Description

Technical Field

[0001] This utility model relates to the field of highway testing equipment, and in particular to a core sampling device for highway testing. Background Technology

[0002] Highway inspection is an important means of ensuring highway safety, comfort and durability. In order to clearly understand the quality of the highway, core sampling equipment is needed for core sampling inspection.

[0003] Existing coring equipment consists of a mobile frame, a lifting mechanism, and a coring mechanism. After moving the device to the coring location via the mobile frame, the coring device is activated for drilling and coring, while the lifting mechanism is controlled for vertical coring. The existing mobile frame of this type of equipment is moved using casters and swivel casters. After the device is in place, the swivel casters are folded down so that one end of the support touches the ground, and then drilling and coring are performed directly. This coring operation means that the end of the mobile support with the casters cannot be adjusted, making the device unstable during coring. Therefore, this solution proposes a new coring device for highway inspection to address the above problems. Utility Model Content
