The pipeline butt joint tool provided by the invention is simple in structure and convenient to use, adopts a combined chain plate structure and realizes the clamping of the tool by adopting the principle of polygonal circumscribed circles; the clamping plate of the clamping mechanism has certain rigidity, so that the clamping mechanism can prevent fastening deformation; the number of the chain plates 31 can be increased or decreased to adapt to pipelines with different specifications; the clamping tool adopts a symmetrical structure, so that the tension of the wire tightening mechanism can be balanced, and the phenomenon that the pipeline is deviated due to pulling is prevented, and the construction quality is influenced; the chain plate 31 of the clamping tool is a standard component, the interchangeability is strong, and one part can be replaced by another part at any time when being damaged; an actuating member in the clamping tool adopts a special design mode, so that the bolt is ensured to be vertically upward, and the purposes of fastening and clamping are facilitated; meanwhile, according to the polygon circumscribed circle theory, the more the number of the chain plates 31 is, the larger the contact area is, the structure of the chain plates 31 is small, the contact area can be effectively increased, so that the friction force is increased, and the tool is prevented from sliding; the chain plate 31 is made of spring steel, can be deformed by force to increase the coating contact area, thereby increasing the friction force and preventing the tool from sliding. The pipeline section 1 is not easy to slip after being clamped, and when the pipeline section 1 is pulled along the axial direction, the pipeline section 1 is more stable in movement, so that accurate butt joint between the pipeline sections 1 is facilitated.
Example 2
This embodiment is substantially the same as embodiment 1 except that:
as shown in fig. 16, the pulling grip tool 110 is comprised of two slips 111, the slips 111 including an upper slip and a lower slip; after the upper slip and the lower slip are butted and tightly hold the pipeline section 1, fastening connection is carried out by utilizing fasteners such as bolts, nuts and the like; the upper slips and the lower slips are provided with connecting pieces (such as pulling pins, rings or hooks) for axially pulling the pipeline section 1; preferably, several connections are evenly distributed in the circumferential direction of the pipe section 1. The manufacturing cost of this embodiment is lower than that of embodiment 1.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
