Detailed Implementation

[0030] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0031] It should be noted that many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1-5 As shown, the lifting transfer trolley provided by this utility model includes a frame 100, a lifting drive assembly, a first lifting plate 200, a lifting mechanism, and a second lifting plate 300. The frame 100 is provided with an upwardly extending mounting bracket 110, and the front side of the second lifting plate 300 is provided with a cargo positioning mechanism.

[0033] The lifting drive mechanism includes a first guide rail slider assembly and a first pull rope assembly; the first guide rail slider assembly includes a first guide rail 410 and a first slider 420. The upper and lower ends of the first guide rail 410 are respectively fixed to the upper part of the frame 100 and the mounting bracket 110. The first slider 420 slides up and down along the first guide rail 410. The first lifting plate 200 is fixed to the front side of the first slider 420.

[0034] The first pull rope assembly includes a first pull rope 510, a first pulley 520, and a take-up roller 530. The first pulley 520 is fixed to the upper part of the frame 100, and the take-up roller 530 is fixed to the lower part of the frame 100. After the first pull rope 510 passes over the top of the first pulley 520, the first end is fixed to the lower part of the first lifting plate 200, and the second end is wound around the take-up roller 530.

[0035] When the take-up roller 530 rotates, the first pull rope 510 can be wound around the take-up roller 530 or a longer first pull rope 510 can be released from the take-up roller 530. The part that is not wound around the take-up roller 530 is the release length of the first pull rope.

[0036] The lifting mechanism includes a second guide rail slider assembly and a second pull rope assembly; the second guide rail slider assembly includes a second guide rail 610 and a second slider 620, the second guide rail 610 is fixed to the front side of the first lifting plate 200, the second slider 620 slides up and down along the second guide rail 610, and the second lifting plate 300 is fixed to the front side of the second slider 620.

[0037] The second pull rope assembly includes a second pull rope 710 and a second pulley 720. The second pulley 720 is fixed to the top of the first lifting plate 200. After the second pull rope 710 passes over the top of the second pulley 720, its first end is fixed to the lower part of the second lifting plate 300 and its second end is fixed to the mounting bracket 110.

[0038] When the first lifting plate 200 moves upward, it drives the second pulley 720 to move upward, which in turn lifts the middle of the second pull rope 710. Since the second end of the second pull rope 710 is fixed to the frame 100, when the middle of the second pull rope 710 is lifted upward, its second end will pull the second lifting plate 300 upward, thus changing the trolley's pushing position from... Figure 6 In the middle, (a) becomes (b). Specifically, Figure 6 (a) is a diagram showing the state when the first lifting plate 200 and the second lifting plate 300 of the transfer trolley provided by this utility model are lowered to their low positions. Figure 6 (b) is a diagram showing the state of the goods after the transfer trolley provided by this utility model has lifted them.

[0039] To specifically illustrate the superior effect of the coordinated operation of the lifting drive assembly, the first lifting plate 200, the lifting mechanism, and the second lifting plate 300 in this utility model, the applicant has... Figure 6 Image (c) also shows the working state of a conventional trolley structure without the first lifting plate 200 and the lifting mechanism, where the second lifting plate 300 is directly fixed to the first slider 420. It can be seen that in order to lift goods to the same height, the height of the guide rails in a conventional trolley is significantly increased. However, this invention, through the cooperation of the lifting drive assembly, the first lifting plate 200, the lifting mechanism, and the second lifting plate 300, reduces the height of the transfer trolley in the folded state, making it more convenient to use.

[0040] The transfer trolley provided by this utility model is applicable to Figure 7 The fruit basket 800 shown is tapered at the bottom and wider at the top, formed by welding metal rods. To secure the fruit basket, a cargo positioning mechanism includes a support claw 910 located at the bottom front of the second lifting plate 300. The support claw 910 has an arc-shaped structure and can be positioned around the lower part of the fruit basket, providing upward support.

[0041] To further position the fruit basket, the cargo positioning mechanism also includes a hook 920 located in the middle of the front side of the second lifting plate 300. The hook 920 can lift the fruit basket by hooking onto the horizontal rib on the fruit basket.

