In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Fig. 2 shows a schematic structural diagram of a hoisting structure for a tail gas treatment device according to the present disclosure. As known to those skilled in the art, the exhaust gas treatment device is a device for treating exhaust gas of a vehicle, and includes a case 100, and the case 100 has a substantially rectangular parallelepiped structure. As is clear from fig. 2 to 4, the hoisting structure 200 is composed of a first support 210, a first steel strip 220, and a first clamping mechanism. The first bracket 210 is placed on the top of the box 100 and includes a first end 211 and a second end 212, wherein the first end 211 and the second end 212 of the first bracket 210 are respectively located at or near two opposite top edges of the box 100. The first steel band 220 surrounds the sides and the bottom of the case 100, and one end of the first steel band 220 is fixed at the first end 211 of the first bracket 210. The first clamping mechanism is used to fix the other end of the first steel strip 220 at or near the second end 212 of the first bracket 210, wherein under the action of the first clamping mechanism, the other end of the first steel strip 220 moves towards the second end 212 of the first bracket 210 until the first steel strip 220 can cling to the outer surfaces of the side and bottom of the box 100. At this time, both ends of the first steel strip are located at or near two opposite top edges of the tank, respectively, thereby eliminating a gap between the first steel strip and the side of the tank. Meanwhile, the first steel belt does not adopt a sectional structure as in the prior art, so that a gap which may exist between the first steel belt and the bottom of the tank body is eliminated. This will greatly reduce the pre-load force of the first steel strip generated by the existence of the gap in a high temperature environment and improve the reliability and stability of the hoisting structure.

Specifically, the first clamping mechanism further includes: the limiting part 213, the first rotating shaft 240, the second rotating shaft 250 and the tightening part 260. As shown in fig. 2, the stopper 213 is fixed to the second end 212 of the first bracket 210. The first shaft 240 abuts against the stopper 213. The second rotating shaft 250 is installed at the other end of the first steel belt 220. The tightening member 260 may take the form of a hexagon socket head cap screw, and is in turn rotatably coupled to the first and

second shafts

240 and 250 such that the tightening member 260 can rotate about its own axis, wherein the tightening member 260 is threadably coupled to one or both of the first and

second shafts

240 and 250. The first shaft 240 is restrained by the restraining part 213, and the second shaft 250 moves toward the restraining part 213 while the tightening member 260 rotates until the first steel band 220 can be tightly attached to the outer surfaces of the side and bottom of the box 100, so that the first shaft 240 and the second shaft 250 are tightly clamped together when the tightening is completed, and the first steel band 220 is tightly clamped to the box 100.

During the installation of the hoisting structure, an operator first fixes one end of the first steel strip 220 to the first end 211 of the first bracket 210 via the third rotating shaft 230, and places the first bracket 210 on the top of the box 100. Subsequently, the other end of the first steel belt 220 is sleeved on the second rotating shaft 250. The tightening member 260 is then sequentially screwed into the first rotating shaft 240 and the second rotating shaft 250. When the first shaft is about to be screwed into the predetermined screwing position, the first shaft 240 abuts against the stopper 213 of the first bracket 210. Because the limiting portion 213 limits the first rotating shaft 240, the second rotating shaft 250 gradually approaches the first rotating shaft 240 or the limiting portion 213 in the process of rotating the tightening member 260 until the tightening member 260 tightens the first rotating shaft 240 and the second rotating shaft 250 at the same time, and the first steel strip 220 can tightly cling to the outer surfaces of the side portion and the bottom portion of the box 100, so that the tightening of the first steel strip to the box of the exhaust gas treatment device is completed. In addition, since the first steel strip does not have any gap with the outer surface of the side and bottom of the box body, the influence of high temperature on the stress of the steel strip is favorably reduced.

It will be readily appreciated by those skilled in the art that the first clamping mechanism may also take the form of a quick clamp such that the other end of the first steel strap 220 can be quickly secured by clamping at or near the second end 212 of the first bracket 210.

In order to stably hoist the box body of the tail gas treatment device to a target position, the hoisting structure can adopt two steel belts arranged in front and back for hoisting. Specifically, the hoisting structure 200 further comprises a second bracket 270, a second steel band (not shown) and a second clamping mechanism (not shown). The second bracket 270 is also placed on top of the box 100 and includes a first end 271 and a second end 272 located at or near two opposite top edges of the box 100, respectively. The second steel band surrounds the sides and the bottom of the case 100, and one end of the second steel band is fixed at the first end 271 of the second bracket 270. A second clamping mechanism is used to secure the other end of the second steel strap at or near the second end 272 of the second bracket 270. Under the action of the second clamping mechanism, the other end of the second steel strip moves toward the second end 272 of the second bracket 270 until the second steel strip abuts against the outer surfaces of the sides and bottom of the box 100. In this case, the first bracket 210 and the second bracket 270 may be arranged in parallel and integrally formed to constitute a bracket assembly, and the bracket assembly, i.e., the first bracket 210 and the second bracket 270, is made of cast steel or aluminum alloy. In order to improve the overall structural strength of the bracket assembly, the bracket assembly may be provided with a plurality of reinforcing ribs extending in a longitudinal direction of the first bracket or the second bracket or extending in a direction perpendicular to the longitudinal direction of the first bracket or the second bracket.

With continued reference to fig. 3, the first bracket 210 and the second bracket 270 may be fixed at a target location, such as a frame of an exhaust end of an engine, by bolt fastening, wherein the first bracket 210 is provided with a first threaded hole 214 for receiving a bolt, and the second bracket 270 is provided with a second threaded hole 274 for receiving a bolt.

Considering that the tightening member may interfere with the end of the first steel belt, the other end of the first steel belt 220, which is sleeved on the second rotating shaft 250, is further provided with an opening 221 for allowing the bottom of the tightening member 260 to pass through, as shown in fig. 4.

According to an exemplary embodiment, the first steel strip 220 and the second steel strip are made of high temperature resistant stainless steel. The high temperature resistant stainless steel may be an austenitic chromium nickel stainless steel, such as 310S, which has good oxidation and corrosion resistance, because of the high percentage of chromium and nickel, which provides good creep strength, which can be operated continuously at high temperatures, and which has good high temperature resistance.

Furthermore, the utility model also provides a tail gas processing apparatus, tail gas processing apparatus is provided with foretell hoisting structure.

Additionally, the utility model also provides a vehicle, the vehicle disposes foretell tail gas processing apparatus. The tail gas treatment device is assembled on a frame near an exhaust pipe of an engine, wherein the engine can be a gasoline engine, a diesel engine, a natural gas engine, a hydrogen engine and the like.

To sum up, the utility model discloses a clearance between lateral part and the bottom that is used for tail gas processing apparatus's hoisting structure to eliminate steel band and tail gas processing apparatus box can reduce the influence of high temperature to the steel band atress favorably. Further, the use of the integrated steel belt can simplify the structure and reduce the number of parts. It is therefore highly recommended to arrange the hoisting structure in an exhaust gas treatment device and to popularize and apply the exhaust gas treatment device in a vehicle.
