Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of roadway stackers, and particularly relates to a multi-roadway heavy-duty high-precision stacker for logistics. Background Art
[0002] Roadway stackers play an important role in the field of automated warehousing and can quickly store and retrieve logistics goods. However, most current roadway stackers still have the following key problems, which restrict their application in handling heavy goods. Because when traditional stackers handle goods, one end of the forklift fork that extends is mostly in a suspended state. After long-term use, the forklift fork is prone to deformation, affecting the handling work. Moreover, although the existing stackers have improved speed control through variable frequency speed regulation, thereby reducing the risk of damage to goods caused by vibration, they are still subject to impact when braking and holding. To solve the above problems, the present invention provides a multi-roadway heavy-duty high-precision stacker for logistics. Summary of the Invention
[0003] Aiming at the above existing technical deficiencies, the purpose of the present invention is to provide a multi-roadway heavy-duty high-precision stacker for logistics. When lifting goods, the sliding rod is lapped on the shelf to achieve two-end support, thus stably playing a supporting role. Moreover, when the lifting plate drives the goods to move, it can buffer the goods, reducing damage to the goods caused by impact due to vibration or sudden stop.
[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a multi-roadway heavy-duty high-precision stacker for logistics, including:
[0005] An overhead rail, which is slidably connected to a slide rail installed on the top wall of the warehouse;
[0006] A ground rail, which is slidably connected to a slide rail installed on the ground of the warehouse;
[0007] A base frame, which is fixedly installed between the overhead rail and the ground rail;
[0008] A lifting plate, which is installed inside the base frame and slides along the height direction of the base frame;
[0009] Multiple handling components, which are installed on the lifting plate and slide along the short side direction of the lifting plate, and can extend from both sides of the lifting plate to the logistics storage rack;
[0010] Among them, when the handling component is handling, the extended end is lapped on the logistics storage rack.
[0011] Preferably, the handling component includes:
[0012] A sliding rod, which is slidably installed in a chute provided on the lifting plate;
[0013] A support plate, which is slidably installed in an empty groove provided inside a sliding rod and is used to lift goods;
[0014] Wherein, the sliding rod is movably clamped with a driving part installed on the lifting plate.
[0015] Preferably, the driving part includes:
[0016] A handling screw rod, which is rotatably installed in a groove provided on the lifting plate, and the handling screw rod is driven by a handling motor installed on the lifting plate;
[0017] Two sliders, which are slidably installed in the groove and are movably clamped with the sliding rod. The two sliders are respectively located at both ends of the groove. A through hole is provided on the slider, and the diameter of the through hole is larger than the diameter of the handling screw rod. A screw sleeve is rotatably clamped inside the through hole;
[0018] Wherein, when the screw sleeve is clamped with the slider, the handling screw rod rotates to drive the slider to slide in the groove. When the screw sleeve is disengaged from the slider, the handling screw rod rotates to drive the screw sleeve to rotate synchronously.
[0019] Preferably, a clamping rod is slidably installed at the upper end of the slider, and a clamping groove adapted to the clamping rod is provided on the sliding rod.
[0020] Preferably, a cavity is provided inside the slider, and the clamping rod penetrates through the slider and extends into the cavity and is fixedly connected with a piston plate;
[0021] A plurality of clamping blocks are slidably installed on the inner side wall above the axis of the through hole. A plurality of slots adapted to the clamping blocks are circumferentially distributed on the screw sleeve. The clamping blocks penetrate through the slider and extend into the cavity and are fixedly connected with an elastic plate fixedly connected to the inner side wall of the cavity;
[0022] Wherein, a handling push rod is installed inside the cavity, a pressing plate is fixedly installed on the output rod of the handling push rod, and hydraulic oil is filled inside the cavity above the pressing plate.
[0023] Preferably, a buffer part is provided inside the empty groove and below the support plate. When lifting goods, the buffer part is used to lift the support plate. When the goods are transported to the lifting plate, the buffer part can play a buffering role for the goods during the movement process.
