[0062] As described in the background technology, in the related art, the drag chain is prone to swinging when the fork device moves, which will not only cause the drag chain to deform but also break, reducing the safety of the cargo transfer equipment. The inventors have found that the reason for this problem is that the column is not equipped with a component to protect the drag chain. During the movement of the fork device, the drag chain will swing in the front-to-back direction relative to the column or in the left-to-right direction relative to the column, which will not only cause the drag chain to deform or even break, but also may cause the drag chain to be inserted into the fork device, causing damage to the fork device.
[0063] In view of the above technical problems, the embodiments of the present disclosure provide a device for preventing a drag chain from swinging, cargo transfer equipment and a storage system, wherein a first protective structure is arranged on a column, and the first protective structure includes a first protective member and a second protective member spaced and arranged opposite to each other along a first direction, and an accommodation space is formed between the first protective member and the second protective member. By accommodating the drag chain in the accommodation space, the drag chain is protected in the first direction by at least the first protective member and the second protective member, and the moving path of the drag chain in the first direction is constrained, thereby preventing the drag chain from swinging in the first direction, avoiding deformation or breakage of the drag chain, and improving the safety of the cargo transfer equipment.
[0064] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.
[0065] Please refer to the attached Figure 1 To Attachment Fig.15 , an embodiment of the present application provides a cargo transfer device 1000, which can be one of a handling robot, an elevator and a hoist.
[0066] Please continue to refer to the attached Figure 1 The cargo transfer equipment 1000 includes at least two columns 200, and the at least two columns 200 are arranged at intervals, for example, at least two columns 200 are arranged at intervals along the second direction. Fig.16 When the cargo transfer device 1000 is a handling robot, the bottoms of at least two columns 200 are connected to the mobile base 400, and the movement of the mobile base 400 drives at least the columns 200 to move, thereby moving the cargo transfer device 1000 to the target position. When the cargo transfer device 1000 is an elevator, the bottoms and tops of at least two columns 200 can be slidably disposed on the guide rails 500.
[0067] The cargo transfer equipment 1000 also includes a fork structure 300, which is slidably mounted on the column 200, and the fork structure 300 can move up and down along the extension direction of the column 200 to adjust the height of the fork structure 300 from the ground or the installation surface, thereby facilitating the fork structure 300 to pick up and place cargo at different heights.
[0068] In order to facilitate the description of various directions of the cargo transfer device 1000, it is convenient to describe the movement direction of the fork structure 300 as a reference. The first direction is perpendicular to the column 200, that is, the first direction is the extension / retraction direction of the fork structure 300, that is, the first direction is the extension / retraction direction of the fork structure 300. Figure 1 The second direction is perpendicular to the extension direction of the fork structure 300, and the direction in which the fork structure 300 moves along the guide rail 500 on the column 200, i.e. Figure 1 The third direction is the lifting direction of the fork structure 300, or in other words, the third direction is the extending direction of the column 200. Figure 1 The middle Z direction. The first direction, the second direction, and the third direction are perpendicular to each other.
[0069] The cargo transfer equipment 1000 further includes a drag chain anti-sway device 100, which is arranged on any column 200. In other words, the number of the drag chain anti-sway device 100 can be set according to the number of the drag chains 120. For example, the number of the drag chain anti-sway device 100 and the drag chain 120 is one, and the drag chain anti-sway device 100 is arranged on one of the columns 200. For another example, the number of the drag chain anti-sway device 100 and the drag chain 120 is two, one of the drag chain anti-sway device 100 is arranged on one of the columns 200, and the other drag chain anti-sway device 100 is arranged on the other column 200.
[0070] Please continue to refer to the attached Figure 2 The drag chain anti-sway device 100 includes a first protective structure 110 and a drag chain 120. The first protective structure 110 is used to be installed on a column 200 of the cargo transfer equipment. For example, the first protective structure 110 can be fixedly connected to the column 200 by bolts.
