Abstract
The invention discloses a front-back water cooled wall reverse carrying hoisting method for a dry bottom hopper section. The method comprises the following steps that a water cooled wall is reversely laid on a boiler zero-meter combined platform, equipment and the size are inspected, and a ball passing test and a spectrum test are carried out; combining and opening joining, welding and edge jointing are carried out, seal welding is completed, and secondary ball passing and pipe opening blocking are carried out after welding is completed; a dry bottom hopper section rear side rigid beam, an upper aligned horizontal beam and a connecting piece are mounted on a completed water cooled wall assembly, and a leveling beam and a sling pin shaft are perfected; and winch pulley sets are arranged at the left-most position and the right-most position of a rear side water cooled wall combustor hole respectively at certain height. According to the method, the problem that hoisting control is hard due to midair rotation of a lifting appliance and pulley overturn in hoisting work when a hole is reserved in a ceiling is solved, and frame erecting and dismounting work, brought by ceiling hole reserving or forming, for later restoration is solved; and the high altitude danger coefficient of mounting and welding work, ultrasonic grinding and other procedures is lowered, and process arrangement is more reasonable and economical.
Description
Technical field
The present invention relates to power plant's component devices hoisting technology field, before and after particularly relating to furnace hopper section, water-cooling wall has oppositely removed hanging method.
Background technology
On-the-spot boiler furnace hopper lifting machine and steel wire rope walking can require to be reserved with suspending hole, before and after furnace hopper section of the present invention, water-cooling wall has oppositely removed hanging method, break through traditional approach boiler body furnace hopper section and needs are installed, avoid this problem, thus reach boiler roof tube and accessory device installs in advance, meet the construction safety of individual works schedule requirement and ceiling area, and the header of more than roof tube, liaison tube can be made to go into operation in advance and carry out smoothly.
Summary of the invention
The present invention reserves problem in order to avoid lifting machine and the steel wire rope suspending hole of bringing of walking, and before and after providing furnace hopper section, water-cooling wall has oppositely removed hanging method.
For achieving the above object, before and after providing furnace hopper section, water-cooling wall has oppositely removed hanging method, comprises the steps: in the present invention
Oppositely water-cooling wall is laid at boiler zero meter of combined platform, checkout facility and size, carry out through ball test and spectral test, combination counterpart, welding, piece complete seal welding, carry out secondary after having welded to lead to ball and to go forward side by side the shutoff of line pipe mouth, buckstay on rear side of furnace hopper section installed by the water-cooling wall assembly completed, upper neat horizontal beam and connector, improve smoothing beam and suspender belt bearing pin;
Winch pulley block is arranged in a rear side water-cooling wall burner Kongzui left side and the rightest two positions at certain altitude, each a set of; In water-cooling wall identical absolute altitude boiler center, front side arranges that a set of hoist engine is as auxiliary adjustment lifting measure;
Rear side master hangs every platform winch pulley block and uses steel wire rope and assembly pulley to lift by crane;
The adjustment of one, front side coordinates hoist engine and assembly pulley to adopt ten equally, and one is stressed;
At equipment and earth surface place cushioning flitch before lifting, tighten three hoist engines, check each assembly pulley, leading block, steel wire rope, in lifting process, two masters hang hoist engine and hoist, and hoist engine coordinates lifting;
Along with hanging thing component variations, front side coordinates hoist engine to carry out folding and unfolding adjustment in time, when arriving rear side assembly absolute altitude in place about 2 meters, is hung up properly by the 10 tons of jacks in six, outside hung up properly in advance and adjusts.
The invention has the beneficial effects as follows: improve being advanced by more than one month for more than ceiling and ceiling all equipment to be installed installations, late if any furnace hopper section equipment arrival, this scheme manifests benefit effect more, reduce the demand of renting large-scale more than 10 tons hoist engines (hold rope and measure 1000 meters), the spinning in the air of suspender in lifting operation when avoiding ceiling preformed hole, pulley overturns the lifting brought and controls difficulty, avoid shelf that ceiling is reserved or perforate brings later stage recovers to take and tear operation open, reduce installation and weld job, the high-altitude danger coefficient of the operations such as ultrasonic polishing, processing arrangement is more reasonable and economical.
Detailed description of the invention
Be described in detail below with reference to embodiments of the invention.
Before and after furnace hopper section, water-cooling wall has oppositely removed hanging method, comprises the steps:
Oppositely water-cooling wall is laid at boiler zero meter of combined platform, checkout facility and size, carry out through ball test and spectral test, combination counterpart, welding, piece complete seal welding, carry out secondary after having welded to lead to ball and to go forward side by side the shutoff of line pipe mouth, buckstay on rear side of furnace hopper section installed by the water-cooling wall assembly completed, upper neat horizontal beam and connector, improve smoothing beam and suspender belt bearing pin;
Winch pulley block is arranged in a rear side water-cooling wall burner Kongzui left side and the rightest two positions at certain altitude, each a set of; In water-cooling wall identical absolute altitude boiler center, front side arranges that a set of hoist engine is as auxiliary adjustment lifting measure;
Rear side master hangs every platform winch pulley block and uses steel wire rope and assembly pulley to lift by crane;
The adjustment of one, front side coordinates hoist engine and assembly pulley to adopt ten equally, and one is stressed;
At equipment and earth surface place cushioning flitch before lifting, tighten three hoist engines, check each assembly pulley, leading block, steel wire rope, in lifting process, two masters hang hoist engine and hoist, and hoist engine coordinates lifting;
Along with hanging thing component variations, front side coordinates hoist engine to carry out folding and unfolding adjustment in time, when arriving rear side assembly absolute altitude in place about 2 meters, is hung up properly by the 10 tons of jacks in six, outside hung up properly in advance and adjusts.
Claims (1)
1. before and after furnace hopper section, water-cooling wall has oppositely removed hanging method, it is characterized in that, comprises the steps:
Oppositely water-cooling wall is laid at boiler zero meter of combined platform, carry out conscientious equipment inspection and inspection size, complete through ball test and spectral test, by technical standard requirement combination counterpart, welding, piece complete seal welding, carry out secondary after having welded and lead to ball and carry out mouth of pipe close measure, then again buckstay on rear side of furnace hopper section is installed on the water-cooling wall assembly completed, horizontal beam and connector are all gone up together, smoothing beam is perfect, and suspender belt bearing pin is not omitted, and acceptance(check) is waited to hang;
Winch pulley block is arranged in a rear side water-cooling wall burner Kongzui left side and the rightest two positions at certain altitude, each a set of; In water-cooling wall identical absolute altitude boiler center, front side arranges that a set of hoist engine is as auxiliary adjustment lifting measure;
