Description

Technical Field

[0001] This utility model belongs to the technical field of equipment maintenance tools, specifically relating to a maintenance bracket for the rotor of a wheel motor of a heavy-duty mining truck. Background Technology

[0002] With the advancement of science and technology, the load capacity of heavy-duty mining trucks is constantly increasing, leading to a corresponding increase in the size of their components. For example, the wheel motor of a 100-ton mining truck weighs over 3 tons, while its internal rotor weighs over 1 ton, presenting challenges for storage, transportation, and maintenance. Placing the wheel motor rotor directly on the ground without adequate protection can easily cause moisture absorption in the armature windings, potentially leading to a decrease in internal insulation. Prolonged fixed storage can cause localized stress on the armature windings, resulting in rotor de-rounding and affecting normal operation. The cylindrical rotor is susceptible to rolling during transport if not securely fastened, and collisions between the armature windings and the transport vehicle can easily damage it. Furthermore, before installing a spare wheel motor rotor, the commutator surface needs to be uniformly polished to remove the oxide layer to ensure conductivity; however, the lack of specialized maintenance tools makes it impossible to guarantee the quality of equipment maintenance.

[0003] In view of the above factors, this utility model provides a maintenance bracket for the rotor of a heavy-duty mining truck wheel motor, thereby solving the problems existing in the storage, transportation and maintenance of the wheel motor rotor. Utility Model Content

[0006] The positioning mechanism includes a connecting frame or a rolling assembly, which supports both ends of the automobile wheel motor rotor via the positioning device.

[0007] Furthermore, the positioning mechanism is detachably connected to the connecting plate.

[0008] Furthermore, the detachable connection between the connecting plate and the positioning mechanism is a bolt connection.

[0009] Furthermore, the connecting plate is movably connected to a positioning mechanism, which is capable of moving vertically up and down relative to the connecting plate.

[0010] Furthermore, the bottom of the connecting frame or rolling assembly of the positioning mechanism is provided with a connecting end by welding. The connecting end has a circular structure and extends downward through the connecting frame to connect with the lifting structure.

[0011] Furthermore, the connecting frame is fixedly welded with a limiting sleeve, and the connecting end extends downward through the connecting frame, passes through the limiting sleeve, and connects to the output end of the lifting structure.

[0012] Furthermore, the lifting structure is a lifting cylinder, and the lifting structure is provided in each of the connecting frames symmetrically arranged on the support frame;

[0013] The lifting structure moves up and down synchronously, and the synchronous lifting structure is achieved through a PLC controller.

[0014] Furthermore, the connecting frame of the positioning mechanism has an arc-shaped structure, and a fixed cover that is detachably connected to the connecting frame is configured to conform to the shape of the connecting frame.

[0015] Furthermore, the rolling assembly of the positioning mechanism consists of two bearing discs and a steel structure connecting bracket. The inner sleeve of the bearing is welded to the shaft pin on the steel structure connecting bracket, and the outer sleeve of the bearing is a free end.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
