Description

Technical Field

[0001] This invention relates to the field of forklifts, and in particular to an adapter for wide-spacing side forklifts. Background Technology

[0002] With the rapid development of my country's industry, the warehousing and logistics industry has also developed rapidly. Forklifts are an indispensable piece of equipment in warehousing and logistics. Common forklifts have their forks at the front of the vehicle body, making them flexible in operation and widely used.

[0003] When storing long, narrow materials such as timber, steel, and pipes, they are typically placed parallel to the aisle along their length. The aisles are often too narrow for the materials, making front-load forklifts unsuitable. Sidecar forklifts, with forks mounted on the side and a cargo platform on the side, are more suitable in this environment. However, some long, narrow structures allow for fixed fork positions with large spacing, which common sidecar forklifts cannot accommodate. A common solution is to use pallets to lift the entire material, then use a forklift to pick up the pallet. However, equipping each item with a pallet is costly, and the pallets must be returned after transport, making the process cumbersome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a large-spacing side forklift adapter to solve the problems of high cost and cumbersome process of side forklifts picking up long strip materials with large spacing between fork positions mentioned in the background art.

[0005] This invention relates to a large-pitch side forklift adapter, including a mast, on which two material forks are slidably mounted. Both material forks are located on the same side of the mast, and one of the material forks can slide along the mast towards or away from the other material fork. A locking member is provided between the material fork and the mast to lock the material fork onto the mast. A forklift fork docking sleeve is also fixedly mounted on the mast.

[0006] The present invention relates to a large-pitch side forklift adapter, wherein the material forks are provided with grooves, and the mast is provided with strip-shaped protrusions that match the shape of the grooves. The material forks are slidably mounted on the strip-shaped protrusions of the mast through the grooves.

[0007] The present invention relates to a large-pitch side forklift adapter, wherein the locking element includes two locking blocks and multiple slots provided on a strip-shaped protrusion. The multiple slots are arranged at intervals along the length direction of the strip-shaped protrusion, and the two locking blocks are respectively engaged in the slots on opposite sides of the material fork.

[0008] This invention relates to a large-pitch side forklift adapter, wherein the mast includes an upper strip plate and a lower strip plate. The upper strip plate is located above and parallel to the lower strip plate. The upper and lower strip plates are fixedly connected by a vertical connecting plate. The grooves on the material forks include upper and lower grooves. The strip protrusions on the mast include upper and lower strip protrusions. The upper and lower strip protrusions match the shapes of the upper and lower grooves, respectively. The upper strip plate has upper strip protrusions arranged along its length on its upper sides at both ends, and the lower strip plate has lower strip protrusions arranged along its length on its lower sides at both ends. One material fork slides on the upper and lower strip protrusions at one end of the upper and lower strip plates via its own upper and lower grooves, respectively. The other material fork slides on the upper and lower strip protrusions at the other end of the upper and lower strip plates, respectively, via its own upper and lower grooves, respectively.

[0009] The present invention relates to a large-pitch side forklift adapter, wherein the upper strip-shaped protrusion is provided with multiple slots, and the multiple slots are arranged at intervals along the length direction of the upper strip-shaped protrusion.

[0010] The present invention relates to a large-pitch side forklift adapter, wherein the material fork includes a fixedly connected vertical fork arm and a horizontal fork arm, the vertical fork arm and the horizontal fork arm together forming an L-shape, and the side of the vertical fork arm away from the horizontal fork arm is provided with an upper groove and a lower groove.

[0011] The present invention relates to a large-pitch side forklift adapter, wherein a forklift fork docking sleeve is fixedly provided on the lower strip plate, the forklift fork docking sleeve is located in the middle of two material forks, and the height of the forklift fork docking sleeve is lower than that of the two material forks.

[0012] The present invention relates to a large-pitch side forklift adapter, wherein the locking block is provided with an anti-drop groove, and the anti-drop groove is engaged with the bottom of the slot.

