It is an object of the invention to provide a kind of urgent anti roll device for metro shield electric haulage locomotive.
The technical scheme is that, a kind of urgent anti roll device for metro shield electric haulage locomotive, equipped with braking underframe on vehicle frame, equipped with urgent anti roll device on braking underframe；Described urgent anti roll device includes that the cylinder body end of hydraulic cylinder or cylinder, hydraulic cylinder or cylinder is contained in the expansion link of vehicle frame, hydraulic cylinder or cylinder and is contained on connecting lever by rotary shaft, being contained on braking underframe of connecting lever axle；Equipped with brake arm spill spin block on connecting lever axle, at brake arm spill spin block equipped with a pair brake arm, described brake arm upper end has slot, brake arm axis hole is had in socket sidewalls, brake arm spill spin block is contained in the slot of brake arm, installing axle equipped with braking on brake arm spill spin block, brake arm is contained in brake arm by brake arm axis hole and installs on axle；Being also equipped with brake arm lead-frame on braking underframe, brake arm is inserted in the inside casing mouth of brake arm lead-frame, and inside casing mouth two side is inclined-plane.
Brake arm spill spin block is bolted on camshaft.
Having socket on the lateral wall of brake arm lead-frame one end, equipped with cutting on braking underframe medial wall, in the socket nesting on the lateral wall of brake arm lead-frame in cutting, the other end of brake arm lead-frame is braked on underframe by fixing being bolted to.
Equipped with wear plate at brake arm jaw.
The present invention has the following technical effect that, uses the operation of driver's handle to control hydraulic cylinder or cylinder makes its action, and then make the jaw side of clamping left and right sides rail, stop electric locomotive under braking drawing strickle guide guides of mechanism's brake arm.This device has the advantage that one is simple in construction, low cost；Two be device without oil supply, can be non-maintaining；Three is that brake arm lead-frame can adapt to gauge laying error automatically, makes brake arm automatic capturing track all the time；Four is that device has and automatically resets and human assistance reset both of which, adapts to job site；Five is that package unit is easy for installation, it is adaptable to the transformation of electric locomotive is installed additional.
