Description

Technical Field

[0001] This invention relates to the field of storage pallet technology, and more particularly to a transfer pallet for storage. Background Technology

[0002] Storage pallets, also known as forklift pallets, mainly include mechanical forklift plastic pallets, rack-mounted forklift pallets, pallet jack forklift pallets, three-section forklift pallets, moisture-proof forklift pallets, as well as warehouse turnover forklift plastic pallets, plastic mats, or wooden forklift pallets. They are widely used in industries such as food, tobacco, pharmaceuticals, papermaking, hotels, printing, electronics, chemicals, clothing, textiles, warehousing, and logistics.

[0003] In the process of transporting goods in a warehouse, existing storage pallets may experience a shift in the center of gravity of the pallet when the forklift lifts it, due to reasons such as misaligned plugs or uneven ground. This can cause the pallet to tip over on the forklift, resulting in the goods falling over. To solve the above problems, this invention proposes a transfer pallet for warehousing. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that storage pallets are prone to tipping over due to center of gravity shift on the fork arms in the prior art, and to propose a transfer pallet for warehousing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A transfer pallet for warehousing includes a pallet for carrying goods and legs for supporting the pallet. The legs are fixedly disposed on the bottom surface of the pallet. A stop assembly for preventing the pallet from tipping over is fixedly disposed on the bottom of the pallet. The stop assembly includes a retractable stop and a socket. The socket is fixedly disposed on the bottom surface of the pallet, and the stop is slidably disposed on the bottom surface of the pallet. The stop can be inserted into the socket.

[0006] Preferably, the stop lever assembly further includes a housing, and a bidirectional pushing component is disposed inside the housing. The bidirectional pushing component is used to push the stop lever out of the housing or retract into the housing. The stop lever assembly further includes a unidirectional pushing component, which is used to drive the bidirectional pushing component. Two sets of unidirectional pushing components are disposed on both sides of the housing, and the two sets of unidirectional pushing components correspond to the two pushing directions of the bidirectional pushing component.

[0007] Preferably, the stop lever assembly further includes an active drive assembly and a passive drive assembly, wherein the active drive assembly is used to drive one set of unidirectional push assemblies, and the passive drive assembly is used to drive another set of unidirectional push assemblies.

[0008] Preferably, the bidirectional pushing assembly includes a sliding sleeve slidably disposed within the housing, a first push block and a second push block slidably disposed on the sliding sleeve, a first spring disposed between the first push block and the sliding sleeve, a second spring disposed between the second push block and the sliding sleeve, and a locking pin fixedly disposed on the stop rod, the locking pin being located between the first push block and the second push block.

[0009] Preferably, the bidirectional pushing assembly further includes a first locking plate and a second locking plate fixedly disposed within the housing. The inner ends of the stop rod are respectively provided with a first locking groove and a second locking groove. The first locking plate can lock the first locking groove, and the second locking plate can lock the second locking groove. The two sides of the sliding sleeve are respectively provided with a first ramp and a second ramp.

[0010] Preferably, a first push rod and a second push rod are fixedly provided on both sides of the sliding sleeve, and the one-way pushing assembly further includes a lever slidably disposed on the housing. The levers in the two sets of one-way pushing assemblies can respectively push the first push rod and the second push rod to move.

[0011] Preferably, the unidirectional pushing assembly further includes a first guide rail, a slide rod, and a cylinder. A connecting column is fixedly disposed on the cylinder, and the connecting column is rotatably connected to the slide rod. A limit block is also fixedly disposed on the slide rod, a fixing block is fixedly disposed on the connecting column, and a guide column is fixedly disposed on the slide rod at a position away from the connecting column.

[0012] Preferably, a first guide block and a second guide block are fixedly provided on both sides of the housing, the lever is slidably disposed in the cylinder, a third spring is provided between the lever and the cylinder, and a fixing post is fixedly provided in the lower middle part of the lever. The first guide block and the second guide block are used to guide the fixing post.

[0013] Preferably, the active drive component includes a first guide plate with a first guide groove, wherein a guide post of a set of unidirectional push components is located in the first guide groove, a base is fixedly disposed on the bottom surface of the support plate, a top plate is slidably disposed on the base, and the first guide plate is fixedly connected to the top plate.

