A kind of interface tension test unit, comprise telescopic testing table support, it is characterized in that: on described testing table support, be provided with drive unit, the piston rod of drive unit is arranged on testing table support, piston rod is connected with S type pulling force sensor upper end by the first coupling shaft, and S type pulling force sensor lower end is connected with survey dish by the second coupling shaft; Described S type pulling force sensor is connected with computer with data collecting card.
Described a kind of interface tension test unit, is characterized in that: described drive unit comprises the air compressor, pneumatic triple piece, solenoid valve and the pneumatic cylinder that connect successively; Wherein pneumatic cylinder is connected with the first coupling shaft.
As preferred version, described a kind of interface tension test unit, is characterized in that: the material of described survey dish and coupling shaft is No. 45 steel.
As preferred version, described a kind of interface tension test unit, is characterized in that: described testing table support is iron material matter.
Beneficial effect: a kind of interface tension test unit that the utility model provides, adopt combined type survey dish, can guarantee that survey dish vertically pulls open from soil surface, adopt again pneumatically loading to guarantee to load evenly continuously; Can realize simple measurement soil adhesion, and simple in structure, and testing table support can stretch, can change different survey dishes, cost of manufacture is low, easy to operate, can complete soil adhesion force measurement and interface tension test, facility visbreaking takes off native research, significant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The implication of Reference numeral in figure: 1 pneumatic cylinder, 2 testing table supports, 3 first coupling shafts, 4 is S type pulling force sensor, 5 second coupling shafts, 6 survey dishes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of interface tension test unit, comprise telescopic testing table support 2, on testing table support 2, be provided with drive unit, the piston rod of drive unit is arranged on testing table support 1, piston rod is connected with S type pulling force sensor 4 upper ends by the first coupling shaft 3, and S type pulling force sensor 4 lower ends are connected with survey dish 6 by the second coupling shaft 5; Described S type pulling force sensor 4 is connected with computer with data collecting card.
Described drive unit comprises the air compressor, pneumatic triple piece, solenoid valve and the pneumatic cylinder 1 that connect successively; Wherein pneumatic cylinder 1 is connected with the first coupling shaft 3.
As preferred version, described a kind of interface tension test unit, is characterized in that: the material of described survey dish 6 and coupling shaft 3,5 is No. 45 steel.
As preferred version, described a kind of interface tension test unit, is characterized in that: described testing table support 2 is iron material matter.
Principle of work of the present utility model is as follows: when work, air compressor provides pressure, obtains evenly continuous pressure by three linked piece and solenoid valve, and air pressure vertically acts on pneumatic cylinder 1, drives piston rod to move up and down; And drive S type pulling force sensor 4 to move by the first coupling shaft 3, and drive survey dish 6 to move up and down by the second coupling shaft 5, realize soil adhesion force measurement and interface tension test; Wherein, S type pulling force sensor 4 is converted into voltage signal by the pulling force recording and is transferred to collection and preservation in computer by data collecting card.For convenience of experimental implementation, testing table support 2 can stretch, for the replacing of survey dish is provided convenience.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
