Problems solved by technology

However, the current power catwalk system mainly has the following deficiencies: the type and quantity of small and medium-sized oil drilling rigs with low drilling floor heights such as vehicle-mounted drilling rigs and hydraulic drilling rigs are relatively small; the applicable drilling floor height is relatively fixed, and the adjustment range is limited; In the process of moving the drilling tools from the drill rack to the main body of the catwalk, human power is still required, and no complete automation has been realized; most of the hoisting methods are wire rope traction, and the flexible hoisting method of the wire rope has low transmission accuracy. There will be shaking during the process, and the stability is poor

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and example the present invention will be further described:

[0016] Such as figure 1 , figure 2 and image 3 As shown, the lift-type hydraulic power catwalk system of the present invention includes five mechanisms of a drilling tool rack turning out mechanism, a turning arm mechanism, a turning plate mechanism, a lifting mechanism, and a pulley mechanism.

[0017] The specific structure of the drill rack pull-out mechanism is that the pull-out hydraulic cylinder 10 is hinged with a fixed point on the bottom plate 17, the other end is hinged with one end of the pull-out plate 18, and the other end of the pull-out plate 18 is hinged with the support frame 9. The support frame 9 is fixed on the base plate 17 .

[0018] The specific structure of the turning arm mechanism is that the lifting plate 26 is fixed on one end of the turning arm 12, in order to prevent the drilling tool 8 coming from the drilling tool frame 16 fr...

Abstract

The invention belongs to the technical field of petroleum machinery and particularly provides a lifting type hydraulic power catwalk system designed for transporting drilling tools automatically between a drilling tool rack and a drilling floor. The lifting type hydraulic power catwalk system mainly comprises a drilling tool rack turn-out mechanism, a turn-over arm mechanism, a turn plate mechanism, a lifting mechanism and a tackle mechanism, wherein the drilling tool rack turn-out mechanism transports the drilling tools between the drilling tool rack and a main catwalk body by the aid of lifting of hydraulic cylinders; the turn-over arm mechanism transports the drilling tools from turn-over arms to conveying arms or returns the drilling tools; the turn plate mechanism cooperates with the turn-over arm mechanism to transport single drilling tool from the turn-over arms to the conveying arms or return the drilling tool; the lifting mechanism lifts the conveying arms for conveying the drilling tools to a certain height; the tackle mechanism pushes the drilling tools out for a certain distance along the conveying arms. The lifting type hydraulic power catwalk system has the advantages of high degree of automation, high applicability and stability, simple structure, stability and reliability, and is particularly suitable for operation of medium-small sized drilling rigs with lower drilling floors.

Description

technical field [0001] The patent of the invention belongs to the technical field of petroleum machinery, specifically a lifting hydraulic power catwalk system designed to realize the automatic movement of drilling tools between the drilling tool frame and the drilling floor. Background technique [0002] The traditional drilling tool operation method mainly relies on manpower. This operation method has disadvantages such as poor safety, high labor intensity, and low work efficiency, which greatly limits the development of automatic drilling systems. In order to change the traditional operation mode of drilling tools, since the 1940s, the research and production application of hydraulic power catwalk technology have been carried out abroad. Domestic research on hydraulic power catwalk technology started relatively late. After development in recent years, hydraulic power catwalk systems supporting some drilling rigs have appeared in China. However, the current power catwalk ...
