[0017] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0018] It should be clear that the described embodiments are merely a part of rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without any creative efforts shall fall within the scope of protection of the present disclosure.

[0019] Embodiments of the present disclosure provide a forklift, which can improve the ease of replacement of supporting legs and improve an overall assembly accuracy of the forklift.

[0020] The embodiments of the present disclosure will be further described below with reference to FIG. 1 to FIG. 6.

[0021] FIG. 1 illustrates an exploded perspective view of a forklift according to an embodiment of the present disclosure. Referring to FIG. 1, the forklift according to the present embodiment includes a frame 1, a first supporting leg 2, and a mast 3.

[0022] The first supporting leg 2 is detachably mounted on the frame 1, and the mast 3 is detachably mounted on the first supporting leg 2, so that the first supporting leg 2 can be easily replaced.

[0023] Specifically, the frame 1 may be provided with a first connecting portion (not shown in the drawings), and the first supporting leg 2 is detachably mounted on the first connecting portion of the frame 1. The mast 3 may be provided with a second connecting portion 31, the mast 3 is detachably mounted on the first supporting leg 2 through the second connecting portion 31, and a connecting position between the mast 3 and the first supporting leg 2 is close to the frame 1. That is, the first connecting portion of the frame 1 and the second connecting portion 31 of the mast 3 are detachably connected to different positions on a same side of the first supporting leg 2.

[0024] Referring to FIG. 2, casters 21 are mounted at a bottom of the first supporting leg 2, so that the first supporting leg 2 can provide good support for the mast 3 mounted on the first supporting leg 2, and can cooperate with the frame 1 to realize movement of the forklift. In an example, the casters 21 may be disposed at a bottom of the first supporting leg 2, on a side of the first supporting leg 2 away from the frame 1.

[0025] The second connecting portion 31 of the mast 3 is disposed on a side of the mast 3 close to the frame 1, and a fork 32 is transversely disposed on a side of the mast 3 away from the frame 1, which is convenient for the forklift to handle goods.

[0026] The forklift provided by the embodiment of the present disclosure includes the frame 1, the first supporting leg 2, and the mast 3. The first supporting leg 2 is detachably mounted on the frame 1, and the mast 3 is detachably mounted on the first supporting leg 2, so that the first supporting leg 2 can be easily replaced, enabling an increased interchangeability of supporting legs.

[0027] Referring to FIG. 1, in an embodiment, the second connecting portion 31 on the mast 3 includes a second upper connecting portion 311 and a second lower connecting portion 312, which are vertically disposed and spaced apart from each other, and the second upper connecting portion 311 is located above the second lower connecting portion 312. The first supporting leg 2 is detachably connected to the second upper connecting portion 311 on the mast 3 in a first position 22, and the first supporting leg 2 is detachably connected to the second lower connecting portion 312 on the mast 3 in a second position 23.

[0028] Exemplarily, the first supporting leg 2 may include a traveling supporting leg 91 and a bracket 92 vertically fixedly connected to the traveling supporting leg. The bracket 92 is connected to the traveling supporting leg at an end of the traveling supporting leg close to the frame 1. The traveling supporting leg is connected to the mast 3 on a first end thereof, and the caster 21 are mounted at a bottom of the traveling supporting leg on a second end of the traveling supporting leg.

[0029] The first position 22 and the second position 23 of the first supporting leg 2 may be vertically disposed on the bracket 92 and be spaced apart from each other. The first position 22 on the bracket 92 is disposed corresponding to the second upper connecting portion 311 of the mast 3, and the second position 23 on the bracket 92 is disposed corresponding to the second lower connecting portion 312 of the mast 3.

[0030] A connection structure between the mast 3 and the first supporting leg 2 affects a height of center of gravity of an assembled structure formed by connecting the mast 3 and the first supporting leg 2. Compared with a case in which the mast 3 is connected to the first supporting leg 2 by solely connecting the second lower connecting portion 312 to the second position 23 at a lower part of the first supporting leg 2, the mast 3 is connected to the first supporting leg 2 by simultaneously connecting the second lower connecting portion 312 to the second position 23 at the lower part of the first supporting leg 2 and connecting the second upper connecting portion 311 to the first position 22 at an upper part of the first supporting leg 2, which can reduce the height of the center of gravity of the assembled structure formed by connecting the mast 3 and the first supporting leg 2, thereby improving the stability of the assembled structure formed by connecting the mast 3 and the first supporting leg 2, and in turn improving the overall stability of the forklift.