[0071] The first protective structure 110 at least includes a first protective member 111 and a second protective member 112. The first protective member 111 and the second protective member 112 are spaced apart and arranged opposite to each other along a first direction. The first protective member 111 and the second protective member 112 are spaced apart and arranged relative to the column 200 in the first direction to attach Figure 1 and attached Figure 2Taking the illustrated orientation as an example, the first protection member 111 and the second protection member 112 are spaced apart along the extension direction of the fork structure 300 , so that the first protection member 111 and the second protection member 112 are located in front of or behind the column 200 .
[0072] In this embodiment, the first protective member 111 can be located between the second protective member 112 and the column 200; the second protective member 112 can also be located between the first protective member 111 and the column 200; the first protective member 111 and the second protective member 112 form a accommodating space 113; the drag chain 120 is accommodated in the accommodating space 113, and one end of the drag chain 120 is connected to the first protective structure 110, and the other end of the drag chain 120 is used to connect to the fork structure 300 of the cargo transfer equipment; when the fork structure 300 moves up and down along the column 200, the drag chain 120 also moves accordingly.
[0073] It should be noted that, in this embodiment, one end of the drag chain 120 may be fixedly connected to the first protective structure 110 or detachably connected. The other end of the drag chain 120 may be directly connected to the fork structure 300 or indirectly connected. Fig.14 and attached Fig.15 The drag chain anti-sway device 100 also includes a second connecting structure 160, wherein one end of the second connecting structure 160 is connected to the fork structure 300, and the other end of the second connecting structure 160 is connected to the drag chain 120. Such a configuration can facilitate the connection between the fork structure 300 and the drag chain 120.
[0074] Given that the drag chain 120 is accommodated in the accommodating space 113, at least the first protective member 111 and the second protective member 112 are used to protect the drag chain 120 in the first direction, constraining the movement path of the drag chain 120 in the first direction, thereby preventing the drag chain 120 from swinging in the first direction, avoiding deformation or breakage of the drag chain 120, and improving the safety of the cargo transfer equipment 1000.
[0075] It should be understood that the first protective structure 110 can be an integral component, and a housing space 113 is formed in the first protective structure 110, and the parts retained in the first direction respectively constitute the first protective member 111 and the second protective member 112. The first protective structure 110 can also be a split structure, that is, the first protective member 111 and the second protective member 112 are relatively independent components, and the first protective member 111 and the second protective member 112 form the housing space 113; illustratively, the first protective member 111 and the second protective member 112 can both be protective plate structures.
[0076] Please refer to the attached Figure 3 To Attachment Figure 6In a possible implementation, at least one of the relative surfaces of the first protective member 111 and the second protective member 112 is provided with a guide groove 114; the drag chain 120 is slidably arranged in the guide groove 114, so that the guide groove 114 can be used to guide the drag chain 120, and the inner wall of the guide groove 114 in the second direction can also limit the left and right sides of the drag chain 120, thereby better limiting the swinging of the drag chain 120.
[0077] At least one of the opposing surfaces of the first guard 111 and the second guard 112 is provided with a guide groove 114, which can be understood as the number of the guide groove 114 being one or two. Specifically, in one example, the guide groove 114 is provided on the opposing surface of the first guard 111 and the second guard 112. In another example, the guide groove 114 is provided on the opposing surface of the second guard 112 and the first guard 111. In yet another example, the opposing surface of the first guard 111 and the second guard 112, and the opposing surface of the second guard 112 and the first guard 111 are both provided with guide grooves 114, so that the shapes of the first guard 111 and the second guard 112 are both U-shaped. In this way, the swinging of the drag chain 120 in the second direction can be limited, and the preparation of the first guard 111 and the second guard 112 can be facilitated.
[0078] Please continue to refer to the attached Figure 2 In the second direction, there is a preset distance between the inner wall of the guide groove 114 and the drag chain 120. The second direction X is perpendicular to the first direction Y. The first direction is the extension direction of the fork structure 300, and the second direction is perpendicular to the extension direction of the fork structure 300.
