Anti-collision protection device for drilling rig derrick

Abstract

An anti-collision protection device for a derrick of a drilling rig is provided with a support frame, a clamping connection part is installed at the end of the support rod, and several guide parts are installed at one end of the clamping connection part. The supporting frame is composed of several supporting rods; the fastening connection part is composed of two Ω-shaped clips which are correspondingly connected with each other; the guide part is installed on the end of the fastening connection part through the connecting piece. The invention can avoid the impact of welding operation on the strength of the derrick and the damage of the anti-corrosion coating on the surface of the derrick; it is simple to manufacture and easy to use, and solves the anti-collision problem during the installation process of the derrick of the drilling rig; it reduces the difficulty of hoisting construction and overcomes the weather to a certain extent Factors affect offshore and land hoisting locations; at the same time, it reduces hoisting operation risks and safety hazards, and while reducing construction costs, it improves the efficiency of derrick installation and construction.

Description

technical field [0001] The invention relates to a protection device, in particular to an anti-collision protection device for a derrick of a drilling rig during hoisting construction at sea or on land, and belongs to the field of offshore oil engineering. Background technique [0002] The derrick of offshore oil drilling rig is generally a steel structure composed of section steel, and the steel structure of the derrick itself is fastened by bolts. During the hoisting process, there are generally the characteristics of complex operating environment, high positioning accuracy, many drilling platform equipment and small operating space. At present, the anti-collision measures of drilling rig derrick mainly adopt on-site manpower traction rope control or weld temporary auxiliary structures on the derrick to form protection for the derrick. Due to the human traction at the hoisting site is easy to be controlled by the field operation range, the risk is high and there are many u...
