Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a ship plate frame welding device. Background Art

[0002] Welding is an important link in shipbuilding and a key factor in determining the quality of the hull. At present, the splicing, segmentation and closure of large ships are all achieved through welding. In the existing technology, the ship plates fixed on the hull are generally welded manually through welding equipment on a lifting platform. However, since the lifting platform can only be raised and lowered, it is inconvenient to weld the ship plates.

[0003] Chinese patent CN202010711252.0 discloses an automatic welding platform for the bottom surface of a ship section, comprising a flat base, a moving mechanism arranged at the bottom of the base, a fixing mechanism arranged in the middle of the base, a lifting plate arranged above the base, a lifting mechanism arranged between the lifting plate and the base and driving the lifting plate to lift and lower, and a welding mechanism arranged on the lifting plate; The automatic welding platform for the bottom surface of a ship section solves the technical problem of the inconvenience of moving the lifting platform through a moving mechanism, improves welding accuracy, and improves welding efficiency, but it can only weld the bottom surface of the ship, and cannot weld two ship plates that need to be connected in the middle section of the side of a large ship. In the prior art, When welding ship plates, the ship plates are first fixed on the hull, and then welding is performed at the positions where two adjacent ship plates need to be welded by welding equipment. The welding equipment is placed on a platform, and the equipment is suspended on the side of the hull by steel cables. The platform is then driven to move along the steel cables by a lifting mechanism, so that the platform is lifted and lowered on the side of the hull, thereby welding two adjacent ship plate joints on the side of the hull. However, it is inconvenient to fix the platform to the ship plates during welding, which makes it easy for the ship plates to shift during welding, resulting in insufficient welding accuracy. At the same time, since the ship plates are large, when welding the ship plates at high places, the falling of welding slag during welding may cause safety accidents, which increases the difficulty of operation.

DETAILED DESCRIPTION

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1-13 As shown, this application provides:

[0041] A ship plate frame welding device comprises a welding frame 1 and a lifting mechanism 1a, a driving mechanism 1b and a welding platform 2 arranged on the welding frame 1. The welding frame 1 is a rectangular frame structure with a hollow middle portion. The welding frame 1 is arranged in a vertical state. The lifting mechanism 1a is located at the top of the welding frame 1. The welding platform 2 is provided with a mounting plate 2a, a first slide rail 2a1, a collecting mechanism 3, a translation assembly 2b, a second slide rail 2c, a translation frame 2d, a first rotary drive motor 2d1, a third slide rail 2d2, a first slider 2d3 and a welding gun 2d4. The welding platform 2 can slide along the length direction of the welding frame 1. The welding platform 2 is transmission-connected to the driving mechanism 1b. The mounting plate 2a is located on one side below the welding platform 2. The first slide rail 2a1 is horizontally arranged on the mounting plate 2a. The collecting mechanism 3 is slidably located on the first slide rail 2a1. The translation assembly 2b and the second slide rail 2c are both arranged at the bottom of the welding platform 2, and the second slide rail 2c Parallel to the first slide rail 2a1, the translation frame 2d is slidably located on the second slide rail 2c, and the translation frame 2d is transmission connected to the translation assembly 2b, the collecting mechanism 3 is fixedly connected to the translation frame 2d at one end close to the mounting plate 2a, and a retractable shielding assembly 3a is provided on the collecting mechanism 3, the first rotation drive motor 2d1 and the third slide rail 2d2 are both arranged on the translation frame 2d, the first slider 2d3 is slidably located on the third slide rail 2d2, the sliding direction of the first slider 2d3 is perpendicular to the sliding direction of the translation frame 2d, the first rotation drive motor 2d1 is fixedly connected to the end of the translation frame 2d away from the mounting plate 2a, the first slider 2d3 is transmission connected to the first rotation drive motor 2d1, the welding gun 2d4 is fixedly connected to the first slider 2d3, the shielding assembly 3a is transmission connected to the first slider 2d3, and electromagnets 1c are provided on the top and bottom plates 3a7 of the welding frame 1 and the mounting plate 2a of the welding platform 2.

