[0043] Reference Figures 1-6 A multi-functional forklift mast includes a forklift body 1, a mast portion 11 mounted on the forklift body 1, a cross plate 111 on the mast portion 11, a loading assembly 2 on the cross plate 111, and a first push rod component 21. The first push rod component 21 is a pneumatic or hydraulic push rod as used in the prior art. The first push rod component 21 is mounted on the cross plate 111. A slide table 22 is mounted on the piston end of the first push rod component 21. A support plate 23 is mounted on the slide table 22. The support plate 23 is provided with a receiving groove 231. A bidirectional screw 24 is rotatably mounted in the receiving groove 231. One end of the bidirectional screw 24 extends to the outside of the receiving groove 231 and is connected to a drive motor 241. The drive motor 241 is a servo drive motor as used in the prior art, which can provide power for the rotation of the bidirectional screw 24.

[0044] Both ends of the bidirectional screw 24 are equipped with bearing seats 25. The two ends of the bidirectional screw 24 have symmetrical threads. By installing the bearing seats 25 on the two sets of threads respectively, the bearing seats 25 can be brought closer or further apart. The bearing seat 25 has an extension plate 251. The extension plate 251 is provided with a clamping component 26. The clamping component 26 includes a storage seat 261. The storage seat 261 has an inclined end 2611. The inclined end 2611 allows the storage seat 261 to have an inclined angle for loading round goods. The two sets of storage seats 261 form a clamping area for placement. The clamping component 26 is used to clamp the round goods.

[0045] The mast section 11 also has two sets of spaced-apart fork plate members 3. The fork plate members 3 can perform loading operations on conventional goods. Guide rails 31 are provided on both sides of the fork plate members 3. Limiting components 4 are movably arranged on the guide rails 31. The limiting components 4 include slides 41 and baffles 42. Two sets of slides 41 are provided and are movably arranged on the guide rails 31 respectively. The baffles 42 are arranged on the two sets of slides 41. The baffles 42 and the fork plate members 3 are vertically distributed. The baffles 42 and the fork plate members 3 can form a limiting area for the goods. The guide rails 31 can realize the installation or removal of the limiting components 4 on the fork plate members 3.

[0046] Based on the above structure, when a ring-shaped cargo needs to be loaded, the slide table 22 is moved by the cooperation of the first push rod component 21, causing the support plate 23 to move synchronously with the clamping component 26 until the bottom end face of the storage seat 261 mounted on the extension plate 251 in the clamping component 26 abuts against the ground. Then, according to the size of the cargo, the rotation of the bidirectional screw 24 is controlled by the drive motor 241, causing the bearing seat 25 to move the storage seat 261. During the movement, the two sets of storage seats 261 move closer or further apart, and with the cooperation of the forklift body 1, the cargo can be positioned between the two sets of storage seats 261. Then, the storage seat 261 moves further apart by the rotation of the bidirectional screw 24. 261 clamps the goods between both sides and adjusts their position through the cooperation of the first push rod component 21. The fork plate component 3 can load part of the goods at the same time, thereby improving the loading flexibility. Since the fork plate component 3 is equipped with a limit component 4, when the goods are on the fork plate component 3, the slide 41 drives the baffle 42 to move along the guide rail 31, so that the goods are located between the baffle 42 and the end face of the fork plate component 3, thereby limiting the goods and improving the stability of the goods during loading. Through the cooperation of the loading component 2, the flexibility and adaptability of the forklift during loading can be improved, solving the problem that the existing forklifts can only load rectangular goods, resulting in a single loading function.

[0047] In one embodiment, reference is made to Figures 1-4 The support plate 23 is also provided with a fixing component 5, which includes a mounting plate 51. The mounting plate 51 is vertically mounted on the support plate 23. A second push rod component 52 is provided on the mounting plate 51. The second push rod component 52 can be a pneumatic push rod or a hydraulic push rod in the prior art. The piston end of the second push rod component 52 passes through the mounting plate 51 and is mounted with a pad 53.

[0048] The pad 53 is located between the two sets of storage seats 261. The pad 53 is located on top of the goods and clamps the three end faces of the goods with the cooperation of the two sets of storage seats 261. Since the pad 53 is installed on the second push rod component 52, the pad 53 can be moved to change position through the cooperation of the second push rod component 52, so that it can be used for materials of different sizes and heights.

