Embodiment 1

[0045] Such as Figures 1 to 3As shown, this embodiment provides a claw-type water feeder, which includes a mandrel 1, a bearing 2 and a bearing sleeve 3 arranged coaxially from the inside to the outside in sequence, and a high-pressure water interface is installed on the side wall of the mandrel 1 4; It also includes a force transmission hollow shaft 5 coaxially tightly fitted in the mandrel 1 and capable of moving axially, with one end closed and the other end open; the high-pressure water interface 4 is sealed and connected to the force transmission hollow shaft 5, which is used for the force transmission hollow shaft 5. The shaft 5 is connected with high-pressure water; the closed end of the power transmission hollow shaft 5 is provided with a rotating handle 6 that can push the power transmission hollow shaft 5 through rotation, and the open end of the power transmission hollow shaft 5 is provided with transmission shafts in sequence along the axial direction. The force h...

Embodiment 2

[0054] This embodiment also provides a construction method of a claw-type water feeder, comprising the following steps:

[0055] Step 1: Install and turn the rotary handle so that the positioning balls snap into the ball grooves, and the rotary handle is perpendicular to the force transmission hollow shaft;

[0056] Step 2: The trapezoidal end of the rotating handle pushes the force-transmitting hollow to move axially, and the force-transmitting hollow shaft pushes the annular piston to move axially, and shrinks the spring located between the annular piston and the piston cylinder, and the annular piston pushes the jaws to move axially. Move, the ball located between the wedge-shaped surface of the claw and the wedge-shaped inner wall presses the elastic claw tightly so that the elastic claw fastens the drill pipe coaxially sleeved in the claw;

[0057] Step 3: Introduce high-pressure water into the high-pressure water interface, and the high-pressure water enters the annular ...

Abstract

The invention discloses a clamping claw type water supply device and a construction method thereof. The clamping claw type water supply device comprises a mandrel, bearings and a bearing sleeve whichare coaxially arranged in a distributed mode in sequence from inside to outside, and a high pressure water connector is installed on the side wall of the mandrel. The clamping claw type water supply device further comprises a force transmission hollow shaft which is coaxially and tightly installed in the mandrel in a sleeved mode, and the high pressure water connector is in communication with thetransmission force hollow shaft in a sealing mode. A rotating handle is arranged at the closed end of the force transmission hollow shaft, and an annular piston and a clamping claw are sequentially arranged at the open end of the force transmission hollow shaft in the axial direction. The clamping claw comprises a cylindrical part and elastic claw pieces sequentially arranged in a distributed modeat intervals in the circumferential direction of the cylindrical part, and claw piece wedge-shaped surfaces are arranged on the end parts of the elastic claw pieces. A clamping claw sleeve coaxiallysleeves the outer wall of the clamping claw, and one end of the clamping claw sleeve is fixedly connected to the end part of the bearing sleeve through a piston cylinder barrel. A wedge-shaped inner wall matched with the claw piece wedge-shaped surfaces is arranged on the inner wall of the other end of the clamping claw sleeve, and balls are disposed between the claw piece wedge-shaped surfaces and the wedge-shaped inner wall. According to the clamping claw type water supply device and the construction method thereof, the instantaneous disassembly and assembly of the water supply device and adrill pipe can be realized, high pressure resistance, simple operation and high reliability are achieved, and the drilling efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of underground water feeders for coal mines, and in particular relates to a claw-type water feeder and a construction method thereof. Background technique [0002] In the process of underground drilling in coal mines, a water feeder is required to deliver high-pressure flushing medium to the inside of the drill pipe to discharge slag or drive a power motor at the bottom of the hole. In the prior art, the water feeder cannot be quickly connected to the drill pipe, and the drill pipe needs to be installed and removed frequently through the water feeder to complete the drilling construction and deal with stuck drill accidents. At present, the loading and unloading of the water feeder needs to be manually operated by a special person, and the labor intensity of the workers is high and the efficiency is low. Contents of the invention [0003] Aiming at the defects and deficiencies in the prior art, the present...
