Description

Technical Field

[0001] This invention relates to the field of track fixing technology, specifically to a magnetic fastener and a magnetic locking track frame. Background Technology

[0002] In high-speed railway construction, ballastless sleepers replace the wooden sleepers used in ordinary trains. Ballastless sleepers need to be evenly arranged on a foundation track bed made of materials such as concrete and asphalt mixture, and then permanently fixed by pouring concrete. To ensure that the sleepers are accurately positioned and arranged at the design intervals in the prefabrication site, and to facilitate subsequent transportation to the site for laying, a track panel frame is usually used to connect two track components into an integral structural component, so that the sleepers are suspended and fixed on it to form an assembly that can be transported as a whole.

[0003] Currently, the rail panels used both domestically and internationally are all constructed by connecting rail components with other steel structures using a fixed method. To secure these other steel components, holes must be drilled in the rail components. This structure results in a complex rail panel composition, makes it impossible to adjust the sleeper spacing, and hinders alignment adjustments during construction, increasing construction costs and operational difficulty. Summary of the Invention

The rotating assembly drives the second magnetic component to rotate, thereby changing the magnetic pole position relationship between the second magnetic component and the first magnetic component. When the same magnetic poles of the second magnetic component and the first magnetic component are on the same side, the magnetic lines of force pass through the track component to form a closed loop, so that the magnetic attraction fixing component is in a state of attracting weight. When the same magnetic poles of the second magnetic component and the first magnetic component are on opposite sides, the magnetic lines of force form a short-circuit loop inside, so that the magnetic attraction fixing component is in a state of unloading weight.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0020] According to an embodiment of the present invention, in a first aspect, a magnetic fastener is provided, adapted to be detachably attached to the side of a track member 1, comprising: The magnetic yoke 2 is adapted to be detachably fitted to the side of the track 1, and has an internal accommodating space. The first magnetic component 3 is fixedly disposed on the side of the accommodating space away from the track component 1, and the internal magnetic pole connection line of the first magnetic component 3 is arranged parallel to the length direction of the track component 1. The second magnetic component 4 is rotatably disposed on the side of the accommodating space close to the track component 1 and is arranged parallel to the first magnetic component 3. The internal magnetic pole connection line of the second magnetic component 4 is arranged parallel to the length direction of the track component 1. The rotating assembly is connected to the second magnetic element 4. The rotating assembly is used to drive the second magnetic element 4 to rotate, so as to change the magnetic pole position relationship between the second magnetic element 4 and the first magnetic element 3. When the same magnetic poles of the second magnetic element 4 and the first magnetic element 3 are on the same side, the magnetic lines of force pass through the track 1 to form a closed loop, so that the magnetic attraction fixing part is in the state of attracting weight; when the same magnetic poles of the second magnetic element 4 and the first magnetic element 3 are on opposite sides, the magnetic lines of force form a short circuit loop inside, so that the magnetic attraction fixing part is in the state of unloading weight.

[0021] Specifically, the magnetic fastener consists of a magnetic yoke 2, a first magnetic component 3, a second magnetic component 4, and a rotating assembly. The magnetic yoke 2 is located on the side of the track component 1 and has a built-in receiving space. The first magnetic component 3 is fixed in the receiving space on the side away from the track component 1, and the second magnetic component 4 is rotatably located on the side close to the track component 1. The two are parallel to each other and the magnetic pole lines are arranged along the length of the track component 1. The rotating assembly is connected to the second magnetic component 4. By driving the second magnetic component 4 to rotate, the relative position of its magnetic poles with the first magnetic component 3 is changed, thereby controlling the conduction path of the magnetic circuit and realizing the switching between the two working states of adsorption and locking and unlocking and unloading.

[0022] By setting a fixed first magnetic element 3 and a rotatable second magnetic element 4 inside the magnetic fastener, and arranging the lines connecting their magnetic poles parallel to the length direction of the track element 1, the rotation component drives the second magnetic element 4 to rotate, changing its relative position to the magnetic poles of the first magnetic element 3, thus achieving magnetic circuit switching. When the two magnetic poles of the same polarity are on the same side, the magnetic lines of force pass outward through the track element 1 and form a closed adsorption circuit with the magnetic yoke 2, so that the magnetic fastener is reliably locked onto the track element 1; when the two magnetic poles of the same polarity are on opposite sides, the magnetic lines of force form a short circuit inside the magnetic yoke 2, and no adsorption force is generated externally, thereby achieving rapid disengagement from the track element 1, thus completing the reliable switching between the locked and unlocked states.

