Abstract
The invention relates to a hoist. The hoist comprises a machine base, a hydraulic internal contracting brake, a speed reducer and a roller, wherein a supporting lug is fixedly arranged on the machine base, the roller is arranged on the supporting lug through a rotating shaft and connected with the supporting lug rotationally, the machine base is further provided with a variable frequency motor which is sequentially connected with the speed reducer and the rotating shaft, the supporting lug is provided with a moveable limiting stopper, the limiting stopper is connected with the hydraulic internal contracting brake, and the rotating shaft is arranged in the hydraulic internal contracting brake. The hoist is simple in structure and high in practicality.
Description
Technical field
The present invention relates to a kind of winch.
Background technology
Pumping discharge opeing is a procedure the most frequently used in common testing, is the key link that oil-gas exploration and development bears fruit.The hydrocarbon reservoir burial depth of Zhongyuan Oil Field is at 2000～3600m, and there is low hole, hypotonic feature, at present in middle and later periods exploration and development stages, old block ground pressure constantly reduces, exploitation difficulty, deep layer progressive exploratioon and development is increasing the storage Shang Chan important channel, and adopting new formation testing technology and equipment is the objective requirement of oil field fine-grained management.Use on the winch on oil pumper and there is no inhibiting device at present, rope is easy to sideslip, wayward.
Summary of the invention
The present invention is intended to propose a kind of winch that can be spacing.
A kind of winch of the present invention, comprise support, hydraulic contracting, reductor and cylinder, on support, be fixed with journal stirrup, cylinder is arranged on journal stirrup by rotating shaft, and is rotatedly connected in journal stirrup, is also provided with variable-frequency motor on support, variable-frequency motor connects reductor and rotating shaft successively, journal stirrup is provided with movable limiting device, and this limiting device is hydraulic contracting successively, and rotating shaft is arranged on hydraulic contracting inside.
Winch of the present invention, simple in structure, practicality is stronger.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present invention.
1-hydraulic contracting in figure; 2-reductor; 3-cylinder; 4-limiting device; 5-variable-frequency motor; 6-support.
The specific embodiment
A kind of winch of the present invention, comprise support 6, hydraulic contracting 1, reductor 2 and cylinder 3, on support 61, be fixed with journal stirrup, cylinder 3 is arranged on journal stirrup by rotating shaft, and is rotatedly connected in journal stirrup, on support 61, be also provided with variable-frequency motor 5, variable-frequency motor 5 connects reductor 2 and rotating shaft successively, and journal stirrup is provided with movable limiting device 4, and the rope on cylinder 3 is connected on limiting device 4, this limiting device 4 connects hydraulic contracting 1, and rotating shaft is arranged on hydraulic contracting 1 inside.During work, by variable-frequency motor 5, drive cylinder 3 to rotate, when rope reaches after desired location, limiting device 4 is controlled hydraulic contracting 1 and is held rotating shaft tightly, and cylinder 3 stops operating.
