Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a concrete conveying device. Background Technology

[0002] Concrete is one of the most widely used materials in modern construction engineering. Its core function is as a structural load-bearing carrier and engineering protective material. Concrete placing and conveying devices are key equipment in construction specifically used for concrete transportation, placement, and pouring. Their core function is to accurately and efficiently deliver the mixed concrete to the designated pouring location, replacing traditional manual handling or simple tool pouring methods, and greatly improving construction efficiency and pouring quality.

[0003] Traditional concrete placing boom conveyors are typically fixed in structure, making it inconvenient to change the placing head according to different placing requirements. This limits the placing effect, and the concrete is prone to sticking, solidifying, or segregating during the conveying process, resulting in uneven distribution and affecting the placing effect. Utility Model Content

[0004] In order to overcome the problems of traditional concrete placing conveyor devices, such as the inconvenience of changing the placing head and the tendency for solidification and segregation to occur during the conveying process, which leads to a decrease in the placing effect, this utility model provides a concrete placing conveyor device.

[0005] The technical solution is as follows: A concrete conveying device includes a conveying component for conveying concrete, a conveying component at the end of the conveying component for mixing and spreading the concrete, a control panel for controlling the working status of the conveying component and the conveying component fixedly installed on the side of the conveying component, the conveying component and the conveying component are both fixedly installed on the upper end of the base, and four sets of casters for controlling the movement of the base are fixedly installed around the four corners of the lower end of the base, and brake pads are provided on the side of the casters.

[0006] Furthermore, the fabric assembly includes a mixing tank, a guide pipe, a first connector, a fabric head, a second connector, a sealing ring, a second drive motor, a rotating shaft, a mixing rod, and a foot column. The guide pipe is fixedly installed on the side of the mixing tank near the bottom, and the first connector is fixedly installed at the end of the guide pipe away from the mixing tank.

[0007] Furthermore, a fabric head is provided at the end of the first connector away from the guide tube, and a second connector is fixedly connected at the end of the fabric head near the first connector.

[0008] Furthermore, the fabric head and the guide tube are detachably connected via a first connector and a second connector, which are detachably connected via bolts and nuts evenly distributed around the fabric head.

[0009] Furthermore, a sealing ring is fitted to the end of the first connector near the second connector, and a control valve for controlling the inlet and outlet is provided on the outside of the connection between the feed pipe and the mixing tank.

[0010] Furthermore, a second drive motor is fixedly installed at the lower middle part of the mixing tank. The upper end of the second drive motor is provided with a rotating shaft. The rotating shaft extends through the bottom of the mixing tank into the interior. The surface of the rotating shaft is linearly distributed and evenly surrounded by stirring rods that are matched with the size of the mixing tank. The second drive motor drives the rotating shaft to rotate, thereby driving the stirring rods to rotate synchronously.

[0011] Furthermore, the conveying assembly includes a mounting plate, a conveyor belt, a first drive motor, and a support column. Two sets of mounting plates are arranged opposite each other, and the two sets of mounting plates are rotatably connected by a connecting shaft. The first drive motor is provided at the end of one set of connecting shafts.

[0012] Furthermore, the first drive motor drives the conveyor belt to rotate via the drive connecting shaft, and three sets of support columns are evenly and fixedly installed at the lower ends of both sets of mounting plates.

[0013] The beneficial effects are: by setting the fabric head as a detachable structure, the fabric assembly of this utility model can replace different fabric heads according to different fabric needs, thus making the effect stronger;

[0014] By incorporating a mixing structure into the concrete placement assembly, the concrete that solidifies and segregates during transport can be mixed evenly, thus ensuring the desired placement effect. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Concrete is an artificial stone material formed by mixing cementitious materials (such as cement), aggregates (sand and stone), water and admixtures (such as water-reducing agents and retarders) in a certain proportion, and then mixing, pouring and hardening it.

[0023] The core function of concrete

[0024] 1. Structural load-bearing (core function)

[0025] High compressive strength: Ordinary concrete has a compressive strength of 20-50MPa, while high-strength concrete can reach over 100MPa, making it suitable for load-bearing structures (beams, columns, and floor slabs).

[0026] Durability: Weather resistant and chemical corrosion resistant (requires protective layer design), lifespan can reach 50-100 years.

[0027] 2. Construction adaptability

[0028] Plasticity: Before hardening, it can be cast into any shape (with template), adapting to complex architectural designs (such as curved surfaces and irregular structures).

[0029] Mechanized construction: Suitable for pumping and concrete placing machine paving, with efficiency far exceeding that of brick or steel structures.

[0030] 3. Economic viability and sustainability

[0031] Low cost: Raw materials (sand, gravel, cement) are widely available, and the overall cost is lower than that of steel and wood.

[0032] Environmental potential: Industrial waste (fly ash, slag) can be used to replace part of the cement, reducing carbon emissions.

[0033] Concrete, as the "skeleton" of modern architecture, is an irreplaceable material due to its high strength, plasticity, and economy. By combining it with steel reinforcement, admixtures, and advanced construction techniques (such as concrete conveying devices), its inherent defects can be overcome to meet diverse needs, from residential buildings to super high-rise buildings, and from roads to nuclear power plants.

[0034] Concrete placing and conveying devices are key equipment in construction engineering, mainly used for efficient and precise conveying and pouring of concrete, solving the problems of low efficiency and poor uniformity in traditional manual pouring.

