Abstract
The utility model relates to the technical field of drill rig top drive, in particular to a top drive support. Guide wheels are mounted at the back of a support body and are capable of sliding on a top drive guide. A drilling steel wire rope is connected to the upper end of the support body. Two rigid arms are connected to the front of the support body through rotary shafts. The other end of each rigid arm is connected with a top drive through a rotary shaft. One end of a hydraulic cylinder is connected to the lower end of the support body, and the other end of the hydraulic cylinder is connected to one rigid arm. By the top drive support, automation level of a drill rig is increased, the time of connecting a drill stem at a wellhead is saved, and labor intensity is reduced for workers.
Description
Technical field:
The utility model relates to a kind of drill top-drive technical field, and support is driven on particularly a kind of top.
Background technology:
Common drill top-drive links to each other with the hook of rig, is fixed on the top drive guide rail, can not separate with guide rail; The drilling rod interface can only be right against well head; Under when boring, needing miscellaneous equipments such as suspension ring that drilling tool is hung pithead position then could stacks, during trip-out; After drilling rod is dismantled, need other auxiliary equipment that drilling tool is hung the mouse hole position.
The utility model content:
The technical problem that the utility model will solve provides a kind of top and drives support, after the top is driven and is installed on the utility model, can getaway, and arrive the mouse hole stacks automatically, hang pithead position, also can drilling rod be transported to the mouse hole position from well head.The utility model has realized improving the automatization level of rig, the stacks time of practicing thrift well head, reduces working strength of workers.
The technical scheme that the utility model is taked is: support is driven on a kind of top, comprises rack body; Rack body is equipped with directive wheel at the back; Directive wheel can slide on top drive guide rail; The rack body upper end connects drilling line, and the front is connected with two rigid arm through axis of rotation, and the other end of two rigid arm connects the top through axis of rotation and drives; Fluid cylinder one end is connected the rack body lower end, and the other end is connected on the rigid arm.
The beneficial effect of the utility model is: the utility model has been owing to adopted two modes that rigid arm matches with fluid cylinder, thus push up drive be installed on the utility model after, can getaway; Automatically to the mouse hole stacks; Hang pithead position, also can drilling rod be transported to the mouse hole position from well head, improved the automatization level of rig; Practice thrift the stacks time of well head, reduced working strength of workers.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sketch map of the fluid cylinder of the utility model when regaining.
The specific embodiment:
Like Fig. 1, shown in Figure 2, support is driven on a kind of top, comprises rack body 2; Rack body 2 back are equipped with directive wheel, and directive wheel can slide on top drive guide rail 1, can drive the reaction torque power that provides for the top; Rack body 2 upper ends connect drilling line 4, drive the other end that provides pulling force upwards, front to be connected with 3, two rigid arm 3 of two rigid arm through axis of rotation for the top and drive 6 through axis of rotation connection top, have constituted a quadrilateral structure; Fluid cylinder 5 one ends are connected rack body 2 lower ends, and the other end is connected on the rigid arm 3, through the motion of piston, just can realize pushing up and drive 6 the rotation and the compound motion of translation, and when piston stretched out, the top drove 6 over against the mouse hole position, regain the back over against pithead position.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
Claims (1)
