Description

Technical Field

[0001] This utility model relates to the field of material feeding structure technology, specifically to a conveyor belt for vertically lifting concrete. Background Technology

[0002] Concrete is an extremely common material in building construction, often used to pour concrete for various structures. Before pouring, concrete needs to be transported from its storage location to the pouring location, or from a lower location to a higher location.

[0003] Concrete gradation: The higher the concrete gradation, the larger the diameter of the aggregate particles in the concrete components, and the lower the cost of concrete with the same strength. Concrete slump: The higher the slump, the stronger the fluidity of the concrete; the lower the slump, the worse the fluidity of the concrete.

[0004] In the pouring of large-scale construction projects, such as the filling of dams, high-grade concrete with high slump is required. However, the existing gantry-type concrete placing booms used in dam construction lack sufficient horizontal space, necessitating the use of vertically lifting equipment. Since high-grade concrete cannot pass through pump pipes, pumped concrete pouring equipment is not suitable for concrete containing large-diameter aggregates.

[0005] Existing commonly used auger lifting devices, while capable of direct vertical lifting, rely on the rotation of spiral blades to forcibly compress and lift concrete. However, in large-scale construction projects using high-grade concrete, the larger aggregate particle diameters result in greater pressure from the spiral blades during lifting, shortening the auger's lifespan. Furthermore, the unsealed transport environment of the auger necessitates friction to reduce concrete flowability; high-slump concrete is more fluid, further reducing the lifting efficiency of the auger lifting device. Utility Model Content

[0006] The purpose of this invention is to provide a vertically lifting concrete conveyor belt to solve the problem of low vertical lifting material feeding efficiency in construction environments that require concrete with high gradation and high slump.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A vertical concrete lifting conveyor belt includes a main conveyor belt and an auxiliary conveyor belt. Multiple first partitions are evenly spaced on the main conveyor belt, and multiple second partitions are evenly spaced on the auxiliary conveyor belt. The spacing between the first partitions is the same as the spacing between the second partitions. The main conveyor belt includes a first upper horizontal section, a first vertical section, and a first lower horizontal section, forming a Z-shaped conveyor belt. The auxiliary conveyor belt includes a second vertical section and a second lower horizontal section, forming an L-shaped conveyor belt. The second vertical section and the second lower horizontal section are positioned within the included angle space of the first vertical section and the first lower horizontal section, with the first and second vertical sections and the first and second lower horizontal sections arranged parallel to each other. The alignment of the first partitions at the positions of the first and second vertical sections forms a partitioned transport space.

[0009] Furthermore, Z-shaped first outer shell plates are installed on both sides of the main conveyor belt, and L-shaped second outer shell plates are installed on both sides of the auxiliary conveyor belt.

[0010] Furthermore, the Z-shaped first outer shell panel and the L-shaped second outer shell panel abut against each other, so that the partitioned transport space forms a relatively enclosed transport space.

[0011] Furthermore, it also includes a first chain and a second chain; the first chain is disposed on the first partition, passes through the middle of the outer ends of multiple first partitions, circles around the main conveyor belt in the transport direction, and is fixedly connected at the position where it passes through the first partition, so that the first partitions are connected to each other; the second chain is disposed on the first partition, passes through the middle of the outer ends of multiple second partitions, circles around the auxiliary conveyor belt in the transport direction, and is fixedly connected at the position where it passes through the second partition, so that the second partitions are connected to each other.

[0012] Furthermore, the main conveyor belt also includes a first inner roller and a first outer roller, the first inner roller being installed at the inner corner of the main conveyor belt and the first outer roller being installed at the outer corner of the main conveyor belt; the auxiliary conveyor belt also includes a second inner roller and a second outer roller, the second inner roller being installed at the inner corner of the auxiliary conveyor belt and the second outer roller being installed at the outer corner of the auxiliary conveyor belt; the first outer roller and the second outer roller are both a pair of short rollers that are broken in the middle, which is used to leave space in the middle to facilitate the passage of the first partition or the second partition.

