The invention discloses a safety protection device of the elevator for building construction. The safety protection device of the elevator for building construction comprises a supporting frame with a damping device arranged at the bottom, wherein an elevator car is arranged in the supporting frame, and guide wheels are arranged on the two sides of the elevator car. Each guide wheel comprises a rotating shaft, two fixing shafts, two wheel bodies and two sliding frames, wherein the fixing shafts are arranged at the ends of the rotating shaft in a sleeving mode, the fixing shafts are connected with the elevator car, electromagnetic coils are arranged on the fixing shafts, the wheel bodies are arranged on the rotating shaft in a sleeving mode, a plurality of floating abutting rods are arranged on each wheel body, driven wedge blocks connected to the inner ends of the floating abutting rods penetrate out of the inner side face of each wheel body, each sliding frame comprises a mandrel and a plurality of connecting rods distributed on the mandrel, each mandrel is located in a core hole of the rotating shaft, a magnet capable of repelling the corresponding electromagnetic coil is arranged on each mandrel, the connecting rods penetrate through the rotating shaft in the radial direction to extend outwards, the connecting rods are connected with driving wedge blocks, the driving wedge blocks are connected with the corresponding driven wedge blocks in a matched mode, and a pushing spring arranged on the rotating shaft in a sleeving mode abuts against the two sliding frames and located between the two sliding frames. The safety protection device of the elevator for building construction has a good protection effect, and the weight of the elevator car is not increased.
本发明公开了一种建筑施工用电梯的安全防护装置,包括底部设有减震装置的支撑架,支撑架内设有电梯厢,电梯厢的两侧设有导轮,导轮包括转轴、两个固定轴、两个轮体和两个滑架,固定轴套设在转轴的端部上,固定轴与电梯厢连接,固定轴上设有电磁线圈;轮体套设在转轴,轮体上设有多个浮动顶杆,连接在浮动顶杆内端的从动楔块穿出轮体的内侧面;滑架包括芯轴和分布在芯轴上的多个连接杆,芯轴位于转轴的芯孔内,且芯轴上设有能够与电磁线圈相斥的磁铁,连接杆沿径向穿过转轴向外延伸,连接杆连接有主动楔块,主动楔块与对应的从动楔块配合连接,套设在转轴上的顶压弹簧抵持在两个滑架之间。本发明防护效果好,且不增大电梯厢的重量。
