[0033] In the related art, there is a technical problem that the steel plate 200 is difficult to separate from the lifting appliance 100 when lifting the steel plate 200. The present application provides a lifting appliance 100 and a lifting device, which can at least solve the technical problem that the steel plate 200 is difficult to separate from the lifting appliance 100 when lifting the steel plate 200.

[0034] The present application will be described below in conjunction with the drawings and specific embodiments:

[0035] The lifting appliance 100 comprises a lifting frame 110 and at least two supporting ropes 120. The plurality of supporting ropes 120 are arranged at intervals along the first direction, the supporting ropes 120 are located below the lifting frame 110, both ends of the supporting ropes 120 are connected to the lifting frame 110, and at least one end of the supporting ropes 120 is detachably connected to the lifting frame 110. A limiting cavity for limiting the hoisted object is formed between the supporting ropes 120 and the lifting frame 110.

[0036] It should be noted that the lifting appliance 100 can hoist the hoisted object such as the steel plate 200 and the reinforcing bar, and the specific type of the hoisted object is not limited in the present application. The hoisted object is taken as the steel plate 200 in the following description.

[0037] At least one end of the supporting rope 120 is detachably connected to the lifting frame 110. It can be that one end of the supporting rope 120 is detachably connected to the lifting frame 110, and the other end is not detachably connected to the lifting frame 110. It can also be that both ends of the supporting rope 120 are detachably connected to the lifting frame 110. The detachable connection between the supporting rope 120 and the lifting frame 110 can be various, such as clamping, inserting, bolt connection, binding connection, etc., which is not limited in the present application.

[0038] When using the lifting appliance 100 of the present application, the length direction of the steel plate 200 is parallel to the first direction, and the plurality of supporting ropes 120 are arranged at intervals along the first direction to uniformly support each part of the length direction of the steel plate 200, which helps to reduce the deformation of the steel plate 200 during lifting and avoid the upwarping of both ends of the steel plate 200.

[0039] The support rope 120 is arranged below the lifting frame 110. When both ends of the support rope 120 are connected with the lifting frame 110, the support rope 120 and the lifting frame 110 enclose a ring-shaped hole, that is, a limiting cavity. When the steel plate 200 is lifted, the steel plate 200 is located in the limiting cavity, that is, the steel plate 200 is located above the support rope 120 and below the lifting frame 110, that is, between the lifting frame 110 and the support rope 120. The support rope 120 supports the steel plate 200, and the lifting frame 110 pulls the support rope 120.

[0040] In use of the lifting device 100, the lifting frame 110 is connected with a lifting mechanism of a lifting device such as a crane or a truck crane. The lifting mechanism applies force to the lifting frame 110, so that the lifting frame 110 moves, and the lifting frame 110 drives the support rope 120 located below the lifting frame 110 to move, thereby driving the steel plate 200 located on the support rope 120 to move.

[0041] In this way, after the steel plate 200 is lifted to a designated position, a plurality of pads are arranged on the ground, and then the steel plate 200 is lowered onto the pads, and the end of the support rope 120 that is detachably connected with the lifting frame 110 is separated, and then the lifting device 100 is lifted, so that the lifting device 100 and the steel plate 200 are separated. The separation of the lifting device 100 and the steel plate 200 is more convenient, avoids the cumbersome process of using a forklift or a crowbar and the safety risks that may be caused, improves the separation efficiency, and ensures the safety performance of the separation. In addition, in this way, the lifting frame 110 is not located below the steel plate 200, so it does not interfere with the contact between the steel plate 200 and the pads, and thus the influence of the lifting frame 110 on the separation of the steel plate 200 is not considered. Therefore, the two ends of the lifted steel plate 200 can or can not extend out of the lifting frame 110, so that the lifting device 100 can lift steel plates 200 of various lengths, and the range of adaptation is wider.

[0042] In some embodiments, as shown in FIG. 1B, three support ropes 120 are arranged. Figure 1

[0043] In some embodiments, the support rope 120 is arranged along a second direction, and the second direction is perpendicular to the first direction. In use of the lifting device 100, the width direction of the steel plate 200 is parallel to the second direction. In this way, the support ropes 120 are parallel, and the length direction of each support rope 120 is arranged along the second direction. The support ropes 120 support various parts of the width direction of the steel plate 200, which helps to ensure the stability of the steel plate 200 during lifting and reduces the risk of the steel plate 200 sliding and falling.

[0044] ​In some embodiments, the lifting frame 110 is provided with a connecting protrusion 111, and the two ends of the support rope 120 are connected with the connecting protrusion 111. It should be noted that one support rope 120 is provided with two connecting protrusions 111, the two connecting protrusions 111 are oppositely arranged along the second direction, and are arranged on the two sides of the lifting frame 110 along the second direction respectively, and the two ends of the support rope 120 are connected to the two connecting protrusions 111 respectively. The support rope 120 and the connecting protrusion 111 can be connected by clamping, binding and the like.

