Description
Technical field
Fire fighting extinguisher is mutually rescued between adjacent opposite high-rise building
Technical background
Be used in the fire fighting truck of high-rise building fire-fighting fire extinguishing now and Patent Office, State Intellectual Property Office announce on the net it is special
" vertical and horizontal triangle is suspended vacantly the hard fire extinguisher canvas hose that outer wall has transverse serration " that benefit number is 201410123769.2.
Summary of the invention
The fire fighting truck for the high-rise building fire extinguishing disaster relief used now is by truck, water tank, battery or power generation
Machine, motor, high-pressure hydraulic pump are hydraulic to open the drop components such as equipment and canvas rubber water pipe composition.I only takes its fire extinguisher canvas hose
One, original canvas rubber water pipe is transformed into the one section one section hard water pipe connected.The section of hard water pipe and section it
Between the shapes and sizes size of interface that is connected it is identical with the interface of the canvas rubber water pipe used now.With neighbouring opposite
The high building not caught fire is to rely on, and is fixed with multiple skew cables and this root hard fire extinguisher canvas hose of load-bearing in vertical direction；In level
Direction positions this root hard fire extinguisher canvas hose with cable traction, to complete the three-dimensional suspension frame of this hard fire extinguisher canvas hose
If.The script that connection uses now in the front end of this hard fire extinguisher canvas hose is connected to the water spray of canvas rubber fire extinguisher canvas hose front end
Mouthful, the canvas rubber fire extinguisher canvas hose that rear end connection uses originally is connected to each floor inside the high building not caught fire so as to support
On any one interior original fire hydrant, succoured with the water source of fire hydrant in the high building not caught fire put out it is adjacent opposite another
The fire of building high building.The hard fire extinguisher canvas hose of slotted guiding round buss and single-end the cooperation push of present patent application is this
A component in design scheme.This component is referred to as hard fire extinguisher canvas hose.This be with " vertical and horizontal triangle is suspended vacantly outer wall
Having the hard fire extinguisher canvas hose of transverse serration " different instruments realizes the design scheme of same purpose.
Because my this technology be derived from that State Patent Office announces on the net entitled " vertical and horizontal triangle is hanging
Fixed outer wall has the hard fire extinguisher canvas hose of transverse serration ", so both technologies have identical ground difference.
First have a talk about identical place:
One, hard fire extinguisher canvas hose and suspension cable traction rope, slotted guiding round buss and single-end cooperation push
Mechanical device, suspension cable capstan winch, water jet, after the components such as canvas rubber water pipe gather together enough, and the high building not caught fire with a building
To rely on, and it is with geometry triangle stability principle suspension cable and traction rope that hard fire extinguisher canvas hose therein is vacantly solid
Get up calmly, forms an aerial water stream channel.In the Figure of description 1 of 201410123769.2 scheme of Patent No., attached drawing 2
In it is stated that not being the new content of this scheme, no longer attached drawing.
Two, must equally be the fire extinguisher canvas hose of hard, otherwise either pushed out with mechanical force or with suspension cable and
Traction rope is suspended vacantly all without impetus.
Three, interface.In order to equipment such as the fire extinguisher canvas hoses used on this newly-designed hard fire extinguisher canvas hose and current society
It is connected, the shape and size of interface are the same.Shape is the same, is all the double sides for buckleing built-in rubber gasket of double sliding slots
Formula；Size be it is the same, the outer diameter of tube wall is 110 millimeters, tube wall with a thickness of 16 millimeters；This is others' technology, not at this
The technical scope that people this time applies, so not drawing its figure and size one by one.
Or interface four,.The fracture of hard fire extinguisher canvas hose interface in order to prevent, the connected hard fire water of whole root segment section
The interface of pipe is other than the interface that front end connection water jet connects at canvas rubber water pipe with rearmost end, all section Duan Xianglian
Interface all use 3 teeth in " vertical and horizontal triangle is suspended vacantly the hard fire extinguisher canvas hose that outer wall has transverse serration " this technical solution
The interface of the screw-type of (1080 degree of circumference).This is the scheme announced on the net, is not the technical solution of this application, so also not
Its figure and size are drawn one by one.The spacing of screw thread, thickness, width are all that need to be planned as a whole to calculate in conjunction with the intensity of making material
And modular in design.
