Description

Technical Field

[0001] The utility model relates to the technical field of down-the-hole drills, in particular to a down-the-hole drill which is easy to position. Background Art

[0002] A drilling rig is a construction equipment, mainly used for pile foundation construction of buildings. At present, for buildings such as bridges or high-rise buildings, deeper pile foundations are required to ensure that the safety needs of the building are met. Therefore, for the pile foundation construction of such buildings, a deep hole drilling rig is generally required. During construction, first, a deep hole drilling rig is used to drill holes intermittently, and after drilling a certain depth, the mud and rocks generated during drilling are discharged, and then drilling is continued until the designed depth is reached; then, the outer protective steel cylinder of the pile foundation is placed; finally, the steel cage is placed, and after grouting, the construction of the pile foundation is completed.

[0003] The existing down-the-hole drilling rig generally includes a base, a drilling rig fixing frame, a hydraulic drill rod and other parts. The drill bit rotates and drills, and the hydraulic mechanism is used to control the up and down movement of the drill rod. At the same time, the existing deep hole drilling rig is also equipped with a lifting mechanism for lifting the protective steel cylinder and the steel cage. However, the existing down-the-hole drilling rig equipment lacks an installation positioning device. When the protective steel cylinder is lifted, it is generally necessary to manually use a positioning detection device to detect whether the lifting is offset, and manually use tools to correct the offset. Not only is the efficiency low, but the accuracy is completely dependent on the experience and technical level of the construction personnel. Now a down-the-hole drilling rig that is easy to position is needed to solve the above technical problems. Utility Model Content
