Description

Technical Field

[0001] This invention relates to the field of material handling equipment technology, and in particular to a multi-layer material handling vehicle for warehouse management. Background Technology

[0002] Handling vehicles are equipment used in warehouse management for moving goods. They are mainly used to transport goods over short distances within warehouses, workshops, and other locations to improve the efficiency of goods handling. Handling vehicles are mainly composed of components such as a frame, forks, and handles. They can be used to store goods on multi-level shelves in the warehouse.

[0003] While existing multi-level pallet trucks for warehouse management can quickly store goods on shelves of different heights, workers need to manually adjust the direction and position of the goods before placing them on the truck. This requires workers to spend a considerable amount of time preparing the goods on the ground, which not only increases labor costs but also affects the turnover rate of goods and reduces work efficiency. Therefore, we propose a multi-level pallet truck for warehouse management. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a multi-layer transport vehicle for warehouse management.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A multi-level handling vehicle for warehouse management includes:

[0007] The transport vehicle body has a lifting mechanism at one end for lifting and lowering goods, and a fork for placing goods is provided on the side of the lifting mechanism away from the transport vehicle body.

[0008] The forks are equipped with a reversing device for flipping the goods, and the forks are also equipped with a protective device for clamping the goods when they are flipped.

[0009] The reversing device includes a mounting rod fixed to the fork, a storage plate for storing goods on the mounting rod, a transmission mechanism between the storage plate and the mounting rod, and a blocking mechanism for limiting the goods at one end of the storage plate. The mounting rod has mounting holes adapted to the fork. Through the mounting holes on the mounting rod, several reversing devices can be stacked on the fork in sequence according to different needs, thereby realizing multi-layer goods transportation and transfer in a single operation. The transmission mechanism drives the storage plate to flip, causing the goods on the storage plate to flip horizontally. At the same time, the blocking mechanism blocks the goods during the flipping to prevent the goods from falling off the storage plate due to inertia.

[0010] The protective device includes a housing fixed to the fork, and a clamping mechanism inside the housing for gripping the goods when they are flipped. An adjustment mechanism that cooperates with the clamping mechanism is provided on one side of the housing. The transmission mechanism drives the movement of the blocking mechanism, which in turn drives the clamping mechanism to flip, thus fixing the goods in place and preventing them from shifting when flipped. At the same time, by adjusting the lifting mechanism, the clamping mechanism can be moved to grip the goods at different positions.

[0011] As a preferred embodiment of the present invention, the transmission mechanism includes a first threaded rod rotatably mounted on a mounting rod and two first stop rods fixed on the mounting rod. A motor for driving the first threaded rod to rotate is also fixed on the mounting rod. Two power rods are hinged between the storage plate and the mounting rod. A support plate is provided at the end of the first threaded rod and the two first stop rods away from the mounting rod. A main moving block is fixed at the bottom of the support plate, and a main threaded hole adapted to the first threaded rod is provided on the main moving block. The top of the support plate is hinged to one end of the storage plate. The two first stop rods are symmetrically arranged on both sides of the first threaded rod, and the ends of the two support plates away from the mounting rod are movably connected to the support plate. The output shaft of the motor drives the first threaded rod to rotate, causing the first threaded rod to engage with the threaded hole of the main moving block. Simultaneously, the first stop rods limit the support plate, causing the main moving block to move the support plate along the outer wall of the first threaded rod, thus moving the storage plate. The power rods limit the storage plate, causing it to flip upwards, thereby flipping the goods on the storage plate.

[0012] As a preferred embodiment of the present invention, the blocking mechanism includes two positioning blocks installed on the top of the support plate. Each positioning block is provided with a rotating shaft. One end of the storage plate is sleeved on the outer wall of the rotating shaft, and a rotating rod is rotatably connected to the middle of the rotating shaft. A feeding plate for blocking the goods is fixed at the top of the rotating rod, and the bottom of the rotating rod passes through the storage plate and is rotatably connected to the rotating shaft. When the storage plate is flipped, the storage plate drives the rotating rod to rotate, which in turn drives the feeding plate to rotate. The rotating rod and the feeding plate then cause the goods to flip, making the goods more stable when flipping.

