Description
Technical field
The present invention relates to fire-fighting supporting tool field, especially a kind of Multifunction open bolt device.
Background technique
Fire hydrant is the tie connected between extinguishing chemical and fire extinguisher canvas hose, and when being put out a fire, fire fighter passes through opening
Valve operation lever on fire hydrant, to make the Fire branch spray of extinguishing chemical on hand from fire hydrant, fire hose, fire fighter
Out to being put out at fire.Currently, controlling the stem movement of hydrant valve in fire-fighting domain, and then open fire hydrant internal valve
The mode of core is the valve rod upper end operation panel or operation handle directly operated by fireman positioned at hydrant valve, and then beats
The spool of fire hydrant is opened, but the strength that the spool due to opening fire hydrant needs to apply is larger, it is therefore desirable to be equipped with longer behaviour
Make handle and be relatively large in diameter operation panel, in order not to too long and operation panel be relatively large in diameter to periphery passerby, vehicle because of operation handle
By impacting, and in order to prevent, irrelevant personnel is used, therefore existing fire hydrant is generally unworthy of on the valve rod of valve
Standby operation panel or operation handle, when generation fire needs to put out a fire, fire fighter opens hydrant valve upper end with specific purpose tool
Valve rod, and then fire hydrant spool is opened, and extinguishing chemical sprays, to putting out a fire at fire.
It is existing to open bolt tool, that is, opening the tool of fire hydrant spool is usually monkey wrench, pipe wrench or solid wrench.
Since the valve rod shape of hydrant valve is all kinds of, existing hexagon, square, rectangle, there are also a rear and front end straight line left sides
The structure of right both ends arc, thus to scene after, if operated using adjustable wrench or pipe wrench, need to adjust Flexible spanner repeatedly
The bayonet of hand or pipe wrench makes the valve rod shape of bayonet and hydrant valve coincide, thus in subsequent rotation valve rod upper end as far as possible
When can facilitate force；In this case, since the valve rod for needing to adjust bayonet and valve repeatedly coincide as far as possible, in practical application
Have the shortcomings that adjustment speed is slow；Moreover, because fire hydrant generally require large force could open, monkey wrench and pipe wrench
It is not easy to adjust between bayonet position and valve rod and extremely coincide, therefore when operation movable wrench or pipe wrench open spool, is easy
Slipping phenomenon is generated, then leads to not rotation valve rod, the spool of fire hydrant can not be opened, cause attack time to be delayed, cause
More serious net fire effect.Existing fire hydrant solid wrench only has an opening, can only meet a kind of hydrant stem
It opens and needs, therefore exist and use limitation.
Summary of the invention
In order to overcome what existing fire hydrant used to open bolt tool because structure limits the drawbacks of bringing, the present invention provides one kind
With certain length (general 1 meter or so), convenient for users to opening the valve rod force of fire hydrant, but also there are a variety of openings,
Opening shape covers the valve rod shape of existing fire hydrant, and in fire extinguishing, fire fighter can be according to the shape of valve rod quickly by phase
Bayonet is answered to cover in valve rod upper end, to save the position aligning time between tool and valve rod, and due between opening and valve rod
Shape is coincide, and the more efficient application active force of operator's energy is in valve rod, and then spool can be opened within a short period of time, fire fighter
It is put out a fire in time using the extinguishing chemical sprayed through fire hydrant, gains time, fire damage is reduced to most much lower for fire extinguishing
Function opens bolt device.
The technical solution adopted by the present invention to solve the technical problems is：
Multifunction open bolt device, it is characterised in that including operating stick, operating head, operating stick and operating head are integrally formed, operation
Bar and operating head are steel materials, and two operating heads are located at the both ends of operating stick, and in left end, the outermost of operating head has one
A hexagonal screw rod opens half bayonet used, and the right end of half bayonet of left end operating head has the full bayonet of hexagonal screw rod, in right end
The outermost of operating head has a square screw rod to open half bayonet of square used, half bayonet of square of right end operating head
There is a complete square bayonet in left end, is laterally respectively provided with one from left to right in the operating stick for being located at right end operating head left part
The full bayonet of square, disparate shape bayonet, the rectangular bayonet of overall length of rear and front end straight line left and right ends arc.
The left end operating head outermost hexagonal screw rod opens its internal diameter of half bayonet used and is greater than left end operating head hexagonal
The full bayonet internal diameter of screw rod.
The outermost square screw rod of the right end operating head opens its internal diameter of half bayonet of square used and is greater than right end
Operating head square bayonet internal diameter entirely.
Its internal diameter of bayonet is less than the square in the operating stick of right end operating head left part laterally from left to right entirely
Right end operating head square bayonet internal diameter entirely.
The upper-lower height one of the square in the operating stick of right end operating head the left part full bayonet and disparate shape bayonet
It causes.
Described its height of the rectangular bayonet of overall length in the operating stick of right end operating head left part is lower than the height of disparate shape bayonet
Degree.
Present invention has the advantages that：Length of the present invention is grown to be acted at one meter, overcomes existing hydrant stem opener
The short practical operation of length in force it is inadequate, it is also necessary to steel pipe etc. in the back-end operations rod set of opener, increase is applied to
The drawbacks of hydrant stem active force.The present invention combines existing main hydrant stem shape, in operating stick, a left side for operating head
Right both ends are provided with corresponding hexagonal screw rod and open the full bayonet of half bayonet, hexagonal screw rod used, square half bayonet, full pros
Shape bayonet, square full bayonet, disparate shape bayonet, the rectangular bayonet of overall length, various bayonets cover the valve rod shape of existing fire hydrant
Shape.When being put out a fire, since the present invention has certain length, so that the person of being convenient to use opens the valve rod force of fire hydrant, by
In with a variety of openings, in fire extinguishing, fire fighter quickly can cover corresponding bayonet in valve rod upper end according to the shape of valve rod, from
And save the position aligning time between tool and valve rod, and due between opening and valve rod shape coincide, operator can be more
Effectively apply active force in valve rod, and then spool can be opened within a short period of time, fire fighter uses goes out through what fire hydrant sprayed
Fiery agent is put out a fire in time, is gained time, fire damage is reduced to minimum for fire extinguishing.Based on above-mentioned, so the present invention has
The application prospect having had.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
