Abstract
Description
Technical Field
[0001] This invention relates to the field of railway iron removal equipment technology, specifically to an electromagnetic iron removal vehicle and iron removal method. Background Technology
[0002] When railway vehicles arrive at loading stations for maintenance, workers need to reinforce or tighten any loose metal parts in the vehicles. This involves binding them with wire, and then cutting off any excess wire, which may fall onto the railway tracks. The wire is quite sharp, posing a safety hazard to other workers.
[0003] Current methods for removing iron wire typically involve manually removing the severed wires, which is labor-intensive and inefficient. Furthermore, iron wires may remain in hard-to-reach areas such as crevices in the ballast, resulting in poor cleaning effectiveness. Summary of the Invention

[0018] Optionally, the swing arm mechanism is provided with a self-locking slider that is slidably connected to the lifting slide in a vertical direction.
[0019] Optionally, the bottom of the vehicle body has multiple rubber wheels.
[0020] Optionally, a push-pull rod is provided on the end face of the vehicle body opposite to the swing arm mechanism.
[0021] Optionally, the battery box contains a built-in battery; a power switch is also provided on the end face of the vehicle body opposite to the swing arm mechanism;
[0022] The battery is electrically connected to the electromagnet, the swing arm mechanism, and the power switch.
[0023] Furthermore, the present invention also provides an iron removal method for an electromagnetic iron removal vehicle, wherein the iron removal method is implemented based on the electromagnetic iron removal vehicle described above, and the iron removal method includes:
[0024] Move the electromagnetic iron removal vehicle, which is currently in its original position, to the working position;
[0025] The electromagnet is energized; when energized, the electromagnet attracts magnetic materials; simultaneously, the magnetic field generated by the electromagnet drives the vehicle body to move.
[0026] The swing arm mechanism drives the electromagnet to flip above the collection port; in the unloading state, the electromagnet is de-energized, the vehicle body stops moving, and the magnetic material falls naturally into the collection box.
[0027] After unloading is completed, the electromagnet is reset to its original position and then energized to perform the operation again.
[0028] (III) Beneficial Effects
[0029] The beneficial effects of this invention are:
[0030] The swing arm mechanism can adjust the position of the electromagnet, enabling it to attract magnetic materials on the railway from multiple directions. This meets the cleaning needs of magnetic materials in blind spots and unseen locations, eliminating safety hazards. Compared to manual material cleaning, the electromagnetic iron removal vehicle can operate automatically, significantly reducing labor intensity and improving cleaning efficiency and effectiveness.
[0031] The swing arm mechanism can also flip the electromagnet above the collection port. After the electromagnet is de-energized, the material adsorbed on the electromagnet will naturally fall into the collection box through the collection port for recycling and storage. Then the electromagnet can resume normal operation, enabling the electromagnetic iron removal vehicle to meet the cleaning needs of large volumes of magnetic materials and improve cleaning efficiency.
[0032] When an electromagnet is energized, it generates a magnetic field. By setting a magnetic component on the collection box, the magnetic field can act on the magnetic component, providing a traction force to drive the vehicle to move. This significantly reduces the labor intensity of manually pushing and pulling the electromagnetic iron removal vehicle and improves work efficiency. Attached Figure Description

[0041] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0042] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0043] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0044] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; "connection" can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0045] See Figures 1 to 6 This invention provides an electromagnetic iron removal vehicle, comprising a vehicle body 1, a swing arm mechanism, an electromagnet 10, a collection box 2, and a battery box 3. The collection box 2 and the battery box 3 are respectively disposed on the vehicle body 1. The top of the collection box 2 has a collection port. The battery box 3 is electrically connected to the swing arm mechanism and the electromagnet 10. One end of the swing arm mechanism is connected to the vehicle body 1, and the other end is connected to the electromagnet 10. The swing arm mechanism can drive the electromagnet 10 to rotate above the collection port. The collection box 2 is provided with a magnetic component so that the electromagnet 10 can attract the magnetic component when energized, thereby moving the vehicle body 1. The electromagnetic iron removal vehicle can be operated remotely via signal control or manually via a control panel on the vehicle body 1.
