Description

Technical Field

[0001] This utility model relates to the field of logistics handling, specifically a free lifting device for logistics handling. Background Technology

[0002] Logistics handling refers to a series of operations such as loading, unloading, handling, and storage that are required when moving goods from one place to another. In actual logistics transportation, due to the high mobility of goods, and the need for sorting after the goods arrive at the destination, goods destined for the same area are transported along a unified route. During the handling of goods, in order to save factory space, the goods need to be stacked. This requires the use of lifting devices, which can reduce the burden on workers and facilitate quick handling when transporting some heavy goods.

[0003] According to Chinese Patent No. CN216303151U, a lifting and handling device for logistics transportation is disclosed. This utility model can realize the lifting and handling of goods through the setting of transmission screw and connecting seat. The setting of roller can separate the goods from the support platform, so that the goods can be easily pushed to or pushed out of the support platform. Furthermore, when putting down the goods, the setting of slide can quickly and effortlessly move the goods out of the support platform, thereby reducing the workload to the greatest extent while making it convenient for people to unload the goods.

[0004] Regarding the aforementioned patent content, a support platform is provided for placing goods on the platform for lifting and lowering. The platform also includes a push plate, a lead screw, and a motor. When goods need to be pushed from the support platform onto the shelf, the operator can start the motor. The motor drives the lead screw to rotate, which in turn moves the push plate, which in turn pushes the goods onto the shelf. However, during the pushing process, the clamp does not contact the goods, resulting in a failure to guide the goods. This could cause the goods to deviate or slip off the support platform, thus reducing the efficiency of pushing the goods out. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a free lifting device for logistics handling, so as to solve the technical problem that the goods may deviate when being pushed out of the support platform, thereby affecting the efficiency of pushing out the goods.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a free lifting device for logistics handling, comprising a chassis, a scissor lift mounted on the top of the chassis, and a lifting platform on the top of the scissor lift. Slide grooves are provided on both sides of the bottom of the lifting platform, and hydraulic cylinders are installed inside the slide grooves.

A frame is fixed to the top of the connecting plate, and a rotating shaft is connected inside the frame via a bearing. A second servo motor is mounted on the top of the frame, and a worm gear extending into the frame is connected to the output end of the second servo motor. A worm wheel and a gear are respectively mounted on the outer wall of the rotating shaft. A first rack and a second rack pass through one side of the frame. A clamping plate is mounted on one side of the first rack, and a movable frame is mounted on one side of the second rack. Multiple guide rollers are rotatably mounted inside the movable frame.

[0007] By adopting the above technical solution, the guide roller can guide the goods after contacting them, preventing the goods from slipping off the lifting platform.

[0008] Furthermore, a plurality of first guide rods penetrating the frame are installed on one side of the clamping plate, and a plurality of second guide rods penetrating the frame are installed on one side of the movable frame.

[0009] By adopting the above technical solution, the second guide rod can guide the movable frame, thereby improving the stability of the movable frame when it moves.

[0010] Furthermore, a second groove is provided at the top center of the lifting platform, a first servo motor is installed on the outer surface of the lifting platform, and the output end of the first servo motor is connected to a lead screw extending into the second groove.

[0011] By adopting the above technical solution, when goods need to be pushed out, the staff can start the first servo motor, which can drive the lead screw to rotate.

[0012] Furthermore, the outer wall of the lead screw is threadedly connected to a threaded seat, and a push plate is installed on the top of the threaded seat.

[0013] By adopting the above technical solution, when the lead screw rotates, it can drive the threaded seat to move, which in turn drives the push plate to move, and the push plate can push the goods to move.

[0014] Furthermore, one end of the lead screw is connected to the second groove via a bearing, and two limiting rods are fixed to the inner wall of the second groove, with the limiting rods penetrating the threaded seat.

[0015] By adopting the above technical solution, the limiting rod can guide the threaded seat, thereby improving the stability of the threaded seat during movement and preventing the threaded seat from rotating.

[0016] Furthermore, the top two sides of the lifting platform are provided with first grooves, and multiple conveying rollers are rotatably arranged inside the first grooves.

[0017] By adopting the above technical solution, the setting of the conveyor rollers facilitates the subsequent push plate to push the goods out.

[0018] Furthermore, the bottom end of the worm is connected to the frame via a bearing, and the worm meshes with a worm wheel.

[0019] By adopting the above technical solution, when the worm rotates, it will drive the worm wheel to rotate, and the worm wheel will drive the shaft to rotate.

[0020] Furthermore, the gear meshes with the first rack and the second rack.

[0021] By adopting the above technical solution, when the gear rotates, it will drive the first rack and the second rack to move, and the direction of movement of the first rack is opposite to the direction of movement of the second rack.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A free-lifting device for logistics handling, such as Figures 1-7 As shown, the system includes a chassis 1, a scissor lift 3 mounted on top of the chassis 1, and a lifting platform 4 on top of the scissor lift 3. Slide grooves 13 are provided on both sides of the bottom of the lifting platform 4, and hydraulic cylinders 14 are installed inside the slide grooves 13. A slide block 15 is mounted on the output end of the hydraulic cylinder 14 via a piston rod. A connecting plate 16 is fixed to one side of the slide block 15, and a frame 18 is fixed to the top of the connecting plate 16. A rotating shaft 21 is connected inside the frame 18 via a bearing, and a second servo motor 19 is mounted on the top of the frame 18. The output end of 9 is connected to a worm gear 20 extending into the frame 18. The outer wall of the rotating shaft 21 is respectively equipped with a worm wheel 22 and a gear 23. A first rack 17 and a second rack 29 pass through one side of the frame 18. A clamping plate 25 is installed on one side of the first rack 17, and a movable frame 32 is installed on one side of the second rack 29. Multiple guide rollers 28 are rotatably provided inside the movable frame 32. The multiple guide rollers 28 are equidistantly distributed inside the movable frame 32. When the guide rollers 28 come into contact with the goods, they can guide the goods and prevent the goods from slipping off the lifting platform 4.

