Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and more specifically, to a large-volume concrete pouring equipment. Background Technology

[0002] Volumetric concrete pouring is widely used in large-scale infrastructure projects such as high-rise buildings, bridges, and water conservancy projects. The quality of pouring directly affects the stability and service life of the engineering structure.

[0003] Currently, the delivery pipe at the end of a concrete pump truck is usually a straight cylinder. When pouring concrete into right-angled walls, the ordinary straight cylinder delivery pipe has poor adhesion to the right-angled wall. During the pouring process, the concrete slurry tends to accumulate unevenly at the corner of the wall, resulting in quality defects such as honeycomb and pitting at the right-angled area, which affects the structural strength and appearance quality of the wall. Utility Model Content

[0004] Based on the aforementioned issue that the delivery pipe at the end of a concrete pump truck is typically a straight cylinder, when pouring concrete into right-angled walls, the ordinary straight cylinder delivery pipe has poor adhesion to the right-angled wall. During the pouring process, the concrete slurry tends to accumulate unevenly at the corner of the wall, resulting in honeycomb and pitted surface defects at the right-angled area, which affects the structural strength and appearance quality of the wall. Therefore, this utility model proposes a large-volume concrete pouring device.

[0005] The present invention proposes a large-volume concrete pouring equipment, including a conveying hose, a discharge pipe, a rotating sleeve, and a discharge pipe installed at the end of a concrete pump truck for conveying concrete slurry.

[0006] The rotating sleeve is rotatably connected to the end of the conveying hose, and a connection hole is provided on the outer wall of the rotating sleeve;

[0007] The feed pipe is fixedly connected to the end of the rotating sleeve;

[0008] The end of the discharge pipe is fixedly connected to the connection hole. The outer end of the discharge pipe protrudes outward to form a triangular protrusion. During the discharge process, the triangular protrusion abuts against the right-angle wall. The triangular protrusion contacts both sides of the right-angle wall. At this time, a discharge port is formed between the discharge pipe and the right-angle wall.

[0009] Preferably, a fixed sleeve is fixedly connected to the outer wall of the rotating sleeve, a rotating ring is fitted on the outer wall of the fixed sleeve, and a plurality of support rods are fixedly connected to the outer wall of the fixed sleeve, with the ends of the support rods respectively fixedly connected to the outer wall of the rotating ring.

[0010] Preferably, the outer wall of the rotating sleeve has an external connection hole, and a sealing plate is slidably connected to the inner wall of the external connection hole. The sealing plate is used to seal the inner wall of the rotating sleeve.

[0011] Preferably, the inner wall of the rotating sleeve is provided with a slot, and the arc end of the sealing plate is inserted into the slot.

[0012] Preferably, a rubber sealing sheet is fixedly connected to the inner wall of the slot, and the arc end of the sealing plate squeezes the rubber sealing sheet, causing the rubber sealing sheet to be recessed into the slot.

[0013] Preferably, the sealing plate has a gripping hole on the outer side of the rotating sleeve, and the sealing plate has a locking hole on the outer side of the rotating sleeve.

[0014] Preferably, the concrete pouring equipment further includes a fixing block, which is fixedly installed on the outer wall of the rotating sleeve, and a clamping rod is slidably connected to the inner wall of the fixing block, with the bottom end of the clamping rod engaging with a clamping hole.

[0015] Preferably, a limiting ring is fixedly connected to the outer wall of the clamping rod, and the limiting ring is located below the fixing block.

[0016] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0017] By incorporating a rotating sleeve, a feeding pipe, and a discharge pipe, the drawbacks of traditional straight-tube feeding pipes in right-angle wall pouring are overcome. The rotating sleeve allows for flexible adjustment of the angles of the feeding pipe and discharge pipe, enabling the triangular protrusion at the outer end of the discharge pipe to closely fit both sides of the right-angle wall, forming a discharge port. Compared to traditional straight-tube feeding pipes, the fit is significantly improved. During pouring, the concrete slurry can be evenly poured into the corner of the right-angle wall through the discharge port, avoiding uneven accumulation of concrete slurry at the corner. This prevents honeycomb and pitting defects at the right-angle location, improving the structural strength and appearance quality of the wall. Attached Figure Description

[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In this utility model, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a large-volume concrete pouring equipment includes a conveying hose 1, a discharge pipe 2, a rotating sleeve 3 and a discharge pipe 8. The conveying hose 1 is installed at the end of a concrete pump truck for conveying concrete slurry. The rotating sleeve 3 is rotatably connected to the end of the conveying hose 1. A connection hole 4 is opened on the outer wall of the rotating sleeve 3. The discharge pipe 2 is fixedly connected to the end of the rotating sleeve 3.

[0027] The end of the discharge pipe 8 is fixedly connected to the connection hole 4. The outer end of the discharge pipe 8 protrudes outward to form a triangular protrusion 9. During the discharge process, the triangular protrusion 9 abuts against the right-angle wall. The triangular protrusion 9 contacts both sides of the right-angle wall. At this time, a discharge port 19 is formed between the discharge pipe 8 and the right-angle wall.

