Safety protection device for horizontal hole
The invention discloses a horizontal hole safety protection device which comprises at least two baffles used for covering a hole, the baffles are arranged around a central supporting column, one end of each baffle is rotationally connected with the central supporting column, the lower side face of each baffle is rotationally connected with one end of a tension bar, and the other end of each tension bar is connected with a horizontal hole. One end of the tension bar is rotatably connected with the central supporting column, the other end of the tension bar is rotatably connected with a sliding sleeve, the sliding sleeve is sleeved on the central supporting column in a sliding manner, a clamping part positioned above the sliding sleeve is fixed on the central supporting column, and the clamping part prevents the sliding sleeve from continuously moving upwards along the central supporting column. The baffles are fixed to the horizontal position so as to cover the hole, when the baffles need to be moved away, the center supporting column only needs to be pulled upwards, the baffles naturally droop, the two baffles 1 are relatively close to each other, and therefore storage and transportation are convenient.
本发明公开了一种水平洞口安全防护装置，包括用于覆盖在洞口上的挡板，所述挡板至少为两个，所述挡板围绕一中心支柱设置，所述挡板一端与所述中心支柱转动连接，所述挡板下侧面与一拉力杆一端转动连接，所述拉力杆另一端与一滑套转动连接，所述滑套滑动的套在所述中心支柱上，所述中心支柱上固定有位于所述滑套上方的卡止部，所述卡止部防止所述滑套沿所述中心支柱继续向上移动。本发明从使得所述挡板固定在水平位置，从而覆盖在所述洞口上，需要移走挡板时，只要向上拉起所述中心支柱即可，所挡板自然下垂，两个所述挡板1相对的靠近，从而便于收纳与运输。
