[0046] The following is an explanation of the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0047] See also Figures 1 to 5 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the restrictive conditions for the implementation of the utility model, so they have no substantive technical significance. Any modification of the structure, change in the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model.

[0048] See also Figures 1 to 5The utility model discloses a track adjustment mechanism and a transport vehicle, which can be used to improve the problem that the existing transport vehicle is prone to position deviation when moving through the track 100, resulting in inaccurate positioning of the transport vehicle during use. Specifically, the transport vehicle moves through the track 100, and the track adjustment mechanism is connected to the vehicle on the track 100. Therefore, the track adjustment mechanism can be used to achieve adaptive adjustment of the position of the transport vehicle during movement.

[0049] Specifically, the adjustment mechanism of the track may include two sets of parallel tracks 100 and a moving assembly 200, and the moving assembly 200 is connected to the track 100. At the same time, for the conveying vehicle, it may include the adjustment mechanism of the track, the connecting assembly 300 and the lifting assembly 400. Among them, the connecting assembly 300 is connected to the adjustment mechanism of the track, and the lifting assembly 400 is connected to the connecting assembly 300. It can be understood that the lifting assembly 400 is also connected to a material handling mechanism, and the material is fixedly clamped by the material handling mechanism. At the same time, the lifting assembly 400 can be used to drive the material handling mechanism to move in the vertical direction, and the moving assembly 200 can be used to realize the reverse movement of the connecting assembly 300 and the lifting assembly 400 along the track 100. Therefore, in one embodiment, the track 100 direction and the vertical direction can be allowed to be vertically arranged.

[0050] See also Figures 1 to 5 In one embodiment, the two tracks 100 are symmetrically arranged, and a connecting surface 101 is provided on the track 100. It is understandable that the moving component 200 is connected to the track 100 via the connecting surface 101. It should be noted that the two connecting surfaces 101 are arranged at an angle, and the two connecting surfaces 101 are arranged opposite to each other. For example, the angle between the two connecting surfaces 101 is 160° to 180°. Preferably, the angle between the two connecting surfaces 101 can be allowed to be between 175 and 180 degrees. For example, in one embodiment, the angle between the two connecting surfaces 101 is 178 degrees. It should be noted that the two connecting surfaces 101 are symmetrically arranged, and the connecting surface 101 is located on the inner side of the two tracks 100.

[0051] Furthermore, a moving component 200 is connected to the track 100 , and the moving component 200 is allowed to move along the track 100 .

[0052] See also Figures 1 to 5In one embodiment, the moving assembly 200 may include two sets of connecting frames 210, and the first roller 211 and the second roller 212 are rotatably arranged on the connecting frames 210. It can be understood that the first roller 211 and the second roller 212 are respectively located at the two ends of the connecting frame 210, and the main shaft 213 is also connected between the first rollers 211 located on the two connecting frames 210. Specifically, one end of the main shaft 213 is fixedly connected to the first roller 211 on one side of the connecting frame 210, and the other end of the main shaft 213 is fixedly connected to the first roller 211 on the other side of the connecting frame 210. Therefore, the first rollers 211 on the two connecting frames 210 can be allowed to rotate synchronously.

[0053] It should be noted that a driving member 220 is also allowed to be connected to the connecting frame 210, and the driving member 220 is transmission-connected to the first roller 211. Therefore, the driving member 220 can be used to drive the first roller 211 to rotate. The driving member 220 can be a servo motor, but it is not limited to it. The driving member 220 can be determined according to actual needs. In addition, the servo motor and the first roller 211 can be driven by a gear pair or a belt auxiliary drive, which can be determined according to actual needs.

[0054] Among them, for the first roller 211 and the second roller 212, a truncated cone structure is adopted. It can be understood that the truncated cone surface of the truncated cone structure is connected to the connecting surface 101 of the track 100. Therefore, the center angle of the truncated cone is the same as the horizontal angle of the connecting surface 101, so that the truncated cone can be stably connected to the connecting surface 101. At the same time, in order to improve the connection effect between the truncated cone and the track 100, protective plates 2100 are fixedly connected to the sides of the first roller 211 and the second roller 212 respectively. The protective plate 2100 can effectively prevent the rollers from falling off the track 100. Among them, the first roller 211 and the second roller located on the track 100 are truncated cone structures, and the small end of the truncated cone structure is facing between the two tracks 100.

[0055] See also Figures 1 to 5 In one embodiment, the width of the first roller 211 is between 1.5 and 2 times the width of the track 100, and the width of the second roller 212 is between 1.1 and 1.2 times the width of the track 100. Therefore, when the moving assembly 200 moves on the track 100, the first roller 211 can provide power. At the same time, through the inclination setting between the first roller 211 and the second roller 212 and the connecting surface 101 of the track 100, the first rollers 211 on the two tracks 100 can drive the corresponding connecting frames 210 to move closer to the middle sides of the two tracks 100. Therefore, the automatic correction effect of the device during the movement is achieved by the first rollers 211 on both sides.

[0056] At the same time, since the width of the first roller 211 is between 1.5 and 2 times the width of the track 100 , the spatial range of the device moving on the track 100 can be effectively increased. In addition, the second roller 212 can be used to improve the stability of the device during movement on the track 100 .

[0057] Specifically, in order to improve the use effect of the device in actual use, it is allowed to allow the two ends of the connecting frame 210 to be detachably connected with anti-collision blocks 230. The anti-collision blocks 230 are used to prevent the ends of the connecting frame 210 from directly colliding with external components.

