[0029] See Figure 1 , Figure 2 and Figure 3 This utility model provides a multifunctional wheel lifter, comprising:

[0030] Two sets of side beams 1 are provided, and the side beams 1 are equipped with an assembly and reinforcement mechanism. It should be noted that when the rollers 3 or auxiliary wheels 6 are severely worn, it is convenient to disassemble, replace and maintain them, and the overall functionality is good.

[0031] The assembly and reinforcement mechanism includes an assembly base 2, rollers 3, locking nuts 4, assembly base 5, auxiliary wheels 6, connectors 7, and connecting rods 8;

[0032] The mounting base 2 is fixedly installed on the side beam 1 by locking nut 4. The roller 3 is rotatably installed on the mounting base 2. The assembly base 5 is engaged with the side beam 1. The auxiliary wheel 6 is rotatably installed on the assembly base 5. The connecting piece 7 is fixedly installed on the side beam 1. The connecting rod 8 is connected to the connecting piece 7 by bolt pair and positioning pin.

[0033] Through the above-mentioned assembly and reinforcement mechanism, the mounting seat 2 on the roller 3 is fixedly installed on the side beam 1 by the locking nut 4, and the auxiliary wheel 6 is clamped to the side beam 1 by the mounting seat 5. Therefore, when the roller 3 or the auxiliary wheel 6 is severely worn, the locking nut 4 can be removed to remove the roller 3 and the auxiliary wheel 6 from the side beam 1, which is convenient for disassembly, replacement and maintenance. Moreover, the connecting rod 8 is connected to the connecting part 7 by bolt pair and positioning pin. The corresponding length of the connecting rod 8 can be selected according to the railway vehicle with different wheel gauge, which has good functionality.

[0034] Specifically, the assembly and reinforcement mechanism also includes a screw 9, a reinforcement component 10, a washer 11, a steel bar 12, and a second locking nut 14. Each set of side beams 1 consists of two parts. The screw 9 is fixedly installed on one side beam 1. The second locking nut 14 is threaded onto the screw 9. The washer 11 is sleeved on the screw 9. The second locking nut 14 is tightened and fixed to the side beam 1 through the washer 11. The steel bar 12 is fixedly installed on the washer 11. The steel bar 12 is engaged with the reinforcement component 10. The reinforcement component 10 is fixedly installed on one side beam 1 and engaged with the other side beam 1.

[0035] With the above-mentioned assembly and reinforcement mechanism, the screw 9 and the reinforcement 10 are positioned below the side beam 1. The auxiliary wheel 6 supports the wheel, and the supported wheel is positioned above the screw 9 and the reinforcement 10, which will not affect the normal use of the wheel lifter. When the two side beams 1 are joined, the reinforcement 10 can be inserted into one side beam 1. Then, a washer 11 is put on the screw 9, and the washer 11 is rotated to make the steel strip 12 insert into the reinforcement 10. Then, the locking nut 14 is used to lock and fix it, which can improve the overall strength of the two side beams 1 after joining.

[0036] Specifically, the reinforcement 10 has a snap-fit ​​groove 13, and the steel strip 12 is snapped into the snap-fit ​​groove 13. The steel strip 12 is in contact with the side of the side beam 1. It should be noted that this can tighten and limit the reinforcement 10.

[0037] Specifically, a square groove is provided on the side beam 1, and the assembly seat 5 is engaged with the square groove. It should be noted that this facilitates the limiting treatment of the assembly seat 5.

[0038] Specifically, the side beam 1 has a reinforcement hole, the reinforcement part 10 is engaged with the reinforcement hole, and the side beam 1 has a through hole, the screw 9 is in contact with the inner wall of the through hole. It should be noted that this facilitates the assembly and docking of the two side beams 1.

[0039] Specifically, a temperature sensor 15 is fixedly installed on the mounting base 2. The end of the temperature sensor 15 passes through the locking nut 4. The roller 3 has a receiving port, and the detection end of the temperature sensor 15 is located in the receiving port. It should be noted that this allows the temperature of the roller 3 to be monitored. The temperature sensor 15 is connected to an external controller and provides an early warning when the temperature exceeds the set value. The detection end of the temperature sensor 15 is inserted into the roller 3 but does not contact the roller 3, so there is no movement interference between the temperature sensor 15 and the roller 3.

[0040] Working principle:

[0041] S1: Roller 3 is mounted on side beam 1 via mounting base 2 and locking nut 4. Auxiliary wheel 6 is engaged with square groove on side beam 1 via assembly base 5. When roller 3 or auxiliary wheel 6 is worn and needs to be replaced, simply unscrew locking nut 4 to remove roller 3 and auxiliary wheel 6 from side beam 1 for replacement and maintenance. According to railway vehicles with different wheel gauges, select connecting rod 8 of corresponding length and connect connecting rod 8 to connecting part 7 via bolt pair and positioning pin to adjust the overall width of wheel lifter to adapt to different wheel gauges.

[0042] S2: Each set of side beams 1 consists of two parts. During assembly, the reinforcement part 10 is inserted into the reinforcement hole of one of the side beams 1, and then the screw 9 is passed through the through hole on the other side beam 1. The washer 11 is put on, and the washer 11 is rotated so that the steel strip 12 fixed on it is inserted into the snap-fit ​​groove 13 of the reinforcement part 10. Finally, the lock nut 14 is tightened. The two side beams 1 are pressed and fixed by the washer 11, which improves the overall strength of the side beams 1 after docking.

[0043] S3: After completing the above installation and adjustment, move the multi-functional wheel lifter under the railway vehicle whose wheel needs to be lifted. The wheel is lifted in advance by the jack. Roller 3 and auxiliary wheel 6 support and move the wheel lifter. Adjust the position of the wheel lifter so that it can accurately lift the wheel. The structural design of the wheel lifter can ensure its stability and strength to meet the wheel lifting requirements and achieve effective lifting of the railway vehicle wheel for rerailing, maintenance or wheelset replacement and other operations. After completing the rerailing, maintenance or wheelset replacement and other operations, remove the wheel lifter from under the railway vehicle. If roller 3 and auxiliary wheel 6 are found to be worn during use, or if the wheel lifter needs to be adjusted according to the wheel gauge of other railway vehicles, the corresponding maintenance and adjustment operations can be carried out according to the above installation and adjustment steps.
