Description

Technical Field

[0001] This application relates to the field of track maintenance technology, and in particular to a track area clearing trolley. Background Technology

[0002] In urban rail transit construction, track area work is extensive and involves a large workload. Thorough cleaning after work is crucial for ensuring the safe and efficient operation of the subway. Currently, track area cleaning mainly relies on manual inspection, where workers enter the track area to remove metal particles after work is completed. This method is inefficient and time-consuming, especially in long sections, and cannot meet the current requirements for efficiency and reliability in cleaning work.

[0003] To address the aforementioned issues, Chinese utility model patent CN213978402U discloses a subway track maintenance device, which includes a base, a rotating wheel, and a magnetic block. The rotating wheel is movably mounted on the bottom of the base, allowing the base to move along the track; the magnetic block is fixedly installed on the bottom of the base and is used to attract metal particles from the track surface. Although the aforementioned subway track maintenance device can replace manual cleaning to some extent, its adaptability is limited because the magnetic block is a fixed installation structure, and the distance between the magnetic block and the track, induction plate, or ground is fixed. It cannot flexibly adapt to the installation environment of tracks in different track zones, resulting in poor versatility. Utility Model Content

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0020] See Figures 1-4 This invention illustrates a preferred embodiment of a track area clearing trolley, comprising: Frame 1; The traveling device 2 is located on the bottom of the frame 1 and is used to move the frame 1 along the track; and The magnetic component 3 is height-adjustable and is mounted on the frame 1. The magnetic component 3 is used to attract metal particles on the track surface.

[0021] The track area clearing trolley of this utility model, by adjusting the height of the magnetic suction component 3 on the frame 1, allows for flexible adjustment of the distance between the magnetic suction component 3 and the track, induction plate 9, or ground. This enables it to adapt to different track area installation environments, ensuring that the magnetic suction component 3 always maintains the optimal distance from the track, induction plate 9, or ground. This avoids insufficient adsorption force due to excessive distance and interference with surrounding components due to insufficient distance. As a result, the magnetic suction component 3 can stably adsorb metal particles on the track, induction plate 9, or ground, improving the stability and adaptability of the clearing operation, and enhancing the versatility of the track area clearing trolley in different track area environments.

[0022] In one embodiment, the magnetic component 3 is detachably mounted on the frame 1, meaning that the magnetic component 3 adopts a detachable design, allowing it to be easily removed from the frame 1. After removal, it can be used on track structures without the induction plate 9, and after installation, it can be used on track structures with the induction plate 9. Thus, the single track area clearing trolley meets diverse needs, improves applicability, and further enhances the versatility of the track area clearing trolley in different track area environments.

[0023] See Figure 1 In one embodiment, the number of magnetic assemblies 3 is at least five sets, wherein the at least five sets of magnetic assemblies 3 are arranged at intervals along the width direction of the frame 1; Of the at least five sets of magnetic adsorption components 3, one set is used to adsorb metal particles located at the outer edge of the first track 7 near the evacuation platform side, another set is used to adsorb metal particles between the induction plate 9 and the first track 7, another set is used to adsorb metal particles located at the outer edge of the second track 8 near the contact rail side, another set is used to adsorb metal particles on the top of the induction plate 9, and yet another set is used to adsorb metal particles located between the induction plate 9 and the second track 8. This achieves all-round adsorption of metal particles at the outer edge of the first track 7, between the induction plate 9 and the first track 7, at the outer edge of the second track 8, and between the induction plate 9 and the second track 8, which not only improves the efficiency of the clearing operation but also enhances its reliability.

[0024] Understandably, the magnetic components 34 in each of the above-mentioned magnetic assemblies 3 are 3 centimeters away from the ground to prevent interference and ensure smooth movement of the frame 1.

