Detailed Description
The invention will be described in further detail with reference to the following drawings and detailed description:
referring to fig. 1 to 3, the utility model discloses a connect single automatic draw knot device includes handle bar 1, pull rod 2, the vertical setting of axial right circular arc board 3, deflector 4, snap ring 5, right ring 6, spring 7 and circular arc piece 8.
The bottom of the handle rod 1 is hinged with the outer wall of the righting arc plate 3, and the middle of the handle rod 1 is hinged with one end of the pull rod 2. Still connect through a spring 7 between handle bar 1 and the pull rod 2 in order to guarantee that pull rod 2 level sets up, just so can avoid pull rod 2 upset downwards, and then avoid operating personnel to bow to get pull rod 2, reduced intensity of labour.
One end of the pull rod 2 is hinged with the middle of the handle rod 1, the other end of the pull rod is provided with an integrally-made drag hook 21, and the drag hook 21 is used for hooking the kelly bar.
The outer wall of the righting arc plate 3 is hinged with the bottom of the handle rod 1, and the arc inner diameter of the righting arc plate 3 is consistent with the outer diameter of a used drilling tool and a kelly bar protection joint.
Two guide plates 4 are symmetrically formed on two sides of an opening on the upper portion of the righting arc plate 3, wherein the two guide plates 4 are gradually expanded from the righting arc plate 3 to two sides of the righting arc plate, the design is convenient for smoothly guiding a kelly bar to enter the inner side of the righting arc plate 3, and the two guide plates 4 are fixed on the righting arc plate 3 in a welding mode.
Righting 3 inner wall middle parts of circular arc board and going up to be formed with a snap ring 5 along circumference protrusion, snap ring 5 overlap joint and cover on the drilling tool step face of treating to connect, the size of snap ring 5 and the step face phase-match of drilling tool, the width of snap ring 5 equals the width of drilling tool step face, snap ring 5 adopts upper portion welding in order to guarantee the smooth nature of snap ring 5 lower part, thickness is not more than 5mm, 5 length of snap ring are the same with the circumference arc length of righting circular arc board 3, but thickness can not be too thick, prevent to be crowded by kelly bar protection joint and drilling tool. The clamping ring 5 is lapped on the step surface of the drilling tool and can be used as a gravity supporting point; meanwhile, the snap ring 5 can also protect the covered step surface.
