Description

Technical Field

[0001] This utility model relates to the field of pallet truck technology, specifically a digital warehousing pallet truck. Background Technology

[0002] With the rapid development of the logistics industry, digital warehousing has become the mainstream development direction in the modern warehousing field as an important means to improve warehousing efficiency and reduce operating costs. In digital warehousing systems, the handling and transfer of goods rely on various automated or semi-automated equipment. Among them, pallet trucks are key tools for short-distance transportation of goods pallets, and their operational stability and safety directly affect the overall efficiency of warehousing and the rate of goods loss.

[0003] However, currently, most pallet trucks on the market rely on the friction between the pallet itself and the pallet plate to fix the pallet when transporting goods. However, in actual operation, due to the complex storage environment, pallet trucks need to frequently start, brake, and turn. The goods pallet is prone to shaking, tilting, or even slipping due to inertia, which may cause safety accidents and affect the continuity and stability of storage operations.

[0004] To address these issues, we offer digital warehousing pallet trucks. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes a digital warehousing pallet truck. Through the cooperation between the pallet, the moving frame, the fixed plate, the first push rod, the threaded rod, the servo motor, the moving block, and the connecting plate, it solves the problem that current pallet trucks have poor fixation effect on the pallets when transporting goods. The goods pallets are prone to shaking, tilting, or even slipping due to the inertia generated by the movement of the pallet truck, which may cause safety accidents.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a digital warehousing pallet truck, comprising an intelligent mobile pallet truck, the intelligent mobile pallet truck comprising a base plate, a pallet disposed at the upper end of the base plate, and a cargo fixing mechanism disposed within the pallet, the cargo fixing mechanism comprising:

[0009] A movable frame, which is slidably connected within the tray;

[0010] A fixed plate, the lower end of which is connected to a rotating shaft, the rotating shaft being rotatably connected within a movable frame, and the outer end of the rotating shaft being connected to teeth;

[0011] A push rod is connected inside the movable frame. The drive end of the push rod is connected to a toothed plate, which is located at the lower end of the rotating shaft and meshes with the teeth.

[0012] A threaded rod is rotatably connected inside the support plate, and a servo motor is connected to the side end of the threaded rod;

[0013] A movable block is threadedly connected to the outer end of a threaded rod, and a connecting plate is connected to the side end of the movable block, which is connected to the side end of the movable frame.

[0014] Furthermore, the intelligent mobile cart includes multiple drive wheels connected to the lower end of the base plate, which have self-driving capability. The intelligent mobile cart also includes a protective box connected to the side end of the base plate.

[0015] Furthermore, the base plate is connected to multiple push rods of type 2, the upper drive end of each push rod is connected to the support plate, and the side end of the protective box is connected to a baffle.

[0016] Furthermore, the protective box is equipped with a controller and a hydraulic tank system, which are connected to push rod No. 1 and push rod No. 2 respectively through hydraulic pipes.

[0017] Furthermore, a support plate is connected inside the movable frame, the first push rod is located at the lower end of the support plate, and the toothed plate is slidably connected to the upper end of the support plate.

[0018] Furthermore, an action plate is connected to the side end of the fixed plate, and a pressure sensor is connected inside the fixed plate, with the pressure sensor connected to the action plate.

[0019] (iii) Beneficial effects:

[0020] Compared with existing technologies, this digital warehousing pallet truck has the following advantages:

[0021] I. This digital warehousing pallet truck is equipped with a fixed plate and a push rod. Activating the push rod causes the fixed plate to rotate around a pivot point via the action of the toothed plate and teeth. This allows the fixed plate to be adjusted to a vertical or horizontal position. In the horizontal position, the fixed plate retracts into the pallet. In the vertical position, the upper part of the fixed plate protrudes from the pallet. A threaded rod and a moving block are also included. Activating the servo motor rotates the threaded rod, which interacts with the moving block. The moving block, via a connecting plate, moves a moving frame within the pallet, thereby moving the fixed plate within the moving frame. When the fixed plate is in a vertical position, it interacts with the pallet on the upper part of the pallet, clamping the pallet between the fixed plate and the baffle. This securely fixes the pallet to the pallet, effectively preventing goods from slipping or colliding and being damaged during transportation, turning, and starting / stopping due to shaking or tilting, reducing cargo loss and ensuring the safety of warehousing operations.

[0022] Second, this digital warehousing pallet truck has a pressure sensor installed inside the fixed plate. When the action plate on the side of the fixed plate interacts with the pallet, the pressure sensor will receive a reaction force and can feed the pressure data back to the control system. The system can automatically adjust the output power of the servo motor and control the moving distance of the fixed plate according to the preset pressure threshold (such as the pressure tolerance of different goods: cardboard boxes require less clamping force to avoid deformation, while metal pallets can withstand greater force). This ensures that the clamping force is in the optimal range of "sufficiently fixed without damaging the goods". This avoids unstable goods due to excessively loose clamping and also avoids pallet deformation and goods being crushed and damaged due to excessively tight clamping. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] The push rod 8 and push rod 16 in this utility model are common hydraulic devices in the prior art, and this application will not elaborate on their models or internal structures.

