Description

Technical Field

[0001] This utility model relates to the field of mud circulation, and in particular to a mud circulation device for pile foundation construction that can be quickly adjusted. Background Technology

[0002] In the field of pile foundation construction, the mud circulation system is the core equipment to ensure construction efficiency, pile quality and environmental safety. Its core working principle revolves around the closed-loop process of "extraction-transfer-transportation-recovery". The suction component goes deep into the pile foundation hole to extract the mud carrying drilling cuttings to the transfer structure for temporary storage and buffering. Then, the conveying power equipment (such as circulation pump) transports the mud to the sedimentation tank, slag removal equipment or blending system. After treatment, it is returned to the pile foundation hole to realize the reuse of mud.

[0003] However, existing mud circulation devices for pile foundation construction often employ a "fixed installation plus single-position extraction" design for the suction components. Once installed and debugged, the position is fixed, making it impossible to flexibly adjust the suction position according to the dynamically changing mud level and concentration distribution within the pile hole. This easily leads to problems such as insufficient suction and overflow when the mud level is too high, or the components running dry when the mud level is too low, or the inability to specifically extract high-concentration slag-containing mud. This restricts the adaptability of the extraction process. Secondly, the "extraction-transfer-transport" process suffers from poor power coordination. Some devices rely on a single pump for both extraction and transport, resulting in pressure interference and unstable flow rates. Some multi-power devices require individual debugging and control, making synchronous linkage impossible. Furthermore, the fixed connection between the transfer structure and the suction and transport components makes it easy for pipe bending and pulling to occur during suction position adjustments, causing mud retention and pipe leakage. To address these issues, we propose a rapidly adjustable mud circulation device for pile foundation construction. Utility Model Content

[0004] The main objective of this invention is to provide a rapidly adjustable mud circulation device for pile foundation construction, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rapidly adjustable mud circulation device for pile foundation construction includes a first fixed ring and a second fixed ring. Multiple reinforcing ribs are fixedly connected between the first and second fixed rings. A mud transfer cylinder is rotatably connected between the first and second fixed rings on the inner side of each reinforcing rib. A rigid suction pipe is spirally wound around the outer side of the mud transfer cylinder. One end of the rigid suction pipe is located inside the inner cavity of the mud transfer cylinder, and the other end is fixedly connected to an extension head. A drive motor is located on one side of the mud transfer cylinder, and a circulation pump is located on the other side. A discharge pipe is fixedly connected to the discharge end of the circulation pump. A guide assembly is located on the outer side of the rigid suction pipe. Two support legs are fixedly connected to the outer sides of both the first and second fixed rings.

[0006] Preferably, multiple support rods are fixedly connected to the inner sides of both the first and second fixed rings, and a rotating ring is fixedly connected to the inner sides of the multiple support rods. A connecting column is fixedly connected to the end of the mud transfer cylinder near the drive motor. The connecting column is rotatably connected to the inner side of the corresponding rotating ring, and the connecting column is fixedly connected to the output end of the drive motor. A discharge pipe is fixedly connected to the end of the mud transfer cylinder near the circulation pump. The discharge pipe is rotatably connected to the inner side of the corresponding rotating ring, and the discharge pipe is rotatably connected to the inlet end of the circulation pump.

[0007] Preferably, the guide assembly includes a lead screw, which is rotatably connected between a first fixed ring and a second fixed ring. A guide block is threadedly connected to the outer side of the lead screw, and the guide block is sleeved on the outer side of the rigid suction tube. A guide rod is slidably connected to the inner side of the guide block, and the guide rod is fixedly connected between the first fixed ring and the second fixed ring.

[0008] Preferably, a drive wheel is fixedly connected to the outer side of the output end of the drive motor, a timing belt is sleeved on the outer side of the drive wheel, a driven wheel is sleeved on the other end of the timing belt, and the driven wheel is fixedly connected to the outer side of the lead screw.

[0009] Preferably, a rotating head is fixedly connected to the feed end of the circulating pump, the rotating head is rotatably connected to the outside of the discharge pipe, and multiple connecting brackets are fixedly connected to the outside of the circulating pump, with the other end of each of the multiple connecting brackets fixedly connected to the corresponding support rod.

[0010] Preferably, the outer side of the mud transfer cylinder is provided with a locking groove, and the rigid suction pipe is located inside the locking groove.

[0011] Preferably, a mounting block is fixedly connected to the outside of the drive motor, and the mounting block is fixedly connected to the outside of the corresponding support rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This rapidly adjustable mud circulation device for pile foundation construction uses a drive motor to rotate a mud transfer cylinder. Simultaneously, a transmission structure consisting of a drive wheel, a synchronous belt, and a driven wheel drives a lead screw to rotate, causing a guide block fitted with a rigid suction pipe to move smoothly along the axial direction of the guide rod. This, combined with the rotation of the mud transfer cylinder, allows for the adjustment of the position of the rigid suction pipe and the extension head within the pile foundation hole. The device can quickly adjust the suction depth and range according to changes in mud level and concentration distribution, avoiding mud overflow due to excessively high levels or component vacuuming due to excessively low levels. This effectively overcomes the limitations of traditional fixed suction modes.

