Description

Technical Field

[0001] This utility model relates to a chimney, and more particularly to a tower-type chimney that is easy to maintain. Background Technology

[0002] Chimneys include self-supporting chimneys, cable-stayed chimneys, and easily maintainable tower-type chimneys. Among these, the tower-type chimneys, which are easy to maintain, have a vertical truss tower that bears horizontal loads and can fully utilize the material properties. However, some easily maintainable tower-type chimneys lack a working platform, while others have a working platform fixed to the tower, which cannot be disassembled, raised, or lowered, indirectly increasing the manufacturing cost of the tower and making it inconvenient to use. Utility Model Content

The enclosed working platform slides vertically with the tower via a linear module. The enclosed working platform comprises several platform units arranged along the circumference of the tower, with adjacent platform units hinged end-to-end and disconnected at one hinge point. A locking device is installed at the disconnection point. Each platform unit consists of a top plate, an outer side plate, and an inner side plate, with the top plate and outer side plate, and the top plate and inner side plate, fixedly connected. The linear module includes vertical slide rails located at the four corners of the tower and rollers that cooperate with the vertical slide rails. The rollers are installed inside the platform units. A pulling mechanism for pulling the enclosed working platform is installed on the enclosed working platform.

[0006] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the tension mechanism includes a cable, a fixed pulley for the cable to pass over, and a winch installed on the enclosed working platform. Fixed pulleys and cables are provided at each corner of the tower. One end of the cable is fixed to the winch, and the other end of the cable is fixed to the enclosed working platform.

[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the outer edge of the enclosed work platform is provided with a fence.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: each platform unit is provided with two sets of rollers on its inner side, two rollers in each set, and the two sets of rollers are respectively located at the two corners of the tower, with the two rollers in each set arranged vertically.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: a roller mounting seat is fixed inside the platform unit, a roller movable seat is mounted on the roller, a movable rod is provided on the roller movable seat, and a slot is provided on the roller mounting seat to facilitate the insertion of the movable rod. A compression spring is provided in the slot and fitted on the movable rod to further improve the fit between the roller and the linear module. A limiting nut is provided on the part of the movable rod that protrudes from the slot, and a limiting ring of the compression spring is provided at the slot opening to facilitate the disassembly and assembly of the roller.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the vertical slide rail is a channel steel or I-beam, and the slide rail is formed by utilizing the structure of the tower itself.

[0011] Compared with existing technologies, this utility model, through its enclosed working platform, is suitable for the later maintenance and inspection of the chimney body, and is also convenient to assemble and disassemble. The inclusion of a linear module and a tension mechanism better enables the automatic lifting and lowering of the enclosed working platform, improving the flexibility of the device. Furthermore, the use of compression springs on the roller axles ensures better cooperation between the rollers and the slide rails. The tower-type chimney design described in this utility model, which facilitates maintenance, is reasonable, simple in structure, and more suitable for later maintenance of the tower.
