Description

Technical Field

[0001] The invention relates to the field of concrete pouring, and more particularly to an anti-segregation conduit device for omnidirectional concrete feeding. Background Art

[0002] The concrete feeding duct is a tubular device used to transport concrete during concrete construction to ensure that it can be accurately and evenly fed and prevent segregation and other problems. It is usually used in situations where concrete needs to be transported vertically or horizontally, such as the pouring of high-rise buildings, elevated structures, underground foundations, etc.

[0003] When using the feeding pipe to feed concrete, if the mix ratio of concrete is not appropriate, the fluidity of concrete will be affected. If the viscosity of concrete is high (such as high viscosity of cement paste or coarse aggregate), heavy coarse aggregate may be deposited at the bottom of the pipe or stratified when entering the pipe during vertical transportation. Especially when the fluidity of concrete is poor, concrete may form blockage or stagnation in the pipe. Summary of the invention

[0013] Furthermore, the lower end of the spiral sleeve is integrally formed with an annular extension portion 1 inserted into the annular groove 1, and the lower end of the annular extension portion 1 is fixedly connected with a plurality of inclined top blocks matching the inclined groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present solution is provided with an anti-blocking component, which drives the inner tube body in the outer tube body to rotate through the driving part. During the rotation of the inner tube body, the concrete in the inner tube body is slightly stirred through the arc-shaped flange and the shallow serrated flange on the inner wall. This stirring action helps to break the stratification between the cement slurry and the coarse aggregate and prevent the coarse aggregate from being deposited in the pipeline. Especially when the fluidity of the concrete is poor, the rotation of the inner liner can promote the uniform flow of concrete, reduce deposition, make the flow rate of the concrete in the pipeline more uniform, reduce the accumulation and deposition caused by uneven flow rate, and further reduce the risk of blockage.

[0020] (2) This scheme is provided with an anti-blocking and sedimentation reduction unit. During the rotation of the hollow rotating part, the spiral sleeve can also be driven to rotate. The cooperation between the inclined top block at the bottom of the spiral sleeve and the inclined groove enables the spiral sleeve to move up and down outside the second column. Its spiral structure will produce a screw-like effect on the concrete, which can further enhance the mixing and pushing effect of the concrete, making the flow of the concrete in the conduit smoother. Especially for relatively dry or viscous concrete, the spiral blades can effectively overcome the internal friction of the concrete, push the concrete downward, reduce the possibility of blockage, prevent concrete from being retained in the pipeline, and ensure the continuity of material discharge.

[0021] (3) The present solution is provided with a plurality of micro-vibration motors inside the column. The micro-vibration motors can help reduce the adhesion of cement slurry and coarse aggregate in concrete and reduce internal friction by generating tiny vibrations in the inner tube body. Such vibrations can improve the fluidity of concrete, especially for concrete with high viscosity or poor fluidity. Vibration can help it flow better and avoid blockage caused by insufficient fluidity. Vibration can continuously disturb the concrete to maintain its fluidity and reduce blockage caused by solidification or curing. It can also enhance the up and down movement of the spiral sleeve and the rotation of the inner liner, thereby helping to clear the accumulated materials in the pipeline.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 13 , an anti-segregation conduit device for omni-directional concrete feeding, comprising an outer tube body 1, an annular flange 11 is provided on the outer wall of the outer tube body 1, and two hanging rings 12 are symmetrically fixed to the outer wall of the outer tube body 1. An anti-blocking component 3 is also connected to the interior of the outer tube body 1, and a driving part 2 for driving the anti-blocking component 3 to rotate is connected to the outer wall of the outer tube body 1;

[0039] The anti-blocking assembly 3 includes a hollow rotating part 34 rotatably connected to the inner wall of the outer tube body 1, a tooth key 341 provided on the outer surface of the hollow rotating part 34 and matched with the driving part 2, an inner tube assembly rotatably connected to the inner part of the outer tube body 1 and connected to the lower end of the hollow rotating part 34, and a hollow limiting seat 33 fixed to the lower end of the outer tube body 1, wherein the upper end of the hollow limiting seat 33 is fitted with the lower end of the inner tube assembly, and the inner tube assembly rotates synchronously with the hollow rotating part 34 and disturbs the concrete to avoid concrete blockage;

[0040] The driving part 2 includes a motor 23 and a fixing plate 22 fixedly connected to the outer wall of the outer tube body 1, and a gear 24 rotatably connected to one side of the fixing plate 22, and the output shaft of the motor 23 is fixedly connected to the gear 24, the gear 24 passes through the inside of the outer tube body 1 and meshes with the tooth key 341, and a cover body 21 is fixedly connected to one side of the fixing plate 22, and the cover body 21 is arranged outside the motor 23.

