Description

Technical Field

[0001] This utility model relates to the field of handling device technology, and more specifically to a dual-station quick-switching manual hydraulic handling device. Background Technology

[0002] Hydraulic handling devices are mechanical equipment or systems that utilize hydraulic energy as their power source, controlled and driven by hydraulic components such as hydraulic cylinders, hydraulic motors, valves, oil pumps, and oil tanks, for lifting, moving, positioning, tilting, or clamping loads. Currently, manually operated hydraulic handling devices exist, such as manual hydraulic forklifts or pallet jacks.

[0003] According to patent publication number CN110271992B, published on 2021-11-09, a manual hydraulic pallet truck is disclosed, including a transmission device. The transmission device includes a support column, an adjusting cable, and a fixing column. A hydraulic system is installed at the lower end of the fixing column, and a rolling device is installed at the lower end of the hydraulic system. A fixing frame is installed on one side of the rolling device, and a triangular support frame is installed on the outer surface of the fixing frame. A connecting block is installed on one side of the triangular support frame, and a protective shell is installed at the upper end of the connecting block. An LED display screen is provided at the upper end of the protective shell, and a lighting lamp is installed on one side of the protective shell. A second bearing is installed at the lower end of each end of the support frame. A sliding plate is installed at the lower end of the second bearing. A support rod is installed at the lower end of the triangular support frame. A first bearing is installed on one side of the support rod. A bolt post is installed on the outer surface of the first bearing. A threaded rod is installed on one side of the bolt post. A foot pedal is installed at one end of the second bearing. A lead screw is installed on one side of the foot pedal. A third bearing is installed on one side of the lead screw. Four sliding blocks are installed on the outer surface of the lead screw. A pressure sensor is installed on the inner side of each sliding block. A mother plate is installed at the upper end of each sliding block. A daughter plate is installed on one side of the mother plate. The mother plate and the daughter plate are connected by a connecting pin.

[0004] The aforementioned patents utilize skateboards and triangular support frames to provide a basic handling mechanism and effectively transport goods. However, these handling vehicles are mostly only suitable for palletized goods. Pallets are generally used for heavy metal goods, such as motors, machined metal parts, small metal structural components, or stacked bagged raw materials. These require cranes or manual handling before transporting using the aforementioned devices or forklifts. Lighter, manually packed goods, such as cotton wool in cardboard boxes or coiled plastic netting, are handled by manually placing the boxes onto the handling vehicle and then pulling it. However, these handling vehicles lack restraint for cardboard boxes, making them prone to falling off when turning or encountering inclines or declines. This requires several people to assist in handling, and because there is no workstation expansion or switching capability, they are not suitable for transporting pallets and cardboard boxes.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-6 The present invention provides a technical solution, including the following embodiments:

[0028] Example 1

[0029] Combination Figure 1 and Figure 2 This embodiment focuses on describing the overall structure and basic operation of the dual-station quick-switching manual hydraulic handling device.

[0030] Specifically, the top of the fork legs 11 of the hydraulic manual forklift body 1 has a first storage slot 13 along the parallel direction, with a hinged flap 4 inside; simultaneously, a second storage slot 14 is also opened on the top of the fork legs 11, with a hinged U-shaped plate 2 inside. In the storage state, the flap 4 flips over through the hinge point and fits vertically against the inner wall of the first storage slot 13, while the U-shaped plate 2 is retracted into the second storage slot 14, keeping the device compact and facilitating the fork legs 11 to lift pallets for storage and transportation. When it is necessary to switch workstations, the user can quickly operate according to the type of goods. For unpalletized cardboard boxes, the flap 4 is manually flipped out of the first storage slot 13, making it perpendicular to the top plane of the fork legs 11, forming a vertical barrier to limit the cardboard boxes from slipping; for goods that need to be guided and handled, the U-shaped plate 2 is flipped out of the second storage slot 14, with its end moving to contact the ground, forming an inclined guiding and supporting channel, facilitating the sliding of cardboard boxes and other goods to the top of the fork legs 11. The independent hinged design of the flip plate 4 and U-shaped plate 2 allows users to choose to use a single workstation or a combination of them according to actual needs, enabling rapid switching. This workstation switching speed is fast and the operation is simple and intuitive, effectively solving the problem of the single function of traditional manual hydraulic handling devices; at the same time, the storage design of the flip plate 4 and U-shaped plate 2 saves space and reduces the area occupied by the equipment.

