Three mounting circular holes 9 are evenly provided on the top surface of the supporting tooling 8, and a hydraulic wrench 11 is installed inside each mounting circular hole 9. The inside of the middle mounting circular hole 9 can be replaceably installed with a supporting tooling 2, that is, three hydraulic wrenches 11 are installed in the supporting tooling 8, and a pneumatic wrench 14 is installed in the supporting tooling 2;

[0083] The hydraulic wrench 11 is used for loosening the bolts with a large torque during the bolt removal process and for the final torque setting operation when reinstalling the bolts;

[0084] The triple assembly has high disassembly and assembly efficiency, and is driven by the wrench lifting drive assembly to rise and fall in the vertical direction, so that the wrench can be used to disassemble and assemble bolts at different heights, and can be rotated in the horizontal direction to facilitate alignment with the bolt disassembly and assembly position, so as to disassemble and assemble bolts in different positions, thereby improving applicability. The machine is used for disassembly and assembly of bolts, which has low labor intensity, improves disassembly and assembly efficiency, and reduces safety risks.

[0085] See Figure 1 As shown, the wrench lifting guide assembly includes two parallel supporting plates 2, and a telescopic guide module 3 is fixedly installed on the inner wall surface of each supporting plate 2. A diagonal support bracket 4 is installed on the top inner wall surface of each telescopic guide module 3. The upper surfaces of the two diagonal support brackets 4 are installed with a mounting plate 5. The bottom surface of the mounting plate 5 is connected to the pushing end of the servo electric cylinder 1, and the top surface of the mounting plate 5 is rotatably set to one end of the supporting folding arm joint 6. The servo electric cylinder 1 pushes the mounting plate 5 and the supporting folding arm joint 6 to move upward, driving the diagonal support bracket 4 and the telescopic guide module 3 to telescopically slide on the supporting plate 2, thereby realizing the guiding and torque bearing functions of the wrench lifting action within a limited total height.

[0086] See Figure 1As shown, the supporting fixture 2 includes a U-shaped steel plate 13, and a circular steel shaft 15 is provided on one side of the U-shaped steel plate 13 for use with a central mounting circular hole 9, and a pneumatic wrench 14 is installed inside the U-shaped steel plate 13. The upper surface of the supporting fixture 1 8 is provided with a locking hole 10 communicating with the mounting circular hole 9. Three hydraulic wrenches 11 are installed in the mounting circular hole 9 in the supporting fixture 1 8, and bolts are installed in the locking holes 10 to fix the hydraulic wrenches 11; when disassembling and assembling the bolts, the supporting fixture 1 8 bears the counter torque of the disassembly and assembly of the three bolts, thereby realizing the simultaneous disassembly and assembly of the three bolts.

[0087] See Figure 1 and Figure 3 As shown, an operating handle 12 is installed on one side of the bottom of the supporting tooling 8, and a fixing clamp 16 is installed on the other side of the bottom of the supporting tooling 8. The other end of the supporting folding arm joint 6 is rotatably mounted with a fixing rod 7, and the fixing rod 7 is fixed to the bottom surface of the supporting tooling 8. A lifting button is embedded in the operating handle 12;

[0088] The input end of each hydraulic wrench 11 is connected to a hydraulic oil pipe 17, and the input end of the pneumatic wrench 14 is connected to an air pipe 18. The outer sides of the hydraulic oil pipe 17 and the air pipe 18 are provided with an annular convex portion 19. The fixing clamp 16 is provided with three arc-shaped portions 20. The diameter of the arc-shaped portion 20 is smaller than the diameter of the annular convex portion 19, and the arc-shaped portion 20 is in contact with the annular convex portion 19. When in use, the hydraulic wrench 11 and the pneumatic wrench 14 are installed in the supporting fixture 8, and each hydraulic wrench 11 is connected to the corresponding hydraulic oil pipe 17. The hydraulic oil pipe 17 connected to the hydraulic wrench 11 and the air pipe 18 connected to the pneumatic wrench 14 are fitted close to the surface of the supporting tooling 8, and then the fixing clamp 16 is installed. After the arc portion 20 on the fixing clamp 16 is fitted into contact with the annular protrusion 19, it is tightened with bolts to fix the hydraulic oil pipe 17 and the air pipe 18 separately to avoid entanglement. The pneumatic wrench 14 and the hydraulic wrench 11 are moved and raised to the bolt position through the operating handle 12 on the supporting tooling 8 to perform quick disassembly and assembly of the bolts.

[0089] When removing the bolts, three hydraulic wrenches 11 are installed in the supporting fixture 1 8, and the supporting fixture 1 8 bears the counter torque of the three bolts, thereby realizing the simultaneous disassembly and assembly of the three bolts. When the bolts are loosened, the pneumatic wrench 14 is installed in the supporting fixture 2, and the supporting fixture 2 with the pneumatic wrench 14 is installed in the middle mounting circular hole 9. The bolts are disassembled by the high speed of the pneumatic wrench 14, and the disassembly and assembly efficiency is high. The wrench is lifted and lowered in the vertical direction under the drive of the wrench lifting drive assembly, so that the wrench can be used for bolt disassembly and assembly at different heights, and can be rotated in the horizontal direction, which is convenient for aligning the bolt disassembly and assembly position to disassemble and assemble bolts at different positions.

[0090] When reinstalling the bolts, the bolts are tightened at a high speed using the pneumatic wrench 14, and then the supporting tooling 2 in the middle mounting hole 9 is replaced with a hydraulic wrench 11. The final torque setting operation of the bolts is performed using the triple hydraulic wrench, which improves applicability, reduces labor intensity, improves disassembly and assembly efficiency, and reduces safety risks.

[0091] Each hydraulic wrench 11 is connected to a corresponding hydraulic oil pipe 17. The hydraulic oil pipe 17 connected to the hydraulic wrench 11 and the air pipe 18 connected to the pneumatic wrench 14 are attached to the surface of the supporting tool 8. Then, the fixing clamp 16 is installed. After the arc portion 20 on the fixing clamp 16 is attached to the annular protrusion 19, it is tightened with bolts to separate the hydraulic oil pipe 17 and the air pipe 18 to avoid entanglement.

[0092] Referring to the second embodiment, the second supporting fixture is adjustably mounted on one side of the first supporting fixture. When a high torque of the hydraulic wrench is required, the second supporting fixture is adjusted backward so that the pneumatic wrench 14 is located behind the hydraulic wrench 11. When a high speed of the pneumatic wrench is required, the second supporting fixture is adjusted forward so that the pneumatic wrench 14 is flush with the hydraulic wrench 11 or located in front of the hydraulic wrench 11. The remaining features are the same as those of the first embodiment.

[0093] On the basis of the second embodiment, in this embodiment, the arc-shaped portions 20 on the fixing clamps 16 are arranged in four groups, and three groups of hydraulic oil pipes 17 and one group of air pipes 18 are fixed at the same time.
