[0028] See Figure 1 and Figure 2 As shown, an embodiment of a skewer attachment structure for a large-tonnage forklift is shown, which includes a fork frame 1, in which a fork shaft 2 and a distance-adjusting cylinder 11 are installed; a skewer attachment 6 connected to the fork shaft 2, the skewer attachment 6 having a pestle-shaped rod 62; a fork sleeve 3 is provided between the skewer attachment 6 and the fork shaft 2; and a sheath 8 is detachably provided on the pestle-shaped rod 62.

[0029] In this embodiment, both ends of the string rod attachment 6 respectively have fixed ends 61 for connecting to the fork shaft 2. The fixed end 61 is provided with an assembly hole 611 for the fork shaft 2 to pass through. The assembly hole 611 is provided with a bushing 5.

[0030] In this embodiment, a baffle 4 is further sleeved on the fork shaft 2 , and the baffle 4 contacts the side of the fixed end 61 .

[0031] In this embodiment, the structure of the fork sleeve 3 matches the fixed end 61 and is sleeved on the fixed end 61 , and the baffle 4 is located between the fork sleeve 3 and the fixed end 61 .

[0032] In this embodiment, the fork shaft 2 passes through the fork sleeve 3, the fixed end 61, the baffle 4 and the bushing 5, and one end of the fork shaft 2 is inserted into and fixed in the fork frame 1, and the other end of the fork shaft 2 is fixed on the outside of the fork frame 1 through the shaft baffle 10.

[0033] In this embodiment, a threaded hole 621 is provided at one end of the pestle-shaped rod 62 away from the string rod attachment 6, and a through hole 81 is provided at the position corresponding to the threaded hole 621. The pestle-shaped rod 62 and the sheath 8 are connected by a bolt 7 passing through the through hole 81 and screwed into the threaded hole 621. The sheath 8 is a nylon sheath.

[0034] In this embodiment, the dimensional matching structure between the fork sleeve 3, the fixed end 61, the baffle 4, the bushing 5 and the fork shaft 2 satisfies that the string rod attachment 6 does not move in the axial direction of the fork shaft 2 when the forklift is working.

[0035] In this embodiment, the fork frame 1 includes two mounting parts A, and the two fixed ends of the string rod attachment 6 are respectively connected to the two mounting parts A. A fork shaft 2 can be detachably mounted in each mounting part A.

[0036] The following description will further explain the characteristics and functions of the present invention.

[0037] This embodiment discloses a skewer attachment structure for a large-tonnage forklift, including a fork frame 1, a fork shaft 2, a fork sleeve 3, a baffle 4, a bushing 5, a skewer attachment 6, a bolt 7, a nylon sheath 8, a fork 9, a shaft baffle 10, a distance adjustment cylinder 11, etc. Figure 1 shown.

[0038] This embodiment is illustrated by taking the assembly of a 16T large-tonnage forklift skewer attachment as an example. The skewer attachment 6 is mainly used to fork tubular cargo of about 16 tons. Since the cargo is too heavy, in order to avoid wear and damage to the rod when forking the cargo, the surface of the pestle-shaped rod 62 of the skewer attachment 6 is covered with a wear-resistant nylon protective sleeve 8 to protect the surface of the rod and increase the service life of the skewer attachment 6. A threaded hole 621 is processed on the front end face of the pestle-shaped rod 62 of the skewer attachment 6, and a through hole 81 is formed at the beginning of the sleeve 8. The sleeve 8 is fixed to the surface of the pestle-shaped rod 62 of the skewer attachment 6 by a bolt 7.

[0039] The mating surface between the skewer attachment 6 and the fork shaft 2 is equipped with a wear-resistant bushing 5, with both ends of the bushing 5 sealed by a baffle 4 to prevent the bushing 5 from falling off during use. The skewer attachment 6 is assembled and fixed to the fork frame 1 through the fork shaft 2. The ends of the skewer attachment 6 pass through the fork shaft 2 and are equipped with fork sleeves 3, which are assembled on the outside of the fixed end. The adjustable cylinder 11 is fixed to the fork frame 1 with its own bolts at one end and fixed to the two fork sleeves 3 at the other end to prevent the skewer attachment 6 from moving left or right during use.

[0040] After the skewer attachment 6 is assembled on the fork frame 1 through the fork shaft 2, the fork shaft 2 is fixed to the fork frame 1 at both ends using shaft stops 10 and bolts to prevent the fork shaft 2 from moving left or right during use. With this simple assembly method, the skewer attachment 6 can be installed on the forklift.

[0041] When there is no need to fork the tubular goods, the string rod attachment 6 can be easily interchanged with the fork 9 (such as Figure 1 The interchange is accomplished by removing the shaft baffles 10 at both ends of the fork frame 1, taking out the fork shaft 2, removing the skewer attachment 6, and replacing it with the fork 9. Repeating the disassembly steps in reverse completes the interchange between the skewer attachment 6 and the fork 9. This is a simple and convenient operation that requires no additional large equipment.

[0042] To sum up, the skewer attachment of the large-tonnage forklift with a skewer attachment structure of the utility model can easily solve the needs of forking and carrying tubular goods, effectively improving the overall handling efficiency. At the same time, the attachment can also be interchangeable with ordinary conventional forks to meet the needs of carrying goods of different shapes, increase the applicable scenarios of forklifts, improve the production efficiency of enterprises, reduce the demand for users' forklifts, and reduce the cost of use.

[0043] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