[0013] As a preferred embodiment of the present invention, a chuck is provided at one end of the main moving block, an insert plate is fixed at the bottom of the rotating rod, the insert plate is sleeved on the outside of the rotating shaft, the rotating shaft extends through the insert plate to the outside of the positioning block, and a clamping plate is fixed on the side of the rotating rod. A second threaded rod is provided on the clamping plate, and a secondary threaded hole adapted to the second threaded rod is provided on the storage plate. A ramp is provided on the loading plate to facilitate the movement of goods. By rotating the clamping plate, the second threaded rod is engaged with the secondary threaded hole, causing the second threaded rod to separate from the storage plate. Then, the rotating rod is pushed, causing the rotating rod to drive the insert plate to rotate around the axis of the rotating shaft, causing the rotating rod to drive the secondary moving block to rotate, so that the secondary moving block and the storage plate are set on the same horizontal plane, thereby allowing the goods to be quickly moved to the storage plate via the ramp of the secondary moving block.

[0014] As a preferred embodiment of the present invention, the clamping mechanism includes a secondary clamping plate rotatably mounted inside the housing. A transmission plate is fixed to one end of the secondary clamping plate, and a slide rod is provided at the end of the transmission plate away from the secondary clamping plate. A telescopic plate is sleeved on the outer wall of the slide rod, and a groove is provided on the transmission plate to facilitate the movement of the slide rod. A guide groove adapted to the slide rod is provided on the housing, and both ends of the slide rod extend into the interior of the guide groove. A connecting shaft is provided inside the housing, and one end of the secondary clamping plate is rotatably mounted on the connecting shaft. By pushing the telescopic plate, the slide rod is moved, causing the slide rod to move along the interior of the groove. At the same time, the slide rod drives the transmission plate to move, causing the transmission plate to drive the secondary clamping plate to rotate around the axis of the connecting shaft, so that the side of the secondary clamping plate contacts the goods, thereby clamping the two sides of the goods with the secondary clamping plate, which can further improve the stability of the goods when flipping.

[0015] As a preferred embodiment of the present invention, two auxiliary moving blocks are fixed to the bottom of the support plate. A push rod is fixed to each of the two auxiliary moving blocks on opposite sides, and each of the two auxiliary moving blocks is provided with a through hole that matches the first stop rod. An inclined surface is provided at the end of the telescopic plate away from the slide rod. The auxiliary moving blocks are moved by the support plate, which in turn moves the push rod, so that the push rod contacts the inclined surface of the loading plate. The push rod and the inclined surface of the loading plate cooperate to push the loading plate to move, thereby clamping the goods when they are flipped, preventing the goods from falling from both sides of the storage plate during the flipping process, and improving the safety of the device.

[0016] As a preferred embodiment of the present invention, the adjusting mechanism includes an adjusting block disposed on the side of the secondary clamping plate away from the transmission plate. Two insert rods are fixed on the adjusting block, and a third threaded rod is screwed between the adjusting block and the secondary clamping plate. The two insert rods are disposed on both sides of the third threaded rod. The secondary clamping plate is provided with limiting holes that are adapted to the insert rods. By rotating the third threaded rod, the insert rods limit the adjustment block and the secondary clamping plate, so that the third threaded rod cooperates with the secondary clamping plate to drive the adjusting block to move, thereby increasing the distance between the adjusting block and the secondary clamping plate, so that the secondary clamping plate and the adjusting block simultaneously contact the goods, thereby clamping the goods at multiple points.

[0017] As a preferred embodiment of the present invention, a main clamping plate is fixed to the end of the adjusting block away from the insert rod, a pressure rod is fixed to the top of the main clamping plate, and a pressure ball is fixed to the end of the pressure rod away from the main clamping plate. When the auxiliary clamping plate drives the adjusting block to flip through the insert rod, the adjusting block drives the pressure rod to rotate through the main clamping plate, which in turn drives the pressure ball to rotate, so that the pressure ball comes into contact with the upper surface of the goods. This allows the goods to be limited after flipping, preventing the goods from falling off the storage plate due to inertia after flipping.

[0018] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0019] 1. The output shaft of the motor drives the first threaded rod to rotate, so that the first threaded rod engages with the threaded hole of the main moving block. At the same time, the first stop rod limits the support plate, so that the main moving block drives the support plate to move along the outer wall of the first threaded rod. The support plate drives the storage plate to move. The power rod limits the storage plate, so that the storage plate flips upward, thereby flipping the goods on the storage plate. This allows for adjustment of the direction and position of the goods during transfer or lifting, increasing the turnover speed of goods and improving work efficiency.

