For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0031] Referring to Figure 1 The utility model embodiment provides a slide wire current collector, including mounting seat 1, through mounting seat 1 will be fixedly installed current collector to corresponding need to move the equipment of power supply. Referring to Figure 2 As shown in the figure, the mounting seat 1 top is provided with installation cavity 11, and the first telescopic mechanism 2 and telescopic section 3 are arranged in the installation cavity 11. The telescopic end of the first telescopic mechanism 2 is in close contact with the end of the telescopic section 3 located in the installation cavity 11, and the first telescopic mechanism 2 is used to drive the telescopic section 3 to longitudinally slide in the installation cavity 11, to ensure that when the relative distance between the current collector end and the slide bus changes, the current collector and the slide bus always have good contact power taking ability through the longitudinal sliding of the telescopic section 3 driven by the first telescopic mechanism 2. Referring to Figure 1 As shown in the figure, the end of the telescopic section 3 away from the first telescopic mechanism 2 is located outside the mounting seat 1. Referring to Figure 3 As shown in the figure, the end of the telescopic section 3 away from the first telescopic mechanism 2 is located outside the mounting seat 1. Referring to Figure 2 As shown in the figure, the second telescopic mechanism 4 and the power taking carbon brush 5 are arranged in each installation recess 31, one end of the second telescopic mechanism 4 is fixed at the bottom of the installation recess 31, the other end of the second telescopic mechanism 4 is in close contact with the end of the corresponding power taking carbon brush 5 located in the installation recess 31, and the end of the power taking carbon brush 5 away from the second telescopic mechanism 4 is located outside the telescopic section 3. The second telescopic mechanism 4 is used to drive the corresponding power taking carbon brush 5 to longitudinally slide in the corresponding installation recess 31. The second telescopic mechanism 4 in each installation recess 31 drives the corresponding power taking carbon brush 5 to longitudinally slide respectively, and the two power taking carbon brushes 5 are independent of each other and do not affect each other. When the single-row slide wire is inconsistent in the curvature radius due to the distortion, local bending and other conditions in the actual laying process of the slide wire, each power taking carbon brush 5 can have good contact ability with the corresponding slide wire.
[0032] It can be understood that the two power taking carbon brushes 5 are connected with the lead connector 6, and the current collector and the equipment needing mobile power supply are electrically connected through the lead connector 6, so that the power taking carbon brush 5 transmits electric energy from the slide wire to the equipment.
[0033] Referring to Figure 2 And Figure 5As shown, in the embodiment, the first telescopic mechanism 2 comprises a bottom plate 21 and a first spring 22. The bottom plate 21 is detachably fixed to the bottom of the mounting seat 1. Preferably, four connecting blocks 24 with mounting holes are respectively arranged at the top corners of the bottom plate 21, and the bottom plate 21 is installed at the bottom of the mounting cavity 11 through the four connecting blocks 24. The bottom plate 21 and the first spring 22 are convenient to disassemble and maintain. One end of the first spring 22 is sleeved outside the outer periphery of the boss 23 at the top of the mounting seat 1, and the other end of the first spring 22 is located in the first blind hole 32 at the bottom of the telescopic section 3. Preferably, two bosses 23 are symmetrically arranged at the top of the bottom plate 21, two first blind holes 32 are symmetrically arranged at the bottom of the telescopic section 3, and one first spring 22 is arranged between the two bosses 23 and the two first blind holes 32. The arrangement of the two symmetric first springs 22 makes the telescopic section 3 bear force evenly, ensures that the telescopic section 3 does not deviate laterally when sliding longitudinally in the mounting cavity 11, that is, ensures that the telescopic section 3 slides longitudinally more smoothly and sensitively, and thus ensures that the first telescopic mechanism 2 can drive the telescopic section 3 to slide longitudinally to make the current collector have good contact and power collection ability with the sliding contact bus at any time when the relative distance between the current collector and the sliding contact bus changes.
