Vehicle-mounted navigation system mounting structure and engineering machine

Abstract

The invention discloses a vehicle-mounted navigation system mounting structure and an engineering machine, and belongs to the field of engineering machinery. The mounting structure comprises a vehicle-mounted navigation system and a mounting seat, wherein the vehicle-mounted navigation system comprises a radio station and a GNNS receiver, the GNNS receiver is internally provided with a directionalantenna and a positioning antenna, the mounting seat is provided with a mounting surface which is higher than the top of a vehicle, the mounting surface is provided with through holes for wiring, theradio station and the GNNS receiver are both fixedly mounted on the mounting surface, and wiring harnesses undergo wiring through the through holes. According to the mounting structure and the engineering machine, the directional antenna and the positioning antenna are arranged inside the GNNS receiver, other objects can be prevented from mistakenly touching the directional antenna and the positioning antenna, the installation process is simplified, the horizontal height of the whole mounting seat is low, the horizontal shaking amplitude of the vehicle-mounted navigation system can be reduced, the navigation precision is improved, the vehicle-mounted navigation system is mounted at the top of a cab and is closer to an electric control cabinet in the cab, the wiring length can be reduced,and the cost is reduced. The invention further discloses the engineering machine using the mounting structure.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an installation structure of a vehicle navigation system and an engineering machinery. Background technique [0002] At present, the commonly used installation methods for excavator antennas (including positioning and directional antennas) and GNNS receivers are to install the positioning and directional antennas at the two ends of the rear of the excavator counterweight parts respectively, in order to avoid engine protection. The hood blocks its receiving signal. Generally, a cylindrical bracket is used to raise the positioning and directional antenna respectively, higher than the occluder, and the bottom of the cylindrical bracket is fixed on the counterweight panel through threaded holes and bolts. The radio antenna is installed on the roof of the cab, and the GNNS receiver is installed in the electric control cabinet inside the cab. The above-mentioned positioning antenn...

AI Technical Summary

Problems solved by technology

[0003] There are other components installed around the counterweight components. The positioning and directional antennas are respectively installed at both ends of the back of the excavator’s counterweight, which is easy to touch nearby objects and cause damage; the positioning and directional antennas are far away from the electric control cabinet in the cab. , increase the difficulty of wiring, increase the length and complexity of wiring at the same time, which is not conducive to saving costs; longer cylindrical support frames and wiring harnesses increase installation costs; when the excavator is working, the whole machine will produce severe vibrations. The support frame will inevitably increase the level of vibration of the antenna's horizontal position, thereby reducing the positioning and orientation accuracy
