Problems solved by technology

[0002] Due to the high temperature in the heating furnace, the working environment is harsh
The conventional method used by operators when loading and unloading materials is to hang the hook on the loading tool with a long pole in hand, but this method of operation is prone to danger or burns due to being too close to the heating furnace
Moreover, since the traditional operation method requires the operator to be close to the hoisted high-temperature workpiece, serious accidents will occur if the workpiece falls
In addition, the hoisting efficiency of the traditional method is low, which affects the work efficiency of the entire production line

Abstract

The invention provides a self-locking device of lifting hooks. A collision block and a self-locking part are arranged on the self-locking device, the collision block is fixedly connected with a first connecting shaft and a third connecting shaft, and a second connecting shaft slides on the collision block; when the collision block moves to the lowest position downwards, the lifting hooks are opened, and when the collision block moves to the highest position upwards, the lifting hooks are closed; when the collision block moves to the lowest position or the highest position, the self-locking portion forms self locking, and the opening or closing state of the lifting hooks is kept; and the device has the beneficial effects of being simple in structure, ingenious in design, convenient to operate, safe to use, capable of achieving automatic loading and unloading and improving efficiency and the like.

Description

technical field [0001] The invention belongs to the field of heating furnaces, in particular to a hook self-locking device used for hoisting in and out of a heat treatment production line. Background technique [0002] Due to the high temperature in the heating furnace, the working environment is harsh. And the conventional method that the operator adopts when loading and unloading is to hang the hook on the charging tool with a long pole in hand, but this method of operation is likely to cause danger or burns due to being too close to the heating furnace. Moreover, since the traditional operation method requires the operator to be close to the hoisted high-temperature workpiece, serious accidents will occur in case the workpiece falls. In addition, the hoisting efficiency of the traditional method is low, which affects the work efficiency of the entire production line. Contents of the invention [0003] The object of the present invention is to provide a hook self-locki...
