Description

Technical Field

[0001] This utility model belongs to the field of floating mud extraction technology, specifically relating to a device for extracting floating mud from a caisson. Background Technology

[0002] Caisson sludge refers to the soil and mud accumulated during caisson construction. This sludge creates resistance during the caisson's sinking, affecting its sinking speed and stability. If not removed in time, it can lead to difficulties in sinking, or even cause the caisson to tilt or fail to sink. Therefore, removing caisson sludge is one of the important measures to ensure the smooth progress of caisson construction.

[0003] A related technology (publication number CN214833367U) discloses a sludge extraction and discharge device. The device uses a negative pressure pump to create a vacuum in the negative pressure tank, and then sucks the sludge into the negative pressure tank through a suction pipe. The sludge then enters a mud-water separator through a discharge pipe to separate the sludge into water and soil for easy treatment. This eliminates the need for workers to re-enter the sewer, ensuring worker safety and saving costs. The device also includes an adjustment device to adjust the working angle and position of the suction pipe, resulting in cleaner and more thorough sludge extraction.

[0004] The existing sludge extraction devices for caissons lack support in their flexible extraction pipes, which are prone to bending, narrowing the extraction channel and reducing extraction efficiency. This results in extracting the same amount of sludge taking longer, which can severely impact project progress and increase construction costs for large-scale caisson construction projects. Furthermore, pipe bending leads to unstable extraction pressure, and narrowing of the pipe creates localized increased resistance, resulting in uneven pressure distribution. This not only affects extraction performance but also shortens the lifespan of the equipment. Utility Model Content

[0005] To address the shortcomings of existing caisson sludge extraction devices, such as the lack of support in the flexible extraction pipes, which easily bends and narrows the extraction channel, leading to reduced extraction efficiency and requiring more time to extract the same amount of sludge, this invention provides a caisson sludge extraction device. This device uses a first and second limiting ring to support the pipe, preventing bending during extraction and ensuring the extraction channel remains narrow, thus guaranteeing efficient extraction, saving overall operation time, ensuring the progress of caisson sludge treatment, and maintaining a smooth, curved pipe shape to prevent bending during use. This also ensures uniform pressure distribution during extraction, thus guaranteeing extraction effectiveness and extending the equipment's lifespan. The specific technical solution is as follows:

[0006] A device for extracting floating mud from a caisson includes an extraction machine body. One end of the extraction machine body is connected to a connecting part on its left side, and the other end of the connecting part is connected to a pipe. The pipe forms a smooth arc-shaped channel on the left side of the extraction machine body through a support unit.

[0007] The support unit includes a connecting rod fixedly installed on the left side wall of the extraction machine body, and a support column fixedly installed on the left end of the connecting rod. A fixing plate is fixedly installed on the upper left end of the support column. A first sleeve and a second sleeve are respectively installed on the two free ends of the fixing plate. A first moving arm is slidably provided through the inner cavity of the first sleeve. A first limiting ring is fixedly installed at the top end of the first moving arm. A second moving arm is slidably provided through the inner cavity of the second sleeve. A second limiting ring is fixedly installed at the left end of the second moving arm.

[0008] The first limiting ring and the second limiting ring are configured as hollow rings.

[0009] In the above technical solution, the second movable arm and the first movable arm are arranged perpendicularly to each other, the second movable arm is provided with a recess, and the position of the recess corresponds to that of the first movable arm.

[0010] In the above technical solution, a first fixing pin is fixedly installed at the bottom end of the first moving arm, a second fixing pin is fixedly installed at the right end of the second moving arm, a housing is fixedly installed at the lower right end of the support column, and a driving component for driving the first fixing pin and the second fixing pin to move synchronously is provided at the housing.

[0011] In the above technical solution, the drive assembly includes a cylinder installed in the housing, and a drive block installed at the output end of the cylinder. Drive rods are fixedly installed at both ends of the drive block, and the two drive rods are arranged perpendicular to each other. A sliding groove is provided through the drive rod.

