Description

Technical Field

[0001] The utility model relates to the technical field of special attachments for industrial vehicle forklifts, and particularly relates to a forklift rotary fork that can be clamped in multiple directions. Background Art

[0002] A forklift attachment, also known as a multi-device, is a special accessory installed on a forklift, used to expand the functionality and application range of the forklift, enabling the forklift to more efficiently and safely complete diverse handling, loading, unloading, and stacking tasks. The forklift attachment includes a rotary clamp, which usually controls the opening and closing and rotation actions through a hydraulic system, and can achieve 360-degree free rotation of the goods and lock the goods at a specific angle.

[0003] The main types of existing rotary clamps are soft-pack clamping rotators, barrel clamping rotators, paper roll clamping rotators, and general rotators. They usually can only provide clamping forces in opposite directions to the goods, that is, they carry the goods by clamping two opposite sides of the goods. However, for relatively heavy goods, if there is no structure for limiting the fixture on the two sides used for clamping, the goods may slip out of the rotary clamp during handling, causing accidents; and for goods stacked in stacks, they are prone to falling during handling or the goods are scattered during stacking, reducing the palletizing efficiency.

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "inner", "outer", "upper", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship when the product of the present utility model is usually placed. It is only for the convenience of describing the present 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 should not be construed as a limitation to the present utility model.

[0019] Such as Figure 1As shown in the figure, an embodiment of the utility model includes a rotating assembly 1. The rotating assembly 1 forms a rotatable rotating surface. A forward clamping assembly 2 is fixedly connected to the rotating surface. The forward clamping assembly 2 forms a forward clamping double surface capable of relative movement. The forward clamping double surface is perpendicular to the rotating surface and can rotate with the rotation of the rotating surface. Secondly, a lateral clamping assembly 3 is also fixedly connected to the rotating surface. The lateral clamping assembly 3 forms a lateral clamping surface 34, and the lateral clamping surface 34 is always perpendicular to the forward clamping double surface.

[0020] Secondly, it also includes a hydraulic valve 4 for driving the relative movement of the forward clamping double surface and driving the movement of the lateral clamping surface 34. There are two working sequences of the hydraulic valve 4. One is that in this embodiment, when clamping goods for handling, the hydraulic valve 4 first controls the movement of the forward clamping assembly 2 to push the forward clamping double surfaces to move towards each other to clamp and fix the goods, and then it controls the lateral clamping assembly 3 to push the lateral clamping surface to approach the clamped goods along the lateral guide rail 32 to provide a lateral clamping force to the clamped goods; the other is that after the goods are transported to the designated position in this embodiment and the rotating fork is opened, the hydraulic valve 4 controls the forward clamping assembly 2 to push the forward clamping double surfaces to move away from each other to open the rotating fork. At the same time, it controls the lateral clamping assembly 3 to push the lateral clamping surface to move away from the goods along the lateral guide rail 32, so that the goods can be accurately placed at the designated position. Furthermore, this embodiment can clamp goods of different sizes, and the goods placed in the rotating fork can be subjected to at least three-directional pressures, so that the goods are not easily dropped or scattered, improving the working quality and working efficiency of the forklift.

[0021] Specifically, as shown in Figure 2 Figure a, the rotating assembly 1 includes a rotating base 11 and a rotating hinge 12. The rotating base 11 is installed on the forklift (conventional technology, not shown in the figure) through a plug-in type adapter or other connection methods that can be quickly connected and disassembled. The other side of the rotating base 11 is rotatably connected to the rotating hinge 12. The side of the rotating hinge 12 away from the rotating base 11 is the rotating surface, and the rotating surface can rotate 360 degrees around the rotation axis of the rotating hinge 12, enabling it to drive the forward clamping assembly 2 and the lateral clamping assembly 3 to rotate, and then drive the goods to rotate 360 degrees, and even lock the goods at a specific angle to meet the different handling requirements of different goods.

[0022] Secondly, as shown in Figure 2As shown in Fig. b, the forward clamping assembly 2 is fixedly connected to the rotary hinge 12 by bolt connection. It includes a first clamping member 22 and a second clamping member 23. The first and second clamping members 23 are parallel to each other, and their opposite surfaces form a first clamping surface and a second clamping surface. The first clamping surface and the second clamping surface are both perpendicular to the rotary surface, and they jointly form a forward clamping double surface. In this embodiment, the forklift forks 333 are used as the first and second clamping members 23. At the bottom of the first and second clamping members 23, a forward guide member 24 fixedly connected to the rotary hinge 12 and a forward cylinder 21 connecting seat are welded. The forward guide member 24 includes a guide rail welded to the bottom of the first and second clamping members 23 respectively and a slider 323 connected to the rotary hinge 12 by bolt connection.

