Embodiment Construction

[0051] figure 1 , figure 2 It shows a telescopic overall hoisting type derrick device, which includes a derrick support platform 7 detachably fixedly connected with the drilling platform, a derrick body arranged on the support platform 7, a pipe row machine platform 8, a second floor platform 9, a sleeve The pipe platform 10, crown block 1 and root service platform 22, the main drawworks 14 are detachably fixedly installed on the lower part of the derrick support platform 7, and the base of the main winch and the derrick support platform 7 are hinged with small beams. The main drawworks 14 can be hoisted together with the derrick, and as the crane is overweight, the main drawworks 14 can also be separated from the derrick support platform 7 for separate hoisting. The derrick body is divided into an upper section 2 of the derrick body and a lower section 3 of the derrick body; one side of the lower end of the lower section 3 of the derrick body is hinged to one side of the up...

Abstract

The invention discloses a telescopic overall hoisting derrick device and a hoisting method thereof. The derrick body is divided into a derrick body upper section and a derrick body lower section, wherein the derrick body upper section is arranged in the derrick body lower section; a roller device is arranged between the derrick body upper section and the derrick body lower section; when the derrick body upper section completely retracts in the lower section and is positioned at a horizontal position, the overall gravity center of the derrick device is positioned at a central position of a derrick supporting table; a telescopic derrick driving device is arranged between the derrick body upper section and the derrick body lower section; and a derrick hoisting hydraulic cylinder is arranged on the derrick supporting table and drives the derrick body lower section to change from a horizontal state to a vertical state. The hoisting method comprises a mounting method, a detaching method and a hoisting method, wherein the mounting method is a sectioned hoisting mounting method. The derrick device is unique and ingenious in design, overall in hoisting, time-saving and labor-saving, and great detachment is not required, so that the using cost and the maintenance cost are greatly saved, and the using and mounting efficiency and the safety are improved.

Description

technical field [0001] The invention relates to an oil well equipment and an equipment hoisting method, in particular to a derrick device and a hoisting method thereof. Background technique [0002] At present, the derrick movement of the fixed offshore oil drilling platform mainly adopts the method of disassembling the derrick and equipment on the platform, hoisting them in sections to the barge and transporting them to the destination, and then hoisting them in sections from the barge to the platform. During the hoisting process, components are easily damaged by collisions. Some components and equipment, such as top drive guide rails, need to be re-adjusted, which is time-consuming and laborious, and re-assembly will bring various safety hazards. We urgently need a kind of overall hoisting, without a lot of repeated disassembly and assembly, time-saving, labor-saving, efficient, and able to adapt to the derrick of the offshore oil drilling platform. Contents of the inven...
