Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and more specifically, to a wiring device spanning a suspension frame. Furthermore, this utility model also relates to a maglev train including the aforementioned wiring device spanning a suspension frame. Background Technology

[0002] Medium- and low-speed maglev vehicles are a new type of transportation. Their most distinctive feature is that they eliminate the wheels of traditional vehicles. By controlling the suspension gap between the suspension frame and the F-rail, maglev trains achieve non-adhesive traction and non-contact operation.

[0003] The underframe routing mechanism includes components such as the suspension frame, suspension electromagnets, and traction linear motors. The suspension frame is mounted on the F-rail, and the suspension electromagnets and traction linear motors are mounted on the suspension frame. Fixing the suspension electromagnet cables and the three-phase motor cables of the traction linear motors on the suspension frame is a crucial aspect of medium- and low-speed maglev cabling. The routing and fixing of the cables crossing the suspension frame directly affects the quality, lifespan, and aesthetics of the cabling.

[0004] In addition, there are certain joint friction issues between the cables. Also, when the maglev train passes through curves with small radii, the movable slide has lateral displacement relative to the car body. Taking the smallest curve of R100 as an example, the maximum sliding amount of the slide is 158mm. Therefore, the cable spanning the suspension frame is also considered a dynamic cable. Existing maglev trains use conventional wiring methods, which will pull on the cables when the train is running, affecting the service life of the cables.

[0005] In conclusion, how to extend the service life of cables is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The core of this utility model is to provide a wiring device that spans a suspension frame. This device can realize the wiring of cables and can reserve a certain amount of slack for the cables, thereby extending the service life of the cables.

[0033] Another core aspect of this invention is to provide a magnetic levitation train that includes the aforementioned wiring device spanning the suspension frame.

[0034] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] The present application provides a wiring device that spans a suspension frame, comprising: a first support assembly 1 and a second support assembly 4;

[0036] The first bracket assembly 1 is disposed on the slide beam 2, and the first bracket assembly 1 is used to fix the first end of the cable 3 on the slide beam 2.

[0037] The second support assembly 4 is located on the suspension frame longitudinal beam 5. The second support assembly 4 is used to fix the second end of the cable 3 on the suspension frame longitudinal beam 5. The cable 3 between the first support assembly 1 and the second support assembly 4 is in a relaxed and bent state.

[0038] Specifically, the structure of the sliding table crossbeam 2 and the suspension frame longitudinal beam 5 can be referred to in the appendix. Figure 1Generally, multiple sliding beams 2 and suspension frame longitudinal beams 5 are arranged sequentially. This application describes a partial structure, namely two suspension frame longitudinal beams 5 and one sliding beam 2. The sliding beam 2 can be regarded as a plate-shaped component with a certain thickness. The first support component 1 is installed on the side of the sliding beam 2, and the second support component 4 is installed on the suspension frame longitudinal beam 5. The cable 3 is clamped and fixed by the first support component 1 and the second support component 4. During the installation process, the cable 3 should be in a relaxed and bent state, but its bending degree should not be too large. Since the sliding beam 2 has a certain lateral displacement relative to the vehicle body during the operation of the maglev train, the cable 3 will be pulled during the lateral displacement. When the cable 3 is in a taut state and is pulled, it will affect the internal structure of the cable 3 and reduce the service life of the cable 3. The cable 3 is in a relaxed state, which can ensure the mobility of the cable 3 and improve the aesthetics.

[0039] Based on the above embodiment, there are two first bracket assembly 1 and two second bracket assembly 4, with the two first bracket assemblies 1 disposed between the two second bracket assemblies 4, and the cable 3 is in a relaxed and bent state.

[0040] Specifically, both first support assemblies 1 are mounted on the same side wall of the slide beam 2, and are positioned near the end of the side wall of the slide beam 2. In a partial structure of this application, there are two first support assemblies 1 and two second support assemblies 4. Figure 1 Appendix Figure 2 In this configuration, two first support assemblies 1 are positioned between two second support assemblies 4. Three cables 3 are provided, passing through the first support assembly 1 and the second support assembly 4. It should be noted that the cables 3 between the first support assembly 1 and the second support assembly 4 are in a slack state, as are the cables 3 between the two first support assemblies 1. When the slide beam 2 undergoes lateral displacement relative to the vehicle body, the cables 3 can slide and stretch between the first support assembly 1 and the second support assembly 4 without affecting the internal structure of the cables 3, thus extending the service life of the cables 3.

[0041] To explain the above process with specific numerical values: When the maglev train passes through a small curve radius, such as a small radius curve of track R100, the displacement of the slide relative to the car body is 158mm. Considering that the cable 3 between the suspension frame longitudinal beam 5 and the slide crossbeam 2 cannot be straightened, it is necessary to leave a margin for the extension cable length caused by the movement of the slide. After three-dimensional data analysis, the length of the cable harness spanning the suspension frame is 1900mm.

[0042] In some embodiments, the first bracket assembly 1 includes a first bracket 101, a first motor cable clamp 102, a first bracket cover 103 and a first fixing member 104. The first bracket 101 has an L-shaped structure. The first motor cable clamp 102 is provided with three through holes, the diameter of which is the same as the outer diameter of the cable 3. The first bracket 101 is also provided with through holes for fixing the grounding wire.

[0043] Specifically, the structure of the first support assembly 1 can be referred to in the appendix. Figure 3 With appendix Figure 4 The first bracket 101 is an L-shaped sheet structure. One end of the first bracket 101 is provided with two through holes, which are arranged vertically. The first bracket 101 is installed on the slide beam 2 through the through holes and the screws, washers, nuts and other structures. The other end of the first bracket 101 should be arranged as horizontally as possible. A third through hole is provided on the second end of the first bracket 101. This through hole can fix the grounding wire and also provides a space for the grounding wire to run and fix across the suspension frame. The first motor cable clamp 102 is provided with three through holes for the cable 3 to pass through and realize the positioning and wiring of the cable 3.

