Description

Technical Field

[0001] This utility model relates to an indoor screen cabinet bracket, and more particularly to an indoor screen cabinet bracket with bolt connection. Background Technology

[0002] The secondary equipment in a substation primarily protects and controls the primary equipment. By collecting current and voltage readings and the location information of the primary equipment, it identifies the location of faults and accurately and quickly responds to them, ensuring the safety of the primary equipment and guaranteeing the reliability of the power supply system. The substation secondary system mainly includes: system relay protection, system dispatch automation, communication systems, substation automation systems, component protection and automatic devices, and other secondary systems. To prevent the adverse effects of static electricity on the secondary equipment, and considering the cable laying, connection, and maintenance beneath the equipment, the secondary equipment room requires an anti-static floor.

[0003] Conventional indoor display cabinet brackets are typically constructed by welding channel steel and steel plates. A continuous channel steel is laid on top of the bracket, with holes in the web or flanges of the channel steel for mounting and fixing the upper display cabinet. This type of bracket has the following disadvantages:

[0004] 1. During the construction of the support structure, there are a large number of on-site welding operations, which will generate pollution such as arc radiation, harmful dust, toxic gases, high-frequency electromagnetic fields, radiation and noise, affecting the normal operation of electrical equipment and posing potential risk factors.

[0005] 2. The support frame has poor independence. When expanding the cabinet space later, the construction of new support frames will have a significant impact on the existing support frames and the upper cabinets, and may require a power outage in the secondary equipment room.

[0006] 3. The support structure did not take into account the support of the surrounding anti-static floor, so additional support columns need to be added at the joint between the floor and the support structure, which increases the complexity of construction. Utility Model Content

[0007] Purpose of the utility model: The purpose of this utility model is to propose an indoor screen cabinet bracket with bolt connection, which avoids welding work during on-site bracket construction, while enhancing the independence of the bracket and taking into account the support of the anti-static floor around the bracket.

[0008] Technical solution: This utility model includes columns, which are arranged at the four corners of the support. Adjacent columns are connected by bolts with crossbeams and flange beams. The crossbeams are arranged inside the columns, and the crossbeams around the perimeter form the internal support of the support. The flange beams are located on the perimeter of the columns, and the flange beams around the perimeter form the external support of the support, which is used to support the antistatic floor near the support.

[0009] The crossbeam includes a first crossbeam and a second crossbeam. The first crossbeam is arranged horizontally, and the second crossbeam is arranged vertically. The first crossbeam is perpendicular to the second crossbeam. The flange beam includes a first flange beam and a second flange beam. The first flange beam is arranged corresponding to the first crossbeam, and the second flange beam is arranged corresponding to the second crossbeam.

[0010] The first crossbeam is connected to the column by a first diagonal brace, and the second crossbeam is connected to the column by a second diagonal brace.

[0011] There is a height difference between the top of the flange beam and the top of the column. This height difference is adapted to the thickness of the antistatic floor, ensuring that the antistatic floor is flush with the top surface of the column after it is laid.

[0012] The vertical side length of the crossbeam is greater than the sum of the vertical side length of the flange beam and the thickness of the antistatic floor, in order to match the installation of the cabinet.

[0013] The horizontal side length of the crossbeam is adapted to the frame size at the bottom of the cabinet to ensure that the internal space is not obstructed after the cabinet is in place.

[0014] There is a gap of at least 10mm between the inner side of the column and the crossbeam.

[0015] The columns, first crossbeam, second crossbeam, first flange beam, second flange beam, first diagonal brace, and second diagonal brace are all made of angle steel.

[0016] Each column has a base plate welded to its bottom, and this welding is completed before the column leaves the factory.

[0017] Beneficial effects: The bolt-connected indoor cabinet support of this utility model uses bolts to connect all components, eliminating the need for on-site welding. The support is also highly independent, allowing for batch independent replication when expanding cabinet space. Angle steel flanges are installed around the support to firmly support the nearby anti-static floor, resulting in a more aesthetically pleasing finished product. This support, while ensuring reasonable structural stress, overcomes the shortcomings of traditional indoor cabinet supports. Attached Figure Description

[0019] Figure 2 This is a front view of the present invention;

[0020] Figure 3 This is a side view of the present invention. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1-3As shown, the bolted indoor cabinet support in this embodiment includes a column 1, a first crossbeam 2, a second crossbeam 3, a first flange beam 4, a second flange beam 5, a first diagonal brace 6, a second diagonal brace 7, a pad 8, and connecting bolts 9; the column 1, the first crossbeam 2, the second crossbeam 3, the first flange beam 4, the second flange beam 5, the first diagonal brace 6, and the second diagonal brace 7 are all made of angle steel.

[0023] like Figure 1 As shown, the columns 1 are arranged at the four corners of the support frame. Each column 1 has a base plate 8 welded to its bottom, and this welding is completed before the column 1 leaves the factory. Adjacent columns 1 are connected by bolts 9 with crossbeams and flange beams. The crossbeams are arranged inside the column 1, and the crossbeams around the perimeter form the internal support of the support frame. The flange beams are located on the perimeter of the column 1, and the flange beams around the perimeter form the external support of the support frame.

[0024] like Figure 2 and Figure 3 As shown, the crossbeams include a first crossbeam 2 and a second crossbeam 3. The first crossbeam 2 is horizontally arranged, and the second crossbeam 3 is vertically arranged. The first crossbeam 2 and the second crossbeam 3 are perpendicular to each other. The flanged beams include a first flanged beam 4 and a second flanged beam 5. The first flanged beam 4 is arranged corresponding to the first crossbeam 2, and the second flanged beam 5 is arranged corresponding to the second crossbeam 3. The first flanged beam 4 and the second flanged beam 5 can support the anti-static floor near the bracket, avoiding the need for additional support columns and resulting in a more aesthetically pleasing finish. A first diagonal brace 6 connects the first crossbeam 2 to the column 1, and a second diagonal brace 7 connects the second crossbeam 3 to the column 1.

[0025] There is a height difference between the top of the flanged beams around the support frame and the top of column 1. This height difference is adapted to the thickness of the anti-static floor to ensure that the anti-static floor is flush with the top surface of column 1 after installation. The vertical side length of the crossbeam is slightly longer than the sum of the vertical side length of the flanged beam and the thickness of the anti-static floor to match the installation of the cabinet. The horizontal side length of the crossbeam should be adapted to the dimensions of the frame at the bottom of the cabinet to ensure that the internal space is not obstructed after the cabinet is in place.

[0026] After the bracket is installed, a 10mm gap is left between the column 1 and the inner sides of the first crossbeam 2 and the second crossbeam 3.

[0027] All the aforementioned support components are connected by bolts, eliminating on-site welding work, thus avoiding risks and facilitating transportation. The support structure is highly independent, and can be mass-produced when expanding the cabinet space in the future, without affecting the existing support structure.