[0014] Preferably, the passive drive assembly includes a second guide plate with a second guide groove. The guide post of the other set of unidirectional push assemblies is located in the second guide groove. A second guide rail is fixedly provided on the bottom surface of the support plate. The second guide plate is slidably disposed in the second guide rail. A top rod is fixedly provided at the bottom end of the second guide plate. An elastic sheet is provided between the top end of the second guide plate and the support plate.

[0015] Compared with the prior art, the present invention provides a transfer pallet for warehousing, which has the following beneficial effects.

[0016] 1. The present invention provides a stop bar assembly at the bottom of the pallet. When the forklift fork arm inserts under the pallet and lifts the pallet upward, the stop bar in the stop bar assembly can be inserted into the socket, so that the pallet and the stop bar surround the fork arm and prevent the pallet from tipping over. This solves the problem in the prior art that the storage pallet is prone to tipping over due to the shift of the center of gravity on the fork arm.

[0017] 2. The present invention, through the setting of a bidirectional pushing component, can realize the extension and retraction of the stop bar. When the stop bar is extended, it can be inserted into the socket to limit the pallet and prevent the pallet from tipping over. When the stop bar is retracted, the limit is released and it does not affect the normal lowering of the pallet by the forklift.

[0018] 3. In this invention, by setting an active drive component, when the pallet is lifted upward after the fork arm is inserted under the pallet, the active drive component can drive the corresponding one-way push component to drive the two-way push component to push out the stop bar, thereby achieving the effect of automatic limit.

[0019] 4. In this invention, by setting a passive drive component, when the fork arm lowers the pallet, the passive drive component can drive the corresponding one-way push component to drive the two-way push component to retract the stop bar, thereby achieving the effect of automatically releasing the limit and not affecting the normal lowering of the pallet by the fork arm.

[0020] 5. The present invention, through two sets of unidirectional driving components, can avoid the problem of interference between the active driving component and the passive driving component in the process of driving the bidirectional driving component.

[0021] 6. This invention, through the cooperation of the sliding sleeve, the first push block, the second push block, the first spring, and the second spring in the bidirectional pushing assembly, when the sliding sleeve moves under the action of the unidirectional pushing assembly, can use the first push block or the second push block to push the locking pin on the stop rod, thereby realizing the extension or retraction action of the stop rod. The structure is compact and the driving force is stable. At the same time, the cooperation of the first locking plate and the second locking plate with the first locking groove and the second locking groove on the stop rod can reliably lock the stop rod when it is extended to the working position or retracted to the initial position, preventing the stop rod from moving accidentally during transportation or placement, and further improving the stability and reliability of the stop rod assembly.

[0022] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0038] Please refer to Figures 1-13 A transfer pallet for warehousing includes a pallet 1 for carrying goods and support legs 2 for supporting the pallet 1. The support legs 2 are fixedly disposed on the bottom surface of the pallet 1. A stop bar assembly for preventing the pallet 1 from tipping over is fixedly disposed on the bottom of the pallet 1. The stop bar assembly includes a telescopic stop bar 6 and a socket 14. The socket 14 is fixedly disposed on the bottom surface of the pallet 1. The stop bar 6 is slidably disposed on the bottom surface of the pallet 1 and can be inserted into the socket 14.

[0039] In a specific embodiment of the present invention, the pallet 1 mainly serves to support goods. During use, goods to be transferred can be placed on the pallet 1 for transport. To improve the stability of the goods during transport, ropes or straps can be used to secure the goods to the pallet 1, preventing relative tipping between the goods and the pallet 1. In this design, four right-angle support legs 2 are provided at the bottom corner of the pallet 1, and reinforcing support legs 2 are fixedly provided at the center of each of the four sides of the pallet 1. These support legs 2 provide stable support for the pallet 1, and this arrangement facilitates the insertion of the fork arm under the pallet 1. The fork arm lifts the pallet 1; the stop lever assembly is mainly used to prevent the pallet 1 from tipping over when it is lifted by the fork arm. Specifically, when the fork arm of the forklift inserts under the pallet 1 and lifts it upward, the stop lever 6 will extend from the bottom surface of the pallet 1 and insert into the corresponding socket 14. At this time, the extended stop lever 6 cooperates with the socket 14, and the stop lever 6 is located below the fork arm, which can cooperate with the pallet 1 to limit the upper and lower movement of the fork arm and prevent the pallet 1 from tipping over. When the pallet 1 is placed in the designated position, the stop lever 6 will automatically retract. At this time, the fork arm can continue to move downward a certain distance, so that the fork arm is completely detached from the pallet 1 before being pulled out.