[0035] Core functions and application scenarios

[0036] core role

[0037] Concrete delivery: Quickly and continuously transporting concrete from the batching plant or pump truck to the construction area.

[0038] Precise concrete placement: According to construction requirements, the concrete is evenly spread on the formwork, steel mesh or working surface to avoid segregation or accumulation.

[0039] Adaptability to different working conditions: With adjustable material distribution heads (such as direct spraying, spraying, etc.), it can adapt to the pouring requirements of different structures (floor slabs, walls, beams and columns, etc.).

[0040] Typical application scenarios

[0041] High-rise building floor slabs: large-area rapid fabric application reduces cold seams.

[0042] Bridge piers: Precisely cast areas with dense steel reinforcement.

[0043] Tunnel lining: Shot concrete is evenly applied to the curved surface.

[0044] Precast component factory: standardized casting molds.

[0045] like Figure 1 As shown, a concrete conveying device includes a conveying component 1 for conveying concrete, a spreading component 2 for mixing and spreading concrete at the end of the conveying component 1, a control panel 5 for controlling the working status of the conveying component 1 and the spreading component 2 fixedly installed on the side of the conveying component 1, the conveying component 1 and the spreading component 2 are both fixedly installed on the upper end of the base 3, and four sets of casters 4 for controlling the movement of the base 3 are fixedly installed around the four corners of the lower end of the base 3, and brake pads are provided on the side of the casters 4.

[0046] Please see Figure 2 - Figure 4In this embodiment, the fabric assembly 2 includes a mixing tank 201, a guide pipe 202, a first connector 203, a fabric head 204, a second connector 205, a sealing ring 206, a second drive motor 207, a rotating shaft 208, a stirring rod 209, and a foot post 210. The guide pipe 202 is fixedly installed on the side of the mixing tank 201 near the bottom. The first connector 203 is fixedly installed at the end of the guide pipe 202 away from the mixing tank 201. The fabric head 204 is located at the end of the first connector 203 away from the guide pipe 202. The second connector 205 is fixedly connected to the end of the fabric head 204 near the first connector 203. The fabric head 204 and the guide pipe 202 are detachably connected via the first connector 203 and the second connector 205. The first connector 203 and the second connector 205 are detachably connected via bolts and nuts evenly distributed around the fabric head. By setting the first connector 203 and the second connector 205 into a detachable connection structure, it is convenient to... Different fabric heads 204 with different structures are replaced according to different fabric requirements. A sealing ring 206 is attached to one end of the first connector 203 near the second connector 205. The sealing ring 206 can prevent slurry leakage. A control valve for controlling the inlet and outlet is provided on the outside of the connection between the guide pipe 202 and the mixing tank 201. A second drive motor 207 is fixedly installed in the middle of the lower end of the mixing tank 201. A rotating shaft 208 is provided at the upper end of the second drive motor 207. The rotating shaft 208 extends through the bottom of the mixing tank 201 and into the interior. A stirring rod 209 with the same size as the mixing tank 201 is fixedly installed around the surface of the rotating shaft 208 in a linear distribution. The second drive motor 207 drives the rotating shaft 208 to rotate and drive the stirring rod 209 to rotate synchronously. By setting multiple stirring rods 209 in the mixing tank 201, the pumped segregated concrete is rotated and stirred before fabrication, which can re-homogenize the aggregate and slurry and prevent solidification or segregation, which would reduce the fabrication effect.

[0047] Please see Figure 5 In this embodiment, the conveying assembly 1 includes a mounting plate 101, a conveyor belt 102, a first drive motor 103, and support columns 104. Two sets of mounting plates 101 are arranged opposite each other, and the two sets of mounting plates 101 are rotatably connected to the conveyor belt 102 through a connecting shaft. The end of one set of connecting shafts is provided with a first drive motor 103, which drives the conveyor belt 102 to rotate through the driving connecting shaft. Three sets of support columns 104 are evenly and fixedly installed at the lower ends of both sets of mounting plates 101.

[0048] When working, first push the device to move it to the corresponding position, and install the fabric head 204 according to actual needs. Then, use bolts and nuts to install and fix the second connector 205 on the first connector 203.

[0049] Afterwards, the parameters of the conveying component 1 and the placing component 2 are set using the control panel 5, and then the concrete is pre-conveyed and buffered. The concrete is poured into the conveyor belt 102 by the external pumping system.

[0050] Then, the concrete is conveyed through the conveyor assembly 1. The first drive motor 103 (Siemens 1LE0003, 7.5kW) drives the conveyor belt 102 to run at a certain speed, and the concrete is fed into the mixing tank 201 at a uniform speed.

[0051] Next, dynamic mixing and homogenization are carried out. The second drive motor 207 (NORD BA3550, 11kW) drives the rotating shaft 208 (42CrMo quenched and tempered steel) to rotate at a certain speed, which in turn drives the mixing rod 209 to rotate synchronously. The linearly distributed mixing rod 209 continuously mixes the concrete by rotating, breaks up the segregated aggregate lumps, and mixes the concrete that has solidified and segregated evenly.

[0052] The mixing time is preset by the control panel. After mixing is completed, the control valve (VTON, DN150 pneumatic butterfly valve) on the outside of the feed pipe 202 is opened, so that the homogeneous concrete flows into the currently assembled placing head 204 through the feed pipe 202. The concrete is then distributed through the placing head 204 and discharged to the required location.

[0053] In actual use, the fabric head 204 can be replaced according to different fabric requirements to meet different fabric needs.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