[0013] The present invention relates to a large-pitch side forklift adapter, wherein the lower connecting plate has a downwardly extending protrusion in the lower center, the forklift fork coupling sleeve is fixedly connected to the protrusion, and the forklift fork coupling sleeve and the material fork are both located on the same side of the mast.

[0014] The present invention relates to a large-pitch side forklift adapter, wherein the lower strip protrusions on the lower sides of the two ends of the lower strip plate are respectively located on opposite sides of the protrusion.

[0015] The difference between this invention's large-spacing side forklift adapter and existing technologies lies in its operation. In this invention, the forks of the side forklift are inserted into the forklift fork coupling sleeve on the adapter. This fixes the adapter to the forklift forks, allowing the adapter to move synchronously with the forklift forks. The distance between the two forklift forks is then adjusted according to the two forklift positions of the long, narrow material, ensuring a one-to-one correspondence between the two forklift forks and the two forklift positions. A locking mechanism then secures the two forks to the mast. Finally, the forklift forks are driven to engage the two forklift forks on the adapter, allowing the material to be transported. Therefore, this invention is suitable for long, narrow materials with large forklift position spacing by adjusting the distance between the two forks, and it is applicable to long, narrow materials with varying forklift position spacings. It is low-cost and easy to operate.

[0016] The invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0038] like Figure 1 As shown, and in combination Figure 2-15As shown, the large-pitch side forklift adapter of the present invention includes a mast 01, on which two material forks 06 are slidably mounted. The two material forks 06 are located on the same side of the mast 01. One of the material forks 06 can slide along the mast 01 to move closer to or further away from the other material fork 06. A locking member is provided between the material fork 06 and the mast 01. The locking member can lock the material fork 06 onto the mast 01. A forklift fork coupling sleeve 09 is also fixedly mounted on the mast 01.

[0039] Each material fork 06 is equipped with a locking device between itself and the mast 01. The two material forks 06 can be locked onto the mast 01 by the locking device, that is, the material forks 06 are fixed onto the mast 01.

[0040] like Figure 3-5 As shown in Figures 6-7 and 10-13, the large-pitch side forklift adapter of the present invention includes a material fork 06 with a groove, and a strip-shaped protrusion matching the shape of the groove fixed on the mast 01. The material fork 06 slides on the strip-shaped protrusion of the mast 01 through the groove, thus achieving the sliding mounting of the material fork 06 on the mast 01. Each material fork 06 has a groove, and two material forks 06 slide on the strip-shaped protrusion (the strip-shaped protrusion is located within the groove) through their own groove, thus achieving the sliding mounting of two material forks 06 on the mast 01. Each material fork 06 can slide closer to or further away from the other material fork 06 along the strip-shaped protrusion through its own groove, thus achieving the sliding of one of the two material forks 06 along the mast 01 closer to or further away from the other material fork 06.

[0041] like Figure 1 , 2 As shown in Figures 6-15, the large-pitch side forklift adapter of the present invention includes a locking member comprising two locking blocks 10 and a plurality of slots 11 provided on a strip-shaped protrusion. The plurality of slots 11 are evenly spaced along the length direction of the strip-shaped protrusion. The two locking blocks 10 are respectively engaged in the slots 11 on opposite sides of the material fork 06. As described above, each material fork 06 is locked to the mast 01 by a locking member, and the two locking members have the same structure. For each material fork 06, the two locking blocks 10 of the locking member are respectively engaged in the slots 11 on opposite sides of the material fork 06. After the locking blocks 10 are engaged in the slots 11, the height of the locking blocks 10 is higher than the height of the strip-shaped protrusion but lower than the height of the material fork 06, and the two locking blocks 10 abut against the opposite sides of the material fork 06, so that the material fork 06 can no longer slide along the strip-shaped protrusion, thus locking the material fork 06 to the mast 01.

