[0006] In the technical solution of the present application, the first face of the bearing part for bearing the lifting object is designed as a plane, which can increase the contact stress area between the lifting tool and the lifting object, and alleviate the deformation problem of the lifting hole of the lifting object during lifting, compared with a curved surface or other faces.

[0007] In some embodiments, the first face is a face perpendicular to a first direction, wherein the first direction is the direction of gravity.

[0008] In the technical solution of the present application, the first face is perpendicular to the direction of gravity during lifting. By designing the face as a plane, the contact stress area between the lifting tool and the lifting object can be increased, and the deformation problem of the lifting hole of the lifting object during lifting can be alleviated.

[0009] In some embodiments, the lifting tool further comprises a main body part, and the lifting hook is protruded on a second face of the main body part, wherein the second face is a plane, and the second face is perpendicular to the first face.

[0010] In the technical solution of the present application, the lifting hook is protruded on the second face of the main body part. By designing the second face as a plane, the lifting object can not shake due to the concave-convex of the second face during lifting, so that the lifting object is more stable during lifting.

[0011] In some embodiments, the lifting hook and the main body part are integrally formed.

[0012] The technical scheme of the embodiment of the present application can alleviate the problem of breakage of the hook and the main body caused by the excessive weight of the hoisted object in the process of hanging and hoisting the object.

[0013] In some embodiments, the hook further comprises a stop portion, which is arranged at one end of the bearing portion away from the main body.

[0014] The technical scheme of the embodiment of the present application can prevent the problem of falling and unstable hanging of the hoisted object in the process of hanging.

[0015] In some embodiments, the surface of the bearing portion opposite to the first surface is flush with the stop portion.

[0016] In some embodiments, the size of the bearing portion along the first direction is smaller than the size of the stop portion along the first direction.

[0017] The technical scheme of the embodiment of the present application is that the size of the stop portion along the first direction is greater than the size of the bearing portion along the first direction, that is, the stop portion is higher than the bearing portion, which is used to prevent the problem of falling and unstable hoisting of the hoisted object.

[0018] In some embodiments, the size of the bearing portion along the first direction ranges from 1 cm to 2 cm.

[0019] In some embodiments, the first surface is printed with a pattern.

[0020] The technical scheme of the embodiment of the present application is that the pattern on the first surface can make the cooperation between the hoisting hole of the hoisted object and the surface of the first surface more firm, and the hoisting process is more stable.

[0021] In some embodiments, the distance from the first surface of the bearing portion to the edge of the main body along the direction opposite to the first direction ranges from 10 cm to 30 cm.

[0022] The technical scheme of the embodiment of the present application is that the distance from the bearing portion to the edge of the main body along the direction opposite to the first direction can make the hoisting process more stable and reduce the shaking of the hoisted object.

[0023] In some embodiments, the distance from the bearing portion to the edge of the main body along the second direction ranges from 5 cm to 10 cm, wherein the second direction is perpendicular to the first direction.

[0024] The technical scheme of the embodiment of the present application is that the distance from the bearing portion to the edge of the main body along the second direction can make the hoisting process more stable and reduce the shaking of the hoisted object.

[0025] In some embodiments, the stop portion is connected to the bearing portion perpendicularly.

[0026] In the technical solution of the embodiment of the application, the vertical connection between the stop portion and the bearing portion can better prevent the hoisting object from being unstable or shaking during hoisting.

[0027] In some embodiments, the hoisting tool further comprises two symmetrically distributed lifting columns protruding on a third face of the main body portion, wherein the third face is parallel to the first face, and the hooks are two, which are symmetrically distributed about an axis, and are used to bear the hoisting object.

[0028] In the technical solution of the embodiment of the application, the lifting columns are designed on the second face of the main body portion, which are used to be connected with hoisting equipment (such as various types of cranes) during hoisting, and play a role of lifting. By installing two hooks on both sides of the hoisting object, i.e., two lifting columns, which are used to lift the hoisting object, for each lifting column, the opposite hook is provided, which is used to more stably hang the hoisting object.

[0029] In some embodiments, the lifting columns are integrally formed with the main body portion.

