Embodiment Construction

[0019] Attached below figure 1 , 2 , 3, 4, 5, 6, 7, 8 describe an embodiment of the present invention.

[0020] A mobile device for an oil drilling rig, consisting of a moving guide rail 1, a push-pull cylinder 2 and a hydraulic system 3; Each guide rail unit 21 is composed of an outer guide rail 7 and an inner guide rail 8 , and the outer guide rail 7 and the inner guide rail 8 are connected and fixed together by a connector 9 , and two rows of step holes 5 are evenly distributed on the inner guide rail 8 . Drilling rig 4 is located on the four guide rails of wellhead 20 left and right sides. The two oil cylinder supports 6 are respectively inserted into the two rows of step holes 5 on the two inner guide rails 8 . The oil cylinder support 6 is composed of a plate-shaped body 9 and a block 10. Four blocks 10 are symmetrically inserted and welded vertically at the four corners of the plate-shaped body 9, and the lower parts of the four blocks 10 are inserted into the step h...

Abstract

The invention relates to a moving device for a petroleum drilling machine. The device is provided with moving guide rails (1), push-pull oil cylinders (2) and a hydraulic system (3), wherein the moving guide rails (1) are formed by mutually connecting equal-length guide rail units (21); a drilling machine (4) is positioned on the moving guide rails (1); stepping holes (5) are uniformly distributed on the guide rails (1); oil cylinder supports (6) are inserted into the stepping holes (5); the cylinder ends of the push-pull oil cylinders (2) are hinged with the oil cylinder supports (6), and the piston ends of the push-pull oil cylinders (2) are hinged with the base of the drilling machine (4); and the push-pull oil cylinders (2) are connected with the hydraulic system (3). In the device, the drilling machine is directly positioned on the moving guide rails, and the drilling machine does not need lifting when moved. The device has a simple structure, is convenient to operate in site, has a safe and fast whole moving process and completely meets the requirements of the whole moving of oilfield drilling machines in short distances.

Description

technical field [0001] The invention belongs to the technical field of oil drilling rigs, and in particular relates to a mobile device for oil drilling rigs. Background technique [0002] The existing drilling rig moving device uses the jacking system to lift the drilling rig, then drags the drilling rig translation guide rail into the base of the drilling rig, and then uses the jacking system to make the drilling rig seat on the translation guide rail, and then uses the hydraulic system to translate the drilling rig along the guide rail to the bottom. A wellhead, and finally use the jacking system to jack up the drilling rig and remove the translation guide rail of the drilling rig, so that the drilling rig can be seated at the wellhead. The device is not only complex in structure and inconvenient to operate on site, but also has potential safety hazards and takes a long time during the transfer process, which cannot meet the needs of safe, fast and convenient short-distanc...
