Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinet assembly technology, specifically relating to assembly equipment used in the manufacture of ring main units. Background Technology

[0002] A distribution cabinet is a cabinet that integrates electrical components for power distribution. It is primarily used to receive, distribute, and control electrical energy, and to provide power-off protection in case of overload, short circuit, or leakage, ensuring the safe and stable operation of the power system. Assembling a distribution cabinet requires first splicing the various outer shells together, and then fixing them in place using screws or welding.

[0003] A ring main unit (RMU) is a combination of high-voltage switchgear, typically installed in a metal or non-metal insulated cabinet to form a ring network power supply unit. Its core function is to distribute, control, and protect electrical energy. RMUs are also a type of distribution cabinet, and in actual production, they can be manufactured through assembly.

[0004] A patent with publication number CN222851903U discloses a power distribution cabinet assembly device. This device includes an assembly platform, electromagnets, a drive motor, adjusting columns, sliding tracks, uprights, and crossbars. During assembly, the electromagnets fix the top, bottom, left, and right outer shells of the power distribution cabinet. The rear outer shell of the cabinet is placed on the assembly platform. Then, the drive motor is activated, causing the adjusting columns to slide within the sliding tracks, thereby adjusting the positions of the uprights and crossbars. This, in turn, moves the top, bottom, left, and right outer shells of the power distribution cabinet towards the edge of the rear outer shell for assembly. After assembly, the seams can be welded and fixed, thus assembling the power distribution cabinet.

[0005] However, in the above-mentioned scheme, the electromagnets are all located on the inside of the horizontal bars. This means that when operators need to fix the top, bottom, left, and right outer shells of the distribution cabinet, they must first move the outer shells around the horizontal bars and vertical bars to the inside of the horizontal bars and vertical bars before they can be fixed. The spatial environment inside the horizontal bars and vertical bars is quite restrictive, making it inconvenient to fix the top, bottom, left, and right outer shells of the distribution cabinet in the corresponding positions. Therefore, the actual use effect is generally poor. Summary of the Invention

[0012] Furthermore, the first auxiliary component includes a first gear, and the first gear is fixedly sleeved on the outer surface of the first rotating seat; a first rack is fixedly arranged on the inner wall of the first slide groove, and the first gear and the first rack engage in contact-type transmission.

[0013] Furthermore, the second limiting member includes a second rotating seat, which is rotatably mounted on the top of the second slider; the second slider is provided with a second spring positioning pin, and the second rotating seat is provided with a positioning hole that engages with the second spring positioning pin; the second telescopic member includes a second electric push rod, which is fixedly mounted on the top of the second rotating seat, and the telescopic shaft of the second electric push rod is fixedly connected to the second adsorption frame.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-8 As shown, the technical solution adopted by the present invention is as follows: An assembly device for manufacturing ring main units includes an assembly platform 1. A limiting plate 33 is fixedly installed on the top of the assembly platform 1. Two first sliders 15 and two second sliders 23 are both slidably limited on the top of the assembly platform 1. The two first sliders 15 slide towards or away from each other, and the two second sliders 23 slide towards or away from each other. A driving mechanism acting on the two first sliders 15 is provided inside the assembly platform 1. The first sliders 15 are driven by the two second sliders 23 through a transmission component.

[0023] Furthermore, the top of the assembly platform 1 is provided with a first groove 11 that is limited and slidably engaged with the first slider 15, and a second groove 12 that is limited and slidably engaged with the second slider 23.

[0024] The drive mechanism includes a second motor 10, which is fixedly mounted on the outer surface of the assembly table 1. The output shaft of the second motor 10 is fixedly provided with a second lead screw 21. The second lead screw 21 is a bidirectional lead screw, and the two first sliders 15 are threadedly engaged with the two threaded sections of the second lead screw 21.

[0025] In addition, a guide rod 22 is fixedly installed inside the second slide groove 12, and the second slider 23 is slidably sleeved on the outer surface of the guide rod 22; a spring 36 is sleeved on the outer surface of the guide rod 22, one end of the spring 36 is fixedly connected to the second slider 23, and the other end is fixedly connected to the assembly table 1.

[0026] Among them, such as Figures 7-8 As shown, the transmission component includes an inclined plate 34. The assembly platform 1 has a clearance groove 16 connected to the first slide groove 11 and the second slide groove 12. An inclined plate 34 is fixedly mounted on both sides of one of the first sliders 15, and both inclined plates 34 are slidably positioned within the clearance groove 16. Each inclined plate 34 has a horizontal surface 341 and an inclined surface 342. Each second slider 23 has an inclined groove 35 at its bottom. The second sliders 23 correspond one-to-one with the inclined plates 34, and each inclined groove 35 engages with the corresponding inclined surface 342 in a transmission cooperation.

