Description

Technical Field

[0001] The utility model belongs to the technical field of stackers, and particularly relates to a novel stacker cargo platform and a stacker using the stacker cargo platform. Background Art

[0002] During the manufacturing process, stackers and high-bay warehouses are required for material handling and storage. The stacker platform directly carries the materials, while the stacker columns serve as the tracks on which the platform operates. For materials weighing heavier weights (e.g., over 5 tons), the stacker platform's guide wheels exert significant pressure on the stacker columns, necessitating increased strength of the stacker columns and increased diameter, number, and width of the guide wheels.

[0003] Existing stacker platforms utilize a single guide wheel. The heavier the load, the larger the guide wheel's diameter and strength, which increases the equipment's usable area (increasing the equipment's strength requirements). Using multiple guide wheels can lead to significant variations in force, or uneven force distribution across the stacker's columns due to deviations in column shape, guide wheel position, or force deformation, impacting the service life of the multiple guide wheels. Furthermore, the overall configuration of the stacker platform varies depending on the size of the material being handled. Manufacturers must customize the stacker platform for each specific requirement, resulting in long production cycles and high manufacturing costs. Summary of the Invention

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example 1

[0030] like Figure 1-8As shown, a stacker cargo platform includes a movable pulley 4, a positive guide wheel 9, a side guide wheel assembly 10, a cargo platform frame 5 and a cargo platform crossbeam 7. The cargo platform frame 5 is a standardized structural component that can be mass-produced. The cargo platform frame 5 is welded by rectangular steel pipes and steel plates. The steel plates on a cargo platform frame 5 include a frame mounting steel plate 42 and an obliquely connected reinforcing steel plate 32. There are eight rectangular steel pipes on a cargo platform frame 5. The length of the lower horizontal rectangular steel pipe 38 is greater than the length of the upper horizontal rectangular steel pipe 37. The length of the upper vertical rectangular steel pipe 40 is greater than the length of the lower vertical rectangular steel pipe 41. The top ends of a pair of upper vertical rectangular steel pipes 40 are welded to the lower surfaces of the two ends of the upper horizontal rectangular steel pipe 37, and the bottom ends of a pair of upper vertical rectangular steel pipes 40 are welded to the upper surface of the middle section of the lower horizontal rectangular steel pipe 38. The two ends of the lower horizontal rectangular steel pipe 38 are welded to the inner middle section of a pair of lower vertical rectangular steel pipes 41. The surfaces are welded into one, and the two ends of a pair of oblique rectangular steel tubes 39 are respectively welded to the outer surface of the middle section of the upper vertical rectangular steel tube 40 and the top of the lower vertical rectangular steel tube 41; the upper and lower ends of the vertical frame mounting steel plate 42 are respectively welded to the side surfaces of the upper horizontal rectangular steel tube 37 and the lower horizontal rectangular steel tube 38, and the two ends of the oblique connection reinforcement steel plate 32 are respectively welded to the side surfaces of the upper vertical rectangular steel tube 40 and the lower vertical rectangular steel tube 41; a side guide wheel assembly mounting hole 31 is respectively opened at the four corners of the vertical frame mounting steel plate 42, and a movable pulley mounting hole 8, a pair of positive guide wheel mounting holes 33 and a safety clamp mounting hole 30 are sequentially opened in the middle of the vertical frame mounting steel plate 42 from top to bottom. The pair of positive guide wheel mounting holes 33 are respectively located in the middle of the upper and lower ends of the safety clamp mounting hole 30, and a first through hole corresponding to the side guide wheel assembly mounting hole 31 is opened on the lower horizontal rectangular steel tube 38 and the upper horizontal rectangular steel tube 37. A pair of cargo platform frames 5 are arranged relatively parallel to each other, and the obliquely connected reinforcing steel plates 32 are located on the adjacent inner sides of the pair of cargo platform frames 5. The obliquely connected reinforcing steel plates 32 play a reinforcing role and ensure the cargo area and mechanical strength of the cargo platform; the frame mounting steel plates 42 are located on the outer sides opposite to each other of the pair of cargo platform frames 5, and the pair of frame mounting steel plates 42 are spaced a certain distance from the surfaces of a pair of stacker columns 13 and are arranged vertically and parallel to each other, and various parts are fixedly installed on the frame mounting steel plates 42.

