Description
Technical field
The utility model relates to a kind of Novel broken belt grabber.
Background technology
The catching device of the use of belt conveyer protection at present has the multiple technologies scheme, but considerable part has wherein all adopted swing brake shoe formula principle.Wedge shape brake shoe in these catching devices is fixed on upper rack or outside, when broken belt occurs, drives brake shoe by certain Power Drive Unit and swings, and reduces the gap between brake shoe and drive wheel, and belt is implemented to arrest., if according to the propulsion source difference, divide, can be divided into two kinds: i.e. friction-driving and electric-liquid type; The former driven roller is positioned at the load-transfer device below, is centering type or ratchet inverse-stopping type, and drive wheel normally rotates when load-transfer device normally moves.During broken belt, utilize the retrograde friction force that produces of load-transfer device to make driven roller drive the transmission device action, brake shoe is arrested; The latter broken belt detecting sensor check broken belt signal, drive the brake shoe action by electro-hydraulic device and implement to arrest.
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, only arrest load-transfer device both sides of the edge part while arresting, arrest piece and the load-transfer device area of contact is little, large to the 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 the load-transfer device antikinesis, the catching device action is sent out in generation place,, so when upper fortune conveyer stops, make the load-transfer device short range reverse fashion, be easy to cause misoperation.
Novel broken belt grabber 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 misoperation not occur because conveyer stops or reverses, during belt conveyer generation belt phenomenon, can guarantee that the up and down load-transfer device is arrested simultaneously by actv., reliability is high, and the up and down 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 Novel broken belt grabber.
The purpose of this utility model is achieved through the following technical solutions:
Novel broken belt grabber of the present utility model, comprise upper spider, entablatrance, upper support frame, upper pivot arm, upper friction shoe, upper supporting roller, torsion spring, lower bearing bracket, cross sill, lower support frame, lower pivot arm, lower friction shoe and snub pulley.entablatrance and upper spider are bolted, upper support frame is connected by bearing with upper spider, upper support frame and bearing inner ring interference fit, upper spider and outside race interference fit, upper pivot arm is connected by torsion spring with upper support frame, upper friction shoe is located at the pivot arm front end, upper supporting roller is located at the pivot arm upside, cross sill and lower bearing bracket are bolted, the lower support frame is connected by bearing with lower bearing bracket, lower support frame and bearing inner ring interference fit, lower bearing bracket and outside race interference fit, 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.
Can be found out by the technical scheme that above-mentioned the utility model provides, Novel broken belt grabber 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 misoperation not occur because conveyer stops or reverses, during belt conveyer generation belt phenomenon, can guarantee that the up and down load-transfer device is arrested simultaneously by actv., reliability is high, the up and down 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.
Description of drawings
Fig. 1 is that Novel broken belt grabber is at the normal run time organization schematic diagram of belt conveyer;
Fig. 2 is Novel broken belt grabber structural representation when belt conveyer generation broken belt.
The specific embodiment
Novel broken belt grabber of the present utility model, as shown in Figure 1 and Figure 2, Novel broken belt grabber comprises upper spider 1, entablatrance 2, upper support frame 3, upper pivot arm 4, upper friction shoe 5, upper supporting roller 6, torsion spring 7, lower bearing bracket 8, cross sill 9, lower support frame 10, lower pivot arm 11, lower friction shoe 12 and snub pulley 13 to its better specific embodiment.
Novel broken belt grabber of the present utility model has following innovative point:
The upper pivot arm of Novel broken belt grabber is connected by torsion spring with upper support frame, can guarantee Novel broken belt grabber arresting fast load-transfer device by actv..
Be described further below in conjunction with the principle of work of accompanying drawing to Novel broken belt grabber:
When belt conveyer normally moves, as shown in Figure 1, rely on the tension force of load-transfer device, the upper supporting roller of upper pivot arm upside contacts with load-transfer device, can rotate with the operation of belt conveyer, this moment, torsion spring was in compressive state, and the snub pulley of lower pivot arm downside contacts with load-transfer device, can rotate with the operation of belt conveyer;
When belt conveyer generation broken belt accident, as shown in Figure 2, (this is load-transfer device generation broken belt the moment of fault in the tension force meeting rapid drawdown of load-transfer device, energizing signal the most accurately), load-transfer device occurs to relax and glide, arresting frame on this moment rotates up under the driving to the friction shoe friction force at torsion spring torsion and load-transfer device until arrest between friction shoe and entablatrance to form and arrest gap and arrest load-transfer device, under arrest frame be rotated down under the self gravitation effect and cross sill between form and to arrest gap and arrest load-transfer device, thereby effectively implement to arrest, Accident prevention further occurs.
The beneficial effects of the utility model are:
Compactness rational in infrastructure;
Rely on the tension force of induction belt of belt conveyor to realize broken-belt catching, can misoperation not occur because conveyer stops or reverses;
During belt conveyer generation belt phenomenon, can guarantee that the up and down load-transfer device is arrested simultaneously by actv., reliability is high;
The up and down friction shoe contacts with carrying zone face, and actv. has reduced the damage to load-transfer device, has extended the service life of load-transfer device.
The above; it is only the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