[0023] In simple terms, the magnetic fastener uses a dual magnetic component with a rotating reversing structure, eliminating the need for mechanical fastening methods such as bolts and welding, and also eliminating the need to drill holes in the track component 1. This protects the structural integrity of the track component 1 and achieves damage-free and rapid assembly and disassembly. Locking and unlocking can be completed by switching the magnetic pole position, making the operation simple and reliable. The locking force is stable and uniform, and stepless positioning can be achieved at any position along the track component 1, meeting the need for flexible adjustment of sleeper spacing and improving the accuracy of track panel assembly and construction efficiency.

[0024] The magnetic fastener provided by this invention, by adopting a magnetic structure with switchable magnetic states, can achieve detachable and close-fitting fixation with the track component 1 without drilling holes in the track component 1, simplifying the overall structure of the track frame; at the same time, it can achieve flexible assembly and position adjustment by relying on magnetic adsorption, so that the sleeper spacing can be freely adjusted according to construction needs, making on-site alignment and laying more convenient, effectively reducing construction costs and operation difficulty, and solving the problems of complex structure, non-adjustable spacing, and inconvenient adjustment of traditional track frame.

[0025] Furthermore, the rotating assembly includes: Rotating action 51, one end of which is fixedly connected to the second magnetic component 4, and the other end extends to the outside of the magnetic yoke 2. By driving the rotating action 51 to rotate, the second magnetic component 4 is driven to rotate, so as to realize the switching of the magnetic attraction fixing component between the weight-attracting state and the weight-unloading state. The elastic element 52 and the magnetic yoke 2 are provided with mounting holes, and the elastic element 52 is disposed in the mounting holes; The stop pin 53 is movably disposed in the mounting hole. One end of the stop pin 53 abuts against the elastic member 52, and the other end is adapted to extend out of the mounting hole and abut against the rotating member 51.

[0026] Specifically, the rotating actuating component 51 can be a manual knob, a rotating handle, or a hexagonal rotating head structure. One end extends into the magnetic yoke 2 and is fixedly connected to the second magnetic component 4, while the other end protrudes outside the magnetic fixing component. By rotating the exposed end, the operator can directly drive the second magnetic component 4 to rotate synchronously, changing its relative position with the magnetic poles of the first magnetic component 3, thereby switching between the locking and unlocking states of the magnetic fixing component. The operation is intuitive and easy to implement. In this embodiment, the rotating actuating component 51 is a rotating handle.

[0027] It is easy to understand that the rotating actuating element 51 directly drives the second magnetic element 4 to rotate. The structure is simple and compact, and the transmission is direct and efficient. There is no need for complex transmission components such as gears and connecting rods, which effectively reduces the overall volume and weight of the magnetic fixing component. The weight-attracting and weight-unloading states can be quickly switched by rotating the operation. The operation is labor-saving and convenient, and it is easy for a single person to carry out the operation on site. At the same time, the rotation positioning is reliable and it is not easy to switch erroneously, which improves the construction safety and efficiency of the installation, adjustment and disassembly of the rail frame.

[0028] Specifically, the elastic element 52 is assembled in the mounting hole of the magnetic yoke 2, with one end abutting the bottom of the mounting hole and the other end abutting against the stop pin 53. It can continuously provide the stop pin 53 with an elastic pushing force toward the rotating actuating element 51, so that the stop pin 53 always maintains a working state of close contact with the rotating actuating element 51. After the rotating actuating element 51 rotates into place, it automatically tightens and positions itself by means of elastic force. The stop pin 53 is movably assembled in the mounting hole of the magnetic yoke 2. Under the pushing action of the elastic element 52, its protruding end abuts tightly against the rotating actuating element 51. Through the cooperation with the rotating actuating element 51, a limiting structure is formed to constrain and position the rotation angle of the rotating actuating element 51, and precisely limit the rotation position of the second magnetic element 4 in the two working states of attracting and unloading weight.

[0029] In a straightforward manner, the elastic element 52 ensures that the stop pin 53 forms a stable and reliable elastic clamping on the rotating element 51, preventing the rotating element 51 from loosening or the second magnetic element 4 from unexpectedly deflecting during construction vibrations or handling. At the same time, it can reliably maintain the rotation position without the need for an additional locking structure, thereby improving the stability and safety of switching magnetic states.