[0024] Preferably, the buffer part includes:
[0025] A fixing plate, which is fixedly installed inside the empty groove;
[0026] A floating plate, which is located above the fixing plate and is slidably installed inside the sliding groove. An elastic ring is installed between the periphery of the floating plate and the fixing plate.
[0027] Preferably, a cavity is provided below the fixed plate. A plurality of partition plates are fixedly installed inside the cavity. Lifting push rods are provided on both sides of each partition plate. A lifting piston is fixedly installed on the output rod of the lifting push rod. Oil discharge ports are provided on both sides of the partition plate and on the fixed plate.
[0028] Preferably, a buffer frame is fixedly connected between the fixed plate and the floating plate above the partition plate. The buffer frame is made of an elastic material, and its cross-section is a concave arc.
[0029] Preferably, the sliding rod is in the shape of an inverted "U", the two ends of its open end are folded in the direction away from each other, and a plurality of rolling balls are rotatably installed on the folded ends, and the rolling balls respectively penetrate through the upper and lower side walls of the folded ends.
[0030] The beneficial effects of the present invention are as follows:
[0031] The driving part of the present invention adopts the linkage control of the handling screw and the slider, and combines with the clamping mechanism of the screw sleeve, so that the sliding rod can slide out from both sides of the lifting plate as needed to carry the goods on the shelves on both sides of the roadway. When carrying, the supporting plate rises to lift the goods. At this time, one end of the sliding rod is lapped on the shelf and the other end is on the lifting plate, which can stably play a supporting role, so as to realize the stable lifting and carrying of the goods.
[0032] Through the settings of the fixed plate, the floating plate and the buffer frame in the present invention, when the output rod of the lifting push rod extends, the hydraulic oil enters the inside of the buffer frame through the oil discharge port, and then pushes the floating plate to drive the supporting plate to rise to lift the goods. When the goods move above the lifting plate, the output rod of the lifting push rod retracts, and the hydraulic oil flows back to the lower part of the fixed plate through the oil discharge port. In this process, the combined design of the buffer frame, the elastic ring and the hydraulic oil can effectively absorb the impact force during the goods handling process. At the same time, by controlling the extension length of the output rod of the lifting push rod, the buffer strength can be dynamically adjusted to reduce the risk of damage to the goods caused by vibration or sudden stop.

Detailed implementation manners
[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0048] The present invention provides a multi-aisle heavy-duty high-precision stacker for logistics, as Figures 1 to 11 shown.
[0049] Embodiment 1:
[0050] A multi-aisle heavy-duty high-precision stacker for logistics includes a sky rail 1 and a ground rail 2. The sky rail 1 is slidably connected to a slide rail installed on the top wall of the warehouse, and the ground rail 2 is slidably connected to a slide rail installed on the ground of the warehouse. A base frame 3 is fixedly installed between the sky rail 1 and the ground rail 2. A stable frame is formed among the sky rail 1, the ground rail 2, and the base frame 3, serving as the main support structure of the stacker.
[0051] An elevator plate 4 is installed inside the base frame 3. The elevator plate 4 slides along the height direction of the base frame 3. Both ends of the elevator plate 4 extend into the slide rails provided on the inner side walls of the base frame 3 and are threadedly connected to elevator screws 33 rotatably provided inside the slide rails. The elevator screws 33 are driven by an elevator motor 34 installed inside the base frame 3. The rotation of the motor shaft of the elevator motor 34 can drive the elevator screws 33 to rotate, thereby driving the elevator plate 4 to slide inside the base frame 3. By controlling the rotation direction of the motor shaft of the elevator motor 34, the elevator plate 4 can be controlled to rise and fall.
[0052] A plurality of handling components are installed on the elevator plate 4. The handling components can extend from both sides of the elevator plate 4 according to the handling needs to handle the goods located on both sides of the aisle. After the handling components extend out, the end located outside the elevator plate 4 will be inserted under the logistics pallet and lapped on the logistics storage rack. Then, the handling components will lift the goods and drive the goods to move towards the elevator plate. At this time, the logistics storage rack can support the handling components located above it, enabling the handling components to stably handle heavy goods.
