Glass fiber reinforced plastic shield assembly of road roller

Abstract

The invention relates to a glass fiber reinforced plastic shield assembly of a road roller. A glass fiber reinforced plastic shield comprises a top plate, two step-shaped side plates, inner mud guards and outer mud guards, the top plate with a high front portion and a low back portion is inclined downwards in a transitional manner by the aid of an arc surface, ladder surfaces on the two side plates are gradually enlarged from front to back, the glass fiber reinforced plastic shield is provided with a diesel engine suction tube slot, radiating holes in the shape of an elongated slot and vent holes, a glass fiber reinforced plastic access door is hinged on a window of one of the side plates, box-shaped rib plates which extend to the inner mud guards and the outer mud guards are further disposed on the lower portion of the glass fiber reinforced plastic shield, metal hinge seats, metal gas spring supports and a metal lock seat which are connected with the glass fiber reinforced plastic shield in an embedded manner are respectively mounted on the glass fiber reinforced plastic shield and connected with a metal support, gas springs and a lock, the metal support is provided with mounting seats which are connected with a frame and disposed at the bottoms of support legs, and metal side plats are disposed on the inner sides of the inner mud guards of the side plates and connected with the metal support. The glass fiber reinforced plastic shield assembly is simple in structure, convenient in assembly and high in practicality, requirements on the rigidity of the shield and the connection reliability can be met, and attractiveness of the integral appearance of the road roller can be enhanced.

Description

technical field [0001] The invention relates to a road roller FRP shield assembly, which belongs to the technical field of road roller FRP shields. Background technique [0002] The protective cover of the road roller is generally arranged at the rear of the cab and installed on the rear frame to effectively control the intrusion of foreign objects, and to block and prevent heat diffusion and diesel engine noise radiation. Because the protective cover occupies nearly one-fifth of the external space of the complete road roller, its appearance directly affects the driving and operating vision and the appearance of the complete machine. All road roller manufacturers pay more attention to its shape design. [0003] At present, the road roller guard has two structures. One is a structural part, which is formed by stamping and forming thin metal materials and then spliced. Due to the high cost of metal materials and production and processing, it has gradually faded out of the mark...

AI Technical Summary

Problems solved by technology

Because the rigidity of FRP is not very good and the shear strength is poor, according to the requirements of use and shape, the shield is generally made into two or three sections of structure, which are installed separately. Not only is the relative cost high, it takes time to debug and install, but the overall effect is not good. During use, especially when the roller breaks down, it is inconvenient to maintain the roller due to the cumbersome loading and unloading of the protective cover.
