Bracket for construction hoist

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 whe
