Description

Technical Field

[0001] This utility model relates to the technical field of pumped concrete buffer structure, specifically to a high-drop pumped concrete anti-segregation buffer device. Background Technology

[0002] Pumped concrete pouring has become the mainstream method for concrete pouring. It utilizes concrete pumps and associated pump pipes to deliver large quantities of concrete to pouring chambers for large concrete components such as walls, columns, slabs, and beams, significantly improving construction efficiency. Patent number CN202320803529.1 discloses a pumped concrete buffer device for protecting pouring chambers. This device uses a buffer plate at the outlet of the concrete pump pipe to withstand the direct impact of concrete. Concrete flowing down from the buffer plate loses kinetic energy, allowing it to fall freely into the pouring chamber rather than be forced to flow, greatly reducing the flow velocity and preventing direct impact from damaging weaker or less securely fixed components within the pouring chamber. However, during the use of this pumped concrete buffer device, the buffer plate is subjected to significant impact force, which is fed back to the concrete pump pipe, potentially affecting its performance. Therefore, we propose a high-drop pumped concrete anti-segregation buffer device. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a buffer device for preventing segregation in high-drop pumped concrete. The technical solution adopted by this utility model to solve its technical problem is a high-drop pumped concrete anti-segregation buffer device, including a pump pipe body. The outer peripheral surface of the pump pipe body is bolted with a clamp plate for support, and the outer peripheral surface of the clamp plate is integrally constructed with a ring seat for support. There are multiple sets of ring seats. A screw for support is inserted into the inner side of the ring seat, and a nut body that abuts against the ring seat is screwed on the outer periphery of the screw. The discharge end of the pump pipe body is clamped with a cylinder seat connected to the screw, and a ring cover for guiding material is slidably installed on the outer periphery of the cylinder seat. The inner side of the ring cover is equipped with a flat ball plate corresponding to the discharge end of the pump pipe body through an inclined rod. The outer circumference of the cylindrical base is integrally constructed with ear seats for auxiliary support, and there are multiple sets of ear seats. The top surface of the ring cover is equipped with a vertical rod that is inserted and connected to the ear seats, and there are multiple sets of vertical rods. The top surface of the vertical rod is screwed with a screw seat for limiting, and there are multiple sets of screw seats. Compression springs located on the outer circumference of the vertical rod are installed between the screw seat and the ear seat and between the ear seat and the ring cover.

[0004] By adopting the above technical solution, in the process of using the anti-segregation buffer device for high-drop pumped concrete, the clamp plate can be installed on the side of the outer periphery of the pump pipe near the discharge end using bolts. Then, the cylinder seat can be easily connected to the discharge end of the pump pipe. The stepped groove inside the cylinder seat can be engaged with the corner of the discharge end of the pump pipe. At the same time, multiple sets of screws on the top of the cylinder seat can be inserted into the ring seat on the clamp plate. The nut body and the screws are screwed together to lock and fix the clamp plate and the cylinder seat. Then, the ring cover body that is slidably installed on the outer periphery of the cylinder seat can operate and can be used in conjunction with the internal flat ball plate to buffer the concrete discharged from the pump pipe and reduce the situation of concrete splashing everywhere. This allows the concrete to be poured or transported more stably. The buffer structure is easy to disassemble and replace for maintenance. During the use of the ring cover and the flat spherical plate, the vertical rod at the top of the ring cover can easily slide and engage with the lugs on the cylinder seat. The compression spring between the lugs and the ring cover can provide a certain buffering performance for the ring cover. At the same time, when the flat spherical plate is impacted and causes the ring cover to slide along the cylinder seat, the vertical rod is forced to slide down along the lugs and cause the rotating seat to compress the compression spring between the rotating seat and the lugs, so that the ring cover can be further buffered. This allows the ring cover and the flat spherical plate inside to more stably buffer the concrete and prevent segregation, making the buffer device more stable to use and easy to disassemble and maintain.

[0005] Specifically, the outer circumference of the cylinder base is integrally constructed with ear plates for support, and there are multiple sets of ear plates. A shock absorber for buffering is assembled between the ear plates and the ring cover.

[0006] By adopting the above technical solution, the shock absorber between the outer peripheral ear plate of the cylinder seat and the ring cover can assist the compression spring in its use, thereby enabling the buffer body and the flat spherical plate to buffer the concrete more stably.

[0007] Specifically, a groove is provided on the outer periphery of the cylinder near the bottom end, and a C-shaped ring for preventing detachment is engaged inside the groove.

[0008] By adopting the above technical solution, the C-shaped ring that is snapped into the groove on the outer periphery of the cylinder seat provides a certain limiting performance for the ring cover body that slides on the outer periphery of the cylinder seat, thereby further reducing the situation where the ring cover body and the cylinder seat separate from each other.

[0009] Specifically, the outer periphery of the vertical rod is provided with an arc-shaped groove that matches the inner periphery of the ear seat, and there are multiple sets of arc-shaped grooves.

