Description

Technical Field

[0001] The invention relates to the technical field of transformer oil tanks, and in particular to a transformer oil tank welding flipping device. Background Art

[0002] The transformer oil tank is an important component of the transformer. As the outer shell of the transformer, it not only protects the internal core and winding from direct influence of the external environment, but also undertakes the important responsibilities of insulation and heat dissipation.

[0003] Round oil tanks are usually used in outdoor transformers because this structure is more resistant to external attacks and corrosion; round oil tanks have the characteristics of fewer gaps, good rigidity, strong sealing, etc., and are small in size, light in weight, and easy to transport and install.

[0004] The importance of transformer oil tank welding lies in the fact that the oil tank needs to withstand a certain pressure and meet strict sealing requirements; high-quality welding can ensure the sealing, strength and durability of the oil tank, thereby ensuring the safe and reliable operation of the transformer.

[0005] In most of the current welding processes of circular transformer oil tanks, the welding slag produced during welding is usually removed after natural cooling and solidification. Usually, the natural cooling time is relatively long, and the circular transformer oil tank can only proceed to subsequent processes after the welding slag is removed. The process of removing the welding slag after natural cooling is relatively time-consuming, which leads to a relatively long production process of the circular transformer oil tank, thereby reducing work efficiency.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figure 1 and Figure 2As shown, a transformer oil tank welding flipping device comprises a rectangular frame 1, wherein the front and rear sides of the inner surface of the rectangular frame 1 are provided with mutually interpenetrating rectangular grooves 2, the upper parts of the front and rear sides of the inner surface of the rectangular frame 1 are slidably connected with a slide plate 5, an electric telescopic rod 4 is fixedly connected to the middle part of the left side of the inner surface of the rectangular groove 2, a connecting plate 7 is fixedly connected to the right end of the piston rod at the output end of the electric telescopic rod 4, an electromagnet 2 6 is fixedly connected to the upper end of the connecting plate 7, an electromagnet 1 3 is fixedly connected to the upper end of the horizontal part of the slide plate 5, a supporting assembly 8 is arranged on the right side of the slide plate 5, an L-shaped plate 11 is fixedly connected to the right part of the upper end of the rectangular frame 1, a rotating assembly 9 is arranged at the rear right part of the L-shaped plate 11, and a slag cleaning assembly 10 is arranged at the front right part of the L-shaped plate 11.

It generates wind force mechanically to accelerate the air flow, thereby achieving the purpose of cooling. It is a mature technical means in the prior art. This scheme only borrows its function of rapid cooling, and it is not shown here. At the same time, its structure and working principle are not further elaborated.

[0031] In the specific implementation, the components of the circular transformer oil tank welding are divided into a cylindrical component and a circular cover component. The cylindrical component is supported by the support component 8, and the circular cover component is installed on the rotating component 9. The electromagnet 2 6 is energized so that the connecting plate 7 adsorbs the slide plate 5, and the electric telescopic rod 4 is turned on to extend the piston rod, driving the support component 8 and the cylindrical component to move to a position close to the circular cover part, and the piston rod is further extended so that the rear end of the circular cover component contacts the slag cleaning component 10. At this time, the electromagnet 2 6 is de-energized so that the connecting plate 7 no longer adsorbs the slide plate 5, and the electromagnet 1 3 is energized so that the slide plate 5 is adsorbed with the rectangular frame 1 and stabilized at the above position. At this time, the staff starts to weld the circular cover component and the cylindrical component together. During the welding process, the cooling fan is turned on to accelerate the solidification of the welding slag.

[0032] After a part of the round cover part and the cylindrical part are welded, the electric telescopic rod 4 is turned on to extend the piston rod to operate the rotating component 9 and the slag cleaning component 10. The slag cleaning component 10 is operated to clean the welding slag, and the rotating component 9 drives the cylindrical part and the round cover part to rotate, so that the unwelded part rotates in front of the staff, and the staff starts the subsequent welding work.

