Abstract

The invention discloses a road milling machine and a milling flatness auxiliary control method, which aim at solving a problem that the flatness of the milled road is poor in the prior art. The road milling machine comprises a pressure sensor (4) capable of detecting a walking pressure of the milling machine, wherein a programmable controller (9) and a walking hydraulic pump (8) are arranged on the milling machine (1); the pressure sensor (4) is connected with an input end of the controller (9); a walking hydraulic motor (2) is arranged on a walking crawler (7) of the milling machine; a liquid inlet of the walking hydraulic motor (2) is connected with a walking hydraulic pump (8); and an output end of the controller (9) is connected with a control end of the walking hydraulic pump (8).

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and relates to a road milling machine and an auxiliary control method for milling flatness. Background technique [0002] Road milling machine is one of the main equipment for asphalt pavement maintenance and construction. It is mainly used for the excavation and renovation of asphalt concrete surface. The milling of the wrong table. [0003] At present, during the operation of the road milling machine, the power adaptive method is mainly used to control the output power of the machine: by detecting the engine speed, when the engine speed decreases, the milling machine travel speed is reduced, and when the engine speed increases, the milling machine is increased. Walking speed, always keep the engine speed constant, that is, the engine output power and the machine output power are constant. [0004] This approach is designed to maintain engine power output, maximize machine produ...
