Description

Technical Field

[0001] This application relates to the field of concrete pouring equipment technology, and in particular to a stabilizing device and a concrete filling method for filling concrete into the cavity of a pipe wall. Background Technology

[0002] Currently, when pouring concrete into the interlayer of a double-walled steel pipe, the centrifugal force and gravity of the steel pipe as it rotates after being erected are used to fill the concrete. However, because the steel pipe is very tall after being erected, generally exceeding 10 meters, if the steel pipe cannot be stably controlled when it is rotating rapidly, an accident of the steel pipe tipping over may occur.

[0003] Generally, when casting the aforementioned steel pipes, a steel frame is used to install support components above the middle of the steel pipe. For example, three or more rollers can be installed around the steel pipe to support it. However, after the rollers come into contact with the pipe body, they may damage the surface of the pipe body under high-speed movement. Furthermore, different diameter pipe bodies require different diameter tooling to ensure that the rollers can always be in contact with the pipe body, which further increases the cost. Summary of the Invention

[0004] Therefore, it is necessary to provide a stabilizing device for concrete filling in the cavity of a pipe wall, which addresses the problem that the pipe cannot be effectively stabilized when concrete is injected after it is set on a rotating platform, and that the rollers currently used to stabilize the pipe are prone to causing damage to the surface of the pipe.

[0005] The first aspect of this application provides a stabilizing device for filling concrete into a cavity within a pipe wall, used to stabilize a pipe fitting on a rotating platform, wherein the pipe fitting has an inner pipe and an outer pipe, and a cavity for filling concrete is formed between the inner pipe and the outer pipe; the stabilizing device includes:

The telescopic member is adapted to drive the abutment member to move synchronously towards the inner tube until the abutment member abuts against the wall of the inner tube, so as to straighten and stabilize the tube in a set position.

[0009] In one embodiment, the pipe fitting further includes a spiral web disposed within the cavity and connecting the inner pipe and the outer pipe, and the cavity is divided by the spiral web to form a plurality of interconnected receiving cavities.

[0010] In one embodiment, the rotation center of the rotating platform is coaxial with the pipe fitting.

[0011] In one embodiment, the material conveying assembly includes a material conveying main pipe, which is partially disposed within the pipe fitting. The material conveying main pipe is coaxially arranged with the pipe fitting, and a blocking plate is provided inside the material conveying main pipe. The blocking plate is used to separate the material conveying main pipe to form a material conveying cavity and a mounting cavity for installing the stabilizing assembly.

[0012] In one embodiment, the conveying assembly further includes a hopper and a conveying branch pipe, wherein the narrow end of the hopper is connected to the conveying cavity of the conveying main pipe for conveying concrete into the conveying cavity; the inlet end of the conveying branch pipe is connected to the conveying cavity, and the outlet end of the conveying branch pipe is connected to the cavity.

[0013] In one embodiment, the stabilizing component further includes a plurality of sliders disposed on the wall of the main conveying pipe, and a plurality of telescopic members are provided, the first ends of the plurality of telescopic members being respectively connected to the corresponding plurality of sliders, and each slider being able to drive the corresponding telescopic member to move axially along the wall of the main conveying pipe.

[0014] In one embodiment, the stabilizing component further includes a drive member and a slide bar, the slide bar being connected to multiple sliders simultaneously, the output end of the drive member being connected to the slide bar, the drive member being adapted to drive the slide bar to move axially, and to drive multiple sliders to move synchronously via the slide bar.

[0015] In one embodiment, the abutment is an arc-shaped structural member, and the arc of the arc-shaped structural member is the same as the arc of the inner tube wall.

[0016] In one embodiment, the fixing assembly includes a cantilever, a bearing, a sleeve, and a guide rail. The bearing is fitted onto the main conveying pipe, and the sleeve is fitted onto the bearing. A first end of the cantilever is connected to the sleeve via a connector, and a second end of the cantilever is connected to the guide rail, which extends vertically along the pipe. The cantilever is capable of moving along the guide rail and lifting the main conveying pipe to a set position.

