Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forklifts, in particular to a three-way forklift for warehouse goods handling. BACKGROUND

[0002] The three-way forklift, also known as a three-way stacking forklift, is a mechanical device that can stack or take goods in front of the vehicle and on either side of the vehicle during operation. It is commonly used in warehouses, logistics centers and other places. The existing three-way forklift includes a lifting structure, a translation structure and a rotation structure, so that the forks can rotate 180 degrees and move left and right, thereby achieving the stacking and taking of goods on both sides, and there is no need to frequently adjust the position of the vehicle body. Therefore, the design of the three-way forklift enables it to operate efficiently in very narrow spaces, greatly improving the storage efficiency and operational flexibility of the warehouse.

[0003] However, the existing three-way forklift still has some defects in use: first, when handling goods, the forks are used to insert and lift the goods, and there is no other device to fix the goods. If the goods are large, there is a risk of instability and falling during handling. Second, when the forks with goods are moved horizontally, they are usually moved from one side of the forklift to the other side to achieve the transfer of goods between the two sides of the forklift. Since the forks and goods move a large amount during horizontal movement, if the goods are heavy, the overall center of gravity of the forklift will shift, causing the forklift to tilt. Since the three-way forklift is usually used in narrow aisles, the tilting of the forklift may touch the shelves on one side, causing the shelves to vibrate and the goods to fall, and in severe cases, it may even cause the shelves to collapse. SUMMARY

[0004] The present application proposes a three-way forklift for warehouse goods handling, which effectively improves the stability of goods handling and effectively stabilizes the center of gravity of the three-way forklift, to solve the problem of goods falling due to unstable setting during work, and the problem of the three-way forklift tilting due to the shift of the center of gravity during work.

DETAILED DESCRIPTION

[0071] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0072] Embodiment one, a three-way forklift for warehouse cargo carrying, as shown in Figure 1 , Figure 5This includes a loading plate 51, one side of which is fixedly connected to a loading ring 52. The loading ring 52 is designed to provide a connection point for fixing the loading mechanism 5 and the rotating mechanism 4. Two forks 53 are fixedly connected to the other side of the loading plate 51. The forks 53 are L-shaped and symmetrically arranged, facilitating the insertion and removal of the cargo assembly 50. Figure 8 The cargo assembly 50 is placed on the forks 53, and the cargo assembly 50 includes a placement seat 501 and a cargo box 502. The placement seat 501 is inverted U-shape, and the cargo box 502 is placed above the placement seat 501, providing convenience for the forks 53 to move the cargo assembly 50. Figure 5 , Figure 8-10 , Figure 12-13 A movable component 6 is provided above the two forks 53 to adsorb the cargo component 50, thereby enhancing the stability of the cargo component 50 during handling. One end of the movable component 6 is connected to the support component 9 to provide power for the adsorption function of the movable component 6.

[0073] like Figure 9-10 , Figure 12-13 The moving component 6 includes a moving plate 61 and an air pipe 62. The moving plate 61 is movably mounted on the forks 53, and the length of the moving plate 61 is greater than the distance between the two forks 53, which allows the moving plate 61 to be stably placed on the forks 53 and to fully fit with the cargo component 50. The moving plate 61 has three moving cavities inside, which are arranged vertically in a linear fashion. The side of the moving plate 61 closest to the cargo component 50 has three sets of suction holes, and each set of suction holes corresponds to one moving cavity, which can provide suction space for the moving plate 61 to absorb the cargo component 50. The side of the moving plate 61 away from the cargo component 50 is fixedly provided with an air pipe 62. One end of the air pipe 62 is connected to the three moving cavities of the moving plate 61, and the other end of the air pipe 62 is connected to the support component 9. The air pipe 62 can be used to connect the moving plate 61 to the support component 9, thereby providing conditions for the support component 9 to control the air pressure inside the moving plate 61.

[0074] Therefore, the carrying mechanism 5 consists of a carrying plate 51, a carrying ring 52, a fork 53, a moving component 6, and a supporting component 9. The fork 53 is used to move the cargo component 50, and during the moving process, the moving component 6 is used to attract and fix the cargo component 50, which effectively reduces the shaking amplitude of the cargo component 50, improves the stability of the cargo component 50 during handling, and reduces the risk of the cargo component 50 falling due to instability during handling.

