TECHNICAL FIELD
[0001] The utility model belongs to crane power supply technical field especially relates to a bridge crane power supply steel body slide contact line temperature compensation section connecting device. BACKGROUND
[0002] The power supply system of the bridge crane is realized through the contact sliding between the slide contact line and the current collector. This mechanism ensures that the electric energy can be continuously transmitted to the vehicle body of the crane, so that each mechanism of the crane can run smoothly, which is crucial for the production process. In this process, whether the slider of the current collector can run smoothly becomes a key factor to determine whether the power supply system can work normally. Usually, the power supply slide contact line of the crane is very long, and on each slide contact line, there are usually multiple cranes working at the same time. Therefore, once there is any problem with the current collector or the slide contact line, especially for high-voltage slide contact lines, the impact is extremely serious. In addition, the workload of maintaining and maintaining these devices is also quite huge. When the slider of the current collector wears out to one-third of its service life, if it deforms due to temperature changes and other factors when passing through the temperature compensation section or the maintenance section of the slide contact line, resulting in a rough surface, the current collector may collide, knock, or even produce an arc phenomenon during sliding. If the inspection work fails to discover these problems in time, in serious cases, the current collector may scratch the slide contact line, resulting in power failure of the entire power supply line, which is a great threat to production activities.
