Description

Technical Field:

[0001] The present application relates to the technical field of construction machinery, and particularly to a mudguard mounting structure for off-road mining dump trucks. Background Art:

[0002] An off-road mining dump truck is a special load-carrying vehicle used for short-distance transportation to complete the tasks of rock and soil stripping and ore transportation on special roads such as open-pit mines or large-scale civil engineering sites. It has the characteristics of large load and external dimensions, and complex and changeable road conditions.

[0003] For the mudguard of the front wheels of an off-road mining dump truck, in order to play a role in preventing mud without interfering with the tires, there is a certain gap between the mudguard and the tires. Therefore, the mudguard mounting bracket is usually a cantilever structure, especially the mudguard mounting bracket on the rear side of the platform has a long cantilever. Due to the complex and changeable road conditions and large vibrations during the driving of off-road mining dump trucks, the mudguard mounting bracket is prone to deformation or fracture. Utility Model Content:

[0004] To solve the above technical problems, the present utility model provides a mudguard mounting structure for off-road mining dump trucks, and the technical problem to be solved is that the mudguards of the front wheels of off-road mining dump trucks are prone to deformation or fracture. The technical solution adopted by the present utility model to solve the above technical problems is as follows:

[0005] A mudguard mounting structure for an off-road mining dump truck, comprising:

[0006] An upper baffle connected to the frame crossbeam in a fixed structure manner, and a reinforcing rod connecting the platform is fixedly arranged on the upper baffle;

[0007] An inclined plate fixedly connected to the upper baffle;

[0008] Support rods, with both ends of the support rods fixedly connected to the inclined plate and the upper baffle respectively, and a preset number of support rods are arranged in parallel at intervals;

[0009] A lower baffle, with the upper part of the lower baffle connected to the lower part of the inclined plate.

[0010] Furthermore, frames are fixedly arranged on the inner sides of the upper baffle and the inclined plate, and the frames are arranged in a square-grid structure.

[0011] Furthermore, both ends of the reinforcing rod are connected to the upper baffle and the side elevation of the platform through bolts, and gaskets are sleeved outside the bolts.

[0012] Furthermore, the lower baffle is a rubber sheet with cloth layers.

[0013] Further, a backing plate is provided on the side of the lower baffle away from the inclined plate, and the backing plate, the lower baffle, and the inclined plate are sequentially connected by bolts.

[0014] The beneficial effects of the present utility model are as follows: One end of the upper baffle is fixed at the cross beam of the frame of the non-road mining dump truck, and the upper baffle is connected to the platform by using a reinforcing rod. The installation position is reasonably arranged, and a support rod is fixed between the inclined plate and the upper baffle. Without affecting the existing structure, the strength and stiffness of the mudguard are improved, the replacement frequency of the mudguard is reduced, and the service life is extended.

[0015] Through the setting of the frame-shear wall, while meeting the lightweight design, the support stiffness of the mudguard is ensured. Description of the drawings:
