Description

Technical Field

[0001] This utility model relates to the field of warehousing and transportation technology, specifically a gantry-type intelligent rail stacker crane. Background Technology

[0002] A gantry stacker crane is an automated material handling system used in automated warehouses. It typically features a gantry-style frame structure, consisting of columns, beams, a lifting mechanism, a traveling mechanism, and a loading platform. This structure allows for a large span and height, enabling flexible movement and retrieval of goods within the warehouse. Its working principle involves the control system issuing commands to the traveling mechanism to move along a track to a designated position, the lifting mechanism raising and lowering the loading platform to the required height, and then the forks and other devices for loading and unloading the goods.

[0003] Currently, existing loading platforms typically use hydraulic rods or lead screws for vertical lifting. However, hydraulic rods have limited extension length, making it difficult to directly drive the platform for large lifting strokes. For larger lifting strokes, lead screw drives offer advantages over hydraulic rods. However, lead screw lifting relies on a motor to rotate the screw, converting rotational motion into linear motion, resulting in slow lifting speeds and reduced handling efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a gantry-type intelligent stacker crane to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A gantry-type intelligent rail stacker includes two parallel columns, a truss between the two columns, a lateral moving component on the truss, and the lateral moving component includes a drag chain mounted on the truss and a guide assembly connected to the drag chain. A vertical moving component is installed on the guide assembly and connected to a lifting platform. A lever mechanism is installed on the guide assembly. One end of the lever mechanism is controlled by a drive component located on the guide assembly, and the other end is connected to the vertical moving component to change the lifting stroke of the lifting platform.

[0006] As described above, the gantry-type intelligent stacker crane includes symmetrically arranged guide rods, with both ends of the guide rods fixed to the truss. Slide plates are slidably arranged on the guide rods, and the movable ends of the drag chain are fixed to the slide plates. A connecting plate with a U-shaped structure is fixed between the two slide plates.

[0007] As described above, the gantry-type intelligent stacker crane includes symmetrically arranged limiting plates, which are fixed to the connecting plate. A limiting groove is formed on the limiting plate, and a second slider is slidably arranged in the limiting groove. A second protrusion is fixedly arranged on the second slider, and a lifting frame is fixedly connected to the end of the second protrusion away from the second slider. The lifting frame is fixed to the lifting platform.

[0008] As described above, the gantry-type intelligent stacker crane has a support plate fixedly installed on the connecting plate, which can support the lever mechanism.

[0009] As described above, the gantry-type intelligent stacker crane includes a lever mechanism. The hinge shaft of the lever is rotatably mounted on the receiving plate. A first groove and a second groove are formed at both ends of the lever. A first slider is slidably disposed in the first groove. The second protrusion can penetrate the second groove and is slidably adapted to the second groove.

[0010] As described above, the gantry-type intelligent stacker crane includes an electric telescopic rod fixedly installed on the slide plate. The movable end of the electric telescopic rod is provided with a connecting hoop, and a first protrusion fixed to the first slide plate is rotatably connected to the connecting hoop.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By activating the drive mechanism, it pushes one end of the lever mechanism. As the lever balances, the other end of the lever mechanism, away from the drive mechanism, tilts up and presses against the vertical moving part. This allows the lifting platform to rise and fall in the height direction as the lever mechanism deflects. Through the cooperation of the drive mechanism and the lever mechanism, the lifting platform can perform lifting and falling actions in the height direction. At the same time, the lever mechanism can amplify the small stroke drive of the drive mechanism, enabling the lifting platform to complete a large displacement lifting and falling. When the position of the lifting platform is quickly adjusted, it is ensured that the lifting platform can cover different heights. Attached Figure Description

[0019] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0020] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0021] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0022] Please see Figures 1-6 In this embodiment of the utility model, a gantry-type intelligent stacker crane includes two parallel columns 1, a truss is provided between the two columns 1, a lateral moving part is provided on the truss, and the lateral moving part includes a drag chain 3 provided on the truss and a guide component connected to the drag chain 3. A vertical moving component is installed on the guide assembly and connected to the lifting platform 4. A lever mechanism is installed on the guide assembly. One end of the lever mechanism is controlled by a drive component set on the guide assembly, and the other end is connected to the vertical moving component to change the lifting stroke of the lifting platform 4.

