The clamping structure comprises a hoisting ring, an opening and closing piece connected with the hoisting ring, a connecting piece, a first clamping piece and a second clamping piece, wherein the first clamping piece and the second clamping piece are crossed with each other; under the condition that the opening and closing piece is subjected to upward pulling force, the opening and closing distance of the opening and closing piece is reduced; due to the fact that the two ends of the opening and closing piece are connected with the first clamping piece and the second clamping piece respectively, the clamping distance between the first clamping piece and the second clamping piece becomes small. And the first clamping piece and the second clamping piece are used for clamping the to-be-clamped object and providing clamping force for the to-be-clamped object.

Description

Technical Field

[0001] The present application relates to the technical field of lifting tools, and in particular to a clamping structure and a lifting device for a foil roll. Background Art

[0002] Roll-shaped materials, such as positive and negative electrode foil materials in the battery cell workshop, are usually placed in wooden boxes. After the materials arrive at the battery cell workshop, the foil rolls need to be transferred from the wooden boxes to the foil cache rack.

[0003] Usually two slings are used to manually bind or wrap the slings on both sides of the foil roll, and then the slings and the foil roll are lifted by electric hoists and lifting devices and transferred to the foil buffer rack. In this process, it is easy to bind or wrap in place, which is less safe; the handling efficiency is low, the labor intensity is high, and it is difficult to meet the needs of efficient production. Utility Model Content

[0004] In view of this, an object of the embodiments of the present application is to provide a clamping structure and a foil roll lifting device to solve the technical problems of low safety and efficiency in existing clamping operations.

[0005] In a first aspect, an embodiment of the present application provides a clamping structure, which comprises: a lifting ring, an opening and closing piece connected to the lifting ring, a connecting piece, a first clamping piece and a second clamping piece that cross each other; wherein the first clamping piece and the second clamping piece are rotatably connected through the connecting piece;

[0006] One end of the opening and closing member is connected to one end of the first clamping member, and the other end of the opening and closing member is connected to one end of the second clamping member;

[0007] The opening and closing member is configured so that when the lifting ring is subjected to an upward pulling force, the opening and closing distance is reduced;

[0008] The first clamping member and the second clamping member are configured such that when the opening and closing distance is reduced, the clamping distance between the first clamping member and the second clamping member is reduced to clamp the object to be clamped and provide a clamping force for the object to be clamped; wherein the clamping force is directed toward the object to be clamped.

[0009] In the above implementation process, the clamping structure includes a lifting ring, an opening and closing piece connected to the lifting ring, a connecting piece, a first clamping piece and a second clamping piece that cross each other; when the opening and closing piece is subjected to an upward pulling force, the opening and closing distance of the opening and closing piece will be reduced; since the two ends of the opening and closing piece are respectively connected to the first clamping piece and the second clamping piece, the clamping distance between the first clamping piece and the second clamping piece will be reduced; the first clamping piece and the second clamping piece are used to clamp the object to be clamped, and a clamping force is provided for the object to be clamped. Based on the above clamping structure, the clamping of the object to be clamped can be achieved quickly and accurately, and the transportation efficiency and safety of the object to be clamped are improved. The technical problem of low safety and efficiency under the existing clamping operation is solved.

[0010] Optionally, in an embodiment of the present application, the clamping structure also includes: a first anti-slip member and a second anti-slip member; the first anti-slip member is arranged on the inner side of the other end of the first clamping member, and the second anti-slip member is arranged on the inner side of the other end of the second clamping member, and the inner side shapes of the first anti-slip member and the second anti-slip member are adapted to the shape of the object to be clamped; the first clamping member and the second clamping member are specifically configured so that when the opening and closing distance is reduced, the clamping distance between the first clamping member and the second clamping member is reduced, so as to contact and clamp the object to be clamped through the first anti-slip member and the second anti-slip member.

