Description

Technical Field

[0001] This application relates to the field of rail power supply system technology, and in particular to a three-rail support with an adjustable protective cover position. Background Technology

[0002] Currently, most urban subways use a third rail power supply method, which involves laying an I-beam parallel to the two rails as a third rail (contact rail), and the subway car receives power from the third rail through a power receiving device.

[0003] The third rail is usually suspended in the air, and a support bracket is installed at regular intervals (e.g., 4.5 meters) to suspend and fix the third rail. To better protect the support brackets, protective covers need to be installed on them.

[0004] In existing technologies, protective covers are typically specialized, meaning a particular cover is only suitable for a specific type of three-rail support and lacks versatility for use with other three-rail supports. However, whether it's different sections of the same subway project or different subway projects, the horizontal distance between the three rails and the fixed support, or the vertical distance between the three rails and the ground, varies. Therefore, traditional protective covers are clearly not universal, requiring specific covers for each installation on a particular three-rail support, resulting in poor practicality. Thus, designing a three-rail support with a universal protective cover is particularly important. Utility Model Content

[0005] The main objective of this application is to provide a three-rail bracket with an adjustable protective cover position, which aims to solve the technical problem of poor versatility of the protective cover of existing three-rail brackets.

[0006] To achieve the above objectives, this application provides a three-rail bracket with an adjustable protective cover position, including an insulating fastener, an insulating support plate, and an insulating bracket. The insulating support plate is fixed to the insulating bracket, the insulating fastener is connected to the insulating support plate, and a rail groove for fixing the third rail is formed between the insulating fastener and the insulating support plate.

[0007] The three-rail support also includes a protective cover, which includes:

[0008] The mounting part is disposed on the insulating bracket, and the mounting part is provided with an adjustment part, which is used to guide the protective cover to achieve horizontal and vertical movement adjustment.

[0009] The cover portion is connected to the mounting portion and is located on one side of the insulating fastener and the insulating support plate, for covering the insulating fastener, the insulating support plate and the third rail.

[0010] Optionally, the mounting portion and the cover portion are integrally formed to create a T-shaped structure for the cover.

[0011] Optionally, the mounting portion includes a first side plate, a second side plate, and a first top plate. The first side plate and the second side plate are disposed on both sides of the first top plate to form a U-shape, so as to fasten to the top side of the insulating bracket.

[0012] Optionally, both the first side plate and the second side plate are provided with the adjustment part, the adjustment part comprising:

[0013] At least two first chutes arranged horizontally from top to bottom;

[0014] A second slide groove is set vertically, and the second slide groove is set at the midpoint of all the first slide grooves.

[0015] Optionally, the insulating bracket is provided with fasteners for securing the protective cover.

[0016] Optionally, the fastener includes:

[0017] A fastening bolt passing through the adjustment section and fixed to the insulating bracket passes through the first or second slide groove when the cover moves;

[0018] A gasket, wherein the gasket is fitted onto the fastening bolt and is in close contact with the first side plate and the second side plate;

[0019] A spring washer, which is sleeved on the fastening bolt and fits against the side of the washer away from the first side plate and the second side plate;

[0020] A locking nut, which is threaded onto the fastening bolt and presses against the washer and the spring washer.

[0021] Optionally, the cover includes a third side plate, a fourth side plate, and a second top plate. The third side plate and the fourth side plate are disposed on both sides of the second top plate to form a U-shape to cover the insulating fastener, the insulating support plate, and the third rail.

[0022] Optionally, the insulating tray includes:

[0023] A fixed crossbeam, one end of which is connected to the insulating bracket, and the other end of which is connected to the insulating fastener;

[0024] The first oblique side arm is integrally formed at the bottom of the fixed crossbeam and is inclined toward the insulating fastener side.

[0025] Optionally, the insulating fastener includes:

[0026] A connecting beam is fixedly connected to the fixed beam.

[0027] A vertical plate, which is integrally formed on the end of the connecting beam away from the fixed beam;

[0028] The second inclined side arm is integrally formed at the bottom end of the vertical plate and is inclined toward the first inclined side arm. The first inclined side arm, the connecting crossbeam, the fixing crossbeam, the vertical plate, and the second inclined side arm form the track groove.

