Description

Technical Field

[0001] This utility model relates to the field of forklift auxiliary equipment technology, and in particular to an auxiliary device for forklifts. Background Technology

[0002] In the construction of marine engineering equipment, the installation of ring plates inside steel pipes is a common operation. Currently, forklifts are commonly used to transport the ring plates and necessary materials such as welding machines into the steel pipes. However, forklifts have limitations. Firstly, the shape and spacing of the forks are designed for standard pallets, which cannot guarantee stability and poses a risk of slippage when transporting materials on non-standard pallets. Secondly, the length of the forks is limited, making it unsuitable for pushing objects horizontally over long distances into narrow spaces. Therefore, this results in low efficiency for such specialized transportation operations, hindering both construction efficiency and safety.

[0003] To expand the operating range of forklifts, some auxiliary devices have been proposed in related technologies. These auxiliary devices extend the working distance of the forks to a certain extent by setting up telescopic mechanisms, but they cannot stably clamp ring-shaped objects, and therefore are not suitable for transporting ring-shaped objects. Utility Model Content

[0004] The main purpose of this invention is to provide an auxiliary device for forklifts, which aims to solve the problem that traditional forklift auxiliary devices are not suitable for transporting ring-shaped objects.

[0005] To achieve the above objectives, the forklift auxiliary device proposed in this utility model includes an extension arm, a fork fixing assembly, and a ring plate fixing assembly.

[0023] This utility model proposes an auxiliary device 100 for forklifts, which can be used, but is not limited to, for horizontally transporting objects such as ring plates 200 into a narrow steel pipe 300.

[0024] Please see Figures 1 to 3 In one embodiment of the present invention, the forklift auxiliary device 100 includes an extension arm 1, a fork fixing assembly 2, and a ring plate fixing assembly 3. The fork fixing assembly 2 includes two fork fixing members 21, which are respectively connected to both sides of the extension arm 1 and are symmetrically arranged about the axial direction of the extension arm 1. Each fork fixing member 21 has a slot 21a extending along the axial direction of the extension arm 1. The ring plate fixing assembly 3 is located at the end of the extension arm 1 away from the fork fixing assembly 2, and a ring plate fixing groove 3a is formed on the top wall of the ring plate fixing assembly 3.

[0025] In this embodiment, the forklift auxiliary device 100 is made of lightweight, high-strength metal material, such as steel. The forklift auxiliary device 100 includes an extension arm 1, a fork fixing assembly 2, and a ring plate fixing assembly 3, which are connected sequentially to form a continuous rigid structure. The extension arm 1 can be made of rectangular hollow steel, etc. The hollow cross-section reduces weight and forms a closed, anti-torsion box structure to prevent torsional deformation of the long arm under eccentric load. Ribs or other reinforcing members are provided inside or outside the extension arm 1. The wall thickness and length of the extension arm 1 are determined based on the inner diameter of the steel pipe 300 and the maximum forklift reach distance, ensuring that the deflection under rated load does not exceed the engineering allowable value. This embodiment does not impose any limitations on this aspect.

[0026] The fork fixing assembly 2 consists of two symmetrical fork fixing assemblies 2 on the left and right. The fork fixing assembly 2 is a fork sleeve. The fork sleeve can be formed by bending steel plates into a U-shaped or C-shaped structure, or by welding multiple steel plates into a U-shaped or C-shaped structure. A slot 21a is formed inside the fork sleeve. The width and height of the slot are slightly larger than the cross section of the forklift fork, so that the fork can be quickly inserted. When under load, the fork sleeve forms a surface contact with the fork through micro-elastic deformation, generating static friction force to prevent the device from lurching forward when stopping suddenly.

