Problems solved by technology

[0003] First, the calibration workload is heavy, and the operators are often physically exhausted
[0004] Second, the positions that can be corrected by hammering are limited, and some positions cannot be calibrated, resulting in the fact that after the bending plate is calibrated, the size meets the requirements, but the shape accuracy is not good.
[0005] Third, the efficiency of manual hammering correction is very low, and the quality of correction is also poor, which is not conducive to the realization of standard operation and assembly line operation

[0038] refer to figure 1 with figure 2 .

[0039] This embodiment includes a platform 4, a lifting and turning machine 2 and a hammering device 3; wherein, the lifting and turning machine 2 is used to clamp the bent plate of the crane arm, and realize the lifting and turning of the bent plate; the hammering device 3 is slidably connected The first guide rail 8 is used to hammer the bent plate of the boom of the crane; the platform 4 is a platform with a detection reference, which is used to provide a calibration reference for the hammering device 3 .

[0040] In addition, it should be noted that the liftable turning machine 2 may not be connected with the platform 4 . If the two are connected together, the platform where the liftable turning machine 2 is placed must have a step surface to ensure that when the curved plate is lowered by the lifting turning machine 2, the chain of the lifting turning machine 2 can fall below the platform 4, ensuring The bent plate can be pla...

[0043] refer to image 3 with Figure 4 .

[0044] The special machine for correcting the bent plate of the crane arm in this embodiment includes: this embodiment includes a platform 4, a liftable turning machine 2 and a hammering device 3; Lifting and flipping of the board; the hammering device 3 is slidably connected to the first guide rail 8 for hammering the bent plate of the crane arm;

[0045] Moreover, different from the first embodiment, the calibration plane also includes a first detection device 9A and a second detection device 9B, and these two detection devices are slidably connected to the platform 4 through the second guide rail 11 .

[0046] Since the platform in this embodiment is a platform with a detection reference, and there are two detection devices connected to the platform, the height and straightness of the bent plate can be automatically detected by the detection device, avoiding the possibility of being caused by manual experience. The defects of l...

Abstract

The invention discloses a special machine for correcting bend plates of crane booms and a correcting method. The special machine for correcting bend plates of crane booms comprises a platform, a lifting turnover device and a hammering device, wherein the lifting turnover device is used for lifting and turning the bend plates, the hammering device is slidably connected to a first guide rail and used for hammering to correct the bend plates of the crane booms, the platform serves as a measurement reference and is used for measuring the height, width, linearity and shape precision of the bend plates and providing foundation for correction. The bend plates can be lifted and turned to the proper positions by the lifting turnover device and then are hammered and corrected by the manipulator type hammering device. Compared with the manner of manual hammering correction in the prior art, the correcting method has the advantages of improving work efficiency and correcting quality and facilitating realization of standard operation and streamline production.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a special plane for correcting a bent plate of a crane arm and a correction method. Background technique [0002] At present, when correcting the bending plate of the crane arm, the bending plate is generally adjusted to the platform, and the hammering correction is performed manually. The disadvantages of this method are: [0003] First, the calibration workload is heavy, and operators are often physically exhausted. [0004] Second, the positions that can be corrected by hammering are limited, and some positions cannot be calibrated, resulting in the fact that after the bending plate is calibrated, the size meets the requirements, but the shape accuracy is not good. [0005] Third, the efficiency of manual hammer correction is very low, and the quality of correction is also poor, which is not conducive to the realization of standard operation and assembly line op...
