The purpose of this utility model is to design a kind of test pavement simulating fatigue tester, and its test condition can be simulated at high temperature, the test under low temperature and the damage by water evil environmental baseline, and the loaded load adjustable size, loading frequency is adjustable, and stroke is long, and the even stand under load of test specimen.
Technical solution of the present utility model is a kind of road surface comprehensive simulation fatigue tester, an adjustable charger of activity of being installed by the workbench that test specimen is installed and its top constitutes, movable adjustable charger is to be connected jointly to load to take turns with vertical lifting mechanism by horizontal reciprocating movement mechanism to constitute, and there is spray water logging circulating device the workbench top.Refrigeratory is housed in the testing machine.Testing machine and machine external pelivimetry instrument are used in combination, and the test specimen that is loaded on the testing machine attaches sensor, and sensor and measuring instrument electrically connect, and the electric instrument that sensor produces number is connected to the power strainmeter of measuring instrument, receives display screen and printer more respectively.Description of drawings is as follows:
Fig. 1 is the moving web wheel mark formula test pavement simulating testing machine structure signal of prior art
Fig. 2 is the utility model road surface comprehensive simulation fatigue tester structural representation
The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:
A kind of road surface comprehensive simulation fatigue tester, an adjustable charger of activity of being installed by the workbench that test specimen is installed and its top constitutes, movable adjustable charger is to be connected jointly to load to take turns with vertical lifting mechanism by horizontal reciprocating movement mechanism to constitute, there is spray water logging circulating device the workbench top, and refrigerator is arranged in the testing machine.Testing machine and machine external pelivimetry instrument are used in combination, the test specimen that is loaded on the testing machine attaches sensor, sensor and measuring instrument electrically connect, measuring instrument comprises the power strainmeter, display screen and printer, the electric signal that sensor produces is received the power strainmeter through the electric bridge box, is connected to display screen and printer more respectively.
The horizontal reciprocating movement mechanism of its movable adjustable charger is: loading seat [1] is gone up motor [2] is installed, connection turns to change speed gear box [3], chain pitch wheel gear train [4], its final stage gear gear mesh of coaxial connection [25] successively, in-line gears mesh with two parallel gears bars [6] that level is installed respectively two gears of [25], and side roll is connected with tooth bar [6] with guide wheel [14], pressing head seat [1] is gone up dress and is loaded weights [5] and load wheel [16].
The vertical lifting mechanism of its movable adjustable charger is: two parallel racks [6] two ends mat guide wheels [12] that level is installed connect with 4 vertically arranged guide rails [8], connected with parallel rack [6] two ends respectively by hinge rope [9] the mat leading block group [7] that is fixed on the reel [11] in addition, reel [11] axle head is equipped with rotation rocking handle [10].
Its spray water logging circulating device is: worktable [23] is an on-swimmer's pool, its lower link water storage tank [18], and have little duct to be communicated with it, water storage tank [18] mat connecting pipe [20] and water pump [21] and place the shower [15] of worktable on-swimmer's pool [23] top to connect successively to be communicated with.
A refrigerator is housed in the testing machine, connects formation with the refrigerator [22] of workbench below by the cooling tube [24] that places the workbench top.
Well heater also is housed on the workbench, constitutes with placing the flat ripe pipe of calcium carbide English [13] of doing the platform top by the electric heater that places on-swimmer's pool [23] [17].
