Abstract
Description
Technical Field
[0001] This invention relates to cement kiln construction equipment, and more particularly to a suspended lifting platform used in the construction of vertical pipeline structures. Background Technology
[0002] Currently, during the construction of blast furnaces, hot blast stoves, and other furnace bodies, the typical construction sequence is to first install the furnace shell and frame structures, followed by the installation of cooling and furnace roof equipment. When installing the internal water-cooled walls, carbon brick and refractory brick masonry, or spraying, the traditional construction method involves erecting a custom-designed suspended platform layer by layer, suitable for cyclone furnaces and limestone vertical kilns. Designed for different diameters, sizes, and loads, the platform can be assembled on the surface or lowered from the top opening after assembly. The platform is designed for operation by a person simply standing on it.
[0003] Publication No.: CN120867510A A furnace equipment installation and operation platform and construction method are described. The operation platform includes: main beams, radially uniformly arranged, with the center end of each main beam welded and fixed to a central fixed steel plate; top supports, installed on the outer ends of each main beam, capable of telescopic movement on the main beams; support beams, set between each main beam; treads, laid on the main beams and top supports; temporary lifting lugs, welded to the upper edge of the furnace top plate; and an electric hoist, with one end of its chain connected to the temporary lifting lug and the other end connected to the main beam, its sprocket set at a height easily accessible to construction personnel on the platform. The construction method involves fixing the operation platform to the upper edge of the already constructed furnace shell, and using the electric hoist to lift the operation platform layer by layer on the furnace shell for the installation of furnace equipment.
[0004] The aforementioned comparative documents exhibit shortcomings such as poor main load-bearing capacity, limited specified controllable diameter, and low controllability and safety. Summary of the Invention
[0005] The purpose of this invention is to provide a suspended lifting platform for use in the construction of vertical pipeline structures. This is a custom-designed suspended platform suitable for cyclone separators, limestone vertical kilns, and steel furnaces. It is designed for different diameters, sizes, and loads. The platform can be assembled on the surface or lowered from the top opening after assembly. The platform is designed for operation by a person on it during the construction of vertical pipeline structures.

[0007] The aforementioned mounting pedal structure includes a central mounting pedal located on the central connecting frame structure, a peripheral mounting pedal located between the outer connecting frame structure and the central connecting frame structure, and an outer edge mounting pedal located on the outer side of the outer connecting frame structure.

[0009] The center mounting pedal, the outer mounting pedal, and the upper part of the outer edge mounting pedal are all provided with anti-slip texture.
[0010] The central connecting frame structure includes a first pipe fitting connecting angle seat that is spliced into a hexagon and connects adjacent central connecting rods. The outer end connecting frame structure includes an outer end connecting rod group that is spliced into a hexagon and a second pipe fitting connecting angle seat that connects adjacent central connecting rods. The first pipe fitting connecting angle seat and the second pipe fitting connecting angle seat are arranged radially perpendicularly.
[0011] Each outer end limit rod assembly is equipped with a polyurethane corner wheel on its outer side.
[0012] The beneficial effects of this invention are as follows: The structure is typically designed with a net load of 6000 lb, using 6 hooks (the number may vary depending on customer requirements). All structural components are made of aerospace-grade aluminum (6061-T6), with a minimum safety factor of 4:1. Hook installation is simple, and the space around the hooks allows all cables to be cleared from the work platform. The platform is easy to control with buttons. The lifting platform adopts a modular design, making assembly convenient. All individual components weigh less than 50 lb and are no longer than 10 inches (assembly can be completed in 1 hour). (Electric hooks weigh 100 lb each). Three lever switches control polyurethane corner wheels installed at different positions under the platform to maintain platform stability and protect newly laid refractory bricks.
