Description

Technical Field

[0001] This invention relates to the field of electrical switchgear mounting beam technology, specifically a universal mounting beam for electrical switchgear. Background Technology

[0002] With the development of domestic power distribution technology, GGD cabinet technology has matured, with the most typical being C-type and 8MF-type profiles. There are also various types of switch mounting beams inside the cabinet. The advantage is that the structure is simple to manufacture and the combination is flexible. However, the disadvantage of traditional low-voltage switchgear is that the openings of various mounting beams are inconsistent and the production process is complicated, resulting in high production costs and inconvenience for users.

[0003] An existing patent (publication number: CN116667156A) discloses a universal mounting beam suitable for GGD cabinets, relating to the field of low-voltage switch cabinet manufacturing technology. It includes a first galvanized sheet with rectangular folds. These folds form a bottom portion, symmetrical side portions along the two long sides of the rectangular folds, and symmetrical end portions along the two short sides of the rectangular folds. The side portions are folded along the rectangular folds and then perpendicular to the bottom portion, as are the end portions. A rectangular hole is provided at the intersection of the bottom portion, end portions, and side portions. By setting the rectangular folds, workers can use a CNC punch press to bend the rectangular folds, thereby achieving rapid fabrication of the mounting beam. A drilling machine is used to drill holes in the first galvanized sheet to ensure consistent hole placement, facilitating subsequent installation.

[0004] However, the above technical solution still has certain defects. The creases in the above technical solution make it easier for workers to bend the installation beam, but this also makes the strength of the creases on the installation beam weak, so that the installation beam is prone to breakage at the creases during use. Therefore, a universal installation beam for electrical switchgear is proposed. Summary of the Invention

This increases the distance between the electrical switches, thereby preventing the heat generated by the various electrical switches from accumulating during use and improving the airflow inside the switch cabinet.

[0019] 3. This invention inserts the upper connecting column on one set of mounting beams into the lower connecting sleeve on another set of mounting beams, and limits the movement between the upper connecting column and the lower connecting sleeve using limiting pins and limiting grooves, thereby enabling the two sets of mounting beams to be connected and combined, allowing multiple sets of mounting beams to be used in combination, thus improving the flexibility of the mounting beams during use.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following describes embodiments of the present invention based on its overall structure. A universal mounting beam for electrical switchgear, such as... Figures 1 to 7As shown, the system includes an upper beam 1, which includes a sleeve 101. A bidirectional threaded rod 102 is rotatably connected to the inner wall of the sleeve 101. Two sets of threaded sleeves 103 are threadedly connected to the outer wall of the bidirectional threaded rod 102. A set of sliding rods 104 is fixedly connected to the outer wall of each set of threaded sleeves 103. The sliding rods 104 are slidably connected to the inner wall of the sleeve 101, with one end of the sliding rod 104 located outside the sleeve 101. Two sets of pins 112 are fixedly connected to the outer end of the sliding rod 104. A first bevel gear 110 is rotatably connected to the inner wall of the sleeve 101. The bidirectional threaded rod 102... The outer wall of the sleeve 101 is fixedly fitted with a second bevel gear 111, which meshes with the first bevel gear 110 and the second bevel gear 111. A fixing plate 105 is fixedly connected to the side wall of the sleeve 101. Multiple sets of guide grooves 106 are fixedly connected to the side wall of the fixing plate 105. Two sets of air guide covers 107 are fixedly connected to the top of the sleeve 101. The two sets of air guide covers 107 are respectively connected to multiple sets of guide covers. Multiple sets of air collecting covers 108 are fixedly connected to the side of the sleeve 101 away from the fixing plate 105. The multiple sets of air collecting covers 108 are respectively connected to the two sets of air guide covers 107. A set of fans 109 are installed on the inner wall of each set of air collecting covers 108.

[0033] By using a wrench to rotate the first bevel gear 110, the first bevel gear 110 drives the second bevel gear 111, and the second bevel gear 111 drives the bidirectional threaded rod 102 to rotate, causing the bidirectional threaded rod 102 to push the two sets of sliding rods 104 away from each other, so that the sliding rods 104 extend out of the sleeve 101, and the pins 112 at the ends of the two sets of sleeves 101 can be inserted into the bolt holes in the inner wall of the switch cabinet, so that the mounting beam can adapt to switch cabinets of different sizes. The electrical switch is fixed to the side wall of the fixing plate 105 with bolts. The fan 109 draws air into the air guide cover 107, and then this airflow enters the air collector shroud 108 and is pushed out of the air collector shroud 108 by the fan 109, so that a large amount of airflow passes through the air guide shroud, and the heat emitted by the electrical switch is discharged.

