Description

Technical Field

[0001] This utility model relates to the technical field of forklift equipment inspection, specifically to a hose guide wheel assembly and a forklift device. Background Technology

[0002] Forklift hoses are an important component of the hydraulic system of forklift equipment. They are used to transmit hydraulic oil, providing power for the lifting and lowering of the forklift mast. Forklift hoses are typically mounted on hose guide wheels on the mast. Through the guiding and fixing function of the hose guide wheels, the forklift hoses can be raised and lowered synchronously with the mast.

[0003] However, forklift hoses are prone to length changes due to usage time and environment. If the hose is not replaced in time after the length changes, the connection between the hose and the hose guide wheel assembly may become loose or even detach, affecting the stability and security of the hose installation. Frequent replacement of the hose significantly increases the cost of using it. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a hose guide wheel assembly is provided, the technical solution of which is as follows.

[0005] The hose guide wheel assembly includes a first support member, a wheel body, and a positioning assembly. A first groove is formed vertically on the side wall of the first support member. The wheel body is disposed within the first support member, and its central axis passes horizontally through the first groove. The positioning assembly includes a first positioning member and a second positioning member. The first positioning member passes vertically through the first groove and is movably connected to the central axis, while the second positioning member is movably connected horizontally to the central axis. The first and second positioning members cooperate to define the relative position of the central axis and the first groove.

[0006] The present invention relates to a hose guide wheel assembly. A first groove can be provided on the side wall of the first support member in the vertical direction. When the wheel is set in the first support member, the central axis of the wheel can pass through the first groove and can move up and down in the vertical direction within the first groove. This allows the first positioning member and the second positioning member to work together on the central axis of the wheel, thereby limiting the relative position of the central axis and the first groove (i.e., fixing the central axis of the wheel in a position within the first groove). Thus, by adjusting the height of the wheel in the vertical direction, the hose guide wheel assembly can be adapted to hoses of different lengths, making it suitable for different usage scenarios and needs, effectively improving the practicality and flexibility of the hose guide wheel assembly.

[0007] For example, the hose guide wheel assembly also includes a second support member, which is covered by the first support member. A second groove is formed on the side wall of the second support member in the vertical direction, and the central shaft passes through the first groove and abuts against the bottom of the second groove.

[0008] For example, the second positioning element is movably disposed at the end of the central shaft to apply a force against the first groove to the second groove.

[0009] For example, a step portion is provided on the end of the first positioning member away from the first groove, the step portion being used to abut against the first support member to limit the downward displacement of the central axis in the vertical direction.

[0010] For example, the first support member includes a first part and a second part disposed opposite to each other, with a first groove formed on the first part and the second part respectively, a wheel located between the first part and the second part, and two first positioning members, each passing through the corresponding first groove and movably connected to both ends of the central shaft.

[0011] For example, the second support member includes a third part and a fourth part disposed opposite to each other, the third part being disposed corresponding to the first part and the fourth part being disposed corresponding to the second part, and a second groove being formed on the third part and the fourth part respectively.

[0012] For example, a first through groove is formed on the first part and the second part respectively, and the end of the first through groove away from the first groove is inclined toward the step portion.

[0013] For example, the third and fourth portions are respectively formed with second through grooves that penetrate the second groove body, and the end of the second through groove away from the second groove body is inclined toward the step portion.

[0014] For example, the length of the first groove ranges from 40 mm to 60 mm.

[0015] According to another aspect of the present invention, a forklift device is also provided, including the hose guide wheel assembly as described above.

[0016] The advantages and features of this utility model will be described in detail below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0025] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0026] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0027] Existing forklift hose guide wheel assemblies guide and fix the hose when it is wound around the guide wheel assembly, allowing the hose to move synchronously with the forklift mast during vertical movement. However, the hose length may change due to environmental factors (such as high temperatures) and usage time, making it incompatible with the hose guide wheel assembly.

[0028] Based on this, one embodiment of the present invention provides a hose guide wheel assembly, which can be adapted to hoses of different lengths, and thus can be used in different application scenarios and to meet different needs. The following will describe in detail a hose guide wheel assembly according to an embodiment of the present invention with reference to the accompanying drawings.

[0029] like Figures 1 to 5 As shown, the hose guide wheel assembly includes a first support member 1, a wheel body 2, and a positioning assembly 3. A first groove 11 is formed vertically on the side wall of the first support member 1. The wheel body 2 is disposed within the first support member 1, and its central shaft 21 passes horizontally through the first groove 11. The positioning assembly 3 includes a first positioning member 31 and a second positioning member 32. The first positioning member 31 passes vertically through the first groove 11 and is movably connected to the central shaft 21, while the second positioning member 32 is movably connected horizontally to the central shaft 21. The first positioning member 31 and the second positioning member 32 cooperate to define the relative position of the central shaft 21 and the first groove 11.

[0030] The first support member 1 can be U-shaped, and the first groove 11 can be formed vertically on the vertical portion of the U-shaped first support member 1. An accommodating space can be formed within the U-shaped first support member 1, and the wheel 2 can be disposed within this accommodating space. When the wheel 2 is disposed within the accommodating space of the first support member 1, the central shaft 21 of the wheel 2 can protrude through the first groove 11 and be exposed outside the first support member 1.

