[0003] The normal operation of the existing electric mine truck directly relates to the efficiency and progress of the whole mining operation, and the electric engine rotor as a key component needs to be regularly overhauled and maintained after long-term high-load operation to ensure its stable performance and reliable operation.

[0004] The traditional overhauling method is to directly place the engine rotor on the ground for operation, however, due to the particularity of the application scene, the engine rotor of mine truck often has large specifications and quality, when the heavy rotor directly contacts with the ground, the part of the rotor contacting with the ground will bear huge pressure, which is easy to cause deformation and damage of the rotor surface, especially for some high-precision rotor components such as rotor core and winding, even a small deformation may affect its electromagnetic performance and mechanical balance, thereby reducing the overall efficiency and reliability of the engine, and even may cause serious failure, increase maintenance cost and downtime, bring huge economic loss to mining production, in view of this, the utility model is proposed. UTILITY MODEL CONTENT

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art, and provide a kind of auxiliary equipment for the engine rotor of mine truck overhauling, which can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above technical problems, the basic idea of the technical scheme of the utility model is: a kind of auxiliary equipment for the engine rotor of mine truck overhauling, including mobile base, further comprising: support plate, symmetrically fixedly connected on the both sides of the mobile base;Mounting plate, connected between the two support plates;Push handle, fixedly connected on one side of the two support plates;Reduction motor, fixedly installed on the mounting plate;Fixed clamping shell, fixedly connected on the output end of the reduction motor;Clamping assembly for clamping and fixing the rotor, installed on the fixed clamping shell.

[0007] Further, the clamping assembly comprises clamping plates and adjusting screws, the clamping plates are circumferentially and equidistantly arranged in the fixed clamping shell, and the adjusting screws are circumferentially and equidistantly screwed on the fixed clamping shell, and each adjusting screw is rotationally connected with an adjacent clamping plate.

[0008] In order to facilitate the position adjustment of the clamping plates by the adjusting screws without supporting the clamping plates, further, guide rods are symmetrically and fixedly connected to the clamping plates on both sides of the adjusting screws, and the guide rods are slidingly connected to the fixed clamping shell.

[0009] In order to increase the friction between the clamping plates and the central rotating shaft of the engine rotor of the mining truck, thereby improving the clamping stability of the central rotating shaft of the engine rotor of the mining truck, further, a rear rubber pad is fixedly attached to the clamping surface of the clamping plate.

[0010] In order to facilitate the clamping and fixing of the rotor at the central shaft of the fixed clamping shell, and to position the engine rotor of the mining truck, further, a plurality of positioning grooves with different sizes are formed in the inner wall of the fixed clamping shell, and the positioning grooves are on the same center line.

[0011] In order to facilitate the staff to adjust the engine rotor of the mining truck to different inclined states according to needs, further, the mounting plate is rotationally connected between the two supporting plates through a rotating shaft, a hydraulic telescopic rod is rotationally connected to the mounting plate at a position between the two supporting plates on the moving base, and the telescopic end of the hydraulic telescopic rod is rotationally connected to one side of the lower end of the mounting plate.

[0012] In order to facilitate the staff to take the required tools, further, a through groove is formed in the moving base, and a tool box is placed in the through groove.

[0013] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model drives the fixed clamping shell to rotate through the speed reducer, so that the rotor can rotate 360 degrees in all directions, which means that the maintenance personnel can view and maintain every detail of the rotor without moving around the rotor or turning the rotor multiple times, greatly improving the convenience and comprehensiveness of maintenance.

[0014] In the past, when maintaining large rotors on the ground, the maintenance personnel often need to spend a lot of time and effort to turn and adjust the position of the rotor due to the heavy weight and inconvenience of moving the rotor, and the use of the auxiliary device suspends the rotor and can rotate flexibly, greatly reducing the workload of manual handling and adjustment, and greatly shortening the maintenance time.

[0015] The rotor is suspended, which completely eliminates the risk of deformation damage caused by uneven pressure when placed on the ground, especially for some high-precision and high-value rotors, and the protection is particularly important, which ensures that the physical properties and precision of the rotor before and after maintenance are not affected, prolongs the service life of the rotor, reduces the high replacement cost and maintenance cost caused by rotor damage, and brings significant benefits to the long-term maintenance and operation cost control of the mine equipment.
