When the vehicle runs, if the main power supply is in power-off state or needs emergency stop under the condition of danger fault, and the electric brake is in fault temporarily, the vehicle can continue to slide by inertia, and the vehicle can collide with equipment and an operation room on the ground, so that certain economic loss is caused, and therefore an emergency auxiliary brake system needs to be designed.
Disclosure of Invention
The utility model discloses a main objective is in order to solve the problem that exists when the above-mentioned driving operation, provides the emergent auxiliary brake system of bridge crane.
The utility model has the following concrete scheme: bridge crane emergency auxiliary brake system, the on-line screen storage device comprises a base, two mutual disposition's brake support are equipped with on the base, brake support bottom is rotated with the base and is connected, two brake supports arrange the both sides at the drive shaft respectively, one side that every brake support is close to the drive shaft is equipped with an arc brake disc, it is equipped with spring return mechanism to lie in the drive shaft top between two brake supports, spring return mechanism is used for making two arc brake discs be in the state that breaks away from the drive shaft, a triangle connecting plate is equipped with on the brake support A top among two brake supports, an angle of triangle connecting plate is articulated with brake support A, second angle rotation is connected with a connecting rod, the other end and the brake support B top of connecting rod are rotated and are connected, a third angle is connected with a wire rope, wire rope one end is connected to the control room, brake pedal is equipped with in the control room, brake pedal and wire rope fixed connection.
Spring return mechanism includes a connecting rod, and connecting rod one end is rotated with brake support B and is connected, the other end and brake support A sliding connection, and the cover is equipped with a pressure spring on the connecting rod.
Arc brake disc outer end is connected with the brake support rotation, and arc brake block that matches with the drive shaft is equipped with to arc brake disc inboard.
The utility model discloses lie in on the hoist and be equipped with a plurality of leading wheel between base and the control room, wire rope walks around behind the leading wheel in proper order and is connected with brake pedal.
The utility model discloses a theory of operation as follows: when power supply is in a power supply trip or an electric braking system is in a fault temporarily and needs emergency braking, the brake pedal is stepped to drive the steel wire rope, the steel wire rope drives the triangular connecting plate to rotate and drives the connecting rod and the brake supports to move, and the two brake supports are close to the driving shaft and clamped to realize emergency braking; after the pedal is released, the two brake brackets are automatically separated from the driving shaft under the action of the spring return mechanism.
Compared with the prior art, the utility model has the following advantages: the crane can be ensured to be braked emergently in emergency, and the lifting operation is safe.