[0031] The first positioning member 31 and the second positioning member 32 can be movably connected to the central shaft 21 of the wheel body 2, respectively, to flexibly adjust the height position of the central shaft 21 within the first groove 11. Specifically, the first positioning member 31 can pass through the first groove 11 vertically and be movably connected to the central shaft 21, thereby applying a pulling force to the central shaft 21. It is understood that the height position of the wheel body 2 in the vertical direction can be adjusted by adjusting the position of the central shaft 21 on the first positioning member 31. The second positioning member 32 can be movably connected to the central shaft 21 horizontally, thereby applying a resisting force to the central shaft 21 to confine the adjusted central shaft 21 within the first groove 11.

[0032] It is understandable that the first positioning member 31 and the second positioning member 32 can be snapped or threaded to the central shaft 21 of the wheel body 2, respectively. Threaded connection is preferred, so as to simplify the connection method while ensuring connection strength.

[0033] The hose guide wheel assembly of this utility model has a first groove 11 vertically provided on the side wall of the first support member 1. When the wheel 2 is placed inside the first support member 1, the central shaft 21 of the wheel 2 can pass through the first groove 11 and can move up and down vertically within the first groove 11. This allows the first positioning member 31 and the second positioning member 32 to work together on the central shaft 21 of the wheel 2, thereby limiting the relative position of the central shaft 21 and the first groove 11 (i.e., fixing the central shaft 21 of the wheel 2 at a certain height in the first groove 11). Thus, by adjusting the height of the wheel 2 in the vertical direction, the hose guide wheel assembly can be adapted to hoses of different lengths, making it suitable for different usage scenarios and needs, effectively improving the practicality and flexibility of the hose guide wheel assembly.

[0034] In some embodiments, such as Figures 1 to 5 As shown, the hose guide wheel assembly also includes a second support member 4, which is covered by the first support member 1. A second groove 41 is formed on the side wall of the second support member 4 in the vertical direction. The central shaft 21 passes through the first groove 11 and abuts against the bottom of the second groove 41.

[0035] The shape of the second support member 4 can be an inverted U-shape. When the inverted U-shaped second support member 4 is placed over the U-shaped first support member 1, the aforementioned accommodating space can be formed between the first support member 1 and the second support member 4.

[0036] The vertical portion of the U-shaped second support member 4 can have a second groove 41 formed in the vertical direction, and the central shaft 21 can pass through the first groove 11 and the second groove 41 in sequence and be exposed outside the second support member 4.

[0037] In the above embodiment, when the second support member 4 is covered outside the first support member 1, the central shaft 21 passes through the first groove 11 and abuts against the bottom of the second groove 41. In this way, the second support member 4 can apply a lifting force to the central shaft 21 through the bottom of the second groove 41, which not only ensures that the central shaft 21 is limited to the height position of the first groove 11, but also reduces the weight of the wheel 2 borne by the first positioning member 31, improves the service life of the first positioning member 31, and effectively improves the reliability of the hose guide wheel assembly.

[0038] In some embodiments, such as Figures 1 to 5 As shown, the second positioning member 32 is movably disposed at the end of the central shaft 21 to apply a force against the first groove 11 to the second groove 41.

[0039] Specifically, the second positioning element 32 can be a nut, and the outer wall of the central shaft 21 can be formed with a thread that matches the nut.

[0040] In the above embodiment, the second positioning member 32 can apply a force against the first groove 11 to the second groove 41, thereby ensuring that the first groove 11 and the second groove 41 fit tightly together, thus ensuring the strength of the force applied by the second positioning member 32 to the central shaft 21 in the horizontal direction, and effectively improving the firmness and stability of the hose guide wheel assembly.

[0041] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, a step portion 311 is provided on the end of the first positioning member 31 away from the first groove 11. The step portion 311 is used to abut against the first support member 1 to limit the downward displacement of the central shaft 21 in the vertical direction.

[0042] The first positioning member 31 can be rod-shaped, and a stepped portion 311 can be provided at one end of the rod-shaped first positioning member 31. The first positioning member 31 and the stepped portion 311 can be detachably connected or integrally formed. The detachable connection can include plug-in connection or threaded connection, etc., and this application does not specifically limit it. Preferably, it is integrally formed to ensure the connection strength between the first positioning member 31 and the stepped portion 311. Specifically, the first positioning member 31 can be a screw, which can be vertically inserted into the central shaft 21 and threadedly connected to the central shaft 21.

[0043] The stepped portion 311 has an abutting surface on the side facing the first groove 11. When the first positioning member 31 is inserted into the first support member 1, the abutting surface of the stepped portion 311 can abut against the upper wall surface 15 of the first support member 1.

[0044] In the above embodiment, the step portion 311 can be used to abut against the first support member 1 to limit the downward displacement of the central shaft 21 in the vertical direction. In this way, on the one hand, the cooperation between the step portion 311 and the first support member 1 can form a pulling force applied to the central shaft 21. On the other hand, the step portion 311 can also prevent the first positioning member 31 from disengaging from the first support member 1 when force is applied, further improving the reliability and safety of the hose guide wheel assembly.

