Description

Technical Field

[0001] This invention relates to the field of concrete construction technology, and in particular to equipment for large-volume concrete pouring. Background Technology

[0002] Mass concrete refers to concrete with a geometric dimension of not less than one meter. During pouring, this type of concrete is prone to shrinkage due to temperature changes caused by material hydration, making it susceptible to cracking. Therefore, layered pouring is often used when pouring mass concrete to effectively dissipate internal heat quickly and reduce the likelihood of cracking after solidification. Formwork is typically used to define the pouring area. However, a common current method involves directly pouring concrete from the discharge pipe at the rear of the concrete mixer truck into the pre-built formwork.

[0003] Some existing concrete pump trucks employ a manual layering and vibration process, which requires significant manpower and machinery, increasing equipment and labor costs. Furthermore, manual operation results in uneven layering, affecting the effectiveness of layered pouring. Additionally, the pumping pipe and delivery pipe of concrete pump trucks are typically secured with clamps and bolts, making disassembly and reconnection difficult, further reducing construction efficiency. Moreover, existing concrete pouring inlets consist of a funnel structure, lifted by an external lifting device, with the lower end aligned with the pouring location. Concrete enters the funnel's inner side. When the funnel becomes clogged, the lifting device needs to rock it up and down to clear the blockage. This method is problematic in confined spaces where there is insufficient space to accommodate the lifting device, making pouring extremely cumbersome. Additionally, after a period of time, the concrete tends to harden, causing blockages at the inlet. Therefore, to address these issues, a large-volume concrete pouring device is proposed. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a large-volume concrete pouring device, which aims to improve the problems of low efficiency in large-volume concrete pouring and difficulty in quickly disassembling and installing the pouring pipe, as well as easy blockage of the pouring pipe opening, caused by the need for manual pouring and vibration in the existing pouring equipment.

[0009] As a further description of the above technical solution: the bottom end of the conveying pipe is engaged with the top end of the casting pipe, and the inside of the limiting sleeve is slidably connected to the outside of the casting pipe.

[0010] As a further description of the above technical solution: the vibrating rod is externally slidably connected to the inner wall of the groove, the bottom end of the support plate is slidably connected to the top end of the limiting plate, and the top end of the vibrating rod is externally fixedly connected to the bottom end of the support plate on the side away from the protrusion.

[0011] As a further description of the above technical solution: the outer side of the retaining ring engages with the outer side of the retaining hook, the outer side of the first arc-shaped strip contacts the outer side of the casting pipe, the outer side of the second arc-shaped strip contacts the outer side of the material conveying pipe, and the outer side of the second arc-shaped strip contacts the outer side of the casting pipe.

[0015] The present invention has the following beneficial effects:

[0016] 1. In this invention, the concrete pouring process involves a crane activating a conveying system to deliver concrete from a material delivery pipe through a pouring pipe to a designated location. Simultaneously, based on the concrete flow rate within the pouring pipe, a hydraulic rod is activated, raising a limiting sleeve. This action, in turn, pulls a support plate, causing the vibrator to adjust its spacing around the pouring pipe. This allows for simultaneous pouring and compaction. This overcomes the shortcomings of existing technologies that require extensive equipment and manpower for multiple pouring processes, ensuring comprehensive equipment coverage of the concrete pouring area and reducing internal porosity and defects.

[0017] 2. In this invention, the pouring pipe is initially connected by inserting it into the delivery pipe. Then, the second arc-shaped strip is aligned with the first arc-shaped strip, wrapping around the connecting ring of the delivery pipe and closing the connecting sleeve of the pouring pipe. Finally, the retaining ring is engaged with the hook and locked by activating the second hydraulic rod, thus achieving rapid connection. This design makes the concrete pouring process more continuous. When it is necessary to replace or extend the pouring pipe, the device can quickly complete the connection operation, avoiding concrete interruption caused by excessive connection time and ensuring the continuity of the pouring work.

