Description

Technical Field

[0001] The utility model relates to the technical field of marine steel structure electric welding equipment, in particular to a tooling fixture for marine steel structure electric welding. Background Art

[0002] Marine steel structure refers to a system of steel components used to build, support and maintain various facilities and structures in the marine environment. Common types and components of marine steel structures include steel frames, etc. Steel frames are used to build support frames for large structures such as offshore platforms, offshore bridges, and offshore wind power foundations. Steel frames are usually welded from steel of various shapes and have good load-bearing capacity and wind and wave resistance. Rectangular steel is a type of steel with a rectangular cross-sectional shape. It is usually processed by hot rolling or cold drawing and has a rectangular cross-section, that is, it presents a rectangular or square shape in cross section. However, some rectangular steels are relatively large and heavy. After the steel is hoisted onto the gantry using lifting equipment, and then the lifting equipment is untied from the steel, if the welding position of the steel is not found to be aligned in time, not only is it necessary to use the lifting equipment for additional operations, but the steel also needs to be tied to the lifting equipment again, which will increase the complexity and difficulty of the operation.

[0027] like Figure 1-7 As shown, the utility model proposes a fixture for electric welding of marine steel structures, including a support platform 1 and a first steel material 13 and a second steel material 14 to be welded arranged on the support platform 1. The upper surface of the support platform 1 is fixedly connected with a plurality of baffles 12 for resisting the first steel material 13. The baffles 12 are used to clamp the second steel material 14 to prevent the second steel material 14 from sliding randomly during welding. The lower surface of the support platform 1 is fixedly connected with a base frame 4 for support, and also includes: a groove 11 opened on the support platform 1; a clamping mechanism installed in the groove 11 for clamping the second steel material 14 to move, and then quickly aligning the second steel material 14 with the first steel material 13 at the position where welding is required.

[0028] Furthermore, the clamping mechanism includes a pair of slide rails 2 fixedly connected to the upper surface of the groove 11, each of which is provided with an adjustment groove 21, and a U-shaped bracket 3 is provided on the slide rail 2. After the U-shaped bracket 3 supports the first steel material 13, the height of the first steel material 13 is at the same level as the second steel material 14 on the support platform 1. A motor cover 35 for covering the second motor 34 is fixedly connected to one end of the U-shaped bracket 3 close to the second motor 34. The motor cover 35 is a shell for covering the motor, and the motor cover 35 can effectively protect the internal components of the second motor 34 from being damaged by the external environment, such as dust, water vapor, chemicals, etc., thereby extending the service life of the motor. A pair of limiting sliders 36 for sliding in the adjusting groove 21 are fixedly connected to the bottom of the U-shaped bracket 3, a support plate 15 is fixedly connected to the outer wall of the support platform 1, and a first motor 16 is fixedly connected to the upper surface of the support plate 15. The upper surface of the groove 11 is located in the middle of the slide rail 2 and is fixedly connected to a first support seat 17 and a second support seat 19. The middle part of the first support seat 17 and the second support seat 19 is rotatably connected to a first screw rod 18, and one end of the first screw rod 18 close to the first motor 16 moves through the first support seat 17 and is fixedly connected to the output shaft of the first motor 16.

[0029] Furthermore, the clamping mechanism also includes a slide groove 31 provided in the U-shaped bracket 3, a spiral connection block 37 spirally connected to the first spiral rod 18 is fixedly connected to the bottom of the U-shaped bracket 3, a second motor 34 is provided on the U-shaped bracket 3, a second spiral rod 39 is provided inside the slide groove 31, one end of the second spiral rod 39 is movably passed through the U-shaped bracket 3 and is fixedly connected to the output shaft of the second motor 34, a supporting slider 32 spirally connected to the second spiral rod 39 is slidably connected inside the slide groove 31, and a ball is provided at the bottom of the supporting slider 32, and the function of the ball is to make the supporting slider 32 slide more smoothly inside the slide groove 31. The function of the supporting slider 32 is to hold the second steel material 14. A limiting groove 38 is provided on the supporting slider 32, and a supporting slider 33 for supporting the sliding of the limiting groove 38 is fixedly connected inside the slide groove 31, and the function of the supporting slider 33 is to keep the supporting slider 32 in a horizontal direction when sliding inside the slide groove 31.

[0030] In this embodiment, when the fixture for electric welding of marine steel structures is needed, it is only necessary to first use the lifting equipment to place the first steel material 13 on the upper surface of the support platform 1 and against the baffle 12, and then use the lifting equipment to place the second steel material 14 inside the U-shaped bracket 3, and Figure 1Place it. Then, when it is necessary to place one end of the second steel material 14 against the position where it is welded to the first steel material 13, it is only necessary to start the first motor 16 on the support plate 15. The output shaft of the first motor 16 passes through the first support seat 17 and drives the first screw rod 18 to rotate. The end of the first screw rod 18 away from the first support seat 17 rotates with the support of the second support seat 19. Since the first screw rod 18 is spirally connected to the spiral connection block 37, the first screw rod 18 drives the spiral connection block 37 and the U-shaped bracket 3 on the top of the spiral connection block 37 to slide along the adjustment groove 21 in the slide rail 2 until the end of the second steel material 14 close to the first steel material 13 is aligned with the position where it is welded to the first steel material 13. At this time, start the second motor 34 in the motor cover 35, and the second motor 34 drives the second screw rod 39 to rotate inside the slide groove 31. Since the second spiral rod 39 is spirally connected to the supporting slider 32, the supporting slider 32 drives the second steel material 14 thereon to move in the direction of the first steel material 13, and the supporting slider 33 is inserted into the limiting groove 38 to support the sliding direction of the supporting slider 32 in the horizontal direction. Finally, the supporting slider 32 drives the second steel material 14 thereon to press against the first steel material 13, and the position where the first steel material 13 and the second steel material 14 contact is the welding position, and the first steel material 13 and the second steel material 14 are perpendicular to each other.
