Description
Technical field
The utility model is related to a kind of auxiliary tool, especially a kind of online flange device for spreading.
Background technology
With the continuous development of petrochemical industry, low medium-voltage equipment, pipeline increasingly increase, and flange maintenance amount increasingly increases.If
Standby overhaul must be completed at 1 month or so, and in equipment rebuilding, the dismounting operation of flange is more, and hydraulic method can be used in high pressure flange
Blue dilator struts, but hydraulic flange dilator resource is nervous and One-Shift Costs are higher, and owner, which removes, makes high-pressure system flange
With can be confirmed outside expense, remaining not confirms, because construction cost is too high.Construction site is badly in need of inexpensive, easy to operate at present
Auxiliary tool solve the problems, such as that the less big online mesolow flange of clamping force struts.
Invention content
The utility model provides a kind of online flange device for spreading to solve technical problem present in known technology, should
Installation cost is low, it is easy to operate, can rapidly strut online mesolow flange.
The utility model is adopted the technical scheme that solve technical problem present in known technology：A kind of on-line method
Blue device for spreading, including horizontally disposed balancing pole are set with there are one hanger at the both ends of the balancing pole, in the extension
It is equipped with anchor fluke on the inside of the lower end of arm, the mandril being threadedly coupled with it, the mandril and institute are equipped at the middle part of the balancing pole
It states that balancing pole is vertical, crank is equipped in the upper end of the balancing pole, wedge type top is equipped in the lower end of the balancing pole, it is described
Wedge type top axial restraint is sleeved on the lower end of the balancing pole with circumferentially rotating.
It is equipped with annular groove in the lower end of the balancing pole, screw, the screw are connected on wedge type top
Lower end be inserted into the annular groove.
The utility model has the advantages and positive effects of：It is fixed by using balancing pole and hanger, using mandril band
Dynamic wedge type comes directly towards the structure moved down, can quickly strut online mesolow flange, and a people can be operated, and work efficiency is high,
Economic effect is good；Wedge type top acts on flange periphery, will not injure flange sealing surface, be conducive to flange protection；With use
Crowbar struts flange sealing surface and compares, and will not skid, and will not injure operating personnel, improves the safety of operation；Hanger position
It is adjustable, the flange for being applicable in different-thickness is enabled the device to, it is applied widely；And the utility model also has system easy to process
Work, the features such as install convenient, occupying little space, is esy to use, safe and reliable, have good generalization.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1, crank；2, mandril；3, screw；4, wedge type comes directly towards；5, anchor fluke；6, annular groove；7, hanger；8, it balances
Bar.
Specific implementation mode
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing：
Referring to Fig. 1, a kind of online flange device for spreading, including horizontally disposed balancing pole 8, in the balancing pole 8
Both ends are set with there are one hanger 7, anchor fluke 5 are equipped on the inside of the lower end of the hanger 7, at the middle part of the balancing pole 8
Equipped with the mandril 2 being threadedly coupled with it, the mandril 2 is vertical with the balancing pole 8, is equipped in the upper end of the balancing pole 8
Crank 1 is equipped with wedge type in the lower end of the balancing pole 8 and comes directly towards 4, and the wedge type comes directly towards 4 axial restraints and is sleeved on circumferentially rotating
On the lower end of the balancing pole 2.
In the present embodiment, it is equipped with annular groove 6 in the lower end of the balancing pole 8, is connected on wedge type top 4
There are screw 3, the lower end of the screw 3 to be inserted into the annular groove 6, so that the wedge type is come directly towards 4 axial restraints and circumferentially turn
It is sleeved on dynamicly on the lower end of the balancing pole 2.
Before use, unclamping the connection bolt of flange, and extract a connection bolt out.In use, two on adjustment balancing pole 8
The position of hanger 7, and anchor fluke 5 is inserted into the bolt hole of flange, crank 1 is then rotated, mandril 2 is driven to rotate, mandril 2 drives
Wedge type top 4 moves down, to realize strutting for flange.
Although the preferred embodiment of the utility model is described above in conjunction with attached drawing, the utility model is not
It is confined to above-mentioned specific implementation mode, the above mentioned embodiment is only schematical, is not restrictive, ability
The those of ordinary skill in domain is not departing from the utility model aims and claimed under the enlightenment of the utility model
In the case of range, many forms can also be made, these are belonged within the scope of protection of the utility model.
