[0002] The automatic tension compensation device of the contact network is an important part of the contact network. The compensation efficiency and effect are directly related to the size of the contact network tension and the wave propagation speed, thus affecting the performance and operational safety of the contact network. In addition to meeting the requirements of contact network tension compensation, the ratchet compensation device must also have good wire break stopping performance, which can effectively reduce the affected range of the equipment and reduce the accident level in the event of a fault (accident). In the design of new construction and modification of the contact network, the ratchet compensation device is also commonly used for the compensation device of the center anchor section installed in the form of anti-channeling but not anti-breakage, which makes up for the deficiency of the anti-channeling center anchor in the event of a wire break fault.

[0003] The main problems with the ratchet compensation device are the eccentric wear of the compensation rope of the ratchet compensation device and the ratchet body and the wire groove, and the jamming and loosening of the limit frame.
