[0072] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0073] This embodiment provides a gantry and a handling device capable of forking or transferring multiple pallets at one time.

[0074] Figure 1 It is a schematic diagram of the main structure of the handling equipment in this embodiment.

[0075] See also Figure 1 The embodiment of the utility model provides a transport device 100, which includes a gantry 100a and two attachments 100b. The gantry 100a is used to carry and drive the attachments 100b.

[0076] Figure 2 Schematic diagram of the three-dimensional structure of the door frame in this embodiment; Figure 3 It is a schematic diagram of the three-dimensional structure of the inner and outer door frames in this embodiment.

[0077] Combination Figure 2As shown, the door frame 100a includes an outer door frame 10 and two inner door frames 20. The outer door frame 10 has a height direction, and the inner door frame installation spaces 101 are respectively arranged on both sides of the first direction perpendicular to the height direction. The two inner door frames 20 are movably installed in the two inner door frame installation spaces 101, respectively, and can be moved in the height direction respectively. Each inner door frame 20 is configured to carry the attachment 100b. Among them, the outer door frame 10 includes two first enclosures 11 and a first connecting portion 12. The two first enclosures 11 are arranged at intervals along a second direction perpendicular to the height direction, and the second direction is perpendicular to the first direction. The first connecting portion 12 is arranged between the two first enclosures 11, and the opposite two ends are respectively fixed to the two first enclosures 11. The first enclosure 11 extends along the first direction, and the two extension ends protrude a distance relative to the two ends of the first connecting portion 12 in the first direction. The area between the two first enclosures 11 and located on one side of the first connecting portion 12 constitutes an inner door frame installation space 101. The two opposite ends of the inner door frame 20 are respectively slidably connected to the inner walls of the two first enclosure parts 11 .

[0078] It should be noted that Figure 2 The direction indicated by A is the height direction. Figure 3 The direction indicated by B is the first direction. Figure 3 The direction indicated by C is the second direction.

[0079] It can be understood that the inner mast 20 is installed in the inner mast installation space 101. When the inner mast 20 moves in the height direction in the inner mast installation space 101, it can lead the accessories 100b thereon to move synchronously, thereby driving the accessories 100b to fork or transfer pallets. Through the arrangement of the two first enclosure parts 11 and the first connecting part 12, two inner mast installation spaces 101 can be formed in the area between the two first enclosure parts 11 and on both sides of the first connecting part 12, so that the two inner masts 20 can be installed in one inner mast installation space 101 respectively, so that the mast 100a can be installed with two sets of accessories 100b, and two pallets can be forked or transferred at a time, and the efficiency is effectively improved.

[0080] In this embodiment, the two first enclosure parts 11 are parallel to each other, the first connecting part 12 is parallel to the two first enclosure parts 11, and the inner door frame installation space 101 is a rectangular space.

[0081] Figure 4 It is a schematic diagram of the three-dimensional structure of the inner door frame in this embodiment.

[0082] Combination Figure 3 to Figure 4As shown, the door frame 100a also includes two groups of first position limiting guide mechanisms 30, and each first position limiting guide mechanism 30 corresponds to an inner door frame 20. Each first position limiting guide mechanism 30 includes a first guide rail 31 and a plurality of first rolling units 32. The first guide rail 31 is fixed to one end of the first connecting portion 12 in the first direction and extends in the height direction. A plurality of first rolling units 32 are arranged on one end of the inner door frame 20 facing the first connecting portion 12 and are spaced apart in the height direction. Each first rolling unit 32 includes a first roller mounting seat 321 and two first rollers 322. The first roller mounting seat 321 is fixed to the inner door frame 20. The two first rollers 322 are rotatably arranged on the first roller mounting seat 321 and are spaced apart in the second direction. The circumferential surfaces of the two first rollers 322 are respectively in contact with two opposite surfaces on the first guide rail 31.

