All there are following one or more shortcomings in above-mentioned catching device scheme, is mainly: the first, and catching device and conveyer share a frame, and its intensity is lower, and while arresting, frame may produce distortion; The second, while arresting, only arrest load-transfer device both sides of the edge part, arrest piece and load-transfer device area of contact is little, large to load-transfer device infringement; The 3rd, drive disk assembly is many, and dust and material are easy to block the motion of movable part, has reduced the reliability of arresting; The 4th, because they are that while utilizing load-transfer device antikinesis, catching device action is sent out in generation place, so make load-transfer device short range reverse fashion when upper fortune conveyer stops, be easy to cause misoperation.
Torsion type belt conveyer broken belt catcher of the present utility model compactness rational in infrastructure, rely on the tension force of induction belt of belt conveyor to realize broken-belt catching, can there is not misoperation because conveyer stops or reverses, during belt conveyer generation belt phenomenon, can guarantee that upper and lower load-transfer device is arrested simultaneously by actv., reliability is high, and upper and lower friction shoe contacts with carrying zone face, actv. has reduced the damage to load-transfer device, has extended the service life of load-transfer device.
Summary of the invention
The purpose of this utility model is to provide a kind of torsion type belt conveyer broken belt catcher.
The purpose of this utility model is achieved through the following technical solutions:
Torsion type belt conveyer broken belt catcher of the present utility model, comprises upper spider, entablatrance, reinforcement gusset, lower bearing bracket, cross sill, bearing seat, upper support frame, spring case, upper pivot arm, upper friction shoe, upper supporting roller, supporting seat, lower support frame, lower pivot arm, lower friction shoe, snub pulley and volute spiral spring.Entablatrance and upper spider are bolted, strengthening gusset and upper spider is bolted, strengthening gusset and lower bearing bracket is bolted, cross sill and lower bearing bracket are bolted, bearing seat is bolted with reinforcement gusset, upper support frame and bearing seat mesh fixing by gear, spring case is connected by volute spiral spring with upper support frame, volute spiral spring one end is located in the groove of upper support frame, the other end is connected with spring case, upper pivot arm and spring case are bolted, upper friction shoe is located at pivot arm front end, upper supporting roller is located at pivot arm upside, supporting seat is bolted with reinforcement gusset, lower support frame two ends are located in supporting seat, lower pivot arm and lower support frame interference fit, lower friction shoe is located at lower pivot arm front end, snub pulley is located at lower pivot arm downside.
The technical scheme being provided by above-mentioned the utility model can be found out, torsion type belt conveyer broken belt catcher described in the utility model, compactness rational in infrastructure, rely on the tension force of induction belt of belt conveyor to realize broken-belt catching, can there is not misoperation because conveyer stops or reverses, during belt conveyer generation belt phenomenon, can guarantee that upper and lower load-transfer device is arrested simultaneously by actv., reliability is high, upper and lower friction shoe contacts with carrying zone face, actv. has reduced the damage to load-transfer device, has extended the service life of load-transfer device.
Accompanying drawing explanation
Fig. 1 is that torsion type belt conveyer broken belt catcher is at the normal run time organization schematic diagram of belt conveyer;
Fig. 2 is torsion type belt conveyer broken belt catcher structural representation when belt conveyer generation broken belt;
Fig. 3 is the main TV structure schematic diagram of torsion type belt conveyer broken belt catcher.
The specific embodiment
Torsion type belt conveyer broken belt catcher of the present utility model, its preferably the specific embodiment as shown in Figure 1, Figure 2, Figure 3 shows, torsion type belt conveyer broken belt catcher comprises upper spider 1, entablatrance 2, strengthens gusset 3, lower bearing bracket 4, cross sill 5, bearing seat 6, upper support frame 7, spring case 8, upper pivot arm 9, upper friction shoe 10, upper supporting roller 11, supporting seat 12, lower support frame 13, lower pivot arm 14, lower friction shoe 15, snub pulley 16 and volute spiral spring 17.
Torsion type belt conveyer broken belt catcher of the present utility model has following innovative point:
The spring case of torsion type belt conveyer broken belt catcher is connected by volute spiral spring with upper support frame, volute spiral spring one end is located in the groove of upper support frame, the other end is connected with spring case, the power decrement that during broken-belt catching, volute spiral spring provides is little, can actv. guarantees the reliability of broken-belt catching;
The entablatrance of torsion type belt conveyer broken belt catcher and upper spider junction are provided with puller bolt, have improved the safety of broken belt catcher, the vibration of equipment while can actv. preventing broken-belt catching;