[0013] Furthermore, the main conveyor belt also includes a first motor, which is coaxially connected to one of the first inner rollers in the main conveyor belt; the auxiliary conveyor belt also includes a second motor, which is coaxially connected to one of the second inner rollers in the auxiliary conveyor belt.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] The second vertical section, the first partition, the second partition, and the first vertical section form a partitioned transport space for direct lifting of concrete. In this invention, the first and second partitions are aligned to form a bearing surface, and the vertical lifting is completed by the operation of the conveyor belt. This results in higher lifting efficiency and is more suitable for lifting concrete with high slump. Furthermore, since this invention uses direct transport, it causes less damage to the main and auxiliary conveyor belts when transporting concrete with high gradation. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0022] like Figure 1 , Figure 2As shown, a vertical concrete lifting conveyor belt includes a main conveyor belt 1 and an auxiliary conveyor belt 2. The main conveyor belt 1 is provided with a plurality of first partitions 14 at equal intervals, and the auxiliary conveyor belt 2 is provided with a plurality of second partitions 23 at equal intervals. The spacing between the first partitions 14 is the same as the spacing between the second partitions 23. The main conveyor belt 1 includes a first upper horizontal section 11, a first vertical section 12 and a first lower horizontal section 13. The first upper horizontal section 11, the first vertical section 12 and the first lower horizontal section 13 of the main conveyor belt 1 form a Z-shaped conveyor belt. The auxiliary transport belt 2 includes a second vertical section 21 and a second lower horizontal section 22, which form an L-shaped transport belt. The second vertical section 21 and the second lower horizontal section 22 are arranged in the space between the first vertical section 12 and the first lower horizontal section 13. The first vertical section 12 and the second vertical section 21 are arranged parallel to each other, and the first lower horizontal section 13 and the second lower horizontal section 22 are arranged parallel to each other. The alignment of the first partition 14 at the position of the first vertical section 12 and the second partition 23 at the position of the second vertical section 21 forms a partitioned transport space.

[0023] During the conveying process, the first lower horizontal section 13 of the main conveyor belt 1 is used for concrete loading. After being lifted by the first vertical section 12, the concrete is transported to the first upper horizontal section 11, where it undergoes further processing. Alternatively, the concrete can be directly poured using a pouring pipe at the outlet of the first upper horizontal section 11, or other transfer methods can be used to complete the concrete placement. The main difficulty in the vertical lifting of concrete by the Z-shaped main conveyor belt 1 lies in the fact that the concrete carried at the first vertical section 12 is prone to slippage. This invention utilizes an auxiliary conveyor belt 2 to assist the lifting of the main conveyor belt 1. The auxiliary conveyor belt 2 is positioned within the angled space between the first vertical section 12 and the first lower horizontal section 13 of the main conveyor belt 1, ensuring that the first vertical section 12 and the second vertical section 21 are parallel. Furthermore, the first partition 14 at the position of the first vertical section 12 and the second partition 23 at the position of the second vertical section 21 are aligned, guaranteeing that the main conveyor belt 1 and the auxiliary conveyor belt 2 operate at the same speed. This ensures that when the concrete is transported to the position of the first vertical section 12, the second vertical section 21, the first partition 14, the second partition 23, and the first vertical section 12 form a partitioned transport space, allowing for direct lifting of the concrete. The lifting method of this invention involves the alignment of the first partition 14 and the second partition 23 to form a bearing surface, utilizing the operation of the conveyor belt to complete the vertical lifting, resulting in higher lifting efficiency. Moreover, this invention's transport method is direct transport, minimizing damage to the main conveyor belt 1 and the auxiliary conveyor belt 2.

[0024] It should be noted that in the pre-setting of the main conveyor belt 1 and the auxiliary conveyor belt 2, it is ensured that the gap between the first partition 14 and the gap between the second partition 23 are the same, and that the first partition 14 corresponds to the second partition 23 to complete the transport on the vertical section of the main conveyor belt 1. However, in actual operation, there are errors, and the first partition 14 and the second partition 23 cannot be guaranteed to be absolutely aligned. However, because the concrete used in the dam has a high gradation and contains aggregate particles with a large diameter, it is not easy for it to flow out from the gap between the first partition 14 and the second partition 23. A small amount of outflow will not affect the overall transport and can still ensure that most of the concrete is lifted. Therefore, the error in actual transport has little impact on the vertical transport of the main conveyor belt 1 in conjunction with the auxiliary conveyor belt 2.

