Description

Technical Field

[0001] The invention relates to the technical field of logistics sorting trolleys, and in particular to a power receiving structure of a rail power supply trolley. Background Art

[0002] At present, the existing rail power supply trolleys basically rely on brushes set at the bottom of the trolley to draw power from the power supply track. The conductive rails of the power supply track are composed of multiple parallel conductive rails. Brushes corresponding to each conductive rail are set at the bottom of the trolley. The running wheels on both sides of the trolley are set on both sides of the trolley to clamp the trolley on the power supply track.

[0003] There are certain problems with the electrical connection structure between the power supply rail and the trolley:

[0004] 1. The conductive rail is exposed to the outside, which poses a safety hazard;

[0005] 2. Since the trolley is wrapped around the power supply track, the size of the trolley is relatively large. In addition, due to the size of the trolley, the curvature of the power supply track cannot be too small, otherwise the trolley will get stuck easily when turning. Therefore, the existing sorting system composed of track-powered trolleys needs to occupy a large area, making the entire sorting system too large.

[0006] In response to the above problems, there are also power supply rails with side contacts for power supply. That is, the conductive rails are set on both sides of the rails, and the brush assembly of the trolley is clamped on the conductive rails to draw power from the conductive rails. This structure can effectively avoid the direct exposure of the conductive rails, and can reduce the volume of the power supply rails, so that the volume of the trolley can be made smaller. But this also brings a new problem: it is difficult to realize lane change power supply. Since the guide rails are set on both sides of the power supply rail body in reverse, if the power supply rails cross, when changing lanes, the brush assembly on one side cannot contact the power supply rail, otherwise it will hinder the trolley from changing lanes. This causes the trolley to lift the brush on one side to avoid the power supply rail when changing lanes, resulting in the trolley being powered off. Although the trolley's inertia allows the trolley to change lanes smoothly, each power outage after changing lanes will cause the trolley's sorting control data to be lost, affecting the normal trolley sorting. Summary of the invention

[0007] In view of the problems existing in the prior art, the main purpose of the present invention is to provide a power receiving structure of a track power supply trolley, which can ensure that the track power supply trolley can normally draw power from the power supply track while changing lanes.

[0008] To achieve the above-mentioned purpose, the power receiving structure of the rail power supply trolley proposed in the present invention includes a power supply track that carries and supplies power to the rail power supply trolley, and a brush assembly arranged on the rail power supply trolley. The power supply track includes a U-shaped combined profile, the combined profile has a U-shaped accommodating cavity, and mounting grooves are respectively recessed on both sides of the accommodating cavity, and the two mounting grooves are provided with conductive rails.

[0009] The brush assembly is arranged between the two side running wheels of the track power supply trolley, and the number of the brush assembly is at least two, and they are arranged along the moving direction of the track power supply trolley. Each brush assembly includes a sleeve fixed to the bottom of the track power supply trolley, and the sleeve is inserted into the U-shaped accommodating cavity of the combined profile. Two conductive brushes facing each other are arranged on the sleeve, and the two conductive brushes are inserted into the two conductive rails of the U-shaped accommodating cavity.

[0010] Optionally, at least two guide wheels are disposed outside the shaft sleeve, and outer wheel surfaces of the guide wheels are in contact with inner walls of the U-shaped accommodating cavity.

[0011] Optionally, the inner wall of the U-shaped accommodating cavity is provided with a plurality of first friction ribs arranged in parallel.

[0012] Optionally, the upper end surface of the power supply track is a supporting surface, and the running wheels of the track power supply trolley are in contact with the supporting surface.

[0013] Optionally, a plurality of second friction ribs arranged in parallel are provided on the support surface.

[0014] Optionally, the conductive rail comprises an insulating rail and a power transmission rail, the insulating rail is arranged at the bottom of the mounting groove, and the power transmission rail is arranged on a side of the insulating rail away from the bottom of the mounting groove.

[0015] Optionally, a transversely arranged T-shaped protrusion is provided at the bottom of the mounting groove, and a T-shaped groove corresponding to the T-shaped protrusion is provided at the bottom of the insulating rail.

