Abstract
Description
Technical Field
[0001] This application relates to the field of electrical equipment installation technology, and in particular to a disconnector mounting bracket for a subway cross-line power supply system. Background Technology
[0002] Currently, in subway over-line power supply systems, disconnect switches, as an important component of electrical equipment, are mainly used to isolate power during maintenance or repair to ensure the safety of personnel. Disconnect switches are usually installed on mounting brackets.
[0003] Traditional disconnector mounting brackets are assembled from numerous parts on-site in subway cross-line power supply systems. Even a slight error in any part (e.g., dimensional inaccuracies) can affect the overall installation performance. Therefore, to ensure proper installation, repeated adjustments and calibrations are required after assembly, wasting time and labor, thus reducing assembly efficiency. Subway renovation projects have shorter construction periods; wasting too much time on bracket assembly could prevent on-time completion and disrupt line operation. Furthermore, traditional assembled disconnector mounting brackets are prone to deformation when used for cross-line installations with large spans, affecting the normal operation of the disconnectors and other electrical equipment. Therefore, this application proposes a disconnector mounting bracket for subway cross-line power supply systems. Utility Model Content

The installation positions of the first and third mounting brackets on the bearing piles are predetermined. After installation, only a first flange connects the second mounting bracket between the two first mounting brackets, and a second flange connects the fourth mounting bracket between the two third mounting brackets.

Furthermore, the length and number of the second mounting brackets can be adjusted based on the distance between the closest ends of the two first mounting brackets, and the length and number of the fourth mounting brackets can be adjusted based on the distance between the closest ends of the two third mounting brackets. This modular assembly of the disconnector mounting bracket, along with the flange connection method, makes the installation and disassembly of the disconnector support bracket more convenient, thereby improving the installation efficiency of the disconnector mounting bracket.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0038] refer to Figures 1 to 4 This application provides a disconnector mounting bracket for a subway overpass power supply system. The bracket is installed on two support piles 100, both positioned on a reference surface at a preset distance. The reference surface can be the horizontal plane where the subway overpass power supply system is located. Both the reference surface and the preset distance can be set according to actual conditions; therefore, this application does not specifically limit them. Furthermore, the support piles 100 are made of reinforced concrete and are fixedly connected to the reference surface. The disconnector mounting bracket of this application includes:
[0039] Two first mounting brackets 200 are respectively installed on the upper sections of two bearing piles 100, and their adjacent ends are connected to second mounting brackets 400 via first flanges 300. Both the first mounting brackets 200 and the second mounting brackets 400 are used to install disconnect switches 500. The two first mounting brackets 200 are fixedly installed on the upper sections of the bearing piles 100, while the length and number of the second mounting brackets 400 can be adjusted according to the distance between the adjacent ends of the two first mounting brackets 200, thereby enabling modular installation of the second mounting brackets 400 between the two first mounting brackets 200. Figure 1 The diagram shows two first mounting brackets 200 connected by a first flange 300, with a second mounting bracket 400. Multiple second mounting brackets 400 can be present, depending on the distance between the adjacent ends of the two first mounting brackets 200. Furthermore, one or more disconnecting switches 500 can be mounted on each first mounting bracket 200 and second mounting bracket 400. The specific number of disconnecting switches 500 can be set according to actual needs, and this application does not impose a specific limitation thereon. The disconnecting switch 500 can be fixedly connected to the first mounting bracket 200 or the second mounting bracket 400 via a first mounting base.
[0040] Two third mounting brackets 600 are respectively installed on the lower sections of the two bearing piles 100, and their adjacent ends are connected to a fourth mounting bracket 800 via a second flange 700. Both the two third mounting brackets 600 and the fourth mounting bracket 800 are used to install the mechanism housing 900. The two third mounting brackets 600 are fixedly installed on the lower sections of the bearing piles 100, while the length and number of the fourth mounting brackets 800 can be adjusted according to the spacing between the adjacent ends of the two third mounting brackets 600, thereby enabling modular installation of the fourth mounting brackets 800 between the two third mounting brackets 600. Figure 1 The diagram shows a fourth mounting bracket 800 connected between two third mounting brackets 600 via a second flange 700. Multiple fourth mounting brackets 800 can be present, depending on the spacing between the adjacent ends of the two third mounting brackets 600. Furthermore, one or more disconnecting switches 500 can be mounted on each third mounting bracket 600 and fourth mounting bracket 800. The specific number of disconnecting switches 500 can be set according to actual needs, and this application does not impose a specific limitation thereon. The mechanism housing 900 can be fixedly connected to the third mounting bracket 600 or the fourth mounting bracket 800 via a second mounting base.