[0040] The stop lever assembly also includes a housing 10, within which a bidirectional pushing assembly is provided. The bidirectional pushing assembly is used to push the stop lever 6 out of or retract into the housing 10. The stop lever assembly also includes a unidirectional pushing assembly, which is used to drive the bidirectional pushing assembly. Two sets of unidirectional pushing assemblies are provided, respectively located on both sides of the housing 10. The two sets of unidirectional pushing assemblies correspond to the two pushing directions of the bidirectional pushing assembly.

[0041] Specifically, a second sliding groove 37 is provided inside the housing 10, and the stop rod 6 is slidably disposed in the second sliding groove 37, that is, the stop rod 6 can slide within the second sliding groove 37; in this solution, the bidirectional pushing component can move in two directions. When the bidirectional pushing component moves toward the socket 14, it can push the stop rod 6 out and insert the stop rod 6 into the socket 14. In this state, the stop rod 6 and the socket 14 can cooperate with the pallet 1 to limit the upper and lower movement of the fork arm and prevent the pallet 1 from tipping over; when the bidirectional pushing component moves in the opposite direction, that is, when the bidirectional pushing component moves away from the socket 14, it can push the stop rod 6 back, so that the stop rod 6 disengages from the socket 14 and retracts into the housing 10. In this state, the stop rod 6 does not affect the normal lowering of the pallet 1 by the fork arm.

[0042] Specifically, in this solution, the two sets of unidirectional pushing components correspond to the two pushing directions of the bidirectional pushing component. That is, one set of unidirectional pushing components can only push the bidirectional pushing component to move towards the socket 14, and the other set of unidirectional pushing components can only push the bidirectional pushing component to move away from the socket 14. It should be noted that the unidirectional pushing component in this solution refers to the direction in which the bidirectional pushing component can only be pushed, and does not mean that the unidirectional pushing component can only move in one direction.

[0043] The lever assembly also includes an active drive assembly and a passive drive assembly. The active drive assembly is used to drive one set of unidirectional push assemblies, and the passive drive assembly is used to drive the other set of unidirectional push assemblies.

[0044] Specifically, the one-way push component corresponding to the active drive component can extend the stop lever 6, and the one-way push component corresponding to the passive drive component can retract the stop lever 6. During use, after the fork arm is inserted under the pallet 1 and then lifted upwards, the active drive component is triggered, and the stop lever 6 extends and inserts into the socket 14, thus limiting the fork arm and preventing the pallet 1 from tipping over. After the pallet 1 is transferred to the designated position, the fork arm slowly lowers the pallet 1. When the support leg 2 on the pallet 1 touches the ground (or contacts another bearing surface), the passive drive component is triggered, and the stop lever 6 retracts, releasing the limitation on the fork arm. At this time, the fork arm can normally disengage from under the pallet 1.

[0045] The bidirectional pushing assembly includes a sliding sleeve 32 slidably disposed within the housing 10, a first push block 39 and a second push block 33 slidably disposed on the sliding sleeve 32, a first spring 30 disposed between the first push block 39 and the sliding sleeve 32, a second spring 35 disposed between the second push block 33 and the sliding sleeve 32, and a locking pin 31 fixedly disposed on the stop rod 6, the locking pin 31 being located between the first push block 39 and the second push block 33.

[0046] Specifically, a first sliding groove 36 is provided inside the housing 10, and a sliding sleeve 32 is slidably disposed in the first sliding groove 36. Two push block sliding grooves are provided on the sliding sleeve 32, and a straight groove is provided on the sliding sleeve 32. The straight groove passes through the two push block sliding grooves, and the locking pin 31 on the stop rod 6 can move in the straight groove. The first push block 39 and the second push block 33 are slidably disposed in the two push block sliding grooves respectively. The first spring 30 is located in the corresponding push block sliding groove and applies a force away from the socket 14 to the first push block 39. The second spring 35 is located in the corresponding push block sliding groove and applies a force close to the socket 14 to the second push block 33. In this scheme, the first push block 39 and the second push block 33 are both U-shaped, and the open ends of the first push block 39 and the second push block 33 are close to each other.

