Quick connecting auxiliary device for high-pressure manifold of fracturing truck

Abstract

The invention discloses a quick connecting auxiliary device for a high-pressure manifold of a fracturing truck, and mainly aims to solve the problems of low assembly efficiency and high labor intensity of the high-pressure manifold of the oilfield fracturing truck in the prior art. The device is characterized in that a rotary support (1) is connected to a straight pipe column (2), the straight pipe column (2) is connected to a horizontal straight pipe A (4) through a fixed high-pressure elbow (3), the horizontal straight pipe A (4) is connected to a straight pipe through a sealed rotary shaftA (7) and an elbow, and the straight pipe is connected to a horizontal straight pipe B (10) through a sealed rotary shaft B (8) and an elbow; and the horizontal straight pipe B (10) is connected to asealed rotary shaft D (12) through a sealed rotary shaft C (11) and an elbow, the sealed rotary shaft D (12) is connected to a sealed rotary shaft E (13) through an elbow, and the sealed rotary shaftE (13) is connected to a high-pressure interface (14). By adopting the quick connecting auxiliary device for the high-pressure manifold of the fracturing truck, the labor intensity of workers is greatly reduced, the assembly efficiency is improved, and the accurate abutting joint is realized.

Description

technical field [0001] The invention relates to the field of oil fields, in particular to a quick-connect auxiliary device for a high-pressure manifold of a fracturing vehicle. Background technique [0002] All high-pressure equipment in the oil field needs to use high-pressure steel pipes to connect the equipment to the wellhead. Due to the high pressure of the manifold, thick-walled pipe fittings must be used. A set of manifolds has a dead weight of more than 500kg. Straight pipes are assembled on site. At present, the hard pipe connection method is used for assembly. The relative positions of the fracturing equipment and the wellhead are randomly placed according to the actual situation on the job site. It is necessary to combine multiple sets of elbows and straight pipes to realize the connection between the fracturing equipment and the wellhead. Large, low work efficiency, at least 3 people are needed to cooperate, and it takes at least 10 minutes to complete the conne...
