Background technique

Construction elevators are also called construction elevators for buildings, and can also be used as outdoor elevators to lift cages on construction sites. Construction elevators are mainly used in various urban high-rise and super-high-rise buildings, because such building heights are very difficult for the use of well-frames and gantry to complete the operation. It is a manned and cargo construction machine often used in buildings, mainly used for the interior and exterior decoration of high-rise buildings, the construction of bridges, chimneys and other buildings. Because of its unique box structure, it is comfortable and safe for construction workers to ride. The construction hoist is usually used in conjunction with the tower crane on the construction site, because with the height of the floor, the construction hoist needs to be disassembled and pulled up to a higher floor, that is, the construction hoist is increased and then assembled and put into use again. In this process It is necessary to disassemble and reassemble the traction system, car, etc.

The rope head rod combination structure is a transitional mechanism that connects the traction wire rope to the car and the counterweight device or connects the traction machine load-bearing beam and the rope head plate girder in the traction system. Most rope head rod combination structures are The steel wire rope passes through the taper sleeve, and the wire rope will be locked due to the combined structure of the rope head and rod. If the length of the wire rope needs to be adjusted, the wire rope can only be replaced, resulting in inconvenient installation and increased cost. Although there are also some adjustable and locked rope heads Rod structure, but this type of rope head rod is to pass the wire rope through the roller and then fix the bent wire rope head through the locking piece, which will cause great damage to the wire rope. More importantly, in the old-fashioned structure, it is necessary to loosen the wire ropes at each rope head rod one by one and then put on a longer length of wire ropes, which is undoubtedly time-consuming, labor-intensive and complicated to operate, which prolongs the lifting time. , which affects the construction period.