[0010] By adopting the above technical solution, the arc-shaped groove on the outer periphery of the vertical rod can easily fit with the protrusion on the inner periphery of the ear seat, so that the vertical rod can be more stably inserted into and slidably connected with the ear seat.

[0011] Specifically, both the inner circumferential surface of the cylinder base and the inner circumferential surface of the ring cover are bonded with protective rubber rings.

[0012] By adopting the above technical solution, the rubber ring has good elasticity, thereby improving the stability and tightness of the connection between the cylinder seat and the pump pipe body, and reducing the damage caused by the friction between the ring cover and the cylinder seat.

[0013] Specifically, a corrugated pipe for protection is installed between the pump pipe body and the ring cover body.

[0014] By adopting the above technical solution, the corrugated pipe is easy to extend and retract, which facilitates the protection of the structure between the pump pipe body and the ring cover body, making the structure between the two more stable for use.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The technical solution of this application, through the design of clamp plate, ring seat, screw, nut body, cylinder seat, ring cover body and flat spherical plate, allows for the use of a high-drop pumped concrete anti-segregation buffer device. The clamp plate is first installed on the outer periphery of the pump pipe near the discharge end using bolts. Then, the cylinder seat easily engages with the discharge end of the pump pipe. The stepped groove inside the cylinder seat engages with the corners of the discharge end of the pump pipe. Simultaneously, multiple sets of screws on the top of the cylinder seat can be simultaneously inserted into the ring seat on the clamp plate, and the nut body and screws are screwed together to lock and fix the clamp plate and cylinder seat. The ring cover body, slidably installed on the outer periphery of the cylinder seat, can then operate and work in conjunction with the internal flat spherical plate. This facilitates buffering of the concrete discharged from the pump pipe while reducing concrete splashing, allowing for more stable pouring or delivery of concrete. Furthermore, the buffer structure is easy to disassemble, replace, and maintain.

[0016] 2. The technical solution of this application, through the design of ear seats, vertical rods, rotating seats, and compression springs, allows the vertical rod at the top of the ring cover to easily engage and slide with the ear seats on the cylindrical seat during the use of the ring cover and the flat spherical plate. The compression spring between the ear seats and the ring cover provides a certain buffering performance for the ring cover. At the same time, when the flat spherical plate is impacted and causes the ring cover to slide along the cylindrical seat, the vertical rod is forced to slide down along the ear seats and cause the rotating seat to compress the compression spring between the rotating seat and the ear seats, so that the ring cover can be further buffered. This allows the ring cover and the flat spherical plate inside to more stably buffer the concrete and prevent segregation, making the buffer device more stable to use and convenient for disassembly and maintenance.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a high-drop pumped concrete anti-segregation buffer device, including a pump pipe body 1. A clamp plate 2 for support is bolted to the outer circumferential surface of the pump pipe body 1. A ring seat 3 for support is integrally formed on the outer circumferential surface of the clamp plate 2, and multiple ring seats 3 are provided. A screw rod 4 for support is inserted into the inner side of the ring seat 3, and a nut body 5 that abuts against the ring seat 3 is screwed onto the outer circumference of the screw rod 4. A cylinder seat 6 connected to the screw rod 4 is clamped at the discharge end of the pump pipe body 1, and a slidable support for... The material guide ring 7 has a flat spherical plate 8 corresponding to the discharge end of the pump pipe 1 mounted on its inner side by a diagonal rod; the outer circumference of the cylinder seat 6 is integrally constructed with an ear seat 9 for auxiliary support, and there are multiple sets of ear seats 9; the top surface of the ring 7 is equipped with a vertical rod 10 that is inserted and connected to the ear seat 9, and there are multiple sets of vertical rod 10; the top surface of the vertical rod 10 is screwed with a rotating seat 11 for limiting, and there are multiple sets of rotating seats 11; a compression spring 12 located on the outer circumference of the vertical rod 10 is installed between the rotating seat 11 and the ear seat 9 and between the ear seat 9 and the ring 7.

[0021] When using the high-drop pumped concrete anti-segregation buffer device, the clamp plate 2 can be installed on the outer periphery of the pump pipe body 1 near the discharge end using bolts. Then, the cylinder seat 6 can be easily connected to the discharge end of the pump pipe body 1. The stepped groove inside the cylinder seat 6 can be engaged with the corner of the discharge end of the pump pipe body 1. At the same time, the multiple sets of screws 4 on the top of the cylinder seat 6 can be simultaneously inserted with the ring seat 3 on the clamp plate 2. The nut body 5 is screwed into the screws 4 to lock and fix the clamp plate 2 and the cylinder seat 6. Then, the ring cover 7 slidably installed on the outer periphery of the cylinder seat 6 can operate and can be used in conjunction with the internal flat ball plate 8 to buffer the concrete discharged from the pump pipe body 1 and reduce the situation of concrete splashing everywhere. This allows the concrete to be poured or transported more stably. The buffer structure is easy to disassemble and replace for maintenance. During the use of the ring cover 7 and the flat spherical plate 8, the vertical rod 10 at the top of the ring cover 7 can easily engage and slide with the lug 9 on the cylinder seat 6. The compression spring 12 between the lug 9 and the ring cover 7 can provide a certain buffering performance for the ring cover 7. At the same time, when the flat spherical plate 8 is impacted and causes the ring cover 7 to slide along the cylinder seat 6, the vertical rod 10 is forced to slide down along the lug 9 and cause the rotating seat 11 to compress the compression spring 12 between the rotating seat 11 and the lug 9, so that the ring cover 7 can be further buffered. This allows the ring cover 7 and the flat spherical plate 8 inside to more stably buffer the concrete and prevent segregation, making the buffer device more stable to use and convenient to disassemble and maintain.

