[0024] Preferably, the lifting part includes a support frame 5, a rotating shaft 6, an eccentric wheel 7 and a first handle 8. The support frame 5 is fixedly set on the base 2, and a bearing is set on the support frame 5. The rotating shaft 6 is passed through the bearing of the support frame 5, and the eccentric wheel 7 is passed through the rotating shaft 6. The rotation center of the eccentric wheel 7 is set at a position deviating from its center of circle. The liftable platform 3 is mounted on the eccentric wheel 7, and the first handle 8 is connected to one end of the rotating shaft 6. When the first handle 8 is rotated, the rotating shaft 6 drives the eccentric wheel 7 to rotate, and the liftable platform 3 moves up and down with the rotation of the eccentric wheel 7.

[0025] The detection tooling 4 also includes a limit device and a spring locking part. The limit device includes a guide column 9 and a guide sleeve 10 that cooperate with each other. The guide column 9 is vertically fixed on the base 2, and the guide sleeve 10 is arranged on the liftable platform 3. The guide column 9 is inserted into the guide sleeve 10, and the liftable platform 3 can slide up and down along the guide column 9. The spring locking portion includes a U-shaped groove 111, an elastic clip 112 and a second handle 113. The U-shaped groove 111 is fixedly connected to a side of the base 2 close to the first handle 8. The elastic clip 112 is movably connected in the U-shaped groove 111. The second handle 113 is connected to the elastic clip 112. When the first handle 113 rotates clockwise and falls into the U-shaped groove 111, the elastic clip 112 pops out from the U-shaped groove 111. The protrusion 114 on the elastic clip 112 abuts against the first handle 8 to restrict the first handle 8 in the U-shaped groove 111. When the second handle 113 is lifted upward, the protrusion 114 will retract into the U-shaped groove 111 along with the elastic clip 112.

[0026] The casting positioning support part includes a casting positioning boss 12 and a casting support frame 13, and the casting positioning boss 12 and the casting support frame 13 are arranged on the liftable platform 3. The support part includes a column 14 and a single arm 15, and the hoisting part includes an electric hoist 16 and a hook 17. The column 14 is fixed on the steel structure frame 1, the single arm 15 is movably connected to the top of the column 14, the electric hoist 16 is connected to the single arm 15, and the hook 17 is connected to the cable of the electric hoist 16.

[0027] The column 14 and the single arm 15 are connected by a bearing. The single arm 15 can rotate horizontally around the column 14. A horizontal track 151 is set at the lower end of the single arm 15. A pulley 161 that matches the track 151 is connected to the electric hoist 16, and the pulley 161 can move horizontally along the track 151.

[0028] The wheel is a universal wheel 18 , and a locking device 19 is provided on the universal wheel 18 .

[0029] The working process and principle of the above-mentioned embodiment of a movable large-scale new energy gearbox housing casting deformation quick detection fixture are as follows:

[0030] First, by pushing the movable device, driven by the universal wheel 19, the entire device moves with the movable device to a suitable position in the casting area of ​​the large new energy gearbox housing casting, and the locking device 19 is used to fix the entire device. Then start the lifting device, including rotating the single arm 15 and moving the electric hoist 16. The single arm 15 rotates around the column 14 to the top of the casting to be tested, and then pushes the electric hoist 16 so that the electric hoist 16 moves along the track 151 on the single arm 15 to a position suitable for lifting. Then start the electric hoist 16, and the hook 17 descends to the casting to be tested along the cable. The worker hooks the hook 17 on the casting, and then starts the electric hoist 16 again to lift the casting. Move the single arm 15 and the electric hoist 16 to place the casting steadily on the liftable platform 3 of the inspection tooling, align the positioning holes on the casting with the positioning boss 12 of the casting, and support the casting support frame 13.

[0031] like Figure 6 As shown, after the casting is placed in place, the worker shakes the first handle 8 clockwise, and the first handle 8 drives the rotating shaft 6 to rotate in the bearing of the support frame 5, and the eccentric wheel 7 connected to the rotating shaft 6 also starts to rotate. Since the center of the circle of the eccentric wheel 7 and its rotation center do not coincide, the distance from the edge of the eccentric wheel 7 to the rotation center will change during the rotation of the eccentric wheel 7. Therefore, as the first handle 8 rotates, the liftable platform 3 will gradually rise under the push of the eccentric wheel 7. When the liftable platform 3 rises to the preset position, the first handle 8 just rotates into the U-shaped groove 111, and the elastic buckle 112 pops out from the inside of the U-shaped groove 111. The protrusion 114 on the elastic buckle 112 abuts against the upper end of the first handle 8, restricting the first handle 8 in the U-shaped groove 111, thereby restricting the liftable platform 3 to a preset height. Subsequently, it is convenient for workers to use various detection measuring tools to detect the casting.

[0032] like Figure 5 As shown, after the casting inspection is completed, the second handle 113 is pushed upward, and the protrusion 114 on the elastic buckle 112 is retracted into the U-shaped groove 111 along with the elastic buckle 112. Without the restriction of the elastic buckle 112, the first handle 8 is turned counterclockwise, and the lifting platform 3 gradually descends. Finally, the lifting device is started to lift the tested casting away from the inspection tooling, and the entire inspection process is completed.

[0033] The above specific implementation methods are only for illustrating the technical concept and structural features of the present invention, and the purpose is to enable relevant persons familiar with this technology to implement it. However, the above content does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should fall within the protection scope of the present invention.
