Preferably, the conductive hook comprises a load sliding frame connected with the transmission chain and a hook main body connected to the lower portion of the load sliding frame, the hook main body is movably connected with the load sliding frame and always vertically and naturally connected with the ground, and an opening of the hook oil receiving piece is upwards connected to the hook main body. The conveying process has at least a descending section when immersed in the immersion tank, and an ascending section when immersed out of the immersion tank, and the lubricating oil in the oil receiving piece can flow along with the change of the direction of the oil receiving piece.

Preferably, the hook main body comprises a connecting piece connected with the load carriage, an insulating material, a primary hook which is insulated by the insulating material and connected below the connecting piece, and a conductive piece arranged on the primary hook, and the hook oil receiving piece is connected with the connecting piece and is higher than the insulating material. In the structure, the hook oil receiving piece is connected to the connecting piece, only the primary hook and the workpiece to be processed hung on the primary hook are electrified through the conductive piece when the workpiece is conveyed to the power-on working section, and the parts above the insulating material are not electrified.

Preferably, the chain oil receiving piece is connected to the transmission chain by two chain oil receiving connecting pieces with the same length. Most lubricating oil can drip from the head part of the hook, and the amount of the lubricating oil dripping into the chain oil receiving piece is small, so that the lubricating oil can not flow out of the chain oil receiving piece caused by ascending or descending, and the direction is not required to be limited particularly. In order to facilitate connection and reduce vibration of a suspension conveying chain, two chain oil receiving connecting pieces with the same length are connected to the transmission chain, the structure enables the direction of the chain oil receiving piece to be always parallel to the transmission chain, and the oil receiving range is easy to ensure when design is carried out.

In the conveying process, the chain may vibrate slightly, the workpiece is hung due to the fact that the hanging hook is long, shaking may occur, if the installation height of the hanging hook oil receiving part is consistent with that of the chain oil receiving part, namely, the distance from the chain is consistent, the oil receiving effect is affected due to the fact that collision between the two oil receiving parts is easy, and the hanging hook oil receiving part and the chain oil receiving part are arranged in a staggered mode in height, so that the situation can be avoided. The head of the hook needs to occupy a certain longitudinal space, so that the limit height of the oil receiving part of the hook is lower than that of the oil receiving part of the chain, and the installation height of the oil receiving part of the chain, which is higher than that of the oil receiving part of the hook, can be the smallest, so that the overall required installation height of the hanging conveying device is suitable for more application scenes.

Preferably, each chain oil receiving piece and a conductive hook are alternately arranged below the transmission chain. The load carriage on the conductive hooks has the function of supporting the transmission chain, and cannot be excessively spaced to avoid bending and sagging of the transmission chain.
