Description
Technical field
The utility model is related to a kind of test equipment of cement mortar, more particularly to a kind of mortar coagulation time tester.
Background technology
Mortar coagulation time tester is applied to determine wall surface mortar and the rate of set represented with penetration resistance and condensation
Time.
Authorization Notice No. discloses a kind of mortar coagulation time tester for CN203965434U utility model patent.Should
Utility model is pressed into test point in mortar by pulling handle downwards.But there is problems with the utility model：Due to this
Instrument is that test point is pressed into mortar by pulling handle manually, when the speed that hand pulls handle is uneven, can cause measurement
As a result it is inaccurate.
Utility model content
The purpose of this utility model is to provide a kind of measurement more accurately mortar coagulation time tester.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of mortar coagulation time
Analyzer, including base, the base are provided with pressure display unit, and the pressure display unit is provided with die trial, the base
Provided with column, the column is provided with support base, and the support base is provided with the pressure axis being threadedly coupled with support base, the pressure
Power axle upper end is provided with the handwheel being fixedly connected with pressure axis, and the lower end of the pressure axis is provided with test point.
, will be floating after mortar loading die trial by above-mentioned technical proposal, it is placed on pressure display unit, by pressure display unit
Reset, then drive the pressure axis on support base to rotate down by rotating handwheel, column plays support support base and pressure axis
Effect, pressure axis rotate down during drive test point push, pass through after test point, which is pushed, stretches into mortar certain distance
Pressure display unit obtains static pressure of the test point to mortar, and the static pressure force value divided by test point sectional area obtain Resistance Value, from starting to coagulate
Tie Resistance Value and reach that 0.5MPa time is mortar coagulation time.Because the rotational travel of handwheel is longer, it is easier to control
Uniform rotation, it is possible to so that the static pressure force value that pressure display unit is obtained is more accurate, to the measurement of mortar coagulation time also
It is more accurate.
It is further arranged to：The column has two and is located at the left and right sides of pressure display unit, the support base respectively
It is detachably connected respectively with two root posts.
By above-mentioned technical proposal, by two root posts come fixed supporting seat so that what the pressure axis on support base was rotated
When it is more stable, set support base and two root posts to be detachably connected and allow support base to move up and down regulation height on column
Degree so that the instrument is adapted to the container of a variety of different heights.
It is further arranged to：The column is provided with guide holder, and the guide holder, which is provided with, is used for the guiding through pressure axis
Hole, the guide holder is detachably connected with two root posts respectively.
By above-mentioned technical proposal, the guide holder being detachably connected is set on column, after the height regulation of support base,
Guide holder can also be followed to be adjusted up and down on column, guide holder leading as pressure axis during pressure axis is rotated down
To preventing pressure axis from rocking.
It is further arranged to：The support base side, guide holder side at every root post cooperation with being equipped with fixing bolt.
By above-mentioned technical proposal, in support base side, guide holder sideways with setting fastening bolt at every root post cooperation
So that support base and guide holder are fixed on column, the height of support base and guide holder can just be adjusted by unclamping fastening bolt.
It is further arranged to：The column upper end is equipped with latch segment.
By above-mentioned technical proposal, latch segment is set make it that support base and guide holder can only be on columns in column upper end
It is mobile, it will not depart from away from column.
It is further arranged to：The handwheel is provided with the handle being connected with hand wheel rotating.
By above-mentioned technical proposal, setting the handle being connected with hand wheel rotating to cause can during hand wheel rotating
To grasp handle always, it is not necessary to hand-off rotation, the situation of handwheel rotation speed change when being not in thus hand-off so that pressure
The speed that axle is pushed is more stable, and measurement result is also just more accurate.
It is further arranged to：The lower position block of position-limiting action from when being rotated down above the guide holder provided with pressure axis.
By above-mentioned technical proposal, the ultimate range that pressure axis is pressed downward is limited with lower position block, regulation guide holder
Highly so that the position of lower position block limitation is that test point is pressed into the position after certain distance in mortar so that operating personnel exist
It need not judge whether oneself has pushed enough distances according to graduation apparatus is stared at always when rotation, it is only necessary to always
Rotation can stop operating until lower position block props up guide holder.
It is further arranged to：The upper limit position block of position-limiting action from when being rotated up below the guide holder provided with pressure axis.
By above-mentioned technical proposal, due to test point press-in sand when directly regulation guide holder make it that lower position block plays position-limiting action
Slurry certain distance not only needs that directly test point is pressed into mortar, and also needs to the cooperation of graduated scale and could realize, in setting
Limited block so that the distance that pressure axis is moved between limited block up and down is just that test point needs to be pressed into the distance of mortar, so
Regulation support base is only needed to when regulation so that test point is just concordant with mortar liquid level, and then regulation guide holder causes the upper limit
Position block props up guide holder.
It is further arranged to：Multiple screwed holes, the lower limit are provided with the different height position of the pressure axis side
Block is provided with the caging bolt for coordinating fixed lower position block with screwed hole.
By above-mentioned technical proposal, upper limit position block is fixed on pressure axis with caging bolt, passes through multiple different heights
The cooperation of screwed hole and caging bolt cause pressure axis to have different displacements between upper limit position block and lower position block,
When distance of the mortar upper surface apart from container upper end face is determination value, can adjust pressure axis upper limit position block and lower position block it
Between displacement be test point pressure sand pitch from container upper end identity distance with a distance from, mortar upper surface from sum, so in regulation branch
When support seat height is spent, it is possible to adjust support base and be located just at container upper end face to test point, then cause the upper limit in regulation guide holder
Position block props up guide holder, avoids the need for adjusting support base again testing when completion needs to move away from container.
In summary, the beneficial effects of the utility model are：Handwheel is set to carry out rotation pressure axle increase stroke so that pressure
Axle to push speed more stable；The height of support base can be adjusted, and can adapt to the die trial of a variety of different heights；Upper limit is set
Block and lower position block so that need not go to stare at graduation apparatus during pressure axis is pushed.
