[0057] In order to enable those skilled in the art of this technology to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0058] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "circumferential", "radial", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this utility model.

[0059] In addition, 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 quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more unless otherwise specifically defined.

[0060] At least one embodiment of the present utility model provides a conveying unit, as Figures 1-4 shown, the conveying unit 10 includes a roller assembly 1, a first roller fixing frame 2, a second roller fixing frame 3, and a transmission belt 5; wherein, the roller assembly 1 includes a plurality of rollers 11 arranged side by side, and the roller assembly 1 is used for conveying goods; the first roller fixing frame 2 and the second roller fixing frame 3 are respectively located on both sides of the roller assembly 1 and are used for supporting the roller assembly 1, as Figure 5 shown, both the first roller fixing frame 2 and the second roller fixing frame 3 are provided with clamping grooves 4, and both ends of the roller 11 are respectively snapped into the first roller fixing frame 2 and the second roller fixing frame 3 through the clamping grooves 4; further, as Figure 6 shown, the first ends of two adjacent rollers 11 are connected by a transmission belt 5.

[0061] Since the first ends of two adjacent rollers 11 are connected by a transmission belt 5, the rollers 11 only need to be directly placed or fixed with extremely simple components, solving the technical problem of inconvenient installation and replacement, avoiding the use of rollers with axially telescopic shafts, reducing the use of fixing parts and fasteners at the same time, making the overall equipment cost reduced, and enabling the rollers to be installed without screws and without the use of fasteners.

[0062] Optionally, as Figure 5 shown, the first roller fixing frame 2 (or the second roller fixing frame 3) is provided with a plurality of clamping grooves 4, and the clamping grooves 4 are perpendicular to the axial direction of the roller 11 to facilitate snapping both ends of the roller 11 into the first roller fixing frame 2 and the second roller fixing frame 3 through the clamping grooves 4 during installation. It should be noted that the clamping grooves 4 can be arranged at equal intervals, and the number of clamping grooves 4 provided on the first roller fixing frame 2 (or the second roller fixing frame 3) is the same as the number of rollers 11, so that both ends of each roller 11 are respectively snapped into the corresponding clamping grooves 4.

[0063] In some embodiments of the present utility model, as Figure 6As shown, the drive belt 5 is a multi-wedge belt. A connecting groove 12 is provided on the outer surface of the first end of the roller 11. The drive belt 5 is snap-connected to the first end of the roller 11 through the connecting groove 12. Since the first ends of two adjacent rollers 11 need to be connected by the drive belt 5, in order to increase the friction between the drive belt 5 and the roller 11 and prevent the two from slipping during transmission, a connecting groove 12 is provided on the outer surface of the first end of the roller 11. The drive belt 5 is wound around the connecting groove 12. When one of the rollers 11 rotates, it drives the other roller to rotate through the drive belt 5, so as to achieve the purpose of transporting goods.

[0064] As Figure 3 shown, the roller assembly 1 includes at least one driving roller 111 and a plurality of driven rollers 112 arranged side by side. The driving roller 111 can rotate and drives the driven rollers 112 to rotate through the drive belt 5. Among them, the number of driving rollers 111 can be one or more. The driving roller 111 is equipped with a cable and can rotate after being powered on, which is used to provide conveying power. The driven roller 112 has no cable and is driven to rotate by the driving roller 111. The driven roller 112 and the driving roller 111 are jointly used to support and transport goods. Optionally, the driving roller 111 can be installed at any position of the roller assembly 1, such as on one side or in the middle of the roller assembly 1. The driving roller 111 and the driven roller 112 are connected by a plurality of drive belts 5. The drive belts 5 are wound around the first ends of the driving roller 111 and the driven roller 112. One drive belt 5 is installed between every two adjacent rollers 11 (driving roller 111 or driven roller 112), so that all the rollers 11 can rotate synchronously.

[0065] In some other embodiments of the present invention, as Figure 4 shown, a limiting rope 6 is provided on the second roller fixing frame 3. The limiting rope 6 is located above the shaft head of the second end of the roller 11 and is used to limit the upward movement of the shaft head of the second end of the roller 11. That is to say, the side without the drive belt 5 installed restricts the upward movement of the shaft head of the second end of the roller 11 through the limiting rope 6. Optionally, the limiting rope 6 can be made of steel material, that is, a steel wire rope.

[0066] As Figure 7 shown, both ends of the limiting rope 6 are wound around the first screw 61 and tightened to the second roller fixing frame 3 by a nut 62. Just tighten the limiting rope 6 and wind it around the first screw 61, and press it tightly with the nut 62. The installation position of the limiting rope 6 just presses the shaft head of the roller 11, which restricts the upward movement tendency of the roller 11 to a certain extent and prevents the roller 11 from coming off when the downward acceleration is too large. Both ends of the limiting rope 6 are fixed to both ends of the second roller fixing frame 3 and will not be blocked, and the operation is unobstructed.

[0067] As Figure 12As shown in the figure, it is used to illustrate the principle that the limit rope 6 only needs to be installed on the second drum fixing bracket 3 on the side without the conveyor belt 5. On the side of the conveyor belt 5, every two drums 11 are wound with the conveyor belt 5. The conveyor belt 5 has tightened the two drums 11 together, and the frictional force between the conveyor belt 5 and the card slot 4 of the first drum fixing bracket 2 can prevent the drums from slipping out upwards. When the drum 11 moves upwards, it does not rotate around the adjacent drum 11 in a circular motion, but moves vertically upwards. For example, when it moves upwards by L1, the center distance between the two drums is equivalent to L2 shown in the figure, and L2 > R, which is equivalent to the conveyor belt 5 being stretched. In fact, the conveyor belt 5 is internally equipped with metal steel wires and will not be stretched. Therefore, under the restriction of the conveyor belt 5, the drum 11 will not move upwards.

