Description

TECHNICAL FIELD

[0002] With the rapid development of rail transit, the operation efficiency and safety of high-speed trains and urban rail transit vehicles are increasingly improved. In these vehicles, the pantograph as a key component of the electric traction system directly affects the power supply stability and operation safety of the vehicle.

[0003] The pantograph transmits electric energy to the vehicle by contacting with the catenary to provide power for the vehicle. When the contact pressure is too small, the pantograph is prone to be separated from the catenary along the line and produce arc; when the contact pressure is too large, the catenary along the line is prone to have excessive lifting in the contact area with the pantograph, causing local bending and fatigue damage of the catenary, and increasing the wear of the carbon slide plates of the catenary and the pantograph, and even causing pantograph and catenary accidents.

[0004] Therefore, when the vehicle is in the depot for maintenance, the contact pressure between the pantograph and the catenary needs to be detected. When multiple pantographs are detected at the same time, partition devices before and after the pantographs are needed to partition, so as to eliminate the mutual interference of adjacent pantographs during detection. However, the position of the existing partition device after installation is not adjustable, and cannot adapt to the deformation of the catenary caused by temperature difference and vibration, so that the compatibility of the partition device to the installation position is poor.

The rotary support 13 is also called the joint of the machine, and is an important transmission element required by a machine in which relative rotary motion is required between two objects and axial force, radial force and overturning moment are required to be simultaneously borne.

[0053] The double-bow partition device for detecting the pressure of the vehicle pantograph provided by the embodiment of the application can adjust the position of the catenary clamping assembly 14 in the vertical plane through the lifting mounting base 12, adjust the position of the catenary clamping assembly 14 in the horizontal plane through the first hinge 11, and adjust the azimuth of the catenary clamping assembly 14 in the horizontal plane through the rotary support 13, so that the whole partition device can adapt to the deformation of the catenary caused by temperature difference change and vibration, and the compatibility of the installation position is improved.

Two nuts 124 are threaded on the screw rod 123 and fixedly connected with the movable plate 122. In use, the nut 124 is driven to lift along the screw rod 123 by rotating the screw rod 123, and the movable plate 122 is lifted by the nut 124.

[0068] One, two or more wire clamps 142 can be fixed on the slide rail 141. In use, the wire clamps 142 are used to clamp the catenary to achieve the connection between the isolation device and the catenary. When the catenary deforms due to temperature change or vibration, the slide rail 141 can slide relative to the slide base 143, and the slide base 143 can rotate about the vertical center line of the rotary support 13, thereby adapting to the deformation of the catenary and improving the reliability of the isolation device.
