Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly to an automatic welding device for the housing of a box-type substation. Background Art

[0002] A box-type substation, also known as a prefabricated substation or a modular substation, is a highly integrated power equipment that integrates core functional modules such as high-voltage power distribution, transformers, and low-voltage power distribution in one or more sealed metal or non-metal boxes to achieve the reception, transformation, and distribution of electrical energy. It is equivalent to a small "power hub station" and is widely used in scenarios such as cities, rural areas, and industrial zones.

[0003] In a substation, its housing, as the main supporting component of the cabinet, usually uses welding to fix multiple plates to each other.

[0004] After retrieval, a welding device for a power distribution cabinet body with the publication number CN216398592U and a welding device for a power distribution cabinet body with the publication number CN118357725B are disclosed. Including but not limited to these two patents, they all clamp and fix four plates and then weld the splicing joints; For this type of welding equipment, due to the need for clamping / limiting work, the required time is relatively long, and then the welding time and clamping time are not proportional. For example, if the welding time for a frame is five minutes, then the lifting and clamping time for the plate also requires five minutes or even longer, resulting in unremarkable welding efficiency.

[0005] Secondly, this type of welding device cannot complete the welding work automatically and still requires manual assistance. As is well known, welding is a high-risk industry, with high temperatures, harmful gases, strong light radiation, etc. High temperatures may cause burns, ultraviolet rays generated by electric arcs can cause electric ophthalmia, and metal particles in the smoke and dust may cause lung diseases. Summary of the Invention

Detailed implementation manners

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0026] The following is based on Figures 1 - 18 Describe the automatic welding device for the box-type substation housing provided by the embodiments of the present invention.

[0027] Please refer to Figures 1 - 18, an embodiment of the present invention provides a technical solution: an automatic welding device for a box-type substation housing, including a box body 301 arranged in a rectangular shape. Four flat corners are provided at the four corners of the box body 301, and notches 309 are provided at all four flat corners. A welding mechanism is installed in the box body 301 and the notches 309.

[0028] Among them, the box body 301 has two Y-axis surfaces and two Z-axis surfaces. The two Y-axis surfaces are parallel to each other, and the two Z-axis surfaces are parallel to each other. The Y-axis surface is the length surface of the box body 301, and the Z-axis surface is the width surface of the box body 301. Limit plates 3 are fixed on both the Z-axis surface and the Y-axis surface of the box body 301. The limit plates 3 and the connecting parts between the limit plates 3 and the box body 301 form a supporting part. The supporting part on the Y-axis surface is lower than the supporting part on the Z-axis surface, and a receiving part is installed in the supporting part on the Y-axis surface. A lifting component is installed at the bottom of the receiving part.

[0029] Please refer to Figures 8 - 11 , the above-mentioned supporting part refers to the part between the limit plate 3 and the box body 301. This part is a plate body used to fixedly connect the limit plate 3 and the box body 301. This plate body is the supporting part. When the housing plate 4 enters between the limit plate 3 and the box body 301, when the housing plate 4 drops to the end of the stroke, it is located on the supporting part, and the housing plate 4 is supported by the supporting part. The supporting part on the above-mentioned Y-axis surface is lower than the supporting part on the Z-axis surface, that is, the supporting part on the length surface of the box body 301 is lower than the supporting part on the width surface of the box body 301. Since a receiving part and a lifting component are installed in the supporting part on the length surface of the box body 301, after the housing plate 4 in the supporting part on the length surface of the box body 301 drops to the end of the stroke, it is located on the receiving part and is supported by the receiving part, while the housing plate 4 in the supporting part on the width surface of the box body 301 directly drops to the supporting part and is supported by the supporting part on the width surface of the box body 301.

[0030] Two relatively arranged first storage boxes 2 are fixed to each other through a first connecting plate 202.

