Abstract
The utility model discloses a ring flange clearance expander, including curved extension board, there are first fixed plate and second fixed plate in the both sides of the circular arc of extension board rigid coupling respectively, and first fixed plate and second fixed plate are " L " type, and first fixed plate and second fixed plate are located the homonymy of extension board, and open at the center of extension board has the through -hole, has the bolt through threaded connection in the through -hole, and bolt and first fixed plate are located the both sides of extension board. Use of the present invention ring flange clearance expander, form certain clearance between two ring flanges of messenger that can relax, can conveniently take out and damage the mat and more renew the mat, improved work efficiency greatly.
Description
Technical field
The utility model belongs to extension fixture technical field, is specifically related to a kind of ring flange gap expander.
Background technology
At present, after pipeline installation, two pipe way compact siro spinning technology, when the damage of ring flange pipeline mat need be changed, after being laid down by bolts all on ring flange, mat still tightly can be clamped by ring flange, and general conventional way has ripping bar to be pried open.Use ripping bar to there is very large potential safety hazard, ripping bar inserts two when firmly prizing in the middle of ring flanges, is not plugged or slippage is easy to injure operating personnel or hand-held ripping bar person dodged around as ripping bar.
Utility model content
The purpose of this utility model is to provide a kind of ring flange gap expander, solves the existing problem changing the ring flange pipeline mat difficulty damaged.
The technical scheme that the utility model adopts is, a kind of ring flange gap expander, comprise the support plate of arc, the both sides of the circular arc of support plate are connected with the first fixed head and the second fixed head respectively, first fixed head and the second fixed head are " L " type, and the first fixed head and the second fixed head are positioned at the homonymy of support plate, and the center of support plate has through hole, be threaded connection bolt in through hole, bolt and the first fixed head are positioned at the both sides of support plate.
Feature of the present utility model is also:
The arc of support plate and the consistent of ring flange.
The beneficial effects of the utility model are: use ring flange gap of the present invention expander, can make easily to form certain gap between two ring flanges, conveniently can take out and damage mat and more renew mat, substantially increase operating efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of ring flange gap of the utility model expander structural representation.
In figure, 1. support plate, 2. the first fixed head, 3. the second fixed head, 4. through hole, 5. bolt.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of ring flange gap of the utility model expander, as shown in Figure 1, comprise the support plate 1 of arc, the arc of support plate 1 and the consistent of ring flange, the both sides of the circular arc of support plate 1 are connected with the first fixed head 2 and the second fixed head 3, first fixed head 2 and the second fixed head 3 respectively and are " L " type, first fixed head 2 and the second fixed head 3 are positioned at the homonymy of support plate 1, the center of support plate 1 has through hole 4, has been threaded connection bolt 5 in through hole 4, and bolt 5 and the first fixed head 2 are positioned at the both sides of support plate 1.
During use, by wherein arbitrarily a slice ring flange be stuck in the inside of support plate 1 and the first fixed head 2, second fixed head 3, by the bolt hole on bolt 5 alignment flange dish, bolt hole corresponding for another sheet ring flange is blocked, now, fastening bolt 5, bolt 5 will back down another sheet ring flange, namely form certain gap between two panels ring flange, so just can take out the mat of damage easily and more renew mat simultaneously, greatly increasing operating efficiency.And only need a people to get final product complete operation, also can not cause the possibility that many people mismate is hurted sb.'s feelings.Ring flange gap of the present utility model expander, during for work high above the ground, safety coefficient can improve a lot.
