Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a rotating structure and a rotating mechanism for a concrete pouring device. Background Art

[0002] With the acceleration of urbanization, the number of construction projects in cities is increasing. At present, high-rise buildings or large factory buildings usually adopt the method of concrete pouring. The main methods of concrete pouring are automobile pumps, fixed pumps and unpowered (string barrels, chutes, etc.) pouring. Automobile pumps are flexible in layout, have a large pouring coverage, and are widely used; fixed pumps have a large head. At present, one pump has been achieved for super high-rise buildings over 300m, and areas that cannot be poured by automobile pumps can also be reached. However, due to the position limit of the pump pipe, its position adjustment flexibility is poor, and the pouring method of moving the pump pipe during pouring is cumbersome. Although a placing machine can be added to solve some problems, there are also many requirements for the layout of the placing machine. Unpowered (string barrels, chutes, etc.) pouring has gradually been widely used due to its advantages such as faster pouring speed, cost saving, and low noise.

[0003] When using a chute to cast concrete, on the one hand, due to the influence of the chute processing and reinforcement, the concrete is likely to cause the displacement of the embedded reinforcement (parts) or formwork during the falling process, thus affecting the quality of the structure. In addition, the foundation of the chute is not firmly fixed, which can easily cause the chute to overturn and lead to safety accidents. On the other hand, the position of the chute needs to be frequently moved during the pouring process, which prolongs the time for concrete pouring.

[0004] Casting string barrel refers to a cylindrical object set up in the process of vertically conveying concrete to prevent concrete from segregation. Concrete slides down through it. The function of the string barrel is the same as that of the conduit and chute, which are all set up to convey concrete. Generally, the string barrel is directly connected to the delivery pipe of the pump truck on the construction site. Concrete segregation will occur when the free fall height exceeds 2 meters, so the concrete for pile foundations over 2 meters must be conveyed by conduits, string barrels or chutes. However, the traditional string barrel structure is relatively simple. The single-section string barrel is a barrel-shaped structure with a large top and a small bottom. The upper and lower sections of the string barrel are often connected by iron chains and hooks. The overall connection is relatively inconvenient, and it is a fixed connection with poor flexibility, and the pouring operation surface is limited.

[0005] Therefore, how to design a rotating structure that can be used for a concrete pouring device and a rotating mechanism of a concrete pouring device to increase the flexibility of the concrete pouring device has become an important issue facing those skilled in the art. Utility Model Content

[0016] Furthermore, the rotating structure is arranged at two ends of the rotating mechanism.

[0017] Furthermore, the rotating structure also includes a tripod and ear plates arranged on the outer wall of the outer steel pipe.
