Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary positioning devices for anchor chain manufacturing, and particularly to an anchor chain production positioning device. Background Art

[0002] Anchor chains and mooring chains are important components for positioning offshore floating bodies. They are usually produced by a four-station rotating unit. The four stations respectively correspond to link forming, flash welding, deburring, and swaging (shaping). In the middle of the unit is a rotating device that controls four short chains respectively. The four short chains are controlled by a positioning device installed on the top of the rotating machine. During the production process of the anchor chain, the vertically suspended anchor chain needs to be adjusted horizontally and in height according to different stations. The traditional positioning device uses mechanical control, with poor positioning accuracy, difficult adjustment, high labor intensity for workers, and affects production efficiency and product quality.

A horizontal adjustment hydraulic motor is arranged on the gear-rack mechanism. The anchor chain is positioned and adjusted horizontally through the linear guide rail and the gear-rack mechanism. The linear guide rail includes a guide rail body and a slider. An installation seat is arranged on the slider. A bearing seat is arranged in the middle of the installation seat. A sprocket is connected to the bearing seat through a shaft. A transmission gear is arranged on the shaft on one side of the sprocket. One end of the installation seat is connected through a bracket to a height adjustment hydraulic motor. A small gear is arranged on the output shaft of the height adjustment hydraulic motor. The small gear meshes with the transmission gear. The vertically suspended anchor chain is positioned and adjusted in height through the rotation of the sprocket.

[0005] Preferably: The gear-rack mechanism includes a gear and a rack. The gear is connected to the output shaft of the horizontal adjustment hydraulic motor, and the gear meshes with the rack.

[0006] Preferably: The output shaft of the height adjustment hydraulic motor is perpendicular to the output shaft of the horizontal adjustment hydraulic motor.

[0014] The present invention will be further described below.

[0015] Referring to the attached drawings, an anchor chain production positioning device is characterized in that: it includes a U-shaped frame symmetrically arranged front and back. A linear guide rail 1 is arranged inside the U-shaped frame, and a gear rack mechanism 2 is arranged outside the U-shaped frame. A horizontal adjustment hydraulic motor 4 is arranged on the gear rack mechanism 2 to perform horizontal positioning adjustment on the anchor chain through the linear guide rail 1 and the gear rack mechanism 2; the linear guide rail 1 includes a guide rail body and a slider. A mounting seat 3 is arranged on the slider. A bearing seat is arranged in the middle of the mounting seat 3. A sprocket 5 is connected to the bearing seat through a shaft. A transmission gear 6 is arranged on the shaft on one side of the sprocket 5. One end of the mounting seat 3 is connected through a bracket 9 to a height adjustment hydraulic motor 8. A pinion 7 is arranged on the output shaft of the height adjustment hydraulic motor 8, and the pinion 7 meshes with the transmission gear 6 to perform height-direction positioning adjustment on the vertically suspended anchor chain through the rotation of the sprocket 5.

[0016] In this preferred embodiment, the gear rack mechanism 2 includes a gear and a rack. The gear is connected to the output shaft of the horizontal adjustment hydraulic motor 4, and the gear meshes with the rack.

[0017] In this preferred embodiment, the output shaft of the height adjustment hydraulic motor 8 is perpendicular to the output shaft of the horizontal adjustment hydraulic motor 4.

[0018] In this preferred embodiment, the horizontal adjustment hydraulic motor 4 is arranged on the mounting seat 3.

[0019] During specific implementation, the present invention is located at one end of the four-station rotating unit close to the chain-making unit. The anchor chain is vertically suspended through the sprockets at each station. When position adjustment is required, the horizontal adjustment hydraulic motor 4 drives the gear-rack mechanism 2 to drive. The mounting seat 3, together with the sprocket 5, the transmission gear 6, and the height adjustment hydraulic motor 8, makes a horizontal movement on the linear guide rail 2 to precisely adjust the horizontal position of the vertically suspended anchor chain for different stations; the height adjustment hydraulic motor 8 drives the transmission gear 6 and the sprocket 5 to rotate through the pinion 7 to adjust the height dimension of the anchor chain on the side of the chain-making unit. The present invention adopts a hydraulic motor gear drive structure, which can achieve high-torque precise positioning. With the horizontal adjustment positioning of the linear guide rail, the repeated positioning accuracy of the anchor chain can be guaranteed, and the precise positioning dimensions required during the production of different specifications of anchor chains can be satisfied.
