Description
Technical Field
The utility model relates to a flange connection bolt dismounting device, and belongs to the technical field of flange connection.
Background
At present, flange structures are often used for equipment die and pipeline connection, and flange connections are generally connected through hexagon bolts and nuts. In the process of loosening the nuts by demolding, the hexagonal bolts can rotate together with the nuts, and after the nuts are loosened, the hexagonal bolts can move towards one side of the nuts in a stringing mode to affect the disassembling efficiency, at the moment, one hand is needed to clamp the hexagonal bolt heads, and the other hand is needed to loosen the nuts.
Disclosure of Invention
The utility model aims to solve the problem that when flange connection equipment is dismounted, bolts can rotate along with nuts to move in series to influence the dismounting efficiency, and provides a flange connection bolt dismounting device.
The utility model aims at realizing the following technical scheme:
the utility model relates to a dismounting device for a flange connection bolt, which comprises a positioning ring and an annular baffle plate, wherein the positioning ring and the annular baffle plate are arranged on one side of the head part of a hexagon bolt at the flange connection part of equipment;
the inner diameter of the positioning ring is matched with the outer diameter of the joint of the equipment flanges, the outer diameter of the positioning ring is matched with the diameter of the circumference of the inscribed circle of each hexagonal bolt head on the connecting flange, and the axial thickness of the positioning ring is matched with the thickness of the hexagonal bolt head;
the inner diameter of the annular baffle is matched with the outer diameter of the joint of the equipment flanges, the outer diameter of the annular baffle is larger than the outer diameter of the positioning ring, and the annular surface of the annular baffle is provided with circumferentially distributed screw passing holes;
screw holes corresponding to the distribution positions of the screw passing holes on the annular baffle are formed in the outer end face of the connecting flange on the side where the head of the hexagonal bolt is located; the positioning rings are sleeved on one side of the heads of the hexagonal bolts at the joint of the equipment flange, and are positioned on the inner sides of the heads of the hexagonal bolts; the annular baffle is connected to one side of the head of the hexagonal bolt at the joint of the flange of the equipment, the positioning ring is fixed to the outer side end face of the connecting flange on one side of the head of the hexagonal bolt through screws, and the positioning ring is limited axially.
The positioning ring and the annular baffle are of a combined piece structure formed by splicing two semicircular sub-pieces, so that the positioning ring is suitable for flange connection equipment with oversized outer end diameter.
Dismantle flange joint, rotate the nut at hexagon bolt afterbody, because the inboard of each hexagon bolt head is received the spacing of holding ring, each hexagon bolt can not rotate along with the rotation of nut, rotates the nut alone and can realize hexagon bolt and nut dismantlement.
Advantageous effects
The flange connection bolt dismounting device is simple in structure and convenient to use, and when the flange connection bolt is dismounted, the bolt cannot rotate and move along with the nut, and the hexagonal bolt and the nut can be dismounted by independently rotating the nut, so that the dismounting efficiency is improved, and the labor intensity of workers is reduced.
Drawings
FIG. 1 is a schematic view of a flange connection bolt dismounting device of the present utility model in use;
FIG. 2 is a left side view of FIG. 1;
in the figure, a 1-positioning ring, a 2-annular baffle, a 3-hexagonal bolt, a 4-nut and a 5-screw.
Detailed Description
The present utility model will be further described with reference to the drawings and examples.
Examples
As shown in fig. 1 and 2, the dismounting device for the flange connection bolt comprises a positioning ring 1 and an annular baffle plate 2, wherein the positioning ring 1 and the annular baffle plate 2 are arranged on one side of the head part of a hexagon bolt 3 at a flange connection part of equipment;
the inner diameter of the positioning ring 1 is matched with the outer diameter of the joint of the equipment flanges, the outer diameter of the positioning ring 1 is matched with the diameter of the circumference of the inscribed circle of the head part of each hexagonal bolt 3 on the connecting flange, and the axial thickness of the positioning ring 1 is matched with the thickness of the head part of the hexagonal bolt 3;
the inner diameter of the annular baffle plate 2 is matched with the outer diameter of the joint of the equipment flanges, the outer diameter of the annular baffle plate 2 is larger than the outer diameter of the positioning ring 1, and the annular surface of the annular baffle plate 2 is provided with circumferentially distributed screw passing holes;
screw holes corresponding to the distribution positions of the screw passing holes on the annular baffle plate 2 are formed in the outer end face of the connecting flange on the side where the head of the hexagon bolt 3 is located; the positioning ring 1 is sleeved on one side of the head of each hexagonal bolt 3 at the equipment flange joint, and the positioning ring 1 is positioned on the inner side of the head of each hexagonal bolt 3; the annular baffle plate 2 is connected to one side of the head of the hexagonal bolt 3 at the joint of the equipment flange, the outer side end face of the connecting flange on one side of the head of the hexagonal bolt 3 is fixed with the locating ring 1 through the screw 5, and the locating ring 1 is limited axially.
Dismantle flange joint, rotate the nut 4 at hexagonal bolt 3 afterbody, because the inboard of each hexagonal bolt 3 head is received spacing of holding ring 1, each hexagonal bolt 3 can not rotate along with the rotation of nut 4, rotates nut 4 alone and can realize that hexagonal bolt 3 and nut 4 dismantle.
