Detailed Description
The pipeline aligning device mainly comprises three parts, wherein the first part is a main body frame, the second part is a circle supporting device, and the third part is an aligning device.
The following details the structure of these three parts:
1. main body frame
As shown in fig. 1 and 2, the part consists of a circular framework 1 and a walking part 2. The circular frame 1 is formed by welding H-shaped steel, the circular frame 1 is a main stress member for supporting a pipeline, and the whole circular frame is required to have enough rigidity.
The walking part 2 also bears the weight pressure of the circular framework as the lower part of the main body framework, so the width of the walking part designed by the invention is larger than that of the circular framework. This widening is an axial widening.
The bottom of the walking part is provided with a walking wheel 3, and the installation direction of the walking wheel 3 is that the radial central line of the walking wheel points to the center of the circular framework 1 so as to facilitate the straight walking in the pipe. The travelling wheel 3 may be a rubber wheel with a diameter of 100 mm.
The diameter of the main body frame is adapted to the diameter of the pipeline to be adjusted, for example, for a large pipeline with a diameter of 2200mm, the circular framework provided by the invention has an outer diameter of 1800mm and an inner diameter of 1200mm, the upper circular framework 1 has a width of 200mm, and the lower walking part 2 has a width of 500mm.
2. Circle supporting mechanism
The circle bracing mechanism 4 includes a circle bracing plate 42 and a first jack 41. The round supporting mechanisms are uniformly fixedly connected to the main body frame, and the deformation of the pipeline is modified from the inner supporting pipe orifice. The more the number of the rounding mechanisms 4 is, the more the pipeline opening is modified to be rounded, and the more accurate the pipeline opening is. However, the more the number of the circle supporting mechanisms 4 is, the larger the load of the whole device is, and the heavier the load of the circular framework 1 is, so that the number of the circle supporting mechanisms 4 is reasonably set according to working conditions.
As shown in fig. 3-5, in one example provided by the present invention, the number of first jacks 41 is five, and the first jacks are uniformly fixed on the main body frame. Because the jack of the circle supporting mechanism collides with the position of the H-shaped web 11 (the position where the web is located is the position where the circle supporting mechanism is best installed), the web 11 is reformed, the web 11 and the upper flange plate 12 at the position where the first jack 41 is to be installed are cut, a jack installation opening is manufactured, reinforcing rib plates 5 are additionally arranged on two sides of the jack installation opening, the first jack 41 is installed in the installation opening, the reinforcing rib plates 5 are placed between the two rib plates and fixed, and then the cut flange plate is recovered.
A supporting circular plate 42 is welded on top of each first jack 41, wherein the supporting circular plate 42 is 150mm steel plate with radian. The first jack 41 is arranged radially, and the supporting circular plate 42 can be controlled by the first jack to extend and retract radially outwards.
3. Opposite opening mechanism
As shown in fig. 6, 7 and 8, the centering mechanism 6 is mounted on the upper flange plate 12 of the main body frame so as to be slidable along the upper flange plate 12. The hydraulic lifting device comprises a crawling frame 61, wherein two jacks, namely a jack A64 and a jack B65, are arranged on the upper portion of the crawling frame 61, and the tops of the jack A64 and the jack B65 are fixedly connected with a square steel 66. The square steel 66 has a flat surface, and is used for checking whether the butt joint of two pipelines is flat or not when in use. The jack A and the jack B are independently controlled, and the control can be controlled by the control degree or manually. During construction (refer to fig. 9), the square steel 66 is pressed at the joint of the two pipelines, and when the pipes at the joint are not aligned, the jack A or the jack B lifts the pipeline wall on the corresponding side surface, locally pushes the pipe orifice outwards, and aligns the edges of the two pipelines.
The crawling wheel is arranged at the bottom of the crawling frame 61 of the aligning mechanism 6, the crawling wheel comprises two types of rollers 63 and permanent magnet wheels 61, the rollers 63 are clung to the outer surface of the upper flange plate 12, the permanent magnet wheels 61 are clung to the inner surface of the upper flange plate 12, the rollers 63 and the permanent magnet wheels 61 clamp the upper flange plate, and the upper flange plate walks along a track.
When the centering mechanism is assembled, the crawling frame 61 and the rollers 63 are placed on the upper flange plate 12, then the permanent magnet wheels 61 are installed, the lower chord plates are arranged on two sides of the crawling frame, and the permanent magnet wheels are connected with the lower chord plates through bolts. The permanent magnet wheels and the rollers are matched to clamp the upper flange plate, so that the crawling frame is installed on the upper flange.
When the aligning mechanism is used, the crawling frame is manually pushed to move along the circumference on the upper flange. The jack A and the jack B are set to be manual.
The docking mechanism may be provided in two, preferably an upper half (i.e. where the main body frame is 200mm wide) and a lower half (i.e. where the main body frame is 500mm wide).
The construction method for butting the pipelines by using the large-diameter pipeline butting device comprises the following steps:
1) The device is pushed to the pipe orifice, the pipe is manually pushed to the opposite position, and the travelling wheels straddle the pipes on the two sides to be butted.
2) And starting a circle supporting mechanism to support the whole pipeline.
3) And (3) independently adjusting each first jack, lifting the local position of the pipeline, and adjusting the overall roundness of the pipe orifice.
4) Checking the roundness and the offset of the pipe orifice.
5) If the misalignment amount is larger, the aligning mechanism is arranged on the frame, the aligning mechanism is pushed to the position with larger misalignment amount of the pipeline, the jack A or the jack B is started, the misalignment amount is adjusted to an allowable value and then welded and fixed, then the next position is moved to continue to be aligned, and the aligning mechanism is taken down after the alignment is finished.
6) The circle supporting mechanism is fallen down to be pushed to the butt joint position of the next pipe orifice, if the circle supporting mechanism is touched in the moving process, the circle supporting mechanism is retracted, and when the butt joint mechanism reaches the next working face, the circle supporting mechanism is re-supported.
The device can correct the shape of the butt joint before the butt joint of the pipelines, provides support for the walls of the pipelines during butt joint welding, ensures that the butt joint is neat, and is welded under the support of the butt joint mechanism, so that the operation is very convenient. The device solves the problems of the prior art that the construction method adopting wedge alignment reduces the labor intensity of workers, improves the construction efficiency, reduces the material use and reduces the cost.