[0027] The second motor 10 is started, and its output shaft drives the second lead screw 21 to rotate, causing the two first sliders 15 to move closer together. During the sliding of one of the first sliders 15, the two inclined plates 34 slide synchronously. As the inclined plate 34 slides, the inclined surface 342 engages with the inclined groove 35, thereby causing the two second sliders 23 to move closer together and compressing the spring 36. When the inclined surface 342 disengages from the inclined groove 35, the horizontal surface 341 of the inclined plate 34 slides against the second slider 23. Afterward, as the two first sliders 15 move closer together, the two second sliders 23 no longer move closer together.

[0028] Each first slider 15 has a first adsorption frame 27 rotatably mounted on its top. Each of the two first adsorption frames 27 has a second electromagnet 28 on its opposite side. A first limiting member and a first telescopic member are provided between the first slider 15 and the first adsorption frame 27. Each second slider 23 has a second adsorption frame 31 rotatably mounted on its top. Each of the two second adsorption frames 31 has a third electromagnet 32 ​​on its opposite side. A second limiting member and a second telescopic member are provided between the second slider 23 and the second adsorption frame 31.

[0029] Furthermore, a second protective pad 29 is provided on the opposite sides of the two first adsorption racks 27 and the opposite sides of the two second adsorption racks 31.

[0030] In addition, the first slider 15 is driven to engage with the first adsorption frame 27 through the first auxiliary component, and the second slider 23 is driven to engage with the second adsorption frame 31 through the second auxiliary component.

[0031] The first limiting component includes a first rotating seat 17, and the first rotating seat 17 is rotatably mounted on the top of the first slider 15; the first slider 15 is provided with a first spring positioning pin 19, and the first rotating seat 17 is provided with a positioning hole that engages with the first spring positioning pin 19.

[0032] The first telescopic component includes a first electric push rod 18, which is fixedly mounted on the top of the first rotating seat 17. The telescopic shaft of the first electric push rod 18 is fixedly connected to the first suction frame 27. The height of the first suction frame 27 can be adjusted by the first electric push rod 18 to suit more situations.

[0033] The first auxiliary component includes a first gear 20, which is fixedly sleeved on the outer surface of the first rotating seat 17; a first rack 13 is fixedly installed on the inner wall of the first slide groove 11, and the first gear 20 and the first rack 13 engage in contact-type transmission.

[0034] The second limiting component includes a second rotating seat 24, which is rotatably mounted on the top of the second slider 23; a second spring positioning pin 30 is provided inside the second slider 23, and a positioning hole is provided on the second rotating seat 24 to engage with the second spring positioning pin 30.

[0035] The second telescopic component includes a second electric push rod 25, which is fixedly mounted on the top of the second rotating seat 24. The telescopic shaft of the second electric push rod 25 is fixedly connected to the second adsorption frame 31. The height of the second adsorption frame 31 can be adjusted via the second electric push rod 25 to suit more situations.

[0036] The second auxiliary component includes a second gear 26, which is fixedly sleeved on the outer surface of the second rotating seat 24; a second rack 14 is fixedly installed on the inner wall of the second slide groove 12, and the second gear 26 and the second rack 14 engage in contact-type transmission.

[0037] In addition, a top plate 4 is provided above the assembly platform 1. Three fixed columns 2 are fixedly installed vertically between the top plate 4 and the assembly platform 1, and a first lead screw 3 is rotatably installed vertically. The three fixed columns 2 and the first lead screw 3 are located at the four corners of the assembly platform 1. A first motor 5 is fixedly embedded in the top plate 4, and the output shaft of the first motor 5 is coaxially and fixedly connected to the top of the first lead screw 3.

[0038] Furthermore, an adsorption mechanism is vertically limited and slidably installed between the assembly platform 1 and the top plate 4. A connecting frame 6 is fixedly installed on the top of the adsorption mechanism. The connecting frame 6 is slidably connected to the fixed column 2 and threadedly connected to the first lead screw 3.

[0039] Among them, such as Figure 5 As shown, the adsorption mechanism includes an adsorption plate 7, the bottom of the connecting frame 6 is fixedly provided with the adsorption plate 7, a number of first electromagnets 9 are fixedly embedded in the adsorption plate 7, and the bottom of the adsorption plate 7 is fixedly provided with a first protective pad 8.

[0040] Working principle: In use, the rear outer shell of the cabinet is placed between the four limiting plates 33. The first motor 5 is started, and the output shaft of the first motor 5 drives the first lead screw 3 to rotate. With the guidance of the fixed column 2, the connecting frame 6 drives the adsorption plate 7 to descend until the first protective pad 8 at the bottom of the adsorption plate 7 contacts the rear outer shell of the cabinet. At this time, the first electromagnet 9 is energized, and the adsorption plate 7 adsorbs the rear outer shell of the cabinet. Immediately afterwards, the output shaft of the first motor 5 is reversed, and the adsorption plate 7 drives the rear outer shell of the cabinet to rise. After rising to a suitable distance, the first motor 5 is turned off.