[0046] The vehicle body 1 is mobile and easy to move. The swing arm mechanism can adjust the position of the electromagnet 10, enabling the electromagnet 10 to attract magnetic materials on the railway from multiple directions, meeting the cleaning needs of magnetic materials in dead corners and invisible locations, and eliminating safety hazards. Compared with manual cleaning, the electromagnetic iron removal vehicle can operate automatically, greatly reducing the intensity of manual labor and improving cleaning efficiency and effect.
[0047] In one embodiment, the electromagnet 10 is a composite electromagnetic system composed of neodymium iron boron (NdFeB) rare-earth permanent magnet material with high magnetic permeability and low remanence, and a high-purity copper coil. The coil uses insulated enameled wire and is sealed with heat-resistant silicone to improve reliability and durability in outdoor dusty and humid environments. The electromagnetic induction coil is designed with a multi-level current adjustment module, which precisely controls the magnetic force by changing the current. For example, the high level is used to attract heavy or deeply embedded iron objects, the low level is used for light iron filings, and the energy-saving level is used to maintain traction but not to attract materials temporarily.
[0048] The swing arm mechanism can also flip the electromagnet 10 above the collection port. After the electromagnet 10 is de-energized, the material adsorbed on the electromagnet 10 naturally falls into the collection box 2 for recycling and storage through the collection port. Then the electromagnet 10 can resume normal operation, enabling the electromagnetic iron removal vehicle to meet the cleaning needs of large volumes of magnetic materials and improving cleaning efficiency. The battery box 3 supplies power to the relevant electrical equipment of the electromagnetic iron removal vehicle.
[0049] The swing arm mechanism can be equipped with a waterproof and dustproof servo motor or hollow hydraulic cylinder as the pitch drive power, and integrates a high-precision angle sensor and torque limiter. The torque limiter can prevent excessive load on the swing arm from causing structural damage; the angle sensor is linked with the controller to realize one-click memory and automatic reset function of the electromagnet's working posture, which greatly simplifies the operation complexity.
[0050] When the electromagnet 10 is energized, it generates a magnetic field. By setting a magnetic component on the collection box 2, the magnetic field can act on the magnetic component, providing a traction force to drive the vehicle body 1 to move. This greatly reduces the labor intensity of manually pushing and pulling the electromagnetic iron removal vehicle and improves the work efficiency.
[0051] This invention utilizes the magnetic principle of electromagnets, employing a battery, coil, and electromagnet 10 to construct an electromagnetic iron removal vehicle. When energized, the electromagnet 10 has an adsorption function, propelling the vehicle body 1 and attracting impurities (magnetic materials) such as iron wire and iron shavings. These magnetic materials, after the electromagnet 10 is de-energized by flipping, fall naturally into the collection box 2, completing the iron removal function. The electromagnet 10 has a tilting function; its height relative to the ground can be adjusted according to the wiring conditions to achieve a specific adsorption effect.
[0052] In one embodiment, the magnetic component is built into the collection box 2. Specifically, by building the magnetic component into the collection box 2, magnetic materials are prevented from adhering to the surface of the magnetic component during operation, reducing the difficulty of cleaning up the magnetic materials later. At the same time, the magnetic component can cooperate with the magnetic field generated by the electromagnet 10 to drive the vehicle body 1 to move. No manual intervention is required during the driving process, or it can assist manual pushing of the vehicle body 1, reducing the intensity of manual labor.
[0053] In another embodiment, the collection box 2 and / or the battery box 3 are magnetic boxes. In this embodiment, both the collection box 2 and the battery box 3 are made of 3mm thick iron plate welded together, which can also cooperate with the magnetic field generated by the electromagnet 10 to drive the vehicle body 1 to move. No manual intervention is required during the driving process, or it can assist manual pushing of the vehicle body 1, reducing the intensity of manual labor.
