[0057] The present application provides a lifting appliance.

[0058] Please refer to Figure 1The lifting appliance 100 is used for hoisting the power distribution cabinet 200. The power distribution cabinet 200 comprises a box body 210 and a plurality of lifting rings 220 connected to the box body 210. Specifically, please refer to Figure 1 and Figure 2 The lifting appliance 100 comprises a top crossbeam 111, a lifting appliance body 110, a plug-in member 120 and a limiting member 130. The top crossbeam 111 is arranged along a first horizontal direction D1. The lifting appliance body 110 has a first connecting position connected to an external hoisting device; the lifting appliance body 110 also has a second connecting position connected to the top crossbeam 111. The first connecting position and the second connecting position are spaced apart along a second horizontal direction D2. The plug-in member 120 is arranged along the second horizontal direction D2 and connected to the top crossbeam 111 at one end. The number of the plug-in member 120 is at least two, and the at least two plug-in members 120 are arranged spaced apart along the first horizontal direction D1, and the second horizontal direction D2 is inclined or perpendicular to the first horizontal direction D1. The plug-in member 120 is used for connecting with the lifting ring 220. The limiting member 130 is detachably connected to the plug-in member 120. It should be noted that, in the state that the plug-in member 120 is connected to the lifting ring 220, at least one lifting ring 220 is located between the lifting appliance body 110 and the limiting member 130, so as to avoid the plug-in member 120 from being separated from the lifting ring 220. Moreover, along the second horizontal direction D2, the first connecting position is closer to the free end of the plug-in member 120 than the second connecting position.

[0059] According to the lifting appliance 100 of the utility model, in the process that the external hoisting device hoists the whole formed by the lifting appliance 100 and the power distribution cabinet 200, the power distribution cabinet 200 will not be offset relative to the lifting appliance 100 basically, and the limiting member 130 can further prevent the power distribution cabinet 200 from slipping off relative to the lifting appliance 100, thereby improving the safety of hoisting the power distribution cabinet 200.

[0060] It should be noted that the free end of the plug-in member 120 is different from the one end connected to the top crossbeam 111. Preferably, the first horizontal direction D1 is perpendicular to the second horizontal direction D2. Figure 1 In the embodiment, the number of the lifting rings 220 of the power distribution cabinet 200 is four, and the lifting rings 220 are connected to the top of the box body 210. The lifting ring 220 has a hoisting hole, and the axis of the hoisting hole extends along the second horizontal direction D2. Along the second horizontal direction D2, the number of the lifting rings 220 is two and spaced apart from each other. The two lifting rings 220 spaced apart along the second horizontal direction D2 form a group, that is, the power distribution cabinet 200 has two groups of lifting rings 220, and the two groups of lifting rings 220 are spaced apart along the first horizontal direction D1.

[0061] Please continue to refer to Figure 1 and Figure 2The hoist body 110 comprises a stand column 112. The stand column 112 is arranged along the vertical direction DH, and the stand column 112 is connected to the top crossbeam 111. Preferably, the top crossbeam 111 and the stand column 112 are made of angle iron. Further, the stand column 112 is connected to the middle part of the top crossbeam 111. Specifically, the stand column 112 has the aforementioned second connecting position, which can be configured as a notch 113 adapted to the top crossbeam 111. The notch 113 is connected to the top surface and at least one side surface of the top crossbeam 111. For example Figure 1 The notch 113 is connected to the side surface of the top crossbeam 111 away from the power distribution cabinet 200.

