Heavy lifting bracket clamped and fixed to doors and windows

Abstract

The invention discloses a heavy lifting bracket clamped and fixed to doors and windows. The heavy lifting bracket comprises a first clamping block. The heavy lifting bracket can be clamped in door andwindow parts, so when the heavy lifting bracket works, installation is convenient, the applicability is high, the heavy lifting bracket can be directly installed on parts to be lifted, the safety performance is relatively high, and the heavy lifting bracket can be directly matched with winch wheel equipment in the prior art, so as to facilitate the lifting effect of heavy equipment, thus the equipment can be directly lifted to a required floor, the work safety performance is good, and the convenience is high; moreover, the device is provided with a screw structure type movable contact plate clamping and fixing mechanism, and the device can be stably fixed to the wall faces of the door and window parts by using the movement limitation of a screw structure, so as to realize the fixing effect of a foundation part and improve the stability under a working state; and in addition, the device is provided with a reverse screw structure type distance effective adjusting mechanism, the installation function of doors and windows with different distances is achieved by using the reverse screw adjustment function, and the use range is improved.

Description

technical field [0001] The invention relates to the technical field of lifting brackets, in particular to a door and window clamping fixed heavy object lifting bracket.
