Abstract
An alarm protection device used for preventing a conveyor belt from tearing or being blocked comprises a discharge hopper and the conveyor belt. The alarm protection device is characterized in that an inclined partition plate with one high end and one low end is designed between the position below a discharge outlet of the discharge hopper and the surface of the conveyor belt, the two ends of the partition plate are suspended on a support of the discharge hopper through four elastic pull rods with protective covers, an anti-abrasion belt is fixed to the surface of the partition plate, a vibration motor is installed at the high end of the partition plate, and when the vibration motor operates, the partition plate and the anti-abrasion belt of the partition plate can vibrate continuously for feeding. The alarm protection device is simple in structure, the belt can be protected against damage by means of the partition plate, enterprise fund waste and time waste caused by frequent belt replacement in the prior art are avoided, automatic alarm and shutdown are achieved when the belt tears or is blocked, safety production is facilitated, and major safety accidents are avoided.
Description
Technical field
The present invention is a kind of alarm protecting apparatus of, Anti-blockage anti-tear for transmission belt, belongs to material tranmission techniques field.
Background technology
Due to the needs that automatization level improves and produces, material is transmitted long-standing by belt conveyor, and particularly at coal, mineral products, smelt, thermal electric generation, and the sector applications such as building materials are more extensive.In real work, the material that belt transmits, in belt is sent to material-falling hopper, crosses material-falling hopper and again transmits by next belt conveyor.In order to prevent material-falling hopper wearing and tearing, in material-falling hopper inwall surrounding, liner plate has been installed, due to liner plate long term wear, fixedly sieve silk of liner plate will wear and tear and come off, and monoblock liner plate will drop on the belt of material-falling hopper, makes belt tearing; Though existing, have device for detecting belt tearing, it is passive detection, and phenomenon still often appears tearing in belt.Belt after tearing must be shut down replacing; otherwise cannot normally produce, a belt is worth wants several units up to a million that pick up, and changing enterprise should affect production by waste money at every turn again; so how to solve the problem of belt tearing, it is the difficult problem that each enterprise and R&D institution study and capture always.
Summary of the invention
A difficult problem of easily tearing normal putty for overcoming existing belt conveyor transmission belt; the invention provides a kind of alarm protecting apparatus of, Anti-blockage anti-tear for transmission belt; in order to extend the service life of transmission belt, reduce use cost, improve the service efficiency of belt conveyor.
For solving its technical matters, the technical solution used in the present invention is: the present invention is that contriver has carried out observation, analysis and the research after for many years to the structure of belt conveyor and service condition, finally find and produce transmission belt and tear the immediate cause with putty, material directly contacts with belt, and solution is isolated exactly.Thereby complete the present invention.The alarm protecting apparatus of, the Anti-blockage anti-tear for transmission belt of designing, comprise: hopper and transmission belt, its feature is: below the discharging opening of hopper and between transmission belt surface, be designed with the division board of one end high other end low dip formula, the two ends of this division board are by four with protecting cover elastic draw bars, and hanging is on the support of hopper; On the surface of division board, be fixed with abrasionproof belt; On the division board of higher one end, the motor that shakes is installed, when shaking machine operation, this can make the vibration continuously together of division board and abrasionproof belt thereof, play feeding effect.Below the division board of higher-end, on support, limit switch is installed, division board can decline because of overweight, and when limit switch is encountered in division board decline, this limit switch can stop belt work by automatic alarm.Described limit switch is travel switch or photoelectric switch.
Compared with prior art, the present invention has following features and progress:
1, between the discharging opening and transmission belt surface due to the hopper of belt conveyor, be designed with tilting division board, during conveyer work, material does not directly drop on belt, but drop on division board, if there is the article of easy damage belt or the liner plate Shi Buhui that comes off to damage belt in material, only can damage division board, thereby play the effect of protection belt;
2, on tilting division board surface, be fixed with abrasionproof belt, be conducive to extend the service life of division board, when division board contingency is damaged, also only need to change the belt on division board, without replacing transmission belt, can save a large sum of service expenditure and time;
3, owing to installing by limit switch or photoelectric switch below division board; in material, have when damaging the article of belt or liner plate and coming off; form putty; elastic draw bar can make division board encounter limit switch; control circuit meeting automatic alarm also stops belt-driving, if after the interior putty of material-falling hopper, division board is encountered limit switch because load-bearing is excessive; control circuit also can stop belt by automatic alarm, thereby play protection belt, prevents the effect of tearing and blocking alarming is shut down.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, hopper, 2, division board, 3. abrasionproof belt, 4, with protecting cover elastic draw bar, 5, vibrating motor, 6, limit switch, 7, transmission belt.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
With reference to accompanying drawing, the alarm protecting apparatus of, the Anti-blockage anti-tear for transmission belt of designing, comprise: hopper 1 and transmission belt 7, its feature is: below the discharging opening of hopper 1 and between transmission belt 7 surfaces, be designed with the division board 2 of one end high other end low dip formula, the two ends of this division board are by four with protecting cover elastic draw bars 4, and hanging is on the support of hopper 1; On the surface of division board 2, be fixed with abrasionproof belt 3; On the division board 1 of higher one end, vibrating motor 5 is installed, during this vibrating motor work, can makes the vibration continuously together of division board and abrasionproof belt thereof; Below the division board 1 of higher-end, on support, limit switch or photoelectric switch 6 are installed, division board falls because of liner plate; Putty is overweight can decline, when division board declines while encountering limit switch or during photoelectric switch, this limit switch can stop belt work by automatic alarm.Wherein said limit switch is travel switch or photoelectric switch.
Claims (3)
1. the alarm protecting apparatus of a, Anti-blockage anti-tear for transmission belt, comprise: hopper and transmission belt, it is characterized in that: below the discharging opening of hopper and between transmission belt surface, be designed with the division board of one end high other end low dip formula, the two ends of this division board are by four with protecting cover elastic draw bars, and hanging is on the support of hopper; On the surface of division board, be fixed with abrasionproof belt; On the division board of higher one end, the motor that shakes is installed, when shaking machine operation, this can make the vibration continuously together of division board and abrasionproof belt thereof, play feeding effect.
