Description
Technical field
The utility model relates to the instrument that a kind of flow of cement mortar measures, especially a kind of flow of cement mortar determinator.
Background technology
Flow of cement mortar is the plastic reflection of cement mortar.Instrument for testing fluidity of colloidal cement sand (abbreviation jumping table), flow of cement mortar jumping table method measures, and after mortar fluidity is carried out in accordance with regulations with glue sand test of beating on jumping table, the millimeter of bottom diffusion diameter represents.Diffusion diameter is larger, represents that fluidity of cement mortar is better.Glue sand reach the water yield needed for regulation fluidity larger time, then think that this cement water requiremen is larger; Otherwise water requiremen is less.
Instrument for testing fluidity of colloidal cement sand (abbreviation jumping table), jumping table has manual pulley and Electric Motor Wheel (automatically controlling jumping table to rotate) two kinds.Jumping table is primarily of casting iron framework, part of beating and power section composition, and part of beating, primarily of disk desktop and push rod composition, is uniformly distributed centered by push rod.The axis of machine frame hole is vertical with disk upper surface.When disk falls to contacting with frame, surface of contact keeps smooth, and becomes parastate in disk upper surface, contacts completely within the scope of 360 ° simultaneously.Power section comprises rotating shaft and cam.Cam is formed from steel, and its outer surface profile meets constant speed helix, and skin hardness is not less than Rockwell 55HRC.Should not discover to have when push rod and cam contact and beat, keep disk desktop steady in uphill process, do not shake.Rotating shaft can be driven by handwheel, can also be, rotation axis and rotating speed are the synchronous motor of 60r/min, and its rotating mechanism can ensure that mortar fluidity analyzer completes 25 times and beats in (25 ± 1) s.
The mensuration of flow of cement mortar is except using instrument for testing fluidity of colloidal cement sand, also can use glue sand agitator, die trial, tamper, slide calliper rule, the instruments such as pocket knife, glue sand agitator is first adopted to obtain the glue sand conformed with the regulations, die trial is made with metal material, be made up of truncated cone circle mould and die sleeve, with the use of, the cement mortar mixed is divided in two-layer rapid loading mould, use tamper and pocket knife simultaneously, carry out according to the pressure order of smashing of relevant regulations, smash pressure complete, take off die sleeve, pocket knife is tilted, erase with the angle of nearly level the glue sand exceeding truncated cone circle mould at twice from centre to edge, truncated cone circle mould is mentioned to remove vertically upward gently and namely obtains sample.Start jumping table, complete one-period and beat for 25 times.Beat complete, with the mutually perpendicular both direction expansion in the kind of calliper glue sand bottom surface of 300mm range diameter, calculating mean value, round numbers, uses mm unit representation.This mean value is flow of cement mortar.
Terminate to diameter measurement from glue sand adds water, test should complete in 6min, and existing jumping table does not possess measurement function, need manually to adopt kind of calliper, due to the urgency of time, often cause the error of measurement, and once time-out, the sample obtained just does not possess measures value, can only re-start test.
Summary of the invention
In order to overcome the deficiency of not high, the not reproducible measurement of existing instrument for testing fluidity of colloidal cement sand measuring accuracy, the utility model provides a kind of flow of cement mortar determinator, test findings shooting can be retained by this determinator, thus can accurately repeatedly measure at any time, not by the restriction of time, be convenient to obtain more accurate test figure.
The technical scheme that the utility model solves the employing of its technical matters is: comprise frame, to beat mechanism and actuating unit, described frame comprises sleeve and base, be connected by reinforcement between sleeve with base, described mechanism of beating comprises disk desktop and push rod, push rod is connected in the lower central position of disk desktop, push rod passes in the sleeve of frame, described actuating unit comprises cam and rotating shaft, the lower contacts of cam and push rod, cam is arranged in rotating shaft, rotating shaft is driven by motor or handwheel, also comprise the imaging device be installed on base, imaging device comprises CCD camera and tight shot, tight shot is installed on below CCD camera, tight shot is just to the center of disk desktop, CCD camera is also connected with CCD power supply, imaging device is fixed in gantry base by support, support comprises column and transverse arm, imaging device is fixed on the front end of transverse arm, the rear end of transverse arm is fixed on the top of column.
