Description

Technical Field

[0001] The utility model relates to the technical field of ship anchor testing, in particular to a ship anchor gripping force testing device. Background Art

[0002] Anchors are important equipment used to stabilize ships when they are moored. When a ship needs to moor, the anchor is thrown into the water. Its grip can ensure that the ship remains in the predetermined area under the influence of external forces such as wind, waves, and currents, and prevent the ship from colliding with other ships or shore facilities due to drift. At present, in order to ensure the safety and stability of ships when moored, it is necessary to conduct grip tests on anchors.

[0003] For example, the Chinese patent No. 201921309571.8 discloses a ship anchor seabed geological gripping device, including a base plate, a sand geological box is fixedly connected to the left side of the top of the base plate, a winch device is arranged on the front side of the right side of the top of the base plate, a lifting and adjusting support rod is fixedly connected to the right side of the top of the base plate, and a guide device is arranged at the bottom of the inner side of the lifting and adjusting support rod.

[0004] In actual situations, when an anchor is inserted into the seabed sand, the ship will deflect at a certain angle under the action of water flow, wind force, etc., thereby driving the anchor to deflect. However, most of the anchor grip test devices in the prior art have simple structures. When performing a grip test on an anchor, the anchor can only be pulled from a single direction for grip test, which reduces the accuracy of the anchor grip test. Therefore, in view of the above technical problems, a ship anchor grip test device is proposed. Utility Model Content
