[0027] The rotating shaft 6 and the rotating shaft base 7 are welded together. The rotating shaft base 7 is fixed to the cross hinge shaft 10 of the fuselage by fasteners. The cross hinge shaft 10 is located at the center of the fuselage hinge plate 9. The rotating shaft 6 is connected to the sleeve 3 through the guide column 4 to ensure coaxiality. The sleeve 3 is connected to the angle sensor 8 through a pin shaft.

[0028] As an improvement of the embodiment, the bottom of the hinge plate flange 5 is a hollow structure, which is used to reserve installation space for the fasteners of the shaft base 7.

[0029] As an improvement of the embodiment, Figure 1 As shown, the upper part of the rotating shaft 6 is a hollow structure for installing the guide column 4, which is connected to the shaft sleeve 3 through the guide column 4 to ensure the coaxiality of the connection. At the same time, the shaft sleeve 3 can slide axially along the guide column 4 to compensate for the assembly error with the angle sensor 8.

[0030] As an improvement of the embodiment, Figure 1 As shown, a protrusion 6-1 is provided on the top of the rotating shaft 6, and a matching groove 3-1 is provided on the bottom of the sleeve 3. The protrusion 6-1 and the groove 3-1 are transitionally matched to avoid mutual radial rotation and improve the accuracy of information transmission.

[0031] As an improvement of the embodiment, Figure 1 As shown, an O-ring 6-2 is installed in the middle of the outer wall of the rotating shaft 6. The O-ring 6-2 is used to block the inner and outer spaces of the hinge plate flange 5 after assembly to prevent the parts from rusting.

[0032] In addition, the fasteners mentioned above may be conventional bolts or the like.

[0033] Finally, the utility model also provides a road roller, on which the angle sensor installation device is installed, such as an unmanned road roller.

[0036] Continue to fix the hinge plate flange 5 to the fuselage hinge plate 9 by bolts;

[0037] Finally, connect the angle sensor 8 to the sleeve 3 through the pin shaft, then place the angle sensor 8 and the sleeve 3 on the base 1, so that the sleeve 3 is correspondingly mounted on the guide column 4, and rotate the angle sensor 8 so that the groove 3-1 on the sleeve 3 is connected and matched with the protrusion 6-1 on the shaft 6.

[0038] When the unmanned roller is installed with the angle sensor installation device, the angle sensor 8, the base flange 2, the hinge plate flange 5 and the rear frame are rigidly connected by bolts; when the front frame turns, the cross articulated shaft 10 rotates with the frame, and the steering information is transmitted through the rotating shaft base 7 and the rotating shaft 6. The rotating shaft 6 and the shaft sleeve 3 are connected by the protrusion 6-1 and the groove 3-1. Finally, the shaft sleeve 3 and the angle sensor 8 are connected by a pin shaft; the joint of the angle sensor 8 rotates with the front frame, and the body of the angle sensor 8 is rigidly connected to the rear frame, thereby realizing the perception of the steering angle of the whole machine.

[0039] The angle sensor installation device of the utility model has a compact overall structure, and the assembled installation is more convenient, saving design space; at the same time, the rotating shaft and the cross articulated shaft are rigid structures, and there is no relative rotation between the rotating shaft and the shaft sleeve, which improves the accuracy of steering information transmission