Besides say difference:
I carries out the transverse serration of the outer wall of " vertical and horizontal triangle is suspended vacantly the hard fire extinguisher canvas hose that outer wall has transverse serration "
Another has the design for taking house.Whole hard fire extinguisher canvas hose outer wall ring by ring ring by ring is successive from the beginning to the end
Circumference layout transverse serration be transformed into only 360 degree of the circumference transverse serrations for being similar to 1/20 radian, remaining is similar to 19/
20 transverse serration is all given it up.This short transverse serration is along whole
A slotted guiding round buss is done again entangles hard fire extinguisher canvas hose.19 millimeters of arc length of the width of slot than transverse serration
Somewhat larger, there are about 0.5-1 millimeters of gaps.The direction of slot is longitudinal direction and the same side of hard fire extinguisher canvas hose of round buss
To the i.e. rack gear same direction with hard fire extinguisher canvas hose outer wall.The connected outer wall of whole root segment section has the hard fire extinguisher canvas hose of rack gear
Push can be arbitrarily moved forward and backward in slotted guiding circle guide tube.It is 16 millimeters that the wall thickness of round buss, which is fixed tentatively, round buss
Internal diameter is 111 millimeters (gap for leaving 1 millimeter), and outer diameter is 143 millimeters.It is using the self-locking electricity of lifting as the power of push
Worm gear that the gear (gear with a thickness of 18 millimeters) that motivation drives is also possible to be engaged with electronic worm screw (worm gear with a thickness of
18 millimeters) it is engaged with the rack gear of hard fire extinguisher canvas hose outer wall to transmit power.This is that the outer wall form of another design method is complete
Complete different hard fire extinguisher canvas hose and another matched gear pusher.I is referred to as it to call " slotted guiding circle
The hard fire extinguisher canvas hose of sleeve and single-end cooperation push ".In order to make the sturdy occlusion of rack and pinion, a little arc
The groove of degree (20 degree) is made into the groove fan-shaped outer arc cut-off.The width of rack gear is about 18 millimeters, and (each of these segment is horizontal
About 19 millimeters of groove arc length, about 18 millimeters of the linear distance of outer arc two-end-point).The spacing of groove is 15 millimeters.The thickness of groove
It is 5 millimeters.Because there is this to design, the push power of the rack gear of gear mesh hard fire extinguisher canvas hose outer wall is strengthened.Original
It is that hard fire extinguisher canvas hose is clamped with the gear of two corresponding horizontal settings in 201410123769.2 design, turning gear
Wheel transmitting power；And the technology of this secondary design is to be placed in the direct geared below hard fire extinguisher canvas hose and withstand on hard fire-fighting
Under water pipe, the occlusion up and down that rack and pinion is vertically oriented, the own wt of hard fire extinguisher canvas hose is directly born against on gear.Examination
Think, if clamping the square of a twenty or thirty kilogram with two palms, power used is the friction between palm and square
Power, it is relatively elaborate, if curving finger, under tetragonal body face handle it hold, can lift easily, used has eaten.
This is the direction for comparing the active force between two kinds of design middle gears and hard fire extinguisher canvas hose, presss from both sides a hard with two gears
The power that fire extinguisher canvas hose is acted on is to decompose, and withstanding the power that hard fire extinguisher canvas hose is acted on single gear is eating for concentration
?.There are also the differences of stress point.In original 201410123769.2 design, biting point is outside hard fire extinguisher canvas hose
It is two on circle (gear) and tangent line (hard fire extinguisher canvas hose) on the contact point of wall and two gears of horizontal direction placement
Point of contact；And in the design, biting point is on the contact point of the rack and pinion on hard fire extinguisher canvas hose outer wall, because on rack gear
About 20 degree of fan-shaped radian is by cut-off, so biting point is actually a lines of occlusion, transmission dynamics is increased.
This hard fire extinguisher canvas hose is preferably big with intensity, good toughness, plastics manufacture resistant to high temperature.Model batch can be made to be perfused
Manufacture is to reduce cost.Slotted guiding round buss is advisable with steel or aluminium alloy manufacture.
The advantages of this new Technology design:
1. protecting root.So-called root is the place that gear is engaged with hard fire extinguisher canvas hose, stablizes complete equipment
Impetus.If suspension cable fracture or suspension cable launch it is too long and make hard fire extinguisher canvas hose tenesmus bending it is excessive when, be here
It is easiest to fracture.Have a package of round buss, the root of hard fire extinguisher canvas hose, which is equal to, a sheath, have one section it is curved
The elastic space of song deformation.This cans be compared at the electric pole landing that the diameter for being to set by road is about 30 centimetres, outside electric pole
Wall has wrapped up the concrete that a loop diameter is about 60 centimetres, and it is to prevent that electric pole from being hit and root fractures that reason, which is the same,
It is necessary.Because there is the package of round buss, the position of hard fire extinguisher canvas hose up and down is all limited, rack and pinion
Occlusion more closely, driving force is adequately transmitted；Because there is round buss, like movement of the bullet in gun barrel,
The transmitting for pushing the power of hard fire extinguisher canvas hose is more concentrated, and direction is more acurrate, rather than as beating stone with catapult, stone is gone out
Route be the camber line to move swiftly.
2. because there is guiding round buss, more conducively hard fire extinguisher canvas hose angle control in the horizontal direction.
It in addition to this, is the state for the rack gear of hard fire extinguisher canvas hose outer wall being adjusted to a straight line, in hard fire water
The rubber washer for the interface that pipeline section is connected with section suitably thickeies, for example increases to 5 millimeters, empty with the elasticity for increasing rubber washer
Between.
