DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of protection of the utility model.

[0021] One embodiment provided by the utility model: as Figure 1 The utility model discloses a deep water pile foundation positioning device, which comprises a positioning seat 1, a fixed connecting piece 2, a pile foundation auxiliary mechanism 3 and a pile foundation 4.

[0022] Before installing the pile foundation 4 in deep water, the positioning seat 1 is fixed at the position to be positioned of the underwater pile foundation 4 through the fixed connecting piece 2.

[0023] As shown in Figure 1 The positioning seat 1 is provided with a slot hole 101 in the center, the inner diameter of the slot hole 101 is matched with the outer diameter of the pile foundation 4, and the bottom of the pile foundation 4 is positioned in the inner side of the slot hole 101 of the positioning seat 1 through the hoisting equipment.

[0024] As shown in Figure 1 And Figure 2 The pile foundation auxiliary mechanism 3 is arranged in multiple groups and is annularly distributed around the slot hole 101 of the positioning seat 1, one end of the pile foundation auxiliary mechanism 3 is hingedly connected with the positioning seat 1, the one end of the pile foundation auxiliary mechanism 3 is provided with a connecting shaft 31, and the pile foundation auxiliary mechanism 3 is hingedly connected in the recess of the pile foundation auxiliary mechanism connecting piece 11 above the positioning seat 1 through the connecting shaft 31.

[0025] As shown in Figure 3As shown, the pile foundation auxiliary mechanism 3 is vertically arranged on one side of the positioning seat 1 away from the center of the positioning seat 1, and is connected to one end of two groups of support assemblies 33, and the other end of the two groups of support assemblies 33 is installed on the protruding piece 12 on the side of the positioning seat 1. The length of the upper group of support assemblies 33 is greater than the length of the lower group of support assemblies 33. Each group of support assemblies 33 comprises two groups of connecting seats 331 and one group of support rods 332, and the two ends of the support rod 332 are respectively hinged to the connecting seat 331. The upper group of connecting seats 331 is fixedly connected to the support assembly 33, and the lower group of connecting seats 331 is fixedly connected to the protruding piece 12.

[0026] By selecting different support assemblies 33 for connection and fixation, the pile foundation auxiliary mechanism 3 can have two states.

[0027] As shown in the drawings, Figure 1 One case is that before the pile foundation 4 is installed, the lower connecting seat 331 of the shorter group of support assemblies 33 is fixed to the protruding piece 12, and at this time, all the pile foundation auxiliary mechanisms 3 are rotated around the connecting shaft 31 to an inclined state relative to the positioning seat 1, and the top of the combination of all the pile foundation auxiliary mechanisms 3 is in an open state. Since the top of the combination of all the pile foundation auxiliary mechanisms 3 has a larger circle than the bottom, that is, a larger inner diameter than the inner diameter of the slot hole 101, compared with the installation operation of directly positioning the bottom of the pile foundation 4 in the slot hole 101, the pile foundation 4 can first contact the upper inclined surface of the combination of the pile foundation auxiliary mechanisms 3 and finally fall into the slot hole 101 along the inclined surface. The open part of the pile foundation auxiliary mechanism 3 increases the area and improves the opportunity of the pile foundation 4 to smoothly enter the slot hole 101, thereby increasing the efficiency of the installation and positioning of the pile foundation 4 to the positioning seat 1.

[0028] As shown in the drawings, Figure 4 Another case is that after the pile foundation 4 is installed and positioned in the slot hole 101 of the positioning seat 1, the lower connecting seat 331 of the longer group of support assemblies 33 is fixed to the protruding piece 12, and at this time, all the pile foundation auxiliary mechanisms 3 are rotated around the connecting shaft 31 to a vertical state relative to the upper surface of the positioning seat 1. The side of the pile foundation auxiliary mechanism 3 close to the center of the positioning seat 1 is an arc surface, and the inner diameter around the combination of the plurality of pile foundation auxiliary mechanisms 3 matches the outer diameter of the pile foundation 4 and the inner diameter of the slot hole 101 of the positioning seat 1. Under the support of the longer group of support assemblies 33, all the pile foundation auxiliary mechanisms 3 press and fix the circumferential side of the pile foundation 4, support and limit the bottom of the pile foundation 4 from multiple angles, keep the pile foundation 4 vertical, and avoid the water flow from causing the bottom of the pile foundation 4 to be inclined, thereby improving the stability of the pile foundation 4 itself.

[0029] The pile foundation auxiliary mechanism 3 on the side of the positioning seat 1 can not only assist in positioning and installing the pile foundation 4 to the accurate position underwater, but also limit and fix the bottom of the pile foundation 4.

[0031] When the pile foundation 4 is installed, the lower connecting seat 331 of the shorter group of supporting assemblies 33 is fixed to the convex piece 12, the top of all the pile foundation auxiliary mechanisms 3 is in an open state, the two groups of sliding assemblies 32 on all the pile foundation auxiliary mechanisms 3 are adjusted, the rotating rod 322 is rotated relative to the fixed seat 321, the side of the rotating rod 322 with the roller 3221 is rotated to the side in contact with the pile foundation 4, at this time, the outer edge of the roller 3221 protrudes from the pile foundation auxiliary mechanism 3, when the pile foundation 4 falls in the area combined by the pile foundation auxiliary mechanisms 3, the roller 3221 contacted by the bottom edge of the pile foundation 4 is continuously rotated in the process of the pile foundation 4 continuing to fall, the pile foundation 4 is quickly installed into the slot hole 101 of the positioning seat 1, and damage caused by friction between the pile foundation 4 and the pile foundation auxiliary mechanism 3 is reduced.

[0032] When the pile foundation 4 is installed, the lower connecting seat 331 of the shorter group of supporting assemblies 33 is fixed to the convex piece 12, the top of all the pile foundation auxiliary mechanisms 3 is in an open state, the two groups of sliding assemblies 32 on all the pile foundation auxiliary mechanisms 3 are adjusted, the rotating rod 322 is rotated relative to the fixed seat 321, the side of the rotating rod 322 with the roller 3221 is rotated to the side in contact with the pile foundation 4, at this time, the outer edge of the roller 3221 protrudes from the pile foundation auxiliary mechanism 3, when the pile foundation 4 falls in the area combined by the pile foundation auxiliary mechanisms 3, the roller 3221 contacted by the bottom edge of the pile foundation 4 is continuously rotated in the process of the pile foundation 4 continuing to fall, the pile foundation 4 is quickly installed into the slot hole 101 of the positioning seat 1, and damage caused by friction between the pile foundation 4 and the pile foundation auxiliary mechanism 3 is reduced.
