Specific embodiment
The utility model relates to flange bolt fastenings to assist supporting tool, working end 2 and and work including having working hole 1
Make the handle 3 of the connection of end 2, end of the working hole 1 for bolt 5 to be tightened on mounting flange 4, it is important to, it is described
The bolt adjacent with bolt 5 to be tightened is auxiliary bolt 6 on flange 4, is additionally provided with and auxiliary bolt 6 on the working end 2
Matched via hole 7, the working hole 1, via hole 7 are respectively arranged at the both ends of working end 2, the Internal periphery of working hole 1 with
The outer profile of the end of bolt 5 to be tightened is equipped with.
Embodiment 1, as shown in Figs. 1-2, the bolt on flange 4 are hex bolts, and the setting of bolt 5 to be tightened is in auxiliary spiral shell
The right side of bolt 6.The left end of working end 2 is arranged in via hole 7, and the right end of working end 2, the front side of working end 2 is arranged in working hole 1
It is in gap setting between the outer diameter of pipeline, gap width 3-8mm prevents working end 2 and pipeline from interfering.The via hole 7 is
Circular hole, and the diameter of via hole 7 is convenient for via hole compared with the end big 2mm of maximum circumscribed circle of the end hexagon of auxiliary bolt 6
7 are set in the end of auxiliary bolt 6.The supporting tool with a thickness of 10mm, steel plate self-control or raw using forging type can be used
It produces.
When work, bolt 5 to be tightened, auxiliary bolt 6 are pre-fixed on the flange 4 of pipeline, will be in the supporting tool
Via hole 7, working hole 1 respectively correspond auxiliary bolt 6, bolt to be tightened 5 and are arranged, due to auxiliary bolt 6, spiral shell to be tightened
Bolt 5 limits the both ends of working end 2 respectively, prevents the supporting tool from rotating, and is effectively prevented and is applicable in pneumatic pull
The generation of the accidents such as operating personnel's clamp hand or high falling when machine fastens bolt 5 to be tightened；Working hole 1 and bolt 5 to be tightened
The attached shape in end is treated fastening bolt 5 and is limited, and in the case where the supporting tool cannot rotate, working hole 1 will not be sent out
Raw rotation, that is, the limitation for treating fastening bolt 5 is reliable and stable, prevents bolt 5 to be tightened from rotating, keeps pneumatic trigger fast
Fastening bolt 5 is treated fastly to be fastened one by one, the installation of pipeline is fast implemented, and has not only reduced dangerous generation, but also improve
Working efficiency.
Embodiment 2 is another embodiment of the utility model, and as in Figure 3-5, the both ends of working end 2 are respectively by axis
The line articulated shaft 8 parallel with the axis of working hole 1 is hingedly provided with mounting rod 9, and working hole 1, via hole 7 are respectively by activity
Limiting device is set to the end of mounting rod 9, and working hole 1, via hole 7 have by mobile limiter along own axes respectively
The freedom degree of rotation, wherein via hole 7 is identical as the shape of working hole 1, either counterclockwise or clockwise to the spiral shell on flange
Bolt is fastened one by one.Working hole 1, via hole 7 can realize different distance by the mounting rod 9 hinged with working end 2
Adjustment, spacing can be such that working hole 1, via hole 7 rotates along own axes by mobile limiter after adjusting, to adapt to bolt
Hexagon end, hole 1 is worked at the same time, via hole 7 is arranged on mounting rod 9 by mobile limiter, according to different big
Small bolt is replaced the mobile limiter with working hole 1, via hole 7, can satisfy a variety of spacing, plurality of specifications
Bolt installation requirement.Wherein working end 2 is set to the periphery of flange 4, prevents from generating interference with flange 4.
Mobile limiter includes gear 10, is set to the end of mounting rod 9 and the mating ring gear 11 engaged of gear 10,
Working hole 1, via hole 7 are respectively arranged on gear 10 and are arranged concentrically with gear 10, by gear 10 by being removed on mounting rod 9, with
It is subjected to rotation adjustment with the end of corresponding bolt 5 to be tightened, auxiliary bolt 6, make the working hole 1 or auxiliary on gear 10
Help hole 7 that can be set in the end of bolt, then by 11 sets of ring gear of 9 end of mounting rod on gear 10, gear 10 with it is interior
Gear ring 11 is mutually limited, and is prevented gear 10 from rotating along own axes, that is, is treated fastening bolt 5, auxiliary bolt 6 is limited
Prevent bolt from rotating.
Further, convex edge 12 is set far from one end of flange 4 in gear 10, the end of mounting rod 9 is provided with and convex edge
12 is mating and inner wall on set threaded groove, groove is by the limit in 13 shape mated gear of threaded cap, 10 axial direction screwed with it
When installation, gear 10 is entered in ring gear 11 along groove for position, and convex edge 12 is fitted in the bottom of groove, is revolved using threaded cap 13
Enter in groove and carry out axial limit to the convex edge 12 on gear 10, prevents gear 10 from falling, use more safely may be used
It leans on, the end of threaded cap 13 is provided with knob, convenient for screwing to threaded cap 13.Also settable through-hole on threaded cap 13 leads to
The diameter in hole is greater than the external diameter of a circle of bolt end, can intuitively see internal bolt end.