[0017] In one embodiment, the stabilizing device further includes a positioning guide disposed on the rotating platform, the center of the positioning guide being adapted to coincide with the axis of the rotating platform and the pipe; and / or,

[0018] The positioning guide extends axially in a direction away from the rotating platform, and its outer diameter gradually decreases to form a frustum shape, with the maximum outer diameter of the positioning guide being smaller than the inner diameter of the pipe fitting; and / or,

[0019] The positioning guide includes at least two positioning guide sections, which are adapted to be spaced apart to form a segmented structure.

[0020] The second aspect of this application provides a concrete filling method, applied to the stabilizing device for concrete filling in the pipe wall cavity described in the first aspect of this application, the concrete filling method comprising:

[0021] Raise the material conveying assembly to a set position;

[0022] Place the pipe fitting on the rotating platform;

[0023] The material conveying assembly is lowered, and the stabilizing component provided on the material conveying assembly abuts against the inner tube of the pipe fitting, thereby stabilizing the pipe fitting on the rotating platform;

[0024] The discharge end of the material conveying assembly is connected to the cavity of the pipe fitting;

[0025] The rotating platform is driven to rotate, and material is simultaneously fed into the cavity via the material conveying assembly until the cavity is filled.

[0026] In the aforementioned stabilizing device for filling concrete into the cavity of the pipe wall, there is a cavity for filling concrete between the inner and outer pipes of the pipe fitting. The pipe fitting is mounted on a rotating platform, which drives the pipe fitting to rotate. While rotating, concrete is filled into the cavity of the pipe fitting through a conveying assembly. When the conveying assembly outputs concrete, it is first fixed in a set position by a fixing assembly to ensure that the conveying assembly will not move during the concrete pouring process. A stabilizing assembly is also provided on the conveying assembly. The first end of the telescopic member of the stabilizing assembly is connected to the conveying assembly, and the second end of the telescopic member can extend and retract towards the inner pipe of the pipe fitting. The second end of the telescopic member is provided with an abutment that is adapted to the inner pipe wall. The abutment can move synchronously with the telescopic member until it abuts against the inner pipe wall of the pipe fitting. Thus, through the coordinated movement of the telescopic member and the abutment, the stabilizing assembly can adapt to pipe fittings of different sizes and specifications.

[0027] In addition, since the material conveying component is fixed in the set position by the fixing component, the material conveying component will not change position, and consequently the position of the stabilizing component set on the material conveying component will not change. When the telescopic component of the stabilizing component drives the abutting component to extend and abut against the inner tube, the stabilizing component can play a role in stabilizing and correcting the position of the pipe to ensure that the pipe can always be stable in the set position on the rotating platform.

[0028] Furthermore, the abutment is adapted to the wall of the inner tube, so that the abutment in contact with the inner tube will not cause damage to the inner tube during the process of the tube rotating and feeding material into it. Attached Figure Description

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] like Figure 1 As shown, this application provides a stabilizing device for filling concrete into a cavity in a pipe wall. The stabilizing device is used to stabilize the pipe 10 on a rotating platform 20. The pipe 10 has an inner pipe 11 and an outer pipe 12, and a cavity 13 for filling concrete is formed between the inner pipe 11 and the outer pipe 12. When filling concrete into the cavity 13, the rotating platform 20 rotates synchronously so that the concrete filled into the cavity 13 gradually fills the entire cavity 13 under the action of centrifugal force and gravity.

[0041] The stabilizing device includes a conveying assembly 30, a fixing assembly 40, and a stabilizing assembly 50. The inlet end of the conveying assembly 30 is used to input concrete, and the outlet end of the conveying assembly 30 communicates with the cavity 13 for outputting concrete into the cavity 13. The fixing assembly 40 is connected to the conveying assembly 30 to fix the conveying assembly 30 in a set position. The stabilizing assembly 50 includes a telescopic member 51 and an abutment member 52 adapted to fit the wall of the inner pipe 11. The first end of the telescopic member 51 is connected to the conveying assembly 30, and the second end of the telescopic member 51 is connected to the abutment member 52. The telescopic member 51 is adapted to drive the abutment member 52 to move synchronously towards the inner pipe 11 until the abutment member 52 abuts against the wall of the inner pipe 11, thereby straightening and stabilizing the pipe 10 in a set position.

