Construction hoist for underground engineering

Abstract

The invention provides a construction hoist for underground engineering. The construction hoist for underground engineering comprises a supporting frame and a lifting box unit. The supporting frame is of a cylinder structure, a guide rail is arranged on the supporting frame, and the guide rail is parallel to the axis of a cylinder. The horizontal cross section of the lifting box unit is in a shape of a section ring, the lifting box unit comprises a top plate, a base plate, a first side plate, a second side plate, a large arc-shaped side plate and a small arc-shaped side plate, the first side plate and the second side plate are rectangular, a pulley is arranged on the small arc-shaped side plate, driven by a motor and installed on a track, a connecting plate is arranged on the base plate of the lifting box unit and is hinged to the base plate under a single door on the second side plate. The connecting plate is smaller than the second side plate in width, and the length of the connecting plate is larger than the distance between two lifting boxes. The construction hoist can independently ascend and descend, can be connected together for joint operation and is simple in structure, convenient to use, and a large amount of working time is saved.

Description

technical field [0001] The invention relates to a construction hoist for underground engineering. Background technique [0002] An elevator is a lifting mechanical device or device for a platform or a semi-enclosed platform for carrying people or goods up and down vertically. In the construction of underground projects, it is often necessary for the elevator to carry skilled workers into the underground passage. The traditional elevator is generally designed as a single body, and its platform is too large. When workers need to return to the ground, they often climb up and down the support frame, or stop working and pass through. The elevator carries it back, wasting labor time. Contents of the invention [0003] The problem to be solved by the present invention is to provide a construction elevator for underground engineering, the elevator is provided with a plurality of lifting boxes, which can realize independent up and down, and the lifting boxes can be connected to ea...
