Description

Technical Field

[0001] This application relates to the field of concrete conveying technology, specifically an anti-clogging device for concrete conveying pipelines. Background Technology

[0002] Pipeline blockage is a common and challenging problem during concrete transportation. As a fluid material, concrete is prone to sedimentation or hardening inside pipelines due to various factors during transport, such as improper mix design, rough pipeline walls, fluctuating transport pressure, and numerous bends, leading to blockages. Once a blockage occurs, it not only affects construction progress and increases costs but can also damage the pipeline itself, sometimes necessitating replacement and causing significant inconvenience and losses to the project.

[0003] Chinese utility model patent CN221017778U discloses an anti-clogging mechanism for concrete conveying pipelines. It involves mounting the entire conveying pipeline on a vibrating support plate assembly, causing synchronous vibration when concrete adheres to the inner wall of the pipeline during transport, thus reducing the likelihood of blockage caused by concrete sticking. However, its vibration function typically provides uniform vibration to the entire pipeline, which can result in ineffective vibration of less prone-to-clogging areas. Prolonged vibration can lead to wear and damage to the pipeline, and the lack of targeted vibration means it cannot provide sufficient vibration intensity to areas prone to blockage, resulting in low anti-clogging efficiency.

[0004] Therefore, this application provides an anti-clogging device for concrete conveying pipelines to solve the above-mentioned problems. Utility Model Content

[0005] This application provides an anti-clogging device for concrete conveying pipelines, which aims to solve the problems mentioned in the background art, such as the lack of specificity in the vibration function of existing anti-clogging mechanisms for concrete conveying pipelines, and the fact that uniform vibration can easily lead to pipeline wear, resulting in low anti-clogging efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: an anti-clogging device for a concrete conveying pipeline, comprising a base, an annular seat fixedly installed on the base, a clamp disposed in the inner ring of the annular seat for fixing the outer side of the pipeline, and a striking structure disposed on the annular seat for striking the pipeline.

[0007] The striking structure includes a striking hammer disposed on one side of the annular seat for contacting the outside of the pipe, and a reciprocating assembly disposed on the annular seat for reciprocating movement of the striking hammer. Through the combined design of the base, annular seat, clamp, and striking structure, the striking structure can be moved to the easily clogged areas of the pipe for targeted striking. Compared with the traditional method of directly setting a vibration structure on the entire outside of the pipe, this targeted treatment method can reduce ineffective vibration to other parts, thereby reducing the risk of wear and damage to the entire pipe. It also focuses more on the most easily clogged areas of the pipe, thereby loosening or removing deposits or solidified materials in the middle of the concrete conveying pipe. At the same time, the reciprocating assembly drives the striking hammer to move back and forth. This continuous and targeted striking action can more effectively break and disperse blockages, thereby improving anti-clogging efficiency.

[0008] Preferably, to facilitate pipe fixing, the clamp includes arc-shaped clamping blocks symmetrically arranged in the inner ring of the annular seat and an electric push rod fixedly installed in the inner ring of the annular seat and fixedly connected to the two arc-shaped clamping blocks on opposite sides; the combined use of the arc-shaped clamping blocks and the electric push rod can adapt to the shape of the pipe, provide uniform clamping force, and ensure that the pipe will not move or slide during the tapping process.

[0009] Preferably, to facilitate the use of a hammer to strike the pipe for anti-clogging purposes, the reciprocating assembly includes a fixed box disposed between the annular seat and the hammer, an L-shaped bracket fixedly installed on the side of the fixed box near the hammer, a connecting shaft passing through the fixed box and the L-shaped bracket and rotatably connected to the fixed box and the L-shaped bracket, a rotary motor fixedly installed inside the fixed box and fixedly connected to the connecting shaft, a wheel fixedly connected to the end of the connecting shaft away from the rotary motor and located above the hammer, an eccentric shaft fixedly connected to the side of the wheel away from the connecting shaft, and a connecting rod disposed on the end of the eccentric shaft away from the wheel and rotatably connected at both ends to the eccentric shaft and the top of the hammer, respectively. The eccentric shaft is eccentrically positioned, and the top of the hammer passes through the end of the L-shaped bracket away from the connecting shaft and is slidably connected to the L-shaped bracket. By using a rotary motor to drive the connecting shaft and the wheel, as well as the eccentric shaft and connecting rod, the rotational motion can be converted into the reciprocating linear motion of the hammer. The structure is simple and effective, thereby achieving the anti-clogging requirement through striking.

[0010] Preferably, to further improve the anti-clogging effect, the tapping structure also includes a drive assembly disposed on the base and the annular seat and connected to the fixed box for causing the tapping hammer to move in a circular motion. By driving the tapping hammer to move in a circular motion through the drive assembly, it can be ensured that the tapping action covers the entire circumference of the pipe where blockage is likely to occur, rather than just a localized area of ​​the blockage. This comprehensive tapping method can more effectively loosen or remove deposits or solidified substances from the inner wall of the pipe, further improving the anti-clogging effect.