[0011] In the above-mentioned implementation process, since the inner shapes of the first anti-slip member and the second anti-slip member are adapted to the shape of the object to be clamped, and the first clamping member and the second clamping member are specifically configured so that when the opening and closing distance is reduced, the clamping distance between the first clamping member and the second clamping member is reduced, so that the object to be clamped can be contacted and clamped by the first anti-slip member and the second anti-slip member; through the first anti-slip member and the second anti-slip member whose inner shapes are adapted to the shape of the object to be clamped, the object to be clamped can be clamped more stably, and the object to be clamped can be better prevented from slipping, so as to improve the safety of the object to be clamped during transportation.

[0012] Optionally, in an embodiment of the present application, the opening and closing piece includes: a first connecting rod and a second connecting rod symmetrically arranged compared to the hanging ring; one end of the first connecting rod and the second connecting rod are rotatably connected to the hanging ring to form the opening and closing piece; the other end of the first connecting rod is rotatably connected to one end of the first clamping piece, and the other end of the second connecting rod is rotatably connected to one end of the second clamping piece.

[0013] In the above implementation process, since the opening and closing member includes a symmetrically arranged first link and a second link, and one end of the first link and the second link is rotatably connected to the lifting ring, when the lifting ring is subjected to an upward pulling force, one end of the first link and the second link will rotate relative to the lifting ring, resulting in a closer distance between the other ends of the first link and the second link, and the opening and closing distance will be reduced. Since "the other end of the first link is rotatably connected to one end of the first clamping member, and the other end of the second link is rotatably connected to one end of the second clamping member", when the distance between the other ends of the first link and the second link is closer, the distance between one end of the first clamping member and the second clamping member will become smaller, thereby resulting in a smaller clamping distance between the other ends of the first clamping member and the second clamping member, so as to clamp the object to be clamped and provide a clamping force for the object to be clamped.

[0014] Optionally, in an embodiment of the present application, one of the end portion of the other end of the first clamping member and the end portion of the other end of the second clamping member is provided with a detachable connecting hole; the other of the end portion of the other end of the first clamping member and the end portion of the other end of the second clamping member is provided with a detachable connecting member; the detachable connecting hole and the detachable connecting member are configured to form a detachable connecting structure, and the detachable connecting structure is used to fix the object to be clamped.

[0015] In the above implementation process, the detachable connection structure can maintain the clamping distance between the first clamping member and the second clamping member even in the event of accidental shaking, thereby further improving the safety of the object to be clamped during transportation.

[0016] Optionally, in an embodiment of the present application, the clamping structure also includes: a first detachable connecting member and a second detachable connecting member; the first anti-slip member is detachably arranged on the inner side of the other end of the first clamping member through the first detachable connecting member; the second anti-slip member is detachably arranged on the inner side of the other end of the second clamping member through the second detachable connecting member.

[0017] In the above implementation process, the first anti-slip part is detachably arranged on the inner side of the other end of the first clamping part through the first detachable connecting part, and the second anti-slip part is detachably arranged on the inner side of the other end of the second clamping part through the second detachable connecting part; the first anti-slip part and the second anti-slip part can be easily replaced to be suitable for a variety of objects to be clamped.

[0018] Optionally, in the embodiment of the present application, the inner sides of the first anti-slip component and the second anti-slip component include nylon material.

[0019] In the above implementation process, nylon material has the characteristics of high mechanical strength and good fatigue resistance; since the inner sides of the first anti-slip part and the second anti-slip part include nylon material, the deformation of the first and second anti-slip parts can be avoided during the transportation of the clamped object, thereby improving the stability and safety during the transportation process; the service life of the first and second anti-slip parts can also be improved.

[0020] In the second aspect, an embodiment of the present application further provides a lifting device for a foil roll, the lifting device comprising: at least one clamping structure as described in any one of the first aspects above; wherein at least two of the clamping structures are respectively arranged at the two ends of the foil roll in the axial direction, and the inner side shapes of the first clamping member and the second clamping member in the clamping structure are adapted to the shapes of the two ends of the foil roll in the axial direction.

[0021] In the above implementation process, the clamping structure is arranged at the two ends of the foil roll in the axial direction to more smoothly achieve the clamping and transportation of the foil roll; in addition, since the inner shapes of the first clamping member and the second clamping member are adapted to the shapes of the two ends of the foil roll in the axial direction, the foil roll can be clamped more stably.