[0012] The first fixing pin and the second fixing pin are respectively slidably embedded in the inner cavity of the groove at the corresponding position.

[0013] In the above technical solution, the bottom drive rod is arranged parallel to the second movable arm, and the top drive rod is arranged parallel to the first movable arm.

[0014] In the above technical solution, the side wall of the fixing plate is vertical and fixedly installed with a fixing arm, and a third limiting ring is installed at the free end of the fixing arm. The third limiting ring is a hollow ring.

[0015] The second limiting ring, the third limiting ring, and the first limiting ring form a support channel for supporting the pipeline.

[0016] In the above technical solution, there are two connecting rods, and multiple first reinforcing rods are vertically installed between the two connecting rods.

[0017] In the above technical solution, a second reinforcing rod is installed at an angle between the support column and the fixing plate.

[0018] The beneficial effects of this utility model's sludge extraction device compared to existing technologies are as follows:

[0019] I. Existing sludge extraction devices for caissons lack support in their extraction pipes, leading to easy bending and narrowing of the extraction channel, resulting in reduced extraction efficiency and requiring more time to extract the same amount of sludge. For large-scale caisson construction projects, this reduced efficiency can severely impact project progress and increase construction costs. This invention addresses this issue by using a first and second limiting ring to support the pipe, preventing bending during extraction and ensuring the extraction channel remains narrow, thus guaranteeing efficient sludge extraction, saving overall operation time, and ensuring the progress of caisson sludge treatment.

[0020] Second, in response to the problem that existing pipe bends can lead to unstable extraction pressure and increased local resistance at pipe narrowing points, resulting in uneven pressure distribution, which not only affects the extraction effect but also the service life of the equipment, this utility model uses a first limiting ring, a second limiting ring, and a third limiting ring to ensure that the pipe is in a smooth arc shape, avoids bending during use, and ensures uniform pressure distribution when the pipe is extracting floating sludge, thereby ensuring the extraction effect and the service life of the equipment.

[0021] Third, this utility model can adjust the extension length of the first moving arm and the second moving arm through the cylinder, the drive block, the drive rod and the slide groove, so as to adjust the position of the first limiting ring and the second limiting ring, so as to flexibly meet the support and positioning requirements of the pipeline in different positions. Compared with the fixed support method, it is more flexible and adaptable, and the support position of the pipeline can be flexibly adjusted and locked.

[0022] Fourth, by setting a recessed part, this utility model can avoid interference between the second and first moving arms while driving the second and first moving arms to move synchronously with the same power, making the design more reasonable.

[0023] In summary, this utility model supports the pipeline through the first and second limiting rings, preventing the pipeline from bending during extraction and narrowing the extraction channel, which would affect the efficiency of sludge extraction. This ensures the normal progress of sludge extraction, saves overall operation time, guarantees the construction progress of sludge treatment in the well, and ensures that the pipeline has a smooth arc shape to avoid bending during use. It also ensures uniform pressure distribution when extracting sludge, thereby guaranteeing the extraction effect and the service life of the equipment. In addition, the positions of the first and second limiting rings can be adjusted to flexibly meet the support and positioning requirements of the pipeline at different locations, making it more flexible and adaptable than fixed support methods.

[0028] The following are specific implementation cases and appendices. Figures 1 to 3 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0029] Main references Figures 1 to 3 As shown, a sludge extraction device for a caisson includes an extraction machine body 1. One end of the extraction machine body 1 is connected to a connecting part 2 on the left side, and the other end of the connecting part 2 is connected to a pipe 3. By opening the extraction machine body 1, the sludge from the caisson can enter the cavity of the extraction machine body 1 through the pipe 3 and the connecting part 2 for processing, thereby realizing the extraction of sludge. The pipe 3 forms a smooth arc-shaped channel on the left side of the extraction machine body 1 through a support unit to ensure that the sludge enters the extraction machine body 1 for processing without obstruction along the smooth channel.

