Embodiment Construction

[0024] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the vehicle frame anti-wear device 1 of the present invention includes a bracket 11, a shaft coupling 12, a rolling wheel 13, and a bearing 14; wherein

[0025] The bracket 11 includes a plate-shaped base 111, a fixed portion 112 bent at 90° along one side of the base 111, and a pair of side walls 113 and 114 respectively bent and extended along the other opposite sides of the base 111. The walls 113 , 114 and the fixing portion 112 extend opposite to the base 11 , and an accommodating space 110 is formed between the pair of side walls 113 , 114 and the base 111 ;

[0026] Both the base portion 111 and the fixing portion 112 are provided with assembly holes 115 , and the pair of side walls 113 and 114 are provided with coaxial through holes 115 , 116 .

[0027] Coupling 12 penetrates through holes 115 and 116 of bracket 11 and is limited by its assembly. Coupling 12 has a first oil injection hole 122 and ...

Abstract

The invention relates to a wear-preventive device of a frame, comprising a bracket, a coupling shaft and rolling wheels, wherein the coupling shaft and the rolling wheels are arranged on the bracket; and the rolling wheels are sheathed on the coupling shaft and are fixedly arranged at the lower part of the bracket by the coupling shaft. The device is arranged between the frame and a plate spring door seat, so that the direct contact between the plate spring door seat and the frame is avoided. The wear-preventive device is simple in structure, low in production and maintenance cost, easy in replacement and simple in installation on the frame and cannot cause any damage on a frame assembly, thus avoiding the problems of wear and replacement of the frame, reducing the maintenance cost and being applicable to various dump trucks, especially for mine dump trucks.

Description

technical field [0001] The invention belongs to the technical field of dump trucks, and in particular relates to an anti-wear device for a vehicle frame of a dump truck. Background technique [0002] Due to the harsh construction conditions, the performance of construction machinery products used in the mining field has attracted much attention. With the further development of my country's mineral resources development process, the upgrading of construction machinery products used in this field is imminent. In the internal construction of mines, dump trucks are one of the most used products. Traditional dump trucks are no longer suitable for mine construction, and wide-body dump trucks have become the main development direction of mine transportation. [0003] For the construction environment of the mine, which is highly dependent on the performance of the equipment, the reliability of the product is an important aspect. Construction machinery products in the mining field ...