[0044] Based on the above embodiment, the first motor cable clamp 102 includes two clamping blocks arranged symmetrically. The surfaces of the two clamping blocks facing each other are provided with arc-shaped grooves. The two grooves are used to form a circular hole. The two clamping blocks are detachably connected to the first fixing member 104 through the first bracket cover plate 103.

[0045] Specifically, the first motor cable clamp 102 includes two clamping blocks. The cross-section of the two arc-shaped grooves of the two clamping blocks is semi-circular. When the two clamping blocks are joined together, they can form a cylindrical through hole. Grooves and mounting holes are provided at intervals on the clamping blocks. The mounting holes can pass through the clamping blocks. During installation, the two clamping blocks hold the three cables 3. The two clamping blocks are fixed to the first bracket 101 by the first fixing member 104. In addition, a first bracket cover plate 103 is provided on the side of the first motor cable clamp 102 away from the first bracket 101. The first bracket cover plate 103 can cooperate with the first fixing member 104 to improve the clamping degree of the first motor cable clamp 102.

[0046] Based on the above embodiment, the first fixing member 104 includes two screws, two nuts and two washers. The screws pass through the first motor cable clamp 102, and the two screws and the groove are alternately arranged.

[0047] Specifically, the first fastener 104 uses screws, nuts and washers, which are low-cost and can be mass-produced. The installation difficulty is also relatively low. Multiple screws can be tightened to the same degree by means of an electric torque wrench to ensure structural reliability. The size of the mounting hole on the first motor cable clamp 102 should be set according to the size of the screw. Its diameter should be larger than the screw diameter and smaller than the diameter of the screw head.

[0048] Based on the above embodiment, the first bracket 101 is provided with a strip-shaped through groove, the screw is provided through the through groove, and the nut is provided on the side of the first bracket 101 away from the large end of the screw.

[0049] Specifically, the second end of the first bracket 101 is provided with a strip-shaped through groove. Nuts and screws are respectively installed on both sides of the first bracket 101. The length of the through groove should be close to the length of the line connecting the centers of the holes on both sides of the first motor cable clamp 102. The through groove can adjust the position of the first motor cable clamp 102 on the first bracket 101 and prevent the cable 3 from being pulled when the cable 3 is laid.

[0050] Based on the above embodiments, the through-hole cross-sectional area of ​​the first motor cable clamp 102 includes at least two dimensions.

[0051] Specifically, cable 3 can be selected according to the speed level of the maglev car, and generally it is mainly 70mm. 2 and 95mm 2 There are two sizes, therefore the corresponding first motor cable clamp 102 should have a size of at least 70mm. 2 and 95mm 2 There are two models. In addition, it should be clarified that the first motor cable clamp 102 and the second motor cable clamp 402 have the same structure, and the first fixing member 104 and the second fixing member 404 also have the same structure.

[0052] Based on the above embodiments, the second support assembly 4 includes a second support 401, a second motor cable clamp 402, a second support cover plate 403 and a second fixing member 404. The second support 401 has a U-shaped structure. Two through holes are provided on one side of the second support 401 that is connected to the suspension frame longitudinal beam 5, and one through hole for fixing the suspension cable is provided on the other side of the second support 401.

[0053] Specifically, since the first support assembly 1 and the second support assembly 4 are respectively installed on the slide beam 2 and the suspension frame longitudinal beam 5, the first support assembly 1 is installed on the side wall of the slide beam 2, while the second support assembly 4 is installed on the side wall of the suspension frame longitudinal beam 5. The difference is that the first side of the second support 401 has two horizontally arranged through holes, which are installed by the second fastener 404. The second side of the second support 401 has only one through hole, which also has a tubular mounting part, through which the suspension cable can be fixed.

[0054] Based on the above embodiment, the second bracket 401 is a stainless steel component, and the thickness of the second bracket 401 is 4mm.

[0055] Specifically, both the first support 101 and the second support 401 are stainless steel components, which can prevent rust to a certain extent and extend their service life. The thickness of the second support 401 is generally 4mm to ensure structural strength. In addition, the suspension frame of the maglev train is usually made of aluminum alloy, such as 60082 aluminum alloy. Aluminum alloy has good corrosion resistance, and is also lightweight and strong, which can meet the operating requirements of the train.

[0056] Optionally, anodizing treatment can be performed on the surfaces of the first support 101 and the second support 401 to form a dense oxide film, which enhances their corrosion resistance and extends the service life of the equipment.

[0057] In summary, the wiring device spanning the suspension frame provided in this application has the following advantages:

[0058] (1) It can realize the fixation of the three-phase cable of the traction linear motor across the suspension frame;

[0059] (2) It can realize the fixing of the grounding cable across the suspension frame;

[0060] (3) It can realize the fixation of the suspended electromagnet cable on the suspension frame. The fixing direction of the electromagnet wire is perpendicular to the motor wire, which meets the vertical fixing requirements of cables of different voltage levels.

[0061] (4) This method can effectively solve the problem of dynamic cable length, and the length of the cable harness spanning the suspension frame is 1990mm;

[0062] (5) This fixing method is suitable for medium and low speed maglev vehicles;

[0063] (6) This wiring fixing method ensures the aesthetics of the wiring on the suspension frame, and the cables do not come into contact with each other or with the suspension frame, thus avoiding cable friction.