[0020] 2. By rotating the clamping plate, the clamping plate engages with the secondary threaded hole, causing the second threaded rod to separate from the storage plate. Then, the rotating rod is pushed, causing the insert plate to rotate around the axis of the rotating shaft. The rotating rod then drives the secondary moving block to rotate, so that the secondary moving block and the storage plate are set on the same horizontal plane. This not only allows the goods to be quickly moved to the storage plate via the ramp of the secondary moving block, but also limits the goods through the rotating rod and the secondary moving block, making the goods more stable when flipping.

[0021] 3. By pushing the telescopic plate to move the slide rod, the slide rod moves along the inside of the slide groove. At the same time, the slide rod drives the transmission plate to move, causing the transmission plate to rotate the secondary clamping plate around the axis of the connecting shaft. This causes the side of the secondary clamping plate to contact the goods, thereby clamping the goods on both sides and further improving the stability of the goods when flipping.

[0022] 4. The auxiliary moving block is driven by the support plate to move, which in turn drives the push rod to move. The push rod then contacts the inclined surface of the loading plate, and the push rod and the inclined surface of the loading plate work together to push the loading plate to move. This allows the goods to be clamped while being flipped, preventing them from falling off the sides of the loading plate during the flipping process and improving the safety of the device.

[0036] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0037] Example: The present invention provides, as follows Figure 1 A multi-level handling vehicle for warehouse management, as shown, includes:

[0038] The transport vehicle body 1 has a lifting machine 2 at one end for lifting and lowering goods, and a fork 3 for placing goods on the side of the lifting machine 2 away from the transport vehicle body 1.

[0039] As can be seen from the above, when in use, after the goods to be stored are placed on the fork 3, the goods are transported to the designated shelf by the transport vehicle body 1. Then, the fork 3 is lifted by the hoist 2 so that the goods on the fork 3 are moved to the designated shelf layer and stored.

[0040] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the fork 3 is equipped with a reversing device 4 for flipping the goods, and the fork 3 is also equipped with a protective device 5 for clamping the goods when flipping.

[0041] The reversing device 4 includes a mounting rod 406 fixed on the fork 3. A storage plate 401 for storing goods is provided on the mounting rod 406. A transmission mechanism is provided between the storage plate 401 and the mounting rod 406. A blocking mechanism for limiting the goods is provided at one end of the storage plate 401. The mounting rod 406 has mounting holes adapted to the fork 3. Through the mounting holes on the mounting rod 406, several reversing devices 4 can be stacked on the fork 3 in sequence according to different needs, thereby realizing single-time multi-layer goods transportation and transfer. The transmission mechanism drives the storage plate 401 to flip, so that the goods on the storage plate 401 are flipped horizontally. At the same time, the blocking mechanism blocks the goods during the flipping to prevent the goods from falling off the storage plate 401 due to inertia.

[0042] The protective device 5 includes a housing 501 fixed to the fork 3. Inside the housing 501 is a clamping mechanism for gripping the goods when they are flipped. On one side of the housing 501 is an adjustment mechanism that works in conjunction with the clamping mechanism. The movement of the blocking mechanism is driven by the transmission mechanism, which in turn drives the clamping mechanism to flip, thus fixing the goods in place and preventing them from shifting when flipped. At the same time, the clamping mechanism can be moved by adjusting the lifting mechanism, allowing it to grip the goods at different positions.