[0083] It can be understood that when the inner door frame 20 moves along the height direction, it can drive the multiple first rolling units 32 thereon to move synchronously, so that the two first rollers 322 in each first rolling unit 32 move along the first guide rail 31, thereby ensuring the stability of the inner door frame 20 when moving along the height direction and effectively avoiding shaking.

[0084] Combination Figure 3 As shown, the first connection portion 12 includes a plurality of first connection plates 121 and at least one first reinforcement plate 122. The plurality of first connection plates 121 are arranged at intervals along the height direction, the first connection plates 121 extend along the second direction, and the two extension ends are respectively fixed to the two first enclosure portions 11. Each first reinforcement plate 122 is arranged between two adjacent first connection plates 121 and has four connection ends, two of which are fixed to one of the two adjacent first connection plates 121, and the other two connection ends are fixed to the other of the two adjacent first connection plates 121.

[0085] It can be understood that by connecting the two first enclosure parts 11 together through multiple first connecting plates 121, the outer door frame 10 can form a stable frame structure to support the inner door frame 20 and the accessories 100b thereon. In addition, the first reinforcing plate 122 can further strengthen the connection strength between the two first enclosure parts 11, and at the same time, the first connecting plates 121 can be connected together, thereby further strengthening the overall structural strength of the outer door frame 10. When the outer door frame 10 is subjected to off-load force, the first reinforcing plate 122 can also effectively prevent the outer door frame 10 from shearing.

[0086] In this embodiment, the number of the first reinforcing plates 122 is not limited, and they can be disposed between two adjacent first connecting plates 121 according to actual needs.

[0087] Combination Figure 4As shown, each inner door frame 20 includes two second enclosure parts 21 and a second connecting part 22. The two second enclosure parts 21 are arranged at intervals along the second direction. The second connecting part 22 is arranged between the two second enclosure parts 21, and the opposite ends are respectively fixed to the two second enclosure parts 21. The outer walls of the two second enclosure parts 21 are respectively connected to the inner walls of the two first enclosure parts 11 in a sliding manner.

[0088] It can be understood that the two second enclosure parts 21 are connected together through the second connecting part 22, so that the inner mast 20 can form a stable frame structure to carry the accessories 100b thereon. In addition, the sliding connection between the inner mast 20 and the outer mast 10 can be achieved through the cooperation between the first enclosure part 11 and the second enclosure part 21, so that the inner mast 20 can move in the height direction along the outer mast 10.

[0089] Combination Figure 4 As shown, the second connection portion 22 includes a plurality of second connection plates 221 and at least one second reinforcing plate 222. The plurality of second connection plates 221 are arranged at intervals along the height direction, the second connection plates 221 extend along the second direction, and the two extending ends are respectively fixed to the two second enclosure portions 21. Each second reinforcing plate 222 is arranged between two adjacent second connection plates 221 and has four connection ends, two of which are fixed to one of the two adjacent second connection plates 221, and the other two are fixed to the other of the two adjacent second connection plates 221.

[0090] It can be understood that by connecting the two second enclosure parts 21 together through multiple second connecting plates 221, the inner door frame 20 can form a stable frame structure to carry the accessories 100b thereon. In addition, the second reinforcing plate 222 can further strengthen the connection strength between the two second enclosure parts 21. At the same time, multiple second connecting plates 221 can be connected together, thereby further strengthening the overall structural strength of the inner door frame 20. When the inner door frame 20 is under off-load force, the second reinforcing plate 222 can also effectively prevent the outer door frame 10 from shearing.

[0091] In this embodiment, the number of the second reinforcing plates 222 is not limited, and they can be disposed between two adjacent second connecting plates 221 according to actual needs.

[0092] Figure 5 Schematic diagram of the three-dimensional structure of the second connecting plate in this embodiment.

[0093] Combination Figure 5As shown, part or all of the second connecting plate 221 is a reinforcing beam, and the reinforcing beam includes a middle connecting plate 221a and two side plates 221b. The middle connecting plate 221a is arched toward the side close to the first connecting portion 12. The two side plates 221b are fixed to the two ends of the middle connecting plate 221a in the height direction, and the side plates 221b are arched toward the direction close to the first connecting portion 12. A convex portion extending toward the direction close to the first connecting portion 12 is formed in the middle of the side plate 221b.