[0025] Secondly, the main conveyor belt 1 and the auxiliary conveyor belt 2 mentioned in this utility model are both metal chain plate belts, also called chain plate conveyor belts. Chain plate conveyor belts are a type of conveyor belt composed of single plates. They have high strength and strong support. The first partition 14 or the second partition 23 is installed on the chain plate conveyor belt by welding, which can form a strong support force and ensure the effective lifting of concrete.

[0026] Furthermore, Z-shaped first outer shell plates are installed on both sides of the main conveyor belt 1, and L-shaped second outer shell plates are installed on both sides of the auxiliary conveyor belt 2. The first and second outer shell plates mainly shield the sides of the main conveyor belt 1 and the auxiliary conveyor belt 2.

[0027] Furthermore, the Z-shaped first outer shell panel and the L-shaped second outer shell panel abut against each other, forming a relatively enclosed transport space. The first vertical segment 12, the second vertical segment 21, the first partition 14, and the second partition 23 form the enclosed transport space, but holes are left on both sides to ensure that the first outer shell panel and the second outer shell panel abut against each other. That is, the length of the first outer shell panel and the second outer shell panel extending to the edge is the same as that of the first partition 14 and the second partition 23. The first outer shell panel and the second outer shell panel are completely closed, forming a relatively enclosed transport space.

[0028] like Figure 3 , Figure 4As shown, further, it also includes a first chain and a second chain; the first chain is disposed on the first partition 14, passes through the middle of the outer ends of the plurality of first partitions 14, wraps around once along the transport direction of the main conveyor belt 1, and is fixedly connected at the position where it passes through the first partition 14, so that the first partition 14 is connected to the first partition 14; the second chain is disposed on the first partition 14, passes through the middle of the outer ends of the plurality of second partitions 23, wraps around once along the transport direction of the auxiliary conveyor belt 2, and is fixedly connected at the position where it passes through the second partition 23, so that the second partition 23 is connected to the second partition 23. The chain is installed to increase the load-bearing capacity of the first partition 14 and the second partition 23. Originally, the first partition 14 of the first vertical section 12 and the second partition 23 of the second vertical section 21 each bore the weight of the concrete individually. After adding the chain, the first partition 14 of the first upper horizontal section 11 is connected to the first partition 14 of the first vertical section 12 through the chain, and they jointly bear the weight of the concrete. As a result, the natural wear and tear during the operation of the main conveyor belt 1 and the auxiliary conveyor belt 2 will be reduced. Note: The length of the chain is fixed, but the distance between the outer ends of the first partitions 14 changes. Therefore, the chain is set so that the length between the first partitions 14 is slightly larger than the distance when the first partitions 14 are parallel. In actual operation, the first partitions 14 at the corners will pull on the adjacent first partitions 14, causing the adjacent first partitions 14 to tilt slightly to adapt to the gap between the first partitions 14.

[0029] Furthermore, the main conveyor belt 1 also includes a first inner roller 17 and a first outer roller 18. The first inner roller 17 is installed at the inner corner of the main conveyor belt 1, and the first outer roller 18 is installed at the outer corner of the main conveyor belt 1. The auxiliary conveyor belt 2 also includes a second inner roller 26 and a second outer roller 27. The second inner roller 26 is installed at the inner corner of the auxiliary conveyor belt 2, and the second outer roller 27 is installed at the outer corner of the auxiliary conveyor belt 2. Both the first outer roller 18 and the second outer roller 27 are a pair of short rollers that are broken in the middle, which leaves space in the middle to facilitate the passage of the first partition 14 or the second partition 23. The function of the first outer roller 18 and the second outer roller 27 is to be set at the outer corner to help the main conveyor belt 1 or the auxiliary conveyor belt 2 turn. The first outer roller 18 and the second outer roller 27 are a pair of short rollers that are broken in the middle, which leaves space in the middle to facilitate the passage of the first partition 14 or the second partition 23.

[0030] The main conveyor belt 1 further includes a first motor, which is coaxially connected to one of the first inner rollers 17 within the main conveyor belt 1; the auxiliary conveyor belt 2 further includes a second motor, which is coaxially connected to one of the second inner rollers 26 within the auxiliary conveyor belt 2. The main conveyor belt 1 is driven by the first motor, and the auxiliary conveyor belt 2 is driven by the second motor.
