[0025] like Figure 1-Figure 4 As shown, a trolley for a mining truck assembly line includes a trolley body 1, a moving structure and a supporting structure;

[0026] The trolley body 1 serves as the main load-bearing structure and can carry a load of ≤20t;

[0027] The mobile structure is installed at the bottom of the trolley body 1 and is used to support the movement of the trolley body 1;

[0028] The support structure is installed above the trolley body 1. The support structure includes a V-shaped elastic component, which is used to automatically fit the support according to the bridge package contour after the trolley body is dropped, and to reset after the trolley body is lifted off.

[0029] In some embodiments, as Figure 1 、 Figure 2 As shown, the mobile structure includes a steel wheel 2, which is mounted on the trolley body 1 through a bearing. The bearing can ensure that the steel wheel 2 can rotate smoothly. The steel wheel 2 is provided with a groove that cooperates with the track of the mining truck assembly line to ensure that the steel wheel 2 moves along the track and the trolley body 1 and the supporting structure move synchronously.

[0030] In some embodiments, as Figure 1 、 Figure 2 As shown, the support structure also includes a transition tooling 3 installed between the trolley body 1 and the V-shaped elastic component. Since it supports the bridge body, the bridge body is higher than the suspension frame, and the height of the trolley itself is not enough to meet the production assembly requirements, so the transition tooling 3 is made to increase the overall height, and also serves to connect the trolley body 1 and the upper V-shaped elastic component.

[0031] In some embodiments, as Figure 1 As shown, the upper end surface of the transition tooling 3 is provided with an oblong hole 31 for installing a V-shaped elastic component, which facilitates adjustment of the installation position of the V-shaped elastic component on the transition tooling 3 to meet the requirements of gear adjustment for different vehicle models.

[0032] In some embodiments, the transition tooling 3 is mounted on the trolley body 1 using bolts, making assembly and disassembly convenient.

[0033] In some embodiments, as Figure 1 、 Figure 2As shown, the V-shaped elastic assembly includes a lower support seat 5 mounted on the trolley body 1, and an upper support seat 4 mounted on the lower support seat 5 and arranged in a V shape;

[0034] Pin shafts 6 are installed at both ends of the upper support seat 4 and the lower support seat 5, and a tension spring 7 is connected to the middle of the upper support seat 4 and the lower support seat 5. The tension spring 7 provides tension for the upper support seat 4 to maintain its posture when it is not working; the upper support seat 4 and the lower support seat 5 are rotated through the pin shaft 6, and the rotation of the upper support seat 4 can achieve fitting support for the axle bridge package.

[0035] In some embodiments, as Figure 1 、 Figure 2 As shown, there are two upper support seats 4 and two lower support seats 5, and the two upper support seats 4 are installed in a V shape on the two lower support seats 5, which changes the original fixed plane support into an adjustable V-shaped support, improves the stability of the mining truck support, and deepens the transformation of the flexible assembly line.

[0036] In some embodiments, as Figure 1 、 Figure 2 As shown, the upper support seat 4 includes a base 41 and a rubber pad 42 installed on the base 41. The base 41 fits with the bridge bag of the bridge body to support the bridge bag, and the rubber pad 42 plays a buffering and protective role to avoid wear on the paint surface of the bridge bag.

[0037] In some embodiments, as Figure 1 As shown, the top of the lower support seat 5 and the bottom of the base 41 in the upper support seat 4 are both provided with triangular connecting plates, and connecting holes are opened on the connecting plates. The pin shaft 6 is installed in the connecting hole so that the upper support seat 4 and the lower support seat 5 can rotate with each other. The structure is simple and meets the use requirements.

[0038] During installation, the steel wheel 2 is installed at the four corners of the trolley body 1 through bearings, and then the transition tooling 3 is installed on the trolley body 1 through bolts. The upper support seat 4 and the lower support seat 5 are pre-assembled together to form a support seat assembly. The lower support seat 5 of the support seat assembly is then installed in the oblong hole 31 of the transition tooling 3 through bolts.

[0039] When using, such as Figure 3 、 Figure 4 As shown, the trolleys are distributed on the line track, the chassis is hoisted and dropped onto the trolleys, the bridge bags of the chassis axles fit with the V-shaped structure on the trolleys, and the trolleys support the chassis by supporting the chassis axles. The chassis is assembled on the line track through the trolleys.

[0040] The utility model relates to a trolley for a mining truck assembly line, which meets the requirements for support and movement of the mining truck body on the mining truck assembly line. The trolley is changed from a fixed plane support to an adjustable V-shaped support. After the mining truck body is installed, the support automatically fits the contour of the bridge package, and automatically resets after the body is lifted off. The support for the bridge package is more closely aligned with the center of gravity, thereby improving the stability of the mining truck support.

[0041] Furthermore, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are also intended to fall within the scope of protection of the present invention and form different embodiments. For example, in the above embodiments, those skilled in the art will be able to use them in combination based on the known technical solutions and the technical problems to be solved by this application.
