The utility model is provided with liner with position device 1 between away from the brake rim 2 of pull bar and brake arm 3.Can be spring sheet 27 with position device 1, an end of spring sheet 27 be fixed on the brake arm, the other end and the thermo-contact of braking lining.Can be Returnning spring with position device 1, an end of Returnning spring be fixed on the brake arm, and the other end is fixed on the brake rim.Described can also be torsion spring with position device 1, and an end of torsion spring is fixed on the brake arm, and the other end is stuck on the brake rim.
First brake arm of the present utility model and second retainer walls by etc. move back apart from device 14 and be arranged on the base 13.
Working procedure of the present utility model is as follows: wear limit alarm switch 4, the first pusher throw over switch 9 and the second pusher throw over switch 10 all insert master control system, when break is opened, pusher 11 work, push rod upwards rises rapidly, the second pusher throw over switch 9 is touched, the second pusher throw over switch 10 is separated touches the Brake drum brake off.
During proper functioning, the ratchet of automatic compensator is decided tooth and is moved at two between cog of the moving tooth of ratchet, and namely the space width of the moving tooth of ratchet is consistent to the spacing between Brake drum with the interior brake shoe of brake rim.Under the normal operating condition, as shown in Figure 3, ratchet is decided tooth and is arranged on moving two the tooth neutral positions of tooth of ratchet; During braking, as shown in Figure 6, ratchet is decided tooth at the crown A place of the moving tooth of ratchet; When brake off, as shown in Figure 7, ratchet is decided tooth at the tooth root B place of the moving same tooth of tooth of ratchet; No matter be braking or releasing, it is mobile in the outer rim of a tooth all the time that ratchet is decided tooth, and the moving tooth of gear is just along with the pull bar upper and lower displacement, and self does not rotate.When the brake block abrasion in the brake rim, because design principle, the pusher push rod is bigger than drop under the normal state, just can play braking effect.Ratchet is decided distance that tooth moves with respect to the moving tooth of ratchet just greater than normal state like this.When namely braking, as shown in Figure 8, ratchet is decided tooth enters into the moving tooth of next ratchet under the effect of Returnning spring tooth root C place; During brake off, ratchet is decided tooth along with lever is upwards moving, and the moving tooth of ratchet is along with pull bar is moving downwards, and ratchet is decided tooth like this changes with regard to the moving tooth spiral of handsetting gear, the amplitude of rotation matches with the first thread bush internal thread spacing, just in time makes pull bar consistent with wear extent with the first thread bush displacement amount.
When the friction disc wear of brake rim, when braking, because design principle, pusher 11 push rods are to the whereabouts, and automatic compensator 7 moves downward with respect to pull bar 5, and namely ratchet decide tooth 16 and is moved around the moving tooth 15 of ratchet.When pusher is opened, pusher 11 push rods drive automatic compensator 7 when rising and rise, ratchet decide tooth 16 and will be broadcast the moving tooth 15 of ratchet and rotate and make second brake arm to the close wearing clearance that remedies of Brake drum this moment, liner is spring sheet with position device 1, when second brake arm 3 is close to Brake drum, brake rim 2 is also thereupon near Brake drum, liner utilizes self elasticity to make brake rim 2 upper ends away from Brake drum with position device 1, Deng move back apart from device 14 then since linking mechanism make about folding simultaneously, about assurance with Brake drum gap equalization.
When wear limit alarm switch 4 switches are touched, then need more renewal of facing renewal.
When the pusher fault, master control system does not have any instruction, and the first pusher throw over switch 9 is separated to be touched, the second pusher throw over switch 10 is touched, this moment, the master control system internal processes activated pusher master motor automatically, made break reply normal working immediately, and sent alarm signal.
The working service process is as follows
Break only needs locate centered by Brake drum earlier when just adorning, carry out break action 2-3 time, tightening fixing bolt can use to friction plate and change, when break abrasion limiting alarm switch is reported to the police, the staff carries out friction plate and changes, and changes laggard action and does 2-3 time and can come into operation again.Pusher can fall under the effect of brake spring power when pusher breaks down in the break, excite position limit switch to produce signal at dropping process, pusher master motor is started immediately, make break guarantee normal working, and send warning to arriving the artificial fault that solves to master control system.
