Technical Field

[0001] The patent of this invention relates to the technical field of ultra-high performance concrete, specifically, to ultra-high performance concrete distribution equipment with uniform distribution. Background Art

[0002] Ultra-high performance concrete (UHPC), as a new type of high-performance building material, has excellent properties such as high strength, high toughness and low permeability, and is being increasingly widely used in modern engineering construction.

[0003] However, during the construction process, there has always been a problem of uneven distribution of ultra-high performance concrete.

[0004] In existing technologies, on the one hand, fixed concrete placing booms have a limited distribution range, making it difficult to meet the needs of large-scale construction, and easily leading to uneven concrete distribution. On the other hand, the single spiral placing method is prone to uneven distribution of concrete due to the high viscosity of ultra-high performance concrete.

[0005] In addition, many existing concrete distribution equipment lacks efficient mixing functions for concrete. Ultra-high performance concrete is prone to segregation during the transportation and distribution stages, and conventional mixing devices are difficult to ensure its uniformity. At the same time, some equipment is not flexible in adjusting the distribution height and angle, and cannot adapt to the needs of different construction scenarios, exacerbating the problem of uneven distribution.

[0034] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.

[0035] Ultra-high performance concrete distribution equipment for uniform distribution includes longitudinal guide rails 101 arranged on both sides of a roadbed 100, a transverse frame 102 provided on the two longitudinal guide rails 101, the transverse frame 102 having transverse guide rails and a hollow area 103 arranged transversely and connected to the roadbed 100, the transverse guide rails and the hollow area 103 being arranged across the roadbed 100;

[0036] A distribution frame 200 is provided on the transverse frame 102 and moves laterally along the transverse guide rail. A distribution drum 201 is provided on the distribution frame 200. A distribution drum 201 has a distribution cavity for accommodating ultra-high performance concrete. The top of the distribution cavity forms an inlet 202, and the bottom of the distribution cavity forms an outlet 203. A middle plate is provided in the middle of the distribution cavity. The distribution cavity has an upper cavity 204 located above the middle plate and a lower cavity 205 located below the middle plate. The middle plate is provided with a plurality of communicating holes extending vertically therethrough.

[0037] A longitudinally arranged stirring shaft 300 is provided in the upper chamber 204. A horizontally arranged rotating disk 302 is provided at the bottom of the stirring shaft 300, with a rotating gap between the bottom of the rotating disk 302 and the middle plate. A plurality of longitudinal shafts 303 extending longitudinally upward are provided on the rotating disk 302. The plurality of longitudinal shafts 303 are arranged at intervals around the circumference of the stirring shaft 300.

[0038] After the transverse frame 102 moves along the longitudinal guide rail 101 for a set step length, the distribution frame 200 moves transversely along the transverse frame 102, and the ultra-high performance concrete enters the upper cavity 204 through the feed port 202. The stirring shaft 300 drives the rotating disk 302 and the longitudinal shaft 303 to rotate synchronously. The stirring shaft 300 and the longitudinal shaft 303 stir the ultra-high performance concrete longitudinally, and the rotating disk 302 stirs the ultra-high performance concrete horizontally, and squeezes the ultra-high performance concrete in the rotating interval through the connecting hole into the lower cavity 205. The ultra-high performance concrete in the lower cavity 205 falls through the discharge port 203, passes through the hollow area 103, and is arranged on the roadbed 100 to form a distribution layer.

[0039] The above-mentioned ultra-high performance concrete distribution equipment with uniform distribution, firstly, has a structural setting that enables longitudinal and transverse bidirectional movement of the distribution frame 200. Through the cooperation of the longitudinal guide rail 101 and the transverse frame 102, the distribution frame 200 can accurately cover the construction area of ​​the roadbed 100, thus ensuring that the concrete is evenly distributed across the entire roadbed 100.

[0040] Secondly, the combination of the stirring shaft 300, the rotating disk 302, and the longitudinal shaft 303 in the distribution chamber achieves sufficient mixing of the ultra-high performance concrete in the longitudinal and horizontal directions, avoiding the problem of concrete segregation caused by insufficient mixing, thereby ensuring the uniformity of the concrete before distribution;

[0041] Finally, the connecting holes on the middle plate allow the mixed ultra-high performance concrete to evenly flow from the upper cavity 204 into the lower cavity 205 and fall smoothly onto the roadbed 100 through the discharge port 203, thus avoiding uneven distribution of the ultra-high performance concrete due to impact force or deviation in distribution direction during its falling process.

[0042] In this embodiment, the upper cavity 204 is connected to a material delivery pipe, which is in communication with the feed port 202 . The ultra-high performance concrete is transported through the material delivery pipe and enters the upper cavity 204 from the feed port 202 .

[0043] In this way, concrete can enter the distribution cavity stably and continuously, providing a reliable material supply for subsequent mixing and distribution processes, and avoiding interruption or uneven distribution caused by poor feeding.

