As shown in the attached figure 1, the broken belt catcher of the multiplication torque belt conveyor comprises a frame 12, a balancing weight 3, an upper catching frame 5, a movable pulley 4 and a rope 14; the rack 12 comprises two side walls, one end of the upper capturing frame 5 is connected with the capturing block 6, and the other end of the upper capturing frame is connected with the side walls of the rack 12 in a rotatable mode; the upper part between the two side walls is fixedly connected with an upper cross beam 1 matched with the catching block 6 of the upper catching frame 5; the side edge of the upper capturing frame 5 is connected with a movable pulley 4, and the rack 12 is also connected with a reversing structure for reversing the rope 14; one end of the rope 14 is fixedly connected with the frame 12, and the other end of the rope is fixedly connected with the balancing weight 3 keeping the falling trend after sequentially passing around the movable pulley 4 and the reversing structure; the movable pulley 4 is creatively used for improving the catching effect, the same weight provides larger catching force, the structure is simple, the production and installation of products are not influenced, the stability is not required to be ensured by increasing the weight of the rack 12, and the potential safety hazard of swinging of the counterweight arm is avoided.
The height of the reversing structure in the vertical direction is not lower than the position of the movable pulley 4 when the catching block 6 of the upper catching frame 5 rotates to the highest point; the catching blocks 6 of the upper catching frame 5 can be ensured to rotate to the highest point and catch the upper belt 10.
An upper carrier roller 13 capable of rotating relative to the upper capturing frame 5 is arranged at the upper part of the upper capturing frame 5, and the upper carrier roller 13 enables rolling friction to exist between the belt and the upper capturing frame 5, so that abrasion between the belt and the upper capturing frame 5 is reduced.
The rope 14 passes by the movable pulley 4 from bottom to top; after the belt is broken, the upper belt 10 cannot give enough pressure to the upper carrier roller 13, and the upper capturing frame 5 can be ensured to capture the upper belt 10 quickly under the traction of the rope 14 in a mode of winding from bottom to top; the broken belt catcher of the multiplication torque belt conveyor further comprises a lower catching frame 11, one end of the lower catching frame 11 is connected with the catching block 6, and the other end of the lower catching frame 11 is connected with the side wall of the rack 12 in a rotatable mode; the lower part of the lower capturing frame 11 is provided with a lower carrier roller 8 which can rotate relative to the lower capturing frame 11; the upper catching frame 5 and the lower catching frame 11 are arranged between the lower belt 9 and the upper belt 10 of the conveying belt; the lower part between the two side walls is fixedly connected with a lower beam 7 matched with the catching block 6 of the lower catching frame 11; meanwhile, the upper catching frame 5 and the lower catching frame 11 are arranged, so that the broken upper belt 10 and the broken lower belt 9 can be caught and fixed, and the belts are prevented from sliding under the action of gravity.
The side edges of the two sides of the upper capturing frame 5 are both connected with movable pulleys 4, and two sides of the rack 12 are respectively provided with a group of ropes 14 and a group of balancing weights 3 which are matched with the movable pulleys 4 on the same side; the movable pulleys 4, the ropes 14 and the balancing weights 3 on the two sides are symmetrical about the central axis of the frame 12. The catching force of the two sides is the same and uniform while catching, and secondary damage to the belt is prevented.
Example 2
As shown in fig. 2, on the basis of the broken belt catcher of the multiplication torque belt conveyor in embodiment 1, the reversing structure is aligned with the upper edge of the movable pulley 4 when the catching block 6 of the upper catching frame 5 rotates to the highest point in the vertical direction; the connecting point of one end of the rope 14 and the frame 12 is flush with the lower edge of the movable pulley 4 when the catching block 6 of the upper catching frame 5 rotates to the highest point.
When the catching block 6 of the upper catching frame 5 rotates to the highest point, the ropes 14 on the two sides of the movable pulley 4 are in a horizontal state and are parallel to each other, so that the upper catching frame 5 receives the maximum resultant force, and the catching stability is highest.
Example 3

In the running process of the belt conveyor, the belt and the load on the belt vibrate and fluctuate up and down, and the catching block 6 of the upper catching frame 5 constantly props against the lower surface of the upper belt 10, so that the upper catching frame 5 can continuously swing around a rotating shaft of a rotating connection joint part of the upper catching frame 5 and the rack 12; however, the counter weight block 3 is pulled to the upper catching frame 5 at any moment, so that the rotating shaft can bear destructive force with variable size and uncertain direction at any moment, and the service life of the rotating shaft is seriously influenced; absorbing such destructive forces by the damper springs can extend the useful life of the shaft.
In the conventional broken belt catching device, a counterweight directly acts on a pin shaft (rotating shaft) which rotates around an upper catching frame 5, and the pin shaft not only constantly bears destructive force caused by size change and indefinite direction of a belt due to vibration and up-and-down fluctuation, but also constantly and directly bears all direct shearing force generated by the counterweight and the upper catching frame 5, so that the service life is seriously influenced; and in case the round pin axle fracture, as the joint portion of "counter weight structure" and last capture frame 5, it is comparatively troublesome to change, if used "counter weight arm" in the structure of counter weight, the counter weight arm swing by a wide margin that the sudden fracture brought is a huge potential safety hazard.
The utility model discloses in, movable pulley 4 sets up and is catching a side, and the gravity of balancing weight 3 can transmit whole catching a side, and the pivot can not directly bear the weight and catches the whole shearing force that 5 produced with last catching, and the adverse effect to the countershaft reduces greatly. The arrangement of the movable pulley 4 not only solves the problem of the capturing force, but also is one of the conditions for prolonging the service life of the rotating shaft, and achieves the double-layer beneficial effects of improving the capturing force and prolonging the service life of the rotating shaft. Meanwhile, the movable pulley 4 is arranged on the side of the catching frame, the upper carrier roller 13 is connected with the upper catching frame 5 through the damping part, and the two structural connection relations are achieved simultaneously, so that the service life of the rotating shaft is further prolonged greatly.
Except for the technical features described in the specification, the method is known to the technical personnel in the field.
