Description

Technical Field

[0001] This invention relates to the field of stacker crane technology, and in particular to an ultra-high double-column stacker crane. Background Technology

[0002] Stacker cranes, also known as stacker machines, are the most important lifting and transportation equipment in automated warehouses and are a symbol representing the characteristics of automated warehouses. The main function of stacker cranes is to move back and forth in the aisles of the automated warehouse, storing goods located at the aisle entrance into the racking compartments, or retrieving goods from the racking compartments and transporting them to the aisle entrance.

[0003] Traditional stacker cranes typically use a loading platform and telescopic forks on the platform to pick up goods from shelves, usually picking up only one set of goods at a time. Some stacker cranes increase the lateral dimensions of the frame to increase the load capacity, but this also increases the horizontal volume of the stacker crane, which restricts its movement in some confined spaces. In conclusion, there is still room for improvement in the traditional stacker crane in terms of increasing load capacity.

[0004] Therefore, it is necessary to provide an ultra-high double-column stacker crane to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an ultra-high double-column stacker crane to solve the problem mentioned in the background art that existing stacker cranes generally use a loading platform and telescopic forks on the loading platform to pick up goods on the rack. At most, only one set of goods is picked up at a time. Some stacker cranes increase the lateral dimension of the frame to increase the loading capacity of the stacker crane, but at the same time, they also increase the volume of the stacker crane in the horizontal direction, which restricts the movement of the stacker crane in some narrow spaces.

[0006] Based on the above ideas, the present invention provides the following technical solution: an ultra-high double-column stacker crane, comprising:

[0007] The loading platform is slidably mounted on the frame;

[0008] Telescopic forks are fixedly installed on both sides of the top of the loading platform for picking up and removing goods;

[0009] A support plate is located at the top of the loading platform and outside the telescopic forks, and the height of the support plate is lower than the height of the telescopic forks.

[0010] A bottom plate is arranged at a position below the loading platform and is in sliding fit with the frame, and the bottom plate is connected with the support plate through a scissor type telescopic structure, when the bottom plate is locked with the frame and the scissor type telescopic structure is kept stable relative to the support plate, the goods can be supported through the support plate, so that the loading platform and the support plate form a storage space for accommodating another group of goods during the downward movement of the loading platform relative to the support plate.

[0013] As a further scheme of the present application, the bottom of the loading platform is fixedly provided with a protrusion at both sides, and a slot corresponding to the protrusion is formed in the bottom plate, when the protrusion is inserted into the slot and locked with the bottom plate through the limiting assembly at the side of the bottom plate, the bottom plate can move synchronously with the loading platform.

[0014] As a further scheme of the present application, the limiting assembly comprises a shell and a sliding plate elastically connected in the shell, a driving unit is fixedly installed in the shell and is in cooperation with the sliding plate for driving the sliding plate to move relative to the shell, a plug rod is fixedly installed at one side of the sliding plate, the vertical part of the frame is a column, and a plug hole corresponding to the plug rod is formed in the inner wall of the column, the side surface of the protrusion and the side surface of the upper base.

[0015] As a further scheme of the present application, side plates are fixedly installed at both sides of the loading platform, a guide block is fixedly arranged at the side of the support plate close to the side plate, and a guide groove in sliding fit with the guide block is formed in the inner side surface of the side plate.

[0016] As a further scheme of the present application, slide grooves are formed at both sides of the top of the support plate, the upper base is slidably assembled in the slide grooves after passing through the loading platform, and a stop portion is formed between the two slide grooves, when the scissor type telescopic structure is unfolded to the limit position, the upper base is in contact with the end surface of the stop portion.

[0017] As a further scheme of the present application, a sliding block is fixedly installed at the side of the side plate close to the column, and the sliding block is slidably assembled in the column.

[0018] As a further scheme of the present application, the end of the insertion rod away from the sliding plate passes through the preset circular hole of the shell and is in sliding fit with the shell.

[0019] As a further scheme of the present application, a through slot is formed in the loading platform for the shearing telescopic structure to pass through, so that the loading platform can move up and down relative to the shearing telescopic structure.

