Drilling and coring machine for highway pavement detection

Abstract

The invention discloses a drilling and coring machine for highway pavement detection, and relates to the field of drilling and coring machines. The drilling and coring machine comprises a fixed bottom plate, rolling wheels are arranged on the bottom face of the fixed bottom plate, a top fixing groove is horizontally formed in the top face of the fixed bottom plate, and a fixed disc is in threaded connection with the inner side edge of the top fixing groove; supporting vertical rods are vertically and upwards welded to the top face of the fixed disc, a movable top disc is horizontally arranged on the side edge between the supporting vertical rods, a drilling motor is connected to the bottom face of the movable top disc through bolts, the output end of the drilling motor is fixedly sleeved with a drilling column, and a fixed top plate is horizontally welded to the top ends of the supporting vertical rods. The top face of the fixed top plate is in bolt connection with a pushing and pressing air cylinder. According to the device, the split structure is designed, installation is easy and convenient through threaded connection, meanwhile, operation is easy, convenient and rapid through an intelligent automatic moving structure, drilling is rapid and efficient during electric operation, and the drilling efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of drilling and coring machines, in particular to a drilling and coring machine for highway pavement detection. Background technique [0002] Concrete drilling and coring machine mainly has two purposes, one is for horizontal drilling, it is suitable for road stud installation, road pile installation, bridge drilling operation rules, integrated house pile foundation drilling, etc. It has been widely used in traffic engineering companies , China Railway Group, Integrated Housing Company and other units; the second is for coring, which is suitable for road coring for testing and has been widely used in testing centers around the world. The drilling rig is powered by a Honda gasoline engine. It is beautiful in appearance, durable, easy to start, reliable in operation, and easy to operate. Electric ignition device can be configured. Maximum drilling and coring diameter: ∮200mm Maximum drilling and coring depth...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of drilling coring machine for highway pavement detection, to solve the above-mentioned background technology for the present drilling and coring machine adopting is the unilateral operation setting, because when the ground is drilled There will be situations where the support is not in place, so that the downforce of the drilling hole is small and the progress of the drilling is affected. At the same time, when the soil layer of the drilling hole is taken out and tested, it is still necessary to operate the whole machine upside down, which makes it time-consuming and laborious. Problems that are detrimental to current detection operations
