Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings. like Figure 1-4 As shown, the present invention is mainly applied to mine dump trucks, especially heavy-duty mine dump trucks for large mines. During the operation of the mining dump truck, the vibration from the engine and the road surface is very large; under acceleration, turning and other working conditions, the fixing bolts are subjected to a large shear force. As a preferred embodiment, a cab fixing structure of a mining dump truck includes a base 1, a fixing bracket 2, an upper rubber support block 3, a lower rubber support block 4, a pressure plate 5, bolts 6, nuts 7 and washers 8 ; The base 1 is welded on the bottom of the cab 10, and is provided with a plurality of square holes 12 arranged in an L shape; the fixed bracket 2 is welded on the vehicle frame, and an L-shaped stop 11 is arranged on it The bottom of the upper rubber support block 3 and the top of ...

Abstract

The invention discloses a cab fixing structure of a self-dumping truck for mines. The cab fixing structure comprises a base, a fixing support frame, an upper rubber support block, a lower rubber support block and a press plate, wherein the base is provided with a plurality of square holes, the square holes are in L-shaped arrangement, an L-shaped stop opening is arranged in the fixing support frame, and the upper rubber support block, the base, the lower rubber support block and the fixing support frame are sequentially arranged under the press plate and are connected into a whole with the press plate through screw bolts, screw nuts and gaskets. The cab base is arranged between the two rubber support blocks, so the shock absorption effect is respectively realized during the vertical moving, in addition, the total thickness of rubber is very great, and the shock absorption effect in the vertical direction is obvious. Meanwhile, rubber pads are designed, so the screw bolts are not in direct contact with the base, the generation of rigid impact is prevented, and the shock absorption is stilled realized in the horizontal direction. The cab fixing structure has the advantages that when the L-shaped stop opening is in direct contact with the lateral surface of the base, the auxiliary position limiting effect can be realized, the shearing force born by the screw bolts is reduced, and the service lives of the screw bolts are prolonged.

Description

technical field [0001] The invention relates to a mining dump truck cab, in particular to a mining dump truck cab fixing structure. Background technique [0002] With the increase in mining operation and output of large-scale open-pit coal mines, iron ore, and copper mines, and the large-scale construction of water conservancy projects increasing year by year, large-tonnage mining dump trucks have been widely used in large-scale open-pit mine transportation and water conservancy project construction. The vibration generated by the giant engine of the large-tonnage mining dump truck is also becoming more and more obvious. In addition, the roads during transportation are mostly temporarily paved gravel roads, and the road conditions are very bad. It is necessary to ensure the driver's comfortable work and physical and mental health. It is possible to prevent premature damage to the cab fixing bolts and affect the shock absorption effect, which requires the cab fixing structure...
