Symmetric conveying and transporting winch for mine

Abstract

The invention discloses a symmetric conveying and transporting winch for mine. The symmetric conveying and transporting winch for mine comprises a base, wherein the base is provided with an electric motor and a winding drum device; the electric motor is connected with a speed reducer through a shaft coupler; an electric hydraulic brake is arranged outside the shaft coupler; the winding drum device comprises a winding drum, a winding drum shaft and a big gear ring; the speed reducer comprises a bevel gear box and a carrier gear box; a lengthways input shaft is arranged at one side of the bevel gear box; shaft gears are arranged at the end parts of the input shaft; big gears are respectively engaged at two sides of each shaft gear; the big gears at two sides are respectively mounted at the front end of the transversely flat key shaft; a sun gear is arranged at the rear end of the flat key shaft; multiple planetary gears are engaged outside the sun gear; and the planetary gears are respectively rotationally mounted on a turntable of a planetary frame. The symmetric conveying and transporting winch for mine, disclosed by the invention, has the advantages of a completely symmetric structure, high transmission efficiency, satisfaction with reliability of large-tonnage soft start systems and brake systems, simple production technology, operation convenience, and better safety as well as reliability; and rope rewinding and releasing operations and braking operation can be realized without starting up the electric motor by turning positively and negatively frequently when the symmetric conveying and transporting winch for mine is in use.

Description

technical field [0001] The invention relates to a new type of mining transport machinery, in particular to a new mining transport winch with planetary soft start. Background technique [0002] Patent No. 03132226.3 has been authorized by the Patent Office of the State Intellectual Property Office. This patent discloses a technical solution for handling and transporting winches. It is suitable for the narrow working space in the underground of coal mines, but it needs to start the motor frequently in forward and reverse directions during use, and there are problems such as high noise in use. For example, the brake belt is used to brake the outer ring of the inner gear to realize the transmission. One end of the brake belt is fixed to the base, and the other end is connected to the hand brake connecting rod. It is further amplified and acts on the outer ring of the inner gear, and a large radial force acts on the outer ring of the inner gear, resulting in severe vibration, lo...

[0002] Patent No. 03132226.3 has been authorized by the Patent Office of the State Intellectual Property Office. This patent discloses a technical solution for handling and transporting winches. It is suitable for the narrow working space in the underground of coal mines, etc., but it needs to start the motor frequently in forward and reverse directions during use, and there are problems such as loud noise in use

For example, the brake belt is used to brake the outer ring of the inner gear to realize the transmission. One end of the brake belt is fixed to the base, and the other end is connected to the hand brake connecting rod. Further amplify and act on the outer ring of the inner gear, and a large radial force acts on the outer ring of the inner gear, resulting in severe vibration, loud noise, and serious friction and heat generation during the transmission process, bringing certain safety hazards
