Detailed Description
In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. In addition, the features of the embodiments and examples in the present application may be combined with each other without conflict.
The utility model relates to a concrete core drilling machine that typical embodiment provided, including base 1, stand 2, slide 3 and roof 5, two stands 2 are vertical to be fixed at the both ends of base 1, the both ends of slide 3 are equipped with sliding sleeve 4 respectively, sliding sleeve 4 and stand 2 sliding connection, roof 5 upper portion is installed and is fed handle 6, feed handle 6 lower extreme is connected as the lead screw 7 of output shaft, lead screw 7 and slide 3 middle part threaded connection; the drill bit 8 is arranged at the front end of the sliding seat 3; a strip-shaped graduated scale 9 parallel to the upright post 2 is longitudinally arranged on the base 1.
The gasoline engine drives the drill bit to partially rotate, the feed handle 6 is rotated to drive the screw 7 to rotate, the upright post 2 limits the sliding seat 3, and the sliding seat 3 drives the drill bit 8 to move downwards to drill a rock core.
When the water pump works, the drill bit 8 is installed, the gasoline engine is started, the water inlet pipe is placed into the bucket, the bucket is lifted to a position higher than the water pump, then the air bag is pinched by hands to suck water into the water pump, and the bucket is placed on the ground after the water pump supplies water. The throttle is adjusted to the maximum, and the feed handle 6 is started to be slightly shaken, so that the drill bit 8 is slowly contacted with the ground. After the drill bit 8 has contacted the ground, the datum point on the carriage is recorded corresponding to the reading a of the scale.
When the hole is drilled 2-3 mm deep, the drilling can be shifted to normal drilling, the feeding pressure is properly increased, the feeding pressure is moderate and uniform during normal drilling, and the feeding pressure is reduced when the hole touches a thick steel bar. The method is to listen to the water by one person and two persons, to see whether the sound of the machine is normal or not and to see whether the water returns (overflows) from the hole opening or not.
