Description

Technical Field

[0001] This utility model relates to the field of winch anti-collision technology, specifically an anti-collision structure for oil drilling rig winches. Background Technology

[0002] The winch of an oil drilling rig is a crucial working component, primarily used for raising and lowering drill strings, running casing, controlling drilling pressure during the drilling process, and erecting the derrick as a whole. It provides power and control mechanisms, enabling the drill strings to perform drilling operations efficiently.

[0003] A winch typically consists of a power unit, a transmission mechanism, drums, a clutch, and brakes. The drums are one of the core components of the winch, responsible for winding or releasing the wire rope to lift or lower heavy objects. The braking system controls the winch's stopping and braking, ensuring the safety of drilling operations.

[0004] Oil drilling rig winch systems typically employ pneumatic braking systems. The advantages include simple structure, minimal need for disassembly of most pneumatic components during relocation and installation, ease of installation and disassembly, durability, ease of maintenance, and the absence of precision components, resulting in lower system investment and operating costs. However, a disadvantage is that when the main air circuit switch of the winch is disconnected, the pneumatic clutch on the winch drum cannot immediately disengage, causing the winch drum to fail to engage the brakes promptly, which can easily lead to collisions.
