Description
Technical Field
The utility model relates to the field is dismantled in the tube coupling, a flange struts device specifically says so.
Background
The pipeline connection means that the prefabricated pipe sections are connected into a complete system according to the requirements of design drawings. In various installation pipelines, due to the certain tension of the installed pipelines, the installation and the removal of various elements connected between the pipe ends of the pipelines are extremely difficult. In the case of pipe ends flanged, flange spreaders are often used to accomplish these operations.
The flange spreader used at present is complex in structure and complex in operation, and can only operate the flange with a single specification due to different thicknesses of the flange, so that the working efficiency is low, and unnecessary resource waste is caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a modified flange struts device can solve the technical problem that the above-mentioned exists.
For the aforesaid problem that solves the utility model adopts the following technical scheme: an improved flange spreader device includes a first operating module and a second operating module; one side of the U-shaped structure of the first operation module is provided with an internal thread hole, a hexagon bolt is arranged in the internal thread hole, the center of a bulge on the back of the U-shaped structure is provided with the internal thread hole, a screw rod is arranged in the internal thread hole, and one end of the screw rod is of a hexagonal structure; one side of the U-shaped structure of the second operation module is provided with an internal thread hole, a hexagon bolt is arranged in the internal thread hole, a circular sinking platform is arranged at the center of the bulge on the back of the U-shaped structure, and the circular sinking platform is coaxial with the screw rod.
The operation process in the technical scheme is as follows: the first operating module and the second operating module are respectively installed on two pipe end flanges, the U-shaped structure is provided with a hexagon head bolt end outside the flanges, and the operation modules are firmly installed by adjusting the hexagon head bolt. And adjusting a screw rod on the back surface of the U-shaped structure of the first operation module to be matched with a circular sinking platform on the back surface of the U-shaped structure of the second operation module, and screwing the screw rod to expand the flange to a required position.
The utility model provides a device has following advantage compared in current flange spreader: simple structure, easy operation, portable, safe and reliable in the operation process has mentioned work efficiency greatly. The hexagonal head bolt in the U-shaped structure can meet clamping requirements of flanges of different specifications, the requirement that the flanges of different specifications need to be provided with one set is eliminated, and cost is saved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
An improved flange opening device is shown in figure 1, wherein one side of a U-shaped structure of a first operation module 3 is provided with an internal threaded hole 2-2, a hexagon bolt 4 matched with the internal threaded hole is arranged in the internal threaded hole, the back of the U-shaped structure is provided with an internal threaded hole 2-2, and a screw 5 matched with the internal threaded hole is arranged in the internal threaded hole. The second operation module is the same as the first operation module in shape, one side of the U-shaped structure of the second operation module is provided with an internal threaded hole 2-2, a hexagonal head bolt 4 matched with the internal threaded hole is arranged in the hole, and the back of the U-shaped structure is provided with a circular sinking platform 2-1.
The round sinking platform 2-1 protruding from the back of the U-shaped structure of the second operation module 2 is coaxial with the internal threaded hole 2-2 protruding from the back of the U-shaped structure of the first operation module 3.
In use, as shown in fig. 1, the first operating module 3 and the second operating module 2 are respectively clamped on the pipeline flange 1, and one end of the operating module with the hexagon head bolt 4 in the U-shaped structure faces the outer side of the flange 1, so that the operating module can be adjusted according to different flange thicknesses and locked on the flange.
Furthermore, the screw 5 is screwed by adjusting the screw 5 to be matched with the circular sinking platform 2-1 protruding from the back of the U-shaped structure of the second operating module 2, so that the distance required by the opening of the flange is reached.
Finally, it is noted that the above examples are only intended to illustrate the technical solutions of the present invention and not to limit the same, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
