Description

Technical Field

[0001] This utility model relates to the field of reaction vessel operation, specifically to an auxiliary disassembly device for the bottom valve of a reaction vessel. Background Technology

[0002] Currently, the reactor's discharge valve and emergency discharge valve (such as...) are being disassembled. Figure 2 When disassembling the valve (as shown), at least three people are needed to lift the valve body upwards, and two people are needed to remove the flange bolts. Multiple people are crammed into a confined space to support the valve manually, making it difficult to control the angle, resulting in significant disassembly challenges. Using manual lifting of the reactor bottom valve for disassembly will lead to the following problems:

[0003] 1. The bottom valve of the reactor is heavy and irregularly shaped, with an unstable center of gravity. It requires at least 3 people to lift it. If multiple people are working on it, the bottom valve may slip off and cause injury.

[0004] 2. Two people were disassembling the bolts connecting the reactor and the bottom valve from different angles. After the bolts loosened, the bolts became stuck due to the uneven force applied by the people lifting them and the difficulty in controlling the angle. This made the bolts difficult to disassemble.

[0005] 3. Five people in the same position in a small space is not conducive to work. Summary of the Invention

[0006] This utility model addresses the problem that currently, when disassembling the discharge valve and emergency discharge valve of a reactor, at least three people are needed to lift the valve body upwards, and two people are needed to remove the flange bolts. Multiple people are crammed into a narrow space to use manpower for support, making it difficult to control the angle, resulting in high disassembly difficulty. Furthermore, multiple people operating the valve may cause the bottom valve to slip and injure personnel. This utility model provides an auxiliary disassembly device for the bottom valve of a reactor.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a reaction vessel bottom valve auxiliary disassembly device, including a hydraulic lifting forklift, on which a working platform is fixed on the two steel forks of the hydraulic lifting forklift, and a horizontally arranged first steel pipe and an inclined second steel pipe are fixed on the working platform. The length of the first steel pipe is less than or equal to the distance between the two lifting lugs of the discharge valve of the reaction vessel to be disassembled, and the inclination angle of the second steel pipe is consistent with the inclination angle of the emergency discharge valve of the reaction vessel to be disassembled.

[0008] Furthermore, the hydraulic lifting forklift 1 has two parallel crossbeam supports that are perpendicular to the steel forks connected to its two steel forks by bolts. Each end of the two crossbeam supports is welded with a vertically set upright support. The top of the four upright supports is welded together with a horizontally set working platform.

[0009] Furthermore, the first steel pipe is a DN32 stainless steel pipe, and the second steel pipe is a DN50 stainless steel pipe.

[0010] Furthermore, the hydraulic lifting forklift is a manual hydraulic lifting forklift.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model features a reasonable structural design, effectively supporting the bottom valve of a reactor discharge vessel, reducing workload and manpower, and preventing the valve from slipping and injuring workers. It also boasts advantages such as simple structure, low cost, and reusability. This invention is suitable for various locations requiring support for reactor bottom valve operations.

[0017] The present invention will be further described below with reference to specific embodiments. Example 1

[0018] like Figure 1 As shown, an auxiliary disassembly device for a reactor bottom valve includes a hydraulic lifting forklift 1. A working platform 4 is fixed on the two steel forks of the hydraulic lifting forklift 1. A horizontally arranged first steel pipe 5 and an inclined second steel pipe 6 are fixed on the working platform 4. The length of the first steel pipe 5 is less than or equal to the distance between the two lifting lugs 10 of the discharge valve 8 of the reactor to be disassembled. The inclination angle of the second steel pipe 6 is consistent with the inclination angle of the emergency discharge valve of the reactor to be disassembled.

[0019] Furthermore, the hydraulic lifting forklift 1 has two parallel crossbeam supports 3 connected to its two steel forks by bolts. Each end of the two crossbeam supports 3 is welded with a vertically set upright support 2. The tops of the four upright supports 2 are welded together with a horizontally set working platform 4.

[0020] Furthermore, the first steel pipe 5 is a DN32 stainless steel pipe, and the second steel pipe 6 is a DN50 stainless steel pipe.

[0021] Furthermore, the hydraulic lifting forklift 1 is a manual hydraulic lifting forklift.

[0022] like Figure 1 As shown, a support frame is welded using an upright bracket 2 and a crossbeam bracket 3. A working platform 4 is welded onto the frame. A DN32 stainless steel pipe (first steel pipe 5) is horizontally welded onto the working platform, and a DN50 stainless steel pipe (second steel pipe 6) is welded diagonally. These are then bolted to a manual hydraulic lifting forklift 1. Figure 2 As shown, when disassembling the discharge valve 8 of reactor 7, a manual hydraulic lifting forklift 1 is used to raise the horizontally welded DN32 stainless steel pipe to the middle of the two lifting lugs 10 on the discharge valve 8. A lead screw is then passed through the DN32 stainless steel pipe and the lifting lugs 10, and the two ends are tightened with nuts before disassembly. When disassembling the emergency discharge valve 9 of reactor 7, the manual hydraulic lifting forklift 1 is raised to a suitable height, the angle is adjusted, and the valve cover 11 of the emergency discharge valve 9 is inserted into the obliquely welded DN50 stainless steel pipe before disassembly. This effectively reduces the number of workers, lowers the workload, and prevents personnel injury caused by the bottom valve of the reactor slipping.