[0047] The bidirectional pushing assembly also includes a first locking plate 38 and a second locking plate 34 fixedly disposed inside the housing 10. A first locking groove 24 and a second locking groove 42 are respectively opened on both sides of the inner end of the stop bar 6. The first locking plate 38 can lock the first locking groove 24, and the second locking plate 34 can lock the second locking groove 42. A first ramp 40 and a second ramp 41 are respectively provided on both sides of the sliding sleeve 32.

[0048] Specifically, the first locking plate 38 and the second locking plate 34 both have a certain degree of elasticity and are mainly used to lock the first locking groove 24 and the second locking groove 42 respectively, so as to limit the stop bar 6; while the first ramp 40 can be used to push the first locking plate 38 to release the locking between the first locking plate 38 and the first locking groove 24, and the second ramp 41 can be used to push the second locking plate 34 to release the locking between the second locking plate 34 and the second locking groove 42.

[0049] When the bidirectional push assembly is in use, taking the working state as an example, the stop lever 6 is in the extended state, and the first locking plate 38 is locked in the first locking slot 24. At this time, the stop lever 6 cannot be retracted. When it is necessary to retract the stop lever 6, the sliding sleeve 32 is moved away from the socket 14. During the movement, the first push block 39 cannot move because it is blocked by the locking post 31. At this time, the sliding sleeve 32 can compress the first spring 30. When the first spring 30 is compressed to a certain range, the first ramp 40 on the sliding sleeve 32 can push the first locking plate 38, so that the first locking plate... After the first locking slot 24 is disengaged and the stop lever 6 loses its limit, the first spring 30 in its compressed state will be released instantly, pushing the stop lever 6 away. Under the action of inertia, the stop lever 6 continues to move until the locking pin 31 moves to the position of the second push block 33 and stops. At this time, the second locking slot 42 is just locked by the second locking plate 34, completing the retraction of the stop lever 6. Similarly, when the stop lever needs to be extended again, simply push the sliding sleeve 32 in the opposite direction. After pushing the sliding sleeve 32 in the opposite direction, the stop lever 6 is pushed out by the second push block 33, and then the first locking plate 38 is locked back into the first locking slot 24.

[0050] The first push rod 9 and the second push rod 20 are fixedly installed on both sides of the sliding sleeve 32. The one-way pushing assembly also includes a lever 8 slidably installed on the housing 10. The lever 8 in the two sets of one-way pushing assemblies can push the first push rod 9 and the second push rod 20 to move respectively.

[0051] The unidirectional push assembly also includes a first guide rail 11, a slide rod 19 and a cylinder 4. A connecting column 26 is fixedly installed on the cylinder 4. The connecting column 26 is rotatably connected to the slide rod 19. A limit block 25 is also fixedly installed on the slide rod 19. A fixing block 28 is fixedly installed on the connecting column 26. A guide column 18 is fixedly installed on the slide rod 19 at a position away from the connecting column 26.

[0052] Specifically, the first guide rail 11 is fixedly mounted on the housing 10, and the slide rod 19 can slide horizontally on the first guide rail 11. When the slide rod 19 moves horizontally, it can drive the cylinder 4 to move horizontally, and then drive the lever 8 to move horizontally. During a certain movement, the lever 8 can push the corresponding first push rod 9 or second push rod 20. Then, during the return stroke, the lever 8 can avoid the corresponding first push rod 9 and second push rod 20. This action is mainly achieved by the fixed block 28 and the limiting block 25.

[0053] A first guide block 7 and a second guide block 21 are fixedly installed on both sides of the housing 10, a lever 8 is slidably installed inside the cylinder 4, a third spring 29 is installed between the lever 8 and the cylinder 4, a fixed post 27 is fixedly installed in the lower middle part of the lever 8, and the first guide block 7 and the second guide block 21 are used to guide the fixed post 27.

