Description

simple flange separation tool

Technical Field

the utility model belongs to the technical field of the flange mounting of pipeline valve door, maintenance, concretely relates to simple and easy flange separation instrument.

Background

The Flange (Flange) is also called a Flange plate or Flange. Flanges are parts that interconnect pipes to pipes and to valves, and are attached to the ends of the pipes. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flanges are sealed with gaskets. Has wide application in production and life.

The flange bolts can be directly taken down by using the flange-connected equipment during maintenance, two flanges are separated, and damaged parts such as a liner are maintained or replaced. The pipeline is corroded, expands with heat and contracts with cold, and sags, so that the gap between flanges is reduced or the flanges are seized, and the separation is difficult. The time spent for separating the flanges in the maintenance process is more.

The separation flange mainly adopts artifical sled or hydraulic separation in the current maintenance process. The manual use of crowbars for separation is only suitable for occasions with small size and low pipeline tension, and cannot deal with large-diameter pipelines. The hydraulic separator has large moment and can separate large-size flanges. But the price is higher, and equipment size is great, does not open in narrow and small space, and the daily maintenance is complicated.

The utility model provides a simple and easy flange separation instrument, includes two dead levers, a connecting rod and jackscrew, two the dead lever symmetry is installed the last of connecting rod, the dead lever passes through bolted connection with the connecting rod, the jackscrew transversely run through in the connecting rod, just the jackscrew is located the inboard of dead lever, the wedge is installed through the universal joint to the one end of jackscrew.

Preferably, the fixing rod is L-shaped, the longer end of the fixing rod is connected with the connecting rod, and the shorter end of the fixing rod is close to the wedge-shaped block.

Preferably, the fixing rod is provided with a plurality of first screw holes matched with the bolts, the first screw holes are distributed on the fixing rod at equal intervals, the connecting rod is provided with a plurality of second screw holes matched with the bolts, and the second screw holes are distributed at the two ends of the connecting rod at equal intervals.

Preferably, one side of the wedge-shaped block, which is far away from the jackscrew, is an inclined plane.

Preferably, one end of the jackscrew, which is far away from the fixing rod, is square or hexagonal.

Compared with the prior art, the beneficial effects of the utility model are that:

This flange separation instrument passes through fixed pipe to be fixed on the flange, extrudees into the flange gap with the wedge through the jackscrew, separates two flanges, can effectively save manpower, material resources, greatly reduced the cost of overhauing, and the position of dead lever can be adjusted as required, is applicable to the maintenance work of the flange of equidimension not.

Detailed Description

The present invention will be further described with reference to the following examples.

The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. The condition in the embodiment can be further adjusted according to concrete condition the utility model discloses a it is right under the design prerequisite the utility model discloses a simple improvement of method all belongs to the utility model discloses the scope of claiming.

Please refer to fig. 1-2, the utility model provides a simple and easy flange separation tool, including two dead levers 1, a connecting rod 2 and a jackscrew 3, two dead levers 1 symmetry are installed on connecting rod 2, and dead lever 1 passes through bolt 5 with connecting rod 2 to be connected, and jackscrew 3 transversely runs through in connecting rod 2, and jackscrew 3 is located the inboard of dead lever 1, and wedge 4 is installed through the universal joint to the one end of jackscrew 3.

After the fixing bolts of the connecting flanges are loosened, the two fixing rods 1 are clamped on the two flanges respectively, the jackscrews 3 are rotated to enable the jackscrews 3 to be close to the flanges, and therefore the wedge-shaped blocks 4 are extruded into the gaps of the flanges, and the flanges are separated.

Specifically, the fixing rod 1 is L-shaped, the longer end of the fixing rod 1 is connected with the connecting rod 2, and the shorter end of the fixing rod 1 is close to the wedge-shaped block 4;

when the tool is used, the fixing rod 1 is directly sleeved into the bolt hole of the flange in a shorter way so as to be fixed on the flange, and the tool is more convenient to use.

Specifically, a plurality of first screw holes 6 matched with the bolts 5 are formed in the fixed rod 1, the plurality of first screw holes 6 are distributed on the fixed rod 1 at equal intervals, a plurality of second screw holes 7 matched with the bolts 5 are formed in the connecting rod 2, and the plurality of second screw holes 7 are distributed at two ends of the connecting rod 2 at equal intervals;

Through set up the first screw 6 that a plurality of equidistance was arranged on dead lever 1, set up the second screw 7 that a plurality of equidistance was arranged at the both ends of connecting rod 2 to can adjust the distance between two dead levers 1 as required, can adjust the distance between connecting rod 2 and the flange as required simultaneously, make this instrument be applicable to not the flange maintenance of equidimension.

specifically, one side of the wedge-shaped block 4, which is far away from the jackscrew 3, is an inclined plane; one side is inclined, the other side is horizontal, so that resistance is reduced, the wedge block 4 can be pushed into a gap of the flange, and the two flanges are loosened.

Specifically, one end of the jackscrew 3, which is far away from the fixing rod 1, is square or hexagonal; the square or hexagonal that has the edges and corners is adopted to the one end of jackscrew 3 and is formed, makes things convenient for the installation of other instruments, facilitates the use of tools.

The utility model discloses a theory of operation and use flow:

during the use, according to the size of two flanges, make the bolt hole of 1 short one end insertion flange of dead lever to ensure that wedge 4 can normally contact with the flange, fix dead lever 1 on connecting rod 2 through bolt 5, then rotate jackscrew 3 again, under the effect of universal joint, wedge 4 remains motionless, makes jackscrew 3 remove to the one end that is close to the flange, thereby in the gap of going into the flange with wedge 4 top, and then with two flange separations.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
