Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a bridge pouring equipment for bridge construction. Background Technology

[0002] Bridge structures are the main structures in transportation engineering. The cast-in-place method is widely used because it eliminates the need for scaffolding, saves costs, minimizes mutual interference, and is highly adaptable. The most important process in the construction of reinforced concrete bridges is concrete casting, which refers to the process of pouring concrete into a mold until it is plasticized.

[0003] Chinese Patent No. CN212103676U discloses a concrete pouring device for bridge construction, including a feeding box, a top cover, a pouring box, and casters. The feeding box is welded to one side of the pouring box, and the top cover is fitted onto the top of the pouring box. Casters are installed at the bottom of both the pouring box and the feeding box. The feeding box includes a feeding chamber, a mixing chamber, a fixing block, a swing blade, a mixing paddle, and a partition. A baffle is embedded inside the pouring box. The baffle includes a pouring pump, an inlet pipe, an outlet pipe, and a pouring pipe. A positioning plate is provided on one side of the baffle, and the positioning plate has a rotating shaft and a mixing rod. A support column is provided on the other side of the baffle, and a rotating wheel is installed at the bottom of the support column. The rotating wheel has teeth around its circumference. The mixing rod inside the pouring box continuously mixes the concrete to prevent sedimentation and insufficient concrete purity, which would affect the pouring effect. The concrete flows out through the pouring pipe to the upper layer of the bridge under the action of the pouring pump, thereby achieving the purpose of pouring.

[0004] However, the above technical solution has the following shortcomings: the device automatically introduces concrete into the pouring box through the gap of the partition. This conveying method makes it difficult to control the mixing time of the concrete in the mixing chamber, thus failing to achieve good mixing and affecting the quality of concrete mixing.

[0020] Example 1

[0021] like Figure 1 - Figure 4 As shown in the figure, the bridge pouring equipment for bridge construction proposed in this embodiment includes a vehicle body 1 and a mixing device; a box body 2 is provided on the vehicle body 1.

[0022] The stirring device includes a first motor 3 mounted on a housing 2, a main shaft 4 rotatably connected inside the housing 2, three first mounting rings 5 ​​equidistantly distributed on the main shaft 4, six stirring blades 6 arranged in an annular array on the first mounting rings 5, a second mounting ring 7 mounted on the main shaft 4, a baffle 8 arranged in an annular array on the second mounting rings 7, five first scraper plates 9 arranged in an annular array at the bottom end of the main shaft 4 and slidably connected to the housing 2, a connecting frame 10 mounted on the main shaft 4, and three second scraper plates 11 mounted on the connecting frame 10 and slidably connected to the housing 2; the first motor 3 and the main shaft 4 are driven together, and the baffle 8 has multiple support rods located between the upper and lower sets of stirring blades 6.

[0023] In this embodiment, after the material is conveyed into the interior of the housing 2, the first motor 3 is started to drive the main shaft 4 to rotate. The main shaft 4 simultaneously drives the first mounting ring 5 and the second mounting ring 7 to rotate. The first mounting ring 5 drives multiple stirring blades 6 to stir and mix the material. The second mounting ring 7 drives multiple baffles 8 to rotate. With the support rods on the baffles 8, the material inside the housing 2 is fully agitated to improve the fluidity of the material during stirring and mixing, thereby improving the efficiency of uniformly mixing the material. When the main shaft 4 rotates, it also drives the first scraper 9 and the connecting frame 10 to rotate. The connecting frame 10 drives the second scraper 11 to rotate, so that the first scraper 9 and the second scraper 11 slide against the bottom and side surfaces of the housing 2, respectively, to scrape off some of the material adhering to the inner wall of the housing 2, further improving the processing effect of the raw materials and having good practicality.

[0024] Example 2

[0025] like Figure 1 and Figure 3 As shown in the figure, the bridge pouring equipment for bridge construction proposed in this embodiment, compared with the first embodiment, has a feeding device on the vehicle body 1. The feeding device includes a conveyor seat 12, a feeding hopper 13 and a discharge pipe 24 on the conveyor seat 12, and a drive assembly on the conveyor seat 12. The discharge pipe 24 is connected to the box body 2. The drive assembly includes a second motor 21 on the vehicle body 1, a rotating rod 22 rotatably connected to the conveyor seat 12, and a spiral blade 23 on the rotating rod 22. The second motor 21 and the rotating rod 22 are drivenly connected.

[0026] In this embodiment, raw materials can be fed into the interior of the conveying seat 12 through the feeding hopper 13. Then, the rotating rod 22 is driven to rotate by the second motor 21, so that the rotating rod 22 drives the spiral blade 23 to carry out the conveying. During the conveying process, the preliminary mixing and stirring operations can be completed simultaneously, which is beneficial to the subsequent mixing and stirring of the materials. Finally, the materials enter the interior of the box 2 through the discharge pipe 24.

[0027] Example 3

[0028] like Figure 3 and Figure 4 As shown in the figure, the bridge pouring equipment for bridge construction proposed in this embodiment, compared with the second embodiment, has an inclined platform 14 on the feed hopper 13, a rotating plate 15 rotatably connected to the inclined platform 14, and a switch assembly inside the feed hopper 13. The switch assembly includes a fixed cylinder 16 inside the feed hopper 13, a spring 17 inside the fixed cylinder 16, a telescopic rod 18 slidably connected to the fixed cylinder 16 and with one end set on the spring 17, and a top ball 19 set on the telescopic rod 18 and abutting against the rotating plate 15.

[0029] The telescopic rod 18 is provided with two symmetrically distributed guide sliders 20, and the inside of the fixed cylinder 16 is provided with a groove for the guide sliders 20 to slide horizontally.

[0030] In this embodiment, when the material is poured into the upper hopper 13, the material slides down the inclined platform 14 and the rotation plate 15 is caused by gravity to open the opening of the feed hopper 13. At the same time, the rotation plate 15 compresses the spring 17 by squeezing the top ball 19. After a batch of material enters the feed hopper 13, the rotation plate 15 will close the opening of the feed hopper 13 again under the elastic force of the spring 17, which prevents a large amount of dust from escaping from the feed hopper into the surrounding air. In addition, the guide slider 20 can guide and limit the movement of the telescopic rod 18, control the movement distance of the telescopic rod 18 and prevent the spring 17 from bending or twisting, thus ensuring the service life of the spring 17.

[0031] Example 4

[0032] like Figure 1 As shown in the figure, the bridge pouring equipment for bridge construction proposed in this embodiment, compared with the first embodiment, has a pouring box 25 on the vehicle body 1, a pouring pipe 26 with telescopic function on the pouring box 25, and the pouring box 25 and the box body 2 are connected.

[0033] In this embodiment, the pouring box 25 adopts the structure designed by the utility model patent with patent publication number CN212103676U. The pouring pipe 26 is equipped with a telescopic mechanism. The pouring pipe 26 is driven to extend and retract by the tooth on the rotating wheel, so that the extension and retraction of the pouring pipe 26 changes the pouring range of concrete. In addition, the pouring box 25 is equipped with a pump for extracting the slurry inside the box 2, so as to pour the evenly mixed slurry through the pouring pipe 26 for construction.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
