Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, and particularly relates to an assembled switch cabinet frame. Background Art

[0002] The main function of a switch cabinet is to switch on and off, control and protect electrical equipment during the processes of power generation, power transmission, power distribution and power conversion in a power system. The components inside the switch cabinet mainly include a circuit breaker, a disconnector, a load switch, an operating mechanism, an instrument transformer, and various protection devices, etc. It is mainly applicable to various different occasions such as power plants, substations, petrochemical industries, metallurgical rolling mills, light industry textiles, factories and mines, residential communities, high-rise buildings, etc. The switch cabinet includes a frame, a housing arranged on the frame, and a cabinet door arranged on the frame. The structural design of the frame of the existing switch cabinet is relatively complex, with high production costs, cumbersome assembly, and the connection between the upright columns and the cross beams of the frame is not compact, resulting in poor strength of the overall switch cabinet frame. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide an assembled switch cabinet frame with a simple structure, stable and reliable performance, convenient assembly and high strength.

[0004] To achieve the above purpose, the utility model adopts an assembled switch cabinet frame, which includes four upright columns, four lower cross beams arranged at one ends of the four upright columns, two side cross beams arranged between the four upright columns, two upper cross beams arranged at the other ends of the four upright columns, and two strengthening cross beams. A pressing block is respectively arranged inside each of the four upright columns, and a plug is respectively arranged on the upright column to cover the pressing block. Both ends of the two upper cross beams are provided with fixing plates that cooperate with the pressing blocks inside the four upright columns, and bolts connected to the pressing blocks are arranged on the fixing plates. Four supporting plates are arranged on the upright columns at positions corresponding to the two strengthening cross beams, and the upper ends of the four supporting plates respectively abut against both ends of the two strengthening cross beams.

[0005] The beneficial effects of the above structure are as follows: A pressing block connected to the upper cross beam is arranged inside the upright column, so as to ensure that the connection between the upright column and the upper cross beam is more compact and firm. The plug is clamped on the upright column, and the assembly is more convenient. The supporting plate plays a supporting role for the strengthening cross beam, which is beneficial to improving the overall strength of the frame body. Therefore, the assembled switch cabinet frame has the advantages of simple structure, stable and reliable performance, convenient assembly and high strength.

[0006] Particularly, a top plate is arranged on the two upper cross beams and the two strengthening cross beams, and flanges wrapping the two strengthening cross beams are respectively arranged at both ends of the top plate. The two ends of the top plate wrap the two strengthening cross beams, so as to ensure that the connection between the top plate and the strengthening cross beam is more compact, which is beneficial to improving the overall strength of the switch cabinet frame.

[0007] In particular, one end of the plug has a cover plate portion that is engaged within the upright column and covers the pressing block. The other end of the plug is vertically bent to form an insertion plate portion. A slot that cooperates with the insertion plate portion is provided on the upright column. The insertion plate portion is inserted into the slot, and a snap-fit connection between the insertion plate and the upright column is formed. The plug and the upright column are connected by a snap-fit connection method, which facilitates the assembly of the plug and the upright column and has a higher assembly efficiency.

[0008] In particular, four L-shaped brackets are provided at the two ends of the two side crossbeams corresponding to the four upright columns. One end of the L-shaped bracket is fixed to the upright column, and the other end of the L-shaped bracket is fixed to the side crossbeam. The L-shaped bracket strengthens the side crossbeam, thereby ensuring a more secure connection between the upright column and the side crossbeam.

[0009] In particular, four triangular plates are provided between the four upright columns and the four lower crossbeams. One end of the triangular plate is fixed to the upright column, and the other end of the triangular plate is fixed to the lower crossbeam. The triangular plate can play a supporting role, ensuring a more secure connection between the four upright columns and the four lower crossbeams, which is beneficial to improving the overall strength of the switch cabinet frame.

[0013] Such as Figures 1 to 3As shown in the figure, an embodiment of the utility model is an assembled switch cabinet frame, which includes four columns 10, four lower cross beams 11 arranged at one end of the four columns 10, two side cross beams 12 arranged between the four columns 10, two upper cross beams 13 and two strengthening cross beams 14 arranged at the other end of the four columns 10. A pressing block 15 is respectively arranged in each of the four columns 10, and a plug 16 covering the pressing block 15 is respectively arranged on the columns 10. Both ends of the two upper cross beams 13 are provided with fixing plates 131 that cooperate with the pressing blocks 15 in the four columns 10. Bolts connected to the pressing blocks 15 are arranged on the fixing plates 131. Four supporting plates 17 are arranged on the columns 10 at positions corresponding to the two strengthening cross beams 14 on the fixing plates 131. The upper ends of the four supporting plates 17 respectively abut against both ends of the two strengthening cross beams 14. A top plate 18 is arranged on the two upper cross beams 13 and the two strengthening cross beams 14. Flanges 181 covering the two strengthening cross beams 14 are respectively arranged at both ends of the top plate 18. The two ends of the top plate are wrapped on the two strengthening cross beams, so as to ensure that the connection between the top plate and the strengthening cross beam is more compact, which is beneficial to improving the overall strength of the switch cabinet frame. One end of the plug 16 has a cover plate portion 161 that is clamped in the column 10 and covers the pressing block 15. The other end of the plug 16 is vertically bent to form a plug portion 162. A slot 101 that cooperates with the plug portion 162 is arranged on the column 10. The plug portion 162 is inserted into the slot 101, and the plug portion 162 and the column 10 form a clamping fit.
