The working principle is as follows: when the emergency brake device of the monorail crane is used, a vehicle set with the emergency brake device is firstly installed on a monorail crane rail for use. During normal running of the train, the hand pump 301 pumps hydraulic oil in the oil tank 302 to the oil cylinder 802. The hydraulic oil entering the cylinder 802 pushes out the piston in the direction of the tachometer wheel 6, and the slide block 12 is not between the brake arm assembly 2 and the frame body 1. The brake block 4 is not in contact with the rail and the reciprocating spring 801 is now compressed.
And if the speed of the vehicle group is too large to exceed the set speed threshold, the speed-limiting braking triggering mechanism 7 carries out speed-limiting braking. The method specifically comprises the following steps: the excessive speed causes the centrifugal force of the flinger 7013 to be excessive, the two flingers 7013 are gradually far away, and the movable block 7012 rotates. The movable block 7012 presses the intermediate shaft 7014 downward under the restriction of the stopper 7011, and the intermediate shaft 7014 is pressed downward to contact the stopper 7023 on the mounting disk 7021. The blocking piece 7023 displaces to drive the connecting rod assembly 7022 to also displace, and the connecting rod assembly 7022 drives the pressure release valve to open through the steel wire rope at the moment. The cylinder 802 is vented and hydraulic oil therein flows to the tank 302. Meanwhile, as the oil cylinder 802 is decompressed, the piston of the oil cylinder 802 moves under the elastic action of the reciprocating spring 801. The slide 12 now follows the piston. As shown in fig. 8, the slider 12 is moved between the brake arm assembly 2 and the frame body 1 so that the brake arm assembly 2 is rotated centering on the first pin shaft 9. The distance between the bottom ends of the inner surfaces on both sides of the brake arm assembly 2 increases, and the distance between the top ends of the inner surfaces on both sides of the brake arm assembly 2 decreases. Thereby causing the brake shoes 4 to approach each other and clamp the track, thereby achieving a braking effect. After the speed is limited by braking, the swinging block 7013 returns to the original position, and the middle shaft 7014 also returns to the original position under the elastic action of the return spring 7015 and does not extrude the baffle 7023 any more. The linkage assembly 7022 returns to its original position and the relief valve closes. The piston of the oil cylinder 802 moves again to drive the slide block 12 to exit between the brake arm assembly 2 and the frame body 1, and the vehicle set runs normally. Meanwhile, with the withdrawing of the sliding block 12, the brake arm assembly 2 is rapidly restored to the original position under the action of the first torsion spring 10.
If an emergency situation occurs, the worker can perform emergency braking through the manual braking assembly 3. The method specifically comprises the following steps: the hand pump 301 is turned off and hydraulic oil is stopped from being pressed into the cylinder 802. At this time, the cylinder 802 is piston-moved by the elastic force of the reciprocating spring 801. Excess hydraulic oil spills from the piston clearance back into the tank 302, while the slide 12 now follows the piston of the cylinder 802. The slide block 12 is moved between the brake arm assembly 2 and the frame body 1 so that the brake arm assembly 2 is rotated about the first pin 9. The distance between the bottom ends of the inner surfaces on both sides of the brake arm assembly 2 increases, and the distance between the top ends of the inner surfaces on both sides of the brake arm assembly 2 decreases. Thereby causing the brake shoes 4 to approach each other and clamp the track, thereby achieving a braking effect. When manual braking is not needed, the hydraulic oil is pressed into the oil cylinder 802 again only through the hand pump 301.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
