Description
Technical Field
The utility model relates to the field of detection devices of materials, in particular to a detection device for detecting deviation and overflow of an adhesive tape and puncture damage and tearing of foreign matters of various adhesive tapes on line, which is applied to a bearing type adhesive tape conveyor.
Background
At present, a bearing type adhesive tape conveyor (abbreviated as an adhesive tape machine) is often used in daily production operation of enterprises such as metallurgy, coal, ports, power generation and the like, more than 1000 adhesive tape machines are used daily by taking an iron works as an example, the adhesive tape machines have the characteristics of wide tape width, high speed, large conveying capacity and the like, a computer automatic operation control technology is adopted in a conveying system, a series of equipment fault detection and safety protection devices such as an adhesive tape machine deviation detection device, a slipping detection device, a chute blockage detection device and the like are additionally arranged on the adhesive tape machines, and once the adhesive tape machines have faults such as deviation, slipping or chute blockage and the like, the adhesive tape machines can be timely detected, found and stopped, so that a great amount of material overflows and equipment damage are avoided, and the safety, stability and continuous smooth operation of production and equipment are ensured.
However, it has been found from the summary and feedback of long-term production experience of field workers that the productivity of the adhesive tape machine equipment is severely tested due to the degradation of raw fuel and the continuous improvement of the delivery workload, and the conventional protection device of the adhesive tape machine in the prior art has not satisfied the requirement of developing the production situation, resulting in various situations, such as:
1) Various sharp metal or nonmetal foreign matters are sometimes mixed in the material, and in the unloading process of the material, the conveyer belt of the lower belt conveyor is pricked along with the falling of the material, so that the belt is torn, and the conveyer belt is greatly worn along with the increase of the tearing opening, so that even fire accidents can be finally caused, and the normal operation of an equipment system is greatly influenced;
2) Although the deviation detector is arranged under the prior art, in the actual operation of the adhesive tape machine, deviation alarm is frequently generated when the material is poured at the blanking point of the upstream equipment, but the situation of material overflow is generated, so that a large amount of overflowed material is accumulated at the tail part or the buffer part of the adhesive tape, and further potential safety hazard is caused.
Therefore, how to accurately detect the tearing or deviation of the overflow caused by the foreign matters penetrating through the belt in time is an urgent problem to be solved.
The prior art also makes efforts to solve the above problems, such as "a conveyor belt surface image acquisition and analysis device" and "a curtain-shaped anti-tearing net device for a belt conveyor", but the existing defects of the curtain-shaped anti-tearing net device are found in practical application by field workers, so that the curtain-shaped anti-tearing net device cannot be popularized and applied in a large area, and the specific situations are as follows:
1) The device is mainly used for acquiring the surface image of the conveyor belt in real time in the belt running process, so that the real-time image of the conveyor belt surface acquired by the device can be remotely transmitted to an upper image server for storage, display, analysis, processing and the like. The real-time images, the historical images and the like of the surface of the conveying belt stored by the image server are identified, analyzed and processed, the defects of the conveying belt are further judged, the specific positions of the defects and the defect development process are further judged, the degradation trend of the use state of the belt is mastered in real time, and the functions of fault alarming and the like can be performed on the serious defects of the surface of the conveying belt.
Although the detection effect of the technology is better, the technology is put into test use on a plurality of production lines, one huge problem is that the cost is high, the cost of a single set of equipment is more than 10 ten thousand yuan, a plurality of sets of equipment can be arranged on one line, and due to the problem of pollution of the working environment of the adhesive tape conveyor, the detection and identification device needs to be cleaned, maintained and replaced from time to time, if the detection and identification device is popularized to all 1000 adhesive tape machines of an iron-making plant, the high cost is self-evident, and even the cost of periodic replacement is far exceeded.
2) The curtain-shaped adhesive tape tearing prevention net device for the adhesive tape conveyor has been tested on site in 2010 at an iron works, and is overruled after finding that the defect exists, and is not implemented, and the following 3 problems are mainly caused:
2.1 The device is of an integral design, is fixedly arranged between the buffer carrier roller and the buffer carrier roller of the belt conveyor through welding, cannot realize movement, and when foreign matters impact the curtain-shaped anti-adhesive-tape tearing net, the detection device does not drive the detection switch through movement, but drives the whole anti-adhesive-tape tearing net to shrink inwards through strong pulling, so that the anti-tearing net is attached to the non-working surface of the adhesive tape and is rolled into the carrier roller, and the anti-tearing net becomes a disposable consumable after being damaged;
2.2 The phenomenon of scattering materials is unavoidable in the operation process of the adhesive tape, part of materials are clamped between the non-working surface and meshes of the adhesive tape, the granularity of most raw fuel is about 30mm, and under the friction effect of the adhesive tape and the materials, the anti-tearing net can be wound into the bearing roller as well, so that the adhesive tape can be directly damaged;
2.3 The longitudinal steel wires and the transverse steel wires of the device are all soft steel wires, the molding degree is poor, the device is easy to deform, the device is easy to roll into a bearing roller, and the bearing roller and a conveying adhesive tape are damaged.
In summary, in the prior art, a method for timely and accurately detecting tearing or deviation and flash caused by a belt pricked by a foreign object has the problem of high cost or the defect of a detection mode, so that no material overflow detection technology under the condition that a tape machine does not touch the deviation and flash alarm exists at present.
