Description

Butt joint device and method for pipeline equipment

Technical Field

The invention relates to the field of pipeline butt joint, in particular to a butt joint device and method of pipeline equipment.

Background

The gas insulated power transmission line equipment (GIL) is used as a novel power transmission equipment capable of replacing high-voltage overhead lines, is widely used for high-voltage and ultra-high voltage power transmission in urban pipe lanes and tunnels, the GIL equipment can be arranged for tens of kilometers, the GIL line is usually formed by splicing a certain number of standard pipe sections, the length of the standard pipe sections can reach 18 meters, flange butt joint is adopted among the pipe sections, and a bolt fastening connection mode is adopted.

GIL pipe rack is mostly the tunnel of level or slight slope of capping structure, and GIL divides into three-phase vertical arrangement and installs and fix on the pipe rack lateral wall. The interior space of the pipe gallery is narrow, and large hoisting equipment such as an automobile crane cannot be used. As shown in fig. 1 and 2, it is common practice to punch and install two fixed hanging points on the top wall near the butt joint position of each GIL pipe section, lift the GIL pipe section by using a chain hoist and a hanging rope, manually control the position and posture of the pipe section by using a traction rope, lift the pipe section to a proper height, approach the mounting bracket and align the pipe section with the axis of the mounted GIL flange, manually pull the two butt joint flanges to close together, rotate and finely adjust the lifted pipe section, control the bolt hole of the two flanges to be penetrated by each other by using a positioning pin, install bolts and fasten the flange connection surface, fix the butt-jointed bus pipe section on the equipment bracket, and then start the next butt joint mounting cycle.

There are a number of inconveniences in the above-described operation, specifically: the installation of each hoisting unit requires that two fixed hoisting points are additionally arranged at the top of the pipe gallery; the pipe section is lifted slowly and synchronously by manpower through a chain hoist; the hoisting process requires manpower to continuously traction and control the position and the posture of the hoisting pipe section; the flanges are butted and close by manual traction, and when the upper layer is hoisted, the length of a lifting rope is very short, so that the traction force required by the flanges to close can be obviously increased, and the stable butting of equipment is seriously affected; because the hoisting pipe section is bound and lifted by the hoisting rope, the circumferential rotation cannot be realized, the position of the bolt hole needs to be controlled accurately during rope binding, and the bolt hole on the butt flange needs to be penetrated by means of reasonable matching adjustment of the locating pin and the chain hoist during butt joint.

Above adopts to install a plurality of fixed lifting hooks additional at pipe gallery top, with the manual hoist of chain hoist + lifting rope, but utilize the wobbling characteristics of lifting rope, carries out butt joint installation through the pipeline section that the manpower adjustment chain hoist was lifted, has following problem:

(1) Two fixed hooks are additionally arranged at the top of the pipe rack at each hoisting position, so that the preparation time is long and the operation is complex;

(2) The hoisting path during operation needs to bypass the butt joint position, and the path is continuously adjusted by manpower through the traction rope in the process, so that collision with the installed equipment is avoided, and the hoisting path can be smoothly butt-jointed after hoisting;

(3) The fixed lifting hook can only be arranged near the butt joint path, the position and the posture of the pipe section are continuously adjusted by manpower through the traction rope during the butt joint operation, and the operation stability is poor;

(4) The hoisting method can be smoothly carried out only under the condition that the height of the GIL equipment is larger than the distance from the top of the pipe gallery, and part of the environment does not have the operation capability.

Meanwhile, through related patent retrieval, through combined retrieval of the retrieval words of GIL, installation and butt joint, the following approximate patents are consulted, and the specific differences are as follows:
