Drilled pile specific gravity of mud measuring device and measuring method
Technical field:
The present invention relates to a kind of drilled pile specific gravity of mud measuring device and measuring methods.
Background technology:
Drilled pile specific gravity of mud measuring method is using specific gravity of mud meter at present, this is a kind of lever balance dress
It puts, measures specific gravity of mud according to balance between two forces principle, application method is that the mud that will be measured fills mud cap, and capping is simultaneously
The mud overflowed from aperture to be cleaned, is subsequently placed on stent, mobile rider makes lever be horizontal, i.e., bubble is in center,
Read the relative density of scale, as mud shown in the left survey of rider.
There are following problems for this drilled pile specific gravity of mud measuring method:Operate comparatively laborious, the density of water
It is not one in different temperatures and determines value, different people differs the equalization point perception of this device, and this method has certain miss
Difference, while manpower is needed to remove the mud of wiping volumetric flask spilling in measurement process, wiping process is time-consuming, and wiping is not thorough, meeting
Experimental result is had an impact.
Invention content:
The purpose of the present invention is overcoming current measuring method there are error, the problem of density of water can be affected by temperature, carry
Relative density is measured using quality of mud fluid for a kind of, measurement result is accurate, the drilled pile mud phase used convenient for field condition
To density measuring equipment and measuring method.
Above-mentioned purpose is realized by following technical scheme:
Drilled pile specific gravity of mud measuring device, composition include:Dynamic equipment and driver, the upper master on the dynamic equipment
Gear is meshed with the upper pinion on the driver, and the threaded rod screw thread of the driver lower part and scourer connects
It connects;The dynamic equipment includes worm screw, and the pedestal on the worm screw and stent is connected by bearing, the front end of the worm screw
Fixing nut is fixed with, the worm screw is meshed respectively with lower main transmission worm gear, lower auxiliary driving worm gear, the lower auxiliary driving
Worm gear and the upper master gear are respectively fitted in fixed link, and the upper and lower ends of the fixed link are led to respectively with the stent
Cross bearing connection.
The drilled pile specific gravity of mud measuring device, the scourer include fixing with the threaded rod and connect
The bottom plate connect, the bottom plate left and right sides are respectively arranged with two hairbrush, and the hairbrush top is passed through on the bottom plate
Bar hole, the bottom plate connect with the hairbrush by clamp nut.
The drilled pile specific gravity of mud measuring device, the lower main transmission worm gear top is fixed with circular groove plate to be connected
It connects, magnetite is fixed in the circular groove plate, the lower main transmission worm gear lower part is rotated with the stent by strut to be connected
It connects.
Advantageous effect:
1. the structure of the invention by the way that dynamic equipment, driver and scourer is set to be combined so that it does not need to manpower and is wiped,
Comprehensive wiping can be carried out at the same time to both sides above and below volumetric flask outer wall by the rotation of hairbrush, wiping process is time saving, wiped clean,
Prevent remaining mud from being impacted to experimental result.
The present invention using the quality of mud and stirring mud both water come the relative density of computation of mud, not by water
Temperature interference, measurement result is accurate, easy to operate, convenient for field carry out experimental implementation.
The present invention weighs quality to measure the relative density of mud by balance, it is therefore prevented that thinks to observe and operates what is generated
Error improves the accuracy of measurement result.
Volumetric flask bottom of the present invention is irony, passes through the actuation between the magnetite in volumetric flask and circular groove plate, it is ensured that
The stabilization of volumetric flask prevents from having an impact the quality in volumetric flask.