[0042] Specifically, the pipe fitting 10 also includes a spiral web 14, which is spirally disposed within the cavity 13 and connects both the inner pipe 11 and the outer pipe 12 of the pipe fitting 10. Furthermore, the spiral web 14 within the cavity 13 divides the cavity 13 into multiple interconnected cavities. Concrete can be filled into each cavity under the action of centrifugal force and gravity. The rotating platform 20 drives the pipe fitting 10 to rotate, further ensuring that the concrete fills each cavity along the spiral web 14 during the filling process, reducing the occurrence of voids after the concrete in each cavity has solidified.

[0043] More specifically, to ensure that the pipe fitting 10 is not thrown off when rotating on the rotating platform 20, the rotation center of the rotating platform 20 is set to be coaxial with the central axis of the pipe fitting 10. At the same time, the central axis of the pipe fitting 10 is perpendicular to the horizontal line.

[0044] like Figure 1 As shown, the material conveying assembly 30 includes a main material conveying pipe 31, which is partially disposed within the fitting 10 and is coaxially arranged with the fitting 10. A blocking plate 34 is provided within the internal cavity of the main material conveying pipe 31. The blocking plate 34 separates the internal cavity of the main material conveying pipe 31 to form a conveying cavity 35 and an installation cavity 36. Concrete is suitable for flowing within the conveying cavity 35. When the concrete flows to the blocking plate 34, the blocking plate 34 restricts further flow of the concrete into the installation cavity 36. The installation cavity 36 is used to install the stabilizing assembly 50.

[0045] Specifically, the conveying assembly 30 also includes a hopper 33 and a conveying branch pipe 32. The hopper 33 has a narrow end and a wide end. The narrow end of the hopper 33 is connected to the conveying chamber 35. Concrete can flow into the hopper 33 from the wide end and be fed into the conveying chamber 35 through the narrow end connected to the conveying chamber 35. In addition, the inlet end of the conveying branch pipe 32 is connected to the main conveying pipe 31. Specifically, the inlet end of the conveying branch pipe 32 is connected to the conveying chamber 35 of the main conveying pipe 31. That is, after the concrete flows into the conveying chamber 35, the concrete can flow into the conveying branch pipe 32 from the conveying chamber 35. The outlet end of the conveying branch pipe 32 is connected to the cavity 13. The concrete flowing into the conveying branch pipe 32 finally flows into the cavity 13 formed by the inner pipe 11 and the outer pipe 12 of the pipe fitting 10 to fill the cavity 13 of the pipe fitting 10 with concrete.

[0046] In this embodiment, the material conveying branch pipe 32 can be configured as an arc-shaped pipe fitting 10, and the number of material conveying branch pipes 32 can be one or more. Furthermore, the interface between the outlet end of the material conveying branch pipe 32 and the cavity 13 of the pipe fitting 10 is connected and fixed via a grouting joint 37.

[0047] like Figure 1As shown, the stabilizing component 50 also includes multiple sliders 53, which are disposed on the wall of the main conveying pipe 31. Multiple telescopic members 51 are also provided, each corresponding to one of the sliders 53. Specifically, the first end of each telescopic member 51 is disposed on a corresponding slider 53, and the second end of each telescopic member 51 is connected to the same abutment member 52. Each slider 53 can drive the telescopic member 51 connected to it to move synchronously along the axial direction of the wall of the main conveying pipe 31, and adjust the abutment position between the abutment member 52 and the inner tube 11 of the pipe fitting 10.

[0048] Specifically, the telescopic component 51 can be implemented using telescopic arms, which can be V-shaped and have at least three arms, each extending to the same length. Additionally, the abutment component 52 can be an arc-shaped structure with the same curvature as the inner tube 11 wall, thus ensuring that the abutment component 52 does not damage the tube wall during contact with the tube wall or during subsequent rotation of the tube 10.