[0054] Specifically, by setting the first guide block 7 and the second guide block 21, the height of the corresponding lever 8 can be guided respectively. When the lever 8 is not in the position of the first guide block 7 or the second guide block 21, the lever 8 can extend downward under the action of the third spring 29. At this time, the lever 8 can push the corresponding first push rod 9 or the second push rod 20. When the corresponding lever 8 is guided by the corresponding first guide block 7 or the second guide block 21, the corresponding lever 8 can move upward. At this time, the lever 8 cannot push the corresponding first push rod 9 or the second push rod 20, and the upward movement of the lever 8 does not affect the normal movement of the sliding sleeve 32. For example, the lever 8 corresponding to the first push rod 9 extends downward under the action of the third spring 29. At this time, moving the lever 8 can push the first push rod 9 to move, and then drive the sliding sleeve 32 to move. During this process, the lever 8 corresponding to the second push rod 20 is located above the second guide block 21. Therefore, when the sliding sleeve 32 moves, the lever 8 corresponding to the second push rod 20 will not interfere with the sliding sleeve 32.

[0055] The active drive component includes a first guide plate 13, on which a first guide groove 17 is provided. A guide post 18 of a set of unidirectional push components is located in the first guide groove 17. A base 5 is fixedly provided on the bottom surface of the support plate 1. A top plate 12 is slidably provided on the base 5. The first guide plate 13 is fixedly connected to the top plate 12.

[0056] Specifically, during the upward movement of the first guide plate 13, its first guide groove 17 can drive the corresponding guide post 18 to move towards the socket 14, that is, drive the corresponding lever 8 to move towards the socket 14. During the downward movement of the first guide plate 13, its first guide groove 17 can drive the corresponding guide post 18 to move away from the socket 14, that is, drive the corresponding lever 8 to move away from the socket 14.

[0057] When in use, after the fork arm is inserted into the lower position of the support plate 1, it is also located below the top plate 12. When it is lifted up, it can drive the top plate 12 to move upward first (relative to the support plate 1). During the upward movement of the top plate 12, it can drive the corresponding lever 8 to approach the socket 14, at which time the stop lever 6 can be extended.

[0058] The passive drive assembly includes a second guide plate 23, on which a second guide groove 22 is provided. The guide post 18 of another set of unidirectional push assemblies is located in the second guide groove 22. A second guide rail 15 is fixedly provided on the bottom surface of the support plate 1. The second guide plate 23 is slidably provided in the second guide rail 15. A top rod 3 is fixedly provided at the bottom end of the second guide plate 23. An elastic sheet 16 is provided between the top end of the second guide plate 23 and the support plate 1.

[0059] Specifically, as the second guide plate 23 moves upward (relative to the support plate 1), its second guide groove 22 can drive the corresponding guide post 18 to move away from the socket 14, that is, it can drive the corresponding lever 8 to push the second push rod 20 to move away from the socket 14. When the second guide plate 23 moves downward (relative to the support plate 1), it can drive the corresponding lever 8 to move closer to the socket 14.

[0060] During use, when the tray 1 is lowered, the push rod 3 first touches the ground, and then the tray 1 continues to move down. The push rod 3 drives the second guide plate 23 to move upward relative to the tray 1. At this time, the corresponding lever 8 can push the second push rod 20 away from the socket 14, and the stop rod 6 retracts.

[0061] Workflow: Taking the initial state as the working state as an example, in this working state (and the state of being off the ground), the top plate 12 is in an upward state relative to the support plate 1. At this time, the first guide plate 13 is at its highest point (relative). The fixed post 27 on the lever 8 corresponding to the first guide plate 13 is located on the first guide block 7. At the same time, the second guide plate 23 moves downward under the action of the elastic sheet 16 (moves downward relative to the support plate 1, that is, the second guide plate 23 is away from the support plate 1). The lever 8 corresponding to the second guide plate 23 is close to the socket 14, and the lever 8 is not on the corresponding second guide block 21. The lever 8 extends under the action of the corresponding third spring 29. In the above state, the sliding sleeve 32 is close to the socket 14 (that is, the first locking plate 38 is locked in the first locking groove 24, and the locking post 31 is located in the first push block 39). The stop bar 6 is in an extended state and inserted into the socket 14. This is the working state (off the ground).

