These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0057] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0058] In the description of the present application, it should be understood that the terms "counterclockwise", "clockwise", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0059] The clamp-type pile turner is used to lift steel pipe piles during offshore construction. Several hydraulic clamps on the clamp-type pile turner clamp on the top pipe wall of the steel pipe pile and apply a certain pressure, converting the hydraulic pressure into friction between the clamp and the pipe wall, so that the steel pipe pile will not slide due to its own weight during the turning and vertical rotation process, thus realizing the turning and vertical rotation of the steel pipe pile without lifting ears.

[0060] The application of clamp-type pile turning device has effectively solved the problem of cutting off the lifting lug after turning over the steel pipe pile. It has the outstanding characteristics of high construction efficiency, environmental protection and material saving. However, in order to ensure the reliability of the hydraulic clamp, the inner clamp arm is usually the fixed end. In order to reduce the influence of the clamp on the ovality of the pile top, the outer diameter of the clamp arm at the fixed end is generally about 1cm to 2cm smaller than the inner diameter of the top wall of the steel pipe pile; the outer clamp arm of the clamp is the movable end, which is provided with a jacking cylinder connected to the hydraulic system, which can control the extension and contraction and pressurization of the outer clamp arm to achieve the purpose of clamping the steel pipe pile wall.

[0061] The offshore construction environment is complex and changeable. Affected by many external factors such as wind, waves, and surges, crane ships and transport ships will inevitably fluctuate up and down during the operation process. When the fluctuation exceeds a certain level, it is difficult for the pile turner to be installed smoothly on the pile top. Therefore, it is becoming increasingly important to reduce the installation difficulty of the pile turner and improve the installation efficiency.

[0062] The present application provides an installation device for a steel pipe pile clamp-type pile turner, which aims to solve the technical problems of difficult installation and low efficiency of the clamp-type pile turner in offshore operations in the prior art.
