Description

Technical Field

[0001] The utility model relates to the technical field of grouting devices, in particular to an anti-blocking device for a concrete conveying pipeline. Background Art

[0002] Concrete pipe transportation is an efficient method of transporting concrete in construction. It relies on concrete pumps to power the mixed concrete, transporting it to the pouring site through specialized pipes. Pipes can be made of steel, rubber, or plastic, with different materials suitable for different scenarios. They include straight, curved, and tapered pipes to accommodate complex construction layouts. During the transportation process, concrete properties such as slump, coarse aggregate size, and sand content must meet requirements. Slump is generally between 120mm and 180mm, coarse aggregate size is appropriately selected based on the pipe's inner diameter, and the sand content is maintained at 35% to 45%. Pumping pressure is also controlled based on factors such as pipe length and the number of bends. Pipeline layout should also be rational, minimizing bends and preventing air accumulation to ensure smooth concrete delivery. This method of transportation improves construction efficiency, ensures concrete quality, and is adaptable to various construction environments.

[0003] However, blockage in concrete delivery pipelines is a possible problem. Clogged pipelines may need to be dismantled, cleaned, and reinstalled, which is a cumbersome process, delaying construction time and wasting materials. Therefore, prevention is key. In terms of concrete mix ratio, optimize the slump, sand ratio, and aggregate particle size to ensure good fluidity and workability of the concrete. In pipeline installation and layout, reduce the number of bends, avoid "U"-shaped layouts, and ensure that the pipeline connections are tight and have appropriate slopes. Of course, even so, pipeline blockages are still inevitable. When the blockage is not serious, reverse pumping is a common method. By changing the pumping direction, the concrete at the blockage is loosened. The operation should be carried out slowly and carefully observed. However, sometimes the effect is not obvious. For this reason, it is necessary to develop anti-blockage devices to prevent concrete pipeline transportation. Utility Model Content

[0004] In view of the above shortcomings, the utility model provides a device for preventing blockage in concrete pipeline transportation, which can prevent the problem of blockage of concrete during pipeline transportation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] In a preferred anti-blocking device for concrete conveying pipelines, the outer shell body is further provided with second heat dissipation holes, and there are a plurality of second heat dissipation holes evenly distributed on both sides of the outer shell body.

[0011] In a preferred anti-clogging device for a concrete delivery pipeline, the mounting plate includes a mounting plate body and a first heat dissipation hole, and the first heat dissipation hole is provided in the middle of the mounting plate body.

[0012] In a preferred anti-blocking device for a concrete conveying pipeline, the pipe clamp includes a connecting piece, a clamp and an adjusting bolt. The clamp includes an upper clamp and a lower clamp. The upper clamp and the lower clamp are connected together by an adjusting bolt.

[0025] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figures 1-4As shown, the present invention provides a concrete pipeline anti-clogging device designed to prevent concrete from clogging during pipeline transportation. The device is installed at locations in concrete pipelines prone to clogging, such as pipeline joints and pipe diameter changes. The device comprises a power supply, a mounting plate 1, a vibration motor 5, a pipe clamp 3, and a bracket 4. The vibration motor 5 is mounted on the mounting plate 1. This attached vibrator utilizes the centrifugal force generated by the motor's high-speed rotation to rotate the vibrator's eccentric mass. The rotation of the eccentric mass generates a periodic vibration force, which is transmitted through the vibrator's chassis to the formwork or other structure in close contact with it, thereby vibrating the concrete. Its operating principle is similar to that of a washing machine during the dehydration phase: vibration is generated by internal unbalanced rotating components and transmitted to the mounting plate 1. Multiple pipe clamps 3 are fixedly mounted on the mounting plate 1. The pipe clamps 3 are used to clamp the concrete pipeline. By clamping the pipeline, the vibration motor 5 transmits vibration to the pipeline. During the concrete pipeline transportation process, appropriate vibration helps maintain good fluidity within the pipeline. Concrete is a complex mixture. When flowing in a pipe, it may experience local blockage due to its own cohesiveness, the interaction of coarse aggregates, etc. Vibration can break this blockage, reduce the friction between concrete particles, and allow it to move forward more smoothly, just like gently shaking a half-blocked hourglass allows the sand to continue to flow. On the other hand, vibration can help remove air that may be present in the pipe. The accumulation of air in the pipe may cause quality problems such as interruption of concrete transportation or the formation of voids. The disturbance caused by vibration can prompt the air to move to the upper part or outlet of the pipe, thereby reducing the impact of air on concrete transportation and ensuring stable, continuous and high-quality transportation of concrete in the pipe. There are four brackets 4 and they are movably mounted at the four corners of the mounting plate 1. The brackets 4 are used to support the device to maintain stability in complex environments and provide stable support force to the ground to avoid affecting the function of the vibration motor 5. The vibration motor 5 is electrically connected to the power supply.

