Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0012] like Figure 1-3 The device shown is a bucket wheel excavator rotation detection device, comprising: a gear 1, a gear shaft 2, a first connecting device, a support frame, an encoder 3, a second connecting device, a coupling 4, a reducer 5, and bolts 6; the encoder 3 and the reducer 5 are located inside the support frame, with the encoder 3 positioned above the reducer 5, and the encoder 3 and reducer 5 connected together by the coupling 4 and transitionally connected by the second connecting device; the bottom of the support frame is connected to the first connecting device by bolts 6, the gear shaft 2 is connected to the first connecting device with one end connected to the reducer 5, and the other end passes through the first connecting device and connects to the gear 1; The gear 1 is provided with a large gear ring that meshes with it. The large gear ring is connected to the power device. The power device drives the large gear ring to rotate, which in turn drives the gear 1 to rotate accordingly. The support frame includes a base plate 7 and two side plates 8 perpendicular to the base plate 7. The two side plates 8 are vertically arranged at both ends of the base plate 7 and together with the base plate 7 form an internal cavity for accommodating the encoder 3 and the reducer 5. The tops of the two side plates 8 are welded and fixed to the bucket wheel excavator equipment. Furthermore, the encoder 3 is fixedly connected above the second connecting device by bolts 6. The second connecting device includes a horizontal plate 9 and two vertical plates 10 perpendicular to the lower end face of the horizontal plate 9. A gap is set between the two vertical plates 10, and a coupling 4 is set in the gap space. The coupling 4 connects the encoder rotating shaft to the reducer output shaft; The base plate 7 of the support frame has a through hole 7.1 for the gear shaft 2 to pass through; The gear shaft 2 has a square shape; one end of the gear shaft 2 where the gear 1 is mounted is the input end, and the other end is the output end of the gear shaft. The output end of the gear shaft is connected to the input shaft of the reducer through a square sleeve 15; the square sleeve 15 acts as a coupling. The upper and lower ends of the first connecting device, corresponding to the position of the support frame through hole 7.1, are also provided with through holes for the gear shaft 2 to pass through; the first connecting device is formed by a top plate 11, a bottom plate 12, and two vertical plates 13 connected between the top plate 11 and the bottom plate 12. The top plate 11 has an upper through hole, and the bottom plate 12 has a lower through hole; the gear shaft 2 is engaged with the upper and lower through holes through a bushing 14. The lower end face of the support frame base plate 7 is provided with a stop that matches the top plate 11 of the first connecting device. The top plate 11 of the first connecting device is installed at the stop position of the support frame base plate 7 and fixed together at both ends by bolts 6. The stop facilitates accurate positioning of the first connecting device and the support frame and makes installation convenient. The gear shaft 2 extends to the position below the base plate 12 of the first connecting device, where it is connected to the gear 1 by a key and locked at the end of the gear shaft 2 by a nut 16 and a washer 17.

[0013] Based on the above scheme, the module of gear 1 is the same as the module of the large gear ring that it meshes with.

[0014] Based on the above structure of this scheme, the power unit drives the large gear ring to move, and gear 1 rotates together with the large gear ring to perform driven motion; every time gear 1 rotates by an angle, it is transmitted to encoder 3 through speed change via reducer 5 for output; by adding reducer 5 between gear 1 and encoder 3, the problem of inaccurate encoder calculation when directly transmitting data is solved, and the problem of inaccurate output data if the encoder accuracy is insufficient is solved.

[0015] The core of this rotary detection device lies in the fact that by adding a speed reducer 5, the problem of accurate output data at different output speeds and different operating angles is solved.
