Description

Technical Field

[0001] The utility model relates to the technical field of track cleaning, in particular to a vehicle power supply track cleaning structure and a cleaning system. Background Art

[0002] During the liquor brewing process, the brewing environment is humid and the steam used for distillation contains a variety of organic compounds that mix with stains in the environment and adhere to the power supply track. After the powered pulley of the traveling crane continuously rolls back and forth, a stubborn oil film is formed on the power supply track, which increases the contact resistance between the track and the pulley. This will greatly reduce the conductivity of the track. At the same time, there is also the problem of poor track contact, which causes sparks to be generated during the operation of the slide rail, and even the phenomenon of power failure and damage to the electrical components of the traveling crane due to phase loss.

[0003] When cleaning the power supply rails, the traditional method is usually to use manual grinding and cleaning. Manual grinding and cleaning is not only time-consuming and labor-intensive, but also has poor results and causes great wear and tear on the power supply rails. In addition, there are certain safety risks of electric shock and working at heights. Utility Model Content

[0026] Example 1

[0027] like Figure 1 As shown, the utility model provides a technical solution:

[0028] A vehicle power supply track cleaning structure, which at least includes but is not limited to a guide cavity 1 and a scraper 2; an electromagnet 3 is arranged in the guide cavity 1; an end opening of the guide cavity 1 away from the electromagnet 3 is arranged, at least the end of the scraper 2 is sleeved in the guide cavity 1, and a limit strip 4 can be arranged at the open end of the guide cavity 1; a magnetic attraction part 5 is arranged at a position of the scraper 2 close to the electromagnet 3; the scraper 2 can move along the length direction of the guide cavity 1, and the electromagnet 3 can make the magnetic attraction part 5 move closer to or away from the electromagnet 3 under the action of magnetic force.

[0029] Based on the above structure, when the electromagnet 3 is conductive, the scraper 2 extends outward a predetermined distance under the action of magnetic force, and is stuck by the limit strip 4 at the extreme position. The limit strip 4 can prevent the scraper 2 from completely detaching from the guide cavity 1. The extended scraper 2 can run along the conductive track 18 driven by external power, thereby achieving the removal of stains on the surface of the conductive track 18. When scraping operation is not required, the electromagnet is non-conductive, so that the scraper 2 is close to the electromagnet 3 under the action of magnetic attraction, avoiding the scraper 2 from operating on the conductive track 18 for a long time, making it more flexible in use and safer in operation.

[0030] As an example, the guide cavity 1 is a rectangular structure as a whole, and a wire through hole 6 is provided on the guide cavity 1. The wire through hole 6 is provided on the wall surface of the guide cavity 1 away from the opening end;

[0031] The scraper 2 may include a connecting column 7, an extension column 8 and a blade body 9; the connecting column 7, the extension column 8 and the blade body 9 are connected in sequence, the magnetic attraction portion 5 is arranged on the end surface of the connecting column 7 away from the extension column 8, the magnetic attraction portion 5 is a rectangular structure whose size is adapted to the structure of the guide cavity 1, the connecting column 7 is the same size as the magnetic attraction portion 5, and the end of the blade body 9 is a sharp structure; the blade body 9 and the connecting column 7 are detachably connected;

[0032] Based on the above structure, the magnetic attraction part 5 and the connecting column 7 are set to a rectangular structure. On the one hand, the connecting column 7 can move along the length direction of the guide cavity 1. On the other hand, the rectangular connecting column 7 and the rectangular cavity structure can prevent the knife body part 9 from rotating, so that the knife body will not shake when extending outward.

[0033] As an example, the contact surface between the connecting column 7 and the limiting strip 4 is chamfered, so as to avoid rigid contact between the connecting column 7 and the limiting strip 4 and avoid damage to the limiting strip 4.

[0034] As an example, a snap-fit ​​cavity (not shown) may be provided in the extension column 8, a snap-fit ​​column (not shown) matching the snap-fit ​​cavity may be provided on the blade body 9, and a locking groove (not shown) may be provided on the snap-fit ​​column; a matching hole 10 perpendicular to the snap-fit ​​cavity is provided on the side wall of the extension column 8, and a bolt 11 passes through the matching hole 10 and the locking hole to connect the blade body 9 and the extension column 8 as a whole.

