Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically to a deep concrete pouring device for water conservancy engineering construction. Background Technology

[0002] Concrete pouring is a core construction process in water conservancy projects to form dams, foundations, and other structures. Its conveying efficiency and pipeline durability directly affect the quality of the project. Therefore, it is necessary to optimize the pouring device to address issues such as airflow interference and pipeline impact in deep pouring.

[0003] Patent specification CN222294988U discloses a concrete pouring mechanism for water conservancy engineering construction, including a support base, a pump body disposed on the inner surface of the support base, a pouring pipe disposed at the upper end of the pump body, a feed cylinder slidably disposed on the inner surface of the support base, a feed inlet disposed at the bottom of the feed cylinder, a receiving inlet disposed on the surface of the pump body, and the outer surface of the feed cylinder inserted into the inner surface of the receiving inlet. This invention utilizes an inclined feed cylinder structure with built-in threaded conveying blades to deliver concrete. When used in conjunction with a vibration component, the feed speed can be adjusted during feeding, and the vibration ensures rapid concrete descent without clogging or sticking.

[0004] However, the above-mentioned technical solutions have obvious limitations in practical applications: although they can adjust the feeding speed during feeding and the vibration can make the concrete fall quickly without clogging or sticking, the excessively fast falling speed of the concrete will generate rising gas at the outlet of the conveying pipe. This airflow will then flow in the opposite direction, hindering the conveying speed. Furthermore, with multiple sections of the conveying pipe connected, the concrete flow velocity will slow down and the pressure will increase at bends, causing impact on the inner wall of the bend pipe, affecting the conveying effect and the pipe's lifespan. Therefore, we propose a deep concrete pouring device for hydraulic engineering construction. Utility Model Content

[0005] This utility model provides a deep concrete pouring device for water conservancy engineering construction, which solves the problems mentioned in the background art, such as the excessively fast falling speed of concrete material generating rising gas at the outlet of the conveying pipe, which in turn causes the airflow to flow in the opposite direction, hindering the conveying speed, and the concrete flow rate slowing down and pressure increasing at bends in multiple connected conveying pipes, causing impact on the inner wall of the bend pipe, affecting the conveying effect and pipe life.

[0006] To solve the above-mentioned technical problems, an embodiment of this utility model provides a deep concrete pouring device for water conservancy engineering construction, including a conveyor arm one, a transition cylinder rotatably connected to one end of the conveyor arm one, a pin block fixedly connected to the outer surface of the transition cylinder, a conveyor arm two rotatably mounted on the transition cylinder through the pin block, a connecting pipe inserted through the middle of the transition cylinder, a sealing block fixedly connected to one side wall of the conveyor arm two, an installation sleeve plate fixedly connected to one side wall of the conveyor arm two, a conveying pipe two inserted through the middle of the sealing block, a conveying pipe one mounted on the conveyor arm two through the installation sleeve plate, and the conveying pipe one fixedly connected to the connecting pipe;

[0007] A sealing ring is provided in the middle of the second conveying pipe. Multiple spring cylinders are installed circumferentially in the middle of the sealing ring. A driven rod is movably arranged inside the multiple spring cylinders. Multiple grooves are opened on the inner wall of the second conveying pipe. A fastening rib is rotatably connected to the inner side of each of the multiple grooves. The multiple driven rods are movably connected to the fastening ribs respectively. A triangular plate is fixedly connected to one side wall of each of the multiple fastening ribs.

[0008] Through the above technical solution, by adjusting the angle of conveyor arm one, the movement of conveyor arm two can drive the conveying angle between conveyor pipe two and conveyor pipe one. When the vertical angle of conveying pipe two is large, the falling speed of concrete is faster, causing a large amount of rising gas to move towards conveyor pipe one. In order to prevent the reaction force of the gas, during the concrete conveying and falling process, the concrete material, along with the pressure conveying, pushes the triangular plate to move and unfold, which in turn drives the fastening rib plate to move. After the fastening rib plate moves, it pushes multiple driven rods to move. After the driven rods move, they are resisted by the spring cylinder. Thus, the unfolding size of multiple triangular plates can be pushed according to the amount of concrete being conveyed, so that the rising gas generated during the falling process is blocked by the triangular plates, reducing the back impact on the conveyed concrete material and improving the uniformity of concrete material conveying.

[0009] Furthermore, multiple linkage rods are movably installed on one side of the mounting plate, and pressure plates are welded to the outer surfaces of the multiple linkage rods. A spring that abuts against the pressure plate is fitted onto the outer surface of the linkage rod.

[0010] Through the above technical solution, as the conveying pressure increases, the movement range of the linkage increases, which in turn drives the pressure plate to squeeze the spring, thereby initially buffering the bends in the concrete conveying process, avoiding impact on the inner wall of the pipeline, and improving the service life.

[0011] Furthermore, a sealing disc is fixedly installed at one end of the first conveying pipe, and multiple linkage rods are interposed with the sealing disc. The multiple linkage rods pass through the sealing disc and enter the inner cavity of the first conveying pipe, and are connected to a buffer cylinder.