[0053] The handling component includes a slide bar 5. The slide bar 5 is slidably installed on the elevator plate 4 through a chute 6 provided on the elevator plate 4. A driving part is installed inside the chute 6. The driving part controls the slide bar 5 to move along the track of the chute 6. A support plate 7 is installed on the upper side of the slide bar 5. The support plate 7 is used to lift the goods. During handling, the slide bar 5 extends out from the corresponding side of the elevator plate 4 according to the position of the goods and is inserted under the logistics pallet. At the same time, the end of the slide bar 5 located outside the elevator plate 4 will be lapped on the logistics storage rack, forming a two-end support structure to avoid deformation caused by suspension.
[0054] Meanwhile, the shape of the sliding rod 5 is set as an inverted "U" shape, which can play a more stable supporting role. The two ends of the opening end of the sliding rod 5 are folded in the direction away from each other. A plurality of rolling balls 31 are rotatably installed at the folding position, and the rolling balls 31 respectively penetrate through the upper and lower side walls of the folding end and extend to the outside of the folding end. The setting of the rolling balls 31 can reduce the friction between the sliding rod 5 and the groove wall of the sliding groove 6 and between the sliding rod 5 and the logistics shelf, so that the sliding rod 5 moves stably when carrying goods, enhancing the smoothness during the handling process.
[0055] Embodiment Two:
[0056] On the basis of Embodiment One, the driving part includes: a handling screw rod 8, which is rotatably installed inside the groove 9. The groove 9 is arranged on the lifting plate 4, and one end of the handling screw rod 8 is fixedly connected with a sprocket. The sprocket is connected to the motor shaft of the handling motor 11 through a chain. A sprocket is also fixedly connected to the motor shaft of the handling motor 11. The handling motor 11 is installed on the lifting plate 4, and the rotation of the motor shaft of the handling motor 11 can drive the handling screw rod 8 to rotate inside the groove 9.
[0057] Two sliders 10 are slidably installed inside the groove 9. The two sliders 10 are respectively located at both ends of the groove 9. The sliders 10 are provided with through holes 12 adapted to the handling screw rod 8. The axis of the through hole 12 coincides with the axis of the handling screw rod 8, and a screw sleeve 13 is rotatably installed inside the through hole 12. The screw sleeve 13 is threadedly connected with the handling screw rod 8. The sliders 10 are movably clamped with the sliding rod 5 and the screw sleeve 13. When the sliders 10 are clamped with the sliding rod 5 and the screw sleeve 13, the rotation of the handling screw rod 8 can drive the sliding rod 5 to slide on the lifting plate 4 through the screw sleeve 13. When the sliders 10 are disengaged from the clamping with the sliding rod 5 and the screw sleeve 13, the rotation of the handling screw rod 8 will drive the screw sleeve 13 to rotate idly.
[0058] As Figure 5 shown, when it is necessary to make the sliding rod 5 extend to the left, the slider 10 located at the right end inside the corresponding groove 9 is clamped with the sliding rod 5 and the screw sleeve 13, and the slider 10 located at the left end of the corresponding groove 9 is disengaged from the clamping with the sliding rod 5 and the screw sleeve 13, so that the sliding rod 5 can extend a longer length from the left side, and then can stably carry goods.
[0059] A clamping rod 14 is slidably installed at the upper end of the slider 10. The sliding rod 5 is provided with a clamping groove 15 adapted to the clamping rod 14. A plurality of clamping blocks 32 are slidably installed on the inner side wall above the axis of the through hole 12. A plurality of slots 19 adapted to the clamping blocks 32 are circumferentially distributed on the screw sleeve 13. The clamping rod 14 and the clamping blocks 32 both penetrate through the slider 10 and extend into the cavity 16 provided inside the slider 10;
[0060] One end of the clamping rod 14 located inside the cavity 16 is fixedly connected with a piston plate 17. One end of the clamping block 32 located inside the cavity 16 is fixedly connected with an elastic plate 18. The periphery of the elastic plate 18 is fixedly connected with the inner side wall of the cavity 16. On both sides inside the cavity 16, a handling push rod 20 is installed. A pressing plate 21 is fixedly connected to the output rod of the handling push rod 20. Hydraulic oil is contained in the cavity 16 above the pressing plate 21.
