Description

Technical Field

[0001] This utility model belongs to the technical field of logistics and warehousing equipment, specifically relating to a stacking fork for a three-dimensional warehouse. Background Technology

[0002] Currently, traditional automated warehouses (AS / RS) commonly use fixed stacking forks, which typically consist of a set of rigid fork arms with a fixed length. Fixed forks rely on the entire stacker crane for positioning, resulting in long travel distances, high energy consumption, and susceptibility to positioning inaccuracies due to accumulated errors. To enable the stacker crane to move smoothly back and forth to pick up and place goods, sufficient space must be reserved between the racks in the AS / RS. However, this reserved space occupies a significant proportion of the overall warehouse space, leading to substantial wasted storage space and significantly reducing the effective utilization rate of the AS / RS space.

[0003] Therefore, in order to solve the above problems, it is necessary to design a stacking fork for automated warehouses. Utility Model Content

[0004] The purpose of this invention is to provide a stacking forklift for automated warehouses to solve the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a stacking forklift for automated warehouses, comprising:

[0006] Base, top plate, and drive assembly; among which

[0007] The upper plate is mounted on the base and is slidably connected to the base; and

[0008] The drive assembly is adapted to drive the upper plate to slide on the base.

[0009] Furthermore, a pair of first guide rails are provided on the top of the base;

[0010] The bottom of the upper plate is provided with a pair of first sliders; wherein

[0011] The two first sliders are slidably connected to the corresponding first guide rails; and

[0017] Furthermore, limiting plates are provided on both sides of the base;

[0018] The drive assembly includes: a lead screw connected to the bearings of the two limiting plates and a threaded sleeve sleeved on the lead screw; wherein

[0019] The lead screw is threadedly connected to the threaded sleeve.

[0020] The threaded sleeve is connected to the bottom of the upper plate; and

[0021] The lead screw is adapted to drive the threaded sleeve to move when it rotates, and the threaded sleeve drives the upper plate to move.

[0022] Furthermore, the drive assembly also includes: a reducer connected to one end of the lead screw and a motor connected to the reducer; wherein

[0023] The speed reducer is fixed on any limiting plate; and

[0024] The motor is suitable for driving the lead screw to rotate via a speed reducer.

[0025] Furthermore, at least two guide rods are provided between the two limiting plates;

[0026] Both guide rods are fitted with connecting blocks; wherein

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0042] like Figures 1 to 3 As shown, this embodiment provides a stacking forklift for an automated warehouse, including:

[0043] The system comprises a base 1, an upper plate 2, and a drive assembly 3; wherein the upper plate 2 is disposed on the base 1 and is slidably connected to the base 1; and the drive assembly 3 is adapted to drive the upper plate 2 to slide on the base 1; wherein the base 1 is adapted to fix the stacker crane on the loading platform; and wherein the upper plate 2 is provided with a rubber pad to increase the friction between the upper plate 2 and the goods and prevent the pallet from slipping off.

[0044] In this embodiment, when the stacker crane needs to pick up or place goods, the drive component 3 drives the upper plate 2 to slide on the base 1. By adjusting the sliding distance of the upper plate 2, the effective length of the forks is changed. By adjusting the length of the forks, the number of times the stacker crane moves as a whole is reduced, thereby reducing the need for reserved space between shelves, greatly improving the space utilization of the automated warehouse, and increasing the storage capacity.

[0045] The base 1 has a pair of first guide rails 4 on its top; the upper plate 2 has a pair of first sliders 5 on its bottom; the two first sliders 5 are slidably connected to the corresponding first guide rails 4; and the first sliders 5 are adapted to slide on the first guide rails 4; the cooperation of the first guide rails 4 and the first sliders 5 provides high-precision guidance for the sliding of the upper plate 2, ensuring the stability of the forks during extension and retraction; the first guide rails 4 and the first sliders 5 are, but not limited to, dovetail-shaped, to ensure the tipping effect of the upper plate 2 when carrying goods.

[0046] The bottom of the upper plate 2 is provided with a pair of second guide rails 6; the top of the base 1 is provided with a pair of second sliders 7; wherein the two second sliders 7 are slidably connected to the corresponding second guide rails 6; and the second guide rails 6 are adapted to slide on the corresponding second sliders 7; wherein by setting the second guide rails 6 and the second sliders 7, the sliding of the upper plate 2 is guided, and at the same time, in cooperation with the first guide rails 4 and the first sliders 5, the upper plate 2 is supported at multiple points, so that the upper plate 2 is more stable when supporting goods.

[0047] The base 1 is provided with limiting plates 8 on both sides; the driving assembly 3 includes: a lead screw 301 that is bearing-connected to the two limiting plates 8 and a threaded sleeve 302 sleeved on the lead screw 301; wherein the lead screw 301 and the threaded sleeve 302 are threadedly connected; the threaded sleeve 302 is connected to the bottom of the upper plate 2; and the lead screw 301 is adapted to drive the threaded sleeve 302 to move when rotating, and the threaded sleeve 302 drives the upper plate 2 to move; by setting the limiting plates 8, the effect of supporting the lead screw 301 is achieved.

[0048] The drive assembly 3 further includes: a reducer 303 connected to one end of the lead screw 301 and a motor 304 connected to the reducer 303; wherein the reducer 303 is fixed on any limiting plate 8; and the motor 304 is adapted to drive the lead screw 301 to rotate through the reducer 303.

[0049] In this embodiment, when the motor 304 rotates forward, the motor 304 drives the lead screw 301 to rotate through the reducer 303. Since the lead screw 301 is threadedly connected to the threaded sleeve 302, the rotation of the lead screw 301 will drive the threaded sleeve 302 to move along its axial direction. The movement of the threaded sleeve 302 will drive the upper plate 2 to move, thereby realizing the extension of the forks. When the motor 304 rotates in reverse, the forks will retract.

[0050] At least two guide rods 9 are provided between the two limiting plates 8; each of the two guide rods 9 is fitted with a connecting block 10; wherein the connecting block 10 is slidably connected to the guide rod 9; and the two connecting blocks 10 are connected to the bottom of the upper plate 2; by setting the guide rods 9 and the connecting blocks 10, and the connecting blocks 10 being slidably connected to the guide rods 9, the weight of the upper plate 2 and the goods it carries is distributed to the guide rods 9 without affecting the movement of the upper plate 2. With the support of the first guide rail 4 and the first slider 5, and the support of the second guide rail 6 and the second slider 7, the stress on individual components is reduced, the service life of each component is extended, and the load-bearing capacity of the forks is also improved.
