Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a civil engineering construction pouring device. Background Technology

[0002] Concrete pouring is the process of pouring concrete into a mold until it hardens. In civil engineering, concrete and other materials are placed into a mold to form a predetermined shape. A civil engineering pouring device is an auxiliary device used in the construction process to pour concrete into a mold; it is widely used in the construction industry.

[0003] Traditional civil engineering pouring equipment includes a pouring machine and a pouring pipe. The pouring machine directly fills the pipe and outputs concrete. Workers hold the pouring pipe to pour concrete, which has low work efficiency. If the pouring pipe is thick, it requires multiple people to hold it, which is inconvenient.

[0004] To address the aforementioned issues, patent document CN218643887U discloses a civil engineering construction pouring device, comprising a support box, a feeding and conveying assembly, a transmission pipe, and an adjustable vibrating discharge assembly. The support box contains a supporting vertical rod, the upper end of which extends beyond the upper opening of the support box. The upper end of the supporting vertical rod is L-shaped bent, and an adjusting ring is fixedly mounted on the bent portion of the upper part of the supporting vertical rod away from the rod. The adjustable vibrating discharge assembly passes through the adjusting ring. The feeding and conveying assembly is located within the support box, and the transmission pipe connects the feeding and conveying assembly and the adjustable vibrating discharge assembly. The feeding and conveying assembly includes a pouring pipe, a pouring head, a support spring, and a vibration motor. This civil engineering construction pouring device utilizes a support structure to replace manual handling, allows adjustment of the discharge height and the angle of the discharge path, enables adjustable vibrating discharge, accelerates discharge, and avoids material accumulation that could cause pouring difficulties.

[0005] Based on the above search and combined with existing technologies, it was found that although existing civil engineering pouring devices can replace manual handling with support structures, their support structures are inconvenient to move, thus limiting them to fixed-point construction. However, civil engineering construction often requires mobile pouring operations, and using these devices after replacing manual handling is inconvenient. In addition, the aforementioned technologies and other civil engineering pouring devices all have the drawback of not being compatible with traditional pouring devices, requiring a complete replacement of the original devices, which increases the equipment replacement cost of civil engineering construction. Therefore, a new civil engineering pouring device is needed. Utility Model Content

[0014] The end of the pull rod near the support shaft is integrally formed with a slip ring, which is slidably sleeved on the support shaft. The inner side of the slip ring is fixed with a sliding rib that slides in conjunction with the sliding groove.

[0015] The lower end of the slip ring is elastically connected to the upper end of the adapter shaft via a spring.

[0016] Preferably, the solid wheel is rotatably connected to the lower end of the support rod via a tapered bearing, and the cross-sectional diameter of the tapered bearing near the solid wheel is larger than the cross-sectional diameter of the tapered bearing and the lower end of the support rod that are fixed together.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example: Reference Figures 1-5 The shown civil construction pouring device includes a connecting pipe 1, an intermediate pipe 2 and a pouring head pipe 3. The connecting pipe 1 is fixedly connected to the output port of the existing pouring pipe, the intermediate pipe 2 is fixedly connected to the lower end of the connecting pipe 1, the outer diameter of the intermediate pipe 2 is the same as the inner diameter of the connecting pipe 1, and the pouring head pipe 3 is fixedly sleeved on the lower end of the intermediate pipe 2.

[0034] A connecting hoop 4 is rotatably sleeved on the intermediate pipe 2, and the connecting hoop 4 is located between the connecting pipe 1 and the casting head pipe 3;

[0035] Support legs 5 are detachably installed on the four sides of the connecting hoop via connectors. Support legs 5 are L-shaped support rods. A solid wheel 6 is rotatably connected to the lower end of the support legs 5. The solid wheel 6 is a thin solid disc.

[0036] The upper part of the support leg 5 is equipped with a pull rod 7, which is convenient for staff to hold and pull.

[0037] Based on the above structure, during use, the workers connect and fix the connecting pipe 1 to the existing pouring pipe, thereby improving the existing pouring pipe. After installation, the support leg 5 and the solid wheel 6 can support the connecting pipe 1, the intermediate pipe 2 and the pouring head pipe 3, thereby achieving stable support for the existing pouring pipe. At the same time, the workers can move it by pulling the pull rod 7 without having to hold the pouring pipe directly by hand, making the movement more convenient and easier. This reduces the workload of the workers and makes the pouring operation more convenient.

[0038] In addition, this civil engineering construction pouring device can be better integrated with existing pouring pipes, greatly reducing the cost of improving existing civil engineering construction pouring devices, and is suitable for widespread use.

[0039] Furthermore, connecting lugs 41 are fixed around the four sides of the connecting hoop;

[0040] The support leg 5 includes a connecting rod 51, a support rod 52, and an adapter shaft head 53. The connecting rod 51 is detachably fixed to the connecting lug 41 by bolts. The end of the connecting rod 51 away from the connecting lug 41 is rotatably connected to the support rod 52 through the adapter shaft head 53. The end of the support rod 52 away from the adapter shaft head 53 is rotatably connected to the solid wheel 6.