[0031] like Figures 1-8 As shown, an ultra-high double-column stacker crane includes a frame 1 that slides between a top rail and a ground rail. A loading platform 2 is slidably mounted on the frame 1. A lifting assembly fixed to the frame 1 can drive the loading platform 2 to move up and down relative to the frame 1. A telescopic fork 9 is installed on the loading platform 2. In actual use, the lifting assembly moves the loading platform 2 to a designated position, and the telescopic fork 9 is used to pick up the pallet and the goods on the pallet, which is conducive to transporting the goods to the loading platform 2. The specific structure of the frame 1 moving on the rail and the structure of the telescopic fork 9 are mature technologies and will not be described in detail here.

[0032] Combination Figures 1-5 As shown, in order to improve the efficiency of cargo handling, support plates 8 are provided on both sides of the top of the loading platform 2, and bottom plates 3 are provided on both sides of the bottom of the loading platform 2 to cooperate with the support plates 8. The support plates 8 and bottom plates 3 on the same side are connected by a scissor telescopic structure 4, and a through slot 15 is provided on the loading platform 2 for the scissor telescopic structure 4 to pass through, so that the loading platform 2 can move up and down relative to the scissor telescopic structure 4. Initially, the support plates 8 rest on the loading platform 2 and their height is less than the height of the telescopic forks 9, so that the telescopic forks 9 do not contact the support plates 8 when they pick up the cargo onto the loading platform 2.

[0033] In actual use, the base plate 3 has two states. First, the base plate 3 is not locked to the frame 1, allowing the base plate 3 to slide relative to the frame 1. At this time, the scissor telescopic structure 4 between the base plate 3 and the support plate 8 can retract. When the loading platform 2 moves down to the bottom position of the frame 1, the scissor telescopic structure 4 is in a folded state, so that the loading platform 2 can be in a lower position and the goods can be sent out of the loading platform 2 by the telescopic fork 9.

[0034] Secondly, the bottom plate 3 is locked with the frame 1 and the scissors type telescopic structure 4 keeps the unfolded state, when the loading platform 2 moves downwards, the goods on the top of the telescopic forks 9 are retained on the support plate 8, and the loading platform 2 moves downwards relative to the scissors type telescopic structure 4, so that the storage space for containing another group of goods is formed between the loading platform 2 and the support plate 8, through the structure, two groups of goods can be stacked on the loading platform 2, so as to improve the efficiency of goods transportation, and the volume of the frame 1 is not increased in the horizontal direction.

[0035] The upper base 13 is hinged on both ends of the scissors type telescopic structure 4 near the support plate 8, and the upper base 13 is in sliding fit with the support plate 8, and the lower base 14 is hinged on both ends of the scissors type telescopic structure 4 on the bottom plate 3, and the lower base 14 is in sliding fit with the bottom plate 3.

[0036] Combining Figures 2-6 As shown, the limiting assembly 10 is fixedly arranged on the bottom of the bottom plate 3, on the side of the bottom plate 3 away from the frame 1, and on the side of the support plate 8 away from the frame 1, in actual use, the limiting assembly 10 on the bottom of the bottom plate 3 can lock the bottom plate 3 on the frame 1 in cooperation with the frame 1, and the limiting assembly 10 on the side of the support plate 8 can lock the upper base 13 and the support plate 8, so as to make the scissors type telescopic structure 4 keep the unfolded state, so that the support plate 8 can stably support the goods.

[0037] Further, the lug 12 is fixedly arranged on both sides of the bottom of the loading platform 2, and the slot 301 corresponding to the lug 12 is arranged on the bottom plate 3, when the bottom plate 3 is locked with the frame 1 and the loading platform 2 moves downwards relative to the scissors type telescopic structure 4, the lug 12 can be inserted into the slot 301, and the lug 12 can be locked with the bottom plate 3 through the limiting assembly 10 on the side of the bottom plate 3, so that the bottom plate 3 can move synchronously with the loading platform 2, and then drive the stacked two groups of goods to move in the vertical direction along the frame 1.