[0011] Preferably, to achieve the circular motion of the striking hammer, the drive assembly includes a gear ring rotatably connected inside the annular seat near the fixed box, a collar passing through the annular seat near the fixed box and fixedly connected to one side of the gear ring, a support column fixedly connected to the side of the collar away from the gear ring and fixedly connected to the side of the fixed box away from the striking hammer, a gear rotatably disposed in the base and meshing with the gear ring, a drive shaft rotatably connected in the base and fixedly connected to the gear, and a drive motor fixedly mounted on the base for driving the drive shaft to rotate. The collar is rotatably connected to the annular seat. The drive motor drives the shaft to directly drive the gear to rotate, thereby driving the gear ring and the striking hammer to perform circular motion. This design makes the entire drive assembly structure compact.

[0012] Preferably, to ensure the meshing transmission of the gear and the gear ring, the base has an opening at the position of the gear near the gear ring for the gear to pass through and move, and the annular seat has a notch at the position of the opening for the gear ring to pass through and move. The design of the opening and the notch provides the necessary movement space for the gear and the gear ring, so that they can mesh and transmit smoothly, thereby ensuring that there will be no jamming or interference between the gear and the gear ring during meshing, so that the device can work normally.

[0013] The anti-clogging device for this concrete conveying pipeline uses a combination design of a base, annular seat, clamp, and striking structure. This allows the striking structure to be moved to the areas in the pipeline that are prone to clogging for targeted striking. Compared to the traditional method of directly setting a vibration structure on the outside of the entire pipeline, this targeted approach reduces ineffective vibration to other parts, thereby reducing the risk of wear and damage to the entire pipeline. It also focuses more on the areas in the pipeline that are most prone to clogging, thus improving the anti-clogging efficiency.

[0014] The anti-clogging device for the concrete conveying pipeline drives a hammer to move back and forth via a reciprocating assembly. This continuous and targeted striking action can more effectively break and disperse blockages, thereby improving anti-clogging efficiency.

[0015] The anti-clogging device for the concrete conveying pipeline drives a hammer to move in a circular motion via a drive assembly. This ensures that the impact covers the entire circumference of the pipeline where blockages are likely to occur, rather than just the localized area where a blockage occurs. This comprehensive impact method can more effectively loosen or remove deposits or solidified material from the inner wall of the pipeline, further improving the anti-clogging effect.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0026] This embodiment provides an anti-clogging device for concrete conveying pipelines, such as... Figures 1-2As shown, the anti-blocking device includes a base 1, an annular seat 2 fixedly mounted on the base 1, a clamp 3 disposed in the inner ring of the annular seat 2 for fixing the outside of the pipe, and a striking structure 4 disposed on the annular seat 2 for striking the pipe; the striking structure 4 includes a striking hammer 41 disposed on one side of the annular seat 2 for contacting the outside of the pipe, and a reciprocating assembly 42 disposed on the annular seat 2 for reciprocating the striking hammer 41.

[0027] In use, first place the annular seat 2 on the outside of the pipe, then move the base 1 and the annular seat 2 to move the striking structure 4 to the area most prone to blockage or other areas. After moving to the determined position, the pipe in that area can be fixed by the clamp 3. Then, start the reciprocating assembly 42 to make the striking hammer 41 move back and forth to strike the pipe. The striking hammer 41 can generate vibration and impact force on the outside of the pipe. At this time, the generated vibration and impact force can directly act on the inner wall of the pipe, loosening or removing deposits or solidified substances. As the striking continues, the blockage in the pipe is gradually broken and dispersed, thereby restoring the smooth flow of the pipe and achieving anti-blockage.

[0028] Specifically, the clamp 3 includes arc-shaped clamping blocks 31 symmetrically arranged in the inner ring of the ring seat 2 and an electric push rod 32 fixedly installed in the inner ring of the ring seat 2 and fixedly connected to the two arc-shaped clamping blocks 31 on opposite sides.

[0029] When the annular seat 2 is fitted onto the outside of the pipe, and the striking structure 4 is moved to the desired area by moving the base 1 and the annular seat 2, the electric push rods 32 on both sides of the two arc-shaped clamps 31 are activated. Then, the two electric push rods 32 will synchronously drive the arc-shaped clamps 31 connected to them to move closer to the outside of the pipe. As the electric push rods 32 extend, the arc-shaped clamps 31 gradually contact the outside of the pipe and apply a certain clamping force. At this time, the extension of the electric push rods 32 is paused, and the two arc-shaped clamps 31 can firmly clamp the outside of the pipe. It can maintain the clamping state of the pipe during the process of conveying concrete. At the same time, it ensures the stability of the pipe when the striking structure 4 strikes the outside of the pipe. When it is necessary to adjust the striking position of the striking structure 4 or remove the anti-blocking device, the electric push rods 32 can be activated to drive the arc-shaped clamps 31 to move away from each other. At this time, the two arc-shaped clamps 31 gradually separate from the outside of the pipe, and the fixation of the pipe can be released.