[0094] It can be understood that since the side panel 221b is arched toward the direction close to the first connection portion 12, and a convex portion extending toward the direction close to the first connection portion 12 is formed in the middle portion of the side panel 221b, the load-bearing capacity of the reinforcing beam in the horizontal direction is effectively improved compared to an ordinary rectangular plate of the same weight.

[0095] Combination Figure 1 to Figure 2 As shown, the handling equipment 100 further includes two attachments 100 b , and each attachment 100 b corresponds to an inner mast 20 .

[0096] It can be understood that the gantry 100a is capable of forking or transferring two pallets at a time, which effectively improves efficiency.

[0097] Combination Figure 1 to Figure 2 As shown, the attachment 100b is movably mounted on the side of the corresponding inner door frame 20 facing away from the outer door frame 10, and the two attachments 100b can be moved in the height direction respectively.

[0098] It can be understood that the attachment 100b is able to move in the height direction relative to the inner mast 20, so that the attachment 100b cooperates with the inner mast 20 to form a two-stage movement, and the attachment 100b has a larger movement stroke in the height direction.

[0099] Figure 6 Schematic diagram of the three-dimensional structure of the linkage mechanism in this embodiment.

[0100] Combination Figure 6 As shown, the handling device 100 further includes two sets of linkage mechanisms 100c, each linkage mechanism 100c corresponds to an attachment 100b, and each linkage mechanism 100c includes two sprockets 41 and two chains 42. The two sprockets 41 are rotatably arranged at the top positions in the height direction on the two inner door frames 20, respectively, and the rotation planes of the sprockets 41 are parallel to the first direction. Each chain 42 corresponds to a sprocket 41, and the chain 42 is wound around the corresponding sprocket 41. One end of the chain 42 extends downward along the height direction to be fixed to the outer door frame 10, and the other end extends downward along the height direction to be fixed to the corresponding attachment 100b.

[0101] It can be understood that when the inner mast 20 moves in the height direction, it can drive the sprocket 41 thereon to move synchronously. Since one end of the chain 42 is fixed to the outer mast 10, when the sprocket 41 moves with the inner mast 20, it can pull the chain 42 to move the accessory 100b upward in the height direction, or release the chain 42 to move the accessory 100b downward under the action of gravity, thereby realizing the linkage between the accessory 100b and the inner mast 20, and the accessory 100b and the inner mast 20 are 2:1 in rising height coordination.

[0102] Figure 7 Schematic diagram of the three-dimensional structure of the second rolling unit in this embodiment.

[0103] Combination Figure 7 As shown, the handling equipment 100 also includes two sets of second position limiting guide mechanisms 100d. Each second position limiting guide mechanism 100d corresponds to an attachment 100b, and each second position limiting guide mechanism 100d includes a second guide rail 51 and a plurality of second rolling units 52. The second guide rail 51 is fixed to one end of the inner door frame 20 facing away from the first connecting portion 12, and extends in the height direction. A plurality of second rolling units 52 are arranged on one end of the attachment 100b facing the inner door frame 20, and are arranged at intervals in the height direction. Each second rolling unit 52 includes a second roller mounting seat 521 and two second rollers 522. The second roller mounting seat 521 is fixed to the attachment 100b. The two second rollers 522 are rotatably arranged on the second roller mounting seat 521, and are arranged at intervals in the second direction. The circumferential surfaces of the two second rollers 522 are respectively in contact with two opposite surfaces on the second guide rail 51.

[0104] It can be understood that when the accessory 100b moves in the height direction, it can drive the multiple second rolling units 52 thereon to move synchronously, so that the two second rollers 522 in each second rolling unit 52 move along the second guide rail 51, thereby ensuring the stability of the accessory 100b when moving in the height direction and effectively avoiding shaking.

[0105] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
