[0008] Meanwhile, by rotating the fixing bolts at the top of both sides of the threaded cylinder frame to press the adjusting rod, the positioning effect of the adjusting rod is achieved, thereby further improving the stability of the support;

[0009] When fixing, the fixing holes on the top surface of the fixing ring are used to fix it to the ground, so as to achieve the effect of supporting and fixing the thermal mining sleeve head body.

[0010] Specifically, a fixing hole is provided on the top surface of the fixing bottom ring corresponding to the side of the supporting threaded cylinder.

[0011] By adopting the above technical solution, the fixing holes on the top surface of the fixing base ring are used to facilitate fixing it to the ground.

[0012] Specifically, the supporting threaded cylinder frame is welded to the top surface of the fixed bottom ring, and the adjusting rod is connected to the top of the supporting threaded cylinder frame through adjusting threads.

[0013] By adopting the above technical solution, the adjusting thread is used to facilitate the rotation and lifting adjustment of the adjusting rod at the top of the supporting threaded cylinder.

[0014] Specifically, the adjusting rods are all connected to the bottom periphery of the thermal recovery casing head body via rotational damping.

[0015] By adopting the above technical solution, rotational damping is used in conjunction with the rotation of the adjusting rod during adjustment.

[0016] Specifically, fixing bolts are inserted through pre-reserved threaded holes at the top positions of the two sides of the supporting threaded cylinder frame corresponding to the adjustment rod positions.