[0041] The inner tube assembly includes an inner tube body 31 rotatably connected to the inside of the outer tube body 1, a plurality of columns 35 movably inserted into the inside of the inner tube body 31, a plurality of arc-shaped flanges 36 opened on the inner wall of the inner tube body 31, a connecting portion 32 rotatably connected to the inside of the outer tube body 1 and fixedly connected to the lower end of the inner tube body 31, and one end of the plurality of columns 35 is fixedly connected to the lower end of the hollow rotating portion 34.

[0042] A plurality of shallow sawtooth-shaped flanges 37 are evenly arranged in an annular array on the inner wall of the inner tube body 31 , and the plurality of shallow sawtooth-shaped flanges 37 are all located below the plurality of arc-shaped flanges 36 .

[0043] By adopting the above technical solution, the motor 23 drives the gear 24 to rotate, the gear 24 rotates and drives the hollow rotating part 34 to rotate through the tooth key 341, the hollow rotating part 34 rotates and drives the inner tube 31 to rotate inside the outer tube 1 through multiple columns 35, when the inner tube 31 rotates, multiple arc flanges 36 and multiple shallow sawtooth flanges 37 on the inner wall of the inner tube 31 rotate with the inner tube 31, and the inner tube 31 rotates during the rotation of the inner tube 31 through the arc flange 36 on its inner wall (the arc flange itself does not produce too much stirring effect, but it can slightly help to evenly mix the concrete by increasing the contact area, especially in the process of vertical flow, which has an effect on the uniformity of cement slurry and coarse aggregate The inner tube body 31 is slightly stirred by the shallow serrated flange 37 (the shallow serrated design can moderately stir the concrete, which helps to reduce the deposition of coarse aggregate and the separation of cement slurry and aggregate, while having little effect on fluidity. It will not produce excessive resistance or distort the flow path) and the shallow serrated flange 37 (the shallow serrated design can moderately stir the concrete, which helps to reduce the deposition of coarse aggregate and the separation of cement slurry and aggregate, while having little effect on fluidity. It will not produce excessive resistance or distort the flow path) and the concrete in the inner tube body 31 is slightly stirred. This stirring action helps to break the stratification between the cement slurry and the coarse aggregate and prevent the deposition of coarse aggregate in the pipeline. Especially when the fluidity of the concrete is poor, the rotation of the inner liner can promote the uniform flow of concrete, reduce deposition, make the flow rate of concrete in the pipeline more uniform, reduce the accumulation and deposition caused by uneven flow rate, and further reduce the risk of blockage.

[0044] like Figure 3 , Figure 4 , Figure 6-Figure 9 As shown, the inner tube body 31 is also connected to an anti-blocking and precipitation reduction unit 4, and the anti-blocking and precipitation reduction unit 4 includes a frame body 41 fixedly connected to the inner wall of the inner tube body 31, a frame body 2 fixedly connected to the inner wall of the hollow limit seat 33, a column body 2 43 whose two ends are respectively connected to the frame body 1 41 and the frame body 2, and a spiral sleeve body 44 movably sleeved on the outside of the column body 2 43.

[0045] The interior of the frame body 2 is provided with a positioning groove 331 and an annular groove 1 332 , and the inner wall of the annular groove is provided with a plurality of inclined grooves 333 . One end of the column body 2 43 is fixedly connected to the lower end of the frame body 1 41 , and the other end of the column body 2 43 is inserted into the positioning groove 331 .