[0023] In addition, the forward clamping assembly 2 further includes two forward cylinders 21. One end of each forward cylinder 21 is fixedly connected to the rotary hinge 12 by bolt connection, and the other end is respectively connected to the first and second clamping members 23 through the forward cylinder 21 connecting seat. The hydraulic valve 4 drives the relative movement of the first and second clamping surfaces by controlling the telescopic movement of the forward cylinders 21, that is, the first and second clamping members 23 approach each other when clamping the goods, and the first and second clamping members 23 move away from each other when releasing the goods.

[0024] In addition, as shown in Figure 3 Fig., the side clamping assembly 3 includes a side clamping member 33. The side clamping member 33 includes a panel 334. The side of the panel 334 close to the forward clamping assembly 2 is a side clamping surface 34. The side clamping surface 34 is perpendicular to the first and second clamping surfaces and the rotary surface. Then, a connecting plate 331 perpendicular to the side clamping surface 34 is fixedly connected to the bottom of the panel 334. The length direction of the connecting plate 331 is perpendicular to the first and second clamping surfaces. Four forklift forks 333 are perpendicularly welded to the side of the connecting plate 331 connecting the panel 334. The forklift forks 333 are evenly distributed along the length direction of the connecting plate 331, and the forklift forks 333 are also fixedly connected to the panel 334 at the same time. At the same time, reinforcing ribs 336 are welded at the joints of the forklift forks 333 and the connecting plate 331, which improves the structural strength of the side clamping member 33 and increases the upper limit of the lateral support force that the side clamping member 33 can exert on the goods. In addition, bent plates 335 are welded on both sides of the panel 334. The bent plates 335 are perpendicular to the connecting plate 331 and tangent to the side clamping surface 34, and their cross-sections are fan-shaped. The center of the fan is arranged on the side of the panel 334 away from the forward clamping assembly 2, so that the bent plates 335 can prevent the goods from being hooked and damaged during the process of handling the goods.

[0025] Secondly, the opposite surfaces of the connecting plate 331 are fixedly connected with a lateral cylinder connecting seat 332 and two groups of lateral guide members 32. The lateral guide member 32 includes a slider 323 fixedly connected to the rotating surface by bolts, a guide rail mounting plate 321 fixedly connected to the opposite surfaces of the connecting plate 331, and a T-shaped guide rail 322 welded to the surface of the guide rail mounting plate 321. A cavity with a T-shaped cross-section is formed inside the slider 323. The length direction of the guide rail mounting plate 321 is perpendicular to the lateral clamping surface 34 and parallel to the first and second clamping surfaces. The cross-section of the T-shaped guide rail 322 is T-shaped, and its small end face is welded to the guide rail mounting plate 321. The slider 323 and the T-shaped guide rail 322 can form a T-shaped moving pair, enabling it to fix the moving direction of the lateral clamping surface 34, and the T-shaped design can increase the upper limit of the bending moment borne by the lateral clamping member 33, enabling the lateral clamping member 33 to apply more lateral support force to the goods.

[0026] Secondly, the lateral clamping assembly 3 further includes a lateral cylinder 31 fixedly connected to the rotating surface by bolts. The lateral cylinder 31 is connected to the lateral clamping member 33 through the lateral cylinder connecting seat 332. The hydraulic valve 4 controls the telescopic movement of the lateral cylinder 31, so that the lateral clamping surface 34 can move closer to or away from the forward clamping assembly 2 along the lateral guide member 32.

[0027] This moving direction is parallel to the first and second clamping surfaces and the rotating surface, so that the lateral clamping surface 34 can always be perpendicular to the first and second clamping surfaces and the rotating surface during the movement, and further enabling the first and second clamping surfaces and the lateral clamping surface 34 to closely fit the surface of the goods during the process of handling the goods in this embodiment, reducing the dislocation of the stacked goods during the handling process and affecting the palletizing quality.

[0028] As Figure 1 shown, this embodiment includes a lateral clamping assembly 3, but a lateral clamping assembly 3 can be additionally installed on the opposite side, enabling this embodiment to provide clamping surfaces in more directions to clamp the goods and improving the stability and safety of the goods during the handling process.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
