Manual handle operating structure of winch rope safety device

Abstract

The invention relates to a manual handle operating structure of a winch rope safety device. The winch is hand operated to move up and down through a hand operated handle. In the manual handle operating structure of the winch rope safety device, a rope (20) is introduced into a housing (30) through a leading-in hole (31), and is wound on a pulley (40) for a circle, and then is discharged from a discharging hole, the winch driven by a motor (50) is moved up and down through the rope (20), one side of the housing (30) of the winch (10) is provided with a safety device (60) used for adjusting the tensile force of the rope and preventing the rope from being wound, one side of the upper part of the winch is provided with an emergency rod (70) used for relieving a brake during the emergency moment, the lower part of the winch forms a lower handle connecting shaft (80) connected with a driving shaft (11), the hand operated handle (90) in the lower space of the winch (10) can be connected to the lower handle connecting shaft (80) for operation.

Description

technical field [0001] The present invention relates to a manual handle operation structure of a winch rope safety device, more particularly, relates to a manual handle for lifting and lowering a winch in a manual operation mode, and can easily operate (rotate) the manual handle for lifting in the lower space of the winch The manual handle operation structure of the winch rope safety device. Background technique [0002] Ordinary endless winder (Endless Winder) is used as a device for lifting or lowering weight objects and personnel, and many kinds of winders have been applied for and used in the prior art. [0003] That is, a hoist is a device that rotates a cylindrical drum to move a heavy object by a rope or chain wound on the drum, or lifts an object by using a pulley, and its small size is called a manual hoist. The drum is driven by rotating the handle by hand through gears, and a brake is installed so that the heavy object does not fall even if the hand is released f...

Problems solved by technology

[0009] But, for the manual handle operation structure of the existing winch rope safety device, because the handle connection shaft 8 that is connected with the manual handle 9 is formed on the top of the winch 1, when the winch 1 is provided with a cover, the structure of the winch 1 cannot be adjusted. The problem that the manual handle 9 cannot be operated due to the narrow upper space

[0010] In addition, when the hoisting machine 1 is installed in a narrow space in the past, when the handle is operated, it interferes with surrounding objects and cannot be smoothly and quickly rotated. In addition, in order to operate (rotate) the manual handle 9 smoothly, it is necessary to Objects located in the periphery, that is, objects that interfere when the handle is rotated, are moved to other places, which is not only troublesome, but also the space for the radius of rotation cannot be secured when the handle is operated due to the interfering object, resulting in complete inability to operate the handle, etc. more disadvantages
