Further, when the friction block 13 is worn to a certain degree, the hydraulic oil compensates the stroke of the piston rod 11, and when the hydraulic oil compensates the stroke of the piston rod 11, the stroke of the piston rod 11 is increased, and further the stroke of the sliding rod 14 is also increased, and at this time, the trigger block 15 connected to the sliding rod 14 contacts with the pressure sensitive element on the pressure sensor 52, so that the pressure sensor 52 sends out a signal, and the signal is transmitted to the inside of the circuit control box 51 through the lead 53.
Further, the elements inside the circuit control box 51 receive signals to process, and the valve inside the oil inlet bin 41 is started to open the oil inlet hole 42, so that hydraulic oil enters the oil inlet bin 41 and then enters the oil inlet channel 431 from the inside of the oil inlet bin 41 to push the piston 441 inside the piston channel 432, when the piston 441 moves, the push rod 442 drives the compensation block 443 inside the compensation channel 433 to enter the compensation groove 12, after braking is finished, the trigger block 15 leaves the pressure sensor 52, at this time, the valve is closed, the compensation block 443 is always located inside the compensation groove 12, when the piston rod 11 is reset, the original position cannot be returned, and when the next braking is finished, the moving stroke of the piston rod 11 is consistent with the moving stroke before the friction block 13 is worn.
Further, when replacing the new friction block 13, the replacing person manually touches the pressure sensitive element of the pressure sensor 52 to open the oil inlet 42, so that no pressure exists inside the oil inlet tank 41, at this time, the pushing block pushes the reset ejecting block 631 to move through the connecting rod by pushing the pushing block, the reset ejecting block 631 pushes the compensation block 443 back inside the compensation channel 433 by entering the compensation groove 12 through the groove 8, and leaves the touched pressure sensor 52 to close the oil inlet 42 of the oil inlet tank 41, and then resets the pushing block.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
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.