[0031] Two relatively arranged second storage boxes 201 are fixed to each other through a second connecting plate 203. The second connecting plate 203 and the first connecting plate 202 are arranged in a cross shape and fixed to each other. Plate placing mechanisms are installed on both the first storage box 2 and the second storage box 201. The first storage box 2 is fixed to the roof or the frame through a translation mechanism installed on the top.

[0032] In the embodiment of the present invention, the substation housing is essentially a framework formed by welding multiple plate bodies. Please refer to Figure 12 , this application is directed to the welding between four plate bodies to form a rectangular framework.

[0033] The basic plate bodies required for welding, that is, the housing plates 4, are respectively placed in the two first storage boxes 2 and the two second storage boxes 201.

[0034] When welding, firstly, the No. 1 storage box 2 and the No. 2 storage box 201 are driven to move to the top of the box body 301 through the translation mechanism, and the shell plates 4 in the two No. 1 storage boxes 2 and the two No. 2 storage boxes 201 are respectively placed into the supporting parts of the Y-axis surface and the Z-axis surface through the cooperation of the translation mechanism and the plate placing mechanism. The separate placement here means that they are placed into the supporting parts of the two Y-axis surfaces and the Z-axis surface in sequence. After the placement is completed, there are four shell plates 4, and they are arranged in a rectangular shape.

[0035] Among them, the shell plate 4 on the Z-axis surface is directly supported by the supporting part, while the shell plate 4 on the Y-axis surface is supported by the supporting part, so that when the four shell plates 4 fall to the end of the stroke, their bottoms are on a common plane to ensure that there will be no unevenness during welding, and the shell plate 4 can be limited by the limiting plate 3. Through the interaction of the mating surfaces of the four shell plates 4, the four shell plates 4 will not change their positions to the left and right, front and back when in the supporting part, and through the limiting of the limiting plate 3, the shell plate 4 will not be deformed to a large extent when heated during welding, which will lead to the problem of large welding welds.

[0036] When the four shell plates 4 have all completed the placement limit, the welding mechanism works, and the four shell plates 4 are welded together by the welding mechanism at the same time, so that the four shell plates 4 are fixed together.

[0037] Secondly, the welding mechanism of the present invention is an internal welding method, which allows the welding to be located on the inner wall of the frame. While having good aesthetics, it does not require grinding treatment. Because its welding part is located inside the frame and at the four corners, its burrs and irregular protrusions will not affect subsequent work.

[0038] It should also be noted that the four limiting plates 3 are each provided with an arc portion 308 on the side opposite to the box body 301, which can improve the accuracy of the placement, see Figure 8 .

[0039] The present invention performs splicing and limiting in this way, so that the butt joint positions of the four shell plates 4 are all exposed, and the welding mechanism performs welding work internally or / and externally to meet different welding requirements.

[0040] Secondly, this method is not limited to the welding of plates, but can also be used for welding square tubes, rectangular frames, etc., and has a wider range of applications.

[0041] The welding mechanism includes a stabilizing frame 303 disposed inside the box body 301 and slidably connected to the inner wall of the box body 301 . The stabilizing frame 303 is arranged in a rectangular shape, and four corners are provided with extension parts integrally formed therewith.

[0042] Among them, the extension part of the stabilizer 303 is located within the notch 309, and welding torches 307 are fixed on all four extension parts.

[0043] At least four second lead screws 306 are rotatably installed within the box body 301. Threaded transmission members 305 that are in threaded cooperation with the second lead screws 306 are sleeved on all four second lead screws 306, and the threaded transmission members 305 are fixed to the stabilizer 303.

[0044] A second motor 302 is fixed to the inner wall of the box body 301. The output shaft of the second motor 302 is connected to the four second lead screws 306 through a second drive chain 304.

[0045] In the embodiment of the present invention, when the second motor 302 operates, its output shaft synchronously drives the four second lead screws 306 to rotate through the second drive chain 304. When the second lead screws 306 rotate, the threaded transmission members 305 and the stabilizer 303 are driven to vertically rise / fall through the threaded cooperation with the threaded transmission members 305. Furthermore, the welding torches 307 are driven to rise or fall by the stabilizer 303.

