Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a power connection device for a rail vehicle. Background Art

[0002] In the fields of industrial production, logistics and warehousing, railcars are widely used in material transportation, equipment inspection and other work scenarios because they can run accurately along the preset track. As a key component of the railcar, the power connection device is responsible for continuously and stably providing power to the trolley to ensure its normal operation. However, the current existing railcar power connection devices have exposed many problems in actual applications, which seriously affect the working efficiency, stability and safety of the railcar. The main problems include:

[0003] 1. Power supply stability issues

[0004] Many existing power connection devices use busbars and current collectors to supply power. During the long-term operation of the trolley, due to factors such as uneven tracks and trolley vibrations, the current collector and busbar are prone to momentary separation or unstable contact pressure. This will cause current transmission interruption or instability, causing the trolley to freeze in operation and damage electrical components.

[0005] In addition, as the use time increases, the contact area between the busbar and the collector will gradually wear due to friction. After the surface of the busbar is worn, its conductivity decreases and its resistance increases, which will not only increase the power loss, but also may cause local overheating, further accelerate the aging of the line, and even cause safety hazards such as fire. When the collector contacts are worn to a certain extent, they need to be replaced frequently, which increases maintenance costs and downtime, affecting production efficiency.

[0006] 2. Installation and maintenance complexity

[0007] (1) Difficulty in installation: The structural design of some power connection devices is relatively complex, and during the installation process, it is necessary to accurately adjust the flatness and verticality of the busbar and the relative position of the collector and the busbar. This not only requires high professional skills of the installers, but also takes a long time to install, increasing the time and cost of project construction. For example, some large automated warehouses have complex track layouts, and the installation of power connection devices is more difficult, requiring a lot of manpower and material resources to ensure installation accuracy.

[0008] (2) Inconvenient maintenance: When maintaining existing power connection devices, it is often necessary to shut down the machine and remove some equipment before internal inspection and repair. For some companies with continuous production, frequent shutdowns for maintenance of power connection devices will seriously affect production progress. Moreover, since power connection devices are usually installed at higher positions or in more hidden places, maintenance personnel have limited operating space, which increases the difficulty and danger of maintenance work.

[0009] 3. Many security issues

[0010] Some power connection devices fail to fully consider the safety protection of operators in their design. For example, the busbar may be exposed to the outside without effective insulation protection measures. When operators are performing other operations nearby, if they accidentally touch the live busbar, there is a risk of electric shock, threatening personal safety.

[0011] In summary, the existing power connection devices for rail cars have many problems in terms of power supply stability, environmental adaptability, installation and maintenance, and safety performance, and they are in urgent need of improvement and innovation to meet the needs of modern industrial production and logistics transportation for efficient, stable and safe operation of rail cars.

DETAILED DESCRIPTION

[0021] The power-leading device 1 can be provided with a power-leading insulating base 5, a copper electrode 6, a roller 7, a roller mounting seat 8, a mounting plate fixing screw 9, an electrode lead wire 10, and an insulating base fixing screw 11; the power-receiving device 2 includes a fixed base plate 12, a power-receiving insulating base assembly 13, a carbon brush electrode assembly 14, a freedom-constrained axial screw 15, and a fixed base plate connecting screw 16; wherein the electrode lead wire 10 is connected to the copper electrode 6 by soldering; the roller 7 and the roller mounting seat 8 are connected by threaded fastening; the combination of the electrode lead wire 10 and the copper electrode 6, and the combination of the roller 7 and the roller mounting seat 8 that complete the above connection are respectively fixed to the corresponding positions of the electric insulating base 5 by bonding with thermal conductive insulating glue and the mounting plate fixing screw 9; the carbon brush electrode assembly 14 is hinged in the power-receiving insulating base assembly 13 by using a freedom-constrained axial screw, and then the combination is installed on the fixed base plate 12 by threaded cooperation introduced by the freedom-constrained axial screw 15 and the fixed base plate connecting screw 16 and the axial hole cooperation.

[0022] The power receiving insulating base assembly 13 may include a power receiving insulating base 17 and a stainless steel outer compression spring 18 ; wherein the power receiving insulating base 17 and the stainless steel outer compression spring 18 are connected in the form of an axial hole interference fit.

[0023] The carbon brush electrode assembly 14 can be configured to include a carbon brush 19, a carbon brush mounting seat 20, a carbon brush mounting seat freedom constraint angle plate 21, an angle plate fixing screw 22, and a stainless steel internal compression spring 23; wherein the carbon brush mounting seat freedom constraint angle plate 21 is fixed to the bottom surface of the carbon brush mounting seat 20 by the angle plate fixing screw 22; the stainless steel internal compression spring 23 is installed with the carbon brush mounting seat 20 by interference fit in the axial hole; the carbon brush 19 is fixed to the inside of the carbon brush mounting seat 20 by bonding with thermally conductive insulating adhesive.

[0024] The working principle of the present invention is: When the trolley 4 enters the working position, the power receiving device 2 will move with the trolley 4.
