Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an air box of an inflatable cabinet which is convenient for hoisting. Background Art

[0002] During the production or shipment of the air box of the inflatable cabinet, it needs to be hoisted and transferred to the next working station. Generally, it needs to be hoisted by an electric hoist and then transferred. Therefore, it is very necessary to design a hoisting hole for the air box. Most of the existing hoisting holes or lifting rings are directly welded to the top plate. However, for the air box with more than one unit, its overall mass increases by multiples compared with the air box of one unit, but the wall thickness of the materials used for the air box and other structures have not changed. For this reason, the air box with more than one unit is more likely to deform. For this reason, the manufacturer generally installs reinforcing ribs on the top of the large air box to prevent the air box from deforming after inflation; and for the convenience of hoisting, the lifting ring is generally installed on the reinforcing rib instead of directly on the top plate of the large air box, so as to avoid deformation during hoisting due to the pulling of the top plate by the lifting ring. However, this method will make the whole reinforcing rib act as a strengthened whole and pull the whole top plate, and will also cause uneven local stress on the top plate, resulting in serious deformation of the air box. Content of the Utility Model

[0003] To achieve the above object, the utility model provides an air box of an inflatable cabinet which is convenient for hoisting, including a box body and a plurality of reinforcing ribs. The box body includes a top plate and side plates on both sides. The tops of the two side plates protrude from the plane where the top plate is located. A plurality of corresponding hoisting holes are arranged on the regions where the two side plates protrude from the top plate. All the reinforcing ribs are respectively arranged on the corresponding regions of the top plate where all the hoisting holes are located. The two ends of all the reinforcing ribs are respectively welded and fixed to the two side plates.

[0004] In some possible implementation manners, all the reinforcing ribs are in a U shape, and the side where the opening of the reinforcing rib is located is welded and fixed to the top plate to form a hoisting channel.

[0005] In some possible implementation manners, the channel and the corresponding hoisting holes on the two side plates are on the same center line.

[0006] In some possible implementation manners, avoiding notches are arranged at both ends of all the reinforcing ribs.

[0007] In some possible implementation manners, at least three hoisting holes are arranged on each side plate.

[0008] In some possible implementation manners, the box body further includes a front plate. The corresponding side edges of the front plate are respectively connected to the top plate and the two side plates. A plurality of mounting groove rails are arranged on the outer side surface of the front plate.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The gas box of the inflatable cabinet that is convenient for hoisting in the present utility model is improved on the basis of the existing large gas box. In addition to adding reinforcing ribs to improve the strength, the side plates on both sides are improved.

[0018] Referring to Figures 1 to 3 An inflatable cabinet gas box that is convenient for hoisting, as shown, includes a box body 10 and a plurality of reinforcing ribs 20. The box body 10 includes a top plate 11 and side plates 12 on both sides. The tops of the two side plates 12 protrude from the plane where the top plate 11 is located. A plurality of corresponding hoisting holes 13 are provided in the areas where the two side plates 12 protrude from the top plate 11. All the reinforcing ribs 20 are respectively arranged in the corresponding areas of the top plate 11 where all the hoisting holes 13 are located. The two ends of all the reinforcing ribs 20 are respectively welded and fixed to the two side plates 12.

[0019] Among them, the box body 10 is integrally welded by a plurality of metal plates and can be made of stainless steel. At the same time, the box body 10 further includes a front plate 14. The corresponding side edges of the front plate 14 are respectively connected to the top plate 11 and the two side plates 12. A plurality of installation groove rails 15 are provided on the outer side surface of the front plate 14. Similarly, a rear plate and a bottom plate are also provided, or other plates are used to form a closed structure as a whole. In addition, the above-mentioned reinforcing ribs 20 are also bent from metal materials, which is convenient for processing. The installation groove rails 15 are used for operating mechanisms or other external devices in this application.

[0020] The gas tank of the inflatable cabinet convenient for hoisting is improved on the basis of the existing large gas tank. In addition to adding stiffeners 20 to improve the strength, the side plates 12 on both sides are improved. A protruding part is provided on the top of the side plate 12, and a hoisting hole 13 is provided on the protruding part. Such a setting makes it possible that even if the side plate 12 deforms during the hoisting process, it will not affect the overall structure of the gas tank, and to a certain extent, it can alleviate the influence of the deformation caused by hoisting on the gas tank structure. The stiffeners 20 are respectively arranged in the corresponding areas of the top plate 11 where all the hoisting holes 13 are located. Such a setting can strengthen the structure of the top plate 11 to a certain extent and avoid the deformation of the top plate 11 caused by hoisting. In addition, both ends of the stiffener 20 are welded and fixed to the two side plates 12 respectively, so that a stable structure can be formed among the side plates 12, the top plate 11 and the stiffeners 20, and further improve the strength of the side plates 12 and the top plate 11.

[0021] In some possible implementation manners, all the stiffeners 20 are in a U shape, and the side of the opening of the stiffener 20 is welded and fixed to the top plate 11 to form a hoisting channel; wherein, during the hoisting process, hoisting can be carried out by threading a rope through the hoisting hole 13 and the hoisting channel, and overall, the deformation of the box body 10 during hoisting can be reduced to the greatest extent.

[0022] In the above-mentioned embodiment, the channel and the corresponding hoisting holes 13 on the two side plates 12 are on the same center line. Such a design can facilitate the staff to thread the lifting rope through the hoisting hole 13 and the hoisting channel to a certain extent.

[0023] Of course, in some embodiments, the strength of the two side plates 12 is high enough. At this time, hoisting can be directly carried out by hooking the hoisting hole 13 with a hook. At this time, in order to avoid interference between the hook and the stiffener 20 during the hoisting process, avoiding notches 21 are provided at both ends of all the stiffeners 20. The design of the avoiding notches 21 can facilitate the staff to hook the hook.