[0041] By setting the connecting rod 51, support rod 52 and adapter shaft head 53, the rotating part of the solid wheel 6 is set at a high point, which can avoid the restriction of the solid wheel 6 rotation by the concrete during pouring. That is, the rotating part will not be affected by the seepage of concrete, and the equipment itself has a good protection effect while ensuring the rotation of the solid wheel 6.

[0042] Furthermore, a support shaft 9 is fixed to the upper end of the adapter shaft head 53. The support shaft 9 is a vertical shaft and a limiting end with a large diameter is formed at the upper end of the support shaft 9. A vertically extending slide groove 91 is provided on the support shaft 9.

[0043] The end of the pull rod 7 near the support shaft 9 is integrally formed with a slip ring 71. The slip ring 71 is slidably sleeved on the support shaft 9. The inner side of the slip ring 71 is fixed with a sliding rib 711 that slides in cooperation with the sliding groove 91.

[0044] The lower end of the slip ring 71 is elastically connected to the upper end of the adapter shaft head 53 via a spring 72.

[0045] By using the support shaft 9 and spring 72, the pull rod 7 can be easily pulled by the workers while also sliding up and down. This not only allows it to be used by workers of different heights within a certain range, but also reduces the vibration force transmitted by the pouring pipe during pouring, thereby reducing the impact of the vibration generated by the pouring pipe on the workers and further reducing the burden on the workers during the pouring operation.

[0046] Furthermore, the solid wheel 6 is rotatably connected to the lower end of the support rod 52 via a tapered bearing 61, and the cross-sectional diameter of the tapered bearing 61 near the solid wheel 6 is larger than the cross-sectional diameter of the tapered bearing 61 and the lower end of the support rod 52 that are fixed together.

[0047] The shaft in the middle of the tapered bearing seat 61 rotates through the solid wheel 6, and the shaft in the middle of the tapered bearing seat 61 extends to one end of the solid wheel 6, which is integrally formed with a scraper 62 that fits against the side wall of the solid wheel 6.

[0048] By setting the tapered bearing 61, the wear caused by concrete to the middle of the solid wheel 6 during pouring can be reduced. When the solid wheel 6 rotates, the scraper 62 is relatively stationary, so that the scraper 62 can scrape off the concrete adhering to the solid wheel 6. This can prevent the solid wheel 6 from being affected by a lot of concrete adhering to it during use. In addition, it is also easy to clean the concrete adhering to the solid wheel 6 after use.

[0049] Furthermore, multiple extending vertical strips 31 are formed at the lower end of the pouring head pipe 3. The multiple extending vertical strips 31 extend vertically downward and have gaps between them. The extending vertical strips 31 can limit the diffusion trend of concrete, thereby reducing the amount of concrete splashing during pouring, thus reducing the probability of concrete splashing on the workers' clothes, protecting the workers, and also reducing concrete waste.

[0050] Furthermore, multiple vertically arranged sealing gaskets 11 are fixed inside the connecting pipe 1, and a fixing ring 12 is fixedly sleeved on the upper outer side of the connecting pipe 1. A fastening bolt 8 is screwed onto the fixing ring 12. The fastening bolt 8 penetrates the wall of the connecting pipe 1 horizontally and its end is fixed by friction with the outer wall of the existing casting pipe. After the connecting pipe 1 is sleeved onto the end of the existing casting pipe, the workers can fix the connection between the two by tightening the fastening bolt 8, thereby making the connection more stable.

[0051] The end of the fastening bolt 8 away from the connecting pipe 1 has a hand-tightening part 81 and a hexagonal cap part 82. The hand-tightening part 81 is provided with anti-slip texture. By providing the hand-tightening part 81 and the hexagonal cap part 82, multiple operating conditions can be provided. That is, it can be tightened by using tools or by hand. The diversified operation is more flexible and convenient.

[0052] The working principle of this utility model is as follows: In daily use, the staff first puts the connecting pipe 1 on the lower end of the existing pouring pipe, and then tightens the fastening bolt 8 to fix the two together, so that the connection is more stable; thus, the civil construction pouring device can be adapted and connected with the existing pouring pipe, so as to achieve the purpose of better integration with the existing pouring pipe, greatly reducing the cost of improving the existing civil construction pouring device, and is suitable for widespread use.

[0053] After installation, the support leg 5 and solid wheel 6 can support the connecting pipe 1, intermediate pipe 2 and pouring head pipe 3, thereby achieving stable support for the existing pouring pipe. At the same time, the workers can move it by pulling the lever 7 without having to hold the pouring pipe by hand. The movement is more convenient and easier, which reduces the workload of the workers and makes the pouring operation more convenient.

[0054] In addition, the support shaft 9 and spring 72 enable the pull rod 7 to slide up and down while making it easy for workers to pull the rod. This not only allows it to be used by workers of different heights within a certain range, but also reduces the vibration force transmitted by the pouring pipe during pouring, thereby reducing the impact of the vibration generated by the pouring pipe on the workers and further reducing the burden on the workers during the pouring operation.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