[0016] Optionally, the combined profile includes two symmetrically arranged supporting profiles and a bottom profile, and the facing sides of the two supporting profiles are respectively buckled on the two sides of the bottom profile to form a U-shaped accommodating cavity.

[0017] Optionally, vertical hook grooves are respectively provided on both sides of the upper end surface of the bottom profile, and a hook corresponding to the hook groove is provided on one side of the supporting profile close to the bottom profile. During assembly, the hook is buckled in the hook groove of the bottom profile.

[0018] The present invention adopts a composite profile with a U-shaped accommodating cavity as a track for carrying a rail power supply trolley, and sets relatively arranged conductive rails in the U-shaped accommodating cavity of the composite profile to form a power supply track. At the same time, a plurality of brush assemblies arranged along the movement direction of the rail power supply trolley are set between the running wheels on both sides of the bottom of the rail power supply trolley. Specifically, the brush assembly includes a shaft sleeve fixed to the bottom of the rail power supply trolley, the shaft sleeve is inserted into the U-shaped accommodating cavity of the composite profile, and two conductive brushes facing each other are set thereon, and the two conductive brushes are respectively inserted into the two conductive rails of the U-shaped accommodating cavity.

[0019] By arranging the conductive rail inside the combined profile, the brush assembly will not interfere with the track power supply trolley when the track power supply trolley changes lanes;

[0020] Since the conductive rails are arranged relative to each other, a connection area will be formed at the intersection and convergence position. When the brush assembly of the track power supply trolley enters the connection area, power outage will also occur. By setting the number of brush assemblies to at least two and arranging them along the movement direction of the track power supply trolley, when the brush assembly on the front side of the track power supply trolley enters the connection area, the brush assembly on the rear side of the track power supply trolley can draw power from the power supply track before changing lanes; when the brush assembly on the front side of the track power supply trolley enters the power supply track after changing lanes, even if the brush assembly on the rear side of the track power supply trolley enters the connection area, the brush assembly on the front side of the track power supply trolley can draw power from the power supply track after changing lanes, thereby ensuring that the track power supply trolley does not lose power during the lane change process.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Please refer to the instruction manual Figure 1 In an embodiment of the present invention, a power receiving structure of a rail power supply trolley is proposed, and the power receiving structure of the rail power supply trolley 2 includes a power supply track 1 that carries and supplies power to the rail power supply trolley 2, and a brush assembly 22 arranged on the rail power supply trolley 2. The power supply track 1 includes a U-shaped combined profile, the combined profile has a U-shaped accommodating cavity, and mounting grooves 11a are respectively recessed on both sides of the accommodating cavity, and the two mounting grooves 11a are provided with conductive rails 111.

[0028] The brush assembly 22 is arranged between the two side running wheels 21 of the track power supply trolley 2, and the number of the brush assembly 22 is at least two, and they are arranged along the moving direction of the track power supply trolley 2. Each brush assembly 22 includes a shaft sleeve 221 fixed to the bottom of the track power supply trolley 2, and the shaft sleeve 221 is inserted into the U-shaped accommodating cavity of the combined profile. Two conductive brushes 222 facing each other are arranged on the shaft sleeve 221, and the two conductive brushes 222 are inserted into the two conductive rails 111 of the U-shaped accommodating cavity.

[0029] The present invention adopts a composite profile with a U-shaped accommodating cavity as a track for carrying the rail power supply trolley 2, and sets relatively arranged conductive rails 111 in the U-shaped accommodating cavity of the composite profile to form a power supply track 1. At the same time, a plurality of brush assemblies 22 arranged along the movement direction of the rail power supply trolley 2 are set between the running wheels 21 on both sides of the bottom of the rail power supply trolley 2. Specifically, the brush assembly 22 includes a shaft sleeve 221 fixed to the bottom of the rail power supply trolley 2, the shaft sleeve 221 is inserted into the U-shaped accommodating cavity of the composite profile, and two conductive brushes 222 facing each other are set thereon, and the two conductive brushes 222 are respectively inserted into the two conductive rails 111 of the U-shaped accommodating cavity.

[0030] By arranging the conductive rail 111 inside the combined profile, the brush assembly 22 will not interfere with the track power supply trolley 2 when the track power supply trolley 2 changes lanes.

