Description

Technical Field

[0001] The invention relates to the technical field of ship welding, and in particular to an auxiliary platform for ship welding provided with a protective component. Background Art

[0002] As the main means of transportation on water, ships have a huge number of parts. Their sizes and performances vary according to their different transportation functions. Whether it is a huge ship or a small ship, its frame columns are made of steel components, most of which are processed by riveting, welding and other splicing and fixing methods. These components have different shapes, and corresponding welding auxiliary platforms are usually required during welding.

[0003] However, in actual operation, the existing auxiliary platforms for ship welding mostly place steel structure parts on a horizontal operating table, which can only meet the welding requirements of steel structure parts when they are placed horizontally. However, in the actual welding process, steel structure parts sometimes need to be welded in an inclined manner, which makes it difficult to meet the welding requirements of steel structure parts and reduces the welding efficiency. At the same time, due to the wide variety of ship parts and their different shapes, there are often some parts with uneven single sides. In this way, when positioning before welding, when the traditional positioning clamp is clamping the uneven side, when the clamp just hits the inclined surface of the concave or convex block, it is easy to cause the clamping force point to be unstable, which leads to loose clamping and even part displacement, affecting the subsequent welding process. In addition, when the traditional auxiliary platform for ship welding is not in use for a long time, a lot of dust will accumulate on the surface of its operating table. In this way, in the subsequent welding work, some dust particles are easy to adhere to the welding material or weld, resulting in defects such as pores and slag inclusions during the welding process, thereby reducing the quality and strength of the welded joint. In view of the above problems, the present invention document proposes an auxiliary platform for ship welding provided with a protective component. Summary of the invention

[0018] Compared with the prior art, the present invention provides an auxiliary platform for ship welding provided with a protective component, which has the following beneficial effects:

[0019] 1. The auxiliary platform for ship welding with protective components is provided with an operating table, a motor, a guide block and a slide groove. The motor drives the operating table to rotate together, and the guide block slides along the slide groove at the same time, which plays a role of limiting and guiding the operating table. The rotation of the operating table can drive the weldment placed thereon to deflect together, so as to facilitate the adjustment of the placement angle of the weldment, so as to meet the welding requirements of different steel structure parts and ensure the welding efficiency.

[0020] 2. The auxiliary platform for ship welding with protective components is provided with a protective curtain, a pull rod and a connecting rod. When not in use, the motor drives the operating table to rotate ninety degrees, which is convenient for storing the operating table and the clamping components thereon. At the same time, the motor will also drive the connecting rod to rotate together, and then pull the protective curtain through the pull rod until the protective curtain is fully unfolded. While the operating table is vertically stored, the top of the operating table can also be shielded and protected to reduce dust accumulation on the operating table, thereby preventing a large amount of dust particles from adhering to the welding material or weld during welding work, reducing the generation of pores and slag inclusions during welding, and improving the quality and strength of the welded joint.

[0021] 3. The auxiliary platform for ship welding with a protective component is equipped with a placement block, a screw, a moving block, a gear, a rack and a positioning block, so that the weldment is placed under the placement block, and then the moving block and the gear are driven to move together by the screw. The gear first pushes the two racks to move together, and then drives the two positioning blocks to move together. When the surface of the weldment is uneven, one of the positioning blocks will first contact the weldment. At this time, the positioning block and the corresponding rack will be stressed, and finally the two racks will be staggered through the meshing transmission until the other positioning block also contacts the weldment, so that the press limit of the weldment is more stable, avoiding the unstable force point, and then avoiding loose clamping or even part displacement, ensuring the normal subsequent welding.

[0022] 4. The auxiliary platform for ship welding with protective components is provided with a mounting block, a clamping block, a rotating rod, a curtain and a slot. The mounting block is pulled to gradually unfold the curtain, and the rotating rod is rotated at the same time until the clamping block is engaged with the slot. At this time, the curtain will completely cover the opening of the installation frame, thereby further shielding and protecting the operating table, reducing dust accumulation, and preventing a large amount of dust particles from adhering to the welding material or weld during welding, thereby improving the quality and strength of the welded joint.

