Description
Technical field:
the utility model belongs to the technical field of belt conveyors, and particularly relates to a non-contact belt deviation and longitudinal tearing protection device.
The background technology is as follows:
The belt conveyor has the characteristics of large conveying capacity, long conveying distance, high efficiency, continuous transportation, safe work, small noise and the like, and becomes one of the main underground transportation equipment of coal mines in China. In the working process of the belt conveyor, the material is unevenly distributed, so that the conveying belt is easy to deviate; in addition, some large raw coal and the like mixed in the materials have sharp corners, and the conveying belt is easily scratched or pierced in the conveying process, so that the tearing phenomenon occurs. When the belt conveyor is deviated or the belt surface is torn, equipment damage, product waste and even dangerous accidents can be caused. Therefore, the installation and use of the deviation protection device and the longitudinal tearing protection device are important to ensure the normal operation of the belt conveyor and the safety of personnel.
Some existing deviation protection devices used by the belt conveyor apply contact switches, such as CN217731750U, and deviation protection rods are arranged on two sides of the belt, so that due to the complex running environment of the coal conveyor, interference factors, such as sundries or foreign matters, can occur to touch the deviation switch, so that false alarm can be caused, and unnecessary shutdown or other operations can be caused; moreover, when the deviation degree of the belt does not reach the early warning value, the belt and the protection rod are rubbed with each other, so that the belt is damaged, the protection rod is damaged, the contact switch is invalid after a long time, and further, the alarm cannot be timely given out, and larger equipment damage is generated. The existing belt conveyor belt surface is always in an overlapped state after being torn, materials cannot be immediately scattered to the lower side of the belt, but a traditional longitudinal tearing protection device such as CN201780381U sends out an alarm after detecting that the torn materials fall down, at the moment, the belt surface of the whole belt conveyor is always completely torn, the expansion of a belt surface tearing accident cannot be avoided, and serious belt damage and material loss are caused.
The utility model comprises the following steps:
The utility model aims to provide a non-contact belt deviation and longitudinal tearing protection device so as to solve the problems.
The utility model is implemented by the following technical scheme:
the non-contact belt deviation and longitudinal tearing protection device comprises a frame of a belt conveyor, a belt, a controller, an alarm device and a belt conveyor motor stopping device; a fixing frame is fixed above the frame; the machine frames on two sides of the belt are respectively provided with a first-stage deviation infrared receiver, and the fixing frame is provided with a first-stage deviation infrared emitter corresponding to the first-stage deviation infrared receiver; two longitudinal tearing infrared receivers are arranged on the frame, and the side surface, away from the other longitudinal tearing infrared receiver, of the longitudinal tearing infrared receiver is flush with the side surface of the belt; a longitudinal tearing infrared emitter corresponding to the longitudinal tearing infrared receiver is arranged on the fixing frame; the signal output end of the first-stage deviation infrared receiver and the signal output end of the longitudinal tearing infrared receiver are respectively connected with the signal input end of the controller through signals; the signal output end of the controller is respectively connected with the signal input ends of the alarm device and the belt conveyor motor shut-down device through signals.
When the belt is deviated, signals transmitted by the first-stage deviation infrared transmitter to the first-stage deviation infrared receiver are blocked, the first-stage deviation infrared receiver transmits alarm signals and shutdown signals to the controller, the controller processes the alarm signals and transmits the alarm signals to the alarm device, and the controller processes the shutdown signals and transmits the processed signals to the motor shutdown device of the belt conveyor, so that the alarm after the belt is deviated and the belt conveyor is shut down. When the belt is longitudinally torn, the width of the belt is narrowed, so that an infrared signal sent by the longitudinal tearing infrared transmitter is received by the longitudinal tearing infrared receiver, the longitudinal tearing infrared receiver sends an alarm signal and a shutdown signal to the controller, and after receiving the signals of the two longitudinal tearing infrared receivers, the controller carries out corresponding processing and sends the alarm signal to the alarm device and sends the shutdown signal to the motor shutdown device of the belt conveyor, so that the alarm after the belt is longitudinally torn and the belt conveyor is shut down.
Further, a secondary deviation infrared receiver is arranged on the rack between the primary deviation infrared receiver and the longitudinal tearing infrared receiver, and a secondary deviation infrared emitter corresponding to the secondary deviation infrared receiver is arranged on the fixing rack; and the signal output end of the secondary deviation infrared receiver is connected with the signal input end of the controller through a signal. When the belt is deviated, the deviation degree does not lead to blocking the signal emitted by the first-stage deviation infrared emitter to the first-stage deviation infrared receiver, only slight deviation leads to blocking the infrared signal emitted by the second-stage deviation infrared emitter to the second-stage deviation infrared receiver, the second-stage deviation infrared receiver sends an alarm signal to the controller, and the controller processes the alarm signal and sends the alarm signal to the alarm device to realize the alarm after the belt is slightly deviated. The belt is arranged in such a way that when the belt is slightly deviated, the alarming device reminds a worker to carry out corresponding adjustment without directly shutting down the belt conveyor, if the worker does not carry out effective adjustment, the belt continuously deviates, so that signals emitted from the first-level deviation infrared emitter to the first-level deviation infrared receiver are blocked, and the belt conveyor is automatically shut down.
Further, the alarm device at least comprises one or more of an audible and visual alarm, an indicator light, a buzzer and a loudspeaker.
The utility model has the advantages that:
The utility model provides a non-contact belt deviation and longitudinal tearing protection device aiming at the problems of deviation or longitudinal tearing of a belt conveyor, which can timely give an alarm and shut down the belt conveyor when the belt is deviated or longitudinally torn by arranging an infrared transmitter and an infrared receiver which are in one-to-one correspondence, so as to reduce equipment damage, material loss and the like caused by the belt deviation or the longitudinal tearing of a belt surface, ensure the operation safety of the belt conveyor, prolong the service life of the belt, reduce the replacement times of the belt and lighten the labor intensity of workers. In addition, the two-stage infrared device is arranged, the operation of alarming or alarming and closing can be performed according to the deviation degree of the belt, the running efficiency of the belt conveyor can not be affected by slight deviation, and the stability of the belt conveyor is guaranteed.