[0046] Among them, when the welding torch 307 operates, welding work is performed on the housing plate 4, and the movement trajectory required for welding is achieved through vertical lifting and lowering movement.

[0047] Secondly, through the lifting method of threaded transmission, the transmission accuracy is relatively high, the movement is stable, and at the same time, the required driving force is relatively small.

[0048] It should be noted that the second motor 302 in the present invention adopts a high-precision servo motor. Of course, other types of motors can also be selected on the premise of meeting the high-precision driving requirements, such as stepper motors or DC motors, etc. The present invention does not make specific limitations.

[0049] The receiving member includes a movable slot opened on the Y-axis plane of the box body 301. A baffle 5 is horizontally slidably installed within the movable slot. An electric push rod 508 is hinged within the box body 301, and the movable rod of the electric push rod 508 is rotatably connected to the baffle 5.

[0050] Among them, a support base for slidably supporting the baffle 5 is installed within the box body 301. Limited by the wall thickness of the box body 301, in order to prevent the baffle 5 from tilting when sliding, the support base is provided. This sliding support means that when the baffle 5 slides, it is received and supported by the support base to prevent the baffle 5 from being suspended during sliding. For reference, Figure 10 、 Figure 11 , the support base is the protruding part at the bottom of the baffle 5 in the figure; Since a lifting assembly is installed in the support portion of the width surface of the box body 301, when the shell plate 4 falls to the end of the stroke, it is directly on the lifting assembly (roller 509), and there will be a height difference with the shell plate 4 on the width surface of the box body 301. Because the roller 509 is usually made of rubber material for wear resistance, the rubber itself will deform when it is stressed. Therefore, when the shell plate 4 is located on the roller 509, the roller 509 will be deformed, and then there will be a height difference when splicing. The baffle plate 5 of the present invention is located on the upper part of the roller 509, and the housing plate 4 can be supported by the baffle plate 5 to ensure that the housing plate 4 on the width surface and the length surface of the box body 301 are at the same height.

[0051] In the embodiment of the present invention, when the electric push rod 508 is working, it drives the baffle 5 to slide by extending or retracting.

[0052] The sliding movement of the baffle 5 has two effects: Effect 1: When the baffle 5 is extended, the Y-axis surface of the box body 301 is supported to ensure that the four shell plates 4 are at the same height when they are placed on the supporting part.

[0053] Effect 2: When the baffle 5 is retracted, the lifting assembly can work normally. After the shell plate 4 is welded, the shell plate 4 can be lifted by the lifting assembly, so that the shell plate 4 can be taken out more easily.

[0054] The function of the supporting portion is to effectively support the baffle 5 during the sliding process of retraction.

[0055] The lifting assembly includes a first transmission plate 501 and a second transmission plate 502 , and the first transmission plate 501 and the second transmission plate 502 are rotatably connected at the center.

[0056] Two threaded sliders 503 are slidably installed in the Y-axis support portion of the box body 301. One end of the first transmission plate 501 and the second transmission plate 502 are rotatably connected to the two threaded sliders 503, and the other end is rotatably installed with a roller 509.

[0057] A bidirectional screw rod 505 threadably matched with the two threaded sliders 503 is rotatably installed in the Y-axis support portion of the box body 301 . A transmission rod 506 is rotatably installed in the box body 301 . The transmission rod 506 is connected to the two bidirectional screw rods 505 through a bevel gear set 504 .

[0058] In an embodiment of the present invention, a driving motor is also installed in the box body 301, and the output shaft of the driving motor is connected to the transmission rod 506 through a synchronous belt or a gear, so that when the driving motor is working, the transmission rod 506 is driven to rotate through the synchronous belt, and when the transmission rod 506 rotates, the two bidirectional screw rods 505 are synchronously driven to rotate through the bevel gear set 504.

