Description

Technical Field

[0001] The utility model relates to the field of steel production, in particular to a forklift double-tire connecting piece and a double-tire structure. Background Art

[0002] Forklifts are widely used in material handling and loading and unloading, and the performance of their tires is crucial to the performance of forklifts. At present, most forklift tires on the market are single-tire designs, and due to the limitations of the single-tire structure, the tires cannot adapt to different operating environments at the same time. For example, when quick steering is required (without affecting the minimum turning radius), the risk of rollover stability is high, affecting the normal operation of the forklift. Although dual-tire forklifts have appeared, the existing single-tire forklifts are large and have not yet reached the scrap age. Replacing all of them with dual-tire forklifts is costly and causes waste of existing forklifts. Utility Model Content

[0003] The utility model aims to provide a forklift double-tire connecting piece and a double-tire structure, so as to upgrade and transform the existing single-tire forklift and improve the steering stability.

[0004] A forklift double-tire connector comprises: an outer flange, a connecting tube, and an inner flange arranged in sequence, the connecting tube connecting the inner flange and the outer flange, the inner flange being provided with a plurality of inner mounting holes surrounding the outer circumference of the inner through hole, the outer flange being provided with a plurality of outer mounting holes surrounding the outer circumference of the outer through hole, a nut slot corresponding to the outer mounting hole being provided on the side of the outer flange facing the inner flange, and the nut slot being communicated with the outer mounting hole.

[0005] In one embodiment, the connecting tube connects the inner flange and the inner edge of the outer flange.

[0006] In one embodiment, the connecting tube connects the inner flange and the outer edge of the outer flange.

[0007] In one of the embodiments, the outer flange is provided with an outer through hole, and the connecting tube is communicated with the outer through hole.

[0008] In one embodiment, the inner flange is provided with an inner through hole, and the connecting tube is communicated with the inner through hole.

[0009] A forklift double-tire structure comprises: an inner wheel, an outer wheel, and a forklift double-tire connecting piece as described in any one of the above items, wherein the connecting piece is located between the inner wheel and the outer wheel, the screw of the axle passes through a through hole on the wheel hub of the inner wheel, passes through the inner mounting hole, and is tightened with an inner nut, a bolt is provided in the outer mounting hole, the nut of the bolt is located in the nut slot, and the bolt passes through the through hole on the wheel hub of the outer wheel and is tightened with an outer nut.

[0010] Compared with the prior art, the advantages of the tire device of the forklift double-tire outer rim of the utility model that is adapted to work in different environments are:

[0011] The utility model can add a second wheel to the original single wheel of the forklift through the design of the connecting piece, increase the fulcrum of the forklift turning, avoid rollover, and improve safety. In addition, the utility model sets a nut clamping groove on the outer flange, and the nut clamping groove is used to clamp the head of the screw or the nut. Because the distance between the outer wheel and the inner wheel is small, especially when installing the outer wheel, the diameter of the outer wheel is larger than the connecting piece, which blocks the line of sight and has almost no operating space, making it inconvenient to tighten the nut and nut. The outer flange of the utility model has a nut clamping groove that can limit the nut head of the screw or limit the rotation of the nut, making it convenient to tighten the screw and nut, thereby realizing the installation of the outer wheel.

[0024] like Figures 1 to 6 As shown, the forklift double tire connector 30 includes: an outer flange 32, a connecting tube 33, and an inner flange 31 arranged in sequence, the connecting tube 33 connects the inner flange 31 and the outer flange 32, the inner flange 31 is provided with a plurality of inner mounting holes 34 surrounding the outer periphery of the inner through hole 37, the outer flange 32 is provided with a plurality of outer mounting holes 35 surrounding the outer periphery of the outer through hole 38, and the outer flange 32 is provided with a nut slot 36 corresponding to the outer mounting hole 35 on the side facing the inner flange 31, and the nut slot 36 is connected to the outer mounting hole 35. The inner flange 31 is used to connect the inner wheel 13 (i.e., the existing single wheel of the forklift), and the outer flange 32 is used to connect the outer wheel 20 (i.e., the outer wheel 20 is installed outside the existing single wheel).

