Abstract
The utility model provides a device for automatically stopping when a hopper of a belt conveyor is blocked and materials overflow the hopper, and belongs to the technical field of belt conveyors. The device is used for implementing automatic stopping protection when the hopper of the belt conveyor is blocked and the materials overflow the hopper. According to the technical scheme, the device is composed of a movable slab door, a limiting switch and a fixed support. A material leakage opening is formed in the lower portion of the side face of the discharge hopper of the conveyor head of the belt conveyor, the movable slab door covers the material leakage opening, one side of the movable slab door is installed on the discharge hopper of the conveyor head through hinges, the limiting switch is installed on the outer wall, relative to the other side of the movable slab door, of the discharge hopper of the conveyor head, a limiting switch roller is pressed at the edge of the movable slab door, and a limiting switch circuit is connected with a stopping control circuit or a deviation control circuit. The device is simple in structure, convenient to use, high in sensitivity, safe and reliable, the accidents that the hopper of the belt conveyor is blocked and the materials overflow can be avoided, the accidents can be prevented from being further expanded, long-time overhaul is avoided, maintenance time is reduced, cost is saved, and the device has remarkable economic benefits.
Description
Technical field
The utility model relates to a kind of belt conveyer funnel blockade, the self-stopping fender guard of flash, belongs to the belt conveyer technical field.
Background technology
Belt conveyer is as continuous loose unpacked material Transport Machinery, be widely used in the industries such as metallurgy, colliery, power plant, grain building materials, it is compared with other transportation devices (as the locomotive class), not only there is the advantages such as long distance, large conveying quantity, continuous conveying, and reliable, easily be automated, centralization controls.Commercial production transit link complexity, require the belt conveyer time of run longer, operation factor is high, belt conveyer in operational process because sideslip often appears in all factors, the fault such as skid, due to the relation of material properties, as large as moisture, viscosity contains foreign material etc. greatly and in material, normal funnel blockade, the flash of occurring, even rub the accidents such as belt, once rub belt, again glueing joint and resuming production at least needs tens hours, and these accidents have had a strong impact on carrying out smoothly of producing.Although preventing having taked some measures aspect the belt conveyer funnel blockade in recent years, effect is unsatisfactory in actual use, therefore, take that practicable anti-funnel stops up, the flash technology is very necessary.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of belt conveyer funnel blockade, flash automatic stopping device, this automatic stopping device input is little, effect is remarkable, can stop belt conveyer funnel blockade, flash and even rub the serious accident generations such as belt.
The technical scheme solved the problems of the technologies described above is:
A kind of belt conveyer funnel blockade, the flash automatic stopping device, it is by the portable plate door, limit switch and fixed support form, the position on the lower, side of belt conveying machine head blanking funnel has Lou material mouthful, the portable plate door covers Lou expects on mouth, be positioned at the lateral surface that leaks the material mouth, one side of portable plate door is arranged under head on funnel by hinge, on the outer wall of funnel, limit switch is installed under the head relative with the opposite side of portable plate door, the limit switch roller compression is on the edge of portable plate door, the limit switch circuit is connected with parking control path or the camber control circuit of belt conveyer.
Above-mentioned belt conveyer funnel blockade, flash automatic stopping device, described limit switch is arranged on fixed support, and fixed support is weldingly fixed under head on funnel.
Above-mentioned belt conveyer funnel blockade, flash automatic stopping device, described portable plate door bottom is welded with clump weight.
The beneficial effects of the utility model are:
Portable plate door of the present utility model when belt normally moves transported material in closed condition, the limit switch roller is close to dodge gate, if belt conveyer head funnel blockade, when material position in funnel rises to the dodge gate place, dodge gate is produced to pressure, make it outer support one small distance, thereby drive the fork action of limit switch, signal feedback, to parking control path or camber control circuit, stops belt feeder.The utility model is simple in structure, easy to use, highly sensitive, safe and reliable, can prevent the further expansion of belt conveyer funnel blockade, flash accident and accident, avoid long maintenance, reduce maintenance time, save expense, there is significant economic benefit.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: funnel 3, hinge 4, portable plate door 5, limit switch roller 6, limit switch fork 7, limit switch 8, fixed support 9, limit switch circuit 10 under belt 1, head guard shield 2, head.
The specific embodiment
The utility model is comprised of hinge 4, portable plate door 5, limit switch 8, fixed support 9.
In figure, show, the position on the lower, side of belt conveying machine head blanking funnel has Lou material mouthful, and it is mouthful upper that portable plate door 5 covers material with Louing, is positioned at the lateral surface that leaks the material mouth, portable plate door 5 from belt away from a side by hinge 4, be arranged under head on funnel 3.The position that portable plate door 5 is opened is in the situation that allow more low better, makes that funnel 3 under head stops up, automatic train stop the earliest while rising on the material position.
In figure, show, on the outer wall of funnel 3, limit switch 8 is installed under the relative head of the side of opening the door of portable plate door 5, limit switch 8 is arranged on fixed support 9, and fixed support 9 is weldingly fixed under head on funnel 3.
In figure, show, limit switch roller 6 is pressed on the edge of portable plate door 5, when portable plate door 5 is opened because of material impact, drives 7 actions of limit switch fork.Limit switch circuit 10 is connected with parking control path or the camber control circuit of belt conveyer.
In figure, show, because funnel under head 3 has certain angle of inclination downwards, because gravity factor oneself is opened, can weld the clump weight of suitable weight in portable plate door 5 bottoms, during with assurance belt open drive, limit switch 8 can be because of gravity or vibrations action parking voluntarily, clump weight can not be overweight simultaneously, to guarantee portable plate door 5, opens the sensitivity that touches limit switch fork 7.
Working process of the present utility model is as follows:
In belt 1 normal operation convey materials process, portable plate door 5 is normally closed.
When under head, funnel 3 stops up, material section is within it piled up, on position, rise, once the height risen to over portable plate door 5, material produces pressure to portable plate door 5 opens door, drive 7 actions of limit switch fork when portable plate door 5 is opened, limit switch 8 signal feedback, to parking control path or camber control circuit, stop belt voluntarily.
Embodiment of the utility model is as follows:
At belt conveying machine head blanking funnel 3 side opening square holes, utilize the steel plate of cutting off to utilize hinge 4 to be fixed on lower funnel 3 as portable plate door 5.
Limit switch 8 adopts the small-sized limit switch WLCA2-2N of Omron OMRON.
Fixed support 9 adopts funnel 3 under the long ∠ 50mm * 50mm of 200mm * 3mm angle steel and head to be welded and fixed.
