Abstract
Description
Technical Field
[0001] The utility model relates to the field of disassembly and assembly of automobile rear axles, in particular to a device for disassembly and assembly of mining automobile rear axles. Background Art
[0002] When disassembling the rear axle of the D32 mining dump truck / car, it is necessary to use an overhead crane to lift the car body, remove the connecting bolts, use the forklift to extend the arm to lift the rear axle bumper, and connect it with a wire rope. Workers use crowbars to pry the tires on both sides, and the forklift cooperates to drag the rear axle to move. During the whole process, the forklift must move synchronously with the rear axle and keep the left and right moving speeds consistent. When installing the rear axle, the forklift needs to hold up the rear axle, and the workers move the wheels forward at the same time. The forklift adjusts the position of the rear axle left and right and up and down to align the rear axle seat holes.
[0003] The existing method of disassembling and assembling the rear axle of mining vehicles has certain shortcomings. First, during the entire maintenance process, a forklift is used to cooperate with workers to move the rear axle forward and backward. If the speed of the forklift moving forward and backward is inconsistent with the speed of prying the tire, the connection between the forklift and the rear axle will fall off, causing the rear axle to flip and cause danger. Secondly, when aligning the seat hole, if the forklift is not adjusted accurately to the left and right, the seat hole cannot be aligned, and repeated tests are required, which prolongs the maintenance time. Finally, during the maintenance process, more than 6 operators are required, which increases the risk factors. Utility Model Content

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0025] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0027] The utility model provides a technical solution: a device for disassembling and assembling the rear axle of a mining vehicle, such as Figure 1 and Figure 2 As shown, it includes a bracket head 1, and a card slot 11 is provided on the bracket head. The front view of the bracket head 1 is concave. The lower surface of the bracket head 1 is connected to the upper surface of the bracket 2, and the lower surface of the bracket 2 is connected to the upper surface of the support plate 3. The support plate 3 is rectangular, and the four corners of the lower surface of the support plate 3 are respectively connected to the upper surface of a support column 4, the lower surfaces of the two front support columns 4 are connected through the front upper slide rail 5, and the lower surfaces of the two rear support columns are connected through the rear upper slide rail 6. The front upper slide rail 5 is slidably connected to the upper part of the front scissors frame 7, and the rear upper slide rail 6 is slidably connected to the upper part of the rear scissors frame 8. The lower part of the front scissors frame 7 is slidably connected to the front lower slide rail 9, and the lower part of the rear scissors frame 8 is slidably connected to the rear lower slide rail 10. Pulleys are provided at the lower parts of the front lower slide rail 9 and the rear lower slide rail 10. The pulleys are made of nylon material with a diameter of 100mm and can bear a weight of 2T.

[0029] The working mode of the utility model is as follows:
[0030] Rear axle removal: After removing the rear axle connector (large transmission shaft, rear wheel tire, A-frame, rear axle stabilizer bar, etc.), push the utility model into the rear axle bumper. Raise the jack 12, so that the jack 12 lifts the support plate 3, drives the front scissor frame 7, the rear scissor frame 8, the bracket 2 and the bracket head 1 upward, and makes the card slot 11 snap into the rear axle bumper, which can prevent the tool from being separated from the rear axle and causing the rear axle to flip over. After the vehicle body is fixed, use a forklift or a person to drag the rear axle. The utility model can move simultaneously with the rear axle and keep the rear axle balanced, so that the rear axle can be safely dragged out.
[0031] Install the rear axle: place the rear axle in the slot 11, push the lower rail, push the whole device to the bumper, adjust the height of the jack 12, move the slot 11 up and down to align the rear axle with the seat hole, and install the rear axle connecting pin and fixing bolts. After the installation is completed, lower the jack 12 to remove the device.
