Specific embodiments

[0020] Referring to Figures 1-5 ,a warehousing forklift angle-adjustable fork includes a fork body 1. A support platform 2, a connecting frame 6 and a connecting guide rail 7 are respectively arranged on the outer side of the fork body 1. A hydraulic telescopic rod 3 and a support rod 4 are respectively fixedly connected to the inner wall of the support platform 2. A controller 5 is fixedly connected to the left side surface of the support platform 2. The hydraulic telescopic rod 3 is electrically connected to the controller 5 through a wire. The inner wall of the first rotating block 8 is rotationally hinged to the inner wall of the connecting frame 6. The inner wall of the second rotating block 10 is rotationally hinged to the inner wall of the sliding frame 9. The controller 5 can control the hydraulic telescopic rod 3 to expand and contract. Then, under the conditions that the first rotating block 8 can rotate along the inner wall of the connecting frame 6, the second rotating block 10 can rotate along the inner wall of the sliding frame 9, the support rod 4 can support the second rotating block 10, and the sliding frame 9 slides along the inside of the connecting guide rail 7, the fork body 1 can realize the adjustment of the pitching angle, playing the role of increasing the application scenario of the fork body 1 by being applicable to an inclined goods platform.

[0021] Four first fastening bolts 11 are commonly threadedly connected to the inner walls of the connecting frame 6 and the fork body 1, and six second fastening bolts 12 are commonly threadedly connected to the inner walls of the connecting guide rail 7 and the fork body 1. The first fastening bolts 11 can stably connect the connecting frame 6 and the fork body 1, and the second fastening bolts 12 can stably connect the connecting guide rail 7 and the fork body 1. Mounting frames 13 are fixedly connected to both the upper surface and the bottom surface of the support platform 2. Five mounting holes 14 are formed in the front surface of each mounting frame 13. By providing the mounting holes 14, it is possible to cooperate with external bolts to dock the mounting frame 13 with the lifting mechanism of the external forklift body, and then install the entire fork structure.

[0022] A first washer 15 is sleeved on the outer surface of each first fastening bolt 11, and the back surface of each first washer 15 is in contact with the front surface of the connecting frame 6. A second washer 16 is sleeved on the outer surface of each second fastening bolt 12, and the back surface of each second washer 16 is in contact with the front surface of the connecting guide rail 7. By providing the first washer 15 and the second washer 16, it plays a role in increasing the contact area between the two and enhancing the fastening effect of the first fastening bolt 11 and the second fastening bolt 12.

[0023] A protective shell 18 is provided outside the controller 5. The right side surface of the protective shell 18 is fixedly connected to the left side surface of the support platform 2. A protective cover 19 is movably hinged to the front surface of the protective shell 18. By providing the protective shell 18 and the protective cover 19, they can be movably hinged to each other, and can also wrap the controller 5 and provide a certain degree of protection for the controller 5. Moreover, it is convenient for the bottom of the protective shell 18 to pass through the cable so that the controller 5 can be signal- and circuit-connected to the external warehousing forklift body, thereby facilitating the control of the pitch angle of the fork body 1 by operating the external warehousing forklift body.

[0024] A fixing rod 20 is fixedly connected to the back surface of the protective shell 18, and a limiting rod 21 is fixedly connected to the back surface of the protective cover 19. By providing the fixing rod 20, it can provide a rotation base surface for other limiting structures. By providing the limiting rod 21, it can provide limitation for the above-mentioned limiting structures.

[0025] A limiting plate 22 is provided outside the protective cover 19. The inner wall of the limiting plate 22 is rotatably connected to the outer surface of the fixing rod 20, and the inside of the limiting plate 22 is clamped to the outer surface of the limiting rod 21. By providing the limiting plate 22, it can rotate around the outer surface of the fixing rod 20 and be clamped to the outer surface of the limiting rod 21, thereby being able to temporarily lock the protective shell 18 and the protective cover 19, and thus realizing better protection for the controller 5.

[0026] The inner wall of the sliding frame 9 is fixedly connected to a limiting slider 17, and the outer surface of each limiting slider 17 is slidably connected to the inside of the connecting guide rail 7. By setting the limiting slider 17, it can slide up and down along the inside of the connecting guide rail 7, thereby increasing the stability and directionality of the sliding frame 9 when sliding relative to the connecting guide rail 7.

[0027] When using this device, the connecting frame 6 and the fork body 1 are stably connected in advance with the first fastening bolt 11, and the connecting guide rail 7 and the fork body 1 are stably connected with the second fastening bolt 12. Then, the limit plate 22 is moved and rotated around the fixed rod 20, and the limit plate 22 is disengaged from the limit rod 21. Then, the protective cover 19 is opened relative to the protective shell 18, and the controller 5 is communicated and powered on with the control structure of the external warehouse forklift body by a cable. When the fork body 1 needs to adjust the pitch angle, the control structure of the external warehouse forklift body is operated to communicate with the controller 5, and then the controller 5 is connected. The hydraulic telescopic rod 3 is controlled to extend and retract, and then the first rotating block 8 rotates along the inner wall of the connecting frame 6, the second rotating block 10 rotates along the inner wall of the sliding frame 9, the support rod 4 supports the second rotating block 10, and the sliding frame 9 slides along the inside of the connecting guide rail 7. The fork body 1 can be adjusted to a pitch state of different angles, which makes it suitable for inclined cargo platforms and increases the application scenarios of the fork body 1. The design of the adjustable angle fork of the entire warehouse forklift effectively solves the problem that the fork is inconvenient to be used on inclined cargo platforms and the application scenarios are relatively limited due to the lack of a pitch adjustment structure for adjusting the pitch angle of the fork.
