Problems solved by technology

At present, the finger beams of conventional second-floor platforms are generally equipped with hanging chains or pallets to limit the position of the drill string. It is necessary for the derrick worker to cross the 26-meter-high gap between the monkey platform and the finger beam to disassemble and assemble the chains or reverse the clamping. board, this kind of operation is labor-intensive and high-risk

Embodiment Construction

[0016] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0017] The traditional finger beam device blocks a single working tube through a single opening and closing rod, and fixes the working tube in a limited position. However, due to the strong wind and waves on the offshore platform, the working tube may be affected by the wind and the opening and closing rod will be hit and opened (that is, the traditional The opening and closing rod cannot form a reliable protection for the working tube), causing misoperation and accidents. Moreover, since the traditional fingerboard device uses a single motor to control a single opening and closing lever, t...

Abstract

The invention provides an automatic finger beam device. The automatic finger beam device comprises a drive finger beam, a finger beam body, protection pins and a drive assembly. A work pipe is arranged in the finger beam body, the finger beam body is provided with a plurality of sliding ways, the protection pins penetrate through the sliding ways, the drive finger beam is provided with the drive assembly, the drive assembly controls the protection pins to enter and stretch out of the sliding ways, and accordingly the work pipe is fixed or released. According to the automatic finger beam device, work pipe limiting fixing and releasing can be automatically achieved.

Description

technical field [0001] This application relates to but not limited to the field of offshore drilling platform equipment, especially an automatic finger beam device. Background technique [0002] During the drilling and tripping process of the drilling platform, it is necessary to continuously take out the working pipe (drill string, drill pipe, etc.) from the finger beam and move it to the wellhead; Limit the drill string. At present, the finger beams of conventional second-floor platforms are generally equipped with hanging chains or pallets to limit the position of the drill string. It is necessary for the derrick worker to cross the 26-meter-high gap between the monkey platform and the finger beam to disassemble and assemble the chains or reverse the clamping. Board, this kind of operation is labor-intensive and has high operation risk. Contents of the invention [0003] The present application provides an automatic finger beam device, which can realize the limit fixa...