[0022] Optionally, in an embodiment of the present application, the number of the clamping structures is 2; the lifting device also includes: a sling arranged parallel to the axial direction of the foil roll; a first lifting ring and a second lifting ring are respectively provided at both ends of the sling in a direction parallel to the axial direction of the foil roll; the clamping structure is symmetrically hung on the sling through the first lifting ring and the second lifting ring, respectively.

[0023] In the above implementation process, the clamping structure can be stably and symmetrically hung on the sling based on the first lifting ring and the second lifting ring, so that the foil roll can be transported by lifting the sling, and the stability and safety of the foil roll during transportation can be improved.

[0024] Optionally, in an embodiment of the present application, the distance between the first hanging ring and the second hanging ring is positively correlated with the length of the foil roll.

[0025] In the above implementation process, the distance between the first lifting ring and the second lifting ring is positively correlated with the length of the foil roll, and the clamping structure can be hung on the sling more stably based on the first lifting ring and the second lifting ring.

[0026] Optionally, in an embodiment of the present application, the lifting device further includes: a lifting device and a hanging ring arranged at a center position of the lifting device in a direction parallel to the axial direction of the foil roll; the hook of the lifting device is configured to connect the hanging ring during lifting.

[0027] In the above implementation process, by connecting the hook of the lifting equipment with the hanging ring arranged at the center position of the sling (in a direction parallel to the axial direction of the foil roll), the clamping structure arranged at both ends of the sling can be lifted based on the lifting equipment and the sling, and then the foil roll can be clamped and transported based on the clamping structure.

[0028] The beneficial effects of the present application are as follows: a clamping structure and a lifting device for a foil roll are provided, comprising a lifting ring, an opening and closing piece connected to the lifting ring, a connecting piece, a first clamping piece and a second clamping piece that cross each other; when the opening and closing piece is subjected to an upward pulling force, the opening and closing distance of the opening and closing piece will be reduced; since the two ends of the opening and closing piece are respectively connected to the first clamping piece and the second clamping piece, the clamping distance between the first clamping piece and the second clamping piece will be reduced; the first clamping piece and the second clamping piece are used to clamp the object to be clamped, and a clamping force is provided for the object to be clamped. Based on the above-mentioned clamping structure, the clamping of the object to be clamped can be achieved quickly and accurately, thereby improving the transportation efficiency and safety of the object to be clamped.

[0037] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0038] Please refer to Figure 1 , Figure 1 The schematic diagram of a clamping structure 10 provided in an embodiment of the present application. The clamping structure 10 comprises: a lifting ring 101, an opening and closing member 102 connected to the lifting ring 101, a connecting member 103, a first clamping member 104 and a second clamping member 105 intersecting each other; wherein the first clamping member 104 and the second clamping member 105 are rotatably connected via the connecting member 103;

[0039] One end of the opening and closing member 102 is connected to one end of the first clamping member 104, and the other end of the opening and closing member 102 is connected to one end of the second clamping member 105;

[0040] The opening and closing member 102 is configured such that when the lifting ring 101 is subjected to an upward pulling force, the opening and closing distance is reduced;

[0041] The first clamping member 104 and the second clamping member 105 are configured such that when the opening and closing distance is reduced, the clamping distance between the first clamping member 104 and the second clamping member 105 is reduced to clamp the object to be clamped and provide a clamping force for the object to be clamped; wherein the clamping force is directed toward the object to be clamped.

[0042] Among them, the ring 101 can be a circular ring, an arched ring or an elliptical ring, etc., and the present application does not make specific restrictions on this. The opening and closing member 102 can be a structural member with a variable opening and closing distance, and the opening and closing distance refers to the distance between one end and the other end of the opening and closing member 102; the opening and closing member 102 can be specifically realized by a rope, a bendable elastic member or "a first connecting rod and a second connecting rod symmetrically arranged compared to the ring 101; and one end of the first connecting rod and the second connecting rod are rotatably connected to the ring 101". Among them, for the case of "the opening and closing member includes a first connecting rod and a second connecting rod symmetrically arranged compared to the ring 101; and one end of the first connecting rod and the second connecting rod are rotatably connected to the ring 101", the other end of the first connecting rod corresponds to one end of the opening and closing member 102, and the other end of the second connecting rod corresponds to the other end of the opening and closing member 102. The connecting member 103 can be realized by a pivot or a coaxial connector, etc. It should be noted that, Figure 1 It is shown that the opening and closing member 102 is realized by "a structural member including a first connecting rod and a second connecting rod which are symmetrically arranged compared to the lifting ring 101; and one end of the first connecting rod and the second connecting rod is rotatably connected to the lifting ring 101".

