Abstract
The utility model relates to a special stable oil cylinder system for a pile gripper, which comprises a fixed seat (1), wherein a guide seat (2) is arranged inside the fixed seat (1) in a sliding manner along the axial direction of the fixed seat, and an oil cylinder (3) is arranged inside the guide seat (2); the movable end and the fixed end of the oil cylinder (3) are respectively hinged with the guide seat (2) and the fixed seat (3); the outer section shape of the guide seat (2) is consistent with the inner wall section shape of the fixed seat (1) and is rectangular. The pile gripper oil cylinder is simple in structure, stable and reliable in stress state, and the service life of the pile gripper oil cylinder is greatly prolonged.
Description
Technical Field
The utility model relates to a special stable oil cylinder system for a pile gripper, and belongs to the technical field of tools for offshore construction.
Background
Offshore operations such as offshore oil platforms, offshore lighthouse construction and offshore wind power projects all require operations such as offshore pile foundation positioning and guiding, pile sinking and piling, and the operations are generally implemented on corresponding engineering ships or platforms through clamping, positioning and guiding of pile foundations by pile grippers.
Because the influence of sea stormy waves, can form the striking of not equidimension between pile gripper and the pile foundation, friction, rotation, complicated effect relation such as multi-direction atress, under this kind of operating mode, the guide roller hydro-cylinder that traditional pile gripper used, its piston and hydro-cylinder inner wall very easily take place inhomogeneous atress and cause the damage, serious accidents such as oil leak inefficacy or even piston rod fracture form, reduce the life of pile gripper hydro-cylinder by a wide margin, consequently need for a novel hydro-cylinder system that the reliability is high urgently.
Disclosure of Invention
The utility model aims to overcome the defects and provide the special stable oil cylinder system for the pile gripper, which can resist complex stress working conditions, has good reliability and long service life.
The purpose of the utility model is realized as follows:
a special stable oil cylinder system for a pile gripper comprises a fixed seat, wherein a guide seat is arranged in the fixed seat in a sliding manner along the axial direction of the fixed seat, and an oil cylinder is arranged in the guide seat; the movable end and the fixed end of the oil cylinder are respectively hinged with the guide seat and the fixed seat; the outer section shape of the guide seat is consistent with that of the inner wall of the fixed seat and is rectangular.
The utility model relates to a special stable oil cylinder system for a pile gripper.
The utility model relates to a special stable oil cylinder system for a pile gripper.
Compared with the prior art, the utility model has the beneficial effects that:
the pile gripper oil cylinder is simple in structure, and the fixed seat and the guide seat rectangular section sliding fit structure is arranged to offset the acting force in the complex direction, so that the oil cylinder arranged in the guide seat is only subjected to the axial acting force, the working stress condition of the oil cylinder is greatly improved, the oil cylinder works more stably, and the service life of the pile gripper oil cylinder is prolonged.

Wherein:
Detailed Description
Referring to fig. 1 to 3, the special stable oil cylinder system for the pile gripper comprises a fixed seat 1, a guide seat 2 is arranged inside the fixed seat 1 in a sliding manner along the axial direction of the fixed seat, and an oil cylinder 3 is arranged inside the guide seat 2; the movable end and the fixed end of the oil cylinder 3 are respectively hinged with the guide seat 2 and the fixed seat 1; the outer section shape of the guide seat 2 is consistent with that of the inner wall of the fixed seat 1 and is rectangular.
Further, a guide roller 4 is arranged at the end of the guide base 2 in a rolling manner.
Furthermore, the movable end and the fixed end of the oil cylinder 3 are respectively hinged with the guide seat 2 and the fixed seat 1 through pin shafts.
When the pile gripper works, the guide roller 4 is in rolling contact with the pile pipe and transmits acting forces of the pile pipe on the pile gripper in various directions; the guide seat 2 and the fixed seat 1 are of a sliding fit structure with a rectangular cross section, and can only slide axially relatively, so that the structure only transmits axial acting force to the oil cylinder 3, and acting forces in other directions are all borne by the rectangular sliding fit structure, so that the working state of the oil cylinder 3 is only acted by the axial force, the working state of the oil cylinder 3 is improved, and the service life of the oil cylinder 3 is greatly prolonged.
In addition: it should be noted that the above-mentioned embodiment is only a preferred embodiment of the present patent, and any modification or improvement made by those skilled in the art based on the above-mentioned conception is within the protection scope of the present patent.
