Problems solved by technology
[0003] Existing road drilling rigs only have one drill bit to drill holes. In order to meet the hole position of the pre-designed layout: a point must be fixed first, based on a hole, and then the remaining points are measured based on this point, and then drilled one by one to exit the hole. very inefficient

The invention discloses a three-hole array pitch drill machine which comprises three drilling devices. The three drilling devices are installed at the front end of a frame and face forwards, leftwards and rightwards respectively. Each drilling device comprises a rotating impactor, a lifting guide rail, a lifting motor, a lifting oil cylinder, a left and right guide rail and a front and back adjusting oil cylinder. The rotating impactor conducts hole drilling work when the lifting motor moves up and down on the lifting guide rail. The back of the lifting guide rail is hinged to the lifting oil cylinder. The other end of the lifting oil cylinder is fixed to the frame. The lifting guide rail and the rotating impactor integrally make contact with or get away from the ground through the lifting oil cylinder. The left and right guide rail is arranged on the back of the lifting guide rail. The lifting guide rail moves forwards and backwards on the left and right guide rail through the front and back adjusting oil cylinder. Three holes are drilled at the same time at present, and the hole forming efficiency is greatly improved; array pitch is rapid and accurate; after holes are formed, slurry is evenly poured to form an integral net, and the overall bearing performance is good.
Description
technical field [0001] The invention relates to a drilling machine for road surfaces, in particular to a three-hole drilling machine. Background technique [0002] At present, there are more and more concrete roads and asphalt roads. Due to the overload of vehicles and local subsidence of the roadbed, many concrete and asphalt roads will have defects of different sizes. If they are not repaired in time, the defects will become larger and larger , not only make it difficult for the car to drive, but also accelerate the damage of the road surface. According to the previous method of repairing, the damaged area has become an isolated island due to its small area. The unit area is subjected to huge impact and pressure from the car, and the repaired defect will be damaged again in a short time. Therefore, the method that adopts now is to remove the defective concrete highway pavement with machinery earlier, on the exposed defective pavement subgrade 6, press the hole position of...
