Description
Technical field
The utility model is related to a kind of performance test apparatus of pipeline, the anti-flexible punching of exhaust duct of more particularly to a kind of house
Hit experimental rig.
Background technology
House exhaust passage is mounted in house kitchen, fume centralized discharge is sent into the cigarette that exterior space is gone in toilet
Chimney, is for excluding the cooking fume of house kitchen cooking activity generation or the nonmetal pipeline product of toilet foul smell.Also referred to as live
Residence exhausting duct, residential ventilation road, house cigarette air channel.House exhaust passage is house kitchen, toilet common exhaust duct system
Chief component.
House exhaust passage construction market extensive utilization, according to standard JG/T194-2004《House kitchen, toilet row
Air flue》Standard requirement, anti-soft impulse：Using whole exhaust duct product as test test specimen, the big face of test specimen is supported horizontally inside offset distance
For on 1.8m wooden rib, the high wide size of wooden rib is 50mm*50mm, and length is more than the cross section length of side of test specimen, uses 10kg normal sands
Bag top 1m distance in the middle part of test specimen is freely fallen, and same position is impacted 5 times, sees whether test specimen ftractures.
At present, the method for the in the market test anti-soft impulse of exhaust duct is all the way according to above-mentioned standard, but is not had also
There is the detection means for meeting above-mentioned standard way, therefore, present method of testing often still holds 10kg sand by testing staff
Bag is being detected, and testing staff can not accurately control the height in 1m, and then make it that the structure of detection is inaccurate.
Utility model content
The purpose of this utility model is to provide a kind of anti-soft impulse experimental rig of house exhaust duct, with can be more
Sand pocket is accurately controlled apart from the height of test specimen, so that the structure of detection is more accurate.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of house exhaust duct
Anti- soft impulse experimental rig, including base and the support frame being arranged on base, the upper end of support frame as described above is provided with connection
Component, the upper end of the connection component is fixedly connected with support frame, and lower end is hinged with a swing rod, and one end of the swing rod passes through rope
Rope is connected with sand pocket, and the other end is connected with the pull rope drawn for testing staff, and one end that the swing rod is connected with rope is pendulum
Dynamic section, the other end is drive section；The wooden rib placed for test specimen, two wooden ribs are provided with the relative both sides of the base
The distance between be 1.8m, be provided with the connection component for positioning swing rod into the keeper of level, the swing rod and rope
One end of rope connection to the distance of connection component is 10cm, and the sand pocket is located above the medium position between two wooden ribs, institute
State the length that one end that swing rod is connected with pull rope is less than or equal to connection component vertical direction to the distance of connection component；
When swing rod and keeper are contradicted, the vertical distance between the wooden rib and sand pocket is 1m.
By using above-mentioned technical proposal, testing staff can support dragline messenger, the drive of swing rod is driven by pull rope
Dynamic section stops traction, by the two ends of test specimen to lower swing when swing rod is horizontal by the restriction effect of keeper
It is placed in wood stupefied, sand pocket is located just at the position of 1m directly over the middle part of test specimen, then remove the pulling force to pull rope, make
Obtaining sand pocket, freely falling body is tested test specimen under gravity；And this process is due to the setting of keeper so that inspection
As long as survey personnel are pulled down by pull rope, untill swing rod can not be continued drop-down by the restriction effect of keeper, now
It is the position that sand pocket is 1m with test specimen distance, so as to accurately control sand pocket apart from the height of test specimen, so that inspection
The structure of survey is more accurate, and this process only needs to a testing staff and can completed, very convenient.

Gravity makes to be not susceptible to skew, and both sides are not susceptible to swing by the clamping action of connecting plate, so that swing rod can
Stable progress is swung, and the position for making sand pocket fall on test specimen is more accurate, and then makes the result of test more accurate.
Further, the length of the swing rod is 3m, and the length of the connecting plate vertical direction is 2m.
By using above-mentioned technical proposal, the length of swing rod is 3m, and wobble segment is 1m, and drive section is just 2m, drive section
Length is swings 2 times of segment length, and according to lever principle, its testing staff only needs to during seeing that 10kg sand pockets are carried upwards
Using 5kg or so pulling force, the force of testing staff is greatly reduced, and then reduces the labor intensity of testing staff.
Further, the keeper is the L-shaped spacer of cross sectional shape, and one end and the connecting plate of the spacer are consolidated
Fixed connection, the other end extends to one end away from sand pocket, and the spacer is horizontally disposed with；
When swing rod is horizontal, the downside of the spacer and drive section is contradicted.
By using above-mentioned technical proposal, set what can be stablized to limit drive section by spacer, and then
The effectively accurate positioning of progress is horizontal to swing rod, so that the distance between sand pocket and test specimen are more accurately positioned at
1m, so that the structure of detection is more accurate.
Further, the keeper is locating rod, and one end of the locating rod is fixedly connected with support frame, and the other end is erected
Directly extend downwardly；
When swing rod is horizontal, the lower end of the locating rod and the upside of wobble segment are contradicted.
By using above-mentioned technical proposal, the setting of locating rod can be positioned to wobble segment, and then swing rod is in
Horizontal level carries out effectively accurate positioning, so that the distance between sand pocket and test specimen are more accurately positioned at 1m, so that inspection
The structure of survey is more accurate.
Further, position corresponding with support is provided with mounting cylinder on the base, and the lower end of support frame as described above is penetrated
Into mounting cylinder, the bolt for fixing support rack is threaded with the side wall of the mounting cylinder.
By using above-mentioned technical proposal, the setting of mounting cylinder can realize the dismounting between base and support frame, so that
Whole device is dismantled, can be taken apart when not in use, the occupancy in space is reduced.
Further, the base, support frame, connecting plate, swing rod are made by zinc-plated square tube.
By using above-mentioned technical proposal, base, support frame, connecting plate, swing rod are made by zinc-plated square tube, can be subtracted
The weight of light whole device, it is easy to which testing staff's moves.
In summary, the utility model has the advantages that：
By the setting of swing rod and keeper the distance between sand pocket and test specimen more can accurately be controlled；
The length that segment length is less than drive section is swung, the labor intensity of testing staff is reduced using lever principle；
The dismounting of base and support frame support can be realized by the setting of mounting cylinder, the occupancy in space is reduced.
