Coring drill and coring machine suitable for asphalt pavement

Abstract

The invention discloses a coring drill and a coring machine suitable for an asphalt pavement, and relates to the field of coring drills, the coring drill comprises a fixed bottom box, transmission shaft rods are symmetrically inserted into the two side edges of the fixed bottom box, rolling wheel bodies fixedly sleeve the outer side edges of the transmission shaft rods, and supporting side plates are vertically welded to the side edges of the fixed bottom box; a fixed top plate is horizontally welded to the side edges between the supporting side plates, a fixed bottom plate is horizontally welded to the side edges between the supporting side plates, an extending through hole is horizontally formed in the top face of the fixed bottom plate, side limiting grooves are symmetrically formed in the side edges between the supporting side plates, a guide column body is vertically and downwards welded to the bottom face of the fixed top plate, and a movable flat plate is horizontally arranged on the side edge between the supporting side plates. The machine is designed to be of an integrated structure, the structure is simple, operation is convenient, the balance weight and movement integrated design is adopted, so that the device is more stable, reliable and convenient to carry, and meanwhile, a detachable connecting structure is adopted, so that maintenance is more convenient.

Description

technical field [0001] The invention relates to the technical field of coring drills, in particular to a coring drill and a coring machine suitable for asphalt pavement. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. For asphalt pavement, it is necessary to use a core drill to operate. [0003] For the current core drills, the side movement is used for drilling, so that when the asphalt road surface is relatively hard, the center of gravity will be unstable and lift or tilt, causing certain injuries to personnel and at the same time It is impossible to drill holes on the ground, which is not conducive to the needs o...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of coring drill and coring machine suitable for asphalt pavement, to solve the above-mentioned background technology, for the present coring drill is to adopt the mode of side movement for drilling, so that in the When the asphalt pavement is relatively hard, the center of gravity will be unstable and lift or tilt, which will cause certain injuries to personnel and cannot drill holes on the ground, which is not conducive to the needs of current social development. At the same time, the volume is large Large-scale machinery is required for auxiliary operations during transportation, which makes it cumbersome and time-consuming to use, and the fixed structural design brings certain troublesome problems in later maintenance.
