It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0029] like Figures 1 to 6 As shown, an embodiment of the present application provides a lifting beam with adjustable angle, comprising:

[0030] Beam 10;

[0031] A plurality of first lifting ears 20, wherein the first lifting ears 20 are arranged on one side of the beam body 10 and are used to cooperate with the hook of the door crane;

[0032] A plurality of second lifting ears 30, wherein the second lifting ears 30 are arranged on a side of the beam body 10 away from the first lifting ears 20, and are used for lifting objects, and the arrangement directions of the plurality of second lifting ears 30 are not completely the same;

[0033] The second lifting eye 30 includes a first sub-lifting eye 31 and a second sub-lifting eye 32 . The first sub-lifting eye 31 extends along the length direction of the beam body 10 , and the second sub-lifting eye 32 extends along the width direction of the beam body 10 .

[0034] This embodiment provides a lifting beam that can achieve angle adjustment, and different lifting ears are set on both sides of the angle-adjustable lifting beam, wherein the first lifting ear 20 is used to be installed in cooperation with the hook on the door crane, and the second lifting ear 30 is used to cooperate with the lifting object to achieve the lifting of the lifting object. A plurality of second lifting ears 30 with different directions are set, and the lifting of objects in different directions can be achieved through the cooperation between different second lifting ears 30, so that the provided lifting beam can meet the different angle requirements of the relevant lifting objects during use.

[0035] Figure 1The structural schematic diagram of the adjustable angle hoisting beam is provided in the figure, in which only the positions and divisions of the first lifting lug 20 and the second lifting lug 30 on the hoisting beam are shown, and the hoisting beam body 10 is schematically represented by a rectangular parallelepiped structure, which is not consistent with the actual structure of the beam body 10. The hoisting beam is composed of the beam body 10 and the lifting lugs arranged on both sides of the beam body 10. The first lifting lug 20 is arranged above the beam body 10. There are multiple first lifting lugs 20, which are used to cooperate with the hook on the door crane for installation. Therefore, the number and bearing capacity of the first lifting lug 20 are related to the bearing capacity of the door crane and the position of the hook on the door crane. The positions, setting numbers and bearing capacities of multiple first lifting lugs 20 can be changed according to different door cranes. The second lifting lug 30 is arranged below the beam body 10. There are also multiple second lifting lugs 30, which are used to hoist objects, and the bearing capacity and setting direction of each second lifting lug 30 are not completely the same. The distribution of the bearing capacity of different second lifting lugs 30 and the distribution of setting directions can be carried out according to different usage requirements.

[0036] For example Figure 1 A plurality of second lifting ears 30 arranged below the beam body 10 are provided. The second lifting ears 30 form two arrangement modes, and each mode is provided with a plurality of second lifting ears 30. Different second lifting ears 30 can be used in combination to form different directions and angles, and in this way, the lifting objects at different angles can be satisfied. In this embodiment, the second lifting ears 30 are divided into two types, namely, the first sub-lifting ear 31 and the second sub-lifting ear 32. The beam body 10 is a structure similar to a rectangular parallelepiped. The first sub-lifting ear 31 extends along the length direction of the beam body 10, and the second sub-lifting ear 32 extends along the width direction of the beam body 10. The form of a plurality of second lifting ears 30 is formed by different setting directions, and the first sub-lifting ear 31 and the second sub-lifting ear 32 are provided in plurality, which can be selected and matched according to actual needs. The first sub-lifting ear 31 and the second sub-lifting ear 32 cooperate with each other to form a variety of different lifting angles, which can fully meet the lifting needs.

[0037] Optionally, the beam body 10 includes two first side plates 11 arranged opposite to each other, the first sub-hanging lug 31 is installed on each of the first side plates 11, and the second sub-hanging lug 32 is installed between the two first side plates 11.

[0038] The distance between the two first side plates 11 at the location of the first sub-hanging lug 31 is greater than the distance between the two first side plates 11 at the location of the second sub-hanging lug 32 .

[0039] like Figure 2As shown, the beam body 10 in this embodiment includes two first side plates 11 arranged opposite to each other, and the first sub-hanging ears 31 are installed on the first side plates 11. In order to achieve balanced force during the use of the lifting beam, the first sub-hanging ears 31 are installed on the opposite first side plates 11 in this embodiment to form a symmetrical structure, and the symmetrical first sub-hanging ears 31 are used simultaneously when in use. Therefore, sufficient space is required between the two opposite first sub-hanging ears 31 for installing the lifting tools to meet the lifting use. In addition, the second sub-hanging ears 32 are installed between the opposite first side plates 11, and the formed second sub-hanging ears 32 are perpendicular to the first sub-hanging ears 31. The corresponding second sub-hanging ears 32 can be used alone or in conjunction with other hanging ears. The space between the two first side plates 11 required at the position of the second sub-hanging ears 32 is relatively small. Therefore, in this embodiment, the opposite first side plates 11 are preferably set to a structure with wide ends and narrow middle, that is, at the position of the first sub-hanging ears 31, the distance between the two first side plates 11 is large, providing sufficient installation space for the use of the first sub-hanging ears 31.

