Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical equipment technical field especially relates to a rail trolley power connection device. BACKGROUND

[0002] In the field of industrial production, logistics and warehousing, rail trolley can run accurately along the preset track, and is widely used in material transportation, equipment inspection and other work scenes. As a key component of the rail trolley, the power connection device is responsible for providing stable power supply for the trolley to ensure its normal operation. However, the current existing rail trolley power connection device has exposed many problems in practical application, which seriously affects the working efficiency, stability and safety of the rail trolley. The main problems include:

[0003] 1. Power supply stability problem

[0004] Many existing power connection devices use the method of sliding contact line and collector to supply power. In the long-term operation of the rail trolley, due to factors such as track unevenness and trolley vibration, the collector and the sliding contact line are prone to instantaneous disconnection or unstable contact pressure. This will cause the interruption or instability of current transmission, causing the trolley to run jammed, electrical components damaged and other problems.

[0005] In addition, with the increase of use time, the contact parts of the sliding contact line and the collector will gradually wear out due to friction. After the surface of the sliding contact line is worn out, its conductivity decreases and the resistance increases, which not only causes the increase of power loss, but also may cause local overheating, further accelerating the aging of the line, and even causing fire and other safety hazards. When the contact of the collector is worn to a certain extent, it needs to be replaced frequently, which increases the maintenance cost and downtime, affecting the production efficiency.

[0006] 2. Installation and maintenance complexity problem

[0007] (1) Difficulty in installation: The structure design of some power connection devices is relatively complex, and the flatness, perpendicularity of the sliding contact line and the relative position of the collector and the sliding contact line need to be accurately adjusted during installation. This not only requires high professional skills of the installation personnel, but also takes a long time in the installation process, increasing the time and cost of project construction. For example, some large automatic stereoscopic warehouses have complex track layout, and the installation of the power connection device is more difficult, which requires a lot of manpower and material resources to ensure the installation accuracy.

[0008] (2) Maintenance is not convenient: When maintaining the existing power connection device, it is often necessary to stop the machine and remove part of the equipment to check and repair the inside. For some continuous production enterprises, frequent shutdown for maintenance of the power connection device will seriously affect the production progress. Moreover, since the power connection device is usually installed in a high position or a hidden place, the operation space of the maintenance personnel is limited, which increases the difficulty and danger of the maintenance work.

[0009] 3. More safety problems

[0010] Some power connection devices do not fully consider the safety protection of the operating personnel in the design. For example, the slide wire may be exposed without effective insulation protection measures, and when the operating personnel is near to perform other operations, accidentally touching the live slide wire, there is a risk of electric shock, threatening personal safety.

[0011] In summary, the existing power connection device for rail trolley has many problems in power supply stability, environmental adaptability, installation and maintenance, and safety performance, and needs to be improved and innovated to meet the needs of modern industrial production and logistics transportation for efficient, stable and safe operation of the rail trolley.