[0075] Example 2, based on Example 1, such as Figure 9-10 , Figure 12-13The moving component 6 also includes a movable component 8. The moving plates 61 located on both sides of the moving cavity have moving grooves inside, and the moving grooves are connected to the moving cavity. The moving plates 61 are movably connected to the movable component 8 through the moving cavity and the moving grooves, which are used to provide auxiliary effects for the moving plates 61. They can effectively limit the movement of the moving plates 61 on the forks 53, improve the stability of the movement of the moving plates 61, and gradually reduce the adsorption effect of the moving plates 61 on the cargo components 50 when the cargo components 50 are completely detached from the forks 53, preventing the sudden removal of the suction force from affecting the placement of the cargo components 50, and further improving the stability of the cargo components 50 during handling. In addition, the up and down movement of the movable component 8 in the moving plates 61 effectively cleans the moving cavity of the moving plates 61, prevents dust and impurities from clogging it, and extends the service life of the moving plates 61.

[0076] like Figure 13The movable component 8 includes a movable vertical rod 81, a movable horizontal rod 82, and a movable block 83. The movable vertical rod 81 is movably sleeved in the movable groove of the movable plate 61. The lower half of the fork 53 has a movable groove at its top, with the area of ​​the movable groove near the end of the fork 53 angled downwards and the area of ​​the movable groove not near the end of the fork 53 horizontally positioned. The movable groove not only restricts the movement of the movable component 6 on the fork 53, making the movable component 6 more stable, but also provides conditions for the up-and-down movement of the movable component 8 within the movable component 6. The upper end of the movable vertical rod 81 is connected to the movable plate 61. The movable plate 61 is connected to the movable slot wall by a movable spring, which provides a pushing force for the downward movement of the movable vertical rod 81. The lower end of the movable vertical rod 81 passes through the movable plate 61 and is movably engaged with the movable slot of the fork 53. When the movable vertical rod 81 is in the horizontal area of ​​the movable slot, the portion of the movable vertical rod 81 extending out of the movable plate 61 is small, and the movable spring is in a compressed state. When the movable vertical rod 81 moves in the downward-sloping area of ​​the movable slot, the portion of the movable vertical rod 81 extending out of the movable plate 61 increases, and the movable spring is in a stretched state. The two ends of the movable crossbar 82 are respectively connected to two movable... The vertical rod 81 is fixedly connected, and there are three movable horizontal rods 82, with each movable horizontal rod 82 located in a moving cavity. When the movable vertical rod 81 is in the horizontal area of ​​the movable groove, the movable horizontal rod 82 is located in the upper half of the moving cavity, that is, above the adsorption hole. When the movable vertical rod 81 moves in the downward-sloping area of ​​the movable groove, the movable horizontal rod 82 moves to the lower half of the moving cavity, thereby making the height of the movable horizontal rod 82 flush with the adsorption hole. The outer wall of the movable horizontal rod 82 is fixedly sleeved with a movable block 83, and the two sides of the movable block 83 are flush with the inner wall of the moving plate 61. The movable block 83 has fine bristles on its outer wall to effectively clean the moving cavity of the moving plate 61. The movable block 83 corresponds one-to-one with the adsorption hole, and the diameter of the movable block 83 is larger than the diameter of the adsorption hole, which provides the conditions for the movable block 83 to seal the adsorption hole. When the movable vertical rod 81 is located in the horizontal area of ​​the movable groove, the movable block 83 is located in the upper half of the moving cavity, that is, the movable block 83 does not seal the adsorption hole. When the movable vertical rod 81 moves in the downward inclined area of ​​the movable groove, the movable block 83 moves to the lower half of the moving cavity, thereby achieving the sealing of the adsorption hole by the movable block 83.

[0077] Example 3, based on Example 2, such as Figure 5 , Figure 8-11 The loading mechanism 5 also includes a pushing component 7, which provides power to move the moving component 6. As the forks 53 unload the cargo component 50, the loading plate 51 carries the forks 53 backward. At this time, the moving plate 61 is always in contact with the cargo component 50 under the control of the pushing component 7, effectively protecting the cargo component 50 and further improving the stability of the cargo component 50 during handling.