[0013] 2. This rapidly adjustable mud circulation device for pile foundation construction uses a locking groove on the outside of the mud transfer cylinder to protect the rigid suction pipe, preventing pipe deformation during adjustment. Combined with the stable support structure formed by the first fixing ring, the second fixing ring, and the reinforcing ribs, it effectively avoids the mud retention and leakage problems caused by pipe bending and pulling in traditional devices, ensuring a continuous and stable mud circulation process and achieving efficient mud recovery and reuse.

[0016] 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.

[0017] like Figure 1-5 As shown, a mud circulation device for pile foundation construction that can be quickly adjusted includes a first fixed ring 1 and a second fixed ring 2. A plurality of reinforcing ribs 3 are fixedly connected between the first fixed ring 1 and the second fixed ring 2. A mud transfer cylinder 8 is rotatably connected between the first fixed ring 1 and the second fixed ring 2 on the inner side of the plurality of reinforcing ribs 3. A rigid suction pipe 12 is spirally wound on the outer side of the mud transfer cylinder 8. One end of the rigid suction pipe 12 is located in the inner cavity of the mud transfer cylinder 8, and the other end of the rigid suction pipe 12 is fixedly connected to an extension head 13. A drive motor 6 is provided on one side of the mud transfer cylinder 8, and a circulation pump 15 is provided on the other side of the mud transfer cylinder 8. A discharge pipe 18 is fixedly connected to the discharge end of the circulation pump 15. A guide assembly is provided on the outer side of the rigid suction pipe 12. Two support legs 4 are fixedly connected to the outer sides of both the first fixed ring 1 and the second fixed ring 2.

[0018] In this embodiment, multiple support rods 10 are fixedly connected to the inner sides of the first fixed ring 1 and the second fixed ring 2. A rotating ring 9 is fixedly connected to the inner sides of the multiple support rods 10. A connecting column 7 is fixedly connected to the end of the mud transfer cylinder 8 near the drive motor 6. The connecting column 7 is rotatably connected to the inner side of the corresponding rotating ring 9, and the connecting column 7 is fixedly connected to the output end of the drive motor 6. A discharge pipe 14 is fixedly connected to the end of the mud transfer cylinder 8 near the circulation pump 15. The discharge pipe 14 is rotatably connected to the inner side of the corresponding rotating ring 9, and the discharge pipe 14 is rotatably connected to the feed end of the circulation pump 15.

[0019] Specifically, the user first securely installs the device on the external frame using the four support legs 4 on the outer sides of the first fixing ring 1 and the second fixing ring 2. Then, the user starts the drive motor 6, and the output end of the drive motor 6 drives the connecting column 7 to rotate. At the same time, the discharge pipe 14 at the other end of the mud transfer cylinder 8 is rotatably connected to the rotating ring 9, thereby achieving stable rotation of the mud transfer cylinder 8 between the first fixing ring 1 and the second fixing ring 2. The first fixing ring 1 and the second fixing ring 2 are fixedly connected by multiple reinforcing ribs 3, which effectively enhances the load-bearing strength of the overall structure.

[0020] In this embodiment, the guide assembly includes a lead screw 22, which is rotatably connected between the first fixed ring 1 and the second fixed ring 2. A guide block 24 is threadedly connected to the outer side of the lead screw 22. The guide block 24 is sleeved on the outer side of the rigid suction tube 12. A guide rod 23 is slidably connected to the inner side of the guide block 24. The guide rod 23 is fixedly connected between the first fixed ring 1 and the second fixed ring 2. A drive wheel 19 is also fixedly connected to the outer side of the output end of the drive motor 6. A synchronous belt 20 is sleeved on the outer side of the drive wheel 19. A driven wheel 21 is sleeved on the other end of the synchronous belt 20. The driven wheel 21 is fixedly connected to the outer side of the lead screw 22.

[0021] Specifically, when the drive motor 6 starts, the output end of the drive motor 6 will also drive the drive wheel 19 to rotate synchronously. The drive wheel 19 drives the driven wheel 21 to rotate through the synchronous belt 20 on the outside, thereby driving the lead screw 22 to rotate synchronously. When the lead screw 22 rotates, the guide block 24 connected to its outer thread moves smoothly along the axial direction of the lead screw 22 under the guidance of the guide rod 23 fixed between the first fixed ring 1 and the second fixed ring 2. Since the guide block 24 is sleeved on the outside of the rigid suction pipe 12, the movement of the guide block 24 drives the rigid suction pipe 12 to adjust its position synchronously along the axial direction of the mud transfer cylinder 8. At the same time, in coordination with the rotation of the mud transfer cylinder 8, the extension head 13 fixed at the end of the rigid suction pipe 12 away from the mud transfer cylinder 8 can be quickly adjusted to the mud suction position required for pile foundation construction, meeting the mud suction requirements of different depths and ranges. When the extension head 13 reaches the designated position, the mud enters the rigid suction pipe 12 through the extension head 13 and is transported along the rigid suction pipe 12 to the inner cavity of the mud transfer cylinder 8. Subsequently, the mud in the mud transfer cylinder 8 is transported to the feed end of the circulating pump 15 through the discharge pipe 14.

