[0029] like Figure 1 As shown, a flaw detection platform for forged shafts of hydropower gate cranes includes a gantry frame 1, a crossbeam 105, and two columns 104 fixedly connected to the crossbeam 105, with the extension direction of the crossbeam 105 being the first direction; two lifting members 4, respectively disposed on the two columns 104, with ramps provided on the opposite sides of the two lifting members 4, and the columns 104 being provided with thrust units for driving the lifting members 4 to move along the first direction; rotating rollers 405, horizontally distributed on the top surface of the lifting members 4 perpendicular to the first direction; and a moving mechanism 3, disposed at the bottom end of the columns 104.

[0030] The aforementioned flaw detection platform is suitable for assisting in the flaw detection of columnar forgings, such as forgings for motor shafts of hydroelectric gates. During use, the moving mechanism 3 facilitates the movement of the flaw detection platform, allowing the gantry frame to be erected above the end frame. Then, two thrust units push the two lifting components 4 closer together. During the movement of the lifting components 4, the ramps on the lifting components 4 contact the forging, causing the forging to move upwards along the ramps, thus lifting the forging. The lifted forging is supported by two rotating rollers 405, which drive the forging to rotate. During this process, the operator holds an ultrasonic probe to inspect the forging. The rotation of the forging reduces the operator's movement range, improves the convenience of flaw detection, and reduces the operator's workload.

[0031] Further improvement is, as shown in Figure 2 and 4 , the thrust unit includes a cylinder 406 distributed on the column 104 along the first direction, the movable end of the cylinder 406 is fixedly connected with the lifting piece 4; the column 104 is provided with a guide hole 103 extending along the first direction, the guide hole 103 is coaxially and slidingly fitted with a guide column 401, the guide column 401 is fixedly connected with the lifting piece 4.

[0033] Further improvement is, as shown in Figure 1 , the moving mechanism 3 includes a connecting sleeve 102, a spring 301, a rotating shaft 302 and a moving wheel 303, the rotating shaft 302 is vertically arranged, the moving wheel 303 is fixedly connected with the bottom end of the rotating shaft 302, the connecting sleeve 102 is coaxially sleeved on the rotating shaft 302, the two ends of the spring 301 are respectively connected with the connecting sleeve 102 and the top end of the rotating shaft 302, and the connecting sleeve 102 is fixedly connected with the column 104.

[0034] Specifically, the moving wheel 303 is arranged to facilitate the movement of the position of the flaw detection platform, so as to facilitate the adjustment of the relative position between the lifting piece 4 and the forge piece, and facilitate the lifting of the forge piece; the rotating shaft 302 can rotate in the connecting sleeve 102, so as to adjust the orientation of the moving wheel 303, so as to change the moving direction of the flaw detection platform, and further improve the convenience of using the flaw detection platform; the rotating shaft 302 can also be lifted along the connecting sleeve 102, when the lifting piece 4 lifts the forge piece, the lifting piece 4 is pressed down under the action of the gravity of the forge piece, then the moving wheel 303 is retracted, and the bottom support of the gantry 1 is erected on the ground, so as to prevent the displacement of the flaw detection platform during the flaw detection; after the lifting piece 4 moves away from each other, the forge piece is unloaded from the lifting piece 4, at this time, under the action of the spring 301, the moving wheel 303 lifts the gantry 1, at this time, the moving wheel 303 touches the ground, so as to facilitate the movement of the flaw detection platform.

[0035] Further improvement is, as shown in Figure 5 , the two ends of the lifting piece 4 are rotatably provided with support wheels 403. The arrangement of the support wheels 403 can reduce the friction between the lifting piece 4 and the ground during movement, reduce the wear of the lifting piece 4, and at the same time reduce the load of the cylinder 406, and improve the energy saving effect.

[0036] Further improvement is, as shown in the figure, the top end of the lifting piece 4 is provided with a containing groove 402 for containing the rotating roller 405, the depth of the containing groove 402 is less than the diameter of the rotating roller 405, and the lifting piece 4 is further provided with a motor 404 for driving the rotating roller 405 to rotate.

[0038] Specifically, since coupling agent needs to be applied on the surface of the forging during ultrasonic flaw detection, and the coupling agent needs to be removed after the flaw detection is completed, the workload is increased; after the forging is lifted, the rubber strip 202 and the sponge strip 203 are abutted against the surface of the forging from both sides, and the coupling agent on the surface of the forging is removed through the rubber strip 202 and the sponge strip 203 during the driving of the forging by the rotating roller 406, thereby omitting the subsequent manual cleaning step and improving the practicability of the flaw detection platform.