[0043] The transmission mechanism includes a first threaded rod 408 rotatably mounted on a mounting rod 406 and two first stop rods 409 fixed on the mounting rod 406. A motor 407 driving the first threaded rod 408 to rotate is also fixed on the mounting rod 406. Two power rods 405 are hinged between the storage plate 401 and the mounting rod 406. A support plate 403 is provided at the end of the first threaded rod 408 and the two first stop rods 409 away from the mounting rod 406. A main moving block 411 is fixed at the bottom of the support plate 403. The main moving block 411 has a main threaded hole adapted to the first threaded rod 408. The top of the support plate 403 is hinged to one end of the storage plate 401. The two first stop rods... Rods 409 are symmetrically arranged on both sides of the first threaded rod 408, and the ends of the two support plates 403 away from the mounting rod 406 are movably connected to the support plates 403. The output shaft of the motor 407 drives the first threaded rod 408 to rotate, so that the first threaded rod 408 engages with the threaded hole of the main moving block 411. At the same time, the first stop rod 409 limits the support plate 403, so that the main moving block 411 drives the support plate 403 to move along the outer wall of the first threaded rod 408, so that the support plate 403 drives the storage plate 401 to move. The power rod 405 limits the storage plate 401, so that the storage plate 401 flips upward, thereby flipping the goods on the storage plate 401.

[0044] By adopting the above technical solution:

[0045] In use, the output shaft of the motor 407 drives the first threaded rod 408 to rotate, so that the first threaded rod 408 engages with the threaded hole of the main moving block 411. At the same time, the first stop rod 409 limits the support plate 403, so that the main moving block 411 drives the support plate 403 to move along the outer wall of the first threaded rod 408, so that the support plate 403 drives the storage plate 401 to move. The power rod 405 limits the storage plate 401, so that the storage plate 401 flips upward, thereby flipping the goods on the storage plate 401. This allows the direction and position of the goods to be adjusted when transferring or lifting the goods, increasing the turnover speed of the goods and improving work efficiency.

[0046] Secondly, refer to Figure 6 and Figure 12 As shown, the blocking mechanism includes two positioning blocks 410 installed on the top of the support plate 403. Each positioning block 410 is equipped with a rotating shaft. One end of the storage plate 401 is sleeved on the outer wall of the rotating shaft, and a rotating rod 404 is rotatably connected to the middle of the rotating shaft. A feeding plate 402 for blocking the goods is fixed to the top of the rotating rod 404. The bottom of the rotating rod 404 passes through the storage plate 401 and is rotatably connected to the rotating shaft. When the storage plate 401 is flipped, the storage plate 401 drives the rotating rod 404 to rotate, which in turn drives the feeding plate 402 to rotate. This causes the rotating rod 404 and the feeding plate 402 to flip the goods, making the goods more stable when flipping.

[0047] A chuck 413 is provided at one end of the main moving block 411, and an insert plate 415 is fixed to the bottom of the rotating rod 404. The insert plate 415 is sleeved on the outside of the rotating shaft, which extends through the insert plate 415 to the outside of the positioning block 410. A clamping plate 416 is fixed to the side of the rotating rod 404, and a second threaded rod 417 is provided on the clamping plate 416. A secondary threaded hole adapted to the second threaded rod 417 is provided on the storage plate 401, and a ramp is provided on the loading plate 402 to facilitate the movement of goods. By rotating the clamping plate 416, the second threaded rod 417 engages with the auxiliary threaded hole, causing the second threaded rod 417 to separate from the storage plate 401. Then, the rotating rod 404 is pushed, causing the insert plate 415 to rotate around the axis of the rotating shaft. The rotating rod 404 then drives the auxiliary moving block 412 to rotate, so that the auxiliary moving block 412 and the storage plate 401 are set on the same horizontal plane. This allows the goods to be quickly moved onto the storage plate 401 via the ramp of the auxiliary moving block 412.

[0048] By adopting the above technical solution:

[0049] In use, by rotating the clamping plate 416, the clamping plate 416 engages with the secondary threaded hole, causing the second threaded rod 417 to separate from the storage plate 401. Then, the rotating rod 404 is pushed, causing the insert plate 415 to rotate around the axis of the rotating shaft. The rotating rod 404 drives the secondary moving block 412 to rotate, so that the secondary moving block 412 and the storage plate 401 are set on the same horizontal plane. This not only allows the goods to be quickly moved to the storage plate 401 via the ramp of the secondary moving block 412, but also limits the goods by the rotating rod 404 and the secondary moving block 412, making the goods more stable when flipping.

