Problems solved by technology

[0002] The blowout prevention box is a tool to prevent the drilling fluid in the lifted drill string from overflowing and polluting the drill floor when the thread of the joint is unloaded when the drill is pulled out. The steel wire rope for traction passes through the rubber core in the blowout prevention box and frequently The rubber core slides, so the rubber core wears quickly and needs to be replaced frequently. However, the existing blowout preventer box must first remove the access assembly, and then remove the rubber core from the top of the box body and replace it. The operation is troublesome and time-consuming; and The replacement of the rubber core is an overall replacement, and the cost is relatively high; in addition, the existing blowout preventer only has a pulley to cooperate with the steel wire rope.

Abstract

The invention relates to a blowout preventing box. The blowout preventing box comprises a box body, first flying rings, a connecting assembly, an output assembly and a rubber core. The first flying rings are arranged on the left and right sides of the box body symmetrically. The connecting assembly and the output assembly are arranged at the upper and lower ends of the box body correspondingly. The rubber core is arranged in the box body. According to the blowout preventing box, first windows are formed in the front and rear sides of the box body correspondingly, two pumping rubber sheets arefast taken out and replaced by means of two detachable rubber base glands, operation is easy, time and labor are saved, and besides, the cost is saved; and moreover, two pulleys are arranged on the box and matched with a steel wire rope, accordingly, the blowout preventing box is prevented from skewing when the steel wire rope is pulled, and in addition, the wear rate of the rubber core is greatlydecreased.
