Embodiment Construction

[0008] The present invention is owing to being contained in a kind of fast decoupling safety device between driving hook and quenching workpiece, and its implementation is as follows:

[0009] 1. The "8 combined body with crane and crane" of this device is put on the crane hook and tightened with left and right screws;

[0010] 2. Make two safety iron hooks according to the width of the heat treatment quenching oil pool of the enterprise, and each length is greater than 1 / 2 of the width of the quenching oil pool;

[0011] 3. Once there is a situation, the two workers on duty take the safety iron hook respectively, and at the same time hook the device "instant manual hook force";

Abstract

Disclosed is an unhooking safe device of heat treatment quenching, which is installed between a hook of a trolley and a quenching work-piece. The invention doesn't employ electric power, but employs a safe device of a mechanical locking structure which is formed by a safe quenching hook body, a safe quenching hook main body, a load bearing steel ball, a locking coat, a tension bolt, a connecting bar, a safe tommy bar, a crane trolley combined body, a real-time hook force position of labors and a quenching heavy object hook, wherein the tension bolt, the connecting bar and the safe tommy bar are arranged on the locking coat. When the heat treatment quenching trolley swings the work-piece to a quenching bath and once accidents happen with no electric power which can be used (particularly where near the quenching liquid is on fire), two operators hold iron hooks to respectively hook the real-time hook force location of the device, simultaneously pull the real-time hook force position emphatically, then, the locking coat of the device moves upwards under the leverage, the load bearing steel ball moves outwards under the action of the lateral component force of the gravity of the work-piece, and the safe quenching hook body and the quenching work-piece of the device immediately fast unhook to enter the quenching liquid to avoid fire risk.

Description

Technical field [0001] The present invention is a quick decoupling safety device between the suspension hook and the workpiece when the crane hangs the workpiece for heat treatment in the current small and medium-sized heat treatment plants (workshops). Background technique [0002] At present, small and medium-sized heat treatment plants (workshops) often use cranes to hoist heavy work objects to the quenching pool when they are heat-treated and quenched. The fire caused unnecessary heavy losses to the enterprise. Contents of the invention [0003] The present invention does not use electricity, but adopts a heat treatment quenching fast decoupling safety device with a mechanical locking structure, which is installed between the hook of the crane and the quenched workpiece; When the power is available (especially when the quenching liquid is on fire), as long as the two operators on duty hold the iron hooks, respectively hook the immediate manual hook force of the device...
