Reinforced high holding power anchor shaft

Abstract

The invention discloses a reinforced high holding power anchor shaft which is of a symmetrical frame structure with the vertical axis as the symmetric axis. The reinforced high holding power anchor shaft comprises a left side plate, a right side plate and transverse ribs, wherein the left side plate and the right side plate are connected through the transverse ribs, the lower end of the left side plate and the lower end of the right side plate are respectively provided with a notch facing outwards, pin holes are formed above the notches, three positioning holes which are formed below each notch are distributed in an arc with the corresponding pin hole as the center, and the transverse ribs are parallel to the connection lines between the centers of the pin holes above the notches in the left side plate and the right side plate and the centers of the leftmost positioning holes below the notches; transverse ribs in another direction are further arranged on the left side plate and the right side plate, and the transverse ribs are parallel to the connection lines between the centers of the pin holes above the notches in the left side plate and the right side plate and the centers of the rightmost positioning holes below the notches. According to the reinforced high holding power anchor shaft, due to the fact that the transverse ribs in the two directions are arranged, the bearing capacities of the high holding power anchor shaft when the high holding power anchor shaft works at three different angles are almost the same, the strength of the high holding power anchor shaft is improved, and positioning requirements of different geological sea floors are met.

Description

technical field [0001] The present invention relates to an anchor structure, more specifically, relates to an anchor structure with a large grasping force. Background technique [0002] The anchor shaft with high holding power is a frame-shaped structure with a symmetrical structure on the vertical axis, including a left side plate, a right side plate, and a transverse rib. The left side plate and the right side plate are connected through the transverse rib; The lower end of the plate is provided with an outward notch, the upper part of the notch is provided with a pin hole, and the three positioning holes on the lower part are distributed on the arc centered on the pin hole; The center of the pin hole is parallel to the line connecting the center of the leftmost positioning hole on the lower edge of the notch. The three positioning holes on the lower side of the left side plate and the right side plate can form three working angles for the large holding force anchor, whic...

Problems solved by technology

The transverse rib also bears a certain tensile force when the high-grasp anchor works. Since the anchor stem of the high-grasp anchor in the prior art has three working angles, the transverse rib is at different angles when the high-grasp anchor works, so that the high-grasp anchor The bearing capacity of the anchor stem at the three working angles is different. When using the leftmost positioning hole under the notch, it is the largest, followed by the middle one, and the rightmost one is the smallest, which may affect the normal operation of the large holding force anchor on the seabed. position
