Description

Full-automatic petroleum asphalt penetration measuring instrument
Technical field
The present invention relates to a kind of full-automatic petroleum asphalt penetration measuring instrument, specifically be applied to fields such as building, traffic, especially high-grade highway is higher to the quality requirements of petroleum bitumen, with the on-site measurement instrument as construction enterprises, also can be applicable to the calibrating of supervision department.
Background technology
At present, the existing penetrometer of petroleum asphalt in market mainly is to adopt digimatic micrometer to carry out the reading and the measurement of pen., and the lifting of digimatic micrometer is that the pinion and rack that adopts is finished.Owing to be that the digimatic micrometer that adopts carries out the reading and the measurement of pen., thereby its measurement result has bigger 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 to be duplicate measurements three times under 25 ℃ situation in temperature, at every turn the canonical measure pin that all must more renew.Owing to be to adopt the artificial swing pinion of operator to drive the lifting that digimatic micrometer is finished in the tooth bar lifting, thereby realize changing the operation of canonical measure pin.Like this because handling time is at interval longer, thereby influence the accuracy of measurement result, operate also more loaded down with trivial details simultaneously.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of easy to operate, change the shortening of pin time, 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 by the measuring head web joint with measuring head lifting mechanism.
The outer cover of described whole instrument adopts the column outer cover to be fixed on the U type column by pad, fixation measuring head outer cover on the punch block case, the base outer cover is fixed on the flat base, on flat base and panel lead-in fixing before guidance panel, 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 type column, the upper end of U type column is by bolted top bearing cover plate, lower bearing end casing one end is fastened on the U type column, the other end is supported on the flat base by the end casing support column, ball-screw is contained on the U type 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 columns, and the measuring head web joint is connected on leading screw flange and the guide rail slide block by bolted.
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 last copper sheathing in the punch block case and following copper sheathing as guiding, slide bar is contained in the hole of punch block case, compression 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 by on the slide bar that is threaded in 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, measuring head lifting mechanism adopts, and to be stepper motor drive the ball-screw of little helical pitch by shaft joint, driven the rising and the decline of measuring head by the measuring head web joint by ball-screw.Because the adjustable-speed of stepper motor, therefore measuring changing in the pin process after finishing each time, 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, the speed of stepper motor is reduced, thereby make the measuring head fine motion, convenient pin is operated.Change the shortening of pin time, and can improve the measurement data accuracy.In this product, owing to adopted and in surveying instrument, be extensive use of the value that displacement transducer comes the surveyingpin in-degree, the shortcoming of in measuring process, just having avoided digimatic micrometer to measure like this, simultaneously because the output signal of displacement transducer can adopt computing machine to handle 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.
