Description

Technical Field

[0001] The utility model relates to the field of coal mine video monitoring, in particular to a video monitoring fixing device for an underground working face in a coal mine. Background Art

[0002] In the process of using existing underground video surveillance in coal mines, angle steel is usually used to weld the camera base in advance, and then the anchor rod and the surveillance are tied and fixed together using wire or bolts on site. There is no special camera fixing device for underground video surveillance in coal mines, especially for mining working faces.

[0003] The camera on the working face is fixed on a wire mesh, and the welded bracket is difficult to connect. The use of wire to fix the monitoring equipment during the installation of underground video surveillance in coal mines is not only prone to wire scratches and eye poking, but also causes material waste. The main reason is that the fixing method is relatively unsafe, and the wire fixation is easy to fall off, which poses a hidden danger to the safety of on-site operations. According to the requirements of relevant documents, the number of monitoring cameras on underground working sites has increased significantly, and there are special installation standards for different conditions and locations. At the same time, the extension or recovery progress of the underground mining working face of coal mines is changing all the time, and the cameras fixed on the roof need to be frequently disassembled, installed, and repaired multiple times, which has caused certain difficulties for the safe production on site. The technical difficulty in solving this problem lies in how to achieve rapid fixing and removal of the camera on the roof, so as to ensure the safe production of the underground coal mine site. Utility Model Content

[0004] The utility model provides a video monitoring fixing device for an underground coal mine working face, which can make the process of disassembling and assembling the top plate of a live camera on the underground coal mine excavation working face more convenient and safer, thereby reducing the risk of accidents during the use of the camera.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 As shown, the utility model provides a video monitoring fixing device for an underground working face in a coal mine, which comprises:

[0030] An anchor rod 1, which is vertically downward and fixed to the top plate 3 of the mining working face by means of an anchor 2;

[0031] A fixed steel pipe 4, which is sleeved on the anchor rod 1 and abuts against the anchor rod 1 through bolts 5 and nuts 6;

[0032] A fixing clamp 7, which is arranged at the lower section of the fixing steel pipe 4, and an anti-skid foam pad is arranged on the inner side of the fixing clamp 7;

[0033] A horizontal bracket 8, one end of which is fixed to the fixing clamp 7;

[0034] And an adjustable duckbill camera fixing bracket 9, which is arranged on the lower surface of the other end of the horizontal bracket 8.

[0035] In one embodiment of the video monitoring fixture for an underground working surface in a coal mine provided by the utility model, the horizontal bracket 8 also has a fill light installation position 10 .

[0036] In one embodiment of the video monitoring fixing device for underground working surface in a coal mine provided by the utility model, the fixing clamp 7 comprises:

[0037] A fixing portion 71 fixed to the horizontal bracket 8, which has a semicircular snap-in position;

[0038] One end of the semicircular movable portion 72 is hinged to one side edge of the fixed portion 71 , and the other end is fixed to the other side edge of the fixed portion 71 via a buckle.

[0039] In one embodiment of the video monitoring fixing device for an underground working face in a coal mine provided by the utility model, a threaded hole is provided on the fixing steel pipe 4, and the bolt 5 passes through the nut 6 and the threaded hole to fix the fixing steel pipe 4 on the anchor rod 1.

[0040] In one embodiment of the video monitoring fixture for an underground coal mine working surface provided by the utility model,

[0041] The fixed steel pipe 4 is a stainless steel pipe;

[0042] The fixing clamp 7, the horizontal support 8 and the adjustable duckbill camera fixing bracket 9 are all made of stainless steel.

[0043] The utility model utilizes the main function of the anti-drop buckle, which can easily fasten the anchor rod in the anti-drop buckle without falling off. More importantly, it can quickly fasten and release the fastening state of the two objects, and this buckle has an embedded anti-slip foam pad, so that it can remain in a stable state for a long time after fastening. This device can rotate the monitoring camera in any direction, and the monitoring equipment can be moved and the angle adjusted at any time as the extension or recovery progress of the mining working face in the coal mine. The monitoring fixture is made of stainless steel, which is lightweight and easy to install and disassemble. After feedback from the actual use process, the installation hole for the fill light has been added. When the on-site lighting conditions in some areas of the mine are insufficient, the fill light can be hung on this device to meet the monitoring screen requirements. This device facilitates the installation and disassembly, daily maintenance and replacement of video monitoring equipment in coal mines.

The installation and disassembly of the monitoring equipment per shift has been reduced from 3 people per shift to 1 person, and the time has been reduced from 15-17 minutes to 5-8 minutes, which greatly reduces the operation time, safety hazards and labor intensity, and ensures the personal safety of employees at work. The workload of mining workers has been reduced and the efficiency has been improved. When the monitoring equipment is installed, the anchor rod can be easily fixed in the anti-slip buckle. There is no need to worry about not being able to find the wire to fix the camera, and there is no need to spend time tying and untying the wire. The installation and disassembly of the monitoring equipment is more convenient, saving material costs. More importantly, it avoids production safety accidents to a certain extent.

[0045] The repeated binding and unbinding of video surveillance equipment in underground coal mines causes material waste, which to a certain extent avoids the occurrence of injuries such as scratches and eye pokes by wire. The utility model is simple to use, easy to operate, and has a more stable fixing method. It is convenient to install and disassemble the monitoring equipment and adjust the angle appropriately at the specified distance, thereby improving the safety management efficiency.

[0046] The utility model utilizes the commonly used mountain bike stainless steel buckle and a specially matched stainless steel fixing bracket to conveniently fix the underground monitoring equipment on the anchor rod.
