Abstract
The utility model relates to a B type clamp for an automatic drilling machine, in particular to a hydraulic driving device of a well drilling clamp. The device comprises a hydraulic station and the B type clamp. One ends of an oil return pipe and an oil feeding pipe are connected with the hydraulic station, the other ends of the oil return pipe are connected with a hydraulic cylinder, one end of the hydraulic cylinder is installed on the lateral face of a well frame of the drilling machine through a fixed support seat, and the other end of the hydraulic cylinder is connected with the position of the B type clamp requiring pulling force through a lug plate. The hydraulic driving device can conduct large-angle rotation by adopting hydraulic driving, removes steel wire rope connection, is small in noise and accurate and stable in control and improves device running safety. The hydraulic driving device overcomes the shortcoming of personal accidents caused by the fact the existing B type clamp is powered by the steel wire rope which is easy to break.
Description
Technical field:
The utility model relates to the Type B pincers that a kind of automated drilling rig is used, particularly a kind of drilling well pincers fluid pressure drive device.
Background technology:
In existing oil-well rig, connect by screw thread between drilling rod.The connection of screw thread needs the rotation of Type B pincers to complete.Existing Type B pincers are all to provide power by the hydraulic catwork of installing on the cat shaft of winch or drilling floor surface by wire rope,, very easily skid due to wire rope or rupture and cause the personal safety accident when unloading the drilling rod button upper.
The utility model content:
The technical problems to be solved in the utility model is to provide a kind of drilling well and clamps fluid pressure drive device, and this device adopts hydraulic-driven can carry out the rotation of wide-angle degree, cancels wire rope and connects, and noise is little, and precise control, steady improves the device Operation safety.Having overcome existing Type B pincers all provides power by wire rope, and wire cable rupture easily causes the deficiency of personal safety accident.
Technical solution adopted in the utility model is: a kind of drilling well pincers fluid pressure drive device comprises Hydraulic Station and Type B pincers; Oil return pipe is connected end and is connected Hydraulic Station with oil inlet pipe, the other end connects fluid cylinder, and fluid cylinder one end is arranged on the side of drilling derrick by fixed bearing, and the other end is connected to by otic placode the position that the Type B pincers need pulling force.
The beneficial effects of the utility model are: the utility model has been owing to having adopted fluid cylinder, thereby has and can carry out the function of wide-angle degree rotation by hydraulic-driven, cancels wire rope and connects, and noise is little, and precise control, steadily improves the device Operation safety.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of drilling well pincers fluid pressure drive device comprises Hydraulic Station 1 and Type B pincers 6; Oil return pipe 2 is connected an end and is connected Hydraulic Station 1 with oil inlet pipe, the other end connects fluid cylinder 5, and fluid cylinder 5 one ends are arranged on the side of drilling derrick by fixed bearing 4, and the other end is connected to by otic placode the position that Type B pincers 6 need pulling force.By the power that Hydraulic Station 1 provides, fluid cylinder 5 can stretch, thereby completes the spinning movement of Type B pincers 6, completes the connection work of whole drilling rod button.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
