Abstract
The utility model discloses a stroke correction unit of a numerical control elevator, which comprises a pulse encoder, a programmable controller, a displayer and two sets of upper portion in-place switches. The stroke correction unit of the numerical control elevator is characterized in that synchronous switches are arranged at a certain distance from the upper portion in-place switches, and each synchronous switch corresponds to a position height. Each time a container triggers one synchronous switch in the container lifting process by the elevator, a position correction signal is sent to the programmable controller for once, and the programmable controller converts the height of the position where the synchronous switch is located into corresponding data information to write in a counter. The stroke correction unit of the numerical control elevator can control the elevator to enable the speed of the elevator to be reduced to a low level when the elevator moves to in-place points where the in-place switches are located, namely the stroke correction unit of the numerical control elevator controls the elevator to move slowly when the elevator is in place, and impact does not occur substantially when the in-place switches move.
Description
Technical field

Background technology
The stroke detection of numerical control gig is the stroke value that the pulse count through pulse coder calculates; What calculate is relative value; Most gigs pass through to bit switch and realize putting in place parking; Because the numerical control gig adopts stroke one velocity setting more, speed is not also reduced to lower speed during parking, when putting sudden stop in place, can cause huge physical shock in the big inertia system like this.Therefore, press for the stroke alignment technique of a kind of numerical control gig of exploitation.
The utility model content
The task of the utility model is to provide a kind of stroke correcting unit of numerical control gig, can prevent the situation that stroke calculates and skip bucket (or cage) actual position is not inconsistent that gig is caused because of the changeability factor affecting in operational process.
Its technical solution is:
A kind of stroke correcting unit of numerical control gig comprises pulse coder, Programmable Logic Controller, the telltale that is used for detecting the gig stroke, the two cover top location switches that are positioned at pit shaft; The known height and position of location switch is provided with at least one synchro switch above each; Every corresponding absolute location height of synchro switch; In the process of gig lifting container when container triggers a synchro switch; Just send position correction signal one time to Programmable Logic Controller; Programmable Logic Controller just becomes the absolute location height conversion at this synchro switch place corresponding data information to write counting machine, simultaneously according to this data message correction stroke value, and transfers to telltale to the stroke value after proofreading and correct and shows.
Above-mentioned synchro switch is divided into two groups, and each group has more than two or two, and the synchro switch on the same group is arranged in order from top to bottom.
Above-mentioned synchro switch is a magnetic switch.
Above-mentioned Programmable Logic Controller is provided with the synchro switch inspection module that before carrying out correction tasks, can detect the operating state of each synchro switch.
Above-mentioned Programmable Logic Controller is provided with to follow the tracks of the variation in thickness of gig master rotor friction lining and detects and the design factor correction module of proofreading and correct.
The utlity model has following useful technique effect:
The utility model is provided with two synchro switches at least in pit shaft; Absolute location height of each correspondence of synchro switch (demarcation); In gig lifting container lifting process, when container is elevated to the height of a certain synchro switch, just can trigger this synchro switch, sending position correction signal to controller when;, and transfer to telltale to the stroke value after proofreading and correct and show according to the absolute location height at this synchro switch place correction stroke value by force by controller.Because the travel values between the top location switch of each synchro switch and its homonymy is very accurately; Proofread and correct through above-mentioned stroke; Gig can run to location switch in this distance and belong to site speed per hour degree and can reduce to lower level; Control is gone slowly it when just putting in place, when each location switch action, does not impact basically.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
Fig. 1 is the structural principle schematic block diagram of a kind of embodiment of the utility model.
Fig. 2 is the principle of work and power schematic block diagram of the Programmable Logic Controller in Fig. 1 mode.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of stroke correcting unit of numerical control gig comprises pulse coder 2, Programmable Logic Controller 3, the telltale 4 that is used for detecting gig 1 stroke, a cover top location switch 5 and another set of top location switch 6 that is positioned at pit shaft.Location switch 5 known height and positions are provided with two left side synchro switches 7 above the distance; Location switch 6 known height and positions are provided with two right side synchro switches 8 above the distance; Two left side synchro switches 7 form one group of synchro switch; Two right side synchro switches 8 form another group synchro switches, and two synchro switches on the same group are arranged in order from top to bottom, and each synchro switch can be selected magnetic switch for use.Every corresponding absolute location height of synchro switch; In the process of gig 1 lifting container when container 101 triggers a synchro switch; Just send position correction signal one time to Programmable Logic Controller; Programmable Logic Controller just becomes the absolute location height conversion at this synchro switch place corresponding data information to write counting machine, simultaneously according to this data message correction stroke value, and transfers to telltale to the stroke value after proofreading and correct and shows.
The quantity of the synchro switch in above-mentioned a group can also elect one as, more than three or three.
Above-mentioned Programmable Logic Controller is provided with the synchro switch inspection module that before carrying out correction tasks, can detect the operating state of each synchro switch.The utility model is in actual moving process; Utilizing synchro switch inspection module that the state of each synchro switch is checked, is a kind of preventive measure of gig stroke calibration function, realizes mainly whether the action of inspection synchro switch in the downward process of moving of skip bucket (or cage) is normal; Otherwise; Just give a warning, cancel the stroke calibration function of this switch simultaneously automatically, and limiting operation.If double to detect the action of same synchro switch not normal, gig coupler lock automatically with the hand hoisting mode, the caution hoister should be transformed into checks that mode of operation overhauls.
Above-mentioned Programmable Logic Controller is provided with to follow the tracks of the variation in thickness of gig master rotor friction lining and detects and the design factor correction module of proofreading and correct.The zero offset capability of design factor correction module is mainly realized the tracking of gig master rotor friction lining variation in thickness is detected, and the stroke of accomplishing single impulse calculates.Gig work is at automated manner; And under the condition of smooth operation more than 10 minutes; The stroke value that detects a certain fixed position surpasses certain calculation error scope of (or being lower than) this position traveled distance value; Just automatically start the design factor calibration function, reduce the stroke calculation error that the inaccuracy because of design factor causes to greatest extent.