[0054] Optionally, the main body of the collection box 1 can be made of carbon steel, and one or more high-performance permanent magnets can be reasonably arranged on its inner wall or bottom as "magnetic components". This allows it to generate a strong attraction with the magnetic field of the electromagnet 10 to drive the vehicle body, and also to further gather and fix the loose iron filings adsorbed into the collection box 1 during unloading, preventing secondary scattering. The collection box 1 can adopt a front-to-back (or left-to-right) sliding cover design, which can be quickly operated by one person during emptying. A removable high-strength nylon screen or buffer pad can be added below the collection port to withstand the impact of falling heavy objects and filter some of the slag and dust.
[0055] Furthermore, the swing arm mechanism includes a front swing arm 9, a joint bearing 11, and a rear swing arm 8; one end of the rear swing arm 8 is hinged to the vehicle body 1, and the other end is connected to the joint bearing 11; one end of the front swing arm 9 is connected to the joint bearing 11, and the other end is connected to the electromagnet 10. Specifically, the front swing arm 9 can rotate around the axis of the joint bearing 11, thereby pitching relative to the rear swing arm 8. Through the coordinated operation of the front and rear swing arms, the electromagnet 10 can pitch vertically, thereby achieving magnetic cleaning at a lower height and unloading at a higher height. The electromagnet 10 switches between working and unloading postures by rotating, resulting in a simple, practical, and easily accessible structure.
[0056] Optionally, the front and rear swing arms are made of manganese steel plate (10mm thick). The connection between the front swing arm 9 and the electromagnet 10 is insulated to prevent magnetic materials from adhering to the front swing arm 9 and reduce the difficulty of cleaning the equipment itself.
[0057] Optionally, the width of the electromagnet 10 is adapted to the width of the working surface. In this embodiment, the width of the electromagnet 10 is adapted to the width of the railway, and the car body 1 travels on the inner side of the railway, enabling it to attract magnetic materials on the inner side of the railway. The car body can also travel on the outer side of the railway, enabling it to attract magnetic materials on both sides of the railway.
[0058] Optionally, the swing arm mechanism also includes a slewing base (not shown); the slewing base is mounted on the vehicle body 1; the rear swing arm 8 is mounted on the slewing base, and the slewing base can drive the rear swing arm 8 to swing axially in the joint bearing 11, so that the electromagnet 10 can swing axially in the joint bearing 11. For example, when the vehicle body 1 travels outside the railway, the swing arm mechanism can move the electromagnet 10 from the outside of the railway to the inside of the railway, and then adjust the working height of the electromagnet 10 vertically, finally moving the electromagnet 10 to a suitable working position. The slewing base improves the flexibility of the electromagnetic iron removal vehicle in different working conditions, improves the stability of the vehicle body 1 when traveling outside the railway, facilitates manual follow-up operations, and enhances safety.
[0059] The slewing base can be driven by a worm gear reducer motor, whose self-locking characteristics ensure the stability of the horizontal swing position and enable the electromagnet to be continuously or fixedly positioned on the inner and outer sides of the track. To ensure structural strength and corrosion resistance, all swing arm components and lifting slides 7 can be made of high-strength aluminum alloy profiles welded frames with hard anodizing treatment on the surface.
[0060] Secondly, the electromagnetic iron removal vehicle also includes a lifting slide 7 mounted on the vehicle body 1 and facing the electromagnet 10 in its original position; the swing arm mechanism is vertically slidably connected to the lifting slide 7. Specifically, Figure 1 and Figure 2 The posture shown is the in-situ state of electromagnet 10. In this state, the height of electromagnet 10 is moderate, preventing collision with ground materials while also avoiding the safety hazard of materials falling due to excessive height. The swing arm mechanism can slide vertically on the lifting slide 7, further improving the flexibility of the electromagnetic iron removal vehicle and enhancing the vertical accessibility of electromagnet 10.
