Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to a simple connection device for reinforced concrete drainage pipes. Background Technology

[0002] Currently, the laying of reinforced concrete drainage pipes often utilizes slings and excavators for hoisting and connection. The method involves folding the sling in half, threading it through the reinforced concrete drainage pipe, then threading the open end of the sling through the closed end, and finally securing the open end to the excavator bucket. The excavator then lifts the pipe, and workers manually support it for connection and laying. After one pipe is laid, the sling is detached from the excavator bucket and pulled out, and the process is repeated for the next pipe. However, this repetitive sling-binding process is time-consuming and labor-intensive, reducing the efficiency of laying reinforced concrete drainage pipes. Furthermore, binding the sling requires a certain level of operator skill, leading to a poor user experience. Utility Model Content

[0026] Please see Figures 1-6 This application provides a technical solution: a simple connection device for reinforced concrete drainage pipes, including a lifting sling 110, a connector 130, a braided steel strip 140, a U-shaped steel rod 160, a roller 170, and a second self-locking buckle 180. The connector 130 is installed on one end of the lifting sling 110. The device also includes a first self-locking buckle 120, which is installed between the lifting sling 110 and the connector 130. The first self-locking buckle 120 is provided with several sets.

[0027] A braided steel strap 140 is installed on the other end of the lifting sling 110. A connector 130 is fitted onto a U-shaped steel rod 160. A roller 170 is rotatably mounted on the U-shaped steel rod 160. The lifting sling 110 passes through the U-shaped steel rod 160. A second self-locking buckle 180 is installed on the braided steel strap 140. In this embodiment, both the first self-locking buckle 120 and the second self-locking buckle 180 are carabiners. A steel ring 150 is also included, which is fixed to the braided steel strap 140. One of the second self-locking buckles 180 is fastened to the steel ring 150. On the 0, there are several second self-locking buckles 180, and two adjacent second self-locking buckles 180 are fastened together. The lifting sling 110 is made of ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene has a lower density than water, is wear-resistant, chemically resistant, and has excellent impact resistance and low-temperature performance. The braided steel strip 140 has mounting holes 190, and the steel ring 150 is installed in the mounting holes 190. The mounting holes 190 facilitate the installation of the steel ring 150. The thickness of the lifting sling 110 is 2mm-4mm.

[0028] The working principle and process of this utility model are as follows: In use, one of the first self-locking buckles 120 is opened, then the two first self-locking buckles 120 are separated. The lifting strap 110 is then passed through the reinforced concrete drainage pipe. The first self-locking buckles 120 are then fastened together. The assembled second self-locking buckles 180 are then wound around the bucket, and the end of the second self-locking buckle 180 is fastened to the other second self-locking buckles 180. The excavator then operates, lifting the reinforced concrete drainage pipe under the action of the U-shaped steel rod 160 and the roller 170. The reinforced concrete drainage pipe is then manually supported. The pipes can then be connected and laid. After laying, the first self-locking buckle 120 is released, and then the lifting sling 110 is pulled out. Then, the next reinforced concrete drainage pipe can be connected and laid following the above steps. The simple connection device for reinforced concrete drainage pipes uses the first self-locking buckle 120 to open and close the lifting sling 110 and the connector 130, avoiding repeated binding of the lifting sling 110, saving time and effort. In addition, the second self-locking buckle 180 saves binding time and does not require skilled workers, improving the laying efficiency of reinforced concrete drainage pipes and bringing a better user experience.

[0029] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
