Abstract

A road drilling detection device disclosed by the present invention comprises a rack fixed on a vehicle, the rack is in shaft connection with a supporting arm through a rotating motor, two ends of the supporting arm are respectively provided with a clamp holder, a coring drill cylinder is installed in the clamp holder, the top of the coring drill cylinder is in threaded connection with a top plate, and the center of the top plate is provided with a first connecting hole. A plurality of second connecting holes are evenly formed in the edge of the top of the coring drill barrel, an inner core barrel is inserted into the coring drill barrel, a positioning bolt fixedly connected with the inner core barrel is arranged on the side wall of the coring drill barrel, the inner core barrel comprises two barrel wall assemblies hinged together, and a mounting frame is fixed to the top of the rack; the end, facing the inner side of the vehicle, of the mounting frame is provided with a coring motor through a coring oil cylinder, and the end, facing the outer side of the vehicle, of the mounting frame is provided with a drilling motor through a drilling oil cylinder. The defects in the prior art can be overcome, a sample can be taken out conveniently, drilling coring and sample taking are carried out at the same time, and the sampling period is shortened to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of road detection, in particular to a road drilling detection device. Background technique [0002] Road drilling and coring detection is a common method used to detect parameters such as the thickness and strength of pavement structural layers. In order to facilitate fast coring operations on the road to be tested, many coring devices are installed on the work vehicle to facilitate the transfer of the coring devices. However, the existing vehicle-mounted coring device cannot conveniently and quickly remove the sample from the coring barrel after drilling and coring, resulting in a long sampling cycle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a road drilling detection device, which can solve the deficiencies of the prior art, facilitate sample extraction, realize drilling coring and sample extraction at the same time, and shorten the samp...
