Description

Coal mine tunneling supporting device Technical Field The utility model relates to the technical field of coal mine tunneling support, in particular to a coal mine tunneling support device. Background Tunneling is the work of digging wells, tunnels and chambers of various shapes, sections or criss-cross in rock strata or ore layers. The tunneling process is divided into a main process and an auxiliary process. The main working procedures are the working procedures of directly finishing the progress of the working face on the working face and the supporting operation carried out in the tunnel tunneling area. The main process is determined by the nature of the rock through which the roadway passes. When the hard rock is tunneled, the main working procedures include drilling, charging, blasting, ventilation, safety inspection of working face, rock charging and roadway support, and when the coal mine is tunneled, the support device is required to be used for protecting personnel. The utility model discloses a coal mine tunneling supporting device, including the protection roof, the protection roof is arc structure, protection roof upper end interlude swing joint has a plurality of buffer, protection roof left end fixedly connected with left mounting bracket, protection roof right-hand member fixedly connected with right mounting bracket, right mounting bracket and left mounting bracket structure are the same, left mounting bracket right-hand member swing joint has left protector, right mounting bracket left end swing joint has right protector, right protector and left protector structure are the same, left mounting bracket lower extreme fixedly connected with left bottom plate, right mounting bracket lower extreme fixedly connected with right bottom plate, the equal fixedly connected with universal wheel in left bottom plate lower extreme front portion and lower extreme rear portion. The installation efficiency is high, supports effectually, and stability is high, is fit for the use of colliery tunnelling. But the device is when using, and the broken stone that the top falls down has the broken stone card in the spring even in the gap between protection roof and contact plate easily, makes buffer's buffering effect reduce even inefficacy, and the stone of blocking is difficult for taking out, and in addition, the spring is rust under the humid environment of heading head easily, influences buffer's life. Therefore, it is necessary to provide a coal mine tunneling support device to solve the above technical problems. Disclosure of utility model Aiming at the situation, in order to overcome the defects in the prior art, the utility model provides the coal mine tunneling support device which can be suitable for being used in a humid environment and is convenient to take out the blocked stone. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides a colliery tunneling supporting device, including protecting the roof, protecting the roof and being the arc, install a plurality of top buffer covers and a plurality of side buffer covers on the protection roof, install a plurality of buffer mechanisms on the protection roof, a plurality of buffer mechanisms are used for respectively between top buffer cover and the protection roof and the side buffer cover is connected between the protection roof, the support frame is installed to the both sides of protection roof, support the protection roof in the construction tunnel of heading through the support frame, make the protection roof protect the tunnel top, buffer mechanism includes the mounting bracket, connecting bolt is installed to the bottom of mounting bracket, install the spacing ring on the connecting bolt, leave enough big gap between mounting bracket and the protection roof, can allow the stone of certain size to pass through, fix the mounting bracket on the protection roof through connecting bolt, the inflatable gasbag is installed at the top of mounting bracket, the gasbag adopts the same connected mode and top buffer cover or side buffer cover, the gasbag is covered by top buffer cover or side buffer cover, and then protect the gasbag. Preferably, the top buffer cover is horizontally installed, the side buffer cover is obliquely installed, the minimum distance between the bottom of the top buffer cover and the protective top plate is smaller than the minimum distance between the mounting frame and the protective top plate, therefore, stone passing through a gap between the top buffer cover and the protective top plate can slide along the top cambered surface of the protective top plate and pass through a gap between the protective top plate and the mounting frame, the side buffer cover is similar to the top buffer cover, and further, the lower side of the side buffer cover is provided with a discharge opening.
