[0026] The following will describe the embodiments of the present invention 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.

[0027] As Figures 1 to 9 shown, the present invention discloses an axle box removal machine 100, including a frame 1, a lifting and supporting device 2, and a removal device 3. The lifting and supporting device is arranged in the middle of the frame, and the removal device is symmetrically arranged on both ends of the frame;

[0028] The removal device is provided with a removal oil cylinder 31, a center point device 33 is arranged in front of the removal oil cylinder piston rod 32, and a removal concave fork assembly 34 is connected to the bottom of the removal device;

[0029] A guiding and moving assembly 4 is arranged between the removal device and the frame;

[0030] A measuring seat 5 is arranged in the frame. The lifting and supporting device is adjusted through this measuring seat to make the axle concentric with the removal device;

[0031] The removal concave fork assembly has a mounting plate 341, and a double concave fork 342 is arranged in front of the mounting plate. Since the concave fork is fixed, the removal is stable; the front and rear double concave forks are set so that the removed axle box is placed in the double forks to prevent random rolling and ensure safety;

[0032] The guiding and moving assembly is a guide rail and guide groove pair 42 driven by a moving oil cylinder 41.

[0033] A nylon sleeve 321 is arranged on the removal oil cylinder piston rod. To prevent damage to the axle box and the piston rod.

[0034] The lifting and supporting device is a common lifting device with a supporting platform arranged on a lift.

[0035] The utility model unloading process is as follows: Figures 3-9 As shown:

[0036] like Figure 3 As shown, the wheelset enters the machine along the workshop track and stops after reaching the predetermined position of the lifting platform;

[0037] like Figure 4 As shown, the left and right unloading devices move toward the center along the linear guide rails, so that the unloading recessed forks reach the predetermined position;

[0038] like Figure 5 As shown, the lifting platform descends, so that the axle of the wheelset is concentric with the top of the unloading device, and at the same time the axle box is stuck into the unloading concave fork;

[0039] like Figure 6 As shown, the piston rods of the unloading cylinders of the left and right unloading devices move forward until they fit the end faces of the axles, and the top ends enter the end holes of the axles to fix the axles;

[0040] like Figure 7 As shown, the left and right withdrawal devices work simultaneously, and the tops on both sides press against the shaft end and move forward until the withdrawal concave fork is withdrawn from the axle box;

[0041] like Figure 8 As shown, the unloading is completed, and the axle box is placed on the nylon sleeve of the oil cylinder piston rod and in the unloading concave fork;

[0042] like Figure 9 As shown, the unloading cylinder is reset and the axle box and wheelset can proceed to the next process.

[0043] 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.
