Detailed Description

The technical scheme of the utility model is further described below with reference to the specific embodiments:

As shown in FIG. 1, the connecting and dismounting device for the hexagonal screwed connection connecting pipe in a narrow space comprises a hexagonal screwed connection dismounting tool 1 and a tool inner sleeve 2, wherein an opening is formed in the hexagonal screwed connection dismounting tool 1, a groove 14 and a plurality of prying holes 11 are formed in the outer circumference of the hexagonal screwed connection dismounting tool, the groove 14 is used for increasing the tightness of the tool in use, the hexagonal screwed connection dismounting tool 1 comprises a large end sleeve part and a small end handle part, the outer diameter of the large end sleeve part is 70-75 mm, the length is about 50mm, the outer diameter of the small end handle part is 50-55 mm, the length is about 100mm, and the whole hexagonal screwed connection dismounting tool 1 is made of PVC materials for weight reduction. As shown in fig. 3, six clamping grooves 13 with the depth of 20mm are formed in the inner side circumference of the large end sleeve part, as shown in fig. 4, the tool inner sleeve 2 is in a funnel shape, the height is 35-40 mm, six convex grooves 22 matched with the clamping grooves 13 are formed in the outer side of the tool inner sleeve 2, an inner hexagonal hole is formed in the inner side of the tool inner sleeve 2, and the size of the inner hexagonal hole is matched with a clamping sleeve nut, a flat shoulder nut and a cable stuffing box nut which need to be disassembled and assembled. Considering that the tool inner sleeve 2 is stressed to wear when the cutting sleeve joint, the flat shoulder joint and the cable stuffing box of the small-caliber pipe are disassembled, the tool inner sleeve 2 is made of steel materials.

In order to ensure that the small-diameter pipe and the cable can be sleeved into the hexagonal screw joint dismounting tool 1, as shown in fig. 3, a tool side groove opening 12 with a circumferential angle of 35 degrees is formed in the whole length range of the hexagonal screw joint dismounting tool 1. An inner sleeve side groove opening 21 with a circumferential angle of 35 degrees is formed in the whole length range of the tool inner sleeve 2, and the position of the inner sleeve side groove opening 21 is aligned with the tool side groove opening 12. The diameter of the opening inside the hexagonal threaded joint dismounting tool 1 is 30-35 mm, and is 5-10 mm larger than the diameter of the pipe and the cable 3 to be dismounted.

As shown in FIG. 1, the application method of the connecting wire dismounting device for the hexagonal threaded connection pipe in the narrow space comprises the following steps:

Step one, according to the opposite side diagonal sizes of a hexagonal nut of a pipe cutting sleeve joint, a flat shoulder threaded joint and a cable stuffing box to be assembled and disassembled, selecting a tool inner sleeve 2 with matched types and specifications, inserting the tool inner sleeve 2 into a large end sleeve part of a hexagonal threaded joint disassembly tool 1, aligning a side groove opening on the tool inner sleeve 2 with a side groove opening of the hexagonal threaded joint disassembly tool 1 when the tool inner sleeve 2 is inserted, and fully inserting six convex grooves 22 on the outer side of the tool inner sleeve 2 into six clamping grooves 13 of the large end sleeve part of the hexagonal threaded joint connecting pipe wiring disassembly tool;

And secondly, the small-caliber pipe cutting sleeve joint is arranged between bulkheads, the construction space is very limited, the cutting sleeve connecting nut cannot be disassembled or tightened by using an open spanner, and the pipe and the cable cannot be sleeved into the sleeve to screw and disassemble the nut because the pipe and the cable are not disassembled. The method comprises the steps that a connecting pipe wiring threaded joint dismounting device is used, a side groove opening of the whole device faces to a small-caliber pipe or a cable, and the connecting pipe wiring threaded joint dismounting device is wrapped on the small-caliber pipe or the cable;

Step three, because the operation area is relatively narrow, visual operation cannot be performed, the whole set of connecting pipe wiring threaded joint dismounting device can only be lifted upwards and the corner position can be adjusted by means of feeling until a clamping sleeve joint, a flat shoulder joint or a hexagonal connecting nut of a cable stuffing box connected with a pipe is sleeved in an inner hexagonal hole of the tool inner sleeve 2;

Step four, after the tool inner sleeve 2 is sleeved into the nut, the hexagonal threaded connector dismounting tool 1 is screwed clockwise by hand, so that the clamping sleeve connecting nut is screwed up to the screwing-up position, if the space is relatively large, a prying bar can be used for plugging into a prying hole 11 of the hexagonal threaded connector dismounting tool 1 to assist screwing or unscrewing the nut, and the mounting or dismounting process is completed.

The present embodiment is further illustrative of the present utility model and is not to be construed as limiting the utility model, and those skilled in the art can make no inventive modifications to the present embodiment as required after reading the present specification, but only as long as they are within the scope of the claims of the present utility model.
