[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "back" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] The present embodiment relates to an auxiliary installation device for a rail passenger car empty spring gasket, which can lift the empty spring more labor-savingly, thereby facilitating the addition of a gasket under the empty spring.

[0025] Based on the above design concept, an exemplary structure of the auxiliary installation device for the rail passenger car empty spring gasket of this embodiment is as follows: Figure 1-2As shown, it mainly includes an empty spring support column 1, a jack 3, a nylon bushing 2 and a support frame 4. The empty spring support column 1 includes a main support column 101 and a connecting column 102; the main support column 101 and the jack 3 are respectively connected above and below the connecting column 102; the nylon bushing 2 is mounted on the main support column 101; and the jack 3 is placed on the support frame 4.

[0026] Specifically, the size and shape of the nylon bushing 2 match the size of the empty spring hole left below the support column and the vehicle body bogie, so as to facilitate fixing the support column in the exact center of the empty spring hole.

[0027] A groove is provided under the connecting column 102, and the top of the jack 3 is installed in the groove; the main support column 101 and the connecting column 102 are both cylindrical; the axis of the main support column 101 and the axis of the connecting column 102 are on the same straight line, and the main support column 101 and the connecting column 102 are fixedly connected.

[0028] The support frame 4 is I-shaped. It can be understood that the bottom of the support frame 4 can be provided with lockable universal wheels to facilitate adapting to different installation environments and improve the adaptability of the device. The height of the support frame 4 can be set according to actual needs.

[0029] When the auxiliary installation device for the empty spring gasket of a railway passenger car described in this embodiment is used, the jack 3 is placed on the I-shaped support frame 4, and the groove below the connecting column 102 is aligned with the top of the jack 3. The groove of the connecting column 102 can clamp the top of the jack 3, and the nylon bushing 2 is put on the main support column 101. The main support column 101 is inserted upward from the empty spring hole left below the car body bogie, and the main support column 101 is fixed at the center of the empty spring hole with the nylon bushing 2. The jack 3 is pressed to lift the empty spring upward to increase the gap between the empty spring and the bogie, and the empty spring gasket is put in. After fixing it, the jack 3 is released, the empty spring is dropped, and the components are taken out from the bottom.

[0030] The railway passenger car empty spring gasket auxiliary installation device using the above implementation scheme can effectively realize the effortless lifting of the empty spring, thereby facilitating the addition of gaskets under the empty spring. The device has a simple structure, is easy to move, and is safer, more convenient and labor-saving when adding empty spring gaskets.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
