Abstract

A multipurpose two-speed winch relates to the field of winch variable speed mechanical devices. In order to solve the problem that the existing winches do not have the function of speed adjustment, manual braking is adopted, which has a large risk factor and easily leads to dangerous events. The output end of the motor is connected to the brake wheel device through a coupling, the shaft hole of the brake wheel device is connected to one end of the input shaft through a keyway, and the other end of the input shaft is connected to the side plate bore of the gearbox. The output end of the drum is connected to one end of the main shaft. There are two bearing cups on the web plate of the drum. The main shaft is connected to the bore hole of the web plate of the drum through bearings. Each bearing cup is provided with a bearing, and the inner ring of the bearing is set on the main shaft. The other end of the main shaft passes through the transmission mechanism and is set in the bore of the bearing bracket, and the transmission mechanism is set in the inner cavity of the drum. The brass oil nozzle is installed in the gland hole of the bearing bracket, and the left end extends into the bore of the winch bearing bracket. cavity. The invention is suitable for winches used in mining operations.

Description

technical field [0001] The invention relates to the field of winch variable speed mechanical devices, in particular to a multi-purpose two-speed winch. Background technique [0002] At present, when mining in mines, miners use winches to work in mines. The existing winches use manual shifting transmission as an independent component. After connecting with the reducer through a coupling, the drum device is driven through the coupling. The function of speed modulation, and the braking system of the drum is manual braking. When danger occurs, emergency braking is required. Manual braking cannot be used to brake in time, resulting in danger and serious life-threatening. [0003] To sum up, the existing winches do not have the function of speed adjustment, and manual braking is used, which has a large risk factor and easily leads to the occurrence of dangerous events. Contents of the invention [0004] The present invention proposes a multi-purpose two-speed winch to solve the...