[0022] like Figure 2 As shown, the outer circumference of the cylinder base 6 is integrally constructed with lugs 13 for support, and there are multiple sets of lugs 13. A shock absorber 14 for buffering is assembled between the lugs 13 and the ring cover body 7.

[0023] In use, the shock absorber 14 between the outer peripheral ear plate 13 of the cylinder base 6 and the ring cover 7 can assist the compression spring 12 in its operation, thereby enabling the buffer body and the flat spherical plate 8 to buffer the concrete more stably.

[0024] like Figure 3 As shown, a groove 16 is provided on the outer periphery of the cylinder base 6 near the bottom end, and a C-shaped ring 17 for preventing detachment is engaged inside the groove 16.

[0025] During use, the C-shaped ring 17 that is engaged in the groove 16 on the outer periphery of the cylinder seat 6 provides a certain limiting performance for the ring cover 7 that slides on the outer periphery of the cylinder seat 6, thereby further reducing the possibility of separation between the ring cover 7 and the cylinder seat 6.

[0026] like Figure 2 As shown, the outer periphery of the vertical rod 10 is provided with an arc-shaped groove 15 that fits the inner periphery of the ear seat 9, and there are multiple sets of arc-shaped grooves 15.

[0027] In use, the arc-shaped groove 15 on the outer periphery of the vertical rod 10 can easily fit into the protrusion on the inner periphery of the ear seat 9, so that the vertical rod 10 can be more stably inserted into and slidably connected with the ear seat 9.

[0028] like Figure 2 and Figure 3 As shown, both the inner circumferential surface of the cylinder base 6 and the inner circumferential surface of the ring cover 7 are bonded with protective rubber rings 18.

[0029] When in use, the rubber ring 18 has good elasticity, thereby improving the stability and tightness of the connection between the cylinder seat 6 and the pump pipe body 1, and reducing the damage caused by the friction between the ring cover body 7 and the cylinder seat 6.

[0030] like Figure 1 As shown, a bellows 19 for protection is installed between the pump pipe body 1 and the ring cover body 7.

[0031] When in use, the bellows 19 is easy to extend and retract, which helps to protect the structure between the pump pipe body 1 and the ring cover body 7, making the structure between the two more stable to use.

[0032] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the high-drop pumped concrete anti-segregation buffer device, the clamp plate 2 can be installed on the outer periphery of the pump pipe body 1 near the discharge end using bolts. Then, the cylinder seat 6 can easily connect with the discharge end of the pump pipe body 1. The stepped groove inside the cylinder seat 6 can engage with the corners of the discharge end of the pump pipe body 1. Simultaneously, multiple sets of screws 4 at the top of the cylinder seat 6 can be simultaneously inserted into the ring seat 3 on the clamp plate 2. The nut body 5 is screwed into the screws 4 to lock and fix the clamp plate 2 and the cylinder seat 6. Then, the ring cover 7, which is slidably installed on the outer periphery of the cylinder seat 6, can operate and can cooperate with the internal flat spherical plate 8 to buffer the concrete discharged from the pump pipe body 1 while reducing concrete splashing, thus allowing for more stable pouring or transportation of concrete. Furthermore, the buffer structure is easy to disassemble and replace for maintenance. During the use of the ring cover 7 and the flat spherical plate 8, the vertical rod 10 at the top of the ring cover 7 can easily engage and slide with the lug 9 on the cylinder seat 6. The compression spring 12 between the lug 9 and the ring cover 7 can provide a certain buffering performance for the ring cover 7. At the same time, when the flat spherical plate 8 is impacted and causes the ring cover 7 to slide along the cylinder seat 6, the vertical rod 10 is forced to slide down along the lug 9 and cause the rotating seat 11 to compress the compression spring 12 between the rotating seat 11 and the lug 9, so that the ring cover 7 can be further buffered. This allows the ring cover 7 and the flat spherical plate 8 inside to more stably buffer the concrete and prevent segregation. The shock absorber 14 between the ring cover 7 and the outer circumferential lug 13 of the cylinder seat 6 can be used in conjunction with the compression spring 12, thereby improving the stability and buffering effect of the ring cover 7 and the flat spherical plate 8. This makes the buffer device more stable to use and easy to disassemble and maintain.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