[0042] Based on the above embodiments, the technical problem that the present application intends to solve is how to improve the welding accuracy of welding equipment when welding ship plates, and collect welding slag during the welding process. To this end, the present application suspends the welding frame 1 on the side of the ship plate through a steel cable, and then adjusts the position of the welding frame 1 through the lifting mechanism 1a, and then adsorbs the ship plate through the electromagnets 1c at the top and bottom of the welding frame 1, so that the welding frame 1 is fixed to the ship plate. At this time, the welding platform 2 is driven to move by the driving mechanism 1b. Since the welding frame 1 is arranged in a vertical direction, the welding platform 2 is moved along the length direction of the welding frame 1, so that the welding gun 2d4 on the welding platform 2 is used to weld the joints between two adjacent ship plates. The welding frame 1 is adsorbed and fixed to ensure the accuracy of the movement of the welding platform 2, and it is not easy to deviate. When the position needs to be changed, the welding platform 2 is moved by the welding platform 2. The electromagnet 1c on the mounting plate 2a is fixed to the ship plate. At this time, the lifting mechanism 1a and the driving mechanism 1b are driven simultaneously, so that the welding platform 2 drives the welding frame 1 to move when it is fixed, so that the welding frame 1 can maintain the same direction and cannot deviate from the position, ensuring the accuracy of the moving path of the welding platform 2 when it is fixed to the ship plate next time. The welding frame 1 and the welding platform 2 are alternately fixed to the ship plate through the electromagnet 1c, so that they can accurately move and weld according to the preset path, thereby improving the welding accuracy; through the setting of the translation component 2b and the second slide rail 2c, the welding frame 1 can also be horizontally welded to the ship plate when it is fixed, thereby improving the adaptability of the equipment; through the first The setting of the rotary drive motor 2d1 and the first slider 2d3 enables the first slider 2d3 to drive the welding gun 2d4 to slide on the translation frame 2d. When the welding gun 2d4 moves to the outside of the welding platform 2, the ship plate is welded. When the mounting plate 2a of the welding platform 2 needs to adsorb the ship plate, the welding gun 2d4 moves to the bottom of the translation frame 2d, thereby reducing the distance between the mounting plate 2a and the ship plate, so as to facilitate the adsorption of the ship plate through the electromagnet 1c on the mounting plate 2a; the setting of the collection mechanism 3 fixedly connected to the translation frame 2d enables the collection mechanism 3 to move with the translation frame 2d, thereby driving the shielding component 3a to move with the translation frame 2d through the collection mechanism 3, so as to achieve the above-mentioned effect. In order to collect the welding slag that falls off during work, the first rotating drive motor 2d1 drives the movement of the first slider 2d3, thereby driving the welding gun 2d4 fixedly connected to the first slider 2d3. When the welding gun 2d4 moves to the outside of the welding platform 2 to weld the ship plate, the movement of the first slider 2d3 drives the opening of the shielding component 3a, thereby facilitating the shielding component 3a to move to the side of the welding gun 2d4 to prevent the welding slag from falling off during the welding process, thereby causing a safety accident. Finally, the welding slag is collected by the collecting device. The shielding component 3a is retractable to reduce the distance between the mounting plate 2a and the ship plate, thereby facilitating the adsorption of the electromagnet 1c and the ship plate.

[0043] like Figure 6 , Fig. 9 and Fig.13 As shown, further:

[0044] There are two first slide rails 2a1, and the two first slide rails 2a1 are arranged in parallel on the mounting plate 2a. The collecting mechanism 3 includes a sliding frame 3b, and the sliding frame 3b is a rectangular frame. A connecting plate 3b1 in a horizontal state is arranged on the top of the sliding frame 3b. The connecting plate 3b1 passes through the first slide rail 2a1 above the mounting plate 2a and is fixedly connected with the top of the translation frame 2d. Four pulleys 3b2 are arranged on the side of the sliding frame 3b close to the mounting plate 2a. The four pulleys 3b2 are grouped into two, and the two groups of pulleys 3b2 are respectively located at the top and bottom of the sliding frame 3b, and the two groups of pulleys 3b2 are respectively slidably located on the two first slide rails 2a1, and the centers of all the pulleys 3b2 are provided with mounting holes 3b3. The shielding component 3a is telescopically located on the sliding frame 3b.

[0045] Based on the above embodiments, the technical problem that the present application intends to solve is how the collecting mechanism 3 is fixedly connected to the translation frame 2d and slides on the first slide rail 2a1. To this end, the present application sets a rectangular slide frame 3b and a pulley 3b2 so that the slide frame 3b can slide along the direction of the first slide rail 2a1. The setting of two slide rails and two sets of pulleys 3b2 makes the sliding of the slide frame 3b more stable, and makes the connection between the slide frame 3b and the mounting plate 2a more firm, thereby improving the stability of the operation of the collecting mechanism 3.

