Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 As shown, the structure of the modular lifting device of the present invention is composed of an upper lifting module 1, a plurality of intermediate lifting modules 2, and a top drive module 4, which are sequentially connected from top to bottom. The upper lifting module and the middle lifting module 2 are connected and fixed by connecting bolts 3; the middle lifting module 2 and the top drive module 4 are also connected and fixed by using another connecting bolt 3. If it is necessary to upgrade the capacity of the lifting device, add the middle lifting module 2, and install the added middle lifting module 2 between the original middle lifting module 2 and the top drive module 4, and connect and fix it with the connecting bolt 3; according to the upgrade lifting capacity Different, the number of increased intermediate...

Abstract

The invention discloses a modular lifting device which comprises an upper lifting module, a plurality of intermediate lifting modules and a top driving module which are sequentially connected from top to bottom, wherein the upper lifting module and the intermediate lifting modules are connected and fixed through connection bolts; and the intermediate lifting modules and the top driving module are connected and fixed by adopting additional connection bolts. As the modular lifting device provided by the invention adopts a modular structure, the problems of large structure and inconvenience in manufacturing brought about by the existing integral-type lifting device are solved; simultaneously the capability of the lifting device is very convenient to upgrade; lifting devices with different capabilities can be convenient to obtain according to different combinations; and in addition, the number of the intermediate modules can be increased and decreased randomly in the using process to adapt to requirements of working demand.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploration equipment and relates to a modular lifting device. Background technique [0002] The hoisting system of a conventional oil drilling rig is mainly composed of a winch, a crown block, a traveling block, a hook, a faucet, a dead rope fixer, a wire rope, and a rope puller. Moving pulley) to drive the big hook hanging on the lower part of the traveling car, the faucet (or top drive) and the suspended drilling tool to move up and down to complete the lifting function. [0003] The existing conventional drilling rig lifting system is difficult to maintain, low in efficiency, and high in cost. At the same time, the existing lifting device is an integral structure, and the overall shape is bulky, which is inconvenient for processing and manufacturing. Once the structure is determined, subsequent technical upgrades cannot be carried out. Contents of the invention [0004] The purpose of the...