[0040] This embodiment preferably adopts Figure 6 The first side plate 11 shown in the figure is a trapezoidal structure, which includes a first mounting portion 113 and a second mounting portion 111. The first mounting portion 113 and the second mounting portion 111 are parallel to each other and connected in the middle by a connecting portion 112. The connecting portion 112 is an inclined portion. The first mounting portion 113 is used to mount the first sub-hanging ear 31, and the second mounting portion 111 is used to mount the second sub-hanging ear 32, forming a structure as shown in FIG. Figure 2 In the form shown, in addition to meeting the installation space requirements of the first sub-lifting ear 31, the first side panel 11 structure reduces the material usage of the first side panel 11 through the narrower installation position of the second sub-lifting ear 32, so that the first side panel 11 meets the installation space requirements of the first sub-lifting ear 31 with less material, and the weight of the corresponding lifting beam is also smaller, saving materials and meeting the lifting requirements.

[0041] Optionally, the beam body 10 further includes two oppositely disposed top plates 14 and two oppositely disposed second side plates 13 , the two top plates 14 are respectively connected to the two first side plates 11 , and the two second side plates 13 are respectively connected to the two first side plates 11 , to form a box-type structure.

[0042] In this embodiment, the top plate 14 and the second side plate 13 are connected to the first side plate 11 to form a box-type beam body 10 structure. The top plate 14 is divided into the upper and lower sides of the beam body 10 (with Figure 1The second side plate 13 is arranged on the left and right sides of the beam body 10 and is arranged in a rectangular shape. Through the trapezoidal first side plate 11 structure, the size of the corresponding top plate 14 is also reduced, and the weight of the overall hoisting beam is reduced.

[0043] Optionally, a reinforcing rib plate 12 is further included, and the reinforcing rib plate 12 is disposed between the two first side plates 11 and connected to the top plate 14 and the second side plate 13 .

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, a reinforcing rib plate 12 is provided inside the beam body 10. The reinforcing rib plate 12 is in a vertical form, parallel to the surface where the first side plate is located, and connected to the top plate 14 and the second side plate 13. The supporting capacity of part of the first lifting ear 20 and part of the second lifting ear 30 extending along the width direction of the lifting beam is strengthened by the reinforcing rib plate 12, so that the provided lifting ear structure meets the required bearing capacity requirements.

[0045] Furthermore, the second lifting lugs 30 are distributed along the length direction of the beam body 10, the first sub-lifting lugs 31 are arranged near the end of the beam body 10, and the second sub-lifting lugs 32 are arranged near the middle of the beam body 10;

[0046] The bearing capacity of the first sub-hanging eye 31 is smaller than the bearing capacity of the second sub-hanging eye 32 .

[0047] refer to Figure 2 and Figure 3 As shown, the arrangement and division of each lifting ear on the lifting beam in this embodiment are given, wherein the second lifting ear 30 is mainly to meet the lifting requirements of lifting objects at different angles, and is arranged at intervals along the length of the beam body 10, wherein the first sub-lifting ear 31 is a structure extending along the length direction of the beam body 10, each first sub-lifting ear 31 is arranged on the first side plate 11 of the beam body 10, and each first sub-lifting ear 31 is symmetrically installed on the beam body 10, so that the first sub-lifting ear 31 is symmetrically arranged on the relatively arranged first side plates 11, and the lifting beam ensures balanced force when in use; each second sub-lifting ear 32 is arranged along the width direction of the beam body 10, and is arranged between the two first side plates 11, and is connected to the two first side plates 11. Therefore, in this embodiment, the bearing capacity of the first sub-lifting ear 31 is preferably set to be smaller than the bearing capacity of the second sub-lifting ear 32, and the second sub-lifting ear 32 is arranged in the middle position of the beam body 10, and the first sub-lifting ear 31 is arranged at both ends of the beam body 10, so that the lifting ear in the middle position has a greater bearing capacity.

[0048] Optionally, the first sub-hanging ears 31 are symmetrically installed on the beam body 10 along the reinforcing rib plate 12 .