[0042] See Figures 1-5 A second groove 7 is provided at the middle of the top of the lifting platform 4. A first servo motor 11 is installed on the outer surface of the lifting platform 4, and the output end of the first servo motor 11 is connected to a lead screw 9 extending into the second groove 7. When goods need to be pushed out, the operator can start the first servo motor 11. The operation of the first servo motor 11 can drive the lead screw 9 to rotate. A threaded seat 8 is threadedly connected to the outer wall of the lead screw 9, and a push plate 12 is installed on the top of the threaded seat 8. When the lead screw 9 rotates, it can drive the threaded seat 8 to move, and the threaded seat 8 can drive the push plate 12 to move. The push plate 12 can push the goods to move. A first groove 5 is provided on both sides of the top of the lifting platform 4, and multiple conveying rollers 6 are rotatably installed inside the first groove 5. The setting of the conveying rollers 6 facilitates the subsequent push plate 12 to push out the goods. The bottom end of the worm gear 20 is connected to the frame 18 through a bearing. A through-hole 27 is provided on the clamping plate 25 and the anti-slip pad 26. The movable frame 32 passes through the through-hole 27, so that the movable frame 32 and the guide roller 28 can pass smoothly through the through-hole 27.

[0043] See Figures 1-6The worm 20 meshes with the worm wheel 22. When the worm 20 rotates, it drives the worm wheel 22 to rotate, which in turn drives the shaft 21 to rotate. The gear 23 meshes with the first rack 17 and the second rack 29. When the gear 23 rotates, it drives the first rack 17 and the second rack 29 to move. The direction of movement of the first rack 17 is opposite to that of the second rack 29. Multiple third guide rods 31 are fixed on both sides of the lifting platform 4. The third guide rods 31 pass through the connecting plate 16. The connecting plate 16 is slidably connected to the third guide rods 31. The third guide rods 31 can guide the connecting plate 16, thereby improving the stability of the connecting plate 16 when it moves. An anti-slip pad 26 is installed on one side of the clamping plate 25. Universal wheels 2 are installed around the bottom of the chassis 1. The anti-slip pad 26 is provided to improve the stability of the clamping plate 25 in holding the goods, while the universal wheels 2 are provided to facilitate the movement of the lifting device.

[0044] Example 2:

[0045] Based on the above embodiment 1, in order to improve the stability of the clamping plate 25 when it moves, it needs to be guided, so the following structure will be set.

[0046] Specifically, a plurality of first guide rods 24 penetrating the frame 18 are installed on one side of the clamping plate 25. The first guide rods 24 can guide the clamping plate 25, thereby improving the stability of the clamping plate 25 when it moves. A plurality of second guide rods 30 penetrating the frame 18 are installed on one side of the movable frame 32. The second guide rods 30 can guide the movable frame 32, thereby improving the stability of the movable frame 32 when it moves.

[0047] Example 3:

[0048] Based on the above embodiment 1, in order to improve the stability of the threaded seat 8 when it moves, it is necessary to guide the threaded seat 8, so the following structure will be set.

[0049] See Figures 1-3 One end of the lead screw 9 is connected to the second groove 7 via a bearing. Two limiting rods 10 are fixed on the inner wall of the second groove 7, and the limiting rods 10 pass through the threaded seat 8. The limiting rods 10 can guide the threaded seat 8, thereby improving the stability of the threaded seat 8 when it moves and preventing the threaded seat 8 from rotating.

[0050] The working principle of this utility model is as follows: First, the power is turned on, and then the goods are placed on the lifting platform 4. Next, the hydraulic cylinder 14 is started, causing the piston rod to retract and thus move the connecting plate 16, which in turn moves the clamping plate 25, making the clamping plate 25 contact the goods, thereby clamping and limiting the goods. Then, the hydraulic cylinder 14 is turned off, and then the scissor lift 3 is started. The operation of the scissor lift 3 can move the lifting platform 4 upward. When the lifting platform 4 rises to the designated height, the scissor lift 3 is turned off. At this time, the second servo motor 19 is started. The working drive worm 20 rotates, which in turn drives the worm wheel 22 to rotate, which in turn drives the rotating shaft 21 to rotate, and drives the gear 23 to rotate. The rotation of the gear 23 drives the first rack 17 to move away from the lifting platform 4, and at the same time drives the second rack 29 to move closer to the lifting platform 4. At this time, the movement of the first rack 17 drives the clamping plate 25 to move. The clamping plate 25 no longer contacts the goods and does not clamp the goods. Meanwhile, the second rack 29 drives the movable frame 32 to move. The movable frame 32 drives the guide roller 28 to move, so that the guide roller 28 fits against the goods in order to guide the goods.

[0051] Next, the first servo motor 11 is started. The first servo motor 11 can drive the lead screw 9 to rotate, which in turn drives the threaded seat 8 to move, and then drives the push plate 12 to move. The push plate 12 pushes the goods to move, while the guide roller 28 guides the goods to prevent them from slipping off the lifting platform 4, so that the goods can be pushed into the shelf.
