Abstract
The utility model relates to a portable dynamometer, wherein, the weight of which is only some kg. A movable and portable dynamometer is a device which is assembled by adopting a proper mechanical structure mode connection, and the utility model is composed of device components of a gantry bracket, a spiral type jack, a standard area force application plate, a sensor, a display instrument, a direct-current power supply, a miniature printer, etc. The utility model can carry out intensity detection and standard force application for some article materials directly on a working site.
Description
The utility model relates to a kind of dynamometer that can carry out strength of materials detection at operation field.Be that weight has only several kg, can carry, use as instrument, can carry out the standard application of force the novel portable dynamometer.
At present, existing Material Testing Machine or the force measuring machine that the strength of materials is detected, volume is all very big, and weight of equipment is also very big, is to be difficult to move.Therefore, generally all can only be fixedly mounted in the experiment.So the existing work that the strength of materials is detected also often can only be to carry out in the laboratory.Concrete grammar is to extract small amount of sample, is sent to the laboratory, on fixed installation good Material Testing Machine or force measuring machine, carries out the intensity detection or the standard application of force.
The main defective of such method is that cumbersome sometimes, workload is big, be sent to the laboratory to sample from operation field; Verification and measurement ratio is little, has only small amount of sample detected as representative; To the article that have detect or the standard application of force very difficult, as concrete prefabricated floor, heavy caliber cement pipe or the like.
The purpose of this utility model is: provide a kind of novel dynamometer, carrying out the article material under the prerequisite of the intensity detection and the standard application of force equally, by alleviating the weight of dynamometer, reduced volume, can carry, make testing simple and convenient, not be only limited in the laboratory; Dynamometer is used as instrument, can detect, improve verification and measurement ratio at operation field, as in building industry to the every concrete prefabricated floor that will go up the roof, all can carry out intensity detection, to ensure safety; Solve the detection difficult that some article materials sometimes cause because of various factors or waste time and energy even also expensive situation; Improve detection means, precision and level by application electric technology.
The purpose of this utility model is achieved in that with spiral lifting jack as application of force source, as load-sensing unit, shows the power value with Displaying Meter with digital form with high-precision sensor.Use the mini-printer print data, adopt suitable physical construction mode to assemble, form a standard application of force and measurement mechanism.The article material is carried out the intensity detection and the standard application of force.Specific as follows:
With a high precision force cell, be fixed on the base plate of suitable intensity.When sensor is stressed, have one with stressed size be directly proportional and linear electric signal output.
On base plate, be fixed with a Displaying Meter simultaneously.When sensor was stressed, the signal of output was sent to instrument.Demonstrate the stress value of sensor with digital form by instrument.And the driving printer prints data.
A bearing plate is arranged above the sensor, fixedly connected with sensor.Testee can be placed on this above bearing plate.
It is to calculate the plate of determining according to request for utilization that an area size and shape are arranged, and claims standard area force application board to be placed on above the testee.It can realize the purpose that unit area is stressed.
Put a spiral lifting jack above the force application board again.Put a back up pad above the lifting jack.By a rigidity and the flexible gantry support that combines of forming by wire rope and steel crossbeam and base plate, be the upper support point of lifting jack.Hard and soft combination can make the gantry support respective activity.When needs used additive method to support lifting jack, this gantry support can fall down need not.
Like this, by the operation lifting jack, just can carry out the application of force to testee.Since sensor, testee, standard area force application board is connected up and down and is stacked, so the application of force of the suffered lifting jack of several persons, and size equates.Like this, the value of the jack pair testee institute application of force just can be come out by sensor measurement, is shown with digital form by instrument.By the proper handling lifting jack, testee is imposed corresponding power, by instrument indication value, observe the performance situation of testee under the effect of this power, just can realize the intensity detection and the standard application of force.
Because what adopt is spiral lifting jack, therefore the power that testee is executed is stable.
Because lifting jack is through standard area force application board, with the power transfer function to the testee, so suffered power of testee, it is stressed to be actually unit area.Calculate very convenient.
The portable force gauge working power is 5 volts of direct currents, is supplied with by 6 volts of batteries.
Owing to adopt such scheme, can make intensity detection to the article material, be not limited to carry out in the laboratory.Can carry out equally at operation field.And because of in light weight, volume is little, can carry, and uses as instrument, has made things convenient for testing.Also can solve some difficult problems that existing method is difficult for detection.
As: to brick commonly used in the building industry, sandstone sample piece, cement pouring sample piece early strengths etc. all can be placed on the force measuring machine and directly detect on the spot at operation field.
And for example: to concrete prefabricated intensity detection of hugging plate, need only the variation of doing slightly on the operation method, just can carry out.Be placed on the prefabricated board as long as standard area force application board changed, dynamometer integral body is placed on the standard area force application board, without the gantry support of dynamometer, but make a circle with wire rope, under be enclosed within below the prefabricated board, on be enclosed within above the lifting jack back up pad, form a big flexible gantry support.At this moment operate lifting jack,, just can carry out the application of force, carried out intensity detection prefabricated board by transmission to the application of force and the power of bearing plate.Area according to instrument indication value and standard area force application board just can record the intensity situation of prefabricated board.(expression value in accordance with rites is 100kg, and force application board standard area is 0.01 square metre, (0.1m*0.1m), at this moment is equivalent to the power that every square metre of prefabricated board is bearing 10t).
For another example: some body of cement or other structures at the scene, building ground of standing to having watered, with the concrete prefabricated method of hugging plate of similar detection recited above, also can carry out the intensity detection or the standard application of force easily.