[0033] Specifically, in order to facilitate the work of welding the round transformer tank, refer to Figure 3The support assembly 8 includes a round rod 81, which is rotatably connected to the upper right end of the vertical part of the slide plate 5, a rectangular plate 82 is fixedly connected to the right end of the round rod 81, a sliding rod 84 is fixedly connected to the middle of the right end of the rectangular plate 82, and a hydraulic cylinder 83 is fixedly connected to the upper and lower parts of the right end of the rectangular plate 82. A fixed circular plate 1 85 is slidably connected to the left side of the outer surface of the sliding rod 84, and the right ends of the piston rods at the output ends of the two hydraulic cylinders 83 are fixedly connected to the left ends of the fixed circular plate 1 85. A fixed circular plate 2 86 is fixedly connected to the right side of the outer surface of the sliding rod 84, and three connecting rod assemblies 87 are arranged in an arc array on the outer surfaces of the fixed circular plates 1 85 and 86;

[0034] Further reading Figure 4 The connecting rod assembly 87 includes two connecting members 871 and a supporting member 873. The two connecting members 871 are fixedly connected to the outer surfaces of the fixed circular plate 1 85 and the fixed circular plate 2 86 respectively. The outer surfaces of the two connecting members 871 are rotatably connected to connecting rods 872. The two connecting rods 872 are rotatably connected to the supporting member 873. The outer surface of the supporting member 873 is fixedly connected to an arc-shaped rubber block 874.

[0035] Further reading Figure 5 , the rotating assembly 9 includes a driving assembly 91, and a driven assembly 92 is arranged on the front side of the driving assembly 91; the driving assembly 91 includes a rack 911, and the rack 911 is fixedly connected to the rear end of the connecting plate 7, and a rotating rod 913 is rotatably connected to the right part of the lower side of the inner surface of the rectangular groove 2, and the upper end of the rotating rod 913 passes through the upper right part of the inner surface of the rectangular groove 2 and the rear end of the upper end of the horizontal part of the L-shaped plate 11 and extends to the upper side of the horizontal part of the L-shaped plate 11, and a gear 912 is fixedly connected to the lower side of the outer surface of the rotating rod 913, and the gear 912 is meshed with the rack 911; the driven assembly 92 includes a pulley 921 and a telescopic rod 925, and the pulley 921 on the rear side is connected to the outer surface of the rotating rod 913 The upper side is fixedly connected, the middle part of the upper end of the horizontal part of the L-shaped plate 11 is rotatably connected with a rotating rod 2 922, the pulley 1 921 on the front side is fixedly connected to the lower side of the outer surface of the rotating rod 2 922, and the upper side of the outer surface of the rotating rod 2 922 is fixedly connected with a bevel gear 1 923, the middle part of the right end of the L-shaped plate 11 penetrates and extends to the left side of the L-shaped plate 11 and is rotatably connected with a rotating rod 3 928, the right side of the outer surface of the rotating rod 3 928 is fixedly connected with a bevel gear 2 924, the bevel gear 2 924 is meshed with the bevel gear 1 923, the left end of the rotating rod 3 928 is fixedly connected with a spring 926, the left and right ends of the telescopic rod 925 are respectively fixedly connected to the right and left sides of the inner surface of the spring 926, and a positioning component 927 is provided on the left side of the spring 926;

[0036] Further reading Figure 6 The positioning assembly 927 includes a fixed cylinder 9271, which is fixedly connected to the left end of the spring 926. An elastic material 9272 is fixedly connected to the right side of the inner surface of the fixed cylinder 9271. A positioning disk 9273 is slidably connected to the inner surface of the fixed cylinder 9271. The upper and lower parts of the left end of the positioning disk 9273 are provided with through ventilation grooves 9274. The inner surfaces of the two ventilation grooves 9274 are fixedly connected to electromagnets 9275.