[0018] 3. In this invention, the concrete impact roller at the outlet of the pouring pipe, in conjunction with the vibrating rod, drives the bottom of the pouring pipe to vibrate. This multiple vibrations cause the connecting roller to pull the pull plate in a reciprocating motion. This process, combined with the action of springs one and two, increases the amplitude and frequency of the unblocking cylinder's vertical sliding. This design ensures continuous and uniform concrete pouring, avoiding construction delays caused by blockages. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figures 1 to 3 This invention provides an embodiment of a large-volume concrete pouring equipment, including a pouring crane 1 and a pouring pipe 3. A conveying pipe 2 is provided on the outside of the pouring crane 1, and the bottom end of the conveying pipe 2 engages with the top end of the pouring pipe 3. The pouring crane 1 is the core component of the entire equipment, responsible for conveying the mixed concrete to the required location. The pouring crane 1 conveys the concrete into the pouring pipe 3 through the conveying pipe 2, and then the boom pours the concrete to the required location.

[0029] refer to Figure 2 , Figure 3 Two hydraulic rods 4 are fixedly connected to the outside of the casting pipe 3, and are located at the bottom of the outer side of the casting pipe 3. A limiting sleeve 5 is fixedly connected to the drive end of each hydraulic rod 4, used to drive the limiting sleeve 5 to rise or fall. The limiting sleeve 5 is internally slidably connected to the outside of the casting pipe 3. The two hydraulic rods 4 drive the limiting sleeve 5 to rise or fall outside the casting pipe 3, thereby adjusting the spacing of the bottom connecting components.

[0030] The limiting sleeve 5 is externally fixedly connected to four protruding strips 6. Rotating rods 7 are rotatably connected to the upper and lower sides of each protruding strip 6. The protruding strips 6 are used to position the rotating rods 7, increasing the connection between the limiting sleeve 5 and the rotating rods 7. Connecting strips 8 are fixedly connected to the ends of the two rotating rods 7 furthest from the casting pipe 3. The connecting strips 8 move with the limiting sleeve 5 as support via the rotating rods 7. A support plate 9 is fixedly connected to the side of the connecting strip 8 furthest from the rotating rods 7. The support plate 9 can be moved horizontally by the hydraulic rod 4 activated via the connecting strip 8.

[0031] A motor 12 is fixedly connected to the side of the support plate 9 away from the rotating rod 7. A vibrating rod 13 is fixedly connected to the drive end of the motor 12. The support plate 9 serves as the foundation for the installation of the motor 12 and the vibrating rod 13. When the support plate 9 moves, it drives the motor 12 and the vibrating rod 13 to move together. The vibrating rod 13 is externally slidably connected to the inner wall of the groove 11, and its top end is externally fixedly connected to the bottom end of the support plate 9 away from the protrusion 6. The vibrating rod 13 is driven and confined within the groove 11 by the support plate 9, allowing it to slide with the pouring pipe 3 as the center. When the vibrating rod 13 is working, it can improve the density and quality of the concrete.

[0032] The bottom outer end of the pouring pipe 3 is provided with a limiting component to limit the distance between the vibrating rods 13. The limiting component includes a limiting disc 10, the inner wall of which is fixedly connected to the bottom outer end of the pouring pipe 3. The bottom end of the support plate 9 is slidably connected to the top end of the limiting disc 10. The top end of the limiting disc 10 has four grooves 11. The limiting disc 10 is used to limit the distance between the vibrating rods 13. The grooves 11 in its middle are used to limit the spacing between the vibrating rods 13.

[0033] refer to Figure 4 , Figure 5 Two arc-shaped strips 14 are fixedly connected to the outside of the material conveying pipe 2, and are fixed to the opening of the material conveying pipe 2. The outside of the arc-shaped strips 14 contacts the outside of the casting pipe 3, and the arc-shaped strips 14 wrap around and lock the outside of the casting pipe 3. A connecting block 15 is fixedly connected to the front end of the two arc-shaped strips 14, and one end of the two arc-shaped strips 14 is fixed together by the connecting block 15. A hydraulic rod 16 is fixedly connected to the right side of the connecting block 15, and the connecting block 15 supports the hydraulic rod 16, and the hydraulic rod 16 is fixedly inclined in the middle of the connecting block 15. A retaining ring 17 is fixedly connected to the driving end of the hydraulic rod 16. The hydraulic rod 16 pushes the retaining ring 17 to lock the hook 21, thereby realizing the rapid docking of the casting pipe 3 and the material conveying pipe 2.

