The invention discloses a self-adaption magnetic resistance slow-falling device for a building hoist. The slow-falling device comprises a force bearing outer wall, a slow-falling rail and a permanent magnet. The permanent magnet is fixedly installed on the force bearing outer wall. A separation distance is set between the permanent magnet and the slow-falling rail. The slow-falling rail is installed on a tower frame in the length direction. The force bearing outer wall is installed on a hoisting cage in the length direction through a plurality of hinge mechanisms. Each hinge mechanism comprises a movable hinge and a limiting stop piece, wherein one end of the movable hinge is hinged to the force bearing outer wall, the other end of the movable hinge is hinged to the hoisting cage, the limiting stop piece is installed on the hoisting cage and used for limiting the movable hinge to rotating around the hoisting cage within a certain angle so that the separation distance between the permanent magnet and the slow-falling rail can be changed within a certain range. The slow-falling device is started immediately, it is guaranteed that the hoisting cage can fall to the ground at a safe and uniform speed, and safety accidents caused by the falling of the hoisting cage can not happen.
Description
technical field [0001] The invention relates to a vertical transport machine used in the field of building construction, in particular to an adaptive magnetic resistance fall-down device used for a construction elevator in the construction process. Background technique [0002] Construction elevators are often called construction elevators. They are machines used for vertical transportation of people and goods during construction. They are widely used in the construction of industrial or civil buildings, bridges, chimneys, shafts and other structures. One of the indispensable equipment in the process. The use of construction elevators can greatly reduce the labor intensity of construction personnel, speed up the progress of the project, and improve work efficiency, which plays a vital role. The construction hoist itself is equipped with multiple electronically or mechanically controlled safety devices such as anti-drop safety devices, speed limiters, buffer springs, and upp...
