Abstract

The invention discloses a chain ring blowout preventer lifting and transferring device. The device comprises a guide rail, travelling trolleys, a reduction gearbox, a motor, wheels, a ring chain hoist, a hooking rack, a connecting shaft, a control cabinet, a chain box, a control pipeline and a power pipeline. The device is characterized in that front and rear two travelling trolleys are arranged on the ring chain hoist, and are connected with the ring chain hoist by virtue of the connecting shaft; wheels are arranged on the inner sides of the travelling trolleys, and are suspended over the guide rail; and the ring chain hoist is of a steel plate welded integral structure, and joint bearings and safety lugs are arranged at two ends of the ring chain hoist. The ring chain blowout preventer lifting and transferring device has the advantages of compact structure, good no-voltage brake performance, strong corrosion resistance, flexible operation, large lifting force and stable operation.

Description

technical field [0001] The invention belongs to the technical field of lifting devices for petroleum exploration equipment, and in particular relates to a lifting device for chain-type blowout preventers. Background technique [0002] The blowout preventer lifting device is a kind of lifting equipment specially used for drilling rigs. When drilling deep wells, it is necessary to configure blowout preventers to ensure safety. Due to the limited space at the wellhead, it is often in harsh environments such as overtime and mud pollution for a long time, and it is necessary to lift and replace the blowout preventer and casing many times. It is required that the lifting device must be safe and reliable, suitable for harsh environments, small in size, large in lifting force, and easy to install and maintain. However, in the prior art, the similar lifting device has a large structure, poor pressure loss braking performance, poor corrosion resistance, and inflexible operation. The ...
