Description

Technical Field

[0001] This invention relates to the field of concrete pumping equipment technology, and in particular to a multifunctional underwater concrete pumping equipment for underwater engineering. Background Technology

[0002] In the field of underwater engineering construction, the rapid development of large-scale infrastructure such as cross-sea bridges, subsea tunnels, and port terminals has placed higher demands on underwater concrete pumping technology. However, traditional concrete pumping equipment has many shortcomings in practical applications, making it difficult to meet the needs of diverse underwater construction scenarios. For example, traditional equipment often lacks an effective large particle barrier mechanism, allowing larger gravel and sand particles in the concrete to easily enter the pipeline, causing blockages in the discharge pipe and short pipes, thus interrupting the pumping process and affecting the continuity of construction. In addition, the filtration structure of traditional equipment is mostly a fixed design, which cannot be flexibly adjusted according to the different characteristics of concrete. It can only be adapted to different types of concrete through additional pretreatment processes, which not only increases the complexity of construction but also significantly reduces construction efficiency, limiting the application range of the equipment in various underwater projects.

[0003] Meanwhile, traditional pumping equipment uses a relatively simple mixing method, making it difficult to fully mix the various components of concrete. This easily leads to segregation, resulting in substandard concrete strength and severely impacting the safety and service life of underwater structures. In some complex subsea foundation construction projects, the equipment often sways due to its inability to adapt to uneven seabed surfaces, causing uneven concrete pumping and resulting in localized over- or under-pours, wasting materials and affecting project quality. Therefore, developing a multifunctional underwater concrete pumping device that can solve the above problems has become an urgent technical challenge in current underwater engineering construction.

[0004] This invention addresses the shortcomings of existing technologies by proposing a multifunctional underwater concrete pumping device for underwater engineering. The device aims to achieve effective filtration, uniform mixing, and stable pumping of concrete through innovative design, while improving the versatility and construction flexibility of the equipment, ensuring the high efficiency and reliability of underwater concrete construction. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional underwater concrete pumping device for underwater engineering.

[0006] To achieve the above objectives, the present invention is implemented according to the following technical solution:

[0007] This invention addresses the problems of existing underwater concrete pumping equipment, such as easy clogging, inflexible filtration, uneven mixing, and insufficient equipment stability. It proposes a multi-functional underwater concrete pumping device for underwater engineering. Through innovative structural design, the aforementioned technical problems are solved, significantly improving the continuity, stability, and construction efficiency of underwater concrete pumping.

[0008] This invention provides a multifunctional underwater concrete pumping device for underwater engineering, comprising a pumping vehicle, a housing, a feed hopper, partitions, a snap-fit ​​assembly, a mixing assembly, short pipes, a pump body, a discharge pipe, cylinders, and support plates. The pumping vehicle serves as the basic support platform for the equipment. The housing is fixedly mounted on its top, and two sets of long plates are fixedly mounted on the bottom of the pumping vehicle. Cylinders are fixedly mounted at both ends of the top of each set of long plates, and the output ends of the four sets of cylinders are connected to the support plates. The height of the support plates is adjusted by driving the cylinders to adapt to different ground flatness levels, ensuring the stability of the pumping vehicle during construction.

[0009] Furthermore, the container is the core component for concrete storage and processing. A feed hopper is fixedly installed on its top for adding concrete into the container. A partition is slidably installed inside the container, effectively blocking larger stone and sand particles to prevent them from entering the subsequent piping system and avoiding blockages in the short pipes and discharge pipes. Specifically, both sides of the container have placement slots and sliding grooves, with locking assemblies installed inside the placement slots and sliding grooves on the same side. The locking assembly includes a sliding plate, an insert plate, a connecting plate, a frame, a slider, a fixing plate, a pull plate, a locking plate, a spring one, and a spring two. The sliding plate has an insert plate and a connecting plate fixedly installed at both ends, with the insert plate movably inserted into the partition to secure it. A frame is fixedly installed at the bottom of the connecting plate, with a slider slidably installed inside the frame. A fixing plate is fixedly installed on one side of the slider, a pull plate is fixedly installed on one side of the fixing plate, and a locking plate is fixedly installed on one side of the pull plate. The locking plate movably inserts into the container to lock the locking assembly. A spring is installed inside the placement groove, with its two ends fixedly connected to the slide plate and one inner wall of the placement groove, respectively. A spring is installed inside the frame, with its two ends fixedly connected to the slider and one inner wall of the frame, respectively. By pulling the pull plate, the insert plate can be detached from the partition, making it easy to replace partitions of different specifications to meet the filtration needs of different concretes.