[0030] In the technical solution of the embodiment of the application, through the design of integral forming, the problem of fracture of the lifting columns and the main body portion due to the too large weight of the hoisting object during hanging the hoisting object can be reduced.

[0031] In some embodiments, the hoisting object borne by the hooks is an electrical box.

[0073] At present, with the increasing size and weight of the energy storage device, the hoisting of the larger storage device is also more and more challenging. In the process of hoisting the larger storage device, the lifting hole of the larger storage device is usually hoisted by using a lifting tool to hang the lifting hole of the large electric box, so as to realize hoisting. With the increase of the size and weight of the storage device, the lifting hole of the larger storage device is in line contact with the lifting tool in the process of hoisting, and the lifting hole of the storage device is prone to deformation in the process of line contact hoisting. It should be understood that in the present application, the energy storage device is an energy storage container or an energy storage cabinet, or it is referred to as an electric box.

[0074] In order to alleviate the problem that the electrical box is prone to deformation during hoisting, the line contact between the lifting appliance and the electrical box can be replaced with surface contact to increase the contact stress area between the lifting appliance and the electrical box during hoisting, thereby alleviating the problem of deformation of the electrical box lifting hole during hoisting.

[0075] Based on the above considerations, in order to solve the problem of deformation of the electrical box lifting hole during hoisting, the present application provides a lifting appliance, which comprises a lifting hook, and the lifting hook comprises a bearing part for bearing a hoisted object, wherein the first surface of the bearing part for bearing the hoisted object is a plane. The present application increases the contact stress area between the bearing part and the hoisted object by designing the first surface of the bearing part to be a plane, thereby alleviating the problem of deformation of the lifting hole of the hoisted object during hoisting.

[0076] The technical solutions described in the embodiments of the present application are applicable to the scene of hoisting various hoisted objects by a lifting appliance, wherein the lifting appliance can hoist any hoisted object, and the above is described by taking an electrical box as an example, and the present application does not limit the specific content of the hoisted object.

[0077] Figure 1 FIG. 1 is a structural schematic diagram of a lifting appliance 20 according to an embodiment of the present application.

[0078] According to some embodiments of the present application, refer to Figure 1 , and further refer to Figures 2 to 9 , Figure 2 FIG. 2 is a partial cross-sectional schematic diagram of a lifting appliance 20 according to an embodiment of the present application, Figures 3 to 6 FIG. 3 is a side view schematic diagram of a lifting appliance 20 according to an embodiment of the present application. Figure 3 FIG. 4 is a side view schematic diagram of a lifting hook 211 according to an embodiment of the present application, Figure 4 FIG. 5 is a side view schematic diagram of a lifting hook 211 according to another embodiment of the present application, Figure 5 FIG. 6 is a side view schematic diagram of a lifting hook 211 according to still another embodiment of the present application, Figure 6 FIG. 7 is a side view schematic diagram of a lifting hook 211 according to still another embodiment of the present application, Figure 7 FIG. 8 is a structural schematic diagram of a hoisted object 30 according to an embodiment of the present application, Figure 8 FIG. 9 is a partial cross-sectional schematic diagram of a hoisted object 30 according to an embodiment of the present application, Figure 9 FIG. 10 is a structural schematic diagram of a hoisting process according to an embodiment of the present application.

[0079] The present application provides a lifting appliance 20, which comprises a lifting hook 211, and the lifting hook 211 comprises a bearing part 2111 for bearing a hoisted object 30, wherein the first surface of the bearing part 2111 for bearing the hoisted object 30 is a plane.

[0080] As shown in the figure, the Z direction in the figure is the thickness direction of the hook 211, the Y direction is the width direction of the first surface of the hook 211, and the X direction is the length direction of the first surface of the hook 211, wherein the Z direction can also be described as the opposite direction of the direction of gravity.

[0081] The bearing part 2111 of the hook 211 is the part directly in contact with the hoisted object 30, and is mainly used to bear and suspend various heavy objects, to ensure that the hoisted object 30 does not fall off during hoisting.

[0082] The material of the hook 211 should be a high-strength, low-density material that can be used to bear the hoisted object 30, for example, the material of the hook 211 can be high-strength steel, aluminum alloy, titanium alloy, magnesium alloy, etc., which has high strength and low density, and has the ability to hoist large hoisted objects 30.

