AI Technical Summary

Technical Problem

The existing drilling rig slewing mechanism has problems such as excessive mechanism, poor resistance to drill rod reaction performance, poor stability and construction instability, which is difficult to meet the construction requirements of different heights and angles.

Method used

The four-linked rod lifting and all-round rotation device is adopted, including the first flip beam, the upper link, the front link, the rear link, the rotary seat, the first flip beam oil cylinder and the lifting cylinder. The plane four-linking rod mechanism is formed by hinging, and the role of the flip beam oil cylinder and the lifting cylinder is used to achieve multi-directional construction in vertical and horizontal directions.

Benefits of technology

It improves the stability and construction flexibility of the drilling rig, makes it easy to move, meets construction requirements of different heights and angles, and reduces maintenance costs and construction risks.

Abstract

The present invention provides a four-link lifting omnidirectional rotating device, comprising: a moving beam, a moving oil cylinder, a second flip beam, two flip beam oil cylinders, a first flip beam, an upper connecting rod, a front connecting rod, a rear connecting rod, a swivel seat, a flip beam oil cylinder, a lifting oil cylinder, a swivel support bearing, a working platform, a locking oil cylinder and a locking pressure block. The first flip beam is hinged to the upper connecting rod, one end of a flip beam oil cylinder is hinged to the first flip beam, and the other end is hinged to the upper connecting rod to form a flip mechanism. Under the action of the two flip beam oil cylinders and the one flip beam oil cylinder, construction in the vertical direction of 90° to +90° is achieved. The upper connecting rod, the front connecting rod, the rear connecting rod and the swivel seat are hinged to form a planar four-link mechanism. Under the action of the lifting oil cylinder and the flip beam oil cylinder, the four-link mechanism is lifted and lowered in a straight line, resisting the horizontal component force, and improving the stability of the mechanism. The present invention makes the drilling rig easy to move and can meet the purpose of construction requirements of different heights and different angles.
