After the ship blocks are constructed, they are then erected together. With the active promotion of the modern shipbuilding mode, the block assembly shipbuilding method has been mastered by more and more shipyards; the block assembly shipbuilding method is inseparable from hull blocks, and hull blocks have become the basic units of ship assembly. The erection of hull blocks is an important work content in the overall assembly process of the ship's hull. When erecting hull blocks, specific support devices are mostly used for assistance.

DETAILED DESCRIPTION OF THE INVENTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides the following technical solutions:

[0026] Embodiment 1: The existing hydraulic support for hull block erection cannot move automatically on a large channel steel track and cannot perform automatic positioning. To solve this technical problem, the following technical content is disclosed in this embodiment:

[0027] A hydraulic support for hull block erection with a positioning function, comprising a housing 1, a roller assembly 2, a first transmission mechanism 4, and a second transmission mechanism 5. A plurality of roller assemblies 2 are rotatably connected inside the housing 1. A second sensor 12 is fixedly installed on the inner wall of the housing 1. An electromagnetic slide rail 6 is installed at the top end outside the housing 1. A first sensor 11 is installed inside the electromagnetic slide rail 6. A strengthening assembly 7 and a hydraulic cylinder 8 are installed at the top end of the electromagnetic slide rail 6. The hydraulic cylinder 8 is located inside the strengthening assembly 7. A tray 9 is fixedly installed at the top end of the hydraulic cylinder 8. Infrared sensors 10 are fixedly installed at equal angles inside the top end of the tray 9. The first transmission mechanism 4 and the second transmission mechanism 5 are respectively arranged at the front and rear ends outside the housing 1. The outside of the first transmission mechanism 4 is connected to a motor 3;

[0028] As Figures 1-3 and Figure 5As shown in the figure, the first transmission mechanism 4 includes a first gear 401 and a second gear 402. The second transmission mechanism 5 includes a first conveyor pulley 501, a second transmission pulley 502, and a conveyor belt 503. Start the motor 3 fixedly installed at the front end outside the housing 1 through a plate member. The output end of the motor 3 is fixedly connected to the first gear 401. The motor 3 drives the first gear 401 to rotate. The first gear 401 and the second gear 402 are meshed and connected. The first gear 401 drives the second gear 402 to rotate. The second gear 402 is fixedly connected to the front side of the leftmost connecting shaft 202. The second gear 402 drives the leftmost connecting shaft 202 to rotate. The first conveyor pulley 501 and the second transmission pulley 502 are respectively fixedly installed at the rear sides of the leftmost and rightmost connecting shafts 202. The leftmost connecting shaft 202 drives the first conveyor pulley 501 to rotate. Both the first conveyor pulley 501 and the second transmission pulley 502 are arranged inside the conveyor belt 503. Through the transmission of the conveyor belt 503, the first conveyor pulley 501 drives the second transmission pulley 502 to rotate, so that the second transmission pulley 502 drives the rightmost connecting shaft 202 to rotate. The roller body 201 is fixedly installed outside the connecting shaft 202. The connecting shaft 202 drives the roller body 201 to rotate. The roller body 201 contacts the large channel steel track, so that the roller body 201 drives the entire device to move on the large channel steel track. When stopping for positioning, just stop the motor 3 directly. The above-mentioned roller body 201 and the connecting shaft 202 are both roller assemblies 2. The function of the first transmission mechanism 4 is to make the running speeds of all the roller bodies 201 inside the housing 1 the same, so that the device moves more smoothly;

[0029] Embodiment 2: The existing hydraulic support for hull block erection cannot automatically move the electromagnetic slider 602 and cannot automatically position. Therefore, in this embodiment, through the following technical solutions, as Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, the electromagnetic slide rail 6 includes an electromagnetic track 601, an electromagnetic slider 602, and an electromagnetic sensor 603. The electromagnetic slider 602 is slidably connected to the top of the electromagnetic track 601. The electromagnetic slider 602 is made of a magnetic material. The electromagnetic sensors 603 are respectively fixedly installed at the left and right ends inside the electromagnetic track 601. Turn on the electromagnetic sensors 603, and the magnetic field generated by them guides the movement of the electromagnetic slider 602. Turn off the electromagnetic sensors 603 to make the electromagnetic slider 602 stop moving, so as to lock it;

[0030] Embodiment 3: The existing hydraulic support for hull block erection cannot make the hull and the tray 9 accurately aligned and cannot connect the hull and the tray 9 more firmly. Therefore, in this embodiment, through the following technical solutions, as Figure 1 、 Figure 2 and Figure 3As shown, mounting grooves are provided at equal angles on the top of the tray 9, and infrared sensors 10 are fixedly installed in the mounting grooves. When all the infrared sensors 10 are blocked by the hull, it indicates that the hull and the tray 9 are precisely aligned. When any infrared sensor 10 is not blocked by the hull, the infrared sensor 10 blocked by the hull will sound an alarm or flash to remind the staff to make adjustments until the infrared sensors 10 are completely blocked by the hull.

[0031] Embodiment 4: The existing hull segment closing hydraulic support is poor in stability, and the supporting force of the tray 9 is small, making it easy to tilt, thereby causing the hull to fall off. Therefore, this embodiment adopts the following technical solutions, such as Figures 1-5 As shown, the reinforcing assembly 7 includes a manual telescopic rod 701 and a reinforcing rib 702. The manual telescopic rod 701 and the reinforcing rib 702 are both fixedly mounted on the top of the electromagnetic slider 602. The output end of the manual telescopic rod 701 is fixedly mounted with a tray 9. When the tray 9 is lifted and lowered by the hydraulic cylinder 8, the output end of the manual telescopic rod 701 moves with the tray 9, thereby increasing the supporting force of the tray 9. The hydraulic cylinder 8 is fixedly mounted on the inner side of the reinforcing rib 702. The reinforcing ribs 702 on the front and rear sides increase the supporting force of the hydraulic cylinder 8, thereby increasing stability.

[0032] Working principle: When using the device, place the device on a large channel steel guide rail, place the hull in sections on the pallet 9, and drive the roller body 201 to rotate through the motor 3, the first transmission mechanism 4 and the second transmission mechanism 5 to move the device on the large channel steel guide rail, thereby adjusting the position of the pallet 9, and through the electromagnetic slide rail 6, the electromagnetic slider 602 moves on the top of the shell 1, thereby fine-tuning the position of the pallet 9, and then the infrared sensor 10 is used to adjust the position of the hull on the pallet 9. The first sensor 11 and the second sensor 12 are fixedly installed inside the electromagnetic track 601 and the shell 1 respectively. When the infrared sensor 10 issues a prompt, the first sensor 11 or the second sensor 12 can automatically start the roller body 201 or the electromagnetic slider 602 to move, thereby adjusting the position of the pallet 9, so that the hull and the pallet 9 can be accurately aligned.

[0033] The above completes a series of operations of the hull segment closing hydraulic support with positioning function. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0034] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
