[0005] The trolley device has a base plate, a slewing bearing on the base plate, a frame on the slewing bearing, a lifting cylinder in the middle of the frame, a support plate on the lifting cylinder, two symmetrical support shaft assemblies on the support plate, a clamping mechanism on one of the support shaft assemblies, and a guide column for use with the lifting cylinder under the support plate. The trolley device is connected to a moving cylinder, which is located inside the base.

[0006] A guide assembly is provided between the trolley device, the positioning device, and the base.

[0007] The guiding component is a guide rail and guide groove pair.

[0008] The aforementioned support shaft assembly has a set of upright plates, which are axially aligned and have V-shaped support blocks on them, with pads on the support blocks.

[0009] Furthermore, the aforementioned support shaft assembly has two sets of columns, which are placed on the four corners of the trolley device support plate, and the columns are equipped with small column heads.

[0026] 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.

[0027] like Figures 1 to 24As shown, this utility model discloses a wheelset unloading machine, including a base 1, an unloading power head 2, an unloading locking device 3, and a trolley device 4. The unloading power head has an unloading cylinder 21 installed in a mounting base 22. The mounting base is located at one end of the base. The unloading locking device 3 includes a mounting frame 31 and a locking device 32. The mounting frame is provided in front of the mounting base by a horizontal tie rod 311, one end of which is fixed to the mounting base, and the other end is connected to a column 312. One end of the column is fixed to the base. The locking device 32 is an unloading plate 321 with a U-shaped opening facing upwards, which has mounting holes 322. The mounting holes of the unloading plate are fitted with the horizontal tie rod on the mounting frame in front of the unloading power head. The trolley device 4 is located at the other end of the base, corresponding to the unloading power head.

[0028] The trolley device 4 has a base plate 41, a slewing bearing 42 on the base plate, a frame 43 on the slewing bearing, a lifting cylinder 44 in the middle of the frame, a support plate 45 on the lifting cylinder, two symmetrical support shaft assemblies 46 on the support plate, a clamping mechanism 47 on one of the support shaft assemblies, and a guide column 48 for use with the lifting cylinder under the support plate. The trolley device is connected to a moving cylinder 49, which is located inside the base.

[0029] A guide assembly 5 is provided between the trolley device, the positioning device and the base to accommodate wheelsets of different lengths.

[0030] The guiding component is a guide rail and guide groove pair.

[0031] The axle support assembly 46 has a set of upright plates that are axially aligned. The upright plates are provided with V-shaped support blocks, and the support blocks are provided with pads made of nylon to prevent axle damage.

[0032] Furthermore, the aforementioned axle support assembly 46 has two sets of columns, which are placed on the four corners of the trolley device support plate, and small column heads are provided on the columns. This configuration is used when the wheelset has an axle box. The four small column heads cooperate with the positioning holes of the axle box to secure the wheelset to the trolley, so that the axle will not lose balance due to uneven weight distribution after the wheels on one side are removed, thus ensuring smooth removal.

[0033] The process for removing the wheelset in this invention is as follows:

[0034] Before unloading, a nylon transition sleeve is installed on the piston rod of the unloading cylinder;

[0035] like Figure 5-6 As shown, the wheelset is hoisted onto the rotating lifting trolley of the machine, and the trolley clamping mechanism locks the axle.

[0036] like Figure 7-8 As shown, the trolley lifts the wheelset to a certain height;

[0037] like Figure 9-10As shown, the trolley moves the wheelset above the positioning device;

[0038] like Figure 11-12 As shown, the lowering wheelset is placed into the U-shaped opening, at which point the unloading cylinder is concentric with the wheelset;

[0039] like Figure 13-14 As shown, unloading begins, and the piston rod of the unloading cylinder extends and presses against the end face of the axle;

[0040] like Figure 15-16 As shown, the piston rod of the unloading cylinder pushes the axle, the unloading plate blocks the wheel, and the piston rod continues to push the axle;

[0041] like Figure 17-18 As shown, unloading is complete, and the wheel rests on the piston rod transition sleeve;

[0042] like Figures 19-20 As shown, the trolley and piston rod are reset, and the wheel that has fallen onto the outer transition sleeve of the piston rod is lifted away manually.

[0043] like Figure 21-22 As shown, the trolley lifts the wheelset to a certain height;

[0044] like Figure 23-24 As shown, the trolley rotates the other wheel to be removed by 180 degrees, and then repeats the above steps to remove the wheel.

[0045] Similarly, the wheelset removal process with axle box is the same as described above, except that the trolley device is replaced with the corresponding axle support assembly before removing the wheelset.

[0046] 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.
