Description

Technical Field

[0001] The invention relates to the technical field related to flange separators, and in particular to a flange separator used for pipeline maintenance. Background Art

[0002] Flange, derived from the English word Flange, is also called flange flange or flange. Its basic meaning refers to a protruding structure on an object, or an object with a protruding structure, such as flange bolts, flange shafts, etc. Since flange structures are often used for connections between shafts, between pipe ends, or between equipment, the flange usually refers to a part or structure used for connection in the mechanical field, such as pipe flanges and reducer flanges.

[0003] The existing flange separators need to carry a lot of tools to remove the screws of the flanges when in use, and the flanges are prone to rust and stick together after long-term use, making them difficult to separate, requiring workers to spend a lot of time to disassemble. Summary of the invention

[0010] Preferably, the clamping mechanism is provided with springs which are equidistantly arranged longitudinally, and the number of the springs is 4 in total.

[0011] Preferably, the separator on the left side of the rotating seat is triangular in shape, and the separators are arranged in parallel and symmetrically.

[0012] Compared with the prior art, the beneficial effects of the present invention are: before use, the clamping mechanism is placed on the screw, the fixing block will shrink inward according to the size of the screw, and then the shaft rod is driven by the rotation of the motor, and the shaft rod drives the clamping mechanism to rotate, so that the clamping mechanism twists off the screw without using other tools. When the flange needs to be separated, the separator is inserted into the flange gap, and then the hydraulic rod is extended by the oil cylinder to make the separator open on the rotating seat, thereby separating the flange, and the fixing screw hole and the fixing thread are convenient for the staff to disassemble the clamping mechanism and the oil cylinder.
