Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the drawings and the embodiments.

Referring to the accompanying drawings 1-4, the multi-pipeline coaxiality adjusting device comprises a platform for sequentially arranging a plurality of pipelines along the axial direction, and adjusting mechanisms for adjusting the coaxiality of the pipelines and a standard axis are symmetrically arranged on two sides of the platform along the axial direction at intervals. The action principle of the adjusting device is as follows: a plurality of pipelines (generally, preferably with the same specification, shown as 10 in the figure) are sequentially placed on the platform end to end along the length of the platform, the axes of the corresponding pipelines are adjusted through a plurality of adjusting mechanisms, finally, the axes of all the pipelines placed on the platform are all located in relatively accurate standard axes, the coaxiality of the pipelines is improved, after adjustment is completed, the adjacent pipelines are fixed (including a welding mode and the like), and the pipelines are connected into a long pipeline with high coaxiality. Through adjustment of the adjusting mechanism, the whole long pipeline formed by the single pipelines has higher axial linearity, and vibration caused by deflection during later use, particularly rotation, of the long pipeline is reduced, so that the stability of rotation of the long pipeline is improved.

Specifically, the platform is composed of support rods 1 (preferably, a long straight rod structure with a smooth surface) which are arranged in parallel and symmetrically at the same height, a placing space 101 for the pipeline is formed between the symmetrical support rods 1, the pipeline is placed in the placing space 101, and the peripheral surfaces of the two sides of the pipeline are in contact with the near sides of the symmetrical support rods 1. Place many pipelines in proper order in placing space 101 to make pipeline bottom both sides all with the 1 lateral wall contact of bracing piece about, support the pipeline, because bracing piece 1 selects smooth long straight rod structure, it has had the higher straight line structure of plane straightness accuracy, consequently finely tunes the regulation that can reach many pipeline axiality through adjustment mechanism. According to the arrangement of the prevention mode of the platform, when the axis of a single pipeline is adjusted, the pipeline moves up and down and left and right as required, so that the axis of the pipeline is close to a standard axis. Therefore, the adjusting mechanisms are arranged outside the supporting rods 1 and act on the circumferential surface of the pipeline, and the position of the pipeline is effectively adjusted.

In the actual manufacturing process, each pipeline has different process structures (for example, perforations are formed at different positions), so that each pipeline has a correct rotation position, and the contact surface of each support rod 1 and the pipeline is set to be an arc surface 1 a. Place the pipeline place in placing space 101 and with bracing piece 1 contact back, exert external force to the pipeline and rotate, at rotatory in-process, because the contact surface of bracing piece 1 and pipeline is arc surface 1a, has less area of contact and rotational friction between the two, consequently, arc surface 1a is favorable to the rotatory demand of pipeline.

Specifically, the adjusting mechanism comprises a supporting plate 2 arranged on the side wall of the supporting rod 1, an adjusting rod 3 advancing towards the circumferential direction of the pipeline penetrates through the supporting plate 2, one end, close to the pipeline, of the adjusting rod 3 is adjustably hinged to an acting plate 4, and the acting plate 4 is provided with a horizontal acting end 4a and a vertical acting end 4b acting on the pipeline. As described above with the method of adjusting a single pipe to a standard axis, it is necessary to move the pipe to an arbitrary position within its radial surface, and therefore it is particularly operative to: if the height of the pipeline needs to be adjusted, as shown in fig. 3, the action plate 4 needs to be rotated at the hinge joint, so that the vertical action end 4b is tightly attached to the outer wall of the pipeline, the horizontal action end 4a is separated from the contact with the outer wall of the pipeline, and then the adjustment rod 3 moves and adjusts relative to the support plate 2, so that the vertical action end 4b drives the pipeline to ascend or descend, and the up-and-down movement of the pipeline axis gradually coincides with the standard axis. If the horizontal position of the pipeline is to be adjusted, as shown in fig. 4, the mode is the same as the height adjustment, the action plate 4 is rotated to enable the horizontal action end 4a to be tightly attached to the outer wall of the pipeline and the vertical action end 4b to be separated from the contact with the outer wall of the pipeline, then the adjustment rod 3 moves and adjusts relative to the supporting plate 2, the horizontal action end 4a drives the pipeline to move left and right, and the axis of the pipeline is gradually overlapped with the standard axis. Preferably, the adjustment lever 3 is preferably an adjustment bolt that is moved relative to the support plate 2 by rotating the adjustment bolt. In order to avoid the problem that the adjusting screw rotates to drive the acting plate 4 to rotate, the connecting cylinder 6 is arranged between the hinge joint and the adjusting bolt, preferably, the end part of the adjusting bolt is rotatably connected with the connecting cylinder 6, namely, the connecting cylinder 6 and the acting plate 4 do not rotate along with the adjusting bolt when the adjusting bolt is rotated. Preferably, a fastening bolt 7 is inserted at the hinge joint between the connecting cylinder 6 and the acting plate 4 so as to realize adjustable hinge joint of the acting plate 4, and the horizontal acting end 4a and the vertical acting end 4b are conveniently contacted with the outer wall of the pipeline independently according to requirements. And particularly before placing the pipe into the placing space 101, it is preferable to raise the position of the acting plate 4 first so that the pipe first comes into contact with the acting plate 4 to fulfill the need for the pipe to fall.

In order to realize the placement of pipelines with different outer diameters, the platform further comprises adjusting screw rods 5 which are vertically arranged at two ends of the supporting rod 1 in a penetrating mode and used for adjusting the width of the placement space 101. Preferably, the adjusting screw 5 has opposite symmetrical helical teeth on the left and right sides, and when the adjusting screw is rotated, the support rods 1 on the two sides can be simultaneously moved toward or away from each other, so as to adjust the size of the accommodating space 101. Preferably, the adjusting device comprises a bracket 8, and the adjusting screw 5, the support rod 1 and other components are arranged on the bracket 8 for supporting.

The principle of the utility model is as follows: a plurality of pipes are placed in the placing space 101 in sequence end to end along the length of the platform and in contact with the action plate 4. According to different pipeline adjusting modes, the contact ends of the action plate 4 and the pipelines are adjusted to realize position adjustment of the pipelines in a radial plane, finally, the axes of all the pipelines placed on the platform are located in relatively accurate standard axes, the coaxiality of the pipelines is improved, and after adjustment is completed, adjacent pipelines are fixed (including a welding mode and the like), so that the pipelines are connected into a long pipeline with high coaxiality. Through adjusting different contact ends of the action plate 4, the integral long pipeline formed by a plurality of single pipelines has higher axial degree, and the vibration caused by the deflection of the long pipeline in later use, particularly rotation, is reduced, so that the stability of the rotation of the long pipeline is improved.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
