Abstract
The utility model discloses a drilling well winch driven by a hydraulic motor. Drum shafts at two ends of a roller are respectively provided with a bearing in a sleeving manner. The drum shaft is directly and coaxially connected to an output shaft of the hydraulic motor. The drilling well winch driven by a hydraulic motor is advantageous in that the roller is positioned and supported by the bearings at two ends, and thereby the hydraulic motor does not bear the axial or radial loading; during the drilling process, a single motor, double motors or multiple motors can be chosen to work based on the loading situation; the regulation and control of motor output torque and rotating speed can be achieved by controlling the pressure and flow of a hydraulic system.
Description
Technical field
The utility model belongs to the oil exploration equipment technical field, relates to a kind of well drilling hoist that adopts fluid motor-driven.
Background technology
Winch is one of visual plant of oil-well rig, is mainly used in drilling, control the pressure of the drill, extraction core tube and processing accident etc. in Process of Oil Well Drilling, is undertaking in addition case in, formation testing and is working tasks such as putting frame.Conventional winch all adopts the motor head roll rotation that is used as power, and is furnished with speed-changing mechanism or adopts AC frequency conversion to control, and the subject matter of existence is: complex structure, volume and weight is large, and production and manufacturing cost are high, and trouble point is many, perhaps control system complexity, operation and maintenance requires very high.
The utility model content
The purpose of this utility model is to provide a kind of well drilling hoist that adopts fluid motor-driven, has solved the problem that complex structure, weight are large, cost is high in existing conventional rig.
The technical scheme that the utility model adopts is, a kind of well drilling hoist that adopts fluid motor-driven, the roller sleeve at the cylinder two ends is equipped with bearing, drum shaft directly and the output shaft of HM Hydraulic Motor coaxially connect.
The beneficial effects of the utility model are: utilize the direct head roll of HM Hydraulic Motor, by the rotating speed of controlling HM Hydraulic Motor, with rotation direction, obtain the different rotating speed of cylinder and rotation direction, thereby the lifting that realizes winch with the various functions such as transfer; Simple in structure, compact dimensions, lightweight, maintaining convenient, cost is low, damageable spare parts is few; Simultaneously, with the fluid motor-driven cylinder, saved speed-changing mechanism, improved efficiency, strengthened handlingly, improved the Combination property of winch, be particularly suited for using on platform or drilling ship.
The accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram that the utility model device adopts single motor to drive;
Fig. 2 is the mounting structure schematic diagram that the utility model device adopts double motor to drive;
Fig. 3 is that the utility model device adopts the Thomas to reach the mounting structure schematic diagram of driving.
In figure, 1. HM Hydraulic Motor, 2. cylinder, 3. bearing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model adopts the structure of the well drilling hoist of fluid motor-driven to be: the roller sleeve at cylinder 2 two ends is equipped with bearing 3, realize supporting and location, the drum shaft of cylinder 2 directly coaxially connects with the output shaft of HM Hydraulic Motor 1, realizes the transmission that moment of torsion and rotating speed etc. move.Figure 1 shows that single motor configuration, HM Hydraulic Motor 1 is arranged on left side or the right side of cylinder 2; Figure 2 shows that the double motor structure, two HM Hydraulic Motor 1 are distributed in the both sides of cylinder 2; Fig. 3 reaches structure for the Thomas, and two or more HM Hydraulic Motor 1 are coaxially connected and are combined to form an integral body.Because cylinder 2 is bearing 3 positioning supports by two ends, so HM Hydraulic Motor 1 is not born axially and Radial load substantially.In drilling process, can select single motor operations, double motor or Thomas to reach co-operation according to condition of loading.Realize the regulation and control to motor output torque and rotating speed by the pressure versus flow of controlling hydraulic efficiency pressure system.
Claims (1)
1. a well drilling hoist that adopts fluid motor-driven, it is characterized in that: the roller sleeve at cylinder (2) two ends is equipped with bearing (3), and the output shaft of the drum shaft of cylinder (2) and HM Hydraulic Motor (1) coaxially connects; The HM Hydraulic Motor of every side (1) is two groups and is connected in series.
