Description

Colliery cross line pipe accuse is apart from device Technical Field The utility model relates to the technical field of coal mining, in particular to a coal mine crossing line pipe distance control device. Background When the underground coal mine drainage pipeline and the communication cable are vertically crossed, a safety distance of at least 300mm is required to be maintained. The gas (the main component is methane) discharged by the drainage pipeline is inflammable and explosive, if the communication cable generates electric sparks due to insulation, machinery or short circuit in the vertical crossing process, the distance is Yi Yinran gas too close, the ignition probability can be reduced at the interval of 300mm, and the explosion is prevented. Meanwhile, when the pipeline conveys high-temperature gas or a fire disaster occurs, the distance can delay heat transfer to the cable, the insulation layer is prevented from melting and igniting, time is strived for emergency treatment, the two are prevented from being damaged simultaneously due to construction collision, and the risk of composite faults is reduced. However, it is difficult to secure such a safe distance in practical operation. On the one hand, the underground construction environment is complex, the pumping pipeline and the communication cable are installed by different construction teams, the personnel level and experience difference are large, the measurement and the installation are easy to be irregular, and the actual distance deviates from the safety requirement. On the other hand, the underground device is lack of special fixing and positioning devices for the distance between the underground device and the communication cable when the underground device is vertically crossed, the communication cable is pulled by external force to easily approach the pipeline, and the communication cable is prevented by the supporting-free positioning structure, so that the safety risk is increased. Disclosure of utility model The utility model aims to provide a coal mine cross line pipe distance control device which can accurately and stably maintain the safety distance between a drainage pipeline vertically crossed in a coal mine and a communication cable, effectively prevent safety accidents caused by too close distance, reduce electromagnetic interference and ensure the stable operation of a communication system. In order to achieve the purpose, the utility model provides a coal mine crossing line pipe distance control device which is arranged between a vertically crossed drainage pipeline and a communication cable; the support frame comprises a support rod which is arranged in parallel with the drawing and placing pipeline, and a communication cable is supported at the bottom of the support rod. After adopting above-mentioned structure, through this management and control apart from device of installation between perpendicular crisscross drainage pipeline and communication cable, utilize the gallows to hang in drainage pipeline bottom, the spacer rod downwardly extending, the structural design of support frame support communication cable can effectively ensure to take out and put and keep 300 mm's safe distance between pipeline and the communication cable. The risk that the communication cable generates electric spark to ignite gas to cause explosion due to too close distance is greatly reduced, meanwhile, the heat can be prevented from being quickly transferred to the cable when the pipeline is used for conveying high-temperature gas or a fire disaster occurs, the cable insulating layer is prevented from melting and igniting, the time is strived for emergency treatment, the probability that the two are damaged simultaneously due to construction collision can be reduced, the risk of composite faults is reduced, and the safety of underground operation of a coal mine and the stability of a communication system are guaranteed.
