The invention discloses an anti-slip wheel stopping device of a shield electric locomotive, and relates to the technical field of shield electric locomotives. The device comprises an electromagnetic valve, a frequency converter and an anti-slip mechanism which are assembled on the shield electric locomotive, the electromagnetic valve and the frequency converter are both assembled in the cab of the shield electric locomotive, the anti-slip mechanism is assembled at the rear end of a wheel of the shield electric locomotive, and an anti-slip iron wedge is assembled at the lower end of the anti-slip mechanism. When the shield electric locomotive stops, the anti-slip mechanism automatically drives the anti-slip iron wedge to fall to limit the wheels of the shield electric locomotive, and when the shield electric locomotive runs, the anti-slip mechanism automatically drives the anti-slip iron wedge to rise. According to the device, through cooperation of all accessories, wheels of a shield electric locomotive can be automatically limited when the shield electric locomotive stops, the shield electric locomotive is effectively prevented from slipping, the anti-slip iron wedge can be automatically retracted when the shield electric locomotive runs, and thus the safety of the shield electric locomotive is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of shield-tunneled electric locomotives, in particular to an anti-slip wheel device for shield-tunneled electric locomotives. Background technique [0002] In the shield tunnel construction, the horizontal transportation of electric locomotives provides the main tool for tunnel excavation to transport construction materials and muck, and occupies a key position in tunnel construction. In the construction of large-slope shield tunnels, due to the large slope, long distance, and track Wet and slippery reasons may easily lead to poor braking effect or failure of the electric locomotive. Once this situation occurs and the vehicle slips, it will cause serious adverse consequences to the shield equipment, operators, project quality, and corporate image; [0003] In the prior art, during the operation of the shield electric locomotive, the iron shoes are generally placed on the track manually to prevent the locomot...
