[0022] The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are intended solely to illustrate the present invention and are not intended to limit the present invention. In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can mean fixed, removable, or integral; mechanical or electrical; direct, indirect through an intermediary, or internal communication between two components. A person of ordinary skill in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. Specific implementation method one:
[0024] like Figure 1 As shown, the utility model provides a locomotive axle box disassembly and assembly device, comprising a support platform 1 and an axle fixing unit, a gear box support unit and an axle box support unit fixed on the support platform 1;
[0025] The axle fixing unit includes two vertical plates 5 arranged relatively spaced apart, with a supporting base plate 7 between the vertical plates 5. To increase friction, the supporting base plate 7 is made of nylon blocks. A horizontal plate 9 is provided on the upper outer side of the vertical plates 5, and a pressure plate 8 is provided above the horizontal plate 9. The pressure plate 8 and the horizontal plate 9 are spaced apart, and each of the horizontal plate 9 and the pressure plate 8 has four circular holes. The horizontal plate 9 and the pressure plate 8 are connected by four adjusting bolts 10 passing through the circular holes, and the adjusting bolts 10 have adjusting nuts.
[0026] The gearbox support unit includes two gearbox support seats 3, each of which has a limit baffle 3-1 on the side facing the vertical plate 5; the surface of the gearbox support seat 3 has a nylon plate for increasing friction;
[0027] The axle box support unit includes an axle box support seat 4 and a bottom plate 11. The bottom plate 11 can be placed directly on the support platform 1 or as shown in FIG. Figure 2 As shown, a slot 18 is provided on the supporting platform, and an inserting block that matches the slot 18 is provided at the bottom of the base plate 11 so that the base plate 11 can be plugged into the supporting platform 1 .
[0028] A plurality of hooks 2 for hoisting the entire equipment are arranged on both sides of the supporting platform 1 .
[0029] Diagonal braces are provided on the outer sides of the vertical plate 5, and reinforcing plates are provided on both sides of the shaft-wrapped support seat.
[0030] When the above structure is used, Figure 2 、 Figure 3 As shown, in order to avoid the gear box 13 colliding with the axle box support seat 4 when hoisting it on the support platform 1, the axle box support seat 4 can be removed from the support platform first, and the gear box 13 pressed together with the axle 14 can be hoisted onto the gear box support seat 3. At this time, the limit baffle 3-1 abuts against one side of the gear box 13 to limit the movement of the gear box 13 in the axial direction, and the tooth end of the axle 14 is placed on the support base 7. The adjusting nut is turned to move the pressure plate 8 downward and clamp the axle 14 together with the support base 7, thereby completing the fixation of the gear box 13 and the axle 14 by the support platform 1. Then, the axle box 15 is passed through the other end of the axle 14, and the axle box support seat 4 is moved to the bottom of the axle box 15 to support it. The contact surface between the gear box 13 and the axle box 15 is fixed with special bolts. Finally, the bearing 16 and the axle box 15 are also fastened with bolts. The disassembly process of the axle box 15 is the opposite of the above process. Specific implementation method 2
[0032] like Figure 4 As shown, based on the structure of the first embodiment, the surface of the support platform 1 has a rectangular first slide 1-1, which is located between the two gear box support seats 3 and penetrates one side of the support platform 1. The bottom of the first slide 1-1 has a slide rail 1-2, and a pull plate 17 is provided in the first slide 1-1. The bottom of the pull plate 17 has a second slide 17-2 adapted to the slide rail 1-2. The pull plate 17 is slidably connected to the first slide 1-1, and the axle box support unit is fixed on the pull plate 17. The pull plate 17 has a handle 17-1. When in use, Figure 5 As shown, before hoisting the gear box 13, a part of the pulling plate 17 is pulled out of the supporting platform 1, so that the axle box support seat 4 on the pulling plate 17 is away from the supporting platform 1. After the gear box 13 is fixed, the axle box 15 is placed on the axle box support seat 4, so that the axle box support seat 4 always follows the axle box 15 and stays close to the gear box 13 during the process of installing the axle box 15 on the gear box 13, so that the axle box support seat 4 forms a supporting force during the entire process of installing the axle box 15.
[0033] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