[0034] Preferably, as shown in Figure 2 As shown, the bottom ends of the left and right sides of the telescopic section 3 are respectively provided with an outwardly extending outer limiting portion 34, and the top of the left and right sides of the mounting cavity 11 is respectively provided with an inwardly extending inner limiting portion 12. After installation, the outer limiting portion 34 and the inner limiting portion 12 limit the telescopic section 3 from sliding out of the mounting cavity 11.
[0035] As shown in Figure 2 and Figure 4 As shown, in the embodiment, the second telescopic mechanism 4 comprises a guide circular platform 41, a second spring 42 and a cover 43. Two guide circular platforms 41 are symmetrically arranged on the side surface of the end of the telescopic section 3 away from the first telescopic mechanism 2, and two waist-shaped holes 51 with diameters matching those of the guide circular platforms 41 are arranged on the power collection carbon brush 5. The two guide circular platforms 41 are respectively arranged in the two waist-shaped holes 51. Through the cooperation of the guide circular platforms 41 and the waist-shaped holes 51, the power collection carbon brush 5 can only move longitudinally. The second springs 42 are evenly arranged between the bottom of the power collection carbon brush 5 and the bottom of the mounting groove 31. Through the arrangement of the second springs 42, the power collection carbon brush 5 bears force evenly, ensuring that the power collection carbon brush 5 does not deviate laterally when sliding longitudinally in the mounting groove 31, that is, ensuring that the power collection carbon brush 5 slides longitudinally more smoothly and sensitively, and ensuring that each power collection carbon brush 5 has good contact ability with the corresponding sliding contact line when the single-row sliding contact line has inconsistent curvature radii due to twisting, local bending and other situations during the actual laying of the sliding contact line. The cover 43 covers the outside of the mounting groove 31, and the cover 43 plays a protective role for the second telescopic mechanism 4.
[0036] Further, as shown in Figure 2As shown, the second telescopic mechanism 4 further comprises a retainer 44 connected between the two guide circular platforms 41, which can limit the lateral movement of the current collector carbon brush 5 when the current collector carbon brush 5 slides longitudinally in the mounting groove 31.
[0037] Further, referring to Figure 4 As shown, the end of the current collector carbon brush 5 in the mounting groove 31 is uniformly provided with a plurality of positioning grooves 52, and the bottom of the mounting groove 31 is uniformly provided with a plurality of second blind holes 33, and one second spring 42 is arranged between each positioning groove 52 and corresponding second blind hole 33, so that the second spring 42 will not be offset during the telescopic process through the limiting of the positioning groove 52 and the second blind hole 33, thereby improving the service life of the second telescopic mechanism 4.
[0038] Preferably, the positioning groove 52 and the second blind hole 33 are both four.
[0039] The working principle of the utility model:
[0040] After initial installation, the position between the current collector and the sliding bus is appropriately adjusted, so that the first spring 22 of the first telescopic mechanism 2 and the second spring 42 of the second telescopic mechanism 4 are in a compressed state, so as to ensure that the two current collector carbon brushes 5 are in close contact with the sliding bus and have good contact power collection ability.
[0041] During the sliding process of the current collector on the sliding bus, when the relative distance between the end of the current collector and the sliding bus changes, the first spring 22 of the first telescopic mechanism 2 drives the telescopic section 3 to slide longitudinally in the mounting cavity 11 in real time, so that the two current collector carbon brushes 5 of the current collector always have good contact power collection ability with the sliding bus.
[0042] When the sliding wire is twisted, locally bent or the like during actual laying, resulting in inconsistent curvature radius of the single-row sliding wire, the second spring 42 of each second telescopic mechanism 4 drives the current collector carbon brush 5 to slide longitudinally in the corresponding mounting groove 31 in real time, so that the corresponding current collector carbon brush 5 can have good contact ability with the corresponding sliding wire.
[0043] The above describes the preferred embodiment of the utility model in detail, which cannot be considered as limiting the scope of the utility model. Any equivalent changes and improvements within the scope of the utility model application shall still belong to the patent coverage of the utility model.
