[0016] In the following, the application will be further described in conjunction with the drawings and the specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0017] As Figures 1-3 ​As shown, the lifting device for hatch cover production comprises a crossbeam 1 and lifting hooks 2, the top of the crossbeam 1 is provided with lifting lugs 11 for connecting a crane, the lifting hooks 2 are arranged below the crossbeam 1 and used for hooking two parts of a hatch cover, the bottom of the crossbeam 1 is provided with a pair of bearing seats 12, a lead screw 3 is arranged between the bearing seats 12, the lead screw 3 is provided with a first sliding block 4 and a second sliding block 5, the first sliding block 4 is located at one end of the lead screw 3, the second sliding block 5 is located at the other end of the lead screw 3, and the bottom of each of the first sliding block 4 and the second sliding block 5 is provided with a lifting hook 2; the thread rotation direction between the lead screw 3 and the first sliding block 4 is opposite to that between the lead screw 3 and the second sliding block 5.

[0018] Two lifting hooks 2 are arranged below the same crossbeam 1, and the two lifting hooks 2 can be used to hook two parts of a hatch cover respectively. Since the first sliding block 4 and the second sliding block 5 are connected with the lead screw 3 through threads, and the thread rotation direction between the first sliding block 4 and the lead screw 3 is opposite to that between the second sliding block 5 and the lead screw 3, when the lead screw 3 is rotated, the first sliding block 4 and the second sliding block 5 will produce displacement in opposite directions on the lead screw 3, that is, the first sliding block 4 and the second sliding block 5 will move closer to each other or move away from each other. When hoisting the two parts of the hatch cover towards the processing position, the distance between the first sliding block 4 and the second sliding block 5 is expanded by rotating the lead screw 3, so that the two parts can be hoisted separately and it is ensured that the two parts will not collide during hoisting. When the two parts are hoisted to the designated position, the lead screw 3 can be rotated in the opposite direction to reduce the distance between the first sliding block 4 and the second sliding block 5, so that the two parts will move closer to each other, facilitating welding and other processing operations on the two parts. After the two parts are processed, the processed hatch cover can be directly hoisted to the storage position without re-hoisting, effectively improving the overall processing efficiency.

[0019] The bottom of the crossbeam 1 is provided with a pair of clamping plates 13, the first sliding block 4 and the second sliding block 5 are clamped between the clamping plates 13, and the first sliding block 4 and the second sliding block 5 can slide between the clamping plates 13. The clamping plates 13 play a clamping role on the first sliding block 4 and the second sliding block 5, ensuring that the first sliding block 4 and the second sliding block 5 connected with the lead screw 3 through threads can translate along the axial direction of the lead screw 3 without rotating, thereby ensuring that the two lifting hooks 2 can move closer to each other or move away from each other stably.

[0020] The end of the crossbeam 1 is provided with a motor 6, the output shaft of the motor 6 is provided with a horizontal bevel gear 60, the end of the lead screw 3 close to the motor 6 is provided with a vertical bevel gear 30, the vertical bevel gear 30 is engaged with the horizontal bevel gear 60, and the motor 6 is used for driving the horizontal bevel gear 60 and the vertical bevel gear 30 to rotate. When the motor 6 is in action, the horizontal bevel gear 60 can be directly driven to rotate, the horizontal bevel gear 60 is engaged with the vertical bevel gear 30, and the vertical bevel gear 30 is sleeved on the lead screw 3. After the horizontal bevel gear 60 rotates, the vertical bevel gear 30 and the lead screw 3 can synchronously rotate, thereby reliably realizing the driving effect on the first sliding block 4 and the second sliding block 5.

[0021] A pair of the clamping plates 13 are located between a pair of the bearing seats 12, the top of the first sliding block 4 and the top of the second sliding block 5 are attached to the bottom of the crossbeam 1, the upper part of the outer wall of the first sliding block 4 and the upper part of the outer wall of the second sliding block 5 are attached to the clamping plate 13, and the lower part of the first sliding block 4 and the lower part of the second sliding block 5 are located below the clamping plate 13. A pair of the clamping plates 13 are perpendicular to the crossbeam 1, so that a cuboid containing space can be formed between a pair of the clamping plates 13 and the crossbeam 1, and the upper part of the first sliding block 4 and the upper part of the second sliding block 5 can be adaptively arranged in the containing space, thereby reliably realizing the limiting effect on the first sliding block 4 and the second sliding block 5.

[0022] The bottom of the first sliding block 4 and the bottom of the second sliding block 5 are both provided with a rotating disc 40, the lifting hook 2 is arranged on the rotating disc 40, and the lifting hook 2 and the rotating disc 40 can rotate around the first sliding block 4 or the second sliding block 5. Under the action of the movable connection of the rotating disc 40, the lifting hook 2 can reliably rotate, so that in the process of hoisting the two components towards the machining position, the two J-shaped lifting hooks 2 can be rotated to opposite directions, thereby maximizing the distance between the two components, and thereby ensuring that the two components will not collide in the hoisting process. When hoisted to the machining position and the two components are machined, the two lifting hooks 2 can be rotated to opposite directions, thereby minimizing the distance between the two components, and facilitating the machining of the two components.

[0023] The above-mentioned embodiments are only the preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application all belong to the scope of protection of the present application.
