Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for ship repair, and in particular, it is a deformation-resistant tooling for repairing dynamically adjustable hatch covers. Background Technology

[0002] Repairing bulk carrier hatch covers is a common task, primarily involving the replacement and repair of hatch cover rubber strips, top plates, side plates, and internal structures. Welding is frequently involved. Due to heat, the hatch covers undergo transverse and longitudinal deformation, causing them to lose their airtightness. Current industry practices for preventing deformation primarily involve rigidly connecting structural steel sections before cutting, forming a single unit that compensates for stress caused by heat and cooling. Existing anti-deformation tooling for hatch covers uses integrally formed angle steel, T-shaped steel, or round pipes, which are heavy, labor-intensive, and cannot effectively adjust deformed hatch covers, nor can they be reused multiple times. This approach suffers from drawbacks such as high cost, low efficiency, and heavy weight. Summary of the Invention

[0003] This invention provides a dynamically adjustable hatch cover repair anti-deformation tooling, which can effectively reduce hatch cover deformation caused by heat treatment.

[0004] This utility model solves the above-mentioned technical problems through the following technical solutions.

[0005] A dynamically adjustable hatch repair anti-deformation tooling includes an upper connecting end, a lower connecting end, an adjustment mechanism, and a measuring mechanism. The adjustment mechanism includes a positioning pin, an upper sliding cylinder, and a lower sliding cylinder. The upper sliding cylinder is inserted into the lower sliding cylinder. Both the upper and lower sliding cylinders are provided with positioning holes. The positioning holes of the upper sliding cylinder and the lower sliding cylinder are spaced the same and matched. The total height of the upper and lower sliding cylinders can be adjusted by inserting the positioning pin into the positioning holes on the upper and lower sliding cylinders. The top of the upper sliding cylinder and the bottom of the lower sliding cylinder are fixedly connected to the upper connecting end and the lower connecting end, respectively. The side wall of the lower sliding cylinder is provided with a mounting plate, on which the measuring mechanism is mounted.

[0006] The aforementioned dynamically adjustable hatch repair anti-deformation tooling also includes a fine-tuning mechanism between the upper sliding cylinder and the upper connecting end.

[0007] The aforementioned dynamic adjustable hatch repair anti-deformation tooling includes a fine-tuning mechanism comprising a fine-tuning screw, an upper fine-tuning sleeve, a lower fine-tuning sleeve, and an adjusting handle. Both the upper and lower fine-tuning sleeves have internal threads. The upper and lower ends of the fine-tuning screw are screwed to the upper and lower fine-tuning sleeves, respectively. The adjusting handle is fixed to the side wall of the fine-tuning screw. The bottom of the upper connecting end is connected to the top of the upper fine-tuning sleeve, and the top of the upper sliding cylinder is connected to the bottom of the lower fine-tuning sleeve.

[0008] The aforementioned dynamically adjustable hatch repair anti-deformation tooling uses an infrared rangefinder with a display screen as its measuring mechanism.

[0009] The aforementioned dynamic adjustable hatch cover repair anti-deformation tooling uses T-shaped steel for both the upper and lower connecting ends.

[0010] Compared with existing technologies, this utility model uses a two-stage adjustment method—an adjustment mechanism and a fine-tuning structure—to accommodate installations at different hatch cover heights and match varying hatch cover-to-deck distances. The upper and lower connecting ends are partially consumed to cover the daily wear and tear associated with on-site welding on ships, avoiding the waste caused by integrally formed steel and reducing overall consumption. The measuring mechanism displays the distance between the deck and hatch cover in real time during installation. Adjustments can be made based on the actual distance, improving the ease of adjustment. Attached Figure Description

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model.

