Description

High-rise construction safety protection lift platform

Technical Field

The application relates to the field of high-rise protection lifting construction, in particular to a high-rise construction safety protection lifting platform.

Background

The construction safety protection lifting platform is temporary equipment for supporting and protecting constructors in high-altitude operation, can ensure the safety of the constructors, can prevent the constructors from falling from high places or being damaged by other injuries, is widely applied to the fields of buildings, bridges, maintenance, decoration and the like, provides a stable and safe working platform for the constructors, and improves the construction efficiency and working conditions.

The existing lifting platform mainly comprises a platform and related structures, a stable plane can be provided for a worker to stand, tools to store and work and execute, the lifting mechanical device is used for adjusting the height of the worker to be lifted to the working height, when the existing lifting platform is used for construction, the area of the lifting platform is small, so that constructors and working equipment which can only carry a part of the lifting platform can be caused, the construction efficiency is too low, in addition, the high-altitude construction is dangerous, and when some lifting equipment is used for construction in severe weather, the lifting equipment is very easy to skew, so that safety accidents are caused. Along with the development of technology, a great deal of optimization is performed on the lifting platform by technicians in the related field, and for more accurate comparison, a high-rise construction safety protection lifting platform is disclosed in Chinese patent with publication number of CN 218862042U;

When the scaffold is used, the hydraulic support is driven to stretch out and draw back through the mode of hydraulic oil injection, thereby driving the platform body to lift and move, the guardrail can shelter from the outside of platform body, provide the protection for the operation personnel, promote the baffle to drive the picture peg and remove to suitable position along the platform body, the distance between platform body and the picture peg is greater than the length of original platform body, the action scope of increase staff, the baffle drives the sleeve plate and removes to corresponding scaffold frame, the fly leaf receives the extrusion of scaffold frame and moves into the sleeve plate, make the space increase between the fly leaf get into fly leaf and sleeve plate until the scaffold frame gets into in, spring atress resilience promotes the fly leaf to reset, accomplish the connection with the scaffold frame, thereby realize fixing the picture peg, and reinforcing operation stability.

However, the high-rise construction safety protection lifting platform has some defects in the actual use process: 1. the device drives the platform to lift by using a hydraulic oil injection mode, the bearing capacity is lower, too much constructors cannot be transported to pass through construction materials in one lifting process, the construction efficiency is low, and the bottom supporting point of the lifting device is provided with a moving vehicle for supporting, even if the lifting platform can be connected with a scaffold, the safety of the constructors cannot be ensured in the construction process due to the instability of bottom bearing.

2. The device uses the hydraulic pressure to drive the platform to move, so that the lifting height is limited, too many constructors cannot be born to construct some high-rise buildings, the application range is limited, and the device is hydraulically driven, so that the supporting time of the device cannot be too long when the constructors are driven to perform high-altitude operation, the long-time construction requirement cannot be met, and the construction efficiency is further lowered.

3. Above-mentioned device is when driving constructor and goes up and down, and its lift platform guardrail height is too low all around for constructor can't be complete receive effectual protection in the lift process, has increased constructor and has taken place the probability that falls when the operation.

Thus, under the above stated point of view, there is room for improvement in existing high-rise construction safety protection lifting platforms.