[0059] When the bidirectional lead screw 505 rotates, it drives the two threaded sliders 503 to move relatively / oppositely through the threaded engagement with the two threaded sliders 503. Then, through the first drive plate 501 and the second drive plate 502, a lifting effect is achieved. Further, after the four housing plates 4 form a frame, the first drive plate 501 and the second drive plate 502 can be used to lift it, so as to facilitate the removal after welding. The rollers 509 can reduce the friction between the first drive plate 501 and the second drive plate 502 and the housing plate 4.

[0060] By this way of lifting, the occupied space of the lifting structure is small.

[0061] The translation mechanism includes a third electric slide rail 105 fixed to the two second storage boxes 201. A second electric slide rail 103 is slidably mounted on the third electric slide rail 105. One of the first electric sliders 102 is slidably mounted on the second electric slide rail 103. A support seat 1 is fixed to the first electric slider 102.

[0062] A first electric slide rail 101 is fixed to the roof or the frame. Another first electric slider 102 is slidably mounted on the first electric slide rail 101. The first electric slider 102 is fixed to the support seat 1.

[0063] In the embodiment of the present invention, for the convenience of description, the two first electric sliders 102 are respectively named as the first block and the second block. The first block is slidably connected to the first electric slide rail 101, and the second block is slidably connected to the second electric slide rail 103.

[0064] When it is necessary to place the housing plate 4 on the supporting part of the limiting plate 3, first, through the sliding fit between the first block and the first electric slide rail 101, the support seat 1 is driven to move directly above the box body 301. Then, the first storage box 2 and the second storage box 201 move above the box body 301 following the support seat 1. Then, through the sliding of the second electric slider 104 on the third electric slide rail 105, the first storage box 2 and the second storage box 201 move along the width direction of the box body 301, and through the sliding of the second block on the second electric slide rail 103, the first storage box 2 and the second storage box 201 move in the length direction.

[0065] Among them, the above-mentioned "sliding" is all based on the electric slide rail and the electric slider.

[0066] Furthermore, it is realized that the first storage box 2 and the second storage box 201 can move onto the box body 301 or move to other positions to be misaligned with the box body 301, which is convenient for the removal of the housing plate 4 after welding.

[0067] When the first storage box 2 and the second storage box 201 move onto the box body 301, they can move forward, backward, left and right, and through the cooperation with the plate placing mechanism, the housing plate 4 is placed on the supporting part of the limiting plate 3.

[0068] As an alternative embodiment of the present invention, the same structure as described above can be used to realize the movement of the box body 301, and the effects achieved are the same as those described above, and it can be applied to scenarios where the hoisting cannot withstand frequent movements.

[0069] The plate placing mechanism includes a push plate 2010 slidably installed in the first storage box 2 and the second storage box 201, and a first lead screw 208 is rotatably installed on both sides of the first storage box 2 and the second storage box 201. A threaded sleeve 207 that is threadedly engaged therewith is sleeved on the first lead screw 208, and the threaded sleeve 207 is fixed to the push plate 2010.

[0070] First motors 205 are fixed on both sides of the first storage box 2 and the second storage box 201, and the output shaft of the first motor 205 is connected to the first lead screw 208 through a first transmission chain 206.

[0071] Lower plate openings 209 are provided at the bottom of the opposite sides of the two first storage boxes 2 and the opposite sides of the two second storage boxes 201, and upper plate openings 204 are provided at the top of the opposite sides of the two first storage boxes 2 and the opposite sides of the two second storage boxes 201.

[0072] Among them, embedding grooves 2011 are provided on the inner walls of the opposite sides of the two first storage boxes 2 and the opposite sides of the two second storage boxes 201.

[0073] In the embodiment of the present invention, when the first motor 205 operates, its output shaft drives the first lead screw 208 to rotate through the first transmission chain 206. When the first lead screw 208 rotates, the threaded sleeve 207 is driven to move axially along the first lead screw 208 through the threaded engagement with the threaded sleeve 207, and then the push plate 2010 is driven by the threaded sleeve 207 to move towards the lower plate opening 209 or the embedding groove 2011.

