Description

Technical Field

[0001] This utility model relates to the field of ship repair technology, specifically to an automatic fixing device for ship repair. Background Technology

[0002] Ship fixing devices are needed during the repair process.

[0003] Utility model patent CN217320699U discloses an automatic fixing device for ship repair. This device solves the problems of existing ship fixing devices, which are inconvenient for transporting the device itself to the ship, causing significant inconvenience during repairs and severely impacting the difficulty of repair work. Furthermore, existing ship fixing devices are not convenient for supporting the ship during repairs, significantly affecting the efficiency and increasing the cost of repair work. The new device involves the user fixing the bottom of a movable base to the ground, then attaching one end of a steel cable to the ship. When a motor drives a take-up roller to retract the steel cable, the cable pulls the ship onto the first and second support platforms on the movable base. At this point, the first and second support platforms can support the ship. When the user moves the mobile seat, it can detach the ship from the ship via the first and second support platforms. This allows the mobile seat to detach the ship to the verified maintenance location via the first and second support platforms. This method has a simple structure, but in actual use, the distance between the front and rear rotating plates is fixed. When positioning ships of different widths, the rotating plates cannot guarantee that the plane of the rotating plate is always in contact with the side of the ship. It is easy for the edge of the rotating plate to be in contact with the ship, resulting in a small contact area between the rotating plate and the ship. On the one hand, this makes the stability of the rotating plate in fixing the ship poor, and on the other hand, it makes the pressure on the contact surface between the rotating plate and the ship high, which can easily damage the ship.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, an automatic fixing device for ship repair includes a movable base 1, a traction mechanism 2 on the top of the movable base 1, a first electric cylinder 3 fixedly connected to the front and rear sides of the right side of the movable base 1, a front seat 4 fixedly connected to the output end of the first electric cylinder 3, a first support platform 5 fixedly connected to the bottom of the inner wall of the movable base 1, a second support platform 6 fixedly connected to the top of the front seat 4, a ramp 7 fixedly connected to the right side of the second support platform 6, the ramp 7 being fixedly connected to the front seat 4, a drive box 8 fixedly connected to the top of the front seat 4, a threaded rod with positive and negative threads rotatably connected inside the drive box 8, and sliders 10 slidably connected to the front and rear sides of the drive box 8, the sliders 10 being threadedly connected to the threaded rod with positive and negative threads. The front of the drive box 8... A first motor 9 is fixedly connected, and the output end of the first motor 9 is fixedly connected to a threaded rod. Telescopic limit rods 11 are fixedly connected to all four sides of the top of the slider 10. A movable plate 13 is fixedly connected to the top of the telescopic limit rods 11. A second electric cylinder 12 is fixedly connected to the top of the slider 10. The output end of the second electric cylinder 12 is fixedly connected to the movable plate 13. A clamping plate 15 is provided above the movable plate 13. Fixing blocks 16 are fixedly connected to both sides of the surface of the clamping plate 15. A hinge block 17 is hinged inside the fixing block 16. Torsion springs 18 are fixedly connected to both sides of the hinge block 17. The end of the torsion spring 18 away from the hinge block 17 is fixedly connected to the fixing block 16. An installation mechanism 14 is provided on the top of the movable plate 13.

[0022] refer to Figure 1 The traction mechanism 2 includes a winding box 19 fixedly connected to the surface of the movable seat 1. A winding roller is rotatably connected inside the winding box 19. A second motor 20 is fixedly connected to the front of the winding box 19. The output end of the second motor 20 is fixedly connected to the winding roller. A steel wire rope 21 is wound on the surface of the winding roller.

[0023] As a technical optimization of this utility model, by setting up the traction mechanism 2, the operator ties the end of the wire rope 21 away from the winding roller to the end of the ship. The second motor 20 rotates to drive the winding roller to rotate, thereby pulling the ship to the left, so that the ship moves to the top of the first support platform 5 and the second support platform 6.