[0042] In use, the lower part of the goods is supported by the support claw 910, and the upper part is hooked by the hook 920, thus positioning the goods on the second lifting plate 300. When the drive take-up roller 530 rotates, the first pull rope 510 is wound around the take-up roller 530, and the released length of the first pull rope 510 shortens, pulling the first lifting plate 200 upward. The upward movement of the first lifting plate 200 simultaneously moves the first pulley 520 at its top upward. The upward movement of the first pulley 520 lifts the middle part of the second pull rope 710. Since the second end of the second pull rope 710 is fixed to the frame 100, the lifting of the second pull rope 710 causes the first end of the second pull rope 710 to move upward, thereby driving the second lifting plate 300 upward. This causes the goods on the second lifting plate 300 to move upward, away from their original support surface. Then, push or pull the trolley to the desired position, and manipulate the take-up roller 530 to reverse, so that the release length of the first pull rope 510 increases. As the release length of the first pull rope 510 increases, the first lifting plate 200 and the second lifting plate 300 gradually move downward until the goods are placed on the new support surface, and the goods are separated from the hook 920.

[0043] like Figure 1 As shown, in one embodiment, the vertical position of the hook 920 is adjustable. Specifically, the hook 920 is fixed to the second lifting plate 300 by a first bolt 921, and the second lifting plate 300 has a vertical elongated hole 922 through which the first bolt 921 passes.

[0044] like Figure 8 , Figure 9 As shown, in another embodiment, the horizontal and vertical positions of the hook 920 are adjustable, and multiple hooks can be provided. Specifically, the hook 920 is mounted on the connecting plate 924 by a second bolt 923. The connecting plate 924 has a horizontal elongated hole 925 through which the second bolt 923 passes. The number of hooks 920 is one or more. The connecting plate 924 is mounted on the second lifting plate 300 by a first bolt 921. The second lifting plate 300 has a vertical elongated hole 922 through which the first bolt 921 passes.

[0045] After loosening the first bolt 921 and the second bolt 923, the position of the hook 920 can be adjusted up and down and left and right. After adjustment, tighten the nut to fix the bolt. The position of the hook is adjustable, which can easily match different sizes of fruit baskets.

[0046] In actual processing, a hook can be welded to the outer end of the second bolt, or the outer end of the second bolt can be bent into a hook shape.

[0047] Furthermore, in order to facilitate observation of the trolley's operation, especially the operation when the hook catches the fruit basket, it is preferable to have a hollow area 140 in the middle of the mounting frame 110; and to have an observation hole 310 that penetrates the surface of the second lifting plate 300 above the cargo positioning mechanism.

[0048] Understandably, the frame 100 provided by this utility model has wheels 120 on the left and right sides of its bottom, and a handlebar 130 is provided on the upper rear side of the mounting bracket 110. The cart can be moved by pushing the handlebar 130 forward.

[0049] Typically, the take-up roller 530 is connected to the output shaft of the motor, and the motor is self-locking, which allows the goods to be held at the appropriate height after being lifted.

[0050] like Figure 5 As shown, there are two first guide rail slider assemblies. The first sliders 420 of the two first guide rail slider assemblies are connected to each other through a connecting plate, and the connecting plate is then connected to the first lifting plate 200.

[0051] The function of the first guide rail slider assembly is to smoothly raise and lower the first lifting plate 200, and the function of the second guide rail slider assembly is to smoothly raise and lower the second lifting plate 300. The guide rail slider assemblies adopt conventional structures in existing technology. For example, the first guide rail slider assembly uses a cylindrical guide rail, and the second guide rail slider assembly uses a square column guide rail. Ball bearings are installed inside the sliders.

[0052] It should be noted that the first slider 420 is fixedly connected to the first lifting plate 200, and when the first end of the first pull rope 510 is fixed to the first slider 420, it should also fall within the protection scope of this utility model. The second slider 620 is fixedly connected to the second lifting plate 300, and when the first end of the second pull rope 710 is fixed to the second slider 620, it should also fall within the protection scope of this utility model.

[0053] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", 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.

[0054] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