[0027] The ring plate fixing assembly 3 is located at the other end of the extension arm 1. For example, the ring fixing assembly can be connected to the end face or top surface of the end of the extension arm 1 away from the fork fixing assembly 2. The ring plate fixing assembly 3 can be formed by welding multiple block structures together to form a ring plate fixing groove 3a, or the ring plate fixing groove 3a can be machined into an integral structure by cutting. The groove opening of the ring plate fixing groove 3a is oriented upward to limit the inner wall and side wall of the ring plate 200, such as... Figure 4 As shown. The ring plate fixing assembly 3 can be fixedly connected to the extension arm 1 by welding, or it can be detachably connected to the extension arm 1 by bolts or other fasteners.

[0028] In this embodiment, the forklift auxiliary device 100 allows the forklift forks to be inserted into slot 21a to lift the forklift auxiliary device 100. By providing a ring plate fixing assembly 3 with a ring plate fixing groove 3a at one end of the extension arm 1 away from the fork fixing assembly 2, the ring plate 200 can be placed into the ring plate fixing groove 3a for fixing. Thus, by inserting the forklift into slot 21a and lifting the forklift auxiliary device 100 and the ring plate 200 fixed in the fixing groove, the ring plate 200 can be transported.

[0029] Further, please refer to Figure 3 In one embodiment of this utility model, the ring plate fixing groove 3a is gradually expanded along the direction opposite to the extending arm 1.

[0030] In this embodiment, the opening of the ring plate fixing groove 3a is set upward, and the ring plate fixing groove 3a gradually expands outward in the direction away from the extension arm 1 to form a trumpet-shaped profile. This expansion angle is set according to the commonly used thickness difference range of the ring plate 200, so that the width of the groove increases uniformly along the depth direction, thereby automatically correcting its center position during the falling process of the ring plate 200 and reducing the difficulty of manual hole alignment; at the same time, the same groove can accommodate a batch of ring plates 200 with certain differences in outer diameter, improving the applicability of the ring plate fixing assembly 3 and reducing the frequency of replacing the ring plate fixing assembly 3.

[0031] Further, please refer to Figure 1 and Figure 2 In one embodiment of this utility model, the bottom wall of the ring plate fixing groove 3a is set with an arc surface.

[0032] In this embodiment, based on the above embodiments, the bottom wall of the ring plate fixing groove 3a can be further improved so that the bottom wall of the ring plate fixing groove 3a is an upwardly convex arc surface. The curvature of the arc surface is close to the curvature of the inner circle of a common ring plate 200. This allows the inner ring surface of the ring plate 200 to contact the arc surface after it is placed, reducing the pressure per unit area and preventing local indentations or damage to the ring plate 200. The arc surface also plays a self-centering role, automatically aligning the top of the inner ring with the top of the arc surface under the weight of the ring plate 200. Furthermore, the edge of the arc surface can be smoothly transitioned to the side wall of the groove, eliminating sharp edges and preventing the ring plate 200 from being scratched during transportation.

[0033] Further, please refer to Figures 1 to 3 In one embodiment of this utility model, the ring plate fixing assembly 3 includes a support column 31, a receiving column 32, and two limiting members 33; the support column 31 is connected to the top wall of the extension arm 1 and is perpendicular to the axial direction of the extension arm 1; the receiving column 32 is connected to the end of the support column 31 away from the extension arm 1 and is arranged parallel to the axial direction of the extension arm 1; the two limiting members 33 are respectively connected to the two ends of the receiving column 32, and the two limiting members 33 and the receiving column 32 enclose to form a ring plate fixing groove 3a.

