1, with dynamic rathole device, compare, it has simple in structure, easy to maintenance, cheap advantage; Be embodied in:
1) adopt slips location drilling rod, centering righting effect is better, more is conducive to the drilling rod make-up and connects;
2) adopt the slips detent mechanism, guaranteeing that the rat hole cylinder has under sufficient length, drilling rod is transferred while entering rat hole, without damping, buffering mechanism;
3) adopt the slips detent mechanism, can transfer while entering rat hole to correct position and block drilling rod at drilling rod, when this position, tool joint top is to the distance of drilling floor surface, meet the requirement that iron driller or liquid gas tong carry out spinner and link closely and operate, without move up and down drilling rod as dynamic rathole, regulate the drilling rod position.
2, contrast conventional rat hole structure, its beneficial effect is embodied in:
1) adopt slips location drilling rod, centering righting effect is better, more is conducive to the drilling rod make-up and connects;
2) adopt the slips detent mechanism, guaranteeing that the rat hole cylinder has under sufficient length, drilling rod is transferred while entering rat hole, without damping, buffering mechanism;
3) adopt the slips detent mechanism, in the situation that installing space is enough, its applicable run of steel is unrestricted.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
embodiment 1
A kind of slip-type rat hole, as shown in Figure 2, comprise: rat-hole scabbard 1, support plate 2, gusset 3, liner 4, pedestal 5, described rat-hole scabbard 1 is fixed in the hole on support plate 2 by the mode of welding, rat-hole scabbard 1 is positioned at support plate 2 belows, described pedestal 5 is fixed on the upper surface of support plate 2 by the mode of welding equally, and welding gusset 3 is strengthened between support plate 2 and pedestal 5.As shown in Figure 3, be processed with the second location and installation conical surface 51 in described pedestal 5, the second location and installation conical surface 51 is positioned on the step surface of described pedestal 5 interior step, and the diameter of its conical surface becomes greatly gradually from top to bottom, and described liner 4 is arranged on pedestal 5 inside.As shown in Figure 4, described liner 4 inside are processed with the conical surface, the tapering of the conical surface meets the petroleum industry standard, can be used in conjunction with the slips with normal cone, described liner 4 is processed with the first location and installation conical surface 42, with the second location and installation conical surface 51 on pedestal 5, coordinate, so that location better to be installed.
The slip-type rat hole is assembled as shown in Figure 2, and as shown in Figure 1, support plate 2 is fixed on mounting rail by welding or bolted mode.Generally, the extreme higher position of rat-hole scabbard 1 is a little less than drilling floor surface.
When being made up a joint operation, by manipulator, first drilling rod put into to the slip-type rat hole, and put into slips while transferring to correct position and block drilling rod, when this position, tool joint top is to the distance of drilling floor surface, meet the requirement that iron driller or liquid gas tong carry out spinner and link closely and operate, utilize manipulator that second drilling rod moved to the rat hole top, and coordinate iron driller or liquid gas tong (not expressing in figure) to complete spinner and the operation of linking closely, first drilling rod and second drilling rod are connected into to double joint.Now, if be equipped with two rat holes, the 3rd drilling rod can be put into to second rat hole by manipulator, and put into slips at correct position and block, the double joint that the recycling manipulator will connect is before mentioned, and move to second rat hole top, and coordinate iron driller or liquid gas tong (not expressing in figure) to complete spinner and the operation of linking closely, double joint and the 3rd drilling rod are connected into to thribble.If only configured single rat hole, robotic arm holds the double joint connected, take out slips, the recycling manipulator is transferred double joint, until correct position is put into slips and blocked double joint, when this position, double joint joint top, to the distance of drilling floor surface, meets the requirement that iron driller or liquid gas tong carry out spinner and link closely and operate, and then the 3rd drilling rod and double joint is connected into to thribble.In this operation, because the marine drilling platform drilling floor surface has enough height, can the requirement of double joint being put into to rat hole will be met.
While unloading thribble, if two rat hole configurations, operate relatively simply, can be undertaken by aforementioned reverse procedure, if the configuration of single rat hole, after two of bottoms in thribble drilling rod need to being put into to rat hole and blocking, the 3rd drilling rod of thribble topmost first dismantled, and sent back to the pipe racking district with manipulator, more remaining double joint in rat hole is mentioned, and dismantle, put back to successively the drilling rod district.
Simultaneously, for reducing labor strength, above-mentioned slips can adopt power plunged-in type slips to substitute.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
