WIPO Patent Application WO/2023/113221
Kind Code:

Abstract:
Disclosed is a penetration roller for a cone penetration test device having a structure for assessing a replacement time and preventing a slip. A penetration roller for a cone penetration test device having a structure for assessing a replacement time and preventing a slip according to the present invention comprises: a frame seated on a seabed surface; a support body coupled to the frame; and a pair of first and second penetration rollers provided inside the support body so as to be rotated by a driving member provided on the support body in a direction such that same engage with each other, thereby pressurizing both sides of the outer peripheral surface of a rod having a cone probe coupled to an end thereof. As the first and second penetration rollers rotate in the forward or backward direction, the cone is made to penetrate a seabed foundation or is recovered. The first and second penetration rollers have concave pressurizing surfaces formed on outer peripheral surfaces thereof with the same curvature as the outer peripheral surface of the rod. Anti-slip protrusions are successively formed on the concave pressurizing surfaces such that, when the rod is pressurized and thus moved upwards or downwards, same penetrate the outer peripheral surface of the rod while forming stamping grooves thereon, thereby preventing a slip, and it is recognized whether the pressurizing surfaces are worn or not on the basis of the depth of the stamping grooves formed on the outer peripheral surface of the rod, thereby confirming whether or not to replace the first and second penetration rollers.
