[0002] Ship is a general term for various vessels. A ship is a means of transportation that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. A ship is a man-made means of transportation that mainly operates in geographical waters. At present, when producing aluminum alloy ships, as the construction height of the ship increases, a lifting device is required to load the aluminum alloy plates of the welded ship.

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A ship aluminum alloy structure processing lifting device comprises a support base 1, a scissor-type lifting frame 2 is installed on the inner side of the support base 1, an adjusting screw 3 is rotatably connected to the inner side of the support base 1 and located at the bottom end of the scissor-type lifting frame 2, a lifting platform 4 is fixedly installed on the top of the scissor-type lifting frame 2, a limit frame 5 is fixedly installed on the top of the lifting platform 4, a moving frame 6 is installed on both the left and right ends of the limit frame 5, a protective plate 7 is fixedly connected to the opposite ends of the tops of two groups of moving frames 6, and a plurality of material support plates 8 are fixedly installed on the opposite sides of the two groups of protective plates 7, and also comprises:

[0026] The adjusting mechanism 9 is fixedly installed between the two groups of movable frames 6 , and the adjusting mechanism 9 is used for adjusting the distance between the two groups of movable frames 6 .

[0027] Firstly, movable seats 101 are fixedly installed at the four corners of the bottom of the support base 1, and the bottoms of multiple groups of movable seats 101 are rotatably connected with universal wheels 102. The bottoms of multiple groups of movable seats 101 and the outer sides of the universal wheels 102 are threadedly connected with support feet 103. The universal wheels 102 at the bottom of the movable seats 101 can drive the support base 1 to move, so that it can be moved and adjusted according to the loading location of the ship. When loading the aluminum alloy plate, the support feet 103 are rotated against the ground to fix the support base 1.

[0028] Furthermore, the front and rear ends of the adjusting screw 3 are rotatably connected to the supporting base 1, the bottom end of the scissor-type lifting frame 2 is threadedly connected to the adjusting screw 3 through the connecting sleeve 201, and the front side of the supporting base 1 is fixedly installed with a motor 301, and the driving end of the motor 301 is fixedly connected to the front end of the adjusting screw 3. When the aluminum alloy plates are fed, the aluminum alloy plates are placed on multiple groups of material support plates 8, and then the motor 301 is started to drive the adjusting screw 3 to rotate. Under the connection of the connecting sleeve 201, the lifting platform 4 on the scissor-type lifting frame 2 is raised upward, thereby lifting the aluminum alloy plates for feeding.

[0029] Then, a baffle 501 is fixedly connected to the middle of the front end of the limit frame 5, and the four corners of the bottom of the two groups of movable frames 6 are rotatably connected with movable wheels 601. When the aluminum alloy plate is placed on multiple groups of material pallets 8, the front end of the aluminum alloy plate is limited by the baffle 501, and when the distance between the two groups of movable frames 6 is adjusted by the adjustment mechanism 9, the movable wheels 601 assist in the movement to improve the stability of the adjustment.

[0030] Furthermore, the material support plate 8 is designed in an L-shaped structure, and multiple groups of material support plates 8 are evenly spaced on the inner side of the protective plate 7. The inner sides of the multiple groups of material support plates 8 are rotatably connected to multiple groups of rollers 801, and the outer sides of the multiple groups of material support plates 8 are provided with slide grooves 802. The inner side of the slide groove 802 is slidably connected to a first slide column 803, and the end of the first slide column 803 away from the slide groove 802 is rotatably connected to a connecting strip 804, and a pin 805 is inserted at the top of the connecting strip 804. Multiple groups of plug holes are provided at positions corresponding to the pin 805 on the inner side wall of the material support plate 8. When the aluminum alloy plate is placed on the material support plate 8, the distance between the two groups of movable frames 6 is first adjusted by the adjustment mechanism 9 according to the width of the aluminum alloy plate, so that the aluminum alloy plate can be placed on the two opposite groups. The left and right ends of the material support plate 8 are limited. After the aluminum alloy plate is placed, it is pushed forward to resist the baffle 501, so as to limit the front end of the material support plate 8, and then the first slide column 803 is slid backward to the rear end of the aluminum alloy plate according to the length of the aluminum alloy plate, and then the connecting strip 804 is rotated upward, and then the pin 805 is inserted into the socket at the rear end of the aluminum alloy plate, so that the rear end of the aluminum alloy plate is limited by the pin 805, so as to avoid the aluminum alloy plate from slipping during the loading process, which greatly improves the loading safety. At the same time, multiple groups of aluminum alloy plates are separated by multiple groups of material support plates 8 to facilitate separation during unloading. For subsequent unloading, you only need to pull out the pin 805, and then the aluminum alloy plate can be pulled out for unloading with the auxiliary rolling of the roller 801, which further greatly improves the loading efficiency.

