Description

Technical Field

[0001] This invention belongs to the field of marine oil engineering technology, and particularly relates to a coaxial measurement and adjustment device for installing riser clamps. Background Technology

[0002] In the installation of riser clamps (especially underwater clamps) on offshore platforms, it is essential to accurately position the clamps to ensure that the installation angle meets the riser design requirements. Traditional positioning methods using simple structures such as scaffolding pipes and square tubes have the following core problems: (1) Large positioning error: The instability of simple structures makes it easy for the installation angle of the riser clamp to deviate from the design position; (2) Adjustment reference failure: When the measuring wire hanging point is fixed, the hanging point cannot provide an effective adjustment reference when the riser clamp is offset by a large angle or needs to pass through the anode. (3) Construction interference risk: The traditional measuring rod has a fixed length, which is prone to interference with the subsequent chain hoist, riser clamp travel route and jacket structure, affecting construction efficiency and safety.

[0003] Therefore, there is an urgent need to design a coaxial measuring and adjusting device for installing riser clamps to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a coaxial measuring and adjusting device for installing riser clamps, which has the advantages of precise positioning, flexible adjustment and interference-free construction for installing riser clamps, and solves the problem of inaccurate measurement of riser clamp position in the prior art.

[0005] To achieve the above objectives, the specific technical solution of the coaxial measuring and adjusting device for installing riser clamps of the present invention is as follows: A coaxial measuring and adjusting device for installing riser clamps includes a main track mechanism, which is positioned above the riser clamps. One end of the main track mechanism is rotatably connected to a frame, and the other end of the main track mechanism, away from the frame, is connected to a pile leg via a rotation avoidance mechanism. An adjusting mechanism is slidably mounted on the main track mechanism, and a measuring steel wire is connected to the adjusting mechanism. The measuring steel wire is lowered along the center of the riser clamps to measure the center positions of multiple riser clamps, ensuring that the centers of the multiple riser clamps are aligned in a straight line.

[0006] Furthermore, the main track mechanism includes a first angle steel and a second angle steel, with the second angle steel connected to the first angle steel, so that the adjusting mechanism can move along the length of the first and second angle steels.

[0007] Furthermore, the first and second angle steels are connected to the frame via a pivot.

[0008] Furthermore, the first angle steel and the second angle steel are of the same length.

[0009] Furthermore, the adjustment mechanism is equipped with a positioning slider, which is aligned with either the first angle steel or the second angle steel to fix the position of the adjustment mechanism.

[0010] Furthermore, the adjustment mechanism is equipped with a wire hanging point so that the measuring wire can be connected to the wire hanging point.

[0011] Furthermore, the rotating avoidance mechanism includes a first connecting plate and a second connecting plate, with the second connecting plate connected to the first connecting plate via a positioning rotating shaft.

[0012] Furthermore, the first connecting plate is connected to the pile leg, and the second connecting plate is connected to the first angle steel and the second angle steel. Rotating the second connecting plate allows the first angle steel and the second angle steel to rotate around the pile leg.

[0013] Furthermore, both the first and second connecting plates are provided with multiple openings, and detachable positioning pins are inserted into the corresponding openings to fix the second connecting plate to the first connecting plate.

[0014] Furthermore, a limiting block is provided on the first connecting plate, which limits the movement of the second connecting plate.

[0015] The coaxial measuring and adjusting device for installing riser clamps of the present invention has the following advantages: (1) The present invention improves the positioning accuracy: by cooperating with the main track mechanism through the movable adjustment mechanism, the measuring steel wire and the center line of the riser clamp are accurately aligned, reducing the installation angle error.

[0016] (2) The present invention enhances the flexibility of adjustment: the sliding adjustment mechanism is designed to adapt to the large-angle rotation of the riser clamp and the anode penetration scenario, ensuring that the reference function is effective during the adjustment process.

[0017] (3) The present invention avoids construction interference: the rotating avoidance mechanism can avoid the travel path of pile legs, chain hoists and riser clamps by rotating, ensuring smooth construction. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0022] The following is a reference to the appendix. Figure 1 The present invention describes a riser clamp mounting coaxial measuring and adjusting device.

[0023] like Figure 1 As shown, the coaxial measurement and adjustment device for installing riser clamps in this invention includes a main track mechanism 1, which is positioned above the riser clamp. One end of the main track mechanism 1 is rotatably connected to a frame, and the other end of the main track mechanism 1, away from the frame, is connected to the pile leg via a rotation avoidance mechanism 3. An adjustment mechanism 2 is slidably mounted on the main track mechanism 1, and a measuring steel wire is connected to the adjustment mechanism 2. The measuring steel wire is lowered along the center of the riser clamp to measure the center position of multiple riser clamps, so that the centers of multiple riser clamps are aligned in a straight line.

