Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction, and specifically relates to a building construction safety protection lifting system. BACKGROUND

[0002] In the building construction scene, construction safety is always the top priority. With the continuous expansion of building project scale and the continuous rise of building height, the performance and reliability of construction safety protection equipment are increasingly demanding. Especially in the vertical transportation of personnel and materials, the safety and reliability of the safety protection lifting system directly affect the smooth progress of construction and the safety of personnel and property. Reviewing the traditional building construction safety protection lifting system, it has significant defects in many key aspects. In terms of structural design, the column unit usually adopts a simple and single structure, lacking a stable combined structure. For example, the traditional column unit is usually a single or a small number of steel pipes simply spliced, which has poor integrity. When facing long-term and high-intensity construction use, it is prone to deformation and shaking, which not only seriously interferes with the stable operation of the lifting system, but also may cause safety accidents and endanger the lives of construction personnel. In terms of power transmission, the connection between the power mechanism and the lifting cage in the traditional system is very rough. The power mechanism is usually a simple single motor drive, and the connection with the lifting cage lacks precise transmission design, resulting in large power transmission loss, low efficiency, and unstable lifting process. At the same time, due to the lack of effective limiting and stabilizing devices, the lifting cage shakes obviously during lifting, further increasing the safety risk and reducing the reliability of the system.

[0003] Furthermore, in the fixed link with the construction building, the traditional protective fixed support has poor design flexibility and is difficult to adapt to complex and diverse building structures and construction environments. Whether it is faced with special needs in different construction stages or special-shaped building structures, the traditional support cannot ensure that the column unit and the building main body are connected stably and reliably, which undoubtedly poses a safety hazard to the entire lifting system. In addition, the safety cage and the lifting cage also have deficiencies in protection facilities. The movable door design is usually a simple opening and closing structure, which is inconvenient to operate and has a simple safety locking mechanism, and is prone to accidental opening during construction. The top of the lifting cage often does not have a reasonable access hole, making equipment maintenance and repair work difficult, which is not conducive to timely detection and elimination of potential faults. SUMMARY

[0004] Therefore, in order to solve the above-mentioned deficiencies, the utility model provides a kind of building construction safety protection lifting system.Compared with the prior art, the building construction safety protection lifting system is comprehensively optimized by innovative design.The column unit is vertically overlapped and connected by multiple column segments, each segment is connected by four groups of steel pipe columns, and is connected with the I-shaped metal frame and the connecting reinforcing rib to form a stable three-dimensional structure, which greatly improves the overall stability.Meanwhile, vertical racks are arranged on both sides of the column unit, and two groups of motors and reduction mechanisms drive the transmission gears to realize efficient and stable power transmission.The channel steel frame is tightly matched with the steel pipe column through the limiting channel steel and the limiting wheel, which significantly reduces the shaking of the lifting cage.The front and rear support bolts of the protection fixing support are connected, and the positioning seat and the metal frame are respectively and stably connected with the construction building and the column unit, which enhances the connection reliability of the system and the building.The reasonable design of the movable door and the access hole further improves the safety and maintainability of the system.