[0042] like Figure 1-15As shown, the present invention relates to a large-pitch side forklift adapter frame, wherein the mast 01 includes an upper strip plate 02 and a lower strip plate 04. The upper strip plate 02 is located above and parallel to the lower strip plate 04. The upper strip plate 02 and the lower strip plate 04 are fixedly connected by multiple mutually spaced vertical connecting plates 03. The upper strip plate 02, the lower strip plate 04, and the vertical connecting plates 03 are integrally formed to form the mast 01. The grooves on the material forks 06 include upper grooves and lower grooves 14. The strip protrusions on the mast 01 include upper strip protrusions 12 and lower strip protrusions 13. The upper strip protrusions 12 and lower strip protrusions 13 are respectively matched with the shapes of the upper grooves and lower grooves 14. The upper strip plate 02 has upper strip-shaped protrusions 12 arranged along its length on its upper sides at both ends, and the lower strip plate 04 has lower strip-shaped protrusions 13 arranged along its length on its lower sides at both ends. One material fork 06 is slidably mounted on the upper strip-shaped protrusions 12 and 13 at one end of the upper strip plate 02 and lower strip plate 04 via its upper and lower grooves 14, respectively. The other material fork 06 is slidably mounted on the upper strip-shaped protrusions 12 and 13 at the other end of the upper strip plate 02 and lower strip plate 04 via its upper and lower grooves 14, respectively.

[0043] Both the upper strip plate 02 and the lower strip plate 04 are arranged vertically, thus the overall plate-like mast is also arranged vertically. Since the upper strip plate 02 is parallel to the lower strip plate 04, the upper strip protrusion 12 is arranged along the length of the upper strip plate 02, and the lower strip protrusion 13 is arranged along the length of the lower strip plate 04. Therefore, the upper strip protrusion 12 is parallel to the lower strip protrusion 13, and the material fork 06 can slide along the upper strip protrusion 12 and the lower strip protrusion 13 respectively through its upper and lower grooves 14.

[0044] One material fork 06 can slide along the upper strip protrusion 12 and lower strip protrusion 13 at one end of the upper strip plate 02 and lower strip plate 04, that is, the material fork 06 can slide along the length direction of the upper strip plate 02 and lower strip plate 04. The other material fork 06 can slide along the upper strip protrusion 12 and lower strip protrusion 13 at the other end of the upper strip plate 02 and lower strip plate 04, that is, the material fork 06 can slide along the length direction of the upper strip plate 02 and lower strip plate 04. In other words, each material fork 06, while sliding along the length direction of the upper strip plate 02 and lower strip plate 04, can move closer to or further away from the other material fork 06.

[0045] like Figure 1 , 2As shown in Figures 6-13, the large-pitch side forklift adapter of the present invention has multiple slots 11 on the upper strip-shaped protrusion 12, and the multiple slots 11 are evenly spaced along the length direction of the upper strip-shaped protrusion 12. For each upper strip-shaped protrusion 12, there are multiple slots 11, and the multiple slots 11 and two locking blocks 10 constitute a locking member, which can be used to lock a material fork 06 onto the mast 01.

[0046] like Figure 1 , 3 As shown in Figures 6, 8, 10, and 12, the large-pitch side forklift adapter of the present invention includes a material fork 06 comprising a fixedly connected vertical fork arm 07 and a horizontal fork arm 08, which together form an L-shape. The vertical fork arm 07 has an upper groove and a lower groove 14 on the side away from the horizontal fork arm 08. The vertical fork arm 07 is arranged vertically, and the horizontal fork arm 08 is arranged horizontally. The horizontal fork arm 08 is located at the lower end of the vertical fork arm 07, and the horizontal fork arm 08 and the upper / lower grooves 14 are located on opposite sides of the vertical fork arm 07. After the material fork 06 slides on the upper strip protrusion 12 and the lower strip protrusion 13 via its upper and lower grooves 14, the vertical fork arm 07 is parallel to both the upper strip plate 02 and the lower strip plate 04. That is, when the material fork 06 slides along the length of the upper and lower strip plates 04, the vertical fork arm 07 always remains parallel to the upper and lower strip plates 04. Since the horizontal fork arm 08 and the upper / lower grooves 14 are located on opposite sides of the vertical fork arm 07, the horizontal fork arm 08 extends vertically away from the vertical fork arm 07, that is, it extends vertically away from the mast 01.

