Certain hardness, can ensure the basic service life of road.The design of existing road New Hardness Testing Device is complicated, using rising
Come very bothersome, and be difficult maintenance after damage.
Utility model content
Technical problem to be solved in the utility model is that there is provided a kind of structure the problem of presence for above-mentioned prior art
Simply, easy to use, the easy new road rigidity detection device of maintenance.
The purpose of this utility model is achieved in that a kind of new road rigidity detection device, it is characterised in that：Bag
Pressure cone, spring, pedal, support bar, handle are included, the spring, support bar are symmetrically fixed on the two ends at pedal centre, and spring is not
It is fixedly connected with one end that pedal is fixed with pressure cone, one end that support bar is not fixed with pedal is fixedly connected with handle；The pressure
That bores is shaped as cone, and scale is carved with the side of pressure cone.
The pedal is shaped as disc.
The cone angle of the pressure cone is 60 °.
The pressure cone, spring, pedal, support bar, handle are by the stainless steel making that the trade mark is 1Cr18Ni9, pressure cone, bullet
It is welded to connect between spring, pedal, support bar, handle.
The support bar is cylindrical support bar.
The spring is cylindrical screw shape spring.
The utility model simple, manufacturing rational in infrastructure is easy, easy to use, passes through the utility model, new road
Rigidity detection device includes discoidal pedal, and pedal one end center is connected with the support bar of cylinder, and support boom end is consolidated
Surely there is handle, pedal other end center is connected with cylindrical screw shape spring, and spring end is connected with the pressure cone of cone, pressure cone
Cone angle be 60 °, and pressure cone side be carved with scale.Beneficial effect using above technical scheme is：The new road hardness
Detection means can be first placed on standard road surface when in use, and the weight of specified wt is put on pedal, force pressure cone head
It is expressed to standard road road surface bottom, and records and push coning and enter depth under pavement of road.Pressure cone is placed on again tested
On road surface, the weight of specified wt is put on pedal, forces pressure cone head to be expressed to tested road road surface bottom, record is pushed
Coning enters the depth under pavement of road, and compared with the depth that standard road surface presses under cone insertion road surface, just can measure tested
The hardness on road surface, measures simple and convenient, and the new road rigidity detection device is sturdy and durable.
To sum up, the utility model, when in use, connects pedal by spring and pressure is bored, by the way that weight or human body are pushed down
Pedal, by pressure cone press-in road surface, the depth on viewing pressure cone press-in road surface carrys out the hardness of measurement road, measures simple and convenient, firm
It is durable.
Brief description of the drawings
Fig. 1 is a kind of front view of new road rigidity detection device of the utility model；
Fig. 2 is a kind of left view of new road rigidity detection device of the utility model.
In figure, 1 pressure cone, 2 springs, 3 pedals, 4 support bars, 5 handles.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1 and Fig. 2, a kind of new road rigidity detection device, the new road rigidity detection device includes disk
The pedal 3 of shape, one end center of pedal 3 is connected with the support bar 4 of cylinder, and the end of support bar 4 is fixed with handle 5, the side of handle 5
Just user grips.The other end center of pedal 3 is connected with cylindrical screw shape spring 2, and spring 2 has power stretch, the end of spring 2
Portion is connected with the pressure cone 1 of cone, and the cone angle of pressure cone 1 is 60 °, and scale is carved with the side of pressure cone 1.Pressure cone 1 has higher
Hardness, can be pressed into road bottom after being stressed, and spring 2 can improve the weight capacity of whole new road rigidity detection device.
In the present embodiment, pressure cone 1, spring 2, pedal 3, support bar 4, handle 5 are by the stainless steel that the trade mark is 1Cr18Ni9
Manufacture, not only with good decay resistance, and comprehensive mechanical property is good, and elasticity is big.Pressure cone 1, spring 2, pedal 3,
By being welded to connect between support bar 4, handle 5, connection fastening is not easy to break.
The new road rigidity detection device can be first placed on standard road surface when in use, handle 5 is held, by specified weight
The weight of amount is put on pedal 3, forces pressure cone 1 to be expressed to standard road road surface bottom, and record pushes 1 inlet channel of cone
Depth under the road surface of road.Pressure cone 1 is placed on tested road surface again, handle 5 is held, the weight of specified wt is put in pedal 3
On, force pressure 1 tip of cone to be expressed to tested road road surface bottom, record pushes cone 1 into the depth under pavement of road, and with
The depth that standard road surface pressure cone 1 is inserted under road surface compares, and just can measure the hardness on tested road surface, although measurement accuracy is not high,
But can compare quickly tested road surface and standard road surface hardness who big who is small.The new road rigidity detection device is measured
It is simple and convenient and sturdy and durable.
The above is only preferred embodiment of the present utility model, it is noted that for one of ordinary skill in the art
For, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this
The protection domain of utility model.