[0034] In this embodiment, the ring plate fixing assembly 3 includes a support column 31, a receiving column 32, and two limiting members 33. The support column 31, receiving column 32, and two limiting members 33 can be welded and fixed using a separate welding process to form an integrated rigid structure. The support column 31 and receiving column 32 are cylindrical. The support column 31 is perpendicular to the axis of the extension arm 1 and is welded to its top wall or connected by fasteners. The receiving column 32 is horizontally welded to the top of the support column 31. The two limiting members 33 are welded to both ends of the receiving column 32. The two limiting members 33 are the same size and shape, both trapezoidal. The two limiting members 33 and the receiving column 32 form a ring plate fixing groove 3a, meaning that the inclined surfaces of the two trapezoidal limiting members are connected to the side wall of the receiving column 32, and the lowest point of the inclined surface is lower than or equal to the apex of the arc surface of the side wall of the receiving column 32. Figure 3 The lowest point of the inclined plane shown is higher than the apex of the arc surface of the side wall of the receiving column 32, so as to ensure that the arc-shaped bottom wall of the ring plate fixing groove 3a can contact the inner ring of the ring plate 200, and ensure that the receiving column 32 and the support column 31 can provide stable support for the ring plate 200. The two limiting members 33 can also be further extended to connect with the extension arm 1, such as by welding or by fasteners, to improve the connection strength between the ring plate fixing assembly 3 and the extension arm 1. Disassembling the ring plate fixing assembly 3 as a whole into the support column 31, the receiving column 32 and the two limiting members 33 can reduce the difficulty of manufacturing process, avoid the material waste and machine time consumption caused by milling the groove of a whole thick plate, significantly simplify the manufacturing process and reduce manufacturing costs.

[0035] Further, please refer to Figure 1 and Figure 2In one embodiment of the present invention, the extension arm 1 includes a top plate 11, a bottom plate 12 and a web plate 13. The top plate 11 and the bottom plate 12 are arranged in parallel, and the web plate 13 is vertically connected to the top plate 11 and the bottom plate 12.

[0036] In this embodiment, the extension arm 1 is welded together from a top plate 11, a bottom plate 12, and a web plate 13, and the cross-section of the extension arm 1 is I-shaped. The top plate 11 is parallel to the bottom plate 12, and the web plate 13 is perpendicularly connected to the top plate 11 and the bottom plate 12. The I-shaped cross-section can obtain a higher bending moment of inertia with the same amount of steel, so that the extension arm 1 maintains sufficient stiffness even when overhanging a long distance under full load; at the same time, the open cross-section facilitates the internal welding of reinforcing ribs.

[0037] Further, please refer to Figures 1 to 3 In one embodiment of the present invention, an end cap 14 is provided at the end of the extension arm 1 away from the fork fixing assembly 2. The end cap 14 is arranged perpendicular to the axial direction of the extension arm 1 and connects the top plate 11, the web plate 13 and the bottom plate 12.

[0038] In this embodiment, an end cap 14 is added to the cantilever end of the extension arm 1 away from the fork fixing assembly 2. The extension arm 1 has an I-shaped cross-section, and the end cap 14 is rectangular to adapt to the cross-section of the extension arm 1. The end cap 14 intersects perpendicularly with the top plate 11, bottom plate 12, and web plate 13, and is continuously welded along the entire cross-section to form a closed diaphragm. This diaphragm can prevent the I-shaped cross-section from being distorted at the end due to local warping, and at the same time, it disperses the concentrated force from the ring plate fixing assembly 3 to the top plate 11, bottom plate 12, and web plate 13, avoiding tearing initiation points at the weld intersection.

[0039] Further, please refer to Figures 1 to 3 In one embodiment of the present invention, the forklift auxiliary device 100 further includes at least two suspension supports 4, which are symmetrically arranged about the web plate 13 and connected to the top wall of the bottom plate 12; the suspension supports 4, the bottom plate 12 and the web plate 13 enclose a suspension groove 4a, and an avoidance notch 4b communicating with the suspension groove 4a is formed between the suspension supports 4 and the top plate 11.

