Abstract

The invention relates to the technical field of protection devices, and provides a power-failure protection device used for a drilling rig and a power-failure protection type drilling rig drum device.The power-failure protection device used for the drilling rig comprises a normally-open pneumatic control valve, a source gas inlet pipeline, an electromagnetic valve, a high and low speed gas guidevalve, a pneumohydraulic reversing valve, a master clutch gas guide valve, a control gas pipeline, a low-speed pneumatic reversing valve and a high-speed pneumatic reversing valve, wherein an gas outlet of the source gas inlet pipeline is communicated with a first normally-open interface of the normally-open pneumatic control valve through the control gas pipeline, and the electromagnetic valve isarranged in the control gas pipeline. The power-failure protection type drilling rig drum device comprises the power-failure protection device used for the drilling rig, a main drum, a hydraulic pipeline, a third master gas guide pipeline, a fourth master gas guide pipeline and a central shaft. The power-failure protection device is reasonable and simple in structure and convenient to use, by arranging the electromagnetic valve in the control gas pipeline, the drilling rig can be quickly comprehensively braked in an unexpected power failure, drill string not-well braked and free-fall accidents are avoided, the operation safety of the drilling rig is improved, and the power-failure protection device has the advantages of being safe, simple and reliable, and saving labor.

Description

technical field [0001] The invention relates to the technical field of protection devices, and relates to a power-off protection device for a drilling rig and a power-off protection type drilling rig roller device. Background technique [0002] Oil and gas drilling rigs often experience power outages at the well site due to various reasons such as generator failures and power distribution room failures. If the brakes are not taken in time and the normal operation is continued, accidents such as slipping and stopping of drilling will occur, which is very dangerous. Contents of the invention [0003] The invention provides a power-off protection device for a drilling rig and a power-off protection type drilling rig roller device, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem that the existing drilling rigs continue to work after a power failure, which is prone to slipping and drilling. Accidents such as dun drilling...