[0047] like Figure 1 , 3 As shown in Figures 6, 8, 10, and 12, the large-pitch side forklift adapter frame of the present invention includes a forklift fork docking sleeve 09 fixedly mounted on the lower strip plate 04. The forklift fork docking sleeve 09 is located in the middle of two material forks 06, and its height is lower than that of the two material forks 06. The forklift fork docking sleeve 09 has a sleeve structure and is arranged correspondingly to the forks 18 of the side forklift 16. Typically, there are two forklift forks 18, and therefore two forklift fork docking sleeves 09. Each forklift fork docking sleeve 09 corresponds one-to-one with the two forklift forks 18. The shape of each forklift fork docking sleeve 09 matches the shape of its corresponding forklift fork 18. When the forklift fork 18 is inserted into the corresponding forklift fork docking sleeve 09, the two are tightly connected, allowing the adapter frame to move synchronously with the forklift forks 18. Of course, the forklift fork docking sleeves 09 can be arranged according to the actual number of forklift forks 18.

[0048] like Figure 14 , 15As shown, in the large-pitch side forklift adapter of the present invention, the locking block 10 is provided with an anti-drop groove 15, which is engaged with the bottom of the slot 11. Figure 2 , 4 As shown in Figures 7, 9, 11, and 13, if the anti-drop groove 15 is not provided, when the locking block 10 is engaged in the slot 11 (i.e., the locking block 10 is inserted into the slot 11), although the locking block 10 can prevent the material fork 06 from sliding on the mast 01, during the movement of the adapter frame following the fork 18 of the side forklift 16, since the slot 11 passes through the upper strip protrusion 12 perpendicular to the length of the upper strip protrusion 12, the locking block 10 can easily slip off the slot 11, which in turn causes the material fork 06 to slide back and forth on the mast 01 and become unusable. After the anti-drop groove 15 is set, the locking block 10 is inserted into the slot 11. The anti-drop groove 15 can be engaged with the bottom of the slot 11, that is, the bottom of the slot 11 enters the anti-drop groove 15. In this way, when the adapter moves with the forks 18 of the side forklift 16, the locking block 10 will not slip off the slot 11, thus ensuring that the material forks 06 are fixed on the mast 01.

[0049] like Figure 1 , 3 As shown in Figures 6, 8, 10, and 12, the large-pitch side forklift adapter of the present invention has a downwardly extending protrusion 05 on the lower center of the lower connecting plate. The forklift fork coupling sleeve 09 is fixedly connected to the protrusion 05, and both the forklift fork coupling sleeve 09 and the material fork 06 are located on the same side of the mast 01. The lower strip-shaped protrusions 13 on the lower sides of both ends of the lower strip plate 04 are located on opposite sides of the protrusion 05.

[0050] There are two lower strip-shaped protrusions 13, which are located on opposite sides of the protrusion 05. There is one upper strip-shaped protrusion 12, which extends from one end of the upper strip plate 02 to the other end, thus achieving the purpose of having upper strip-shaped protrusions 12 on the upper sides of both ends of the upper strip plate 02.

[0051] Since the two lower strip protrusions 13 are located on opposite sides of the protrusion 05, the two material forks 06 are also located on opposite sides of the protrusion 05. The forklift fork coupling sleeve 09 is also arranged in a direction perpendicular to the mast 01, that is, the forklift fork coupling sleeve 09 is parallel to the horizontal fork arm 08 of the material fork 06 (both are arranged in a horizontal direction), and the height of the forklift fork coupling sleeve 09 is lower than the horizontal fork arm 08. Since the horizontal fork arm 08 is located at the lower end of the vertical fork arm 07, the height of the forklift fork coupling sleeve 09 is lower than the entire material fork 06. In this way, after the fork 18 of the side forklift 16 is inserted into the forklift fork coupling sleeve 09, when picking up the material 19, only two material forks 06 are used to pick up (or only two material forks 06 are used to support the material 19). That is, when picking up the material 19, the material fork 06 abuts against the bottom of the material 19. Since the height of the forklift fork coupling sleeve 09 is lower than the material fork 06, the forklift fork coupling sleeve 09 does not contact the material 19.

