DETAILED DESCRIPTION

[0015] The embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] like Figures 1 to 7 As shown, the present invention discloses an axle box unloading machine 100, which includes a base 1, an unloading head 2, a special screw 5, a push wheel cylinder 6, and a material receiving plate 7; a track 12 connected to a workshop is provided in the middle of the base; the unloading head is axially symmetrically arranged at two ends of the base, an unloading cylinder and a top device are arranged in the unloading head, the push wheel cylinder is arranged in the base, and the material receiving plate is arranged below the unloading head; The base is hollow inside, and axial grooves are provided at both ends of the base, which facilitate the left and right movement of the lifting cylinder under the unloading head; A withdrawal plate 23 is provided in front of the withdrawal head, and a T-shaped groove 24 is provided on the withdrawal plate; A movable plate 25 is provided under the unloading head, and a stand 11 is provided on one side of the movable plate. When working, the unloading head and the stand move left and right simultaneously with the movable plate. A guide moving force 3 and a guide moving assembly 4 are provided between the moving plate and the base; a guide moving assembly 4 is provided between the withdrawal head and the stand, and a guide moving force 3 is provided under the withdrawal head. The lifting cylinder piston rod of the guide moving force vertically passes through the moving plate and is connected to the bottom of the withdrawal head. The cylinder sleeve is fixed on the moving plate; the lifting of the cylinder piston rod drives the withdrawal head to rise and fall on the stand; The special screw is shaped like a cross and is used in conjunction with the withdrawal plate.

[0017] The guiding moving force is an oil cylinder.

[0018] The guide assembly is a guide rail and guide groove pair.

[0019] The present invention is specially provided with electric control and hydraulic system.

[0020] The working process of the present invention is as follows: The wheelset with the axle box enters the center of the machine. Before removing the axle box, first remove the axial front and rear end cover screws of the axle box and remove the front end cover, then screw two sets of special screws into the screw holes of the upper end cover and tighten them. The removal head is moved to the bottom of the axle box and then rises, and the special screws are inserted into the T-slot. The removal cylinder is started, and the piston rod moves forward and the top device presses against the axle positioning hole. The piston end face is pressed against the axle end face, and the cylinder continues to move forward. The removal plate retreats until the axle box is removed, and the receiving plate supports the axle box. The wheel pushing cylinder under the wheel works to push the removed wheelset out of the machine and into the workshop track; remove the axle box, the machine returns to its original state, and enters the next working state.

[0021] The above is only one of the embodiments of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