[0025] See Figures 1-4 In one embodiment, the frame 1 is provided with a connecting part 11, and the connecting part 11 has a first connecting hole 111; Magnetic component 3 includes: Adjustment component 31, which is movable up and down through the first connecting hole 111, and adjustment component 31 is provided with an external thread (not shown in the figure) extending vertically therein. The first locking component 32 is screwed onto the external thread portion. The first locking component 32 is located on the side near the top of the connecting portion 11 and can abut against the top of the connecting portion 11. The second locking member 33 is screwed onto the external threaded portion and is located on the side near the bottom of the connecting portion 11, abutting against the bottom of the connecting portion 11; and A magnetic suction component 34 is mounted on the adjusting component 31. The magnetic suction component 34 is used to attract metal particles from the track surface. To adjust the height of the magnetic suction component 34, first loosen the first locking component 32 and the second locking component 33, then move the adjusting component 31 to the desired position, and finally tighten the first locking component 32 and the second locking component 33. This structure not only allows for height adjustment and convenient disassembly of the magnetic suction component 34, but also offers simple operation and high practicality.

[0026] See Figures 1-4 To facilitate the easy installation of the magnetic component 34, in one embodiment, the magnetic assembly 3 further includes: Support component 35 is disposed on adjustment component 31, and magnetic suction component 34 is disposed on support component 35.

[0027] See Figures 1-4 In one embodiment, the adjusting component 31 is a screw, and the first locking component 32 and the second locking component 33 are both nuts. By setting the adjusting component 31 as a screw and setting both the first and second locking components 33 as nuts, the transmission and locking characteristics of the threaded pair are utilized to achieve stepless and precise height adjustment and reliable locking. Its structure is compact, highly standardized, low in manufacturing cost, and easy to operate, thus realizing the core functions of adjustment and locking with the simplest and most stable mechanical structure.

[0028] Of course, in other embodiments, the adjusting component 31 can also be a bolt, and the first locking component 32 and the second locking component 33 can both be nuts.

[0029] Of course, in other embodiments, the magnetic component 3 may include: A pin rod having a plurality of positioning holes arranged sequentially along its height direction; A pin, located on the frame 1, is provided; the pin rod can be inserted into any positioning hole. The magnetic suction component 34 is mounted on the pin. This structure also allows for adjustment of the height of the magnetic suction component 34.

[0030] Of course, in other embodiments, the magnetic component 3 may include: A pillar, extending vertically; The clamp is mounted on the frame 1 and surrounds the support column. The clamp has a fastening bolt; tightening the bolt secures the clamp to the support column, while loosening the bolt allows the support column to slide up and down, achieving stepless height adjustment. The magnetic suction component 34 is mounted on the support column. This structure also allows for adjustment of the height of the magnetic suction component 34.

[0031] In one embodiment, the magnetic attraction component 34 may specifically be one or a combination of a permanent magnet (i.e., a magnet) and an electromagnet.

[0032] See Figures 1-3 In one implementation, the track area clearing trolley further includes: The current collector shoe simulation component 4 is mounted on the frame 1 in a floating manner to ensure that the current collector shoe simulation component 4 can be adaptively adjusted when the contact rail is uneven, thereby ensuring that the current collector shoe simulation component 4 can slide smoothly along the contact rail. The current collector shoe simulation component 4 is used to slide with the contact rail when the frame 1 moves along the rail. Camera 5, mounted on the frame 1, is electrically connected to a mobile terminal (not shown in the figure). Camera 5 is used to capture real-time images of the contact between the current collector shoe simulation component 4 and the contact rail, and transmits the image data to the mobile terminal. The current collector shoe simulation component 4 enables the track clearing trolley to perform contact rail cold-slip simulation tests. When the track clearing trolley moves along the track, the current collector shoe simulation component 4 slides along the unenergized contact rail. Simultaneously, camera 5 captures real-time images of the contact between the current collector shoe simulation component 4 and the unenergized contact rail, and transmits the image data to the mobile terminal (such as a mobile phone, tablet, or monitoring screen) via a wireless network. This allows for dynamic detection of the mechanical performance of the contact rail. As a result, staff can intuitively analyze the following performance, contact force, and friction between the current collector shoe simulation component 4 and the contact rail, ensuring that staff can accurately detect installation deviations in the height and horizontal directions of the contact rail and check for abnormal friction, scratches, or other defects on the working surface of the contact rail. This allows for timely identification and elimination of potential engineering quality and safety hazards, ensuring the safe operation of subsequent trains.

