The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Fig. 1 is the structural representation of the positioning device of travelling overhead crane that provides of the utility model specific embodiment.
A kind of positioning device of travelling overhead crane, comprise the steady arm body, described steady arm body comprises controller 1, detector and support 2, described controller 1 inside is provided with data handler, its surface is provided with instrument 3, instrument 3 can show the crane position at any time, described detector comprises angular-motion transducer 4 and position transduser 5, angular-motion transducer 4 and position transduser 5 all are positioned at the right side of swabbing pig 6, described support 2 is positioned at the right side of swabbing pig 6, and support 2 belows are provided with roller 7, and the guide rail of roller 7 belows is provided with some location sensitive bars 8, described swabbing pig 6 is positioned at beam 11 belows on crane 10 right sides, and described roller 7 contacts with guide rail 9.
Described position transduser 5 and location sensitive bar 8 non-contact inductives, the modes such as that noncontact induction can be adopted is infrared, magnetic strength or radar, and position transduser 8 is consolidated on the support 2, described location sensitive bar 8 has different parameters, equidistantly be arranged in successively guide rail 9 inside, described angular-motion transducer 4 is suitable with roller 7, and angular-motion transducer 4 is consolidated on the support.Because location sensitive bar 8 is of different sizes size, be of different sizes parameter, position transduser 5 is whenever sensed a certain location sensitive bar 8, the dimensional parameters of the corresponding unique location sensitive bar in this position will be input in the microprocessor and process, thereby calculate the distance of this position and reference position, as the static displacement of travelling overhead crane.
Be equipped with wire 12 between described data handler, angular-motion transducer 4, position transduser 5 and the instrument 3, wherein angular-motion transducer 4 links to each other with the signal input part of data handler with position transduser 5, instrument 3 links to each other with the signal output part of data sensor, data handler inside is provided with microprocessor and conv, and conv and detector are conducted.Wherein angular-motion transducer 4 is used for monitoring roller 4 self revolution, converting it into the dynamic displacement signal is input in the microprocessor, angular-motion transducer 4 also can be replaced by coder, position transduser 5 is by detecting different big or small location sensitive bars 8, judge travelling overhead crane 10 positions, position signal is input to as in the treater as the static displacement signal.
During concrete the use, an end of selecting location sensitive bar 8 guide rails 9 are housed is as the reference initial point, or is called initial position, and getting travelling overhead crane 10 is positive dirction away from the direction of reference origin, and crane 10 travels along positive dirction, and two kinds of situations are arranged this moment:
Situation one, position transduser 5 on the travelling overhead crane 10 is positioned on certain location sensitive bar 8, the position that this moment, position transduser 5 was sensed location sensitive bar 8, the dimensional parameters of location sensitive bar 8 changed into behind the electric signal calculate location sensitive bar 8 apart from the distance of initial position in the input microprocessor, with this distance as crane 10 static displacements, this moment, the dynamic displacement of crane was 0, and the value of static position is the value of crane position, and angular-motion transducer 4 resets.
Situation two, position transduser 5 on the travelling overhead crane 10 is between certain two location sensitive bar 8, the position of a location sensitive bar 8 after this moment, position transduser 5 was sensed, with the dimensional parameters of a rear location sensitive bar 8 change into calculate in the input microprocessor behind the electric signal after a location sensitive bar 8 apart from the distance of initial position, with this distance as the crane static displacement, simultaneously angular-motion transducer 4 continues record roller 10 self revolution, turn and calculate the at this very moment distance of position transduser 5 and a rear location sensitive bar 8 behind the rear one-tenth electric signal in the input microprocessor, with this distance as the crane dynamic displacement, two displacement sums have just been determined the distance of travelling overhead crane 10 with reference origin, the i.e. value of the position of the travelling overhead crane 10 of this moment.In addition, because the motion of position transduser 5 and roller 10 can be regarded the translation of same rigid body as, so the dynamic displacement of roller 10 is consistent with the dynamic displacement of position transduser 5.
If crane 10 travels along negative direction, this moment, dynamic displacement was negative value.The method of measurement that adopts the Static and dynamic displacement to combine, can effectively avoid can't precision locating of single-measurement static displacement, if can avoid again the measurement of whole process using dynamic displacement mode to cause larger accumulated error, so the mode of this compromise has improved the accuracy rate of steady arm greatly.
Below only with embodiment the utility model is illustrated, but the utility model is not limited to above-mentioned size and outward appearance illustration, more should not consist of any restriction of the present utility model.As long as any improvement or modification that the utility model is done all belong within the protection domain of claim opinion of the present invention.
