Description

Technical Field

[0001] The invention relates to a construction machine, in particular to a special platform for a cylinder structure, which is applied to the decoration and maintenance of a well tube wall. Background Art

[0002] Nowadays, there are various hoists and lifting devices in construction machinery, which are widely used in construction, especially in the facade construction of high-rise buildings. The improvement of work quality and efficiency by lifting devices is particularly obvious. However, in the construction of cylindrical buildings such as shafts, such as the decoration and maintenance of their inner walls, there is no dedicated lifting equipment. Usually, only scaffolding can be built inside or a general hanging basket can be used, which has a great impact on the progress and quality of the entire project. Due to the limitation of the space inside the cylinder, the construction of scaffolding is inconvenient, inefficient and unsafe; in addition, there may be wall lamps or other raised obstacles on the inner wall of the cylinder, which need to be avoided in a targeted manner. The use of hanging baskets is not very applicable, and there are also hidden dangers in operating stability and safety. Summary of the invention

[0003] The purpose of the present invention is to provide a special platform for cylindrical structures, which is convenient for the construction and use of cylindrical structures, improves the safety and applicability of the machinery, and thus improves work efficiency.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A special platform for cylindrical structures, comprising:

[0006] A hanging support frame is fixed on the passage opening of the cylinder structure;

[0007] The tabletop assembly includes a middle platform, a fan-shaped side platform and a lap platform. The middle platform is polygonal in shape. A plurality of fan-shaped side platforms are installed correspondingly on the edge of the middle platform. The edge shape of the fan-shaped side platform is adapted to the inner wall surface of the cylinder structure. The lap platform is arranged between two fan-shaped side platforms corresponding to obstacles on the inner wall of the cylinder structure to achieve avoidance.

[0008] The driving device includes a hoist and a working wire rope. A hoist is arranged on each fan-shaped edge platform. The working wire rope is suspended on a suspension support frame. The hoist drives the corresponding working wire rope to wind and unwind, thereby driving the table assembly to lift and lower.

[0009] In particular, it also includes a safety device, which includes a safety wire rope and a safety lock. The safety lock is fixed to the table top assembly through a mounting frame, and the safety wire rope passes through the safety lock. When the lifting speed of the table top assembly exceeds the limit speed or the working wire rope becomes loose or even breaks, the safety lock clamps the safety wire rope to stop the table top assembly.

[0010] In particular, a contact switch is arranged on the mounting frame, and an upper limit block is arranged on the safety wire rope. When the contact switch touches the upper limit block, the table assembly reaches the upper limit position.

[0011] In particular, a plurality of countertop assemblies are provided, and the plurality of countertop assemblies are fixedly connected up and down by a connecting frame, and an access hole is opened on the middle platform of the upper countertop assembly, and a ladder extending to the lower countertop assembly is provided on the access hole.

[0012] In particular, the edges of the sector-shaped side platform and the middle platform are abutted against each other and fastened by bolts.

[0013] In particular, the overlapping platform is overlapped and fixed with the fan-shaped edge platforms on both sides.

[0014] In particular, guardrails are provided at the edges of the fan-shaped edge platform and the overlapping platform.

[0015] In summary, the beneficial effect of the present invention is that, compared with the prior art, the dedicated platform for the cylindrical structure is provided with a specially shaped table top component so as to adapt to the cylindrical structure and avoid obstacles on its inner wall. It is easy to build and has strong applicability. A driving device and a safety device are provided to ensure stable and reliable operation of the table top component, high safety, and convenient construction for personnel.