[0046] like Figure 4-9 , Fig.11 and Fig.12 As shown, further:

[0047] The shielding assembly 3a includes a telescopic frame 3a1, which is a rectangular frame body. The volume of the telescopic frame 3a1 is smaller than that of the sliding frame 3b. The top of the telescopic frame 3a1 is flush with the top of the sliding frame 3b. The telescopic frame 3a1 is provided with four guide rods 3a2 which are all arranged in a horizontal state, and the four guide rods 3a2 are respectively sleeved in four mounting holes 3b3 of the sliding frame 3b. A limit plate 3a3 is provided on the end of the four guide rods 3a2 away from the telescopic frame 3a1, and a connecting rod 3a4 is fixedly connected between two limit plates 3a3 located on the same vertical line. Wing plates 3a5 matching the connecting plates 3b1 are provided on both sides of the first sliding block 2d3. Elastic members 3a6 are sleeved on the four guide rods 3a2, and the elastic members 3a6 are located between the limit plates 3a3 and the pulley 3b2 of the sliding frame 3b.

[0048] Based on the above embodiments, the technical problem that the present application intends to solve is how to connect the shielding assembly 3a to the first slider 2d3 in a transmission manner. To this end, the present application drives the movement of the wing plates 3a5 on both sides thereof through the movement of the first slider 2d3, and the wing plates 3a5 abut against the connecting rod 3a4 on the telescopic frame 3a1, thereby driving the connecting rod 3a4 to move along the direction of the third slide rail 2d2, thereby driving the movement of the limit plate 3a3 on the same vertical line of the displacement. At this time, the limit plate 3a3 will squeeze the elastic member 3a6, causing the elastic member 3a6 to contract, and the movement of the limit plate 3a3 drives the guide rod 3a2 to move along the axis of the mounting hole 3b3. The movement of the four guide rods 3a2 drives the telescopic frame 3a1 to move along the axis of the mounting hole 3b3, thereby lengthening the distance between the telescopic frame 3a1 and the sliding frame 3b, thereby In order to match the movement of the welding gun 2d4 on the first slider 2d3, when the welding platform 2 needs to adsorb the ship plate, the welding gun 2d4 is driven by the first slider 2d3 to move to the bottom of the welding platform 2. At this time, the connecting rod 3a4 loses the support of the wing plate 3a5 that it abuts, so that the elastic member 3a6 can open and reset, thereby driving the connecting rod 3a4 to return to its initial position. At this time, the connecting rod 3a4 drives the limit plate 3a3, the limit plate 3a3 drives the guide rod 3a2, and the guide rod 3a2 drives the telescopic frame 3a1, thereby reducing the distance between the telescopic frame 3a1 and the sliding frame 3b, thereby reducing the distance between the mounting plate 2a and the ship plate, thereby facilitating the electromagnet 1c on the mounting plate 2a to adsorb the ship plate.

[0049] like Figure 4-9 and Fig.12 As shown, further:

[0050] The shielding assembly 3a also includes a retractable base plate 3a7 and a plurality of U-shaped frames 3a8. The bottoms of the telescopic frame 3a1 and the sliding frame 3b are respectively provided with a first rotating shaft 3a9 and a second rotating shaft 3a10 which are arranged in a horizontal state. The two ends of the base plate 3a7 are respectively sleeved on the first rotating shaft 3a9 and the second rotating shaft 3a10. The plurality of frames 3a8 are slidably nested with each other from large to small according to their sizes. The plurality of frames 3a8 form a retractable material blocking channel 3a11 with an opening at the bottom. The two ends of the material blocking channel 3a11 are respectively fixedly connected to the telescopic frame 3a1 and the sliding frame 3b. The base plate 3a7 is located at the bottom of the material blocking channel 3a11.

