Abstract
The utility model relates to an experimental bench for frictional factor between slide block and slideway, comprising a bench base, stands arranged on both end of the bench base, a transverse beam provided between the stands, which is characterized in that both ends of stands are respectively fixed with a hydraulic jack, and the hydraulic cylinders of the two hydraulic jacks have oppisite projecting direction. The top ends of the oil cylinders of the two hydraulic jacks are provided with pins which are connected with a channel steel. The upper side and lower side of the channel steel are respectively provided with sliders, and the lower slide is clamped by a cramping apparatus positioned on the bench base, and the upper slide is clamped by the cramping apparatus arranged on the oil cylinder top end of the loading hydraulic jack which is mounted on the lower side of the transverse beam. The utility model has the advantages that can acquire frictional factor under the condition of simulating a plurality of materials and loads and provide detailed technical parameter for actual configuration and pushing in construction.
Description
Technical field
The utility model relates to a kind of test-bed, particularly a kind of slide block and slideway friction coefficient test-bed.
Background technology
At present in some large-scale steel structure building operation, restriction because of execution conditions and hanging device, some new construction methods of installation have been adopted in the construction, wherein carry out the installation of large-scale steel structure with regard to the method that the whole displacement of accumulation assembly unit is arranged, whole steel construction moves at the pushing tow lower edge of hydraulic pushing equipment slideway, because the steel construction spatial extent is big, the thrust and the laying of thrustor in total of the reasonable disposition hydraulic top pushing device of one-piece construction in pushing tow are extremely important, and in order to reduce friction, be lined with the antifriction pad at the bottom of the column and between slideway, it is not enough by the technical parameter of consulting manufacturer only that but the material of antifriction pad is selected, safe and reliable in order to ensure what construct, need test to obtain the static and dynamic friction coefficient under the engineering actual conditions.
Summary of the invention
The purpose of this utility model is to solve existing problem in the prior art, provides a kind of.The utility model design slide block and slideway friction coefficient test-bed, comprise stand seat, the stand at stand seat two ends, the crossbeam between stand, it is characterized in that: in the stand at two ends, be fixed with hydraulic jack respectively, it is relative that the oil cylinder of two hydraulic jack stretches out direction, the oil cylinder top of two hydraulic jack has pivot pin to connect a channel-section steel, slide block is respectively arranged both sides up and down at channel-section steel, sliding block is by the anchor clamps clamping on the stand seat, and top shoe is by the anchor clamps clamping on the oil cylinder top of the loading hydraulic jack that is installed in the crossbeam downside.The utility model has the advantages that and to simulate under the situation of various materials and load, obtain its friction factor, for actual disposition and pushing tow in the construction provide detailed technical parameter.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise the stand 2 at stand seat 1, stand seat two ends, the crossbeam 3 between stand among the figure, it is characterized in that: in the stand 2 at two ends, be fixed with hydraulic jack 4 respectively, it is relative that the oil cylinder 5 of two hydraulic jack 4 stretches out direction, oil cylinder 5 tops of two hydraulic jack 4 have pivot pin 6 to connect a channel-section steel 7, both sides slide block 8 is respectively arranged at channel-section steel about in the of 7, sliding block 8 is by 9 clampings of the anchor clamps on the stand seat 1, and top shoe 8 is by anchor clamps 12 clampings on oil cylinder 11 tops of the loading hydraulic jack 10 that is installed in crossbeam 3 downsides.During use selected gliding material is made top shoe 8, sliding block 8, then according to the load condition in the concrete construction, the loading hydraulic jack 10 of starting 13 pairs of crossbeam 3 downsides of pumping source is loaded into loading force, starting pumping source 13 then loads hydraulic jack fixing in the stand 24 respectively, one loads pushing tow, another unloading, the one push-and-pull channel-section steel 7 of having a try, according to each hydraulic jack 4, load oil pressure gauge 14 readings of the loading of hydraulic jack 10, be converted into friction force and loading force, obtain the friction factor of concrete storeroom, also can in process of the test, drip the friction factor after lubricant obtains antifriction.