[0058] See also Figures 1 to 5 In one embodiment, for the transport vehicle, its connection assembly 300 is connected to two connection frames 210. Specifically, the connection assembly 300 includes at least a side bracket 310 and a transverse bracket 320, and the side brackets and the transverse bracket 320 are fixedly connected. The side bracket 310 includes two groups, and is respectively connected to the corresponding connection frames 210 on the two rails 100. In addition, the transverse bracket 320 is located between the two side brackets 310, and the transverse bracket 320 is detachably connected to the side bracket 310.

[0059] At the same time, in order to improve the connection effect between the side bracket 310 and the transverse bracket 320, a support column 330 is also connected between the side bracket 310 and the transverse bracket 320. Multiple groups of support columns 330 can be set to improve the stability of the connection between the side bracket 310 and the transverse bracket 320 through the support columns 330.

[0060] See also Figures 1 to 5 In one embodiment, the lifting assembly 400 is located on the connecting assembly 300, and a material fixing mechanism 430 for fixing and clamping the material is also connected to the lifting assembly 400. It can be understood that the material fixing mechanism 430 can be used to fix and clamp the material.

[0061] Specifically, the lifting assembly 400 may include a movable frame 410 and a winding mechanism 420 , and the movable frame 410 is transmission-connected to the winding mechanism 420 .

[0062] The side bracket 310 may be fixedly connected with a vertical slide rail, and the movable frame 410 is slidably connected to the slide rail. At the same time, the material fixing mechanism 430 is fixedly connected to the movable frame 410. When the movable frame 410 slides along the slide rail, the material fixing mechanism 430 may be driven to move in the vertical direction.

[0063] Furthermore, the reeling mechanism 420 is located on the transverse bracket 320, and a plurality of reeling belts 421 are connected to the reeling mechanism 420. The ends of the reeling belts 421 are connected to the movable frame 410, and when the reeling belts 421 are reeled, the position of the movable frame 410 can be adjusted.

[0064] See also Figures 1 to 5 In one embodiment, the winding mechanism 420 may include a mounting seat 423, a winding motor 424 and a winding wheel 425. The mounting seat 423 is fixedly connected to the transverse bracket 320, and the winding motor 424 is fixedly connected to the mounting seat 423. The winding wheel 425 includes two groups, and the two groups of winding wheels 425 are respectively located on both sides of the mounting seat 423. It can be understood that the winding wheel 425 and the winding motor 424 are connected by transmission. The specific transmission method can be determined according to actual needs. For example, the winding motor 424 and the winding wheel 425 can be driven by a gear pair, a bevel gear pair, or a worm gear.

[0065] Two groups of winding belts 421 are symmetrically connected to the winding wheel 425, and the two groups of winding belts 421 are centrally symmetrically arranged along the center of the winding. It can be understood that the two groups of winding belts 421 on the winding wheel 425 are respectively fixedly connected to the two ends of the movable frame 410. Therefore, when the winding wheel 425 is winding, the winding belts 421 on both sides can effectively improve the stability of the movable frame 410 during the sliding process.

[0066] See also Figures 1 to 5 In one embodiment, a guide wheel 422 may be provided in the moving path of the winding belt 421, and the winding belt 421 and the guide wheel 422 are connected. Therefore, when the winding belt 421 is winding or unwinding, the guide wheel 422 may be driven to rotate by the friction between the winding belt 421 and the guide wheel 422. At the same time, in order to improve the connection effect between the guide wheel 422 and the winding belt 421, baffles 4220 may be fixedly connected to both sides of the guide wheel 422. The baffles 4220 may prevent the winding belt 421 from slipping out of the guide wheel 422.

[0067] It should be noted that the middle part of the side of the guide wheel 422 is convex. The guide wheel 422 has an axis, and the distance from the outer peripheral surface of the guide wheel 422 to the axis decreases from the middle to both sides. Specifically, the convex shape of the middle part of the side of the guide wheel 422 indicates that the side of the guide wheel 422 is an arc surface. By setting the side of the guide wheel 422 as an arc surface structure, the winding belt 421 can be prevented from swinging on the guide wheel 422, thereby ensuring that the winding belt 421 is always in the center line position during the winding process.

[0068] In summary, the utility model discloses a track adjustment mechanism and a conveying vehicle, wherein the track adjustment mechanism is that when the moving assembly 200 moves on the track 100, the first roller 211 can provide power. At the same time, the inclination angle between the first roller 211 and the second roller 212 and the connecting surface 101 of the track 100 is set, and the first rollers 211 on the two tracks 100 can drive the corresponding connecting frames 210 to move closer to the middle sides of the two tracks 100, so as to achieve the automatic correction effect of the device during the movement process.

[0069] Furthermore, when the conveying vehicle is in use, the convex shape in the middle of the side of the guide wheel 422 can prevent the winding belt 421 from swinging on the guide wheel 422, thereby ensuring that the winding belt 421 is always in the center line position during the winding process.

[0070] Therefore, the problem that the existing transport vehicle is prone to position deviation when moving through the track 100, resulting in inaccurate positioning of the transport vehicle during use, can be effectively improved.

[0071] Therefore, the utility model effectively overcomes some practical problems in the prior art and has high utilization value and use significance.

[0072] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