[0078] like Figure 11, the pushing component 7 includes a pusher 71, a first push plate 72, a rotating member 73, a second push plate 74, and a pushing frame 75. The pusher 71 is composed of several cross-shaped members, and the cross-shaped members are movable. By controlling the change of the included angle of the cross-shaped members, the length of the pusher 71 can be effectively changed, enabling the pusher 71 to have a telescopic function. The pusher 71 is made of a lightweight and non-deformable material, such as aluminum-magnesium alloy, which can effectively reduce its own weight, so that the pusher 71 will not droop when extended. One end of the pusher 71 is movably hinged to the first push plate 72, and the number of the first push plates 72 is two. The rotating member 73 is composed of a rotating motor and a rotating screw, and the rotating motor is movably connected to the rotating screw. The rotating motor is fixedly embedded in the carrier plate 51. A vertical groove is provided in the middle of the carrier plate 51, and the carrier plate 51 is movably sleeved with the rotating screw through the vertical groove, so that the rotating motor can drive the rotating screw to rotate in the vertical groove. Two groups of thread grooves are provided on the outer wall of the rotating screw, and the directions of the two groups of thread grooves are opposite. The two first push plates 72 are respectively threadedly sleeved in the two groups of thread grooves of the rotating member 73, and the first push plates 72 are movably clamped in the vertical groove of the carrier plate 51. When the rotating motor drives the rotating screw to rotate forward, the two first push plates 72 can be driven to move towards each other, thereby stretching the pusher 71. When the rotating motor drives the rotating screw to rotate backward, the two first push plates 72 can be driven to move away from each other, thereby contracting the pusher 71. The other end of the pusher 71 is movably hinged to the second push plate 74, and the number of the second push plates 74 is two. A pushing frame 75 is fixedly connected to one side wall surface of the moving plate 61. Two long grooves are provided inside the pushing frame 75, and the shape of the long grooves is "convex". The two second push plates 74 are respectively movably clamped in the two long grooves of the pushing frame 75. When the pusher 71 is stretched, the two second push plates 74 move towards each other in the long grooves. When the pusher 71 is contracted, the two second push plates 74 move away from each other in the long grooves.

[0079] Embodiment 4. On the basis of Embodiment 3, a three-way forklift for warehouse goods handling, such as Figure 1-8 , further includes a driving vehicle 1, a lifting mechanism 2, a translation plate 3, and a rotating mechanism 4. A control device is provided at the rear half of the top of the driving vehicle 1, and the control device can control the driving vehicle 1 to run in the warehouse, thereby realizing the handling of the goods component 50. A lifting mechanism 2 is provided at the front half of the top of the driving vehicle 1, which is used to control the lifting of the translation plate 3, the rotating mechanism 4, and the loading mechanism 5. One side of the translation plate 3 is connected to the lifting mechanism 2. A tooth groove is provided on the other side of the translation plate 3, and the translation plate 3 is meshed with the rotating mechanism 4 through the tooth groove, which is used to control the translation of the rotating mechanism 4 and the loading mechanism 5. Limiting grooves are provided at the top and bottom of the translation plate 3, which are used to enhance the stability of the connection between the translation plate 3 and the rotating mechanism 4. The rotating mechanism 4 is fixedly connected to the loading mechanism 5, which is used to control the rotation of the loading mechanism 5.

One end of the first hydraulic rod 24 is movably connected to the first hydraulic cylinder 23, and the other end of the first hydraulic rod 24 is fixedly connected to the top of the placement groove of the lifting plate 22. The first hydraulic cylinder 23 can control the vertical movement of the first hydraulic rod 24, thereby causing the lifting plate 22 to move up and down along the lifting groove of the lifting frame 21, thus achieving lifting... The lifting plate 22 is raised and lowered by two fixed brackets 25 fixedly connected to one side of the lifting plate 22. The two fixed brackets 25 are symmetrically arranged. The fixed rod 26 is in the shape of an inverted "U". The two ends of the fixed rod 26 pass through the top of the two fixed brackets 25 respectively. Fixed blocks 27 are fixedly connected to both ends of the fixed rod 26. The fixed blocks 27 are movably engaged inside the fixed brackets 25. The fixed blocks 27 are fixedly connected to the translation plate 3. The translation plate 3 can be moved by the fixed blocks 27, that is, the lifting mechanism 2 controls the lifting and lowering of the translation plate 3. A second hydraulic cylinder 28 is fixedly connected to the middle of one side of the lowering plate 22, and the second hydraulic cylinder 28 is located between two fixed frames 25.

