Automobile crane top-mounted electrification control system

Abstract

The invention discloses an automobile crane top-mounted electrification control system. The system comprises an engine arranged on an automobile chassis and a gearbox connected with an output shaft ofan engine through a clutch, the output shaft of the engine is connected with an input shaft of a generator through a transmission mechanism, the output end of the generator is connected with a top-mounted motor through a direct-current voltage stabilizer and an inverter sequentially, the top-mounted motor is used for performing power supply driving on a winch rotating mechanism and a lifting armhydraulic system, the output end of the generator is connected with the input end of a chassis motor, and the output end of the chassis motor is in driving connection with a force taking oil pump of asupporting leg. According to the system, a top-mounted engine structure is cancelled, so that the weight of the whole crane is reduced, moreover, the generator is used for supplying power to the motors, so that electrification driving of the crane is realized.

Description

technical field [0001] The invention relates to the field of automobile crane control systems, in particular to an electrified control system for automobile crane bodywork. Background technique [0002] The current truck cranes mostly adopt a dual-engine configuration, that is, a chassis engine and a top-mounted engine are installed. The chassis engine drives the travel, and the top-mounted engine drives the hydraulic system to drive the boom for hoisting operations. With the upgrading of national environmental protection requirements on construction machinery emissions, the emission limits for crane exhaust pollutants have been tightened. The engine exhaust system on the crane needs to be equipped with after-treatment devices, including urea pumps, urea tanks and other parts. It is large and heavy, which increases the fuel consumption of the whole machine, and it is difficult to arrange it in the limited space of the bodywork, and it needs regular maintenance and high cost....

Problems solved by technology

With the upgrading of national environmental protection requirements on construction machinery emissions, the emission limits for crane exhaust pollutants have been tightened. The engine exhaust system on the crane needs to be equipped with after-treatment devices, including urea pumps, urea tanks and other parts. Large and heavy, which increases the fuel consumption of the whole machine, and it is difficult to arrange in the limited space of the bodywork, and requires regular maintenance, which is costly

Moreover, the bodywork engine and accessory power system are arranged around the control room of the vehicle, so the noise is loud during the hoisting operation, and long-term work will cause the operator's physical discomfort
