Abstract
The present invention relates to gas chamber piston system hangs method for dismounting under a kind of accident condition, comprising: 1) carries out piston after pressure in gas chamber reaches equilibrium valve and remove operation；2) vertical plate lifting lug is welded on every gas chamber column, vertical plate lifting lug is correspondingly arranged at piston and winds up the lower section of truss；Piston truss upright-column is connect with vertical plate lifting lug by chain hoist, prevents piston in work progress mobile；3) piston is winded up and is reinforced between truss and gas chamber column using the reinforcement that winds up, and is reinforced between gas chamber column and piston truss upright-column using lower edge reinforcement；4) crane reaches on the outside of the corresponding gas chamber of piston starting cutting region, carries out lifting and prepares；5) by starting cutting region along removing by several times by cutting region clockwise or counterclockwise when piston is removed, the piston component after subregion is cut hangs original position by crane respectively, finishes until piston is all removed.Operation of the present invention is simple, highly-safe, and dismounting is high-efficient, and construction cost is low.
Description
Technical field
The present invention relates to gas chamber technical field of construction more particularly to a kind of thin oil sealing-type dry-type gas chamber accident conditions
The suspension method for dismounting of lower piston system.
Background technique
In recent years, as China's industry is grown rapidly, industry constantly upgrades, and smelting equipment is in terms of enlargement, environmental protection
Development, the projects such as coal gas, steam combined cycle power generating are more and more by major steel mill's exploitation, construction.Gas chamber is as power generation
The auxiliary facility of project enters the peak period of a construction, and the gas chamber built in the past, which also enters, to be concentrated the transformation phase and scrap
Phase, date of retirement are essentially the gas chamber of construction in one's early years, the case where piston can not vacantly be fallen after rise are frequently occurred after run throughout the year.
Authorization Notice No. is that the Chinese patent of CN101709829B discloses a kind of " dismantling method of coal gas storage cabinet ", will
Piston is down to bottom of cabinet bulk and then is removed；For the thin oil sealing-type dry-type gas chamber under accident condition when piston clamping stagnation exists
When a certain position, bottom of cabinet bulk can not be down to；Removing piston system in the case is one and compares difficult task, only
The method that can be removed using suspension, suspension removes piston system because piston system weight is big, span is big, and piston has shifting at any time
Dynamic possibility, therefore lead to that difficulty of construction is big, risk is big.
Summary of the invention
The present invention provides gas chamber piston system hangs method for dismounting under a kind of accident condition, the side removed using suspension
Method removes the piston for being trapped in a certain position because of accident, easy to operate, highly-safe, and dismounting is high-efficient, is constructed into
This is low.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
Gas chamber piston system hangs method for dismounting under a kind of accident condition, which comprises the steps of:
1) accident condition lower piston is trapped in a certain position, removes before piston system first with air by the coal gas in gas chamber
It cements out, piston is carried out after pressure in gas chamber reaches equilibrium valve and removes operation；
2) vertical plate lifting lug is welded on every gas chamber column, vertical plate lifting lug is correspondingly arranged at piston and winds up under truss
Side；Piston truss upright-column is connect with vertical plate lifting lug by chain hoist, prevents piston in work progress mobile；
3) piston is winded up and is reinforced between truss and gas chamber column using the reinforcement that winds up, close to piston lower edge truss
Gas chamber column and piston truss upright-column between reinforced using lower edge reinforcement；
4) crane reaches on the outside of the corresponding gas chamber of piston starting cutting region, carries out lifting and prepares；
5) by starting cutting region along being removed by several times by cutting region clockwise or counterclockwise when piston is removed, by subregion
Piston component after cutting hangs original position by crane respectively, finishes until piston is all removed.
The reinforcement that winds up, lower edge frame Gu Liang are made of I-steel.
The cutting uses gas cutting mode.
Compared with prior art, the beneficial effects of the present invention are:
The method of the invention removes piston using subregion, without Large-scale Hoisting equipment, without setting up support leg
Hand cradle is realized and utilizes less tooling, equipment, that is, dismountable suspension superelevation, the purpose of large span piston system, and speed of constructing
It is low to spend fast, easy-to-operate, construction cost, to reduce the cost of enterprise, improves the economic benefit of enterprise.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
Gas chamber piston system hangs method for dismounting, includes the following steps: under a kind of accident condition of the present invention
1) it as shown in Figure 1, accident condition lower piston 8 is trapped in a certain position, removes before piston system first with air by coal
Coal gas replacement in gas holder comes out, and piston 8 is carried out after pressure in gas chamber reaches equilibrium valve and removes operation；
2) vertical plate lifting lug 3 is welded on every gas chamber column 5, vertical plate lifting lug 3 is correspondingly arranged at piston and winds up truss 9
Lower section；Piston truss upright-column 7 is connect with vertical plate lifting lug 3 by chain hoist 2, prevents piston 8 in work progress mobile；
3) piston is winded up and is reinforced between truss 9 and gas chamber column 5 using the reinforcement 1 that winds up, close to piston lower edge
It is reinforced between the gas chamber column 5 and piston truss upright-column 7 of truss 10 using lower edge reinforcement 4；
4) crane 6 reaches piston 8 and originates on the outside of the corresponding gas chamber of cutting region, carries out lifting and prepares (as shown in Figure 2)；
5) as shown in figure 3, as starting cutting region along (direction shown in arrow in figure) or inverse time clockwise when piston 8 is removed
Needle is removed by several times by cutting region, and the piston component after subregion is cut hangs original position by crane 6 respectively, until piston
8 whole remove finish.
The reinforcement 1 that winds up, lower edge frame are consolidated beam 4 and are made of I-steel.
The cutting uses gas cutting mode.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
