[0020] Embodiment 1

[0021] As Figure 1 and Figure 3 shown, this application provides a detection device for axial displacement alarm of a bucket wheel hydraulic motor, including a bucket wheel 1, a torsion arm 2 and a motor 3 arranged on one side of the bucket wheel 1. An induction bracket 4 that moves with the displacement of the motor 3 is arranged outside the motor 3. A guardrail 5 is arranged on one side of the motor 3, and an early warning monitoring mechanism 6 for monitoring the displacement of the motor 3 and giving an early warning is arranged on one side of the guardrail 5. The early warning monitoring mechanism 6 includes a connection component 61 arranged on one side of the guardrail 5 for monitoring the displacement of the motor 3, and an alarm component 62 for giving an early warning is arranged above the guardrail 5.

[0022] A plurality of storage hoppers 11 for storing materials are arranged outside the bucket wheel 1. One side of the bucket wheel 1 is fixedly connected to the torsion arm 2, and the motor 3 is fixed to one end of the torsion arm 2 by bolts.

[0023] In this embodiment, when the bolts of the motor 3 become loose or fatigue breaks, the motor 3 has an axial left displacement. The induction bracket 4 moves with the motor 3. When the induction bracket 4 moves, the connection component 61 monitors that the induction bracket 4 moves away. The connection component 61 gives an audible and visual early warning through the alarm component 62, prompting the driver to stop the operation for inspection and confirmation, realizing the early discovery of the displacement phenomenon of the motor 3, avoiding the continuous displacement and dropping of the motor 3, and improving the intrinsic safety of the equipment.

[0024] As Figure 2 and Figure 4 and Figure 5As shown in the figure, the induction bracket 4 is fixedly connected to the outside of the motor 3. On one side of the induction bracket 4, a detection limit bracket 41 is fixedly connected. Below the detection limit bracket 41, a vertical rod 42 is fixedly connected. On one side below the vertical rod 42, a horizontal rod 43 is fixedly connected. The horizontal rod 43 is fixedly connected to one side of the guardrail 5.

[0025] On one side above the guardrail 5, a fixing plate 51 corresponding to the connection component 61 is fixedly connected.

[0026] The connection component 61 includes an L-shaped rod 611 fixedly connected to one side of the guardrail 5. At the upper end of the L-shaped rod 611, a fixing rod 612 is fixedly connected. At one end of the fixing rod 612 close to the detection limit bracket 41, a connecting plate 613 is fixedly connected. A detection probe 614 is fixedly connected through the connecting plate 613. The distance between the detection probe 614 and 41 is 5 mm. One end of the detection probe 614 is fixedly connected to a connecting wire 615. A fixing ring 616 is arranged on the outside of the fixing rod 612 for the connecting wire 615. The fixing ring 616 fixes the connecting wire 615 on one side of the fixing rod 612. One end of the connecting wire 615 is provided with a control box 617. A processing module is arranged in 617. The control box 617 is fixedly connected above the fixing plate 51.

On one side of the connecting vertical rod 621, a connecting shell 622 for emitting a sound prompt is fixedly connected. A sound warning module is arranged in the connecting shell 622. Above the connecting shell 622, a lighting element 623 for flashing prompt is fixedly connected. The connecting shell 622 is directly connected to the control box 617 through a data transmission line.

[0028] In this embodiment, when the induction bracket 4 moves, it drives the detection limit bracket 41 to move. The distance between the detection limit bracket 41 and the detection probe 614 becomes larger. The connecting wire 615 transmits the monitoring information of the detection probe 614 to the processing module in the control box 617. The processing module in the control box 617 processes the information and sends a control signal through the data transmission line to make the sound warning module in the connecting shell 622 emit a sound, and the lighting element 623 starts to flash, prompting the driver to stop the operation, realizing the early discovery of the displacement phenomenon of the motor 3, avoiding the continuous displacement and falling of the motor 3, and improving the intrinsic safety of the equipment.
