Description

Technical Field

[0001] The utility model belongs to the technical field of three-phase asynchronous motors, in particular to a three-phase asynchronous motor which is easy to move. Background Art

[0002] The three-phase asynchronous motor consists of two basic parts: a fixed stator and a rotating rotor. The rotor is installed in the inner cavity of the stator and is supported on two end covers with the help of bearings. Most three-phase asynchronous motors are heavy, making it inconvenient to transfer the three-phase asynchronous motor.

[0003] At present, some three-phase asynchronous motors are provided with rollers on their bases to facilitate the transfer of the three-phase asynchronous motors. However, these rollers are mostly fixed and cannot be stored, which makes the installation of the motor more troublesome and may affect the normal use of the motor. In addition, the motor is unstable and often shifts, making it inconvenient to use. Summary of the invention

[0007] A movable mechanism is provided inside each of the plurality of second mounting grooves, and the movable mechanism includes a slide groove opened on the front and rear inner walls of the second mounting groove, a slider is slidably connected inside the slide groove, a movable block is fixedly connected to the outer wall of the threaded rod with a thread, a rotating shaft is rotatably connected between the front and rear inner walls of the second mounting groove, a support rod is fixedly connected to the outer wall of the rotating shaft, a roller is rotatably connected to the other end of the support rod, a connecting plate is fixedly connected to the outer wall of the rotating shaft, and a movable rod is movably connected between the side end surface of the connecting plate and the upper end surface of the movable block.

[0008] In order to make the driving gear rotate, as a three-phase asynchronous motor that is easy to move in the utility model, a dual-axis motor is embedded and installed on the lower end surface of the support plate, and the output ends of the dual-axis motor extend to the interior of the two first mounting grooves respectively and are fixedly connected to a driving gear that meshes with the driven gear.

[0009] In order to prevent the movable block from falling off the outer wall of the threaded rod, as a preferred embodiment of the utility model of a three-phase asynchronous motor that is easy to move, the other ends of the two threaded rods are fixedly connected to the limit blocks.

[0010] In order to make the movable block move in opposite directions, as a conveniently movable three-phase asynchronous motor of the utility model, preferably, the thread directions of the two threaded rods fixedly connected to the shaft rod are opposite.

[0011] In order to reduce the vibration of the device, as a preferred embodiment of the utility model of a three-phase asynchronous motor that is easy to move, the outer wall of the roller is fixedly connected with a rubber layer.

[0012] In order to make the operation of the device more convenient, as a preferred embodiment of the utility model of a three-phase asynchronous motor that is easy to move, the upper end surface of the support plate is fixedly connected with a control switch.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model drives the driving gear to rotate through the output end of the double-axis motor, so that the driving gear drives the driven gear meshing with it to rotate, and the driven gear drives the shaft rod to rotate the threaded rods at both ends of the shaft rod, so that the movable blocks on the outer walls of the two threaded rods move in opposite directions, making the device easier to operate, and at the same time, the movable block drives the slider to slide inside the slide groove, so that the movable block moves more smoothly.

[0015] In addition, the utility model drives the movable rod to move through the movable block, so that the movable rod changes its angle and pushes the connecting plate. The connecting plate changes its angle and drives the rotating shaft to rotate, so that the angle of the support rod changes, and the roller is driven to move, so that the roller is easier to be accommodated in the second placement groove, thereby preventing the motor from shifting.