[0010] Furthermore, the mixing assembly is housed inside the casing and includes bevel gear one, bevel gear two, bevel gear three, mixing shaft one, mixing shaft two, collars, mixing rods, a rotating shaft, and a motor. Bevel gear two and bevel gear three mesh with bevel gear one, forming a bidirectional transmission structure. Mixing shaft two is fixedly mounted at one end of bevel gear three, and mixing shaft one is fixedly mounted inside bevel gear two. Mixing shaft one rotates through the interior of mixing shaft two. Multiple sets of collars are fixedly mounted on the outer sides of both mixing shaft one and mixing shaft two, and multiple sets of mixing rods are fixedly mounted on the outer sides of the collars. A rotating shaft is fixedly mounted on one side of bevel gear one, rotating through the casing to one side. A motor is fixedly mounted on one side of the casing, and the motor's output shaft is fixedly connected to the rotating shaft. By driving the motor, bevel gear one rotates, causing bevel gear two and bevel gear three to rotate in opposite directions, which in turn drives mixing shaft one and mixing shaft two to rotate in opposite directions, achieving a bidirectional mixing function. This ensures that the concrete remains uniform before pumping and avoids segregation.

[0011] Furthermore, the short pipe is fixedly installed at the bottom of the tank, extending into the interior of the tank. A pump body is fixedly installed at the bottom of the short pipe, and a discharge pipe is fixedly installed at the bottom of the pump body, extending to one side of the pump truck. Pressure is generated by the pump body to transport concrete through the discharge pipe to the required underwater construction location.

[0012] The working principle of this invention is as follows:

[0013] S1. Concrete enters the housing through the feed hopper. Baffles effectively block larger gravel and sand particles, preventing them from entering the short pipe and discharge pipe, thus avoiding blockages. When a baffle needs replacement, pull the pull plate to detach the insert plate from the baffle, facilitating quick replacement of baffles of different specifications. After replacement, the insert plate is re-inserted into the baffle by the reset action of springs one and two, completing the fixation.

[0014] S2. Start the motor, which drives bevel gear one to rotate, while bevel gear two and bevel gear three rotate in opposite directions. This, in turn, drives mixing shaft one and mixing shaft two to rotate in opposite directions, achieving bidirectional mixing. The mixing rod thoroughly mixes the concrete, ensuring that the concrete remains uniform before pumping and preventing segregation.

[0015] S3. Start the pump and transport the concrete to the underwater construction location through the short pipe and discharge pipe. Adjust the height of the support plate by driving the cylinder to ensure that the pump truck remains stable during construction and avoids affecting the pumping effect due to equipment shaking.

[0016] The beneficial effects of this invention are:

[0017] First, by setting up baffles and snap-fit ​​components, larger stone and sand particles are effectively blocked, preventing blockage of short pipes and discharge pipes, ensuring that concrete can be pumped continuously and stably, and guaranteeing the continuity of underwater engineering construction.

[0018] Secondly, the design of the snap-fit ​​components enables the rapid installation and disassembly of the baffles, facilitating the replacement of baffles of different specifications, thereby adapting to the filtration needs of different concretes and greatly improving the versatility of the equipment and the flexibility of construction.

[0019] Third, the bidirectional mixing function of the mixing components ensures that the concrete remains uniform before pumping, effectively preventing segregation and ensuring the strength and stability of the underwater concrete structure, thus improving project quality. Fourth, the adjustable cylinders and support plates allow the equipment to adapt to different ground flatness levels, maintaining stability during the pumping process and preventing equipment vibration from affecting the pumping effect.

[0020] In summary, the multifunctional underwater concrete pumping equipment for underwater engineering provided by this invention solves the problems of easy clogging, inflexible filtration, uneven mixing, and insufficient equipment stability of traditional equipment in underwater construction through innovative structural design. It has significant advantages in preventing clogging, improving versatility, avoiding segregation, and enhancing stability. It is suitable for a variety of underwater construction scenarios and has broad application prospects. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0027] This invention provides a multi-functional underwater concrete pumping device for underwater engineering, the structure and operating principle of which are combined with the attached... Figure 1 To be continued Figure 4 A detailed description is provided below. The equipment mainly consists of a pump truck 1, a housing 4, a feed hopper 2, a partition 3, a snap-fit ​​assembly 5, a mixing assembly 6, a short pipe 7, a pump body 8, a discharge pipe 9, a cylinder 10, and a support plate 11. Each component achieves efficient and stable underwater concrete pumping through specific connection methods and functional designs.