[0040] In this embodiment, a pair of suspension supports 4 are added to the top wall of the base plate 12 of the extension arm 1. The two suspension supports 4 are symmetrically arranged about the web plate 13 and fixedly connected to the base plate 12. The suspension supports 4 are used to suspend the cable sling 400 to transport loose objects into the steel pipe 300. The suspension supports 4 can be cylindrical structures perpendicular to the base plate 12, or other columnar structures. The suspension supports 4, the base plate 12, and the web plate 13 form a suspension groove 4a. The suspension groove 4a is used to place and suspend ropes or slings on the suspension supports 4. A certain distance is spaced between the top wall of the support and the top plate 11 to form a clearance notch 4b. The clearance notch allows the sling to slide laterally into the suspension groove 4a. Two suspension supports 4 form a group. The two suspension supports 4 in the same group are symmetrically arranged about the web plate 13. Multiple groups of suspension supports 4 can be arranged at intervals along the axial direction of the extension arm 1 to increase the transport capacity and facilitate the adjustment of the suspension position of the cable sling 400.

[0041] Further, please refer to Figures 1 to 3 In one embodiment of the present invention, the fork fixing member 21 is arranged perpendicular to the axial direction of the extension arm 1. The fork fixing assembly 2 also includes a first reinforcing member 22. The first reinforcing member 22 connects the side wall of the fork fixing member 21 and the side wall of the extension arm 1, and gradually contracts along the end of the fork fixing member 21 near the extension arm 1 to the end of the fork fixing member 21 away from the extension arm 1.

[0042] In this embodiment, a first reinforcing member 22 is added between the fork fixing member 21 and the extension arm 1 to enhance the connection strength between them. The reinforcing member can be a plate that gradually tapers from one end of the fork fixing member 21 near the extension arm 1 to the other end, such as a right-angled triangle. One right-angled side of the triangle is fully welded to the side wall of the fork fixing member 21, and the other right-angled side is fully welded to the side wall of the extension arm 1. The hypotenuse gradually tapers from the root of the fork fixing member 21 towards the cantilever end, forming a gradual transition. This gradual shape provides the largest cross-section in the area of ​​maximum shear force, gradually decreasing towards the cantilever end of the fork fixing member 21, thus reducing material usage while ensuring the required connection strength.

[0043] Further, please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the fork fixing member 21 is arranged perpendicular to the axial direction of the extension arm 1, and the fork fixing assembly 2 further includes a second reinforcing member 23, which connects the end of the fork fixing member 21 away from the extension arm 1 to the bottom wall of the extension arm 1.

[0044] In this embodiment, a second reinforcing member 23 is added between the fork fixing member 21 and the extension arm 1. One end of the second reinforcing member 23 is welded to the bottom surface of the end of the fork fixing member 21 away from the extension arm 1, and the other end extends towards the side wall of the extension arm 1 and connects to the bottom wall of the extension arm 1. The three form a stable triangular region in space. The second reinforcing member 23 can distribute the weight of the goods and prevent the connection between the fork fixing member 21 and the extension arm 1 from cracking due to stress concentration.

[0045] Further, please refer to Figures 1 to 3 In one embodiment of the present invention, the forklift auxiliary device 100 includes at least two fork fixing components 2, which are distributed at intervals along the axial direction of the extension arm 1.

[0046] In this embodiment, two sets of fork fixing assemblies 2 are arranged on the same side of the extension arm 1, with the two sets spaced back and forth along the axis of the arm, the spacing matching the length of the two forks of the forklift. It should be noted that by setting two sets of spaced-apart fork fixing assemblies 2, the extension arm 1 acts as a lever, with the set of fork fixing assemblies 2 closer to the ring plate fixing assembly 3 serving as a fulcrum, and the set of fork fixing assemblies 2 further away from the ring plate fixing assembly 3 providing a downward reaction force. When the ring plate fixing assembly 3 is subjected to the gravity of the ring plate 200, it can prevent the extension arm 1 from rotating, thus maintaining the stability of the forklift auxiliary device 100 under load. Furthermore, the material consumption of the fork fixing assemblies 2 in this embodiment is less. When using only one set of fork fixing assemblies 2, in order to maintain the stability of the forklift auxiliary device 100 under load, the fork fixing assembly 2 needs to extend a sufficient distance along the axial direction of the extension arm 1. This embodiment uses at least two fork fixing assemblies 2, which reduces the volume of each fork fixing assembly 2, thereby reducing the overall material consumption.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
