Description
Technical field
The present invention relates to mortar strength investigating instrument calibrating installations.
Background technology
Mortar strength investigating instrument is the special instrument of Site Detection building masonry strength, is made in construction quality detection process
With very extensive.Mortar strength investigating instrument is as shown in Figure 1, include mainly shell 9, shell 9 is interior to be equipped with working spring 92, and work bullet
The upper end of spring 92 is supported by injection bar 91, and the outside of shell 9 is equipped with trigger 94, and trigger is equipped with block protrusion, is also cut with scissors on shell
It is connected to the hook 93 for injection bar 91 hook block, hook 93 includes the hook portion 931 positioned at hinge joint both sides
And bar part 930, the block protrusion of trigger can carry out bar part block realization and load to the locking of injection bar.
In use, cocking 94 rotates and releases block protrusion to hooking 93 block, and then compressed working spring 92 is discharged,
And the elastic force discharged by working spring 92 squeezes into the upper end of injection bar 91 in masonry upwards, to be examined according to driving depth
Survey the intensity of masonry.Mortar strength investigating instrument is often led because of the variation of working spring elasticity after used a period of time
Accuracy is caused, therefore, periodically mortar strength investigating instrument calibrate just particularly significant.
In this regard, the Chinese invention patent that Authorization Notice No. is CN204027952U, Authorization Notice No. is 2014.12.17 is just
A kind of mortar penetrometer calibrating installation is disclosed, this calibrating installation includes rack, the support base for placing penetrometer, is used for
That keeps out penetrometer injection bar keeps out force measuring machine and the thrust loading and unloading body for applying thrust load to penetrometer.Make
Penetrometer upside down is carried out block limit by the used time by the force measuring machine of keeping out of injection bar upper end on support base to injection bar
Position, then by the thrust loading and unloading body pushing tow shell of injection machine lower end and compression work spring, until hook and injection bar
It hooks, and completes to load by trigger block hook.When needing unloading, is pulled by mechanism makes trigger break off relations and discharged by trigger
Spring and injection bar is got.
But this calibrating installation that is, in loading procedure, is linked up with when by thrust loading and unloading body compression work spring
Counter-rotating under the action of linking up with compression spring, bar part tilt outward, need to avoid trigger from keeping off trigger pressure manually at this time
In the outside of hook, manual releasing trigger is needed again when hooking and injection bar will hook and makes trigger in the work of trigger compression spring
It firmly descends backwards rotation to be caught in hook inside to complete to load later to hang with injection pike pole in hook.At this time since injection meter falls
It sets on support base, is tended not to sometimes when trigger is affected by gravity the backwards rotation under the active force of trigger compression spring completely
It into inside is hooked, results in loading unsuccessfully in this way, human hand auxiliary is generally required in actual mechanical process and pulls trigger upwards.This
Sample not only needs manually to trigger depression in the whole process, it is also necessary to manually above be pushed away to trigger, operation difficulty is very big, calibrating
The success rate of experiment is relatively low.
Invention content
The purpose of the present invention is to provide a kind of mortar strength investigating instrument calibrating installations, to solve existing calibrating installation
It needs in use to manual depression and upper trigger, the big problem of operation difficulty.
In order to solve the above-mentioned technical problem, mortar strength investigating instrument calibrating installation of the invention adopts the following technical scheme that：
A kind of mortar strength investigating instrument calibrating installation, including rack, rack are equipped with for installing inverted mortar strength investigating instrument
Support base is additionally provided with the trigger adjustment mechanism for adjusting trigger in load, uninstall process, the trigger tune in the rack
Complete machine structure, which includes moving member and the controller of driving moving member action, the moving member, to be had for being pushed in loading procedure
Trigger makes it forward rotate, is linking up with the pressure contravention for making its backwards rotation with release trigger before injection bar hook, and the pressure is touched
End is equipped with the magnetic-adsorption portion for the adsorption capacity that trigger backwards rotation is supplied to after unclamping trigger.The mortar strength inspection of the present invention
Survey instrument calibrating installation by moving member can in loading procedure lower trigger squeeze, avoid trigger gear bar part outside and shadow
Hook is rung to be turned out；When hook will be hooked with injection bar, moving member can decontrol trigger again makes trigger in trigger spring
Backwards rotation under active force, while the magnetic-adsorption portion of moving member pressure contravention can be supplied to the adsorption capacity of trigger backwards rotation again,
The adsorption capacity overcomes influence of the trigger gravity to trigger backwards rotation, and the block protrusion of trigger can be made to turn to bar part
Inside, realization accurately load, improve the success rate of calibration test；Whole process does not need human hand auxiliary simultaneously, realizes
Calibration test automates, easy to operate.
Further, the moving member is the oscillating rod around horizontal rotation axis rolling assembling, and the pressure contravention is to swing
The free end of bar.Using oscillating rod as moving member, the driving mechanism structure of driving oscillating rod rotation is simple, and driving is convenient, pendulum
The rotational angle of lever is limited, occupies little space.
Further, the magnetic-adsorption portion is the magnet set on free end.One block of magnet need to only be fixed and be connected when use
It is connected on oscillating rod free end, it is simple in structure.
