Problems solved by technology
For construction companies, the construction method and construction safety issues of elevator shafts are becoming more and more prominent. The traditional method is to build fastener-type steel pipe scaffolding in the elevator shaft. The sealing protection work of this method will be impossible due to the existence of the operating frame. Timely protection in place has brought hidden dangers to safe production

The invention relates to a lifting platform, and discloses a rapid lifting platform for elevator shaft construction. The platform involves an elevator shaft, and is characterized in that the lifting platform is arranged in the elevator shaft, and the lifting platform further comprises a lifting mechanism arranged in the elevator shaft and used for controlling lifting of the lifting platform, a driving mechanism arranged at the top end of the elevator shaft and used for driving the lifting mechanism to operate, and a safety protection mechanism arranged on the lifting mechanism. According to the lifting platform, through the arrangement of a movable pulley assembly, the tensile force borne by a steel cable in the lifting process of the lifting platform is reduced, the use strength of the steel cable is enhanced, and the practicability of the device is improved; the device induces the acceleration of the lifting platform through a spring oscillator assembly, when the acceleration of the lifting platform is larger than a safety value, the spring oscillator assembly releases locking of a crank sliding block assembly, the crank sliding block assembly released from locking rotates and extends out under the action of a spring force storage assembly, safety protection is conducted on the lifting platform, and the safety of the device is improved.
Description
technical field [0001] The invention relates to a lifting platform, in particular to a fast lifting platform for elevator shaft construction. Background technique [0002] Elevators are an indispensable and important vertical transportation tool for high-rise buildings. With the rapid development of the national economy, urban land resources continue to decrease, and there are more and more high-rise and super high-rise buildings. In recent years, the height of high-rise buildings in many areas is basically above 100m, and some high-rise buildings even exceed 200m. For construction companies, the construction method and construction safety issues of elevator shafts are becoming more and more prominent. The traditional method is to build fastener-type steel pipe scaffolding in the elevator shaft. The sealing protection work of this method will be impossible due to the existence of the operating frame. Timely protection in place has brought hidden dangers to safe production. ...
