Description

Technical Field

[0001] This utility model belongs to the field of rail locomotive maintenance technology, specifically relating to an auxiliary device for painting the surface of a rail locomotive motor boom. Background Technology

[0002] The motor boom of a rail locomotive, as a crucial component supporting and securing the motor, plays a vital role in routine maintenance and upkeep. However, in traditional workflows, painting the motor boom requires repeated repositioning to ensure even coating across all areas. This not only increases operational complexity but also significantly reduces efficiency. More seriously, frequent repositioning can lead to unnecessary damage to the boom or uneven coating, affecting both aesthetics and protective effectiveness. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to design an auxiliary device for painting the surface of the motor boom of a rail locomotive, in order to solve the problems mentioned in the background technology, such as complicated operation, low work efficiency and unnecessary damage to the boom caused by frequent flipping.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an auxiliary device for painting the surface of a rail locomotive motor boom, comprising a frame, a motor boom, a lifting device, a rotating support base, a servo motor, and a control console. The frame includes a base frame and a portal frame. The portal frame is located in the middle of the base frame, and the lifting device is mounted on the portal frame. The rotating support base is mounted on the base frame. The upper part of the motor boom is connected to the lifting device, and the lower part of the motor boom is connected to the rotating support base via a pin. The rotating support base rotates under the action of the servo motor, thereby causing the motor boom to rotate and perform paint coating operations. The control console is located on one side of the frame and controls the operation of the servo motor.

[0005] The base frame includes columns A, connecting rods, and crossbeams. There are four columns A arranged in a rectangular array at the four corners. There are two connecting rods and two crossbeams. The two columns A in the longitudinal direction are connected by connecting rods, and the two columns A in the transverse direction are connected by crossbeams. The crossbeams are provided with support mounting holes at intervals, and the support mounting holes on the two crossbeams are staggered. One end of the crossbeam is provided with a motor mounting plate for fixing a servo motor, and the motor mounting plates on the two crossbeams are staggered.

[0006] The gantry frame includes two columns B and a support beam. The two columns B are respectively located in the middle of two connecting rods. A support beam is provided between the tops of the two columns B. The cross-section of the support beam is an upward-opening "V" shape. Hanger mounting slots are provided alternately on both sides of the support beam.

[0007] The mounting holes for the support seats on the two crossbeams correspond to the mounting slots for the lifting devices on both sides of the support beam.

[0008] The lifting device consists of an upper lifting ring and a lower connecting frame integrated together. The lifting ring is a cylindrical rod-shaped structure with a lifting hole at the top. The middle part of the rod body of the lifting ring matches the lifting device mounting groove on the support beam. The bottom of the lifting ring is fixedly connected to the middle part of the connecting frame. The connecting frame is an "n"-shaped structure with an opening at the bottom. Both sides of the opening end of the connecting frame are provided with inward 90-degree bends. At the center of the bends, there is a cylindrical protrusion that matches the upper mounting hole of the motor lifting rod.

[0009] The rotating support base consists of an upper base body and a lower rotating shaft connected as one unit. The base body has a U-shaped structure with an open top. A lug plate is horizontally provided in the middle of the inner side wall of the base body. The surface of the lug plate has a through hole corresponding to the mounting hole of the lower part of the motor rod. The lower part of the motor rod is mounted on the base body by the cooperation of a pin with the through hole. A support plate perpendicular to the inner side wall of the base body is provided on one side. The lug plate is reinforced by the cooperation of the support plate and the inner side wall of the base body. The rotating shaft is located at the center of the bottom surface of the base body. The end of the rotating shaft passes through the support mounting hole on the crossbeam and is connected to the main shaft of the servo motor by a chain. The servo motor drives the rotating shaft to rotate through the chain, thereby driving the motor rod mounted on the rotating support base to rotate.

[0010] The support mounting hole includes an end cap, a bearing housing, and a bearing. The bearing housing is disposed in the support mounting hole, and the outer end face of the bearing housing is in contact with the inner end face of the bearing. The outer end face of the bearing is provided with an end cap that is fixed to the crossbeam by screws. The inner ring of the bearing is interference-fitted with the rotating shaft of the rotating support.

[0011] The number of mounting holes for the support base is multiple, and each mounting hole is equipped with a corresponding rotating support base. The rotating shafts of the rotating support bases on the same crossbeam are connected to the servo motor via chains.

[0012] The beneficial effects of this utility model are: it enables painting of motor booms; under the control of a servo motor, the position of the motor boom changes, avoiding collisions caused by repeated hoisting. The structural height conforms to ergonomics, facilitating painting operations and reducing labor intensity. The staggered placement of the motor booms on the device improves space utilization. The standardized configuration allows for painting operations of a single locomotive motor boom at a time. Attached Figure Description