[0033] It is understandable that the contact rail cold-slip simulation test is a crucial clearance detection and functional verification test conducted on urban rail transit (subways, trams, etc.) after the construction of new lines or after major line overhauls and before the official power supply and operation. Under absolutely safe (no power) conditions, it simulates the interaction between the current collector shoe and the contact rail of the future train, and discovers and eliminates all potential mechanical interference, collision or wear risks in advance.

[0034] See Figures 1-3 In one implementation, the track area clearing trolley further includes: The swing component 6 has its first end pivotally connected to the frame 1 via a pivot, allowing the swing component 6 to swing up and down. The second end of the swing component 6 supports the current collector shoe simulation component 4. elastic components ( Figures 1-4(Not shown in the structure) The first end of the elastic component is connected to the frame 1, and the second end of the elastic component is connected to the second end of the swing component 6. The elastic component provides an elastic force to the current collector shoe simulation component 4 to keep it in contact with the contact rail. In this way, through the cooperation of the swing component 6 and the elastic component, the current collector shoe simulation component 4 can adaptively swing up and down, thereby effectively compensating for the height unevenness of the contact rail or the attitude change of the track clearing trolley during movement, ensuring the continuity and stability of the contact force between the current collector shoe simulation component 4 and the contact rail, and guaranteeing the reliability and stability of the contact rail mechanical performance detection.

[0035] For ease of installation, in one embodiment, the frame 1 has a second connecting hole 112, and the swing component 6 has a third connecting hole 61; The first end of the elastic component is provided with a first hook, which is hooked onto the second connecting hole 112. The second end of the elastic component is provided with a second hook, which is hooked onto the third connecting hole 61.

[0036] See Figure 1 In one embodiment, the swing component 6 is provided with a plurality of third connection holes 61 along its transverse direction, and the second hook can be hooked onto any one of the third connection holes 61 so that the height position of the second end of the swing component 6 can be adjusted, thereby enabling the current collector shoe simulation component 4 to adapt to the contact rail of different track areas and improve versatility.

[0037] In one embodiment, the current collector shoe simulation component 4 is a structure made of rubber or plastic material to give the current collector shoe simulation component 4 a certain degree of flexibility and prevent scratching the contact rail.

[0038] To improve the movement stability of frame 1, see Figure 1 In one embodiment, the walking device 2 includes four walking wheels 21, which are rotatably disposed at the four corners of the frame 1.

[0039] In one implementation, the track area clearing trolley further includes: Handrail 10 is provided on the frame 1 and is used for the operator to support the frame 1 so as to facilitate the movement of the frame 1 along the track.

[0040] In one implementation, the track area clearing trolley further includes: The brake (not shown in the figure) is mounted on the frame 1 and is used to control the stopping of the traveling wheels 21 so that the traveling wheels 21 can stop rotating smoothly.

[0041] Of course, in other embodiments, the walking device 2 can specifically be the structure of the automated walking wheel 21 commonly used in the market.

[0042] In one embodiment, the frame 1 is made of composite materials or aluminum alloy, which reduces the overall weight of the vehicle, increases the comfort of workers in handling the vehicle, and effectively improves work efficiency.

[0043] The track area clearing trolley of this utility model has the following advantages: 1. The traveling device 2 enables the track area clearing trolley to move smoothly on the track; 2. It integrates multiple functions such as magnetic adsorption, contact rail cold sliding simulation, clearance detection and video recording: Among them, the magnetic adsorption component 3 can effectively remove residual ferromagnetic foreign objects from the track bed, equipment gaps and rail bottom, improving the cleaning effect and efficiency; at the same time, other functions work together to effectively solve the problem of incomplete manual cleaning based on comprehensive inspection and recording of equipment in the track area, thereby significantly reducing the safety risks of subway operation the next day.
