Description

Technical Field

[0001] The utility model relates to the technical field of motor maintenance, in particular to a motor slip ring replacement device. Background Art

[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is represented by the letter M (D in the old standard) in the circuit. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, the replacement of slip rings is an important maintenance link in the service life of the motor. It is also one of the largest parts that need to be replaced during the maintenance of the motor in its service life. The slip rings are usually replaced by replacing the device.

[0003] According to the Chinese patent application number 202021841447.9, a motor slip ring replacement device is disclosed, which specifically relates to the field of motors, including a workbench and at least four fixing mechanisms symmetrically installed above the workbench, wherein slide grooves are symmetrically provided on both sides of the workbench, and support rods are vertically slidably connected inside the slide grooves, and bolts are provided on the outside of the support rods, and the support rods are located on both sides of the fixing mechanism to support the motor; the fixing mechanism includes a slider, and fixing rods are fixedly provided on adjacent surfaces of the slider, and main rings are fixedly connected to adjacent surfaces of the fixing rods, and side rings are provided on the upper and lower sides of the main ring, and a fixing layer is connected between the main ring and the side ring, and a connecting rod is hinged on the side of the side ring away from the fixing layer.

[0004] The above scheme is adopted, by providing a main ring and a side ring, the contact area is large, the fixation is reliable, and motors of different shapes can be stably fixed to prevent the replacement of the slip ring from being affected by shaking when the replacement device replaces the slip ring. However, in the actual use of the above scheme, the support rod can be lifted and lowered in the vertical direction with the cooperation of the slide groove and the bolt to adjust the height of the motor. It is necessary to unscrew the bolt to release the limit and then tighten the bolt limit again after lifting the motor to adjust the height of the motor. It is troublesome to adjust the height of the motor and there are certain shortcomings. To this end, we provide a motor replacement slip ring device to solve the above problems.