[0041] Each disconnector switch 500 corresponds to a mechanism box 900, and its input end is connected to the output end of the mechanism box 900 via an operating lever. The mechanism box 900 contains a motor and transmission devices such as gears, worm gears, and worm shafts. The specific process of the mechanism box 900 and its operation of the disconnector switch 500 via the operating lever 1000 can be found in existing mechanism boxes 900 and their operating principles; this application does not impose specific limitations on them.
[0042] The metro overpass power supply system mounting bracket provided in this application consists of two bearing piles 100 spaced at a preset distance on a reference surface. A first mounting bracket 200 is installed on the upper section of each of the two bearing piles 100. A second mounting bracket 400 is connected between the two first mounting brackets 200 via a first flange 300. An isolating switch 500 is mounted on both the first and second mounting brackets 200. Furthermore, a third mounting bracket 600 is installed on the lower section of each of the two bearing piles 100. A fourth mounting bracket 800 is connected between the two third mounting brackets 600 via a second flange 700. A mechanism box 900 is mounted on both the third and fourth mounting brackets 600. The output end of each mechanism box 900 is connected to the input end of its corresponding isolating switch 500 via an operating lever 1000, thereby ensuring the normal operation of the metro overpass power supply system.
[0043] Compared to the traditional method of assembling parts on-site for subway overpass power supply systems, the first mounting bracket 200, second mounting bracket 400, third mounting bracket 600, and fourth mounting bracket 800 in this application are all integral units. The installation positions of the first mounting bracket 200 and the third mounting bracket 600 on the bearing pile 100 are fixed. After installation, it is only necessary to connect the second mounting bracket 400 between the two first mounting brackets 200 through the first flange 300, and connect the fourth mounting bracket 800 between the two third mounting brackets 600 through the second flange 700. This avoids deformation of the disconnector mounting bracket and ensures the normal operation of the disconnector switch 500 and the mechanism box 900 on the mounting bracket. Furthermore, the length and number of the second mounting bracket 400 can be adjusted according to the distance between the two first mounting brackets 200 at their closest ends, and the length and number of the fourth mounting bracket 800 can be adjusted according to the distance between the two third mounting brackets 600 at their closest ends, thereby realizing the modular assembly of the disconnector mounting bracket. Moreover, the flange connection method mentioned above makes the installation and disassembly process of the disconnector mounting bracket more convenient, thereby improving the installation efficiency of the disconnector mounting bracket.
[0044] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 Each first mounting bracket 200 in this application includes two first upper mounting plates 201 and two first lower mounting plates 202 located directly below the two first upper mounting plates 201. Specifically, the two first upper mounting plates 201 are parallel to each other and located in the same horizontal plane, and the two first lower mounting plates 202 are parallel to each other and located in the same horizontal plane. Each first upper mounting plate 201 and each first lower mounting plate 202 is provided with a first flange 300 at both ends. The two first upper mounting plates 201 and the two first lower mounting plates 202 are connected by a first reinforcing plate 203. The upper and lower sides of the first reinforcing plate 203 are welded to the two first upper mounting plates 201 and the two first lower mounting plates 202, respectively. The first reinforcing plate 203 makes the connection between the two first upper mounting plates 201 and the two first lower mounting plates 202 more stable, thereby improving the overall stability of the first mounting bracket 200.