[0029] As a further technical improvement, the present invention further includes a housing 2, which is mounted on the mounting plate 1 and houses the vibration motor 5. The housing 2 can effectively protect the vibration motor 5 from complex external environmental factors, such as dust, gravel, and water vapor at the construction site, preventing these impurities from entering the interior of the vibration motor 5, thereby extending the service life of the motor. At the same time, the housing 2 can reduce the noise generated by the vibration motor 5 when it is working to a certain extent, reducing interference with the surrounding environment of the construction site. In terms of appearance, the housing 2 makes the entire device more regular and beautiful, and also adds a guarantee for the safe use of the device to prevent construction workers from directly contacting the vibration motor 5 and potential safety hazards.

[0030] As a further technical improvement, the shell 2 includes a shell body 200 and a connecting plate 201. The shell body 200 is in a regular geometric shape, and its material is made of a material with good strength and corrosion resistance, which can effectively resist external collisions and erosion. The connecting plates 201 are arranged at both ends of the shell body 200 and are fixed to the shell body 200, and the structure is stable. Precise mounting holes and matching bolts are provided on the connecting plate 201. The shell body 200 is installed on the mounting part through the connecting plate 201 and is connected by bolts. The installation process is more convenient and accurate, and the firmness of the connection between the shell body 200 and the mounting plate 1 is guaranteed, which further enhances the protection effect of the internal vibration motor 5 and improves the stability and reliability of the entire device.

[0031] As a further technical improvement, a handle 203 is also provided on the outer shell body 200, and the handle 203 is installed in the middle of the upper surface of the outer shell body 200. The handle 203 is made of tough material and has a non-slip texture on the surface, which is convenient for construction workers to grasp. In terms of shape, it is designed according to ergonomics, fits the holding posture of the human hand, and effectively reduces the burden on the hand. The handle 203 is connected to the outer shell body 200 by bolts to ensure that it will not loosen during transportation. This design greatly improves the portability of the device. Whether it is during installation, disassembly or relocation, construction workers can easily move the entire device through the handle 203, thereby improving construction efficiency.

[0032] As a further technical improvement, the housing body 200 is also provided with a plurality of second heat dissipation holes 202, which are evenly distributed on both sides of the housing body 200. The aperture size of the second heat dissipation holes 202 has been carefully designed to ensure good heat dissipation while preventing the entry of larger particles of dust or debris from the outside. They are arranged in a regular pattern, allowing the heat within the housing body 200 to be dissipated more evenly. When the vibration motor 5 generates heat during long-term operation, the hot air is discharged in a timely manner, maintaining the vibration motor 5 operating in a suitable temperature environment, thereby ensuring stable motor performance, extending its service life, and ensuring the reliable operation of the entire concrete conveying pipeline anti-blocking device.

