Embodiment 1
[0064] Such as Figures 1 to 5 As shown, the present embodiment provides a mining rig for automatically loading and unloading drill pipes and a water feeder unit, including a water feeder bracket 101-1, a hydraulic winch 102 connected to the water feeder bracket 101-1 to pull the water feeder bracket 101-1 to The water feeder 101 is separated from the drill pipe and the pushing unit 103 between the water feeder bracket 101-1 and the hydraulic winch 102 is used to push the water feeder bracket 101-1 so that the water feeder 101 is connected to the drill pipe; the water feeder bracket 101-1 passes through the moving plate 101-2 is movably installed on the guide rail 101-3 of the water feeder, and the guide rail 101-3 of the water feeder is set on the guide rail bracket 104; the hydraulic winch 102 is installed on the guide rail bracket 104, and the wire rope 102-1 of the hydraulic winch 102 is connected to the water feeder bracket 101-1; the pushing unit 103 is arranged on the g...
Embodiment 2
[0074] Such as Figures 6 to 8 As shown, this embodiment provides a water feeder that can be used in Embodiment 1. The water feeder includes a mandrel 1, a bearing 2 and a bearing sleeve 3 arranged coaxially from the inside to the outside in sequence, and on the side of the mandrel 1 A high-pressure water interface 4 is installed on the wall; it also includes a force transmission hollow shaft 5 with one end closed and the other end open, which is coaxially tightly fitted in the mandrel 1 and can move axially; the high-pressure water interface 4 is sealed and communicated with the force transmission hollow shaft 5 , to pass high-pressure water into the power transmission hollow shaft 5; the closed end of the power transmission hollow shaft 5 is provided with a hydraulic piston, and the open end of the power transmission hollow shaft 5 is flush with the other end of the mandrel 1 and is equipped with a The core rod 10 that moves axially with the force transmission hollow shaft 5...
Embodiment 3
[0081] This embodiment also provides a construction method for the water feeder in the above embodiments, including the following steps:
[0082] Step 1: Push the force transmission hollow shaft to move axially through the hydraulic piston, and push the core rod, annular piston and claws to move axially, so that the second spring and the third spring are compressed, and the moving speed of the core rod is faster than that of the claws The speed makes the wedge-shaped outer wall of the piston block away from the wedge-shaped surface of the claw, the first spring resets, the claw shrinks, and the elastic piece of the claw is inserted into the internal thread of the drill pipe;
[0083] Step 2: Loosen the hydraulic piston again. Under the reset action of the second spring and the third spring, the elastic sheet, annular piston, core rod and force transmission hollow axis move in the direction of the hydraulic piston. During the movement of the elastic sheet, the wedge-shaped outer...
