Description

Lifting platform for building construction Technical Field The utility model relates to the technical field of lifting platforms for building construction, in particular to a lifting platform for building construction. Background In the field of modern building construction, the lifting platform is used as important auxiliary equipment for high-altitude operation, and the safety performance and the operation reliability of the lifting platform are directly related to the life safety of constructors and the smooth progress of engineering projects. With the increasing complexity and high rise of building structures, higher requirements are put on the stability, bearing capacity and safety guarantee of lifting platforms. The lifting platform for construction is widely applied in the current building industry, and a core driving mechanism of the lifting platform mainly depends on a screw transmission system. The transmission mode utilizes a motor to drive a screw rod to rotate, converts rotary motion into linear lifting motion of the platform through a screw pair, and maintains static stability of the platform at any height by means of self-locking characteristic of screw threads of the screw rod. The screw transmission system becomes a main technical route of the lifting platform due to the advantages of simple structure, accurate control, static self-locking and the like. However, the design scheme of the single-dependent screw transmission has obvious potential safety hazards that when screw threads weaken self-locking capacity due to long-term abrasion, or under abnormal working conditions such as sudden load, severe vibration and the like, a single screw system can not provide sufficient safety redundancy, and once the screw or related transmission components fail, the platform is directly caused to fall out of control, so that serious safety accident risks are formed. Particularly in the high-altitude construction environment of the building, the platform usually bears personnel and a large amount of building materials, the design concept lacking multiple safety guarantee can not meet the increasingly strict safety standard and regulation requirement of modern building construction, and the design concept becomes a technical bottleneck for restricting the lifting platform to be applied to safety improvement.
