Abstract
The utility model discloses a whole-course safe device against a slack rope and belongs to the technical field of mine facilities. The device comprises a parallel bar laid on the wall of a vertical shaft and composed of multiple parallel reed switches, magnetic steel which is installed on the lateral side of a cage and corresponds to the parallel bar, and an encoder installed on a main shaft of a roller of a lifter, wherein the cage is connected with the roller through a lifting steel wire rope via a head sheave, the encoder and the reed switches are connected with a PLC through transmission lines, and the PLC controller is connected with a display and an alarm through transmission lines. According to the device, whole-course protection against the slack rope is realized, and the technical problem of poor safety existing in the prior art is solved.
Description
technical fieldthe utility model belongs to mine facility technical field, is specifically related to a kind of omnidistance rope-loosing protection device.
background technologymine hoist is in operation, and due to the impact of various factors, produces sometimes the abnormal condition such as card tank, thereby hoisting cable slack rope accident occurs, and now as not in time stops, and likely causes serious accident of cage crashing.For this reason, code regulation, cylindrical drum hoist should be installed rope-loosing protection device.
summary of the inventionthe purpose of this utility model is the technical matters that solution prior art exists poor stability, provides a kind of omnidistance rope-loosing protection device, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of omnidistance rope-loosing protection device of the utility model, it is characterized in that it comprise on the vertical shaft wall that is laid in, formed by the reed switch of some parallel connections and bracing, be arranged on the cage side magnet steel corresponding with bracing also and be arranged on the coder on elevator drum main shaft; Described cage is connected with cylinder by head sheave by hoisting cable; Described coder, reed switch are connected with PLC controller by transmission line respectively, and PLC controller is connected with telltale and annunciator by transmission line.
In the time that gig moves, cylinder drives cage to move up and down by steel rope through head sheave, magnet steel is along with the up-and-down movement of cage, and up-and-down movement, thereby connect successively reed switch, this on-off signal, send into PLC controller through conversion process, the signal of getting with the coder being arranged on the elevator drum main shaft processing that compares, as synchronous in two signal range abilities, gig normal operation, as asynchronous in two signal range abilities, explanation may have slack rope phenomenon to occur, thereby sends sound and light alarm signal and cut off safety return circuit.
The utility model realized omnidistance rope creep protection, solved prior art and exist the technical matters of poor stability.
brief description of the drawingsaccompanying drawing is the utility model structural representation.
In figure 1, reed switch 2 bracing 3, magnet steel 4, cage 5, hoisting cable 6, head sheave 7, cylinder 8, coder 9, PLC controller 10, telltale 11, annunciator
detailed description of the inventionwith reference to accompanying drawing, the utility model it comprise on the vertical shaft wall that is laid in, formed by the reed switch 1 of some parallel connections and bracing 2, be arranged on the cage 4 sides magnet steel 3 corresponding with bracing 2 also and be arranged on the coder 8 on elevator drum 7 main shafts; Described cage 4 is connected with cylinder 7 by head sheave 6 by hoisting cable 5; Described coder 8, reed switch 1 are connected with PLC controller 9 by transmission line respectively, and PLC controller 9 is connected with telltale 10 and annunciator 11 by transmission line.
The omnidistance rope-loosing protection device of the utility model, in the time that gig moves, cylinder 7 drives cage 4 to move up and down by hoisting cable 5 through head sheave 6, and magnet steel 3 is along with the up-and-down movement of cage 4, and up-and-down movement; Thereby connect successively reed switch, this on-off signal, send into PLC controller 9 through conversion process, the signal of getting with the coder 8 being arranged on the elevator drum 7 main shafts processing that compares, as synchronous in two signal range abilities, gig normal operation, as asynchronous in two signal range abilities, explanation may have slack rope phenomenon to occur, thereby sends sound and light alarm signal and cut off safety return circuit.
