Description

Technical Field

[0001] The utility model relates to a hoisting tool, in particular to a box-type transformer shell protection hoisting tool. Background Art

[0002] Photovoltaic modules, also known as solar panels, are the core and most important part of a solar power generation system. Their function is to convert solar energy into electrical energy, either to store it in batteries or to drive loads.

[0003] Photovoltaic modules are prone to tilting and overturning, and are damaged by force during the hoisting and transportation process. Equipment damage causes unnecessary economic losses. In this regard, there are hoisting devices with added guardrails in the prior art. However, the presence of guardrails increases the height of the hoisting tools, which affects loading. The installation and removal of detachable guardrails is time-consuming and labor-intensive. In this regard, the utility model proposes a hoisting tool that does not affect loading and can solve the problem of tilting and overturning of transformers during hoisting. Utility Model Content

[0004] The purpose of the utility model is to provide a box-type transformer shell protection hoisting tool to solve the problems raised in the background technology.

[0005] In order to achieve the above-mentioned utility model purpose, the utility model adopts the following technical solutions:

[0006] A box-type transformer casing protection lifting tool includes a base frame consisting of an inner frame and an outer frame, a bottom support is provided below the base frame, a gap is left between the inner frame and the outer frame, an I-beam is provided on the base frame, the vertical plate of the I-beam is inserted in the gap, and a lifting lug is welded on the top of the I-beam.

[0007] Further technology of the utility model:

[0008] Preferably, the inner frame and the outer frame are connected by bolts, and pads are provided on the bolts to isolate the inner frame and the outer frame.

[0009] Preferably, the height of the vertical plate of the I-beam is higher than the height of the base frame, and the width of the transverse plates at the top and bottom of the I-beam is greater than the width of the gap.

[0010] Preferably, ribs are provided at the connection between the vertical plate and the transverse plate of the I-beam for reinforcement.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides a special lifting tool applicable to the lifting of a box-type transformer shell. Through a double-layer chassis and I-shaped steel, when loading goods, the sinking of the I-shaped steel does not affect the loading. During hoisting, the I-shaped steel is stressed and moves upward, realizing stable limit during the hoisting process of the box-type transformer, thus effectively avoiding the inclination, overturning and stress damage of the transformer shell, and playing a positive role in reducing equipment damage and avoiding unnecessary economic losses.

[0018] In order to make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be further described in detail below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some, rather than all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the protection scope of the present utility model.

[0019] As Figure 1 , the present utility model provides a protective lifting tool for a box-type transformer shell, including a chassis composed of an inner layer frame 1 and an outer frame 2. A bottom support 3 is provided below the chassis. A gap 4 is left between the inner layer frame 1 and the outer frame 2. An I-shaped steel 5 is provided on the chassis. The vertical plate 51 of the I-shaped steel 5 is inserted into the gap 4. A lifting lug 6 is welded to the top of the I-shaped steel 5.

[0020] The inner rack body 1 and the outer frame 2 are connected by bolts 7, and a spacer 8 is provided on the bolts 7 to isolate the inner rack body 1 and the outer frame 2.

[0021] In the above structure, the spacer 8 and the bolts 7 are arranged at the corners of the inner rack body 1 and the outer frame 2, leaving a space for placing the I-beam 5.

[0022] The height of the vertical plate 51 of the I-beam 5 is higher than the height of the chassis, and the widths of the transverse plates 52 at the top and bottom of the I-beam 5 are both greater than the width of the gap 4.

[0023] As Figure 2 , when the lifting tool is in the placed state, the I-beam 5 sags under the influence of gravity. It should be noted that the height of the I-beam 5 is less than the height of the bottom support 3. When the I-beam 5 sags, the bottom of the I-beam 5 does not touch the ground, so that the part of the I-beam 5 exposed above the chassis is less. When loading goods, the I-beam 5 does not affect the loading. As Figure 3 , during lifting, the lifting lug 6 drives the I-beam 5 to move upward under force, forming a "guardrail", realizing the stable limit of the box-type transformer during the lifting process.

[0024] A rib plate 53 is arranged at the connection of the vertical plate 51 and the transverse plate 52 of the I-beam 5 for reinforcement.

[0025] It should be noted that in the material selection of the lifting tool, high-strength steel is used to ensure the stability and durability of the lifting tool when bearing heavy loads. At the same time, in order to prevent the lifting tool from affecting its performance due to rust during use, all metal parts have been subjected to surface treatments such as galvanizing or spraying to improve their corrosion resistance.

[0026] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0027] The above content is only an example and explanation of the structure of the present invention. Those skilled in the art of this technology make various modifications or supplements or use similar methods to replace the specific embodiments described, as long as they do not deviate from the structure of the invention or exceed the scope defined by the claims of the present invention, they should all belong to the protection scope of the present invention.