[0022] In this embodiment, a rotating head 16 is fixedly connected to the feed end of the circulating pump 15. The rotating head 16 is rotatably connected to the outside of the discharge pipe 14. Multiple connecting brackets 17 are fixedly connected to the outside of the circulating pump 15. The other end of each of the multiple connecting brackets 17 is fixedly connected to a corresponding support rod 10.

[0023] Specifically, the rotating head 16 fixed at the feed end of the circulating pump 15 is rotatably connected to the outside of the discharge pipe 14, ensuring the continuity of mud transportation when the discharge pipe 14 rotates with the mud rotating drum 8. After the circulating pump 15 is started, it pressurizes the mud input at the feed end and then discharges the mud to the designated position through the discharge pipe 18 fixedly connected at its discharge end, completing the efficient circulation operation of mud during the pile foundation construction process and realizing the rapid recycling and reuse of mud.

[0024] In this embodiment, a locking groove 11 is provided on the outer side of the mud transfer cylinder 8, and a rigid suction pipe 12 is provided on the inner side of the locking groove 11.

[0025] Specifically, the guide block 24 drives the rigid suction tube 12 to adjust its position axially in sync, so that the rigid suction tube 12 can be housed inside the locking groove 11. This can effectively prevent the rigid suction tubes 12 from being squeezed against each other and deformed, thus affecting the suction effect. In addition, the rigid suction tube 12 and the locking groove 11 have the same length.

[0026] In this embodiment, a mounting block 5 is fixedly connected to the outside of the drive motor 6, and the mounting block 5 is fixedly connected to the outside of the corresponding support rod 10.

[0027] Specifically, the design of mounting block 5 can improve the stability of drive motor 6 during operation. It is worth noting that drive motor 6 in this solution is a device that can be purchased on the market by those skilled in the art. The device has not been structurally modified in this paper. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it skillfully. Thus, this paper will not elaborate on it in detail. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposal of the processing circuit in this paper is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electronic control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0028] It should be noted that this utility model is a mud circulation device for pile foundation construction that can be quickly adjusted. The user first uses the four support legs 4 on the outside of the first fixed ring 1 and the second fixed ring 2 to stably install it on the external equipment frame. Then, the user starts the drive motor 6. The output end of the drive motor 6 drives the connecting column 7 to rotate. At the same time, the discharge pipe 14 at the other end of the mud transfer cylinder 8 is rotatably connected to the rotating ring 9 fixed by the support rod 10 on the inside of the second fixed ring 2. This achieves stable rotation of the mud transfer cylinder 8 between the first fixed ring 1 and the second fixed ring 2. The first fixed ring 1 and the second fixed ring 2 are fixedly connected by multiple reinforcing ribs 3, which effectively enhances the load-bearing strength of the overall structure. When the drive motor 6 starts, the output end of the drive motor 6 also drives the drive wheel 19 to rotate synchronously. The drive wheel 19 drives the driven wheel 21 to rotate through the synchronous belt 20 on the outside, thereby driving the lead screw 22 to rotate synchronously. When the lead screw 22 rotates, the guide block 24, which is threaded on its outer side, moves smoothly along the axial direction of the lead screw 22 under the guidance of the guide rod 23 fixed between the first fixed ring 1 and the second fixed ring 2. Since the guide block 24 is sleeved on the outside of the rigid suction pipe 12, the movement of the guide block 24 drives the rigid suction pipe 12 to adjust its position synchronously along the axial direction of the mud transfer cylinder 8. At the same time, in coordination with the rotation of the mud transfer cylinder 8, the extension head 13 fixed away from the end of the rigid suction pipe 12 can be quickly adjusted to the mud suction position required for pile foundation construction, meeting the mud suction needs of different depths and ranges. Moreover, by driving the rigid suction pipe 12 to adjust its position synchronously along the axial direction through the guide block 24, it can effectively prevent the rigid suction pipes 12 from being squeezed together. Deformation of the expansion head 12 affects the suction effect. When the expansion head 13 reaches the designated position, the mud enters the rigid suction pipe 12 through the expansion head 13 and is transported along the rigid suction pipe 12 to the inner cavity of the mud transfer cylinder 8. Subsequently, the mud in the mud transfer cylinder 8 is transported to the feed end of the circulation pump 15 through the discharge pipe 14. The rotating head 16 fixed at the feed end of the circulation pump 15 is rotatably connected to the outside of the discharge pipe 14, ensuring the continuity of mud transport when the discharge pipe 14 rotates with the mud transfer cylinder 8. Finally, after the circulation pump 15 starts, it pressurizes the mud input at the feed end and discharges the mud to the designated position through the discharge pipe 18 fixedly connected at its discharge end. This completes the efficient circulation operation of mud during pile foundation construction, realizing the rapid recovery and reuse of mud, which is quite practical.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