[0034] like Figures 1-7 As shown, this utility model provides a technical solution: a digital warehousing pallet truck, including an intelligent mobile pallet truck 1. The intelligent mobile pallet truck 1 includes a base plate 2, with a pallet 3 disposed on the upper end of the base plate 2. The intelligent mobile pallet truck 1 includes multiple drive wheels 14, which are connected to the lower end of the base plate 2 and have self-driving capability, thereby enabling the intelligent mobile pallet truck 1 to move. The intelligent mobile pallet truck 1 includes a protective box 15, which is connected to the side of the base plate 2. A controller is disposed inside the protective box 15. The controller of the intelligent mobile pallet truck 1 integrates technologies such as the Internet of Things, artificial intelligence, and automatic control to achieve autonomous navigation, precise positioning, intelligent obstacle avoidance, and real-time interaction with a warehouse management system (WMS). By being equipped with various intelligent hardware and software systems, it can autonomously complete tasks such as picking up, placing, transporting, and docking goods in the warehousing environment. This technology has been widely used in many fields and will not be described in detail here.

[0035] The pallet 3 is equipped with a cargo fixing mechanism, which includes: a movable frame 4, a fixed plate 5, a first push rod 8, a threaded rod 10, and a movable block 12. The movable frame 4 is slidably connected inside the pallet 3 to prevent it from rotating. The lower end of the fixed plate 5 is connected to a rotating shaft 6, which is rotatably connected inside the movable frame 4. The outer end of the rotating shaft 6 is connected to a tooth 7. The first push rod 8 is connected inside the movable frame 4, and the driving end of the first push rod 8 is connected to a toothed plate 9. The toothed plate 9 is located at the lower end of the rotating shaft 6 and meshes with the tooth 7. Thus, when the first push rod 8 is activated, it will drive the fixed plate 5 to rotate around the rotating shaft 6 through the action of the toothed plate 9 and the tooth 7, thereby adjusting the fixed plate 5 to a vertical or horizontal state. The movable frame 4 is connected to a support plate 18, and the first push rod 8 is located at the lower end of the support plate 18. The toothed plate 9 is slidably connected to the upper end of the support plate 18, and the support plate 18 is used to support the toothed plate 9.

[0036] The threaded rod 10 is rotatably connected inside the support plate 3. A servo motor 11 is connected to the side end of the threaded rod 10. The moving block 12 is threadedly connected to the outer end of the threaded rod 10. A connecting plate 13 is connected to the side end of the moving block 12. The connecting plate 13 is connected to the side end of the moving frame 4. When the servo motor 11 is started, it drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 interacts with the moving block 12. The moving block 12 is used to constrain the moving frame 4, which cannot rotate, thus allowing it to move within the support plate 3.

[0037] Multiple push rods 16 are connected inside the base plate 2. The upper drive end of the push rod 16 is connected to the pallet 3. The push rod 16 is used to adjust the high end of the pallet 3, so that the device can be moved to the lower end of the cargo pallet and lifted off the ground. A baffle 17 is connected to the side of the protective box 15. A hydraulic box system is installed inside the protective box 15. It is connected to the push rod 8 and the push rod 16 through hydraulic pipes to provide power to the push rod 8 and the push rod 16.

[0038] A pressure sensor 20 is connected to the side of the fixed plate 5 and a pressure plate 19 is connected inside the fixed plate 5. The pressure sensor 20 is connected to the pressure plate 19 and can detect the pressure on the pressure plate 19 and feed the pressure data back to the control system.

[0039] Working principle: Before the device transports the cargo pallet, push rod 16 retracts and fixing plate 5 is adjusted to a horizontal position. Figure 4 As shown, the intelligent mobile pallet 1 moves to the lower end of the cargo pallet and positions the moving frame 4 at the side of the cargo pallet, causing the baffle 17 to contact the cargo pallet; then, the second push rod 16 operates to lift the pallet 3, which in turn lifts the cargo pallet off the ground; then, the first push rod 8 operates, which pushes the toothed plate 9 to move. The movement of the toothed plate 9 interacts with the teeth 7, causing the fixed plate 5 to rotate around the pivot 6, thereby adjusting the fixed plate 5 to a vertical position. Figure 5(As shown); then the servo motor 11 starts and drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 interacts with the moving block 12. The moving block 12 will drive the moving frame 4 to move within the pallet 3 through the connecting plate 13, thereby moving the fixed plate 5. The movement of the fixed plate 5 can interact with the cargo pallet at the upper end of the pallet 3, and can clamp the cargo pallet between the fixed plate 5 and the baffle 17.