[0034] The outer surface of the retaining ring 17 engages with the outer surface of the hook 21, and the retaining ring 17, fitted onto the outer surface of the hook 21, secures the arc-shaped strip 14 and the connecting block 15 together. A central shaft 19 is fixedly connected to the left end of each of the two arc-shaped strips 14. The central shaft 19 is designed to secure both the two arc-shaped strips 14 and the two arc-shaped strips 20. The outer surface of the central shaft 19 is rotatably connected to the two arc-shaped strips 20. The central shaft 19 is a component fixed to the left end of each of the two arc-shaped strips 14, used for rotatably connecting the two arc-shaped strips 20.

[0035] The outer surface of the second arc-shaped strip 20 contacts the outer surface of the conveying pipe 2, enabling rapid docking between the casting pipe 3 and the conveying pipe 2. The outer surface of the second arc-shaped strip 20 also connects to the outer surface of the casting pipe 3, wrapping around the top end of the casting pipe 3. A hook 21 is fixedly connected to the front end of the second arc-shaped strip 20, used to lock the retaining ring 17. A docking ring 23 is fixedly connected to the bottom end of the conveying pipe 2, with a diameter larger than that of the top end of the conveying pipe 2. A docking sleeve 24 is fixedly connected to the outer surface of the top end of the casting pipe 3, with the docking sleeve 24 having the same diameter as the docking ring 23.

[0036] Multiple locking blocks 18 are fixedly connected to the outer middle of the two arc-shaped strips 14. The locking blocks 18 are designed to increase the connection between the two arc-shaped strips 14 and increase the clamping force of the arc-shaped strips 14. The outer side of the mating ring 23 engages with the inner wall of the locking block 18, and the outer side of the mating sleeve 24 engages with the inner wall of the locking block 18. Multiple central shafts 19 are fixedly connected to the outer middle of the two arc-shaped strips 14. The locking blocks 18 wrap around the mating ring 23 and the mating sleeve 24. Multiple locking blocks 22 are fixedly connected to the outer middle of the two arc-shaped strips 14. The outer side of the mating ring 23 engages with the inner wall of the locking block 22, and the outer side of the mating sleeve 24 engages with the inner wall of the locking block 22. The locking blocks 22 wrap around the mating ring 23 and the mating sleeve 24.

[0037] refer to Figure 6 A ball-and-stick cover 25 is fixedly connected to the bottom of the casting pipe 3. The ball-and-stick cover 25 is a hemispherical cover that protrudes from the opening of the casting pipe 3. A sleeve 26 is fixedly connected to the middle of the ball-and-stick cover 25. The middle part of the sleeve 26 supports the opening of the casting pipe 3. The top of the casting pipe 3 is spherical and coated with a lubricating coating to prevent concrete from sticking to the wall. A rotating wheel rod 27 is rotatably connected to the middle of the bottom of the sleeve 26. The rotating wheel rod 27 consists of a round rod and a horizontal rotating wheel.

[0038] A connecting roller 28 is fixedly connected to the end of the rotating rod 27 away from the ball cover 25. Rotation of the rotating rod 27 pulls the connecting roller 28 to rotate 360 ​​degrees around the circular rod of the rotating rod 27. A transmission rod 29 is rotatably connected to the top of the connecting roller 28, and a pull plate 30 is fixedly connected to the outside of the top of the transmission rod 29. The rotating rod 27 pulls the transmission rod 29 up and down along the inner wall of the unclogging cylinder 33 via the connecting roller 28. A spring 31 is sleeved on the outside of the transmission rod 29, and the spring 31 is positioned at the bottom of the inner wall of the unclogging cylinder 33.

