[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] like Figures 1 to 4As shown in the figure, the electric pallet truck for logistics warehousing sorting in this embodiment includes a vehicle body 3. A handle 2 is installed at the top of the vehicle body 3. A lifting plate 4 is provided on the front of the vehicle body 3. A lifting frame 5 is provided on the front of the lifting plate 4. Cards 17 are movably connected to both sides of the bottom end of the lifting frame 5. Forks 7 are fixedly connected to both sides of the bottom of the front of the lifting plate 4. A notch 6 is formed at the junction of the fork 7 and the lifting plate 4. An anti-collision piece 8 is sleeved at one end of the fork 7 away from the notch 6. A standing plate 9 is fixedly connected to the bottom of the back of the vehicle body 3. A turntable 10 is provided at the bottom of the standing plate 9. A rotating shaft 11 passes through the middle of the turntable 10. Movable blocks 12 are movably sleeved at the top and bottom ends of the rotating shaft 11. An industrial buffer 13 is provided on one side of the movable block 12.
[0024] Specifically, a control system, a drive system and an internal power supply are also built into the vehicle body 3 and are electrically connected to the handle 2. At the same time, buttons for controlling the forward and backward movement and emergency stop of the pallet truck are also provided on the handle 2, so that this electric pallet truck can be used smoothly. The function of the lifting plate 4 is to lift the height where the fork 7 is located, so that the fork 7 can lift the pallet stacked with goods off the ground, thus facilitating the movement of the pallet. The lifting frame 5 is in a "冂" shape, so that the lifting frame 5 has better stability during the lifting process. At the same time, the lifting frame 5 can also drive the card 17 to pass through the notch 6, so as to realize the temporary locking of the bottom of the pallet by the card 17. The card 17 is in an "inverted v" shape and has elasticity itself. After being driven by the lifting frame 5 and inserted into the grid of the pallet, it can be embedded tightly with the pallet through its own elastic deformation, so as to realize the stability of the connection between the pallet and the fork 7 and reduce the probability of the pallet and goods sliding off the fork 7. The function of the notch 6 is to hide the card 17, so that the pallet and goods can slide smoothly to the end of the fork 7 close to the lifting plate 4, thus reducing the interference to the loading of the fork 7. The anti-collision piece 8 is in an "arc" shape, so that the end of the fork 7 is not easy to fork the pallet. The driver operating the pallet truck can stand on the standing plate 9, which is convenient for the driver to control the pallet truck. One side of the turntable 10 protrudes out of the standing plate 9. When the pallet truck is reversing, the turntable 10 will contact the object placed on the ground before the standing plate 9, so as to realize that the turntable 10 reduces the acting force generated by the collision and reduces the damage force generated after the collision. The function of the rotating shaft 11 is to enable the turntable 10 to rotate along the movable block 12 through the rotating shaft 11 by itself during the collision, so as to further consume the acting force generated by the collision and turn the rigid collision into a flexible collision, thus improving the safety of this electric pallet truck when reversing. The function of the movable block 12 is to enable the acting force received by the turntable 10 and the rotating shaft 11 to be transferred to the industrial buffer 13, so as to realize the protection of the turntable 10 by the industrial buffer 13.
[0025] Furthermore, a hydraulic cylinder 15 is fixedly installed inside the vehicle body 3, and the output end of the hydraulic cylinder 15 is fixedly connected to the top of the lifting plate 4. The lifting plate 4 is movably connected to the vehicle body 3 through the hydraulic cylinder 15. The hydraulic cylinder 15 can lift the lifting plate 4, so that the lifting plate 4 can lift the fork 7, thereby realizing the forking of the pallet.
[0026] Furthermore, an electric push rod 16 is fixedly installed inside the lifting plate 4, and the output end of the electric push rod 16 is fixedly connected to the top of the lifting frame 5. The lifting frame 5 is movably connected to the lifting plate 4 through the electric push rod 16. After the electric push rod 16 is connected to the built-in power supply of the pallet truck, the lifting frame 5 can be lifted up, so that the card 17 protrudes from the notch 6, thereby achieving the locking of the card 17 and the bottom of the pallet on the fork 7, thereby strengthening the connection between the fork 7 and the pallet.
[0027] Furthermore, a baffle 1 is fixedly connected to the top of the standing board 9, and an anti-slip pad is embedded in the middle of the top of the standing board 9. The baffle 1 can protect the driver standing on the standing board 9, thereby increasing the safety of the electric pallet truck when driving.
[0028] Furthermore, a groove is opened inside the standing board 9, and an industrial buffer 13 is installed in the groove. One end of the industrial buffer 13 is movably engaged with the movable block 12. The industrial buffer 13 can absorb the force exerted on the turntable 10 and the rotating shaft 11 after the collision, so as to reduce the collision force exerted on the standing board 9 and the vehicle body 3 and enhance the anti-collision performance of the vehicle body 3.
[0029] Furthermore, the rotating shaft 11 is movably connected to the standing board 9 through the movable block 12, and the turntable 10 is movably connected to the standing board 9 through the rotating shaft 11. The outer wall of the turntable 10 is provided with a silicone ring 14. The function of the silicone ring 14 is to protect the edge of the turntable 10 and reduce the wear caused by collision, thereby effectively extending the service life of the turntable 10.
[0030] Furthermore, the side wall of the lifting frame 5 is fixedly connected to a limit bar 18, and the function of the limit bar 18 is to limit the sliding range of the lifting frame 5 to increase the stability of the lifting frame 5 during lifting, thereby facilitating the lifting frame 5 to drive the card 17 to insert into the bottom of the pallet on the fork 7.
[0031] The method of using this embodiment is as follows: when using the electric pallet truck for logistics warehousing and sorting, the control system can be started through the handle 2, so that the control system drives the driving system to operate, so that the pallet truck travels to the pallet, and then the fork 7 is controlled to be inserted into the bottom of the pallet, and then the hydraulic cylinder 15 is started through the control system, so that the lifting plate 4 drives the fork 7 to lift, so that the pallet and the goods are erected on the fork 7, and then the electric push rod 16 is started through the control system to drive the lifting frame 5 to rise from the front of the lifting plate 4, and drive the card 17 at the bottom of the lifting frame 5 to extend from the notch 6 on the fork 7 and be stuck at the bottom of the pallet suspended on the fork 7, and then the card 17 will be inserted into the pallet The grid of the disk makes the pallet, the fork 7 and the lifting plate 4 temporarily locked, and then the vehicle body 3 can be driven to move the pallet. When the vehicle body 3 reverses and collides with an object placed on the ground, the turntable 10 will first collide with the surface of the object, and then the turntable 10 will drive the rotating shaft 11 to rotate along the movable block 12 to consume the force generated by the collision. At the same time, when the collision force is large, the rotating shaft 11 will push the movable block 12 to move toward the industrial buffer 13, so that the industrial buffer 13 absorbs the force exerted on the rotating shaft 11 and the turntable 10, so that the force exerted on the standing board 9 and the vehicle body 3 after the collision becomes smaller, thereby improving the safety of the vehicle body 3 when reversing.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
