The invention relates to the technical field of special equipment, and discloses a two-way progressive brake safety tongs, in which a force plate is movably sleeved on the outer surface of the center shaft, the number of force plates is two, and one end of the force plate is fixed A trigger is installed, and the outer surface of the coil drum is in contact with the outer guide rail. When the device is working, the triggers on the upper and lower sides will move simultaneously, so that the brake bar will continue to collide with the trigger on the other side for a second time after hitting the upper trigger, making the braking effect more obvious. At the same time, the brake bar The self-rotating force generated when hitting the upper trigger can be transmitted to the contact position between the lowered trigger and the outer guide rail, so as to avoid the force plate on one side taking the axis of the central axis as the center of rotation due to too severe impact Rotation causes the position of the trigger to deviate and loses the frictional force between the outer guide rail and the whole device loses its effect, which improves the working stability of the device.

The invention discloses an early-warning device capable of tracking a fault at the front end of a vehicle vacuum brake. The early-warning device comprises a body, a front end early-warning signal device (15), a tail end early-warning signal device (19) and an engine rotation speed pulse signal obtaining device (20). The body comprises a shell, a loudspeaker (6) arranged in the shell, and a circuit board (3) connected with the loudspeaker. The circuit board comprises a power source circuit, a control circuit, a voice circuit, a power amplifier circuit and a waveshaping circuit. The power source circuit provides two different voltages for the power amplifier circuit, the waveshaping circuit, the control circuit and the voice chip circuit through voltage reduction. The front end early-warning signal device and the tail end early-warning signal device are connected with the control circuit. The control circuit is connected with the voice circuit and the power amplifier circuit. By the adoption of the early-warning device, the effect that a vehicle has enough time to be processed with effective measures before the vehicle completely loses braking capacity can be guaranteed, safety of a driver and other personnel on the vehicle is guaranteed, and reliability and accuracy of early-warning can be guaranteed.
