Description

Technical Field

[0001] The utility model relates to the technical field of rescue drilling rigs, in particular to a pitch drilling type rescue drilling rig. Background Art

[0002] A rescue drill is a large rescue equipment used to quickly open rescue escape passages after a building collapses. According to the type of escape passage, the rescue drill can be divided into horizontal and vertical types. The horizontal rescue drill mainly constructs horizontal holes in front of the collapsed surface to open horizontal escape passages, while the vertical rescue drill mainly constructs vertical holes above the collapsed surface to open vertical escape passages. Among them, the horizontal rescue drill can quickly approach the collapsed surface, with high tunnel penetration accuracy and short drilling time; while the vertical rescue drill is constructed above the collapsed surface, is almost unaffected by the terrain and tunnel size, and has strong adaptability. However, due to the long distance between the ground and the top of the collapsed surface, the tunnel penetration accuracy is poor and the drilling time is long; therefore, in order to meet the rescue requirements, the horizontal rescue drill is usually preferred for construction and rescue.

[0003] Since horizontal rescue drilling rigs cannot be tilted for construction, when the collapse surface is in an inclined tunnel, it is often impossible to complete accurate tunnel penetration due to large terrain restrictions. Although Chinese utility model patent CN216788286U discloses a horizontal directional drilling rig with good protective performance, the height of the horizontal directional drilling rig body can be adjusted through a height adjustment component, and the buffer mechanism makes the horizontal directional drilling rig body more stable when it is raised or lowered. Then, the angle of the stabilizer bar is adjusted through the support component to facilitate adjustment to the optimal support point to support the horizontal directional drilling rig body, so as to improve the terrain adaptability of the drilling rig by adjusting the pitch angle.

[0004] However, due to the large drilling force, torque and drilling range of the rescue drill, although the above-mentioned horizontal directional drilling rig can adjust the pitch angle, its supporting structure has poor adjustment flexibility and relatively low reliability, which leads to unstable drilling work and affects the accuracy of tunnel penetration.