[0045] In some embodiments, the two ends of the support rope 120 are provided with a hanging hole 120a, and the two ends of the support rope 120 are sleeved outside the connecting protrusion 111 through the hanging hole 120a. After such design, when it is needed to separate the support rope 120 and the connecting protrusion 111, the support rope 120 can be taken off from the connecting protrusion 111, and when it is needed to connect the support rope 120 and the connecting protrusion 111, the support rope 120 can be sleeved outside the connecting protrusion 111 through the hanging hole 120a, the connection and separation between the support rope 120 and the connecting protrusion 111 is relatively convenient, the operator does not need to use additional tools or complex operation to fix the support rope 120, which helps to improve the lifting efficiency.

[0046] In some embodiments, the connecting protrusion 111 is in a cylindrical shape.

[0047] In some embodiments, the support rope 120 is a chain, and the chain is formed by a plurality of small rings connected in sequence. Such design enables the operator to adjust the actual working length of the chain between the two connecting protrusions 111 by selecting different small rings to be sleeved on the connecting protrusions 111, so that the working length of the chain can be adaptively adjusted according to the width of the steel plate 200 and the like, which facilitates the use of the operator.

[0048] In some embodiments, the lifting frame 110 includes a plurality of cross beams 112 and a plurality of longitudinal beams 113. The plurality of cross beams 112 are arranged at intervals along the first direction; the plurality of longitudinal beams 113 are arranged at intervals along the second direction, the second direction is perpendicular to the first direction, and each longitudinal beam 113 is connected with each cross beam 112. The cross beam 112 is parallel to the second direction, the longitudinal beam 113 is parallel to the first direction, and the cross beam 112 and the longitudinal beam 113 are perpendicular. Each longitudinal beam 113 is connected with each cross beam 112, and the longitudinal beam 113 and the cross beam 112 can be connected by welding, bolt connection, clamping and the like. The lifting frame 110 is connected by the plurality of cross beams 112 and the plurality of longitudinal beams 113, and the plurality of cross beams 112 and the plurality of longitudinal beams 113 are arranged at intervals, which helps to reduce the weight of the lifting frame 110.

[0049] In some embodiments, the connecting protrusion 111 is arranged on the longitudinal beam 113.

[0050] In some embodiments, the lifting frame 110 comprises 4 cross beams 112 and 3 longitudinal beams 113

[0051] In some embodiments, the lifting device 100 further comprises lifting lugs 130 connected to the lifting frame 110. The lifting lugs 130 can be used to connect with the hook, rope, shackle and other components of the lifting mechanism, and the arrangement of the lifting lugs 130 can facilitate the connection of the lifting device 100 with the lifting mechanism.

[0052] In some embodiments, at least four lifting lugs 130 are arranged in an array, which can make the stress on the lifting frame 110 uniform, reduce the risk of shaking or tilting caused by excessive stress on a single point, and enhance the stability and safety of the lifting operation.

[0053] In some embodiments, the lifting device 100 further comprises lifting ropes 140 and a hanging ring 150. The number of lifting ropes 140 is consistent with the number of lifting lugs 130, and each lifting rope 140 is connected to a corresponding lifting lug 130 at one end. The hanging ring 150 is connected to the other end of each lifting rope 140, and the hanging ring 150 has a connecting through hole 150a for connecting with the hook 400 of the lifting mechanism. That is, the lifting ropes 140 and the lifting lugs 130 are arranged one-to-one, each lifting lug 130 is connected to one lifting rope 140, and the plurality of lifting ropes 140 are connected to the hanging ring 150. The lifting ropes 140 can be lifting belts, steel wires, etc., which are not limited in the present application. After such design, the lifting device 100 is equipped with lifting ropes 140 and a hanging ring 150, and when the steel plate 200 needs to be lifted, the operator only needs to set the hanging ring 150 on the hook 400 of the lifting mechanism, and the connection between the lifting device 100 and the lifting mechanism can be quickly completed, thereby improving the lifting efficiency.

[0054] In some embodiments, four lifting lugs 130 and four lifting ropes 140 are provided.

[0055] In some embodiments, the lifting device 100 further comprises shackles 160, and the lifting ropes 140 and the lifting lugs 130, as well as the hanging ring 150 and the lifting ropes 140, are connected through the shackles 160. The structure of the shackles 160 is known to those skilled in the art, and will not be described here. The shackles 160 allow the lifting ropes 140 and the lifting lugs 130, as well as the hanging ring 150 and the lifting ropes 140, to be quickly and easily connected and separated, which helps to improve the operation efficiency of the lifting operation and facilitates the replacement of damaged lifting ropes 140 by the operator.
