Description

Technical Field

[0001] This utility model relates to the field of downhole filling technology, specifically to an improved downhole filling pipeline device. Background Technology

[0002] Mining backfill pipes are pipelines specifically designed for backfilling operations in mines. Their main function is to safely and effectively transport specific backfilling materials (such as cement slurry, sand, etc.) to designated goaf areas. Due to the large elevation difference between the filling station and the empty mining area, the transition elbow at the bottom of the vertical pipeline is prone to wear through when transporting high-concentration filling slurry, resulting in slurry leakage and affecting the efficiency of the filling work.

[0005] Preferably, the socket plate is installed at the curved part of the bend in the downhole filling pipe.

[0006] Preferably, the thickness of the socket plate is selected according to the height difference of the underground filling pipeline.

[0007] Preferably, both the socket plate and the socket have four sets of symmetrically distributed bolt holes, and the socket plate and the socket are fixedly connected by the bolt holes and bolts.

[0008] Preferably, a sealing gasket is provided at the connection between the socket plate and the socket.

[0009] Preferably, the ultrasonic thickness gauge is installed at the center of the socket, and the end of the ultrasonic thickness gauge faces the bend of the downhole filling pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a socket plate to withstand the impact force of falling material. Then, through the bolt holes and bolts, a socket equipped with an ultrasonic thickness gauge is fixed to the bend of the underground filling pipeline. The ultrasonic thickness gauge can monitor the inner wall thickness of the socket plate, monitor the wear thickness of the socket plate in real time, and record the wall thickness data in real time through a data terminal. When the wall thickness data is lower than the preset threshold, a spare socket plate is replaced. Attached Figure Description
