The novel experiment slide bearing enables stress situation to be close to an ideal mode, improves experiment accuracy, greatly improves reliability of experiment data and further enables people to well know mechanical property of experiment members and materials.
Description
Technical field
The present invention relates to the sliding bearing technical field, exactly is a kind of new test sliding bearing device, namely provides a kind of in test, and vertical bearing reaction only is provided, and test specimen can be connected in the supporting along level to activity.Compare with existing sliding bearing, the test error that the present invention has effectively reduced the space between test specimen and the supporting constraint and caused has improved the degree of accuracy of test findings greatly.The present invention is applicable to and need to only provides in the test of vertical supporting counterforce device.
Background technology
Along with China's expanding economy, the diversification of safety of building performance and building materials receives much concern.Need to understand the various mechanical properties of building element and building materials before design and construction, this need to obtain by a large amount of scientific experimentations.Therefore each member and new material need to do detection and the test of various security performances in the buildings before coming into operation.In process of the test, the supporting coupling arrangement testing equipment that is absolutely necessary.Many factors that affect test accuracy are arranged in process of the test, and the performance of fulcrum arrangement is one of wherein important influence factor.But existing sliding bearing has size unadjustable, and when the test component size is not mated with the supporting size, the shortcomings such as larger space will be arranged between the inboard roller bearing of test component and supporting upper surface.The test specimen of sliding bearing end can perk when test specimen is loaded.Actual loading situation and desirable stressing conditions gap are larger, have had a strong impact on test accuracy.
Said fulcrum arrangement refers to the weight in order to supporting container or equipment, and makes it be fixed in certain position, the vibration when bearing simultaneously test and the supporting member of various external loads.According to the difference of using function, the classification of supporting has fixed bearing and two kinds of supportings of sliding bearing.Fixed bearing refers to can the confining part support end produce translation, the rotation that simultaneously again can confining part produces.Sliding bearing and fixed supported difference are to make member produce translation.Existing sliding bearing device have supported weight, restriction (or guiding) displacement, control (rolling) the moving characteristics of shaking also have outward simple in structure, bearing capacity greatly, strong adaptability, long service life, the advantage such as cheap.But the most size of existing sliding bearing is unadjustable, when test component size and fulcrum arrangement size are not mated, because have larger space between the inboard roller bearing of test component and supporting upper surface, sliding bearing can not in time give test specimen enough vertical constraining forces when test specimen is loaded.So just impel real stress model and theoretical model not to be inconsistent, therefore can cause larger error to test findings.
Summary of the invention
The purpose of this invention is to provide a kind of new test sliding bearing device.
The present invention has carried out further improvement to existing sliding bearing, thereby increases substantially test accuracy.
The present invention is installing two slideways with the fixing lower side panel of base plate, and every certain distance the bolt mouth is set in the slideway outside.The position that can regulate like this left and right sides plate makes it be fixed on the required size position.Epipleural is collapsible plate, and the folding position adopts the mode as door-hinge to be turned up to the centre by two ends, the left and right sides as axle take the outward flange of plate, and the width of every section folded sheet and above-mentioned bolt mouth adapt.And card article is installed in its both sides, at the correspondence position of the left and right sides plate slideway is set.Roller bearing is all installed in the inboard of the upper and lower, left and right plate of sliding bearing, and the roller bearing of upper and lower plates is take the plate center as axle, and length is 300mm, and the roller bearing of left and right sides plate is roller bearing moving up and down.Can effectively reduce space between test specimen and the epipleural roller bearing by this design, make the inboard roller bearing close contact of test specimen and epipleural, thereby improved test accuracy, greatly increase the reliability of test figure.The main members such as collapsible epipleural, slideway, bolt that use, the size of sliding bearing can be changed with necessary requirement, space when effectively having reduced test between test specimen and supporting, make the stressing conditions of test specimen more near ideal model, improve the precision of test figure, thereby make people understand more truly the stress performance of test test specimen.
Advantage of the present invention and beneficial effect
By the slip of epipleural and left and right side plate, can obviously reduce test specimen and do the time spent at bearing load, the space between the inboard roller bearing of epipleural and the test specimen.Thereby guarantee the reliability of test figure, improve test accuracy.Fulcrum arrangement plays vital effect in process of the test, make people further understand more really the various mechanical properties of test specimen by this improvement, the science data that provide the foundation for the application under construction of this test specimen.

Embodiment
The present invention is described in detail below in conjunction with technical scheme with reference to accompanying drawing.
The sliding bearing device pattern that the present invention proposes is shown in Fig. 2-8.
Sliding bearing among the present invention mainly is comprised of roller bearing on base plate, four side plates and the plate.The lower side panel of sliding bearing device and the connected mode of base plate are welding, slideway is installed in appropriate location at lower side panel, left side plate can slide along slideway, make fulcrum arrangement can be applicable to the demand of the sample dimensions in the variable range with this, when the size of the size of fulcrum arrangement and test specimen is more or less the same, with the bolt on the plate plate is fixed on this position.Epipleural adopts the folded sheet of being turned up to the centre by two ends as axle take the outward flange of plate, and the width of every section folded sheet is half of left side plate sliding distance.Relevant position at left side plate arranges slideway, and at the inward flange of every section folded sheet card article is set, in order to the fixed upper plate.Meanwhile, the roller bearing on the biside plate is made centered by the plate center up and down, and length is 300mm, and the roller bearing of the left and right sides is made the pattern that can slide up and down.