[0028] like Figure 1-4As shown, the pump truck 1 is the basic support platform for the entire equipment, with a box 4 fixedly installed on its top. The box 4 is used for storing and processing concrete. A feed hopper 2 is located on the top of the box 4, providing a convenient inlet for concrete delivery. A partition 3 is slidably installed inside the box 4. The function of the partition 3 is to effectively block larger stone and sand particles, preventing them from entering the subsequent piping system and thus avoiding blockages in the short pipe 7 and the discharge pipe 9. To enable quick replacement of the partition 3, placement slots and chutes are provided on both sides of the box 4. A snap-fit ​​assembly 5 is installed inside the placement slot and chutes on the same side. The snap-fit ​​assembly 5 includes a sliding plate 502, an insert plate 501, a connecting plate 503, a frame 505, a slider 506, a fixing plate 507, a pull plate 508, a locking plate 509, a first spring 504, and a second spring 510. The slide plate 502 has an insert plate 501 and a connecting plate 503 fixedly installed at both ends. The insert plate 501 is movably inserted into the partition 3 to fix the partition 3. The bottom of the connecting plate 503 has a frame 505 fixedly installed. The slider 506 is slidably installed inside the frame 505. The fixing plate 507 is fixedly installed on one side of the slider 506. The pull plate 508 is fixedly installed on one side of the fixing plate 507. The locking plate 509 is fixedly installed on one side of the pull plate 508. The locking plate 509 is movably inserted into the box 4 to lock the buckle assembly 5. A spring 504 is installed inside the placement slot. The two ends of the spring 504 are fixedly connected to the inner wall of one side of the slide plate 502 and the placement slot, respectively. A spring 510 is installed inside the frame 505. The two ends of the spring 510 are fixedly connected to the slider 506 and the inner wall of one side of the frame 505, respectively. When it is necessary to replace the partition 3, the operator pulls the pull plate 508, causing the fixing plate 507 to move the slider 506 and stretch the second spring 510. Simultaneously, pulling the pull plate 508 downwards causes the frame 505 to move the connecting plate 503 downwards, and the sliding plate 502 causes the insert plate 501 to disengage from the partition 3, completing the disassembly of the partition 3. After replacement, releasing the pull plate 508 allows the springs 504 and 5010 to reset, causing the insert plate 501 to re-insert into the partition 3, thus securing the partition 3. This design significantly improves the replacement efficiency of the partition 3 and provides flexibility to meet the filtration needs of different concrete specifications.

[0029] The housing 4 also houses a stirring assembly 6, which includes a first bevel gear 601, a second bevel gear 602, a third bevel gear 603, a first stirring shaft 604, a second stirring shaft 605, a collar 606, a stirring rod 607, a rotating shaft 608, and a motor 609. Figure 3As shown, bevel gears 2 (602) and 3 (603) mesh with bevel gear 1 (601), forming a bidirectional transmission structure. A stirring shaft 2 (605) is fixedly mounted at one end of bevel gear 3 (603). A stirring shaft 1 (604) is fixedly mounted inside bevel gear 2 (602), and the stirring shaft 1 (604) rotatably penetrates into the interior of stirring shaft 2 (605). Multiple sets of collars 606 are fixedly mounted on the outer sides of both stirring shafts 1 (604) and 2 (605), and multiple sets of stirring rods 607 are fixedly mounted on the outer sides of the collars 606. A rotating shaft 608 is fixedly mounted on one side of bevel gear 1 (601), and the rotating shaft 608 rotatably penetrates into one side of housing 12. A motor 609 is fixedly mounted on one side of housing 12, and the output shaft of motor 609 is fixedly connected to the rotating shaft 608. After starting motor 609, motor 609 drives bevel gear one 601 to rotate, while bevel gear two 602 and bevel gear three 603 rotate in opposite directions. This, in turn, drives mixing shaft one 604 and mixing shaft two 605 to rotate in opposite directions. Mixing rod 607 thoroughly mixes the concrete, ensuring that the concrete remains uniform before pumping and preventing segregation. The design of mixing component 6 not only improves the mixing effect of concrete but also solves the problem of uneven mixing in traditional equipment through bidirectional mixing.

