Description

Technical Field

[0001] This utility model relates to the field of concrete chute technology, and in particular to a movable branched concrete pouring chute. Background Technology

[0002] In large-scale concrete construction fields such as building engineering, concrete transportation and pouring are key links that directly affect project quality, construction efficiency and cost. Currently, commonly used concrete transportation methods mainly include concrete pumping, tower crane hoisting, belt conveyors and traditional simple chutes.

[0003] During the concrete pouring process of the wind turbine foundation, due to the influence of the mountainous terrain, the foundation is too close to the slope, making it impossible for multiple overhead pumps to operate simultaneously. Moreover, the cost of pouring with multiple overhead pumps is high, and large-volume concrete needs to be poured continuously and quickly in a short period of time.

[0004] Based on this, a movable bifurcated concrete pouring chute is proposed to effectively solve the problem of rapid and efficient pouring of large-volume concrete for wind turbine foundations. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a movable bifurcated concrete pouring chute.

[0006] The technical solution to achieve the purpose of this utility model is: a movable branched concrete pouring chute, including a chute body and a support body.

[0007] The chute body is composed of a chute upper part, a chute middle section and a chute lower part that are connected in sequence.

[0008] The support body includes a frame made of welded steel bars and movable wheels installed at the bottom of the frame. The chute body is fixedly installed on the support body through connectors.

[0009] In some embodiments, the chute body is made of templates, and the templates are reinforced and connected by steel bars.

[0010] In some embodiments, the frame of the support body is welded from steel bars, the movable wheel is a wooden roller, and the end of the support leg of the support body passes through the central shaft hole of the movable wheel.

[0011] In some embodiments, the connector is a connecting wire that passes through the template of the chute body and is tied and fixed to the reinforcing bars on the support body.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model, through the design of a three-pronged chute at the bottom, can simultaneously distribute a stream of concrete to three different working faces, realizing synchronous and continuous pouring on multiple working faces. It completely solves the problem of low efficiency caused by the frequent movement and alternating pouring of traditional single chute or pump truck. It is particularly suitable for large-volume concrete projects that require one-time continuous molding, greatly shortening the construction cycle.

[0014] Secondly, this utility model is mainly composed of ordinary templates, steel bars and simple moving wheels. It has low manufacturing cost and uses the self-weight of concrete for flow transportation without any external power source, thus saving fuel or electricity consumption. It is highly adaptable and does not require the construction of special platforms or roads for large equipment in narrow or complex terrain (such as the foot of a mountain slope), thus saving earthwork and leveling costs.

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved movable branched concrete pouring chute. The technical solution of this utility model is as follows:

[0022] like Figures 1-2As shown, a movable, branched concrete pouring chute includes a chute body and a support body 1. To balance lightweight, low cost, ease of processing, and sufficient wear resistance, the chute body is preferably constructed using high-quality waterproof multi-layer wooden boards as formwork 6. The joints of the formwork 6 are reinforced with round steel or threaded steel bars 8 to ensure that the chute does not deform or fall apart under the impact of concrete. The inner wall of the chute should be polished smooth and can be coated with a release agent or wrapped with a thin sheet of iron to further reduce frictional resistance and extend service life. The chute body is the channel for concrete flow, and its core function is to receive, transport, and divert concrete. The chute body consists of a chute upper section 3 connected in sequence, with the upper section 3 serving as the feeding section. The inlet is funnel-shaped or straight trough-shaped, used to receive concrete unloaded from concrete transport trucks. Its design ensures that concrete can enter the chute system smoothly and centrally, reducing splashing. The middle section 4 of the chute, the main conveying section, connects the upper and branch sections. Its main function is to extend the total length of the chute, expand the pouring radius, and accelerate and stabilize the concrete flow under gravity, preparing for subsequent diversion. This section, along with the lower three-branched chute 5, is the core functional section and is crucial for achieving simultaneous pouring on multiple work surfaces. Its structure transitions from one inlet to three outlets at certain angles. This design can evenly and smoothly divide a concentrated concrete flow into three streams, guiding them to different predetermined areas of the foundation pit, thus achieving a highly efficient operation mode of single-point feeding and simultaneous three-point discharge.

[0023] The support body 1 includes a frame constructed from welded steel bars 8 and casters 2 mounted on the bottom of the frame. The chute body is fixedly mounted on the support body 1 via connectors. To ensure support strength and economy, the entire frame is constructed from welded threaded steel bars 8. All connection nodes are fully welded to ensure overall rigidity and durability. The casters 2 can be solid rubber wheels or rubber-coated cast iron wheels, or even hardwood wheels with a central hole, directly fitted onto the support legs of the steel bars 8 that serve as axles. The structure is simple and inexpensive.

[0024] like Figure 1 and Figure 2 As shown, in one embodiment, the chute body is made of template 6, and the templates 6 are reinforced and connected by steel bars 8.

[0025] The frame of the support body 1 is welded from steel bars 8, and the movable wheel 2 is a wooden roller. The end of the support leg of the support body 1 passes through the central shaft hole of the movable wheel 2.

[0026] The connector is a connecting steel wire 7, which passes through the template 6 of the chute body and is tied to the reinforcing bars 8 on the support body 1. Holes are pre-drilled on both sides of the chute template 6, and the connecting steel wire 7 passes through from below the template 6, then wraps upwards and is fastened to the crossbeam of the reinforcing bars 8 on the support body 1. This tying method allows the chute some room for fine adjustment under stress and thermal expansion and contraction.

[0027] The specific working method is as follows: First, the movable support body 1 of the device is pulled manually or mechanically, and the entire chute device is moved to the predetermined pouring position, usually the edge of the wind turbine foundation pit, using the moving wheels 2 at its bottom. The moving wheels 2 are fixed by wedges or other simple methods to prevent the device from sliding during the pouring process;

[0028] A concrete transport truck (such as a mixer truck) dumps concrete at the inlet of the upper section 3 of the chute, located at the highest point of the chute system. At this point, the concrete itself has high gravitational potential energy, and under the action of gravity, the concrete begins to flow automatically downwards along the chute's slope. The concrete flow passes through the upper section 3 and the middle section 4 of the chute. This continuous channel mainly serves to extend the conveying distance, stabilize the flow velocity, and guide the flow uniformly, preventing concrete splashing or segregation.

[0029] When the concrete flows to the lower three-branched chute 5, a concentrated concrete flow is divided into three independent branches. These three discharge ports are respectively aligned with different working faces of the foundation pit. This achieves synchronous diversion from a single delivery source to multiple pouring points, eliminating the need for frequent relocation of pump trucks or concrete mixer trucks, greatly improving pouring efficiency, and ensuring the continuity and integrity of large-volume concrete pouring;

[0030] Once the pouring of a section is completed, the fixing device can be released, allowing the entire equipment to be easily moved to the next work site or the next project site, repeating the process. Its main structure, consisting of wooden formwork 6 and reinforcing steel bars 8, results in low manufacturing costs, relatively light weight, and ease of movement and reuse, effectively reducing construction costs.

[0031] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
