Description

Technical Field

[0001] This utility model belongs to the field of lifting device technology, specifically a lifting device for a catalyst. Background Technology

[0002] SCR (Selective Catalytic Reduction) is commonly used in the treatment of flue gas from industrial boilers. The hoisting and maintenance of the catalyst has always been a relatively troublesome operation. Conventional catalyst hoisting usually involves lifting it from the four corner hooks, but this can cause uneven stress on the catalyst, making it prone to damage. Alternatively, a special hoisting device can be installed on top of the catalyst to balance the force, but this has a limitation: when the catalyst enters the reactor, it needs to be pulled in from the inside, and the hoisting device only has one lug in the middle, which is not conducive to lateral pulling force.

[0003] However, the following problems were found during the implementation of the relevant technology: Existing lifting devices have limitations when moving objects laterally because they only have one lug in the middle. When pulling the catalyst laterally, it is easy to conflict with the vertical pulling force, causing the catalyst to rotate or be damaged by impact. The catalyst needs to be moved slowly, little by little. In addition, the lifting device is relatively large and heavy, making it inconvenient to use in narrow spaces.

[0004] Therefore, we propose a catalyst lifting device. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a catalyst lifting device that, when subjected to lateral tension, does not act on the same point as the vertical tension, but rather on the same surface. This reduces the deformation of the intermediate lugs caused by different tensions, thus ensuring the safety of the catalyst during lifting. Furthermore, it provides some support to the crane body and facilitates control of the crane body's direction, ensuring that the crane does not rotate or deviate unexpectedly during operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a catalyst lifting device, comprising a crane body and a control rod. The crane body includes two crossbeams, with a support frame fixed to each end of the two crossbeams. The two support frames are provided with lifting and fixing ports. A lifting plate is fixedly connected to the middle of the two crossbeams, and three lifting lugs are provided on the lifting plate. A support plate is fixedly connected to the upper surface of the support frame, and a circular groove and a rectangular groove are provided on the support plate. The control rod includes a main rod, with a head rod fixedly connected to one end of the main rod. A rectangular block is fixedly connected to the outer surface of the head rod, and a handle is fixedly connected to the other end of the main rod.

[0007] Preferably, the circular groove is connected to the rectangular groove.

[0008] Preferably, the head rod is movably connected to the circular groove, and the size of the circular groove is larger than that of the head rod.

[0009] Preferably, the rectangular block is fixedly connected to the rectangular groove, and the size of the rectangular groove is larger than that of the rectangular block.

[0010] Preferably, one of the lifting lugs is located in the middle of the lifting plate, and the other two lifting lugs are symmetrically located on both sides of the two crossbeams.

[0011] Preferably, the outer surface of the grip is provided with an anti-slip sleeve, and a positioning handle is fixedly connected to the outer surface of the grip, with the positioning handle and the rectangular block located on the same surface.

[0012] Preferably, the beam, support frame, hanging plate, and support plate are made of high-thickness carbon steel, and the beam, support frame, hanging plate, and support plate are fixed by welding, and the welding is full welding.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When subjected to lateral tension, the lifting device of this utility model will not act on the same point as the vertical tension, but on the same surface. This reduces the deformation of the middle lugs caused by different tensions, thus reducing the impact on the safety of the catalyst during lifting. It also reduces structural damage or deformation caused by local stress concentration, improving the durability and stability of the lifting device. Furthermore, the lifting device reduces the number of outriggers during manufacturing. Compared with traditional catalyst lifting devices, this lifting device is lighter and smaller in size, making it suitable for narrower spaces.

[0015] 2. This utility model, through the cooperation of the support plate, circular groove, rectangular groove, main rod, head rod and rectangular block, can provide certain support for the crane body and facilitate the control of the crane body's direction, ensuring that the crane does not rotate or deviate unexpectedly during operation, reducing the risk of slippage or loss of control of hoisting caused by unstable direction, facilitating the operator's positioning of the catalyst, reducing human error and lowering the possibility of accidents.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a catalyst lifting device, including a crane body 101 and a control rod 201. The crane body 101 includes two crossbeams 1, and a support frame 2 is fixed to each end of the two crossbeams 1. The two support frames 2 are provided with lifting fixing ports 3. A lifting plate 4 is fixedly connected to the middle of the two crossbeams 1. The lifting plate 4 is provided with three lifting lugs 5. A support plate 6 is fixedly connected to the upper surface of the support frame 2. A circular groove 7 and a rectangular groove 8 are provided on the support plate 6. The control rod 201 includes a main rod 9. A head rod 10 is fixedly connected to one end of the main rod 9. A rectangular block 11 is fixedly connected to the outer surface of the head rod 10. A handle 12 is fixedly connected to the other end of the main rod 9.

[0023] Specifically, the circular groove 7 is connected to the rectangular groove 8.

[0024] Furthermore, the head rod 10 is movably connected to the circular groove 7, and the size of the circular groove 7 is larger than that of the head rod 10.

[0025] Furthermore, the rectangular block 11 is fixedly connected to the rectangular groove 8, and the size of the rectangular groove 8 is larger than that of the rectangular block 11.

[0026] It is worth noting that one lifting lug 5 is located in the middle of the hanging plate 4, and the other two lifting lugs 5 are symmetrically located on both sides of the two crossbeams 1.

[0027] It is worth noting that the outer surface of the grip 12 is provided with an anti-slip sleeve 13, and a positioning handle 14 is fixedly connected to the outer surface of the grip 12. The positioning handle 14 and the rectangular block 11 are located on the same surface.

[0028] It is worth mentioning that the crossbeam 1, support frame 2, hanging plate 4, and support plate 6 are made of high-thickness carbon steel. The crossbeam 1, support frame 2, hanging plate 4, and support plate 6 are fixed by welding, and the welding adopts full welding.

[0029] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: During manufacturing, a hanging lug 5 is added to the left and right sides of the original hoist lifting device. Specifically, support frames 2 are welded to both ends of the two crossbeams 1, and a hanging plate 4 is welded in the middle of the two crossbeams 1. Three hanging lugs 5 are set on the hanging plate 4, so that when the crane body 101 is subjected to lateral tension, it will not act on the same point as the vertical tension, but on the same surface. This also reduces the deformation of the middle hanging lug 5 caused by different tensions, which affects the safety of the catalyst during hoisting. At the same time, all parts that need to be welded are fully welded. When hoisting through the crane body 101, the operator can hold the control rod 201 and pass the head rod 10 through the circular groove 7, while the rectangular block 11 passes through the rectangular groove 8. Then, the operator manually rotates the handle 12, thereby rotating the main rod 9, the head rod 10, and the rectangular block 11. The rectangular block 11 and the head rod 10 then lock the support plate 6, thereby providing support for the crane body 101 and controlling its direction.
