Road roller

Abstract

The invention provides a road roller. The road roller comprises a rolling wheel, a chassis, a cab, a rotation driving device, a travelling driving device, a rotation switch and a controller. A seat and an operation device are arranged in the cab. The rotation driving device is used for driving the cab to rotate. The travelling driving device is used for driving the rolling wheel to rotate in the preset rotation direction according to a first operation command of the operation device so as to make the road roller travel in the preset travelling direction. The rotation switch can generate a rotation control signal when triggered so as to control the rotation driving device to drive the cab to rotate. The controller is used for controlling the travelling driving device to drive the rolling wheel to rotate in the direction opposite to the preset rotation direction according to the first operation command of the operation device when the seat rotates to a preset angle range, so that the road roller travels in the direction opposite to the preset travelling direction. According to the road roller, due to the fact that the direction of the seat is consistent with the travelling direction of the road roller, a driver does not need to twist the neck to observe the road conditions in the roller advancing direction during driving, and the driving experience is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a road roller. Background technique [0002] During the construction of asphalt pavement, the double-drum road roller is a compaction equipment that must be configured. Its purpose is to compact the asphalt layer through the vibration of the steel wheel, so as to achieve the compactness and flatness required by the national standard. According to the requirements of the construction process, in order to ensure that the asphalt is compacted within the most suitable temperature range, the double-drum roller generally follows the paver for construction, and generally requires 3-4 back and forth reciprocating compactions to compact the road section. The length is generally about 50-100m. It can be seen that the double drum roller needs to perform reciprocating motion during the compaction operation. When moving forward, the driver needs to check the front view of the machine, an...

AI Technical Summary

Problems solved by technology

It can be seen that the double drum roller needs to perform reciprocating motion during the compaction operation. When moving forward, the driver needs to check the front view of the machine, and when retreating, the driver needs to check the rear view of the machine. However, in the current industry Double-drum vibratory rollers use the method of rotating the seat 70 degrees or 90 degrees left and right to solve this problem, that is, when the roller is moving forward, the driver turns his head to the left to look at it, and when the roller is backing up, the driver turns his head to the right to look at both. The front and the rear view are also taken into account. However, in this way, the driver needs to twist his neck all the time during the construction process, which makes the driver prone to fatigue. After 8-12 hours of construction, the neck of the cab is often sore and stiff. , which is seriously inconsistent with ergonomic standards

In addition, when the double-drum roller is in normal construction, the driver's seat is rotated 90 degrees to face the side of the machine, and there is a blind spot behind the driver. There are many people on the asphalt road construction site, especially at night, which poses a great safety hazard