[0025] Through the design of the connector 30 of the utility model, a second wheel can be installed outside the original single wheel of the forklift, increasing the fulcrum for the forklift to turn, avoiding rollover, and improving safety. In addition, the utility model sets a nut slot 36 on the outer flange 32, and the nut slot 36 is used to clamp the head of the screw or the nut. Because the distance between the outer wheel 20 and the inner wheel 13 is small, especially when installing the outer wheel 20, the diameter of the outer wheel 20 is larger than the connector 30, blocking the line of sight, almost no operating space, and inconvenient to tighten the nuts and bolts, the outer flange 32 of the utility model has a nut slot 36 that can limit the head of the bolt 21, or limit the rotation of the outer nut 22, which is convenient for tightening the nut of the screw 11, thereby realizing the installation of the outer wheel 20.

[0026] In this embodiment, Figure 1-5 As shown, the connecting tube 33 connects the outer edges of the inner flange 31 and the outer flange 32. The outer flange 32 is provided with an outer through hole 38, and the connecting tube 33 is communicated with the outer through hole 38. The outer through hole 38 provides an operating space for installing the connecting member 30 and the inner wheel 13 to the screw 11 of the axle 10. The hand-held tool extends into the connecting tube 33 from the outer through hole 38, and the inner nut 12 is tightened to achieve the installation of the inner wheel 13. In addition, the outer through hole 38 provides an operating space for the installation of the outer wheel 20. After the inner wheel 13 is installed, the bolt 21 is inserted from the inside to the outside through the nut slot 36 and the outer mounting hole 35, and the head of the bolt 21 is clamped by the nut slot 36 and the outer nut 22 is tightened, thereby achieving the installation of the outer wheel 20. The inner flange 31 is provided with an inner through hole 37, and the connecting tube 33 is communicated with the inner through hole 37. The inner through hole 37 is used to provide an installation space for the axle 10 when the axle 10 of some vehicles is longer.

[0027] However, it is not limited to this embodiment. Figure 6 As shown, the connecting tube 33 connects the inner edge of the inner flange 31 and the outer flange 32. In this case, the inner wheel 13 is installed outside the connecting tube 33. After the inner wheel 13 is installed, the head of the bolt 21 is clamped by the nut clamping groove 36 and the outer nut 22 is tightened, so as to realize the installation of the outer wheel 20.

[0028] like Figure 5As shown, the forklift double tire structure of this embodiment includes: an inner wheel 13, an outer wheel 20, and a forklift double tire connector 30. The connector 30 is located between the inner wheel 13 and the outer wheel 20. The screw 11 of the axle 10 passes through the through hole on the wheel hub 14 of the inner wheel 13, passes through the inner mounting hole 34, and is tightened with the inner nut 12. A bolt 21 is provided in the outer mounting hole 35. The nut of the bolt 21 is located in the nut slot 36. The bolt 21 passes through the through hole on the wheel hub 23 of the outer wheel 20 and is tightened with the outer nut 22. In this way, the outer wheel 20 is installed on the existing forklift. The outer wheel 20 serves as an auxiliary wheel to assist when the forklift turns to prevent the forklift from tipping over. However, it is not limited to this embodiment. Since the utility model provides a forklift double tire connector 30, different outer wheels 20 can be installed on the existing single tire forklift as needed to achieve different functions. For example, on a smooth ground, an outer wheel 20 with a large friction coefficient can be installed to avoid slipping.

[0029] In this embodiment, the outer nut 22 is located outside the outer flange 32. However, it is not limited to this embodiment, and the outer nut 22 can also be placed in the nut slot 36, and the bolt 21 passes through the outer mounting hole 35 from the outside of the outer flange 32 to the inside and is tightened with the outer nut 22.

[0030] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
