Description

Technical Field

[0001] The utility model belongs to a protective operating platform for a building construction elevator shaft frame, in particular to a rotatable protective operating platform for the elevator shaft frame. Background Art

[0002] As a crucial component of high-rise building construction, elevator shaft safety is crucial during construction. Traditionally, elevator shaft construction involves erecting scaffolding on the inner walls of the shaft and then setting up a construction platform on top. Construction workers stand on the platform and work with the shaft's internal formwork. This often presents safety hazards, such as unstable operating platforms and inadequate protective measures, which can easily lead to falls and other accidents. Furthermore, with the rapid development of high-rise buildings, the volume of elevator shaft construction is increasing. Traditional construction methods present challenges such as complex setup and difficult disassembly, which not only impacts construction efficiency but also increases costs. Therefore, we propose a reusable elevator shaft protective operating platform to facilitate elevator shaft construction and address these issues. Utility Model Content

[0003] The purpose of the utility model is to provide a rotatable elevator shaft frame protection operating platform, which has a reasonable structure and can solve the safety hazards such as unstable platform and insufficient protection in the prior art. It is easy to assemble and disassemble, and improves work efficiency.

[0004] The object of the utility model is achieved as follows: a rotatable elevator shaft frame protection operating platform, including an elevator shaft in a high-rise building, two sets of hinged points of two sets of hinged secondary scissor-type lifting arms are respectively connected as a whole through an intermediate hinge shaft to form a secondary scissor-type lifting frame, two positioning hinged arms at the lower end of the secondary scissor-type lifting frame are hinged with corresponding lower supports provided on the base, two movable hinged arms at the lower end of the secondary scissor-type lifting frame are hinged with the lower hydraulic cylinder piston rod fixed on the base, two positioning hinged arms at the upper end of the secondary scissor-type lifting frame are hinged with corresponding upper supports provided on the bottom surface of the operating platform, two movable hinged arms at the upper end of the secondary scissor-type lifting frame are hinged with the upper hydraulic cylinder piston rod fixed on the bottom surface of the operating platform, horizontal telescopic rod devices are respectively fixed on the symmetrical elevator shaft walls, and the ends of the telescopic rods of the horizontal telescopic rod devices are respectively matched with the second-stage shear handles on the front and rear sides of the secondary scissor-type lifting frame.

[0005] The utility model is installed in an elevator shaft and includes: a base, which is fixed to the foundation by bolts; a secondary scissor lift is provided above the base; a platform is provided above the secondary scissor lift; a horizontal telescopic support rod device is symmetrically provided on the outside of the secondary scissor lift between the base and the operating platform; fences are provided on the four sides of the operating platform to improve safety.

[0006] The two-stage scissor lift frame includes two symmetrically arranged two-stage scissor lift arms. The top ends of the two two-stage scissor lift arms are connected to the upper hydraulic cylinder, which is connected to the bottom of the operating platform. The bottom ends of the two scissor lift arms are connected to the lower hydraulic cylinder and the fixed shaft, which are connected to the base. The lifting height of the operating platform is determined by adjusting the two-stage scissor lift arms through the upper hydraulic cylinder and the lower hydraulic cylinder.

[0007] A support shaft is fixedly connected between the second-stage scissor handles of the two secondary scissor lift arms. Specifically, the intermediate hinge shaft between the secondary scissor lift arms provides stability and safety for the secondary scissor lift frame.

[0008] Horizontal telescopic rods are symmetrically positioned on the outside of the two symmetrically positioned scissor-style lift arms, bolted to the elevator shaft wall. This secure connection provides a stable support base for the operating platform, significantly reducing the risk of accidental falls for construction workers. The rods' design allows for adjustment to the actual shaft wall, ensuring a secure connection regardless of size, shape, or material. Beneficial effects

[0009] This utility model adopts a modular design, consisting of multiple units that can be spliced ​​and fixed vertically and horizontally through standardized interfaces. This allows for adjustment and assembly to suit the size, shape, and construction requirements of different elevator shafts, enhancing the platform's adaptability and flexibility. Furthermore, through scientific and rational structural design, such as the use of a horizontal telescopic rod, the protective operating platform remains stable under construction loads, reducing safety risks associated with structural instability.

[0010] The utility model is easy to assemble and disassemble, which can significantly improve construction efficiency and shorten construction period. At the same time, its reusable nature reduces material waste and labor costs, further improves economic benefits and reduces construction costs for enterprises. BRIEF DESCRIPTION OF THE DRAWINGS
