Description

Technical Field

[0001] This invention belongs to the field of concrete construction technology, and specifically relates to a concrete pumping device for preventing blockage. Background Technology

[0002] Concrete, an engineering composite material carefully bonded together with various aggregates by cementitious materials, plays a vital role in modern construction. In the implementation of large-scale engineering projects, in order to ensure that concrete can be poured quickly and accurately to the designated location to meet complex and ever-changing construction needs, concrete pumping technology has emerged. Concrete pumping devices are indispensable mechanical equipment on construction sites. With their efficient and stable performance, they greatly simplify the long-distance transportation process of concrete. Through concrete pumping devices, concrete can be easily pumped from the mixing plant or temporary storage point to the construction area tens or even hundreds of meters away, greatly reducing the heavy burden of manual handling and significantly improving the work efficiency of the construction team.

[0003] Chinese patent CN221143589U discloses a concrete pump anti-clogging device. This invention uses a drive mechanism to move a pusher plate and push large sand and gravel particles on the grating plate, pushing the sand and gravel to one side of the grating plate, making it easier to push the sand and gravel off the grating plate. However, the core design of this anti-clogging device is to use the grating plate to intercept large sand and gravel particles in the concrete. Although this mechanism is effective, its limitation is that the spacing of the grating plate is preset and fixed, lacking the ability to be flexibly adjusted according to the actual application scenario. This fixed spacing setting is often difficult to accurately match diverse usage needs, especially when dealing with concrete with different particle size distributions or special compositions, thus limiting its wide application and high efficiency.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) The present invention has an interception mechanism at the top of the feed hopper. The driver drives the positive and negative screws to rotate, so that the two adjustment frames drive the adjustment frame to unfold, and the several moving rods drive several grid plates to unfold as well. This allows the spacing of several grid plates to be flexibly adjusted according to the actual application scenario, so as to accurately match the diverse usage requirements, thereby enhancing the interception effect of the grid plates on large sand and gravel particles in concrete, and also enhancing the anti-clogging effect of the concrete pumping device.

[0021] (2) The present invention provides a cleaning mechanism at the top of the interception mechanism. When the spacing of several grid plates is adjusted, several fixed plates move accordingly to adjust the spacing. Then, the elastic force of the spring applies a pushing force to the cleaning frame so that the cleaning frame is located exactly in the middle of two adjacent grid plates. This design allows the cleaning frame to be adjusted along with the grid plates. Then, the drive motor drives the reciprocating screw to rotate, thereby driving several cleaning frames to move back and forth to clean the large sand and gravel particles intercepted by the grid plates.

[0022] (3) The present invention has a mixing mechanism inside the temporary storage tank. The mixing motor drives the drive shaft to rotate, which can drive several mixing paddles and cleaning frames to rotate together. It can clean the inner wall of the temporary storage tank while fully mixing and stirring the concrete. The synchronous transmission of the synchronous belt drives the conveying blade to rotate, so that the concrete can be mixed and fed into the discharge pipe at the same time, thereby improving the uniformity and fluidity of the concrete and avoiding the phenomenon of concrete clogging the pipe.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] Please see Figures 1 to 8 As shown, an anti-clogging concrete pumping device includes:

[0038] Feed hopper 1, with a temporary storage tank 5 installed at the bottom of feed hopper 1, and a mixing mechanism 6 installed inside the temporary storage tank 5;

[0039] The interception mechanism 2 includes an adjustment box 21, a guide groove 22, a moving rod 23, a grid plate 24, a flow guide frame 25, and a reinforcing plate 26. There are two adjustment boxes 21, two guide grooves 22, and two flow guide frames 25. The two adjustment boxes 21 are respectively installed on the outer walls of the two sides of the feed hopper 1. The two guide grooves 22 are respectively opened on the inner sides of the two adjustment boxes 21. There are several moving rods 23, several grid plates 24, and several reinforcing plates 26. Several moving rods 23 are respectively slidably connected to the corresponding guide grooves 22. Several grid plates 24 are respectively installed on the inner side of several moving rods 23. The two flow guide frames 25 are respectively installed on the outer walls of the two outermost grid plates 24. Several reinforcing plates 26 are respectively installed on the inner walls of the two flow guide frames 25. The two adjustment boxes 21 are each equipped with an adjustment component.

[0040] Cleaning mechanism 3 is installed on top of interception mechanism 2 and can clean up large particles of sand and gravel inside interception mechanism 2.

[0041] Depend on Figures 1 to 4It can be seen that guide frames 4 are installed on both sides of the outer wall of the interception mechanism 2, two support frames 7 are installed on the outer surface of the temporary storage tank 5, and the tops of the two support frames 7 are installed on the outer wall of the feed hopper 1. A control panel 8 is installed on the outer wall of the feed hopper 1. A discharge pipe 9 is installed at one end of the temporary storage tank 5, and a conveying pump 10 is installed at the other end of the discharge pipe 9. A conveying pipe 11 is installed at the other end of the conveying pump 10.