The second hydraulic cylinder 28 can be used to control the vertical movement of the second hydraulic rod 29, thereby causing the fixed rod 26 and the fixed block 27 to move up and down along the inside of the fixed frame 25, thereby realizing the lifting and lowering of the fixed block 27, thus providing power for the lifting and lowering of the translation plate 3.

[0081] like Figure 6-8The rotating mechanism 4 includes a connecting plate 41, a limiting plate 42, a connecting member 43, a limiting member 44, and a rotating member 45. The connecting plate 41 is located on the side of 31 with a toothed groove. The top and bottom ends of the connecting plate 41 are fixedly connected to the limiting plate 42. The connecting member 43 consists of a connecting motor and a connecting rod, and the connecting motor is movably connected to the connecting rod. A connecting groove is provided on one side of the connecting plate 41, and the connecting plate 41 is movably engaged with the connecting rod through the connecting groove. The outer wall of the connecting rod meshes with the toothed groove of the translation plate 3. The connecting motor is fixedly installed in the upper limiting plate 42. When the connecting motor is started, it will drive the connecting rod to rotate forward or backward, causing the connecting member 43 to move along the toothed groove of the translation plate 3, thereby realizing the lateral translation of the connecting plate 41 on the translation plate 3. The top end of the connecting member 43 is movably engaged with the limiting plate 42, and the bottom end of the connecting member 43 is engaged with the translation plate 3. The limiting groove of plate 3 is movably engaged. Two connecting parts 43 are provided on a limiting plate 42, and the two connecting parts 43 are symmetrically arranged. The setting of the limiting part 44 not only makes the connecting plate 41, the limiting plate 42 and the translation plate 3 stably connected, but also reduces the resistance of the rotating mechanism 4 moving on the translation plate 3. The connecting part 43 consists of a rotating motor and a rotating rod, and the rotating motor is movably connected to the rotating rod. A rotating groove is opened on the other side of the connecting plate 41, and the connecting plate 41 is movably engaged with the rotating rod through the rotating groove. The outer wall of the rotating rod is fixedly sleeved with the loading ring 52. The rotating motor is fixedly set in the upper limiting plate 42. When the rotating motor is started, it will drive the rotating rod to rotate in the forward or reverse direction, so that the loading mechanism 5 rotates along the rotating part 45, so that the loading mechanism 5 can rotate 180 degrees, thereby realizing the offset of the loading mechanism 5 carrying the cargo component 50.

[0082] like Figure 5 , Figure 8 , Figure 12 , Figure 14-15The support assembly 9 is located at the bottom of the rotating mechanism 4 and is used to provide support force for the rotating mechanism 4. The support assembly 9 includes an air pump 91, a first support 92, a second support 93, a third support 94, a fourth support 95, a support ball 96, and an air valve 97. The interior of the air pump 91 is connected to the other end of the air pipe 62, and the top end of the air pump 91 is fixedly connected to the bottom end of the limiting plate 42. The air pump 91 can absorb air through the moving assembly 6 and discharge the air downward, thereby controlling the first support 92. The second support member 93, the third support member 94, and the fourth support member 95 undergo telescopic deformation. The top end of the first support member 92 is fixedly connected to the bottom end of the air pump member 91. The bottom end of the first support member 92 is movably sleeved with the top end of the second support member 93. The bottom end of the second support member 93 is movably sleeved with the top end of the third support member 94. The bottom end of the third support member 94 is movably sleeved with the top end of the fourth support member 95. The layered connection of the first support member 92, the second support member 93, the third support member 94, and the fourth support member 95 can achieve… The four components extend and retract. The fourth support 95 and the air pump 91 are connected by a vertical spring. The bottom end of the fourth support 95 is movably engaged with a support ball 96, allowing the support ball 96 to roll freely on the ground. When the air pressure in the space formed by the first support 92, the second support 93, the third support 94, and the fourth support 95 is low, the tension of the vertical spring causes the four components to contract and overlap. When the air pressure is high, it effectively pushes the four components downward until the support ball 96 contacts the ground, thus enabling rotation. The rotating mechanism 4 provides support. Air valves 97 are fixedly embedded inside the housings of the second support member 93, the third support member 94, and the fourth support member 95. There are several air valves 97, and they are evenly arranged around the center of the first support member 92. The air valves 97 are one-way valves. When the air pressure in the space formed by the first support member 92, the second support member 93, the third support member 94, and the fourth support member 95 is higher than a certain value, the air valves 97 are automatically opened to exhaust air to ensure the safety of the support assembly 9.

