric drill comprises a U-shaped fastening structure, a clamping piece structure and a locking structure. Two side edge connecting rods of the U-shaped fastening structure are provided with outer threads. Two ends of the clamping piece structure are provided with two connecting through holes used for installation of the two side edge connecting rods. The locking mechanism comprises sleeve rings provided with inner threads matched with the outer threads on the side edge connecting rods. When the safety protection device for the magnetic electric drill is used, free ends of the side edge connecting rods of the U-shaped structure pass through the connecting through holes to form a rectangular framework structure, and the sleeve rings are sleeved on the free ends of the side edge connecting rods through the outside of the rectangular framework structure to lock the rectangular framework structure. By adoption of the safety protection device for the magnetic electric drill, construction safety is improved.