[0031] The two ends of a pair of cargo platform beams 7 are respectively fixedly connected to the obliquely connected reinforcing steel plate 32 and the bottom end of the lower vertical rectangular steel tube 41 through a detachable structure. The cargo platform beam 7 is made of channel steel or other profiles, and the length of the channel steel or other profiles can be customized according to different cargo sizes; the two ends of the channel steel or other profiles are respectively welded with vertical mounting connecting plates parallel to each other, and several reinforcement plates 17 are welded at the joints between the channel steel or other profiles and the mounting connecting plates, as well as the front and rear sides of the channel steel or other profiles. The reinforcement plates 17 are used for reinforcement and support to improve the mechanical strength of the cargo platform beam 7. The mounting plates at both ends are provided with threaded holes and locating pin holes. The obliquely connected reinforcing steel plate 32 is provided with a second through-hole and a third through-hole corresponding to the threaded holes and the locating pin holes, respectively. A locating pin 18 is inserted through the third through-hole into the locating pin hole. The locating pin 18 can be installed and fixed by welding or interference fit. A bolt 19 is screwed into the threaded hole through the second through-hole. The bolts 19 and the locating pins 18 are used to fix the two standard-structure cargo platform frames 5 and the cargo platform crossbeam 7 into one body. The locating pins 18 can resist shear forces and are used in conjunction with the bolts 19 to secure the connection, thereby improving the overall mechanical support of the stacker's cargo platform and achieving a detachable structure that allows for flexible assembly of the cargo platform crossbeam 7 and the cargo platform frame 5. This allows for a variety of cargo specifications and reduces the production cycle and manufacturing cost of the overall customization of the stacker's cargo platform. A pair of fork mounting plates 20 are welded to the upper surface of the cargo platform crossbeam 7. The forks 6 are mounted on the fork mounting plates 20. The fork drive motor 12 is fixedly mounted on the lower surface of the cargo platform crossbeam 7. The fork 6 is a pallet-type double-motor double-extension double-deep fork product, which is a prior art. The fork drive motor 12 drives the fork 6 to extend and retract to accommodate cargoes of different sizes.

[0032] The cargo platform frame 5 is equipped with components such as side guide wheel assemblies 10, positive guide wheels 9, movable pulleys 4, and safety gear 14. Four sets of side guide wheel assemblies 10 are installed on the frame mounting steel plate 42 on each side. The ends of the side guide wheel assemblies 10 pass through the side guide wheel assembly mounting holes 31 and the first through-holes and are fixed to the cargo platform frame 5 using expansion sleeves 2 and bolts 19. The pair of side guide wheel assembly mounting holes 31 at the upper and lower ends are parallel and vertically symmetrical. The spacing between the pair of side guide wheel assembly mounting holes 31 at the upper and lower ends is greater than the thickness of the stacker column 13 plus the diameter of the side guide wheel 34. This ensures that when the side guide wheel assemblies 10 and the stacker column 13 are engaged, the side guide wheels 34 are evenly stressed and fit tightly together.

[0033] The side guide wheel assembly 10 includes an eccentric shaft 21, a side guide wheel bracket 23, two side guide wheel shafts 22 and two side guide wheels 34. The outer periphery of one end of the eccentric shaft 21 is sleeved with a first bearing 24. The center of the side guide wheel bracket 23 is provided with a fourth through hole. The first bearing 24 passes through the fourth through hole to sleeve the side guide wheel bracket 23 on the outer periphery of the first bearing 24. The side guide wheel bracket 23 is rotatably connected to one end of the eccentric shaft 21 through the first bearing 24. Under the action of the first bearing 24, the side guide wheel bracket 23 can By rotating around the eccentric shaft 21, the side guide wheels 34 on the side guide wheel group bracket 23 can eventually press the surface of the stacker column 13 to ensure that each side guide wheel 34 is evenly stressed. The end face of the eccentric shaft 21 on which the first bearing 24 is installed is provided with a threaded hole corresponding to the fifth through hole on the baffle 26. The baffle 26 is fixedly connected to the end of the eccentric shaft 21 by passing the bolt 19 through the fifth through hole and screwing it into the threaded hole. The diameter of the baffle 26 is larger than the diameter of the first bearing 24. The baffle 26 plays a limiting role to prevent the first bearing 24 from falling off. The upper and lower ends of the side guide wheel group bracket 23 are hollow cavity structures, and the side guide wheel shafts 22 are fixedly installed in the hollow cavity structures at the upper and lower ends of the side guide wheel group bracket 23. The cross-section of the side guide wheel shaft 22 is a T-shaped structure, one end of the side guide wheel shaft 22 is provided with a limit cap, and the other end side is provided with a groove. The end of the side guide wheel shaft 22 with the groove passes through the sixth through hole and the second bearing 25 at the upper and lower ends of the side guide wheel group bracket 23. The diameter of the limit cap is larger than the diameter of the sixth through hole. The second bearing 25 is located in the hollow cavity structure at the upper and lower ends of the side guide wheel group bracket 23, and a fixed limit plate 27 is clamped and installed in the groove at one end of the groove. The diameter of the fixed limit plate 27 is larger than the diameter of the end of the side guide wheel shaft 22 with the groove. The fixed limit plate 27 is fixedly connected to the outer surface of the side guide wheel group bracket 23 by screws, thereby preventing the side guide wheel shaft 22 from falling off and ensuring the safe operation of the device. Side guide wheels 34 are mounted on the outer periphery of the second bearing 25. The two side guide wheels 34 are rotatably connected to the upper and lower ends of the side guide wheel bracket 23 via the side guide wheel shaft 22 and the second bearing 25. Tightening the bolts 19 on the expansion sleeve 2 creates a strong clamping force, firmly connecting the eccentric shaft 21 to the cargo platform frame 5. This secures the eccentric shaft 21 and tightens the side guide wheels 34 against the stacker column 13, making the stacker's cargo platform more stable and safer. The stacker's cargo platform can also be adjusted horizontally by rotating the eccentric shaft 21.