[0051] Based on the above embodiments, the technical problem that the present application intends to solve is how to extend and retract the shielding component 3a to shield the welding slag. To this end, the present application arranges multiple U-shaped frames 3a8 that are slidably nested together according to their sizes from large to small, so that when the telescopic frame 3a1 is driven by the first slider 2d3, it will drive the movement of the blocking channel 3a11, so that the multiple U-shaped frames 3a8 slide against each other, thereby matching the distance between the telescopic frame 3a1 and the sliding frame 3b. At the same time, the movement of the telescopic frame 3a1 drives the movement of the first rotating shaft 3a9 at its bottom, so that the bottom plate 3a7 also extends and retracts to match the distance between the first rotating shaft 3a9 and the second rotating shaft 3a10. The top of the telescopic frame 3a1 is flush with the top of the sliding frame 3b, and the volume of the telescopic frame 3a1 is smaller than the sliding frame 3b, so that the first rotating shaft 3a9 and the second rotating shaft 3a10 at the bottom of the telescopic frame 3a1 and the sliding frame 3b are not on the same horizontal line, so that the bottom plate 3a7 is tilted, so that the welding gun 2d4 is blocked by the material blocking channel 3a11 after the welding slag is scattered and finally falls to the bottom plate 3a7. It can slide along the bottom plate 3a7 due to the action of gravity, so that the welding slag finally falls into the welding platform 2, thereby reducing the occurrence of safety accidents caused by the high-temperature welding slag.

[0052] like Figure 6 , Fig.10 and Fig.12 As shown, further:

[0053] The collecting mechanism 3 also includes a collecting bag 3c, which is made of flexible material. A rectangular connecting frame 3c1 is arranged at the opening of the collecting bag 3c, and second sliders 3c2 are arranged on both sides of the connecting frame 3c1. A discharging slide rail 3c3 matching the second slider 3c2 is arranged on the mounting plate 2a, and the discharging slide rail 3c3 is parallel to the first slide rail 2a1. The ends of the two second sliders 3c2 away from the collecting bag 3c pass through the discharging slide rail 3c3 and are fixedly connected to the bottom of the sliding frame 3b, and the inner wall of the discharging slide rail 3c3 is arranged at an angle.

[0054] Based on the above embodiments, the technical problem that the present application intends to solve is how to collect the welding slag sliding into the welding platform 2. To this end, the present application arranges the collecting bag 3c and the second slider 3c2 so that the collecting bag 3c can move with the sliding frame 3b, and the inner wall of the unloading slide rail 3c3 is arranged to be inclined so that the welding slag will not get stuck on the unloading slide rail 3c3 when it moves onto the unloading slide rail 3c3 through the bottom plate 3a7, so that the welding slag can move into the collecting bag 3c along the inner wall of the unloading slide rail 3c3, and finally the welding slag is collected by the collecting bag 3c.

[0055] like Fig.11 As shown, further:

[0056] The translation frame 2d includes a fixed plate 2d5, a driving block 2d6, a first screw rod 2d7 and two support plates 2d8. The driving block 2d6 is slidably located on the second slide rail 2c. The fixed plate 2d5 is fixedly connected to the bottom of the driving block 2d6 in a horizontal state. The two support plates 2d8 are respectively located at both ends of the fixed plate 2d5 in the length direction. The first screw rod 2d7 is fixedly connected between the two support plates 2d8 in a horizontal state. The axis of the first screw rod 2d7 is parallel to the third slide rail 2d2. The first screw rod 2d7 passes through the first slider 2d3 and is threadedly matched with it. The first rotation drive motor 2d1 is fixedly connected to the support plate 2d8 on the side of the fixed plate 2d5 away from the mounting plate 2a. The output shaft of the first rotation drive motor 2d1 passes through the support plate 2d8 and is fixedly connected to the first screw rod 2d7. The welding gun 2d4 is sleeved on the slider, and the mounting plate 2a is provided with an avoidance groove 2a2 that matches the welding gun 2d4.

[0057] Based on the above embodiments, the technical problem that the present application intends to solve is how the slider drives the welding gun 2d4 to move. To this end, the present application drives the rotation of the first screw 2d7 fixedly connected to the first rotary drive motor 2d1 through the output shaft thereof, and the rotation of the first screw 2d7 drives the movement of the first slider 2d3 threadedly matched therewith, so that the first slider 2d3 slides along the third slide rail 2d2, thereby driving the movement of the welding gun 2d4.

[0066] Based on the above embodiments, the technical problem that the present application intends to solve is how to facilitate the sliding of the welding frame 1 and the welding platform 2 on the ship board. To this end, the present application sets the universal wheel 1d so that when the welding frame 1 and the welding platform 2 are alternately adsorbed on the ship board, the friction between the welding frame 1 or the welding platform 2 and the ship board can be reduced, and the sliding is facilitated. The setting of the elastic connection facilitates the universal wheel 1d to match the distance between the ship board and the welding platform 2 or the mounting plate 2a of the welding frame 1.

[0067] like Figure 5 and Fig.13As shown, further:
