Description

Technical Field

[0001] This utility model relates to a piece of equipment for rail transit, specifically a type of axle box unloading machine. Background Technology

[0002] It is understood that the existing technology and equipment cannot complete the removal of the axle box on the subway wheelset because only the axle box needs to be removed and the bearing does not need to be removed at the same time. People have tried to use pullers to achieve the removal, but it is too time-consuming and laborious, and very troublesome, which cannot meet the needs of mechanized and modernized production. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a shaft box unloading machine with a scientific and reasonable structure, which can mechanically and quickly unload shaft boxes, saving time and labor, and meeting the needs of modern production lines.

[0004] To achieve the above objectives, the technical solution of this utility model is a shaft box unloading machine, which involves an unloading head. An unloading frame is provided in front of the unloading head. The unloading frame is formed by connecting an mounting plate and an unloading plate at the four corners with bolts. The unloading plate is parallel to the mounting plate and has a gap in the middle. The mounting plate is mounted on the unloading head, and the U-shaped opening of the unloading plate faces upward.

[0005] The unloading rack is equipped with an unloading fixture, which has large and small rings at both ends of the pipe section, with four screw lugs evenly distributed on the large ring.

[0006] A support plate is provided at the lower front of the unloading plate.

[0007] The beneficial effects of this utility model are that it has a scientific and reasonable structure, is sturdy and stable, and the unloading frame and unloading tooling can quickly connect to the unloading shaft box, saving time and effort and meeting the needs of modern production lines.

[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] like Figures 1 to 7 As shown, this utility model discloses a shaft box unloading machine 100, which relates to an unloading head 1. The unloading head is symmetrically arranged at both ends on the base of the shaft box unloading machine. The unloading head is provided with an unloading cylinder. An unloading frame 11 is provided in front of the unloading head 1. The unloading frame is formed by connecting the mounting plate 111 and the unloading plate 112 at the four corners by bolts 113. The unloading plate is parallel to the mounting plate and has a gap in the middle. The gap is sufficient to allow one end of the small ring of the unloading tool to smoothly enter and exit the unloading plate. The mounting plate is mounted on the unloading head, and the U-shaped opening of the unloading plate faces upward.

[0022] A dismantling fixture 2 is provided in conjunction with the dismantling frame. The dismantling fixture has large and small rings 22 at both ends of the pipe section 21. The large ring has four screw lugs 23 evenly distributed on it. The dismantling fixture is fixed to the axle box with bolts.

[0023] A support plate 3 is provided at the lower front of the unloading plate. The support plate supports the unloaded axle box to prevent it from falling directly and being damaged.

[0024] This utility model is equipped with an electrical control and hydraulic system.

[0025] The working process of this utility model is as follows:

[0026] The wheelset with the axle box enters the center of the machine. Before removing the axle box, remove the axial front and rear end cover screws of the axle box and remove the front cover. Then, screw the removal tool into the screw hole of the front end cover and tighten it.

[0027] like Figure 4 As shown, start the unloading head to move the unloading frame under the axle box;

[0028] like Figure 5 As shown, raising the unloading head allows the small ring of the unloading tool to enter the unloading plate;

[0029] like Figure 6 As shown, the unloading cylinder in the unloading head works, and the cylinder piston rod pushes against the end face of the wheel set axle, and the cylinder continues to exert force until the axle box is unloaded;

[0030] like Figure 7 As shown, the unloading head returns to its original position to its initial state under the action of the transverse hydraulic cylinder.

[0031] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