[0034] A movable pulley 4, a positive guide wheel 9 and a safety clamp 14 are installed from top to bottom between the upper horizontal rectangular steel tube 37 and the lower horizontal rectangular steel tube 38. The top of the movable pulley support frame 3 is fixedly installed on the middle part of the lower surface of the upper horizontal rectangular steel tube 37 by bolts 19. The movable pulley fixed shaft 16 is fixedly installed on the bottom end of the movable pulley support frame 3. A hollow cavity structure is provided at the bottom end of the movable pulley support frame 3. The movable pulley 4 is rotatably mounted on the middle position of the outer periphery of the movable pulley fixed shaft 16 through a third bearing. The movable pulley 4 is located in the hollow cavity structure at the bottom end of the movable pulley support frame 3. A traction rope 1 is wrapped around the movable pulley 4. A seventh through hole is provided on the upper horizontal rectangular steel tube 37 for the traction rope 1 to pass through. After passing through the seventh through hole, the traction rope 1 is connected to the lifting and traction mechanism at the top of the stacker. The vertical lifting of the stacker cargo platform is achieved through the cooperation of the lifting and traction mechanism, the traction rope 1 and the movable pulley 4. A movable pulley mounting hole 8 is provided on the vertical frame mounting steel plate 42 , and the movable pulley mounting hole 8 can conveniently connect the movable pulley 4 and the movable pulley fixing shaft 16 .

[0035] A safety gear fixing plate 15 is bolted to the safety gear mounting hole 30, and the safety gear 14 is fixedly mounted on this safety gear fixing plate 15. Positive guide wheels 9 are rotatably mounted on the frame mounting steel plates 42 at the upper and lower ends of the safety gear fixing plate 15. Positive guide wheels 9 are rotatably mounted in the positive guide wheel mounting holes 33 via a rotating shaft and a fourth bearing. A vertical column guide rail 11 is welded to the middle of the lower half of the stacker column 13, and the positive guide wheels 9 roll in engagement with the outer surfaces of the column guide rail 11.

[0036] The positive guide wheel 9 and the side guide wheel 34 can be polyurethane wheels, and the outer periphery of the positive guide wheel 9 and the side guide wheel 34 is wrapped with a layer of polyurethane material to reduce noise. The positive guide wheel 9 and the side guide wheel 34 can also be an integrated steel wheel, which has better bearing capacity.

[0037] The stacker loading platform provided in the first embodiment of the present invention has the following advantages:

[0038] 1. By arranging multiple sets of guide wheels (including side guide wheel assemblies 10 and positive guide wheels 9) to cooperate with the stacker column 13, the positive guide wheels 9 are used to limit the left and right movement of the cargo platform, and the side guide wheel assemblies 10 are used to limit the front and rear movement of the cargo platform. By cooperating with the column guide rails 11 and the stacker column 13, the freedom of the cargo platform other than the vertical movement direction is restricted. At the same time, the multiple sets of guide wheels make the cooperation between the cargo platform and the column guide rails 11 and the stacker column 13 more stable, reduce friction and pressure at a single contact point, realize smooth lifting and lowering of the cargo platform, and thus improve the service life.

