Description

Technical Field

[0001] The invention belongs to the technical field of concrete construction, and in particular relates to an anti-blocking concrete pumping device. Background Art

[0002] Concrete, as an engineering composite material formed by carefully combining various aggregates with 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 the complex and changing construction needs, concrete pumping technology came into being. Concrete pumping devices are indispensable mechanical equipment at 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 mixing plants or temporary storage points to construction areas tens or even hundreds of meters away, greatly reducing the heavy burden of manpower handling, and also significantly improving the work efficiency of construction teams.

[0003] In the Chinese patent with publication number CN221143589U, a concrete pump anti-blocking device is mentioned. The utility model drives the push plate to move and pushes the large sand and gravel on the grid plate through a driving mechanism, and pushes the sand and gravel to one side of the grid plate, so as to facilitate the sand and gravel to be pushed off the grid plate; however, the design core of this anti-blocking device is to use the grid plate to intercept the large sand and gravel particles in the concrete. Although this mechanism itself is effective, its limitation is that the spacing of the grid plate is preset and fixed, and lacks the ability to be flexibly adjusted according to the actual application scenario. This fixed spacing setting is often difficult to accurately match the diverse use requirements, especially when dealing with concrete with different particle size distributions or special components. It seems to be powerless, thereby limiting its wide application and high-efficiency performance. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See also Figures 1 to 8 As shown, an anti-blocking concrete pumping device comprises:

[0038] A feed hopper 1, a temporary storage tank 5 is installed at the bottom of the feed hopper 1, and a mixing mechanism 6 is arranged 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 guide frame 25 and a reinforcement plate 26. There are two adjustment boxes 21, two guide grooves 22 and two guide frames 25, and the two adjustment boxes 21 are respectively installed on the outer walls of both 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 a plurality of moving rods 23, grid plates 24 and reinforcement plates 26, and the plurality of moving rods 23 are respectively slidably connected with the corresponding guide grooves 22. The plurality of grid plates 24 are respectively installed on the inner ends of the plurality of moving rods 23. The two guide frames 25 are respectively installed on the outer walls of the two outermost grid plates 24. The plurality of reinforcement plates 26 are respectively installed on the inner walls of the two guide frames 25. The interiors of the two adjustment boxes 21 are both provided with adjustment components.

[0040] The cleaning mechanism 3 is installed at the top of the intercepting mechanism 2, and the cleaning mechanism 3 can clean the large particles of sand and gravel in the intercepting mechanism 2.

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

[0042] The adjustment assembly includes an adjustment frame 27, a fixed block 28, a driver 29, a forward and reverse screw 210 and an adjustment frame 211. The adjustment frame 27 is installed at the outer end of the plurality of movable rods 23. Two fixed blocks 28 and two adjustment frames 211 are provided, and the two fixed 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 fixed blocks 28. The forward and reverse screw 210 is installed between the opposite surfaces of the two fixed blocks 28 through bearings. The two adjustment frames 211 are installed on the outer surfaces of the forward and reverse screw 210.

[0043] As can be seen from the above, the driver 29 is started by controlling the control panel 8, so that the forward and reverse screws 210 drive the two adjustment frames 211 thereon to move outward, thereby driving the two middle moving rods 23 to move outward, and then driving the adjustment frame 27 to unfold, so that the unfolded adjustment frame 27 drives the several moving rods 23 thereon to unfold, and through the sliding limit of the several moving rods 23 in the guide groove 22, the several moving rods 23 can respectively drive the several grating plates 24 to unfold stably together, that is, the distance between the several grating plates 24 can be adjusted, so that the several grating plates 24 can flexibly adjust the spacing according to the actual application scenario, and can accurately match the diverse use requirements, especially when dealing with concrete with different particle size distributions or special components, it can enhance the interception effect of the several grating plates 24 on the large sand and gravel particles in the concrete, improve its wide application and high efficiency, thereby avoiding the situation where the large sand and gravel particles block the device, and also improve the smoothness of the concrete during pumping.

[0045] As can be seen from the above, by extending and retracting the diamond-shaped adjustment frame 27, the spacing between several moving rods 23 can be adjusted to achieve the spacing adjustment of multiple grid plates 24. The rectangular adjustment frame 211 may not contact the adjustment frame 27 and does not affect the folding 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] Embodiment 2:

[0047] Reference Figure 5 and Figure 6 As shown, the cleaning mechanism 3 includes a cleaning rod 31, a reciprocating screw rod 32, a support block 33, a protective cover 34 and a driving motor 35. There are two reciprocating screw rods 32, two protective covers 34 and two driving motors 35. The two reciprocating screw rods 32 are both 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 screw rods 32. The two protective covers 34 are respectively installed between the opposite surfaces of two adjacent support blocks 33. The two driving motors 35 are respectively arranged at one end of the two reciprocating screw rods 32;

[0048] A number of fixing plates 36 and a number of cleaning frames 37 are installed on the outer surface of the cleaning rod 31 in an interlaced distribution. A protective sleeve 38 is arranged between the opposite surface of the cleaning frame 37 and the adjacent fixing plate 36. Springs 39 are arranged inside a number of protective sleeves 38.