[0052] In the present invention, the closing mechanism 6 includes a first vertical rod 601 and a second vertical rod 602, the two ends of one side of the bottom plate 1 are respectively fixedly connected with the first vertical rod 601 and the second vertical rod 602, and the first vertical rod 601 and the second vertical rod 602 are both fixedly connected to the placement frame 2, the interior of the first vertical rod 601 is rotatably connected with a rotating rod 605, a blind 606 is wound on the rotating rod 605, a mounting block 603 is engaged with the first vertical rod 601, one end of the blind 606 is fixedly connected to the rotating rod 605, and the other end is fixedly connected to the mounting block 603, a second spring 607 is provided on the rotating rod 605, one end of the second spring 607 is fixedly connected to the rotating rod 605, and the other end is fixedly connected to the interior of the first vertical rod 601, a plurality of clamping blocks 604 are fixedly connected to the mounting block 603, a plurality of clamping grooves 608 are provided on the second vertical rod 602, and a damping pad 609 is provided on the clamping groove 608, by setting the first vertical rod 6 01, second vertical pole 602, mounting block 603, clamping block 604, rotating rod 605, blind 606, second spring 607, clamping slot 608 and damping pad 609. When the device is not in use, the mounting block 603 on the first vertical pole 601 can be pulled, and the mounting block 603 moves to drive the blind 606 to gradually unfold. The rotating rod 605 rotates at the same time, and the second spring 607 contracts at the same time until the clamping block 604 on the mounting block 603 is engaged in the clamping slot 608 on the second vertical pole 602. The damping pad 609 will increase the corresponding friction resistance to facilitate the limiting of the clamping block 604. At this time, the blind 606 will completely block the opening of the placement frame 2, thereby further shielding and protecting the operating table 301, reducing dust accumulation, and avoiding a large amount of dust particles from adhering to the welding material or weld during welding, thereby improving the quality and strength of the welded joint.

[0053] Working principle: During actual welding, the corresponding parts can be placed on the operating table 301, and the two ends of the weldment can be placed under the two placement blocks 501 on the same side. Then, the operator manually rotates the hand wheel 502, and the hand wheel 502 rotates to drive the screw rod 503 to rotate. As the screw rod 503 rotates, it will drive the moving block 504 to continuously move inside the placement block 501, and the movement of the placement block 501 drives the gear 505 to move together. As the gear 505 moves, it will first push the two racks 506 to move together, and then drive the two positioning blocks 507 to move together, until the positioning block 507 is pressed against the weldment. The weldment is pressed and limited, and when the surface of the weldment is uneven, one of the positioning blocks 507 will first contact the weldment. At this time, the positioning block 507 and the corresponding rack 506 will be displaced relative to the placement block 501 by force, and the gear 505 will be driven at the same time. The rotation of the gear 505 will drive the other rack 506 to move, causing the two racks 506 to be staggered and displaced until the other positioning block 507 also contacts the weldment, thereby making the weldment pressed and limited more stable, avoiding the instability of the force point, and further avoiding loose clamping or even part displacement, thereby ensuring the normal subsequent welding.

[0054] As needed, the motor 302 can be connected to a power source, and the motor 302 rotates to drive the operating table 301 to rotate together. At the same time, the guide block 303 slides along the slide groove 304 to play a role of limiting and guiding the operating table 301. As the operating table 301 rotates, the weldment placed thereon will be driven to deflect together, thereby facilitating the adjustment of the placement angle of the weldment according to actual needs, thereby meeting the welding requirements of different steel structure parts and ensuring welding efficiency.

[0055] When the device is not in use, the motor 302 drives the operating table 301 to rotate 90 degrees until the operating table 301 is in a vertical state, so that the operating table 301 and the clamping components thereon can be stored conveniently. Furthermore, as the motor 302 rotates, the connecting rod 407 is also driven to rotate together, so that the connecting rod 407 slides along the sliding frame 402. As the connecting rod 407 rotates, the pull rod 405 is also driven to move together, and then the protective curtain 404 is pulled by the pull rod 405, so that the protective curtain 404 04 is gradually unfolded along the trajectory of the sliding frame 402, and the connecting shaft 403 rotates accordingly, and the first spring 406 contracts at the same time until the protective curtain 404 is fully unfolded. When the operating table 301 is vertically stored, the upper part of the operating table 301 can also be shielded and protected to reduce dust accumulation on the operating table 301, so as to avoid a large amount of dust particles from adhering to the welding material or the weld during the welding work, reduce the occurrence of pores and slag inclusions during the welding process, and improve the quality and strength of the welded joint.

[0056] Furthermore, the mounting block 603 on the first vertical pole 601 can be pulled, and the movement of the mounting block 603 drives the blind 606 to gradually unfold, and the rotating rod 605 rotates at the same time, and the second spring 607 contracts at the same time until the block 604 on the mounting block 603 is engaged in the slot 608 on the second vertical pole 602, and the damping pad 609 will increase the corresponding friction resistance to facilitate the limiting of the block 604. At this time, the blind 606 will completely block the opening of the mounting frame 2, thereby further shielding and protecting the operating table 301, reducing dust accumulation, and avoiding a large amount of dust particles from adhering to the welding material or weld during welding, thereby improving the quality and strength of the welded joint.

[0057] In addition, during the welding process, some welding slag will be generated. After falling, the welding slag will gradually fall into the collection frame 701. After a period of time, the user can manually hold the handle 702 and pull out the collection frame 701, which is convenient for centralized processing of the collected welding slag.
