Technical Field
[0001] The utility model relates to the technical field of reducers, in particular to a reducer for an anti-jamming bucket elevator. Background Art
[0002] Hoist is a large mechanical equipment that transports by changing potential energy. Most existing hoists use reducers as power transmission sources.
[0003] If the reducer overheats during operation, its output shaft may get stuck. In addition, if the output shaft of the reducer lacks lubrication, it may get stuck. The heat dissipation performance of existing reducers is average. If the outside weather temperature is high, the reducer is likely to overheat during operation. In addition, the existing reducer does not have the function of automatic lubrication, which may cause its output shaft to get stuck due to lack of lubrication. Therefore, in view of the above situation, it is urgent to develop a reducer for bucket elevators that has good heat dissipation and automatic lubrication to prevent the output shaft of the reducer from getting stuck during operation, so as to overcome the shortcomings in current practical applications and meet current needs.

The base is fixed with a bracket, and the inner side of the bracket is fixed with a reducer on the base. The upper side and the right side of the bracket are both equipped with a plurality of auxiliary heat dissipation devices that fit the reducer. The bracket is equipped with an automatic lubrication mechanism pointing to the output shaft of the reducer. The inner left side of the bracket is equipped with a temperature sensor attached to the reducer. The left side of the bracket is equipped with a control cleaning. The automatic lubrication mechanism comprises: a lubricating oil storage cylinder, a plug, a drip nozzle, a micro motor and an eccentric cam. The lubricating oil storage cylinder is installed on the top of the bracket, and the lubricating oil storage cylinder is detachably equipped with a plug.

The micro motor is fixed in the bracket, and the output shaft of the micro motor is connected to the eccentric cam, and the eccentric cam fits with the bottom of the drip nozzle.
[0007] As a further solution of the utility model: the auxiliary heat dissipation device includes: a T-shaped heat conductive sheet, a semiconductor refrigeration sheet and heat dissipation fins, the T-shaped heat conductive sheet is fixed on the bracket, one end of the T-shaped heat conductive sheet is in contact with the reducer, a semiconductor refrigeration sheet is installed on the T-shaped heat conductive sheet, and heat dissipation fins are installed on the semiconductor refrigeration sheet.

[0009] As a further solution of the utility model: the semiconductor refrigeration sheet, micro motor and temperature sensor are all electrically connected to the control unit.
[0010] Beneficial effects: When the reducer for the anti-jamming bucket elevator is in use, the heat on the reducer is dissipated outwards through the T-shaped heat conductive sheet, and the temperature of the reducer is detected by the temperature sensor. When the temperature of the reducer is too high, the control unit controls the semiconductor refrigeration sheet to start, and the T-shaped heat conductive sheet is cooled and cooled by the semiconductor refrigeration sheet, thereby improving the heat dissipation effect of the reducer. In addition, the control unit controls the micro motor to rotate one circle every two days, and the eccentric cam is driven by the micro motor to rotate one circle.

The base 1 is fixed with a bracket 2, and the inner side of the bracket 2 is fixed with a reducer 3 on the base 1. The upper side and right side of the bracket 2 are both equipped with a plurality of auxiliary heat dissipation devices 4 that fit the reducer 3. The bracket 2 is equipped with an automatic lubrication mechanism 5 pointing to the output shaft of the reducer 3, and the inner left side of the bracket 2 is equipped with a The temperature sensor 6 on the reducer 3 is connected to the control unit 7 on the left side of the bracket 2.

The T-shaped heat conductive sheet 401 is fixed to the bracket 2. One end of the T-shaped heat conductive sheet 401 is in contact with the reducer 3. The semiconductor cooling sheet 402 is installed on the T-shaped heat conductive sheet 401. The heat dissipation fin 403 is installed on the semiconductor cooling sheet 402. The heat at the hot end of the semiconductor cooling sheet 402 is transferred to the heat dissipation fin 403. The heat on the reducer 3 is dissipated outward through the T-shaped heat conductive sheet 401, so as to ensure the continuous cooling effect of the semiconductor refrigeration sheet 402. The T-shaped heat conductive sheet 401 and the heat dissipating fins 403 are made of copper, so that they have good thermal conductivity. When in use, the heat on the reducer 3 is dissipated outward through the T-shaped heat conductive sheet 401. The automatic lubrication mechanism 5 includes: a lubricating oil storage cylinder 501, a plug 502, a drip nozzle 503, a micro motor 504 and an eccentric cam 505. The lubricating oil storage cylinder 501 is installed on the top of the bracket 2. The plug can be detachably installed on the lubricating oil storage cylinder 501.
