Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to pouring equipment for prefabricating and processing concrete U-shaped channels. Background Art

[0002] In water conservancy projects and agricultural projects, pipes and channels are often used to achieve the purpose of water diversion. For long-distance irrigation and water delivery, due to the high cost of pipelines and the difficulty of construction, channel projects with relatively low cost and simple construction are generally selected. There are two commonly used channel projects: earthen channels and concrete channels. The country is increasingly advocating water-saving irrigation. Earthen channel projects are gradually being eliminated due to their large infiltration volume and low utilization rate. Commonly used concrete channels are divided into precast concrete slabs and cast-in-place concrete channels. Precast concrete slabs are produced in a fixed place using fixed molds. After the concrete reaches the designed strength, it is transported to the construction site for laying.

[0003] After searching, Chinese patent number CN215367110U is a concrete U-shaped channel forming device, which pours concrete on site by setting a vibration structure. The on-site poured concrete channel is processed according to the design size requirements. The equipment is placed in the excavated U-shaped channel, and the equipment moves forward as the concrete is poured. Due to the small vibration of the equipment, the concrete strength is low and the surface honeycomb surface is serious, which increases the surface roughness and reduces the water flow rate. It is not conducive to the rapid installation of the U-shaped channel, prolongs the working time and reduces the work efficiency. Therefore, a pouring equipment for prefabricated processing of concrete U-shaped channels is proposed to solve the above problems. Utility Model Content

A rotating rod 302 is provided, and a first bevel gear 303 is provided on the outer surface of the rotating rod 302. A second bevel gear 304 is provided on the top of the first bevel gear 303. A second threaded rod 305 is fixedly installed on the top of the second bevel gear 304. A moving rod 306 is provided on the outer surface of the second threaded rod 305.

A slide 309 is provided inside the moving rod 306. A spring 310 is fixedly installed inside the slide 309. Blocks 311 are fixedly installed on the left and right sides of the spring 310.

[0025] like Figure 1 and Figure 2 As shown, two threaded sleeves 5 are fixedly installed on the left and right sides of the upper mold 4, and a through hole 6 is opened on the top of the working chamber 1. When the upper mold 4 is moved, the two groups of threaded sleeves 5 move on the outer surfaces of the two groups of first threaded rods 8, and then the upper mold 4 moves up and down.

[0026] like Figure 1 and Figure 2 As shown, four motors 7 are fixedly installed on the top of the working chamber 1, and the output shafts of the motors 7 are fixedly connected to the first threaded rods 8. When the four motors 7 are started, the four first threaded rods 8 drive the four threaded sleeves 5 to move, so that the upper part of the upper mold 4 passes through the through hole 6, thereby facilitating the demolding of the U-shaped channel.

[0027] like Figure 1 and Figure 2 As shown, the top of the upper mold 4 extends to the outside of the working chamber 1 through the through hole 6, and the two sets of threaded sleeves 5 and the two sets of first threaded rods 8 are all threadedly connected. Start the motor 7 to make the upper mold 4 fall on the top of the lower mold 2 to ensure that the upper mold 4 and the lower mold 2 can fit tightly.

[0028] like Figure 1 and Figure 2 As shown, the bottom end of the first threaded rod 8 passes through the working chamber 1 and extends to the interior of the working chamber 1. The top of the upper mold 4 is fixedly connected with a feed pipe 9, and concrete is poured into the upper mold 4 and the lower mold 2 from the feed pipe 9 to complete the molding of the concrete.

[0029] like Figure 2 and Figure 4 As shown, the opposite ends of the two rotating rods 302 pass through the two first cavities 301 and extend to the outside of the lower mold 2. The two first bevel gears 303 and the two second bevel gears 304 are meshed. When the two rotating rods 302 are rotated, the two first bevel gears 303 drive the two second bevel gears 304 to rotate, and the two second threaded rods 305 rotate, driving the two moving rods 306 to move.

[0030] like Figure 2 and Figure 4 As shown, the top ends of the two moving rods 306 pass through the upper mold 4 and the lower mold 2 and extend to the inside of the two second cavities 307. The two groups of blocks 311 and the two groups of slots 308 are all clamped. When the two moving rods 306 enter the inside of the two second cavities 307, the two springs 310 are compressed and the two groups of blocks 311 are retracted to the inside of the two slides 309. When they reach the position of the two groups of slots 308, the two springs 310 rebound, causing the two groups of blocks 311 to be clamped to the two groups of slots 308.

[0031] During implementation, follow these steps:

[0032] 1) First, start the four motors 7 to rotate the four first threaded rods 8;

[0033] 2) Then the four first threaded rods 8 drive the four threaded sleeves 5 to move downward, so that the upper mold 4 and the lower mold are fitted together;

[0034] 3) Rotate the two rotating rods 302 again, allowing the two moving rods 306 to move into the two second cavities 307, and the two sets of clamping blocks 311 engage with the two sets of clamping slots 308;

[0035] 4) Finally, concrete is poured into the interior of the upper mold 4 and the lower mold 2 from the feeding pipe 9 .

[0036] To sum up, the pouring equipment for prefabrication of concrete U-shaped channels is equipped with a fixed structure 3. When pouring concrete, the motor 7 is started to make the upper mold 4 fall on the top of the lower mold 2, and then the two rotating rods 302 are rotated to rotate the two second threaded rods 305. The two moving rods 306 enter the two second cavities 307, and the two groups of blocks 311 are engaged with the two groups of slots 308. Then, the concrete is poured into the upper mold 4 and the lower mold 2 through the feed pipe 9, thereby completing the pouring function of the U-shaped channel.