[0049] refer to Figure 1 and Figure 2 As shown, in this embodiment, a first sub-hanging ear 31 is set at the end of the beam body 10. Since the first sub-hanging ear 31 extends along the length direction of the beam body 10 and is connected to the first side plate 11, in order to achieve force balance during the use of the lifting beam, the first sub-hanging ear 31 is set to a symmetrical structure, and the axis of symmetry is the surface where the reinforcing rib plate 12 is located, that is, the same first sub-hanging ear 31 is set on the opposite first side plates 11. When in use, the symmetrical first sub-hanging ears 31 are used at the same time. Therefore, in this embodiment, the bearing capacity of the first sub-hanging ear 31 is preferably set to be smaller than the bearing capacity of the second sub-hanging ear 32. When the two symmetrical first sub-hanging ears 31 are used at the same time, the bearing capacity is the sum of the bearing capacities of the two first sub-hanging ears 31. This setting form can ensure that the lifting beam provided by this embodiment has more bearing capacity options, and the bearing capacity is within the required range, and there will be no waste caused by excessive bearing capacity.

[0050] Optionally, the second lifting eye 30 includes four first sub-lifting eyes 31 and four second sub-lifting eyes 32 .

[0051] refer to Figures 1 to 3 As shown, in this embodiment, eight second lifting ears 30 are arranged below the beam body 10, including four first sub-lifting ears 31 and four second sub-lifting ears 32. The four first sub-lifting ears 31 are arranged in pairs at positions close to the end of the beam body 10. Preferably, the first sub-lifting ears 31 are arranged as a lifting ear structure with a bearing capacity of 45 tons, and two symmetrical first sub-lifting ears 31 form a lifting ear structure with a bearing capacity of 90 tons; the four second sub-lifting ears 32 are arranged in sequence in the middle position of the beam body 10, and the spacing between adjacent second sub-lifting ears 32 is determined according to actual needs. In this embodiment, two second sub-lifting ears 32 with a bearing capacity of 50 tons and two second sub-lifting ears 32 with a bearing capacity of 70 tons are preferably arranged. Therefore, the bearing capacity of the second lifting ears 30 arranged below the beam body 10 can be used for lifting objects of 50 tons, 70 tons, 90 tons, etc., thereby realizing the lifting of different objects.

[0052] The above embodiment specifically describes the specific setting form of the second lifting lug 30 disposed below the beam body 10. The second lifting lug 30 with different directions and different bearing capacities can be used to lift different objects, and the angle of the lifting device can be adjusted when lifting the objects. A first lifting lug 20 is also disposed above the beam body 10. The first lifting lug 20 is used to connect to the hook on the door crane. Therefore, the setting form of the first lifting lug 20 can match different door crane structures used. In this embodiment, five first lifting lugs 20 are preferably disposed above the beam body 10, wherein the setting directions of the plurality of second lifting lugs 30 are not completely the same.

[0053] In this embodiment, the setting form of the first lifting ear 20 is the same as that of the second lifting ear 30, and it is also divided into a third sub-lifting ear 21 extending along the length direction of the beam body 10 and a fourth sub-lifting ear 22 extending along the width direction of the beam body 10. The third sub-lifting ear 21 is set in the same way as the first sub-lifting ear 31, both are installed on the first side plate 11, and form a symmetrical form along the reinforcing rib plate 12. The two symmetrically arranged lifting ears can provide double the lifting bearing capacity when used simultaneously. The fourth sub-lifting ear 22 is set in the same way as the second sub-lifting ear 32, and is set in a form perpendicular to the first sub-lifting ear 31, and the bearing capacity of the third sub-lifting ear 21 is less than that of the fourth sub-lifting ear 22.

[0054] In this embodiment, for the convenience of processing, the first sub-hanging ear 31 and the third sub-hanging ear 21, which are both arranged on the first side plate 11, are arranged on the same straight line to form a Figure 3 and Figure 5 In the structure shown, the first sub-hanging ear 31 and the third sub-hanging ear 21 are arranged on the upper and lower surfaces of the beam body 10 and can be formed from the same piece of material, making preparation and installation more convenient.

[0055] In addition, the ear structure required in this embodiment includes three parts, a connecting part 112 arranged in the middle, and reinforcing parts arranged on both sides of the connecting part 112. The connecting part 112 is relatively long to achieve fixed connection with the first side plate 11 and the reinforcing rib plate 12, and the reinforcing parts on both sides are attached to the connecting part 112 and used as reinforcing ribs.

The area of ​​the connecting portion 112 on each hanging ear is different according to the different bearing capacities of the hanging ears. Figure 5 It is a side view of the fourth middle lifting lug 22. The fourth lifting lug 22 is a lifting lug with a bearing capacity of 70 tons. The reinforcement portion is extended to the inside of the beam body 10, so that the lifting lug with large bearing capacity has a larger reinforcement portion structure. Figure 3 The second sub-lifting lug 32 arranged at the lower side of the beam body 10 is divided into different bearing capacities, wherein the reinforcement areas of the lifting lug with a bearing capacity of 50 tons and the lifting lug with a bearing capacity of 70 tons are different.