[0074] When the push plate 2010 moves towards the lower plate opening 209, the housing plate 4 in the first storage box 2 or the second storage box 201 is pushed towards the lower plate opening 209. When the push plate 2010 moves to the end of the stroke, due to the extrusion of the push plate 2010 on the housing plate 4 and the frictional force between multiple housing plates 4, one housing plate 4 on the lower plate opening 209 will not fall off. After the first storage box 2 or the second storage box 201 moves to the designated position, the push plate 2010 moves back and forth, so that the extrusion force on the housing plate 4 disappears, and then it falls through the lower plate opening 209 and then falls into the supporting part of the limiting plate 3. For its blanking trajectory, please refer to Figure 13 .

[0075] Among them, when adding the housing plate 4 to the first storage box 2 or the second storage box 201, the push plate 2010 is driven to move into the embedding groove 2011, and then the housing plate 4 is put into the second storage box 201 or the first storage box 2 through the plate adding port 204. Then, the put housing plate 4 is pushed away from the embedding groove 2011 by the push plate 2010. By the method of pushing once for each put housing plate 4, the housing plates 4 put into the first storage box 2 or the second storage box 201 can be stacked in sequence.

[0076] Through the above description, the plate lowering process can take into account the stacking during feeding and the material control during discharging, and has a very simple structure and high practicability.

[0077] The width of the plate lowering port 209 is greater than that of a single housing plate 4 and less than that of two housing plates 4.

[0078] In the embodiment of the present invention, when the extrusion force applied to the stacked housing plates 4 disappears, only a single housing plate 4 can be put through the plate lowering port 209.

[0079] Among them, arc-shaped portions 308 are provided on opposite sides of the limiting plate 3 and the box body 301, and the accuracy during putting can be improved through the arc-shaped portions 308.

[0080] A control device 507 is fixed to the box body 301, and the electric push rod 508, the second motor 302, and the first motor 205 are all electrically connected to the control device 507 through wires.

[0081] In the embodiment of the present invention, the electronic components or the components that need to be driven involved in the present invention are all electrically connected to the control device 507, including but not limited to the electric push rod 508, the second motor 302, and the first motor 205.

[0082] As Figures 14 - 18 shown, as an optional embodiment of the present invention: a sleeve plate 3002 is slidably mounted on the support, and a sliding plate 3003 is slidably mounted in the sleeve plate 3002, and a cooperating connecting member is installed between the sleeve plate 3002 and the sliding plate 3003.

[0083] The sliding plate 3003 is rotatably connected to the electric push rod 508; A driving rack plate 30 is fixed to one side of the sliding plate 3003, and the driving rack plate 30 cooperates with a driven gear 3001 rotatably mounted in the box body 301. A transmission column 3007 is also rotatably mounted in the box body 301. The transmission column 3007 is connected to the transmission rod 506 through one of the second bevel gear sets 3008, and the transmission column 3007 is also connected to the rotating shaft of the driven gear 3001 through a third bevel gear set 3009.

[0084] The bracket is provided with a stroke limiting groove 3011, and a stroke limiting block 3012 fixedly connected to the sleeve plate 3002 is slidably installed in the stroke limiting groove 3011.

[0085] In the embodiment of the present invention, when the electric push rod 508 works, the movable rod of the electric push rod 508 is retracted to drive the sliding plate 3003 to slide on the bracket. When the sliding plate 3003 moves, the sleeve plate 3002 is driven to move synchronously through the connecting member. At the same time, the stroke limiting block 3012 moves with the sleeve plate 3002. When the stroke limiting block 3012 moves to the end of the stroke, the stroke limiting block 3012 is limited by the stroke limiting groove 3011, so that the sleeve plate 3002 stops moving and the connecting member loses its cooperation.