[0030] Main references Figure 1 and Figure 2As shown, the support unit includes a connecting rod 4 fixedly installed on the left side wall of the extraction machine body 1, and a support column 5 fixedly installed on the left end of the connecting rod 4. A fixing plate 6 is fixedly installed on the upper left end of the support column 5. A first sleeve 7 and a second sleeve 8 are respectively installed on the two free ends of the fixing plate 6. The fixing plate 6 can support the installation of the first sleeve 7 and the second sleeve 8, and the support column 5 forms a stable connection between the fixing plate 6 and the extraction machine body 1. A first movable arm 9 is slidably provided through the inner cavity of the first sleeve 7, and the top end of the first movable arm 9 is fixed. A first limiting ring 10 is fixedly installed, and a second moving arm 12 is slidably installed through the inner cavity of the second sleeve 8. A second limiting ring 14 is fixedly installed at the left end of the second moving arm 12. The first limiting ring 10 and the second limiting ring 14 are hollow rings. The pipe 3 is installed through the inner cavities of the second limiting ring 14 and the first limiting ring 10. The pipe 3 can be supported by the two points of the second limiting ring 14 and the first limiting ring 10, so as to avoid the pipe 3 bending during the sludge extraction process, which would affect the extraction pressure and working efficiency.

[0031] For details, please refer to the main references. Figure 1 and Figure 2 As shown, the second moving arm 12 and the first moving arm 9 are arranged perpendicularly to each other. The second moving arm 12 is provided with a recess 13, and the position of the recess 13 corresponds to that of the first moving arm 9, so as to ensure that the second moving arm 12 and the first moving arm 9 remain perpendicular to each other after they move, thereby ensuring that the second limiting ring 14 and the first limiting ring 10 can move relative to each other by the same distance.

[0032] Main references Figure 3As shown, a first fixing pin 11 is fixedly installed at the bottom end of the first moving arm 9, a second fixing pin 15 is fixedly installed at the right end of the second moving arm 12, and a housing 16 is fixedly installed at the lower right end of the support column 5. A drive assembly for driving the first fixing pin 11 and the second fixing pin 15 to move synchronously is provided at the housing 16. The drive assembly drives the first fixing pin 11 and the second fixing pin 15 to move synchronously, so as to realize the synchronous movement of the second moving arm 12 and the first moving arm 9, and finally realize the synchronous movement of the second limiting ring 14 and the first limiting ring 10. The drive assembly includes a cylinder 17 installed in the housing 16, and a drive block 18 installed at the output end of the cylinder 17. Drive rods 19 are fixedly installed at both ends of the drive block 18, and the two drive rods 19 are arranged perpendicular to each other. A sliding groove 20 is opened through the drive rods 19. Among them, the first fixing pin 11 The second fixed pin 15 is slidably embedded in the inner cavity of the corresponding groove 20. The activated cylinder 17 drives the drive block 18 to move in the tilt direction. The moving drive block 18 drives the two mutually perpendicular drive rods 19 to move synchronously, so that the second fixed pin 15 installed at the end of the second moving arm 12 and the first fixed pin 11 installed at the end of the first moving arm 9 move along the inner cavity of the corresponding groove 20, so as to drive the second moving arm 12 to move along the inner cavity of the second sleeve 8, and at the same time drive the first moving arm 9 to move along the inner cavity of the first sleeve 7. With the same driving force, the positions of the second limiting ring 14 and the first limiting ring 10 are synchronously adjusted, so that the second limiting ring 14, the third limiting ring 22, and the first limiting ring 10 form an arc bend that adapts to different pipes 3, flexibly adapting to different pipe 3 support conditions.

[0033] Main references Figure 2 As shown, the bottom drive rod 19 is arranged parallel to the second moving arm 12, and the top drive rod 19 is arranged parallel to the first moving arm 9. This ensures that when the cylinder 17 drives the drive block 18 to move at a 45-degree angle, the two drive rods 19 drive the first fixed pin 11 and the second fixed pin 15 at the corresponding positions to move by the same distance, so as to ensure that the first limiting ring 10 and the second limiting ring 14 can move perpendicularly and equidistantly to each other.