[0083] The first surface of the bearing part 2111 is the surface directly in contact with the hoisted object 30 and bearing its weight during hoisting.

[0084] By designing the first surface as a plane, compared with a curved surface or other shaped surface, the plane design can increase the contact force area between the hook 211 and the hoisted object 30, to alleviate the problem of deformation of the lifting hole 31 of the hoisted object 30 caused by too small contact area between the hook 211 and the hoisted object 30 during hoisting.

[0085] According to some embodiments of the present application, optionally, the hoisted object 30 carried by the hook 211 is an electrical box.

[0086] Since the lifting hole 31 of the large electrical box is prone to deformation during hoisting, the design of the lifting tool 20 solves the problem of easy deformation of the lifting hole 31 of the electrical box.

[0087] According to some embodiments of the present application, optionally, please continue to refer to Figures 1 to 6 , the first surface is a surface perpendicular to the first direction, wherein the first direction is the opposite direction of the direction of gravity (such as the Z direction in Figure 1 ).

[0088] According to the first surface being the surface directly in contact with the hoisted object 30 and bearing its weight during hoisting, it can be determined that the first surface is a surface perpendicular to the first direction (such as the opposite direction of the Z direction in Figure 1 ).

[0089] Optionally, if the hoisting work of the hoisted object 30 is left and right (such as Figure 1The first plane can be a plane perpendicular to the Y direction or a plane perpendicular to the X direction. For example, the hoisting process of the hoisted object 30 is dragging the hoist 20 along the Y direction, the first plane is a plane perpendicular to the Y direction, and the first plane is also arranged as a plane to increase the contact area with the hoisted object 30; for another example, the hoisting process of the hoisted object 30 is dragging the hoist 20 along the X direction, the first plane is a plane perpendicular to the X direction, and the first plane is also arranged as a plane to increase the contact area with the hoisted object 30.

[0090] According to some embodiments of the present application, optionally, the hoist further comprises a main body part 21, and the hook 211 is arranged on the main body part 21.

[0091] The main body part 21 is used to connect with the hook 211, to ensure that the hoist 20 remains stable during hoisting, to prevent the hoisted object 30 from swinging or rotating due to the shift of the center of gravity, and to maintain the balance of the hoisting operation.

[0092] According to some embodiments of the present application, optionally, the hook 211 is protruded on a second plane of the main body part 21, wherein the second plane is a plane, and the second plane is perpendicular to the first plane.

[0093] The second plane is a plane of the main body part 21 perpendicular to the first plane (such as Figure 1 the plane mapped by the main body part 21 along the X direction in the hoist), and arranging the second plane as a plane can prevent the hoisted object 30 from shaking due to the concave-convex of the second plane during hoisting, so that the hoisted object 30 is more stable during hoisting.

[0094] According to some embodiments of the present application, optionally, the hook 211 is integrally formed with the main body part 21.

[0095] Integrally formed means that the hook 211 and the main body part 21 are manufactured as a whole structure through a one-time forming process, rather than being assembled or welded together by multiple separate parts. Since there is no welding point in integrally formed, the hoist 20 after integrally formed usually has higher strength and better durability.

[0096] Through the design of integrally formed, the problem of the hook 211 and the main body part 21 being broken due to the excessive weight of the hoisted object 30 during the process of hanging the hoisted object 30 can be alleviated.

[0097] According to some embodiments of the present application, optionally, the hook 211 further comprises a blocking part 2112, and the blocking part 2112 is arranged at an end of the bearing part 2111 away from the main body part 21.

[0098] The end of the bearing portion 2111 away from the main body portion 21 is a face of the bearing portion perpendicular to the X axis in the opposite direction of the X axis.

[0099] The stop portion 2112 is designed at one end of the bearing portion 2111, which can prevent the hoisting object 30 from sliding out of the open end of the bearing portion 2111, and ensure the safety of the hoisting object 30 during hoisting.

