Description

Technical Field

[0001] The utility model relates to the field of gantry crane busbars, in particular to a gantry crane busbar safety device. Background Art

[0002] A gantry crane is a variation of a bridge crane, also known as a gantry crane. It is mainly used for heavy-duty loading and unloading operations outdoors. Due to the movement, it needs to constantly change positions. At each different position, the mobile equipment must be able to obtain power at any time, otherwise it will not be able to continue moving. At this time, the busbar came into being. Several conductors are laid in parallel along the running track of the mobile equipment and connected to the power supply. On the moving equipment, a collector that can draw electricity from the conductor is installed. The gantry crane busbar is usually loaded with a high load during use, and a lot of heat is generated inside. When running outdoors, the ambient temperature is too high, which will cause the guide rail to expand and contract and deform, resulting in the collector being blocked or the collector being out of the slot and power off, which is very unsafe. In addition, the collector brush is in direct contact with the conductor, which generates greater friction and vibration, and the brush wears out quickly. And it is easy to damage the conductor.

[0003] The existing patent announcement number CN219567343U discloses a gantry crane safety busbar safety device with a sunshade added to the guide rail, but this device only solves the heating caused by the external environment, and does not solve the heating problem caused by the internal high load.

[0004] In view of the above problems, we propose a gantry crane busbar safety device. Utility Model Content

[0005] The purpose of the utility model is to solve the defects in the prior art that "this device only solves the heating caused by the external environment, but does not solve the heating problem caused by the internal high load, and the collector brush is in direct contact with the conductor, which produces large friction and vibration, and the brush wears quickly.