[0050] Again, refer to Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the clamping mechanism includes a secondary clamping plate 505 rotatably mounted inside the housing 501. A transmission plate 508 is fixed to one end of the secondary clamping plate 505. A slide rod 509 is provided at the end of the transmission plate 508 away from the secondary clamping plate 505. A telescopic plate 502 is sleeved on the outer wall of the slide rod 509, and a groove is provided on the transmission plate 508 to facilitate the movement of the slide rod 509. A guide groove 510 adapted to the slide rod 509 is provided on the housing 501, and both ends of the slide rod 509 extend into the interior of the guide groove 510. The 01 unit has a connecting shaft inside. One end of the secondary clamping plate 505 is rotatably mounted on the connecting shaft. By pushing the telescopic plate 502, the sliding rod 509 is moved, causing the sliding rod 509 to move along the inside of the slide groove. At the same time, the sliding rod 509 drives the transmission plate 508 to move, causing the transmission plate 508 to drive the secondary clamping plate 505 to rotate around the axis of the connecting shaft. This causes the side of the secondary clamping plate 505 to contact the goods, thereby clamping the two sides of the goods with the secondary clamping plate 505, which can further improve the stability of the goods when flipping.

[0051] The adjustment mechanism includes an adjustment block 511 located on the side of the secondary clamping plate 505 away from the transmission plate 508. Two insert rods 512 are fixed on the adjustment block 511, and a third threaded rod 504 is screwed between the adjustment block 511 and the secondary clamping plate 505. The two insert rods 512 are located on both sides of the third threaded rod 504. The secondary clamping plate 505 has limiting holes that match the insert rods 512. By rotating the third threaded rod 504, the insert rods 512 limit the adjustment block 511 and the secondary clamping plate 505, so that the third threaded rod 504 cooperates with the secondary clamping plate 505 to drive the adjustment block 511 to move, thereby increasing the distance between the adjustment block 511 and the secondary clamping plate 505, so that the secondary clamping plate 505 and the adjustment block 511 simultaneously contact the goods, thereby clamping the goods at multiple points.

[0052] The adjusting block 511 is fixed with a main clamping plate 503 at the end away from the insert rod 512. A pressure rod 506 is fixed to the top of the main clamping plate 503. A pressure ball 507 is fixed to the end of the pressure rod 506 away from the main clamping plate 503. When the auxiliary clamping plate 505 drives the adjusting block 511 to flip through the insert rod 512, the adjusting block 511 drives the pressure rod 506 to rotate through the main clamping plate 503. The pressure rod 506 drives the pressure ball 507 to rotate, so that the pressure ball 507 contacts the upper surface of the goods. This allows the goods to be limited after flipping, preventing the goods from falling off the storage plate 401 due to inertia after flipping.

[0053] By adopting the above technical solution:

[0054] In use, by pushing the telescopic plate 502, the slide rod 509 is moved, causing the slide rod 509 to move along the inside of the slide groove. At the same time, the slide rod 509 drives the transmission plate 508 to move, causing the transmission plate 508 to drive the auxiliary clamping plate 505 to rotate around the axis of the connecting shaft, so that the side of the auxiliary clamping plate 505 comes into contact with the goods, thereby clamping the two sides of the goods with the auxiliary clamping plate 505, which can further improve the stability of the goods when flipping.

[0055] Finally, refer to Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, two auxiliary moving blocks 412 are also fixed at the bottom of the support plate 403. Push rods 414 are fixed on opposite sides of the two auxiliary moving blocks 412, and through holes adapted to the first stop rod 409 are provided on the two auxiliary moving blocks 412. The end of the telescopic plate 502 away from the slide rod 509 is provided with an inclined surface. The support plate 403 drives the auxiliary moving blocks 412 to move, so that the auxiliary moving blocks 412 drive the push rods 414 to move, so that the push rods 414 contact the inclined surface of the loading plate 402, and the push rods 414 cooperate with the inclined surface of the loading plate 402 to push the loading plate 402 to move. Thus, when the goods are flipped, the goods are clamped at the same time to prevent the goods from falling from both sides of the storage plate 401 when flipping, thereby improving the safety of the device.

[0056] By adopting the above technical solution:

[0057] In use, the support plate 403 drives the auxiliary moving block 412 to move, which in turn drives the push rod 414 to move. The push rod 414 then contacts the inclined surface of the loading plate 402, and the push rod 414 cooperates with the inclined surface of the loading plate 402 to push the loading plate 402 to move. This allows the goods to be clamped while being flipped, preventing them from falling off the sides of the storage plate 401 during the flipping process, thus improving the safety of the device.

[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