[0086] After the sleeve plate 3002 and the stroke limiting block 3012 stop moving, the sliding plate 3003 continues to move to drive the driven gear 3001 to rotate through the driving rack plate 30. When the driven gear 3001 rotates, the transmission column 3007 is driven to rotate through the third bevel gear set 3009, and then the transmission rod 506 is driven to rotate through the second bevel gear set 3008. When the transmission rod 506 rotates, the lifting assembly works accordingly.

[0087] So that when the sliding plate 3003 moves, the sleeve plate 3002 can be driven to retract and release the support through the connecting member, and at the same time, the sliding plate 3003 can continue to move after the sleeve plate 3002 is retracted, and the subsequent continuous movement can drive the work of the lifting assembly.

[0088] When the electric push rod 508 works and its movable rod pushes the sliding plate 3003 to move, it will push the sleeve plate 3002 to move, and at the same time, the connecting member is cooperated again.

[0089] It should be noted that the third bevel gear set 3009 includes two meshing bevel gears, one is fixedly coaxially connected with the transmission column 3007, and the other is fixedly coaxially connected with the driven gear 3001. The second bevel gear set 3008 also includes two meshing bevel gears, and the two bevel gears are respectively fixedly coaxially connected with the transmission column 3007 and the transmission rod 506.

[0090] The connecting member includes a plurality of live holes 3005 equidistantly opened on the sliding plate 3003. A top smooth shaft 3004 is slidably installed in each of the plurality of live holes 3005. A spring 3006 is fixed to the end of the top smooth shaft 3004, and the other end of the spring 3006 is fixed to the bottom of the live hole 3005.

[0091] A plurality of arc grooves 3013 cooperating with the top smooth shaft 3004 are equidistantly opened on the inner wall of the sleeve plate 3002.

[0092] In the embodiment of the present invention, initially, the top smooth shaft 3004 is located within the arc groove 3013. When the sliding plate 3003 moves, the cooperation between the top smooth shaft 3004 and the arc groove 3013 drives the sleeve plate 3002 to move accordingly. When the sleeve plate 3002 moves, it drives the stroke limit block 3012 to move. When the stroke limit block 3012 moves to the end of the stroke in the stroke limit groove 3011, due to the limitation of the stroke limit block 3012, when the sliding plate 3003 continues to move, the spring 3006 is compressed through the cooperation between the top smooth shaft 3004 and the arc groove 3013, causing the top smooth shaft 3004 to retract into the live hole 3005, and further enabling the sliding plate 3003 to continue moving. At this time, this movement does not drive the sleeve plate 3002 to move.

[0093] When the sliding plate 3003 moves back, the top smooth shaft 3004 will coincide with the arc groove 3013 again, thereby releasing the elastic potential energy when the spring 3006 is compressed, causing the top smooth shaft 3004 to be within the arc groove 3013 again. When the sliding plate 3003 retracts again next time, the sleeve plate 3002 can be driven to move accordingly through the cooperation between the retracted top smooth shaft 3004 and the arc groove 3013.

[0094] Among them, the function of this embodiment is that after the sleeve plate 3002 is retracted, the sliding plate 3003 can move, thereby driving the lifting assembly to work.

[0095] It should be noted that this embodiment is an optimized improvement of the above embodiment. The sleeve plate 3002 in this embodiment is used to equivalently replace the baffle 5 in the above embodiment.

[0096] When the present invention is in use (during operation), with the assistance of the pushing assembly, the housing plate 4 is added to the first storage box 2 and the second storage box 201 and stacked in sequence.

[0097] Through the cooperation of the translation mechanism and the feeding assembly, the housing plates 4 stored in the first storage box 2 and the second storage box 201 are sequentially fed to the designated positions, enabling the placed housing plates 4 to be spliced and limitedly fixed.

[0098] Then, the four housing plates 4 are welded and fixed through the welding assembly.

[0099] Finally, the frame formed by welding the four housing plates 4 is pushed out through the lifting assembly. Finally, the frame is taken out by the grasping device.

[0100] Automated welding can be achieved by repeating the above description.
