Description

Technical Field

[0001] The invention relates to the technical field of pipeline assembly, and in particular to a large-diameter pipeline butt-jointing and fixing device. Background Art

[0002] In the construction of water conservancy facilities, it is necessary to lay pipes.

[0003] When laying large-diameter pipelines, it is generally necessary to dig trenches first (the trench depth is 4-7m). Due to the large size and weight of the pipelines, the pipelines are generally hoisted into the trenches by cranes, and the two sections of the pipelines are pre-jointed before welding. For example, a pipe section fixing device for assembling large-diameter pipelines is disclosed in the patent authorization announcement number CN 217727728 U.

[0004] Due to the limitations and influence of the working environment, the above operations are often difficult. One is that it is difficult to move the pipeline. The up and down movement of the pipeline can be operated by a crane, which is slightly easier, but the lateral movement of the pipeline is more difficult, especially when the two sections of the pipeline need to be pre-jointed. Moreover, after the crane releases the lifting of the pipeline, the pipeline enters the groove, which may cause the groove to sink or sag due to the weight of the pipeline, causing the two pre-aligned sections of the pipeline to shift; another is that after the two sections of the pipeline are pre-aligned, a working pit needs to be reserved for the construction workers to operate, which increases the workload of the groove switch. Moreover, there are certain risks for workers to enter and perform welding operations in the working pit for a long time, and the entry of welding equipment is also a problem.

[0005] Alternatively, auxiliary devices may be used to connect the two pipe sections in the groove. However, it is difficult to dismantle and recycle the auxiliary devices. Summary of the invention

[0006] In view of the problems pointed out in the background technology, the present invention proposes a large-diameter pipe docking and fixing device to solve the above technical problems.

[0007] The technical solution of the present invention is achieved in this way:

[0008] A large diameter pipe butt fixing device,

[0009] Including a deformable connecting pipe;

[0010] Both ends of the connecting pipe are respectively connected with an annular fixing ring;

[0011] The fixing ring is connected with an annular embracing frame, and the embracing frame is composed of an upper embracing frame and a lower embracing frame, and both the upper embracing frame and the lower embracing frame are detachably connected to the fixing ring.

[0012] The present invention is further configured such that the connecting pipe is made of a flexible material.

[0013] The present invention is further configured such that a supporting tube is connected inside the connecting tube.

[0014] The present invention is further configured such that the cross-sections of the upper embracing frame and the lower embracing frame are both U-shaped structures opening inwards, and the outer sides of one ends of the upper embracing frame and the lower embracing frame are respectively provided with connecting rings connected to the fixing ring.

[0015] The present invention is further configured such that grouting holes communicating with the inside and outside of the upper embracing frame and the lower embracing frame are provided on the side walls.

[0016] The present invention is further configured such that the support tube is composed of a plurality of annular tube bodies, the plurality of tube bodies are arranged at intervals in the axial direction of the connecting tube, and the tube bodies are fixedly connected to the inner wall of the connecting tube.

[0017] The present invention is further configured such that insertion grooves are respectively provided on the facing surfaces of the two fixing rings, and the insertion grooves are arranged in the up and down directions. Two insertion grooves are provided on one fixing ring, and the two insertion grooves are respectively located on the left and right sides of the fixing ring; it also includes a surrounding plate, and the two ends of the surrounding plate are respectively connected to the insertion grooves on the same side of the two fixing rings; it also includes a cover plate fixedly connected to the upper side of the surrounding plate, and the cover plate is provided with grouting holes.

[0018] The present invention is further configured such that the left and right sides of the fixing ring are respectively provided with fixing edges, the fixing edges are provided with fixing holes, and the fixing holes are connected with gripping nail posts.

[0019] The present invention is further configured such that a bottom plate is provided on the lower side of the connecting tube, the two ends of the bottom plate are respectively hinged to the fixing rings at the two ends of the connecting tube, the middle part of the bottom plate is disconnected, the two bottom plates formed after the disconnection are hinged to each other, and the bottom plate is higher than the lower end of the fixing ring.

[0020] The present invention is further configured such that the circumferential ends of the upper embracing frame and the lower embracing frame are detachably connected by screws.

[0021] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

The two ends of the pipeline are respectively connected to the lower embracing frame, and then the upper embracing frame is installed. In this way, the two pipelines can be connected with the help of the connecting pipe. Since the connecting pipe can be deformed, even if a certain displacement occurs during the installation of the pipeline, the connecting pipe can also be deformed accordingly, thus ensuring the connection of the two pipelines.