[0034] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The bottom end of the sleeve 101 is provided with a lower beam 2, which includes multiple sets of top rods 201. Each set of top rods 201 is located near two sets of sliding rods 104, and two sets of top rods 201 are located next to each set of sliding rods 104. The top ends of the multiple sets of top rods 201 are rotatably connected to the bottom end of the sleeve 101. Two sets of connecting rods 202 are fixedly connected to the bottom end of each set of top rods 201. A set of tie rods 207 is hinged to the side wall of each set of connecting rods 202. The top of the multiple sets of tie rods 207... The ends are respectively hinged to the ends of two sets of sliding rods 104. The outer wall of the multiple sets of connecting rods 202 is slidably fitted with a sliding frame 203. The bottom end of the sliding frame 203 is fixedly connected to a lower support plate 204. The side wall of the lower support plate 204 is fixedly connected to a lower mounting plate 208. The two ends of the lower support plate 204 are respectively fixedly connected to two sets of guide posts 205. The outer wall of each set of guide posts 205 is slidably fitted with a set of sliding sleeves 206. The multiple sets of sliding sleeves 206 are fixedly connected to the side wall of the sleeve 101.

[0035] As the two sets of sliding rods 104 move away from each other, the sliding rod 104 pulls the pull rod 207, causing the pull rod 207 to pull the top rod 201 to flip. During the flipping process, the top rod 201 drives the connecting rod 202 to flip, causing the connecting rod 202 to slide on the inner wall of the sliding frame 203. The movement trajectory of the connecting rod 202 during the flipping process driven by the top rod 201 is arc-shaped, thereby pushing the sliding frame 203 to move downward. The sliding frame 203 drives the lower support plate 204 to move downward, causing the sliding frame 203 to drive the guide post 205 to slide downward. The process of the guide post 205 sliding downward inside the sliding sleeve 206 increases the distance between the lower mounting plate 208 and the fixed plate 105. Some electrical switches are fixed to the lower mounting plate 208 by bolts. During the above process, the spacing between the electrical switches on the lower mounting plate 208 increases.

[0036] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Two sets of connecting components 3 are fixedly connected to the outer wall of the upper beam 1. The connecting components 3 include an upper connecting column 301 and a lower connecting sleeve 302. The upper connecting column 301 is fixedly connected to the top end of the sleeve 101 and is close to the end of the sleeve 101. The lower connecting sleeve 302 is fixedly connected to the bottom end of the lower support plate 204 and the position of the lower connecting sleeve 302 is aligned with the position of the upper connecting column 301. Two sets of rotating arms 303 are rotatably connected to the inner wall of the upper connecting column 301 and the two sets of rotating arms 303 are coaxially connected. A set of limiting pins 304 is fixedly connected to the top end of each set of rotating arms 303. Two sets of limiting grooves 305 are opened on the inner wall of the lower connecting sleeve 302. The limiting grooves 305 match the limiting pins 304. A lever 306 is fixedly connected to the bottom end of the rotating arm 303. A rubber sleeve is fixedly fitted on the outer wall of the lever 306. A torsion spring is provided between the two sets of rotating arms 303.

[0037] By inserting the upper connecting post 301 on one set of mounting beams into the lower connecting sleeve 302 on another set of mounting beams, and pushing the lever 306 during this process, the two sets of rotating arms 303 are flipped and the torsion spring is twisted, so that the limiting pins 304 at the ends of the two sets of rotating arms 303 slide into the upper connecting post 301. After the upper connecting post 301 is fully inserted into the lower connecting sleeve 302, the lever 306 is released, causing the torsion spring to rebound, so that the rotating arm 303 flips back to its original position. During the flipping and resetting process of the rotating arm 303, the limiting pin 304 is reset, so that the limiting pin 304 is inserted into the lower inner sleeve, so that the upper connecting post 301 and the lower connecting sleeve 302 cannot be separated, and the two sets of mounting beams can be connected together.

[0038] In use, the sliding rod 104 is pushed out of or into the sleeve 101 by the bidirectional threaded rod 102, so that the pin 112 at the end of the sliding rod 104 is inserted into the threaded hole inside the switch cabinet. This allows the entire mounting beam to adapt to switch cabinets of different widths, and also ensures the strength of the mounting beam, improves the service life of the mounting beam, and avoids the mounting beam from breaking during use. The parts not mentioned in this device are the same as or can be implemented using existing technology.
