Description

Technical Field

[0001] The utility model relates to the field of concrete pouring equipment, in particular to a concrete pump. Background Art

[0002] A concrete pump, also known as a concrete delivery pump, is a machine that continuously conveys concrete along a pipeline by using pressure. It mainly consists of a pump body and a delivery pipe, and is widely used in construction projects such as building construction, bridges, tunnels, and water conservancy, especially in occasions where a large amount of concrete needs to be conveyed, the operation cycle is long, and the pumping distance and height are large.

[0003] However, the non-wear-resistant characteristics of traditional concrete pumps lead to increased wear of mechanical components, significantly shortening the overall service life, and thus requiring more frequent maintenance and replacement of components. This not only increases the maintenance cost but also affects the continuity of construction. In addition, the insufficient motor power of traditional concrete pumps is a prominent problem, which directly limits their ability to convey concrete and reduces work efficiency. In construction scenarios where rapid and large-scale concrete conveyance is required, insufficient power has become a major bottleneck restricting the project progress. Moreover, the short service life of the piston, as a key component of the concrete pump, is also a drawback that cannot be ignored. The frequent replacement of the piston not only increases the cost but also affects the stability and reliability of the equipment. At the same time, the problem of insufficient lubricating oil supply further exacerbates the wear of the piston and other moving components, shortening the service life of the equipment. Finally, traditional concrete pumps are complex in structure and cumbersome in operation in design, increasing the workload of operators and reducing the overall work efficiency.

Detailed Description of the Preferred Embodiment

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0026] As Figures 1-6 shown, a concrete pump proposed by the present utility model includes a base 7. The base 7 serves as an installation foundation to support the components installed on it. A pumping assembly 1 is provided on one side of the base 7, and the pumping assembly 1 can convey concrete to a preset pouring location. A hydraulic assembly 3 is provided on the side of the base 7 away from the pumping assembly 1, and the hydraulic assembly 3 is used to generate and transmit pressure oil. A lubrication assembly 4 is provided on one side of the hydraulic assembly 3. By providing the lubrication assembly 4, sufficient lubrication is carried out before the equipment is used, extending the service life of the equipment. A motor 2 is provided on the base 7, and the motor 2 is located between the pumping assembly 1 and the hydraulic assembly 3. The motor 2 uses a national standard of 15 kw, with stronger power, providing sufficient power for the overall equipment.

[0027] The pumping assembly 1 includes a concrete cylinder 11. At the top of the concrete cylinder 11, there is a feeding port 12. The setting of the feeding port 12 facilitates the user to pour in concrete. On one side of the concrete cylinder 11, there is a conveying pipeline 13. Inside the concrete cylinder 11, there is a stirring structure and an integral concrete piston. The material of the stirring structure is high-carbon steel, which is more wear-resistant. While extending the service life of the equipment, it can also transport larger concrete particles. The integral concrete piston is made of a wear-resistant and corrosion-resistant model airplane tube material, making the service life of the integral concrete piston longer. On one side of the stirring structure, there is an oil pump 14. The oil pump 14 is located outside the concrete cylinder 11. On the base 7, there is a handle 2 16. The handle 2 16 is connected to the oil pump 14 for control. When the user pushes the handle 2 16, the double-vane pump 31 can supply oil to the oil pump 14 through an oil pipeline to provide power, so that the stirring structure connected to the oil pump 14 rotates to prevent the centrifugation of concrete.

