Description
Technical Field
The invention relates to the technical field of drilling derricks, in particular to an oil drilling derrick structure.
Background
The derrick is used for placing crown blocks, hanging tools such as traveling wagons, hooks, hanging rings, hanging clips and the like, and storing drill rods, oil pipes and sucker rods in the well drilling or well repairing process. The derrick consists of a main body, a crown block, a racking platform, a riser platform and a working ladder, and is mainly divided into a tower-shaped derrick, a front opening derrick, an A-shaped derrick and a mast-shaped derrick. When the oil field drilling operation encounters emergency dangerous situations such as blowout, fire or strong wind, the vertical climbing ladder or inclined ladder cannot be used for escaping, and derrick operators generally escape through a derrick racking platform. In the prior art, in the escape process, a safety rope is required to be fastened, a multifunctional safety belt is threaded, a manual controller above the safety belt is screwed up, a hook of the manual controller is hung on a hanging ring of the safety belt, the safety rope is loosened, after the fact that the manual controller is effective is confirmed, a body is separated from a derrick, and the manual controller is loosened, so that the body keeps even speed and slides downwards. In the above preparation work before the body leaves the derrick, a certain time is required. When actually encountering danger, each minute is precious, and delaying one minute can directly threaten life safety.
Disclosure of Invention
The invention provides an oil drilling derrick structure for shortening the escape time of a derrick racking platform, which aims to overcome the defect that the earlier preparation work is too long in the escape process of the derrick racking platform.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
