Detailed implementation mode

[0020] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] An embodiment of the present utility model provides a forklift frame of a telescopic boom forklift, as Figure 1-2 shown, including a mounting frame 1. A plurality of groups of guiding assemblies 2 are equidistantly installed at the bottom of the mounting frame 1. A fork plate 3 is slidably arranged on each group of guiding assemblies 2. The guiding assembly 2 can guide the fork plate 3 to move along the length direction of the fork plate 3. The fork plate 3 is connected to a driving mechanism 4 for driving the fork plate 3 to slide on the guiding assembly 2. The driving mechanism 4 can drive the fork plate 3 to slide on the guiding assembly 2, so as to drive the fork plate 3 to move along the length direction of the fork plate 3, that is, it is convenient to insert the fork plate 3 under the goods or extract it from under the goods when picking up and placing goods, so as to facilitate picking up and placing goods, and improve the efficiency of picking up and placing goods.

[0022] There is no limit to the number of fork plates 3 in this embodiment. Preferably, the number of fork plates 3 is 2 to 6, and the fork plates 3 are detachably installed on the forklift frame, so that the number of fork plates 3 installed can be selected according to the needs of use.

[0023] In this embodiment, as Figure 3-4 shown, the guiding assembly 2 includes two mounting plates 21 oppositely installed at the bottom of the mounting frame 1. A roller 22 is rotatably installed between the two mounting plates 21. Rollers 23 are rotatably installed on the opposite sides of the two ends of the mounting plates 21 and below the roller 22. The fork plate 3 is arranged between the roller 22 and the rollers 23. Chutes 31 are provided along the length direction at the bottoms of both sides of the fork plate 3. The rollers 23 on the opposite sides of the two mounting plates 21 are respectively arranged inside the chutes 31 at the bottoms of both sides of the fork plate 3. With the above design, the fork plate 3 can be restricted between the roller 22 and the rollers 23, and at the same time, the fork plate 3 can be guided to move along the length direction of the fork plate 3.

[0024] It should be noted that the mounting plate 21 is provided with a rotating hole. Both ends of the roller 22 are rotatably arranged inside the rotating holes of the two mounting plates 21. At the same time, the diameter of the rotating hole is larger than the diameters of both ends of the roller 22, which enables the roller 22 to move up and down, preventing the fork plate 3 from being stuck when sliding between the roller 22 and the roller 23. At the same time, lubricating oil can be added to the rotating connection between the roller 23 and the mounting plate 21, so that the roller 23 can rotate more smoothly.

[0025] In this embodiment, the driving mechanism 4 includes a rotating shaft 411. A plurality of groups of driving gears 412 are equidistantly arranged on the rotating shaft 411. Each group of driving gears 412 includes two driving gears 412. A plurality of through holes 32 that cooperate with the driving gears 412 are equidistantly arranged on both sides of the fork plate 3. The driving gears 412 are meshed with the fork plate 3 through the through holes 32. A driven gear 413 is installed on the rotating shaft 411. The driven gear 413 is connected to a driving gear 415 through a transmission chain 414. The driving gear 415 is connected to a first driving motor 416 for driving the driving gear 415 to rotate. The first driving motor 416 is installed on the mounting frame 1. The first driving motor 416 is one of an electric motor, a hydraulic motor, or a pneumatic motor. By the first driving motor 416, the driving gear 415 can be driven to rotate. The driving gear 415 can drive the driven gear 413 to rotate through the transmission chain 414. The driven gear 413 can drive the rotating shaft 411 to rotate. The rotating shaft 411 can drive the driving gears 412 to rotate. The driving gears 412 can drive the fork plate 3 to slide on the guiding assembly 2 through the through holes 32.

[0026] In another embodiment, as Figure 5 shown, the driving mechanism 4 includes a first hinge frame 421. One end of the first hinge frame 421 is hinged to the mounting frame 1. The other end of the first hinge frame 421 is hinged to one end of a second hinge frame 422. The other end of the second hinge frame 422 is hinged to one end of the fork plate 3. The first hinge frame 421 is hinged to one end of a first telescopic device 423. The first telescopic device 423 is one of a cylinder, a hydraulic cylinder, or an electric telescopic rod. The other end of the first telescopic device 423 is hinged to the second hinge frame 422. By the first telescopic device 423, the first hinge frame 421 and the second hinge frame 422 can be driven to unfold or fold, so as to drive the fork plate 3 to slide on the guiding assembly 2.

[0027] In this embodiment, the mounting bracket 1 is hinged to one end of the mounting arm 5. One end of the mounting arm 5 is also hinged to one end of the second telescopic device 6. The second telescopic device 6 is one of a cylinder, a hydraulic cylinder or an electric telescopic rod. The other end of the second telescopic device 6 is hinged to the mounting bracket 1. The other end of the mounting arm 5 is connected to the second drive motor 7. The second drive motor 7 is one of an electric motor, a hydraulic motor or a pneumatic motor. The second drive motor 7 is mounted on the mounting seat 8. The mounting seat 8 is rotatably connected to the first connecting frame 9. The first connecting frame 9 is mounted on the telescopic arm of the telescopic forklift. The mounting seat 8 is hinged to one end of the third telescopic device 10. The third telescopic device 10 is one of a cylinder, a hydraulic cylinder or an electric telescopic rod. The other end of the third telescopic device 10 is hinged to the second connecting frame 11. The second connecting frame 11 is mounted on the forklift arm of the telescopic forklift. By means of the second telescopic device 6, the mounting bracket 1 can be driven to rotate around one end of the mounting arm 2, so that the fork plate 3 can swing up and down. By means of the second drive motor 8, the mounting arm 5 can be driven to rotate (360-degree rotation), so that the fork plate 3 can be driven to rotate. By means of the third telescopic device 10, the mounting seat 8 can be driven to rotate around the rotation connection between the mounting seat 8 and the first connecting frame 9, so that the fork plate 3 can swing left and right, so that the fork plate 3 can be inserted into the bottom of the goods or withdrawn from the bottom of the goods in all directions, thereby further facilitating the picking and placing of goods, that is, the efficiency of picking and placing goods can be further improved.

[0028] Specific principle: When in use, the fork plate 3 is driven to rotate by the second drive motor 7, and the fork plate 3 is driven to swing up and down and left and right by the second telescopic device 6 and the third telescopic device 10, so that the fork plate 3 faces the bottom of the goods. After the adjustment is completed, the fork plate 3 is driven to move along the length direction of the fork plate 3 by the drive mechanism 4, and the fork plate 3 is inserted into the bottom of the goods. When the fork plate 3 is inserted into the bottom of the goods, the telescopic forklift lifts the goods and transports the goods to the designated position. When the goods are transported to the designated position, the fork plate 3 is driven to move in the reverse direction by the drive mechanism 4, and the fork plate 3 is withdrawn from the bottom of the goods. The efficiency of picking and placing goods is high.

[0029] The forklift frame of the telescopic forklift in this embodiment can be used in cooperation with the ground lifting plate 12 for placing goods when in use. Slots 121 matching the fork plate 3 are provided at the top and bottom of the ground lifting plate to facilitate the lifting of the fork plate 3 by the ground lifting plate 12.