[0046] The lower end of the spiral sleeve 44 is integrally formed with an annular extension portion 441 that is inserted into the annular groove 332, and the lower end of the annular extension portion 441 is fixedly connected with a plurality of inclined top blocks 442 that match the inclined groove 333. The inclined top blocks 442 are moved out of the inclined groove 333 through the inclined surface and push the spiral sleeve 44 to move upward outside the column 43. The interior of the frame 41 is also connected to an elastic portion 42 for applying pressure to the upper end of the spiral sleeve 44 to force the spiral sleeve 44 to move downward outside the column 43 and reset.

[0047] An annular groove 411 is formed at the lower end of the frame body 41, and an annular extension part 443 inserted into the annular groove 411 is integrally formed at the upper end of the spiral sleeve body 44. The elastic part 42 includes a ring body 421 fixedly connected to the inner wall of the annular groove 411, a spring 422 fixedly connected to the lower end of the ring body 421, a ring body 423 fixedly connected to the other end of the spring 422 and located inside the annular groove 411, and a plurality of ball bearings rotatably connected to the lower end of the ring body 423. The upper end of the annular extension part 443 is in contact with the plurality of ball bearings.

[0048] By adopting the above technical scheme, when the hollow rotating part 34 rotates to drive the inner tube body 31 to rotate, the inner tube body 31 rotates to drive the frame body 1 41, the column body 2 43 and the spiral sleeve body 44 to rotate. The rotation of the spiral sleeve body 44 can stir the concrete at the center of the inner tube body 31. At the same time, when the spiral sleeve body 44 rotates, the inclined top block 442 at the bottom of the spiral sleeve body 44 can move out of the inclined groove 333, and the inclined top block 442 pushes the spiral sleeve body 44 upward. The annular extension part 2 443 at the top of the spiral sleeve body 44 can apply a force to the ring body 2 423 and cause the spring 422 to contract. When the spiral sleeve body 44 rotates and drives the inclined top block 442 to rotate so that the inclined top block 442 moves back to the top of the inclined groove 333, the spring 422 is retracted. The spring 422 generates a force to push the annular extension part 443 and the spiral sleeve 44 downward, so that the inclined top block 442 re-enters the inclined groove 333. The spiral structure of the spiral sleeve 44 cooperates with the up and down movement to produce an effect similar to that of a screw pusher on the concrete, which can further enhance the mixing and pushing effect of the concrete, making the flow of the concrete in the inner tube body 31 smoother, ensuring that the concrete will not segregate and deposit, especially for relatively dry or viscous concrete, the spiral blades can effectively overcome the internal friction of the concrete, push the concrete to flow downward, reduce the possibility of blockage, prevent concrete from being retained in the pipeline, and ensure the continuity of material discharge. The up and down movement of the spiral sleeve 44 can also continuously stir the concrete.

[0049] like Fig.10 and Fig.11As shown, a conductive slip ring stator 5 is fixedly connected inside the outer tube body 1, and the terminal of the conductive slip ring stator 5 passes through the outer tube body 1 and extends outward, a conductive slip ring rotor 6 is fixedly connected inside the hollow rotating part 34, and the conductive slip ring rotor 6 is rotationally connected to the conductive slip ring stator 5, and multiple micro vibration motors 8 and a single wiring part 7 are fixedly connected inside the multiple columns 35, and the multiple micro vibration motors 8 are linearly connected to the wiring part 7, and one end of the wiring part 7 passes through the hollow rotating part 34 and is connected to the conductive slip ring stator 5.

[0050] By adopting the above technical solution, the connection terminal of the conductive slip ring stator 5 is externally connected to the power line, and the conductive slip ring stator 5 transmits electric energy to the connection part 7 through the conductive slip ring rotor 6. The connection part 7 is a circuit board (circuit board control is a mature existing technology and will not be repeated here). A plurality of interfaces are arranged on the circuit board, and the plurality of interfaces are respectively connected to a plurality of micro vibration motors 8 through a plurality of wires. The plurality of micro vibration motors 8 generate tiny vibrations in the column 35, and the vibrations are transmitted to the inner tube body 31 through the column 35. The vibrations can help reduce the adhesion of cement slurry and coarse aggregate in the concrete and reduce the internal friction. Such vibrations can improve the fluidity of the concrete, especially for concrete with high viscosity or poor fluidity. The vibrations can help it flow better and avoid blockages caused by insufficient fluidity. The vibrations can continuously disturb the concrete and maintain its fluidity, reduce blockages caused by solidification or coagulation, and can also enhance the up and down movement of the spiral sleeve and the rotation of the inner liner, thereby helping to clear the accumulated materials in the pipeline.

