Description

Technical Field

[0001] This utility model relates to the field of sliding contact line cleaning technology, and in particular to a sliding contact line cleaning device. Background Technology

[0002] In modern express sorting centers, automated sorting carts are widely used. These carts typically draw power from a structure consisting of a sliding contact line and a current collector to achieve continuous operation. However, during long-term use, friction between the carbon brushes of the current collector and the sliding contact line generates a large amount of carbon powder. This carbon powder accumulates on the surface of the sliding contact line, leading to poor contact between the sliding contact line and the current collector, generating electrical sparks, increasing contact resistance, not only wasting electrical energy but also potentially burning out the equipment and posing safety hazards. At the same time, it seriously affects the stability and reliability of the sorting system. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, this utility model is proposed.

[0004] The purpose of this utility model is to provide a sliding contact line cleaning device, which aims to solve the problem of poor power supply contact and safety hazards caused by carbon buildup on the sliding contact line of express sorting carts.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sliding contact line cleaning device, comprising,

[0006] Mounting plate for connecting to the sorting cart;

[0007] A sliding bracket is slidably mounted on the mounting plate;

[0008] The magnetic attraction assembly includes a permanent magnet fixed on the sliding frame and an electromagnet fixed on the mounting plate. When energized, the electromagnet generates a repulsive force with the permanent magnet.

[0009] An elastic reset element is connected between the mounting plate and the sliding frame, and is used to drive the sliding frame to reset to the initial position when the electromagnet is not energized;

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1

[0028] Reference Figures 1 to 4 As shown, this is the first embodiment of the present invention, which provides a sliding contact line cleaning device, including,

[0029] Mounting plate 1 is used to connect to the sorting cart;

[0030] The sliding bracket 2 is slidably mounted on the mounting plate 1;

[0031] The magnetic attraction component 3 includes a permanent magnet 31 fixed on the sliding frame 2 and an electromagnet 32 ​​fixed on the mounting plate 1. When the electromagnet 32 ​​is energized, it generates a repulsive force with the permanent magnet 31. The elastic reset component 4 is connected between the mounting plate 1 and the sliding frame 2 and is used to drive the sliding frame 2 to reset to the initial position when the electromagnet 32 ​​is not energized.

[0032] The cleaning assembly 5 includes a connecting plate 51, a drive wheel 52, and a cleaning wheel 53. The connecting plate 51 is connected to the sliding frame 2. The drive wheel 52 and the cleaning wheel 53 are rotatably connected to both ends of the connecting plate 51 via a rotating rod 54, and the drive wheel 52 and the cleaning wheel 53 are linked together via a transmission assembly 6.

[0033] In use: When the sorting trolley needs power, the control system energizes the electromagnet 32. The energized electromagnet 32 ​​generates a strong repulsive force with the permanent magnet 31. This repulsive force overcomes the tension of the elastic reset member 4, pushing the sliding frame 2 along with the entire cleaning assembly 5 downwards until the drive wheel 52 is reliably pressed against the sliding contact line. As the sorting trolley moves, the drive wheel 52 rolls on the sliding contact line and drives the cleaning wheel 53 to rotate synchronously in the opposite direction via the transmission assembly 6. The brush on the cleaning wheel 53 then cleans the carbon powder on the surface of the sliding contact line. When the sorting trolley stops working or cleaning is no longer needed, the power to the electromagnet 32 ​​is cut off. The repulsive force disappears, and the elastic reset member 4 pulls the sliding frame 2 back to its initial position, separating the drive wheel 52 and the cleaning wheel 53 from the sliding contact line to prevent idling and wear.

[0034] In summary, the automatic lifting and control of the cleaning device is achieved through the cooperation of the magnetic suction component 3 and the elastic reset component 4. The cleaning device only extends when the sorting trolley is powered on, solving the problem of poor contact caused by carbon buildup on the sliding contact line and ensuring power supply reliability. Simultaneously, it automatically retracts when not in operation, effectively reducing wear and extending the device's service life.

[0035] like Figures 1 to 3 As shown, in a preferred embodiment, the magnetic attraction component 3 and the elastic reset component 4 work together so that when the electromagnet 32 ​​is energized, the repulsive force overcomes the elastic force of the elastic reset component 4 and drives the sliding frame 2 to move downward, thereby making the drive wheel 52 in close contact with the sliding contact line.

[0036] In use: The energization of electromagnet 32 ​​is linked to the power supply signal of the sorting trolley. The electromagnet 32 ​​is energized at the same time when the trolley is powered, generating a precise downward thrust to ensure that the drive wheel 52 can contact the sliding contact line with the optimal pressure. This ensures sufficient friction to drive the sweeping wheel 53, while avoiding excessive pressure that could cause the drive wheel 52 to wear too quickly or have excessive resistance.

[0037] In summary, this preferred embodiment achieves intelligent linkage between the cleaning action and the working status of the sorting cart, with precise control, a high degree of automation, and ensures cleaning effect and equipment operating efficiency.

[0038] like Figure 3 As shown, in a preferred embodiment, the transmission assembly 6 includes transmission wheels 61 respectively fixed on the two rotating rods 54, and belts 62 sleeved on the two transmission wheels 61.

[0039] In use: When the drive wheel 52 rotates, it drives the transmission wheel 61 below to rotate through its rotating rod 54. The belt 62 transmits power to the transmission wheel 61 above, thereby driving the rotating rod 54 of the sweeping wheel 53 and the sweeping wheel 53 to rotate synchronously.

[0040] In summary, this preferred embodiment uses belt 62 drive, which has a simple and compact structure, smooth transmission, can effectively buffer impact loads, and is inexpensive, easy to maintain and replace.

[0041] like Figure 4 As shown, in a preferred embodiment, the sweeping wheel 53 includes a wheel body 531, a threaded rod 532, a knob 533, and a brush 534. The threaded rod 532 is threadedly connected to the wheel body 531. The knob 533 is located at the top of the threaded rod 532, and the brush 534 is located at the top of the knob 533. By rotating the knob 533, the threaded rod 532 can be separated from the wheel body 531, thereby allowing the brush 534 to be replaced.

[0042] When in use: When the brush 534 is severely worn and needs to be replaced, the operator can simply unscrew the entire threaded rod 532 along with the brush 534 from the wheel body 531 by hand or with the help of a simple tool by turning the knob 533. After replacing it with a new spare part, tighten it again. There is no need to disassemble the entire device.

[0043] In summary, this preferred embodiment features a quick-release sweeping wheel structure, which greatly reduces the difficulty and time cost of equipment maintenance and ensures efficient and continuous operation of the equipment.

[0044] like Figures 1 to 2 As shown, in a preferred embodiment, the mounting plate 1 is fixedly connected to the sorting trolley by bolts. The elastic reset member 4 is a tension spring, which pulls the sliding frame 2 to its highest point when the electromagnet 32 ​​is not energized.

[0045] In use: During installation, the mounting plate 1 is secured to the predetermined position on the chassis of the sorting trolley using bolts, ensuring a firm and reliable connection. The tension spring always provides an upward restoring force, ensuring that the device can quickly and completely disengage from the sliding contact line after power failure.

[0046] In summary: Bolted connections are easy to install, adjust, and disassemble. Using a tension spring as the reset element results in a simple structure, reliable performance, and rapid and effective reset.

[0047] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