[0043] The intersection of the first clamping member 104 and the second clamping member 105 can be rotatably connected by the connecting member 103 (the first clamping member 104 can rotate relative to the second clamping member 105 around the connecting member 103, and the second clamping member 105 can also rotate relative to the first clamping member 104 around the connecting member 103); the specific intersection position of the first clamping member 104 and the second clamping member 105 can be adjusted according to the actual application situation. The clamping distance specifically refers to the distance between the other end of the first clamping member 104 and the other end of the second clamping member 105. When the opening and closing member 102 is subjected to an upward pulling force, the opening and closing distance of the opening and closing member 102 will be reduced; since the two ends of the opening and closing member 102 are respectively connected to the first clamping member 104 and the second clamping member 105, the distance between one end of the first clamping member 104 and one end of the second clamping member 105 will be reduced; since the first clamping member 104 and the second clamping member 105 intersect with each other, the distance between one end of the first clamping member 104 and one end of the second clamping member 105 will be reduced, which will cause the clamping distance between the other end of the first clamping member 104 and the other end of the second clamping member 105 to be reduced. The clamping force provided by the first clamping member 104 is directed toward the object to be clamped and the second clamping member 105, and the clamping force provided by the second clamping member 105 is directed toward the object to be clamped and the first clamping member 104. The materials of the lifting ring 101, the opening and closing member 102, the connecting member 103, the first clamping member 104 and the second clamping member 105 can be the same or different, and can be alloy, steel or copper. The object to be clamped can be a foil roll, steel, or other objects to be transported.

[0044] It can be seen that the clamping structure provided by the embodiment of the present application includes: a lifting ring 101, an opening and closing piece 102 connected to the lifting ring 101, a connecting piece 103, a first clamping piece 104 and a second clamping piece 105 that cross each other; when the opening and closing piece 102 is subjected to an upward pulling force, the opening and closing distance of the opening and closing piece 102 will be reduced; since the two ends of the opening and closing piece 102 are respectively connected to the first clamping piece 104 and the second clamping piece 105, the clamping distance between the first clamping piece 104 and the second clamping piece 105 will be reduced; the first clamping piece 104 and the second clamping piece 105 are used to clamp the object to be clamped, and a clamping force is provided for the object to be clamped. Based on the above-mentioned clamping structure, the clamping of the object to be clamped can be achieved quickly and accurately, thereby improving the transportation efficiency and safety of the object to be clamped. It solves the technical problem of low safety and efficiency under the existing clamping operation.

[0045] Please refer to Figure 2 , Figure 2 A schematic structural diagram of another clamping structure 20 provided in an embodiment of the present application.

[0046] In some optional embodiments, the clamping structure 20 also includes: a first anti-slip member 106 and a second anti-slip member 107; the first anti-slip member 106 is arranged on the inner side of the other end of the first clamping member 104, and the second anti-slip member 107 is arranged on the inner side of the other end of the second clamping member 105, and the inner side shapes of the first anti-slip member 106 and the second anti-slip member 107 are adapted to the shape of the object to be clamped; the first clamping member 104 and the second clamping member 105 are specifically configured so that when the opening and closing distance is reduced, the clamping distance between the first clamping member 104 and the second clamping member 105 is reduced, so as to contact and clamp the object to be clamped through the first anti-slip member 106 and the second anti-slip member 107.