[0045] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the first support member 1 includes a first part 12 and a second part 13 arranged opposite to each other. The first part 12 and the second part 13 are respectively formed with first grooves 11. The wheel body 2 is located between the first part 12 and the second part 13. There are two first positioning members 31. The two first positioning members 31 pass through the first grooves 11 corresponding to them and are movably connected to the two ends of the central shaft 21.

[0046] The first part 12 and the second part 13 mentioned above can be the vertical parts of the U-shaped first support member 1. The shape of the first part 12 and the second part 13 can both be plate-shaped. The plate-shaped first part 12 and the second part 13 can be located on both sides of the wheel body 2, so that the two ends of the central shaft 21 of the wheel body 2 can be respectively inserted into the corresponding first groove 11.

[0047] In the above embodiment, the two ends of the central shaft 21 of the wheel body 2 can be respectively inserted into the first groove 11 formed on the first part 12 and the second part 13. In this way, the two ends of the central shaft 21 can be subjected to the tension from the first positioning member 31, thereby ensuring that the wheel body 2 is subjected to uniform force. At the same time, the structure of the first support member 1 is simplified, and the reliability and stability of the hose guide wheel assembly are effectively improved.

[0048] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the second support member 4 includes a third part 42 and a fourth part 43 arranged opposite to each other. The third part 42 is arranged corresponding to the first part 12, and the fourth part 43 is arranged corresponding to the second part 13. A second groove 41 is formed on the third part 42 and the fourth part 43 respectively.

[0049] The aforementioned third part 42 and fourth part 43 can be the vertical portions of the inverted U-shaped second support member 4. Both the third part 42 and the fourth part 43 can be plate-shaped. The plate-shaped third part 42 can be correspondingly disposed on the outside of the first part 12. One end of the wheel 2 can be sequentially inserted into the first groove 11 on the first part 12 and the second groove 41 on the third part 42. The plate-shaped fourth part 43 can be correspondingly disposed on the outside of the second part 13. The other end of the wheel 2 can be sequentially inserted into the first groove 11 on the second part 13 and the second groove 41 on the fourth part 43.

[0050] In the above embodiment, the two ends of the central shaft 21 of the wheel body 2 can be subjected to lifting forces from the third part 42 and the fourth part 43 respectively. This not only ensures that the wheel body 2 is subjected to uniform force, but also simplifies the structure of the second support member 4, and further improves the reliability and stability of the hose guide wheel assembly.

[0051] In some embodiments, such as Figure 4 and Figure 5 As shown, the first part 12 and the second part 13 are respectively formed with a first through groove 14 that passes through the first groove 11. The end of the first through groove 14 away from the first groove 11 is inclined toward the step part 311.

[0052] The first through groove 14 can be arranged horizontally and connected to the end of the first groove 11 near the second support member 4.

[0053] In the above embodiment, the first through groove 14 can connect the first groove 11 to the outside, so that the end of the central shaft 21 of the wheel body 2 can enter the first groove 11 through the first through groove 14. When the hose is wound around the wheel body 2, the hose will apply a downward force to the wheel body 2. The end of the first through groove 14 away from the first groove 11 can be inclined towards the step portion 311. In this way, when the first positioning member 31 and the second positioning member 32 are separated from the central shaft 21 due to failure or accident, the situation of the central shaft 21 being separated from the first groove 11 through the first through groove 14 under the force applied by the hose is avoided, which significantly improves the reliability and safety of the hose guide wheel assembly.

[0054] In some embodiments, such as Figure 4 and Figure 5 As shown, the third part 42 and the fourth part 43 are respectively formed with a second through groove 44 that passes through the second groove 41. The end of the second through groove 44 away from the second groove 41 is inclined toward the step part 311.

[0055] The aforementioned second through groove 44 can be arranged horizontally and connected to the end of the second groove 41 near the first support member 1.

[0056] In the above embodiment, the second through groove 44 can connect the second groove 41 to the outside, so that the end of the central shaft 21 of the wheel body 2 can enter the second groove 41 through the second through groove 44. When the hose is wound around the wheel body 2, the hose will apply a downward force to the wheel body 2. The end of the second through groove 44 away from the second groove 41 can be inclined towards the step portion 311. In this way, when the first positioning member 31 and the second positioning member 32 are separated from the central shaft 21 due to failure or accident, the situation of the central shaft 21 being separated from the second groove 41 through the second through groove 44 under the force applied by the hose will be avoided, further improving the reliability and safety of the hose guide wheel assembly.

[0057] In some embodiments, the length of the first groove 11 ranges from 40 mm to 60 mm.

[0058] The length of the first groove 11 is in the range of 40 mm to 60 mm, for example, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, etc., preferably 50 mm.

[0059] In the above embodiments, the length of the first groove 11 can be in the range of 40 mm to 60 mm. By adjusting the position of the wheel 2 in the first groove 11, the hose guide wheel assembly can be adapted to hoses of different lengths, which significantly improves the practicality and applicability of the hose guide wheel assembly.