[0024] The movable adjustment mechanism 2 works in conjunction with the main track mechanism 1 to achieve precise alignment between the measuring steel wire and the center line of the riser clamp, reducing installation angle errors. At the same time, the rotation avoidance mechanism 3 can rotate to avoid the movement of the pile legs, chain hoists, and riser clamps, ensuring smooth construction.

[0025] Furthermore, such as Figure 1 As shown, the main track mechanism 1 includes a first angle steel 11 and a second angle steel 12. The second angle steel 12 is fixedly connected to the first angle steel 11, that is, the first angle steel 11 and the second angle steel 12 are connected along the length direction so that the adjustment mechanism 2 can move along the length direction of the first angle steel 11 and the second angle steel 12.

[0026] The first angle steel 11 and the second angle steel 12 are connected to the frame by a pivot, so that the first angle steel 11 and the second angle steel 12 can move horizontally around the frame above the riser clamp. Preferably, the first angle steel 11 and the second angle steel 12 have the same length.

[0027] Furthermore, such as Figure 1As shown, the adjusting mechanism 2 is equipped with a positioning slider, which is connected to the first angle steel 11 or the second angle steel 12 to fix the position of the adjusting mechanism 2 and prevent the adjusting mechanism from falling off.

[0028] Preferably, the adjustment mechanism 2 is composed of multiple welded steel plates. The adjustment mechanism 2 is sleeved on the first angle steel 11 and the second angle steel 12 so that the adjustment mechanism 2 can move along the length direction of the first angle steel 11 and the second angle steel 12. A wire hanging point 21 is provided at the center position of the adjustment mechanism 2 so that the measuring wire is connected to the wire hanging point 21.

[0029] Furthermore, such as Figure 1 As shown, the rotating avoidance mechanism 3 includes a first connecting plate 31 and a second connecting plate 32. The second connecting plate 32 is connected to the first connecting plate 31 through a positioning rotating shaft 33, thereby causing the second connecting plate 32 to rotate relative to the first connecting plate 31.

[0030] The first connecting plate 31 is vertically welded to the pile leg, and the second connecting plate 32 is connected to the first angle steel 11 and the second angle steel 12. When the second connecting plate 32 is rotated, the first angle steel 11 and the second angle steel 12 move around the pile leg.

[0031] The first connecting plate 31 and the second connecting plate 32 are each provided with multiple openings. A detachable positioning pin 34 is inserted into the corresponding opening to fix the second connecting plate 32 to the first connecting plate 31, thereby ensuring stable measurement of the measuring steel wire.

[0032] Meanwhile, a limiting block is provided on the first connecting plate 31, which limits the second connecting plate 32.

[0033] The working principle of the coaxial measuring and adjusting device for installing riser clamps in this invention is as follows: Positioning adjustment: After the first angle steel 11 and the second angle steel 12 are positioned, when using them, push the adjustment mechanism 2 to the center line position of the riser clamp so that the upper end of the measuring wire and the upper end of the center line of the riser clamp overlap. Observe the direction of the tilt angle between the measuring wire and the center line of the riser clamp to determine the direction in which the riser clamp needs to be rotated. Interference avoidance: When the riser clamp is in place, if the angle differs significantly from the original position or if the riser clamp needs to pass through the anode position, the measuring wire may interfere with the structure of the guide frame due to the large angle. In this case, the adjustment mechanism 2 can be moved outward to remove the measuring wire from the interference position of the structure, making it easier to observe. Avoidance operation: During the vertical hoisting and positioning of multiple riser clamps, it is necessary to follow the planned transfer route. During the transfer, interference may occur due to the long length of the main track mechanism. At this time, the detachable positioning pin is removed, so that the first angle steel 11 and the second angle steel 12 can be rotated to the inside of the frame through the second connecting plate 32 to ensure safe construction.

[0034] Based on the coaxial measurement and adjustment device for riser clamp installation, this invention achieves precise positioning and flexible adjustment of riser clamp installation through the cooperation of adjustment mechanism 2 and rotation avoidance mechanism 3. It can effectively avoid interference between the measuring steel wire and the structure, significantly improve construction efficiency, reduce costs and ensure operation safety.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