[0031] Secondly, the adjusting mechanism 9 includes a bidirectional screw 901 rotatably connected to the middle of the inner side of the limit frame 5, the inner sides of the two groups of movable frames 6 are threadedly connected to the bidirectional screw 901 through a connecting block 902, the front and rear ends of the inner side of the limit frame 5 are fixedly connected with a slide bar 903, the front and rear ends of the two groups of movable frames 6 are slidably connected to the slide bar 903 through a slider 904, and the left end of the bidirectional screw 901 and the outer side of the limit frame 5 are fixedly connected with a crank 905. When the aluminum alloy plate is fed, the crank 905 is shaken according to the width of the aluminum alloy plate to drive the bidirectional screw 901 to rotate, and the two groups of movable frames 6 are driven to move relative to each other under the connection of the connecting block 902. At the same time, the distance between the two groups of movable frames 6 is stably adjusted under the connection and cooperation of the slider 904 and the slide bar 903 until the distance between the two groups of material pallets 8 can place the aluminum alloy plate.

[0032] Finally, a fixed gear 906 is fixedly connected to the outer side of the crank handle 905, and a fixed block 907 is fixedly connected to the outer side of the limit frame 5 and located on the back side of the fixed gear 906. A pull rod 908 is slidably connected to the inner side of the fixed block 907. The front end of the pull rod 908 is meshed with the fixed gear 906 through a fixed tooth block 909. A spring 910 is sleeved on the outer side of the pull rod 908 and located between the fixed tooth block 909 and the fixed block 907. The top of the fixed tooth block 909 is slidably connected to the fixed block 907 through a second sliding column 911. When adjusting the distance between the two groups of moving frames 6, first pull the pull rod 908 to release the fixed tooth block 909 from fixing the fixed gear 906, and then shake the crank handle 905 for adjustment. After the distance adjustment between the two groups of moving frames 6 is completed, the fixed tooth block 909 fixes the fixed gear 906 under the compression of the spring 910, thereby avoiding the crank handle 905 from rotating during loading and causing danger.

[0033] In this embodiment, the implementation scenario is specifically as follows: when loading the aluminum alloy plates used for the production of ships, first, the crank handle 905 is shaken according to the width of the aluminum alloy plate to drive the bidirectional screw 901 to rotate, and the two groups of movable frames 6 are driven to move relative to each other under the connection of the connecting block 902. At the same time, the distance between the two groups of movable frames 6 is stably adjusted under the connection and cooperation of the slider 904 and the slide bar 903 until the distance between the two groups of material pallets 8 can accommodate the aluminum alloy plates, and then multiple aluminum alloy plates are placed layer by layer on the material pallet 8 to limit the left and right ends. After the aluminum alloy plates are placed, they are pushed forward against the baffle 501, thereby limiting the front end of the material pallet 8, and then the first slide column 803 is slid backward to the rear end of the aluminum alloy plate according to the length of the aluminum alloy plate, and then the connecting strip 804 is rotated upward, and then the pin 805 is inserted into the rear end of the aluminum alloy plate. In the socket, the rear end of the aluminum alloy plate is limited by the pin 805, so as to prevent the aluminum alloy plate from slipping during the loading process, greatly improving the loading safety, and at the same time, the multiple groups of aluminum alloy plates are separated by multiple groups of material support plates 8 to facilitate separation during unloading. For subsequent unloading, it is only necessary to pull out the pin 805, and then the aluminum alloy plate can be pulled out for unloading under the auxiliary rolling of the roller 801. After the aluminum alloy plate is placed on the multiple groups of material support plates 8, the motor 301 is started to drive the adjusting screw 3 to rotate, and the lifting platform 4 on the scissor-type lifting frame 2 is raised upward under the connection of the connecting sleeve 201, so as to lift the aluminum alloy plate for loading. The whole operation process is simple and convenient. Compared with the existing ship aluminum alloy structure processing lifting device, the utility model can improve the overall safety and loading efficiency of the ship aluminum alloy structure processing lifting device through design.
