Haulage winch

Abstract

The invention discloses a haulage winch which comprises a base, a motor, a decelerating transmission system, a winding drum, a braking device, an operating device, a depth indicator and a console, wherein the motor is mounted on the right side of the base, the output shaft of the motor is connected with the winding drum through the decelerating transmission system, the decelerating transmission system is arranged inside the winding drum, the braking device comprises a first brake wheel, a second brake wheel, a first work brake, a second work brake, and a safety brake, the console is fixed on the base in front of the winding drum, the operating device comprises a first operating handle and a second operating handle, the first operating handle is used for controlling the brake of the first brake, the second operating handle is used for controlling the brake of the second brake, the depth indicator is mounted above the rear side of the winding drum, the two operating handles are respectively mounted on the base in front of the control console and positioned on the left and the right sides of the console, the radial distance between each operating handle and the winding drum is set to be L, the radial distance between each operating handle and each brake drum is M, and the L is larger than the M.

Description

technical field [0001] The invention relates to a transportation device, in particular to a transportation winch. Background technique [0002] The working principle of the transport winch is to provide torque to the reel 12 through the motor 11 through the reducer system, use the wire rope to wind the reel, and the brake device to control the operation and stop of the reel to meet the purpose of dispatching and transporting materials. In order to make the structure of the winch compact, the deceleration system is usually placed in the reel body, and the motor shaft extends into the reel body; in order to ensure the safety and reliability of the winch, the winch is designed with three sets of braking devices, two of which are working brakes 13, and one is a brake. Safety brake 14, wherein a secondary working brake plays a clutching effect. The safety brake is controlled by a hydraulic hydraulic brake, and the working brake is manually operated by a person. Such as figure ...

AI Technical Summary

Problems solved by technology

like figure 1 The shown safety brake 14 is installed on one side close to the motor 11, and the two working brakes 13 are placed on the other side of the motor 11. The position of the operating handle 15 is as follows: figure 1 As shown, it is very close to the working brake 13, because the diameter of the brake wheel 17 and the diameter of the drum baffle 16 are relatively large, the radial distance to the handle 15 is small, and because the distance between the two brake wheels Closer, so that the axial operating distance of the two operating handles 15 is also smaller, the operating space for workers is too small, and the field of vision is limited
