Abstract

The utility model provides a water swivel of digging, belongs to mining equipment technical field, can solve current water swivel department and use several postshifts the water spray phenomenon often appear, splash the whole body of workman, and mud is whole to be spouted and is influenced the standardization on the rig in addition, influences the problem of result of use, including hollow water swivel, the one end and the advancing water piping connection of water swivel, the other end is connected with the drilling rod, and the connection end of water swivel and drilling rod is equipped with the sleeve pipe, and the sheathed tube internal diameter matches with the external diameter of water swivel, and the sheathed tube external diameter is bigger than the external diameter of water swivel. The utility model discloses the effectual water spray phenomenon that reduces water pigtail catcher department has reduced the injury to the workman, has improved the result of use.

Description

Drilling water swivel

Technical Field

The utility model belongs to the technical field of mining equipment, concretely relates to beat and bore water pigtail.

Background

In the drilling construction process, one end of the water braid is connected with a water inlet (or air inlet) pipe, and the other end of the water braid is connected with the drill rod, so that flushing fluid outside the hole enters the transition device of the drill rod. When the drill bit works, flushing liquid is introduced to cool the drill bit at the bottom of the hole and remove slag. At present, a drilling machine often sprays water after a drilling water braid connector is used for several shifts, workers are splashed with water, and slurry is completely sprayed onto the drilling machine to influence standardization and use effect.

Disclosure of Invention

The utility model discloses to current water swivel catcher department use several postshifts often appear the water spray phenomenon, to the whole body splash of workman, mud is whole to be spouted and is influenced the standardization on the rig moreover, influences the problem of result of use, provides one kind and drills the water swivel.

The utility model adopts the following technical scheme:

the utility model provides a water swivel of digging, includes hollow water swivel axle, the one end and the water piping connection of water swivel axle, and the other end is connected with the drilling rod, and the link of water swivel axle and drilling rod is equipped with the sleeve pipe, and the sheathed tube internal diameter matches with the external diameter of water swivel axle, and the sheathed tube external diameter is bigger than the external diameter of water swivel axle.

The sleeve is symmetrical along the axis of the swivel.

The length of the sleeve is shorter than that of the connecting end of the water swivel shaft and the drill rod.

The utility model has the advantages as follows:

the utility model discloses on the basis of original water swivel, through utilizing the old and useless take the lead of processing drum type of iron sheet, make it as the sleeve pipe, with the first welding of original water swivel, the effectual water spray phenomenon that reduces water swivel department has reduced the injury to the workman, has improved the result of use. Effectively solves the problems of the drilling machine and the surrounding standardization of the drilling machine.

FIG. 2 is a sectional view taken along line A-A of FIG. 1;

wherein: 1-water swivel; 2-sleeve pipe.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The utility model provides a water swivel of digging, includes hollow water swivel axle 1, the one end and the water piping connection of water swivel axle 1, the other end is connected with the drilling rod, and the link of water swivel axle 1 and drilling rod is equipped with sleeve pipe 2, and the internal diameter of sleeve pipe 2 matches with the external diameter of water swivel axle 1, and the external diameter of sleeve pipe 2 is bigger than the external diameter of water swivel axle 1.

The sleeve 2 is symmetrical along the axis of the swivel 1.

The length of the sleeve 2 is shorter than that of the connecting end of the water swivel shaft 1 and the drill rod.

The utility model discloses an utilize the catcher of old and useless iron sheet processing drum type, make it as the sleeve pipe, with original water swivel head welding, the effectual water spray phenomenon that reduces water swivel catcher department has reduced the injury to the workman, has improved the result of use.