[0047] Among them, the anti-slip materials of the first anti-slip member 106 and the second anti-slip member 107 can be the same or different; specifically, they can be nylon, rubber or polyvinyl chloride, etc. The inner side of the first anti-slip member 106 or the second anti-slip member 107 refers to the side close to the object to be clamped. The first anti-slip member 106 and the second anti-slip member 107 can be made entirely of anti-slip materials; or only the inner sides of the first anti-slip member 106 and the second anti-slip member 107 can be coated with corresponding anti-slip materials. Taking the shape of the object to be clamped as a circle as an example, when the clamping distance between the first clamping member 104 and the second clamping member 105 is the smallest, the inner sides of the first anti-slip member 106 and the second anti-slip member 107 can form a circle and fit the outer surface of the object to be clamped.

[0048] In some optional embodiments, the opening and closing member 102 includes: a first connecting rod 1021 and a second connecting rod 1022 which are symmetrically arranged compared to the hanging ring 101; one end of the first connecting rod 1021 and the second connecting rod 1022 are rotatably connected to the hanging ring 101 to form the opening and closing member 102; the other end of the first connecting rod 1021 is rotatably connected to one end of the first clamping member 104, and the other end of the second connecting rod 1022 is rotatably connected to one end of the second clamping member 105.

[0049] Among them, the lengths of the first connecting rod 1021 and the second connecting rod 1022 are consistent or within a preset error range. The materials of the first connecting rod 1021 and the second connecting rod 1022 can be alloy materials, steel materials or copper materials. In the case of "the opening and closing member 102 includes a first connecting rod 1021 and a second connecting rod 1022 that are symmetrically arranged compared to the ring 101; and one end of the first connecting rod 1021 and the second connecting rod 1022 is rotatably connected to the ring 101 to form the opening and closing member 102", the opening and closing distance corresponds to the distance between the other end of the first connecting rod 1021 and the other end of the second connecting rod 1022. The other end of the first connecting rod 1021 can be rotatably connected to one end of the first clamping member 104 based on a pivot or a coaxial connector, or the other end of the second connecting rod 1022 can be rotatably connected to one end of the second clamping member 105.

[0050] In some optional embodiments, one of the ends of the other end of the first clamping member 104 and the other end of the second clamping member 105 is provided with a detachable connecting hole; the other of the ends of the other end of the first clamping member 104 and the other end of the second clamping member 105 is provided with a detachable connecting member; the detachable connecting hole and the detachable connecting member are configured to form a detachable connecting structure, and the detachable connecting structure is used to fix the object to be clamped.

[0051] Among them, since a detachable connection hole is provided at one of the ends of the other end of the first clamping member 104 and the other end of the second clamping member 105, and a detachable connection piece is provided at the other of the ends of the other end of the first clamping member 104 and the other end of the second clamping member 105, a detachable connection structure can be formed through the detachable connection hole and the detachable connection piece during the transportation of the object to be clamped. Even in the case of accidental shaking, the clamping distance between the first clamping member and the second clamping member can be maintained through the detachable connection structure, further improving the safety of the object to be clamped during transportation.

[0052] In some optional embodiments, the clamping structure also includes: a first detachable connecting member and a second detachable connecting member; the first anti-slip member 106 is detachably arranged on the inner side of the other end of the first clamping member 104 through the first detachable connecting member; the second anti-slip member 107 is detachably arranged on the inner side of the other end of the second clamping member 105 through the second detachable connecting member.

[0053] The first detachable connector and the second detachable connector can be implemented in the same or different ways; specifically, they can be snap connectors or screw and nut connectors, etc. The first anti-slip member 106 is detachably arranged on the inner side of the other end of the first clamping member through the first detachable connector, and the second anti-slip member 107 is detachably arranged on the inner side of the other end of the second clamping member through the second detachable connector; the first anti-slip member and the second anti-slip member can be easily replaced to be applicable to a variety of objects to be clamped.

[0054] In some optional embodiments, the inner sides of the first anti-slip member 106 and the second anti-slip member 107 include nylon material.

[0055] Among them, nylon material has the characteristic of high mechanical strength. Since the inner sides of the first anti-slip part 106 and the second anti-slip part 107 include nylon material, the deformation of the first anti-slip part 106 and the second anti-slip part 107 can be avoided during the transportation of the object to be clamped, thereby improving the stability and safety during the transportation process; in addition, the nylon material also has the characteristic of good fatigue resistance, and can also improve the service life of the first anti-slip part 106 and the second anti-slip part 107.

