The invention relates to the field of drilling, in particular to washing drilling equipment for civil construction. The lifting groove is used for enabling the transmission shaft to slide downwards relative to the drilling shell when the rotating speed of the drilling shell is lower than that of the transmission shaft. A friction section is arranged on the peripheral wall of the transmission shaft, the synchronous rotating ring is configured to slide up and down synchronously with the drilling shell, and the synchronous rotating ring is in contact with the friction section in an initial state, so that the transmission shaft drives the synchronous rotating ring to rotate, and the synchronous rotating ring is separated from the friction section when the transmission shaft moves downwards to a preset distance relative to the synchronous rotating ring. The expansion assembly is used for moving upwards along the transmission shaft when the transmission shaft moves downwards to a preset value along the drilling shell. In the initial state, the outer ends of the multiple crushing cutters are located above the inner ends of the multiple crushing cutters, so that when the expansion assembly moves upwards along the transmission shaft, the crushing cutters gradually move to be in the horizontal state, then the multiple crushing cutters crush the corresponding parts, the drilling mechanism drills downwards more easily, and therefore the drilling efficiency is improved.
Description
technical field [0001] The invention relates to the field of drilling, in particular to a water-washing drilling equipment used for civil construction. Background technique [0002] During the drilling process of civil construction, drilling equipment is usually used to break the concrete structure. The places to be drilled in civil construction are generally composed of concrete, so water-washed drilling equipment is generally used for drilling. Generally, the quality of the holes punched, and the length of time it takes are not only related to the characteristics of the concrete structure to be drilled and the performance of the drilling equipment itself, but also to the degree of matching between the drilling equipment and the construction location. Reasonable selection of drilling device plays an important role in increasing the drilling speed and reducing the comprehensive cost of drilling. [0003] The existing drilling equipment for drilling holes in civil constructi...