[0079] That is, the left and right sides of the drag chain 120 may not contact the inner wall of the guide groove 114. In this way, the friction between the inner wall of the guide groove 114 and the left and right sides of the drag chain 120 is reduced, and the wear of the drag chain 120 is reduced, while the smoothness of the sliding of the drag chain 120 in the guide groove 114 can be ensured. It should be noted that the value of the preset spacing can be freely set according to the size of the guide groove 114 and the drag chain 120.
[0080] It should be understood that the first guard 111 and the second guard 112 can both be U-shaped channel steels. For example, the first guard 111 and the second guard 112 both include a first guard plate and a second guard plate and a third guard plate arranged on both sides of the first guard plate, wherein the first guard plate and the second guard plate are perpendicular to each other, and the first guard plate and the third guard plate are perpendicular to each other; the first guard plate, the second guard plate and the third guard plate form a guide groove 114.
[0081] Please continue to refer to the attached Figure 3 To Attachment Figure 6In the third direction, at least one end of the first protective member 111 and the second protective member 112 is provided with a first guide plate 117, and the first guide plate 117 is inclined in a direction away from the accommodating space 113; wherein the third direction is the height direction of the column 200, that is, the third direction is perpendicular to the first direction.
[0082] Since the first guide plate 117 on the first protective member 111 and the second protective member 112 are arranged in the same manner, the arrangement position of the first guide plate 117 is described by taking the first protective member 111 as an example.
[0083] Exemplarily, in the third direction, the first protective member 111 has a first end and a second end that are oppositely disposed, wherein the first end may be the top of the first protective member 111, and the second end may be the bottom of the first protective member 111. At least one of the first end and the second end is provided with a first guide plate 117, or both of the first end and the second end are provided with the first guide plate 117.
[0084] The first guide plate 117 is tilted away from the accommodating space 113, that is, the end of the first guide plate 117 away from the first protective member 111 is tilted away from the guide groove 114, so that the space enclosed by the first guide plate 117 is larger than the guide groove 114; thereby facilitating the installation of the drag chain 120 into the guide groove 114 of the first protective member 111, and the surface of the first guide plate 117 plays a guiding function, which is more conducive to the installation of the drag chain 120.
[0085] The first guide plate 117 may be an integral annular structure, that is, the shape of the first guide plate 117 is also similar to a U-shape, and the first guide plate 117 is connected to the first end and / or the second end. The first guide plate 117 may also be a split structure, for example, please refer to the attached Figure 4 The first guide plate 117 includes three parts, and there is no connection between the three parts. With this arrangement, the first guide plate 117 can be integrally formed by injection molding or other processes, which can facilitate the preparation of the first guide plate 117 and improve the structural strength of the first protective member 111.
[0086] It should be understood that the first protective structure 110 can be directly connected to the column 200 or indirectly connected. Figure 2 , Attachment Figure 7 and attached Figure 8The drag chain anti-sway device 100 further includes a first connection structure 130, and the first protective structure 110 is installed on the column 200 through the first connection structure 130. The first connection structure 130 extends along the first direction, and the first protective member 111 and the second protective member 112 are arranged on the first connection structure 130 at intervals along the first direction. Such an arrangement can facilitate the installation of the first protective member 111 and the second protective member 112, and improve the convenience of disassembly and assembly of the first protective member 111 and the second protective member 112.
[0087] The first connection structure 130 may be a connection plate extending entirely along the first direction, one end of the connection plate is fixedly connected to the column 200, and the first protection member 111 and the second protection member 112 are fixedly connected to one side of the column 200. The first connection structure 130 may also be other structures.
[0088] Please continue to refer to the attached Figure 7 The first connection structure 130 includes a first mounting portion 131, a second mounting portion 132 and a guide portion 133. The first mounting portion 131 and the second mounting portion 132 are spaced apart along the first direction; the guide portion 133 is located between the first mounting portion 131 and the second mounting portion 132, and is connected to the first mounting portion 131 and the second mounting portion 132 respectively, so that the first mounting portion 131, the second mounting portion 132 and the guide portion 133 form a U-shaped structure.
