[0002] With the implementation of the national rural revitalization strategy, the complexity of the terrain of villages across the country has brought great challenges to the construction of pipeline projects. Due to the limitations of local areas, traditional excavation cannot meet the construction needs, so directional drilling and horizontal pipe dragging are required for construction. However, during the directional drilling and horizontal pipe dragging construction process, there is a problem of large pipe dragging bending angle, which directly affects the quality of pipe dragging construction and thus affects the construction progress. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model provides a directional drilling horizontal drag pipe curvature straightener. Through its structural design, when in use, a connecting rod is installed at the downward position of the reaming direction and connected to the reamer. By welding, after the connecting rod is fixed, the size of the sleeve plate is adjusted according to the size of the reamer. The construction personnel pull the handle toward the outside of the top tube. The movement of the handle separates the connecting rack from the fixed rack. At this time, the handle is moved toward the support plate again. The movement of the handle drives the top tube to slide on the connecting rod. The sliding of the top tube pushes the slide plate to slide upward in the support plate through the connecting rod, thereby driving the sleeve plate to move outward. When the outer diameter of the sleeve plate is consistent with the outer diameter of the reamer, the handle is released, and the spring drives the handle to reset. The reset of the handle drives the connecting rack to engage with the fixed rack, and the top tube is limited, thereby completing the adjustment of the outer diameter size of the sleeve plate. When the outer diameter size of the sleeve plate is adjusted to be consistent with the outer diameter size of the reamer, construction can be started. Compared with the prior art, the utility model can be widely used in construction operations under various geological conditions, reducing damage to pipelines, thereby saving costs, minimizing the impact on the surrounding environment, and improving work efficiency.
