Abstract
The utility model relates to a digital remote control standard dynamometer with more than 1 MN hauling power. The utility model adopts a tricyclic integrated design, namely, an upper pulling ring (1), a measuring component (4) and a lower pulling ring (5) are arranged on one structure to make the dynamometer be better in rigidity and strong in overload capacity. The measuring method adopts a lever amplification mechanism (3), a straining value is transmitted to a digital displacement sensor (2) and then to a long-distance digital dynamometer, the measuring result not only displays the displacement value (mm), but also directly reflects the force value (KN), and after being connected with a computer, the utility model can realize the functions of data processing, telemetering telecontrol and result automatic printing. The utility model can be operated not only as a standard dynamometer to measure the tension testing machine, but also as a working dynamometer to measure the force value of a hauling machine, a tractor and a towboat, and can be converted to be an electronic hanging balance.
Description
Technical field
The utility model relates to field of measuring techniques.Be worth tension tester energetically more than being mainly used in calibrating 1MN,, can be used to detect the tractive force of power machines such as being worth hauling engine, tractor, tugboat energetically again, also can be used for weighing apparatus---electronic crane scale as the power value of the horizontal anchor chain lacerating machine of calibrating 2MN.
Background technology
Being worth standard dynamometer more than the known 1MN energetically generally all is pressure type, when examining and determine the power that the pulls to value of tension tester with it, must use a kind of reverser just can carry out, and it is just very inconvenient that especially calibrating is worth horizontal testing machine energetically.The 0.3 grade standard dynamometer that uses at present generally all adopts pointer dial gauge to measure in addition, and the indicating value of gained is length value (mm), just can obtain power value (KN) through converting.And reading closely, very inconvenient during calibrating, and certain danger is arranged, even cause accidental bodily injury's accident.
Summary of the invention
In order to solve the known deficiency that is worth percentage tabular form standard dynamometer energetically, the utility model provides a kind of large traction digital remote control standard dynamometer, not only rigidity is big, overload capacity is strong for it, measuring accuracy is high, easy to use, and the testing result numeral shows, and can be connected the remote control that takes remote measurement with computing machine, and can be used for examining and determine tension tester as standard dynamometer, can be used as the tractive force that the work dynamometer detects various hauling engines again.
Technical scheme
The technical scheme that its technical matters that solves the utility model adopts is: by last draw ring (1), digital displacement level sensor (2), lever measurement by magnification mechanism (3), load-sensing unit (4), following draw ring (5) and digital dynamometer are formed, load-sensing unit (4) produces strain under the action of pulling stress of last draw ring (1) and following draw ring (5), strain value is transferred to high-resolution digital displacement transducer (2) after amplifying 5～7 times by the known lever measurement by magnification mechanism (3) that is installed on the load-sensing unit (4), testing result is shown by numeral, to go up draw ring, it is integrated that load-sensing unit and following draw ring are designed to three rings, and this can improve the rigidity and the overload capacity of dynamometer.On measuring method, adopt digital displacement sensor to replace pointer dial gauge, improve the accuracy of measuring.Digital displacement sensor is established output socket in addition, is connected with the remote digital dynamometer by cable, solves the inconvenient or impossible problem of on-the-spot reading.Testing result directly shows the power value, and not only convenient but also safety in order to take remote measurement or the remote-controled digital dynamometer, can be connected functions such as carrying out data processing, program setting, the automatic printing of result with computing machine.
Beneficial effect
1, Zheng Ti rigidity is big, and overload capacity is strong, and is easy to loading and unloading during measurement.
2, both can show shift value (mm), can directly show power value (KN) again.
3, during on-the-spot the detection, be connected with digital dynamometer by cable and can carry out telemeasurement, convenient reading is guaranteed personal safety again.
4, with behind the computer link can carry out data processing, remote measuring and controlling, test findings and print automatically, and also have functions such as peak value maintenance, kinetic measurement.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified
Accompanying drawing is a theory structure synoptic diagram of the present utility model
1, goes up draw ring 2, digital displacement sensor 3, lever measurement by magnification mechanism
4, load-sensing unit 5, following draw ring
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, last draw ring (1) is designed to annulus, load-sensing unit (4) and is designed to oblate ring and following draw ring (5) to be designed to three rings of annulus coaxial and at one on the whole.Another embodiment is: load-sensing unit (4) produces strain under the action of pulling stress of last draw ring (1) and following draw ring (5), strain records by digital displacement sensor, and gives digital dynamometer and directly demonstration with digital transmission.In addition, the numeral dynamometer also can be connected with computing machine during for remote-control romote-sensing, and remote control by setup program takes remote measurement.
Claims (2)
1, the digital remote control standard dynamometer of a kind of large traction, form by last draw ring (1), digital displacement level sensor (2), lever measurement by magnification mechanism (3), load-sensing unit (4), following draw ring (5) and digital dynamometer, load-sensing unit (4) produces strain under the action of pulling stress of last draw ring (1) and following draw ring (5), strain records by digital displacement sensor, and give digital dynamometer with digital transmission and directly show, it is characterized in that: go up draw ring (1), load-sensing unit (4) and (5) three of following draw rings and encircle coaxial and on an one-piece construction.
2, the digital remote control standard dynamometer of large traction according to claim 1 is characterized in that: measure and adopt digital displacement sensor (2), connect to form with cable and digital dynamometer.
