[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 external ship repair scaffold includes two telescopic ladders 1. Each telescopic ladder 1 has a buckle 2 fixedly connected to its front and rear sides. The buckle 2 has an arc-shaped groove 3 inside, and an arc-shaped frame 4 is slidably connected inside the arc-shaped groove 3. The surface of the arc-shaped frame 4 has several first openings 5. A first bolt 6 is threaded into the buckle 2 and inserted into the first opening 5. A workbench 7 is provided on the surface of the telescopic ladder 1.

[0022] refer to Figures 1 to 5The telescopic ladder 1 includes a main ladder 8, the top of which is fixedly connected to the inverted buckle 2. The front and rear sides of the left side of the main ladder 8 are fixedly connected to slide rails 9. The slide rails 9 are slidably connected to the inner side of the slide rails 9. One of the slide rails 9 has a second opening 11 on its surface. There are several second openings 11. The top of the side of the slide ladder 10 near the workbench 7 is provided with a slot. The inner side of the second opening 11 is threaded with a second bolt 12. The second bolt 12 is inserted into the slot. There are several second bolts 12.

[0023] As a technical optimization of this utility model, by setting up the telescopic ladder 1, the operator can adjust the relative movement between the main ladder 8 and the secondary ladder 10, thereby adjusting the overall height of the telescopic ladder 1. The operator can loosen the second bolt 12 and then adjust the secondary ladder 10 to slide within the slide rail 9. When the secondary ladder 10 slides to the appropriate position, the operator tightens the second bolt 12 so that the second bolt 12 is inserted into the slot, thereby locking the position of the secondary ladder 10 and locking the overall height of the telescopic ladder 1.

[0024] refer to Figures 1 to 3 The surface of the main ladder 8 is provided with a slide groove 13, and the first slider 14 and the second slider 15 are slidably connected inside the slide groove 13. The top of the first slider 14 is hinged to the bottom of the workbench 7, and the top of the second slider 15 is hinged to a movable column 16. The front and rear sides of the bottom of the workbench 7 are both hinged to sleeves 17, which are slidably connected to the movable column 16. The surface of the movable column 16 is provided with a third through-hole 18, and there are several third through-holes 18. The third through-holes 18 are evenly distributed on the surface of the movable column 16. The inside of the sleeve 17 is threaded with a third bolt 19, which is inserted into the third through-hole 18.

[0025] As a technical optimization of this utility model, by setting up the slide groove 13, the first slider 14, the second slider 15, the movable column 16, the third port 18, the third bolt 19 and the sleeve 17, when the tilt angle of the telescopic ladder 1 changes, in order to ensure that the worktable 7 is always in a horizontal state, the angle of the worktable 7 needs to be adjusted. At this time, the operator can move the sleeve 17 up and down. The movable column 16 is slidably connected to the sleeve 17. When the sleeve 17 moves up and down, it will drive the worktable 7 to rotate around the hinge part between the first slider 14 and the worktable 7, thereby adjusting the angle of the worktable 7. When the worktable 7 is in a horizontal state, the operator tightens the third bolt 19 so that the third bolt 19 is inserted into the third port 18, thereby locking the angle of the worktable 7.

[0026] refer to Figure 1 and Figure 5 The surface of the ladder 10 is hinged with a support frame 22, and the bottom of the support frame 22 is provided with anti-slip texture, and the number of anti-slip textures is several.

[0027] As a technical optimization of this utility model, by setting the support frame 22, the friction between the bottom of the large ladder 10 and the ground can be increased, thereby avoiding the phenomenon of slippage at the bottom of the large ladder 10 and improving the stability of the device.

[0028] refer to Figure 1 and Figure 2 The front and back sides of the inner wall of the workbench 7 are provided with sliding grooves, and the extension table 23 is slidably connected inside the sliding grooves.

[0029] As a technical optimization of this utility model, by setting up the sliding groove and the extension platform 23, the operator can pull the extension platform 23 to the left as needed, so that the operator can stand inside the extension platform 23, which facilitates the maintenance of the ship and improves the practicality of the device.

[0030] refer to Figure 1 , Figure 3 and Figure 4 The surface of the main ladder 8 is provided with a fourth opening 20, and there are several fourth openings 20. The first slider 14 and the second slider 15 are both provided with a slot on the side near the worktable 7. The fourth opening 20 is internally threaded with a fourth bolt 21, and the fourth bolt 21 is inserted into the slot.

[0031] As a technical optimization of this utility model, by setting the fourth port 20, the fourth bolt 21 and the slot, the operator can tighten the fourth bolt 21 so that the fourth bolt 21 is inserted into the fourth port 20, thereby locking the position of the first slider 14 and the second slider 15. Similarly, the operator can disassemble and assemble the fourth bolt 21 and adjust the position of the first slider 14 and the second slider 15, thereby adjusting the height of the worktable 7, which makes it easier for the operator to adjust the position of the worktable 7 as needed, thereby improving the practicality of this device.

[0032] The working principle and usage process of this utility model are as follows: In use, the operator first adjusts the position of the ramp 10 as needed, and then adjusts the overall height of the device. Then, the operator places the bottom of the ramp 10 in contact with the ground and hangs the inverted buckle 2 on the surface of the ship's railing. Then, the operator slides the arc frame 4 in the arc groove 3 to lock the inverted buckle 2, preventing it from separating from the ship's railing. Then, the operator tightens the first bolt 6 so that it engages with the first through-hole 5, thereby locking the position of the arc frame 4 and preventing the inverted buckle 2 from separating from the ship's railing. Then, the operator adjusts the position and tilt angle of the worktable 7 as needed. Finally, the operator stands in the worktable 7 to repair the surface of the ship.
