Detailed Description
As shown in fig. 1 to 4, the present embodiment provides a detachable fastening device for a pipeline interface, which includes a nut frame 4, a chain 6, a threaded rod 3, a rotating handle 2, and a pressure pad 7. The left side of the nut frame 4 is hinged with one end of a chain 6 through a hinge 9, the right side of the nut frame 4 is provided with a clamping hook 5, and the other end of the chain 6 can be clamped on the clamping hook 5 after the chain 6 bypasses the interface position of a pipeline 8. The chain 6 comprises a plurality of pin shafts 10 which are sequentially arranged, a sleeve 14 is sleeved at the middle position of each pin shaft 10, and the sleeve 14 can rotate relative to the pin shafts 10. The adjacent pin shafts 10 are connected through chain plates (an inner chain plate 12 and an outer chain plate 13), the pin shafts 10 can rotate relative to the chain plates, the joints of the pin shafts 10 and the chain plates are positioned on two sides of a sleeve 14, and the tail ends of the pin shafts 10 are provided with assembling caps 11. The nut frame 4 is provided with a threaded hole, the threaded rod 3 is provided with an external thread, and the threaded hole is internally threaded with the threaded rod 3. The threaded rod 3 can rotate and move relatively along the threaded hole in the threaded hole. The outer end of threaded rod 3 can be dismantled and connect twist grip 2 to dismantle down twist grip 2 after screwing up threaded rod 3. The rotary handle 2 is used to manually apply torque to the threaded rod 3 to rotate. In this embodiment, the outer end of threaded rod 3 sets up assembly post 15, sets up the assembly mouth on twist grip 2, and the cross section of assembly post 15 and assembly mouth is square, and assembly post 15 joint is in the assembly mouth. The rubber sleeve 1 wraps the rotating handle 2, so that an operator can hold the rotating handle 2 conveniently, and the safety of operating the rotating handle 2 is improved. The pressure pad 7 is provided with a blind threaded hole, and the inner end of the threaded rod 3 is in threaded connection with the blind threaded hole. The tail end of the pressure pad 7 is a circular arc surface so as to be attached to the outer contour of the joint position of the pipeline 8.
The detachable fastening device for the pipeline interface of the embodiment has the following use process: after the other end of the chain 6 bypasses the interface position of the pipeline 8, the pin shaft 10 at the other end of the chain 6 is clamped on the clamping hook 5, the tail end of the pressure pad 7 is attached to the interface position of the pipeline 8, and the inner end of the threaded rod 3 is connected with the threaded blind hole in the pressure pad 7; the rotating handle 2 is operated to rotate, the threaded rod 3 moves towards the pipeline 8, the threaded rod 3 rotates in a threaded blind hole in the pressure pad 7 and applies pressure to the interface position of the pipeline 8 through the pressure pad 7, meanwhile, the nut frame 4 moves away from the pipeline 8, the chain 6 is gradually tensioned, and the chain 6 applies pressure to the whole interface position of the pipeline 8; the threaded rod 3 is continuously rotated, the pressure is gradually increased, so that the interface of the pipeline 8 is fastened, and the rotating handle 2 is disassembled; when the interface of the pipeline 8 is disassembled, the rotating handle 2 is connected with the assembling post 15 at the outer end of the threaded rod 3, and the threaded rod 3 is rotated towards the opposite direction.
