Description

Technical Field

[0001] This utility model relates to the field of electrode shell assembly technology, specifically to the electrode shell welding trolley fixing plate. Background Technology

[0002] In modern industrial production, the electrode shell is a core component of critical equipment such as electric arc furnace steelmaking, and its welding quality directly affects the operational stability and service life of the equipment. Electrode shell welding requires welds with high strength, sealing properties, and uniformity to ensure that leaks and fractures do not occur under harsh operating conditions such as high temperature and high pressure.

[0003] like Figure 1 As shown, a cross-sectional view of the electrode shell is presented. The electrode shell is a cylindrical structure formed by 16 long and arc-shaped side plates 1. There are also 16 stiffening plates 2 between the ends of adjacent side plates 1. The welding connection is completed after the stiffening plates 2 and the ends of the side plates 1 are bent. At present, the electrode shell welding is mainly carried out by manual welding and semi-automatic welding equipment.

[0004] The existing welding method involves first assembling the side plates and stiffeners on an electrode housing support consisting of a pair of discs and a frame, and then welding is completed while assembling. The ends of the side plates need to rest on the edges of the discs, and the stiffeners are inserted into the corresponding slots on the discs. However, the edges of the discs and the gaps between the disc slots lack limiting and fixing structures, which causes the side plates and stiffeners to move and misalign during welding, affecting welding stability and welding quality. Currently, most of the welding is done manually, which is labor-intensive and the limiting may not be accurate. Utility Model Content

[0005] The purpose of this invention is to provide a fixing plate for an electrode shell welding trolley.

[0006] This utility model is implemented by the following technical solution: The electrode shell welding trolley fixing plate includes a rectangular base, a fixed trapezoidal frame, and a movable trapezoidal frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 2 , Figure 3 , Figure 4 As shown, the electrode shell welding trolley fixing plate includes a rectangular base 1, a fixed trapezoidal frame 2, and a movable trapezoidal frame 3. The bottom of the fixed trapezoidal frame 2 is fixed to the top of the rectangular base 1, and the bottom of the movable trapezoidal frame 3 is slidably connected to the top of the rectangular base 1 via a slide rail 4. The tops of the fixed trapezoidal frame 2 and the movable trapezoidal frame 3 are respectively rotatably connected to rotating shafts 5 in the same axis. Two longitudinal turntables 6 are provided between the two rotating shafts 5, and the centers of the two turntables 6 are respectively fixed to the ends of the adjacent rotating shafts 5. A side plate 1 is placed between the two turntables 6, with the end of the side plate 1 resting on the edge of the turntable 6. While building and welding the side plate 1, the two turntables 6 are also connected. When building the next side plate 1, the two turntables 6 can be rotated at the same time to change their positions, which facilitates the building of the next side plate 1. The moving trapezoidal frame 3 moves towards the fixed trapezoidal frame 2. The distance between the moving trapezoidal frame 3 and the fixed trapezoidal frame 2 can be adjusted. The moving trapezoidal frame 3 moves away from the fixed trapezoidal frame 2, which facilitates the removal of the electrode shell from the two turntables 6.

[0019] The slide rail 4 includes a pair of slide grooves 4.1 fixed on the top of the rectangular base 1, and a pair of sliders 4.2 fixed on the bottom of the movable trapezoidal frame 3. The longitudinal section of the sliders 4.2 is dovetail-shaped. The slide grooves 4.1 match the sliders 4.2, and the sliders 4.2 slide within the slide grooves 4.1. The movement of the movable trapezoidal frame 3 is achieved by the sliders 4.1 sliding within the slide grooves 4.2. The dovetail shape prevents them from coming off.

[0020] A horizontal hydraulic cylinder 9 is also provided on one side of the movable trapezoidal frame 3 at the top of the rectangular chassis 1. The fixed end of the horizontal hydraulic cylinder 9 is fixed to the top of the bottom of the movable trapezoidal frame 3, and the telescopic end of the horizontal hydraulic cylinder 9 is fixed to the top of the rectangular chassis 1. The telescopic movement of the horizontal hydraulic cylinder 9 provides power for the movement of the movable trapezoidal frame 3, and the telescopic stroke can also limit the movement distance.

[0021] The turntable 6 has multiple elongated slots 6.1 spaced along the circumference from the edge to the center; the elongated slots 6.1 are used to insert and limit the reinforcing plate 2.

