Abstract

Disclosed is a flange dismounting anti rotary wrench, a bolt passes through a flange, a nut is connected with the bolt, a sleeve wrench covers on the nut, an adjusting sleeve covers upon the sleeve wrench, on end of a folded rod is welded on the adjusting sleeve, the other end of the folded rod is welded on a square sleeve, the upper part of an assistant wrench is covered in the square sleeve, the lower part of the assistant wrench is clamped at the head of the bolt. The assistant wrench can not rotate because it is blocked by another group of bolts on the flange when using. Rotate the sleeve wrench to spin the nut in need of dismounting and assembling of flange bolts and nuts, bolts can not rotate under the assistant wrench action, and nuts and bolts can be connected to form one body or be split into two parts by the relative rotating of bolts and nuts. The integration of the sleeve wrench and the assistant wrench saves the installation of the rotary wrench and workers who operate the anti rotary wrench during dismounting and assembling of flange bolts and nuts, which is labor-saving and convenient and fast in dismounting and assembling of flange bolts and nuts, then the labor intensity can be reduced, as well as ensuring the quality of dismounting and assembling work.

Description

Flange dismounting anti-rotation spanner
One, technical field
The utility model is a kind of instrument of dismounting pipeline connecting flange, particularly a kind of flange dismounting anti-rotation spanner.
Two, background technology
The pipeline connecting flange is fixed into one by bolt, nut, at the scene need could be with its dismounting when dismounting flange bolt, nut with two spanners, one of them spanner is used to screw bolt, nut, spanner is used to prevent the bolt of the other end or nut in company with rotation, and two spanners need have operating personnel respectively holding up.Therefore, tool using is many when dismounting flange bolt, nut at present, and operating personnel are also many.When flange is in specific position, the bad installation of spanner, operating personnel's body is difficult to put in place, and the dismounting flange is inconvenience very, and labour intensity is big.
Three, summary of the invention
The purpose of this utility model is a kind of flange dismounting anti-rotation spanner of design, makes its dismounting flange bolt, nut convenient, fast.
The purpose of this utility model is achieved in that by bolt, nut, flange, box spanner to be formed, bolt is through on the flange, nut and Bolt Connection, box spanner is placed on the nut, regulating sleeve is sleeved on the box spanner, and pole one end is welded on the regulating sleeve, and the pole other end side of being welded on puts, in the side of being placed in, the secondary spanner top cover, secondary spanner bottom is stuck on the head of bolt.
The beneficial effects of the utility model are: box spanner and secondary spanner are assembled into one, make it when dismounting flange bolt, nut, not need to install again the personnel of anti-rotation spanner and operation anti-rotation spanner, the saving personnel, dismounting flange bolt, nut are convenient, fast, reduce labour intensity, the dismounting quality is guaranteed.
Four, description of drawings
Accompanying drawing is the installation diagram of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
Embodiment of the present utility model is made up of side's cover 1, secondary spanner 2, pole 3, bolt 4, nut 5, flange 6, box spanner 7, regulating sleeve 8, bolt 4 is through on the flange 6, nut 5 and Bolt Connection, box spanner 7 is placed on the nut 5, regulating sleeve 8 is sleeved on the box spanner 7, and pole 3 one ends are welded on the regulating sleeve 8, on pole 3 other end sides of the being welded on cover 1,1 li in the side of being placed in, secondary spanner 2 top cover, secondary spanner 2 bottoms are stuck on the head of bolt 4.
During use, secondary spanner 2 is stopped by another group bolt on the flange, can not rotate, when needing dismounting flange bolt, nut, turnbarrel spanner 7 makes nut 5 rotations, and bolt 4 can not rotate under the effect of secondary spanner 2, make bolt 4, nut 5 produce rotation relatively, thereby nut 5 and bolt 4 are connected into one or are disassembled into two bodies.
