[0002] Most existing electric locomotives have a total of 12 axle end caps. Among them, the axle end caps with grounding devices are heavy due to the presence of copper components, weighing 20-30 kilograms. The maintenance and installation work is the responsibility of the locomotive depot's running crew. Currently, the locomotive depot does not have dedicated installation equipment, and overhead crane hoisting operations are limited, so the installation relies entirely on manpower.

[0003] During installation, one person must lift the shaft end cap, place it on their thigh, support it with their knee, and align the screw holes on the shaft end cap with the screw holes on the shaft housing. Then, tighten the bolts with both hands. If the operation is unsuccessful on the first attempt, the entire shaft end cap must be placed on the ground. This process is physically demanding for the workers and is quite inconvenient to install. Utility Model Content

[0004] The purpose of this utility model is to provide an electric locomotive axle end cover installation device to solve the problems mentioned in the background art, which are that the installation process is prone to causing great physical exertion to the workers and is also inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric locomotive axle end cover installation device, comprising a bracket, a mounting base plate, and a guide plate. Vertical guide rods are fixed to both sides of the top of the mounting base plate, and a stop block is fixed to the top of each vertical guide rod. A screw is mounted on the top of the guide plate, and a horizontal guide rod is provided below the screw. A movable sleeve is externally connected to the screw and the horizontal guide rod. A support plate is fixed to the top of the movable sleeve using a connecting block. Sliding grooves are formed on both sides of the top of the support plate, and a slider is embedded in each groove. An arc-shaped clamping plate is fixed to the top of each slider. Vertical plates are fixed to both sides of the top of the support plate, and a first telescopic rod is connected to the side of each vertical plate. The side of the first telescopic rod contacts and is assembled with the arc-shaped clamping plate. An adhesive layer is fixed to the inner arc surface of the arc-shaped clamping plate, and a protective pad is fixed to the outer surface of the adhesive layer. Steel balls are assembled between the screw and the movable sleeve.

[0006] As a further technical solution of this utility model, the adhesive layer and the protective pad form an adhesive connection, and the upright plate is symmetrically distributed about the central axis of the supporting plate.

[0007] As a further technical solution of this utility model, the slide groove and the slider form a sliding connection, and the slide groove is symmetrically distributed about the central axis of the support plate.

[0008] As a further technical solution of this utility model, the vertical guide rods are symmetrically distributed about the central axis of the mounting base plate, and through holes are provided on both sides of the guide plate.

[0009] As a further technical solution of this utility model, the through hole is connected to a groove, and the groove is embedded with a ball.

[0010] As a further technical solution of this utility model, a first mounting seat is fixed on the top of the bracket, and an assembly rod is inserted in the first mounting seat. The assembly rod is distributed at the bottom of the mounting base plate.

[0011] As a further technical solution of this utility model, a locking pin is inserted between the first mounting base and the assembly rod, and locking nuts are externally connected to both ends of the locking pin.

[0012] As a further technical solution of this utility model, a cylinder is installed at the middle position of the bottom of the mounting base plate, and a hydraulic telescopic rod is connected to the output end of the cylinder. The bottom of the hydraulic telescopic rod is connected to the guide plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this electric locomotive axle end cover installation equipment not only improves the subsequent clamping and positioning capability, but also improves the lifting capability and lateral adjustment capability of the installation equipment.

[0014] (1) By opening the groove in the top of the support plate and then installing and fixing the upright plate on both sides of the top of the support plate, the shaft end cap is placed above the support plate during operation. Since the first telescopic rod is installed on the side of the upright plate, the arc-shaped clamp can be pushed to move after the first telescopic rod is in operation. When moving, the slider slides in the groove. When the arc-shaped clamp moves to both sides of the shaft end cap, the two arc-shaped clamps are used to clamp the shaft end cap. During clamping, the protective pad is bonded and assembled with the adhesive layer on the side of the arc-shaped clamp, thus reducing the wear problem caused by hard contact with the shaft end cap. Therefore, the overall clamping and positioning ability is improved in the working process.

[0015] (2) By assembling the assembly rod in the first mounting seat, and then using a snap-fit ​​connection between the first mounting seat and the assembly rod, and then using a locking nut to lock the connection after insertion, the hydraulic telescopic rod can be hydraulically telescopic after the cylinder works to push the guide plate up and down during movement. When moving, the vertical guide rod passes through the through hole to guide, and after connecting the groove in the through hole, the ball is embedded in the groove to form rolling protection, thereby improving the overall lifting capacity during the working process.

[0016] (3) The screw is assembled on the upper part of the guide plate using a plate assembly. A servo motor is mounted on the side of the plate. After the servo motor works, it can drive the screw to rotate. At this time, the movable sleeve is connected to the outside of the screw and the horizontal guide rod. Therefore, the lateral position of the movable sleeve can be adjusted. This process is guided by the horizontal guide rod. Furthermore, with the addition of steel balls, the wear problem caused by sliding is reduced, and the overall lateral adjustment capability is improved. Attached Figure Description
