Boiler maintenance gray supporting platform and building method thereof

Abstract

The invention belongs to the original product of the same industry at home and abroad and provides a boiler maintenance gray supporting platform. The boiler maintenance gray supporting platform is formed by a plurality of unit bearing assemblies through series arrangement and connection; every unit bearing assembly is formed by a unit bearing support, a unit supporting plate and two unit triangular supporting and anti-skid devices; the unit supporting plate is laid on the surface of the unit bearing support; the two unit triangular supporting and anti-skid devices are arranged at two ends of the lower portion of the unit bearing support; the two ends of the unit bearing support and the bottom ends of the two unit triangular supporting and anti-skid devices which are utilized as supporting feet are used for abutting against the gray slope surface of the boiler water wall. According to the boiler maintenance gray supporting platform, the triangle which is stable in structure is adopted to support the steel beam integral structure, so that the boiler maintenance gray supporting platform is firm and reliable and high in security; the integral structure is level and smooth and free of gaps and holes endangering the personal safety and equipment safety; the assembly and disassembly is rapid and convenient; the requirements of the length of the operation surface for boiler maintenance can be met through free combination according to the length of a boiler and the boiler maintenance gray supporting platform can be customized according to the widths which are required by different boiler types.

Description

Technical field [0001] The present invention involves the field of boiler maintenance technology, which specifically involves a new type of boiler maintenance gray port support platform. It can be used for the support working surface set by the boiler ash at the upper part of the boiler ash at the power plant, which provides a flat operating surface for the boiler maintenance equipmentIt can be used in conjunction with the various maintenance equipment of the boiler and can also be used alone; the effect is excellent, the boiler maintenance support platform can be combined according to the length of the boiler to achieve the required work surface length requirements for the boiler maintenance; it can also be according to the needs of different furnace types.Customized width.The safety, convenience, speed and practicality of its equipment belong to the original products of the same industry at home and abroad. Background technique [0002] The existing working platform for boiler ...

AI Technical Summary

Problems solved by technology

[0004]1. Due to structural reasons, it is easy to cause the whole or part of the working surface to collapse, and there are high hidden dangers to personal safety and equipment safety

[0005]2. It is laborious to use the steel pipe scaffolding to build the maintenance work face: passing and transporting dozens of tons of scaffolding materials through the manhole with a diameter of less than 500MM in the airtight container to build 600 Two or so cubic scaffolding steel pipes and fasteners enter the furnace, and then build and connect the steel pipes one by one to build a suspended working surface with a height of more than 6-12 meters, which is a very labor-intensive and dangerous work.

[0006]3. Time-consuming gray work platform built with steel pipe scaffolding: Take the 1 million kilowatt unit boiler as an example, build and disassemble about 660 cubic scaffold steel pipe fasteners It takes at least 3 days to support the platform with gray scaffolding, which is not only laborious but also time-consuming

[0007]4. The cost of the gray working platform built with steel pipe scaffolding is too high: due to the continuous rise of steel and labor costs, the cost of scaffolding is also very high. Taking a 10,000-kilowatt boiler as an example, it takes more than 150,000 RMB to build a gray-mouth support work surface, and it is showing a rising trend

[0008]5. Damage to the inner wall of the boiler during the construction process using steel pipe scaffolding materials: the water chestnuts at both ends of the steel pipe are sharp, because they are in direct contact with the inner wall of the boiler during construction, so it is easy to Damage to boiler water wall tubes

[0009] In the process of building and dismantling, it is inevitable that steel pipes and metal connectors will fall from high altitude, which will not only easily cause personal injury to the on-site staff, but also easily cause damage to the water wall of the boiler and other boiler equipment. If it is not repaired in time, it will cause heavy losses to the power plant

[0010] 6. The gray working platform built with steel pipe scaffolding has many potential safety hazards for maintenance personnel and maintenance equipment:

[0011]1) During construction, the risk of working at heights for construction personnel is very high;

[0012]2) Because the load-bearing board on the top is a bamboo raft, the load-bearing capacity of the veneer is very poor, and the aging bamboo raft often breaks, and people are easily missed; Because the top bamboo raft itself is not straight and the steel pipes are not smooth, there are many large gaps (ranging from a dozen centimeters to tens of centimeters) between the bamboo rafts on the working surface of the bamboo rafts laid on the top. It is easy to fall from the gap, and it is easy to cause high-altitude falling objects to pose a great safety hazard to the staff below. There are also gaps that are too large and uneven, and people walking on it can easily fall into the gap and cause personal injury.

[0013]3) Overhaul equipment (especially large-scale overhaul equipment) will often fall over when working and moving, which poses a threat to the personal safety of the overhaul personnel and the overhaul equipment. big security risk

[0014]7. It is very inconvenient to move the maintenance work surface equipment built with steel pipe scaffolding (gray working platform): because the work surface is laid with bamboo rafts, it is uneven and the gaps are very large. Large, 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 get stuck

[0015]8. It is very inconvenient to overhaul the gray working platform built with steel pipe scaffolding: if the parts in contact with the scaffolding need to be overhauled during the maintenance process, the position of the scaffolding needs to be readjusted , when carrying out the overall sandblasting spraying in the furnace (when checking the leakage point in the furnace), it is very inconvenient to remove the places that are in contact with the inner wall of the boiler one by one

When the steel pipe scaffolding is in use, the maintenance personnel consume a lot of physical strength when climbing, and there is no way to carry heavy and large maintenance equipment, which brings a lot of inconvenience to the maintenance work
