Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] refer to figure 1 , figure 2 , image 3 , the structure of the present invention is, comprises inner frame 1 and outer frame 2, and inner frame 1 and outer frame 2 are frame structure; Outer frame 2 is closed upper end open all around, is mainly used for installing and righting inner frame 1, makes inner Frame 1 can be lifted upwards;

[0046]The top layer and the bottom layer of the inner frame 1 are both fixed structures, and the three sides of the inner frame 1 are closed, and only the side facing the wellhead is an inlet and outlet, and drill pipes can only enter and exit the drill pipe box through the inlet and outlet; the top layer of the inner frame 1 There are multiple layers of drill pipe spacers 7 between the bottom layer and the drill pipe spacers 7 of each layer store the drill pipes in layers to realize the support and...

Abstract

The invention discloses a hydraulic driving lever lifting type automatic drill rod box. The hydraulic driving lever lifting type automatic drill rod box includes an inner frame and an outer frame. Theperiphery of the outer frame is closed, and the upper end is open. The three side surfaces of the inner frame are closed, and only the side surface facing a wellhead is provided with an in-and-out opening. A multi-layer drill rod separating frame is arranged between a top layer and a bottom layer of the inner frame. The outer sides of the two sides of the outer frame are correspondingly providedwith lifting hydraulic cylinders in the longitudinal direction. The top end of a piston rod of the lifting hydraulic cylinder on each side is connected with a hydraulic cylinder guiding assembly. Thehydraulic cylinder guiding assembly on each side is hinged to the short arm ends of two lever lifting arms simultaneously. Four lever lifting arms each are provided with a supporting rotating shaft frame. The long arm ends of the two lever lifting arms on each side are each provided with a sliding wheel. The sliding wheels are in sliding contact with a supporting plate of the lower surface of a lower beam of the inner frame. The hydraulic driving lever lifting type automatic drill rod box is compact in structure, complete in function and high in working efficiency.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and relates to a hydraulically driven lever-lifting automatic drilling rod box. Background technique [0002] The automatic operation of drilling rigs is the main trend in the development of drilling equipment technology at present, and the automatic transmission and processing of pipe strings is an important link to realize the automatic operation of drilling rigs. The existing pipe string automation equipment can realize the pipe string processing from the catwalk to the wellhead of the drilling floor and the management of the second-floor platform. However, the surface pipe string processing and transportation are still mainly operated by personnel and have not yet been automated. for two cases: [0003] Situation 1. During the drilling process of a traditionally configured drilling rig, the drill pipe box is mainly used to store drilling tools (drill pipe, casing, etc.)....
