TECHNICAL FIELD
[0001] The utility model belongs to the RGV technical field, specifically belongs to a heavy rail RGV carrier. BACKGROUND
[0002] The carrier is mainly used for transporting paper rolls between cross cars, or transporting single or multiple paper roll cores from a rewinding machine workshop to a paper machine workshop. Generally, such carriers mainly use cable drums for power supply or wireless power supply. The cable drum system needs regular maintenance. After long-term use, the insulation performance of the cable may decrease, increasing the risk of electrical failure. The cable needs to be replaced regularly when it is aged or damaged. In harsh environmental conditions, such as high temperature, low temperature, humidity or corrosive environment, the performance and service life of the cable drum will be affected, which may cause frequent failures. Wireless power supply is expensive, and the farther the carrying distance, the higher the cost. If there is water on the ground, it may cause electrical failure. If the paper rolls are transported across the workshop, there will be expansion joints at the connection between the two workshops, and the ground will settle on both sides of the expansion joint, causing the gap between the brush and the power supply plate to be too large, which may cause power failure and electrical failure. Some carriers use batteries for power supply and charge the batteries through charging stations. In order to facilitate automatic charging of the batteries in the carrier and the charging station, a quick connector (such as a brush plate brush block) is often used to connect the carrier and the charging station. However, since the position of the brush plate brush block is fixed after the mobile trolley and the charging station are produced, if the installation ground is uneven, the brush plate brush block may not be able to ensure normal charging after the charging station and the mobile trolley are installed.
