Therefore, the inventor develops a kind of bridge pad pressure-shear test machine through research, and this case produces thus.
Summary of the invention
The purpose of the utility model is to provide a kind of bridge pad pressure-shear test machine, can realize that all events of large-tonnage bridge pad mechanical property detects.
To achieve these goals, the technical scheme of the utility model is following:
A kind of bridge pad pressure-shear test machine comprises base, hydraulic system, bogey; Shear arm-tie and detachable extension rod, bogey comprises moving beam, and moving beam is installed on the slide bar; Be followed successively by loading plate under the moving beam, rotary corner plate and following loading plate, following loading plate is positioned on the base; Hydraulic system comprises the main frame piston, horizontal hydraulic pressure top and vertical hydraulic top, and wherein the main frame piston is arranged in base; Shearing arm-tie links to each other to ram with level; Be positioned at same horizontal level with following loading plate, detachable extension rod links to each other to ram with vertical, under the end of corresponding rotary corner plate; After bearing system is reinforced sample, through shearing arm-tie and detachable extension rod come mechanical property from test sample to the sample application of force.
Further, the four corners position of moving beam also is equipped with four grating displacement sensors.
Further, also comprise three electrohydraulic servo valves in the hydraulic system.
Further, level is connected with load sensor to ram.
Further, vertically be connected with load sensor to ram.
Further, under the following loading plate pulley is housed.
After adopting such scheme, the utility model compared with prior art has the following advantages:
Through adopting the large-tonnage hydraulic system that test loading force source is provided, can be simultaneously to pressing, cuts, change test power to test, and the vertical test power of adjustment compensation is automatically effectively improved the standard to loading or detection performance during corner test loading.

[embodiment]
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
A kind of bridge pad pressure-shear test machine as shown in Figure 1, that the utility model discloses comprises base 1; Hydraulic system, bogey is sheared arm-tie 231 and detachable extension rod 221; Bogey comprises moving beam 31, and moving beam 31 is installed on the slide bar 35, and moving beam is followed successively by loading plate 32 31 times; Rotary corner plate 34 and following loading plate 33, following loading plate 33 is positioned on the base 1; Hydraulic system comprises main frame piston 21; Level to ram 23 with vertical to ram 22; Wherein main frame piston 21 is arranged in base 1, shears arm-tie 231 and links to each other to ram 23 with level, is positioned at same horizontal level with following loading plate 33; Detachable extension rod 221 links to each other to ram 22 with vertical, under the end of corresponding rotary corner plate 34.Wherein descend loading plate 33 and rotary corner plate 34, go up between loading plate 32 and the rotary corner plate 34 and all can lay sample 5, further, following loading plate 33 is equipped with pulley 331, can be used for sample 5 is transported on the base 1.
