The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of belt conveyer is with join control type broken belt or stall protection device automatically, and it comprises: base plate 1, frame 2, pivoted arm cover 3, pivoted arm main shaft 4, pivoted arm connecting panel 9, on brake brake shoe 10 and braking brake shoe 12 down.Described base 1 is a plate armature, gusset I 1-1 is set below the flat board; Described frame 2 is installed on base plate 1.Described pivoted arm cover 3 is installed on the base plate 1, and pivoted arm overlaps 3 upper ends has shaft block ring 5, and there is bearing platen 13 lower end.Described pivoted arm main shaft 4 is connected with pivoted arm cover 3 with bearing II 16 through bearing I 7, and the pivoted arm main shaft is installed in pivoted arm cover 3 on the base plate 1 with nut I 6 and nut II 14 respectively at two ends about in the of 4, leaves the gap between pivoted arm cover 3 and the base plate 1.Pivoted arm main shaft 4 upper ends are connected with frame 2.Described pivoted arm connecting panel 9 is the template structure, and the one of which end is welded on the pivoted arm cover 3, and the other end is connected with last brake shoe permanent seat 15.Between pivoted arm cover 3 and the pivoted arm connecting panel 9 torsion spring I 8, electromagnetic valve 19 and elasticity pivot pin 20 are set.The described braking brake shoe 10 of going up is installed on the brake shoe permanent seat 15 through last brake shoe rotating shaft 11, on brake brake shoe 10 and overlap 3 through pipe link 17 and pivot pin 18 and pivoted arm and be connected.Between last braking brake shoe 10 and the last brake shoe permanent seat 15 torsion spring II 21 is set.The described brake shoe 12 of braking down is installed on the base plate 1.It is characterized in that: the described driving surface of going up braking brake shoe 10 is arc 10-1, and the extrados of described arc 10-1 is the involute-type cambered surface.The driving surface of the described brake shoe 12 of braking is down made the involute-type deep-slotted chip breaker identical with the driving surface of arc 10-1.
There is rubber plate I 10-2 in the outside of described arc 10-1.Rubber plate II 12-1 is arranged at the top of the described brake shoe 12 of braking down.
During use this device is installed on the belt conveyer frame through W type frame; The upper-lower position of adjustment base plate 1; Make down and keep certain distance between braking brake shoe 12 and the conveyer belt lower surface; When normally moving, conveyer belt all do not contact, in order to avoid the damage conveyer belt with upper and lower braking brake shoe 12.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: when broken belt took place, the conveyer belt that is loaded with material glided, and drove the tachogenerator rotation and produced the pulsed electric signal and send the controller main frame to, count down to when setting pulse the output control signal.The interlock signal is transferred in the controller of arranging the front and back, and shutdown signal passes to main belt control circuit, and all controllers drive electromagnetic valve 19 actions through amplifying circuit; Extract the control pin out, around pivoted arm main shaft 4 Unscrews, pipe link 17 is extracted pivot pin 18 to pivoted arm connecting panel 9 in the rotary course under the 8 elastic force effects of torsion spring I; Last braking brake shoe 10 is in torsion spring II 21 with from centering on brake shoe rotating shaft 11 rotations under the effect of gravity rapidly; Arc 10-1 descends, and rubber plate I 10-2 contacts with the conveyer belt upper surface, and the drive of conveyer belt upper surface is gone up braking brake shoe 10 and continued to be rotated down; Distance between belt and the bottom braking brake shoe 12 is more and more littler; Conveyer belt compresses the most at last, until stop motion, reaches the purpose of broken belt protector.There is rubber plate I 10-2 in the outside of arc 10-1, and rubber plate II 12-1 is arranged at the top of the described brake shoe 12 of braking down, and purpose is to increase with the friction brake force of belt not damage belt again.
Like accompanying drawing 1,2, shown in 3, on to brake brake shoe 10 be the outside that is positioned at the belt conveyor frame when normal condition, adapt to different flow travelling belt installation down, can not run into the material that is transporting, normally move in order to avoid influence belt conveyor.