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5The mounting mechanism 14 includes a slide rail 22 fixedly connected to the top of the movable plate 13. A first T-shaped slider 23 is slidably connected inside the slide rail 22. The first T-shaped slider 23 has slots on both sides of its top. A bolt 24 is threaded inside the slide rail 22 and is inserted into the slot. A second T-shaped slider 25 is fixedly connected to the surface of the hinge block 17. A groove is provided on the right side of the movable plate 13, and the second T-shaped slider 25 is slidably connected to the groove.

[0025] As a technical optimization of this utility model, by setting the installation mechanism 14, when the operator installs the hinge block 17, the first T-shaped slider 23 slides into the interior of the slide rail 22. Then the operator tightens the bolt 24 so that the bolt 24 is inserted into the slot, thereby positioning the first T-shaped slider 23 and preventing the first T-shaped slider 23 from separating from the slide rail 22. During the process of the first T-shaped slider 23 sliding into the slide rail 22, it is necessary to ensure that the second T-shaped slider 25 is aligned with the slide groove so that the second T-shaped slider 25 slides into the slide groove. Through the setting of the slide groove and the second T-shaped slider 25, the hinge block 17 can be auxiliary supported and positioned.

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 Elastic bands 27 are fixedly connected to both sides of the top and bottom of the hinge block 17, and the end of the elastic band 27 away from the hinge block 17 is fixedly connected to the clamping plate 15.

[0027] As a technical optimization of this utility model, the elastic band 27 can be used to apply elastic force to the clamping plate 15, so that the clamping plate 15 can automatically reset when it is not subjected to external force.

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The clamping plate 15 is internally connected to a rotatable roller 26, and there are several rollers 26.

[0029] As a technical optimization of this utility model, the setting of roller 26 can reduce the friction between the clamping plate 15 and the ship, so that when the clamping plate 15 positions the ship in the forward and backward direction, it will not affect the ship's left and right movement too much. The surface of roller 26 is covered with a rubber sleeve, which can protect the ship.

[0030] refer to Figure 1 The tops of the first support platform 5 and the second support platform 6 are both fixedly connected with rubber sheets 28, and the inside of the ramp 7 is rotatably connected with rollers 29.

[0031] As a technical optimization of this utility model, the rubber sheet 28 can drag the bottom of the ship, which can prevent the bottom of the ship from being suspended in the air. The roller 29 can reduce the friction between the ship and the ramp 7, thereby making it easier for the ship to enter the top of the first support platform 5 and the second support platform 6 along the ramp 7.

[0032] The working principle and usage process of this utility model are as follows: When the ship is towed to the top of the first support platform 5 and the second support platform 6 by the traction mechanism 2, the operator can adjust the extension or retraction of the second electric cylinder 12 according to the size of the ship, thereby driving the movable plate 13, the mounting mechanism 14, the hinge block 17, the fixing block 16 and the clamping plate 15 to move up or down. Then the operator starts the first motor 9 to rotate and drive the positive and negative threaded rod to rotate, thereby driving the sliders 10 on the front and rear sides to move closer to each other, thereby driving the second electric cylinder 12, the movable plate 13, the mounting mechanism 14, the hinge block 17, the fixing block 16 and the clamping plate 15 on the front and rear sides to move closer to each other until the clamping plate 15 is in contact with the surface of the ship. The clamping plate 15 is hinged to the hinge block 17 through the fixing block 16, so that the clamping plate 15 can tilt, thereby increasing the contact area between the clamping plate 15 and the ship, thereby improving the stability of the ship fixation. With the setting of the torsion spring 18 and the elastic band 27, when the operator adjusts the clamping plate 15 away from the ship, the clamping plate 15 can automatically return to its original position.

[0033] The aforementioned traction mechanism 2 is similar in principle to the traction mechanism mentioned in the utility model patent "An Automatic Fixing Device for Ship Repair" (publication number: CN217320699U), and achieves the same effect. Therefore, this application will not elaborate further.