[0089] Please continue to refer to the attached Figure 4 and attached Figure 6 The first protection member 111 includes a first bending portion 115 extending along the second direction; that is, the second protection plate of the first protection member 111 is bent away from the edge of the first protection plate along the second direction to form the first bending portion 115. The second protection member 112 includes a second bending portion 116 extending along the second direction, and the second protection plate of the second protection member 112 is bent away from the edge of the first protection plate along the second direction to form the second bending portion 116; the first bending portion 115 and the second bending portion 116 are arranged opposite to each other.
[0090] The first mounting portion 131 cooperates with the first bending portion 115 and is detachably connected; that is, the first bending portion 115 and the first mounting portion 131 fit together and are fixed together by bolts. Correspondingly, the second mounting portion 132 cooperates with the second bending portion 116 and is detachably connected; that is, the second bending portion 116 and the second mounting portion 132 fit together and are fixed together by bolts. Such a configuration can increase the contact area between the first protective member 111 and the first connecting structure 130, and increase the contact area between the second protective member 112 and the first connecting structure 130, thereby increasing the connection strength between the first protective structure 110 and the first connecting structure 130.
[0091] In addition, the guide portion 133 cooperates with the side of the drag chain 120 in the second direction. The guide portion 133 can be disposed on the side of the drag chain 120 in the second direction to prevent the drag chain 120 from swinging in the second direction; and can also play a guiding function to ensure smooth movement of the drag chain 120 in the third direction.
[0092] Please continue to refer to the attached Figure 7 and attached Figure 8 As a possible implementation of the first connection structure 130, the first connection structure 130 includes a first connection plate 134, a second connection plate, a third connection plate and a fourth connection plate connected in sequence, and each of them is perpendicular to each other; the second connection plate and the fourth connection plate are parallel to each other and arranged opposite to each other; the second connection plate constitutes a first mounting portion 131, the fourth connection plate constitutes a second mounting portion 132, and the third connection plate constitutes a guide portion 133 toward the side of the drag chain 120.
[0093] That is, the third connecting plate extends along the first direction, and the second connecting plate and the fourth connecting plate are respectively arranged on one side of the third connecting plate and are respectively perpendicular to the third connecting plate, so that the second connecting plate, the third connecting plate and the fourth connecting plate form a U-shaped structure. The first connecting plate 134 is fixedly connected to the end of the second connecting plate away from the third connecting plate, and the first connecting plate 134 is perpendicular to the second connecting plate.
[0094] It should be noted that the end of the first connecting plate 134 away from the second connecting plate can be directly connected to the column 200, but in order to facilitate the fixed connection between the first connecting plate 134 and the column 200, the end of the first connecting plate 134 away from the second connecting plate provided in this embodiment is bent to form a bent section 1341, and the bent section 1341 is parallel to the second connecting plate and the fourth connecting plate. In this way, the contact area between the column 200 and the first connecting structure 130 can be increased, and the connection strength between the first connecting structure 130 and the column 200 can be improved.
[0095] In this embodiment, the first connection structure 130 further includes a reinforcing plate 135 , one end of the reinforcing plate 135 is connected to the first connection plate 134 , and the other end of the reinforcing plate 135 is connected to the fourth connection plate to improve the structural strength of the first connection structure 130 .
[0096] In one possible implementation, please refer to the attached Figure 2 , Attachment Fig. 9 and attached Fig.10 The drag chain anti-sway device 100 also includes a second protective structure 140, one end of the second protective structure 140 is connected to the column 200, for example, one end of the second protective structure 140 is fixedly connected to the column 200 by bolts.
[0097] The second protective structure 140 and the first connecting structure 130 are located on both sides of the drag chain 120. That is, in the second direction X, the first connecting structure 130 and the second protective structure 140 are respectively located on both sides of the drag chain 120, that is, the first connecting structure 130 and the second protective structure 140 are respectively located on the left and right sides of the drag chain 120, and cooperate with the first protective member 111 and the second protective member 112 to limit and guide the drag chain 120 from four directions, front, back, left and right, to prevent the drag chain 120 from swinging in the first direction and the second direction, and to prevent the drag chain 120 from escaping from the accommodating space 113, thereby improving the safety of the drag chain 120.
