Description

Technical Field

[0001] This application relates to the field of pipeline construction, specifically to a device for assisting in pipeline welding and precise placement into trenches. Background Technology

[0002] When pipes welded outside the trench are put into the trench, there is a risk of the pipes breaking. When using truck cranes or excavators to lift the pipes, 3-4 truck cranes and excavators are needed to work together for 60m of pipe. The cost of machinery shifts is high, the coordination of machinery is difficult, and it is easy to damage the already welded pipes.

[0003] In the construction of open-cut water transmission and distribution pipeline projects, there are two options: one is to connect the pipelines in the trench after the trench is excavated, and the other is to carry out the trench excavation and pipeline welding simultaneously, and then place the welded pipelines into the trench in sections.

[0004] Current methods involve welding pipes inside trenches, which is difficult and dangerous, requiring most workers to operate within the trench and increasing the risk of accidents. Furthermore, trench collapses can cause incalculable loss of life and property. Traditional methods involve using truck cranes or excavators to lift the welded pipes into the trench, resulting in significant waste of machinery costs and extended construction time. This invention aims to provide a construction device that precisely delivers welded pipes from outside the trench into the trench. Utility Model Content

[0008] More preferably, the clamp is assembled from two semi-circular rings, with one end of the two semi-circular rings hinged together and the other end bolted together.

[0009] Furthermore, the lifting support includes a platform plate and an electric hydraulic cylinder, with both ends of the electric hydraulic cylinder being hinged to the platform plate and the bottom of the lifting frame, respectively.

These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0021] Example 1

[0022] A device for assisting in pipe welding and precise placement into the groove, such as... Figure 1 and 2 As shown, the device includes several lifting frames 1 spaced apart along the length of the pipe trench, and pipe clamps 2 mounted on the lifting frames 1 for fixing the pipe 3. The lifting frame 1 includes a platform body 11, a lifting support 12 located below the platform body 11 away from the pipe trench, and a hinge support 13 located below the platform body 11 near the pipe trench. The platform body 11 also has a track groove 14 along its length toward the pipe trench. The pipe clamp 2 includes a pipe clamp 21 and a clamping strip 22 arranged around the outer wall of the pipe clamp 21. The clamping strip 22 is limited within the track groove 14 and rolls along the track groove 14. In use, several lifting frames 1 are placed side by side on the side of the trench and set perpendicular to the trench. After a single pipe is segmented and welded to the pipe clamp 21 on the lifting frame 1, the lifting support 12 is slightly lifted at the same time to make the pipe clamp 2 roll to the right. After the pipe clamp is opened, the welded pipe is pushed into the pipe trench. A level can be installed on the lifting frame 1 as needed to facilitate pipe alignment and welding.

[0024] Based on Embodiment 1, the pipe clamp 21 is assembled from two semi-circular rings, with one end of each semi-circular ring hinged together and the other end bolted together. The lifting support 12 includes a platform plate and an electric hydraulic cylinder. The two ends of the electric hydraulic cylinder are respectively hinged to the platform plate and the bottom of the lifting frame 1. The track groove 14 is a C-shaped steel structure. The bottom of the C-shaped steel channel is evenly spaced with several through holes for inserting temporary limiting plugs 4. The temporary limiting plugs 4 play a temporary limiting role when docking and welding pipes. The temporary limiting plugs 4 include a rod 41, and The first clamping plate 42 and the second clamping plate 43 are fixed on the insertion rod 41. The first clamping plate 42 is fitted to the top surface of the two folded edges of the C-shaped steel structure.