[0037] The upper ends of the three arc-shaped rubber blocks 874 are all arc-shaped and convex;

[0038] The elastic material 9272 mentioned above is a thermoplastic elastomer, which has good toughness and resilience and can quickly return to its original shape after being stressed. It is a mature technical means in the prior art, and this solution will not further elaborate on its structure and working principle;

[0039] In a specific implementation, the two hydraulic cylinders 83 are turned on to retract the piston rods, thereby driving the fixed circular plate 85 to slide toward the rectangular plate 82, so that the six connecting rods 872 are rotated, and the three connecting rod assemblies 87 are retracted until the support assembly 8 is adjusted to a state smaller than the inner diameter of the cylindrical component to be welded;

[0040] With the help of the auxiliary machinery, the cylindrical component is lifted to a position facing the support assembly 8, and the electromagnet 2 6 is energized so that the connecting plate 7 adsorbs the slide plate 5, and the electric telescopic rod 4 is turned on to extend the piston rod, thereby driving the support assembly 8 to move into the cylindrical component, and then the two hydraulic cylinders 83 are turned on to extend and retract the piston rods, thereby driving the fixed circular plate 1 85 to slide toward the fixed circular plate 2 86, so that the six connecting rods 872 are all rotated, thereby driving the three support members 873 to prop up and support the inner surface of the cylindrical component, so that the support assembly 8 supports and stably lifts the cylindrical component, and the upper ends of the three arc-shaped rubber blocks 874 are all arc-shaped convex, which increases the friction force while allowing the three arc-shaped rubber blocks 874 to better fit with the inner surface of the cylindrical component, so that the stability of the support assembly 8 supporting the cylindrical component is stronger;

[0041] Power on both electromagnets 9275, and place the round cover component close to the positioning disc 9273. At this time, the round cover component is adsorbed on the positioning disc 9273 through the two electromagnets 9275. Press the round cover component. If the round cover component is not blocked at this time, it is directly pressed into the fixed cylinder 9271, which means that the installation position of the round cover component is facing the installed cylinder component. After no more pressing, the round cover component is rebounded to the outside of the fixed cylinder 9271 under the action of the elastic material 9272. This operation is convenient and can quickly complete the installation of the round cover component in the position facing the cylinder component, thereby saving time and providing convenience for the welding work of the staff.

[0042] After completing the above operations, turn on the electric telescopic rod 4 to extend the piston rod, so that the support assembly 8 and the cylindrical component move to a position close to the circular cover component, and then continue to extend the piston rod, so that the circular cover component moves to a position where the right end is close to the slag cleaning component 10. The telescopic rod 925 allows the positioning component 927 to have space to move. At this time, the spring 926 is in a compressed state. When the positioning component 927 is no longer in a compressed state, the spring 926 can help the positioning component 927 to return to its original position. Then, the electromagnet 2 6 is powered off, and the electromagnet 1 3 is powered on, so that the slide plate 5 is adsorbed together with the rectangular frame 1, so that the cylindrical component maintains the above-mentioned middle position and will not be displaced in the subsequent welding work, thereby affecting the normal progress of the welding work;

[0043] The staff began to weld the round cover component and the cylindrical component together. While the welding work was in progress, the cooling fan was turned on to accelerate the solidification of the welding slag produced by welding. When a part of the welding was completed, the electric telescopic rod 4 was turned on to continuously extend the piston rod, driving the rack 911 to move, thereby driving the gear 912 to rotate. The rotation of the gear 912 drove the rotating rod 913 to rotate. Under the action of the pulley 921, the rotating rod 922 was rotated, thereby driving the bevel gear 923 to rotate. Since the bevel gear 923 and the bevel gear 924 were meshed, the rotation of the bevel gear 923 drove the bevel gear 924 to rotate, thereby driving the rotating rod 3 928 to rotate, thereby driving the positioning assembly 927 to rotate, so that the round cover component and the cylindrical component were rotated, and the unwelded position was rotated in front of the staff. In this way, the staff does not need to keep changing position during the welding process to find the unwelded position for welding. The rotation can also rotate the position that the staff cannot touch during welding, thereby providing convenience for the welding work of the staff.