[0030] Furthermore, the reciprocating assembly 42 includes a fixed housing 421 disposed between the annular seat 2 and the striking hammer 41, an L-shaped bracket 422 fixedly installed on the side of the fixed housing 421 near the striking hammer 41, a connecting shaft 424 passing through the fixed housing 421 and the L-shaped bracket 422 in sequence and rotatably connected to the fixed housing 421 and the L-shaped bracket 422, a rotary motor 425 fixedly installed inside the fixed housing 421 and fixedly connected to the connecting shaft 424, and a component fixedly connected to the connecting shaft 424 away from the rotary motor. The rotating wheel 423 is located at one end of the rotating motor 425 and above the hammer 41; the eccentric shaft 426 is fixedly connected to the side of the rotating wheel 423 away from the connecting shaft 424; and the connecting rod 427 is provided at the end of the eccentric shaft 426 away from the rotating wheel 423 and is rotatably connected to the top of the eccentric shaft 426 and the top of the hammer 41 respectively. The eccentric shaft 426 is eccentrically set, and the top of the hammer 41 passes through the end of the L-shaped bracket 422 away from the connecting shaft 424 and is slidably connected to the L-shaped bracket 422.

[0031] After the striking structure 4 is moved to the desired area and the pipe is fixed by the clamp 3, the rotary motor 425 can be started. At this time, the rotary motor 425 starts to rotate, driving the connecting shaft 424 and the rotating wheel 423 to rotate together. Since the eccentric shaft 426 is eccentrically set, it will reciprocate under the rotation of the rotating wheel 423. Since one end of the connecting rod 427 is rotatably connected to the eccentric shaft 426 and the other end is rotatably connected to the top of the striking hammer 41, the reciprocating oscillation of the eccentric shaft 426 will be transmitted through the connecting rod 427. The hammer 41 moves back and forth. Driven by the connecting rod 427, the hammer 41 moves back and forth on the L-shaped bracket 422. When the hammer 41 moves close to the pipe, it strikes the outside of the pipe, generating vibration and impact. These vibrations and impacts are directly transmitted to the inner wall of the pipe, loosening or removing deposits or solidified substances, thereby achieving the purpose of preventing blockage. As the rotary motor 425 continues to rotate, the eccentric shaft 426 will continuously oscillate back and forth, thereby driving the hammer 41 to move back and forth continuously and strike. Example

[0032] Unlike Example 1, as Figures 3-4 As shown, in order to further improve the anti-clogging effect, the striking structure 4 also includes a drive assembly 43 disposed on the base 1 and the annular seat 2 and connected to the fixed box 421 for making the striking hammer 41 move in a ring. By driving the striking hammer 41 to move in a ring by the drive assembly 43, it can be ensured that the striking action covers the entire circle of the pipe where it is prone to blockage, rather than just the local area of ​​the blockage. This comprehensive striking method can more effectively loosen or remove deposits or solidified substances on the inner wall of the pipe, further improving the anti-clogging effect.

[0033] Furthermore, the drive assembly 43 includes a gear ring 432 rotatably connected inside the annular seat 2 near the fixed box 421, a collar 431 passing through the annular seat 2 near the fixed box 421 and fixedly connected to the gear ring 432, a support column 436 fixedly connected to the side of the collar 431 away from the gear ring 432 and fixedly connected to the side of the fixed box 421 away from the hammer 41, a gear 433 rotatably disposed in the base 1 and meshing with the gear ring 432, a drive shaft 434 rotatably connected in the base 1 and fixedly connected to the gear 433, and a drive motor 435 fixedly mounted on the base 1 for driving the drive shaft 434 to rotate. The collar 431 is rotatably connected to the annular seat 2.

[0034] When the rotary motor 425 is started to drive the rotating wheel 423 and connecting shaft 424 to rotate, and through the connection of the eccentric shaft 426 and connecting rod 427, drives the striking hammer 41 to repeatedly strike the pipe, the drive motor 435 can be started simultaneously. At this time, the drive motor 435 starts to rotate, driving the drive shaft 434 to rotate together. Then, the rotation of the drive shaft 434 will drive the gear 433 fixedly connected to it to rotate together. Since the gear 433 meshes with the gear ring 432, the rotation of the gear 433 will drive the gear ring 432 to rotate together. Next, the rotation of the gear ring 432 will drive the fixed box 421 and the striking structure 4 to rotate synchronously through the connection between the collar 431 and the support column 436. Therefore, when the striking hammer 41 strikes the outside of the pipe, the drive component 43 will also drive the striking hammer 41 to make a circular motion, so as to ensure that the striking action covers the entire circle of the pipe where it is prone to blockage, rather than just the local area of ​​the blockage. This comprehensive striking method can more effectively loosen or remove the deposits or solidified substances on the inner wall of the pipe, further improving the anti-blockage effect.

[0035] In order to ensure the meshing transmission of gear 433 and gear ring 432, the base 1 has an opening 11 for gear 433 to pass through and move near the gear ring 432, and the ring seat 2 has a notch 21 for gear ring 432 to pass through and move near the opening 11. The design of the opening 11 and the notch 21 provides the necessary space for gear 433 and gear ring 432 to move, so that they can mesh smoothly and ensure that there will be no jamming or interference between gear 433 and gear ring 432 during meshing, so that the device can work normally and reduce the possibility of failure.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
