DETAILED DESCRIPTION
[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "page", "bottom", "inner", "outer", "clockwise", "counterclockwise", "coaxial", "bottom", "one end", "top", "other end", "one side", "front", "both ends", "both sides", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] Referring now to the accompanying drawings, the various figures are intended only to illustrate certain exemplary embodiments and are not intended to limit the scope of the invention. In the various figures, the same reference numerals denote the same or corresponding parts. The dimensions and scales in the various figures are also for illustrative purposes only and should not be construed as limiting the scope of the invention; these dimensions may be enlarged relative to actual products.
[0027] Reference Figures 1-4 The variable track transport trolley shown includes a track body 1, a transport trolley structure 2 is provided on the top of the track body 1, and a drive structure 3 is provided between the track body 1 and the transport trolley structure 2.
[0028] The drive structure 3 includes a rotating frame 301 with fitting grooves 302 at both ends. A worm gear body 303 is located at the middle of the top of the rotating frame 301, and a rotating plate 304 is located at one end of the bottom of the worm gear body 303. Drive wheels 305 are rotatably connected to both ends of the inner side of the rotating plate 304. The drive wheels 305 are located inside the track body 1. The worm gear body 207 drives the worm gear body 303 to rotate, and the worm gear body 303 drives the rotating frame 301 to rotate along the connection position between the fitting groove 302 and the mounting block 206. Then, the worm gear body 303 drives the rotating plate 304 to rotate, and the rotating plate 304 drives the drive wheel 305 to separate from the outer wall of the track body 1. At the same time, the auxiliary wheel 210 is used to support the moving frame 201. After the conveying trolley structure 2 has completely passed the intersection position of the track body 1, the drive structure 3 resets, thereby realizing track changing.
[0029] Furthermore, in the above technical solution, the conveying trolley structure 2 includes a movable frame 201, a top plate 202 on the top of the movable frame 201, a servo motor 203 in the middle of the top of the movable frame 201, an active bevel gear 204 at the output end of the servo motor 203, side frames 205 on both sides of the bottom of the movable frame 201, mounting blocks 206 on the inner side of the side frames 205, auxiliary wheels 210 rotatably connected to the bottom of the side frames 205, worm gear bodies 207 rotatably connected to both sides of the bottom of the movable frame 201, a clutch 208 inside the movable frame 201, the clutch 208 connected to the movable frame 201, and a [missing information - likely a design feature] between the two worm gear bodies 207. There is a connecting shaft, and the outer wall of the connecting shaft is provided with a driven bevel gear 209. The driven bevel gear 209 meshes with the driving bevel gear 204. When it is necessary to transport goods through the conveying trolley structure 2, the goods are placed on the top plate 202, and then the drive wheel 305 is started. The drive wheel 305 moves on both sides of the outer wall of the track body 1, so that the drive structure 3 drives the conveying trolley structure 2 to move on the top of the track body 1. When it is necessary to change tracks, the clutch 208 that needs to be separated from the track body 1 is closed according to the direction of track change, and the servo motor 203 is started. The servo motor 203 drives the driving bevel gear 204 to rotate, the driving bevel gear 204 drives the worm gear body 207 to rotate, and the worm gear body 207 drives the drive structure 3 to rotate.
[0030] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
