Description
Technical field
A kind of a kind of the present invention relates to flange separating tool technical field, more particularly to flange hydraulic pressure separating instrument.
Background technology
It is most in the pipeline and pressure vessel and equipment of the industries such as oil, chemical industry, generating, shipbuilding, iron and steel using flange connection
A kind of universal mechanical connection manner.Due to these bad borders residing for industry device it is more severe, the phenomenon such as high temperature, high salt, humidity
Seriously, all there is different degrees of corrosion condition in equipment, and pipeline and tankage repair time are long, flange connection surface rust
Erosion situation is particularly acute, big and live in petrochemical enterprise so as to cause its flange in maintenance process to disassemble difficulty
What is processed is all petroleum gas, is all inflammable and explosive dangerous materials, and this just more increases the difficulty that flange is disassembled.It is how safe
Simply and efficiently splitting flange becomes the key factor for affecting maintenance of equipment progress, also becomes field maintenance staff's
A great problem.
To realize that flange splits in this case, typically there are two methods：
One is come separate pipeline or the adpting flange of container, if do so not only consumes with the traditional method of iron hammer and chisel
Take substantial amounts of manpower and materials, waste the substantial amounts of quality time, this will directly affect maintenance of equipment progress, affect economic effect
Benefit.
Two is that this method is if in workshop or other safety separating adpting flange using the method expanded with heat and contract with cold
Region is effective method.But in petrochemical enterprise, in-situ processing is all petroleum gas, all it is inflammable easy
There is the danger of height in quick-fried dangerous materials, the method expanded with heat and contract with cold, be worthless in this case.
Three are separated adpting flange with suspender or loop wheel machine, and requirement will have larger space convenient first in this way
Loop wheel machine is parked and operation, and flange is an entirety with the pipeline or container that are connected, in suspender or loop wheel machine operation, power
Amount control is uneven to be easy for device damage gently then being increased workload, heavy then cause equipment unrepairable, its Jing
Ji loss is inestimable.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of flange hydraulic pressure separating instrument, this body of tool
Little, the simple structure of product, it is easy to use, it is explosion-proof, can be made using current material, its structural member size is according to split flange chi
Adpting flange safely and efficiently can be separated by very little decision, this instrument, particular for that it is larger and it is long neglected and in disrepair cause connect
The serious corrosion of acting flange situation together.
The technical solution adopted in the present invention is：A kind of flange hydraulic pressure separating instrument, including supporting steel frame, in supporting steel frame
Between have jack fixing bolt and jack fixed plate, it is very heavy with jack fixed plate fixed hydraulic by jack fixing bolt
Top, the pars contractilis connection wedge head of hydraulic jack, the both sides of supporting steel frame further respectively have stay-bolt by locking nut, draw
The lower end of bar bolt is connected with location-plate, be equipped with connecting rod between two location-plates, and connecting rod is respectively arranged at two ends with lock pin.
Used as a kind of preferred technical scheme of the present invention, described supporting steel frame is led to by two pieces of iron and steel blocks and two steel rings
Cross two bolt connections to be made, one gap more than stay-bolt external diameter of its intermediate formation.
Used as a kind of preferred technical scheme of the present invention, described location-plate is sector, and bottom is according to pipe shape system
Make camber or flat mouth shape, both sides offer two holes more than connecting rod external diameter, upside and stay-bolt according to flange screw
Junction is two square iron blocks of welding, and stay-bolt is connected between two square iron blocks of location-plate by nut.
Used as a kind of preferred technical scheme of the present invention, round end one end of described wedge head is flexible with hydraulic jack
Position size is identical, and round end one end is entangled using an iron ring so as to which, with hydraulic jack seamless combination, the side of wedge head is welded
There is an earrings.
As a kind of preferred technical scheme of the present invention, the length of described connecting rod and the length phase of supporting steel frame
Together, connecting rod two ends are equipped with the pin-and-hole of grafting lock pin.
As a kind of preferred technical scheme of the present invention, described jack fixed plate size and hydraulic jack
Top end face it is consistent, be drilled with big two little three screws in jack fixed plate, by bolt and little screw by hydraulic jack
Tighten together with jack fixed plate, hydraulic jack is fixed on big screw by supporting steel frame by jack fixing bolt
On.
Used as a kind of preferred technical scheme of the present invention, described jack fixing bolt and stay-bolt pass through spiral shell
It is female to be fixed in the intermediate gap of supporting steel frame with pad.
Compared with prior art, the invention has the beneficial effects as follows：Instrument small volume, simple structure are easy to use, explosion-proof,
Can be made using current material, its structural member size is determined according to split flange size.This instrument can be safely and efficiently
Adpting flange is separated, particular for that situation for causing the serious corrosion of adpting flange together larger and long neglected and in disrepair.
