Description
Technical field
The utility model relates to a kind of sealing-tape machine arresting stop, relates in particular to the device that a kind of automatic watering stops sealing-tape machine simultaneously.
Background technology
Sealing-tape machine is a very important haulage device in the Coal Production, and can it move safely and efficiently, is directly determining the output and the efficient of mine.Yet in recent years, down-hole sealing-tape machine firing accident constantly takes place.According to miner office statistics, the sealing-tape machine fire incident accounts for 20% of industrial and mineral fire incident.
In order in depth to understand the cause of rubber conveyer fire incident under the coal mine comprehensively, those skilled in the art have carried out a large amount of Field Research and data-searching, by analyzing and summing up, think that the cause of rubber conveyer fire mainly contains 3:
(1) cylinder skids under the normal operation, the slip of the relative cylinder surface of adhesive tape generally is no more than 2%, if adhesive tape skids, then exist bigger relative slip between adhesive tape and the cylinder, and cause friction Temperature Rise, as can not in time finding,, temperature will cause fire in case rising to the adhesive tape ignition temperature.Cylinder skid and be divided into drive roll skid and driven cylinder skid.The reason that common drive roll skids has: the anti-skidding glue serious wear on buy securities with all one's capital back head coal piling, the cylinder, the full load starting after stopping in emergency etc.; The main cause that driven cylinder skids then is that roller bearings is badly damaged or stuck.Skid for drive roll, because of adhesive tape in the process of skidding does not change or rotates very slowly, cylinder continues one section adhesive tape of friction, and then roasting combustion adhesive tape, and adhesive tape will ignite under non-stop-machine operating mode.Skid for driven cylinder, it is very slow that cylinder rotates, even change, and adhesive tape is instantaneous being heated at high-speed cruising, thus be difficult for causing that adhesive tape catches fire when not shutting down, and the adhesive tape that easily after shutdown, ignites very soon.
(2) the carrying roller overtemperature is from finding, in the sealing-tape machine firing accident, and one of main cause that to cause the too high adhesive tape that ignites of carrying roller temperature rise be mining in recent years sealing-tape machine fire owing to carrying roller is stuck.Because the ambient conditions of down-hole is relatively poor, be easy to enter dust in the Idler bearing, the life-span is shorter, after damage of bearings is stuck, adhesive tape will continue friction on the carrying roller surface, make a large amount of heat of carrying roller accumulation, the carrying roller temperature rises to very high, after the parking, actionless adhesive tape continues to contact with stuck high temperature carrying roller, thereby roasting combustion adhesive tape, the coal-fired powder of the beans-and bullets shooter of going forward side by side enlarges the intensity of a fire rapidly.Also finding in the investigation, mainly is that snub pulley does not change and causes that easily adhesive tape catches fire, because snub pulley, particularly near the snub pulley at tail place, carriage is overhead very near, and the coal dust that is very easily scattered on the adhesive tape surrounds, coal piling occurs, cause the radiating condition variation of carrying roller, make stuck carrying roller temperature rise too high.
(3) extraneous burning things which may cause a fire disaster is except the above-mentioned fire that is caused by sealing-tape machine itself, the Another reason that causes the sealing-tape machine fire is extraneous unexpected burning things which may cause a fire disaster, as natural or artificial naked light, wire short-circuiting, down-hole electric substation catch fire, big spoil falls and produces fire by friction below the adhesive tape etc.
Sealing-tape machine is in operation, in case belt takes place to catch fire or the temperature value of overstepping the extreme limit, after then Smoke Sensor in the automatic water system of sealing-tape machine or temperature pick up detected coherent signal, the electromagnetic valve of automatic water system was opened, and the water tap water spray is put out a fire.But, in the prior art, when the automatic water system of sealing-tape machine carries out fire extinguishing water, can't realize that sealing-tape machine shuts down simultaneously.Just, when detecting sealing-tape machine and catch fire, sealing-tape machine can not be out of service immediately, but still move, and is easy to the expansion that enlarges the condition of a fire or cause the accident like this.
Therefore; detecting sealing-tape machine for fear of the automatic water system when sealing-tape machine catches fire when carrying out fire extinguishing water; thereby the phenomenon that sealing-tape machine can not stop to cause fire incident to enlarge immediately takes place, and is necessary to propose a kind of automatic water system and structure of associating of the emergency stop device of sealing-tape machine with sealing-tape machine in fact.
The utility model content
The purpose of this utility model is when proposing a kind of sealing-tape machine and catching fire, and watering stops the device of sealing-tape machine simultaneously automatically, thereby has avoided the further expansion of fire incident.
The purpose of this utility model described above is achieved through the following technical solutions:
A kind of automatic watering stops the device of sealing-tape machine simultaneously, comprises the automatic watering unit of sealing-tape machine and the emergency shutdown unit of sealing-tape machine, and described automatic watering unit is connected with described emergency shutdown unit.
In an embodiment of the present utility model, described automatic watering unit comprises Smoke Sensor unit, control module, watering switch element; Wherein, described Smoke Sensor unit is connected on the described control module, and described control module connects described watering switch element.
In a preferred embodiment of the present utility model, described control module connects described emergency shutdown unit.
In another preferred embodiment of the present utility model, described automatic watering unit also comprises the temperature pick up unit, and described temperature pick up unit is connected on the described control module.
In another preferred embodiment of the present utility model, described watering switch element is an electromagnetic valve.
In another preferred embodiment of the present utility model, described electromagnetic valve is the electromagnetic valve of relay control.
By adopting the technical solution of the utility model described above; can realize following technique effect: when sealing-tape machine catches fire or during belt temperature value of reaching capacity of sealing-tape machine; the automatic watering unit sprinkling fire of sealing-tape machine; thereby the emergency shutdown unit of controlling sealing-tape machine simultaneously stops the operation of sealing-tape machine, has avoided the further expansion of fire incident.
