Specifically, in the present embodiment, the plurality of wall plates 12 are provided with notches 121 at the top corners 111 of the frame 11. The wall plate 12 corresponds to the two corners of the wall plate 12 near the top at the top corners 111 of the frame 11. That is, notches 121 are provided at both corners of the top of the wall plate 12. The gap 121 allows clearance between the wall plate 12 and the frame 11. Thus, the edges of the notch 121 form a lifting hole 13 with the frame 11. The hoisting rope can be hoisted and fixed with the skid-mounted cold box 10 through the hoisting hole 13. The skid-mounted cold box 10 only needs to be provided with the hoisting holes 13 at the top corners 111 of the frame 11. No lifting hole can be arranged at the bottom corner 112 to avoid the structure complexity.

The skid-mounted cold box 10 of the present embodiment eliminates the external lifting lug structure, and depends on the self structure of the skid-mounted cold box 10, and the internal space of the skid-mounted cold box 10 is utilized through the notch 121 on the wall plate 12, and the frame 11 is utilized as a support, and the top corner 111 of the frame 11 is made into the hoisting hole 13. The hoisting hole 13 completely utilizes the inner space of the notch 121, the external dimension is not affected, the transportation efficiency can be improved to the maximum efficiency, and the conventional lifting lug is prevented from protruding out of the outer side of the skid-mounted cold box 10, occupying the transportation space and causing adverse effect on the transportation process.

Specifically, in the present embodiment, the wall plate 12 includes a top wall plate provided on the top of the frame 11 and a side wall plate provided on the side of the frame 11. Specifically, a top wall plate 122, a first side wall plate 123 and a second side wall plate 124 are disposed at a top corner 111 of the frame 11.

The hoisting rope can enter from one hoisting hole and extend out from the other hoisting hole to realize the fixed connection with the skid-mounted cold box 10.

In other embodiments, the number of the lifting holes formed in the top wall plate and the two adjacent side wall plates at the top corner 11 may be 2, 4, or the like. The skid-mounted cold box 10 is only required to ensure that at least two hoisting holes are communicated. Namely, the hoisting rope can be ensured to penetrate through one hoisting hole and extend out of the other hoisting hole. Even, only one lifting hole 13 can be arranged at one top corner 111. The hoisting rope can be designed with a special connecting piece to be connected with the skid-mounted cold box 10 through the hoisting hole 13.

The wall plate 12 is provided with a reinforcing structure 14 at the edge of the notch 121. Both ends of the reinforcing structure 14 are welded to the frame 11, respectively. The reinforcing structure 14 may be a tube, a bar, or the like.

In particular, the reinforcing structure 14 may be a square steel tube. The notch 121 is surrounded on the periphery by the reinforcing structure 14 and the side frame 117. During hoisting, the stress on the hoisting hole is transmitted to the frame 11 through the reinforcing structure 14, so that the stress can be dispersed. On one hand, the reinforcing structure 14 can enhance the strength of the edge of the notch 121 and avoid the phenomena of tearing and the like of the edge of the notch 121; on the other hand, the reinforcing structure 14 can protect the edge of the notch 121 and prevent the wall plate 12 from being damaged when the hoisting rope deviates.

Referring to fig. 2, 3 and 4, the first sidewall 123 has a first notch 126. The first notch 126, the first top frame 115 and the side frame 117 form a first hoisting hole 131. The shape of the first notch 126 gradually shrinks from top to bottom in a direction along the side frame 117. In particular, in the present embodiment, the shape of the first notch 126 is similar to a right-angled trapezoid. The first top frame 115 and the side frame 117 are right-angled sides of a right-angled trapezoid respectively.

The second side wall panel 124 is provided with a second notch 128. The second gap 128, the second top frame 116 and the side frame 117 form a second hoisting hole 132. The shape of the second notch 128 gradually shrinks from top to bottom in a direction along the side frame 117. In particular, in the present embodiment, the second notch 128 is shaped like a right-angled trapezoid. The second top frame 116 and the side frame 117 are respectively right-angled sides of a right-angled trapezoid.

The top corner 111 of the top wall panel 12 is provided with a third notch 129. The third gap 129 forms a third hoisting hole 133 with the first top frame 115 and the second top frame 116. The third notch 129 is rectangular or square in shape.

The first lifting hole 131, the second lifting hole 132 and the third lifting hole 133 are communicated with each other. The hoisting rope is fixedly connected with the skid-mounted cold box 10.

Referring to fig. 5, in the present embodiment, a sealing plate 15 is disposed at an inner side of the top corner 111 of the frame 11. The side edges of the sealing plate 15 are fixedly connected to the top wall plate 12, the first side wall plate 123 and the second side wall plate 124, respectively, and seal the receiving cavity. The closing plate 15 is provided with a slope 151, and the slope 151 is inclined toward the outer side of the hoisting hole 13. The side edge of the sealing plate 15 is fixedly connected with the edge of the notch 121.

A closure plate 15 may close the receiving cavity. The sealing effect of the containing cavity is prevented from being reduced due to the opening of the notch 121 on the wall plate 12. And, the inclined plane 151 of shrouding 15 becomes the downward sloping by the inboard of hole for hoist 13, and shrouding 15 both can make things convenient for the penetration of hoist rope, can effectively avoid the inside ponding of hole for hoist 13 again.

Specifically, in the present embodiment, a connection frame 119 is further provided between the adjacent side frames 117. The connection frame 119 connects the two side frames 117. The connection frame 119 may be plural. Since the side frames 117 are long in length, it is not easy to maintain a stable positional relationship between the side frames 117. The connection frame 119 may reinforce a stable connection between the adjacent side frames 117.

The intersection of two adjacent connecting frames 119 and one side frame 117 is a convergence point 113. The three connection frames 119 and the two side frames 117 form two convergence points 113 therebetween. The two convergence points 113 are located on one side of the skid mounted cold box 10. The auxiliary hoisting hole 134 is arranged at the convergence point 113. The structure at each convergence point 113 is similar, and the structure of one of the convergence points 113 will now be described.

The convergence point 113 includes two connecting frames 119, a side frame 117 and two adjacent side wall plates 12. The two adjacent side wall panels 12 are provided with auxiliary notches 120 at the convergence point 113. The auxiliary gap 120 forms an auxiliary hoisting hole 134 corresponding to the frame 11. At each convergence point 113, there may be two auxiliary notches 120 and two auxiliary lifting holes 134. The auxiliary hoist hole 134 has a shape and structure substantially similar to those of the hoist hole 13 described above. The auxiliary lifting hole 134 also has a closing plate 15 and a reinforcing structure 14, and the detailed structure of the auxiliary lifting hole 134 is not described herein.

In the process of vertically hoisting the skid-mounted cold box 10, the auxiliary hoisting of an auxiliary hoisting machine is required to be added. The auxiliary crane is connected with the skid-mounted cold box 10 through the auxiliary hoisting hole 134. The auxiliary crane can assist in erecting the skid-mounted cold box 10 from the side of the bottom of the skid-mounted cold box 10 through the auxiliary hoist holes 134.

And, the connection frame 119 is adjacent to the bottom of the frame 11, and the auxiliary hoist hole 134 is adjacent to the bottom of the frame 11. The auxiliary hoisting holes 134 can hoist and fix the skid-mounted cold box 10 from the bottom of the frame 11. In the hoisting process, the auxiliary hoisting hole 134 close to the bottom is matched with the hoisting hole 13 at the top, so that the position of the skid-mounted cold box 10 in the air can be controlled more effectively.