[0031] Referring to FIG. 1, in an embodiment, the first supporting leg 2 is detachably connected to the second upper connecting portion 311 on the mast 3 through a first bolt 4 in the first position 22. The first supporting leg 2 is detachably connected to the second lower connecting portion 312 on the mast 3 through a second bolt 5 in the second position 23. The first bolt 4 is horizontally disposed, and the second bolt 5 is vertically disposed.

[0032] The second connecting portion 31 on the mast 3 is located on a side of the mast 3 close to the frame 1, and the fork 32 on the mast 3 is located on a side of the mast 3 away from the frame 1. Therefore, when goods are carried by the fork 32 on the mast 3, a moment generated by the goods on the mast 3 is oriented toward the side of the mast 3 away from the frame 1, so that the second upper connecting portion 311 of the mast 3 applies a force in a horizontal direction away from the frame 1 to the first position 22 of the first supporting leg 2, and the second lower connecting portion 312 of the mast 3 applies a vertically upward force to the second position 23 of the first supporting leg 2.

[0033] The first bolt 4 detachably connecting the second upper connecting portion 311 of the mast 3 with the first position 22 on the first supporting leg 2 is horizontally disposed, and the second bolt 5 detachably connecting the second lower connecting portion 312 of the mast 3 with the second position 23 on the first supporting leg 2 is vertically disposed, so that the first bolt 4 and the second bolt 5 can bear a tensile force. Since a tensile strength of the first bolt 4 and the second bolt 5 is much greater than a shear strength of the first bolt 4 and the second bolt 5, the durability of the first bolt 4 can be improved by horizontally disposing the first bolt 4, and the durability of the second bolt 5 can be improved by vertically disposing the second bolt 5, thereby improving the durability of the connection between the mast 3 and the first supporting leg 2, and in turn improving the overall reliability of the forklift.

[0034] Exemplarily, first threaded holes may be provided at the first position 22 of the first supporting leg 2 and the second upper connecting portion 311 of the mast 3, respectively, and the first bolt 4 may pass through the first threaded holes and be threadedly engaged with the first threaded holes, so as to detachably connect the first position 22 of the first supporting leg 2 to the second upper connecting portion 311 of the mast 3.

[0035] First through holes may be provided at the first position 22 of the first supporting leg 2 and the second upper connecting portion 311 of the mast 3, respectively, and the first bolt 4 may pass through the first through holes and be threadedly engaged with a first fastening nut, so as to detachably connect the first position 22 of the first supporting leg 2 to the second upper connecting portion 311 of the mast 3.

[0036] For a connection method between the second position 23 of the first supporting leg 2 and the second lower connecting portion 312 of the mast 3, reference can be made to the connection method between the first position 22 of the first supporting leg 2 and the second upper connecting portion 311 of the mast 3.

[0037] In an embodiment, the first connecting portion on the frame 1 includes a first upper connecting portion and a first lower connecting portion (not shown in the drawings), which are vertically disposed and spaced apart from each other, and the first upper connecting portion is located above the first lower connecting portion. The frame 1 is connected to the first supporting leg 2 through the first upper connecting portion and the first lower connecting portion. The frame 1 and the mast 3 are connected to the first supporting leg 2 at different positions on a same side of the first supporting leg 2. For a specific connection method between the frame 1 and the first supporting leg 2, reference can be made to the connection method between the mast 3 and the first supporting leg 2.

[0038] Referring to FIG. 1, in an embodiment, a first connecting member 221 is provided at the first position 22 of the first supporting leg 2, and the first connecting member 221 is detachably connected to the second upper connecting portion 311 on the mast 3 through the first bolt 4. The frame 1 may also be connected to the first connecting member 221 on the first supporting leg 2 through the first upper connecting portion.

[0039] The mast 3 and the frame 1 are detachably connected to the first connecting member 221 at different positions of the first connecting member 221, which can facilitate assembly and maintenance.

