Further, the utility model relates to a flange bolt dismounting device, wherein, the internal thread of first screw hole is the right-handed thread, the internal thread of second screw hole is left-handed thread.
Further, the utility model relates to a flange bolt dismounting device, wherein, the one end of first jackscrew and second jackscrew is equipped with the hexagon head respectively.
Further, the utility model relates to a flange bolt dismounting device, wherein, the other end of first jackscrew and second jackscrew is equipped with spacing dish respectively.
Further, the utility model relates to a flange bolt dismounting device, wherein, the fixed block is equipped with the holding tank with the position that spacing dish corresponds.
The utility model relates to a flange bolt dismounting device compares with prior art, has following advantage: the utility model discloses a set up fixed block, first jackscrew and second jackscrew, set up notch cuttype U type draw-in groove at the middle part of fixed block, the both sides position correspondence that is in notch cuttype U type draw-in groove at the fixed block sets up first screw hole and second screw hole, makes first jackscrew and second jackscrew correspond and adorn soon in the first screw hole and the second screw hole of fixed block. Therefore, the flange bolt dismounting device with simple structure, low cost, convenient operation and strong practicability is formed. In practical application, at first detach the nut of flange bolt one end, with the nut of the flange bolt other end pine soon, and will the utility model discloses a fixed block passes through notch cuttype U type draw-in groove card between the nut of pine soon and flange dish, then first jackscrew of synchronous revolution and second jackscrew can be pulled out flange bolt from the flange connecting hole through first jackscrew and second jackscrew roof pressure ring flange to realize dismantling flange bolt's technical purpose. Compared with the prior art, the utility model discloses not only easy and simple to handle has improved work efficiency, and can avoid the problem that the flange bolt damaged.
The following describes a flange bolt dismounting device according to the present invention in further detail with reference to the embodiments shown in the drawings.

Detailed Description
It should be noted that, in the present invention, the terms of upper, lower, left, right, front, rear, etc. are only described according to the accompanying drawings, so as to facilitate understanding, and are not intended to limit the technical solution and the scope of the present invention.
As shown in fig. 1 to 5, the present invention relates to a flange bolt dismounting device, which comprises a fixing block 1, a first jackscrew 2 and a second jackscrew 3. The middle part of the fixing block 1 is provided with a step-shaped U-shaped clamping groove 11, and the positions of the two sides of the fixing block 1, which are positioned in the step-shaped U-shaped clamping groove 11, are correspondingly provided with a first threaded hole and a second threaded hole, so that the first jackscrew 2 and the second jackscrew 3 are correspondingly and rotatably arranged in the first threaded hole and the second threaded hole of the fixing block 1. Through the structure, the flange bolt dismounting device with simple structure, low cost, convenient operation and strong practicability is formed. In practical application, at first detach the nut of 6 one ends of flange bolt, with the nut of the 6 other ends of flange bolt soon loose, and will the utility model discloses a fixed block 1 passes through notch cuttype U type draw-in groove 11 card between the nut and the flange dish of soon loosening, then synchronous rotation first jackscrew 2 and second jackscrew 3 can pull out flange bolt 6 from the flange connecting hole through first jackscrew 2 and 3 roof pressure ring flange 7 of second jackscrew to realize dismantling the technical purpose of flange bolt 6. Compared with the prior art, the utility model discloses not only easy and simple to handle has improved work efficiency, and can avoid the problem that the flange bolt damaged.
As an optimized solution, in the present embodiment, the internal thread of the first threaded hole is a right-handed thread, and the internal thread of the second threaded hole is a left-handed thread. The structure can avoid mutual influence when the first jackscrew 2 and the second jackscrew 3 are synchronously rotated, and improves the convenience and the working efficiency of operation. In order to facilitate the rotation of the first jackscrew 2 and the second jackscrew 3, the hexagonal heads 4 are respectively arranged at one ends of the first jackscrew 2 and the second jackscrew 3 so as to be connected with a wrench, and the wrench can adopt an ordinary wrench and a ratchet wrench. Meanwhile, the other ends of the first jackscrew 2 and the second jackscrew 3 are respectively provided with a limiting disc 5. Spacing dish 5 on the one hand can restrict first jackscrew 2 and second jackscrew 3 and the separation of fixed block 1, has avoided the problem that spare part loses, and another mode can increase the area of contact of first jackscrew 2 and second jackscrew 3 with ring flange 7, has improved the stability of operation. In addition, this embodiment has set up holding tank 12 in the fixed block 1 and the position that spacing dish 5 corresponds to holding spacing dish 5, improved the convenience of installation fixed block 1, and can reduce thickness and occupation space.
The above embodiments are only descriptions of the preferred embodiments of the present invention, and are not intended to limit the scope of the claimed invention, and various modifications made by those skilled in the art according to the present invention should fall within the scope of the present invention defined by the appended claims without departing from the design concept of the present invention.
