[0030] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.
[0031] The specific implementation of the utility model described herein is only used to explain the purpose of the utility model, and cannot be understood as a limitation of the utility model in any way. Under the guidance of the utility model, technicians can conceive of any possible deformation based on the utility model, which should be regarded as belonging to the scope of the utility model. It should be noted that when an element is referred to as "arranged on" another element, it can be directly on the other element or there can also be a central element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a central element at the same time. The terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a mechanical connection or an electrical connection, or it can be the internal communication of two elements, it can be directly connected, or it can be indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation method.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0033] like Figures 1 to 4 As shown, the utility model provides a simple lifting device 100 for a box-type transformer, including a skeleton 1 located above the box-type transformer along the lifting width direction of the box-type transformer 3 (the axial direction of the lifting axis or the lifting hole at the bottom of the box-type transformer 3, the lifting axis or the lifting hole at the bottom of the box-type transformer is the prior art) during lifting, and limiting rings 2 are respectively arranged at both ends of the skeleton 1, and limiting holes 21 for passing the lifting rope 4 are respectively arranged on each limiting ring 2, and the center distance dimension of the two limiting holes 21 is larger than the lifting width dimension of the box-type transformer 3.
[0034] The limiting ring 2 does not bear the lifting gravity, and the lifting rope can slide in the limiting ring. The limiting ring 2 mainly limits the position of the lifting rope passing therethrough so that it will not deviate or even fall off.
[0035] like Figure 5 , Figure 6 As shown, the simple lifting device 100 for the box-type transformer of the utility model is generally used in pairs and is arranged at intervals along the length direction of the box-type transformer. Two lifting shafts 31 (existing technology) are generally arranged on one side of the box-type transformer 3 in the width direction, and the lifting rope 4 can be detachably connected to the lifting shaft 31, forming a triangular lifting method on one side. The utility model is placed above the box-type transformer 3 along the lifting width direction of the box-type transformer. The center distance of the limiting holes of the limiting rings at both ends of the skeleton 1 is larger than the lifting width dimension of the box-type transformer 3. The skeleton and the limiting rings support the lifting ropes 4 on both sides, so that the distance between the lifting ropes on both sides is limited and cannot be reduced. In this way, there is a suitable distance between the lifting ropes and the outermost edge of the box transformer shell to protect the shell from being strangled.
[0036] The center distance of the limiting holes of the limiting rings 2 at both ends of the skeleton 1 is larger than the lifting width of the box-type transformer 3, but should not be too large. To ensure the stability of the lifting process, the angle α between the lifting ropes on both sides passing through the limiting rings at both ends of the skeleton is not greater than 60°.
[0037] The dimensions of the frame 1 and the limit ring 2 are determined according to the specifications of the box-type transformer 3 to be actually hoisted. This hoist is a special type and is only used once when unloading the truck after delivery to the site. It does not need to adjust the dimensions or configure other hoists, such as shackles.
[0038] The utility model can be used when unloading containers in remote areas where recycling is unlikely to be achieved. As a disposable lifting device, it is more economical and convenient for transportation.
[0039] In the simple lifting device for the box-type transformer of the utility model, the frame and the limiting ring support the lifting ropes on both sides of the box-type transformer to ensure that the lifting ropes will not contact the top of the box-type transformer (the roof cover of the box-type transformer) to avoid the box-type transformer being strangled by the lifting ropes; the limiting ring is used to limit the sliding of the lifting rope to prevent the lifting rope from falling off; the utility model determines the length specification according to the actual lifting of the box-type transformer and has strong adaptability; the utility model has a simple structure and a low cost, thereby reducing cost expenditure.
[0040] Furthermore, in order to reduce the wear of the suspension rope, a protective cover can be provided on the side wall of the limiting hole 21 .
[0041] The protective cover can be made of rubber, and the protective cover is bonded into the limiting hole 21 .
[0042] Further, if Figure 1 , Figure 2 , Figure 3As shown, the limiting ring 2 adopts a circular ring structure. It can also adopt other shapes that are easy to manufacture.
[0043] Furthermore, the limiting ring 2 is made of round steel or steel plate, and can also be made of other materials with a certain rigidity to avoid being strangled or deformed by the suspension rope 4.
[0044] Furthermore, the frame 1 is made of angle steel, channel steel or I-beam.
[0045] Furthermore, the limiting ring 2 can be fixedly connected to both ends of the frame (such as Figure 4 Shown), it is also possible to be removably connected to both ends of the skeleton 1.
[0046] When fixedly connected, the limiting rings 2 can be welded to both ends of the frame 1 .
[0047] When the connection is detachable, a connecting screw is arranged on the limiting ring 2, and connecting nuts are arranged at both ends of the frame 1. The limiting ring 2 is connected to both ends of the frame 1 through the connecting bolts and the connecting nuts.
[0048] As described above, the simple lifting device for box-type transformer of the utility model has the following beneficial effects:
[0049] In the simple lifting device for the box-type transformer of the utility model, the frame and the limiting ring support the lifting ropes on both sides of the box-type transformer to ensure that the lifting ropes will not contact the top of the box-type transformer (the roof cover of the box-type transformer) to avoid the box-type transformer being strangled by the lifting ropes; the limiting ring is used to limit the sliding of the lifting rope to prevent the lifting rope from falling off; the utility model determines the length specification according to the actual lifting of the box-type transformer and has strong adaptability; the utility model has a simple structure and a low cost, thereby reducing cost expenditure.
[0050] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