[0040] In an embodiment, a limiting structure (not shown in the drawings) is further provided on a side of the frame 1 close to the mast 3. A gap may be defined between the second upper connecting portion 311 of the mast 3 and a main body of the mast 3, and the limiting structure may be located in the gap.

[0041] The second upper connecting portion 311 of the mast 3 can move in a vertical direction, and the gap between the second upper connecting portion 311 and the main body of the mast 3 is placed at the limiting structure, so that the limiting structure can be located between the second upper connecting portion 311 of the mast 3 and the main body of the mast 3.

[0042] As described above, when goods are carried by the fork 32 on the mast 3, the second upper connecting portion 311 of the mast 3 applies the force in the horizontal direction away from the frame 1 to the second position 23 of the first supporting leg 2, and since the limiting structure is located between the second upper connecting portion 311 of the mast 3 and the main body of the mast 3, the limiting structure can apply a force in the horizontal direction close to the frame 1 to the second upper connecting portion 311 of the mast 3, thereby reducing the tensile force borne by the first bolt 4 detachably connecting the second upper connecting portion 311 of the mast 3 to the first position 22 of the first supporting leg 2, and further improving the durability of the connection between the mast 3 and the first supporting leg 2.

[0043] For example, the second upper connecting portion 311 of the mast 3 may be detachably connected at the limiting structure and at the first position 22 of the first supporting leg 2 through the first bolt 4.

[0044] In an embodiment, a limiting protrusion (not shown in the drawings) is provided at a bottom of the frame 1, a limiting groove (not shown in the drawing) is correspondingly provided at a bottom of the first supporting leg 2, and the limiting protrusion is inserted into the limiting groove. In this way, the cooperation between the limiting protrusion and the limiting groove can limit movement of the frame 1 relative to the first supporting leg 2 in front-rear and left-right directions (for example, a direction toward the mast 3 can be defined as the front), so as to improve the overall reliability of the assembled structure formed by connecting the frame 1, the second supporting leg 6, and the mast 3, thereby improving the assembly reliability of the forklift.

[0045] Referring to FIG. 3, in an embodiment, the first supporting leg 2 may be replaced with a second supporting leg 6. The second supporting leg 6 may include a traveling supporting leg 61 and a telescopic supporting leg 62, and the telescopic supporting leg 62 is slidably disposed on the traveling supporting leg 61.

[0046] The second supporting leg 6 has a telescopic function, and the first supporting leg 2 does not have a telescopic function. Thus, the second supporting leg 6 and the first supporting leg 2 have different functions, that is, replacing the first supporting leg 2 with the second supporting leg 6 enables the forklift to meet the requirements for different application scenarios.

[0047] The traveling supporting leg 61 is detachably connected to the frame 1, and the mast 3 is detachably mounted on the telescopic supporting leg 62. In this way, the mast 3 can slide relative to the traveling supporting leg 61 along with the telescopic supporting leg 62, so as to move close to or away from the frame 1, thereby enabling the forklift to pick up goods in confined spaces.

[0048] Referring to FIG. 4, casters 611 are mounted at a bottom of the traveling supporting leg 61. Exemplarily, the traveling supporting leg 61 is detachably connected to the frame 1 on a first end thereof, and the casters 611 are mounted at a bottom of the traveling supporting leg 61 on a second end of the traveling supporting leg 61. In this way, the traveling supporting leg 61 can support the telescopic supporting leg 62 mounted on the traveling supporting leg 61 and cooperate with the frame 1 to realize the movement of the forklift.

[0049] Referring to FIG. 3, in an embodiment, the telescopic supporting leg 62 includes a sliding seat 621 and a vertical support 622 vertically disposed on the sliding seat 621. The sliding seat 621 is slidably disposed on the traveling supporting leg 61, and the mast 3 may be connected to the vertical support 622.

[0050] Compared with a case in which the vertical support 622 of the telescopic supporting leg 62 is directly slidably disposed on the traveling supporting leg 61, the vertical support 622 is vertically disposed on the sliding seat 621, and is slidably disposed on the traveling supporting leg 61 through the sliding seat 621, which can increase a contact area between the telescopic supporting leg 62 and the traveling supporting leg 61, thereby providing more stable support for the mast 3 connected to the telescopic supporting leg 62.

