Adjustable drilling and coring machine for road construction

Abstract

The invention relates to the technical field of road construction machinery, in particular to an adjustable drilling and coring machine for road construction. Upper ends of lifting devices are provided with a supporting plate. The middle of the upper side of the supporting plate is provided with a first motor. The output end of the first motor is provided with a rotating shaft through a coupling.The lower end of the rotating shaft is connected with a drilling structure. The left side and the right side of the lower side of the supporting plate are symmetrically provided with installation plates. The inner sides of the installation plates are provided with damping devices. Each damping device comprises extensible and retractable rods which are symmetrically arranged on the corresponding installation plate up and down. The outer end of each extensible and retractable rod is provided with a connecting base, and the outer side of each extensible and retractable rod is provided with a damping spring. One end of each damping spring is connected with the corresponding connecting base, and the other end of each damping spring is connected with the corresponding installation plate. Each connecting base is provided with a supporting rod, the outer end of each supporting rod is provided with a clamping plate, and each clamping plate and the rotating shaft are arranged in a sliding manner. The adjustable drilling and coring machine for road construction is simple in structure and convenient to use, the rotating shaft can be protected, the probability of breakage of the rotating shaftis reduced, and normal proceeding of the work is guaranteed.

Description

technical field [0001] The invention relates to the technical field of road construction machinery, in particular to an adjustable drilling corer for road construction. Background technique [0002] Road engineering refers to the whole process of planning, design, construction, maintenance and management of roads and the engineering entities involved. Like any other category of civil engineering, road engineering has obvious technical, economic and management characteristics. The drilling rig is powered by a gasoline engine, which is beautiful in appearance, durable, easy to start, reliable in operation and easy to operate. Diamond thin-wall drill bits are suitable for drilling concrete, cement, asphalt pavement and rocks, and can be equipped with an electric ignition device.

Problems solved by technology

[0003] Chinese patent (authorized announcement number: CN 207487995 U) discloses a municipal road surface drilling and coring machine, which can realize the movement of the internal drill bit of the fixed frame by setting the handle, which increases the adjustability. The work of the first water storage tank makes the first water delivery pipe cool down, so that the water in the first water delivery pipe passes through the triangular inclined block to cool the outer surface of the drill bit, and then the second water delivery pipe is cooled by the work of the second water storage tank. The water in the second water pipe passes through the upper surface of the drill bit to cool the inside of the drill bit, which increases the overall cooling effect, makes the drilling and coring machine work more stably, and avoids high temperature generation, but the length of the rotating shaft is now longer , there is no corresponding buffer device. When working, the vibration generated by the device will cause a bias force on the rotating shaft, making the rotating shaft easy to break and affecting normal work.