[0049] When the telescopic arm drives the abutment member 52 to extend and retract, multiple telescopic arms can extend and retract synchronously to ensure that the abutment members 52 connected to each telescopic arm can retract or extend synchronously. At the same time, by using the telescopic arm to drive the abutment member 52 to extend and retract, it can adapt to pipe fittings 10 of different sizes and specifications. Furthermore, the extension and retraction of the stabilizing component 50 can straighten and fix pipe fittings 10 of different sizes and specifications, ensuring that the pipe fittings 10 will not tip over or shift in position during the rotating material conveying process, while also ensuring the stability of the pipe fittings 10 placed on the rotating platform 20.

[0050] More specifically, the stabilizing component 50 also includes a drive element 54 and a slide rod 55, which is connected to multiple sliders 53. In this embodiment, the drive element 54 can be a hydraulic cylinder to provide the driving force. The extended end of the hydraulic cylinder is connected to the slide rod 55, so that when the hydraulic cylinder performs work, it can drive the slide rod 55 to extend and retract synchronously. In addition, the slide rod 55 is connected to multiple sliders 53, that is, when one slider 53 moves axially along the conveying main pipe 31, it can drive the other sliders 53 to move axially synchronously through the slide rod 55, thereby realizing the coordinated movement between the sliders 53 and ensuring the consistency of the position when the abutment 52 abuts against the inner tube 11 of the pipe fitting 10.

[0051] like Figure 1As shown, the fixing assembly 40 includes a cantilever 42, a bearing 43, a sleeve, and a guide rail 41. The guide rail 41 is mounted on the tower 45 and extends vertically along the tower 45. The bearing 43 is fitted onto the main conveying pipe 31, and the sleeve 44 is fitted onto the bearing 43. The first end of the cantilever 42 is connected to the sleeve 44 via a connector, and the second end of the cantilever 42 is connected to the guide rail 41. At least two sets of cantilever 42 are provided horizontally, and these at least two sets of cantilever 42 form a certain angle in the horizontal direction. Therefore, each cantilever 42 can move along the guide rail 41 to adjust its position. Meanwhile, when adjusting the position of the cantilever 42, since the cantilever 42 is connected to the sleeve 44, and the sleeve 44 is connected to the conveying main pipe 31 via the bearing 43, the cantilever 42 will drive the conveying main pipe 31 and other structural components connected to the conveying main pipe 31 to move synchronously while adjusting the position of the cantilever 42, so as to achieve the height adjustment of the conveying main pipe 31 and its structural components.

[0052] Therefore, through the stabilizing device for filling the cavity 13 of the pipe wall with concrete, when outputting concrete into the cavity 13 of the pipe fitting 10, the conveying component 30 is first fixed in a set position by the fixing component 40 to ensure that the conveying component 30 will not move during the concrete pouring process. Furthermore, a stabilizing component 50 is provided on the conveying component 30. The first end of the telescopic component 51 of the stabilizing component 50 is connected to the conveying component 30, and the second end of the telescopic component 51 can extend and retract towards the inner pipe 11 of the pipe fitting 10. The second end of the telescopic component 51 is provided with an abutment 52 that is adapted to the wall of the inner pipe 11. The abutment 52 can move synchronously with the telescopic component 51 until it abuts against the wall of the inner pipe 11 of the pipe fitting 10. Thus, through the coordinated movement of the telescopic component 51 and the abutment 52, the stabilizing component 50 can adapt to pipe fittings 10 of different sizes and specifications.

[0053] In addition, since the material conveying component 30 is fixed in the set position by the fixing component 40, the material conveying component 30 will not change position, and the position of the stabilizing component 50 set on the material conveying component 30 will not change. When the telescopic component 51 of the stabilizing component 50 drives the abutting component 52 to extend and abut against the inner tube 11, the stabilizing component 50 can play a role in stabilizing and correcting the position of the pipe 10, so as to ensure that the pipe 10 can always be stable in the set position on the rotating platform 20.

