Embodiment 1

[0026] Embodiment 1 is basically as attached figure 1 Shown:

[0027]The intelligent remote-controlled unmanned trenching machine includes a traveling mechanism 1, which adopts a steel crawler chassis, and the traveling mechanism 1 is connected to the organic platform 2 by rotating a turntable bearing, and the body platform 2 is a rectangular steel plate. The middle position is also fixed with a first drive motor with bolts, the first drive motor drives the body platform 2 to rotate, and the first drive motor adopts the ATS 3306D excavator rotary hydraulic motor reducer assembly. One end of the body platform 2 is fixed with a hydraulic station by bolts, and the other end of the body platform 2 is also hinged with a boom 3, the swing plane of the boom 3 is perpendicular to the body platform 2, and the boom 3 and the body platform 2 are fixedly connected. A driving cylinder 8, the two ends of the first driving cylinder 8 respectively hinge the boom 3 and the body platform 2, an...

Embodiment 2

[0039] Embodiment 2 is substantially the same as Embodiment 1, and the only difference is that the hinge axis of the rotating arm 6 and the end support is parallel to the rotation axis of the cutting disc 12 . When the end support swings, the cutting disc 12 swings left and right around the shaft hinged by the rotating arm 6 and the end support, and the cutting disc 12 can be made perpendicular to the ground by adjusting the swing of the end support, so that the cutting disc 12 is perpendicular to the ground for cutting operations, which is convenient for cutting out Vertically downward groove.

[0040] The outer wall of the fixed bracket is also fixed with a second inclination sensor with screws, which is connected to the controller through RS485 communication. The second inclination sensor also adopts the LCA310T uniaxial voltage output type inclination sensor. The controller collects the signal of the second inclination sensor to obtain the second inclination value of the c...

Embodiment 3

[0044] Embodiment 3 is roughly the same as Embodiment 1, except that the outer wall of the side plate 7 of the end bracket is screwed with an acceleration sensor, the acceleration sensor is connected to the controller through communication, and the acceleration sensor is a Huining S31D02 piezoelectric acceleration sensor. When the cutting disc 12 is excavating, it may hit hard objects, such as stones, hard cement blocks, etc., and the impact teeth constantly hit the hard objects, and the cutting disc 12 will be subjected to a large continuous impact, which can be detected by the acceleration sensor fixed on the end bracket. Measure the impact.

[0045] The controller collects the vibration signal of the acceleration sensor, the analysis module obtains the vibration signal, and monitors the amplitude of the vibration signal, and the frequency threshold and the amplitude threshold are stored in the analysis module. When the amplitude of the vibration signal is greater than the a...

Abstract

The invention relates to the field of engineering machinery, in particular to an intelligent remote-control driverless ditching machine. The technical problem that the position and posture of a cutting disc are difficult to control is solved. The ditching machine comprises a walking mechanism, a ditching machine platform, a movable arm, a bucket rod, a rotating arm, a cutting disc support and a cutting disc. A remote control terminal is used for acquiring control requirements of an operator to obtain a plurality of input signals, the remote control terminal is remotely connected with an analysis module, the analysis module calculates a plurality of control parameters according to the input signals, and the controller controls the travel speed and turning radius of the walking mechanism, the rotation angle of the machine body platform, the rotation angle of the rotating arm, the rotation speed of the cutting disc, the swing angle of the movable arm and the swing angle of the bucket rodaccording to the control parameters. According to the ditching machine, remote control over the ditching machine is realized, the analysis module can calculate the control parameters according to theinput signals, a more intelligent control mode is facilitated, the control difficulty of the operator is simplified, and the operator can easily control and adjust the ditching position of the ditching machine.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an intelligent remote-controlled unmanned ditching machine. Background technique [0002] Ditching machine is one of the main types of construction machinery. It is a ditching machine used in earthwork construction. It is widely used in farmland water conservancy construction, laying of communication cables and pipelines, etc. The functions of the trencher and the excavator have many similarities. They are composed of a traveling chassis, a robotic arm and an end-effector. Both have the functions of entering soil (soil or rock), breaking soil and taking soil. The advantage of the trencher is that it can work continuously, has high construction efficiency, has little damage to the surface, and can excavate trenches with regular shapes, which is especially suitable for laying pipelines. [0003] The Chinese patent with the publication number CN207498793U discloses a ditching c...