[0030] It is easy to understand that the stop pin 53 can accurately limit the rotation of the rotating part 51 and the second magnetic part 4, ensuring that each rotation switch is in place without over-rotation or deviation, ensuring that the switching between the magnetic attraction and unloading states of the magnetic fastener is accurate and reliable. At the same time, it relies on the abutment limit to prevent loosening and shaking, adapting to the complex working environment in the construction of the rail frame, and improving the durability and operational accuracy of the overall structure.

[0031] Of course, in an alternative embodiment, the limiting structure of the elastic element 52 and the stop pin 53 can be eliminated and replaced with an indexing rotary positioning assembly. Specifically, positioning grooves corresponding to the two states of attracting and unloading can be provided on the rotating actuating element 51, and an elastic positioning bead structure composed of a ball and a compression spring can be provided at the corresponding position of the magnetic yoke 2. Rotational positioning is achieved by the engagement and cooperation of the elastic positioning bead with different grooves; at the same time, the rotating actuating element 51 and the second magnetic element 4 can be connected by a damping shaft, and the rotation angle is maintained by the damping force. This embodiment eliminates the assembly and alignment steps of the stop pin 53, the structure is simpler, the rotation operation feels more uniform, the positioning response is more direct, and it can also effectively prevent the second magnetic element 4 from being accidentally deflected due to construction vibration, further improving the assembly efficiency and reliability of the magnetic fastener.

[0032] Furthermore, the rotating assembly also includes: Push rod 54 is fixedly connected to stop pin 53. A groove is provided on the side wall of magnetic yoke 2. The length direction of the groove is parallel to the depth direction of the mounting hole. Part of push rod 54 is exposed outside the groove.

[0033] Specifically, a push rod 54 is fixedly connected to the stop pin 53, and a groove extending along the depth direction of the mounting hole is opened on the side wall of the magnetic yoke 2. The push rod 54 passes through the groove and is partially exposed outside the magnetic yoke 2. The push rod 54 can move back and forth along the length direction of the groove, driving the stop pin 53 to synchronously compress the elastic element 52 or reset under the action of the elastic element 52, thereby realizing the switching between the stop pin 53 and the rotating action element 51 in the state of contact limit and release limit.

[0034] It is easy to understand that the extension and retraction of the stop pin 53 can be manually controlled by the exposed push rod 54. When it is necessary to switch the magnetic attraction state, the limit can be quickly released, making the operation intuitive and convenient. The slide groove constrains the movement stroke of the push rod 54, which can ensure the accurate movement direction of the stop pin 53 and prevent the stop pin 53 from being excessively displaced or dislodged. At the same time, it does not increase the overall volume and does not affect the fit and installation of the magnetic attraction fastener and the track component 1, thus improving the operational efficiency and ease of use of the state switching.

[0035] Furthermore, the magnetic yoke 2 includes: The magnetic yoke body 21 has an internal accommodating space. The axial direction of the accommodating space is parallel to the length direction of the track component 1. A second magnetic component 4 is rotatably disposed on the side of the accommodating space close to the track component 1, and a first magnetic component 3 is fixedly disposed on the side of the accommodating space away from the track component 1. The magnetic yoke fixing part 22 is disposed on the magnetic yoke body part 21 and located on both sides of the accommodating space away from the track member 1. The magnetic yoke fixing part 22 is adapted to restrict the movement of the first magnetic member 3 and the second magnetic member 4 along the length direction of the accommodating space.

[0036] Specifically, the magnetic yoke 2 is formed by the fixed connection of the magnetic yoke body 21 and the magnetic yoke fixing part 22. The magnetic yoke body 21 has a block structure, and its interior has a receiving space extending through the length of the track 1. The size of the receiving space is adapted to the shape of the first magnetic component 3 and the second magnetic component 4. The first magnetic component 3 is fixed in the receiving space of the magnetic yoke body 21 away from the track 1 by means of bonding, embedding or bolting. The second magnetic component 4 is assembled in the receiving space near the track 1 by bearings, bushings or other rotating means, so as to achieve flexible rotation in the receiving space. The magnetic yoke fixing part 22 is a symmetrical protrusion or baffle structure arranged on both sides of the through hole. It is formed synchronously with the magnetic yoke body 21. Its end face fits with the ends of the first magnetic component 3 and the second magnetic component 4 to achieve axial limit of the two along the length of the through hole and prevent them from being displaced.

