Abstract
A power cable state detection and early warning action device of a port stacker-reclaimer relates to an auxiliary device of the port stacker-reclaimer. The cable-free cable-laying device comprises a frame and rollers, wherein the two rollers are arranged in the frame through roller shafts, and a gap for passing a cable is reserved between the two rollers; the end part of the roller shaft at one side is provided with a metal detection sheet corresponding to the zero-speed switch, and two anti-deviation switches are arranged above the frame. The anti-deviation switch and the zero-speed switch are both connected to a control circuit and/or an alarm device of the stacker-reclaimer. The utility model discloses before triggering the tension limiting and the loose limit switch, can in time stop and report to the police so that the big machine, have the perception accurate, respond sensitively, the timely positive effect of action.
Description
Technical Field
The utility model relates to an auxiliary device of harbour stacker-reclaimer especially belongs to the power cable state detection and the early warning action device of the electrified cable drum of stacker-reclaimer.
Background
The port stacker-reclaimer is a common device in a bulk dry bulk storage yard, and mainly comprises a traveling mechanism, a cable winding mechanism, a rotating mechanism, a pitching mechanism and the like, wherein the cable winding mechanism is a core part of power supply of port equipment and is extremely important to protection of power cables. Adopt among the prior art tension limit and loose limit switch excessively, can take place malfunction alerting and shut down when the cable drum mechanical failure stall or cable slope appear, maintenance personal need put cable, cable winding again, and the recovery process is numerous and diverse, consumes time long, and the operation degree of difficulty is big. If the equipment still walks, the cable can be pulled and broken, and direct economic loss is caused.
Disclosure of Invention
An object of the utility model is to provide a harbour stacker-reclaimer power cable state detects early warning action device promptly to reach and discover early that the cable drum stops soon and cloth cable slope trouble, avoid triggering too tightly spacing and too loose limit switch, be convenient for handle and resume the purpose of normal situation.
The utility model provides a power cable state detection and early warning action device of a port stacker-reclaimer, which is characterized by comprising a frame and rollers, wherein the two rollers are arranged in the frame through roller shafts, and a gap for passing a cable is reserved between the two rollers; the end part of the roller shaft at one side is provided with a metal detection sheet corresponding to a zero-speed switch, and the zero-speed switch is arranged on the frame; two deviation prevention switches are arranged above the frame and symmetrically arranged on two sides of the cable; the anti-deviation switch and the zero-speed switch are connected to a control circuit and/or an alarm device of the stacker-reclaimer.
Furthermore, the frame is arranged on the cable distribution trolley, the two anti-deviation switches move along with the cable distribution trolley correspondingly, and the running position of the cable is within the range of over-tight limit and over-loose limit.
The utility model provides a power cable protection device of harbour stacker-reclaimer electrified cable drum, when cable drum wiring slope, when the cable drum is because of the trouble stall, before triggering tension limiting and cross loose limit switch, can in time shut down and report to the police so that the big machine, it is spacing or tension limiting to avoid the cable to touch the tension, then avoid leading to the big machine to take place serious fault or shut down from this, reduce the maintenance personal and maintain the degree of difficulty of recovering, it is accurate to have the perception, the reaction is sensitive, the timely positive effect of action.
Drawings
The accompanying drawings partially disclose embodiments of the present invention, in which,
fig. 1 is a schematic perspective view of the present invention;
fig. 2 is a schematic view of the installation position of the present invention;
fig. 3 is a schematic view of the action principle of the present invention.
Detailed Description
As shown in fig. 1-3, the utility model provides a harbour stacker-reclaimer power cable state detects early warning action device installs on the middle upper portion of cable laying dolly A, follows the cable laying dolly and removes, including frame 1, gyro wheel 2, two gyro wheels are installed in the frame, leave the clearance of accessible cable b between two gyro wheels, and the gyro wheel rotates smoothly when the cable removes. Wherein, the end part of the outer end of the right roller shaft is provided with a metal detection sheet 3 which rotates along with the roller; a zero-speed switch 4 is installed on the outer side face of the frame, and whether the roller is in a rotating state or not is detected through matching with the metal detection sheet. Two deviation prevention switches 5 are arranged above the framework and symmetrically arranged on two sides of the cable. In the process of moving along with the cable distribution trolley, the running position of the middle cable of the two anti-deviation switches is within the range of over-tight limit and over-loose limit.
Obviously, the deviation prevention switch and the zero-speed switch are connected to a control circuit and/or an alarm device of the stacker-reclaimer, such as a PLC, a control box, an audible and visual alarm and the like.
The above-mentioned deviation-preventing switch is basically the same as the deviation-preventing switch of the belt conveyor system in the prior art, and the zero-speed switch also belongs to the prior art, and the installation and connection thereof are easily thought and can be realized by those skilled in the art, so that the description thereof is not repeated.
In this embodiment, when the cable drum stops due to a fault, the cable stops moving, the roller stops rotating, the metal detection piece mounted at the outer end of the roller shaft stops rotating, and the zero-speed switch transmits a signal of the stop to the PLC after monitoring. Or when the cable inclines and touches the deviation preventing switch, the deviation preventing switch transmits a signal to the PLC. And the PLC receives the signals, and then the large-scale machine is stopped, the alarm is actuated and the fault reason is displayed on the display screen after the judgment, so that the working personnel is reminded to process. And the worker carries out fault elimination according to the fault reason displayed by the display screen, namely, the cable is adjusted or the fault of the cable drum is eliminated. After the fault is eliminated, the staff presses a reset button near the cable drum and then returns to the cab to continue the operation.
