Integral remote pipe flange bolt connection implement

Abstract

The invention provides an integrated, remote-controlled, self-aligning screw hole, flange hole alignment, nut-bolt connection and pre-tightening pipe flange bolt connection machine, which consists of an outer frame, an inner The outer frame is the base of the whole tool, which can be self-positioned on the pipeline through the claws at both ends; the inner frame includes a rotating body, and the rotating body and the outer frame are connected by a chute, and the two rotating bodies are fixed. Two linear guide rails are connected, and the two ends of the guide rails are fixedly connected to the fixed seat. The hydraulic swing cylinder on the outer frame drives the rotating body to drive the inner frame to rotate around the central axis of the pipeline; On the two guide rails of the frame, the opening and closing movement is driven by the telescopic mechanism on both sides. Two half bolt tensioners and nut driving devices are installed on the bolt magazine; the nut tightener is embedded in the nut magazine. The axial driving device is connected between the fixed seats on the top and can slide along the guide rail.

Description

(1) Technical field [0001] The invention relates to an automatic mechanical operation tool, specifically an integrated, remote-controllable pipeline flange capable of self-aligning screw holes, aligning flange holes, and realizing the connection and pre-tightening of nuts and bolts. Bolted implements. (2) Background technology [0002] The flange automatic connection system mainly has three connection methods, namely bolt connection, clamp connection and collet connection. All three methods are suitable for underwater pipe connections without diver assistance. Among them, the bolt connection has irreplaceable advantages and wide application. For example, in the special environment of deep water and high pressure in the ocean, the sealing and durability of the pipeline connection are very high, and the flange mechanical connection of the submarine pipeline often adopts the bolt connection method. Pipeline connection To put it simply, on the seabed, a series of docking equip...

Problems solved by technology

However, in these schemes, both the nut storehouse and the bolt storehouse move independently in the circumferential direction, and the number of hole alignments is high. Due to the high difficulty in aligning the bolts and nuts, the split design of the two storehouses requires the control accuracy of the entire set of equipment and the requirements for the observation device. higher