[0035] Based on the above structure, the blade body 9 can be quickly disassembled and assembled by providing a clamping structure, thereby simplifying the difficulty of subsequent maintenance.

[0036] As an example, the blade body 9 can include a first curved end face 21 and a second curved end face 22; the ends of the first curved end face 21 and the second curved end face 22 intersect to form a sharp end; the curvature of the first curved end face 21 is not less than the curvature of the second curved end face 22; the second curved end face 22 is arranged close to the conductive track 18 during assembly.

[0037] Based on the above structure, due to the special arrangement of the first arcuate end surface 21 and the second arcuate end surface 22, when scraping the material, the impurities will move along the length direction of the first arcuate end surface 21, and thus be thrown away from the position where the conductive track 18 is located.

[0038] As an example, the electromagnet may include a coil 31 and an iron core 32 ; blocking disks are provided at both ends of the iron core 32 , and the coil 31 is sleeved between the two blocking disks on the iron core 32 .

[0039] Specifically, the magnetic attraction portion 5 may be a rubber-coated neodymium magnet; the blade body portion 9 is a polyurethane scraper 2; and the guide cavity 1 is a MC nylon shell.

[0040] Based on the above structure, the polyurethane scraper 2 adopts a high molecular polyurethane material with low friction coefficient, high wear resistance, acid resistance, impact resistance, little damage to the driving power supply track, and no food safety risk. At the same time, the polyurethane scraper 2 can be disassembled and replaced, and the maintenance cost is low. The MC nylon shell adopts MC nylon material with light weight, high strength, self-lubrication, wear resistance, corrosion resistance, insulation and other properties. At the same time, it is non-magnetic and can eliminate interference with the movement of the rubber-coated neodymium magnet in the shell. The rubber-coated neodymium magnet has extremely strong magnetic force and is resistant to demagnetization. At the same time, the rubber coating of the neodymium magnet improves its impact resistance.

[0041] Example 2

[0042] like Figure 2 As shown, based on the above embodiment 1, the utility model provides a technical solution:

[0043] A vehicle power supply track cleaning system includes multiple cleaning structures and connecting rods 12, one end of the connecting rod 12 is connected to the cleaning structure, and the other end is connected to the support rod 15 of the pantograph; the cleaning structure and the connecting rod 12 are symmetrically arranged on both sides of the pantograph.

[0044] Based on the above structure, by providing a cleaning structure for scraping in two directions on each conductive rail 18, it can be ensured that the pantograph can scrape dirt when moving forward or backward.

[0045] The pantograph in this scheme is arranged on each guide rail, and the pantograph includes conductive rollers 13, contact rods 14 and support rods 15 on both sides. The contact rods 14 are hinged to both ends of the support rods 15 respectively, and the conductive rollers 13 are arranged on the ends of the contact rods 14 away from the support rods 15. Spring members 16 are arranged between adjacent contact rods 14; the support rods 15 are connected as a whole through the same active rod 17.

[0046] Driven by the active rod 17, all pantographs and cleaning structures move synchronously. A normally open self-locking button switch is set in the driving cab. When the driver presses the button, the DC coil 31 is energized, so that the coil 31 forms a magnetic field opposite to the magnetic field of the rubber-coated neodymium magnet. According to the principle that magnetic poles of the same name repel each other, the rubber-coated neodymium magnet moves away from the DC coil 31. The polyurethane scraper 2 is pushed out of the MC nylon shell by the thrust of the rubber-coated neodymium magnet. At this time, the tip of the polyurethane scraper 2 is pressed on the power supply track. When the vehicle moves, the polyurethane scraper 2 is driven to scrape off the oily diaphragm on the surface of the power supply track. After the cleaning is completed, the driver presses the button again, the DC coil 31 loses power, the magnetic field of the coil 31 disappears, and the strong magnetic force of the rubber-coated neodymium magnet attracts the ferromagnetic material in the DC coil 31, and the polyurethane scraper 2 is retracted into the shell. According to the actual situation on site, cleaning can be carried out regularly every week or every month to reduce the wear on the polyurethane scraper 2 and the power supply track.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