[0061] The output rod of the handling push rod 20 extends out, and can push the hydraulic oil through the pressing plate 21, so that the hydraulic oil pushes the piston plate 17 to drive the clamping rod 14 to slide upward, and is clamped with the slot 15 on the sliding rod 5, so that the slider 10 is clamped with the sliding rod 5. At the same time, the hydraulic oil will push the clamping block 32, so that the clamping block 32 overcomes the elastic force of the elastic plate 18 and is mutually clamped with the slot 19 on the screw sleeve 13, so that the slider 10 is mutually clamped with the screw sleeve 13. At this time, when the handling screw rod 8 rotates, it will drive the corresponding sliding rod 5 to slide through the slider 10.
[0062] When the output rod of the handling push rod 20 retracts, at this time the pressing plate 21 slides downward to make room. At this time, the clamping rod 14 slides downward under the action of its own gravity and disengages from the slot 15. The clamping block 32 slides toward the inside of the cavity 16 under the elastic force of the elastic plate 18 and disengages from the slot 19. At this time, the slider 10 disengages from the sliding rod 5 and the screw sleeve 13.
[0063] By controlling the telescoping of the output rod of the handling push rod 20, it can be realized whether the handling screw rod 8 can drive the sliding rod 5 to slide through the slider 10.
[0064] Embodiment 3:
[0065] On the basis of Embodiment 1, in order to control the lifting of the supporting plate 7, the supporting plate 7 is slidably installed in the empty slot 35 provided on the upper side of the sliding rod 5, and a buffer is installed inside the empty slot 35 below the supporting plate 7. When lifting the goods, the buffer is used to lift the supporting plate 7. When the goods are carried to the lifting plate 4, the buffer can play a buffering role for the goods during the movement process.
[0066] The buffer includes a fixed plate 22 and a floating plate 23. The fixed plate 22 is fixedly connected inside the empty slot 35. The floating plate 23 is located above the fixed plate 22 and slides inside the empty slot 35. The floating plate 23 and the fixed plate 22 are connected by an elastic ring 24.
[0067] Below the fixed plate 22 is provided with an inner cavity 28. Inside the inner cavity 28, a plurality of partition plates 25 are fixedly installed. On both sides of each partition plate 25, there are lifting push rods 26. On the output rod of the lifting push rod 26, a lifting piston 27 is fixedly installed. On both sides of each partition plate 25 and on the fixed plate 22, there are oil discharge ports 29. There is hydraulic oil between the lifting piston 27 and the corresponding partition plate 25. Above the partition plate 25 and between the fixed plate 22 and the floating plate 23, a buffer frame 30 is fixedly connected. The material of the buffer frame 30 is an elastic material, and the upper and lower sides of the buffer frame 30 are respectively fixedly connected to the fixed plate 22 and the floating plate 23. The cross-section of the buffer frame 30 is a concave arc. When the output rod of the lifting push rod 26 extends out, it will push the hydraulic oil through the lifting piston 27, and the hydraulic oil enters the buffer frame 30 through the oil discharge port 29, so that the floating plate 23 rises and drives the support plate 7 to lift the goods.
[0068] Since the material of the buffer frame 30 is an elastic material, when subjected to an impact force, the buffer frame 30 and the elastic ring 24 can produce elastic deformation to absorb the impact force and reduce the risk of damage to the goods caused by vibration.
[0069] By controlling the extension length of the output rod of the lifting push rod 26, the amount of oil entering the buffer frame 30 (i.e., increasing the oil pressure) can be adjusted, and the support stiffness of the floating plate 23 can be changed. For example, when lifting the goods, the amount of oil entering the buffer frame 30 can be increased to strengthen the support. When the goods are transported to the lifting plate 4, the amount of oil entering the buffer frame 30 can be reduced (i.e., reducing the oil pressure) to enhance the flexibility of the buffer and protect the goods.
