a spud boot

Abstract

The invention discloses a pile shoe, and belongs to the field of lifting platforms. The pile shoe comprises an upper-layer plate, a lower-layer plate, a gear, a screw rod, a lifting oil cylinder, two expansion plates and two guide plates; the expansion plates include side sliding plates and racks; in pile insertion, the lifting oil cylinder controls movement of the screw rod to rotate the gear to drive the two expansion plates to laterally slide outwards so as to stretch out the side slide plates from between the upper-layer plate and the lower-layer plate; and in pile pulling, the lifting oil cylinder controls movement of the screw rod to rotate the gear to drive the two expansion plates to laterally slide inwards so as to retract the side slide plates to between the upper-layer plate and the lower-layer plate, so that the contact area between the pile shoe and silt is reduced, the resistance of the silt to the pile shoe is reduced, a pile leg can be pulled out more easily, pile washing-out equipment is not needed anymore, and the cost is saved.

Description

technical field [0001] The invention relates to the field of lifting platforms, in particular to a spud shoe. Background technique [0002] An offshore platform is a structure that provides production and living facilities for activities such as drilling, oil production, transportation, observation, navigation, and construction at sea. It is mainly composed of a platform part and a supporting part. The supporting part of the offshore platform mainly includes a spud leg and a spud shoe, and the spud shoe is fixed at the bottom end of the spud leg. The spud cans are generally inserted into the sediment on the seabed to bear the pressure of the entire offshore platform. [0003] Since the spud cans are subjected to relatively large pressure for a long time and sediment is deposited for a long time, it is difficult to pull the spud cans out of the mud and sand when the offshore platform needs to move. [0004] At present, in order to facilitate the extraction of the spud boots...

AI Technical Summary

Problems solved by technology

[0003] Because the spud cans have been subjected to high pressure for a long time and the sediment has been deposited for a long time, it is difficult to pull the spud cans out of the sand when the offshore platform needs to be moved.

[0004] At present, in order to facilitate the extraction of the spud boots from the sand, corresponding pile flushing equipment is often installed to wash away the sand around the spud boots by using water flow or air flow. This method not only increases the time for pulling out the piles but also increases the The cost of purchasing related equipment