[0051] like Figure 5 and Fig.12 As shown, the inner wall of the outer tube body 1 is also fixedly connected with a heating sleeve 9, and the heating sleeve 9 is sleeved on the outside of the inner tube body 31, the inner wall of the heating sleeve 9 is in rotational contact with the outer wall of the inner tube body 31, and the terminal of the heating sleeve 9 passes through the outer tube body 1 and extends outward, and the interior of the column 2 43 is fixedly connected with a columnar heating part 10, and the columnar heating part 10 is linearly connected to the conductive slip ring stator 5.

[0052] By adopting the above technical solution, the heating sleeve 9 can generate heat and heat the inner tube body 31 after being energized. The heating sleeve 9 can adopt a heating sleeve, which is a common component used for external heating and is usually made of metal or alloy materials. The interior can transfer heat through electric heating belts, steam, hot oil, etc. as needed. It belongs to mature existing technology and will not be repeated here. The heat acts on the concrete in the inner tube body 31 through the inner tube body 31. The columnar heating part 10 can adopt an electric heating rod (which belongs to mature existing technology and will not be repeated here). The power cord of the columnar heating part 10 passes through the inside of the frame 41 and is connected to the conductive slip ring rotor 6 in the hollow rotating part 34. The heat generated by the columnar heating part 10 can act on the concrete through the rotating sleeve 44. By heating the concrete, the viscosity of the concrete can be reduced, the fluidity of the concrete can be improved, the flow of the concrete in the pipeline can be smoother, and the risk of blockage can be reduced. At the same time, the temperature of the concrete in the conduit can be effectively maintained to prevent the cement hydration product from quickly solidifying on the pipe wall due to the low temperature. Especially in low temperature environment, cement is easy to solidify into hard blocks, resulting in clogging of the conduit. By heating, the fluidity of concrete can be maintained, the solidification of concrete in the pipeline can be reduced, and smooth transportation can be ensured. In addition, the heated spiral casing 44 can help the cement slurry and coarse aggregate to be better mixed through temperature differences during movement, thereby reducing stratification.

[0053] Usage: insert the outer tube body 1 between the stirrups in the middle of the frame column section, the bottom of the outer tube body 1 is less than 2m away from the bottom surface of the frame column, the lifting ring 12 on the upper part of the outer wall of the outer tube body 1 is reliably fixed by wire rope, steel skeleton and tower crane rope, the annular flange 11 on the outer wall of the outer tube body 1 is connected with the rubber hose through a pipe clamp, and the concrete enters the outer tube body 1 through the rubber hose. The driving part 2 drives the inner tube body 31 to rotate inside the outer tube body 1. During the rotation of the inner tube body 31, the concrete in the inner tube body 31 is slightly stirred through the arc flange 36 and the shallow serrated flange 37 on its inner wall. When the hollow rotating part 34 rotates to drive the inner tube body 31 to rotate, the rotation of the inner tube body 31 drives the frame body 1 41, the column body 2 43 and the spiral sleeve body 44 to rotate, and the spiral sleeve body The rotation of the spiral sleeve 44 can stir the concrete at the center of the inner tube body 31. At the same time, during the rotation of the spiral sleeve 44, the spiral sleeve 44 can also move up and down. The spiral structure of the spiral sleeve 44 cooperates with the up and down movement to produce a screw-like pushing effect on the concrete, which can further enhance the mixing and pushing effect of the concrete, making the flow of concrete in the inner tube body 31 smoother. Multiple micro-vibration motors 8 generate tiny vibrations in the column 35, and the vibrations are transmitted to the inner tube body 31 through the column 35, thereby enhancing the up and down movement of the spiral sleeve and the rotation of the inner liner pipe, helping to clear the accumulated materials in the pipeline. Through the above treatment, the concrete can flow smoothly in the outer tube body 1 and the inner tube body 31, and be discharged from the bottom of the outer tube body 1.

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