[0041] Then, the second electromagnet 28 and the third electromagnet 32 ​​are energized, so that the top and bottom shells of the cabinet are respectively attached to the two first suction brackets 27, and the shells of the left and right side walls of the cabinet are respectively attached to the two second suction brackets 31.

[0042] Because the second protective pad 29 is located on the outside of the two first suction cups 27 and the two second suction cups 31, the operator can directly fix the cabinet shell in the corresponding position. The first protective pad 8 and the second protective pad 29 prevent the cabinet shell from being bumped or knocked. Furthermore, the first electric push rod 18 and the second electric push rod 25 allow the height of the first suction cup 27 and the second suction cup 31 to be adjusted to accommodate shells of different heights.

[0043] Then, the second motor 10 is started, and the output shaft of the second motor 10 drives the second lead screw 21 to rotate, causing the two first sliders 15 to move closer to each other. This, in turn, causes the top and bottom outer shells of the cabinet to move closer together via the first suction frame 27. During this process, the first gear 20 meshes with the first rack 13, causing the first rotating seat 17 to drive the first suction frame 27 and the outer shells adsorbed by the first suction frame 27 to rotate against the elastic force of the first spring positioning pin 19.

[0044] After the first gear 20 disengages from the first rack 13, the first spring positioning pin 19 repositions the first rotating seat 17. At this time, the first rotating seat 17 drives the first suction frame 27 and the top and bottom outer shells of the cabinet to rotate 180 degrees, causing the top and bottom outer shells of the cabinet to rotate inward.

[0045] In addition, during the sliding of one of the first sliders 15, the two inclined plates 34 will slide synchronously. During the sliding of the inclined plate 34, the inclined surface 342 will engage with the inclined groove 35, thereby driving the two second sliders 23 to move closer to each other and compress the spring 36 as the two first sliders 15 approach each other.

[0046] When the two second sliders 23 approach each other, the two outer shells of the cabinet will approach each other through the second adsorption frame 31. During this process, with the help of the meshing of the second gear 26 and the second rack 14, the two second rotating seats 24 drive the second adsorption frame 31 and the outer shell adsorbed by the second adsorption frame 31 to rotate against the elastic force of the second spring positioning pin 30.

[0047] After the second gear 26 disengages from the second rack 14, the second spring positioning pin 30 repositions the second rotating seat 24. At this time, the second rotating seat 24 drives the second adsorption frame 31 and the left and right outer shells of the cabinet to rotate 180 degrees, causing the left and right outer shells of the cabinet to rotate inward.

[0048] Furthermore, as the inclined panel 34 continues to slide, the inclined surface 342 gradually disengages from the inclined groove 35. Once the inclined surface 342 disengages from the inclined groove 35, the horizontal surface 341 of the inclined panel 34 will slide against the second slider 23 under the elastic action of the spring 36. Subsequently, as the two first sliders 15 move closer to each other, the two second sliders 23 no longer move closer to each other, causing the top and bottom outer shells of the cabinet to continue moving closer to each other, while the left and right outer shells of the cabinet no longer move closer.

[0049] After the top and bottom shells of the cabinet continue to approach each other for a certain distance, the top and bottom shells of the cabinet will abut against the left and right shells of the cabinet, generating a certain amount of clamping force.

[0050] Since both the first adsorption bracket 27 and the second adsorption bracket 31 have rotated 180 degrees, the clamping force between the outer shells will act on the corresponding first adsorption bracket 27 and second adsorption bracket 31, without affecting the adsorption effect between the second electromagnet 28, the third electromagnet 32 ​​and the corresponding outer shell. Simultaneously, under the action of the first spring positioning pin 19 and the second spring positioning pin 30, the outer shells will not rotate relative to each other, ensuring a tight fit between the outer shells and thus improving the subsequent welding quality.

[0051] Next, the first motor 5 is started, and its output shaft drives the rear outer shell of the cabinet to descend, moving it to the top of the shell composed of the top, bottom, and left / right side shells. Welding can then be performed. (Because the rear outer shell is far from the assembly table 1, the first electric push rod 18 and the second electric push rod 25 are avoided from interfering with the subsequent welding of the rear outer shell, making it easier for operators to weld the cabinet.)

[0052] After welding is completed, the second electromagnet 28 and the third electromagnet 32 ​​are de-energized. The output shaft of the second motor 10 is controlled to rotate in reverse, causing the first adsorption frame 27 and the second adsorption frame 31 to return to their initial state. At the same time, the first electromagnet 9 is de-energized, and the first motor 5 drives the adsorption plate 7 to rise, allowing the welded cabinet to be removed.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