[0100] According to some embodiments of the present application, optionally, the surface of the bearing portion 2111 opposite to the first face is flush with the stop portion 2112. The surface of the bearing portion 2111 opposite to the first face being flush with the stop portion 2112 can be expressed as the bottom of the first face of the bearing portion 2111 being flush with the stop portion 2112. It can also be expressed as the end portion of the stop portion 2112 in the first direction being flush with the end portion of the bearing portion 2111 in the first direction.

[0101] Flush end portion refers to the end portion or edge portion of the stop portion 2112 in the first direction (such as the opposite direction of the Z direction in FIG. Figure 1 or 2) being flush with the end portion of the bearing portion 2111 in the first direction, without any protrusions or recesses, so that the end portions of the two are kept in the same plane.

[0102] The meaning expressed by the bottom of the first face being flush with the end portion is the same, and the bottom of the face opposite to the first face refers to the bottom of the face opposite to the first face, that is, the bottom of the face perpendicular to the opposite direction of the X axis.

[0103] Through the flush design, the hoisting object 30 can be correctly and safely connected with the hook 211 during hoisting.

[0104] According to some embodiments of the present application, optionally, the size of the bearing portion 2111 in the first direction is smaller than the size of the stop portion 2112 in the first direction.

[0105] For reference Figure 5 , the size of the bearing portion 2111 in the first direction (such as the opposite direction of the Z direction in FIG. Figure 5 ) is D5 in FIG. Figure 5 When the size of the bearing portion 2111 in the opposite direction of the Z direction is smaller than the size of the stop portion 2112 in the first direction, the stop portion 2112 can prevent the hoisting object 30 from sliding, being unstable, and other problems during hoisting.

[0106] Optionally, the end of the stop portion 2112 along the first direction can also not be flush with the end of the bearing portion 2111 along the first direction. For example, the end of the stop portion 2112 along the first direction can be higher than the end of the bearing portion 2111 along the first direction. The stop portion 2112 can prevent the lifting object 30 from falling, and can save the material of the lifting hook 211. At this time, the size of the bearing portion 2111 along the first direction can be equal to the size of the stop portion 2112 along the first direction.

[0107] According to some embodiments of the present application, optionally, the size of the bearing portion 2111 along the first direction ranges from 1 cm to 2 cm.

[0108] The size of the bearing portion 2111 along the first direction can be 1 cm, 1.5 cm, or 2 cm.

[0109] According to some embodiments of the present application, optionally, the first surface is printed with a pattern.

[0110] The pattern provided on the first surface can be a thread structure, a concave-convex surface structure, a rubber coating, a tooth-shaped structure, and a viscous coating structure, etc. The present application does not make any limitation on this. For example, the first surface is provided with a thread structure, so that the lifting hole 31 of the lifting object 30 cooperates more firmly with the surface of the first surface, and is more stable during lifting.

[0111] According to some embodiments of the present application, optionally, the lifting appliance further comprises a lifting column 22, and the lifting column 22 is connected with a third surface of the main body portion 21, wherein the third surface is a surface parallel to the first surface.

[0112] The third surface is a projection surface of the main body portion 21 along the Z direction.

[0113] The lifting column 22 can bear the weight of the lifting object 30 and transmit it to the hoisting equipment (such as various types of cranes). The lifting column 22 is used to connect the main body portion 21 and the hoisting machinery.

[0114] According to some embodiments of the present application, optionally, the lifting column 22 is integrally formed with the main body portion 21.

[0115] The integrally formed lifting column 22 and the main body portion 21 means that the lifting column 22 and the main body portion 21 are manufactured as a whole structure through a one-time forming process, rather than being assembled or welded together from multiple separate parts. Since there is no integrally formed welding point, the integrally formed structure has higher strength and better durability. Through the design of integrally forming, the problem of the lifting column 22 and the main body portion 21 being broken due to the excessive weight of the lifting object 30 during the process of hanging the lifting object 30 can be reduced. In addition, since the lifting hook 211, the main body portion 21, and the lifting column 22 are integrally formed in the lifting appliance 20, the materials are consistent. The material of the lifting hook 211 has been described in the above embodiments, and will not be described again here.

[0116] According to some embodiments of the present application, optionally, the distance from the first surface of the bearing part 2111 to the edge of the main body part 21 along the direction opposite to the first direction is in the range of 10 cm to 30 cm.
