Description

Technical Field

[0001] The utility model relates to the technical field of mooring anchors for offshore oil platforms and wind power platforms, in particular to a deep-sea pile anchor head connection structure. Background Art

[0002] As the exploration of marine resources is increasingly moving towards the deep sea, deep-sea mooring and anchoring solutions have greatly affected the installation efficiency of the mooring system. For geological areas with deep water and soft seabed soil, a gravity-penetrated mooring anchor can be used. Through free fall on the installation ship, the anchor body is driven into the seabed under its own weight, thereby completing rapid mooring. Since this type of anchor mainly relies on gravity to complete mooring and anchoring, the shape and deadweight requirements of its anchor head are relatively high. Conventional anchor heads are extremely difficult to install due to their one-piece casting. Therefore, a new type of structure is needed to ensure that the anchor head has sufficient strength while taking into account the convenience of construction and installation. Summary of the invention

[0003] The utility model aims to solve the above technical problems and provide a deep-sea pile anchor head connection structure, which has the characteristics of convenient production, easy installation, stable structure, etc.

[0004] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by the utility model is: a deep-sea pile anchor head connection structure, characterized in that it includes an anchor body, a cast anchor head, a counterweight block is arranged in the cast anchor head, a connection cover is arranged on the outside of the cast anchor head, and the connection cover is threadedly connected to the anchor body.

[0005] Preferably, the outer circle of the cast anchor head is provided with a first step, the inner circle of the connecting cover is provided with a second step, and the first step cooperates with the second step to limit position.

[0006] Preferably, the end portion of the connecting cover on the connecting side with the anchor body is arranged in a cylindrical shape, the outer circle of the end portion is arranged with an external thread, the end portion of the anchor body is arranged with an internal thread, and the external thread matches the internal thread.

[0007] Preferably, a limiting portion is provided in the anchor body to limit the anchor head and the connecting cover, and the upper end surface of the counterweight block is flush with the upper plane of the limiting portion.

[0008] Compared with the traditional structure, the beneficial effects of the utility model are as follows: the structure is simple, the end of the deep-sea pile anchor is designed as a two-section combined structure, and the connection is completed through the threads on the anchor body and the connecting cover, which not only ensures stable anchoring fixation, but also compared with the integrally cast anchor head, the weight of the connecting cover is lighter, it is easy to operate when tightening the threads, it is convenient to install, and can be mass-produced. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the structure of the utility model;

[0010] In the figure: 1. Anchor body, 11. Limiting part, 2. Connecting cover, 3. Cast anchor head, 4. Counterweight block. DETAILED DESCRIPTION

[0011] The utility model is further described below.

[0012] See attached Figure 1 A deep-sea pile anchor head connection structure, characterized in that it includes an anchor body 1, a cast anchor head 3, a counterweight block 4 is arranged inside the cast anchor head 3, a connection cover 2 is arranged outside the cast anchor head 3, and the connection cover 2 is threadedly connected to the anchor body 1.

[0013] In this preferred embodiment, the outer circumference of the cast anchor head 3 is provided with a first step, and the inner circumference of the connecting cover 2 is provided with a second step, and the first step cooperates with the second step to limit position.

[0014] In this preferred embodiment, the end of the connecting cover 2 connected to the anchor body 1 is set to be cylindrical, and the outer circle of the end is provided with an external thread. The end of the anchor body 1 is provided with an internal thread, and the external thread matches the internal thread.

[0015] In this preferred embodiment, a limiting portion 11 is provided in the anchor body 1 to limit the casting anchor head 3 and the connecting cover 2 , and the upper end surface of the counterweight block 4 is flush with the upper plane of the limiting portion 11 .

[0016] In specific implementation, the counterweight block 4 is embedded in the cast anchor head 3, and then the connection cover 2 is put on the outer side of the cast anchor head 3 from the outer cone side, and connected with the anchor body 1 through threads to complete the installation. Compared with the integrally cast anchor head, the connection cover is lighter in weight, can be easily operated when tightening the threads, is convenient to install, and can be mass-produced.

[0017] The above embodiments of the present invention are merely examples to clearly illustrate the present invention, but are not intended to limit the protection scope of the present invention. All equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