[0037] Specifically, the magnetic yoke 2 is made of soft magnetic material with high permeability and high strength, preferably electrical pure iron, silicon steel sheet or permalloy. The main body 21 of the magnetic yoke can be integrally formed from electrical pure iron to ensure smooth transmission of magnetic lines of force, reduce magnetic loss and improve the adsorption strength of the magnetic fastener. The magnetic fastener 22 and the main body 21 of the magnetic yoke are made of the same material. If a split structure is adopted, it can be fixed by welding. The welding material is low carbon steel welding rod that matches the main body material to ensure connection strength and magnetic conduction performance, while taking into account the material processing technology and cost control.

[0038] In a straightforward manner, the accommodating space structure of the magnetic yoke body 21 provides a stable installation and rotation space for the first magnetic component 3 and the second magnetic component 4, ensuring that they always remain parallel and that the magnetic poles are aligned, thus guaranteeing the reliability of the magnetic circuit switching. The symmetrically arranged magnetic yoke fixing parts 22 on both sides can effectively restrict the axial movement of the first magnetic component 3 and the second magnetic component 4, preventing the magnetic components from becoming misaligned due to construction vibration or bumps during transportation, and ensuring the stability of the locking and unlocking functions of the magnetic fastener. The overall structure is compact and highly compatible with other components of the magnetic fastener.

[0039] Furthermore, both the first magnetic component 3 and the second magnetic component 4 are cuboids, and the accommodating space includes a first hole 211 and a second hole 212 that are interconnected. The first hole 211 is adapted to the first magnetic component 3 to fix it, and the second hole 212 is an arc-shaped hole with a diameter equal to the length of the diagonal of the cross section of the second magnetic component 4 perpendicular to the length direction of the track component 1.

[0040] Specifically, both the first magnetic component 3 and the second magnetic component 4 are set as cuboid structures. The accommodating space inside the magnetic yoke 2 is divided into a first hole 211 and a second hole 212 that are interconnected. The shape and size of the first hole 211 are adapted to the first magnetic component 3 to achieve tight fitting and fixation of the first magnetic component 3. The second hole 212 is an arc-shaped hole, and its diameter is equal to the length of the diagonal of the cross section of the second magnetic component 4 perpendicular to the length direction of the track component 1, so that the cuboid second magnetic component 4 can rotate smoothly in the arc-shaped hole, while ensuring uniform rotation gap.

[0041] It is easy to understand that the rectangular magnetic component is easy to process and magnetizes evenly, which is conducive to mass production and stable magnetic output. The first hole 211 and the first magnetic component 3 are precisely matched to prevent them from loosening and shifting. The arc-shaped hole provides sufficient rotation space for the second magnetic component 4 and minimizes the assembly gap, avoiding the magnetic component from shaking and shifting, ensuring reliable switching between the weight-attracting and weight-unloading states, while improving the utilization rate of the magnetic circuit and the overall structural compactness.

[0042] In an alternative embodiment, the first magnetic component 3 and the second magnetic component 4 can be replaced with cylindrical permanent magnets. Correspondingly, the first hole 211 of the accommodating space is set as a straight hole adapted to the cylindrical magnetic component, and fixed by interference fit or adhesive bonding. The second hole 212 is a circular through hole matching the outer diameter of the cylinder, allowing the second magnetic component 4 to rotate around its own axis. This method ensures higher processing accuracy, reduces rotational friction, lowers rotational resistance, and further improves the smoothness of operation and service life of the rotating assembly.

[0043] Furthermore, the inner side of the track component 1 is provided with a concave surface, and the magnetic fastener has a convex surface that matches the concave surface, with the convex surface conformally fitting the concave surface.

[0044] In simple terms, the conformal fit between the concave inner surface of track component 1 and the convex surface of the magnetic fastener increases the contact area between the two, making the magnetic fastener fit more tightly with track component 1. This not only improves the stability and firmness of the magnetic locking and reduces magnetic loss, ensuring uniform transmission of the adsorption force, but also provides radial limiting for the magnetic fastener, preventing it from shifting or sliding along the width of track component 1, thus ensuring the positional accuracy of the sleeper after suspension and fixation. At the same time, the conformal fit structure conforms to the shape of track component 1, avoiding local stress concentration, protecting the surface of track component 1 from wear, further improving the overall stability and service life of the track frame, and adapting to complex working conditions such as vibration and handling during high-speed railway construction.

