Description of the drawings:
fig. 1 is a schematic view of the overall structure of the present invention.
The device comprises a fixed rod 1, a clamping groove 1.1, a supporting mechanism 2, a supporting arm 3, a sleeve 4, a blind hole 4.1, a jacking bolt 5, a wedge-shaped tool bit 6, a guide rod 6.1, a sliding sleeve 7 and a locking bolt 8.
The specific implementation mode is as follows:
in the description of the present invention, it should be noted that, as the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, but does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" as appearing herein are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, a flange jacking device comprises a fixed rod 1 and a jacking mechanism 2, wherein the fixed rod 1 is provided with two symmetrically arranged jacking mechanisms 2 in a sliding manner, each jacking mechanism 2 comprises a supporting arm 3, a sleeve 4, a jacking bolt 5 and a wedge-shaped tool bit 6, one end of each supporting arm 3 is arranged along the fixed rod 1 in a sliding manner, and a locking bolt 8 movably abutted against the fixed rod 1 is screwed on each supporting arm 3; a sleeve 4 arranged in parallel with the fixed rod 1 is fixed at the other end of the supporting arm 3, a wedge-shaped tool bit 6 vertically arranged relative to the fixed rod 1 is inserted on the opposite end surfaces of the two sleeves 4 in a sliding manner, and a jacking bolt 5 with the top end rotationally connected with the wedge-shaped tool bit 6 is screwed in the sleeve 4; two guide rods 6.1 are evenly distributed on the connecting end face of the wedge-shaped tool bit 6 and the jacking bolt 5, a blind hole 4.1 is formed in the position, corresponding to the guide rod 6.1, of the sleeve 4, and the guide rod 6.1 is slidably arranged in the blind hole 4.1. When the wedge tool bit 6 on two 3 one end sleeves 4 of support arm supports the gap of the flange joint that corresponds respectively, guide bar 6.1 and flange all can carry on spacingly to the radial rotation of wedge tool bit 6, during precession corresponding jacking bolt 5, axial removal only takes place for wedge tool bit 6, and then drive wedge tool bit 6 and prop the top to the gap of flange joint, change the flange pad operation after opening certain aperture with the gap of flange joint, change the operation and accomplish the back, the precession jacking bolt 5, it resets to drive wedge tool bit 6, convenient and fast when this structure is operated, labour saving and time saving, only need precession jacking bolt 5 can accomplish the separation to the flange joint after the gap that wedge tool bit 6 supported the flange joint.