[0044] Specifically, in order to remove welding slag while welding the transformer tank, thereby saving time and improving work efficiency, refer to Figure 7, the slag cleaning component 10 includes a rack 2 101, the rack 2 101 is fixedly connected to the front end of the connecting plate 7, the right part of the lower side of the inner surface of the rectangular groove 2 is rotatably connected to a rotating rod 4 103, the upper end of the rotating rod 4 103 passes through the right part of the upper side of the inner surface of the rectangular groove 2 and the front part of the upper end of the horizontal part of the L-shaped plate 11 and extends to the upper side of the horizontal part of the L-shaped plate 11, the lower side of the outer surface of the rotating rod 4 103 is fixedly connected to a gear 2 102, the gear 2 102 is meshed with the rack 2 101, and a cleaning component 104 is arranged on the upper side of the rotating rod 4 103; the cleaning component 104 includes a bevel gear 3 1041, the bevel gear 3 1041 and The upper side of the outer surface of the rotating rod four 103 is fixedly connected, the upper right end of the vertical part of the L-shaped plate 11 is rotatably connected to the rotating rod five 1043, the right side of the outer surface of the rotating rod five 1043 is fixedly connected to the bevel gear four 1042, the bevel gear four 1042 is meshed with the bevel gear three 1041, the outer surface of the rotating rod five 1043 is fixedly connected to the pulley two 1044, the middle part of the upper right end of the L-shaped plate 11 penetrates and extends to the left side of the L-shaped plate 11 and is rotatably connected to the rotating rod six 1045, the upper pulley two 1044 and the outer surface of the rotating rod six 1045 are fixedly connected, and the left end of the rotating rod six 1045 is fixedly connected to the wire brush 1046.

[0045] In the specific implementation, according to the above operation, at this time, the welding part at the right end of the round cover part is in a state of being close to the wire brush 1046, and the worker welds the position of the round cover part in front of him that is not in contact with the wire brush 1046 during the welding process;

[0046] When the electric telescopic rod 4 is continuously extended, the piston rod drives the rack 1 911 to move, and drives the rack 2 101 to move, thereby driving the gear 2 102 to rotate, thereby driving the rotating rod 4 103 to rotate, so that the bevel gear 3 1041 rotates. Since the bevel gear 3 1041 and the bevel gear 4 1042 are meshed, the rotation of the bevel gear 3 1041 drives the bevel gear 4 1042 to rotate, so that the rotating rod 5 1043 rotates, and under the action of the pulley 2 1044, the rotating rod 6 1045 rotates, so that the wire brush 1046 rotates to clean the welding slag;

[0047] In this way, while the rotating component 9 drives the round cover part and the cylindrical part to rotate, the wire brush 1046 rotates, and the rotation direction is opposite to that of the round cover part and the cylindrical part. In this way, the welding slag generated can be processed while welding, and there is no need to process the welding slag separately after welding, thereby saving working time and improving work efficiency.

[0048] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic rod 4 and the two hydraulic cylinders 83 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0049] The working principle of the present invention is:

[0050] The cylindrical component is supported and lifted by the support assembly 8, and the round cover component is installed at a position facing the cylindrical component by the positioning assembly 927;

[0051] Power on the electromagnet 2 6, turn on the electric telescopic rod 4 to extend the piston rod, drive the cylindrical part to move to a position close to the round cover part, continue to extend the piston rod, so that the round cover part and the cylindrical part move to a position where the right end of the round cover part is close to the wire brush 1046, turn off the power of the electromagnet 2 6, and power on the electromagnet 1 3;

[0052] Then the staff starts the welding work, and turns on the cooling fan while welding. After completing a part of the welding, the electric telescopic rod 4 is turned on to continuously extend the piston rod, so that the rotating component 9 drives the round cover part and the cylinder part to rotate, and the unwelded position is rotated in front of the staff. At the same time, the wire brush 1046 rotates to process the welding slag.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