[0045] In addition, a first through hole 2031 is provided on the first reinforcing plate 203. The number of first through holes 2031 can be multiple, and the number and shape of the first through holes 2031 can be set according to actual needs; this application does not impose specific limitations on them here. Specifically, the provision of the first through hole 2031 not only reduces the overall weight of the first mounting frame 200, but also facilitates the lifting of the first mounting frame 200 during transportation to the installation site, as lifting of the first mounting frame 200 is unavoidable. The first through hole 2031 allows the hook of the lifting device to be easily attached to the first through hole 2031, facilitating lifting operations and thus improving the convenience of transporting the first mounting frame 200.
[0046] In some embodiments, reference Figure 1 and Figure 2 In this application, the first upper mounting plate 201 and the first lower mounting plate 202, which are away from the second mounting bracket 400 and have a first flange 300, are connected to a support plate 2021. The support plate 2021, which is connected to the first upper mounting plate 201 or the first lower mounting plate 202, is provided with a first flange 300. The end of the first upper mounting plate 201 and the first lower mounting plate 202 that is away from the second mounting bracket 400 is fixedly connected to the first flange 300, while the end of the support plate 2021 that is connected to the first upper mounting plate 201 and the first lower mounting plate 202 is fixedly provided with a first flange 300. The two first flanges 300 are fastened by fasteners, thereby achieving the purpose of connecting the support plate 2021 to the end of the first upper mounting plate 201 and the first lower mounting plate 202 that is away from the second mounting bracket 400, thus extending the purpose of the first upper mounting plate 201 and the first lower mounting plate 202.
[0047] Additionally, the support plate 2021 is used to install protective devices 2022 that can protect the disconnector switch 500. The shape and length of the support plate 2021 can be set according to the actual size and number of protective devices 2022 to be installed, and this application does not impose specific limitations on them. Furthermore, the support plate 2021 facilitates the placement of the protective devices 2022, which can be fixed to the support plate 2021 via a base to ensure stability. The protective devices 2022 are used to protect the disconnector switch 500 and can be surge arresters or other devices, selected according to actual needs, and this application does not impose specific limitations on them.
[0048] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 The second mounting bracket 400 in this application includes two second upper mounting plates 401 and two second lower mounting plates 402 located directly below the two second upper mounting plates 401. Specifically, the two second upper mounting plates 401 are parallel to each other and located in the same horizontal plane, and the two second lower mounting plates 402 are parallel to each other and located in the same horizontal plane. Each end of each second upper mounting plate 401 and each end of each second lower mounting plate 402 is provided with a first flange 300. The two second upper mounting plates 401 and the two second lower mounting plates 402 are connected by a second reinforcing plate 403. The upper and lower sides of the second reinforcing plate 403 are welded to the two second upper mounting plates 401 and the two second lower mounting plates 402, respectively. The second reinforcing plate 403 makes the connection between the two second upper mounting plates 401 and the two second lower mounting plates 402 more stable, thereby improving the overall stability of the second mounting bracket 400.
[0049] In addition, a second through hole 4031 is provided on the second reinforcing plate 403. The number of second through holes 4031 can be multiple, and the number and shape of the second through holes 4031 can be set according to actual needs; this application does not impose specific limitations on them. Specifically, the provision of the second through hole 4031 not only reduces the overall weight of the second mounting bracket 400, but also facilitates the lifting of the second mounting bracket 400 during transportation to the installation site, as lifting of the second mounting bracket 400 is unavoidable. The second through hole 4031 allows the hook of the lifting device to be easily attached to the second through hole 4031, facilitating lifting operations and thus improving the convenience of transporting the second mounting bracket 400.
[0050] In some embodiments, reference Figure 1 , Figure 2 and Figure 3In this application, a first reinforcing rod 404 is provided between each of the second upper mounting plates 401 and the second lower mounting plate 402 located directly below it. The first reinforcing rod 404 is obliquely connected between the second upper mounting plate 401 and the second lower mounting plate 402. The oblique placement of the first reinforcing rod 404 between the second upper mounting plate 401 and the second lower mounting plate 402 avoids stress concentration between the two plates, further improving the stability of the second mounting frame 400. The two ends of the first reinforcing rod 404 are welded to the second upper mounting plate 401 and the second lower mounting plate 402 respectively, which further ensures the overall stability of the second mounting frame 400.
