Technical Field

[0001] The utility model belongs to the technical field of double-drive chain heavy-load power systems, and in particular relates to a double-drive chain slag scoop machine reducer or motor fault detection device. Background Art

[0002] In the production process of thermal power plants, dual-drive chain scraper slag removers account for a certain number. The boiler's driven chain scraper slag remover discharges the cooled slag into the slag bin of the slag storage facility. In order to ensure the reliability of the equipment, a dual-drive mode with the same power supply is adopted to ensure the output balance of the drive gears on both sides.

[0003] When the original device failed to produce power due to a single-side motor failure or a single-side reducer failure, the on-site operating personnel were unable to discover it in time, causing the single-side motor drive to cause equipment failure. Utility Model Content

[0007] In order to further realize the utility model, the top surface of the horizontal plate is flush with the right-angle side I of the triangular bracket.

[0008] In order to further realize the utility model, a rotating pin is arranged between the arm-type towing rod and the triangular bracket for connection.

[0009] In order to further realize the utility model, a rotating shaft connection is arranged between the arm-type towing rod and the chain guide wheel.

[0010] In order to further realize the utility model, the guide rod is parallel to the right-angle side II of the triangular bracket.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model determines the operating condition of a single-sided or double-sided reducer by detecting the tension and relaxation force of the drive chain, can solve the problem of equipment damage caused by failure of a single-sided motor or reducer that cannot be discovered in time, and improves the operating safety of the reducer of a dual-drive chain slag scoop machine.

[0013] The arm type support rod in the utility model is used to move up and down with the triangular bracket as a fulcrum; the chain guide wheel is used to detect the tension and relaxation force of the detection chain and transmit it to the arm type support rod; the guide rod position detection device is used to trigger a protective action alarm or stop operation by detecting the displacement of the arm type support rod and the triangular bracket.

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 As shown, a double-drive chain slag scoop reducer or motor fault detection device comprises a triangular bracket 1, a horizontal plate 2 and an arm-type drag rod 3. The triangular bracket 1 is a right-angled triangle. The horizontal plate 2 is arranged on the hypotenuse of the triangular bracket 1. The top surface of the horizontal plate 2 is flush with the right-angle side Ⅰ1-1 of the triangular bracket 1. One end of the arm-type drag rod 3 is rotatably connected to the side wall of the triangular bracket 1. A rotating pin is arranged between the arm-type drag rod 3 and the triangular bracket 1. A chain guide wheel 4 is arranged at the other end of the arm-type drag rod 3. A rotating shaft is arranged between the arm-type drag rod 3 and the chain guide wheel 4. A guide rod 5 is vertically arranged on the horizontal plate 2. The guide rod 5 is parallel to the right-angle side Ⅱ1-2 of the triangular bracket 1. The bottom end of the guide rod 5 is rotatably connected to the arm-type drag rod 3. A plurality of positioning blocks 6 are symmetrically arranged on the horizontal plate 2. The guide rod 6 is clamped between the positioning blocks 6. A guide rod position detection mechanism 7 is arranged on the triangular bracket 1 or the horizontal plate 2.

[0020] like Figure 2As shown, the driving motor 8 drives the main driving wheel 10 of the slag picker to operate continuously through the driving chain 9. Due to the use of a dual-drive motor, the utility model symmetrically arranged on both sides is used to detect whether the single-side drive is normal, that is, the right-angle side II1-2 of the triangular bracket is fixedly connected to the side wall of the driving slag picker 11. When a single-side driving motor or reducer fails, the return chain side of the driving chain 9 will change from the original relaxed state to the tight state, driving the chain guide wheel 4 to move upward, and the chain guide wheel 4 drives the arm-type support rod 3 to move upward. The arm-type support rod 3 pushes the guide rod 5 to move upward under the restriction of the positioning block 6. The guide rod position detection device 7 sends an alarm or tripping signal by detecting the displacement of the guide rod 5 to remind the on-duty personnel or protect the shutdown, thereby achieving the function of protecting the equipment.
