Description
Technical field
The invention belongs to gas chamber field, and in particular to one kind reduces rubber film sealed dry type coal gas cabinet leveling balance weight
Leveling method.
Background technology
Rubber film sealed dry type gas chamber is widely used in the recycling storage of iron and steel enterprise's by-product gas, with shown in Fig. 1
Exemplified by two section type rubber film sealed dry type gas chamber, the gas chamber of this cabinet type is by can in bottom of cabinet plate, side plate, cabinet top plate and cabinet
Formed with the piston and T baffles that move up and down, in the operational process of gas chamber, by piston and T baffles move up and down come
Realize the discrepancy of coal gas.But piston and T baffles during moving up and down it is possible that unbalance situation is, it is necessary to pass through
Levelling device hinders the unbalance generation of piston, ensures that the piston of gas chamber remains horizontal in upper and lower operation, and do not produce
Revolution, offset, also ensure that gas chamber is safely and effectively run.
As shown in Fig. 2, being the levelling device schematic diagram of traditional rubber film sealed dry type gas chamber, levelling device includes living
Fill in steel cable fixed frame, leveling steel cable, roof steel rope sleeve cylinder, levelling device platform, pulley platform, piston pulley, counterweight pulley, pulley
Platform rope guide rack, roof steel cable saddle seat, leveling counterweight, leveling weight guide and lower part protection grid；Piston steel cable fixed frame is fixed
On piston, roof steel rope sleeve cylinder is located on cabinet top plate, and leveling weight guide is distributed along on the outside of side plate, and grid are protected along side plate in lower part
Exterior bottom is distributed, and levelling device platform is located on levelling device platform along cabinet top plate edge distribution, pulley platform, pulley platform conductor rope
Frame, piston pulley and counterweight pulley are located on pulley platform, and roof steel cable saddle seat is distributed on cabinet top plate, and leveling steel cable one end is consolidated
It is scheduled on piston steel cable fixed frame, the other end straight up and is pierced by cabinet top plate by roof steel rope sleeve cylinder, then passes around one
Piston pulley on levelling device platform is folded to inner side, is then turned to by roof steel cable saddle seat and is folded to outside, finally bypassed
Counterweight pulley on another levelling device platform is downward in cabinet outside upright, and leveling counterweight is fixed on leveling steel cable and is located at cabinet
One end of external side, leveling weight guide prevent leveling counterweight position to corresponding leveling with position-limiting action, lower part protection grid are restarted
Personnel when lowest point are close, and pulley platform rope guide rack plays the role of the leveling steel cable at pulley platform conductor rope, two leveling
Steel cable shares a leveling counterweight.
Above-mentioned levelling device produces pulling force by leveling counterweight to leveling steel cable, and so as to fulfill the leveling of piston, leveling is drawn
Power is bigger, and levelling effect is better, it is widely used on rubber film sealed dry type gas chamber, but facts have proved it there are following
Defect：With the increase of gas chamber volume and pressure, in order to ensure piston levelling effect, it is necessary to matched somebody with somebody using the larger leveling of weight
Weight, part have weighed 5 to 6 tons, and overweight leveling counterweight fabrication and installation difficulty is also larger, adds engineering construction cost, match
Leveling guide rail of set etc. is also required to maximize, and work is time-consuming and laborious.
The content of the invention
The object of the present invention is to provide it is a kind of reduce rubber film sealed dry type coal gas cabinet leveling balance weight leveling method,
Leveling balance weight needed for this method only needs the half equal to conventional method to can reach same levelling effect.
The technical solution adopted in the present invention is：
A kind of leveling method for reducing rubber film sealed dry type coal gas cabinet leveling balance weight, in the base of original levelling device
On plinth, leveling balance weight is reduced half, accordingly changes small by leveling weight guide size and adds movable pulley, movable pulley steel
Rope, spooler and fixed pulley, two leveling steel cables share a movable pulley, and movable pulley steel cable fixing end coordinates with spooler, moves
Pulley steel cable movable end bypass after fixed pulley straight up, then pass around after movable pulley straight down, leveling counterweight is fixed on dynamic
Pulley steel cable movable end, the keying situation and retractable linear velocity and piston of spooler are chain, and the length of movable pulley steel cable is piston
2 times of stroke.
The beneficial effect of present aspect is：
In order to reach same levelling effect, only need to be equal to conventional method using the leveling balance weight needed for this method
Half, meanwhile, although movable pulley can be laborsaving, using in the case of movable pulley, the operation stroke of leveling counterweight is but
One times more than original scheme, this problem can be by setting spooler is perfect to solve.

Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 3, a kind of leveling method for reducing rubber film sealed dry type coal gas cabinet leveling balance weight, in original tune
On the basis of leveling device, 3 weight of leveling counterweight is reduced half, accordingly changes small by 15 size of leveling weight guide and adds dynamic cunning
Wheel 19, movable pulley steel cable 20, spooler 21 and fixed pulley 22, two leveling steel cables 12 share a movable pulley 19, movable pulley steel
20 fixing ends of restricting coordinate with spooler 21,20 movable end of movable pulley steel cable bypass fixed pulley 22 after straight up, then pass around it is dynamic
After pulley 19 straight down, leveling counterweight 3 is fixed on 20 movable end of movable pulley steel cable, the keying situation of spooler 21 and retractable
Linear velocity and piston 13 are chain, and the length of movable pulley steel cable 20 is 2 times of 13 stroke of piston.
Fig. 4 is the simple mechanical analysis figure of the leveling method and traditional leveling method of the present invention, and left side is traditional leveling side
The simple mechanical analysis figure of method, 3 weight of leveling counterweight are G, then the pulling force that two leveling steel cables 12 are subject to should be equal, and
The pulling force that two leveling steel cables 12 are subject to, which is added, should be equal to 3 weight of leveling counterweight, then F1=G/2；Right side is the tune of the present invention
The simple mechanical analysis figure of quadratic method, leveling balance weight is G/2, simultaneously because the presence of movable pulley 16, with movable pulley steel cable
20 pairs of movable pulleys 19 can also produce a pulling force f, according to steel cable stress equal principle everywhere, f=G/2, then movable pulley 19
The pulling force down being subject to is G, for leveling steel cable 12, pulling force that two leveling steel cables 12 are subject to should it is equal and
Be added and be equal to the pulling force down that movable pulley 19 is subject to, i.e. F2+F2=G, draws F2=G/2.Therefore, in order to reach same tune
Flat effect, the half equal to conventional method is only needed using 3 weight of leveling counterweight needed for this method, meanwhile, although movable pulley
19 can be laborsaving, but using in the case of movable pulley 16, the operation stroke of leveling counterweight 3 but one times more than original scheme,
This problem can be by setting spooler 21 is perfect to solve.
With using 150,000 m of 9 groups of leveling3Exemplified by rubber film sealed dry type gas chamber, its original single group leveling counterweight 3 is 6
Ton, using after levelling device of the present invention, it is necessary to single group leveling counterweight 3 be only 3 tons, only leveling counterweight 3 this i.e.
27 tons of steel can be saved, will be more plus leveling weight guide 15 to match etc..
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