[0083] Therefore, the air pump 91 is used to fill the first support 92, the second support 93, the third support 94 and the fourth support 95 with gas, so that the support ball 96 contacts the ground. When the air pressure inside is higher than the set value, the air valve 97 releases the gas, so that the support assembly 9 is stably set between the rotating mechanism 4 and the ground, thereby achieving stable support for the rotating mechanism 4, effectively reducing the weight on one side of the translation plate 3, stabilizing the center of gravity of the translation plate 3, and preventing the three-way forklift from tilting due to the shift of the center of gravity.

[0084] The working principle of the method of using this invention is as follows:

[0085] When handling the cargo assembly 50, first insert the forks 53 to the bottom of the cargo assembly 50, placing the entire cargo assembly 50 onto the forks 53. At this point, ensure the sidewall of the cargo assembly 50 is flush with the sidewall of the moving plate 61. Then, activate the air pump 91 to extract air from the location of the moving assembly 6, specifically by using the suction holes to extract air between the moving plate 61 and the cargo assembly 50. This air is then introduced into the air pump 91 through the air pipe 62. Thus, during lifting, lowering, and translating operations, the moving plate 61 provides suction, effectively securing the cargo assembly 50, reducing its sway, improving its stability during handling, and lowering the risk of it falling. When unloading the cargo assembly 50, first control the rotating mechanism 4 to move the loading mechanism 5 forward on the translating plate 3, moving the cargo assembly 50 onto the shelf. Then, the rotating mechanism 4 moves the loading plate 51 and forks 53 backward. The rotating component 73 is activated, causing the pushing component 71 to gradually extend, thereby ensuring that the moving plate 61 remains in contact with the cargo component 50 under the control of the pushing component 7, effectively protecting the cargo component 50 and further improving the stability of the cargo component 50 during handling. When the fork 53 is about to disengage from the cargo component 50, that is, when the moving component 8 moves to the downward-sloping area of ​​the moving slot, the moving component 8 moves downward under the action of the moving spring and its own weight, thereby gradually covering the suction hole with the moving block 83, thus gradually reducing the suction effect of the moving plate 61 on the cargo component 50, preventing the sudden removal of suction from affecting the placement stability of the cargo component 50, and further improving the stability of the cargo component 50 during handling. After the cargo component 50 is completely unloaded, the moving component 6 is retracted under the control of the pushing component 7, causing the moving component 8 to move upward within the moving plate 61. Thus, the up-and-down movement of the moving component 8 effectively cleans the moving cavity of the moving plate 61, preventing dust and impurities from clogging it and extending the service life of the moving plate 61.

[0086] During the handling of the cargo assembly 50, the air pump 91 transfers air near the moving plate 61 to the space formed by the first support 92, the second support 93, the third support 94, and the fourth support 95, thereby pushing the first support 92, the second support 93, the third support 94, and the fourth support 95 to stretch until the support ball 96 contacts the ground. This provides stable support for the rotating mechanism 4, effectively reduces the weight on one side of the translation plate 3, stabilizes the center of gravity of the translation plate 3, and prevents the three-way forklift from tilting due to a shift in its center of gravity.