[0029] Optionally, an insulating inner layer is provided on the inner side of the rail groove.

[0030] The beneficial effects that this application can achieve are as follows:

[0031] The protective cover in this application can be freely adjusted in multiple directions (up, down, left, and right) on the three-rail support, exhibiting extremely high adaptability. Therefore, the position of the protective cover can be selectively adjusted to adapt to the installation of the three-rail support according to the actual installation needs of the three-rail support in the project, effectively protecting the three-rail support and greatly improving its practicality.

[0043] Example

[0044] Reference Figures 1 to 3 As shown, this embodiment provides a three-rail support with adjustable protective cover position, including an insulating fastener 300, an insulating support plate 200, an insulating support 100, and a protective cover 400. Specifically: the insulating support plate 200 is fixed to the insulating support 100, the insulating fastener 300 is connected to the insulating support plate 200, and a rail groove for fixing the third rail 700 is formed between the insulating fastener 300 and the insulating support plate 200; the protective cover 400 includes a mounting part 401 and a cover part 402, wherein the mounting part 401 and the cover part 402 are integrally formed, the mounting part 401 is used to fix the protective cover 400 to the insulating support 100, the mounting part 401 is provided with an adjustment part, the adjustment part is used to guide the protective cover 400 to achieve horizontal and vertical movement adjustment, the cover part 402 is located on one side of the insulating fastener 300 and the insulating support plate 200, and the cover part 402 is used to cover the insulating fastener 300, the insulating support plate 200, and the third rail 700.

[0045] In this embodiment, since the cover 400 can move freely up, down, left, and right in both horizontal and vertical directions, the position of the cover 400 can be adjusted according to the horizontal distance between the third rail 700 and the insulating support 100 and the vertical height of the third rail 700 from the vertical direction. This makes the cover 400 versatile and able to cover the third rail 700 under different usage requirements, thereby improving the practicality of the cover 400.

[0046] In this embodiment, the insulating bracket 100 is used to fix itself to the track foundation and serves to support the insulating support plate 200 and the insulating fastener 300. To achieve this purpose of the insulating bracket 100, see [link to documentation]. Figures 1 to 3As shown, the insulating support 100 includes a frame 102, with a base 101 integrally formed at the bottom of the frame 102. Mounting screws are provided on the base 101, which are used to fix the insulating support 100 to the rail foundation. To prevent the entire trirail support from becoming energized, the insulating support 100 is grounded. Multiple mounting wing plates 103 are integrally formed on the top of the insulating support 100. Mounting screw holes are provided on the mounting wing plates 103, and the insulating support plate 200 is fixed to the mounting wing plates 103.

[0047] In this embodiment, in order for the protective cover 400 to be mounted on the insulating bracket 100 via the mounting part 401 and to ensure that the protective cover 400 can move freely, see [reference needed]. Figures 1 to 2 As shown, the mounting part 401 includes a first side plate 4010, a second side plate 4011, and a first top plate 4012. The first side plate 4010 and the second side plate 4011 are integrally formed on opposite sides of the first top plate 4012 to form a U-shape, thereby allowing the mounting part 401 to be fastened to the top side of the insulating bracket 100. Simultaneously, an adjustment part is provided on both the first side plate 4010 and the second side plate 4011. Specifically, the adjustment part includes a first slide groove 500 and a second slide groove 501. The first slide groove 500 includes at least two sections, and the first slide grooves 500 are horizontally arranged from top to bottom on the first side plate 4010 and the second side plate 4011. The second slide groove 501 is vertically arranged and is disposed at the midpoint of all the first slide grooves 500, so that all the first slide grooves 500 communicate with the second slide groove 501. In order to secure the mounting part 401 to the insulating bracket 100 after the position is adjusted, in this embodiment, the insulating bracket 100 is provided with fasteners for securing the protective cover 400. Specifically, see [link to documentation]. Figures 1 to 2As shown, the fasteners include a fastening bolt 600, a washer 601, a spring washer 602, and a locking nut 603. The fastening bolt 600 is disposed in the mounting screw hole of the mounting wing plate 103, and the fastening bolt 600 passes through the mounting screw hole from the inner side of the mounting wing plate 103 to the outer side of the mounting wing plate 103, and passes through the first slide groove 500 or the second slide groove 501 where the adjustment part is located. The washer 601, the spring washer 602, and the locking nut 603 are sequentially sleeved on the fastening bolt 600 on one side of the mounting part 401, and the locking nut 603 presses the cover 400 onto the insulating bracket 100. Predictably, loosening the locking nut 603 allows the protective cover 400 to move. Then, based on the location of the third rail 700 on site, the protective cover 400 is moved up, down, left, and right to ensure it always covers the protected structural component. After adjustment, the locking nut 603 is tightened to secure the protective cover 400 to the insulating bracket 100 and prevent it from falling off. It is important to note that during the adjustment of the protective cover 400's movement, the first slide rail 500 and the second slide rail 501 can avoid the fastening bolt 600, allowing the bolt 600 to pass freely through the first slide rail 500 and the second slide rail 501 without obstruction, ensuring the protective cover 400 can move freely and without restriction.

