Description

Technical Field

[0001] The utility model relates to the technical field of quenching furnace lifting tools, and particularly relates to a quenching furnace lifting tool. Background Technique

[0002] When carrying out metal heat treatment work, a quenching furnace is often required. The quenching furnace is a non-standard electric furnace specially designed according to user requirements, and is mainly used for heat treatment such as quenching and heating of various workpieces in the aluminum industry. In order to facilitate the placement of the workpiece into the interior of the quenching furnace for quenching, a lifting tool needs to be used to complete the quenching work.

[0003] A Chinese patent with the publication number CN219009720U discloses a quenching furnace lifting tool; it includes a lifting arm and an auxiliary device. The auxiliary device includes a first clamping arm, a second clamping arm, a first support arm, a second support arm, a clamping block and a power assembly. During the heat treatment of metal parts, the lifting arm can be lifted by an external lifting mechanism for transfer. When clamping parts, the power assembly acts. First, the first clamping arm and the second clamping arm move away from each other. Then, after the first clamping arm and the second clamping arm drive the clamping block to move to both sides of the part, the power assembly acts again, making the first clamping arm and the second clamping arm approach each other, so that the clamping block can abut against the part and clamp it, so as to be more convenient for clamping and lifting some medium and large-sized single metal parts with different lengths during metal heat treatment.

[0004] However, the above patent has the following deficiencies: The above patent clamps and moves the quenching furnace through two clamping blocks. However, when using it, there is a risk of dropping when only clamping the quenching furnace with two clamping blocks, so it needs to be improved. Content of the Utility Model