[0061] Optionally, the swing arm mechanism is provided with a self-locking slider 12 that slides vertically connected to the lifting slide 7. The self-locking slider 12 and the lifting slide 7 form a slider rail structure, and the self-locking slider 12 has a self-locking function. The self-locking slider 12 can be selected from an existing mechanical locking structure composed of wedges and springs or a friction pressing structure, which effectively ensures the connection stability of the self-locking slider 12 when it stops lifting, thereby ensuring the stability of the working position of the electromagnet 10.
[0062] In addition, the bottom of the vehicle body 1 has multiple rubber wheels 6. In this embodiment, rubber wheels 6 are provided at the four corners of the bottom of the vehicle body 1. The rubber wheels 6 effectively isolate the magnetic field generated by the electromagnet 10, effectively preventing magnetic materials from adhering to the rubber wheels 6, and ensuring the stability and safety of the vehicle body 1 during movement.
[0063] Furthermore, a push-pull rod 5 is provided on the end face of the vehicle body 1 away from the swing arm mechanism. A person can hold the push-pull rod 5 to move the vehicle body 1, and the magnetic field pulls the vehicle body 1 together to drive the vehicle body 1 to move, which effectively reduces the labor intensity of manual labor and can more flexibly deal with situations such as the steering of the vehicle body 1 and the rubber wheels 6 getting stuck in the gaps of the ballast stone, ensuring the smooth progress of the cleaning operation.
[0064] Secondly, the battery box 3 houses a storage battery 13; a power switch 4 is also provided on the end face of the vehicle body 1 facing away from the swing arm mechanism; the storage battery 13 is electrically connected to the electromagnet 10, the swing arm mechanism, and the power switch 4. In this embodiment, the storage battery 13 uses a 48V battery pack, which is electrically connected to the corresponding electrical equipment through the power line 14 to realize the mobile operation of the electromagnetic iron removal vehicle. The power switch 4 is located near the push-pull rod 5, so that when a person holds the push-pull rod 5 with one hand, they can operate the power switch 4 with the other hand to flexibly control the energization and de-energization of the electromagnet 10. Other function buttons can also be integrated on the power switch 4, such as the flipping and unloading of the electromagnet 10 and the reset of the electromagnet 10.
[0065] Furthermore, the present invention also provides an iron removal method for an electromagnetic iron removal vehicle, the iron removal method being implemented based on the aforementioned electromagnetic iron removal vehicle, and the iron removal method comprising:
[0066] Move the electromagnetic iron removal vehicle, which is currently in its original position, to the working position;
[0067] When the power switch 4 is turned on, the electromagnet 10 is energized. When energized, the electromagnet 10 attracts magnetic materials that have fallen onto the railway. At the same time, the magnetic field generated by the electromagnet 10 drives the car body 1 to move. This realizes the automated cleaning operation of the electromagnetic iron removal car along the direction of railway travel.
[0068] The vehicle's speed, steering, start and stop can be controlled by manual operation, with the push-pull lever 5 held manually.
[0069] After the electromagnet 10 collects a certain amount of magnetic material (the weight of the material can be monitored by a sensor), the swing arm mechanism drives the electromagnet 10 to flip above the collection port and enter the unloading state. In the unloading state, the electromagnet 10 is de-energized, the vehicle body 1 stops moving, and the magnetic material falls naturally into the collection box 2.
[0070] After unloading is completed, the electromagnet 10 is reset to its original position and then energized to start the operation again.
[0071] This invention cleverly utilizes the magnetic field generated by an energized electromagnet 10, which can attract magnetic materials while simultaneously moving the magnetic vehicle 1, improving operational convenience and work efficiency. Furthermore, unloading occurs when the vehicle 1 stops, allowing materials to fall more accurately into the collection box 2, reducing material spillage outside the collection box 2 during unloading and simplifying subsequent cleaning.
[0072] It should be understood that the above description of specific embodiments of the present invention is only for illustrating the technical approach and features of the present invention, and is intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the specific embodiments described above.
