Description
Technical field
The present invention relates to engineering equipment mounting technique field, specifically one kind are used for ensureing that punching bolt two ends are stretched out
The gripping mechanism of equal length and method.
Background technology
In engineering equipment installation process, pipeline installation is very common, and flange connection is as a kind of common pipeline
Connected mode, specifically refers to be cast with flange at the two ends of pipeline joint, has seal groove, groove is built with sealing on end face of flange
Pipeline is tightly connected together with bolt or punching bolt by circle to after connecting.Flange connection is in electric power, oil and chemical industry
It is widely used in connecting etc. the pipeline of various fields, liquid can be connected with the pipeline being generally connected, these liquid
Body is oil or other danger industrial chemicals, such as contain cooling oil in the cooling oil path of high-power transformer, for constantly following
Ring is lowered the temperature to transformator.During Specific construction, because the use condition of these pipelines is all harsher, therefore it connects
Fitting adopts punching bolt, to ensure more preferable air-tightness.
But, in pipe installation process, as shown in figure 8, the installation of punching bolt lack of standardization, punching bolt two ends are stretched out
Length phenomenon different in size is especially prominent, and the length that some punching bolts stretch out nut is too short, or even only 2-3 pitch,
This kind of situation may result in the other end stretch out long.This is because, in installation process, punching bolt is installed using manual, Gong Ren
During construction, the extension elongation at punching bolt two ends being not easy to grasp although increasing inspection, peace can be improved in a small range
Dress effect.But, in concrete installation process, the pipeline being connected using flange is very many, is difficult to accomplish effective control, but also meeting
Increase the operation easier of installer.
The installation of punching bolt is lack of standardization to often lead to many quality problems；First, if to stretch out nut too short easily for bolt
It is unreliable to lead to connect, and has larger potential safety hazard；Secondly, for the equipment of design relatively specification, studs one end is stretched out
Long often subsequent installation generation is disturbed；Finally, the establishment to construction enterprises' high grade project target has large effect,
Because during high grade project evaluation, being embodied in details aspect in most cases, the multiple punching bolt two ends on a ring flange are stretched
Go out that length is different in size, here it is apparent details error, if being required again to dismount, often also resulting in sealing member and ruining
Bad, bring unnecessary loss.
Content of the invention
For in prior art, punching bolt is installed using manual, and workman stretches out to punching bolt two ends in construction
Length is not easy to grasp, and leads to punching bolt two ends extension elongation problem different in size, it is an object of the invention to provide one
Plant for ensureing the equal gripping mechanism of punching bolt two ends extension elongation and method, installation process accurately controls punching spiral shell
The extension elongation at bolt two ends, reaches uniform effect.
The present invention solves its technical problem and is adopted the technical scheme that：

On.
Further, described gland is fixedly connected on described second V-block by welding or mode connects for screw.
Further, described base bottom is provided with some counterbores, is set using the first trip bolt fixation in described counterbore
It is equipped with some kicker magnets.
Further, described base generally kicker magnet.
A kind of localization method equal for ensureing punching bolt two ends extension elongation, is characterized in that,
Step one, the punching bolt from same length specification, and punching bolt is calculated according to installation requirement stretch out
The length of lower flange (b)；
Gripping mechanism described in step 2, preparation one, described punching bolt is inserted by the lower end of base, promotes a V
Type block moves in the first cavity, until locating convex block slides into suitable scale, rotates screw rod and clamps punching bolt；
Institute is made in bolt hole on step 3, punching bolt insertion lower flange (b) that described gripping mechanism is clamped
State the base of clamping device and lower flange (b) is adjacent to；
Step 4, the nut of rotation punching bolt (c) external part, to being adjacent to upper flange (a), are rotated screw rod, unclamp first
V-block and the second V-block, remove described clamping device, after the nut of rotation punching bolt (c) lower end, by two nut screwing clampings,
Now, punching bolt (c) two ends stretch out flange length identical；
Step 5, repeat step three and step 4, until complete the fastening of whole ring flange.
The invention has the beneficial effects as follows：
The 1st, scale on the basis of base end face is provided with housing, punching bolt is had after base insertion so that the 2nd V
Type block drives the first V-block to move in the first cavity, can install needs according to concrete, when locating convex block is to scale correct position
When rotate screw rod by punching bolt clamp, with described gripping mechanism clamping punching bolt insert lower flange on bolt hole to should
The base of gripping mechanism and lower flange are adjacent to, thus controlling punching bolt to stretch out the length of end face of flange it is ensured that punching bolt two
End extension elongation is equal.
2nd, the first V-block drives the second V-block can accommodate the punching bolt of multiple regulations, and the gripping mechanism of the present invention can
Realize the installation operation of plurality of specifications punching bolt.
3rd, base is arranged to magnetic, for the pipeline of ferrous material, can directly adsorb on lower flange, thus not
Need with handss, it to be assisted, reduce operating procedure；And the use of multiple present invention in extensive installation, can be used
In ensureing the equal positioner of punching bolt two ends extension elongation, punching bolt positioning and nut screwing clamping are separately carried out, many
Individual workmen's separate operation, can effectively improve construction speed in the case of ensureing installation quality.
