Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a construction elevator with a suspended bottom support. Background Art

[0002] In construction, construction elevators are indispensable vertical transportation tools, whether it is high-rise building construction or underground well construction. At present, during the construction of high-rise buildings, elevators are generally placed in the elevator shaft reserved inside the building, and the guide device used with the elevator also uses conventional elevator standard sections. The elevator standard section needs to be fixed to the wall. Therefore, the transportation height of the commonly used elevators is limited by the construction concrete structure layer and cannot be transported to the construction space above the structure layer. When performing top formwork construction above the structure layer, it is often necessary to build additional stairs, but it is time-consuming and laborious for construction workers to walk back and forth on the stairs, which greatly reduces the construction efficiency.

[0003] Patent 2011100328173 discloses a self-elevating construction elevator, a self-elevating construction elevator, including a car, an elevator power system located above the car, a steel wire rope connected between the car and the elevator power system, and an elevator guide device connected to the car, the elevator power system is placed in an elevator machine room, the elevator machine room is located on the upper part of the structural construction layer and is fixed on a steel platform on the top of the high-rise building under construction; the elevator guide device includes a moving frame, connecting embedded parts, elevator guide rails and guide rail brackets; the upper part of the elevator guide rails is located in the moving frame and the upper end of the elevator guide rails is located above the steel platform, and the lower part of the elevator guide rails is located in the core tube elevator shaft.

[0004] Although the above device can improve the operating range of the construction elevator, each time the steel platform rises, the mobile frame rises together with the elevator room and the steel platform, and the elevator guide rail is disconnected between the lower part of the mobile frame and the upper part of the guide rail bracket. After the mobile frame stops lifting, the elevator guide rail at this location is added according to the lifting height. It is very troublesome during construction, and the car is suspended, which is prone to slippage and poses certain safety hazards. Utility Model Content
