Then, the lifting arm 13 is extended below the tram. The output shaft of the driving motor I17 is driven to rotate so as to drive the screw rod I18 to rotate, and the lifting arm 13 slides along the height direction of the upright post 11 under the rotation of the screw rod I18, so that the tramcar is lifted to a proper height.
After the lifting arm 13 reaches a certain height, the output shaft of the second driving motor 213 rotates to drive the rotating shaft 212 to rotate, so that the supporting rod 21 rotates around the rotating shaft 212 until the axial direction of the supporting rod 21 is vertical.
The driving handle 233 rotates so as to drive the pinion 232 to rotate. The butterfly bevel gear 231 is driven to rotate, the butterfly bevel gear 231 drives the screw rod II 221 to rotate, and the sleeve 22 slides along the axial direction of the supporting rod 21 under the driving of the screw rod II 221 until the bottom of the sleeve 22 is abutted against the ground. Therefore, the supporting rod 21 and the sleeve 22 play a role in supporting one end, far away from the upright post 11, of the lifting arm 13, and after the lifting arm 13 reaches a certain height, the safety and stability of the lifting machine are improved, and the occurrence of damage to maintenance personnel is reduced.
The connecting shaft 243 is rotated so that the smooth section of the connecting shaft 243 is inserted between the positioning seat 241 and the supporting leg 242, so that the supporting leg 242 rotates around the positioning seat 241. After the connecting shaft 243 is properly positioned, the threaded section of the connecting shaft 243 is screwed with the positioning seat 241 and the supporting leg 242, so that the angle between the positioning seat 241 and the supporting leg 242 is fixed. The connecting ring 24 is then rotated so that the connecting ring 24 slides vertically along the sleeve 22 until the bottom of the support leg 242 abuts the ground. Thereby increasing the support surface of the sleeve 22 and the supporting effect of the support rod 21 and the sleeve 22 on the lifting arm 13, and thus the stability of the lifting machine.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