[0068] It should be noted that if the conveying unit 10 is used as the conveying component of the hoist and has a large acceleration during the up and down movement, the limit rope 6 is used to simply fix the drum 11. If the conveying unit 10 is used as the conveying component of an ordinary conveyor line and only conveys without lifting, there is no need to install the limit rope 6.

[0069] In some other embodiments of the present invention, as Figure 8 shown, the number of power drums 111 is one, and the power drum 111 is located on the outermost side of the drum assembly 1 to facilitate the installation of the fixing member 7 corresponding to the power drum 111.

[0070] In some other embodiments of the present invention, the conveying unit 10 further includes a fixing member 7. The fixing member 7 fixes the shaft head at the second end of the power drum 111 to the second drum fixing bracket 3. Since the power drum 111 starts and stops frequently, and there is a gap between its shaft head and the card slot 4 of the second drum fixing bracket 3, the shaft head repeatedly starts and stops in two directions in the card slot 4, has a wobbling amount, and is easily worn, resulting in a larger gap in the card slot 4, and further causing unstable operation and generating a large amount of noise. After sufficient wear, the shaft head may rotate in the card slot 4, resulting in the cable being broken. In the embodiment of the present invention, the fixing member 7 is used to fix the shaft head at the second end of the power drum 111 in the card slot 4 to prevent the shaft head from repeatedly starting and stopping in two directions in the card slot 4, thereby preventing the card slot 4 from being worn.

[0071] Optionally, as Figures 8-9 shown, the fixing member 7 includes a first fixing member 71 and a second fixing member 72. The first fixing member 71 is fixed to the second drum fixing bracket 3, and the second fixing member 72 is fixed to the first fixing member 71, thereby fixing the shaft head at the second end of the power drum 111 between the first fixing member 71 and the second fixing member 72. Optionally, as Figures 9-11As shown, a first mounting hole 76 is provided on the first fixing member 71. The second screw 75 fixes the first fixing member 71 to the second roller fixing bracket 3 through the first mounting hole 76. A second mounting hole 77 is provided on the second fixing member 72. A third screw (not shown in the figure) fixes the second fixing member 72 to the first fixing member 71 through the second mounting hole 77, thereby firmly fixing the shaft head at the second end of the power roller 111 between the first fixing member 71 and the second fixing member 72.

[0072] Optionally, as Figures 10-11 shown, a first groove 73 is provided on one side of the first fixing member 71 facing the second fixing member 72, and a second groove 74 is provided on one side of the second fixing member 72 facing the first fixing member 71. The shaft head at the second end of the power roller 111 is fixed in the first groove 73 and the second groove 74. Optionally, the shaft head of the roller 11 can be hexagonal, and the first groove 73 and the second groove 74 jointly lock the shaft head of the power roller 111 between the first fixing member 71 and the second fixing member 72.

[0073] Compared with the integrated fixing member, the fixing member 7 in the embodiment of the present invention can not only firmly fix the shaft head of the power roller 111 in the fixing member 7, but also is convenient to install. The shaft head does not need to be installed with screws, and the roller can be installed without screws.

[0074] Optionally, as Figures 1-2 shown, guide members 8 are respectively provided above the first roller fixing bracket 2 and the second roller fixing bracket 3. The guide members 8 on both sides are used to guide the goods conveyed by them to prevent the goods from falling.

[0075] When installing the roller 11, it only needs to be directly placed into the card slots 4 of the first roller fixing bracket 2 and the second roller fixing bracket 3 from top to bottom. The shaft head of the roller 11 does not need to have an elastic structure and is installed in the card slot 4 by the self-gravity of the roller 11, and the conveying unit 10 can be directly used; while the hoist has the actions of rising and falling. Therefore, in order to prevent the roller 11 from jumping up or even disengaging, the embodiment of the present invention uses a limit rope 6 to limit its position. The installation and replacement of the roller 11 are extremely simple. Except for the power roller 111, it can be installed and disassembled without tools (the limit rope 6 does not need to be removed during loading and unloading. Because the limit rope 6 has a certain flexibility, one end of the roller 11 can be inserted under the limit rope 6).

[0076] It can be seen that the conveying unit provided by the embodiment of the present invention can solve the problems of inconvenient installation and replacement. The roller only needs to be directly placed or fixed with extremely simple parts; moreover, it can avoid using a roller with a telescopic shaft head, reduce the fixing members and fasteners at the same time, and overall reduce the equipment cost; it can also make the roller installed without screws and does not need to use fasteners.

[0077] The present utility model also provides a conveying device, which includes the conveying unit described in any of the above embodiments. Optionally, as Figure 13 shown, the conveying device may be an elevator 20 or a conveying line. Since there are a frame and lifting columns around the conveying unit 10 of the elevator 20, it is relatively inconvenient to install and disassemble the drum 11. Since the conveying unit of the embodiment of the present utility model can be installed and disassembled without tools except for the power drum 111, the installation and replacement are extremely simple and not limited by the surrounding frame and lifting columns.

[0078] The above specific embodiments do not constitute a limitation on the protection scope of the present utility model. Those skilled in the art should understand that various modifications, combinations, sub - combinations and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
