Boiler maintenance platform

Abstract

The invention relates to a boiler maintaining platform which is lifted by a lifting rope. The boiler maintaining platform comprises a guide rod and a seat type maintaining table which are formed by assembling, wherein the seat type maintaining table comprises a seat type maintaining chair and a safety seat cushion; the seat type maintaining chair comprises a chair back, a chair surface and a footsupporting surface from top to bottom; the seat surface and the foot supporting surface are horizontally arranged; the rear part of the foot supporting surface is fixed with the front part of the chair surface through a perpendicular connecting rod; the guide rod is horizontally arranged, and comprises a first guide rod arranged on the rear part of the chair back, a second guide rod arranged on the bottom of the chair surface, and a third guide rod which is arranged on the bottom of a connecting rod or the foot supporting surface; and each guide rod is in sliding connection to the seat type maintaining table through a guide tube. The boiler maintaining platform disclosed by the invention is simple in structure, is quick in establishing, is small in integral weight, enables maintaining staff to sit down to maintain, is mechanically controlled to move up and down as well as left and right, can be suitable for inner and outer irregular spaces of a boiler, and is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of boiler maintenance, and in particular relates to a boiler maintenance platform. Background technique [0002] At present, most of the boiler furnace maintenance in thermal power plants in my country adopts the boiler furnace maintenance platform. Conventional maintenance platforms are built layer by layer with scaffolding steel pipes, and then bamboo rafts or fixed grids are laid on them to form a working plane, and maintenance personnel move back and forth between different working planes for maintenance. The boiler furnace maintenance platform has the characteristics of convenient use and high safety. [0003] It is very convenient to use scaffolding to build the maintenance work surface outside the boiler, but it is very troublesome to repair the boiler furnace by building scaffolding, because people or things must pass through the manhole with a diameter of about 450MM. , transport several tons or e...

Problems solved by technology

[0003] It is very convenient to use scaffolding to build the maintenance work surface outside the boiler, but it is very troublesome to repair the boiler furnace by building scaffolding, because people or things must pass through the manhole with a diameter of about 450MM. , transport several tons or even tens of tons of scaffolding steel pipes into the furnace, and then build and connect the steel pipes one by one to build a suspended working surface with a height of several meters or even tens of meters, which is narrow and closed in the boiler, and the light is not good And in an environment with many protruding sharp parts, this kind of construction work is time-consuming, laborious and dangerous. If you are not careful, the scaffolding steel pipe will fall or touch the water wall or other devices in the boiler, which may cause damage to the equipment in the boiler. Damage or damage to the wear-resistant and anti-corrosion protective layer of the instant surface of the water cooling wall, if maintenance personnel accidentally fall, it may cause serious injury

[0004] In such a boiler maintenance environment, it usually takes 2 days to build a scaffolding maintenance platform of about 600 cubic meters, and it takes at least one day to dismantle it, and every day the boiler is shut down will cause great economic losses to the manufacturer. loss; moreover, the price of asking the engineering team to build scaffolding steel pipes is also expensive

[0005] After the scaffold maintenance platform is built, the maintenance personnel move back and forth at different operation levels for maintenance operations, which is dangerous and inconvenient. Due to the obstruction of the scaffold steel pipe, it will also affect the maintenance personnel's spraying wear-resistant layer, defect repair welding and other operations; because There are usually gaps and unevenness between the bamboo rafts or grids laid on the working surface, so when moving large or heavy equipment on the working surface, there is no way to move smoothly on it or it is easy to be stuck, and maintenance personnel also have problems when moving on it. may be tripped

[0006] As for the hoisting boiler maintenance platform, its construction is simple and the cost is low, but because it cannot adapt to the irregular space environment in the boiler, there are many detection dead angles, and the hoisting boiler maintenance platform has a large dead weight. If it touches the inner wall of the boiler when it is rising or falling, it is easy to cause damage to the internal facilities of the boiler, and the loss outweighs the gain. Therefore, manufacturers seldom use hoisting boiler maintenance platforms for maintenance.

[0007] In addition, when the hoisting boiler maintenance platform is used for maintenance, the maintenance personnel stand unstable on the boiler maintenance platform for a long time, and need to walk back and forth constantly, which is easy to be tired and dangerous