[0028] The rotating sleeve 3 is rotatably connected to the conveying hose 1, allowing the discharge pipe 2 and the discharge pipe 8 to flexibly adjust their angles to fit right-angle walls in different locations. The triangular protrusion 9 at the outer end of the discharge pipe 8 contacts the two sides of the right-angle wall to form a discharge port 19. Compared with the traditional straight-cylinder discharge pipe, it can better fit the right-angle wall, allowing the concrete slurry to accumulate evenly at the corner of the wall, effectively avoiding quality defects such as honeycomb and pitting, and improving the structural strength and appearance quality of the wall at the right angle.

[0029] In this embodiment, as Figure 1 As shown, a fixed sleeve 10 is fixedly connected to the outer wall of the rotating sleeve 3, a rotating ring 11 is sleeved on the outer wall of the fixed sleeve 10, and multiple support rods 12 are fixedly connected to the outer wall of the fixed sleeve 10. The ends of the support rods 12 are respectively fixedly connected to the outer wall of the rotating ring 11.

[0030] The fixed sleeve 10, rotating ring 11 and support rod 12 provide stable rotation support for the rotating sleeve 3, making the rotating sleeve 3 rotate more smoothly and flexibly, and making it easier for operators to adjust the angle of the feed pipe 2 and the discharge pipe 8.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the outer wall of the rotating sleeve 3 has an external connection hole 5, and a sealing plate 13 is slidably connected to the inner wall of the external connection hole 5. The sealing plate 13 is used to seal the inner wall of the rotating sleeve 3.

[0032] The inner wall of the rotating sleeve 3 is provided with a slot 6, and the arc end of the sealing plate 13 is inserted into the slot 6.

[0033] The arc end of the sealing plate 13 is inserted into the slot 6, which allows the sealing plate 13 to be securely installed on the inner wall of the rotating sleeve 3.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, a rubber sealing sheet 7 is fixedly connected to the inner wall of the slot 6. The arc end of the sealing plate 13 squeezes the rubber sealing sheet 7, causing the rubber sealing sheet 7 to be recessed into the slot 6.

[0035] When the sealing plate 13 is slid outward from the external hole 5, the rubber sealing piece 7 in the slot 6 rebounds and seals the slot 6, preventing concrete slurry from flowing into the slot 6 and causing the sealing plate 13 to be unable to be fully inserted into the slot 6, resulting in a weakened sealing effect.

[0036] In this embodiment, as Figure 5 As shown, the sealing plate 13 has a gripping hole 14 on the outside of the rotating sleeve 3, and a locking hole 15 on the outside of the rotating sleeve 3.

[0037] The gripping hole 14 on the sealing plate 13 makes it easy for operators to insert or remove the sealing plate 13, making operation convenient; the locking hole 15 cooperates with the locking rod 17 to firmly fix the sealing plate 13 on the rotating sleeve 3, preventing the sealing plate 13 from loosening or falling off during the pouring process and ensuring the stability of the seal.

[0038] In this embodiment, as Figure 5 As shown, the concrete pouring equipment also includes a fixing block 16, which is fixedly installed on the outer wall of the rotating sleeve 3. A clamping rod 17 is slidably connected to the inner wall of the fixing block 16, and the bottom end of the clamping rod 17 is engaged with the clamping hole 15.

[0039] The fixing block 16, the clamping rod 17, and the clamping hole 15 of the sealing plate 13 cooperate to improve the stability of the sealing plate 13 during installation.

[0040] In this embodiment, as Figure 5As shown, a limiting ring 18 is fixedly connected to the outer wall of the locking rod 17, and the limiting ring 18 is located below the fixing block 16. The limiting ring 18 can prevent the locking rod 17 from sliding upward during use.

[0041] When pouring large volumes of concrete, the concrete pump truck delivers the concrete slurry through the conveying hose 1.

[0042] Insert the sealing plate 13 into the inner wall of the rotating sleeve 3 along the external hole 5. Insert the arc end of the sealing plate 13 into the slot 6 and squeeze the rubber sealing sheet 7 to make it concave. The operator can easily operate the sealing plate 13 through the grip hole 14. After it is inserted into place, slide the locking rod 17 down from the inner wall of the fixing block 16 so that its bottom end engages with the locking hole 15 of the sealing plate 13 to fix the sealing plate 13. The limiting ring 18 can prevent the locking rod 17 from falling off and ensure that the sealing plate 13 is firmly sealed.

[0043] Since the rotating sleeve 3 is rotatably connected to the end of the conveying hose 1, the operator can rotate the rotating sleeve 3 according to the position and angle of the right-angle wall to adjust the discharge pipe 2 and the discharge pipe 8 fixed in the connecting hole 4 of the rotating sleeve 3 to the appropriate position.

[0044] The triangular protrusion 9 at the outer end of the discharge pipe 8 can fit against both sides of the right-angle wall to form a discharge port 19 with the wall.

[0045] The concrete slurry is delivered through the conveying hose 1, rotating sleeve 3, and discharge pipe 2, and then evenly poured into the right-angle wall through the discharge pipe 8 and discharge port 19.

[0046] If the discharge pipe 8 is not needed, the sealing plate 13 can be slid outward from the external hole 5. The rubber sealing sheet 7 in the slot 6 will rebound and seal the slot 6, preventing concrete slurry from flowing into the slot 6 and causing the sealing plate 13 to be unable to be fully inserted into the slot 6, resulting in a weakened sealing effect.

[0047] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