[0062] The hoist body 110 further comprises a hoisting plate 114 arranged along the second horizontal direction D2, and the hoisting plate 114 is arranged above the top crossbeam 111 and connected to the stand column 112. It should be noted that the free end of the hoisting plate 114 is arranged towards the power distribution cabinet 200. The hoisting plate 114 is spaced apart from the top crossbeam 111 along the vertical direction DH. Further, the hoisting plate 114 has a plurality of adjusting holes 115 arranged through the thickness of the hoisting plate 114, and the plurality of adjusting holes 115 are spaced apart along the second horizontal direction D2. It can be understood that the adjusting holes 115 can be directly connected to the external hoisting equipment. Alternatively, as shown in Figure 1 The hoist body 110 further comprises an adjusting member 116 detachably connected to the adjusting hole 115. According to the distribution of the center of gravity of the whole formed by the power distribution cabinet 200 and the hoist, the adjusting member 116 is connected to different adjusting holes 115 (or the external hoisting equipment is connected to different adjusting holes 115), so that the external hoisting equipment is connected to the corresponding adjusting member 116. In other words, the adjusting member 116 has the aforementioned first connecting position, and when the plug-in member 120 is connected to the lifting eye 220, the whole formed by the hoist 100 and the power distribution cabinet 200 has a center of gravity, and the line connecting the center of gravity and the connecting position extends along the vertical direction DH. Of course, in actual use, the line connecting the center of gravity and the connecting position has a certain inclination relative to the vertical direction DH, which does not affect the use, and the limiting member 130 can effectively prevent the power distribution cabinet 200 from slipping relative to the hoist 100.

[0063] Preferably, the axis of the adjusting hole 115 extends along the first horizontal direction D1, and the adjusting member 116 is pivotally connected to the hoisting plate 114 about the axis of the adjusting hole 115. Alternatively, the adjusting member 116 is pivotally connected to the hoisting plate 114 about the axis extending along the first horizontal direction D1, so as to facilitate the connection of the adjusting member 116 and the external hoisting equipment.

[0064] Please refer to Figure 2 and Figure 3 The plug-in member 120 has at least one mounting hole 121 penetrating through itself, and the limiting member 130 penetrates through the mounting hole 121 and protrudes outwardly from the plug-in member 120. For exampleFigure 2 And Figure 3 In the embodiment, the inserting member 120 has a mounting hole 121 passing through the inserting member 120. Further, the inserting member 120 comprises a fixing part 122 and an inserting part 123. The fixing part 122 is used to connect to the hoist body 110, specifically, to the top cross beam 111. The inserting part 123 is connected to the fixing part 122, and the inserting part 123 is used to pass through the aforementioned lifting ring 220. The inserting part 123 is configured as a columnar structure, and the inserting part 123 has a first end 124 close to the hoist body 110 and a second end 125 away from the hoist body 110. The outer diameter of the inserting part 123 decreases from the first end 124 to the second end 125. In this way, the inserting member 120 is facilitated to pass through the lifting ring 220. The limiting member 130 can be a fast dismounting pin (see Figure 3 ) in the market. In an embodiment not shown, the limiting member 130 can be configured as a cylindrical structure, and the size of the limiting member 130 along the first horizontal direction D1 is greater than the size of the lifting ring 220. The number of the limiting member 130 is at least two (each corresponding to the inserting member 120) and connected to the inserting member. For example Figure 2 In the embodiment, the number of the limiting member 130 is two and connected to different inserting members 120. In order to improve the limiting effect and further ensure that the power distribution cabinet 200 will not slip relative to the hoist 100, in an embodiment not shown, each lifting ring 220 is provided with a limiting member 130 away from one side of the hoist body 110 along the second horizontal direction D2 in the state that the inserting member 120 is connected to the lifting ring 220.

[0065] It should be noted that, in view of the stability and safety of the overall structure of the hoist 100, the overall structure is preferably welded. For example, the top cross beam 111 is welded to the stand column 112; the lifting plate 114 is welded to the stand column 112; and the inserting member 120 is welded to the top cross beam 111.

[0066] According to the hoist of the utility model, according to the weight distribution of the power distribution cabinet, the connecting position of the external lifting equipment and the hoist can be adjusted, the line connecting the first connecting position and the aforementioned gravity center position is made to extend along the vertical direction as much as possible, so that the power distribution cabinet is prevented from tilting during lifting. The adjusting member and the lifting plate are easy to quickly disassemble and replace. The overall structure of the hoist is lightweight, the power distribution cabinet can be quickly lifted, and the overall size of the hoist is not large, which is convenient for transportation and storage.
