According to the braking clamp provided by the embodiment, under the action of the hand-pulling relieving mechanism 1, the power mechanism 2 unloads braking force, under the action of the power mechanism 2, the driving motion assembly 3 moves around the supporting piece 6, the motion assembly 3 moves to drive the braking assembly 4 to move, braking or relieving is achieved, and the specific working principle is as follows:

during normal braking, the power mechanism 2 pushes the moving assembly 3 to rotate around the support 6, so as to drive the first braking component 41 and the second braking component 42 to approach each other until the first braking component 41 and the second braking component 42 compress the brake disc, so as to generate a braking force, thereby realizing braking of the rail train.

In normal release, the power mechanism 2 pushes the moving assembly 3 to rotate around the support 6, so as to drive the first braking component 41 and the second braking component 42 to move away from each other until the first braking component 41 and the second braking component 42 release the brake disc, and the braking force is unloaded, so as to realize the braking of the rail train.

When the manual release is performed, the first transmission member 115 is pulled by hand, the first transmission member 115 pulls the movable pulley 113 to move, the telescopic rod 121 is driven to slide in the fixed rod 122 (i.e. the telescopic assembly 12 is extended), the fixed rod 122 rotates counterclockwise, the second release member 135 is driven to rotate, at this time, the first contact point 13311 and the second contact point 13312 of the first contact portion 1331 and the fastening member 134 form a moment balance, so as to realize locking, thereby converting the pulling force into a torque to the second transmission member 231 of the power mechanism 2, converting the torque into an axial force, pushing the third transmission member 232, further transmitting the axial force to the fourth transmission member 233 to move forward (i.e. the direction of the pressing plate member 5), because the brake applying state is maintained at this time, the fifth transmission member 234 is pressed against the pressing plate member 5 and cannot move forward, the fourth transmission member 233 cannot move forward, therefore, the fourth transmission member 233 receives a reaction force and transmits the reaction force to the third transmission member 232, and then transmitted to the end cap 22 by the second transmission part 231, because the end cap 22 is in threaded connection with the guide shaft 24, a reaction force is applied to the spring part 242, the spring part 242 compresses, the guide shaft 241 drives the locking part 25 to move backward (i.e. in the direction opposite to the pressing plate part 5), the saw teeth of the first clamping part 2331 are disengaged, so that the fourth transmission part 233 is released, the non-self-locking thread pair between the fourth transmission part 233 and the fifth transmission part 234 receives an axial force to generate a torque, and then rotates clockwise, so that the fifth transmission part 234 moves backward, so that the first moving part 31 and the second moving part 32 rotate around the support part 6, and further the first braking part 41 and the second braking part 42 generate a gap with the brake disc, and mechanical relief is realized. After the mechanical relief, the tension member 14 pulls the fixing rod 122 to rotate clockwise to reset (i.e. the telescopic assembly 12 retracts), and then the second relief member 135 rotates clockwise, at this time, the first contact point 13311 of the first contact portion 1331 is pulled by a single point to move the first relief member 133 to rotate freely around the fastening member 134, so that the second relief member 135 cannot transmit torque, and the problem of re-braking during the resetting process is avoided.