[0098] Among them, the second protective structure 140 can be a plate-like body extending along the first direction, or can be other structures. Exemplarily, the second protective structure 140 includes a connecting portion 141 and a protective portion 142. The protective portion 142 extends along the first direction, that is, the protective portion 142 extends along the extension direction of the fork structure 300, and the protective portion 142 forms a guide surface opposite to the guide portion 133 toward the side of the drag chain 120; the guide surface cooperates with the side of the drag chain 120 in the second direction. The guide surface can be blocked on the side of the drag chain 120 in the second direction to prevent the drag chain 120 from swinging in the second direction; it can also play a guiding function to ensure the smooth movement of the drag chain 120 in the third direction.
[0099] The connecting portion 141 is disposed at one end of the protective portion 142 and intersects with the protective portion 142; for example, the connecting portion 141 and the protective portion 142 are perpendicular to each other, so that the second protective structure 140 forms an L shape. The connecting portion 141 is detachably connected to the column 200, for example, the connecting portion 141 and the column 200 are fixedly connected together by bolts. In this way, the connection strength between the column 200 and the second protective structure 140 can be improved.
[0100] Please continue to refer to the attached Fig. 9 and attached Fig.10 At least one end of the protection portion 142 in the third direction is bent in a direction away from the drag chain 120 to form a third bent portion 143. Figure 2 Taking the position shown as an example, the upper and lower ends of the protective part 142 are bent away from the drag chain 120, wherein the third bent portion 143 and the protective part 142 are inclined, and the angle between the two is an obtuse angle. This is conducive to reducing the contact area between the second protective structure 140 and the drag chain 120, and reducing the wear on the drag chain 120.
[0101] In one possible implementation, please attach Figure 1 , see attached Fig.11 To Attachment Fig.13The drag chain anti-sway device 100 further includes a guide structure 150, which is disposed on the column 200 and is at least located on one side of the first protective structure 110 in the third direction of the drag chain 120. For example, the length of the first protective structure 110 in the third direction is less than the height of the column 200, and the guide structure 150 is located above and / or below the first protective structure 110 to attach Figure 1 Taking the illustrated orientation as an example, the guide structure 150 is located above the first protective structure 110. When the guide structure 150 is located above and below the first protective structure 110 at the same time, the reliability of the drag chain anti-sway device 100 can be improved.
[0102] The guide structure 150 includes a guide hole 151, which penetrates the guide structure 150 along the third direction and is used for the drag chain 120 to pass through. The guide structure 150 can constrain and guide the four surfaces of the drag chain 120 to further prevent the drag chain 120 from swinging.
[0103] In this embodiment, the number of the guide structures 150 can be one or more. When the number of the guide structures 150 is more than one, the multiple guide structures 150 are arranged at intervals along the column 200. The spacing between adjacent guide structures 150 can be adjusted according to the rigidity of the drag chain 120; for example, when the rigidity of the drag chain 120 is better, the spacing between the guide structures 150 can be set larger, so that the weight of the cargo handling device can be reduced.
[0104] Please continue to refer to the attached Fig.12 The guide structure 150 includes a fixed section 152 and a guide section 153 connected to the fixed section 152. The fixed section 152 is fixedly connected to the column 200. The fixed section 152 is fixedly connected to the column 200 by bolts.
[0105] The end of the guide section 153 away from the fixed section 152 is bent around the circumference of the drag chain 120 to form a guide hole 151. The guide section 153 is formed by bending the fixed section 152, so that the fixed section 152 and the guide section 153 are integrally formed, which reduces the difficulty of preparing the guide structure 150 and improves the structural strength of the guide structure 150.
[0106] At least one of the ends of the guide section 153 in the third direction is provided with a second guide plate 154 . The second guide plate 154 extends in a direction away from the guide hole 151 , and an angle between the second guide plate 154 and the guide section 153 is an obtuse angle.
[0107] The area of the space enclosed by the second guide plate 154 is larger than the area of the guide hole 151 , which is beneficial for the installation of the drag chain 120 into the guide hole 151 . The surface of the second guide plate 154 serves as a guide, which is more beneficial for the installation of the drag chain 120 .
