Safety protection device on road roller

Abstract

The invention discloses a safety protection device on a road roller. The safety protection device comprises a supporting frame and a shield, wherein the supporting frame is composed of two bilaterally symmetrically arranged supporting tubes and a plurality of connecting tube for connecting the two supporting tubes, the upper part of the supporting frame is covered with the shield, the left and right sides of the shield are respectively correspondingly welded with the supporting tubes on the left and right sides, each supporting tube is of a U-shaped structure composed of a back tube section, an upper tube section and a front tube section, a connecting plate is welded between the back tube sections of the two supporting tubes, a plurality of insert columns are also arranged below the connecting plate, a backing plate is welded at the bottom of the front tube section of each of the two supporting tubes, and connecting holes are formed in both the connecting plate and the backing plate. The supporting tubes on two sides and the shield of the safety protection device are in an integrated structure instead of being formed by welding, so the safety protection device has high strength, avoids the problem of easy oxidation corrosion at the connections resulted from the traditionally adopted welding manner, is difficult to accumulate liquid, has high structural strength and has high connection firmness with an outer casing on the road roller.

Description

【Technical Field】 [0001] The invention relates to the technical field of parts of road rollers, in particular to a safety protection device on a road roller. 【Background technique】 [0002] Road rollers belong to the category of road equipment in construction machinery. They are widely used in filling compaction operations of high-grade highways, railways, airport runways, dams, stadiums and other large engineering projects. They can roll sandy, semi-cohesive and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement layer. The roller is suitable for various compaction operations by the gravity of the machine itself, so that the compacted layer will be permanently deformed and compact. Safety protection devices are usually installed on the road roller to protect the electrical equipment in the cockpit of the road roller from the sun and rain, and also to protect the personal safety of the driver. The current cockpit frame is usually welded by large and small pip...
