Abstract
The utility model discloses an intelligent elevator rope slacking protection device which comprises an outer shell, an upper rope hoisting sheave shaft encoder and a lower rope hoisting sheave shaft encoder, wherein a programmable logic controller (PLC) arranged inside the outer shell is connected with a touch screen, a sound device and a normally closed joint through transmission wires. The upper rope hoisting sheave shaft encoder and the lower rope hoisting sheave shaft encoder are respectively connected with the PLC through transmission cables, and the normally closed joint is connected with a safety circuit of an elevator in series. The PLC is utilized for the intelligent elevator rope slacking protection device, signals of operation speed of two sheave shafts having the same diameter are collected and converted, wherein two lifting steel wire ropes which are an upper rope and a lower rope of the double coiling block winding type elevator respectively pass through the two sheave shafts, and then the signals are calculated, identified and judged to achieve protection for mine elevator rope slacking.
Description
Technical field the utility model belongs to gig rope creep protection device technique field, relates to a kind of intelligent gig rope creep protection device.
Background technology prior art gig is when transferring lifting container, and when phenomenons such as (as: falling protector are embraced reasons such as card, cage guide distortion and caused) took place if lifting container is stuck in pit shaft, if gig remains in operation, hoisting cable will relax.Like the untimely safety return circuit that sends signal and cut off gig,,, cause weighing down the generation of container accident then easy generation container falls with free-fall velocity and breaks hoisting cable just in case the container behind the slack rope is movable again.In addition, by the serious container of jam, the rope of Panasonic can be looped in pit shaft, as being tangled by the container of another rising, also major accident possibly take place.Therefore; The effect of rope creep protection device can in time be sent signal and break off the mine hoist safety loop when above-mentioned phenomenon takes place exactly safety brake is had an effect, and eliminates accident potential, and the accident that prevents enlarges; But, present rope creep protection device of finding to have this effect as yet.
The 427 regulation of colliery rules: the drum winding winch must be provided with rope creep protection device and access security loop and alarm loop, when steel rope is lax, can cut off the power supply automatically and report to the police.But the rope creep protection device that uses at present be mechanical lever-type mostly, owing to hoisting cable in operational process, vibration amplitude is big, sensitivity is low, is prone to misoperation, simultaneously, because often touch, can make the damage of rope creep protection device and loses efficacy.
The purpose of summary of the invention the utility model is to solve the deficiency that prior art exists; A kind of PLC of utilization programmable logic controller (PLC) is provided; The acquisition of signal conversion back of the sky wheel shaft operating speed through two hoisting cables of two reel cylindrical drum hoists promptly being gone up two same diameter that rope and play rope pass through respectively, through calculating, identification, judge, thereby the device of realization mining intelligent gig rope creep protection.
To achieve these goals; A kind of intelligent gig rope creep protection device of the utility model; It comprises shell, on restrict head sheave shaft encoder and following rope head sheave shaft encoder; Be provided with the PLC programmable logic controller (PLC) in the said shell, the PLC programmable logic controller (PLC) is connected with normally closed contact with touch-screen, sound device through transmission line; The said rope head sheave shaft encoder of going up is connected in the PLC programmable logic controller (PLC) through transmission cable respectively with the head sheave shaft encoder of restricting down; Said normally closed contact seals in the mine hoist safety loop.
The utility model utilizes the PLC programmable logic controller (PLC); The acquisition of signal conversion back of the sky wheel shaft operating speed through two hoisting cables of two reel cylindrical drum hoists promptly being gone up two same diameter that rope and play rope pass through respectively, through calculating, identification, judge, thereby the protection of realization mining elevator slack rope.
Appended drawings 1 is the utility model structural principle scheme drawing.
Among the figure 1, go up hoisting cable head sheave shaft encoder 2, hoisting cable head sheave shaft encoder 3, PLC programmable logic controller (PLC) 4, touch-screen 5, sound device 6, normally closed contact 7, shell down
The specific embodiment is according to accompanying drawing; The utility model it comprise shell 7, on restrict head sheave shaft encoder 1 and following rope head sheave shaft encoder 2; Be provided with PLC programmable logic controller (PLC) 3 in the said shell 7, PLC programmable logic controller (PLC) 3 is connected with touch-screen 4, sound device 5 and normally closed contact 6 through transmission line; The said rope head sheave shaft encoder 1 of going up is connected in PLC programmable logic controller (PLC) 3 through transmission cable respectively with the head sheave shaft encoder 2 of restricting down; Said normally closed contact 6 seals in the mine hoist safety loop.
The installation of the utility model major part and principle of work: on the head sheave shaft encoder 1 of restricting be installed in the last hoisting cable head sheave place on the derrick; The revolution of hoisting cable sky wheel shaft in the detection, this revolution promptly reflect velocity of rotation and the direction of hoisting cable on head sheave; Following hoisting cable head sheave shaft encoder 2 is installed in the following hoisting cable head sheave place on the derrick, detects the revolution of hoisting cable sky wheel shaft down, and this revolution reflection is velocity of rotation and the direction of hoisting cable on head sheave down; Gig is normally in service; Last hoisting cable sky wheel shaft is identical with following hoisting cable sky wheel shaft velocity of rotation; Direction of rotation the slack rope phenomenon occurs when last hoisting cable or when down hoisting cable is transferred, and the sky wheel shaft velocity of rotation of then transferring rope is with slack-off; So that stop operating, become tangible contrast with the sky wheel shaft velocity of rotation of the rope that rises; At this moment, PLC programmable logic controller (PLC) 3 passes through last hoisting cable head sheave shaft encoder 1, and the acquisition of signal of following hoisting cable head sheave shaft encoder 2 is through calculating, discern, can judging whether the slack rope phenomenon has taken place.As the slack rope phenomenon has taken place, this device will make sound device 5 send the slack rope audio alarm, simultaneously normally closed contact 6 broken off, and cut off the safety return circuit of gig, make gig realize safety arrestment.
This device accuracy rate is high, accuracy of judgement, and maintenance capacity is little, and is not fragile.Said normally closed contact 6 seals in the mine hoist safety loop.