[0028] The hydraulic assembly 3 includes an installation shell 1 37. Inside the installation shell 1 37, there is a main oil cylinder 32. On one side of the base 7, there is a connecting piece 1 35. The connecting piece 1 35 is the installation base for the connecting piece 2 36 and the hydraulic rod 33. The connecting piece 2 36 is movably arranged on the connecting piece 1 35, allowing the connecting piece 2 36 to rotate at a certain angle. At the top of the connecting piece 2 36, there is a hydraulic rod 33. The hydraulic rod 33 is connected to one side of the installation shell 1 37. On the base 7 on one side of the main oil cylinder 32, there is a handle 1 34. The handle 1 34 is connected to the hydraulic rod 33 for control. When the user pushes the handle 1 34, the hydraulic rod 33 can lift one side of the installation shell 1 37 and the main oil cylinder 32, so that one side of the concrete cylinder 11 inclines and descends, making it more convenient for the user to pour in concrete. The main oil cylinder 32 is connected to the integral concrete piston inside the concrete cylinder 11. The main oil cylinder 32 provides pressure oil for the integral concrete piston, driving the piston in the integral concrete piston to make reciprocating movements, thereby realizing the suction and discharge of concrete. On one side of the motor 2 on the base 7, there is a double-vane pump 31. The double-vane pump 31 has more powerful power and can transport a larger amount of pressure oil. The double-vane pump 31 is connected to the main oil cylinder 32. The double-vane pump 31 fully provides hydraulic energy for the main oil cylinder 32, and then the main oil cylinder 32 converts the hydraulic energy into mechanical energy to drive the integral concrete piston to make reciprocating movements. The handle 2 16 is connected to the double-vane pump 31 for control. When the user pushes the handle 2 16 inward, the double-vane pump 31 can supply pressure oil to the oil pump 14 to provide power for the stirring structure.

[0029] The lubrication assembly 4 includes a ball-rotating oil pump 41 arranged on the base 7. The ball-rotating oil pump 41 is located on the side of the main cylinder 32 away from the handle 1 34. The ball-rotating oil pump 41 can achieve a pressure of 1 MPa to provide sufficient lubricating oil. The ball-rotating oil pump 41 is connected to the stirring structure and the integrated concrete piston in the concrete cylinder 11. The ball-rotating oil pump 41 can lubricate the stirring structure and the integrated piston sufficiently, making the subsequent concrete conveying process smoother while protecting the equipment and extending its service life.

[0030] An integrated control center 5 is arranged on the base 7. The integrated control center 5 is located on one side of the main cylinder 32. An aviation plug 6 is arranged on one side of the integrated control center 5. The integrated control center 5 is connected to the motor 2, the ball-rotating oil pump 41, and the double-vane pump 31 for control. By setting the integrated control center 5, the automation degree of the overall equipment is improved, the operation steps are simplified, and the work efficiency is increased.

[0031] Several wheels 71 are arranged at the bottom of the base 7. A handrail 72 is arranged on one side of the base 7. The arrangements of the wheels 71 and the handrail 72 facilitate the user to move the concrete pump.

[0032] During use, the user can pick up the remote control connected to the integrated control center 5 and start the motor 2 to supply power to the overall equipment. At this time, the ball-rotating oil pump 41 in the lubrication assembly 4 starts to convey lubricating oil to lubricate the stirring structure and the integrated concrete piston in the lubricating pump assembly 1. Then, the user can push the handle 1 34 inward, and the hydraulic rod 33 raises one side of the main cylinder 32. At this time, one side of the concrete cylinder 11 tilts downward, making it more convenient for the user to pour concrete. After pouring, the user pushes the handle 2 16 inward, and the double-vane pump 31 conveys pressure oil to the oil pump 1 14 through the oil pipeline, thereby driving the stirring structure to rotate and preventing the concrete in the concrete cylinder 11 from centrifuging.

[0033] Then, the double-vane pump 31 conveys pressure oil to the main cylinder 32, and the main cylinder 32 converts hydraulic energy into mechanical energy, thereby driving the integrated concrete piston to perform reciprocating motion. When one of the concrete pistons in the integrated concrete piston advances, the other concrete piston retreats. The advancing piston pushes the concrete in the concrete cylinder 11 out and enters the conveying pipeline 13 through the distribution valve. The retreating piston generates a self-priming effect in the concrete cylinder 11 to suck the concrete in the concrete cylinder 11. Through the coordinated actions of the main cylinder 32 and the integrated concrete piston, the concrete can be continuously pumped to the pouring site.

[0034] It should be understood that the above specific embodiments of the present utility model are only for illustrative explanation or interpretation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model.