[0048] In this embodiment, in order to fix the third track 700, see [reference needed]. Figure 3 As shown, the insulating support plate 200 includes a fixed crossbeam 201 and a first inclined side arm 202. One end of the fixed crossbeam 201 has an integrally formed connecting end plate, which is fixed to the top side of the insulating bracket 100 by screws. The other end of the fixed crossbeam 201 has a threaded connection hole on its top side for fixed connection with the insulating fastener 300 by screws. The first inclined side arm is integrally formed at the bottom of the fixed crossbeam 201 and is inclined towards the insulating fastener 300.

[0049] In order to achieve connection with the insulating tray 200, in this embodiment, see... Figure 3As shown, the insulating fastener 300 includes a connecting beam 301, a vertical plate 302, and a second inclined side arm 303. The connecting beam 301 has a right-angled contact portion 304 at one end near the fixed beam 201. When the insulating support plate 200 is connected to the insulating fastener 300, the fixed beam 201 abuts against the vertical direct contact surface of the contact portion 304, while the horizontal contact surface of the contact portion 304 is attached to the upper surface of the fixed beam 201. The connecting beam 301 and the fixed beam 201 are fastened together by screws. Meanwhile, the vertical plate 302 is integrally formed on the end of the connecting beam 301 away from the fixed beam 201, and the second inclined side arm 303 is integrally formed on the bottom end of the vertical plate 302 and is inclined towards the first inclined side arm 202. Thus, the first inclined side arm 202, the connecting beam 301, the fixed beam 201, the vertical plate 302 and the second inclined side arm 303 form a rail groove, and the third rail 700 is fixed in the rail groove.

[0050] In one embodiment, to make the connection between the insulating tray 200 and the insulating fastener 300 more secure and stable, see [reference needed]. Figure 3 As shown, a shoulder 305 is provided at the joint 304 position of the connecting crossbeam 301. A T-shaped groove is provided at the bottom of the shoulder 305. Correspondingly, a T-shaped block 203 is provided at the position of the fixed crossbeam 201 corresponding to the shoulder 305. The T-shaped block 203 is engaged in the T-shaped groove, thereby further securing the insulating support plate 200 and the insulating fastener 300.

[0051] In one embodiment, to increase the insulation of the rail groove, see [reference needed]. Figure 3 As shown, an insulating inner layer 306 is provided inside the rail groove. It can be understood that the insulating fastener 300, insulating support plate 200 and insulating bracket 100 are all made of composite materials, and the insulating inner layer is made of insulating material to ensure that the three-rail support meets the usage requirements.

[0052] In this embodiment, to ensure that the protective cover 400 can cover the insulating fastener 300, the insulating support plate 200, and the third rail 700, see [reference needed]. Figures 1 to 2 As shown, the cover portion 402 includes a third side plate 4020, a fourth side plate 4021, and a second top plate 4022. The third side plate 4020 and the fourth side plate 4021 are integrally formed on both sides of the second top plate 4022 to form a U-shape, so as to cover the insulating fastener 300, the insulating support plate 200, and the third rail 700. The second top plate 4022 is aligned with the direction of the third rail 700. Thus, after the mounting portion 401 and the cover portion 402 are integrally formed, a T-shaped protective cover 400 is formed, which can better protect the three-rail support.

[0053] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