[0034] In addition, the main references Figure 2 As shown, a fixed arm 21 is vertically mounted on the side wall of the fixed plate 6. A third limiting ring 22 is installed at the free end of the fixed arm 21. The third limiting ring 22 is a hollow ring. The second limiting ring 14, the third limiting ring 22 and the first limiting ring 10 form a support channel for supporting the pipe 3. The pipe 3 can be stably supported through this channel. Compared with the two-point support of the second limiting ring 14 and the first limiting ring 10, the three-point support of the second limiting ring 14, the third limiting ring 22 and the first limiting ring 10 can make the curvature of the pipe 3 smoother and ensure that the sludge extraction channel is smoother and more unobstructed.

[0035] Main references Figure 2 and Figure 3 As shown, there are two connecting rods 4, and multiple first reinforcing rods 23 are vertically installed between the two connecting rods 4. The two connecting rods 4 can further increase the stability of the connection between the support column 5 and the extraction machine body 1, and the multiple first reinforcing rods 23 can achieve a reinforced connection between the two connecting rods 4.

[0036] Main references Figure 3 As shown, a second reinforcing rod 24 is installed at an angle between the support column 5 and the fixing plate 6 to further increase the stable connection between the fixing plate 6 and the support column 5.

[0037] It is worth noting that the cylinder 17 used in this application is a commonly used self-locking cylinder on the market, whose output end can stay at any position and be locked; the main body 1 of the extraction machine is an existing device, which can realize the function of extracting floating mud from the well; the existing components mentioned above will not be described in detail here.

[0038] The working principle of the sludge extraction device for caissons in this embodiment is as follows:

[0039] Before using the equipment, pipe 3 is sequentially passed through the second limiting ring 14, the third limiting ring 22, and the first limiting ring 10. Then, pipe 3 is connected to the main body of the extraction machine 1 through the connecting part 2. The second limiting ring 14, the third limiting ring 22, and the first limiting ring 10 support pipe 3, ensuring that pipe 3 has a smooth arc shape and avoiding local bending and narrowing of pipe 3, which would affect the extraction of floating mud. The floating mud in the caisson is extracted by opening the extraction machine main body 1. The floating mud enters pipe 3 through pipe 3 for processing.

[0040] When the main body 1 of the extraction machine or the pipe 3 is replaced with different models according to different construction conditions, the degree or height of bending of the pipe 3 is different. Therefore, it is necessary to adjust the support point of the pipe 3: the cylinder 17 is opened to drive the drive block 18 to move in the tilt direction. The moving drive block 18 drives the two mutually perpendicular drive rods 19 to move synchronously, so as to cause the second fixed pin 15 installed at the end of the second moving arm 12 and the first fixed pin 11 installed at the end of the first moving arm 9 to move along the inner cavity of the corresponding slide groove 20, so as to drive the second moving arm 12 to move along the inner cavity of the second sleeve 8, and at the same time cause the first moving arm 9 to move along the inner cavity of the first sleeve 7, so as to use the same driving force to synchronously adjust the position of the second limiting ring 14 and the first limiting ring 10, so as to cause the second limiting ring 14, the third limiting ring 22, and the first limiting ring 10 to form an arc bend that adapts to different pipes 3, and flexibly adapts to the support of pipes 3 in different situations.

[0041] This utility model supports the pipe 3 through the first limiting ring 10 and the second limiting ring 14, avoiding the problem of the pipe 3 bending during the extraction process, which would narrow the extraction channel and affect the efficiency of sludge extraction. It can ensure the normal progress of sludge extraction, save overall operation time, ensure the construction progress of sludge treatment in the well, and ensure that the pipe 3 is in a smooth arc shape to avoid bending during use. It also ensures that the pressure distribution of the pipe 3 is uniform when extracting sludge, thereby ensuring the extraction effect and the service life of the equipment. In addition, the positions of the first limiting ring 10 and the second limiting ring 14 can be adjusted to flexibly meet the support and positioning requirements of the pipe 3 at different positions. Compared with the fixed support method, it is more flexible and has strong adaptability.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