[0012] Through the above technical solution, in order to prevent the concrete material from impacting the bend of the conveying pipeline, the buffer cylinder is first in contact with the concrete, and then slides back and forth in the conveying pipeline as the concrete conveying pressure impacts it, so as to reduce the impact on the conveying pipeline when the concrete impacts it.

[0013] Furthermore, the buffer cylinder is slidably disposed on the inner wall of the conveying pipe one, and multiple linkage rods are each fitted with spring two on the outer surface of the inner cavity of the conveying pipe one. Multiple spring two are in contact with the outer surface of the buffer cylinder. One end of the buffer cylinder is fixedly connected to a connecting pipe, which is slidably engaged with the mounting sleeve plate and the sealing disc. One end of the connecting pipe is fixedly connected to an inner sealing sleeve.

[0014] Through the above technical solution, after the buffer cylinder is impacted during the process, the buffer cylinder drives multiple linkage rods to move. The buffer cylinder first comes into contact with the second spring, buffering part of the impact force.

[0015] Furthermore, an outer sealing sleeve is fixedly connected to one end of the second conveying pipe, and one end of the connecting pipe and the inner sealing sleeve is located inside the second conveying pipe. The inner sealing sleeve is slidably disposed with the inner wall of the second conveying pipe, and the inner sealing sleeve and the outer sealing sleeve are in contact and cooperate with each other.

[0016] Through the above technical solution, the buffer cylinder drives the connecting pipe to move, and drives the inner sealing sleeve to slide inside the second conveying pipe. In the original state, the inner sealing sleeve and the outer sealing sleeve are in contact, ensuring the sealing performance, thereby providing secondary buffering and pressure relief at the concrete elbow and avoiding impact on the elbow.

[0017] Furthermore, a hydraulic telescopic rod is rotatably mounted on the outer surface of the first conveyor arm, two support arms are rotatably connected to the outer wall of the first conveyor arm, and two push arms are rotatably connected to the outer wall of the second conveyor arm. Both push arms are rotatably mounted on the inner side of the two support arms, and the extended end of the hydraulic telescopic rod is rotatably connected to the push arms.

[0018] Through the above technical solution, by adjusting the angle of conveyor arm one, and then opening the hydraulic telescopic rod from the external controller, the hydraulic telescopic rod extends or retracts after operation, driving the support arm and the push arm to rotate, thereby driving conveyor arm two to move. After conveyor arm two moves, it drives the pin block to rotate and then rotates on the adapter cylinder.

[0019] The above-described solution of this utility model has at least the following beneficial effects:

[0020] 1. In this utility model, when the vertical angle of the conveying pipe is large, the falling speed of the concrete is faster, causing a large amount of rising gas to move towards the conveying pipe. In order to prevent the reaction force of the gas, during the descent of the concrete, the concrete material is pushed by the pressure conveying to move and unfold the triangular plate, which in turn drives the fastening rib plate to move. After the fastening rib plate moves, it pushes multiple driven rods to move. After the driven rods move, they are resisted by the spring cylinder. Thus, the unfolding size of the multiple triangular plates can be pushed according to the amount of concrete being conveyed, so that the rising gas generated during the descent is blocked by the triangular plates, reducing the back impact on the conveyed concrete material and improving the uniformity of concrete material conveying.

[0021] 2. This utility model increases the movement range of the linkage rod by increasing the conveying pressure, which in turn drives the pressure plate to squeeze the spring, thus initially buffering the bend in the concrete conveying process, avoiding impact on the inner wall of the pipe, and improving the service life. In order to prevent the concrete material from impacting the bend of the conveying pipe, the buffer cylinder is first in contact with the concrete, and slides back and forth in the conveying pipe as the concrete conveying pressure impacts it, ensuring that the impact on the conveying pipe is reduced when the concrete impacts. During the process, after the buffer cylinder is impacted, the buffer cylinder drives multiple linkage rods to move. The buffer cylinder first abuts against the spring, buffering part of the impact force. The buffer cylinder drives the connecting pipe to move and drives the inner sealing sleeve to slide in the conveying pipe. In the original state, the inner sealing sleeve and the outer sealing sleeve are in contact, thus providing secondary buffering and pressure reduction at the concrete bend, avoiding impact at the bend.

[0030] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0031] like Figures 1 to 6 As shown, an embodiment of this utility model provides a concrete deep pouring device for water conservancy engineering construction, including a conveyor arm 1, a transition cylinder 3 rotatably connected to one end of the conveyor arm 1, a pin block 4 fixedly connected to the outer surface of the transition cylinder 3, a conveyor arm 2 10 rotatably mounted on the transition cylinder 3 through the pin block 4, a connecting pipe 5 inserted through the middle of the transition cylinder 3, a sealing and fixing block 12 fixedly connected to one side wall of the conveyor arm 2 10, an installation sleeve plate 9 fixedly connected to one side wall of the conveyor arm 2 10, a conveying pipe 2 11 inserted through the middle of the sealing and fixing block 12, a conveying pipe 1 8 installed on the conveyor arm 2 10 through the installation sleeve plate 9, and the conveying pipe 1 8 fixedly connected to the connecting pipe 5.