[0031] Example 2

[0032] Combination Figure 3 and Figure 4 This embodiment details the limiting mechanism of the flap 4 and its stability optimization.

[0033] Specifically, the flap 4 is hinged to the first storage groove 13 via a second shaft 42 within the side groove 41. A second torsion spring 43 is sleeved on the outer wall of the second shaft 42, and both ends of the second torsion spring 43 are fixedly installed on the inner wall of the first storage groove 13 and the flap 4, respectively, so that the flap 4 automatically flips when unlocked. To further enhance the reliability of the limiting position, a locking rod 5 is slidably installed in the first storage groove 13. The end of the locking rod 5 is movably inserted into the locking groove 44 opened at the end of the flap 4, and is connected to the inner wall of the first storage groove 13 via a locking spring 51. When the flap 4 is in a horizontal state, the locking rod 5 automatically engages with the locking groove 44 under the action of the locking spring 51, locking the position of the flap 4 to complete the storage; when it is necessary to flip the flap 4, the user pushes the locking rod 5 to release the engagement, and the flap 4 can quickly spring up and flip with the assistance of the second torsion spring 43.

[0034] Example 3

[0035] Combination Figure 5 and Figure 6 This embodiment focuses on the formation of the guide channel of the U-shaped plate 2 and its locking system.

[0036] Specifically, the U-shaped plate 2 is hinged to the second storage groove 14 via the first shaft 22. A first torsion spring 24 is fitted onto the outer wall of the first shaft 22 to keep the U-shaped plate 2 stable during storage. A bolt 21 is threaded onto the U-shaped plate 2. By adjusting the protruding length of the bolt 21, the end of the U-shaped plate 2 can be partially blocked by the inner wall of the second storage groove 14 when it is flipped over for storage, thus keeping the U-shaped plate 2 in a nearly vertical state and forming a stable angle with the ground to cover the cardboard box. Regarding the locking mechanism, a ratchet 23 is fixedly installed on the outer wall of the first shaft 22, and a locking rod 25 is hinged to the fork 11. The locking rod 25 is movably inserted into the teeth of the ratchet 23 and provides a stable clamping force through the third torsion spring 26. When the U-shaped plate 2 flips outward, the locking lever 25 switches along the teeth of the ratchet 23. When it unfolds to the ground contact position, the ratchet 23 engages with the locking lever 25, locking the U-shaped plate 2. To unlock, the user pushes the push rod 27, which is slidably mounted on the side wall of the fork leg 11. The push rod 27 pushes open the locking lever 25, and the adjusting rod 28 at the end of the push rod 27 is threaded and rotates to protrude from the side wall of the fork leg 11. Therefore, the engagement and locking of the ratchet 23 and the locking lever 25 ensures that the U-shaped plate 2 is firmly attached to the ground during transportation, reducing the risk of slippage.

[0037] Example 4

[0038] Combination Figures 1 to 6This embodiment integrates the aforementioned design and further optimizes multifunctionality and user-friendly details.

[0039] Specifically, an alignment plate 3 is hinged to the outer wall of the adjacent side of the fork 11. The alignment plate 3 is movably stored in the third storage slot 12 opened at the top of the fork 11. When the flip plate 4 and the U-shaped plate 2 are unfolded simultaneously, the alignment plate 3 can be manually flipped out as an auxiliary alignment tool to help users accurately position goods and fill the gap between the two forks 11, thereby improving the stability of supporting the carton. The U-shaped plate 2 is made of steel plate, and the locking rod 25 is a steel rod, which enhances the overall structural strength and wear resistance. During the workstation switching process, the user can first unfold the U-shaped plate 2 to form a channel to push goods, and then erect the flip plate 4 to block it, achieving a seamless connection; when stored, all components are put into the slot, keeping the device tidy so that the two forks 11 can easily scoop up the pallet.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