[0051] In the above embodiments, since the length of the second mounting bracket 400 is less than the length of the two first mounting brackets 200, in order to ensure the stability of the second mounting bracket 400, this application provides a first reinforcing rod 404 between each second upper mounting plate 401 and the second lower mounting plate 402 located directly below it. Furthermore, the stability of the second mounting bracket 400 can be further improved by providing multiple first reinforcing rods 404, and the number of first reinforcing rods 404 can be set according to actual conditions; however, this application does not specifically limit it here.
[0052] In some embodiments, reference Figure 1 , Figure 2 and Figure 4 Each third mounting bracket 600 in this application includes two third upper mounting plates 601 and two third lower mounting plates 602 located directly below the two third upper mounting plates 601. Specifically, the two third upper mounting plates 601 are parallel to each other and located in the same horizontal plane, and the two third lower mounting plates 602 are parallel to each other and located in the same horizontal plane. A second flange 700 is provided at one end of each of the two third upper mounting plates 601 and the two third lower mounting plates 602 that are connected to the fourth mounting bracket 800. The two third upper mounting plates 601 are located away from the fourth mounting bracket 800. One end of the third mounting plate 604 is connected to the end of the two lower mounting plates 602 away from the fourth mounting bracket 800 via the third reinforcing plate 603. Multiple third reinforcing plates 603 are spaced apart between the third reinforcing plate 604 and the second flange 700. The upper and lower sides of the third reinforcing plate 603 are welded to the two upper mounting plates 601 and the two lower mounting plates 602 respectively. The third reinforcing plate 603 makes the connection between the two upper mounting plates 601 and the two lower mounting plates 602 more stable, thereby improving the overall stability of the third mounting bracket 600.
[0053] In addition, each third reinforcing plate 603 is provided with a third through hole 6031. The number of third through holes 6031 can be multiple, and their number and shape can be set according to actual needs; this application does not impose specific limitations on them. Specifically, the provision of the third through hole 6031 not only reduces the overall weight of the third mounting bracket 600, but also facilitates the lifting of the third mounting bracket 600 during transportation to the installation site, as lifting of the third mounting bracket 600 is unavoidable. The third through hole 6031 allows the hook of the lifting device to be easily attached, facilitating lifting operations and improving the convenience of transporting the third mounting bracket 600.
[0054] In some embodiments, reference Figure 1 , Figure 2 and Figure 4 The fourth mounting bracket 800 in this application includes two upper fourth mounting plates 801 and two lower fourth mounting plates 802 located directly below the upper fourth mounting plates 801. The upper fourth mounting plates 801 are parallel to each other and located in the same horizontal plane, and the lower fourth mounting plates 802 are parallel to each other and located in the same horizontal plane. A second flange 700 is provided at both ends of each upper fourth mounting plate 801 and each lower fourth mounting plate 802. The upper and lower fourth mounting plates 801 and the lower fourth mounting plates 802 are connected by a fourth reinforcing plate 803. The upper and lower sides of the fourth reinforcing plate 803 are welded to the upper and lower fourth mounting plates 801 and the lower fourth mounting plates 802, respectively. The fourth reinforcing plate 803 makes the connection between the upper and lower fourth mounting plates 801 and the lower fourth mounting plates 802 more stable, thereby improving the overall stability of the fourth mounting bracket 800.
[0055] In addition, a fourth through hole 8031 is provided on the fourth reinforcing plate 803. The number of fourth through holes 8031 can be multiple, and the number and shape of the fourth through holes 8031 can be set according to actual needs; this application does not impose specific limitations on them. Specifically, the provision of the fourth through hole 8031 not only reduces the overall weight of the fourth mounting bracket 800, but also facilitates the lifting of the fourth mounting bracket 800 during transportation to the installation site, as lifting of the fourth mounting bracket 800 is unavoidable. The fourth through hole 8031 allows the hook of the lifting device to be easily attached to the fourth through hole 8031, facilitating lifting operations and thus improving the convenience of transporting the fourth mounting bracket 800.
