DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A fixing tool for a ship shaft comprises a base 1 and a support plate 2. Both sides of the base 1 are upwardly inclined slopes. The support plate 2 is provided with a V-shaped placement groove for placing the ship shaft. A groove 3 adapted to the support plate 2 is provided inside the base 1. A hydraulic cylinder 4 is installed inside the groove 3, and the telescopic end of the hydraulic cylinder 4 is connected to the support plate 2. There are two support plates 2 and two grooves 3, and the two grooves 3 are symmetrical about the center point of the base 1. There are four hydraulic cylinders 4, which are respectively located at the four corners of the support plate 2. When the hydraulic cylinders 4 are started, the hydraulic cylinders 4 can drive the support plate 2 to move up and down. By setting the two sides of the base 1 to upwardly inclined slopes, it is convenient to roll the ship shaft to the top of the base 1 and roll the ship shaft down from the top of the base 1, thereby eliminating the trouble of crane lifting.

[0024] A limit assembly 5 for preliminarily limiting the ship's axis is provided on the support plate 2. The limit assembly 5 includes two shells 502 fixedly connected to the bottom surface of the support plate 2. Threaded rods 503 are rotatably installed inside the two shells 502. A dual-axis motor 501 is installed on the bottom surface of the support plate 2. The two output ends of the dual-axis motor 501 are respectively fixedly connected to one end of the two threaded rods 503 close to each other. The threaded rods 503 located inside the shells 502 are threaded. The threads on the two threaded rods 503 are in opposite directions. When the dual-axis motor 501 is started, the two threaded rods 503 can be driven to rotate in the same direction at the same time.

[0025] The outer surfaces of the two threaded rods 503 are both threadedly connected with the first threaded plates 504. The two first threaded plates 504 are slidably connected to the inside of the two shells 502 respectively. The two threaded rods 503 rotate in the same direction to drive the two first threaded plates 504 to move in opposite directions.

[0026] The upper surfaces of the two first threaded plates 504 are fixedly connected with sliders 505, and the sides of the two sliders 505 away from the two first threaded plates 504 are fixedly connected with trapezoidal clamps 506, the two sliders 505 are slidably connected to the inside of the base 1, and the two trapezoidal clamps 506 are slidably connected to the inside of the V-shaped placement groove. The movement of the two first threaded plates 504 can drive the two sliders 505 and the two trapezoidal clamps 506 to move accordingly. After the ship shaft is placed inside the V-shaped placement groove, the two threaded rods 503 are driven to rotate forward. The forward rotation of the two threaded rods 503 can drive the two first threaded plates 504, the two sliders 505 and the two trapezoidal clamps 506 to move in the direction of the ship shaft, thereby clamping and limiting the ship shaft.

[0027] A clamping assembly 6 for further limiting the ship's shaft is provided above the base 1. The clamping assembly 6 includes a U-shaped plate 601 fixedly connected to the upper surface of the base 1. A bidirectional screw rod 602 is rotatably installed inside the U-shaped plate 601. A servo motor 603 is installed on the back of the U-shaped plate 601. The output end of the servo motor 603 is fixedly connected to one end of the bidirectional screw rod 602. The outer surface of the bidirectional screw rod 602 is threadedly connected to two symmetrical second threaded plates 604. The two second threaded plates 604 are both slidably connected to the U-shaped plate 601. The servo motor 603 is started. When the servo motor 603 drives the bidirectional screw rod 602 to rotate forward, the two second threaded plates 604 can be driven to move in a direction close to each other. When the servo motor 603 drives the bidirectional screw rod 602 to rotate reversely, the two second threaded plates 604 can be driven to move in a direction away from each other.

[0028] The outer surfaces of the two second threaded plates 604 are fixedly connected to two right-angle plates 605, and the four right-angle plates 605 are fixedly connected to upper clamping blocks 606. The four upper clamping blocks 606 are provided with V-shaped pressing grooves. The movement of the second threaded plates 604 can drive the right-angle plates 605 and the upper clamping blocks 606 to move accordingly. While lifting and raising the ship's shaft, the upper clamping blocks 606 can be driven to move to just above the ship's shaft, so that after the ship's shaft is moved to a specified height, the upper clamping blocks 606 can further squeeze and limit the ship's shaft.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