[0051] Exemplarily, slide rails 612 may be disposed on an inner side of the traveling supporting leg 61 oppositely to each other, pulleys 623 may be correspondingly disposed on an outer side of the sliding seat 621 of the telescopic supporting leg 62, and the pulleys 623 of the sliding seat 621 are located in the slide rails 612 of the traveling supporting leg 61, respectively.

[0052] Alternatively, elongated sliders may be disposed on the inner side of the traveling supporting leg 61 oppositely to each other, sliding grooves may be correspondingly disposed on the outer side of the sliding seat 621 of the telescopic supporting leg 62, and the elongated sliders of the traveling supporting leg 61 are located in the sliding grooves of the sliding seat 621, respectively.

[0053] In another embodiment, the mast 3 may be connected to the sliding seat 621 and the vertical support 622.

[0054] For a specific method in which the second supporting leg 6 is connected to the frame 1 and the mast 3, reference can be made to the specific method in which the first supporting leg 2 is connected to the frame 1 and the mast 3.

[0055] Referring to FIG. 3, in an embodiment, a limiting structure 7 is disposed at a top end of the vertical support 622 of the telescopic supporting leg 62 of the second supporting leg 6. A gap may be formed between the second upper connecting portion 311 of the mast 3 and the main body of the mast 3, and the limiting structure 7 may be located in the gap. A bottom end of the second upper connecting portion 311 of the mast 3 is supported by the top end of the vertical support 622.

[0056] The second upper connecting portion 311 of the mast 3 and the second supporting leg 6 may be detachably connected to the limiting structure 7 of the vertical support 622 of the telescopic supporting leg 62 through the second bolt 5.

[0057] Referring to FIG. 3, in an embodiment, an L-shaped frame limiting structure 8 is provided at an end of the traveling supporting leg 61 of the second supporting leg 6 close to the frame 1. A horizontal portion of the L-shaped frame limiting structure 8 is detachably fixed to the traveling supporting leg 61 through a third bolt, and a vertical portion of the L-shaped frame limiting structure 8 abuts against the frame 1. In this way, the L-shaped frame limiting structure 8 can limit the movement of the frame 1 toward the mast 3, so as to improve the overall reliability of the assembled structure formed by connecting the frame 1, the second supporting leg 6, and the mast 3, thereby improving the assembly reliability of the forklift.

[0058] Exemplarily, referring to FIG. 4, the horizontal portion and the vertical portion of the L-shaped frame limiting structure 8 may be detachably fixed to the frame through threaded members, and the horizontal portion of the L-shaped frame limiting structure 8 and the frame 1 may be detachably fixed to the traveling supporting leg 61 through the third bolt, thereby reducing the number of connecting members among the L-shaped frame limiting structure 8, the frame 1, and the traveling supporting leg 61, which facilitates assembly and maintenance.

[0059] A counterweight (not shown in the drawings) may be provided on the frame 1, and the counterweight is used to balance the weight of the goods on the fork 32. The farther a distance between the counterweight and the goods on the fork 32, the smaller the weight of the counterweight required to balance the weight of the goods with the same weight.

[0060] Referring to FIG. 5, in order to reduce the weight of the counterweight, in an embodiment, the first supporting leg 2 is replaced with a third supporting leg 9, and a connecting position between the mast 3 and the third supporting leg 9 is away from the frame 1.

[0061] The third supporting leg 9 is detachably mounted on the frame 1, the mast 3 is detachably mounted on the third supporting leg 9, and the connecting position between the mast 3 and the third supporting leg 9 is away from the frame 1, that is, the third supporting leg 9 is located between the frame 1 and the mast 3, thereby increasing a distance between the frame 1 and the mast 3, increasing the distance between the counterweight on the frame 1 and the goods on the fork 32 of the mast 3, and reducing the weight of the counterweight on the frame 1.