[0056] In some embodiments, reference Figure 1 , Figure 2 and Figure 4In this application, a second reinforcing rod 804 is provided between each of the fourth upper mounting plates 801 and the fourth lower mounting plate 802 located directly below it. The second reinforcing rod 804 is obliquely connected between the fourth upper mounting plate 801 and the fourth lower mounting plate 802. The oblique placement of the second reinforcing rod 804 between the fourth upper mounting plate 801 and the fourth lower mounting plate 802 avoids stress concentration on the fourth upper mounting plate 801 and the fourth lower mounting plate 802, further improving the stability of the fourth mounting frame 800. The two ends of the second reinforcing rod 804 are welded to the fourth upper mounting plate 801 and the fourth lower mounting plate 802 respectively, which further ensures the overall stability of the fourth mounting frame 800.
[0057] In the above embodiments, since the length of the fourth mounting bracket 800 is less than the length of the two third mounting brackets 600, in order to ensure the stability of the fourth mounting bracket 800, this application provides a second reinforcing rod 804 between each fourth upper mounting plate 801 and the fourth lower mounting plate 802 located directly below it. Furthermore, the stability of the fourth mounting bracket 800 can be further improved by providing multiple second reinforcing rods 804, and the number of second reinforcing rods 804 can be set according to actual conditions; however, this application does not specifically limit it here.
[0058] In some embodiments, the two first mounting brackets 200 and the two fourth mounting brackets 800 in this application are all mounted on the two bearing piles 100 by mounting plate 1001; the mounting plate 1001 is fixed to the bearing pile by anchor bolts (e.g., pre-embedded M16 anchor bolts), and the two first mounting brackets 200 and the two fourth mounting brackets 800 are then fixedly connected to the mounting plate 1001 by anchor bolts, etc., which improves the stability of the first mounting brackets 200 and the third mounting bracket 600 after installation.
[0059] Furthermore, the first mounting bracket 200, the second mounting bracket 400, the two third mounting brackets 600, the fourth mounting bracket 800, and the mounting plate 1001 are all made of Q235B material. Q235B possesses superior properties such as high strength, good plasticity and toughness, excellent weldability, and low cost. This results in a higher degree of lightness and strength in the first mounting bracket 200, second mounting bracket 400, two third mounting brackets 600, fourth mounting bracket 800, and mounting plate 1001 made of Q235B material, thereby extending their service life and ensuring the stability of the disconnector switch 500 after installation.
[0060] In some embodiments, the outer surfaces of the two first mounting brackets 200, the second mounting bracket 400, the two third mounting brackets 600, and the fourth mounting bracket 800 in this application are all provided with a rust-proof layer of a predetermined thickness; wherein, the rust-proof layer is made of hot-dip galvanized material, specifically, during the processing of the two first mounting brackets 200, the second mounting bracket 400, the two third mounting brackets 600, and the fourth mounting bracket 800 are respectively immersed in molten zinc, so that zinc reacts chemically with iron to form a dense zinc-iron alloy layer (such as α phase, β phase, γ phase, etc.) on the steel surface, while simultaneously covering a pure... The zinc layer, a zinc-iron alloy layer, not only provides physical insulation but also prevents oxygen and moisture from contacting the first mounting bracket 200, the second mounting bracket 400, the third mounting bracket 600, and the fourth mounting bracket 800. It also provides electrochemical protection. When the zinc layer is damaged, zinc acts as a sacrificial anode and preferentially corrodes, thus protecting the first mounting bracket 200, the second mounting bracket 400, the third mounting bracket 600, and the fourth mounting bracket 800 from further corrosion, thereby improving their service life.
[0061] In addition, the preset thickness is greater than or equal to 85μm. This is to ensure that the surfaces of the first mounting bracket 200, the second mounting bracket 400, the third mounting bracket 600 and the fourth mounting bracket 800 have sufficient corrosion resistance under various environmental conditions, while meeting the requirements of industry standards (e.g., GB / T 13912-2002) and specifications. This thickness of anti-rust layer can ensure the long-term durability of the first mounting bracket 200, the second mounting bracket 400, the third mounting bracket 600 and the fourth mounting bracket 800, while balancing economic benefits and construction convenience.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
