Safety protection device applied to water conservancy construction
The invention discloses a safety protection device applied to water conservancy construction. The safety protection device comprises a plurality of placement plates. Through holes are formed in the placement plates, expansion bolts are inserted into the through holes in a penetrating manner, and expansion pipe parts of the expansion bolts are arranged underground. A movable groove is formed in oneside of the placement plates, a rack is rotationally arranged in the movable groove, and a first support frame is arranged on the rack. A gear is rotationally arranged in the first support frame andengaged with the rack. By controlling a forward and reverse rotation button of a forward and reverse rotation controller, a gear motor rotates forward and reversely, a workbench is driven to move upwards or downwards along the rack, a connecting shaft is rotationally borne through a bearing, the connecting shaft rotates stably, the gear motor is provided with a band-type brake system, and when thegear motor stops rotating, a rotor shaft of the gear motor is self-locked; and the rotor shaft of the gear motor stops rotating immediately, so that the inner walls of the reservoirs with different heights can be maintained conveniently, and the inner walls of the reservoirs can be maintained more safely by using the safety protection device.
本发明公开了一种应用于水利施工的安全防护装置，包括多块安置板，安置板上设有穿孔，穿孔内穿插有膨胀螺栓且膨胀螺栓的膨胀管部装设在地下，安置板的一侧设有活动槽，活动槽内转动装设有齿条，齿条上装设有第一支撑框，第一支撑框内转动装设有齿轮且齿轮啮合齿条。通过控制正反转控制器的正反转按钮，使得减速电机正转和反转，带动工作台沿着齿条向上或者向下移动，通过轴承转动承接连接轴，使得连接轴转动稳定，减速电机自身带有抱闸系统，当减速电机停转时，减速电机转子轴自锁，减速电机的转子轴立即停止旋转，因此方便对不同高度的水库内壁实施维修，通过使用该安全防护装置，对水库内壁维修时更加安全。