[0031] Since the conductive rails 111 are arranged relative to each other, a connection area will be formed at the intersection and convergence position. When the brush assembly 22 of the track power supply trolley 2 enters the connection area, power outage will also occur. By setting the number of brush assemblies 22 to at least two and arranging them along the movement direction of the track power supply trolley 2, when the brush assembly 22 on the front side of the track power supply trolley 2 enters the connection area, the brush assembly 22 on the rear side of the track power supply trolley 2 can draw power from the power supply track 1 before changing lanes; when the brush assembly 22 on the front side of the track power supply trolley 2 enters the power supply track 1 after changing lanes, even if the brush assembly 22 on the rear side of the track power supply trolley 2 enters the connection area, the brush assembly 22 on the front side of the track power supply trolley 2 can also draw power from the power supply track 1 after changing lanes, thereby ensuring that the track power supply trolley 2 does not lose power during the lane change process.

[0032] Optionally, in this embodiment, at least two guide wheels 223 are disposed outside the shaft sleeve 221, and the outer wheel surface of the guide wheel 223 contacts the inner wall of the U-shaped accommodating cavity. Thus, the guide wheels 223 can provide guiding support for the turning of the rail power supply trolley 2, ensuring the stability of the turning of the rail power supply trolley 2.

[0033] Optionally, the inner wall of the U-shaped accommodating cavity is provided with a plurality of first friction ribs 11c arranged in parallel. Since the guide wheel 223 will frequently contact and rub against the inner wall of the U-shaped accommodating cavity, the inner wall of the U-shaped accommodating cavity will be worn. Therefore, in this embodiment, a plurality of first friction ribs 11c arranged in parallel are provided on the inner wall of the U-shaped accommodating cavity, so as to improve the wear resistance of the inner wall of the U-shaped accommodating cavity.

[0034] Optionally, in the embodiment, the upper end surface of the power supply track 1 is a support surface, the running wheel 21 of the track power supply trolley 2 is in contact with the support surface, and a plurality of second friction ribs 11d arranged in parallel are provided on the support surface. The running wheel 21 of the track power supply trolley 2 will generate friction with the upper end surface of the power supply track 1 when moving. By providing the second friction ribs 11d on the support surface, the service life of the power supply track 1 can be effectively improved, and the running wheel 21 of the track power supply trolley can be prevented from slipping.

[0035] Optionally, in this embodiment, the conductive rail 111 includes an insulating rail 1111 and a power transmission rail 1112, wherein the insulating rail 1111 is disposed at the bottom of the mounting groove 11a, and the power transmission rail 1112 is disposed at a side of the insulating rail away from the bottom of the mounting groove 11a, thereby preventing the power transmission rail 1112 of the conductive rail 111 from directly contacting the combined profile and causing leakage.

[0036] Optionally, in this embodiment, a transversely arranged T-shaped protrusion 11b is provided at the bottom of the mounting groove 11a, and a T-shaped slot corresponding to the T-shaped protrusion 11b is provided at the bottom of the insulating rail 1111. During assembly, the T-shaped slot at the bottom of the insulating rail 1111 can be tightly fastened to the T-shaped protrusion 11b to prevent the conductive rail 111 from loosening.

[0037] Optionally, in this embodiment, the combined profile includes two symmetrically arranged support profiles 11 and a bottom profile 12, and the facing sides of the two support profiles 11 are respectively buckled on the two sides of the bottom profile 12 to form a U-shaped accommodating cavity. The mounting groove 11a is arranged on the inner side of the support profile 11.

[0038] Specifically, vertical hook grooves 12a are respectively provided on both sides of the upper end surface of the bottom profile 12, and a hook 12e corresponding to the hook groove 12a is provided on the side of the support profile 11 close to the bottom profile 12. During assembly, the hook 11e of the support profile 11 is buckled into the hook groove 12a of the bottom profile 12 to quickly splice to obtain a combined profile.

[0039] The combined profile adopts a split design. During assembly, the conductive rail 111 can be first installed in the installation groove 11a, and then the supporting profile 11 and the bottom profile 12 are combined into a complete power supply track 1, which greatly improves the assembly efficiency of the power supply track 1.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to be construed as limiting the present invention. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