[0056] Please refer to Figure 3 , Figure 3 A schematic structural diagram of a foil roll lifting device 30 provided in an embodiment of the present application.

[0057] An embodiment of the present application also provides a lifting device 30 for a foil roll, comprising: at least two clamping structures 301 as described in any one of the first aspects; wherein the at least two clamping structures 301 are respectively arranged at the two ends of the foil roll 300 in the axial direction, and the inner side shapes of the first clamping member and the second clamping member in the clamping structure 301 are adapted to the shapes of the two ends of the foil roll 300 in the axial direction.

[0058] Among them, since the two ends of the foil roll 300 in the axial direction are usually in a roll shape, the inner shapes of the first clamping member and the second clamping member can be set to an arc shape; it can be understood that when the two ends of the foil roll 300 in the axial direction are realized by other shapes, the inner shapes of the first clamping member and the second clamping member can also be set to other shapes. The number of the clamping structures 301 is an even number, which is convenient for symmetrically arranging the two ends of the foil roll 300 in the axial direction.

[0059] In some optional embodiments, the number of clamping structures 301 is 2; the lifting device 30 of the foil roll also includes: a sling 302 arranged parallel to the axial direction of the foil roll 300; the two ends of the sling 302 in a direction parallel to the axial direction of the foil roll 300 are respectively provided with a first lifting ring 303 and a second lifting ring 304; the clamping structure 301 is symmetrically hung on the sling 302 through the first lifting ring 303 and the second lifting ring 304 respectively.

[0060] Among them, the number of the first hanging ring 303 or the second hanging ring 304 can be one or more; when the number of the first hanging ring 303 and the second hanging ring 304 is multiple, and the weight of the foil roll 300 exceeds the weighing range of the two clamping structures 301, it is more convenient to replace a larger number of clamping structures 301 to realize the transportation of the corresponding foil roll 300. Figure 3 , a case where the number of the first hanging rings 303 is four and the number of the second hanging rings 304 is four is shown.

[0061] In some optional embodiments, the distance between the first suspension ring 303 and the second suspension ring 304 is positively correlated with the length of the foil roll 300 .

[0062] Among them, since the distance between the first hanging ring 303 and the second hanging ring 304 is positively correlated with the length of the foil roll 300, the clamping structure can be more stably hung on the hanger based on the first hanging ring 303 and the second hanging ring 304. Specifically, the distance between the first hanging ring 303 and the second hanging ring 304 is greater than the length of the foil in the foil roll 300, and less than the length of the roll in the foil roll 300.

[0063] In some optional embodiments, the lifting device 30 for the foil roll further includes: a lifting device and a hanging ring 305 arranged at a central position of the lifting device 302 in a direction parallel to the axial direction of the foil roll 300; the hook of the lifting device is configured to connect the hanging ring 305 during the lifting process.

[0064] The lifting device may be realized by an electric hoist, a winch or a multifunctional hoist, etc. By connecting the hook of the lifting device to the hanging ring 305 provided at the center position of the sling 302 (in a direction parallel to the axial direction of the foil roll 300), the clamping structure 301 provided at both ends of the sling 302 can be lifted based on the lifting device and the sling 302, and then the foil roll 300 can be clamped and transported based on the clamping structure 301.

[0065] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of another foil roll lifting device 40 provided in an embodiment of the present application. It can be understood that, Figure 3The figure shows the situation where the clamping structure 301 does not clamp the foil roll 300. Figure 4 What is shown in FIG. 3 is the situation where the clamping structure 301 clamps the foil roll 300. Figure 4 It can be seen that when the lifting ring is subjected to upward pulling force, the opening and closing member in the clamping structure 301 is Figure 3 When the opening and closing distance is reduced, the clamping distance between the first clamping member and the second clamping member is reduced to clamp the object to be clamped (i.e., the foil roll 300), thereby providing a clamping force for the foil roll 300 toward the object to be clamped.

[0066] It should be understood that the lifting device 30 for the foil roll corresponds to the embodiment of the clamping structure 10 / 20 described above.
