Description

Technical Field

[0001] The utility model relates to the technical field of warehousing and logistics equipment, in particular to a semi-electric pallet stacker with adjustable forks. Background Art

[0002] Semi-electric pallet stackers with adjustable forks operate through a combination of electric drive and manual operation. The electric drive system provides the primary power, enabling the stacker to quickly move short distances and lift cargo, while the manual operation system allows for precise control and adjustment. To move cargo, the operator places the cargo on the forks, which are then raised by the electric drive system. The manual operation system then moves the stacker to the desired location and places the cargo. Stacking is similar: the forks are raised electrically, the cargo is placed on them, and then the stacker is manually moved to the designated location for placement.

[0003] The electric pallet stacker consists of a chassis, a gantry, forks and a power system. The chassis is the foundation of the entire stacker and plays a stabilizing and supporting role. The height-adjustable gantry consists of an outer gantry and an inner gantry. The outer gantry is fixed, and the inner gantry can be raised and lowered along the outer gantry to provide guidance and support for the lifting of goods, so that the goods can reach different heights. The forks can be adjusted according to the size of the pallet, etc., to facilitate forking of goods. The power system combines electric drive and manual operation parts. The electric drive is used to lift goods and move short distances. The manual operation facilitates precise control of the movement of the stacker and the adjustment of the fork height.

[0004] In the existing technology, some adjustable forks have a relatively cumbersome method of adjusting the spacing between some forks. The traditional manual adjustment method requires the operator to use tools. Some devices that rely on simple sliding guide rails to adjust the spacing between the forks have difficulty in achieving a very precise fitting clearance between the guide rails and the forks. Therefore, a semi-electric pallet stacker with adjustable forks is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a semi-electric pallet stacker with adjustable forks, which aims to improve the problem that the fork spacing adjustment method in the prior art is relatively cumbersome.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] As a further description of the above technical solution:

[0009] The fork telescopic assembly includes a fixed fork, the fixed fork is fixedly connected to the outer wall of the fork fixing plate, the inner wall of the fixed fork is fixedly connected to a locking block, the inner wall of the fixed fork is slidably connected to a sliding plate, the driving end of the motor on the inner wall of the sliding plate is fixedly connected to a control wheel, and the outer wall of the sliding plate is slidably connected to a rigid chain;

[0010] As a further description of the above technical solution:

[0011] The outer wall of the control wheel is coupled to the inner wall of the rigid chain, and the outer wall of the locking block is fixedly connected to the inner wall of the rigid chain;

[0012] As a further description of the above technical solution:

[0013] The outer wall of the rigid chain is fixedly connected to a connecting block, and the top of the connecting block is fixedly connected to a telescopic fork;

[0014] As a further description of the above technical solution:

[0015] The telescopic fork is slidably connected to the top of the fixed fork, and the fixed fork is slidably connected to the bottom of the pitch variable plate;

[0016] As a further description of the above technical solution:

[0017] The outer wall of the bidirectional threaded rod is fixedly connected to the driving end of the driving motor, and the inner wall of the fork fixing plate is slidably connected to the outer wall of the variable distance slide rail;

[0018] As a further description of the above technical solution:

[0019] The inner wall of the gantry is provided with a height adjuster, and the other end of the height adjuster is fixedly connected to the top of the pitch variable plate;

[0020] As a further description of the above technical solution:

[0021] The outer wall of the gantry is fixedly connected to the vehicle body, and the outer wall of the vehicle body is fixedly connected to the pull rod.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, the drive motor is started, and the drive motor drives the bidirectional threaded rod, which drives the fork fixing plate to move toward or oppositely, so as to adjust the spacing between the forks. When the required spacing is adjusted, the drive motor stops and drives the bidirectional threaded rod to rotate, so as to reduce or increase the spacing between the forks, so that the forks can adapt to goods of different lengths and widths.

[0024] 2. In the present invention, the motor drives the rotating column to rotate, and the rotating column drives the rigid chain to rotate. Due to the presence of the locking block, the locking block will limit the rotation of the rigid chain, and the rigid chain will move the rotating column and the sliding plate toward the outside of the fixed fork. Because the outside of the rigid chain is connected to the telescopic fork through the connecting block, the rigid chain will move forward with the connecting block and the telescopic fork, thereby completing the telescopic range extension of the fork.

[0025] In summary, the utility model has the advantages of being able to adapt to different sizes of goods, and being able to load and grab goods at a longer distance through telescopic means. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example 2

[0036] Reference Figure 2 、 Figure 3 and Figure 4 The fork telescopic assembly includes a fixed fork 9, which is fixedly connected to the outer wall of the fork fixing plate 1. The fixed fork 9 is the basic part of the fork structure and plays a role in supporting and positioning. The inner wall of the fixed fork 9 is fixedly connected with a locking block 10. The locking block 10 is mainly used to limit and constrain the subsequent fork telescopic process. The inner wall of the fixed fork 9 is slidably connected with a sliding plate 11. The sliding plate 11 can slide on the inner wall of the fixed fork 9 to achieve the change of the fork length. The driving end of the motor on the inner wall of the sliding plate 11 is fixedly connected with the control wheel 7, which drives the control wheel 7 to rotate by the motor to drive other related components to move.

[0037] The outer wall of the sliding plate 11 is slidably connected with a rigid chain 12, and the rigid chain 12 is used to realize the telescopic transmission of the fork.

[0038] Working steps

[0039] When the spacing between the forks needs to be adjusted, the drive motor 4 is started, and the drive motor 4 drives the bidirectional threaded rod 6, which drives the fork fixing plate 1 to move toward or oppositely, so as to adjust the spacing between the forks. When the required spacing is adjusted, the drive motor 4 stops driving the bidirectional threaded rod 6 to rotate, so as to reduce or increase the spacing between the forks, so that the forks can adapt to goods of different lengths and widths.

[0040] When the length of the fork needs to be increased, the motor inside the sliding plate 11 is started, and the motor drives the control wheel 7 to rotate, and the control wheel 7 drives the rigid chain 12 to rotate. Due to the presence of the locking block 10, the locking block 10 will limit the rotation of the rigid chain 12, and the rigid chain 12 will move the control wheel 7 and the sliding plate 11 toward the outside of the fixed fork 9. Because the outside of the rigid chain 12 is connected to the telescopic fork 14 through the connecting block 13, the rigid chain 12 will move forward with the connecting block 13 and the telescopic fork 14, thereby completing the telescopic range extension of the fork.

[0041] When the spacing and length of the forks are adjusted to match the goods to be stacked, the goods are placed on the forks, and then the pull rod 17 can be used to pull the goods to the place where they need to be stacked and unload the goods. If the height needs to be adjusted, the height adjuster 16 can be driven to send the goods to the corresponding height.