[0032] A sealing ring 24 is provided in the middle of the second conveying pipe 11. Multiple spring cylinders 23 are installed in a ring around the middle of the sealing ring 24. A driven rod 25 is movably installed inside the multiple spring cylinders 23. Multiple grooves are opened on the inner wall of the second conveying pipe 11. Fastening ribs 26 are rotatably connected to the inner side of each groove. Multiple driven rods 25 are movably connected to the fastening ribs 26 respectively. Triangular plates 22 are fixedly connected to one side wall of each of the multiple fastening ribs 26. A sealing disc 14 is fixedly installed at one end of the first conveying pipe 8. A hydraulic telescopic rod 2 is rotatably installed on the outer surface of the first conveyor arm 1. Two support arms 6 are rotatably connected to the outer wall of the first conveyor arm 1. Two push arms 7 are rotatably connected to the outer wall of the second conveyor arm 10. The two push arms 7 are rotatably installed inside the two support arms 6. The extended end of the hydraulic telescopic rod 2 is rotatably connected to the push arm 7.

[0033] In this embodiment of the invention, by adjusting the angle of the conveyor arm 1, the conveying angle between the conveyor pipe 11 and the conveyor pipe 8 can be adjusted by the movement of the conveyor arm 10. When the vertical angle of the conveyor pipe 11 is large, the concrete falls faster, causing a large amount of rising gas to move towards the conveyor pipe 8. To prevent the reaction force of the gas, during the descent of the concrete, the concrete material is pushed by the pressure conveying to move and unfold the triangular plate 22, which in turn drives the fastening rib plate 26 to move. After the fastening rib plate 26 moves, it pushes multiple driven rods 25 to move. After the driven rods 25 move, they are abutted by the spring cylinder 23. Thus, the unfolding size of the multiple triangular plates 22 can be adjusted according to the amount of concrete being conveyed, so that the rising gas generated during the descent is blocked by the triangular plates 22, reducing the counter-impact on the conveyed concrete material and improving the uniformity of the concrete material conveying.

[0034] like Figures 1 to 3 As shown, multiple linkage rods 15 are movably installed on one side of the mounting plate 9. Each linkage rod 15 has a pressure plate 17 welded to its outer surface. A spring 16, which abuts against the pressure plate 17, is fitted onto the outer surface of each linkage rod 15. The multiple linkage rods 15 are interposed with the sealing plate 14. The multiple linkage rods 15 pass through the sealing plate 14 and enter the inner cavity of the conveying pipe 8, where they are connected to a buffer cylinder 21. The buffer cylinder 21 slides against the inner wall of the conveying pipe 8. A spring 20 is fitted onto the outer surface of each linkage rod 15 located within the inner cavity of the conveying pipe 8. Each spring 20 is in contact with the outer surface of the buffer cylinder 21. One end of the buffer cylinder 21 is fixedly connected to a connecting pipe 13. The connecting pipe 13 is in sliding contact with the mounting sleeve 9 and the sealing disc 14. One end of the connecting pipe 13 is fixedly connected to an inner sealing sleeve 18. One end of the conveying pipe 21 is fixedly connected to an outer sealing sleeve 19. One end of the connecting pipe 13 and the inner sealing sleeve 18 are located inside the conveying pipe 21. The inner sealing sleeve 18 is slidably disposed with the inner wall of the conveying pipe 21. The inner sealing sleeve 18 and the outer sealing sleeve 19 are in contact with each other.

[0035] In this embodiment of the utility model, as the conveying pressure increases, the movement amplitude of the linkage rod 15 increases, which in turn drives the pressure plate 17 to squeeze the spring 16, thereby initially buffering the bend in the concrete conveying process, avoiding impact on the inner wall of the pipe, and improving the service life. In order to prevent the concrete material from impacting the bend of the conveying pipe, the buffer cylinder 21 is first in contact with the concrete, and as the conveying pressure of the concrete impacts the buffer cylinder 21, it slides back and forth in the conveying pipe 8, ensuring that the impact on the conveying pipe is reduced when the concrete impacts. During the process, after the buffer cylinder 21 is impacted, the buffer cylinder 21 drives multiple linkage rods 15 to move. The buffer cylinder 21 first abuts against the spring 20, buffering part of the impact force. The buffer cylinder 21 drives the connecting pipe 13 to move, and drives the inner sealing sleeve 18 to slide in the conveying pipe 11. In the original state, the inner sealing sleeve 18 is in contact with the outer sealing sleeve 19 to ensure the sealing, thereby providing secondary buffering and pressure reduction at the concrete bend and avoiding impact at the bend.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