[0044] In this embodiment, the top of the stirring shaft 300 passes through the top of the distributing cylinder 201. The top of the distributing cylinder 201 is provided with a motor 301. The motor 301 is connected to the stirring shaft 300 to drive the stirring shaft 300 to rotate.

[0045] In this way, a stable and powerful power source is provided for the mixing process, ensuring that the mixing shaft 300 can fully mix the concrete at a sufficient speed and torque, thereby ensuring the uniformity of the concrete.

[0046] In this embodiment, the feed port 202 is formed on the side of the distribution barrel 201 and is offset from the stirring shaft 300; in this way, position interference between the feed port 202 and the stirring shaft 300 is avoided, and unnecessary collision or obstruction between the material and the stirring shaft 300 during the feeding process is prevented, thereby reducing the risk of material accumulation or uneven distribution.

[0047] In this embodiment, the bottom of the rotating disk 302 has a bottom surface, the middle portion of the bottom surface is recessed to form a bottom groove 304 with an open bottom, and the bottom groove 304 is arranged toward the rotation interval.

[0048] By arranging the bottom groove 304, the ultra-high performance concrete can flow toward the middle of the rotating interval, making it easier for the rotating disk 302 to horizontally stir the ultra-high performance concrete and squeeze the ultra-high performance concrete through the connecting holes, thereby enhancing the horizontal fluidity of the concrete and allowing the concrete to pass through the connecting holes more evenly into the lower cavity 205, thereby improving the uniformity of the distribution.

[0049] In this embodiment, the outer periphery of the bottom groove 304 forms an annular wall, and the annular wall is provided with a plurality of notches 305 . The plurality of notches 305 are arranged around the circumference of the rotating disk 302 at intervals. The bottom groove 304 is laterally connected to the outside through the notches 305 .

[0050] This helps prevent excessive accumulation of concrete at the edge of the rotating disk 302, and the notches 305 allow the concrete to flow evenly from the sides into the bottom groove 304, further promoting uniform distribution of the concrete.

[0051] In this embodiment, the top of the rotating disk 302 is provided with a plurality of arcuate grooves 306, which are arranged around the circumference of the rotating disk 302 at intervals. The arcuate grooves 306 are arranged in an arc-shaped curved shape along the circumference of the rotating disk 302. The bottom of the longitudinal shaft 303 has a bottom head 307, which is movably disposed in the arcuate groove 306.

[0052] During the horizontal rotation of the rotating disk 302 , the bottom head 307 moves in an arc shape along the arc groove 306 , and the longitudinal axis 303 moves in an arc shape relative to the rotating disk 302 .

[0053] The structural arrangement of the rotating disk 302 enables the longitudinal shaft 303 to generate an arc movement during the rotation process, thereby enhancing the stirring effect of the stirring shaft 300 , allowing the concrete to be more fully mixed in the distribution cavity, and improving the uniformity of the concrete.

[0054] In this embodiment, an elastic ring is connected to the middle part of the multiple longitudinal shafts 303, which is arranged around the circumference of the rotating disk 302 and fixedly connected to the middle part of each longitudinal shaft 303; during the horizontal rotation of the rotating disk 302, the multiple longitudinal shafts 303 move in an arc relative to the rotating disk 302, the elastic ring elastically deforms, and drives the multiple longitudinal shafts 303 to move in an arc and reset.

[0055] By providing the elastic ring, elastic support is provided for the movement of the longitudinal shaft 303, so that the longitudinal shaft 303 can flexibly adapt to the flow state of the concrete during the mixing process, thereby enhancing the flexibility and adaptability of the mixing and further improving the uniformity of the concrete.

[0056] In this embodiment, the discharge port 203 is arranged in a flat strip shape, and the side of the discharge port 203 is connected to the inclined guide plate 206. The upper end of the guide plate 206 is connected to the material distribution drum 201, and the lower end of the guide plate 206 extends downwardly. The discharge port 203 and the guide plate 206 are inclined relative to each other. The ultra-high performance concrete discharged from the discharge port 203 falls on the guide plate 206 and falls downward on the roadbed 100 along the inclined direction of the guide plate 206.

[0057] The combination of the flat strip discharge port 203 and the inclined guide plate 206 helps to control the falling direction and speed of the concrete, so that the concrete can be evenly distributed on the roadbed 100, reducing the uneven distribution problem caused by uneven discharge.

[0058] In this embodiment, the lower cavity 205 protrudes outward to form a protruding area 207. The protruding area 207 is arranged away from the inclined plate. A rolling gear shaft 208 is provided in the protruding area 207. The gear shaft 208 extends toward the discharge port 203 and spans above the discharge port 203.

[0059] By providing the gear shaft 208, a certain guiding and rectifying effect can be achieved during the falling process of the concrete, which helps to maintain the stability of the falling concrete and further ensures the uniformity of the distribution.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