[0052] like Figure 16-19 As shown, the difference between the large-pitch side forklift adapter of the present invention and the prior art is that, in use, the forks 18 of the side forklift 16 are inserted into the forklift fork coupling sleeve 09 on the adapter. This tightly connects and fixes the adapter to the forklift forks 18, meaning the adapter can move synchronously with the forklift forks 18. Then, the distance between the two material forks 06 is adjusted according to the two fork positions 20 of the long strip material 19, allowing the two material forks 06 to move along the mast 0. 1. Slide the forks 06 to adjust the distance between them, aligning them one-to-one with the two fork positions 20. Then, lock the two forks 06 onto the mast 01 using locking devices. Specifically, insert locking blocks 10 into the slots 11 on opposite sides of the forks 06. Then, drive the forklift forks 18 to move, allowing the two forks 06 of the adapter to insert into the two fork positions 20 of the elongated material 19. At this point, the two forks 06 are in contact with the bottom of the material 19, enabling transport of the material 19. Therefore, this invention can be applied to elongated materials 19 with large fork position 20 spacing by adjusting the distance between the two forks 06, and it can also be applied to elongated materials 19 with different fork position 20 spacings. It is low-cost and easy to operate.

[0053] The two forklift fork coupling sleeves 09 are located between the two material forks 06. That is to say, the distance between the two material forks 06 is greater than the distance between the two forklift fork coupling sleeves 09, which is greater than the distance between the two forks 18 of the side forklift 16. In this way, the forklift spacing of the side forklift 16 is greatly expanded by the adapter, so it can forklift long strip materials 19 with a large spacing at the forklift position 20.

[0054] Both the upper strip protrusion 12 and the lower strip protrusion 13 are trapezoidal protrusions. The upper groove and the lower groove 14 of the material fork 06 are also trapezoidal grooves. The grooves of the material fork 06 match the strip protrusions of the mast 01. That is, the shape of the upper groove matches the shape of the upper strip protrusion 12 (the upper strip protrusion 12 is located in the upper groove), and the shape of the lower groove 14 matches the shape of the lower strip protrusion 13 (the lower strip protrusion 13 is located in the lower groove 14).

[0055] The mast 01 and the forklift fork coupling sleeve 09 are welded together as a whole. The material fork 06 is recessed and inserted into the strip protrusion of the mast 01, allowing adjustment within a certain range at both ends of the mast 01. After the position is fixed, the detachable locking block 10 is inserted into the slot 11 of the mast 01 to secure the material fork 06. Conversely, when it is necessary to adjust the position of the material fork 06 again, the locking block 10 can be removed from the slot 11, and then the material fork 06 can be moved along the mast 01. After the position of the material fork 06 is adjusted, the locking block 10 is inserted into the slot 11 again to fix the position of the material fork 06.

[0056] When in use, first align the groove of the material fork 06 with the strip protrusion of the mast 01, slide it to the appropriate position, and then insert the detachable locking block 10 into the slot 11 of the mast 01. The material forks 06 at both ends of the mast 01 are arranged symmetrically about the center of the mast 01.

[0057] When picking up material 19, the material forks 06 of the transfer frame come into contact with the forklift position 20 of material 19. The picked-up material 19 can be placed on the cargo platform 17 of the side forklift 16.

[0058] The beneficial effects of this invention are as follows:

[0059] (1) The present invention does not change the structure of the side forklift 16 itself, and can realize the forklift loading of long strip materials 19 by only one adapter frame. Compared with the traditional form of setting pallets at the bottom of each material 19, the cost is much cheaper.

[0060] (2) The present invention has a simple structure, and each component can be customized and replaced according to requirements.

[0061] (3) In this invention, the position of the material fork 06 on the mast 01 can be adjusted within a certain range, which can adapt to materials 19 with different fork spacing.