[0015] like Figures 1 to 2As shown, this utility model includes an upper connecting end 1, a lower connecting end 2, an adjustment mechanism, and a measuring mechanism 3. The adjustment mechanism includes a positioning pin 4, an upper sliding cylinder 5, and a lower sliding cylinder 6. The upper sliding cylinder 5 is inserted into the lower sliding cylinder 6. Both the upper sliding cylinder 5 and the lower sliding cylinder 6 are provided with positioning holes 7. The positioning holes 7 of the upper sliding cylinder 5 and the lower sliding cylinder 6 are spaced the same and matched. The total height of the upper sliding cylinder 5 and the lower sliding cylinder 6 can be adjusted by inserting the positioning pin 4 into the positioning holes 7 on the upper sliding cylinder 5 and the lower sliding cylinder 6. The top of the upper sliding cylinder 5 and the bottom of the lower sliding cylinder 6 are fixedly connected to the upper connecting end 1 and the lower connecting end 2, respectively. The side wall of the lower sliding cylinder is provided with a mounting plate 8, and the measuring mechanism 3 is mounted on the mounting plate 8. Before welding or performing other heat treatment repairs on the hatch cover, first weld the lower connecting end 2 to the deck. Then adjust the length of the upper sliding cylinder 5 inserted into the lower sliding cylinder 6 so that the upper connecting end 1 is against the bottom surface of the hatch cover. Next, insert the positioning pin 4 into the positioning hole 7 on the upper sliding cylinder 5 and the lower sliding cylinder 6, and then weld the upper connecting end 1 to the bottom surface of the hatch cover securely. Preferably, both the upper connecting end 1 and the lower connecting end 2 are made of T-shaped steel. The T-shaped steel allows the connecting end to connect to the bottom of the hatch cover in both the transverse and longitudinal directions.

[0016] To further precisely adjust the distance between the upper connecting end 1 and the lower connecting end 2 to accurately match the distance between the hatch cover and the deck, a fine-tuning mechanism is provided between the upper sliding cylinder 5 and the upper connecting end 1. The fine-tuning mechanism includes a fine-tuning screw 9, an upper fine-tuning sleeve 10, a lower fine-tuning sleeve 11, and an adjusting handle 12. Both the upper and lower fine-tuning sleeves 10 and 11 have internal threads. The upper and lower ends of the fine-tuning screw 9 are screwed to the upper and lower fine-tuning sleeves 10 and 11, respectively. The adjusting handle 12 is fixed to the side wall of the fine-tuning screw 9. The bottom of the upper connecting end 1 is connected to the top of the upper fine-tuning sleeve 10, and the top of the upper sliding cylinder 5 is connected to the bottom of the lower fine-tuning sleeve 11. By rotating the adjusting handle 12, the fine-tuning screw 9 can be rotated, thereby adjusting the distance between the upper and lower fine-tuning sleeves 10 and 11.

[0017] The measuring mechanism 3 is an infrared rangefinder with a display screen. During the heat treatment process, deformation will occur at the connection point between the upper connecting end 1 and the hatch cover. The display screen of the measuring mechanism can show the distance between the deck and the hatch cover in real time, and the adjusting handle 12 can be adjusted to cope with the deformation after cooling. This ultimately maintains the distance between the hatch cover and the deck, thereby preventing deformation of the hatch cover due to heat treatment.

[0018] The working process is as follows: Before welding or performing other heat treatment repairs on the hatch cover, the lower connecting end 2 is first welded to the deck. Then, the length of the upper sliding cylinder 5 inserted into the lower sliding cylinder 6 is adjusted so that the upper connecting end 1 is against the bottom surface of the hatch cover. Next, the positioning pin 4 is inserted into the positioning holes 7 on the upper sliding cylinder 5 and the lower sliding cylinder 6. Then, the upper connecting end is pressed against the bottom surface of the hatch cover using a fine-tuning mechanism. Finally, the upper connecting end 1 and the bottom surface of the hatch cover are welded securely. This maintains the distance between the hatch cover and the deck. During heat treatment, the hatch cover may bulge or dent. Workers can read real-time data through the display screen of the measuring mechanism and then adjust the total height of the fine-tuning structure by rotating the handle to lift or lower the hatch cover. Ultimately, after cooling, the hatch cover position is maintained within the normal range.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