[0039] 2. Each side guide wheel assembly 10 includes two side guide wheels 34, which are supported and connected by a side guide wheel group bracket 23, and the eccentric shaft 21 is used to fix the side guide wheel group bracket 23 to the cargo platform frame 5. The side guide wheel assembly 10 and the stacker column 13 are pressed together by rotating the eccentric shaft 21, thereby reducing the pressure on a single wheel and the pressure on a single contact point of the stacker column 13. The requirements for the structural strength of the stacker column 13 are effectively reduced, so that the force is evenly distributed, the service life is increased, and the increase in the guide wheel diameter to meet the load requirements is effectively avoided, thereby reducing the equipment's occupied area.

[0040] 3. When transporting goods that are too wide, the cargo platform crossbeam 7 can be removed by bolts 19 and positioning pins 18, and replaced with a cargo platform crossbeam 7 with a length that matches the size of the goods, so as to match a variety of cargo specifications.

[0041] The first embodiment of the present invention provides a stacker loading platform, and the assembly steps are as follows:

[0042] First, select a loading platform crossbeam 7 that matches the cargo size. Use locating pins 18 and bolts 19 to securely connect the loading platform crossbeam 7 to a pair of loading platform frames 5 on either side. Position the two loading platform frames 5 against the stacker columns 13 and column guide rails 11, respectively, with the front guide wheels 9 in close contact with the column guide rails 11. Rotate the eccentric shaft 21 to adjust the level of the loading platform frames 5 and press the side guide wheels 34 against the stacker columns 13. Install the expansion sleeves 2 and tighten the bolts 19. Adjust the two loading platform frames 5 so they are perpendicular and parallel to the stacker columns 13 on either side. Finally, install the forks 6 on the loading platform crossbeam 7. The stacker columns 13 in existing stacker products feature flexible spacing adjustment.

[0043] The first embodiment of the present invention provides a stacker loading platform, and its working process is as follows:

[0044] The stacker's lifting and traction mechanism drives the traction rope 1, which is then lifted and lowered in coordination with the movable pulley 4 on the cargo platform frame 5. Multiple side guide wheels 34 and a pair of positive guide wheels 9 respectively roll in engagement with the stacker's column 13 and column guide rail 11 surfaces, causing the cargo platform to move to the loading position, where the fork 6 picks up the cargo. The stacker's lifting and traction mechanism works in coordination with the movable pulley 4 on the cargo platform frame 5 to lift and lower. Multiple side guide wheels 34 and a pair of positive guide wheels 9 respectively roll in engagement with the stacker's column 13 and column guide rail 11 surfaces, causing the cargo platform to move to the storage position, where the fork 6 deposits the cargo. If the stacker's lifting and traction mechanism is moving too fast, or if the traction rope 1 breaks or slackens, the safety clamp 14 can bring the cargo platform to an emergency stop and clamp it to the column guide rail 11. Example 2

[0045] like Figure 9 、10 As shown, a stacker includes a stacker body 29, which includes a pair of parallel stacker columns 13. The top ends of the stacker columns 13 are fixedly connected to form a single body by a connecting crossbeam, on which a lifting and traction mechanism is fixedly mounted. A column guide rail 11 is welded to the vertical center of the adjacent left and right sides of the stacker columns 13. The column guide rail 11 has a T-shaped cross-section and includes an integrally formed top beam 36 and center beam 35. The outer surface of the top beam 36 is fixedly connected to the surface of the stacker columns 13 by welding (the top beam 36 can also be fixed by bolts 19).

[0046] A stacker cargo platform body 28 is movably mounted between a pair of stacker columns 13. The stacker cargo platform body 28 utilizes the stacker cargo platform structure described in Example 1. The stacker cargo platform body 28 comprises a pair of cargo platform upright frames 5 and two cargo platform crossbeams 7 fixedly connected to the cargo platform upright frames 5 via a detachable structure. The width of the crossbeams 7 matches the spacing between the pair of stacker columns 13. A pair of positive guide wheels 9 of the stacker cargo platform body 28 abut against the outer side surfaces of the ends of the center beam 35 of the column guide rails 11. The side surfaces of the center beam 35 engage with the safety clamps 14 of the stacker cargo platform body 28. In abnormal situations, the safety clamps 14 can bring the cargo platform to an emergency stop and clamp it to the side surfaces of the center beam 35 (prior art). The four sets of side guide wheel assemblies 10 of the stacker platform body 28 cooperate with the front and rear side surfaces of the stacker column 13. The side guide wheels 34 in the side guide wheel assemblies 10 are in close contact with the front and rear side surfaces of the stacker column 13. Through the pair of positive guide wheels 9 and the four sets of side guide wheel assemblies 10, and in conjunction with the column guide rails 11 and the stacker column 13, the stacker platform body 28 can be smoothly raised and lowered vertically relative to the stacker body 29. The lifting and lowering of the stacker platform body 28 allows for the forking and storage of goods.
