Detailed Description of the Embodiment

[0023] The following is combined with Figures 1-5 This application is described in further detail.

[0024] The present application embodiment discloses a three-way stacking electric forklift. Figures 1-5 A three-way stacking electric forklift includes a mounting seat 1, a fixing frame 2 is welded to the outer wall of the mounting seat 1, two forks 5 that move relatively synchronously are installed on the outer wall of the fixing frame 2, a spacing adjustment mechanism is installed on the outer wall of the mounting seat 1, and the spacing adjustment mechanism includes two racks 6 and a first gear 9, the two racks 6 are meshed with the first gear 9, and the first gear 9 is located between the two racks 6, and the two racks 6 are respectively welded to the outer walls of the two forks 5, and a servo motor 7 and a reducer 8 are fixedly installed on the outer wall of the mounting seat 1 on the side away from the fixing frame 2, the output shaft end of the servo motor 7 is fixedly connected to the input shaft of the reducer 8, and the output shaft of the reducer 8 is fixedly connected to the outer wall of the axis of the first gear 9 through a rotating shaft. When the output power of the servo motor 7 is decelerated by the reducer 8 and the torque is increased to drive the first gear 9 to rotate through the rotating shaft, the first gear 9 rotates and drives the two meshing racks 6 to move relatively, and at this time, the two racks 6 pull the two forks 5 to move relatively synchronously, and when the two forks 5 move closer to each other, the spacing is reduced, and when the two forks 5 move away from each other, the spacing is increased.

[0025] Reference Figure 3 and Figure 5 The outer walls of the two forks 5 are slidably connected with a movable plate 10, and sliding grooves are provided on the inner walls on both sides of the movable plate 10. The outer walls on both sides of the fork 5 are fixedly connected with sliding bars, and the sliding bars are slidably connected in the sliding grooves, so that the movable plate 10 is stably slidably connected to the fork 5. A telescopic mechanism is installed on the outer walls of the fork 5 and the movable plate 10. The telescopic mechanism includes a tooth groove 11 provided on the outer wall of the bottom of the fork 5, and a second gear 14 rotatably connected to the outer wall of the bottom of the movable plate 10 through two shaft seats 13. The second gear 14 is close to one end of the movable plate 10 facing the fixed frame 2, and an avoidance groove 12 is provided on the outer wall of the movable plate 10 directly above the second gear 14. The second gear 14 passes through the avoidance groove 12 and meshes with the tooth groove 11. A stepper motor 15 is fixedly installed on the bottom outer wall of the movable plate 10, and the end of the output shaft of the stepper motor 15 is fixedly connected to the outer wall of the axis of the second gear 14. When the stepping motor 15 drives the second gear 14 to rotate, the second gear 14 drives the movable plate 10 to slide and retract on the outer wall of the fork 5 because the tooth groove 11 is meshed with the second gear 14 .

[0026] Reference Figure 1, on both inner walls of the fixed frame 2, two limiting rods 3 are fixedly connected. A plurality of sliders 4 are slidably connected to the inner walls of the two limiting rods 3. Two forklift forks 5 are welded to the outer walls of the plurality of sliders 4. The upper and lower two sliders 4 are welded to one forklift fork 5. When the forklift fork 5 moves, it drives the slider 4 to slide on the outer wall of the limiting rod 3, playing a limiting role and enabling the forklift fork 5 to move smoothly.

[0027] Refer to Figure 1 With Figure 3 , on the bottom outer walls of both the forklift fork 5 and the movable plate 10, foot pads 16 are fixedly connected. The bottom of the foot pads 16 is lower than the bottommost parts of the second gear 14 and the stepper motor 15. When the bottom of the foot pads 16 contacts the ground, it can prevent the second gear 14 and the stepper motor 15 from contacting and rubbing against the ground, causing abnormal wear.

[0028] The implementation principle of a three-way stacking electric forklift in an embodiment of this application is as follows: During installation, the mounting seat 1 is fixed to the vehicle frame by bolts. When the forklift fork 5 stacks goods of different sizes, through the spacing adjustment mechanism, the servo motor 7 is started. The output shaft of the servo motor 7 inputs power through the input shaft of the reducer 8. The power output by the servo motor 7 is decelerated by the reducer 8 and the torque is increased, and the output shaft drives the rotating shaft to drive the first gear 9 to rotate. When the first gear 9 rotates, it drives the two racks 6 meshing with it to move relatively. At this time, the two racks 6 pull the two forklift forks 5 to move relatively and synchronously. When the two forklift forks 5 move closer to each other, the spacing is reduced. When the two forklift forks 5 move away from each other, the spacing is increased;

[0029] After the spacing is adjusted, through the telescoping mechanism, the stepper motor 15 is started. The output shaft of the stepper motor 15 drives the second gear 14 to rotate. When the stepper motor 15 drives the second gear 14 to rotate, since the tooth groove 11 meshes with the second gear 14, the second gear 14 drives the movable plate 10 to slide and telescope on the outer wall of the forklift fork 5. At this time, the overall length of the forklift fork 5 and the movable plate 10 can be adjusted. It should be noted that when the second gear 14 moves to the end of the tooth groove 11, it can be blocked by the inner wall of the tooth groove 11, playing a limiting role to prevent the movable plate 10 from detaching from the outer wall of the forklift fork 5;

[0030] In summary, when the forklift fork 5 stacks goods of different sizes, it can adjust the width and length of the forklift fork 5, so that the equipment can handle goods of different sizes, increasing the scope of application.