[0038] Working principle: when the bottom plate 3 is not locked with the frame 1 and the upper base 13 is not locked with the support plate 8, the scissors type telescopic structure 4 is in the unfolded state and can freely expand and contract, therefore, when the telescopic forks 9 pick up the goods to the loading platform 2 and the lifting assembly lowers the loading platform 2 to the bottom of the frame 1, the scissors type telescopic structure 4 can be folded under pressure, so as to facilitate the loading platform 2 to reach the corresponding unloading position;

[0039] When multiple groups of goods need to be taken out, the bottom plate 3 is locked with the rack 1 through the limiting assembly 10 below the bottom plate 3, so that the bottom plate 3 is prevented from moving up and down relative to the rack 1, and at the same time, the upper base 13 is locked with the support plate 8 through the limiting assembly 10 on one side of the support plate 8, so that the scissor-type telescopic structure 4 is prevented from shrinking, and then, when the lifting assembly drives the loading table 2 to move downward, the goods on the loading table 2 can fall on the support plate 8, so that the goods can be supported through the cooperation of the support plate 8, the bottom plate 3 and the scissor-type telescopic structure 4, and when the loading table 2 moves downward to the bottom plate 3, the protrusion 12 can be inserted into the slot 301, and the protrusion 12 is locked with the bottom plate 3 through the limiting assembly 10 on one side of the bottom plate 3, so that a storage space for accommodating another group of goods is formed between the loading table 2 and the support plate 8, so that the telescopic fork 9 can pick up another group of goods to the loading table 2;

[0040] After picking up two groups of goods, the limiting assembly 10 below the bottom plate 3 can be disengaged from the rack 1, so that the bottom plate 3 is assembled on the loading table 2 and moves up and down with the loading table 2, and specifically, when the lifting assembly drives the loading table 2 to descend to the unloading position, the goods on the top of the telescopic fork 9 are sent out, and then the lifting assembly drives the loading table 2 to move upward and lifts the goods on the top of the support plate 8, at this time, the limiting assembly 10 on one side of the support plate 8 is disengaged from the upper base 13, so that the loading table 2 can drive the goods to descend during the process, so as to facilitate the folding and shrinking of the scissor-type telescopic structure 4, thereby avoiding the interference between the scissor-type telescopic structure 4 and the goods, and thus the two groups of goods stacked above the loading table 2 are unloaded.

[0041] In summary, the device can place the picked goods through the loading table 2, and when the loading table 2 moves downward relative to the support plate 8, the goods that have been picked up can be supported through the support plate 8, and the storage space for accommodating another group of goods is formed between the loading table 2 and the support plate 8, thereby facilitating the storage and transportation of two groups of goods, which can significantly improve the operation efficiency of the stacking machine, and does not increase the width of the rack 1, so that the rack 1 can remain flexible.

[0042] In combination Figures 2-8 As shown in the drawings, the limiting assembly 10 comprises a housing 1003 and a sliding plate 1002 elastically connected in the housing 1003, and specifically, a tension spring is connected between the sliding plate 1002 and the end face of the housing 1003, and a driving unit 1004 is fixedly installed in the housing 1003, and the driving unit 1004 cooperates with the sliding plate 1002 to drive the sliding plate 1002 to move relative to the housing 1003, and specifically, the housing 1003 is fixedly connected with the bottom plate 3 and the support plate 8;

[0043] A rod 1001 is fixedly installed on one side of the slide plate 1002. The end of the rod 1001 away from the slide plate 1002 passes through a pre-set circular hole on the housing 1003 and slides in cooperation with the housing 1003. Figures 2-4 , Figure 7 As shown, the vertical part of the frame 1 is a column 101, and the cross-section of the column 101 is a U-shaped structure. The inner wall of the column 101, the side of the protrusion 12, and the side of the upper base 13 are all provided with insertion holes 11 that cooperate with the insertion rod 1001. In actual use, one end of the housing 1003 located below the base plate 3 extends into the column 101 to keep the base plate 3 stable, so that the base plate 3 can only move up and down relative to the column 101. When the drive unit 1004 below the base plate 3 drives the slide plate 1002 to move outward so that the insertion rod 1001 cooperates with the insertion hole 11 on the column 101, the base plate 3 is locked to the frame 1.

