Background technology
At present, the existing penetrometer of petroleum asphalt in market mainly is to adopt digimatic micrometer to carry out reading and the measurement of pen., and the lifting of digimatic micrometer is that the pinion and rack that adopts is finished.Owing to being that the digimatic micrometer that adopts carries out reading and the measurement of pen., thereby its measurement result has larger artifical influence factor, and its measurement data is not easy to follow-up preservation and processing simultaneously; The lifting of digimatic micrometer is that the pinion and rack that adopts is finished, and the measurement of national Specification petroleum asphalt penetration must be in the situation that temperature is 25 ℃ of duplicate measurementss three times, all must change the new standard surveyingpin at every turn.Owing to being to adopt the artificial swing pinion of operator to drive the lifting that gear rack elevating is finished digimatic micrometer, thereby realizing the operation of standard of replacement surveyingpin.Like this because the handling time interval is longer, thereby affect the accuracy of measurement result, operate simultaneously also more loaded down with trivial details.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby provide a kind of easy to operate, change the pin time shorten, can improve the full-automatic petroleum asphalt penetration measuring instrument of measurement data accuracy.
According to technical scheme provided by the invention, full-automatic petroleum asphalt penetration measuring instrument comprises outer cover three parts of measuring head, elevating mechanism, whole instrument.The measuring head device is connected the measuring head web joint and connects with measuring head lifting mechanism.
The outer cover of described whole instrument adopts the column outer cover to be fixed on the U-shaped column by pad, fixation measuring head outer cover on the punch block case, base outer cover is fixed on the flat base, guidance panel before flat base and panel lead-in are fixing, upper table surface by bolted on the lower bearing end casing.
Described measuring head lifting mechanism adopts line slideway to be fixed on the U-shaped column, the upper end of U-shaped column is by bolted top bearing cover plate, lower bearing end casing one end is fastened on the U-shaped column, the other end is supported on the flat base by the end casing support column, ball-screw is contained on the U-shaped column, stepper motor links to each other with ball-screw by shaft joint, stepper motor is fixed on the motor fixing plate, motor fixing plate vertically is fastened on the lower bearing end casing by four motor support posts, and the measuring head web joint is bolted connection on leading screw flange and guide rail slide block.
Described measuring head device adopts in the displacement transducer sensor installation device seat, sensor device seat is installed in the top of punch block case, the slip of displacement transducer is by being assemblied in upper copper sheathing in the punch block case and lower copper sheathing as guiding, slide bar is contained in the hole of punch block case, Compress Spring is contained in the centre of slide bar and punch block case, and the other end of slide bar is equipped with locating piece, electromagnet by bolted in the punch block case, suit counterweight counterweight on the needle holder, both are threaded connection on the slide bar of displacement transducer.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Measuring head lifting mechanism: in this product, what measuring head lifting mechanism adopted is stepper motor drives little helical pitch by shaft joint ball-screw, is driven rising and the decline of measuring head by the measuring head web joint by ball-screw.Because the speed of stepper motor is adjustable, therefore measuring each time changing in the pin process after finishing, can adopt higher speed that measuring head is risen fast and descend; And, can switch by guidance panel during near the pitch liquid level at surveyingpin, make the Speed Reduction of stepper motor, thereby make the measuring head fine motion, convenient pin is operated.Change the pin time shorten, and can improve the measurement data accuracy.In this product, owing to having adopted and in surveying instrument, being widely used the value that displacement transducer comes the surveyingpin in-degree, the shortcoming of in measuring process, just having avoided like this digimatic micrometer to measure, simultaneously because the output signal of displacement transducer can adopt computing machine to process and manage, thereby made things convenient for the follow-up management (as: filing and inquiry) of measurement data, the mistake of having avoided manual record and input to produce.
