Description
Technical field
This utility model relates to Cohesion torque test instrument, is specifically related to the on-the-spot quickly inspection of a kind of cohesive strength
Survey tester.
Background technology
Along with temperature raises, the adhesive aggregation force value of Colophonium reduces, and deformability strengthens.Work as temperature
Reducing, compound cohesive strength can be made to improve, intensity increases, and deformability reduces.But temperature mistake
Low meeting makes asphaltic road-mix surface course ftracture.Owing to loading frequency is high, asphalt can be made to produce
Excessive stress and plastic deformation, elastic return is very slow, produces expendable permanent deformation,
When road surface completes, road pavement to carry out cohesive strength test.
Existing Cohesion torque test is only capable of carrying out slurry seal in laboratory conditions, micro-surface area becomes
The test of type speed, it is impossible to be applied to job site.
The indenter size of existing Cohesion torque test is fixed, and the uniformity of compound is to result of the test
Have a significant impact.In the case of compound uniform in shaping, pressure head is pressed under the influence of air pressure
Sample certain depth, pressure head is relatively big with the contact area of sample, and pressure head is easy in rotary course
By the inhibition of larger particles in relatively bulk specimen, the result of test is bigger than normal, and at compound
In the case of uniformity is not good enough, pressure head easily withstands on bigger granule, easily exists in twist process
Specimen surface skids, and causes result of the test less than normal.
Existing Cohesion torque test uses manual hand manipulation's torque wrench, is only capable of testing single gas
The single torque value of pressure, and test result can not preserve.
Utility model content
For the problems referred to above, this utility model aims to provide one can the most quickly test molding speed
Degree, there is multiple indenter size, there is bigger pressure limit, have and automatically record data function
Cohesive strength field quick detection tester.
For realizing this technical purpose, scheme of the present utility model is: a kind of cohesive strength is on-the-spot quickly
Detection tester, including base and bracing frame, support frame as described above is arranged on above base two ends,
Being provided with top board on support frame as described above, be fixedly installed cylinder under described top board, described cylinder is even
Being connected to support platform, described support platform is connected with test platform, described test by expansion link
Platform connects motor, is provided with dowel steel, below described dowel steel below described test platform
It is provided with dismountable pressure head；
Described top board is further fixedly arranged on pneumatic control components, and described pneumatic control components passes through gas
Pipe connects cylinder, and support frame as described above is fixedly installed automatic reading device, described automatic reading
Device connects pneumatic control components.
As preferably, two ends, described base left and right are also respectively provided with bearing, below described base
It is provided with roller.
As preferably, described bearing connects base by connecting rod, and described connecting rod is scalable
Structure.
The beneficial effects of the utility model, device volume is little, lightweight, and carrying is flexible, cost
Low, easy to use, can truly reflect on-the-spot slurry seal and the shaping speed of micro-surface area, it is simple to
Testing inspection and scientific research use；Whole test process can be automatically performed at the scene, it is not necessary to manually grasp
Make；Instrument is furnished with roller, it is not necessary to lift, and meets the needs of field quick detection；Can also enter
Cohesive strength under row different pressures, different indenter size is tested, and instrument can retain whole test
The data of process also show image, meet follow-up in-depth analysis and scientific research requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
As it is shown in figure 1, specific embodiment described in the utility model is that a kind of cohesive strength scene is fast
Speed detection tester, including base 1 and bracing frame 2, support frame as described above 2 is arranged on base 1
Above two ends, support frame as described above 2 being provided with top board 3, described top board is fixedly installed for 3 times
Cylinder 4, described cylinder 4 connects support platform 5, and described support platform 5 is by expansion link 6 even
Connecing and be provided with test platform 7, described test platform 7 connects motor 8, described test platform
It is provided with dowel steel 9 below 7, below described dowel steel 9, is provided with dismountable pressure head 10；
Described top board 3 is further fixedly arranged on pneumatic control components 11, described pneumatic control components
11 connect cylinder 4 by trachea 12, and support frame as described above 2 is fixedly installed automatic reading dress
Putting 13, described automatic reading device 13 connects pneumatic control components 11.Device volume is little,
Lightweight, carrying flexibly, low cost, easy to use, can truly reflect on-the-spot slurry seal and
The shaping speed of micro-surface area, it is simple to testing inspection and scientific research use；Can be automatically performed whole at the scene
Individual test process, it is not necessary to manual operation；Can also carry out under different pressures, different indenter size
Cohesive strength test, and instrument can retain the data of whole test process and show image, meets
Follow-up in-depth analysis and scientific research requirement.
On-the-spot test for convenience, described base about 1 two ends are also respectively provided with bearing 14,
Described base 1 is provided below roller 15.Instrument is furnished with roller, it is not necessary to lift, and meets existing
The needs of field quickly detection；Described bearing 14 connects base 1, described company by connecting rod 16
Extension bar 16 is bendable structure.During Site Detection, roller is packed up, by seat supports；Detection
Complete, bearing is packed up, and relies on roller to advance.
The above, preferred embodiment the most of the present utility model, not in order to limit this practicality
Novel, every according to technical spirit of the present utility model, above example is made any trickle