[0062] When the forklift carrying pallet 1 arrives at the target location, it begins to lower pallet 1, i.e., the fork arm moves pallet 1 downwards. During this downward movement, the push rod 3 first contacts the ground (or other load-bearing surface). Since pallet 1 still has a downward tendency under the action of the fork arm, the push rod 3 is unable to continue moving downwards due to the reaction force of the ground, and pallet 1 continues to move downwards relative to the push rod 3. As pallet 1 moves downwards, the second guide rail 15 fixed to the bottom surface of pallet 1 also moves downwards. The bottom end of the second guide plate 23 is fixedly connected to the push rod 3, and the top end is connected to pallet 1 through the elastic sheet 16. Therefore, the second guide plate 23 will slide upwards relative to pallet 1. During the upward movement of the second guide plate 23, the second guide groove 22 it opens will exert a force on the guide post 18 located therein, causing the guide post 18 to move away from the socket 14. The movement of the guide post 18 then causes the slide rod 19 fixedly connected to it to slide horizontally away from the socket 14 on the first guide rail 11. The movement of the slide rod 19 further... The cylinder 4 moves synchronously via the connecting column 26, and at this time, the cylinder 4 and the connecting column 26 cannot rotate relative to each other (because of the limit block 25 and the fixing block 28). At this time, the fixing column 27 of the lever 8 corresponding to the passive drive component has not yet contacted the second guide block 21. Therefore, under the action of the third spring 29, the lever 8 extends downward, and the movement of the cylinder 4 drives the lever 8 to move away from the socket 14. During the movement, the lever 8 pushes the second push rod 20 on the sliding sleeve 32, causing the sliding sleeve 32 to slide away from the socket 14 in the first sliding groove 36. In the initial stage of the movement of the sliding sleeve 32, due to the locking column on the stop rod 6 31 is located inside the first push block 39, and the first push block 39 is blocked by the locking post 31 and cannot move with the sliding sleeve 32. Therefore, the sliding sleeve 32 will compress the first spring 30. After the sliding sleeve 32 moves a certain distance, its first ramp 40 will contact the first locking plate 38 and gradually push the first locking plate 38, causing the first locking plate 38 to disengage from the first locking groove 24 on the stop rod 6, releasing the restriction on the stop rod 6. At this time, the compressed first spring 30 releases its elastic potential energy, pushing the first push block 39. The first push block 39 then pushes the stop rod 6 away from the socket 14 through the locking post 31. The stop rod 6 slides in the second sliding groove 37 and gradually retracts. Returning to the housing 10 and disengaging from the socket 14, the locking pin 31 continues to move under the inertia of the retracted lever 6 until it contacts the second push block 33. At this time, the second locking groove 42 on the lever 6 moves to the position of the second locking plate 34, and then the second locking plate 34 locks into the second locking groove 42 to limit the retracted lever 6. After the lever 8 corresponding to the passive drive component pushes the second push rod 20 to retract the lever 6, the fixing pin 27 on the lever 8 will move the lever 8 through the second guide block 21 to avoid interference with the lever 8 when the active drive component drives the sliding sleeve 32 to move next time.As the sliding sleeve 32 moves away from the socket 14, the second push rod 20 is pushed by the lever 8. At this time, the lever 8 corresponding to the active drive component has its fixed post 27 moved upward under the guidance of the first guide block 7, so it will not interfere with the movement of the sliding sleeve 32. When the stop rod 6 is fully retracted, the fork arm can continue to move downward a certain distance, causing the top plate 12 to move downward under the action of gravity, and causing the first guide plate 13 to move downward. During the downward movement of the first guide plate 13, it can drive the lever 8 corresponding to the first guide plate 13 to move away from the socket 14, so that the lever 8 is separated from the first guide block 7 and passes through the first push rod 9 (during this process, the cylinder 4 and the sliding rod 19 are rotating). Then, at this time, the direction of the cylinder 4 is not limited by the limiting block 25 and the fixing block 28, so the lever 8 can pass normally through the first push rod 9, so that the lever 8 is finally outside the first push rod 9. That is, when the lever 8 moves towards the socket 14 again, it can push the first push rod 9 to move. When the top plate 12 moves down to the lowest point (the bottom of the base 5 is provided with a stop block, and when the top plate 12 moves down to the stop block position, it is the lowest point), the fork arm disengages from the top plate 12, and then the fork arm can be smoothly pulled out from under the support plate 1, completing the entire transfer and lowering process, and is ready to be lifted by the fork arm again. When lifted again, the fork arm first drives the top plate 12 to move up, so that the stop rod 6 extends and achieves the above working state after leaving the ground, and so on.