[0042] The adjustment assembly includes an adjustment frame 27, a fixing block 28, a driver 29, a positive and negative screw 210, and an adjustment frame 211. The adjustment frame 27 is installed on the outer end of several moving rods 23. There are two fixing blocks 28 and two adjustment frames 211. The two fixing blocks 28 are installed on the inner wall of the adjustment box 21. The driver 29 is installed on the outer wall of one of the fixing blocks 28. The positive and negative screw 210 is installed between the opposite surfaces of the two fixing blocks 28 through bearings. The two adjustment frames 211 are installed on the outer surface of the positive and negative screw 210.

[0043] As can be seen from the above, by controlling the start of the driver 29 through the control panel 8, the positive and negative screws 210 drive the two adjusting frames 211 on them to move outward, thereby driving the two middle moving rods 23 to move outward as well, which in turn drives the adjusting frame 27 to unfold. The unfolded adjusting frame 27 drives the several moving rods 23 on it to unfold as well. And by the sliding limit of the several moving rods 23 in the guide groove 22, the several moving rods 23 can drive the several grid plates 24 to unfold stably together, thereby adjusting the distance between the several grid plates 24. This allows the several grid plates 24 to flexibly adjust the spacing according to the actual application scenario, and can accurately match diverse usage needs. Especially when dealing with concrete with different particle size distributions or special components, it can enhance the interception effect of several grid plates 24 on large sand and gravel particles in concrete, improve its wide application and high efficiency performance, and thus avoid the situation of large sand and gravel particles clogging the device, and also improve the smoothness of concrete pumping.

[0044] For details, please refer to Figures 1 to 4 As shown, the adjustment frame 27 is a diamond-shaped telescopic frame, the driver 29 is electrically connected to the control panel 8, the two adjustment frames 211 are rectangular frames, and the two adjustment frames 211 are connected to the two middle moving rods 23. The flow guide frame 25 is an L-shaped structure, and the top surface of the flow guide frame 25 is an inclined surface.

[0045] As can be seen from the above, by extending and retracting the rhomboid adjustment frame 27, the spacing of several moving rods 23 can be adjusted to achieve the spacing adjustment of multiple grid plates 24. The rectangular adjustment frame 211 does not need to contact the adjustment frame 27 and does not affect the retraction or unfolding of the adjustment frame 27. The guide frame 25 with the top surface set as an inclined surface can play a guiding role for concrete.

[0046] Example 2:

[0047] refer to Figure 5 and Figure 6 As shown, the cleaning mechanism 3 includes a cleaning rod 31, a reciprocating screw 32, a support block 33, a protective cover 34, and a drive motor 35. There are two reciprocating screws 32, two protective covers 34, and two drive motors 35. The two reciprocating screws 32 are installed on the outer surface of the cleaning rod 31. There are four support blocks 33, and the four support blocks 33 are respectively installed at both ends of the two reciprocating screws 32. The two protective covers 34 are respectively installed between the opposite faces of two adjacent support blocks 33. The two drive motors 35 are respectively installed at one end of the two reciprocating screws 32.

[0048] The outer surface of the cleaning rod 31 is equipped with several fixed plates 36 and several cleaning frames 37 that are distributed in an alternating manner. A protective sleeve 38 is provided between the opposite face of the cleaning frame 37 and the adjacent fixed plate 36, and a spring 39 is provided inside each of the protective sleeves 38.

[0049] As can be seen from the above, when the spacing of several grid plates 24 is adjusted, several fixed plates 36 connected to them will move synchronously and automatically adjust the distance between them. At this time, the elastic force of the spring 39 can apply a pushing force to the cleaning frame 37, so that the cleaning frame 37 is exactly in the middle of two adjacent fixed plates 36 and also in the middle of two adjacent grid plates 24. This design ensures that the cleaning frame 37 can automatically adjust with the adjustment of the spacing of the grid plates 24, so as to always maintain the position between two adjacent grid plates 24. Then, the control panel 8 controls the drive motor 35 to start, so that the reciprocating screw 32 drives the cleaning rod 31 to move back and forth, thereby driving several fixed plates 36 and several cleaning frames 37 to move back and forth as well, so that the cleaning frame 37 cleans the large sand and gravel particles intercepted by the grid plates 24.

[0050] Preferred, Reference Figure 5 and Figure 6 As shown, the cleaning frame 37 is configured as a Y-shaped structure, and the top surface of the cleaning frame 37 is flush with the top surface of the regulating box 21. The protective sleeve 38 is configured as a folded rubber sleeve. The top surface of the cleaning rod 31 is lower than the bottom surface of the protective cover 34, and its bottom surface is higher than the top surface of the guide frame 25. The drive motor 35 is electrically connected to the control panel 8.

