Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a vertical shaft hoisting device. Background Art

[0002] A vertical shaft is a well-shaped pipe with upright walls, essentially a collapsed funnel. Its planar profile is square, elongated, or irregularly circular. Its walls are steep and nearly vertical. Vertical shafts are widely used in water conservancy and hydropower projects for water intake, diversion, ventilation, slag removal, and air supply. Vertical shaft construction is characterized by its small footprint and minimal interference with surrounding construction. However, the limited space required for vertical shaft construction, long construction periods, frequent climbing and sidewalk work, and inconvenient access lead to significant safety risks in vertical shaft construction. Vertical shafts can be classified according to their diameter, cross-sectional shape, and depth.

[0003] During traditional vertical shaft construction, wire rope lashing and lug hoisting are widely used as the primary lifting and installation methods. While this traditional hoisting method has played an important role in past mine construction, its operation is cumbersome and inefficient, causing numerous construction inconveniences. Specifically, during wire rope lashing, the center of gravity of the load must be precisely measured and determined. The wire rope is then securely fastened to the load through a complex lashing process. This requires not only advanced skills and extensive experience, but also significant time and manpower. Subsequently, during the rope threading process, workers must thread the heavy wire rope through various lifting equipment and structural components. This process not only requires tremendous physical effort but is also fraught with safety risks. Improper operation can cause accidents such as wire rope breakage or detachment. The installation position of the lugs requires precise calculation to ensure stability and safety during the hoisting process. In practice, the installation and alignment of the lugs is extremely difficult due to the confined space and insufficient light inside the shaft, as well as the often large and irregularly shaped loads. A lot of time is often spent on fine-tuning operations such as pulling ropes and rotating to ensure that the hoisted object can reach the intended location accurately. In addition, both hoisting methods are particularly difficult when aligning the ladder position.

[0004] Therefore, there is an urgent need for a vertical shaft hoisting device to solve the problems of difficult construction and low construction efficiency of traditional wire rope binding hoisting and lug hoisting. Utility Model Content

[0005] In view of this, the utility model proposes a vertical shaft hoisting device, which aims to solve the problems of laborious construction and low construction efficiency of traditional wire rope binding hoisting and lug hanging hoisting.

[0018] Furthermore, each first support arm includes at least one rod, each second support arm includes at least two rods, and the first support arm at the connection between the first support arm and the second support arm is arranged in the middle of the second support arm.

[0019] Furthermore, the activity block includes:

[0039] It is understood that when the device is installed in the vertical shaft, it can be hoisted with the help of excavators, loaders, cranes and other machinery on the construction site, which is convenient and fast. The top of the device adopts a single lifting point structure, namely the lifting ring 400. Only one lifting ring 400 is needed to complete the lifting of the vertical shaft. During the installation process, the orientation and angle of the vertical shaft are easily rotated, and the adjustment is convenient, which facilitates the alignment of the upper and lower sections, ensuring the smooth progress of the lifting process. The device only needs to be placed vertically inside the vertical shaft, and the friction between it and the inner wall of the vertical shaft can be used to lift the vertical shaft quickly, safely and efficiently. During lifting, the telescopic support frame 200 forms an independent triangular stable structure with the inner wall of the vertical shaft when it falls freely. When the hoist is lifted, the reverse support force of the telescopic support frame 200 can be firmly locked with the wall of the vertical shaft, realizing the safe lifting of the vertical shaft. The heavier the vertical shaft, the greater the support force of the support arm, which effectively improves construction efficiency. In summary, the present invention has a simple structure, low production costs, extremely low subsequent maintenance costs, and is recyclable, resulting in a high cost-effectiveness ratio.

When the bent part, that is, the corner part, of the triangular support arm 220 is against the inner wall of the vertical shaft, the movable block 230 is fixed by the fixing assembly 300, and the friction between the triangular support arm 220 and the inner wall of the vertical shaft can be used to lift the vertical shaft quickly, safely and efficiently. During lifting, the telescopic support frame 200 falls freely to form an independent triangular stable structure with the inner wall of the vertical shaft; when the hoist is lifted, the reverse supporting force of the telescopic support frame 200 can be firmly locked with the wall of the vertical shaft, thereby realizing safe lifting of the vertical shaft, with simple device and strong stability.

[0052] In a specific embodiment of the present application, the horizontal area of ​​the fixing block 210 is larger than the horizontal area of ​​the main rod 100 .

[0053] It can be understood that the horizontal area of ​​the fixed block 210 is larger than the horizontal area of ​​the main rod 100, which can make the connection between the main rod 100 and the fixed block 210 more stable, ensure the connection stability of the triangular support arm 220, and thus ensure the supporting force of the telescopic support frame 200 for the vertical shaft.
