Abstract
The utility model discloses a kind of drill pipe slip supplementary structure, comprise drilling rod, slips, slip spider and the upper plate of parallel interval setting successively, middle plate and base plate, the center of this upper plate, middle plate and base plate is equipped with through hole, drilling rod and slips are placed in this through hole, and the upper end of this slips is fixedly connected with upper plate; Base plate upper side is fixedly installed at least three leads, and middle plate is movably set on this lead, and is arranged with returning spring respectively outward in the part of this lead between upper, middle plate and the part of this lead in this, between base plate; Upper plate upper side being also provided with action bars, bar linkage structure and two semicircle clamping parts, can drivening rod structure making two semicircle clamping part folders state drilling rod and unclamp drilling rod by manipulating this action bars.This drill pipe slip supplementary structure adopts returning spring mechanism to form auxiliary reset mechanism, and not only structure is simple, and easy to use, safety factor is high, and can reduce cost of labor, increases work efficiency.
Description
Technical field
The utility model relates to a kind of drill pipe slip supplementary structure.
Background technology
Drilling slip holds a kind of drilling dynamics slips of tubing string when being and rising detain in going down process for oil, natural gas or geological drilling, at present, existing subject matter is, need during work manually to operate the handling of slips, not only dismounting speed is slow, and easily there is personal injury, damage equipment, reduce operating efficiency.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of drill pipe slip supplementary structure, and not only structure is simple, and easy to use, safety factor is high, and can reduce cost of labor, increases work efficiency.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of drill pipe slip supplementary structure, comprise drilling rod, the slips being located at this drilling rod periphery and the slip spider be located on drill hole inner wall, the outer peripheral face of this slips and slip spider medial surface coordinate, the medial surface of this slips coordinates with drilling rod outer peripheral face and can clamp drilling rod and is fixedly connected with to make the two, described drill pipe slip supplementary structure also comprises the upper plate that parallel interval is successively arranged, middle plate and base plate, this upper plate, the center of middle plate and base plate is equipped with through hole, described drilling rod and slips are placed in this through hole, and the upper end of this slips is fixedly connected with described upper plate, described base plate upper side is fixedly installed at least three leads, described middle plate is movably set on this lead, and is arranged with returning spring respectively outward in the part of this lead between described upper plate and middle plate and the part of this lead in this between plate and base plate, described upper plate upper side is also provided with action bars, bar linkage structure and two semicircle clamping parts, this two semicircular retaining part is outer and be connected with described bar linkage structure one end in described drilling rod, this action bars is connected to the other end of this bar linkage structure, described bar linkage structure can be driven to make two described semicircle clamping parts clamp described drilling rod and unclamp described drilling rod by manipulating this action bars.
As further improvement of the utility model, be fixed with a sleeve in the lead periphery on described base plate, the lower end of described returning spring is placed in this sleeve.
As further improvement of the utility model, described slips is three lobe slips.
The beneficial effects of the utility model are: this drill pipe slip supplementary structure adopts returning spring mechanism to form auxiliary reset mechanism, and not only structure is simple, and easy to use, safety factor is high, and can reduce cost of labor, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is A portion structure for amplifying schematic diagram in Fig. 1.
By reference to the accompanying drawings, make the following instructions:
1---drilling rod 2---slips
3---slip spider 4---upper plate
5---middle plate 6---base plate
7---lead 8---returning spring
9---action bars 10---bar linkage structure
11---semicircle clamping part 12---sleeve
Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But protection domain of the present utility model is not limited to following embodiment, the simple equivalence namely in every case done with the utility model claim and description changes and modifies, and all still belongs within the utility model patent covering scope.
As Fig. 1, shown in 2, a kind of drill pipe slip supplementary structure, comprise drilling rod 1, the slips 2 being located at this drilling rod periphery and the slip spider 3 be located on drill hole inner wall, the outer peripheral face of this slips and slip spider medial surface coordinate, the medial surface of this slips coordinates with drilling rod outer peripheral face and can clamp drilling rod and is fixedly connected with to make the two, described drill pipe slip supplementary structure also comprises the upper plate 4 that parallel interval is successively arranged, middle plate 5 and base plate 6, this upper plate, the center of middle plate and base plate is equipped with through hole, described drilling rod and slips are placed in this through hole, and the upper end of this slips is fixedly connected with described upper plate, described base plate upper side is fixedly installed at least three leads 7, described middle plate is movably set on this lead, and is arranged with returning spring 8 respectively outward in the part of this lead between described upper plate and middle plate and the part of this lead in this between plate and base plate, described upper plate upper side is also provided with action bars 9, bar linkage structure 10 and two semicircle clamping parts 11, this two semicircular retaining part is outer and be connected with described bar linkage structure one end in described drilling rod, this action bars is connected to the other end of this bar linkage structure, described bar linkage structure can be driven to make two described semicircle clamping parts clamp described drilling rod and unclamp described drilling rod by manipulating this action bars.
Preferably, be fixed with a sleeve 12 in the lead periphery on described base plate, the lower end of described returning spring is placed in this sleeve.
Preferably, described slips is three lobe slips.
During trip-out operation, when drilling rod plays proper height stopping, operation action bars drives two semicircle clamping parts clamping drilling rods, now slowly descends kelly bar, due to Action of Gravity Field, drilling rod is by descending, and drive upper plate and middle plate to move to base plate direction, slips is owing to being connected on upper plate simultaneously, though therefore move down before upper plate, in the process moved down, slips, along the slip spider conical surface is descending and final sum slip spider and drilling rod block fixing respectively, now can carry out the actions such as the replacing of drilling rod.Treat that operation completes, external force promotes on drilling rod and moves, and during returning spring promotes respectively, plate and upper plate moves, drive on slips simultaneously and move, slips departs from slip spider and drilling rod, and now manipulation operation bar makes two semicircle clamping parts open, namely unclamp drilling rod, can having free passage of drilling rod be carried out.