[0051] As can be seen from the above, the bottom ends of several middle fixing plates 36 are set in a U-shape, and the bottom ends of the two outermost fixing plates 36 are set in an L-shape, so that several fixing plates 36 can automatically adjust as the grid plate 24 moves. The Y-shaped cleaning frame 37 is convenient for pushing and intercepting large sand and gravel particles. The folded rubber protective sleeve 38 can be folded up or unfolded as the spacing is adjusted, and it can also protect the spring 39, so that the cleaning rod 31 does not contact the protective cover 34 or the guide frame 25.

[0052] Example 3:

[0053] refer to Figure 7 and Figure 8 As shown, the mixing mechanism 6 includes a mixing motor 61, a drive shaft 62, a mixing paddle 63, a connecting block 64, a wall cleaning frame 65, and a protective box 66. The mixing motor 61 is located at the other end of the temporary storage tank 5. The drive shaft 62 is installed at the output end of the mixing motor 61, and both ends of the drive shaft 62 are respectively installed on the inner walls of the two sides of the temporary storage tank 5 through bearings. Several mixing paddles 63 and several connecting blocks 64 are provided, and several mixing paddles 63 are installed on the outer surface of the drive shaft 62. Several connecting blocks 64 are respectively installed at the bottom ends of several mixing paddles 63. The wall cleaning frame 65 is installed at the bottom ends of several connecting blocks 64. The protective box 66 is installed on the outer surface of the drive shaft 62 through bearings.

[0054] A conveyor shaft 67 is mounted on the lower part of the outer wall of the protective box 66 via a bearing. A conveyor blade 68 is mounted on the outer surface of the conveyor shaft 67. Pulleys 69 are mounted on the outer surfaces of both the conveyor shaft 67 and the drive shaft 62. A synchronous belt 610 is mounted between the outer surfaces of the two pulleys 69. A support rod 611 is mounted in the middle of the outer wall of the protective box 66, and the other end of the support rod 611 is mounted on the inner wall of the temporary storage tank 5.

[0055] As can be seen from the above, when the concrete with large sand and gravel particles intercepted enters the temporary storage tank 5 through the feed hopper 1, the control panel 8 controls the start of the mixing motor 61, causing the drive shaft 62 to drive several mixing paddles 63 and pulleys 69 to rotate together. This allows the mixing paddles 63 to fully mix and stir the concrete in the temporary storage tank 5, and also causes several connecting blocks 64 to drive the wall cleaning frame 65 to rotate, cleaning the concrete adhering to the inner wall of the temporary storage tank 5. Then, through the synchronous transmission of the synchronous belts 610 installed on the two pulleys 69, the conveying shaft 67 drives the conveying blades 68 to rotate, so that the concrete can be fed into the discharge pipe 9 while being mixed. This improves the uniformity and fluidity of the concrete, avoids the phenomenon of concrete segregation, and also avoids the phenomenon of concrete clogging the pipe. This allows the concrete to be pumped smoothly in the conveying pipe 11, ensuring the construction progress and avoiding damage to the conveying pump 10.

[0056] Preferred, Reference Figure 7 and Figure 8 As shown, the two pulleys 69 and the synchronous belt 610 are all located inside the protective box 66. The bottom surface of the protective box 66 is higher than the bottom surface of the connecting block 64. The cleaning frame 65 is set with an L-shaped structure, and the outer wall of the cleaning frame 65 is in contact with the inner wall of the temporary storage tank 5. The mixing motor 61 is electrically connected to the control panel 8.

[0057] As can be seen from the above, the protective box 66 can protect the two pulleys 69 and the synchronous belt 610, so that the protective box 66 does not affect the rotation of the wall cleaning frame 65, which is conducive to the wall cleaning frame 65 cleaning the inner wall of the temporary storage tank 5.

[0058] Application example:

[0059] This design is applicable to various complex construction environments with high requirements for concrete delivery, such as the construction of high-rise buildings, bridges and overpasses, roads and water conservancy projects, and mines and tunnels. This design, through the installation of an interception mechanism 2, uses adjustable spacing of several grating plates 24 to intercept and separate large sand and gravel particles from the concrete. This design effectively prevents large sand and gravel particles from clogging the pipeline during pumping, improving pumping smoothness and construction efficiency. Furthermore, the cleaning mechanism 3 cleans up the large sand and gravel particles intercepted by the interception mechanism 2, ensuring the continuous and effective operation of the interception mechanism 2 and avoiding pumping interruptions due to blockages. Finally, the mixing mechanism 6 stirs and mixes the concrete, improving its uniformity and fluidity. This design helps reduce stratification and segregation during concrete delivery, improving pumpability and construction quality.
