Abstract
The utility model provides a monitoring device of cable drum running state which characterized in that, at a magnet of cable drum terminal surface installation, and on the rotation orbit of corresponding magnet on the shelf of cable drum axle head, install 2 magnetic force detection switches, magnetic force switch's detected signal conveys the PLC control system of operation equipment. The utility model has the advantages that: because the automatic monitoring device capable of detecting the running state of the winding drum in real time is additionally arranged on the cable winding drum, once a fault caused by a driving device or a transmission mechanism of the cable winding drum occurs, the monitoring device can immediately control the running equipment to stop when the cable winding drum is in an out-of-control state, and the situation that the cable on the cable winding drum is loosened and sagged to roll is prevented, so that economic loss is caused.
Description
Technical Field
The utility model relates to a monitoring device, in particular to monitoring device of cable drum running state.
Background
In industrial production, a torque motor is often used for dragging a cable drum to reel and unwind a cable. However, in the use process, the torque motor drives the cable drum, and the cable drum can be driven to rotate only through links such as chain transmission of the speed reducer or gear transmission, so that the cable is wound and unwound. And in case the driving chain disconnection appears, the cable drum appears out of control, and the cable on the reel can all loosen and take off and scatter to ground under the effect of gravity, and at this moment, in case equipment operation will roll the cable, causes the damage of cable and even breaks, brings very big economic loss.
Disclosure of Invention
The utility model aims at providing a cable drum running state's monitoring device to real-time supervision cable drum's running state, and whether the running state of automatic judgement cable drum is normal, when cable drum appears unusually, control operation equipment parks, in order to avoid taking place the accident that rolls the cable.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a magnet is installed at a proper position of the end face of a cable drum, 2 magnetic force detection switches are installed on a rack at the shaft end of the cable drum on the rotating track of the corresponding magnet, and detection signals of the magnetic force detection switches are transmitted to a PLC control system of running equipment.
The utility model has the advantages that: because the automatic monitoring device capable of detecting the running state of the winding drum in real time is additionally arranged on the cable winding drum, once a fault caused by a driving device or a transmission mechanism of the cable winding drum occurs, the monitoring device can immediately control the running equipment to stop when the cable winding drum is in an out-of-control state, and the situation that the cable on the cable winding drum is loosened and sagged to roll is prevented, so that economic loss is caused.
Drawings
Fig. 1 is an installation and usage schematic diagram of the monitoring device of the present invention.
Fig. 2 is a circuit diagram of the PLC control program when the cable drum is stationary according to the present invention.
Fig. 3 is a circuit diagram of the PLC control program when the cable drum of the present invention is in operation.
Detailed Description
The following describes the specific structure of the monitoring device of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1, it is a schematic view of the installation and use of the monitoring device of the present invention.
A magnet 3 is installed at a proper position of the end face of a cable drum 5, two magnetic force detection switches 1 and 2 are installed on a rack at the shaft end of the cable drum 5 corresponding to the rotation track of the magnet 3, and detection signals of the magnetic force detection switches 1 and 2 are transmitted to a PLC control system of operation equipment.
The utility model discloses a monitoring device's monitoring process divide into two kinds of circumstances:
when the cable drum 5 is at rest, the torque motor is not powered and does not act, and the cable drum 5 is at rest. At this moment, if the driving chain breaks, cable drum 5 can be rotatory by oneself under the action of the gravity of cable 4, and cable 4 pine droops off, and PLC control system can count the magnetic force detection signal that receives automatically, and in order to avoid critical count value unstable, can take count more than 2 after triggering alarm signal again, the PLC procedure under this kind of circumstances is shown in fig. 2.
And (II) when the cable drum 5 runs, the torque motor runs by electrifying, and the cable drum 5 rotates at a constant speed. Firstly, the time value required by the winding drum to rotate for one circle at the fastest speed in a normal operation state is checked. And if the transmission chain is broken when the equipment runs, the time of each circle of the cable drum 5 is shorter than the time collected in advance, at the moment, the running state of the cable drum 5 is judged to be abnormal, and then an alarm signal is triggered. The PLC program in this case is shown in fig. 3.
The alarm signal that PLC program under above two kinds of circumstances sent all can trigger the parking of operation equipment to avoided rolling the occurence of failure of cable 4, reduced the accident rate of equipment.
The utility model has the advantages that: because installed an automatic monitoring device that can real-time detection reel running state additional on cable drum 5, consequently, in case take place because the trouble that drive arrangement or drive mechanism of cable drum 5 arouse, when making cable drum 5 be in the state of out of control, this monitoring device can control the operation equipment parking immediately, prevents that cable 4 on the cable drum 5 from taking off and droing and suffering rolling, causes economic loss.
