Example (b):

as shown in figures 1 to 4:

the utility model provides a device for removing an inner welding ring of an oil drill rod, which comprises a supporting base plate 1; a group of lower fixed seats 2 are fixedly arranged on the left side of the top of the supporting bottom plate 1; the top of the lower fixed seat 2 and the bottom of the upper fixed seat 3 are both provided with a group of arc-shaped grooves, the diameter of the arc-shaped groove on the left side is smaller than that of the arc-shaped groove on the right side, and the diameter of the joint part of the oil drill rod is large, so the oil drill rod can be limited in the groove and cannot slide outwards; a group of supporting frames 4 are fixedly arranged on the front side and the rear side of the lower fixed seat 2;

the top of the support frame 4 is a horizontal plate, the bottom of the support frame 4 is two vertical round rods, and the round rods at the bottoms of the two groups of support frames 4 respectively penetrate through round holes at the front side and the rear side of the upper fixing seat 3, so that the upper fixing seat 3 can slide up and down on the outer side of the support frame 4, and the petroleum drill rod can be clamped and loosened; an upper fixed seat 3 is slidably arranged between the two groups of supporting frames 4; two springs 5 are arranged on the outer sides of the two groups of supporting frames 4; a hydraulic cylinder 6 is fixedly arranged on the right side of the top of the supporting bottom plate 1 through a fixing frame; the left end of the hydraulic cylinder 6 is fixedly connected with a punch 7; the front side and the rear side of the left end of the inner cylinder body of the hydraulic cylinder 6 are also connected with a group of pressure arms 8.

Wherein, spring 5 sets up the round bar outside in 4 bottoms of support frame respectively, and 5 bottoms of spring and the 1 top face contaction of supporting baseplate, top and 3 bottom face contactions of last fixing base, consequently spring 5 can promote when no external force is applyed fixing base 3 and remove the top to can make fixing base 3 and lower fixing base 2 part, be convenient for place and take out oil drill pipe.

Wherein, the pressure arm 8 comprises two horizontal plates and an hang plate, the horizontal plate is located the left and right sides respectively, the hang plate is located the centre, and when last fixing base 3 rose to the highest time, the left horizontal plate of pressure arm 8 hugs closely in the top front and back side of last fixing base 3, when last fixing base 3 hugs closely with lower fixing base 2, the horizontal plate on pressure arm 8 right side hugs closely in the top front and back side of last fixing base 3, consequently just can be in advance through pressing arm 8 to go up fixing base 3 and push down when carrying out die-cut removal to the internal welding ring, make and go up fixing base 3 and hug closely with oil drill rod clamp fastening with lower fixing base 2, need not to press from both sides oil drill rod tightly alone fixedly, it is more convenient to operate.

Wherein, when pneumatic cylinder 6 drove jumper bar 7 and moved rightmost side, the distance on jumper bar 7 leftmost side and 2 right sides of lower fixing base is greater than the horizontal length of the middle hang plate of last fixing base 3, and the left side of hang plate and the contact of the front and back side top face right side of last fixing base 3 this moment, so last fixing base 3 move down to hug closely with 2 tops of lower fixing base when the left end of jumper bar 7 still can be located the oil drill pipe outside, consequently also can guarantee to press from both sides the oil drill pipe effectively tightly.

The specific use mode and function of the embodiment are as follows:

in the utility model, when the device is required to remove the inner welding ring of the oil drill rod, the hydraulic cylinder 6 is controlled to contract to drive the punch 7 and the pressure arm 8 to move rightwards, when the pressure arm 8 moves to the rightmost side, the spring 5 outside the round rod at the bottom of the support frame 4 pushes the upper fixing seat 3 to slide to the uppermost side, then the joint of the oil drill rod is plugged into the large-diameter arc-shaped groove at the right side of the top of the lower fixing seat 2, because the joint part of the oil drill rod has a large diameter, the oil drill rod is limited in the groove and cannot slide outwards, then the hydraulic cylinder 6 is controlled to extend to push the punch 7 and the pressure arm 8 to move leftwards, the inclined plate in the middle of the pressure arm 8 is contacted with the top surfaces at the front side and the rear side of the upper fixing seat 3 and continuously moves leftwards in the process, so that the upper fixing seat 3 can be gradually pressed downwards until the horizontal plate at the right side of the pressure arm 8 is contacted with the top surfaces at the front side and the rear side of the upper fixing seat 3, at this moment, the bottom of the upper fixing seat 3 can be tightly attached to the top of the lower fixing seat 2, so that the upper fixing seat 3 and the lower fixing seat 2 can firmly clamp and fix the oil drill rod inside, the left end of the punch rod 7 in the process still can be located outside the oil drill rod, and therefore effective clamping of the oil drill rod can be guaranteed, and finally the hydraulic cylinder 6 continues to push the punch rod 7 to move leftwards, at this moment, the left end of the punch rod 7 can be embedded into the oil drill rod to punch down an inner welding ring, the hydraulic cylinder 6 is controlled to shrink again after punching is completed, the punch rod 7 is pulled outwards, and the oil drill rod is loosened and taken out.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the utility model in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the utility model and the practical application, and to enable others of ordinary skill in the art to understand the utility model for various embodiments with various modifications as are suited to the particular use contemplated.