[0049] As can be seen from the above, when a number of grid plates 24 are adjusted in spacing, a number of fixing plates 36 connected thereto will move synchronously with it and automatically adjust the distance between them. At this time, through the elastic force of the spring 39, a thrust can be applied to the cleaning frame 37, so that the cleaning frame 37 is just located in the middle position between two adjacent fixing plates 36 and also in the middle position between two adjacent grid plates 24. This design ensures that the cleaning frame 37 can be automatically adjusted as the spacing of the grid plates 24 is adjusted, so as to always maintain the position between two adjacent grid plates 24. Then, the control panel 8 is used to control the driving motor 35 to start, so that the reciprocating screw rod 32 drives the cleaning rod 31 to move reciprocally, and then drives a number of fixing plates 36 and a number of cleaning frames 37 to move reciprocally, so that the cleaning frame 37 cleans the large sand and stone particles intercepted by the grid plates 24.

[0050] Preferably, as shown in Figure 5 and Figure 6 the cleaning frame 37 is set to a Y-shaped structure, and the top surface of the cleaning frame 37 is flush with the top surface of the adjustment box 21. The protective sleeve 38 is set to a folding 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 diversion frame 25. The driving motor 35 is electrically connected to the control panel 8.

[0051] As can be seen from the above, the bottom ends of the middle several fixing plates 36 are set to a U-shaped structure, and the bottom ends of the outermost two fixing plates 36 are set to an L-shaped structure, so that the several fixing plates 36 can be automatically adjusted as the grid plates 24 move. The Y-shaped cleaning frame 37 is convenient for pushing the intercepted large sand and stone particles. The folding rubber protective sleeve 38 can be retracted or unfolded as the spacing is adjusted, and can also protect the spring 39, so that the cleaning rod 31 neither contacts the protective cover 34 nor contacts the diversion frame 25.

[0052] Embodiment three:

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

[0054] A conveying shaft 67 is installed on the lower part of the outer wall of the protective box 66 through a bearing, and a conveying blade 68 is installed on the outer surface of the conveying shaft 67. Pulleys 69 are installed on the outer surfaces of the conveying shaft 67 and the outer surface of the driving shaft 62. A synchronous belt 610 is installed between the outer surfaces of the two pulleys 69. A support rod 611 is installed in the middle of the outer wall of the protective box 66, and the other end of the support rod 611 is installed 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 mixing motor 61 to start, so that the driving shaft 62 drives the several mixing paddles 63 and the pulley 69 thereon to rotate together, so that the several mixing paddles 63 can fully mix and stir the concrete in the temporary storage tank 5, and also drive the several connecting blocks 64 to rotate the cleaning wall frame 65 to clean the concrete attached to the inner wall of the temporary storage tank 5, and then through the synchronous transmission of the synchronous belt 610 installed on the two pulleys 69, the conveying shaft 67 drives the conveying blade 68 to rotate, so that the concrete can be stirred while being input into the discharge pipe 9, thereby improving the uniformity and fluidity of the concrete, avoiding the stratification and segregation of the concrete, and avoiding the phenomenon of concrete blocking the pipeline, so that the concrete can be smoothly pumped in the conveying pipe 11, ensuring the construction progress, and avoiding damage to the conveying pump 10.

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

[0057] As can be seen from the above, the protection box 66 can protect the two pulleys 69 and the synchronous belt 610, so that the protection 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 examples:

[0059] This design is used in a variety of complex construction environments with high requirements for concrete transportation, such as the construction of high-rise buildings, the construction of bridges and overpasses, the construction of roads and water conservancy projects, and the construction of mines and tunnels. This design intercepts and separates large sand and gravel particles in the concrete by setting an interception mechanism 2 and adjusting the spacing between several grid plates 24. This design can effectively prevent large sand and gravel particles from clogging the pipeline during pumping, improve the smoothness of pumping, and also improve construction efficiency. The cleaning mechanism 3 is set to clean the large sand and gravel particles intercepted by the interception mechanism 2. This design ensures the continuous and effective operation of the interception mechanism 2 and avoids pumping interruptions caused by blockages. The mixing mechanism 6 is set to stir and mix the concrete and improve the uniformity and fluidity of the concrete. This design helps to reduce the stratification and segregation of concrete during transportation and improve the pumping performance and construction quality of the concrete.