[0030] A short pipe 7 is fixedly installed at the bottom of the housing 4, extending into the interior of the housing 4. A pump body 8 is fixedly installed at the bottom of the short pipe 7, and a discharge pipe 9 is fixedly installed at the bottom of the pump body 8, extending to one side of the pump truck 1. Pressure generated by the pump body 8 transports concrete through the short pipe 7 and the discharge pipe 9 to the underwater construction location. Two sets of long plates are fixedly installed at the bottom of the pump truck 1. Cylinders 10 are fixedly installed at both ends of the top of each set of long plates. The output ends of the four sets of cylinders 10 are connected to support plates 11. During construction, the height of the support plates 11 is adjusted by driving the cylinders 10 to adapt to different ground flatness levels, ensuring the stability of the pump truck 1 during construction. The design of the cylinders 10 and support plates 11 solves the problem of shaking caused by uneven ground in traditional equipment, further enhancing the stability of the pumping process.

[0031] The equipment's workflow is as follows:

[0032] S1. Concrete enters the housing 4 through the feed hopper 2. The baffle 3 effectively blocks larger stone and sand particles, preventing them from entering the short pipe 7 and the discharge pipe 9, thus avoiding pipe blockage. When the baffle 3 needs to be replaced, pull the pull plate 508 to disengage the insert plate 501 from inside the baffle 3, facilitating quick replacement of baffles 3 of different specifications. After replacement, the insert plate 501 is re-inserted into the baffle 3 by the reset action of spring 504 and spring 510, completing the fixation.

[0033] S2. Start motor 609, which drives bevel gear 1 601 to rotate, bevel gear 2 602 and bevel gear 3 603 to rotate in opposite directions, thereby driving mixing shaft 1 604 and mixing shaft 2 605 to rotate in opposite directions. Mixing rod 607 fully mixes the concrete to ensure that the concrete remains uniform before pumping and to avoid segregation.

[0034] S3. Start the pump body 8, and transport the concrete to the underwater construction location through the short pipe 7 and the discharge pipe 9. Adjust the height of the support plate 11 by driving the cylinder 10 to ensure that the pump truck 1 remains stable during construction and avoids affecting the pumping effect due to equipment shaking.

[0035] In practical applications, such as undersea tunnel construction or cross-sea bridge foundation building, this equipment plays a crucial role. Taking undersea tunnel construction as an example, the construction site is usually located in deep water, with a complex environment and extremely high requirements for the continuity and stability of concrete pumping. By using the equipment of this invention, firstly, the baffle 3 effectively filters larger particles in the concrete, preventing pipe blockage and ensuring that the concrete can be continuously and stably pumped to the construction location. Secondly, through the bidirectional mixing function of the mixing component 6, the concrete remains in a uniform state before pumping, avoiding segregation and ensuring the strength and stability of the underwater concrete structure. Finally, through the adjustment function of the cylinder 10 and the support plate 11, the equipment can adapt to complex seabed terrain, maintain the stability of the pumping process, and avoid the impact of equipment shaking on the pumping effect. The entire construction process is highly efficient and smooth, significantly improving construction efficiency and project quality.

[0036] In summary, this invention, through its innovative structural design, solves the problems of easy clogging, inflexible filtration, uneven mixing, and insufficient stability in traditional underwater concrete pumping equipment. The design of the baffle plate 3 and the snap-fit ​​assembly 5 effectively blocks larger gravel and sand particles, preventing pipe blockage and ensuring continuous concrete pumping. The quick installation and disassembly function of the snap-fit ​​assembly 5 significantly improves the equipment's versatility and construction flexibility. The bidirectional mixing function of the mixing assembly 6 ensures that the concrete remains uniform before pumping, avoiding segregation. The adjustment function of the cylinder 10 and the support plate 11 enhances the equipment's stability, adapts to different ground flatness levels, and ensures the smoothness of the pumping process. This invention is applicable to various underwater construction scenarios and has broad application prospects.

[0037] The technical solutions of the present invention are not limited to the specific embodiments described above. Any technical modifications made in accordance with the technical solutions of the present invention fall within the protection scope of the present invention.