[0022] Multiple side plate fixing devices 7 are provided on the surface of any turntable 6 facing the rotating shaft 5. At least one side plate fixing device 7 is located between two elongated through slots 6.1. Each side plate fixing device 7 includes a first cylinder 7.1, a quick clamp 7.2, and an L-shaped fastener 7.3. The fixed end of the first cylinder 7.1 is rotatably connected to the turntable 6, and the telescopic end of the first cylinder 7.1 is rotatably connected to the handle of the quick clamp 7.2. The clamp of the quick clamp 7.2 movably abuts against the L-shaped fastener 7.3. One side of the L-shaped fastener 7.3... One end is rotatably connected to the turntable 6, and the other end is fastened to the edge of the turntable 6; the telescopic drive of the first cylinder 7.1 drives the quick clamp 7.2 to press against and tighten the L-shaped buckle 7.3, or to release the L-shaped buckle 7.3. When the clamp of the quick clamp 7.2 presses against the L-shaped buckle 7.3, the L-shaped buckle 7.3 is fastened to the edge of the turntable 6, which can press the end of the side plate 1 onto the edge of the turntable 6, thereby temporarily limiting and fixing the side plate 1 on the turntable 6, preventing the side plate 1 from moving on the turntable 6 and causing welding misalignment.

[0023] Multiple rib fixing devices 8 are provided on the surface of any turntable 6 facing another turntable 6. There is at least one rib fixing device 8 between two elongated through grooves 6.1. The rib fixing device 8 includes a second cylinder 8.1 and a cylindrical rubber head 8.2. The fixed end of the second cylinder 8.1 is fixed on the turntable 6, and the telescopic end of the second cylinder 8.1 is fixed to the cylindrical rubber head 8.2. The cylindrical rubber head 8.2 faces the elongated through groove 6.1. The telescopic movement of the second cylinder 8.1 drives the cylindrical rubber head 8.2 to press the side end of the rib 2 against an inner side wall of the elongated through groove 6.1, thereby temporarily limiting and fixing the rib 2 on the turntable 6 and preventing the rib 2 from moving on the turntable 6 and causing misalignment with the side plate 1 during welding.

[0024] A baffle 10 is fixed to the side of the elongated through groove 6.1 of the turntable 6 on the fixed trapezoidal frame 2. The baffle 10 is positioned on the side facing the rotating shaft 5. The baffle 10 blocks the axial movement of the side plate 1 in the electrode shell and aligns with the edge of the side end of the electrode shell.

[0025] Working principle: In use, the side plate 1 is placed between two turntables 6, with the end of the side plate 1 resting on the edge of the turntable 6. The stiffening plate 2 is inserted into the long through groove 6.1. The first cylinder 7.1 of the side plate fixing device 7 extends out, driving the quick clamp 7.2 to press against and tighten the L-shaped buckle 7.3, pressing the end of the side plate 1 against the edge of the turntable 6, thus temporarily limiting the side plate 1 on the turntable 6. The second cylinder 8.1 of the stiffening plate fixing device 8 extends out, driving the cylindrical rubber head 8.2 to press the side end of the stiffening plate 2 against one inner wall of the long through groove 6.1, thus temporarily limiting the stiffening plate 2 on the turntable 6. While constructing side panel 1 and stiffening plate 2, the two turntables 6 are connected. Rotating the two turntables 6 changes their positions, making it easier to construct the next side panel 1.

[0026] After the electrode shell is made, the movable trapezoidal frame 3 is moved away from the fixed trapezoidal frame 2 so that the electrode shell can be removed from the two turntables 6.

[0027] Advantages: After the side plates and stiffeners are assembled on the turntable 6, the side plate fixing device 7 uses the telescopic drive of the first cylinder 7.1 to rotate the L-shaped clamp 7.3, so that the end of the side plate 1 is pressed against the edge of the turntable 6, achieving temporary positioning and fixing of the side plate 1 and preventing the side plate 1 from moving on the turntable 6 and causing welding misalignment. The stiffener fixing device 8 uses the telescopic drive of the second cylinder 8.1 to drive the cylindrical rubber head 8.2 to press the side end of the stiffener 2 against one of the inner walls of the long through groove 6.1, achieving temporary positioning and fixing of the stiffener 2 and preventing the stiffener 2 from moving on the turntable 6 and causing welding misalignment with the side plate 1, improving welding stability and welding quality, eliminating the need for manual support, reducing labor intensity, and ensuring accurate welding position.
