Abstract
The utility model discloses a broken-belt protector for a belt conveyer, relates to the technical field of conveyers, and comprises an explosion proof type control cabinet, a plurality of broken-belt protecting mechanisms connected with the explosion proof type control cabinet, and an explosion proof sensor connected with the explosion proof type control cabinet for detecting broken-belt information. The broken-belt protector for the belt conveyer has the advantages that reliable judgment is achieved when broken-belt accidents happen, and when a broken-belt accident is judged, the plurality of broken-belt protecting mechanisms produce synchronous brake operations, so that stalling belts are stopped and huge loss to a mine caused by broken belts is avoided.
Description
Technical field
The utility model relates to the belt conveyer technical field, specifically is that a kind of belt conveyer is arrested device with broken belt, is mainly used in arresting to the judgement of belt conveyer generation broken belt and after broken belt takes place.
Background technology
Belt conveyer is widely used in the mine transportation, be dangerous accident and the loss that prevents that broken belt from causing, broken belt generally is installed on belt conveyer is arrested device, broken belt is arrested device and generally is made up of the broken belt testing agency and several broken belt arresting agencies that are installed on the belt conveyer that keep at a certain distance away, and generally is that interval 100 meter amperes are adorned a broken belt arresting agency.The broken belt arresting agency is made up of down slipper and last slipper, and following slipper is installed near below the load-transfer device, goes up when broken belt takes place that slipper moves and following slipper is caught load-transfer device together.At present, the broken belt arresting agency that the known broken belt that grew up is in recent years arrested device is that hydraulic gear is carried out action, and that hydraulic gear has a cost is too high, shortcoming difficult in maintenance, in case leakage of oil or pipelines from bursting accident take place, can not effectively arrest, cause damage to the user.In addition, broken belt arresting agency at interval 100 meter amperes is adorned one, broken belt takes place after, even arrest action, because of the broken belt place apart from the arresting agency hypertelorism, very easily cause the unrestrained obstruction of a large amount of coals or ore tunnel.Known Purely mechanical broken belt is arrested device, when the broken belt fault takes place, can not carry out fast and reliable ground arrests synchronously, that promptly can not keep strokes arrests, a part of broken belt arresting agency action often takes place, cause in the process of arresting belt can tear or secondary breakdown, cause damage to the user.
Summary of the invention
Arrest the deficiency of device in order to overcome existing broken belt, the utility model provides a kind of belt conveyer to arrest device with broken belt, can not only failure-free judges the broken belt fault, and arresting simultaneously and rapidly when can failure-free carrying out conveyor belt breakage.
The utility model is realized with following technical scheme: a kind of belt conveyer is arrested device with broken belt, comprise the some broken belt arresting agencies that are installed on the load-transfer device, the sensor of online detection load-transfer device situation, explosion-proof control box, in explosion-proof control box controller PLC is arranged, sensor is connected the signal conveys that will gather to controller PLC with controller PLC; Described broken belt arresting agency is made up of last slipper, following slipper and actuating unit, and actuating unit is installed on the slipper; Described actuating unit adopts electromagnetic actuator, and each electromagnetic actuator all is connected with controller PLC in the explosion-proof control box.
Principle of work: the controller PLC that the status information that sensor moves the load-transfer device that collects is sent in the explosion-proof control box is handled, after being judged as broken belt, controller PLC is passed to a plurality of broken belt arresting agencies to speed-slackening signal, and broken belt arresting agency synchronization action is braked and stopped belt and moves.
The beneficial effects of the utility model are: the reliable judgement when having realized belt conveyer generation broken belt accident, reliable braking, the massive losses of having avoided load-transfer device fracture back to cause to mine.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 broken belt actuating unit structural representation.
Among the figure: 1, load-transfer device, 2, sensor, 3, explosion-proof control box, 4, the broken belt arresting agency; 41, actuating unit, 411, magnet coil, 412, explosion-resistant enclosure, 413, flexible iron core, 42, go up slipper, 43, slipper down, 5, start button; 6, reset button.
The specific embodiment
As shown in Figure 1, belt conveyer is arrested device with broken belt and is comprised the some broken belt arresting agencies 4 that are installed on the load-transfer device 1, the broken belt arresting agency 4 of a plurality of braking belts overcomes coal unrestrained when broken belt takes place or ore and stops up the tunnel along 30 meters-50 meters rectangular distributions in load-transfer device interval; The sensor 2 of online detection load-transfer device 1 situation, explosion-proof control box 3 has controller PLC in explosion-proof control box 3, sensor 2 and controller PLC adopt cable connection with the signal conveys of gathering to controller PLC; Broken belt arresting agency 4 is made up of last slipper 42, following slipper 43 and actuating unit 41, and actuating unit 41 is installed on the slipper 42; Described actuating unit 41 adopts electromagnetic actuator shown in Figure 2, by the applicant's patent applied for.Each electromagnetic actuator all is connected with controller PLC in the explosion-proof control box 3.On explosion-proof control box 3, be equipped with and comprise start button 5 and reset button 6; Start button 5 is connected with the input signal terminal of explosion-proof control box with reset button 6, and broken belt arresting agency 1 is connected with the output interface of explosion-proof control box.
As shown in Figure 2, actuating unit 41 is formed by the explosion-resistant enclosure 412 of magnet coil 411, Motionless electromagnetic coil with at the flexible iron core 413 that the execution of magnet coil central authorities is moved.Magnet coil is fixed in the explosion-resistant enclosure 412.Flexible iron core was withdrawn opening time less than 0.5 second.Installation method is: open the groove that cooperates with flexible iron core on last slipper 42, the head of flexible iron core gos deep in the groove, when magnet coil 411 when electric, produce magnetic field, flexible iron core is sucked in magnet coil 411 by magnetic field, and last slipper 42 actions and following slipper are pushed down load-transfer device together.Also can be as shown in Figure 2, with flexible iron core place slipper 42 below, when magnet coil 411 when electric, produce magnetic field, flexible iron core is sucked in magnet coil 411 by magnetic field, last slipper 42 moves and following slipper is pushed down load-transfer device together.
Control step: press start button 5 and enter starting state, detect the sensor 2 of broken belt information the operating state signal of belt is passed to explosion-proof control box 3, after being judged as broken belt, explosion-proof control box 3 is passed to a plurality of broken belt arresting agencies 1 to speed-slackening signal, the coil of actuating unit gets the iron core withdrawal of will stretching after electric, the broken belt arresting agency will be gone up slipper by elastic force and throw away, the braking belt.Broken belt arresting agency 1 synchronization action is braked and is stopped belt and moves.