[0033] As a further technical improvement, the mounting plate 1 includes a mounting plate body 100 and a first heat dissipation hole 101, and the first heat dissipation hole 101 is arranged in the middle of the mounting plate body. The size of the first heat dissipation hole 101 is carefully designed to ensure a good heat dissipation effect, prevent the entry of larger particles of dust or debris from the outside, and form an efficient heat dissipation channel with the second heat dissipation hole 202. Among the multiple first heat dissipation holes 101, a hole for the power cord to pass through is provided, and the power cord (not shown in the figure) is connected to the vibration motor 5 from the bottom of the mounting plate body 100. During the operation of the vibration motor 5, the heat generated by the motor can be quickly dissipated through the first heat dissipation hole 101, avoiding the influence of heat accumulation on the performance of the motor, ensuring that the vibration motor 5 works continuously and stably, and thus ensuring the effective operation of the entire anti-blocking device.

[0034] As a further technical improvement, the pipe clamp 3 includes a connector 300, a clamp 301, and an adjusting bolt 302. The clamp 301 includes an upper clamp 3012 and a lower clamp 3011. The adjusting bolt 302 is a common bolt with a nut, and there are two adjusting bolts 302. Connecting holes corresponding to the adjusting bolts 302 are provided on both sides of the upper clamp 3012 and the lower clamp 3011. The upper clamp 3012 and the lower clamp 3011 are connected via the adjusting bolts 302. Adjustment of the adjusting bolts 302 ensures that concrete delivery pipes of varying diameters can be securely clamped. There are two connectors 300, welded to either side of the upper clamp 3012. The upper clamp 3012 is welded to the mounting plate 1 via the connectors 300. This connection ensures that the pipe clamp 3 and the mounting plate 1 form a stable integral structure, ensuring that when the vibration motor 5 is operating, the pipe clamp 3 can stably transmit vibration to the delivery pipe, effectively preventing pipe blockage.

[0035] As a further technical improvement, the pipe clamp 3 is also equipped with a reinforcing rib 303, located between the two connectors 300. The rib 303 has excellent resistance to compression and deformation. It is welded to the two connectors 300 at both ends, forming a stable structure. The rib 303 effectively enhances the overall strength of the connector 300 used to connect the pipe clamp 3. When the pipe clamp 3 clamps the concrete conveying pipeline, it prevents the connector 300 from loosening or deforming, even in the face of strong pipeline vibration and high pressure. This facilitates the stable clamping of the pipeline and vibration transmission, further enhancing the reliability of the anti-blocking device.

[0036] As a further technical improvement, the bracket 4 includes a telescopic rod 400, a telescopic cylinder 401 and a support foot 402. The telescopic rod 400 is made of high-strength metal with a smooth surface. It is rotatably connected to the mounting plate 1, can be flexibly rotated, and can accurately adapt to the angle changes of the mounting plate 1. It is movably arranged inside the telescopic cylinder 401, and the two can be combined to achieve free adjustment of height. The support foot 402 is circular and has an anti-slip texture on the bottom, which can effectively increase the friction with the ground. The support foot 402 is hinged to the bottom of the telescopic cylinder 401 and can adjust the angle within a certain range to adapt to different terrains. This design allows the bracket 4 to stably support the device in complex environments, ensure the stable operation of the vibration motor 5, and prevent the anti-blocking effect from being affected by shaking.

[0037] As a further technical improvement, the four brackets 4 are staggered on the mounting plate 1. During installation, the range of motion and folding path of the brackets 4 were carefully considered, ensuring that the four brackets 4 do not interfere with each other during folding. Both retraction and expansion operations proceed smoothly. This improvement greatly enhances the device's portability and storage convenience. When transporting or not in use, the brackets 4 can be easily folded up, reducing space usage. This also prevents damage caused by collisions between the brackets 4, extending their service life.

[0038] In addition, this device can also cooperate with the pump to dredge the pipeline after the pipeline is blocked. While the pump is pumping forward and reverse, the device is placed at the blockage location to generate vibration to break the blockage state of the concrete, reduce the friction between the concrete particles, and enhance the dredging efficiency.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
