Description

Technical Field

[0001] The utility model belongs to the technical field of lifting equipment, and in particular provides a lifting platform. Background Art

[0002] The mining and smelting industry requires the use of many different types of smelting furnaces, among which the vertical furnace is one of the most common types.

[0003] Taking the CDQ oven as an example, during its operation, red-hot coke is pushed out of the coke oven and loaded into the oven's top via a coke loading device, where it then enters the oven. Circulating air is then delivered to the oven's bottom by a circulating fan, flowing upward and countercurrently into contact with the red-hot coke, completing the heat exchange process. The cooled coke is discharged from the CDQ oven via a coke discharge device and then onto a belt conveyor system for final transport to the ironworks. During this process, the refractory materials within the oven must withstand frequent temperature fluctuations and the erosion of coke. Consequently, the refractory materials within the oven require a minor overhaul approximately every one to two years and replacement every three to five years on average.

[0004] All of these maintenance operations require deep access to the furnace interior, requiring the construction of scaffolding as a working platform. Setting up the scaffolding typically takes 3-5 days, while dismantling it takes another 2-3 days. Clearly, this scaffolding-building and dismantling work is time-consuming and labor-intensive, significantly impacting the project schedule.

[0005] At present, there are some modular scaffoldings on the market, but they are constrained by the structure of the furnace and the construction sequence (1. The size of a single module is limited; 2. The top structure needs to be completed after the bottom structure is completed before it can be built). As a result, the overall lifting and splicing process still takes 2-4 days, and the construction period is still relatively long. Utility Model Content

[0010] The frame is provided with a first assembly anchor point, a second assembly anchor point and a third assembly anchor point. The first assembly anchor point is used in pairs with the first auxiliary cable connection seat, and the cable assembled between the first assembly anchor point and the first auxiliary cable connection seat is in a vertical state. The third assembly anchor point is used in pairs with the second auxiliary cable connection seat, and the cable assembled between the third assembly anchor point and the second auxiliary cable connection seat is in an inclined state.

[0013] Furthermore, the sleeve is formed by splicing a plurality of frame bodies, and the frame bodies are arc-shaped.

[0014] Furthermore, the power mechanism is an electric hoist, which is assembled with a lifting chain and a sleeve.

[0015] Furthermore, the pillar is composed of a top section, a middle section and a bottom section, the top section, multiple middle sections and the bottom section are connected end to end in sequence, and straight ladders are provided inside the top section, the middle section and the bottom section.

[0016] Furthermore, a plurality of tripod mounting seats are evenly arranged on the bottom of the support side wall, the tripod mounting seat is fixedly connected to one end of the tripod, and the other end of the tripod is fixedly connected to the bottom of the external furnace body or the ground.

[0017] Furthermore, a tensioner is provided at the middle of each connecting cable.

[0018] The beneficial effects of using the utility model are:

[0019] The structure of this lifting platform can fully utilize the space inside the furnace, and only requires minor adjustments to the size of the accessories. The overall structure can be adapted to a variety of different furnace types, making it more flexible and convenient to use.

[0020] Abandoning the inherent thinking of scaffolding, the system adopts a central pillar load-bearing method and a ring platform lifting method, which greatly reduces the modules that need to be assembled and the space occupied in the furnace after construction. In addition, all the spare parts are common parts that can be purchased on the market, making the manufacturing process controllable and conducive to promotion.
