Road roller vibrating wheel and road roller

Abstract

The invention discloses a road roller vibrating wheel. The vibrating wheel comprises a wheel body which can be rolled, a shock absorber and a left vibration exciter, an intermediate vibration exciter and a right vibration exciter which are coaxially arranged on an intermediate transmission shaft in sequence, and the left vibration exciter, the intermediate vibration exciter and the right vibration exciter are arranged in the wheel body through vibration bearings respectively and are driven by a power device to rotate; the intermediate vibration exciter is connected with the left vibration exciter through a multi-gear power shifting gear speed change mechanism, and the left vibration exciter is directly connected with the right vibration exciter through the intermediate transmission shaft. The invention further discloses a road roller containing the road roller vibrating wheel. According to the road roller vibrating wheel and the road roller, the multi-gear power shifting gear speed change mechanism is adopted, when the road roller vibrating wheel is located at different gears, multiple types of position interrelations are formed among the left vibration exciter, the intermediate vibration exciter and the right vibration exciter, switching can be conducted between the circumferential vibration mode and the vertical vibration mode at any moment, vibration intensity of circumferential vibration can be adjusted at any moment, the application range of the vibratory road roller is expanded, and more types of construction conditions are satisfied.

Description

technical field [0001] The invention relates to a road roller, in particular to a road roller vibrating wheel and a road roller capable of switching the vibration mode and adjusting the vibration intensity. Background technique [0002] The road roller is a construction machine whose main purpose is to increase the compactness of the working medium (earth filling and road pavement mixture). The earliest road rollers were compacted by static force, that is, the static pressure generated by the weight of the road roller was used to force the working medium to be dense. The internal friction between the particles is lost, resulting in higher compaction efficiency and better compaction effect, so vibratory rollers are gradually becoming mainstream. [0003] The vibrating wheel is one of the key components of the vibratory roller. It is not only the working device of the vibratory roller, but also the traveling device of the vibratory roller. Among them, the vibrating wheel dri...

Problems solved by technology

[0004] Existing vibratory rollers can be divided into circular vibratory rollers, vibratory vibratory rollers, and vertical vibratory rollers according to different vibration modes. According to different construction conditions, the vibration mode and vibration intensity can be adjusted at will to meet the different requirements of various compaction conditions for the vibrating wheel of the road roller, so the application range is narrow and the construction efficiency is low.

[0005] For example, the vibrating wheel of a typical vertical vibratory road roller includes a rollable steel wheel, a shock absorber, and a left vibrator, a middle vibrator and a right vibrator coaxially arranged on the middle transmission shaft in turn, the left vibrator, The middle vibrator and the right vibrator are respectively set in the steel wheel through vibration bearings and rotated under the drive of the power device. The middle vibrator is connected with the left vibrator through a reversing gear transmission mechanism, and the left vibrator and The right vibrator is directly connected through the transmission shaft, so that the left and right vibrators rotate in the same direction synchronously, and the middle vibrator and the left vibrator rotate in the opposite direction synchronously. Obviously, in the above vibration mode, the three exciters The mutual relationship between the rotation positions of the device is uniquely determined, and only vertical vibration can be realized and other vibration modes cannot be realized. The vibration mode is unique and cannot be adjusted.