[0054] Furthermore, the abutment 52 is adapted to the wall of the inner tube 11, so that the abutment 52, which is in contact with the inner tube 11, will not cause damage to the inner tube 11 during the process of the tube 10 rotating and feeding material into it.

[0055] like Figure 1As shown, in this embodiment, the stabilizing device further includes a positioning guide 60, which is detachably mounted on the rotating platform 20. The central axis of the positioning guide 60 coincides with the axis of the rotating platform 20 and the axis of the tube 10. Furthermore, the positioning guide 60 extends axially in a direction away from the rotating platform 20, so that its outer diameter gradually decreases and forms a frustum-shaped structure. The maximum outer diameter of the positioning guide 60 is smaller than the inner diameter of the tube 10, wherein the maximum outer diameter of the positioning guide 60 is the diameter of the portion of the positioning guide 60 closest to the rotating platform 20. It should be noted that the outer diameter of the positioning guide 60 is set to circular here, but it can also be set to an elliptical or other shapes according to user requirements.

[0056] Furthermore, the positioning guide 60 includes at least two positioning guide segments, which are adapted to be spaced apart to form a segmented structure. Thus, the combination of the at least two positioning guide segments can form a frustum-shaped structure with spaced areas.

[0057] Therefore, by setting the positioning guide 60, the tube 10 can be placed on the rotating platform 20 to guide the placement of the tube 10, so as to ensure that the tube 10 can be quickly placed in the set position of the rotating platform 20; at the same time, the positioning guide 60 can also correct the shape of the tube 10 by the outer periphery of the positioning guide 60 when the tube 10 is placed on the rotating platform 20, so that the contact part between the tube 10 and the positioning guide 60 forms a standard circle.

[0058] This application provides a concrete filling method, which is applied to the stabilizing device for filling concrete in the cavity of the pipe wall as described in any of the above embodiments. The concrete filling method includes: raising the material conveying assembly 30 to a set position; placing the pipe 10 on the rotating platform 20; lowering the material conveying assembly 30 and making the stabilizing component 50 provided on the material conveying assembly 30 abut against the inner pipe 11 of the pipe 10 to stabilize the pipe 10 on the rotating platform 20; connecting the discharge end of the material conveying assembly 30 to the cavity 13 of the pipe 10; driving the rotating platform 20 to rotate, and simultaneously conveying material into the cavity 13 through the material conveying assembly 30 until the cavity 13 is filled.

[0059] Therefore, during concrete filling, the conveying assembly 30 is first raised to its highest point using the fixing component 40, and then the pipe fitting 10 is hoisted onto the rotating platform 20 using a crane, making the pipe fitting 10 vertical and fixed on the rotating platform 20. Simultaneously, the plane of the rotating platform 20 is parallel to the horizontal line, and the central axis of the pipe fitting 10 placed on the rotating platform 20 coincides with the rotation center. Then, the conveying assembly 30 is lowered so that the main conveying pipe 31 of the conveying assembly 30 is inserted into the pipe fitting 10. At this time, the stabilizing component 50 installed on the part of the main conveying pipe 31 inserted into the pipe fitting 10 is also inserted into the pipe fitting 10, and the central axis of the main conveying pipe 31 also coincides with the rotation center of the rotating platform 20 and the central axis of the pipe fitting 10. Subsequently, the telescopic component 51 of the stabilizing component 50 extends, and at the same time, the telescopic component 51 drives the abutment component 52 to move towards the inner tube 11 until the abutment component 52 abuts against the inner tube 11. If the pipe fitting 10 is in an offset state at this time, the abutment component 52 can gradually straighten and stabilize the pipe fitting 10 after abutting against the inner tube 11. Then, the material conveying branch pipe 32 connected to the material conveying main pipe 31 is connected to the interface of the pipe fitting 10. Then, the rotating platform 20 is started to rotate, and concrete is injected into the cavity 13 of the pipe fitting 10 through the material conveying component 30. Under the action of centrifugal force, gravity and vibration, the entire cavity 13 is gradually filled.