[0044] Combination Figure 3 As shown, the support plate 8 has sliding grooves on both sides of its top. The upper base 13 passes through the through groove 15 on the loading platform 2 and is slidably assembled in the sliding groove. A stop 801 is formed between the two sliding grooves. When the scissor telescopic structure 4 is extended to its limit position, the upper base 13 contacts the end face of the stop 801. At this time, the insertion rod 1001 on one side of the support plate 8 can be aligned with the insertion hole 11 on the upper base 13. Specifically, when the sliding plate 1002 is moved outward by the drive unit 1004 on one side of the support plate 8, one end of the insertion rod 1001 can pass through the preset through hole on the support plate 8 and cooperate with the insertion hole 11 on the side of the upper base 13 to lock the upper base 13 and the support plate 8, thereby helping to maintain the stability of the scissor telescopic structure 4.

[0045] Furthermore, after the protrusion 12 passes through the slot 301 on the base plate 3, the sliding plate 1002 can be driven outward by the drive unit 1004 on one side of the base plate 3, so that the insertion rod 1001 on one side of the base plate 3 cooperates with the insertion hole 11 on the side of the protrusion 12, thereby locking the protrusion 12 and the base plate 3.

[0046] Side plates 5 are fixedly installed on both sides of the loading platform 2. A slider 6 is fixedly installed on the side of the side plate 5 near the column 101. The slider 6 is slidably assembled inside the column 101. A winch is installed on both sides of the frame 1. The wire rope on the winch passes over the pulley at the top of the frame 1 and extends downwards and is fixedly connected to the slider 6, thereby driving the loading platform 2 to move up and down.

[0047] The support plate 8 is fixedly provided with a guide block 7 near one side of the side plate 5, and a guide groove 501 matched with the guide block 7 is formed in the inner side of the side plate 5; when the loading platform 2 moves downward relative to the scissor type telescopic structure 4, the guide block 7 can always slide along the guide groove 501, so as to keep the transverse stability of the support plate 8, and the goods can be stably placed on the top of the support plate 8.

[0048] The rear cross rod is fixedly installed in the sliding groove, and the cross rod penetrates through the upper base 13 and is in sliding fit with the upper base 13.

[0049] The scissor type telescopic structure 4 mainly comprises a plurality of groups of cross-linked connecting rods (scissor arms), and the upper base 13 and the lower base 14 are hingedly connected with the connecting rods. Figure 5 As shown in the figure, the top of the bottom plate 3 is provided with a strip-shaped groove in sliding fit with the lower base 14, and the strip-shaped groove and the lower base 14 are both in T-shaped structure, so that the lower base 14 can stably slide in the strip-shaped groove without being separated from the bottom plate 3. Of course, a stopper can also be arranged at the middle position of the strip-shaped groove to position the lower base 14.

[0050] As the first embodiment of the driving unit 1004, the driving unit 1004 can be an electromagnet, and the sliding plate 1002 is made of magnetic material. When the magnetic property of the opposite side of the electromagnet and the sliding plate 1002 is opposite, the sliding plate 1002 can be attracted outward, so as to make the plug rod 1001 cooperate with the insertion hole 11. When the magnetic property of the opposite side of the electromagnet and the sliding plate 1002 is the same, the sliding plate 1002 can drive the plug rod 1001 to separate from the insertion hole 11. As the second embodiment of the driving unit 1004, the driving unit 1004 can also be an electric push rod. The output end of the electric push rod is connected with the sliding plate 1002, so as to drive the sliding plate 1002 to move in the shell 1003. In actual operation, the driving unit 1004 can be controlled by the staff or programmed controlled by a controller (such as PLC or single-chip microcomputer).

[0051] The above disclosure is only the preferred embodiment of the present application, which is convenient for the technical personnel in the field to understand and implement, but it cannot limit the scope of the present application. Therefore, the equivalent changes made according to the scope disclosed in the present application still belong to the scope covered by the present application.
