Description

A protective device for installing the ground travel motor of a semi-gantry crane

Technical Field

The utility model relates to the technical field of gantry cranes, in particular to a ground travel motor installation protection device for a semi-gantry crane.

Background Art

During the electroplating production process, an electroplating gantry crane is usually required to transport materials to the electroplating tank for electroplating.

In the prior art, Chinese patent publication number CN211374450U discloses a drip-proof gantry crane, which includes a crane guide rail, a crane frame movably arranged on the crane guide rail, a lifting arm movably arranged on the crane frame and used to lift or lower a turnover material frame, and a liquid receiving device movably arranged on the crane frame, wherein the liquid receiving device includes a liquid receiving tray and a first driving device for driving the liquid receiving tray to move horizontally. When the drip-proof gantry crane of the utility model is used, when the workpiece is inspected and transferred, the crane frame controls the lifting or lowering of the turnover material frame by controlling the lifting and lowering of the lifting arm. When the crane frame lifts the turnover material frame to the top of the liquid receiving device, the first driving device drives the liquid receiving tray to move to the bottom of the turnover material frame, and the liquid receiving tray catches the liquid dripping from the turnover material frame to prevent the liquid from dripping on the inspection line or the ground, causing contamination or liquid cross-talk.
