Background technology
For a long time; For solution be embedded in underground various pipelines because of earthquake, temperature variation, soil property is soft and external force load etc. causes pipeline unstable, so large deflection expansion joint demand heightens the factory of production large deflection expansion joint; In order to make product in actual use; Can embody the flexible and off normal function of self, require before product export, must do the flexible of expansion joint and off normal test in theory, but since the band pressure condition down the simulation actual condition do flexible and off normal is tested; Difficulty is very big; It is very high to drop into hardware cost, so the producer of the expansion joint of production large deflection in the market is the voltage-withstand test of housing itself to the test of product, and performance that can not the full test expansion joint.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of testing cost low for the defective that overcomes above-mentioned prior art existence, and is simple to operate, and can simulate actual condition and under the band pressure condition, making large deflection expansion joint proving installation flexible and the off normal test.
The purpose of the utility model can realize through following technical scheme:
A kind of large deflection expansion joint proving installation is characterized in that, this device comprises the base that tries the water, fixedly end face baffle plate, pull bar, horizontal scale table, slide assemblies, intermediate support, middle baffle plate, vertical scale table, vertical oil hydraulic cylinder, pillar and hand member; The described base that tries the water is arranged on this device lower end, and described fixedly end face baffle plate is provided with two, is separately fixed at the two ends of the base that tries the water; Described pillar is provided with four, is separately positioned on the fixedly outside of end face baffle plate, and described pull bar is fixed on fixedly on the end face baffle plate through pull-rod nut; Described horizontal scale table is arranged on the pull bar; Described slide assemblies is arranged on the horizontal rail of the base that tries the water, and described intermediate support is fixed on the slide assemblies, and described middle baffle plate places on the intermediate support; Described vertical scale table is arranged on the middle baffle plate; Described vertical oil hydraulic cylinder places the below of middle baffle plate, and its upper end is connected on the middle baffle plate, and the lower end is connected on the intermediate support; With the slide assemblies move left and right, described hand member places the below of the fixedly end face baffle plate of right ends.
Described fixedly end face baffle plate and middle baffle plate are the assemblies of fixing expansion joint to be measured.
Described horizontal scale table is a graduation apparatus of measuring the expansion joint stroke.
Described vertical scale table is a graduation apparatus of measuring expansion joint off normal amount.
Described hand member is to regulate two fixedly members of end face baffle plate distance, is convenient for measuring the pipe joint of different size.
Described vertical oil hydraulic cylinder promotes the displacement that middle baffle plate produces vertical direction with the slide assemblies move left and right.
Compared with prior art, the utility model is measured the telescopicing performance of expansion joint through utilizing expansion joint self hydraulic action, has solved the telescopicing performance problem of only testing the housing voltage endurance capability in the past and can not test products; Up-down through vertical oil hydraulic cylinder effectively records the off normal amount of expansion joint under the band pressure condition; Rule through test machine itself can be directly perceived it is thus clear that the contraction elongation and the off normal amount of its expansion joint had solved in the past and will repeatedly measure the length of expansion joint own, reduced the test duration; Through the symmetrical balance principle, record two large deflection expansion joints simultaneously; The end face baffle plate that the two sides can move freely, the large deflection expansion joint of the different bore different sizes of convenient test; The performance that the large deflection expansion joint proving installation of the utility model is simple in structure, easy to operate, test data accurate, can comprehensively test expansion joint.
