Building material transport device

Abstract

A building material transport device comprises a base board fixedly installed on the ground, and a top board fixedly installed on a roof; two guide rods in bilateral symmetry and a lifting threaded rod located between the two guide rods are fixedly installed between the base board and the top board; a lifting frame is installed on the lifting threaded rod; guide holes are formed in the left and right sides of the lifting frame symmetrically; the guide holes and the guide rods are matched; guide sleeves are installed on the guide rods in a sliding mode; the upper end faces of the guide sleeves and the lower end face of the lifting frame are fixedly connected; a triangular board is fixedly installed between the front end of each guide sleeve and the bottom end of the lifting frame and internally provided with a transverse groove and a longitudinal groove communicating with the transverse groove; a sliding board is installed in a cavity of the lifting frame in a vertical sliding mode; the guide sleeves are internally provided with sliding grooves extending front and back; a sliding frame is installed inside each sliding groove in a sliding mode and internally provided with a groove allowing the corresponding guide rod to penetrate through; the rear end wall of each groove is an arc face; and each arc face is fixedly provided with an arc friction plate.

Description

technical field [0001] The invention relates to the construction field, in particular to a construction material transportation device. Background technique [0002] During building construction, it is often necessary to transport building materials from a low place to a high place. The traditional transportation method is to use a crane to lift after the sling is tied. And some electric lifting devices have potential safety hazards that the transportation cannot continue or the whole device will fall when the power is cut off. At this time, if there are people in the lifting cage, it is more likely to cause an accident. Contents of the invention [0003] The object of the present invention is to provide a construction material transportation device and its use method, which can overcome the above-mentioned defects of the prior art. [0004] According to the present invention, a construction material transportation device includes a base plate fixedly installed on the gro...
