Obviously, the described embodiments are only a part of the embodiments of this utility model, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Embodiments of this utility model provide a device for removing and installing electric wheels for heavy-duty trucks. For example... Figures 1 to 5As shown, the operating device for the electric wheel 500 of a heavy-duty truck includes a lifting fixture 100, a tilting fixture 200, and a supporting fixture 300. The lifting fixture 100 is used to lift the electric wheel 500, for example, to move the vertically positioned electric wheel 500 to another position, i.e., to move the electric wheel 500 from one position to another when its axis is perpendicular to the horizontal. The tilting fixture 200 is used to tilt the electric wheel 500, for example, to tilt the vertically positioned electric wheel 500 to a lying position, or to tilt the lying electric wheel 500 back to a vertical position. That is, an electric wheel whose axis is substantially perpendicular to the horizontal is tilted to a position whose axis is substantially parallel to the horizontal, or vice versa. It is easy to understand that the tilting fixture 200 can also move the lying electric wheel 500. The supporting fixture 300 supports and fixes the electric wheel 500.

[0031] Structurally, such as Figure 1 As shown, the lifting fixture 100 includes a first lifting component and a second lifting component. In the embodiments provided in this application, the first lifting component and the second lifting component may have the same structure. Of course, it is readily understood that the first lifting component and the second lifting component may also have different structures.

[0032] Both the first and second lifting components include a horizontal fixing block 110 and a vertical lifting block 120. The horizontal fixing block 110 is used to fix to the outer frustum 510 of the hub of the electric wheel 500. The vertical lifting block 120 is disposed on the horizontal fixing block 110 and is used for lifting. When applied to the electric wheel 500, as... Figure 2 As shown, the lateral fixing block 110 extends generally along the radial direction of the electric wheel 500, while the vertical lifting block 120 extends generally along the axial direction of the electric wheel 500.

[0033] Specifically, the horizontal fixing block 110 is provided with a first connecting hole 111. The vertical lifting block 120 is fixed, for example, welded to the top surface of the horizontal fixing block 110. Simultaneously, the vertical lifting block 120 is provided with a first lifting hole 121. A first connecting bolt 410 passes through the first connecting hole 111 and the hub bolt hole 511, used to connect the horizontal fixing block 110 to the outer frustum 510 of the hub. The hub bolt hole 511 is a bolt hole provided on the outer frustum 510 of the hub. The first lifting hole 121 is used for the wire rope of the lifting sling to pass through, thereby achieving lifting.

[0034] After installation, a first lifting component and a second lifting component can be installed on the outer truncated cone 510 of the hub of the electric wheel 500. The first lifting component and the second lifting component are symmetrically arranged on the outer truncated cone 510 of the hub. Of course, multiple sets can be installed as needed, such as two sets of first lifting components and second lifting components. These lifting components can be evenly distributed in the circumference of the outer truncated cone 510 of the hub.

[0035] Multiple first connecting holes 111 can be provided on a transverse fixing block 110 for stable connection with the outer frustum 510 of the hub. To facilitate effective matching between the transverse fixing block 110 and the outer frustum 510 of the hub, the inner end face of the transverse fixing block 110 at the end furthest from the vertical lifting block 120 is constructed in an arc shape. This design effectively avoids component interference and allows for arbitrary setting of the number of first connecting holes 111, thereby ensuring connection stability.

[0036] In this application, as Figure 3 and 4 As shown, the flipping fixture 200 includes a first flipping component 210 and a second flipping component 220. The first flipping component 210 includes a first fixing component 211 and a first lifting component 212. The first fixing component 211 is used to fix it to the outer truncated cone 510 of the hub of the electric wheel 500. The first lifting component 212 is connected to the first fixing component 211 and is mainly used in conjunction with slings. The second flipping component 220 includes a second fixing component 221 and a second lifting component 222. The second fixing component 221 is used to fix it to the main support 520 of the electric wheel 500. The second lifting component 222 is connected to the second fixing component 221 and is mainly used in conjunction with slings.

[0037] Specifically, the first fixing member 211 and the first lifting member 212 are integral flat plates. A second connecting hole 213 is provided on the first fixing member 211. Multiple second connecting holes 213 are provided to correspond to the hub bolt holes 511 on the outer truncated cone 510 of the electric wheel 500's hub. A second lifting hole 214 is provided on the first lifting member 212, mainly for the steel wire rope of the lifting sling to pass through. During installation, the first fixing member 211 is parallel to the radial direction of the outer truncated cone 510 of the hub and fits against the outer truncated cone 510 of the hub. Then, a second connecting bolt 420 passes through the second connecting hole 213 and the hub bolt hole 511, thereby connecting the first fixing member 211 to the outer truncated cone 510 of the hub.

[0038] The second fixing member 221 is constructed as a U-shaped groove. A through third connecting hole 223 is provided on the side wall of the U-shaped groove of the second fixing member 221. The second lifting member 222 is fixed to the bottom wall of the U-shaped groove of the second fixing member 221. A third lifting hole 224 is provided on the second lifting member 222. After installation, the U-shaped groove of the second fixing member 221 is engaged with the main bracket 520. At this time, the third connecting hole 223 corresponds to the bracket connecting hole 521 on the main bracket 520. Then, by using the third connecting bolt 430 passing through the third connecting hole 223 and the bracket connecting hole 521, the second fixing member 221 can be set onto the main bracket 520.

[0039] The second lifting member 222 is constructed as a plate-like piece that abuts against the bottom wall of the U-shaped groove of the second fixing member 221. A connecting portion 225 is integrally provided on the second lifting member 222, extending to the side wall of the U-shaped groove of the second fixing member 221. In other words, the second lifting member 222 and the connecting portion 225 are constructed in a U-shaped groove and are snapped onto the second fixing member 221.

[0040] The axial direction of the third connecting hole 223 is perpendicular to the axial direction of the third lifting hole 224. After installation, the first flipping member 210 and the second flipping member 220 are spaced apart on the axial direction of the electric wheel 500, so that the electric wheel 500 can be flipped.

[0041] The support fixture 300 includes a base 310 and a support member (not shown in the figure) protruding from the base 310. The support member is mainly used to support the electric wheel 500 and fix it to the main bracket 520 of the electric wheel 500, so as to erect the electric wheel 500, move it to the working position, or store it.

[0042] The support member is constructed as a rod. An external thread is provided at the free end of the rod. A stepped surface facing the free end is provided on the outer wall of the support member. A lifting cylinder 320 is provided between the support member and the base 310. The extension rod of the lifting cylinder 320 is connected to the support member in a one-to-one correspondence. For example, three sets of circumferentially evenly distributed lifting cylinders 320 and support members are provided on the base 310 to maintain the stability of the electric wheel 500.

[0043] During installation, the hoisted electric wheel 500 is lowered, with the main support 520 of the electric wheel 500 positioned lower than the outer truncated cone 510 of the wheel hub. During descent, the support connection holes 521 on the main support 520 align with the support members, and all support members are inserted into the support connection holes 521. As the electric wheel 500 descends, the main support 520 sits on the landing step surface. At this point, nuts can be tightened on the support members to secure the electric wheel 500 to them. The rod-shaped support members guide the descent of the electric wheel 500 and also support the fixed electric wheel 500. Furthermore, the distance between the electric wheel 500 and the base 310 can be adjusted using the lifting cylinder 320, allowing the support fixture 300 to accommodate electric wheels 500 of different sizes or to meet specific usage requirements.

[0044] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and / or modifications falling within the scope of the present invention, and all changes and / or modifications made according to the embodiments of the present invention should be covered within the protection scope of the present invention.
