[0002] Under the traditional operation mode, in order to ensure that the axle box arm is in the appropriate position to cooperate with the bogie frame installation, the maintenance personnel have to adopt the method of manually supporting the axle box arm with a scaffold. This method has many drawbacks. First of all, the human consumption is huge. Long time maintaining the same posture to support the axle box arm can easily lead to worker fatigue, which not only reduces the work efficiency, but also increases the risk of human error. Moreover, the safety of manual support of the axle box arm cannot be effectively guaranteed. In the process of hoisting and landing of the bogie frame, once the hoisting equipment fails or the frame shakes, the life safety of the operating personnel will be seriously threatened.

[0003] At the same time, manual support cannot guarantee the accuracy of the position and angle of the axle box arm each time, which has an adverse effect on the installation quality of the bogie frame, and may further lead to abnormal vibration of the rail vehicle during operation, aggravation of component wear and tear, etc., increasing the vehicle failure rate and shortening the service life of the vehicle. In addition, due to the lack of effective buffer and shock absorption measures, the vibration and impact force generated during vehicle operation will directly act on components such as axle box arm and bogie frame, accelerating the damage of components and increasing maintenance cost and maintenance workload. In view of the various defects of the traditional method, it is urgent to develop an innovative tool to solve the problem of axle box arm support and improve the efficiency, safety and quality of rail vehicle maintenance operation.

[0016] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict.

[0017] In the description of the application, it should be noted that the terms "upper", "lower", "inner", "back" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0018] The application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0019] The embodiment relates to a device for supporting a railcar axle box arm, which can replace manual support of the axle box arm. Based on the design idea, an exemplary structure of the device for supporting the railcar axle box arm is shown in the figure, which mainly comprises a base 6, a support beam 4 connected above the base 6, and a U-shaped frame 3 arranged at the top of the support beam 4. Figs. 1-2 The base 6 comprises a rectangular block and a threaded sleeve, the threaded sleeve is horizontally arranged above the rectangular block, and the threaded sleeve and the rectangular block are integrally formed, a connecting rod 5 is arranged between the two threaded sleeves, and the connecting rod 5 is a threaded rod.

[0020] Based on the foregoing, the rectangular block part of the base 6 is cut and processed from a thick steel plate, so as to ensure sufficient quality and stability, the threaded sleeve is integrally formed with the rectangular block through a casting process, the inner diameter of the threaded sleeve matches the outer diameter of the threaded rod of the connecting rod 5, so as to ensure that the connecting rod 5 can be smoothly installed between the two threaded sleeves, and the size of the base 6 as a whole can be adjusted by rotating the connecting rod 5, so as to adapt to different installation conditions and fine adjustment requirements of the stability of the support device.

[0021] Specifically, the U-shaped frame 3, the support beam 4 and the base 6 are welded together.

[0022] It can be understood that the U-shaped frame 3 is provided with a rubber plate with the same shape as the U-shaped frame 3, so as to facilitate protection and prevent bumping.

[0023] When the device for supporting the railcar axle box arm is used, first, the bogie 1 maintenance installation area is cleaned at the rail vehicle maintenance operation site, so as to ensure that the ground is flat and free of sundries. Meanwhile, whether all parts of the tooling are intact is checked, such as whether the rubber plate on the U-shaped frame 3 is detached, whether the connecting rod can be smoothly rotated and the like. The parts of the tooling are transported to the vicinity of the installation area and are placed according to the installation order, so as to facilitate subsequent assembly operation.

[0024] Subsequently, the prepared base 6 is placed at the position planned in advance below the rail vehicle bogie 1. Then, the connecting rod 5 is slowly screwed into the two threaded sleeves of the base, the connecting rod is rotated by using a wrench or the like, the base is adjusted to a proper tightness according to actual installation requirements, and the compactness and stability of the overall structure of the base are ensured.

[0025] When bogie 1 is hoisted by the lifting equipment to the position above the installation position, the operator aligns the position of axle box arm 2 to U-shaped frame 3. With the slow landing of bogie 1, axle box arm 2 gradually approaches U-shaped frame 3. When the bottom of axle box arm 2 contacts the rubber plate on U-shaped frame 3, the operator slightly adjusts the position of bogie 1 to ensure that axle box arm 2 can be placed in the center position of U-shaped frame 3 stably and fully contacts the rubber plate. During the whole process, the operator can ensure the placement accuracy of axle box arm 3 by observing the relative position of axle box arm 2 and U-shaped frame 3 and using some auxiliary measuring tools such as a level meter.

[0026] After axle box arm 2 is placed on U-shaped frame 3, it is checked again whether each component of the tooling is firmly connected and whether connecting rod 5 has a loosening phenomenon. At the same time, the contact between axle box arm 2 and U-shaped frame 3 is checked to ensure that the rubber plate can effectively play a buffering and anti-skid role. If any abnormality is found, timely adjustment and repair are carried out.

[0027] The device for supporting the axle box arm of the rail passenger car adopting the above-mentioned implementation solution can effectively replace manual support of the axle box arm during the installation process of the bogie frame of the rail vehicle, not only reduces the workload of personnel and improves the installation efficiency, but also greatly reduces the safety risk in the operation process, and ensures the smooth progress of the repair operation of the rail vehicle.

[0028] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
