Abstract
The invention discloses a hydraulic cathead device, comprising a guide frame (1), a mesh enclosure (2), a movable pulley block (3), a steel wire rope group (4), a wobble wheel group (5), a rack (6), and a hydraulic cylinder group (7), wherein the hydraulic cylinder group (7) is arranged at the lower portion of the rack (6), the guide frame (1), the movable pulley block (3), and the wobble wheel group (5) are all arranged at the upper portion of the rack (6), the mesh enclosure (2) is arranged outside the movable pulley block (3), and the steel wire rope group (4) is detachably arranged on the wobble wheel group (5). By using the cathead hook device disclosed herein, safe and easy operation can be realized.
Description
Technical field
The present invention relates to a kind of safety hook, is exactly a kind of hydraulic cathead device specifically.
Background technology
Cat head (Cat Head) is a kind of for the safety hook on the oil field well-digging rig.Be divided into two kinds of pneumatic cat head and hydraulic catworks.It solves, and suspended object does not rotate problem in the lifting process, and at the coupler body opening part self-locking valve with spring is housed, but safe operation.Mainly making the body of bolt with the drop handle coupling end on the coupler body, the body of bolt passes and connects ring body on the drop handle, is assembled into coupler body with gasket ring, bolt and nut of clip, the mutual rotor of drop handle; And fill self-locking valve springy at the coupler body opening part.Adopt cat head drop-hanger can realize easily operation of safety.This this device is widely used in platform and the drilling well at present.
Summary of the invention
The purpose of this invention is to provide a kind of existing middle not enough hydraulic cathead device that overcomes.
A kind of hydraulic cathead device, comprise saddle, guard, movable pulley combination, steel rope combination, wabble wheel combination, frame, hydraulic actuating cylinder combination, described hydraulic actuating cylinder combination is located at the bottom of frame, described saddle, movable pulley combination, wabble wheel combination all are located at the top of frame, described guard is located at the outside of movable pulley combination, and described steel rope combination detouchable is installed in the wabble wheel combination.
Bolt is installed on the frame described in the present invention, and described bolt installation place also is provided with spring shim and nut.
Effect of the present invention and benefit are:
Adopt cat head drop-hanger device of the present invention, can realize easily operation of safety.
