[0033] 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.

[0034] like Figures 1 to 14 As shown, this utility model discloses a multifunctional wheelset unloading machine 100, including a base 1, an unloading head 2, a material support device 3, a hydraulic system 4, and an electrical control system 5. The material support device is located at one end of the base, and the unloading head is located at the other end of the base. The unloading head has an unloading seat 21, and an unloading cylinder 22 is provided in a groove on the unloading seat. A claw device 25 is provided at one end of the unloading head opposite to the material support device. The material support device 3 has a lower support plate 31, which is connected to a drive assembly 32. A slewing bearing 34 driven by a hydraulic motor D33 is provided on the lower support plate, and an upper support plate 35 is provided on the slewing bearing. The upper support plate is equipped with an axle support frame 37. Guide components 38 are provided between the wheel rim bracket, the axle support frame and the upper support plate, and between the lower support plate and the base. The axle support frame is equipped with a positioning pin A39. The axle support frame is moved according to different axle lengths, and then fixed in place using the positioning pin A39. A positioning pin B04 is provided between the upper and lower support plates and the base. This positioning pin B04 is used when the axle box needs to be fixed in place during removal. The axle support frame is equipped with a V-shaped pad 05 to prevent damage to the axle. A material support device matching the pin and a positioning hole are provided on the base.

[0035] The piston rod of the unloading cylinder is equipped with a pressure head 23 to prevent the axle from becoming too thick.

[0036] The unloading cylinder is equipped with a guide device 24 to ensure the accuracy and stability of the linear movement of the piston rod and to prevent the piston rod from rotating during movement. This guide device is also equipped with a displacement sensor to facilitate the collection of piston rod movement data.

[0037] The pull claw device 25 has a mounting base 251, in which a lead screw and a nut 252 are provided. The lead screw is connected to a hydraulic motor C253, and the pull claw 254 is mounted on the lead screw. The pull claw device is a pair, which are respectively mounted on both sides of the unloading cylinder. The two pull claws are in the shape of facing bearings, and the pull claws are provided with protruding claws that can lock the unloading groove.

[0038] A wheel rim bracket 36 is provided between the two axle support frames, and a nylon support plate 361 for supporting wheels is provided in the wheel rim bracket. A guide assembly is provided between the wheel rim bracket and the upper support plate. This wheel rim bracket is only installed and used when removing the wheel rim.

[0039] An I-shaped platform is provided in the middle of the upper support plate and the axle support frame. When removing the axle box, the platform is fixed with bolts or pins. The axle box is lifted during removal. When removing a general wheelset or wheel rim, the platform is removed.

[0040] The drive component is a hydraulic cylinder device.

[0041] The guiding component is a guide rail and guide groove pair.

[0042] like Figure 7-8 The diagram shown is a process diagram of removing the wheel rim according to this utility model. Figure 7 This is the state before unloading. Figure 8 This is the state after unloading;

[0043] During unloading, the wheel rim is first manually cut apart from the wheel rim, and the wheelset is placed on the material support device so that the wheel enters the wheel rim bracket. Then, the material support device and the claw device are activated so that the claws are locked inside the wheel rim. The unloading cylinder is then activated so that the piston rod presses against the axle and moves forward until the wheel rim is removed and falls onto the wheel rim bracket. After one end is removed, the material support device is rotated 180 degrees and the other end of the wheel rim is removed in the same way. Then, it is lifted away manually.

[0044] like Figure 9-10 The diagram shown is a process flow chart of the unloading of the axle box according to this utility model. Figure 9 This is the state before unloading. Figure 10 This is the state after unloading;

[0045] Use positioning pin B04 to fix the upper and lower support plates and base in place. Install the I-shaped table on the material support device, then insert pins or tighten bolts to align the holes of the axle box with the holes of the I-shaped table to fix them in place. Start the unloading cylinder, and the piston rod will push the axle forward a certain distance to remove the axle box. Remove the pins or bolts, and manually lift the axle away. The unloading of the axle box is now complete.

[0046] like Figure 11-12 The diagram shown is a schematic of the removal of a general wheel according to this utility model. Figure 11 This is the state before unloading. Figure 12 This is the state after unloading;

[0047] Place the wheelset on the axle support frame, then start the material support device and the pull claw device, so that the pull claw is locked on the inner side of the wheel. Then start the unloading cylinder, so that the piston rod head pushes against the axle and moves forward until the wheel is removed. Then rotate 180 degrees and repeat the above operation to remove the other wheel.

[0048] like Figure 13-14 The diagram shown is a schematic of the wheel with unloading groove of this utility model. Figure 13 This is the state before unloading. Figure 14 This is the state after unloading;

[0049] Place the wheelset on the axle support frame, then activate the material support device and the pull claw device to make the pull claw lock in the wheel unloading groove. Then activate the unloading cylinder to make the piston rod press head against the axle and move forward until the wheel is removed. Then rotate 180 degrees and repeat the above operation to remove the other wheel.

[0050] 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.
