Description

Technical Field

[0001] The utility model relates to a downhole recorder mounting bracket, belonging to the technical field of downhole operations. Background Art

[0002] At present, coal mining basically relies on underground mining. With the continuous increase in mining depth, the disaster problem caused by rock burst is becoming increasingly prominent. Therefore, when conducting coal mining operations, it is necessary to relieve pressure in the operating area where there is rock burst by drilling. However, whether the pressure relief area can be accurately reached is the key to the success of the operation. When the drilling pressure relief method is used for construction, as the borehole approaches the high stress zone, the frequency and intensity of the occurrence of phenomena such as drilling blowout will increase with the increase of energy accumulated in the coal body. After the borehole is drilled into the coal body, due to the release of the stress of the coal body near the borehole wall, a crushing zone much larger than the borehole diameter is formed around the borehole, and the amount of coal powder will also increase rapidly. Under the action of high stress nearby, coal powder may be ejected rapidly, causing casualties and equipment damage. Therefore, effective protective measures for pressure relief and anti-blowout drilling are of great significance to ensure personnel safety and equipment integrity.

[0003] Therefore, it is very important to monitor the trajectory of the drill rod in real time during the drilling process. During each anti-bumping drilling construction in the well, video archiving management is required for future statistics, research and analysis. However, due to the limitations of the underground environment, video recorders are generally hung on the two-way stretching net of the gang, and the video shooting angle is difficult to control, resulting in poor recorded video effects, and easy shaking or falling due to loose fixation. Utility Model Content

[0004] The utility model aims to solve the technical problems in the prior art of inconvenient video shooting angle adjustment and control and poor video recording effect, and provides a downhole recorder mounting bracket.

[0005] The utility model is realized by the following technical solutions:

[0006] That is, a downhole recorder mounting bracket includes an anchor rod installed in the downhole side wall, a pad and a nut are sleeved on the anchor rod, and the nut presses the pad against the side wall;

[0007] An internal threaded hole is opened at the end of the anchor rod, and a support rod is installed in the internal threaded hole through a thread. A limit ring is fixed at the end of the support rod, and a screw rod is passed through the limit ring. A placement bracket for placing the video recorder is fixed at the top of the screw rod, and a limit nut is also installed on the screw rod, and the limit nut is located above the limit ring.

[0008] The utility model can utilize the supporting anchor rod structure on the underground side wall of the mine. The video recorder is placed in the placement frame. The shooting height of the video recorder is adjusted by adjusting the position of the limit nut. The shooting angle of the video recorder is adjusted by rotating the support rod. The shooting angle and height are easy to adjust and control, and the video recording effect is better.

[0009] Preferably, a locking bolt is installed on the end of the anchor rod, and the end of the locking bolt is screwed into the internal threaded hole. When adjusting the shooting angle of the video recorder, the support rod needs to be rotated and stopped after being rotated to the right position. The locking bolt plays the role of locking the shooting angle, and has good stability.

[0010] Further preferably, the placement rack is a rectangular parallelepiped structure with a hollow interior, and the video recorder is placed in the internal space of the placement rack.

[0011] Further preferably, windows are provided on the front and rear panels of the rectangular structure placement rack.
