Description

Technical Field

[0001] The utility model relates to the field of pipeline construction, in particular to a trench excavation device for natural gas transmission pipeline construction. Background Art

[0002] At present, a Chinese utility model with announcement number CN220747055U discloses a trench excavation equipment. In view of the existing problems, the following scheme is proposed, which includes a base plate, legs are fixedly installed at the four corners of the bottom of the base plate, and wheels are rotatably installed at the bottom ends of the four legs, a through hole is opened on the top side of the base plate, vertical plates are fixedly installed on both sides of the top of the base plate, and a handle is slidably installed on the side where the two vertical plates are close to each other, a vertical hole is opened on the top side of the handle, a motor is fixedly installed on the top side of the handle, and a rotating rod is fixedly installed on the output shaft of the motor, and a spiral blade is fixedly sleeved on the rotating rod. The utility model solves the shortcomings of the prior art, so that people can realize the fixing of the moving position of the base plate, thereby facilitating digging and ensuring that there will be no position deviation during the digging process, thereby meeting people's needs.

[0003] Existing trench excavation devices cannot adjust the excavation width. Generally, the size of the digging head of the excavation device is fixed, resulting in a fixed width of the excavated trench. If trenches of different widths need to be excavated, multiple round trips are required to expand the trench to the required width, which is not only labor-intensive but also inefficient and increases construction costs. It is also inconvenient to replace the digging head. Generally, the digging head is fixed and installed by bolts and a rotating shaft. When replacing the digging head, tools are required to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the efficiency of replacement. In order to solve the above-mentioned problems, we propose a trench excavation device for natural gas pipeline construction. Utility Model Content
