[0002] In the mechanical equipment such as speed reducer or distribution box, input or output shaft is usually connected by intermediate shaft through flange, during equipment maintenance operation, due to the limitation of site environment, the dismounting operation efficiency of intermediate shaft flange bolt is low, and time is long, and the dismounting of intermediate shaft flange bolt is the problem of maintenance operation.

[0003] Traditional process is after adopting hydraulic wrench to remove nut, bolt is knocked by manpower using sledgehammer, so that bolt is inserted or ejected into the hinge hole of flange, so time-consuming and laborious, and it also causes certain damage to bolt, and causes certain trouble to installation;Especially in the last knocking stage when dismounting, if hammering force is too large, bolt is easy to fly out directly, and it is easy to injure others;For bolt in low position, dismounting personnel also have to lie or stand on toothed joint and knock bolt, to cause certain safety hazard. SUMMARY

[0004] The utility model provides a kind of dismounting frock for large intermediate shaft flange bolt, the dismounting frock of the utility model overcomes the defects of traditional intermediate shaft flange bolt dismounting operation, it is simple in structure, easy to operate, can quickly, conveniently realize the dismounting operation of intermediate shaft flange bolt, improve dismounting operation efficiency, and eliminate safety hazard.

[0005] To solve the above technical problems, the utility model discloses a kind of dismounting frock for large intermediate shaft flange bolt, including top frame and oil cylinder, the top frame includes intermediate connecting rod, mounting seat and two L-shaped rods, the long rod of the two L-shaped rods is set on the both sides of the intermediate connecting rod by screw, the short rod forms bifurcation head, the mounting seat is located at the tail end of the intermediate connecting rod, and the oil cylinder is located at the mounting seat.

[0006] Further, the intermediate connecting rod is provided with a long slot, and the screw is inserted into the long slot and adjusted along the long slot to adjust the distance between the mounting seat and the bifurcation head.

[0007] Further, the dismounting frock further includes an electric pump, and the electric pump is arranged on the mounting seat and drives the oil cylinder.

[0008] The utility model discloses a dismounting tool for large intermediate shaft flange bolt, which comprises a top frame and an oil cylinder, the top frame comprises an intermediate connecting rod, a mounting seat and two L-shaped rods, the long rods of the two L-shaped rods are arranged on the two sides of the intermediate connecting rod through screws, the short rods form a bifurcated head, the mounting seat is arranged at the tail end of the intermediate connecting rod, and the oil cylinder is arranged on the mounting seat. BRIEF DESCRIPTION OF DRAWINGS

[0009] The utility model will be further explained in detail in connection with the drawings and embodiments:

[0010] Figure 1 It is a structural schematic diagram of the dismounting tool for large intermediate shaft flange bolt. CONCRETE EMBODIMENT

[0011] Embodiments such as Figure 1 As shown in the figure, the dismounting tool for large intermediate shaft flange bolt comprises a top frame 1 and an oil cylinder 2, the top frame 1 comprises an intermediate connecting rod 11, a mounting seat 12 and two L-shaped rods 13, the long rods of the two L-shaped rods 13 are arranged on the two sides of the intermediate connecting rod 11 through screws 3, the short rods form a bifurcated head 14, the mounting seat 12 is arranged at the tail end of the intermediate connecting rod 11, and the oil cylinder 2 is arranged on the mounting seat 12.

[0012] Preferably, the intermediate connecting rod 11 is provided with a long groove, the screw 3 penetrates into the long groove and adjusts the distance between the mounting seat 12 and the bifurcated head 14 along the long groove. The adjustment of the distance between the mounting seat and the bifurcated head is used for adapting to the dismounting operation of intermediate shaft flange bolts of different lengths, thereby improving the applicability of the dismounting tool.

[0013] Preferably, the dismounting tool further comprises an electric pump 4, the electric pump 4 is arranged on the mounting seat 12 and drives the oil cylinder 2. The intermediate shaft flange bolt is pushed by the oil cylinder driven by the electric pump, the dismounting operation of the bolt is realized, manpower is saved, and the operation efficiency is improved.

[0014] As Figure 1 As shown in the figure, when the intermediate shaft flange bolt is dismounted, first, the nut 5 is removed by using a hydraulic wrench, then the bifurcated head 14 of the tool is abutted to the back surface of the flange 6 and clamped at the position of the screw cap of the bolt 7, the oil cylinder 2 is abutted to the threaded end of the bolt 7, the oil cylinder 2 is started to push out the bolt 7 from the hinge hole of the flange 6, and the bolt can be conveniently removed.

[0015] In the middle shaft flange bolt installation, the split head 14 of the tool is abutted to the front of the flange 6, the hinge hole of the flange 6 is located between the split head 14, the threaded end of the bolt 7 is aligned with the hinge hole of the flange 6, the oil cylinder 2 is against the nut of the bolt 7, and the bolt 7 is driven into the hinge hole of the flange 6 by starting the oil cylinder 2, so that the bolt installation can be conveniently realized.

[0016] By using the tool, the lifting function of the oil cylinder can quickly, smoothly and safely drive the bolt out of or push into the hinge hole of the flange, and the bolt disassembly operation can adapt to the narrow space on site, avoiding many safety hazards of manual knocking of the bolt for disassembly in the past, improving the operation efficiency, reducing the manual input, reducing the safety risk in the operation process, and ensuring the controlled operation quality.
