Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to an assembled full-rotation concrete pouring device and an assembled full-rotation concrete pouring system. 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] Existing concrete pouring devices mainly use conduits, string barrels or chutes for transportation, and their structures are relatively simple. Therefore, how to design an assembled full-rotation concrete pouring device and an assembled full-rotation concrete pouring system that can be flexibly constructed, which can directly transport (self-flow) concrete from the mixer truck to the designated pouring site through the device, and can be recycled, and the pouring process is green and environmentally friendly, has become an important issue facing technical personnel in this field.

[0013] Furthermore, the rotating structure includes an inner steel pipe outer ring, an outer steel pipe inner ring, and a plurality of steel balls arranged between the inner steel pipe outer ring and the outer steel pipe inner ring. The inner steel pipe outer ring and the outer steel pipe inner ring form two groups of concentric rings, one large and one small.
[0014] Furthermore, the conveying mechanism includes a receiving port, several steel pipes interconnected by flanges, and a discharge port, the receiving port is fixed to the first section of the steel pipe, and the discharge port is arranged at the end of the last section of the steel pipe.
[0015] Furthermore, the rotating structure is connected to the first section of the steel pipe of the transmission mechanism by a steel rope through an ear block arranged on the outer wall of the outer steel pipe, and the receiving port collects concrete flowing from the inner steel pipe of the rotating mechanism.
[0016] Furthermore, the end of the last section of the steel pipe is made into a bent pipe, or the end of the last section of the steel pipe is connected to a rubber pipe, or a chute is provided at the end of the last section of the steel pipe.
[0017] On the other hand, the utility model further provides an assembled full-rotation concrete casting system, which includes at least two assembled full-rotation concrete casting devices provided by the utility model, wherein the discharge port of one of the concrete casting devices is connected to the hopper of the other concrete casting device, so that the concrete flows to the designated casting area.
[0018] Through the technical solution provided by the utility model, the assembled full-rotation concrete pouring device provided by the utility model includes multiple layers of mutually connected collecting mechanisms, rotating mechanisms and conveying mechanisms; after the concrete is discharged from the mixer truck, it can be directly transported (by gravity) to the designated pouring location through the device, which can enhance the flexibility of the concrete pouring device, realize the full rotation of the concrete pouring device, and increase the working surface of concrete pouring.

[0026] It can be seen that the assembled full-rotation concrete pouring device provided by the utility model is respectively provided with a collection mechanism, a rotating mechanism and a conveying mechanism from top to bottom. Considering the energy dissipation angle requirements and the depth of foundation pit construction, the extension depth of a set of devices is limited.

For example, there can be more than one assembled full-revolving concrete casting device at the top, and the corresponding assembled full-revolving concrete casting device at the bottom can also be reasonably configured according to the configuration of the upper assembled full-revolving concrete casting device. In addition, in terms of levels, there can be more than two levels, and a three-level, four-level or other multi-level configuration can be achieved according to the construction depth, which is not limited here.
[0068] The assembled full-rotation concrete pouring device provided by the utility model has a simple structure, is easy to manufacture, has good sealing performance, and is highly flexible. It can realize the rotation of the string drum within the rotation radius, overcome the defect of poor pumping flexibility of a fixed pump, increase the flexibility of the concrete pouring device operation, and can be applied to various work sites. The assembled full-rotation concrete pouring system provided by the utility model can include at least 2 sets of assembled full-rotation concrete pouring devices, and the rotating parts of each set of assembled full-rotation concrete pouring devices can rotate 360°. During on-site construction, the pouring space can be viewed, and the upper device can be adjusted to rotate 180°. Multiple sets of devices are arranged at the bottom to dock with it, so that the largest concrete pouring work surface can be achieved, and it can be combined into a multi-stage system with good energy dissipation effect, and can realize concrete pouring of deeper foundation pits. The assembled full-rotation concrete pouring system provided by the utility model itself can be recycled, saving costs, and saving pumping fees, etc., with good economic benefits.