[0023] In this embodiment, the cable chain 3 enables the lifting platform 4 to change position in the horizontal direction. In the vertical direction, by activating the drive mechanism, the drive mechanism pushes one end of the lever mechanism. According to the lever balance, the other end of the lever mechanism away from the drive mechanism tilts up and squeezes the vertical moving part, so that the lifting platform 4 can rise and fall in the vertical direction with the deflection of the lever mechanism. In this way, through the cooperation of the drive mechanism and the lever mechanism, while the lifting platform 4 performs the lifting action in the vertical direction, the lever mechanism can amplify the small stroke drive of the drive mechanism, so that the lifting platform 4 can complete a large displacement lifting and falling. When the position of the lifting platform 4 is quickly adjusted, it is ensured that the lifting platform 4 can cover different heights.

[0024] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The guiding assembly includes symmetrically arranged guide rods 2, with both ends of the guide rods 2 fixed to the truss. A slide plate 6 is slidably arranged on the guide rods 2. The movable ends of the drag chain 3 are fixed to the slide plates 6, and a connecting plate 7 with a U-shaped structure is fixed between the two slide plates 6.

[0025] In this embodiment, when the movable end of the drag chain 3 moves, it can drive the slide plate 6 to move synchronously. At this time, under the restriction of the guide rod 2, the slide plate 6 always moves in a straight line along the axis of the guide rod 2. When the slide plate 6 moves, it can change the position of the lifting platform 4 in the horizontal direction, and the displacement of the lifting platform 4 does not affect the subsequent lifting of the lifting platform 4 in the height direction. When the lifting platform 4 changes position in the height and horizontal directions, it can always maintain a balanced state.

[0026] For further solutions to this utility model, please refer to [link / reference]. Figure 5 The vertical moving component includes a limiting plate 8, which is fixed to the connecting plate 7. A limiting groove 801 is formed on the limiting plate 8. A second slider 15 is slidably disposed in the limiting groove 801. A second protrusion 14 is fixedly disposed on the second slider 15. A lifting frame 5 is fixedly connected to one end of the second protrusion 14 away from the second slider 15. The lifting frame 5 is fixed to the lifting platform 4.

[0027] It should be noted that: at least one set of strip grooves are formed on the side wall of the limiting groove 801, and a strip block is provided on the second slider 15 to slide in cooperation with the strip groove. Under the restriction of the strip groove and the strip block, the second slider 15 and the limiting plate 8 are slidably connected, and the second slider 15 is prevented from disengaging from the limiting plate 8 during the sliding process.

[0028] Preferably, a support plate 10 is fixedly installed on the connecting plate 7, and the support plate 10 can support the lever mechanism.

[0029] For further solutions to this utility model, please refer to [link / reference]. Figure 5 and Figure 6 The lever mechanism includes a connecting rod 11, the hinge shaft of the connecting rod 11 is rotatably mounted on the receiving plate 10, and the two ends of the connecting rod 11 are respectively formed with a first sliding groove 1101 and a second sliding groove 1102. A first slider 12 is slidably disposed in the first sliding groove 1101, and the second protrusion 14 can pass through the second sliding groove 1102 and slide and adapt to the second sliding groove 1102.

[0030] The driving component includes an electric telescopic rod 9 fixedly installed on the slide plate 6. The movable end of the electric telescopic rod 9 is provided with a connecting hoop, and a first protrusion 13 fixed to the first slider 12 is rotatably connected to the connecting hoop.

[0031] In this embodiment, when the lifting platform 4 is raised or lowered in the height direction, the electric telescopic rod 9 is activated. The movable rod of the electric telescopic rod 9 extends, and at this time, the movable rod of the electric telescopic rod 9 applies a thrust to one end of the connecting rod 11, causing the connecting rod 11 to deflect around the hinge axis. The position of the hinge axis determines the displacement stroke of the two ends of the connecting rod 11. The displacement stroke of the connecting rod 11 at the end closer to the hinge axis is small, and the displacement stroke of the connecting rod 11 at the end farther from the hinge axis is large. This amplifies the short stroke of the movable rod to the long stroke required by the lifting platform 4. Only a small extension and retraction of the electric telescopic rod 9 is needed to drive the lifting platform 4 to complete the full stroke of the lifting, reducing the dependence on the long stroke movable rod.

[0032] Specifically, when the movable rod is driven, the first protrusion 13 is squeezed, causing the connecting rod 11 to deflect. The first slider 12 slides relative to the first slide groove 1101. At this time, when the other end of the connecting rod 11 deflects, it squeezes the second protrusion 14. Due to the restriction of the limiting groove 801, when the second protrusion 14 rises along the length direction of the limiting groove 801, the second protrusion 14 moves relative to the connecting rod 11. The position of the second protrusion 14 in the second slide groove 1102 changes, ensuring that when the connecting rod 11 deflects, the movement trajectory of the second protrusion 14 is always straight, so as to maintain balance and stability when the lifting platform 4 performs lifting work.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
