Abstract
A catch-type broken rod fishing machine tool mainly solves the problem that a broken rod is probably kept underground and cannot be taken out when an existing broken rod fishing device fishes a drill rod. The catch-type broken rod fishing machine tool is characterized in that a pin tap (3) is connected with the left end of the drill rod (4), a connecting piece (2) is fixed on the outer wall of the pin tap (3), an umbrella-shaped catcher (1) is arranged on the left side of the pin tap (3), the left end of the umbrella catcher (1) is horn-mouth-shaped, and the right end of the umbrella-shaped catcher (1) is connected with the connecting piece (2) through a bolt. The situation that the broken rod is kept underground is not prone to happening during the fishing process of the catch-type broken rod fishing machine tool, and working is reliable.
Description
Technical field
The utility model relates to field, a kind of oil field, and the disconnected bar of a kind of catching type is salvaged facility specifically.
Background technology
In the horizontal directional drilling construction, drilling rod (tool) fracture is one of common construction accident.Drilling rod (tool) returns at guiding, reaming and pipeline and drags in the process once fracture, will cause engineering and have a strong impact on, the main remedial measure of taking at present is to utilize respectively mechanical device to return in unearthed point with a both sides of burying to drag, and the drilling rod (tool) of fracture is hauled out ground from boring.And in returning the process of dragging, disconnected bar may be trapped in underground can't the taking-up, will cause so whole creeping into unsuccessfully, must select the place else again to construct, and this not only causes loss economically, and affects the duration.
Summary of the invention
When salvaging drilling rod, may make disconnected bar be trapped in the underground deficiency that can't take out in order to overcome existing disconnected bar fishing device, the utility model provides the disconnected bar of a kind of catching type to salvage facility, the disconnected bar of this catching type is salvaged facility difficult bar that occurs to break in the salvaging process and is detained underground situation, reliable operation.
The technical solution of the utility model is: the disconnected bar of a kind of catching type is salvaged facility, comprise drilling rod, the right-hand member of drilling rod connects rig, described drilling rod left end is connected with die nipple, be fixed with brace on the outer wall of die nipple, the left side of die nipple is provided with the umbrella shape catcher, and the left end of described umbrella shape catcher is toroidal, and umbrella shape catcher right-hand member and brace are bolted.
Described die nipple is replaced by female coupling tap.
The utlity model has following beneficial effect: owing to take such scheme, the left end of drilling rod connects the umbrella shape catcher, the end of umbrella shape catcher is loudspeaker device shape, maximum outside diameter is slightly less than hole, can look for voluntarily and align for the residual fracture drilling rod that comes off at the bottom of the hole, connect by die nipple (or female coupling tap) bar that will break, returned by rig and drag, the bar that will break is salvaged out from hole.This is salvaged facility and salvages disconnected bar conveniently, reliably, is difficult for occuring the underground situation of disconnected bar delay, has improved operating efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-umbrella shape catcher among the figure, 2-die nipple, 3-brace, 4-drilling rod.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the disconnected bar of a kind of catching type is salvaged facility, comprise drilling rod 4, the right-hand member of drilling rod 4 connects rig, and described drilling rod 4 left ends are connected with die nipple 2, be fixed with brace 3 on the outer wall of die nipple 2, the left side of die nipple 2 is provided with umbrella shape catcher 1, and the left end of described umbrella shape catcher 1 is toroidal, and its section edges is hyperbola, maximum outside diameter is slightly less than hole, and umbrella shape catcher 1 right-hand member and brace 3 are bolted.Wherein die nipple 2 can be replaced by female coupling tap, and other structure is identical.
In when, in the horizontal directional drilling work progress drill rod breaking accident occuring, for being detained the situation of underground disconnected pole-footing according to drill rod breaking, select and die nipple 2(or female coupling tap that the used drilling rod model of horizontal directional drill is complementary) be connected die nipple 2(or female coupling tap with umbrella shape catcher 1) other end passes through drilling rod 4 and links to each other with horizontal directional drilling machine.Rig is salvaged facility from burying a little or unearthed point with the disconnected bar of catching type, deliver to the position of drill rod breaking along the hole that has been drilled to, umbrella shape catcher 1 bar that will break is picked up, rig drives die nipple 2(or female coupling tap) to disconnected bar tapping, when die nipple 2(or female coupling tap) with disconnected bar fully in conjunction with after, rig returns and drags operation, and the bar that will break is hauled out from the underground opening, finishes whole fishings.The disconnected bar of this catching type is salvaged facility through the multinomial engineering test that passes through, and has captured the horizontal directional drilling construction and has interrupted the technical barrier that bar is salvaged, for the horizontal directional drilling smooth construction provides guarantee.
Claims (2)
1. the disconnected bar of catching type is salvaged facility, comprise drilling rod (4), the right-hand member of drilling rod (4) connects rig, it is characterized in that: described drilling rod (4) left end is connected with die nipple (2), be fixed with brace (3) on the outer wall of die nipple (2), the left side of die nipple (2) is provided with umbrella shape catcher (1), and the left end of described umbrella shape catcher (1) is toroidal, and umbrella shape catcher (1) right-hand member and brace (3) are bolted.
2. the disconnected bar of catching type according to claim 1 is salvaged facility, and it is characterized in that: described die nipple (2) is replaced by female coupling tap.
