The invention relates to the field of elevator brackets, and discloses a bracket for a construction elevator, which comprises a vertical frame, a lifting cage, a fixed seat, an elevator and a lifting mechanism, and connecting blocks are integrally formed at the two ends of the lifting cage; the two sides of the vertical frame and the sliding rod at the end of the fixing base form a right triangle structure through the four sets of telescopic swing rods, and the vertical frame and the fixing base are embedded into the ground of a building hoistway through the four sets of threaded piles, so that the vertical frame and the fixing base can be stably installed after the positions are adjusted; when the displacement sensor detects that the displacement of the cage on the inner side face of the vertical frame in unit time is too large, the controller can control the electric winding roller to conduct reverse winding, so that the situation that a lifting rope on the cage breaks and directly falls is avoided, and when the displacement sensor detects that the descending displacement of the cage on the vertical line is too large, the controller can control the two sets of electric air cylinders to conduct reverse winding. The telescopic end of the electric air cylinder can drive the clamping jaw to gradually get close to the jaw groove, after the clamping jaw is meshed with the jaw groove, the lifting cage can be braked emergently, and therefore a lifting rope above the lifting cage is prevented from breaking and falling.

    本发明涉及升降机托架领域,公开了一种施工升降机用托架,包括立架、吊笼、固定座、升降机、升降机构,所述吊笼两端一体成型有连接块;本发明立架两侧通过四组伸缩摆杆与固定座端部滑杆构成直角三角形结构,并通过四组螺纹桩嵌入建筑井道地面上,使得立架与固定座调整位置后可稳定安装;通过位移传感器检测吊笼在立架内侧面单位时间位移过大时,可通过控制器控制电动卷辊进行反向收卷,从而避免吊笼上吊绳断裂直接坠落,而位移传感器检测垂直线上吊笼下降位移过大时,可通过控制器控制两组电动气缸,电动气缸伸缩端可带动夹爪逐渐与爪槽靠近,夹爪与爪槽啮合后,可使得吊笼紧急制动,从而防止吊笼上方吊绳断裂坠落。