[0049] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6The clamping component 26 also includes a turntable 262. An extension plate 251 has a shaft, and the turntable 262 is sleeved on the shaft. The turntable 262 is rotatably mounted on the extension plate 251. A storage seat 261 is located on the side of the turntable 262 away from the extension plate 251. When the turntable 262 rotates along the circumferential direction of the shaft, the storage seat 261 rotates synchronously. When the turntable 262 rotates along the shaft, it can drive the storage seat 261 to rotate synchronously. Since there are two sets of storage seats 261, the angle of one or both sets of turntables 262 can be adjusted according to the size and shape of the goods to be loaded, thereby enabling the forklift to load goods of different sizes and shapes, and increasing the flexibility of the clamping component 26.

[0050] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 6 The fork plate 3 has several grooves 32 spaced apart along its length. A pulley component 6 is installed within each groove 32. The pulley component 6 includes a support rod 61, with both ends connected to the inner walls of the grooves 32. Roller components 62 are fitted onto the support rod 61, with portions of the roller components 62 located outside the grooves 32. The cooperation between the roller components 62 and the support rod 61 allows the roller components 62 to rotate freely around the support rod 61. When the fork plate 3 is loading goods, the roller components 62 reduce friction as the goods move onto the fork plate 3, facilitating rapid loading and improving loading efficiency.

[0051] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 7 The pad 53 is provided with a slot 531 that penetrates the pad 53. Several slots 531 are provided and are spaced apart along the length of the pad 53. The pad 53 is made of rubber.

[0052] The protective pad 53 has an arc-shaped end 532. The arc-shaped end 532 facilitates the clamping and fitting of the pad 53 with cylindrical goods. The multiple slots 531 improve the extensibility and deformation of the pad 53, so that the pad 53 can fit with the end face of goods of different shapes when it is fixed.

[0053] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6The extension plate 251 has a through hole that penetrates through the extension plate 251. The through hole is located in a single position. The turntable part 262 is provided with mounting holes 2621. When the mounting holes 2621 and the through holes are aligned, the mounting holes 2621 and the through holes are interconnected. Several mounting holes 2621 are provided and are evenly distributed along the circumference of the turntable part 262. The mounting holes 2621 and the through holes have the same diameter. When one set of mounting holes 2621 is aligned with the through holes, a pin is connected between the mounting holes 2621 and the through holes. The arrangement of several mounting holes 2621 allows the turntable part 262 to be aligned with the through holes when it rotates to different angles. The fact that the holes have the same diameter makes it easy for the pin to pass through the mounting holes 2621 and the through holes. When the pin passes through the mounting holes 2621 and the through holes, it can limit the turntable part 262, thereby preventing the turntable part 262 from rotating when holding goods.

[0054] In one embodiment, reference is made to Figures 1-4 The support plate 23 is also provided with a slide groove 232, and a guide rod 2321 is provided in the slide groove 232. A traction seat 252 is provided on the side of the extension plate 251 facing the slide groove 232. The traction seat 252 is sleeved on the guide rod 2321. When the bearing seat 25 moves in position with the cooperation of the bidirectional screw 24, the traction seat 252 moves synchronously along the length direction of the guide rod 2321. The traction seat 252 can guide the movement path, thereby improving the stability of the movement of the bearing seat 25.

[0055] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The mounting plate 51 has fixing holes 511 on both sides. The support plate 23 has threaded holes 233 at the positions corresponding to the fixing holes 511. When the threaded holes 233 and the fixing holes 511 are aligned, bolts are threaded onto the threaded holes 233. The bolts pass through the fixing holes 511. The mounting plate 51 can be installed or removed from the support plate 23 by means of threaded connection, thereby enabling flexible installation of the fixing component 5 and avoiding the situation where the fixing component 5 restricts the goods when the size of the goods is too large, thus improving the flexibility of the installation of the fixing component 5.

[0056] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 An anti-slip pad 2612 is provided on the inclined end 2611. The anti-slip pad 2612 is made of rubber. The inclined end 2611 is the side that the storage seat 261 directly contacts. Therefore, by providing the anti-slip pad 2612 on the inclined end 2611, the friction of the storage seat 261 when in contact can be increased, thereby preventing slippage during clamping.