[0062] Referring to FIG. 6, in an embodiment, the third supporting leg 9 includes a traveling supporting leg 91. The traveling supporting leg 91 is connected to the frame 1 on a first end thereof, and casters 911 are mounted at a bottom of the traveling supporting leg 91 on a second end of the traveling supporting leg 91. In this way, the third supporting leg 9 can cooperate with the frame 1 to realize the movement of the forklift.

[0063] A bracket 92 is vertically fixedly connected to the traveling supporting leg 91. The bracket 92 is located at a position close to the second end of the traveling supporting leg 91. The mast 3 is connected to the bracket 92.

[0064] The casters 911 are mounted at the bottom of the second end of the traveling supporting leg 91, and can provide good support for the bracket 92 located close to the second end of the traveling supporting leg 91 and the mast 3 connected to the bracket 92.

[0065] For a specific method in which the third supporting leg 9 is connected to the frame 1 and the mast 3, reference can be made to the specific method in which the first supporting leg 2 is connected to the frame 1 and the mast 3.

[0066] Referring to FIG. 5, in an embodiment, a limiting structure 13 is disposed at a top end of the bracket 92 of the traveling supporting leg 91 of the third supporting leg 9. A gap may be formed between the second upper connecting portion 311 of the mast 3 and the main body of the mast 3, and the limiting structure 13 may be located in the gap. A bottom end of the second upper connecting portion 311 of the mast 3 is supported by the top end of the bracket 92.

[0067] The second upper connecting portion 311 of the mast 3 and the third supporting leg 9 can be detachably connected to the limiting structure 13 of the bracket 92 of the traveling supporting leg 91 of the third supporting leg 9 through a fourth bolt.

[0068] In an embodiment, a frame limiting member 14 is further included. The frame limiting member 14 may include a head (not shown in the drawings) and a shank, where a radial dimension of the head is greater than a radial dimension of the shank.

[0069] A limiting groove 15 is provided on an inner side of the traveling supporting leg 91 of the third supporting leg 9. The shank of the frame limiting member 14 is located in the limiting groove 15. A side of the head of the frame limiting member 14 connected to the shank abuts against an edge of the limiting groove 15, while a side of the head of the frame limiting member 14 facing away from the shank abuts against the frame 1, so that the frame limiting member 14 can limit the movement of the frame 1 toward the mast 3, thereby improving the overall reliability of the assembled structure formed by connecting the frame 1, the third supporting leg 9, and the mast 3, and improving the assembly reliability of the forklift.

[0070] Exemplarily, the shank of the frame limiting member 14 and the frame 1 may be detachably connected to the traveling supporting leg 91 of the second supporting leg 6 through a fifth screw, and the head of the frame limiting member 14 may be detachably fixed to the frame 1 through a sixth screw, thereby reducing the number of connecting members among the frame limiting member 14, the frame 1, and the traveling supporting leg 91, and facilitating assembly and maintenance.

[0071] In an embodiment, the frame 1 is provided with a first supporting leg connecting portion 10, a second supporting leg connecting portion 11, and a third supporting leg connecting portion 12. When the supporting leg is the first supporting leg 2, the first supporting leg 2 is detachably mounted on the first supporting leg connecting portion 10 on the frame 1. When the supporting leg is the second supporting leg 6, the second supporting leg 6 is detachably mounted on the second supporting leg connecting portion 11 on the frame 1. When the supporting leg is the third supporting leg 9, the third supporting leg 9 is detachably mounted on the third supporting leg connecting portion 12 on the frame 1.

[0072] The forklift provided by the embodiments of the present disclosure includes the frame 1, the supporting leg, and the mast 3, and the supporting leg is detachably mounted on the frame 1, and the mast 3 is detachably mounted on the supporting leg, which improves the ease of replacement of the supporting leg. The forklift provided by the embodiments of the present disclosure also provides the first supporting leg 2, the second supporting leg 6, and the third supporting leg 9 with different structural forms, and the first supporting leg 2, the second supporting leg 6, and the third supporting leg 9 can be assembled with the same frame 1 and mast 3. In this way, a corresponding supporting leg can be produced according to requirements, and assembled with the pre-manufactured frame 1 and mast 3 to obtain a corresponding forklift, thereby reducing the production cycle and quickly delivering to customers.

[0073] The embodiments in this specification are described in a mutually referential manner.
