Double steel wheel axle and its road roller

Abstract

The invention discloses a double steel wheel vehicle bridge and a road roller thereof, wherein the road roller includes a vehicle body, a front steel cylinder and the double steel wheel vehicle bridge. The front steel cylinder is arranged on the front side of the vehicle body, and the double steel wheel vehicle bridge is arranged among the front steel cylinder, a back steel cylinder and the vehicle body. The double steel wheel vehicle bridge includes a front vehicle bridge and a back vehicle bridge, wherein the front vehicle bridge is connected between the front steel cylinder and the front end of the vehicle body, and the back vehicle bridge is connected between the back steel cylinder and the back end of the vehicle body. The front and back vehicle bridges both include left longitudinalbeams, right longitudinal beams and cross beams, the inner ends of the left longitudinal beams, the right longitudinal beams are connected to the end portion of the vehicle body through a ball hingedstructure. The left longitudinal beams and the right longitudinal beams are telescopic hydraulic cylinders, and a first steel cylinder, a second cylinder and a third cylinder are fixedly arranged on the horizontal side wall of the vehicle body. The first steel cylinder, the second cylinder and the third cylinder are used for winding the telescopic hydraulic cylinders, correspondingly and independently rotate and sleeve the cross beams. A first locking device and a third locking device is correspondingly arranged in the first steel cylinder and the second steel cylinder, wherein a first lockingdevice and a third locking device are used for locking the rotation of the first steel cylinder and the third steel cylinder in the circumferential direction. The lowest points of the first steel cylinder, the second steel cylinder and the third steel cylinder are collinear.

Description

technical field

[0001] The invention relates to the technical field of construction machinery road rollers, in particular to a double-steel wheel axle and a road roller thereof. Background technique

[0002] The road roller, also known as the soil compactor, is a kind of equipment for road construction. Road rollers belong to the category of road equipment in construction machinery. They are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-cohesive and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement layer. With the gravity of the machine itself, the road roller is suitable for various compaction operations, so that the layer to be rolled can be permanently deformed and compacted; while the existing road rollers often need to compact large areas of flat land during on-site construction. When working, the driver ...
