Description

Technical Field

[0001] This utility model relates to the technical field of jacket foundation drainage devices, and in particular to a jacket foundation drainage device. Background Technology

[0002] The launching of jackets is a crucial step in the field of shipbuilding engineering and offshore oil and gas development facilities and equipment. It refers to the process of unloading a jacket from a barge into the sea. Jackets are an essential component of offshore oil and gas extraction facilities, acting like a foundation to support the entire offshore platform and ensure its stability and safety.

[0003] The existing Chinese utility model patent with application number CN202120249706.7 relates to a low-cost jacket launching device, which includes a hull, winch, anchor system, ramp, traction cable, guide device, positioning device, launching roller conveyor and horizontal roller conveyor, etc., which can shorten the construction period and improve efficiency.

[0004] However, the aforementioned device does not have the ability to limit the position of the jacket in actual use. Since the hull is always in the sea, when the jacket is placed on the hull, it will be displaced with the swaying of the hull, which will affect the normal use of cables, wire ropes, etc. to fix the jacket. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a jacket launching device that uses a traction device to provide tension to the side of the jacket away from the ship's side, a limiting device to limit the side of the jacket as it is introduced into the ship's hull, thereby reducing the swaying amplitude of the jacket during the fixing process, and a supporting device to provide auxiliary support for the jacket during the launching process, thus improving the practicality of the device.

[0006] This utility model discloses a jacket launching device, comprising a traction device, a limiting device, and a supporting device. The limiting device is installed on the traction device, and the supporting device is installed on the traction device. The traction device provides tension to the side of the jacket away from the ship's side, the limiting device limits the side of the jacket as it is introduced into the ship's hull, reducing the swaying amplitude of the jacket during the fixing process, and the supporting device provides auxiliary support for the jacket launching process, thereby improving the practicality of the device.

[0007] Preferably, the traction device includes a hull, a support frame, a wire rope roller, a reducer, and a motor. The wire rope roller is mounted on the rear of the upper end of the hull via the support frame. The reducer is mounted on the left side of the support frame, and the motor is mounted on the reducer. The output end of the reducer is connected to the wire rope roller. The wire rope on the wire rope roller is used to pull and fix one end of the guide frame, which facilitates the loading and launching of the guide frame and prevents the guide frame from slipping too quickly during the launching process. The motor is turned on to drive the wire rope roller to rotate through the reducer, thereby assisting in the traction of the guide frame for launching and loading, and improving the practicality of the device.

[0008] Preferably, it also includes support rails and arc-shaped grooves. A set of support rails is provided on the left and right sides of the upper end face of the hull, and an arc-shaped groove is provided on the upper end face of the support rails. The support rails and arc-shaped grooves provide support for the jacket, and the arc-shaped grooves limit the sliding path of the jacket during the launching process, preventing the jacket from shifting laterally on the hull due to the swaying of the hull caused by the waves during the launching process, thus improving the practicality of the device.

[0009] Preferably, the limiting device includes a transverse trolley, limiting sliders, electric cylinders, positioning connecting blocks, limiting grooves, and positioning holes. A set of limiting sliders is provided on the left and right sides of the lower inner side of the transverse trolley. Two sets of electric cylinders are installed on the left and right sides of the transverse trolley, respectively. The limiting sliders have two sets of grooves on their inner sides corresponding to the positions of the two sets of electric cylinders. The moving end of the electric cylinder extends through the transverse trolley into the corresponding groove on the limiting slider and connects with a set of positioning connecting blocks. A set of limiting grooves is provided on the left and right sides of the supporting track. The lower part of the trolley is mounted on the support rail, and the limiting slider is located inside the limiting groove. Multiple sets of positioning holes are provided on the inner surface of the limiting groove, and the multiple sets of positioning holes are evenly distributed in pairs. According to the size of the guide frame, the position of the trolley on the support rail is adjusted, and then the electric cylinder is controlled to extend so that the positioning connecting block is inserted into the corresponding positioning hole in the limiting groove, thereby fixing the position of the trolley on the support rail. The cooperation between the limiting slider and the limiting groove makes it easy for the operator to adjust the position of the trolley, improving the practicality of the device.

[0010] Preferably, it also includes support wheels, connecting sockets, and limit blocks. The support wheels are located in the middle of the transverse trolley, and the lower part of the support wheels can be pressed into the arc-shaped groove. The connecting socket is installed on the upper part of the transverse trolley, and the limit blocks are connected to the connecting sockets. The support wheels facilitate the movement of the shaft by the operator, reducing the labor intensity of the operator in adjusting the position of the shaft. The limit blocks intercept and limit the rear of the guide frame, and together with the pulling force of the traction device, fix the rear position of the guide frame during the loading process, making it easier for the operator to fix the entire guide frame, thus improving the practicality and stability of the device.

[0011] Preferably, the support device includes a mounting groove, a rotating shaft, an adjusting arm, a hydraulic cylinder, and a rotating shaft seat. A set of mounting grooves is provided on the left and right sides of the front end face of the hull. The front part of the mounting groove is connected to the adjusting arm via a rotating shaft. The fixed end of the rotating shaft seat is connected to the front of the lower end face of the mounting groove via a hydraulic cylinder. The moving end of the rotating shaft seat is connected to the rear of the lower end face of the adjusting arm via another set of hydraulic cylinders. During the launching process of the guide frame, after the front part of the guide frame enters the water, the rotating shaft seat is extended to lift the rear part of the adjusting arm. The rear part of the adjusting arm lifts the rear part of the guide frame, thereby adjusting the water entry angle of the tail of the guide frame. This facilitates the subsequent direct adjustment of the guide frame to a vertical state in the water, improving the practicality of the device.

[0012] Preferably, the device also includes fixing blocks and wire rope fixing rods. Multiple sets of fixing blocks are respectively provided on the left and right sides of the upper end face of the hull, and wire rope fixing rods are installed inside the fixing blocks. The multiple sets of fixing blocks and wire rope fixing rods on the hull make it easy for operators to pull and fix the main body of the guide frame with wire ropes or cables, which improves the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the traction device provides tension to the side of the guide frame away from the ship's side, the limiting device limits the side of the guide frame that is introduced into the ship's hull, reducing the swaying amplitude of the guide frame during the fixing process, and the supporting device provides auxiliary support for the guide frame during the launching process, thus improving the practicality of the device.