[0039] The top end of spring 31 is fixedly connected to the bottom end of pull plate 30, and the bottom end of spring 31 is fixedly connected to the bottom end of the inner wall of drain cylinder 33. When pull plate 30 is driven downward by transmission rod 29, it will be pulled, squeezed and pushed drain cylinder 33 downward synchronously. Then, it will use its own elasticity to drive drain cylinder 33 and pull plate 30 to return to their original positions, thereby increasing the up-and-down sliding amplitude and frequency of drain cylinder 33. A limit ring 32 is slidably connected inside sleeve 26. Drain cylinder 33 is fixedly connected to the middle of limit ring 32. Limit ring 32 is fixed to the outside of drain cylinder 33, limiting the linear sliding of drain cylinder 33. A second spring 34 is sleeved on the outside of the unclogging cylinder 33. The bottom end of the second spring 34 is fixedly connected to the top of the inner wall of the sleeve 26 and the bottom end of the second spring 34 is fixedly connected to the top of the limiting ring 32. When the unclogging cylinder 33 is indirectly driven downward by the pull plate 30, it will pull the second spring 34. When the pull plate 30 returns to its original position, the elastic force of the second spring 34 will increase the sliding amplitude and frequency of the unclogging cylinder 33 again, so as to achieve high-frequency vibration of the unclogging cylinder 33 to unclog the outlet of the pouring pipe 3.

[0040] Working principle: During use, the activated pouring crane 1 delivers the mixed concrete from the delivery pipe 2 into the pouring pipe 3, and the boom of the pouring crane 1 is used to irrigate the area to be poured. During the pouring process, the user can adjust the spacing of the vibrators 13 around the outlet of the pouring pipe 3 according to the flow rate of the concrete out of the pouring pipe 3, so as to ensure that the concrete at different locations of the pouring pipe 3 is fully vibrated, thereby improving the density and quality of the concrete and reducing the generation of internal pores and defects.

[0041] Regarding the adjustment of the spacing of the motor 12, the hydraulic rod 4 can be activated to drive the limiting sleeve 5 to rise. This, in turn, the rotating rod 7 connected to the limiting sleeve 5 pulls the support plate 9 to move horizontally along the inner wall of the slide 11 towards the limiting sleeve 5. While the support plate 9 moves in a straight line, the support plate 9 will simultaneously press against the slide 11 and slide, thereby adjusting the spacing between the vibrating rods 13. This allows the vibrating rods 13 to more comprehensively cover the concrete pouring area while the pouring pipe 3 is pouring, ensuring that the concrete in different locations is fully vibrated, improving the density and quality of the concrete, and reducing the generation of internal pores and defects.

[0042] Furthermore, when the user needs to connect the pouring pipe 3 and the conveying pipe 2, the pouring pipe 3 can be inserted into the conveying pipe 2, and then the arc-shaped strip 20 can be rotated to align with the arc-shaped strip 14, so that the arc-shaped strip 20 and the arc-shaped strip 14 can wrap around the connecting ring 23 of the conveying pipe 2 and the connecting sleeve 24 of the pouring pipe 3. Then, the retaining ring 17 is engaged with the hook 21, and the hydraulic rod 21 is activated to lock it. This allows for quick connection of the pouring pipe 3 and the conveying pipe 2, making the concrete pouring process more continuous. It also allows for rapid connection when replacing or extending the pouring pipe 3, avoiding concrete interruptions caused by excessive connection time and ensuring the continuity of pouring.

[0043] Furthermore, during the pouring of concrete from the outlet of the pouring pipe 3, the liquid concrete impacts the blades of the impeller on one side of the impeller rod 27 when it is poured and discharged. This causes the impeller rod 27 to rotate rapidly due to the impact force. As the impeller rod 27 rotates, it drives the connecting roller 28 to rotate clockwise and pulls the pull plate 30 to move up and down. When the pull plate 30 moves up and down, it first pulls the spring 31 to compress it, and then pulls the spring 34 of the unblocking cylinder 33 and the limiting ring 32 to stretch it. When the connecting roller 28 rotates and resets, the spring 31 will use its own elasticity to drive the pull plate 30 to slide quickly inside the unblocking cylinder 33. Due to the rapid sliding of the pull plate 30, the pull plate 30 will rub against the inside of the unblocking cylinder 33 and, in conjunction with the elastic pull of the spring 34, cause the unblocking cylinder 33 to extend and retract multiple times at the outlet of the pouring pipe 3, thereby impacting the concrete at the outlet of the pouring pipe 3 and effectively preventing blockage at the outlet of the pouring pipe 3.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