[0045] Furthermore, both the first magnetic component 3 and the second magnetic component 4 are made of neodymium iron boron permanent magnet material.

[0046] It is easy to understand that both the first magnetic component 3 and the second magnetic component 4 are made of neodymium iron boron permanent magnet material, which has extremely high magnetic energy product and coercivity, and can generate a strong and stable magnetic field. This ensures that the magnetic fastener has sufficient adsorption force in the locked state, and can be firmly adsorbed onto the track component 1. It can effectively resist external force interference under construction vibration, track panel transportation and other working conditions, and avoid accidental unlocking. At the same time, the magnetic properties of this material are stable, the service life is long, and it is not easy to experience magnetic attenuation. It does not require frequent maintenance and replacement, reducing the cost of use. Moreover, its small size and light weight can effectively reduce the overall size and weight of the magnetic fastener, making it easy to assemble and construct, and meeting the construction needs of lightweight and efficient track panel frame construction.

[0047] According to an embodiment of the present invention, in a second aspect, a magnetic locking rail frame is also provided, comprising: Two track components 1 are arranged parallel to each other along their length direction, together forming a track; It also includes any of the above-mentioned magnetic fasteners, which are arranged in pairs, with the two magnetic fasteners in each pair respectively positioned opposite each other on the two track components 1.

[0048] Specifically, track component 1, as the main load-bearing component of the magnetic locking rail panel frame, consists of two long strip profiles arranged in parallel, extending along their length to form a regular track path, providing a stable support benchmark and installation reliance for the sleepers. The two track components 1 are parallel to each other and maintain the designed spacing, ensuring that the sleepers are in a horizontal and centered state during assembly. At the same time, they provide a flat and continuous side contact surface for the magnetic fasteners, allowing the magnetic fasteners to slide and be positioned freely along the length of track component 1, meeting the flexible arrangement requirements of different sleeper spacings.

[0049] Furthermore, it also includes a support fastener 6, which is adapted to fix the magnetic fastener to the ground.

[0050] In a straightforward manner, by setting up the support fixing component 6, the magnetic fixing component and the track component 1 can be firmly connected to the ground as a whole, effectively preventing the track panel frame from shifting, shaking, or floating during concrete pouring, vibration, and sleeper positioning, ensuring that the spacing and levelness of the track component 1 always meet the construction accuracy requirements; at the same time, in conjunction with the adjustable characteristics of the magnetic fixing component, it not only realizes the flexible adjustment of the track position, but also has a reliable overall fixing effect, improving the stability and positioning accuracy of the track panel erection construction.

[0051] Furthermore, the support fastener 6 includes: The support fixing part 61 is provided perpendicular to the track member 1, and the fixing part is at least partially placed in the ground; The connecting part 62 is fixedly connected to the support fixing part 61. The connecting part 62 has a first connecting section disposed at the bottom of the track member 1 and a second connecting section disposed between the two track members 1 and connected to the magnetic fixing member.

[0052] Specifically, the support and fixing part 61 is arranged perpendicular to the track component 1 and is at least partially buried in the ground to form a reliable ground anchoring foundation; the connecting part 62 is fixed to the support and fixing part 61 as a whole, and its first connecting section supports the bottom of the track component 1, which plays a supporting and limiting role for the track component 1; the second connecting section is located between the two track components 1 and is connected to the magnetic fixing component, connecting the magnetic fixing component, the track component 1 and the ground foundation into an integral structure.

[0053] In a straightforward manner, the support and fixing component 6 adopts a segmented connection structure, which can stably support the track component 1 from the bottom, ensuring its levelness and parallelism, and reliably connect the magnetic fixing component between the two track components 1, achieving dual locking of magnetic adsorption and ground fixation. This effectively resists external force disturbance during the pouring construction, prevents the track component 1 from shifting or floating, and at the same time, the layout is compact, does not occupy the space outside the track, and facilitates on-site construction operations.

[0054] In an alternative embodiment, the support fixing member 6 can be replaced with an integrated profile bending structure, which directly forms the support section, bottom support section and inner connecting section by bending the profile, eliminating the need for separate welding or assembly; the support fixing part 61 adopts an adjustable anchor bolt structure to achieve fine adjustment of height and level, and the connection between the connecting section and the magnetic fixing member is replaced with quick plug-in or snap-fit ​​connection, eliminating fasteners, making disassembly and assembly faster, with higher overall strength and easier control of installation accuracy.

[0055] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
