Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide a magnetic resistance slowing device for construction elevators, which can ensure the safety of construction elevators in real time. When problems such as untimely maintenance, irregular operation, and overloading lead to the failure of the safety protection device of the construction hoist, the invention will start immediately. The cage can be lowered to the ground at a safe and uniform speed to avoid safety accidents caused by the fall of the cage

The invention discloses a magnetic resistance slow-falling device for a building hoist. The magnetic resistance slow-falling device is installed between a tower frame and a hoisting cage of the building hoist. The hoisting cage can move in the length direction of the tower frame. The magnetic resistance slow-falling device comprises a force bearing outer wall, a slow-falling rail and a permanent magnet. The slow-falling rail is made of a nonferromagnetic material. The permanent magnet is arranged between the force bearing outer wall and the slow-falling rail. 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. Of the force bearing outer wall and the slow-falling rail, one is installed on the tower frame in the length direction, and the other one is installed on the hoisting cage in the length direction. By means of the magnetic resistance slow-falling device, the safety of the building hoist can be guaranteed in real time, when a safety guaranteeing device of the building hoist fails, 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 a magnetic resistance slow-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 upper and low...
